                                    ADFORCE
 
   
        AdForce is a leading provider of centralized, outsourced ad management
and delivery services on the Internet. Our highly reliable, scalable technology
infrastructure and data centers currently deliver up to 210 million ads per day.
Our services offer sophisticated ad campaign design, inventory management,
targeting, delivery, tracking, measuring and reporting capabilities. Our
technology infrastructure and services leverage the advantages of Internet
advertising and direct marketing and allow our customers to:
    
 
        - Reach large or targeted audiences across multiple Web sites on our
          common platform;
 
        - Maximize return on advertising investments for advertisers and ad
          agencies;
 
        - Maximize the value of page view inventories for Web sites and ad rep
          firms;
 
   
        - Monitor and measure the effectiveness of ad campaigns;
    
 
   
        - Modify ad campaigns based on campaign performance data;
    
 
   
        - Aggregate large numbers of sites into a single network and segment the
          network into groups of special interest content such as sports or
          finance; and
    
 
        - Take advantage of direct marketing opportunities using sophisticated
          targeting technologies supported by our large and growing database of
          user information.
 
   
        By outsourcing the technically complex and operationally demanding ad
management and delivery functions to AdForce, our customers can rely on our high
performance systems, technology and personnel while focusing on their own core
competencies.
    
 
   
        Rapid expansion of the Internet has led to significant growth in
electronic commerce. 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.
    
 
   
        Our objective is to be the primary technology and service infrastructure
for advertising and direct marketing on the Internet. We intend to achieve this
objective by:
    
 
   
        - Enhancing and expanding our core technology infrastructure;
    
 
   
        - Leveraging and expanding our customer base;
    
 
   
        - Maintaining our neutrality between the buyers and sellers of
          advertising;
    
 
   
        - Leveraging our database marketing capabilities; and
    
 
   
        - Targeting additional advertising media as they converge with the
          Internet.
    
 
   
        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. 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.
    
 
   
        We incorporated in California as Imgis, Inc. on January 16, 1996 and
intend to reincorporate in Delaware as AdForce, Inc. in April 1999. Our address
is 10590 North Tantau Avenue, Cupertino, California 95014, and our telephone
number is (408) 873-3680. Information contained on our Web site is not a part of

                                  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.
    
 
WE HAVE A LIMITED OPERATING HISTORY
 
   
        We were incorporated in January 1996 and have a limited operating
history. Before buying our common stock, 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. Please see "Management's Discussion and Analysis of
Financial Condition and Results of Operations" for detailed information on our
limited operating history.
    
 
OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE AND OUR FUTURE OPERATING RESULTS
  REMAIN UNCERTAIN
 
   
        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 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 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. 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 relative to our expenses, our business and quarterly and annual results
of operations would be materially and adversely affected.
    
 
WE HAVE A HISTORY OF LOSSES AND EXPECT FUTURE LOSSES
 
   
        We have not achieved profitability and 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 business and 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, $15.0 million for year ended December 31, 1998,
and $4.8 million for the three months ended March 31, 1999. As of March 31,
1999, our accumulated deficit was $29.0 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 lowered quickly even if we fail to generate significant revenue.
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.
Even if we do achieve profitability, we cannot assure you that we can sustain or
increase profitability on a quarterly or annual basis in the future.
    
 
                                       6

WE DEPEND ON A SMALL NUMBER OF CUSTOMERS FOR OUR REVENUE
 
   
        We derive a substantial portion of our net revenue from a small number
of Web sites and ad rep firms. 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. 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, including those
with 24/7 Media, Adsmart, GeoCities and Netscape, can generally be terminated at
any time with little or no penalty. 24/7 Media, Adsmart and Netscape also use
other ad management and delivery systems for a portion of their ad delivery
needs and could reduce or eliminate their use of our services. Please see
"--Consolidation in the Internet Industry May Adversely Affect Our Relationships
with Our Customers."
    
 
CONSOLIDATION IN THE INTERNET INDUSTRY MAY ADVERSELY AFFECT OUR RELATIONSHIPS
  WITH OUR CUSTOMERS
 
   
        Many of our principal customers are now and may in the future be
affected by rapid consolidation in the Internet industry. Our business and
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. GeoCities,
one of our largest customers, has entered into an agreement to be acquired by
Yahoo!. Netscape, another of our largest customers, has been acquired by America
Online. 2CAN Media, another of our largest customers, has been acquired by
Adsmart, a subsidiary of CMG Investments. CMG Investments owns Engage, which
recently acquired Accipiter, one of our competitors. Both Yahoo! and America
Online currently operate their own proprietary ad delivery technologies. 24/7
Media acquired its own ad 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.
    
 
   
ANY INABILITY TO SCALE OUR TECHNOLOGY INFRASTRUCTURE WOULD ADVERSELY AFFECT OUR
  BUSINESS
    
 
   
        We must scale our technology infrastructure to meet the rapidly
expanding market for Internet advertising. If we are unable to scale our
technology infrastructure, we would have difficulty retaining existing customers
and attracting new customers, which would materially and adversely affect our
business and quarterly and annual results of operations. 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.
Our technology and infrastructure may not be able to support higher volumes of
ads, additional customers or new types of advertising or direct marketing.
    
 
   
        We currently deliver most of our ads from our data center in Costa Mesa,
California, and began to deliver ads from our second data center in Cupertino,
California in April 1999. We may be unable to continue to scale our Costa Mesa
and Cupertino data centers on time or within budget. The uninterrupted
performance of our data centers is critical to our success. We expect to add
more ad management and delivery 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.
To the extent that we do not address any capacity constraints effectively, our
business and quarterly and annual results of operations would be materially and
adversely affected. Please see "Business--Technology and Data Center Operations"
for detailed information on our system capacity.

ANY INABILITY TO RESPOND TO RAPID TECHNOLOGICAL CHANGE WOULD ADVERSELY AFFECT
  OUR BUSINESS
    
 
   
        If we are unable to improve our technology infrastructure to respond to
technological change, changes in customer requirements or preferences, or
emerging new industry standards, our business and quarterly and annual results
of operations would be materially and adversely affected. The Internet and the
Internet advertising industry are characterized by rapid technological change,
changes in customer requirements and preferences, frequent new service offerings
and the emergence of new industry standards and practices that could render our
technology and systems obsolete. To remain competitive, we must continue to
improve the performance, functionality and features of our technology
infrastructure. 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 24 hours a day, seven days a week
operation, 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, such as the
delivery of new and complex methods of Internet advertising. We cannot assure
you that we can make any of these improvements in a timely or cost-effective
manner, if at all. For example, in August 1998, we encountered 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.
    
 
   
ANY INABILITY TO ATTRACT AD AGENCIES AND ADVERTISERS AS CUSTOMERS WOULD
  ADVERSELY AFFECT OUR BUSINESS
    
 
   
        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. 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, which would materially and adversely affect our
business and quarterly and annual results of operations. 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 EXTREMELY COMPETITIVE MARKET FOR INTERNET
  AD MANAGEMENT AND DELIVERY SERVICES
    
 
   
        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 upon many factors
within and beyond our control, 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;
 
                                       8
<PAGE>
        - timeliness and market acceptance of new services and enhancements to
          existing services introduced by us or our competitors;
 
        - consolidation among existing customers, potential customers and our
          competitors;
 
        - sales and marketing efforts 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 still
evolving and 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, such as
America Online and Yahoo!, possess proprietary ad serving technologies and could
decide to enter the market for outsourced Internet advertising solutions, or
could reduce our customer base by acquiring existing or potential customers and
shifting those customers to their internal systems. Barriers to entering the
Internet advertising market are relatively low. We may encounter new
competitors, such as Microsoft or IBM, that have longer operating histories,
greater name recognition, larger customer bases or significantly greater
financial, technical and marketing resources than we do. As a result, it is
possible that new competitors may emerge and rapidly acquire significant market
share.
    
 
   
MANY OF OUR CUSTOMERS HAVE LIMITED OPERATING HISTORIES, ARE UNPROFITABLE AND MAY
  NOT BE ABLE TO PAY FOR OUR SERVICES
    
 
   
        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 business and quarterly and annual results of
operations could 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
  BUSINESS
    
 
   
        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. 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. Despite precautions we have taken, unanticipated problems affecting our
systems could in the future cause temporary interruptions or delays in the
services we provide. 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. Sustained or repeated system failures or delays would affect our
reputation, which would materially and adversely affect our business and
quarterly and annual results of operations. 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 business and quarterly and annual results of operations would be
materially and adversely affected by any serious and prolonged emergency.
    
 
                                       9
<PAGE>
   
ANY INABILITY TO TARGET ADVERTISEMENTS WOULD ADVERSELY AFFECT OUR BUSINESS
    
 
   
        New technology allowing Internet advertisers to target their ads to
particular consumers will likely develop at a rapid pace in the near future. If
we are unable to continue to meet the needs of our customers or the marketplace
for more sophisticated advertising solutions, our business and quarterly and
annual results of operations would be materially and adversely affected. As more
advertisers demand such 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. In addition, the use of
demographically targeted advertisements may become subject to adverse
governmental regulation or public pressure, which could deter some potential
customers from using our services.
    
 
CONCERNS FOR PRIVACY ON THE INTERNET MAY ADVERSELY AFFECT OUR BUSINESS
 
   
        Increased regulation of privacy poses a potential risk to our business.
We have invested and continue to invest in technology that could make it easier
to target advertisements to users in specific demographic groups. Advocates of
privacy rights have voiced concern over the implications of this type of
technology. The resolution of privacy issues could adversely affect the growth
both of the Internet and of our business. Our business also depends on placing
information, often referred to as cookies, on a user's hard drive. Our
technology uses this information to track the Web interactions of individual
users and to limit the frequency with which the user is shown a particular
advertisement. Some currently available Internet browser programs allow users to
modify their browser settings to disable this information at any time or to
prevent this information from being stored on their hard drives. In addition,
some Internet commentators, privacy advocates and governmental bodies have
suggested limiting or eliminating the use of this information. The effectiveness
of our technology and the success of our business model would be severely
limited by any reduction or limitation in the use of user information.
    
 
   
THE INTERNET MAY NOT BE ACCEPTED AS AN ADVERTISING MEDIUM, WHICH WOULD ADVERSELY
  AFFECT OUR BUSINESS
    
 
   
        If the Internet advertising market fails to develop or develops more
slowly than expected, or if our services do not achieve market acceptance, our
business and quarterly and annual results of operations would be materially and
adversely affected. The Internet advertising market has only recently begun to
develop and is evolving rapidly. This market may not prove to be viable or, if
it becomes viable, may not continue to grow. Our future growth largely depends
on the continued growth in Internet advertising generally, and on the
willingness of advertisers, ad agencies, Web sites and ad rep firms to outsource
their Internet advertising and direct marketing needs. Our growth also depends
on our ability to market our ad management and delivery services in a
cost-effective manner to a sufficiently large number of customers.
    
 
        Demand and market acceptance for Internet advertising services are
uncertain. Companies doing business on the Internet, including us, 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. Entities that have historically relied upon traditional
media for advertising may be reluctant to adopt new ways of conducting business,
exchanging information and advertising products and services on the Internet.
 
   
        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, and our

operations, would be materially and adversely affected by Internet users'
widespread adoption of these software programs.
    
 
   
THE INTERNET INFRASTRUCTURE MAY NOT BE VIABLE OR CONTINUE TO GROW, WHICH WOULD
  ADVERSELY AFFECT OUR BUSINESS
    
 
   
        Our success is largely dependent upon the viability and continued growth
of the Internet infrastructure. We depend on the Internet infrastructure to
provide the performance, capacity and reliability needed to support the growth
of the Internet and Internet advertising. If the Internet infrastructure fails
to support the growth of the Internet, our business and quarterly and annual
results of operations, would be adversely affected. There are regularly failures
in the Internet network infrastructure, and there are likely to be more in the
future, which may have the effect of undermining advertisers' confidence in the
Internet as a viable commercial medium. Particularly, if the Internet continues
to experience an increase in users, an increase in frequency of use or an
increase in the capacity requirements of users, we cannot assure you that the
Internet infrastructure will be able to support the demands placed upon it. Any
actual or perceived degradation in the performance of the Internet as a whole
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 generally.
Even if the required infrastructure, standards, protocols and complementary
products, services and facilities are developed, we may be required to spend
heavily to adapt our solutions to emerging technologies.
    
 
   
OUR MANAGEMENT TEAM MAY NOT WORK TOGETHER SUCCESSFULLY, AND WE MAY BE UNABLE TO
  ATTRACT AND RETAIN KEY PERSONNEL WE NEED TO SUCCEED
    
 
   
        Our future success depends to a significant extent 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 a new Executive Vice President, Development and Operations, a new Vice
President, Sales and Business Development and a new Vice President, Marketing.
The loss of the services of any of our senior level management, or other key
employees, would likely have a material adverse effect on our business and
quarterly and annual results of operations. 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 running our company. Any dissent among executive officers could
adversely affect our ability to make strategic decisions quickly in a rapidly
changing market.
    
 
   
        Our future success also depends on our ability to attract, retain and
motivate highly skilled employees. Competition for employees in our industry is
intense. We may be unable to retain our key employees or to attract, assimilate
and retain other highly qualified employees in the future. We have in the past
experienced, and we expect in the future to continue to experience, difficulty
in hiring and retaining highly skilled employees with appropriate
qualifications.
    
 
   
ANY INABILITY TO MANAGE OUR GROWTH WOULD ADVERSELY AFFECT 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. If we are not able to manage our internal growth
effectively to keep pace with the expansion of the Internet advertising market
or our competitors' growth, our business and quarterly and annual results of
operations would be materially and
    
 
                                       11
<PAGE>
   
adversely affected. 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. Please see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" for detailed information on our internal growth.
    
 
   
ANY INABILITY TO PROTECT OUR TECHNOLOGY WOULD ADVERSELY AFFECT OUR BUSINESS
    
 
   
        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 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.
    
 
   
        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 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. In addition, we
cannot assure you that these business partners will take the same steps we have
taken to prevent misappropriation of our solutions or technologies.
    
 
THIRD PARTIES MAY ASSERT INFRINGEMENT CLAIMS AGAINST US OR OUR CUSTOMERS
 
   
        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 or 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
    
 
                                       12
<PAGE>
   
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.
    
 
OUR CONTRACTUAL RELATIONSHIP WITH AMERICA ONLINE MAY ADVERSELY AFFECT OUR
  BUSINESS
 
   
        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, which would have a material and
adverse effect on our business and quarterly and annual results of operations.
Please see "Certain Transactions" for detailed information on our relationship
with America Online.
    
 
GOVERNMENT REGULATION OF THE INTERNET MAY ADVERSELY AFFECT OUR BUSINESS
 
   
        Any 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, which could have a material and adverse effect on our
business and quarterly and annual results of operations. The applicability to
the Internet of existing laws governing issues such as property ownership, libel
and personal privacy is uncertain. In addition, 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. Finally, the
global nature of the Internet could subject us to the laws of foreign
jurisdictions in an unpredictable manner.
    
 
   
        The potential imposition of liability upon us for our content or
services could require us to implement measures to reduce our exposure to this
liability, which might require us to expend substantial resources or to
discontinue service offerings. While we carry general liability insurance, this
insurance may not be adequate to compensate us in the event we become liable for
our services. Any liability in excess of our insurance could have a material and
adverse effect on our business and quarterly and annual results of operations.
    
 
   
        In addition, the growing use of the Internet has burdened the existing
telecommunications infrastructure and has caused interruptions in telephone
service. Telephone carriers have petitioned the government to regulate the
Internet and impose usage fees on Internet service providers. Any regulations of
this type could increase the costs of using the Internet and impede its growth,
which could in turn decrease the demand for our services.

POTENTIAL YEAR 2000 RISKS MAY ADVERSELY AFFECT OUR BUSINESS
 
   
        Beginning in the year 2000, the date fields coded in computer systems
and software products will need to accept four-digit entries in order to
distinguish between 21st century and 20th century dates. There is significant
uncertainty in the software industry regarding the potential effects associated
with Year 2000 compliance issues. To address these concerns, we have reviewed
internally developed software included in our ad management and delivery
systems. Further, we are working with our external suppliers and service
providers with respect to both third-party applications in our ad management and
delivery systems 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. Based on these efforts, we
believe we have no significant Year 2000 issues within our systems or services.
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. Further,
we have not deferred any of our ongoing development efforts to address Year 2000
issues, and do not anticipate any material payments to vendors to remediate Year
2000 problems. However, there can be no assurance that unanticipated costs
associated with any Year 2000 compliance will not exceed our present
expectations and have a material adverse effect on our business and quarterly
and annual results of operations.
    
 
   
        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
heavily 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 business,
results of operations and financial condition. Further, the purchasing patterns
of advertisers and ad 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 business
and quarterly and annual results of 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 FUTURE CAPITAL TO EXECUTE OUR BUSINESS OBJECTIVES
    
 
   
        If we cannot raise funds, when needed, on acceptable terms, we may not
be able to develop or enhance our services, take advantage of future
opportunities or respond to competitive pressures or unanticipated requirements,
which could materially and adversely affect our business and quarterly and
annual results of operations. 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. Expenses may include leasing
real estate, purchasing equipment and hiring network, administrative and
customer support personnel. 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.
We expect the net proceeds from this offering, our current cash and cash
equivalents and borrowings from lease financings to meet our working capital and
capital expenditure needs for at least the next twelve months. After that, 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. Further, if
we issue equity securities, stockholders may experience additional dilution or
the holders of the new equity securities may have rights, preferences or
privileges senior to those of existing holders of common stock.
    
 
                                       14

THE PRICE OF OUR COMMON STOCK IS LIKELY TO BE VOLATILE AND SUBJECT TO WIDE
  FLUCTUATIONS
    
 
   
        The market prices of the securities of Internet-related companies have
been especially volatile and these securities may be overvalued. 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 be materially and
adversely affected. 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 be materially and adversely affected 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 securities class action 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
    
 
   
        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 which could depress the market price of your shares. Although the
assumed initial public offering price was determined based on a number of
factors, the initial public offering price may significantly vary from the
market price after the offering.
    
 
   
PROVISIONS IN OUR CHARTER DOCUMENTS MAY DETER ACQUISITION BIDS FOR ADFORCE
    
 
   
        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
 
   
        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 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 AFFECT OUR STOCK PRICE
 
   
        If our stockholders sell substantial amounts of our common stock in the
public market following this offering, the market price of our common stock
could decline. Based on shares outstanding as of March 31, 1999, upon completion
of this offering we will have outstanding 19,169,429 shares of common stock,
assuming no exercise of the underwriters' over-allotment option. Of these
shares, 5,207,368 will be eligible for immediate sale in the public market. 180
days from the date of this prospectus, an additional 13,962,061 shares will be
eligible for sale in the public market. These share numbers do not include
3,575,445 shares subject to outstanding options and warrants and 3,361,938
shares reserved for future issuance under our stock plans as of March 31, 1999.

                                USE OF PROCEEDS
 
   
        We estimate that the net proceeds to us from the sale of the 4,500,000
shares of common stock offered by us will be $44,935,000, at an assumed initial
public offering price of $11.00 per share and after deducting the estimated
underwriting discounts and commissions and offering expenses. If the
underwriters' over-allotment option is exercised in full, we estimate that our
net proceeds will be $51,840,250.
    
 
   
        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."
    
 
                                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.

two shares of common stock upon the closing of this offering and (3) the pro
forma capitalization as adjusted to reflect the receipt of the net proceeds from
the sale of the 4,500,000 shares of common stock offered by AdForce at an
assumed initial public offering price of $11.00 per share and after deducting
the estimated underwriting discounts and commissions and offering expenses.

                                    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 an assumed initial public offering price of $11.00 per
share and after deducting the estimated underwriting discounts and commissions
and offering expenses, the pro forma net tangible book value of AdForce as of
March 31, 1999 would have been approximately $50.5 million, or $2.63 per share.
This represents an immediate increase in pro forma net tangible book value of
$2.25 per share to existing stockholders and an immediate dilution of $8.37 per
share to new investors purchasing shares at the initial public offering price.
The following table illustrates the per share dilution:

        The foregoing 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. To the extent that any of these options or warrants are exercised, there
will be further dilution to new public investors. Please see "Capitalization,"

                 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 Fortune City, 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, 24/7 Media and Netcom 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 over the long term. In the second
quarter of 1999, our second data center will be made operational, potentially
increasing our costs to deliver each ad in the near term. 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
    
 
                                       21
<PAGE>
   
our system. 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
February 1998. As of March 31, 1999, we had recorded aggregate deferred stock
compensation of $7.8 million. This deferred stock compensation is being
amortized over the vesting periods of the stock options. AdForce recognized a
total of $1.0 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 $2.7
million, $1.9 million, $900,000 and $200,000 for the remaining nine months of
1999 and for 2000, 2001 and 2002.
    
 
   
        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 $2.6 million. The
purchase price was primarily allocated to intangible assets, including purchased
technology of $1.7 million and personnel-related assets of $740,000, 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 $849,000 related to this purchase were recognized during
1998, and further amortization charges of $926,000, $587,000 and $46,000 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, $15.0 million for year ended December 31, 1998, and $4.8 million for
the three months ended March 31, 1999. As of March 31, 1999, our accumulated
deficit was $29.0 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
    
 
                                       24
<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 96% in the first
quarter of 1998 to negative 79% in the second quarter of 1998 to negative 14% in
the third quarter of 1998 to positive 19% in the fourth quarter of 1998 and to
positive 33% 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 continue to
decline over the long-term, although on a quarterly basis these costs may
fluctuate. In April 1999, we opened our second data center in order 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 18% in 1998 and
positive 33% 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 in order 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
    
 
                                       25
<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
respective 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.

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
    
 
                                       27

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 certain
demographic data. 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 certain
costs related to internal-use software once certain 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
    
 
                                       28
<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 in order 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 in order 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. In
certain cases, we have warranted to 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 business and 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 business and quarterly and
annual results of operations. 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 business and quarterly and annual
results of operations.

        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
    
 
                                       30
<PAGE>
   
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.
    
 
                                       31
<PAGE>
   
        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 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

    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, thereby 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 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 in order 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 to achieve our objective 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. In order 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
 
                                       34
<PAGE>
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 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:
    
 
   
        [icon]    MEDIA PLANNING. Reflecting the media planner's workflow,
                  AdForce for Advertisers organizes the 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.
    
 
        [icon]    CAMPAIGN SCHEDULING. Advertisers, ad agencies, Web sites and
                  ad rep firms can use a Java client application to create and
                  schedule ad campaigns over the Internet. An ad campaign wizard
                  guides users as they 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.
 
   
        [icon]    INVENTORY MANAGEMENT. Our automated Inventory Management
                  System gives Web sites and ad rep firms 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.
    
 
                                       35
<PAGE>
   
        [icon]    TARGETING. Serving ads from a central data center, we can
                  employ more comprehensive targeting 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.
    
 
   
        [icon]    AD DELIVERY. Our ad delivery system delivers ads quickly,
                  consistently, on schedule and on target. 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.
    
 
   
        [icon]    TRANSACTIONS. Our transactions feature records user activities
                  such as click-throughs, requesting 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.
    
 
   
        [icon]    REPORTING. We use detailed information accumulated from every
                  ad delivered and consolidated across 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.
    
 
        [icon]    AUDITING AND ACCOUNTING. We provide audited statements that
                  detail the number of ads delivered, 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.
 
   
        [icon]    ANALYSIS. Advertisers, ad agencies, Web sites and ad rep firms
                  can use the information stored in 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.

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 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
    
 
                                       37
<PAGE>
   
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 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.

KEY CUSTOMERS
 
   
        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 1998, 24/7 Media and GeoCities accounted for 40% and 16% 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 Extremely Competitive Market for Internet Ad Management and
Delivery Services" 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 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 "Certain
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 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.

officer and has served as a member of AdForce's board of directors from its
inception to December 1996 and again since November 1998. Since May 1998, Mr.

        Our board of directors is currently comprised of five directors and has
two vacancies. Directors are elected by the stockholders at each annual meeting
of stockholders and serve for one year or 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 Mr. Berger has been designated as a Class III director. 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 AdForce's internal accounting procedures and consults
with and reviews the results and scope of the audit and other services provided
by AdForce's 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 AdForce's 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 as to 25% of the shares on the anniversary of the date
of grant and as to 2.08% of the shares every 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.
    
 
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.

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.
    
 
   
        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 certain changes in control of AdForce, vesting
will accelerate as to 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) Potential realizable values are net of the exercise price but before any
    payment of taxes, and are based on the assumption that our common stock
    appreciates at the annual compounded rate shown from the date of grant until
    the expiration of the ten-year term. The 5% and 10% assumed annual rates of
    stock price appreciation are mandated by the rules of the Securities and
    Exchange Commission and do not represent our estimate or projection of
    future common stock prices.
    
 
   
(3) These options terminated in November 1998 upon termination of Mr.
    Steelberg's employment. See "--Employment Agreements and Severance

        Mr. Rao was hired in January 1999 and was granted a ten-year option to
purchase 360,000 shares of our common stock at an exercise price of $1.50 per
share. The option vests over three years at the rate of 33% of the shares
subject to the option on the first anniversary of the vesting start date
specified in the stock option agreement and 2.79% every month after that date.
Mr. Cravens was hired in January 1999 and was granted a ten-year option to
purchase 175,000 shares of our common stock at an exercise price of $1.50 per
share. The option vests 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. Mr. Glaves was
hired in January 1999 and was granted a ten-year option to purchase 175,000
shares of our common stock at an exercise price of $1.50 per share. The option
vests over four years at the rate of 12 1/2% of the shares subject to the option
on the six month anniversary of the vesting start date specified in the stock
option agreement and 2.08% every month after that date. Mr. Jackson was hired in
July 1998 and was granted a ten-year option to purchase 180,000 shares of our
common stock at an exercise price of $1.50 per share. The option vests at the
same rate as those of Mr. Cravens.

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 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 bona fide 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 certain 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 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
    
 
                                       50
<PAGE>
   
purchase period. Our purchase plan will terminate in February 2009, unless
earlier terminated pursuant to its terms. 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
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
direct the 401(k) plan's trustee to invest their accounts in authorized
investment alternatives.
    
 
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 Stock 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.
Mr. Berger vested as to 25% of the option shares on that date and began to vest
monthly after that date as to 2.08% of the shares for so long as he remains in
service with AdForce. 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.
    
 
        AdForce and Mr. Rao are parties to a letter agreement dated December 11,
1998 governing his employment with AdForce. Under the agreement, AdForce agreed
to pay Mr. Rao an annual salary of $215,000 and a performance bonus of $50,000,
and to grant Mr. Rao an option to purchase 360,000 shares
 
                                       51
<PAGE>
of common stock at a fair market value exercise price. AdForce's repurchase
right will begin to lapse and Mr. Rao will vest as to 33% of the shares subject
to the option after one year of service; the balance of the shares will vest
monthly over the next 24 months of 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.
    
 
        AdForce and Mr. Cravens are parties to a letter agreement dated January
21, 1999 governing his employment with AdForce. Under the agreement, AdForce
agreed to pay Mr. Cravens an annual salary of $185,000 and a $25,000 signing
bonus, and granted Mr. Cravens an immediately exercisable option to purchase
175,000 shares of AdForce's common stock at a fair market value exercise price.
AdForce's repurchase right will lapse and Mr. Cravens will vest as to 25% of the
shares subject to the option 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 a fair market value
exercise price. AdForce's repurchase right will lapse and Mr. Glaves will vest
as to 12.5% of the shares subject to the option after six months of service; the
balance of the shares will vest monthly over the next 42 months of service.
    
 
   
        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 a
fair market value exercise price. AdForce's repurchase right will lapse and Mr.
Jackson will vest as to 25% of the shares subject to the option 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.
    
 
   
        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;
 
                                       52
<PAGE>
        - 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 certain 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, we intend to enter into indemnity agreements, prior to
the completion of this offering, 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 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.

                              CERTAIN 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.

stock in exchange for the cancellation of $997,500 owed by us and the
termination of a warrant to purchase 123,400 shares of common stock. In
addition, Washington Holdings, a Nevada limited partnership, purchased 402,964
shares of Series A preferred stock in exchange for the cancellation of $506,000
of indebtedness and the repayment of $119,000 owed by us. We also used $305,000
to repay indebtedness to Aurelius, Ltd., a British Virgin Island corporation.
Dirk Wray, one of our directors, is a representative of Aurelius, Ltd.
    
 
   
        Also in December 1996, we sold 2,054,636 shares of Series B preferred
stock to six investors. Hummer Winblad Venture Partners II L.P., Hummer Winblad

purchased 957,542, 33,912 and 5,984 shares of Series B preferred stock,
respectively, for an aggregate purchase price of $1,251,785, or $1.255 per
share. The Hummer Winblad group of funds is one of our principal stockholders,
and Mark P. Gorenberg, one of our directors, is a partner at 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 preferred stock
for a purchase price of $1,251,785, or $1.255 per share. 21st Century Internet
Fund, L.P. is one of our principal stockholders, and J. Neil Weintraut, one of
our directors, is a founder and managing member of 21st Century Internet
Managing Partners, LLC, which is the general partner of this fund.
    
 
   
        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 certain agreements with
certain of its founders. Pursuant to such agreements, AdForce repurchased 7,886
    
 
                                       54
<PAGE>
   
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 stock in the event of a liquidation event resulting in proceeds
to holders of 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
"Management--Employment Agreements and Severance Agreements."

        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

    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. In the services agreement, 2CAN Media agreed to use our Internet
advertising administration system as its exclusive advertising serving
technology. As of December 31, 1998, the agreement has generated $260,000 in net
revenue for AdForce.
    
 
   
        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 certain 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 certain percentages. 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
    
 
                                       56
<PAGE>
   
America Online advertising and privacy policies. If we receive access to the
demographic data, we will pay America Online quarterly fees based on the greater
of a certain percentage of the consideration charged by us for targeted
advertising or a certain percentage of the incremental revenue charged by us for
the targeting feature. The fees we pay will total at least $10.0 million for the
first three years after we are granted access to the demographic data. 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 in the event 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.
    
 
   
        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.

                             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 any such 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
    
 
                                       60
<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 pursuant to 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 Amended and Restated
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
certain 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.

<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."
    
 
TRANSFER AGENT AND REGISTRAR
 
   
        The transfer agent and registrar for our common stock is ChaseMellon
Shareholder Services, LLC.

                        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
    
 
                                       63
<PAGE>
   
sell those shares without complying with the manner of sale, public information,
volume limitation or notice provisions of Rule 144.
    
 
    RULE 701
 
   
        In general, under Rule 701 of the Securities Act, any of our employees,
officers, directors, consultants or advisors who purchased shares from us in
connection with a compensatory stock or option plan or other written agreement
is eligible to resell those shares 90 days after the effective date of this
offering in reliance on Rule 144, but without compliance with certain
restrictions, including the holding period contained in Rule 144. However, all
shares issued pursuant to Rule 701 are subject to lock-up agreements and will
only become eligible for sale at the earlier of the expiration of the 180-day
lock-up agreements or obtaining the prior written consent of Hambrecht & Quist
LLC or the other representatives of the underwriters more than 90 days after
this offering.
    
 
    REGISTRATION RIGHTS
 
   
        Upon completion of this offering, the holders of 10,532,696 shares of
our common stock and rights to acquire common stock, or their transferees, will
be entitled to rights to register their shares under the Securities Act. See
"Description of Capital Stock--Registration Rights." After registration, these
shares could be sold without restriction under the Securities Act.
    
 
    STOCK OPTIONS
 
   
        Promptly following this offering, we will file a registration statement
under the Securities Act covering all shares of common stock subject to
outstanding options or reserved for issuance under our 1999 plan, our directors
plan or our stock purchase plan. Based on the number of shares subject to
options outstanding at March 31, 1999 and currently reserved for issuance under
these plans, this registration statement would cover approximately 5,642,697
shares. The registration statement will automatically become effective upon
filing. Accordingly, shares registered under the registration statement will,
subject to Rule 144 volume limitations applicable to our affiliates, be
available for sale in the open market immediately after the 180-day lock-up
agreements expire.

</TABLE>
    
 
   
        The underwriting agreement provides that the obligations of the
underwriters are subject to certain conditions, including the absence of any
material adverse change in AdForce's business and the receipt of certain
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 certain dealers at that price less a concession
not in excess of $     per share. The underwriters may allow and such dealers
may reallow a concession not in excess of $     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 thereof 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.
 
   
        We have agreed to indemnify the underwriters against certain
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 otherwise dispose of any shares of common
    
 
                                       65
<PAGE>
   
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 otherwise 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.
See "Certain Transactions" and "Principal 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

        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 will be
negotiated by AdForce and the underwriters. Among the factors to be considered
in determining the initial public offering price will be 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. The estimated initial public
offering price range shown on the cover of this preliminary prospectus is
subject to change as a result of changes in these factors.
    
 
   
        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.

               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 $24,176,000 and $29,019,000 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 $849,000 and $1,087,000,
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

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

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 and options to
purchase 48,056 shares of common stock with an aggregate fair value of $220,000
based on the deemed fair value of the Company's common stock at the time of
issuance, (iii) $113,000 of debt and (iv) $162,000 in acquisition costs in a
transaction that was accounted for as a purchase.
    
 
        The purchase consideration was allocated to the acquired assets and
assumed liabilities based on fair values as follows (in thousands):

        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 $1,669,000 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.

        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

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. 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.
 
   
        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. To date, AdForce has not had access to the
demographic data and there is no final implementation schedule or procedure for
such access.
    
 
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.

6.  COMMITMENTS (CONTINUED)
   
        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.

        In February 1999, AdForce executed a lease-line agreement for a total of
$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

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.
 
    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,

8.  STOCKHOLDERS' EQUITY (CONTINUED)
        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.
    
 
    WARRANTS
 
        In association with certain transactions, AdForce issued warrants to
third parties for the purchase of AdForce's common stock and convertible
preferred stock. The warrants that remained outstanding at December 31, 1998
were as follows:

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 data
vendor were exercised 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.
 
   
        AdForce has determined the value of all warrants granted to third
parties, excluding the value attributable to equity investments, to be
approximately $2,274,000 and will record 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.
    
 
    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.
 
        In connection with the acquisition by AdForce of StarPoint as described
in Note 2, AdForce assumed all options outstanding under the StarPoint Software,
Inc. 1996 Stock Plan ("StarPoint Plan"). These options vest over a 48-month
period with 9/48 of the underlying shares vesting after the employee had
completed nine months of continuous employment at AdForce and 1/48 of the
underlying shares vesting each month thereafter.

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 $1,052,000 and
$1,088,000 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.
    
 
        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

was $3.70 and $6.31, respectively.

    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.

8.  STOCKHOLDERS' EQUITY (CONTINUED)
 
   
    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
 
        Due to operating losses and the inability to recognize the benefits
therefrom, 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.
 
        Significant components of AdForce's deferred tax assets and liabilities
are as follows (in thousands):

10. INCOME TAXES (CONTINUED)
        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 (UNAUDITED)
    
 
        In February 1999, the Board of Directors approved the reincorporation in
the state of Delaware as AdForce, Inc. subject to stockholder approval.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
AdForce, Inc.
 
        We have audited the accompanying balance sheet of StarPoint Software,
Inc. as of May 31, 1997, and the related statements of operations, shareholders'
equity (net capital deficiency), and cash flows for the period from August 8,
1996 (inception) through May 31, 1997. 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 audit.
 
        We conducted our audit 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 audit provides 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 StarPoint, Software,
Inc. at May 31, 1997, and the results of its operations and its cash flows for
the period from August 8, 1996 (inception) through May 31, 1997, in conformity
with generally accepted accounting principles.

                         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.

payments under the noncancelable lease agreement for the year ended May 31, 1998
was $37,125.
 
        Rent expense was approximately $60,500 for the period from August 8,
1996 (inception) through May 31, 1997.

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

48-month period and have a maximum term of ten years.

        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.

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

Stock, Series D Preferred Stock and Series E Preferred Stock are as set forth
below.

          1.   DIVIDEND PROVISIONS.  The holders of outstanding Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock and Series E 



<PAGE>

Preferred Stock shall be entitled to receive in any fiscal year, when and as 
declared by the Board of Directors, out of any assets at the time legally 
available therefor, dividends in cash at the rate of $0.20, $0.20, $0.38, 
$1.10 and $1.10 per share per annum, respectively (appropriately adjusted to 
reflect any subsequent stock dividends, combinations, splits, 
recapitalizations and the like with respect to the affected series of 
Preferred Stock), before any cash dividend is paid on Common Stock.  Such 
dividend or distribution may be payable annually or otherwise as the Board of 
Directors may from time to time determine.  Dividends or distributions (other 
than dividends payable solely in shares of Common Stock) may be declared and 
paid upon shares of Common Stock in any fiscal year of the corporation only 
if dividends shall have been paid on or declared and set apart upon all 
outstanding shares of Series A Preferred Stock, Series B Preferred Stock, 
Series C Preferred Stock, Series D Preferred Stock and Series E Preferred 
Stock at such annual rate; and no dividends shall be paid to holders of 
shares of Common Stock unless at the same time equivalent dividends in the 
same amount per share of Common Stock issuable upon conversion thereof are 
paid to holders of outstanding shares of Series A Preferred Stock, Series B 
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and 
Series E Preferred Stock in excess of such annual rate in any fiscal year.  
No dividends shall be paid to holders of any series of Preferred Stock unless 
at the same time equivalent dividends are paid to holders of all series of 
Preferred Stock.  The right to such dividends on outstanding shares of Series 
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series 
D Preferred Stock and Series E Preferred Stock shall not be cumulative and no 
right shall accrue to holders of shares of Series A Preferred Stock, Series B 
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock or Series 
E Preferred Stock by reason of the fact that dividends on said shares are not 
declared in any prior year, nor shall any undeclared or unpaid dividend bear 
or accrue interest.  The holders of the outstanding Series A Preferred Stock, 
Series B Preferred Stock and Series C Preferred Stock can waive any dividend 
preference that such holders may be entitled to receive under this Section 1 
upon the affirmative vote or written consent of the holders of at least 
seventy-five percent (75%) of the shares of Series A Preferred Stock, Series 
B Preferred Stock and Series C Preferred Stock then outstanding, voting or 
consenting as a single class on an as-if-converted basis.  The holders of the 
outstanding Series D Preferred Stock can waive any dividend preference that 
such holders may be entitled to receive under this Section 1 upon the 
affirmative vote or written consent of the holders of a majority of the 
shares of Series D Preferred Stock then outstanding, voting or consenting as 
a separate series. The holders of the outstanding Series E Preferred Stock 
can waive any dividend preference that such holders may be entitled to 
receive under this Section 1 upon the affirmative vote or written consent of 
the holders of a majority of the shares of Series E Preferred Stock then 
outstanding, voting or consenting as a separate series.

       2. LIQUIDATION PREFERENCE.

               (a)  In the event of any liquidation, dissolution or winding up
of this corporation, either voluntary or involuntary, subject to the rights of
any series of Preferred Stock that may from time to time come into existence,
the holders of Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock and Series E Preferred Stock shall be entitled to receive, prior
and in preference to any distribution of any of the assets and funds of this
corporation to the holders of Series A Preferred Stock or Common Stock by reason
of their ownership thereof, an amount per share equal to (i) $2.51 for each
outstanding share of Series B 


                                   2
<PAGE>

Preferred Stock (the "Original Series B Issue Price") (such price per share 
to be appropriately adjusted to reflect any subsequent stock dividends, 
combinations, splits, recapitalizations and the like with respect to the 
Series B Preferred Stock) plus any declared but unpaid dividends on such 
share, (ii) $4.73 for each outstanding share of Series C Preferred Stock (the 
"Original Series C Issue Price") (such price per share to be appropriately 
adjusted to reflect any subsequent stock dividends, combinations, splits, 
recapitalizations and the like with respect to the Series C Preferred Stock) 
plus any declared but unpaid dividends on such share, (iii) $13.73 for each 
outstanding share of Series D Preferred Stock (the "Original Series D Issue 
Price") (such price per share to be appropriately adjusted to reflect any 
subsequent stock dividends, combinations, splits, recapitalizations and the 
like with respect to the Series D Preferred Stock) plus any declared but 
unpaid dividends on such share, and (iv) $13.73 for each outstanding share of 
Series E Preferred Stock (the "Original Series E Issue Price") (such price 
per share to be appropriately adjusted to reflect any subsequent stock 
dividends, combinations, splits, recapitalizations and the like with respect 
to the Series E Preferred Stock) plus any declared but unpaid dividends on 
such share.  If upon the occurrence of such event, the assets and funds thus 
distributed among the holders of the Series B Preferred Stock, Series C 
Preferred Stock, Series D Preferred Stock and Series E Preferred Stock shall 
be insufficient to permit the payment to such holders of the full aforesaid 
preferential amounts, then, subject to the rights of series of Preferred 
Stock that may from time to time come into existence, the entire assets and 
funds of this corporation legally available for distribution shall be 
distributed ratably among the holders of the Series B Preferred Stock, Series 
C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock in 
proportion to the preferential amount each such holder is otherwise entitled 
to receive. 

               (b)  After the distributions required by subsection 2(a) above
have been paid, if assets and funds remain in the corporation that are legally
available for distribution, the holders of the Series B Preferred Stock, Series
C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock shall
receive from the remaining assets of the corporation available for distribution
to shareholders 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
shareholders of the corporation, assuming the conversion to Common Stock of all
shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock, Series D Preferred Stock and Series E Preferred Stock.

               (c)  After the distributions required by subsections 2(a) and
2(b) above have been paid, if assets and funds remain in the corporation that
are legally available for distribution to shareholders, the Series A Preferred
Stock shall receive an amount per share equal to the sum of (i) $2.51 for each
outstanding share of Series A Preferred Stock (the "Original Series A Issue
Price") and (ii) an amount equal to any declared but unpaid dividends on such
share.  If upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Series A Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then the entire assets and funds of the corporation
legally available for distribution shall be distributed ratably among the
holders of the Series A Preferred Stock in proportion to the amount of such
stock owned by each such holder.

               (d)  Thereafter, if assets and funds remain in the corporation
that are legally available for distribution to shareholders, the holders of
Series A Preferred Stock and 


                                   3
<PAGE>

Common Stock shall receive all of the remaining assets of the corporation pro 
rata based on the number of shares of Common Stock held by each such holder 
(assuming conversion to Common Stock of all such Series A Preferred Stock).

               (e)  For purposes of this Section 2, (i) any acquisition of this
corporation by means of merger or other form of corporate reorganization in
which the shareholders of this corporation immediately before the closing of
such transaction do not, by virtue of shares issued in the transaction, own a
majority of the outstanding shares of the surviving corporation or (ii) a sale
of all or substantially all of the assets of this corporation shall, unless the
holders of (A) seventy-five percent (75%) of the shares of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock then outstanding,
voting or consenting in writing as a single class on an as-if-converted to
Common Stock basis, (B) a majority of the shares of Series D Preferred Stock
then outstanding, voting or consenting in writing as a separate series, and (C)
a majority of the shares of Series E Preferred Stock then outstanding, voting or
consenting in writing as a separate series, elect in writing otherwise, be
deemed to be treated as a liquidation, dissolution or winding up of this
corporation and shall entitle the holders of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
Preferred Stock and Common Stock to receive at the closing cash, securities or
other property as specified in subsections 2(a), 2(b), 2(c) and 2(d) above.

               (f)  In any of such events, if the consideration received by the
corporation is other than cash, its value will be deemed its fair market value. 
Any securities shall be valued as follows:

                    (i)  Securities not subject to investment letter or other
similar restrictions on free marketability:

                         (A)  If traded on a securities exchange or the Nasdaq
National Market, the value shall be deemed to be the average of the closing
prices of the securities on such exchange over the 30-day period ending three
(3) days prior to the closing;

                         (B)  If actively traded over-the-counter other than on
the Nasdaq National Market, the value shall be deemed to be the average of the
closing bid prices over the 30-day period ending three (3) days prior to the
closing; and

                         (C)  If there is no active public market, the value
shall be the fair market value thereof, as mutually determined by this
corporation and the holders of at least seventy-five percent (75%) of the voting
power of all then outstanding shares of Preferred Stock.

                    (ii) The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value as determined above in subsection 2(f)(i)(A), (B) or (C) to reflect the
approximate fair market value thereof, as mutually determined by this
corporation and the 


                                   4
<PAGE>

holders of at least a majority of the voting power of all then outstanding 
shares of such Preferred Stock.

               
               (g)  In the event the requirements of subsection 2(e) are not 
complied with, the corporation shall forthwith either:

                    (i)  cause such closing to be postponed until such time as
the requirements of this Section 2 have been complied with, or

                    (ii) cancel such transaction, in which event the rights,
preferences, privileges, and restrictions of the holders of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
Stock and Series E Preferred Stock shall revert to and be the same as such
rights, preferences, privileges and restrictions existing immediately prior to
the date of the first notice referred to in subsection 2(h) hereof.

               (h)  The corporation shall give each holder of record of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock and Series E Preferred Stock written notice of such a
subsection 2(e) transaction not later than twenty (20) days prior to the
shareholders' meeting called to approve such transaction, or twenty (20) days
prior to the closing of such transaction, whichever is earlier.  The first of
such notices shall describe the material terms and conditions of the impending
transaction and the provisions of subsection 2(e), and the corporation shall
thereafter give such holders prompt notice of any material changes and shall
provide such other information to such shareholders regarding such transactions
as they may reasonably request.  If, in connection with a subsection 2(e)
transaction, the holders of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock or Series E Preferred Stock
elect to convert their shares into shares of Common Stock pursuant to subsection
3(a) below, such conversion will be conditioned upon the closing of the
subsection 2(e) transaction, unless otherwise designated in writing by the
holder of such Preferred Stock, in which event the person(s) entitled to receive
the Common Stock issuable upon such conversion of the Preferred Stock shall not
be deemed to have converted such Preferred Stock until immediately prior to the
closing of such subsection 2(e) transaction.  The transaction shall in no event
take place sooner than twenty (20) days after the corporation has given the
first notice provided for herein or sooner than ten (10) days after the
corporation has given notice of any material changes provided for herein;
provided, however, that such periods may be shortened upon the written consent
of the holders of a majority of the shares of Preferred Stock then outstanding,
voting or consenting as a single class on an as-if-converted to Common Stock
basis.

          3.   CONVERSION.  The holders of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E
Preferred Stock shall have conversion rights as follows (the "Conversion
Rights"):

               (a)  RIGHT TO CONVERT.  Each share of Series A, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such 

                                   5
<PAGE>

share at the office of this corporation or any transfer agent for such stock, 
into such number of fully paid and nonassessable shares of Common Stock as is 
determined by dividing the Original Series A Issue Price, the Original Series 
B Issue Price, the Original Series C Issue Price, the Original Series D Issue 
Price or the Original Series E Issue Price by the Conversion Price applicable 
to such share, determined as hereafter provided, in effect on the date the 
certificate is surrendered for conversion.  The initial Conversion Price per 
share for shares of Series A Preferred Stock, Series B Preferred Stock, 
Series C Preferred Stock, Series D Preferred Stock and Series E Preferred 
Stock shall be one-half of the Original Series A Issue Price, one-half of the 
Original Series B Issue Price, one-half of the Original Series C Issue Price, 
one-half of the Original Series D Issue Price and one-half of the Original 
Series E Issue Price, respectively; provided, however, that the Conversion 
Prices for Series A Preferred Stock, Series B Preferred Stock, Series C 
Preferred Stock, Series D Preferred Stock and Series E Preferred Stock shall 
be subject to adjustment as set forth in subsection 3(d).

               (b)  AUTOMATIC CONVERSION.
               
                    (i)   Each share of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock shall automatically be converted
into shares of Common Stock at the Conversion Price at the time in effect for
such series of Preferred Stock immediately upon the earlier of (i) this
corporation's sale of its Common Stock pursuant to a registration statement
under the Securities Act of 1933, as amended, which results in aggregate gross
cash proceeds to this corporation in excess of $15,000,000 and the public
offering price of which is not less than $6.275 per share of Common Stock
(appropriately adjusted to reflect subsequent stock dividends, combinations,
splits, recapitalizations or the like) or (ii) the date specified by written
consent or agreement of the holders of at least seventy-five percent (75%) of
the shares of Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock then outstanding, voting or consenting as a single class on an
as-if-converted basis.
                    
                    (ii)  Each share of Series D Preferred Stock shall
automatically be converted into shares of Common Stock at the Conversion Price
at the time in effect for such series of Preferred Stock immediately upon the
earlier of (i) this corporation's sale, in a firm commitment underwritten public
offering, of its Common Stock pursuant to a registration statement under the
Securities Act of 1933, as amended, which results in aggregate gross cash
proceeds to this corporation of $20,000,000 or greater and the public offering
price of which is not less than the Qualifying Price Per Share, or (ii) the date
specified by written consent or agreement of the holders of at least a majority
of the shares of Series D Preferred Stock then outstanding, voting or consenting
as a separate series.  As used herein, the "Qualifying Price Per Share" shall
mean the quotient of $125,000,000 divided by the number of shares of the
corporation's Common Stock outstanding immediately prior to such sale, assuming
conversion of all Preferred Stock and other convertible securities then
outstanding and the exercise of all warrants, options and other rights then
outstanding to purchase Common Stock or other securities convertible into Common
Stock of this corporation.
                    
                    (iii) Each share of Series E Preferred Stock shall
automatically be converted into shares of Common Stock at the Conversion Price
at the time in effect for such 

                                   6
<PAGE>


series of Preferred Stock immediately upon the earlier of (i) this 
corporation's sale, in a firm commitment underwritten public offering, of its 
Common Stock pursuant to a registration statement under the Securities Act of 
1933, as amended, which results in aggregate net cash proceeds to this 
corporation of $20,000,000 or greater and the public offering price of which 
is not less than the Qualifying Price Per Share, or (ii) the date specified 
by written consent or agreement of the holders of at least a majority of the 
shares of Series E Preferred Stock then outstanding, voting or consenting as 
a separate series.
                    
               (c)  MECHANICS OF CONVERSION.  Before any holder of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock or Series E Preferred Stock shall be entitled to convert the
same into shares of Common Stock, such holder shall surrender the certificate or
certificates therefor, duly endorsed, at the office of this corporation or of
any transfer agent for the Preferred Stock, and shall give written notice by
mail, postage prepaid, to this corporation at its principal corporate office, of
the election to convert the same and shall state therein the name or names in
which the certificate or certificates for shares of Common Stock are to be
issued.  This corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Preferred Stock, or to the nominee or
nominees of such holder, a certificate or certificates for the number of shares
of Common Stock to which such holder shall be entitled as aforesaid.  Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of such surrender of the shares of Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date.  If the
conversion is in connection with an underwritten offer of securities registered
pursuant to the Securities Act of 1933, as amended, the conversion will be
conditioned upon the closing with the underwriter of the sale of securities
pursuant to such offering, unless otherwise designated in writing by the holders
of such Preferred Stock, in which event the person(s) entitled to receive the
Common Stock issuable upon such conversion of the Preferred Stock shall not be
deemed to have converted such Preferred Stock until immediately prior to the
closing of such sale of securities.

               (d)  CONVERSION PRICE ADJUSTMENTS OF PREFERRED STOCK.  The
Conversion Price of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, Series D Preferred Stock and Series E Preferred Stock shall be
subject to adjustment from time to time as follows:

                    (i)   (A) If the corporation, at any time or from time to
time after the date that this Certificate of Incorporation is filed with the
Secretary of State of the State of Delaware (the "Filing Date"), shall issue any
Additional Stock (as defined below) without consideration or for a consideration
per Common Stock equivalent share less than the Conversion Price for a given
series in effect immediately prior to the issuance of such Additional Stock,
then, except as provided in subsection 3(d)(v) below, the Conversion Price for
such series in effect immediately prior to each such issuance shall forthwith be
adjusted to a price determined by multiplying such Conversion Price by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to such issuance plus the number of shares of
Common Stock that the aggregate consideration received by the corporation 


                                   7
<PAGE>

for such issuance would purchase at such Conversion Price; and the 
denominator of which shall be the number of shares of Common Stock 
outstanding immediately prior to such issuance plus the number of shares of 
such Additional Stock.  For purposes of this subsection 3(d), the number of 
shares of Common Stock outstanding at a given time shall be deemed to be the 
number of shares of Common Stock that are then issued and outstanding plus 
the number of shares of Common Stock then issuable upon exercise of all then 
outstanding warrants and options to purchase Common Stock or securities 
convertible into Common Stock plus the number of shares of Common Stock then 
issuable upon conversion of such convertible securities and all other 
convertible securities then outstanding.

                          (B) No adjustment of the Conversion Price for any
series of Preferred Stock shall be made in an amount less than one cent per
share, provided that any adjustments which are not required to be made by reason
of this sentence shall be carried forward and shall be either taken into account
in any subsequent adjustment made prior to 3 years from the date of the event
giving rise to the adjustment being carried forward, or shall be made at the end
of 3 years from the date of the event giving rise to the adjustment being
carried forward.  Except to the limited extent provided for in subsections
3(d)(i)(E)(3) and 3(d)(i)(E)(4), no adjustment of such Conversion Price pursuant
to this subsection 3(d)(i)(B) shall have the effect of increasing the Conversion
Price above the Conversion Price in effect immediately prior to such adjustment.
                          
                          (C) In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
before deducting any reasonable discounts, commissions or other expenses
allowed, paid or incurred by this corporation for any underwriting or otherwise
in connection with the issuance and sale thereof.

                          (D) In the case of the issuance of Common Stock for
a consideration in whole or in part other than cash, the consideration other
than cash shall be deemed to be the fair value thereof as reasonably determined
by the Board of Directors in its good faith judgment irrespective of any
accounting treatment.

                          (E) In the case of the issuance, whether before, on
or after the Filing Date, of options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options to purchase or rights to subscribe for such convertible
or exchangeable securities (which are not excluded from the definition of
Additional Stock), the following provisions shall apply:

                              1.    The aggregate maximum number of shares of
Common Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subsections 3(d)(i)(C) and 3(d)(i)(D)), if
any, received by the corporation upon the issuance of such options or rights
plus the minimum purchase price provided in such options or rights (without
taking into account potential anti-dilution adjustments) for the Common Stock
covered thereby.

                                   8
<PAGE>


                              2.    The aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange for any such
convertible or exchangeable securities or upon the exercise of options to
purchase or rights to subscribe for such convertible or exchangeable securities
and subsequent conversion or exchange thereof shall be deemed to have been
issued at the time such securities were issued or such options or rights were
issued and for a consideration equal to the consideration, if any, received by
the corporation for any such securities and related options or rights (excluding
any cash received on account of accrued interest or accrued dividends), plus the
additional consideration, if any, to be received by the corporation upon the
conversion or exchange of such securities or the exercise of any related options
or rights (the consideration in each case to be determined in the manner
provided in subsections 3(d)(i)(C) and 3(d)(i)(D)).

                              3.    In the event of any change in the number of
shares of Common Stock deliverable or any increase in the consideration payable
to this corporation upon exercise of such options or rights or upon conversion
of or in exchange for such convertible or exchangeable securities, including,
but not limited to, a change resulting from the antidilution provisions thereof,
the Conversion Price of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock or Series E Preferred Stock
obtained with respect to the adjustment that was made upon the issuance of such
options, rights or securities, and any subsequent adjustments based thereon,
shall be recomputed to reflect such change, but no further adjustment shall be
made for the actual issuance of Common Stock or any payment of such
consideration upon the exercise of any such options or rights or the conversion
or exchange of such securities.

                              4.    Upon the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock or Series E Preferred
Stock obtained with respect to the adjustment which was made upon the issuance
of such options, rights or securities or options or rights related to such
securities, and any subsequent adjustments based thereon, shall be recomputed to
reflect the issuance of only the number of shares of Common Stock actually
issued upon the exercise of such options or rights, upon the conversion or
exchange of such securities or upon the exercise of the options or rights
related to such securities.  Upon the expiration of any such options or rights,
the termination of any such rights to convert or exchange or the expiration of
any options or rights related to such convertible or exchangeable securities,
only the number of shares of Common Stock actually issued upon the exercise of
such options or rights, upon the conversion or exchange of such securities or
upon the exercise of the options or rights related to such securities shall
continue to be deemed to be issued.

                              5.    The number of shares of Common Stock deemed
issued and the consideration deemed paid therefor pursuant to subsections
3(d)(i)(E)(1) and 3(d)(i)(E)(2) shall be appropriately adjusted to reflect any
change, termination or expiration of the type described in either
subsection 3(d)(i)(E)(3) or 3(d)(i)(E)(4).

                                   9
<PAGE>

                    (ii)  "Additional Stock" shall mean any shares of Common
Stock issued (or deemed to have been issued pursuant to subsection 3(d)(i)(E))
by this corporation after the Filing Date other than shares of Common Stock
issued or issuable:
     
                          (A) pursuant to a transaction described in
subsection 3(d)(iii) hereof;

                          (B) to officers, directors, employees and
consultants of this corporation directly or pursuant to a stock option plan or
restricted stock plan approved by the Board of Directors of this corporation or
pursuant to the StarPoint Software, Inc. 1996 Stock Plan;

                          (C) upon conversion of the Preferred Stock;

                          (D) pursuant to warrants issued to banks or
equipment lessors (provided, however, that this subsection 3(d)(ii)(D) shall not
be applicable to any calculation of a Conversion Price adjustment of the Series
D Preferred Stock or Series E Preferred Stock);

                          (E) in connection with business combinations or
corporate partnering agreements approved by the Board of Directors, provided
that at the time of any such issuance, the aggregate of such issuance and
similar issuances in the preceding twelve month period do not exceed 2% of the
then outstanding Common Stock of the corporation (assuming full conversion and
exercise of all convertible and exercisable securities) (provided, however, that
this subsection 3(d)(ii)(E) shall not be applicable to any calculation of a
Conversion Price adjustment of the Series D Preferred Stock or Series E
Preferred Stock); or

                          (F) in connection with the merger of Imgis, Inc., a
California corporation, with and into the corporation.
                          
                    (iii) In the event the corporation should at any time or
from time to time after the Purchase Date fix a record date for the effectuation
of a split or subdivision of the outstanding shares of Common Stock or the
determination of holders of Common Stock entitled to receive a dividend or other
distribution to receive a distribution payable in additional shares of Common
Stock or other securities or rights convertible into, or entitling the holder
thereof to receive directly or indirectly, additional shares of Common Stock
(hereinafter referred to as "Common Stock Equivalents") without payment of any
consideration by such holder for the additional shares of Common Stock or the
Common Stock Equivalents (including the additional shares of Common Stock
issuable upon conversion or exercise thereof), then, as of such record date (or
the date of such dividend distribution, split or subdivision if no record date
is fixed), the Conversion Price of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred
Stock shall be appropriately decreased so that the number of shares of Common
Stock issuable on conversion of each share of such series 

                                   10
<PAGE>


shall be increased in proportion to such increase of outstanding shares 
determined in accordance with subsection 3(d)(i)(E).

                    (iv)  If the number of shares of Common Stock outstanding
at any time after the Purchase Date is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date of such
combination, the Conversion Price for Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E
Preferred Stock shall be appropriately increased so that the number of shares of
Common Stock issuable on conversion of each share of such series shall be
decreased in proportion to such decrease of outstanding shares.

               (e)  OTHER DISTRIBUTIONS.  In the event this corporation shall
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by this corporation or other persons, assets (excluding cash
dividends) or options or rights not referred to in subsection 3(d)(iii), then,
in each such case for the purpose of this subsection 3(e), the holders of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock,
Series D Preferred Stock and Series E Preferred Stock shall be entitled to a
proportionate share of any such distribution as though they were the holders of
the number of shares of Common Stock of the corporation into which their shares
of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock,
Series D Preferred Stock and Series E Preferred Stock are convertible as of the
record date fixed for the determination of the holders of Common Stock of the
corporation entitled to receive such distribution.

               (f)  RECAPITALIZATIONS.  If at any time or from time to time
there shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 3) provision shall be made so that the holders of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock and Series E Preferred Stock shall thereafter be entitled to
receive upon conversion of the Preferred Stock the number of shares of stock or
other securities or property of the corporation or otherwise, to which a holder
of Common Stock deliverable upon conversion would have been entitled on such
recapitalization.  In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 3 with respect to the rights of
the holders of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, Series D Preferred Stock and Series E Preferred Stock after the
recapitalization to the end that the provisions of this Section 3 (including
adjustment of the Conversion Price then in effect and the number of shares
purchasable upon conversion of Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred
Stock) shall be applicable after that event as nearly equivalent as may be
practicable.

               (g)  NO IMPAIRMENT.  This corporation will not, by amendment of
its Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by this
corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 3 and in the taking of all such action as may
be necessary or


                                       11

<PAGE>

appropriate in order to protect the Conversion Rights of the
holders of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, Series D Preferred Stock and Series E Preferred Stock.

               (h)  NO FRACTIONAL SHARES AND CERTIFICATE AS TO ADJUSTMENTS.

                    (i)   No fractional shares shall be issued upon conversion
of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock,
Series D Preferred Stock or Series E Preferred Stock and the number of shares of
Common Stock to be issued shall be rounded down to the nearest whole share. 
Whether or not fractional shares are issuable upon such conversion shall be
determined on the basis of the total number of shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
Stock or Series E Preferred Stock the holder is at the time converting into
Common Stock and the number of shares of Common Stock issuable upon such
aggregate conversion.

                    (ii)  Upon the occurrence of each adjustment or
readjustment of any Conversion Price of Series A Preferred Stock, Series B

purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to

any other securities or property, or to receive any other right, this
corporation shall mail to each holder of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E
Preferred Stock at least 10 days prior to the date specified therein, a notice
specifying the date on which any such record is to be taken for the purpose of
such dividend, distribution or right, and the amount and character of such

               (j)  RESERVATION OF STOCK ISSUABLE UPON CONVERSION.  This
corporation shall at all times reserve and keep available out of its authorized

                                   12
<PAGE>

Stock solely for the purpose of effecting the conversion of the shares of 
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, 
Series D Preferred Stock and Series E Preferred Stock such number of its 
shares of Common Stock as shall from time to time be sufficient to effect the 
conversion of all outstanding shares of Series A Preferred Stock, Series B 
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and 
Series E Preferred Stock; and if at any time the number of authorized but 
unissued shares of Common Stock shall not be sufficient to effect the 
conversion of all the then outstanding shares of Series A Preferred Stock, 
Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock 
and Series E Preferred Stock, in addition to such other remedies as remedies 
as shall be available to the holder of such Preferred Stock, this corporation 
will take such corporate action as may, in the opinion of its counsel, be 
necessary to increase its authorized but unissued shares of Common Stock to 
such number of shares as shall be sufficient for such purposes.

               (k)  NOTICES.  Any notice required by the provisions of this
Section 3 to be given to the holders of shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and
Series E Preferred Stock shall be deemed effectively given upon personal
delivery to the holder to be notified, or upon deposit with the United States
Post Office, or with a nationally recognized overnight courier specifying next
day delivery with written verification of receipt, postage prepaid, and
addressed to each holder of record at his address appearing on the books of this
corporation.

          4.   VOTING RIGHTS.

               (a)  The authorized number of directors of the corporation shall
be seven (7).  At each election of directors of this corporation, the holders of
Series B Preferred Stock shall be entitled, voting as a separate series, to
elect two (2) directors of the corporation.  The holders of the outstanding
Series C Preferred Stock shall be entitled, voting as a separate series, to
elect two (2) directors of the corporation.  For so long as AOL and its
affiliates collectively hold at least 364,166 shares of Series E Preferred Stock
(appropriately adjusted to reflect any subsequent stock dividends, combinations,
splits, recapitalizations and the like with respect to the Series E Preferred
Stock), the holders of the outstanding Series E Preferred Stock, at their
option, shall be entitled, voting as a separate series, to elect one (1)
director of the corporation.  The holders of outstanding Common Stock, and the
holders of outstanding Series D Preferred Stock, voting on an as-if converted to
Common Stock basis, shall be entitled, voting together as a class, to elect the
remaining number of directors of this corporation that are not elected by the
holders of Series B Preferred Stock, Series C Preferred Stock and Series E
Preferred Stock at each annual election of directors.  In the case of any
vacancy (other than a vacancy caused by removal) in the office of a director
occurring among the directors elected by the holders of a class or series of
stock pursuant to this Section, the remaining directors so elected by that class
or series may by affirmative vote of a majority thereof (or the remaining
director so elected if there be but one, or if there are no such directors
remaining, by the affirmative vote of the holders of a majority of the shares of
that class or series), elect a successor or successors to hold office for the
unexpired term of the director or directors whose place or places shall be
vacant.  Any director who shall have been elected by the holders of a class or
series of stock or by any directors so elected as provided in the immediately
preceding sentence 

                                   13
<PAGE>


hereof may be removed during the aforesaid term of office, either with or 
without cause, by, and only by, the affirmative vote of the holders of the 
shares of the class or series of stock entitled to elect such director or 
directors, given either at a special meeting of such shareholders duly called 
for that purpose or pursuant to a written consent of shareholders, and any 
vacancy thereby created may be filled by the holders of that class or series 
of stock represented at the meeting or pursuant to unanimous written consent.

               (b)  Except as explicitly provided for in Section 4(a) above, the
holder of each share of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock
shall have the right to one vote for each share of Common Stock into which such
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock,
Series D Preferred Stock or Series E Preferred Stock, respectively, could then
be converted (with any fractional share determined on an aggregate conversion
basis being rounded to the nearest whole share), and with respect to such vote,
such holder shall have full voting rights and powers equal to the voting rights
and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any shareholders' meeting in
accordance with the by-laws of this corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote.

          5.   PROTECTIVE PROVISIONS.  

               (a)  So long as at least 625,000 shares of Series B Preferred
Stock, Series C Preferred Stock, Series D Preferred Stock and/or Series E
Preferred Stock (appropriately adjusted to reflect any subsequent stock
dividends, combinations, splits, recapitalizations and the like with respect to
such series of Preferred Stock) remain outstanding, this corporation shall not
without first obtaining the approval (by vote or written consent, as provided by
law) of the holders of a majority of the voting power of the then outstanding
shares of Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
Stock and Series E Preferred Stock, voting together as a single class on an as-
if-converted to Common Stock basis:

                    (i)   sell, convey, or otherwise dispose of or encumber all
or substantially all of its property or business or merge into or consolidate
with any other corporation (other than a wholly owned subsidiary corporation) or
effect any transaction or series of related transactions in which more than 50%
of the voting power of the corporation is disposed of;

                    (ii)  authorize the payment of dividends on or the
repurchase of Common Stock; provided, however, that this restriction shall not
apply to the repurchase of shares of Common Stock from employees, officers,
directors, consultants or other persons performing services for this corporation
or any subsidiary pursuant to agreements under which this corporation has the
option to repurchase such shares at cost or at cost upon the occurrence of
certain events, such as the termination of employment;

                                   14
<PAGE>

                    (iii) change the authorized number of directors of the
corporation; or
     
                    (iv)  authorize the issuance of any stock, or any other
securities convertible into or exercisable or exchangeable for equity
securities, of the corporation to any person or group of affiliated persons if,
immediately following such issuance, such person or group of affiliated persons
would hold a greater Pro Rata Share (as defined below) of the corporation's then
outstanding Common Stock than would then be held collectively by AOL and its
affiliates.  For purposes hereof, "Pro Rata Share" means a fraction, the
numerator of which is the number of shares of Common Stock of the corporation
issued and held, or issuable upon conversion of Preferred Stock of the
corporation then held, by the holder and the denominator of which is the total
number of shares of Common Stock of the corporation then outstanding assuming
full conversion and exercise of all convertible or exercisable securities then
outstanding.

               (b)  So long as at least 625,000 shares of Series B Preferred 
Stock and/or Series C Preferred Stock (appropriately adjusted to reflect any 
subsequent stock dividends, combinations, splits, recapitalizations and the 
like with respect to such series of Preferred Stock) remain outstanding, this 
corporation shall not without first obtaining the approval (by vote or 
written consent, as provided by law) of the holders of at least seventy-five 
percent (75%) of the voting power of the then outstanding shares of Series B 
Preferred Stock and Series C Preferred Stock, voting together as a single 
class on an as-if-converted to Common Stock basis:

                    (i)   create any new class or series of stock or any other
securities convertible into equity securities of the corporation (A) having a
preference over, or being on a parity with, Series B Preferred Stock or Series C
Preferred Stock with respect to voting, dividends or distributions upon
liquidation, or (B) having rights similar to any of the rights of Series B
Preferred Stock or Series C Preferred Stock under this Section 5;

                    (ii)  amend, waive or repeal any provision of, or add any
provision to, these Articles of Incorporation if such action would adversely
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, Series B Preferred Stock or Series C
Preferred Stock;

                    (iii) increase or decrease (other than by conversion) the
authorized number of shares of Series B Preferred Stock or Series C Preferred
Stock; or

                    (iv)  merge with or consolidate with any other corporation
where such merger would result in an adverse change in the rights, preferences
or privileges of Series B Preferred Stock or Series C Preferred Stock that would
otherwise require consent under subsection 5(b)(ii) above.
     
               (c)  So long as any shares of Series D Preferred Stock remain
outstanding, this corporation shall not, without first obtaining the approval
(by vote or written 

                                   15
<PAGE>

consent, as provided by law) of the holders of a majority of the then 
outstanding shares of Series D Preferred Stock, voting as a separate series:
     
                    (i)   create any new class or series of stock or any other
securities convertible into or exercisable or exchangeable for equity securities
of the corporation (A) having a preference over Series D Preferred Stock with
respect to voting, dividends or distributions upon liquidation, or (B) having
rights similar to any of the rights of Series D Preferred Stock under this
Section 5;
     
                    (ii)  amend, waive or repeal any provision of, or add any
provision to, these Articles of Incorporation if such action would (A) adversely
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, Series D Preferred Stock, or (B) alter
or change the provisions governing automatic conversion of the Series D
Preferred Stock set forth in subsection 3(b) above;
     
                    (iii) increase or decrease (other than by conversion) the
authorized number of shares of Series D Preferred Stock, or authorize the
issuance of any shares of Series D Preferred Stock, or any other securities
convertible into or exercisable or exchangeable for Series D Preferred Stock, to
any person who, as of the Filing Date, does not hold of record any shares of
Series D Preferred Stock; or
     
                    (iv)  redeem or repurchase any of this corporation's Common
Stock or Preferred Stock, other than repurchases of securities held by
directors, employees or consultants of the corporation not to exceed $100,000
per transaction and $400,000 in the aggregate, and other than redemptions or
repurchases at the original purchase price of such securities.
     
               (d)  So long as any shares of Series E Preferred Stock remain
outstanding, this corporation shall not, without first obtaining the approval
(by vote or written consent, as provided by law) of the holders of a majority of
the then outstanding shares of Series E Preferred Stock, voting as a separate
series:
     
                    (i)   create any new class or series of stock, or any other
securities convertible into or exercisable or exchangeable for equity
securities, of the corporation (A) having a preference over Series E Preferred
Stock with respect to voting, dividends or distributions upon liquidation, or
(B) having rights similar to any of the rights of Series E Preferred Stock under
this Section 5;
     
                    (ii)  amend, waive or repeal any provision of, or add any
provision to, these Articles of Incorporation if such action would (A) adversely
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, Series E Preferred Stock, or (B) alter
or change the provisions governing automatic conversion of the Series E
Preferred Stock set forth in subsection 3(b) above;

                                   16
<PAGE>


                    (iii) increase or decrease (other than by conversion) the
authorized number of shares of Series E Preferred Stock, or authorize the
issuance of any shares of Series E Preferred Stock, or any other securities
convertible into or exercisable or exchangeable for Series E Preferred Stock, to
any person other than AOL; or
     
                    (iv)  redeem or repurchase any of this corporation's Common
Stock or Preferred Stock, other than repurchases of securities held by
directors, employees or consultants of the corporation not to exceed $100,000
per transaction and $400,000 in the aggregate, and other than redemptions or
repurchases at the original purchase price of such securities.
     
          6.   REDEMPTION.  The Preferred Stock is not redeemable.

          7.   STATUS OF CONVERTED STOCK.  In the event any shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock or Series E Preferred Stock shall be converted pursuant to
Section 3 hereof, the shares so converted shall be canceled and shall not be
issuable by the corporation, and the Articles of Incorporation of this
corporation shall be appropriately amended to effect the corresponding reduction
in the corporation's authorized capital stock.

          8.   REPURCHASE OF SHARES.  In connection with repurchases by this
corporation of its Common Stock pursuant to its agreements with certain of the
holders thereof providing for such repurchases in the event of the termination
of the status of such holder as an employee, director or consultant to the
corporation, each holder of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock
shall be deemed to have consented to distributions made by the corporation with

          1.   DIVIDEND RIGHTS.  Subject to the prior rights of holders of all
classes of stock at the time outstanding having prior rights as to dividends,

available therefor, such dividends as may be declared from time to time by the
Board of Directors.

                                     ARTICLE V

     The Board of Directors of the corporation shall have the power to adopt,
amend or repeal the Bylaws of the corporation.

                                     ARTICLE VI

     For the management of the business and for the conduct of the affairs of
the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:
     
     (A)  The conduct of the affairs of the corporation shall be managed under
the direction of its Board of Directors.  The number of directors shall be fixed
from time to time exclusively by resolution of the Board of Directors.

     (B)  Notwithstanding the foregoing provision of this Article VI, each
director shall hold office until such director's successor is elected and
qualified, or until such director's earlier death, resignation or removal.  No
decrease in the authorized number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

     (C)  Subject to the rights of the holders of any series of Preferred Stock,
any vacancy occurring in the Board of Directors for any cause, and any newly
created directorship resulting from any increase in the authorized number of
directors, shall, unless (i) the Board of Directors determines by resolution
that any such vacancies or newly created directorships shall be filled by the
stockholders, or (ii) as otherwise provided by law, be filled only by the
affirmative vote of a majority of the directors then in office, although less
than a quorum, or by a sole remaining director, and not by the stockholders. 
Any director elected in accordance with the preceding sentence shall hold office
for the remainder of the full term of the director for which the vacancy was
created or occurred.

     (D)  Subject to the rights of the holders of any series of Preferred Stock,
any director or the entire Board of Directors may be removed, with or without
cause, by the holders of at least a majority of the shares then entitled to vote
at an election of directors; PROVIDED, HOWEVER, that a director may not be
removed without cause if the votes cast against removal of the director, or not
consenting in writing to the removal, would be sufficient to elect the director
if voted cumulatively (without regard to whether shares may otherwise be voted
cumulatively) at an election at which the same total number of votes were cast
(or, if the action is taken by written consent, all shares entitled to vote were
voted) and either the number of directors elected at the most recent annual
meeting of stockholders, or if greater, the number of directors for whom removal
is being sought, were then being elected.

     (E)  Subject to the rights of the holders of any series of Preferred Stock
to elect additional directors under specified circumstances, following the
closing of the corporation's 


                                   18
<PAGE>


initial public offering pursuant to an effective registration statement under 
the Securities Act of 1933, as amended, covering the offer and sale of Common 
Stock to the public (the "INITIAL PUBLIC OFFERING"), the directors shall be 
divided, with respect to the time for which they severally hold office, into 
three classes designated as Class I, Class II and Class III, respectively.  
Directors shall be assigned to each class in accordance with a resolution or 
resolutions adopted by the Board of Directors, with the number of directors 
in each class to be divided as equally as reasonably possible.  The term of 
office of the Class I directors shall expire at the corporation's first 
annual meeting of stockholders following the closing of the Initial Public 
Offering, the term of office of the Class II directors shall expire at the 
corporation's second annual meeting of stockholders following the closing of 
the Initial Public Offering, and the term of office of the Class III 
directors shall expire at the corporation's third annual meeting of 
stockholders following the closing of the Initial Public Offering.  At each 
annual meeting of stockholders commencing with the first annual meeting of 
stockholders following the closing of the Initial Public Offering, directors 
elected to succeed those directors of the class whose terms then expire shall 
be elected for a term of office to expire at the third succeeding annual 
meeting of stockholders after their election.

     (F)  Election of directors need not be by written ballot unless the Bylaws
of the corporation shall so provide.

     (G)  Following the closing of the Initial Public Offering, no action shall
be taken by the stockholders of the corporation except at an annual or special
meeting of stockholders called in accordance with the Bylaws of the corporation,
and no action shall be taken by the stockholders by written consent.

     (H)  Advance notice of stockholder nominations for the election of
directors of the corporation and of business to be brought by stockholders
before any meeting of stockholders of the corporation shall be given in the
manner provided in the Bylaws of the corporation.  Business transacted at
special meetings of stockholders shall be confined to the purpose or purposes
stated in the notice of meeting.

                                    ARTICLE VII

     To the fullest extent permitted by law, no director of the corporation
shall be personally liable for monetary damages for breach of fiduciary duty as
a director.  Without limiting the effect of the preceding sentence, if the
Delaware General Corporation Law is hereafter amended to authorize the further
elimination or limitation of the liability of a director, then the liability of
a director of the corporation shall be eliminated or limited to the fullest
extent permitted by the Delaware General Corporation Law, as so amended.

     Neither any amendment nor repeal of this Article VII, nor the adoption of
any provision of this Certificate of Incorporation inconsistent with this
Article VII, shall eliminate, reduce or otherwise adversely affect any
limitation on the personal liability of a director of the corporation existing
at the time of such amendment, repeal or adoption of such an inconsistent
provision.

by the law of the State of Delaware, to provide for the issuance of the shares
of Preferred Stock in one or more series, and, by filing a Certificate of
Designation pursuant to the applicable law of the State of Delaware, to
establish from time to time the number of shares to be included in each such
series, to fix the designation, powers, preferences and rights of the shares of
each such series and any qualifications, limitations or restrictions thereof,
and to increase or decrease the number of shares of any such series (but not
below the number of shares of such series then outstanding).  The number of
authorized shares of Preferred Stock may also be increased or decreased (but not
below the number of shares thereof then outstanding) by the affirmative vote of
the holders of a majority of the stock of the corporation entitled to vote,
unless a vote of any other holders is required pursuant to a Certificate or
Certificates establishing a series of Preferred Stock.

     Except as otherwise expressly provided in any Certificate of Designation
designating any series of Preferred Stock pursuant to the foregoing provisions
of this Article IV, any new series 


<PAGE>


of Preferred Stock may be designated, fixed and determined as provided herein 
by the Board of Directors without approval of the holders of Common Stock or 
the holders of Preferred Stock, or any series thereof, and any such new 
series may have powers, preferences and rights, including, without 
limitation, voting rights, dividend rights, liquidation rights, redemption 
rights and conversion rights, senior to, junior to or pari passu with the 
rights of the Common Stock, the Preferred Stock, or any future class or 
series of Preferred Stock or Common Stock.
     
                                          
                                     ARTICLE V

     The Board of Directors of the corporation shall have the power to adopt,
amend or repeal the Bylaws of the corporation.

                                     ARTICLE VI

     For the management of the business and for the conduct of the affairs of
the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:
     
     (A)  The conduct of the affairs of the corporation shall be managed under
the direction of its Board of Directors.  The number of directors shall be fixed
from time to time exclusively by resolution of the Board of Directors.

     (B)  Notwithstanding the foregoing provision of this Article VI, each
director shall hold office until such director's successor is elected and
qualified, or until such director's earlier death, resignation or removal.  No
decrease in the authorized number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

     (C)  Subject to the rights of the holders of any series of Preferred Stock,
any vacancy occurring in the Board of Directors for any cause, and any newly
created directorship resulting from any increase in the authorized number of
directors, shall, unless (i) the Board of Directors determines by resolution
that any such vacancies or newly created directorships shall be filled by the
stockholders, or (ii) as otherwise provided by law, be filled only by the
affirmative vote of a majority of the directors then in office, although less
than a quorum, or by a sole remaining director, and not by the stockholders. 
Any director elected in accordance with the preceding sentence shall hold office
for the remainder of the full term of the director for which the vacancy was
created or occurred.

     (D)  Subject to the rights of the holders of any series of Preferred Stock,
any director or the entire Board of Directors may be removed, only with cause,
by the holders of a majority of the shares then entitled to vote at an election
of directors; PROVIDED HOWEVER, that a director may not be removed without 
casuse if the votes cast against removal of the director would be sufficient 
to elect the director if voted cumulative (without regard to whether shares 
may otherwise be voted cumulatively) at an election at which the same total 
number of votes


                                     2
<PAGE>


were cast and either the number of directors elected at the most recent 
annual meeting of stockholders, or if greater, the number of directors for 
whom removal is being sought, were then being elected.

     (E)  Subject to the rights of the holders of any series of Preferred 
Stock to elect additional directors under specified circumstances, following 
the closing of the corporation's initial public offering pursuant to an 
effective registration statement under the Securities Act of 1933, as 
amended, covering the offer and sale of Common Stock to the public (the 
"INITIAL PUBLIC OFFERING"), the directors shall be divided, with respect to 
the time for which they severally hold office, into three classes designated 
as Class I, Class II and Class III, respectively.  Directors shall be 
assigned to each class in accordance with a resolution or resolutions adopted 
by the Board of Directors, with the number of directors in each class to be 
divided as equally as possible. The term of office of the Class I directors 
shall expire at the corporation's first annual meeting of stockholders 
following the closing of the Initial Public Offering, the term of office of 
the Class II directors shall expire at the corporation's second annual 
meeting of stockholders following the closing of the Initial Public Offering, 
and the term of office of the Class III directors shall expire at the 
corporation's third annual meeting of stockholders following the closing of 
the Initial Public Offering.  At each annual meeting of stockholders 
commencing with the first annual meeting of stockholders following the 
closing of the Initial Public Offering, directors elected to succeed those 
directors of the class whose terms then expire shall be elected for a term of 
office to expire at the third succeeding annual meeting of stockholders after 
their election.

     (F)  Election of directors need not be by written ballot unless the Bylaws
of the corporation shall so provide.

     (G)  Following the closing of the Initial Public Offering, no action shall
be taken by the stockholders of the corporation except at an annual or special
meeting of stockholders called in accordance with the Bylaws of the corporation,
and no action shall be taken by the stockholders by written consent.

     (H)  Advance notice of stockholder nominations for the election of
directors of the corporation and of business to be brought by stockholders
before any meeting of stockholders of the corporation shall be given in the
manner provided in the Bylaws of the corporation.  Business transacted at
special meetings of stockholders shall be confined to the purpose or purposes
stated in the notice of meeting.

                                    ARTICLE VII

     To the fullest extent permitted by law, no director of the corporation
shall be personally liable for monetary damages for breach of fiduciary duty as
a director.  Without limiting the effect of the preceding sentence, if the
Delaware General Corporation Law is hereafter amended to authorize the further
elimination or limitation of the liability of a director, then the liability of
a director of the corporation shall be eliminated or limited to the fullest
extent permitted by the Delaware General Corporation Law, as so amended.


                                     3
<PAGE>

     Neither any amendment nor repeal of this Article VII, nor the adoption of
any provision of this Certificate of Incorporation inconsistent with this
Article VII, shall eliminate, reduce or otherwise adversely affect any
limitation on the personal liability of a director of the corporation existing
at the time of such amendment, repeal or adoption of such an inconsistent
provision.

any other person or persons.  If a special meeting of stockholders is called at
the request of any person or persons OTHER THAN by a majority of the members of
the Board of Directors, then such person or persons shall request such meeting
by delivering a written request to call such meeting to each member of the Board
of Directors, and the Board of Directors shall then determine the time, date and
place of such special meeting, which shall be held not more than one hundred
twenty (120) nor less than thirty-five (35) days after the written request to
call such special meeting was delivered to each member of the Board of
Directors.

     SECTION 1.3:   NOTICE OF MEETINGS.  Written notice of all meetings of
stockholders shall be given stating the place, date and time of the meeting and,
in the case of a special meeting, the purpose or purposes for which the meeting
is called.  Unless otherwise required by applicable law or the Certificate of
Incorporation of the Corporation, such notice shall be given not less than ten
(10) nor more than sixty (60) days before the date of the meeting to each
stockholder of record entitled to vote at such meeting.

     SECTION 1.4:   ADJOURNMENTS.  Any meeting of stockholders may adjourn from
time to time to reconvene at the same or another place, and notice need not be
given of any such adjourned meeting if the time, date and place thereof are
announced at the meeting at which the adjournment is taken; PROVIDED, HOWEVER,
that if the adjournment is for more than thirty (30) days, or if after the
adjournment a new record date is fixed for the adjourned meeting, then a 


<PAGE>

notice of the adjourned meeting shall be given to each stockholder of record 
entitled to vote at the meeting.  At the adjourned meeting the Corporation 
may transact any business that might have been transacted at the original 
meeting.

     SECTION 1.5:   QUORUM.  At each meeting of stockholders the holders of a 
majority of the shares of stock entitled to vote at the meeting, present in 
person or represented by proxy, shall constitute a quorum for the transaction 
of business, except if otherwise required by applicable law.  If a quorum 
shall fail to attend any meeting, the chairperson of the meeting or the 
holders of a majority of the shares entitled to vote who are present, in 
person or by proxy, at the meeting may adjourn the meeting.  Shares of the 
Corporation's stock belonging to the Corporation (or to another corporation, 
if a majority of the shares entitled to vote in the election of directors of 
such other corporation are held, directly or indirectly, by the Corporation), 
shall neither be entitled to vote nor be counted for quorum purposes; 
PROVIDED, HOWEVER, that the foregoing shall not limit the right of the 
Corporation or any other corporation to vote any shares of the Corporation's 
stock held by it in a fiduciary capacity. 

     SECTION 1.6:   ORGANIZATION.  Meetings of stockholders shall be presided 
over by such person as the Board of Directors may designate, or, in the 
absence of such a person, the Chairperson of the Board of Directors, or, in 
the absence of such person, the President of the Corporation, or, in the 
absence of such person, such person as may be chosen by the holders of a 
majority of the shares entitled to vote who are present, in person or by 
proxy, at the meeting.  Such person shall be chairperson of the meeting and, 
subject to Section 1.11 hereof, shall determine the order of business and the 
procedure at the meeting, including such regulation of the manner of voting 
and the conduct of discussion as seems to him or her to be in order.  The 
Secretary of the Corporation shall act as secretary of the meeting, but in 
such person's absence the chairperson of the meeting may appoint any person 
to act as secretary of the meeting.

     SECTION 1.7:    VOTING; PROXIES.  Unless otherwise provided by law or 
the Certificate of Incorporation, and subject to the provisions of Section 
1.8 of these Bylaws, each stockholder shall be entitled to one (1) vote for 
each share of stock held by such stockholder.  Each stockholder entitled to 
vote at a meeting of stockholders, or to express consent or dissent to 
corporate action in writing without a meeting, may authorize another person 
or persons to act for such stockholder by proxy.  Such a proxy may be 
prepared, transmitted and delivered in any manner permitted by applicable 
law.  Voting at meetings of stockholders need not be by written ballot unless 
such is demanded at the meeting before voting begins by a stockholder or 
stockholders holding shares representing at least one percent (1%) of the 
votes entitled to vote at such meeting, or by such stockholder's or 
stockholders' proxy; PROVIDED, HOWEVER, that an election of directors shall 
be by written ballot if demand is so made by any stockholder at the meeting 
before voting begins.  If a vote is to be taken by written ballot, then each 
such ballot shall state the name of the stockholder or proxy voting and such 
other information as the chairperson of the meeting deems appropriate. 
Directors shall be elected by a plurality of the votes of the shares present 
in person or represented by proxy at the meeting and entitled to vote on the 
election of directors.  Unless otherwise provided by applicable law, the 
Certificate of Incorporation or these Bylaws, every matter other than the 
election of directors shall be decided by the affirmative vote of the holders 
of a majority of the shares of stock entitled to vote thereon 


                                   -2-
<PAGE>

that are present in person or represented by proxy at the meeting and are 
voted for or against the matter.  

     SECTION 1.8:   FIXING DATE FOR DETERMINATION OF STOCKHOLDERS OF RECORD.  
In order that the Corporation may determine the stockholders entitled to 
notice of or to vote at any meeting of stockholders or any adjournment 
thereof, or to express consent to corporate action in writing without a 
meeting, or entitled to receive payment of any dividend or other distribution 
or allotment of any rights, or entitled to exercise any rights in respect of 
any change, conversion or exchange of stock or for the purpose of any other 
lawful action, the Board of Directors may fix, in advance, a record date, 
which shall not precede the date upon which the resolution fixing the record 
date is adopted by the Board of Directors and which shall not be more than 
sixty (60) nor less than ten (10) days before the date of such meeting, nor 
more than sixty (60) days prior to any other action.  If no record date is 
fixed by the Board of Directors, then the record date shall be as provided by 
applicable law.  A determination of stockholders of record entitled to notice 
of or to vote at a meeting of stockholders shall apply to any adjournment of 
the meeting; PROVIDED, HOWEVER, that the Board of Directors may fix a new 
record date for the adjourned meeting.

     SECTION 1.9:   LIST OF STOCKHOLDERS ENTITLED TO VOTE.  A complete list of
stockholders entitled to vote at any meeting of stockholders, arranged in
alphabetical order and showing the address of each stockholder and the number of
shares registered in the name of each stockholder, shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any stockholder who is present at the meeting.

     SECTION 1.10:  ACTION BY WRITTEN CONSENT OF STOCKHOLDERS. 

     (a)            PROCEDURE.  Unless otherwise provided by the Certificate of
Incorporation, any action required or permitted to be taken at any annual or
special meeting of the stockholders may be taken without a meeting, without
prior notice and without a vote, if a consent or consents in writing, setting
forth the action so taken, shall be signed by the holders of outstanding stock
having not less than the number of votes that would be necessary to authorize or
take such action at a meeting at which all shares entitled to vote thereon were
present and voted.  Written stockholder consents shall bear the date of
signature of each stockholder who signs the consent and shall be delivered to
the Corporation by delivery to its registered office in the State of Delaware,
to its principal place of business or to any officer or agent of the Corporation
having custody of the book in which proceedings of meetings of stockholders are
recorded.  Delivery made to the Corporation's registered office shall be by hand
or by certified or registered mail, return receipt requested.  No written
consent shall be effective to take the action set forth therein unless, within
sixty (60) days of the earliest dated consent delivered to the Corporation in
the manner provided above, written consents signed by a sufficient number of
stockholders to take the action set forth therein are delivered to the
Corporation in the manner provided above.

<PAGE>


     (b)            NOTICE OF CONSENT.  Prompt notice of the taking of corporate
action by stockholders without a meeting by less than unanimous written consent
of the stockholders shall be given to those stockholders who have not consented
thereto in writing and who, if the action had been taken at a meeting, would
have been entitled to notice of the meeting if the record date for such meeting
had been the date that written consents signed by a sufficient number of holders
to take the action were delivered to the Corporation.  In the case of a
Certificate Action (as defined below), if the Delaware General Corporation Law
so requires, such notice shall be given prior to filing of the certificate in
question.  If the action which is consented to requires the filing of a
certificate under the Delaware General Corporation Law (a "CERTIFICATE ACTION"),
then if the Delaware General Corporation Law so requires, the certificate so
filed shall state that written stockholder consent has been given in accordance
with Section 228 of the Delaware General Corporation Law and that written notice
of the taking of corporate action by stockholders without a meeting as described
herein has been given as provided in such section.

     SECTION 1.11:  INSPECTORS OF ELECTIONS.

     (a)            APPLICABILITY.  Unless otherwise provided in the
Corporation's Certificate of Incorporation or required by the Delaware General
Corporation Law, the following provisions of this Section 1.11 shall apply only
if and when the Corporation has a class of voting stock that is:  (i) listed on
a national securities exchange; (ii) authorized for quotation on an automated
interdealer quotation system of a registered national securities association; or
(iii) held of record by more than 2,000 stockholders; in all other cases,
observance of the provisions of this Section 1.11 shall be optional, and at the
discretion of the Corporation.  

     (b)            APPOINTMENT.  The Corporation shall, in advance of any
meeting of stockholders, appoint one or more inspectors of election to act at
the meeting and make a written report thereof.  The Corporation may designate
one or more persons as alternate inspectors to replace any inspector who fails
to act.  If no inspector or alternate is able to act at a meeting of
stockholders, the person presiding at the meeting shall appoint one or more
inspectors to act at the meeting.  

     (c)            INSPECTOR'S OATH.  Each inspector of election, before
entering upon the discharge of his duties, shall take and sign an oath
faithfully to execute the duties of inspector with strict impartiality and
according to the best of such inspector's ability.  

     (d)            DUTIES OF INSPECTORS.  At a meeting of stockholders, the
inspectors of election shall (i) ascertain the number of shares outstanding and
the voting power of each share, (ii) determine the shares represented at a
meeting and the validity of proxies and ballots, (iii) count all votes and
ballots, (iv) determine and retain for a reasonable period of time a record of
the disposition of any challenges made to any determination by the inspectors,
and (v) certify their determination of the number of shares represented at the
meeting, and their count of all votes and ballots.  The inspectors may appoint
or retain other persons or entities to assist the inspectors in the performance
of the duties of the inspectors.

<PAGE>


     (e)            OPENING AND CLOSING OF POLLS.  The date and time of the
opening and the closing of the polls for each matter upon which the stockholders
will vote at a meeting shall be announced by the chairperson of the meeting.  No
ballot, proxies or votes, nor any revocations thereof or changes thereto, shall
be accepted by the inspectors after the closing of the polls unless the Court of
Chancery upon application by a stockholder shall determine otherwise.

     (f)            DETERMINATIONS.  In determining the validity and counting of
proxies and ballots, the inspectors shall be limited to an examination of the
proxies, any envelopes submitted with those proxies, any information provided in
connection with proxies in accordance with Section 212(c)(2) of the Delaware
General Corporation Law, ballots and the regular books and records of the
Corporation, except that the inspectors may consider other reliable information
for the limited purpose of reconciling proxies and ballots submitted by or on
behalf of banks, brokers, their nominees or similar persons which represent more
votes than the holder of a proxy is authorized by the record owner to cast or
more votes than the stockholder holds of record.  If the inspectors consider
other reliable information for the limited purpose permitted herein, the
inspectors at the time they make their certification of their determinations
pursuant to this Section 1.11 shall specify the precise information considered
by them, including the person or persons from whom they obtained the
information, when the information was obtained, the means by which the
information was obtained and the basis for the inspectors' belief that such
information is accurate and reliable.

     SECTION 1.12:  NOTICE OF STOCKHOLDER BUSINESS; NOMINATIONS.

     (a)            ANNUAL MEETING OF STOCKHOLDERS.

          (i)       Nominations of persons for election to the Board of
Directors and the proposal of business to be considered by the stockholders
shall be made at an annual meeting of stockholders (A) pursuant to the
Corporation's notice of such meeting, (B) by or at the direction of the Board of

          (ii)      For nominations or other business to be properly brought
before an annual meeting by a stockholder pursuant to clause (C) of subparagraph
(a)(i) of this Section 1.12, the stockholder must have given timely notice
thereof in writing to the Secretary of the Corporation and such other business
must otherwise be a proper matter for stockholder action.  To be timely, a
stockholder's notice must be delivered to the Secretary at the principal
executive offices of the Corporation not later than the close of business on the
sixtieth (60th) day nor earlier than the close of business on the ninetieth
(90th) day prior to the first anniversary of the preceding year's annual meeting
(except in the case of the 1999 annual meeting, for which such notice shall be
timely if delivered in the same time period as if such meeting were a special
meeting governed by subparagraph (b) of this Section 1.12); PROVIDED, HOWEVER,
that in the event that the date of the annual meeting is more than thirty (30)
days before or more than sixty (60) days after such anniversary date, notice by
the stockholder to be timely must be so delivered not earlier than the close of
business on the ninetieth (90th) day prior to such annual meeting and not later
than the 


                                   -5-
<PAGE>

close of business on the later of the sixtieth (60th) day prior to such
annual meeting or the close of business on the tenth (10th) day following the
day on which public announcement of the date of such meeting is first made by
the Corporation.  Such stockholder's notice shall set forth: (a) as to each
person whom the stockholder proposes to nominate for election or reelection as a
director all information relating to such person that is required to be
disclosed in solicitations of proxies for election of directors, or is otherwise
required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "EXCHANGE ACT"), including such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected; (b) as to any other business that the stockholder proposes
to bring before the meeting, a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the
meeting and any material interest in such business of such stockholder and the
beneficial owner, if any, on whose behalf the proposal is made; and (c) as to
the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (1) the name and address of such
stockholder, as they appear on the Corporation's books, and of such beneficial
owner, and (2) the class and number of shares of the Corporation that are owned
beneficially and held of record by such stockholder and such beneficial owner.

          (iii)     Notwithstanding anything in the second sentence of
subparagraph (a)(ii) of this Section 1.12 to the contrary, in the event that the
number of directors to be elected to the Board of Directors of the Corporation
is increased and there is no public announcement by the Corporation naming all
of the nominees for director or specifying the size of the increased board of
directors at least seventy (70) days prior to the first anniversary of the
preceding year's annual meeting (or, if the annual meeting is held more than
thirty (30) days before or sixty (60) days after such anniversary date, at least
seventy (70) days prior to such annual meeting), a stockholder's notice required
by this Section 1.12 shall also be considered timely, but only with respect to
nominees for any new positions created by such increase, if it shall be
delivered to the Secretary of the Corporation at the principal executive office
of the Corporation not later than the close of business on the tenth (10th) day
following the day on which such public announcement is first made by the
Corporation.

     (b)            SPECIAL MEETINGS OF STOCKHOLDERS.  Only such business shall
be conducted at a special meeting of stockholders as shall have been brought
before the meeting pursuant to the Corporation's notice of such meeting. 
Nominations of persons for election to the Board of Directors may be made at a
special meeting of stockholders at which directors are to be elected pursuant to
the Corporation's notice of such meeting (i) by or at the direction of the Board
of Directors or (ii) provided that the Board of Directors has determined that
directors shall be elected at such meeting, by any stockholder of the
Corporation who is a stockholder of record at the time of giving of notice of
the special meeting, who shall be entitled to vote at the meeting and who
complies with the notice procedures set forth in this Section 1.12.  In the
event the Corporation calls a special meeting of stockholders for the purpose of
electing one or more directors to the Board of Directors, any such stockholder
may nominate a person or persons (as the case may be), for election to such
position(s) as specified in the Corporation's notice of meeting, if the
stockholder's notice required by subparagraph (a)(ii) of this Section 1.12 shall
be delivered to the Secretary of the Corporation at the principal executive
offices of the Corporation 

                                   -6-
<PAGE>

not earlier than the ninetieth (90th) day prior to such special meeting and 
not later than the close of business on the later of the sixtieth (60th) day 
prior to such special meeting or the tenth (10th) day following the day on 
which public announcement is first made of the date of the special meeting 
and of the nominees proposed by the Board of Directors to be elected at such 
meeting.

     (c)            GENERAL.

          (i)   Only such persons who are nominated in accordance with the
procedures set forth in this Section 1.12 shall be eligible to serve as
directors and only such business shall be conducted at a meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 1.12.  Except as otherwise provided by law or these
Bylaws, the chairperson of the meeting shall have the power and duty to
determine whether a nomination or any business proposed to be brought before the
meeting was made or proposed, as the case may be, in accordance with the
procedures set forth in this Section 1.12 and, if any proposed nomination or
business is not in compliance herewith, to declare that such defective proposal
or nomination shall be disregarded.

          (ii)  For purposes of this Section 1.12, the term
"PUBLIC ANNOUNCEMENT" shall mean disclosure in a press release reported by the
Dow Jones News Service, Associated Press or comparable national news service or
in a document publicly filed by the Corporation with the Securities and Exchange
Commission pursuant to section 13, 14 or 15(d) of the Exchange Act.

          (iii) Notwithstanding the foregoing provisions of this Section 1.12,
a stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to the matters set
forth herein.  Nothing in this Section 1.12 shall be deemed to affect any rights
of stockholders to request inclusion of proposals in the Corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

                                     ARTICLE II
                                          
                                 BOARD OF DIRECTORS

     SECTION 2.1:   NUMBER; QUALIFICATIONS.  The Board of Directors shall
consist of one or more members.  The initial number of directors shall be seven
(7), and thereafter shall be fixed from time to time by resolution of the Board
of Directors.  No decrease in the authorized number of directors constituting
the Board of Directors shall shorten the term of any incumbent director. 
Directors need not be stockholders of the Corporation.

     SECTION 2.2:   ELECTION; RESIGNATION; REMOVAL; VACANCIES.  Subject to the
rights of the holders of any series of Preferred Stock to elect additional
directors under specified circumstances, following the closing of the
corporation's initial public offering pursuant to an effective registration
statement under the Securities Act of 1933, as amended, covering the offer and
sale of Common Stock to the public (the "INITIAL PUBLIC OFFERING"), the
directors shall be divided, with respect to the time for which they severally
hold office, into three classes designated as Class I, Class II and Class III,
respectively.  Directors shall be assigned to each 


                                   -7-
<PAGE>


class in accordance with a resolution or resolutions adopted by the Board of 
Directors, with the number of directors in each class to be divided as 
equally as reasonably possible.  The term of office of the Class I directors 
shall expire at the corporation's first annual meeting of stockholders 
following the closing of the Initial Public Offering, the term of office of 
the Class II directors shall expire at the corporation's second annual 
meeting of stockholders following the closing of the Initial Public Offering, 
and the term of office of the Class III directors shall expire at the 
corporation's third annual meeting of stockholders following the closing of 
the Initial Public Offering.  At each annual meeting of stockholders 
commencing with the first annual meeting of stockholders following the 
closing of the Initial Public Offering, directors elected to succeed those 
directors of the class whose terms then expire shall be elected for a term of 
office to expire at the third succeeding annual meeting of stockholders after 
their election.  Prior to the closing of the Initial Public Offering, each 
director shall hold office until the next annual meeting of stockholders and 
until such director's successor is elected and qualified, or until such 
director's earlier death, resignation or removal.  Any director may resign at 
any time upon written notice to the Corporation.  Subject to the rights of 
the holders of any series of Preferred Stock, any vacancy occurring in the 
Board of Directors for any cause, and any newly created directorship 
resulting from any increase in the authorized number of directors, shall, 
unless (i) the Board of Directors determines by resolution that any such 
vacancies or newly created directorships shall be filled by the stockholders, 
or (ii) as otherwise provided by law, be filled only by the affirmative vote 
of a majority of the directors then in office, although less than a quorum, 
or by a sole remaining director, and not by the stockholders.  Any director 
elected in accordance with the preceding sentence shall hold office for the 
remainder of the full term of the director for which the vacancy was created 
or occurred.  Subject to the rights of any holders of Preferred Stock, any 
director or the entire Board of Directors may be removed, with or without 
cause, by the holders of a majority of the shares then entitled to vote at an 
election of directors; PROVIDED, HOWEVER, that a director may not be removed 
without cause if the votes cast against removal of the director, or not 
consenting in writing to the removal, would be sufficient to elect the 
director if voted cumulatively (without regard to whether shares may 
otherwise be voted cumulatively) at an election at which the same total 
number of votes were cast (or, if the action is taken by written consent, all 
shares entitled to vote were voted) and either the number of directors 
elected at the most recent annual meeting of stockholders, or if greater, the 
number of directors for whom removal is being sought, were then being elected.

     SECTION 2.3:   REGULAR MEETINGS.  Regular meetings of the Board of
Directors may be held at such places, within or without the State of Delaware,
and at such times as the Board of Directors may from time to time determine. 
Notice of regular meetings need not be given if the date, times and places
thereof are fixed by resolution of the Board of Directors.

     SECTION 2.4:   SPECIAL MEETINGS.  Special meetings of the Board of
Directors may be called by the Chairperson of the Board of Directors, the
President or a majority of the members of the Board of Directors then in office
and may be held at any time, date or place, within or without the State of
Delaware, as the person or persons calling the meeting shall fix.  Notice of the
time, date and place of such meeting shall be given, orally or in writing, by
the person or persons calling the meeting to all directors at least four (4)
days before the meeting if the notice is mailed, or at least twenty-four (24)
hours before the meeting if such notice is given by 


                                   -8-
<PAGE>


telephone, hand delivery, telegram, telex, mailgram, facsimile or similar 
communication method.  Unless otherwise indicated in the notice, any and all 
business may be transacted at a special meeting.

     SECTION 2.5:   TELEPHONIC MEETINGS PERMITTED.  Members of the Board of
Directors, or any committee of the Board, may participate in a meeting of the
Board or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to
conference telephone or similar communications equipment shall constitute
presence in person at such meeting.

     SECTION 2.6:   QUORUM; VOTE REQUIRED FOR ACTION.  At all meetings of the
Board of Directors a majority of the total number of authorized directors shall
constitute a quorum for the transaction of business.  Except as otherwise
provided herein or in the Certificate of Incorporation, or required by law, the
vote of a majority of the directors present at a meeting at which a quorum is
present shall be the act of the Board of Directors.

     SECTION 2.7:   ORGANIZATION.  Meetings of the Board of Directors shall be
presided over by the Chairperson of the Board of Directors, or in such person's
absence by the President, or in such person's absence by a chairperson chosen at
the meeting.  The Secretary shall act as secretary of the meeting, but in such
person's absence the chairperson of the meeting may appoint any person to act as
secretary of the meeting.

     SECTION 2.8:   WRITTEN ACTION BY DIRECTORS.  Any action required or
permitted to be taken at any meeting of the Board of Directors, or of any
committee thereof, may be taken without a meeting if all members of the Board or
such committee, as the case may be, consent thereto in writing, and the writing
or writings are filed with the minutes of proceedings of the Board or committee,
respectively.

     SECTION 2.9:   POWERS.  The Board of Directors may, except as otherwise
required by law or the Certificate of Incorporation, exercise all such powers
and do all such acts and things as may be exercised or done by the Corporation.

     SECTION 2.10:  COMPENSATION OF DIRECTORS.  Directors, as such, may receive,
pursuant to a resolution of the Board of Directors, fees and other compensation
for their services as directors, including without limitation their services as
members of committees of the Board of Directors.

                                     ARTICLE III

                                      COMMITTEES

     SECTION 3.1:   COMMITTEES.  The Board of Directors may designate one or
more committees, each committee to consist of one or more of the directors of
the Corporation.  The Board of Directors may designate one or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee.  In the absence or disqualification of a
member of the committee, the member or members thereof 


                                   -9-
<PAGE>

present at any meeting of such committee who are not disqualified from 
voting, whether or not such member or members constitute a quorum, may 
unanimously appoint another member of the Board of Directors to act at the 
meeting in place of any such absent or disqualified member.  Any such 
committee, to the extent provided in a resolution of the Board of Directors, 
shall have and may exercise all the powers and authority of the Board of 
Directors in the management of the business and affairs of the Corporation 
and may authorize the seal of the Corporation to be affixed to all papers 
that may require it; but no such committee shall have the power or authority 
in reference to the following matters:  (i) approving or adopting, or

                                   INDEMNIFICATION

     SECTION 6.1    INDEMNIFICATION OF OFFICERS AND DIRECTORS.  Each person who
was or is made a party to, or is threatened to be made a party to, or is
involved in any action, suit or proceeding, whether civil, criminal,
administrative or investigative (a "PROCEEDING"), by reason of the fact that
such person (or a person of whom such person is the legal representative), is or
was a director or officer of the Corporation or a Reincorporated Predecessor (as
defined below) or is or was serving at the request of the Corporation or a
Reincorporated Predecessor (as defined below) as a director or officer of
another corporation, or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, shall be
indemnified and held harmless by the Corporation to the fullest extent permitted
by the Delaware General Corporation Law, against all expenses, liability and
loss (including attorneys' fees, judgments, fines, ERISA excise taxes and
penalties and amounts paid or to be paid in settlement) reasonably incurred or
suffered by such person in connection therewith, provided such person acted in
good faith and in a manner which the person reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe the person's
conduct was unlawful.  Such indemnification shall continue as to a person who
has ceased to be a director or officer and shall inure to the benefit of such
person's heirs, executors and administrators.  Notwithstanding the foregoing,
the Corporation shall indemnify any such person seeking indemnity in connection
with a Proceeding (or part thereof) initiated by such person only if such
Proceeding (or part thereof) was authorized by the Board of Directors of the
Corporation.  As used herein, the term "REINCORPORATED PREDECESSOR" means a
corporation that is merged with and into the Corporation in a statutory merger
where (a) the Corporation is the surviving corporation of such merger; (b) the
primary purpose of such merger is to change the corporate domicile of the
Reincorporated Predecessor to Delaware.

     SECTION 6.2:   ADVANCE OF EXPENSES.  The Corporation shall pay all expenses
(including attorneys' fees) incurred by such a director or officer in defending
any such Proceeding as they are incurred in advance of its final disposition;
PROVIDED, HOWEVER, that if the Delaware General Corporation Law then so
requires, the payment of such expenses incurred by such a director or officer in
advance of the final disposition of such Proceeding shall be made only upon
delivery to the Corporation of an undertaking, by or on behalf of such director
or officer, to repay all amounts so advanced if it should be determined
ultimately that such director or officer is not entitled to be indemnified under
this Article VI or otherwise; and PROVIDED, FURTHER, that the Corporation shall
not be required to advance any expenses to a person against whom the Corporation
directly brings a claim, in a Proceeding, alleging that such person has breached
such person's duty of loyalty to the Corporation, committed an act or omission
not in good faith or that 


                                   -13-
<PAGE>


involves intentional misconduct or a knowing violation of law, or derived an 
improper personal benefit from a transaction.

     SECTION 6.3:   NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on any
person in this Article VI shall not be exclusive of any other right that such
person may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, Bylaw, agreement, vote or consent of stockholders
or disinterested directors, or otherwise.  Additionally, nothing in this Article
VI shall limit the ability of the Corporation, in its discretion, to indemnify
or advance expenses to persons whom the Corporation is not obligated to
indemnify or advance expenses pursuant to this Article VI.

     SECTION 6.4:   INDEMNIFICATION CONTRACTS.  The Board of Directors is
authorized to cause the Corporation to enter into indemnification contracts with
any director, officer, employee or agent of the Corporation, or any person
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, including employee benefit plans, providing indemnification rights
to such person.  Such rights may be greater than those provided in this Article
VI.

     SECTION 6.5:   EFFECT OF AMENDMENT.  Any amendment, repeal or modification
of any provision of this Article VI shall be prospective only, and shall not
adversely affect any right or protection conferred on a person pursuant to this
Article VI and existing at the time of such amendment, repeal or modification.

                                     ARTICLE VII

                                       NOTICES

     SECTION 7.1:   NOTICE.  Except as otherwise specifically provided herein or
required by law, all notices required to be given pursuant to these Bylaws shall
be in writing and may in every instance be effectively given by hand delivery
(including use of a delivery service), by depositing such notice in the mail,
postage prepaid, or by sending such notice by prepaid telegram, telex, overnight
express courier, mailgram or facsimile.  Any such notice shall be addressed to
the person to whom notice is to be given at such person's address as it appears
on the records of the Corporation.  The notice shall be deemed given (i) in the
case of hand delivery, when received by the person to whom notice is to be given
or by any person accepting such notice on behalf of such person, (ii) in the
case of delivery by mail, upon deposit in the mail, (iii) in the case of
delivery by overnight express courier, when dispatched, and (iv) in the case of
delivery via telegram, telex, mailgram or facsimile, when dispatched.

     SECTION 7.2:   WAIVER OF NOTICE.  Whenever notice is required to be given
under any provision of these Bylaws, a written waiver of notice, signed by the
person entitled to notice, whether before or after the time stated therein,
shall be deemed equivalent to notice.  Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when the person attends a
meeting for the express purpose of objecting at the beginning of the meeting to
the transaction of any business because the meeting is not lawfully called or
convened.  Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the 

                                   -14-
<PAGE>

stockholders, directors or members of a committee of directors need be 
specified in any written waiver of notice.

                                     ARTICLE VIII

                                 INTERESTED DIRECTORS

     SECTION 8.1:   INTERESTED DIRECTORS; QUORUM.  No contract or transaction
between the Corporation and one or more of its directors or officers, or between
the Corporation and any other corporation, partnership, association or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or committee thereof that
authorizes the contract or transaction, or solely because his, her or their
votes are counted for such purpose, if: (i) the material facts as to his, her or
their relationship or interest and as to the contract or transaction are
disclosed or are known to the Board of Directors or the committee, and the Board
of Directors or committee in good faith authorizes the contract or transaction
by the affirmative votes of a majority of the disinterested directors, even
though the disinterested directors be less than a quorum; (ii) the material
facts as to his, her or their relationship or interest and as to the contract or
transaction are disclosed or are known to the stockholders entitled to vote
thereon, and the contract or transaction is specifically approved in good faith
by vote of the stockholders; or (iii) the contract or transaction is fair as to
the Corporation as of the time it is authorized, approved or ratified by the
Board of Directors, a committee thereof, or the stockholders.  Interested
directors may be counted in determining the presence of a quorum at a meeting of
the Board of Directors or of a committee which authorizes the contract or
transaction.

                                      ARTICLE IX

Directors.

     SECTION 9.3:   FORM OF RECORDS.  Any records maintained by the Corporation
in the regular course of its business, including its stock ledger, books of
account and minute books, may be kept on, or be in the form of, magnetic tape,
diskettes, photographs, microphotographs or any other information storage
device, provided that the records so kept can be converted into clearly legible
form within a reasonable time.  The Corporation shall so convert any records so
kept upon the request of any person entitled to inspect the same.

                                   -15-

     SECTION 9.4:   RELIANCE UPON BOOKS AND RECORDS.  A member of the Board of
Directors, or a member of any committee designated by the Board of Directors
shall, in the performance of such person's duties, be fully protected in relying
in good faith upon records of the Corporation and upon such information,
opinions, reports or statements presented to the Corporation by any of
the Corporation's officers or employees, or committees of the Board of
Directors, or by any other person as to matters the member reasonably believes
are within such other person's professional or expert competence and who has
been selected with reasonable care by or on behalf of the Corporation.

     SECTION 9.5:   CERTIFICATE OF INCORPORATION GOVERNS.  In the event of any
conflict between the provisions of the Corporation's Certificate of
Incorporation and Bylaws, the provisions of the Certificate of Incorporation
shall govern.

     SECTION 9.6:   SEVERABILITY.  If any provision of these Bylaws shall be

the Corporation's Certificate of Incorporation, then such provision shall
nonetheless be enforced to the maximum extent possible consistent with such
holding and the remaining provisions of these Bylaws (including without
limitation, all portions of any section of these Bylaws containing any such
provision held to be invalid, illegal, unenforceable or in conflict with the
Certificate of Incorporation, that are not themselves invalid, illegal,
unenforceable or in conflict with the Certificate of Incorporation) shall remain
in full force and effect.

                                INDEMNITY AGREEMENT

     This Indemnity Agreement (this "AGREEMENT"), dated as of _____________,
____, is made by and between AdForce, Inc., a Delaware corporation (the
"COMPANY"), and _________________, a director and/or officer of the Company (the
"INDEMNITEE").

                                      RECITALS

     A.   The Company is aware that competent and experienced persons are
increasingly reluctant to serve as directors or officers of corporations unless
they are protected by comprehensive liability insurance and/or indemnification,
due to increased exposure to litigation costs and risks resulting from their
service to such corporations, and due to the fact that the exposure frequently
bears no reasonable relationship to the compensation of such directors and
officers;

     B.   Based upon their experience as business managers, the Board of
Directors of the Company (the "BOARD") has concluded that, to retain and attract
talented and experienced individuals to serve as officers and directors of the
Company, and to encourage such individuals to take the business risks necessary
for the success of the Company, it is necessary for the Company contractually to
indemnify officers and directors and to assume for itself maximum liability for
expenses and damages in connection with claims against such officers and
directors in connection with their service to the Company;

     C.   Section 145 of the General Corporation Law of Delaware, under which
the Company is organized (the "LAW"), empowers the Company to indemnify by
agreement its officers, directors, employees and agents, and persons who serve,
at the request of the Company, as directors, officers, employees or agents of
other corporations or enterprises, and expressly provides that the
indemnification provided by the Law is not exclusive; and

     D.   The Company desires and has requested the Indemnitee to serve or
continue to serve as a director or officer of the Company free from undue
concern for claims for damages arising out of or related to such services to the
Company.

     NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby
agree as follows:

     1.   DEFINITIONS.

          1.1    AGENT.  For the purposes of this Agreement, "AGENT" of the
Company means any person who is or was a director or officer of the Company or a
subsidiary of the Company; or is or was serving at the request of, for the
convenience of, or to represent the interest of the Company or a subsidiary of
the Company as a director or officer of another foreign or domestic corporation,
partnership, joint venture, trust or other enterprise or an affiliate of the


<PAGE>

Company; or was a director or officer of a foreign or domestic corporation which
was a predecessor corporation of the Company, including, without limitation,
Imgis, Inc., a California corporation, or was a director or officer of another
enterprise or affiliate of the Company at the request of, for the convenience
of, or to represent the interests of such predecessor corporation.  The term
"ENTERPRISE" includes any employee benefit plan of the Company, its
subsidiaries, affiliates and predecessor corporations.

          1.2    EXPENSES.  For purposes of this Agreement, "EXPENSES" includes
all direct and indirect costs of any type or nature whatsoever (including,
without limitation, all attorneys' fees and related disbursements and other
out-of-pocket costs) actually and reasonably incurred by the Indemnitee in
connection with the investigation, defense or appeal of a proceeding or
establishing or enforcing a right to indemnification or advancement of expenses
under this Agreement, Section 145 or otherwise; PROVIDED, HOWEVER, that expenses
shall not include any judgments, fines, ERISA excise taxes or penalties or
amounts paid in settlement of a proceeding.

          1.3    PROCEEDING.  For the purposes of this Agreement, "PROCEEDING"
means any threatened, pending or completed action, suit or other proceeding,
whether civil, criminal, administrative, investigative or any other type
whatsoever.

          1.4    SUBSIDIARY.  For purposes of this Agreement, "SUBSIDIARY"
means any corporation of which more than fifty percent (50%) of the outstanding
voting securities is owned directly or indirectly by the Company, by the Company
and one or more of its subsidiaries or by one or more of the Company's
subsidiaries.

     2.   AGREEMENT TO SERVE.  The Indemnitee agrees to serve and/or continue to
serve as an agent of the Company, at the will of the Company (or under separate
agreement, if such agreement exists), in the capacity the Indemnitee currently
serves as an agent of the Company, faithfully and to the best of his ability, so
long as he is duly appointed or elected and qualified in accordance with the
applicable provisions of the charter documents of the Company or any subsidiary
of the Company; PROVIDED, HOWEVER, that the Indemnitee may at any time and for
any reason resign from such position (subject to any contractual obligation that
the Indemnitee may have assumed apart from this Agreement), and the Company or
any subsidiary shall have no obligation under this Agreement to continue the
Indemnitee in any such position.

     3.   DIRECTORS' AND OFFICERS' INSURANCE.  The Company shall, to the extent
that the Board determines it to be economically reasonable, maintain a policy of
directors' and officers' liability insurance ("D&O INSURANCE"), on such terms
and conditions as may be approved by the Board.

     4.   MANDATORY INDEMNIFICATION.  Subject to Section 9 below, the Company
shall indemnify the Indemnitee:

          4.1    THIRD PARTY ACTIONS.  If the Indemnitee is a person who was or
is a party or is threatened to be made a party to any proceeding (other than an
action by or in the right of the Company) by reason of the fact that he is or
was an agent of the Company, or by reason of


                                         -2-
<PAGE>

anything done or not done by him in any such capacity, against any and all
expenses and liabilities of any type whatsoever (including, but not limited to,
judgments, fines, ERISA excise taxes or penalties and amounts paid in
settlement) actually and reasonably incurred by him in connection with the
investigation, defense, settlement or appeal of such proceeding if he acted in
good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the Company and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful; and

          4.2    DERIVATIVE ACTIONS.  If the Indemnitee is a person who was or
is a party or is threatened to be made a party to any proceeding by or in the
right of the Company to procure a judgment in its favor by reason of the fact
that he is or was an agent of the Company, or by reason of anything done or not
done by him in any such capacity, against any amounts paid in settlement of any
such proceeding and all expenses actually and reasonably incurred by him in
connection with the investigation, defense, settlement or appeal of such
proceeding if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Company; EXCEPT that no
indemnification under this subsection shall be made in respect of any claim,
issue or matter as to which such person shall have been finally adjudged to be
liable to the Company by a court of competent jurisdiction due to willful
misconduct of a culpable nature in the performance of his duty to the Company,
unless and only to the extent that the Court of Chancery or the court in which
such proceeding was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such amounts which the
Court of Chancery or such other court shall deem proper; and

          4.3    EXCEPTION FOR AMOUNTS COVERED BY INSURANCE.  Notwithstanding
the foregoing, the Company shall not be obligated to indemnify the Indemnitee
for expenses or liabilities of any type whatsoever (including, but not limited
to, judgments, fines, ERISA excise taxes or penalties and amounts paid in
settlement) to the extent such have been paid directly to the Indemnitee by D&O
Insurance.

     5.   PARTIAL INDEMNIFICATION AND CONTRIBUTION.

          5.1    PARTIAL INDEMNIFICATION.  If the Indemnitee is entitled under
any provision of this Agreement to indemnification by the Company for some or a
portion of any expenses or liabilities of any type whatsoever (including, but
not limited to, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) incurred by him in the investigation, defense, settlement or
appeal of a proceeding but is not entitled, however, to indemnification for all
of the total amount thereof, then the Company shall nevertheless indemnify the
Indemnitee for such total amount except as to the portion thereof to which the
Indemnitee is not entitled to indemnification.

          5.2    CONTRIBUTION.  If the Indemnitee is not entitled to the
indemnification provided in Section 4 for any reason other than the statutory
limitations set forth in the Law, then in respect of any threatened, pending or
completed proceeding in which the Company is jointly


                                         -3-
<PAGE>

liable with the Indemnitee (or would be if joined in such proceeding), the
Company shall contribute to the amount of expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
and paid or payable by the Indemnitee in such proportion as is appropriate to
reflect (i) the relative benefits received by the Company on the one hand and
the Indemnitee on the other hand from the transaction from which such proceeding
arose and (ii) the relative fault of the Company on the one hand and of the
Indemnitee on the other hand in connection with the events which resulted in
such expenses, judgments, fines or settlement amounts, as well as any other
relevant equitable considerations.  The relative fault of the Company on the one
hand and of the Indemnitee on the other hand shall be determined by reference
to, among other things, the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent the circumstances resulting in
such expenses, judgments, fines or settlement amounts.  The Company agrees that
it would not be just and equitable if contribution pursuant to this Section 5
were determined by pro rata allocation or any other method of allocation which
does not take account of the foregoing equitable considerations.

     6.   MANDATORY ADVANCEMENT OF EXPENSES.

          6.1    ADVANCEMENT.  Subject to Section 9 below, the Company shall
advance all expenses incurred by the Indemnitee in connection with the
investigation, defense, settlement or appeal of any proceeding to which the
Indemnitee is a party or is threatened to be made a party by reason of the fact
that the Indemnitee is or was an agent of the Company or by reason of anything
done or not done by him in any such capacity.  The Indemnitee hereby undertakes
to promptly repay such amounts advanced only if, and to the extent that, it
shall ultimately be determined that the Indemnitee is not entitled to be
indemnified by the Company under the provisions of this Agreement, the
Certificate of Incorporation or Bylaws of the Company, the Law or otherwise.
The advances to be made hereunder shall be paid by the Company to the Indemnitee
within thirty (30) days following delivery of a written request therefor by the
Indemnitee to the Company.

          6.2    EXCEPTION.  Notwithstanding the foregoing provisions of this
Section 6, the Company shall not be obligated to advance any expenses to the
Indemnitee arising from a lawsuit filed directly by the Company against the
Indemnitee if an absolute majority of the members of the Board reasonably
determines in good faith, within thirty (30) days of the Indemnitee's request to
be advanced expenses, that the facts known to them at the time such
determination is made demonstrate clearly and convincingly that the Indemnitee
acted in bad faith.  If such a determination is made, the Indemnitee may have
such decision reviewed by another forum, in the manner set forth in Sections
8.3, 8.4 and 8.5 hereof, with all references therein to "indemnification" being
deemed to refer to "advancement of expenses," and the burden of proof shall be
on the Company to demonstrate clearly and convincingly that, based on the facts
known at the time, the Indemnitee acted in bad faith.  The Company may not avail
itself of this Section 6.2 as to a given lawsuit if, at any time after the
occurrence of the activities or omissions that are the primary focus of the
lawsuit, the Company has undergone a change in control.  For this purpose, a
change in control shall mean a given person or group of affiliated


                                         -4-
<PAGE>

persons or groups increasing their beneficial ownership interest in the Company
by at least twenty (20) percentage points without advance Board approval.

     7.   NOTICE AND OTHER INDEMNIFICATION PROCEDURES.

          7.1    Promptly after receipt by the Indemnitee of notice of the
commencement of or the threat of commencement of any proceeding, the Indemnitee
shall, if the Indemnitee believes that indemnification with respect thereto may
be sought from the Company under this Agreement, notify the Company of the
commencement or threat of commencement thereof.

          7.2    If, at the time of the receipt of a notice of the commencement
of a proceeding pursuant to Section 7.1 hereof, the Company has D&O Insurance in
effect, the Company shall give prompt notice of the commencement of such
proceeding to the insurers in accordance with the procedures set forth in the
respective policies.  The Company shall thereafter take all necessary or
desirable action to cause such insurers to pay, on behalf of the Indemnitee, all
amounts payable as a result of such proceeding in accordance with the terms of
such D&O Insurance policies.

          7.3    In the event the Company shall be obligated to advance the
expenses for any proceeding against the Indemnitee, the Company, if appropriate,
shall be entitled to assume the defense of such proceeding, with counsel
approved by the Indemnitee (which approval shall not be unreasonably withheld),
upon the delivery to the Indemnitee of written notice of its election to do so.
After delivery of such notice, approval of such counsel by the Indemnitee and
the retention of such counsel by the Company, the Company will not be liable to
the Indemnitee under this Agreement for any fees of counsel subsequently
incurred by the Indemnitee with respect to the same proceeding, PROVIDED that:
(a) the Indemnitee shall have the right to employ his own counsel in any such
proceeding at the Indemnitee's expense; (b) the Indemnitee shall have the right
to employ his own counsel in connection with any such proceeding, at the expense
of the Company, if such counsel serves in a review, observer, advice and
counseling capacity and does not otherwise materially control or participate in
the defense of such proceeding; and (c) if (i) the employment of counsel by the
Indemnitee has been previously authorized by the Company, (ii) the Indemnitee
shall have reasonably concluded that there may be a conflict of interest between
the Company and the Indemnitee in the conduct of any such defense or (iii) the
Company shall not, in fact, have employed counsel to assume the defense of such
proceeding, then the fees and expenses of the Indemnitee's counsel shall be at
the expense of the Company.

     8.   DETERMINATION OF RIGHT TO INDEMNIFICATION.

          8.1    To the extent the Indemnitee has been successful on the merits
or otherwise in defense of any proceeding referred to in Section 4.1 or 4.2 of
this Agreement or in the defense of any claim, issue or matter described
therein, the Company shall indemnify the Indemnitee against expenses actually
and reasonably incurred by him in connection with the investigation, defense or
appeal of such proceeding, or such claim, issue or matter, as the case may be.


                                         -5-
<PAGE>

          8.2    In the event that Section 8.1 is inapplicable, or does not
apply to the entire proceeding, the Company shall nonetheless indemnify the
Indemnitee unless the Company shall prove by clear and convincing evidence to a
forum listed in Section 8.3 below that the Indemnitee has not met the applicable
standard of conduct required to entitle the Indemnitee to such indemnification.

          8.3    The Indemnitee shall be entitled to select the forum in which
the validity of the Company's claim under Section 8.2 hereof that the Indemnitee
is not entitled to indemnification will be heard from among the following,
EXCEPT that the Indemnitee can select a forum consisting of the stockholders of
the Company only with the approval of the Company:

                 (a)     A quorum of the Board consisting of directors who are
not parties to the proceeding for which indemnification is being sought;

                 (b)     The stockholders of the Company;

                 (c)     Legal counsel mutually agreed upon by the Indemnitee
and the Board, which counsel shall make such determination in a written opinion;

                 (d)     A panel of three arbitrators, one of whom is selected
by the Company, another of whom is selected by the Indemnitee and the last of
whom is selected by the first two arbitrators so selected; or

                 (e)     The Court of Chancery of Delaware or other court having
jurisdiction of subject matter and the parties.

          8.4    As soon as practicable, and in no event later than thirty (30)
days after the forum has been selected pursuant to Section 8.3 above, the
Company shall, at its own expense, submit to the selected forum its claim that
the Indemnitee is not entitled to indemnification, and the Company shall act in
the utmost good faith to assure the Indemnitee a complete opportunity to defend
against such claim.

          8.5    If the forum selected in accordance with Section 8.3 hereof is
not a court, then after the final decision of such forum is rendered, the
Company or the Indemnitee shall have the right to apply to the Court of Chancery
of Delaware, the court in which the proceeding giving rise to the Indemnitee's
claim for indemnification is or was pending or any other court of competent
jurisdiction, for the purpose of appealing the decision of such forum, PROVIDED
that such right is executed within sixty (60) days after the final decision of
such forum is rendered.  If the forum selected in accordance with Section 8.3
hereof is a court, then the rights of the Company or the Indemnitee to appeal
any decision of such court shall be governed by the applicable laws and rules
governing appeals of the decision of such court.

          8.6    Notwithstanding any other provision in this Agreement to the
contrary, the Company shall indemnify the Indemnitee against all expenses
incurred by the Indemnitee in connection with any hearing or proceeding under
this Section 8 involving the Indemnitee and


                                         -6-
<PAGE>

against all expenses incurred by the Indemnitee in connection with any other
proceeding between the Company and the Indemnitee involving the interpretation
or enforcement of the rights of the Indemnitee under this Agreement unless a
court of competent jurisdiction finds that each of the material claims and/or
defenses of the Indemnitee in any such proceeding was frivolous or not made in
good faith.

     9.   EXCEPTIONS.  Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          9.1    CLAIMS INITIATED BY INDEMNITEE.  To indemnify or advance
expenses to the Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by the Indemnitee and not by way of defense, EXCEPT with
respect to proceedings specifically authorized by the Board or brought to
establish or enforce a right to indemnification and/or advancement of expenses
arising under this Agreement, the charter documents of the Company or any
subsidiary or any statute or law or otherwise, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board finds it to be appropriate; or

          9.2    UNAUTHORIZED SETTLEMENTS.  To indemnify the Indemnitee
hereunder for any amounts paid in settlement of a proceeding unless the Company
consents in advance in writing to such settlement, which consent shall not be
unreasonably withheld; or

          9.3    SECURITIES LAW ACTIONS.  To indemnify the Indemnitee on
account of any suit in which judgment is rendered against the Indemnitee for an
accounting of profits made from the purchase or sale by the Indemnitee of
securities of the Company pursuant to the provisions of Section l6(b) of the
Securities Exchange Act of 1934 and amendments thereto or similar provisions of
any federal, state or local statutory law; or

          9.4    UNLAWFUL INDEMNIFICATION.  To indemnify the Indemnitee if a
final decision by a court having jurisdiction in the matter shall determine that
such indemnification is not lawful.  In this respect, the Company and the
Indemnitee have been advised that the Securities and Exchange Commission takes
the position that indemnification for liabilities arising under the federal
securities laws is against public policy and is, therefore, unenforceable and
that claims for indemnification should be submitted to appropriate courts for
adjudication.

     10.  NON-EXCLUSIVITY.  The provisions for indemnification and advancement
of expenses set forth in this Agreement shall not be deemed exclusive of any
other rights which the Indemnitee may have under any provision of law, the
Company's Certificate of Incorporation or Bylaws, the vote of the Company's
stockholders or disinterested directors, other agreements or otherwise, both as
to action in the Indemnitee's official capacity and to action in another
capacity while occupying his position as an agent of the Company, and the
Indemnitee's rights hereunder shall continue after the Indemnitee has ceased
acting as an agent of the Company and shall inure to the benefit of the heirs,
executors and administrators of the Indemnitee.

                             1999 EQUITY INCENTIVE PLAN

                            As Adopted February 18, 1999


     1.    PURPOSE.  The purpose of this Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses.  Capitalized terms not defined in the text are defined in Section 23.

     2.    SHARES SUBJECT TO THE PLAN.

           2.1   NUMBER OF SHARES AVAILABLE.  Subject to Sections 2.2 and 18,
the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 2,000,000 Shares plus Shares that are subject to:
(a) issuance upon exercise of an Option but cease to be subject to such Option
for any reason other than exercise of such Option; (b) an Award granted
hereunder but are forfeited or are repurchased by the Company at the original
issue price; and (c) an Award that otherwise terminates without Shares being
issued.  In addition, any authorized shares not issued or subject to outstanding
grants under the Imgis 1997 Stock Option Plan (the "PRIOR PLAN") on the
Effective Date (as defined below) and any shares issued under the Prior Plan
that are forfeited or repurchased by the Company or that are issuable upon
exercise of options granted pursuant to the Prior Plan that expire or become
unexercisable for any reason without having been exercised in full, will no
longer be available for grant and issuance under the Prior Plan, but will be
available for grant and issuance under this Plan.  At all times the Company
shall reserve and keep available a sufficient number of Shares as shall be
required to satisfy the requirements of all outstanding Options granted under
this Plan and all other outstanding but unvested Awards granted under this Plan.

           2.2   ADJUSTMENT OF SHARES.  In the event that the number of
outstanding shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the stockholders of the
Company and compliance with applicable securities laws; PROVIDED, HOWEVER, that
fractions of a Share will not be issued but will either be replaced by a cash
payment equal to the Fair Market Value of such fraction of a Share or will be
rounded up to the nearest whole Share, as determined by the Committee.

     3.    ELIGIBILITY.  ISOs (as defined in Section 5 below) may be granted
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company.  All other Awards may
be granted to employees, officers, directors, consultants, independent
contractors and advisors of the Company or any Parent or Subsidiary of the
Company; PROVIDED such consultants, contractors and advisors render bona fide
services not in connection with the offer and sale of securities in a
capital-raising transaction.  No person will be eligible to receive more than
1,500,000 Shares in any calendar year under this Plan pursuant to the grant of
Awards hereunder, other than new employees of the Company or of a Parent or
Subsidiary of the Company (including new employees who are also officers and
directors of the Company or any Parent or Subsidiary of the Company), who are
eligible to receive up to a maximum of 1,800,000 Shares in the calendar year in
which they commence their employment.  A person may be granted more than one
Award under this Plan.

     4.    ADMINISTRATION.

           4.1   COMMITTEE AUTHORITY.  This Plan will be administered by the
Committee or by the Board acting as the Committee.  Subject to the general
purposes, terms and conditions of this Plan, and to the direction of the Board,
the Committee will have full power to implement and carry out this Plan.
Without limitation, the Committee will have the authority to:

     (a)   construe and interpret this Plan, any Award Agreement and any other
           agreement or document executed pursuant to this Plan;

           Plan or any Award;

     (c)   select persons to receive Awards;

     (d)   determine the form and terms of Awards;

     (e)   determine the number of Shares or other consideration subject to
           Awards;

     (f)   determine whether Awards will be granted singly, in combination with,
           in tandem with, in replacement of, or as alternatives to, other
           Awards under this Plan or any other incentive or compensation plan of
           the Company or any Parent or Subsidiary of the Company;

     (g)   grant waivers of Plan or Award conditions;

     (h)   determine the vesting, exercisability and payment of Awards;

     (i)   correct any defect, supply any omission or reconcile any
           inconsistency in this Plan, any Award or any Award Agreement;

     (j)   determine whether an Award has been earned; and

     (k)   make all other determinations necessary or advisable for the
           administration of this Plan.

           4.2   COMMITTEE DISCRETION.  Any determination made by the Committee
with respect to any Award will be made in its sole discretion at the time of
grant of the Award or, unless in contravention of any express term of this Plan
or Award, at any later time, and such determination will be final and binding on
the Company and on all persons having an interest in any Award under this Plan.
The Committee may delegate to one or more officers of the Company the authority
to grant an Award under this Plan to Participants who are not Insiders of the
Company.

     5.    OPTIONS.  The Committee may grant Options to eligible persons and
will determine whether such Options will be Incentive Stock Options within the
meaning of the Code ("ISO") or Nonqualified Stock Options ("NQSOS"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

           5.1   FORM OF OPTION GRANT.  Each Option granted under this Plan will
be evidenced by an Award Agreement which will expressly identify the Option as
an ISO or an NQSO ("STOCK OPTION AGREEMENT"), and will be in such form and
contain such provisions (which need not be the same for each Participant) as the
Committee may from time to time approve, and which will comply with and be
subject to the terms and conditions of this Plan.


                                         -2-
<PAGE>

           5.2   DATE OF GRANT.  The date of grant of an Option will be the date
on which the Committee makes the determination to grant such Option, unless
otherwise specified by the Committee.  The Stock Option Agreement and a copy of
this Plan will be delivered to the Participant within a reasonable time after
the granting of the Option.

           5.3   EXERCISE PERIOD.  Options may be exercisable within the times
or upon the events determined by the Committee as set forth in the Stock Option
Agreement governing such Option; PROVIDED, HOWEVER, that no Option will be
exercisable after the expiration of ten (10) years from the date the Option is
granted; and PROVIDED FURTHER that no ISO granted to a person who directly or by
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of any Parent or Subsidiary of the
Company ("TEN PERCENT STOCKHOLDER") will be exercisable after the expiration of
five (5) years from the date the ISO is granted.  The Committee also may provide
for Options to become exercisable at one time or from time to time, periodically
or otherwise, in such number of Shares or percentage of Shares as the Committee
determines.

           5.4   EXERCISE PRICE.  The Exercise Price of an Option will be
determined by the Committee when the Option is granted and may be not less than
85% of the Fair Market Value of the Shares on the date of grant; provided that:
(i) the Exercise Price of an ISO will be not less than 100% of the Fair Market
Value of the Shares on the date of grant; and (ii) the Exercise Price of any ISO
granted to a Ten Percent Stockholder will not be less than 110% of the Fair
Market Value of the Shares on the date of grant.  Payment for the Shares
purchased may be made in accordance with Section 8 of this Plan.

           5.5   METHOD OF EXERCISE.  Options may be exercised only by delivery
to the Company of a written stock option exercise agreement  (the
"EXERCISE AGREEMENT") in a form approved by the Committee (which need not be the
same for each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable by the Company to comply with applicable securities laws, together
with payment in full of the Exercise Price for the number of Shares being
purchased.

           5.6   TERMINATION.  Notwithstanding the exercise periods set forth in
the Stock Option Agreement, exercise of an Option will always be subject to the
following:

     (a)   If the Participant is Terminated for any reason except death or
           Disability, then the Participant may exercise such Participant's
           Options only to the extent that such Options would have been
           exercisable upon the Termination Date no later than three (3) months
           after the Termination Date (or such shorter or longer time period not
           exceeding five (5) years as may be determined by the Committee, with
           any exercise beyond three (3) months after the Termination Date
           deemed to be an NQSO), but in any event, no later than the expiration
           date of the Options.

     (b)   If the Participant is Terminated because of Participant's death or
           Disability (or the Participant dies within three (3) months after a
           Termination other than for Cause or because of Participant's
           Disability), then Participant's Options may be exercised only to the
           extent that such Options would have been exercisable by Participant
           on the Termination Date and must be exercised by Participant (or
           Participant's legal representative or authorized assignee) no later
           than twelve (12) months after the Termination Date (or such shorter
           or longer time period not exceeding five (5) years as may be
           determined by the Committee, with any such exercise beyond (a) three
           (3) months after the Termination Date when the Termination is for any
           reason other than the Participant's death or Disability, or (b)
           twelve (12) months after the Termination Date when the Termination is
           for Participant's death or Disability, deemed to be an NQSO), but in
           any event no later than the expiration date of the Options.


                                         -3-

     (c)   Notwithstanding the provisions in paragraph 5.6(a) above, if a
           Participant is terminated for Cause, neither the Participant, the
           Participant's estate nor such other person who may then hold the
           Option shall be entitled to exercise any Option with respect to any
           Shares whatsoever, after termination of service, whether or not after
           termination of service the Participant may receive payment from the
           Company or Subsidiary for vacation pay, for services rendered prior
           to termination, for services rendered for the day on which
           termination occurs, for salary in lieu of notice, or for any other
           benefits.  In making such determination, the Board shall give the
           Participant an opportunity to present to the Board evidence on his
           behalf.  For the purpose of this paragraph, termination of service
           shall be deemed to occur on the date when the Company dispatches
           notice or advice to the Participant that his service is terminated.

           5.7   LIMITATIONS ON EXERCISE.  The Committee may specify a
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

           5.8   LIMITATIONS ON ISO.  The aggregate Fair Market Value
(determined as of the date of grant) of Shares with respect to which ISO are
exercisable for the first time by a Participant during any calendar year (under
this Plan or under any other incentive stock option plan of the Company, Parent
or Subsidiary of the Company) will not exceed $100,000.  If the Fair Market
Value of Shares on the date of grant with respect to which ISO are exercisable
for the first time by a Participant during any calendar year exceeds $100,000,
then the Options for the first $100,000 worth of Shares to become exercisable in
such calendar year will be ISO and the Options for the amount in excess of
$100,000 that become exercisable in that calendar year will be NQSOs.  In the
event that the Code or the regulations promulgated thereunder are amended after
the Effective Date of this Plan to provide for a different limit on the Fair
Market Value of Shares permitted to be subject to ISO, such different limit will
be automatically incorporated herein and will apply to any Options granted after
the effective date of such amendment.

           5.9   MODIFICATION, EXTENSION OR RENEWAL.  The Committee may modify,
extend or renew outstanding Options and authorize the grant of new Options in
substitution therefor, provided that any such action may not, without the
written consent of a Participant, impair any of such Participant's rights under
any Option previously granted.  Any outstanding ISO that is modified, extended,
renewed or otherwise altered will be treated in accordance with Section 424(h)
of the Code.  The Committee may reduce the Exercise Price of outstanding Options
without the consent of Participants affected by a written notice to them;
PROVIDED, HOWEVER, that the Exercise Price may not be reduced below the minimum
Exercise Price that would be permitted under Section 5.4 of this Plan for
Options granted on the date the action is taken to reduce the Exercise Price.

           5.10  NO DISQUALIFICATION.  Notwithstanding any other provision in
this Plan, no term of this Plan relating to ISO will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

     6.    RESTRICTED STOCK.  A Restricted Stock Award is an offer by the
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee will determine to whom an offer will be made, the number of Shares
the person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

           6.1   FORM OF RESTRICTED STOCK AWARD.  All purchases under a
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time approve, and will comply with and be subject to the terms and
conditions of this Plan.  The offer of Restricted Stock will be accepted by the
Participant's execution and delivery of the Restricted Stock Purchase Agreement
and full payment for the Shares to the Company within thirty (30) days from the
date the Restricted Stock Purchase Agree-


                                         -4-
<PAGE>

ment is delivered to the person.  If such person does not execute and deliver
the Restricted Stock Purchase Agreement along with full payment for the Shares
to the Company within thirty (30) days, then the offer will terminate, unless
otherwise determined by the Committee.

           6.2   PURCHASE PRICE.  The Purchase Price of Shares sold pursuant to
a Restricted Stock Award will be determined by the Committee on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Stockholder, in which case the Purchase Price will be 100% of the Fair Market
Value.  Payment of the Purchase Price may be made in accordance with Section 8
of this Plan.

           6.3   TERMS OF RESTRICTED STOCK AWARDS.  Restricted Stock Awards
shall be subject to such restrictions as the Committee may impose.  These
restrictions may be based upon completion of a specified number of years of
service with the Company or upon completion of the performance goals as set out
in advance in the Participant's individual Restricted Stock Purchase Agreement.
Restricted Stock Awards may vary from Participant to Participant and between
groups of Participants.  Prior to the grant of a Restricted Stock Award, the
Committee shall:  (a) determine the nature, length and starting date of any
Performance Period for the Restricted Stock Award; (b) select from among the
Performance Factors to be used to measure performance goals, if any; and (c)
determine the number of Shares that may be awarded to the Participant.  Prior to
the payment of any Restricted Stock Award, the Committee shall determine the
extent to which such Restricted Stock Award has been earned.  Performance
Periods may overlap and Participants may participate simultaneously with respect
to Restricted Stock Awards that are subject to different Performance Periods and
having different performance goals and other criteria.

           6.4   TERMINATION DURING PERFORMANCE PERIOD.  If a Participant is
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Restricted Stock Award only to the extent earned as of the date of
Termination in accordance with the Restricted Stock Purchase Agreement, unless
the Committee will determine otherwise.

     7.    STOCK BONUSES.

           7.1   AWARDS OF STOCK BONUSES.  A Stock Bonus is an award of Shares
(which may consist of Restricted Stock) for services rendered to the Company or
any Parent or Subsidiary of the Company.  A Stock Bonus may be awarded for past
services already rendered to the Company, or any Parent or Subsidiary of the
Company pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that will
be in such form (which need not be the same for each Participant) as the
Committee will from time to time approve, and will comply with and be subject to
the terms and conditions of this Plan.  A Stock Bonus may be awarded upon
satisfaction of such performance goals as are set out in advance in the
Participant's individual Award Agreement (the "PERFORMANCE STOCK BONUS
AGREEMENT") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan.  Stock Bonuses may
vary from Participant to Participant and between groups of Participants, and may
be based upon the achievement of the Company, Parent or Subsidiary and/or
individual performance factors or upon such other criteria as the Committee may
determine.

           7.2   TERMS OF STOCK BONUSES.  The Committee will determine the
number of Shares to be awarded to the Participant.  If the Stock Bonus is being
earned upon the satisfaction of performance goals pursuant to a Performance
Stock Bonus Agreement, then the Committee will: (a)  determine the nature,
length and starting date of any Performance Period for each Stock Bonus; (b)
select from among the Performance Factors to be used to measure the performance,
if any; and (c) determine the number of Shares that may be awarded to the
Participant.  Prior to the payment of any Stock Bonus, the Committee shall
determine the extent to which such Stock Bonuses have been earned.  Performance
Periods may overlap and Participants may participate simultaneously with respect
to Stock Bonuses that are subject to different Performance Periods and different
performance goals and other criteria.  The number of Shares may be fixed or may
vary in accordance with such performance goals and criteria as may be determined
by the Committee.  The Committee may adjust the performance goals applicable to
the Stock Bonuses to take into account changes in law and accounting or tax
rules and to make such adjustments as


                                         -5-
<PAGE>

the Committee deems necessary or appropriate to reflect the impact of
extraordinary or unusual items, events or circumstances to avoid windfalls or
hardships.

           7.3   FORM OF PAYMENT.  The earned portion of a Stock Bonus may be
paid currently or on a deferred basis with such interest or dividend equivalent,
if any, as the Committee may determine.  Payment may be made in the form of cash
or whole Shares or a combination thereof, either in a lump sum payment or in
installments, all as the Committee will determine.

     8.    PAYMENT FOR SHARE PURCHASES.

           8.1   PAYMENT.  Payment for Shares purchased pursuant to this Plan
may be made in cash (by check) or, where expressly approved for the Participant
by the Committee and where permitted by law:

     (a)   by cancellation of indebtedness of the Company to the Participant;

     (b)   by surrender of shares that either:  (1) have been owned by
           Participant for more than six (6) months and have been paid for
           within the meaning of SEC Rule 144 (and, if such shares were
           purchased from the Company by use of a promissory note, such note has
           been fully paid with respect to such shares); or (2) were obtained by
           Participant in the public market;

     (c)   by tender of a full recourse promissory note having such terms as may
           be approved by the Committee and bearing interest at a rate
           sufficient to avoid imputation of income under Sections 483 and 1274
           of the Code; PROVIDED, HOWEVER, that Participants who are not
           employees or directors of the Company will not be entitled to
           purchase Shares with a promissory note unless the note is adequately
           secured by collateral other than the Shares;

     (d)   by waiver of compensation due or accrued to the Participant for
           services rendered;

     (e)   with respect only to purchases upon exercise of an Option, and
           provided that a public market for the Company's stock exists:

           (1)   through a "same day sale" commitment from the Participant and a
                 broker-dealer that is a member of the National Association of
                 Securities Dealers (an "NASD DEALER") whereby the Participant
                 irrevocably elects to exercise the Option and to sell a portion
                 of the Shares so purchased to pay for the Exercise Price, and
                 whereby the NASD Dealer irrevocably commits upon receipt of
                 such Shares to forward the Exercise Price directly to the
                 Company; or

           (2)   through a "margin" commitment from the Participant and a NASD
                 Dealer whereby the Participant irrevocably elects to exercise
                 the Option and to pledge the Shares so purchased to the NASD
                 Dealer in a margin account as security for a loan from the NASD
                 Dealer in the amount of the Exercise Price, and whereby the
                 NASD Dealer irrevocably commits upon receipt of such Shares to
                 forward the Exercise Price directly to the Company; or

     (f)   by any combination of the foregoing.

           8.2   LOAN GUARANTEES.  The Committee may help the Participant pay
for Shares purchased under this Plan by authorizing a guarantee by the Company
of a third-party loan to the Participant.


                                         -6-
<PAGE>

     9.    WITHHOLDING TAXES.

           9.1   WITHHOLDING GENERALLY.  Whenever Shares are to be issued in
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares.  Whenever, under this Plan,
payments in satisfaction of Awards are to be made in cash, such payment will be
net of an amount sufficient to satisfy federal, state, and local withholding tax
requirements.

           9.2   STOCK WITHHOLDING.  When, under applicable tax laws, a
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined.  All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee

     10.   PRIVILEGES OF STOCK OWNERSHIP.

           10.1  VOTING AND DIVIDENDS.  No Participant will have any of the
rights of a stockholder with respect to any Shares until the Shares are issued
to the Participant.  After Shares are issued to the Participant, the Participant
will be a stockholder and have all the rights of a stockholder with respect to
such Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; PROVIDED, that if such
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; PROVIDED, FURTHER, that the Participant will have no right to
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's Purchase Price or Exercise Price pursuant
to Section 12.

           10.2  FINANCIAL STATEMENTS.  The Company will provide financial
statements to each Participant prior to such Participant's purchase of Shares
under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding; PROVIDED, HOWEVER, the Company will not be
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

     11.   TRANSFERABILITY.  Awards granted under this Plan, and any interest
therein, will not be transferable or assignable by Participant, and may not be
made subject to execution, attachment or similar process, otherwise than by will
or by the laws of descent and distribution or as determined by the Committee and
set forth in the Award Agreement with respect to Awards that are not ISOs.
During the lifetime of the Participant an Award will be exercisable only by the
Participant, and any elections with respect to an Award may be made only by the
Participant unless otherwise determined by the Committee and set forth in the
Award Agreement with respect to Awards that are not ISOs.

     12.   RESTRICTIONS ON SHARES.  At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under this Plan, for cash and/or cancellation of purchase money
indebtedness, at the Participant's Exercise Price or Purchase Price, as the case
may be.

     13.   CERTIFICATES.  All certificates for Shares or other securities
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or


                                         -7-
<PAGE>

advisable, including restrictions under any applicable federal, state or foreign
securities law, or any rules, regulations and other requirements of the SEC or
any stock exchange or automated quotation system upon which the Shares may be
listed or quoted.

     14.   ESCROW; PLEDGE OF SHARES.  To enforce any restrictions on a
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates.  Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure the payment of Participant's obligation to the
Company under the promissory note; PROVIDED, HOWEVER, that the Committee may
require or accept other or additional forms of collateral to secure the payment
of such obligation and, in any event, the Company will have full recourse
against the Participant under the promissory note notwithstanding any pledge of
the Participant's Shares or other collateral.  In connection with any pledge of
the Shares, Participant will be required to execute and deliver a written pledge
agreement in such form as the Committee will from time to time approve.  The
Shares purchased with the promissory note may be released from the pledge on a
pro rata basis as the promissory note is paid.

     15.   EXCHANGE AND BUYOUT OF AWARDS.  The Committee may, at any time or
from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards.  The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

     16.   SECURITIES LAW AND OTHER REGULATORY COMPLIANCE.  An Award will not be
effective unless such Award is in compliance with all applicable federal and
state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed or quoted, as they are in effect on the date of grant
of the Award and also on the date of exercise or other issuance.
Notwithstanding any other provision in this Plan, the Company will have no
obligation to issue or deliver certificates for Shares under this Plan prior to:
(a) obtaining any approvals from governmental agencies that the Company
determines are necessary or advisable; and/or (b) completion of any registration
or other qualification of such Shares under any state or federal law or ruling
of any governmental body that the Company determines to be necessary or
advisable.  The Company will be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or automated quotation
system, and the Company will have no liability for any inability or failure to
do so.

     17.   NO OBLIGATION TO EMPLOY.  Nothing in this Plan or any Award granted
under this Plan will confer or be deemed to confer on any Participant any right
to continue in the employ of, or to continue any other relationship with, the
Company or any Parent or Subsidiary of the Company or limit in any way the right
of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

     18.   CORPORATE TRANSACTIONS.

           18.1  ASSUMPTION OR REPLACEMENT OF AWARDS BY SUCCESSOR.  In the event
of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company immediately prior to


                                         -8-
<PAGE>

such merger (other than any stockholder that merges, or which owns or controls
another corporation that merges, with the Company in such merger) cease to own
their shares or other equity interest in the Company, (d) the sale of
substantially all of the assets of the Company, or (e) the acquisition, sale, or
transfer of more than 50% of the outstanding shares of the Company by tender
offer or similar transaction, any or all outstanding Awards may be assumed,
converted or replaced by the successor corporation (if any), which assumption,
conversion or replacement will be binding on all Participants.  In the
alternative, the successor corporation may substitute equivalent Awards or
provide substantially similar consideration to Participants as was provided to
stockholders (after taking into account the existing provisions of the Awards).
The successor corporation may also issue, in place of outstanding Shares of the
Company held by the Participant, substantially similar shares or other property
subject to repurchase restrictions no less favorable to the Participant.  In the
event such successor corporation (if any) refuses to assume or substitute
Awards, as provided above, pursuant to a transaction described in this
Subsection 18.1, such Awards will expire on such transaction at such time and on
such conditions as the Committee will determine.  Notwithstanding anything in
this Plan to the contrary, the Committee may, in its sole discretion, provide
that the vesting of any or all Awards granted pursuant to this Plan will
accelerate upon a transaction described in this Section 18.  If the Committee
exercises such discretion with respect to Options, such Options will become
exercisable in full prior to the consummation of such event at such time and on
such conditions as the Committee determines, and if such Options are not
exercised prior to the consummation of the corporate transaction, they shall
terminate at such time as determined by the Committee.

           18.2  OTHER TREATMENT OF AWARDS.  Subject to any greater rights
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, or sale of assets.

           18.3  ASSUMPTION OF AWARDS BY THE COMPANY.  The Company, from time to
time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either; (a) granting an Award under this Plan in substitution of
such other company's award; or (b) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan.  Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant.  In the event the Company assumes an award granted by
another company, the terms and conditions of such award will remain unchanged
(EXCEPT that the exercise price and the number and nature of Shares issuable
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code).  In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

     19.   ADOPTION AND STOCKHOLDER APPROVAL.  This Plan will become effective
on the date on which the registration statement filed by the Company with the
SEC under the Securities Act registering the initial public offering of the
Company's Common Stock is declared effective by the SEC (the "EFFECTIVE DATE").
This Plan shall be approved by the stockholders of the Company (excluding Shares
issued pursuant to this Plan), consistent with applicable laws, within twelve
(12) months before or after the date this Plan is adopted by the Board.  Upon
the Effective Date, the Committee may grant Awards pursuant to this Plan;
PROVIDED, HOWEVER, that: (a) no Option may be exercised prior to initial
stockholder approval of this Plan; (b) no Option granted pursuant to an increase
in the number of Shares subject to this Plan approved by the Board will be
exercised prior to the time such increase has been approved by the stockholders
of the Company; (c) in the event that initial stockholder approval is not
obtained within the time period provided herein, all Awards granted hereunder
shall be cancelled, any Shares issued pursuant to any Awards shall be cancelled
and any purchase of Shares issued hereunder shall be rescinded; and (d) in the
event that stockholder approval of such increase is not obtained within the time
period provided herein, all Awards granted pursuant to such increase will be
cancelled, any Shares issued pursuant to any Award granted pursuant to such
increase will be cancelled, and any purchase of Shares pursuant to such increase
will be rescinded.

     20.   TERM OF PLAN/GOVERNING LAW.  Unless earlier terminated as provided
herein, this Plan will terminate ten (10) years from the date this Plan is
adopted by the Board or, if earlier, the date of stockholder approval.  This
Plan and all agreements thereunder shall be governed by and construed in
accordance with the laws of the State of California.

     21.   AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; PROVIDED, HOWEVER, that the Board will not, without the approval
of the stockholders of the Company, amend this Plan in any manner that requires
such stockholder approval.

     22.   NONEXCLUSIVITY OF THE PLAN.  Neither the adoption of this Plan by the
Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

                                   [ ] NONQUALIFIED STOCK OPTION

     1.   GRANT OF OPTION.  The Company hereby grants to Optionee an option
(this "OPTION") to purchase up to the total number of shares of Common Stock of
the Company set forth above as Total Option Shares (collectively, the "SHARES")
at the Exercise Price Per Share set forth above (the "EXERCISE PRICE"), subject
to all of the terms and conditions of this Agreement and the Plan.  If
designated as an Incentive Stock Option above, this Option is intended to
qualify as an "incentive stock option" ("ISO") within the meaning of Section 422
of the Internal Revenue Code of 1986, as amended (the "CODE"), to the extent
permitted under Code Section 422.

     2.   VESTING; EXERCISE PERIOD.

          2.1  VESTING OF SHARES.  This Option shall be exercisable as it vests.
Subject to the terms and conditions of the Plan and this Agreement, this Option
shall vest and become exercisable as to portions of the Shares as follows:
(a) this Option shall not be exercisable with respect to any of the Shares until
_________________, 19___ (the "First


<PAGE>

Vesting Date"); (b) if Optionee has continuously provided services to the
Company, or any Parent or Subsidiary of the Company, then on the First Vesting
Date, this Option shall become exercisable as to twenty-five percent (25%) of
the Shares; and (c) thereafter this Option shall become exercisable as to an
additional 2.08333% of the Shares on each monthly anniversary of the First
Vesting Date, provided that Optionee has continuously provided services to the
Company, or any Parent or Subsidiary of the Company, at all times during the
relevant month.   This Option shall cease to vest upon Optionee's Termination
and Optionee shall in no event be entitled under this Option to purchase a
number of shares of the Company's Common Stock greater than the "Total Option
Shares."

          2.2  VESTING OF OPTIONS.  Shares that are vested pursuant to the
schedule set forth in Section 2.1 hereof are "Vested Shares."  Shares that are
not vested pursuant to the schedule set forth in Section 2.1 hereof are
"Unvested Shares."

          2.3  EXPIRATION.  This Option shall expire on the Expiration Date set
forth above and must be exercised, if at all, on or before the earlier of the
Expiration Date or the date on which this Option is earlier terminated in
accordance with the provisions of Section 3 hereof.

     3.   TERMINATION.

          3.1  TERMINATION FOR ANY REASON EXCEPT DEATH, DISABILITY OR CAUSE.  If
Optionee is Terminated for any reason except Optionee's death, Disability or
Cause, then this Option, to the extent (and only to the extent) that it is
vested in accordance with the schedule set forth in Section 2.1 hereof on the
Termination Date, may be exercised by Optionee no later than three (3) months
after the Termination Date, but in any event no later than the Expiration Date.

          3.2  TERMINATION BECAUSE OF DEATH OR DISABILITY.  If Optionee is
Terminated because of death or Disability of Optionee (or the Optionee dies
within three (3) months after Termination other than for Cause or because of
Disability), then this Option, to the extent that it is vested in accordance
with the schedule set forth in Section 2.1 hereof on the Termination Date, may
be exercised by Optionee (or Optionee's legal representative or authorized
assignee) no later than twelve (12) months after the Termination Date, but in
any event no later than the Expiration Date.  Any exercise after three months
after the Termination Date when the Termination is for any reason other than
Optionee's death or disability, within the meaning of Code Section 22(e)(3),
shall be deemed to be the exercise of a nonqualified stock option.

          3.3  TERMINATION FOR CAUSE.  If Optionee is Terminated for Cause, this
Option will expire on the Optionee's date of Termination.

          3.4  NO OBLIGATION TO EMPLOY.  Nothing in the Plan or this Agreement
shall confer on Optionee any right to continue in the employ of, or other
relationship with, the Company or any Parent or Subsidiary of the Company, or
limit in any way the right of the Company or any Parent or Subsidiary of the
Company to terminate Optionee's employment or other relationship at any time,
with or without Cause.

     4.   MANNER OF EXERCISE.

          4.1  STOCK OPTION EXERCISE AGREEMENT.  To exercise this Option,
Optionee (or in the case of exercise after Optionee's death, Optionee's
executor, administrator, heir or legatee, as the case may be) must deliver to
the Company an executed stock option exercise agreement in the form attached
hereto as EXHIBIT A, or in such other form as may be approved by the Company
from time to time (the "EXERCISE AGREEMENT"), which shall set forth, INTER ALIA,
Optionee's election to exercise this Option, the number of shares being
purchased, any restrictions imposed on the Shares and any representations,
warranties and agreements regarding Optionee's investment intent and access to
information as may be required by the Company to comply with applicable
securities laws.  If someone other than Optionee exercises this Option, then
such person must submit documentation reasonably acceptable to the Company that
such person has the right to exercise this Option.

          4.2  LIMITATIONS ON EXERCISE.  This Option may not be exercised unless
such exercise is in compliance with all applicable federal and state securities
laws, as they are in effect on the date of exercise.  This Option may not be
exercised as to fewer than 100 Shares unless it is exercised as to all Shares as
to which this Option is then exercisable.

          4.3  PAYMENT.  The Exercise Agreement shall be accompanied by full
payment of the Exercise Price for the Shares being purchased in cash (by check),
or where permitted by law:

     (a)  by cancellation of indebtedness of the Company to the Optionee;

     (b)  by surrender of shares of the Company's Common Stock that either: (1)
          have been owned by Optionee for more than six (6) months and have been
          paid for within the meaning of SEC Rule 144 (and, if such shares were
          purchased from the Company by use of a promissory note, such note has
          been fully paid with respect to such shares); or (2) were obtained by
          Optionee in the open public market; AND (3) are clear of all liens,
          claims, encumbrances or security interests;

     (c)  by waiver of compensation due or accrued to Optionee for services
          rendered;

     (d)  provided that a public market for the Company's stock exists:  (1)
          through a "same day sale" commitment from Optionee and a broker-dealer
          that is a member of the National Association of Securities Dealers (an
          "NASD DEALER") whereby Optionee irrevocably elects to exercise this
          Option and to sell a portion of the Shares so purchased to pay for the
          Exercise Price and whereby the NASD Dealer irrevocably commits upon
          receipt of such Shares to forward the exercise price directly to the
          Company; OR (2) through a "margin" commitment from Optionee and an
          NASD Dealer whereby Optionee irrevocably elects to exercise this
          Option and to pledge the Shares so purchased to the NASD Dealer in a
          margin account as security for a loan from the NASD Dealer in the
          amount of the Exercise Price, and whereby


                                          3
<PAGE>

          the NASD Dealer irrevocably commits upon receipt of such Shares to
          forward the Exercise Price directly to the Company;

     (e)  by any combination of the foregoing.

               4.4  TAX WITHHOLDING.  Prior to the issuance of the Shares upon
exercise of this Option, Optionee must pay or provide for any applicable federal
or state withholding obligations of the Company.  If the Committee permits,
Optionee may provide for payment of withholding taxes upon exercise of this
Option by requesting that the Company retain Shares with a Fair Market Value
equal to the minimum amount of taxes required to be withheld.  In such case, the
Company shall issue the net number of Shares to the Optionee by deducting the
Shares retained from the Shares issuable upon exercise.

               4.5  ISSUANCE OF SHARES.  Provided that the Exercise Agreement
and payment are in form and substance satisfactory to counsel for the Company,
the Company shall issue the Shares registered in the name of Optionee,
Optionee's authorized assignee, or Optionee's legal representative, and shall
deliver certificates representing the Shares with the appropriate legends
affixed thereto.

          5.   NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  To the extent
this Option is an ISO, if Optionee sells or otherwise disposes of any of the
Shares acquired pursuant to the ISO on or before the later of (a) the date two
(2) years after the Date of Grant, and (b) the date one (1) year after transfer
of such Shares to Optionee upon exercise of this Option, then Optionee shall
immediately notify the Company in writing of such disposition.

          6.   COMPLIANCE WITH LAWS AND REGULATIONS.  The exercise of this
Option and the issuance and transfer of Shares shall be subject to compliance by
the Company and Optionee with all applicable requirements of federal and state
securities laws and with all applicable requirements of any stock exchange on
which the Company's Common Stock may be listed at the time of such issuance or
transfer.  Optionee understands that the Company is under no obligation to
register or qualify the Shares with the SEC, any state securities commission or
any stock exchange to effect such compliance.

          7.   NONTRANSFERABILITY OF OPTION.  This Option may not be transferred
in any manner other than by will or by the laws of descent and distribution and
may be exercised during the lifetime of Optionee only by Optionee.  The terms of
this Option shall be binding upon the executors, administrators, successors and
assigns of Optionee.

          8.   TAX CONSEQUENCES.  Set forth below is a brief summary as of the
date the Board adopted the Plan of some of the federal tax consequences of
exercise of this Option and disposition of the Shares.  THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
OPTIONEE SHOULD CONSULT A TAX ADVISOR BEFORE EXERCISING THIS OPTION OR DISPOSING
OF THE SHARES.

<PAGE>

               8.1  EXERCISE OF INCENTIVE STOCK OPTION.  To the extent this
Option qualifies as an ISO, there will be no regular federal income tax
liability upon the exercise of this Option, although the excess, if any, of the
fair market value of the Shares on the date of exercise over the Exercise Price
will be treated as a tax preference item for federal income tax purposes and may
subject the Optionee to the alternative minimum tax in the year of exercise.

               8.2  EXERCISE OF NONQUALIFIED STOCK OPTION.  To the extent this
Option does not qualify as an ISO, there may be a regular federal income tax
liability upon the exercise of this Option.  Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the fair market value of the Shares on the date of exercise
over the Exercise Price.  The Company may be required to withhold from
Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

               8.3  DISPOSITION OF SHARES.  The following tax consequences may
apply upon disposition of the Shares.

                    a.   INCENTIVE STOCK OPTIONS.  If the Shares are held for
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years
after the Date of Grant, any gain realized on disposition of the Shares will be
treated as capital gain for federal income tax purposes.  If Shares purchased
under an ISO are disposed of within the applicable one (1) year or two (2) year
period, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the excess, if any,
of the fair market value of the Shares on the date of exercise over the Exercise
Price.

                    b.   NONQUALIFIED STOCK OPTIONS.  If the Shares are held for
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an NQSO, any gain realized on disposition of the
Shares will be treated as long-term capital gain.

                    c.   WITHHOLDING.  The Company may be required to withhold
from Participant's compensation or collect from the Participant and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income.

          9.   PRIVILEGES OF STOCK OWNERSHIP.  Optionee shall not have any of
the rights of a stockholder with respect to any Shares until the Shares are
issued to Optionee.

          10.  INTERPRETATION.  Any dispute regarding the interpretation of this
Agreement shall be submitted by Optionee or the Company to the Committee for
review.  The resolution of such a dispute by the Committee shall be final and
binding on the Company and Optionee.

          11.  ENTIRE AGREEMENT.  The Plan is incorporated herein by reference.
This Agreement and the Plan and the Exercise Agreement constitute the entire
agreement and understanding of the parties hereto with respect to the subject
matter hereof and supersede all prior understandings and agreements with respect
to such subject matter.

          13.  SUCCESSORS AND ASSIGNS.  The Company may assign any of its rights
under this Agreement.  This Agreement shall be binding upon and inure to the
benefit of the successors and assigns of the Company.  Subject to the
restrictions on transfer set forth herein, this Agreement shall be binding upon
Optionee and Optionee's heirs, executors, administrators, legal representatives,
successors and assigns.

          14.  GOVERNING LAW.  This Agreement shall be governed by and construed
in accordance with the internal laws of the State of California, without regard
to that body of law pertaining to choice of law or conflict of law.

          15.  ACCEPTANCE.  Optionee hereby acknowledges receipt of a copy of
the Plan and this Agreement.  Optionee has read and understands the terms and
provisions thereof, and accepts this Option subject to all the terms and
conditions of the Plan and this Agreement.  Optionee acknowledges that there may

                                   ADFORCE, INC.
                                          
                          1999 DIRECTORS STOCK OPTION PLAN
                                          
                            As Adopted February 18, 1999


     1.    PURPOSE.  This 1999 Directors Stock Option Plan (this "PLAN") is
established to provide equity incentives for certain nonemployee members of the
Board of Directors of Adforce, Inc. (the "COMPANY"), who are described in
Section 6.1 below, by granting such persons options to purchase shares of stock
of the Company.

     2.    ADOPTION AND STOCKHOLDER APPROVAL.  After this Plan is adopted by the
Board of Directors of the Company (the "BOARD"), this Plan will become effective
on the time and date (the "EFFECTIVE DATE") on which the registration statement
filed by the Company with the Securities and Exchange Commission ("SEC") under
the Securities Act of 1933, as amended (the "SECURITIES ACT"), to register the
initial public offering of the Company's Common Stock is declared effective by
the SEC.  This Plan shall be approved by the stockholders of the Company,
consistent with applicable laws, within twelve (12) months after the date this
Plan is adopted by the Board.

     3.    TYPES OF OPTIONS AND SHARES.  Options granted under this Plan shall
be non-qualified stock options ("NQSOS").  The shares of stock that may be
purchased upon exercise of Options granted under this Plan (the "SHARES") are
shares of the Common Stock of the Company.

     4.    NUMBER OF SHARES.  The maximum number of Shares that may be issued
pursuant to Options granted under this Plan (the "MAXIMUM NUMBER") is 200,000
Shares, subject to adjustment as provided in this Plan.  If any Option is
terminated for any reason without being exercised in whole or in part, the
Shares thereby released from such Option shall be available for purchase under
other Options subsequently granted under this Plan.  At all times during the
term of this Plan, the Company shall reserve and keep available such number of
Shares as shall be required to satisfy the requirements of outstanding Options
granted under this Plan; provided, however that if the aggregate number of
Shares subject to outstanding Options granted under this Plan plus the aggregate
number of Shares previously issued by the Company pursuant to the exercise of
Options granted under this Plan equals or exceeds the Maximum Number, then
notwithstanding anything herein to the contrary, no further Options may be
granted under this Plan until the Maximum Number is increased or the aggregate
number of Shares subject to outstanding Options granted under this Plan plus the
aggregate number of Shares previously issued by the Company pursuant to the
exercise of Options granted under this Plan is less than the Maximum Number.

     5.    ADMINISTRATION.  This Plan shall be administered by the Board or by a
committee of not less than two members of the Board appointed to administer this
Plan (the "COMMITTEE").  As used in this Plan, references to the Committee shall
mean either such Committee or the Board if no Committee has been established. 
The interpretation by the Committee of any of the provisions of this Plan or any
Option granted under this Plan shall be final and binding upon the Company and
all persons having an interest in any Option or any Shares purchased pursuant to
an Option.

     6.    ELIGIBILITY AND AWARD FORMULA.

           6.1   ELIGIBILITY.  Options shall be granted only to directors of the
Company who are not employees of the Company or any Parent, Subsidiary or
Affiliate of the Company, as those terms are defined in Section 17 below (each
such person referred to as an "OPTIONEE"). 

           6.2   INITIAL GRANT.  Each Optionee who first becomes a member of the
Board on or after the Effective Date will automatically be granted an Option for
10,000 Shares (an "INITIAL GRANT") on the date such Optionee first becomes a
member of the Board.  Each Optionee who became a member of the Board prior to
the Effective Date will receive an Initial Grant immediately following the first
Annual Meeting of stockholders after the Effective Date.


<PAGE>

           6.3   SUCCEEDING GRANTS.  Immediately following each Annual Meeting
of stockholders, each Optionee will automatically be granted an Option for 5,000
Shares (a "SUCCEEDING GRANT"), provided the Optionee is a member of the Board on
such date and has served continuously as a member of the Board for a period of
at least one year since the date of such Optionee's Initial Grant.

     7.    TERMS AND CONDITIONS OF OPTIONS.  Subject to the following and to
Section 6 above:

           7.1   FORM OF OPTION GRANT.  Each Option granted under this Plan
shall be evidenced by a written Stock Option Grant ("GRANT") in such form (which
need not be the same for each Optionee) as the Committee shall from time to time
approve, which Grant shall comply with and be subject to the terms and
conditions of this Plan.

           7.2   VESTING.  The date an Optionee receives an Initial Grant or a
Succeeding Grant is referred to in this Plan as the "START DATE" for such
Option.

                 (a)   INITIAL GRANTS.  Each Initial Grant will vest as to
twenty-five percent (25%) of the Shares on the first anniversary of the Start
Date for such Initial Grant, and as to 2.08333% of the Shares on each subsequent
monthly anniversary of the Start Date, so long as the Optionee continuously
remains a director or a consultant of the Company.

                 (b)   SUCCEEDING GRANTS.  Each Succeeding Grant will vest as to
twenty-five percent (25%) of the Shares on the first anniversary of the Start
Date for such Succeeding Grant, and as to 2.08333% of the Shares on each
subsequent monthly anniversary of the Start Date, so long as the Optionee
continuously remains a director or a consultant of the Company.

           7.3   EXERCISE PRICE.  The exercise price of an Option shall be the
Fair Market Value (as defined in Section 17.4) of the Shares, at the time that
the Option is granted.

           7.4   TERMINATION OF OPTION.  Except as provided below in this
Section, each Option shall expire ten (10) years after its Start Date (the
"EXPIRATION DATE").  The Option shall cease to vest when the Optionee ceases to
be a member of the Board or a consultant of the Company.  The date on which the
Optionee ceases to be a member of the Board or a consultant of the Company shall
be referred to as the "TERMINATION DATE".  An Option may be exercised after the
Termination Date only as set forth below:

                 (a)   TERMINATION GENERALLY.  If the Optionee ceases to be a
member of the Board or a consultant of the Company for any reason except death
of the Optionee or disability of the Optionee (whether temporary or permanent,
partial or total, as determined by the Committee), then each Option then held by
such Optionee, to the extent (and only to the extent) that it would have been
exercisable by the Optionee on the Termination Date, may be exercised by the
Optionee no later than seven (7) months after the Termination Date, but in no
event later than the Expiration Date.

                 (b)   DEATH OR DISABILITY.  If the Optionee ceases to be a
member of the Board or a consultant of the Company because of the death of the
Optionee or the disability of the Optionee (whether temporary or permanent,
partial or total, as determined by the Committee), then each Option then held by
such Optionee to the extent (and only to the extent) that it would have been
exercisable by the Optionee on the Termination Date, may be exercised by the
Optionee (or the Optionee's legal representative) no later than twelve (12)
months after the Termination Date, but in no event later than the Expiration
Date.

     8.    EXERCISE OF OPTIONS.

           8.1   EXERCISE PERIOD.  Subject to the provisions of Section 8.5
below, Options shall be exercisable as they vest; provided that the Committee
may provide that such Options shall be immediately exercisable subject to
repurchase in accordance with the vesting schedule set forth in Section 7.

           8.2   NOTICE.  Options may be exercised only by delivery to the
Company of an exercise agreement in a form approved by the Committee stating the
number of Shares being purchased, the restrictions imposed on the Shares and
such representations and agreements regarding the Optionee's investment intent
and access to information as may be required by the Company to comply with
applicable securities laws, together with payment in full of the exercise price
for the number of Shares being purchased.

           8.3   PAYMENT.  Payment for the Shares purchased upon exercise of an
Option may be made (a) in cash or by check; (b) by surrender of shares of Common
Stock of the Company that have been owned by the Optionee for more than six (6)
months (and which have been paid for within the meaning of SEC Rule 144 and, if
such shares were purchased from the Company by use of a promissory note, such
note has been fully paid with respect to such shares) or were obtained by the
Optionee in the open public market, having a Fair Market Value equal to the
exercise price of the Option; (c) by waiver of compensation due or accrued to
the Optionee for services rendered; (d) provided that a public market for the
Company's stock exists, through a "same day sale" commitment from the Optionee
and a broker-dealer that is a member of the National Association of Securities
Dealers (an "NASD DEALER") whereby the Optionee irrevocably elects to exercise
the Option and to sell a portion of the Shares so purchased to pay for the
exercise price and whereby the NASD Dealer irrevocably commits upon receipt of
such Shares to forward the exercise price directly to the Company; (e) provided
that a public market for the Company's stock exists, through a "margin"
commitment from the Optionee and an NASD Dealer whereby the Optionee irrevocably
elects to exercise the Option and to pledge the Shares so purchased to the NASD
Dealer in a margin account as security for a loan from the NASD Dealer in the
amount of the exercise price, and whereby the NASD Dealer irrevocably commits
upon receipt of such Shares to forward the exercise price directly to the
Company; or (f) by any combination of the foregoing.

           8.4   WITHHOLDING TAXES.  Prior to issuance of the Shares upon
exercise of an Option, the Optionee shall pay or make adequate provision for any
federal or state withholding obligations of the Company, if applicable.

           8.5   LIMITATIONS ON EXERCISE.  Notwithstanding the exercise periods
set forth in the Grant, exercise of an Option shall always be subject to the
following limitations:

                 (a)   An Option shall not be exercisable unless such exercise
is in compliance with the Securities Act and all applicable state securities
laws, as they are in effect on the date of exercise.

                 (b)   The Committee may specify a reasonable minimum number of
Shares that may be purchased upon any exercise of an Option, provided that such
minimum number will not prevent the Optionee from exercising the full number of
Shares as to which the Option is then exercisable.

     9.    NONTRANSFERABILITY OF OPTIONS.  During the lifetime of the Optionee,
an Option shall be exercisable only by the Optionee or by the Optionee's
guardian or legal representative, unless otherwise determined by the Committee. 
No Option may be sold, pledged, assigned, hypothecated, transferred or disposed
of in any manner other than by will or by the laws of descent and distribution,
unless otherwise determined by the Committee.

     10.   PRIVILEGES OF STOCK OWNERSHIP.  No Optionee shall have any of the
rights of a stockholder with respect to any Shares subject to an Option until
the Option has been validly exercised.  No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior to
the date of exercise, except as provided in this Plan.  The Company shall
provide to each Optionee a copy of the annual financial statements of the


                                        - 3 -
<PAGE>

Company at such time after the close of each fiscal year of the Company as they
are released by the Company to its stockholders.

     11.   ADJUSTMENT OF OPTION SHARES.  In the event that the number of
outstanding shares of Common Stock of the Company is changed by a stock
dividend, stock split, reverse stock split, combination, reclassification or
similar change in the capital structure of the Company without consideration,
the number of Shares available under this Plan and the number of Shares subject
to outstanding Options and the exercise price per share of such outstanding
Options and, unless otherwise determined by the Committee, the number of shares
subject to Initial Grants and Succeeding Grants shall be proportionately
adjusted, subject to any required action by the Board or stockholders of the
Company and compliance with applicable securities laws; provided, however, that
no fractional shares shall be issued upon exercise of any Option and any
resulting fractions of a Share shall be rounded up to the nearest whole Share.

     12.   NO OBLIGATION TO CONTINUE AS DIRECTOR.  Nothing in this Plan or any
Option granted under this Plan shall confer on any Optionee any right to
continue as a director of the Company.

     13.   COMPLIANCE WITH LAWS.  The grant of Options and the issuance of
Shares upon exercise of any Options shall be subject to and conditioned upon
compliance with all applicable requirements of law, including without limitation
compliance with the Securities Act, compliance with all other applicable state
securities laws and compliance with the requirements of any stock exchange or
national market system on which the Shares may be listed.  The Company shall be
under no obligation to register the Shares with the SEC or to effect compliance
with the registration or qualification requirement of any state securities laws,
stock exchange or national market system.

     14.   ACCELERATION OF OPTIONS ON CERTAIN CORPORATE TRANSACTIONS.  In the
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Options granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption, conversion or
replacement will be binding on all Optionees), (c) a merger in which the Company
is the surviving corporation but after which the stockholders of the Company
(other than any stockholder which merges (or which owns or controls another
corporation which merges) with the Company in such merger) cease to own their
shares or other equity interests in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, the vesting of all options granted pursuant to this Plan
will accelerate and the options will become exercisable in full prior to the
consummation of such event at such times and on such conditions as the Committee
determines, and must be exercised, if at all, within seven months of the
consummation of said event.  Any options not exercised within such seven-month
period shall expire.

     15.   AMENDMENT OR TERMINATION OF PLAN.  The Board may at any time
terminate or amend this Plan or any outstanding option, provided that the Board
may not terminate or amend the terms of any outstanding option without the
consent of the Optionee.  In any case, no amendment of this Plan may adversely
affect any then outstanding Options or any unexercised portions thereof without
the written consent of the Optionee.

     16.   TERM OF PLAN.  Options may be granted pursuant to this Plan from time
to time within a period of ten (10) years from the Effective Date. 

     17.   CERTAIN DEFINITIONS.  As used in this Plan, the following terms shall
have the following meanings:

           17.1  "PARENT" means any corporation (other than the Company) in an
unbroken chain of corporations ending with the Company if each of such
corporations other than the Company owns stock possessing 50% or more of the
total combined voting power of all classes of stock in one of the other

           17.3  "AFFILIATE" means any corporation that directly, or indirectly

           17.4  "FAIR MARKET VALUE" means, as of any date, the value of a share

                 are initially offered for sale to the public by the Company's
                 underwriters in the initial public offering of the Company's
                 Common Stock pursuant to a registration statement filed with
                 the SEC under the Securities Act;  or
           
           (e)   if none of the foregoing is applicable, by the Committee in
                 good faith.

exercise of this Option, Optionee shall pay or make adequate provision for any
applicable federal or state withholding obligations of the Company.

          5.4  ISSUANCE OF SHARES.  Provided that such notice and payment are in
form and substance satisfactory to counsel for the Company, the Company shall

representative.  To enforce any restrictions on Optionee's Shares, the Committee
may require Optionee to deposit all certificates, together with stock powers or
other instruments of transfer approved by the Committee appropriately endorsed

Grant shall be submitted by Optionee or the Company to the Committee that
administers the Plan, which shall review such dispute at its next regular
meeting.  The resolution of such a dispute by the Committee shall be final and
binding on the Company and on Optionee.  Nothing in the Plan or this Grant shall
confer on Optionee any right to continue as a Board Member or to provide
services to the Company as a consultant.

     8.   ENTIRE AGREEMENT.  The Plan and the Directors Stock Option Exercise
Agreement in the form attached hereto as EXHIBIT A, and the terms and conditions
thereof, are incorporated herein by reference.  This Grant, the Plan and the
Directors Stock Option Exercise Agreement constitute the entire agreement and
understanding of the parties hereto with respect to the subject matter hereof

                            As Adopted February 18, 1999



     1.  ESTABLISHMENT OF PLAN.  Adforce, Inc. (the "COMPANY") proposes to grant
options for purchase of the Company's Common Stock to eligible employees of the
Company and its Participating Subsidiaries (as hereinafter defined) pursuant to
this Employee Stock Purchase Plan (this "PLAN").  For purposes of this Plan,
"PARENT CORPORATION" and "SUBSIDIARY" shall have the same meanings as "parent
corporation" and "subsidiary corporation" in Sections 424(e) and 424(f),
respectively, of the Internal Revenue Code of 1986, as amended (the "CODE"). 
"PARTICIPATING SUBSIDIARIES" are Parent Corporations or Subsidiaries that the
Board of Directors of the Company (the "BOARD") designates from time to time as
corporations that shall participate in this Plan.  The Company intends this Plan
to qualify as an "employee stock purchase plan" under Section 423 of the Code
(including any amendments to or replacements of such Section), and this Plan
shall be so construed.  Any term not expressly defined in this Plan but defined
for purposes of Section 423 of the Code shall have the same definition herein. 
A total of 300,000 shares of the Company's  Common Stock is reserved for
issuance under this Plan.  In addition, on each January 1, the aggregate number
of shares of the Company's Common Stock reserved for issuance under the Plan
shall be increased automatically by the number of shares purchased under this
Plan in the preceding calendar year; PROVIDED that the aggregate number of
shares issued over the term of this Plan shall not exceed 3,000,000 shares. 
Such number shall be subject to adjustments effected in accordance with Section
14 of this Plan.

     2.  PURPOSE.  The purpose of this Plan is to provide eligible employees of
the Company and Participating Subsidiaries with a convenient means of acquiring
an equity interest in the Company through payroll deductions, to enhance such
employees' sense of participation in the affairs of the Company and
Participating Subsidiaries, and to provide an incentive for continued
employment.

     3.  ADMINISTRATION.  This Plan shall be administered by the Compensation
Committee of the Board (the "COMMITTEE").  Subject to the provisions of this
Plan and the limitations of Section 423 of the Code or any successor provision
in the Code, all questions of interpretation or application of this Plan shall
be determined by the Committee and its decisions shall be final and binding upon
all participants.  Members of the Committee shall receive no compensation for
their services in connection with the administration of this Plan, other than
standard fees as established from time to time by the Board for services
rendered by Board members serving on Board committees.  All expenses incurred in
connection with the administration of this Plan shall be paid by the Company.

     4.  ELIGIBILITY.  Any employee of the Company or the Participating
Subsidiaries is eligible to participate in an Offering Period (as hereinafter
defined) under this Plan except the following:

         (a) employees who are not employed by the Company or a Participating
Subsidiary (10) days before the beginning of such Offering Period, except that
employees who are employed on the Effective Date of the Registration Statement
filed by the Company with the Securities and Exchange Commission ("SEC") under
the Securities Act of 1933, as amended (the "SECURITIES ACT") registering the
initial public offering of the Company's Common Stock shall be eligible to
participate in the first Offering Period under the Plan;

         (b) employees who are customarily employed for twenty (20) hours or
less per week;

         (c) employees who are customarily employed for five (5) months or less
in a calendar year;

         (d) employees who, together with any other person whose stock would be
attributed to such employee pursuant to Section 424(d) of the Code, own stock or
hold options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or any of
its Participating Subsidiaries or who, as a result of being granted an option
under this Plan with respect to such Offering Period, 
<PAGE>

would own stock or hold options to purchase stock possessing five percent (5%)
or more of the total combined voting power or value of all classes of stock of
the Company or any of its Participating Subsidiaries; and

         (e) individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors who are reclassified as
common law employees for any reason EXCEPT FOR federal income and employment tax
purposes.

     5.  OFFERING DATES.  The offering periods of this Plan (each, an "OFFERING
PERIOD") shall be of twenty-four (24) months duration commencing on February 1
and August 1 of each year and ending on January 31 and July 31 of each year;
PROVIDED, HOWEVER, that notwithstanding the foregoing, the first such Offering
Period shall commence on the first business day on which price quotations for
the Company's Common Stock are available on the Nasdaq National Market (the
"FIRST OFFERING DATE") and shall end on January 31, 2001.  Except for the first
Offering Period, each Offering Period shall consist of four (4) six month
purchase periods (individually, a "PURCHASE PERIOD") during which payroll
deductions of the participants are accumulated under this Plan.  The first
Offering Period shall consist of no more than five and no fewer than three
Purchase Periods, any of which may be greater or less than six months as
determined by the Committee.  The first business day of each Offering Period is
referred to as the "OFFERING DATE".  The last business day of each Purchase
Period is referred to as the "PURCHASE DATE".  The Committee shall have the
power to change the duration of Offering Periods with respect to offerings
without stockholder approval if such change is announced at least fifteen (15)
days prior to the scheduled beginning of the first Offering Period to be
affected. 

     6.  PARTICIPATION IN THIS PLAN.  Eligible employees may become participants
in an Offering Period under this Plan on the first Offering Date after
satisfying the eligibility requirements by delivering a subscription agreement
to the Company's treasury department (the "TREASURY DEPARTMENT") not later than
five (5) days before such Offering Date.  Notwithstanding the foregoing, the
Committee may set a later time for filing the subscription agreement authorizing
payroll deductions for all eligible employees with respect to a given Offering
Period.  An eligible employee who does not deliver a subscription agreement to
the Treasury Department by such date after becoming eligible to participate in
such Offering Period shall not participate in that Offering Period or any
subsequent Offering Period unless such employee enrolls in this Plan by filing a
subscription agreement with the Treasury Department not later than five (5) days
preceding a subsequent Offering Date.  Once an employee becomes a participant in
an Offering Period, such employee will automatically participate in the Offering
Period commencing immediately following the last day of the prior Offering
Period unless the employee withdraws or is deemed to withdraw from this Plan or
terminates further participation in the Offering Period as set forth in Section
11 below.  Such participant is not required to file any additional subscription
agreement in order to continue participation in this Plan.  

     7.  GRANT OF OPTION ON ENROLLMENT.  Enrollment by an eligible employee in
this Plan with respect to an Offering Period will constitute the grant (as of
the Offering Date) by the Company to such employee of an option to purchase on
the Purchase Date up to that number of shares of Common Stock of the Company
determined by dividing (a) the amount accumulated in such employee's payroll
deduction account during such Purchase Period by (b) the lower of
(i) eighty-five percent (85%) of the fair market value of a share of the
Company's Common Stock on the Offering Date (but in no event less than the par
value of a share of the Company's Common Stock), or (ii) eighty-five percent
(85%) of the fair market value of a share of the Company's Common Stock on the
Purchase Date (but in no event less than the par value of a share of the
Company's Common Stock), PROVIDED, HOWEVER, that the number of shares of the
Company's Common Stock subject to any option granted pursuant to this Plan
shall not exceed the lesser of (x) the maximum number of shares set by the
Committee pursuant to Section 10(c) below with respect to the applicable
Purchase Date, or (y) the maximum number of shares which may be purchased
pursuant to Section 10(b) below with respect to the applicable Purchase Date. 
The fair market value of a share of the Company's Common Stock shall be
determined as provided in Section 8 below.

     8.  PURCHASE PRICE.  The purchase price per share at which a share of 
Common Stock will be sold in any Offering Period shall be eighty-five percent
(85%) of the lesser of:

         (a) The fair market value on the Offering Date; or


                                        - 2 -
<PAGE>

         (b) The fair market value on the Purchase Date.

     For purposes of this Plan, the term "FAIR MARKET VALUE" means, as of any
date, the value of a share of the Company's Common Stock determined as follows:

          (a)  if such Common Stock is then quoted on the Nasdaq National
               Market, its closing price on the Nasdaq National Market on the
               date of determination as reported in THE WALL STREET JOURNAL;

          (b)  if such Common Stock is publicly traded and is then listed on a
               national securities exchange, its closing price on the date of
               determination on the principal national securities exchange on
               which the Common Stock is listed or admitted to trading as
               reported in THE WALL STREET JOURNAL;

          (c)  if such Common Stock is publicly traded but is not quoted on the
               Nasdaq National Market nor listed or admitted to trading on a
               national securities exchange, the average of the closing bid and
               asked prices on the date of determination as reported in THE WALL
               STREET JOURNAL; or

          (d)  if none of the foregoing is applicable, by the Board in good
               faith, which in the case of the First Offering Date will be the
               price per share at which shares of the Company's Common Stock
               are initially offered for sale to the public by the Company's
               underwriters in the initial public offering of the Company's 
               Common Stock pursuant to a registration statement filed with the
               SEC under the Securities Act.

     9.  PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF
SHARES.  

     (a)  The purchase price of the shares is accumulated by regular payroll
deductions made during each Offering Period.  The deductions are made as a
percentage of the participant's compensation in one percent (1%) increments not
less than two percent (2%), nor greater than ten percent (10%) or such lower
limit set by the Committee.  Compensation shall mean all W-2 cash compensation,
including, but not limited to, base salary, wages, commissions, overtime, shift
premiums and bonuses, plus draws against commissions, PROVIDED, HOWEVER, that
for purposes of determining a participant's compensation, any election by such
participant to reduce his or her regular cash remuneration under Sections 125 or
401(k) of the Code shall be treated as if the participant did not make such
election.  Payroll deductions shall commence on the first payday of the Offering
Period and shall continue to the end of the Offering Period unless sooner
altered or terminated as provided in this Plan.

     (b)  A participant may increase or decrease the rate of payroll deductions
during an Offering Period by filing with the Treasury Department a new
authorization for payroll deductions, in which case the new rate shall become
effective for the next payroll period commencing more than fifteen (15) days
after the Treasury Department's receipt of the authorization and shall continue
for the remainder of the Offering Period unless changed as described below. 
Such change in the rate of payroll deductions may be made at any time during an
Offering Period, but not more than one (1) change may be made effective during
any Purchase Period.  A participant may increase or decrease the rate of payroll
deductions for any subsequent Offering Period by filing with the Treasury
Department a new authorization for payroll deductions not later than fifteen
(15) days before the beginning of such Offering Period.

     (c)  A participant may reduce his or her payroll deduction percentage to
zero during an Offering Period by filing with the Treasury Department a request
for cessation of payroll deductions.  Such reduction shall be effective
beginning with the next payroll period commencing more than fifteen (15) days
after the Treasury Department's receipt of the request and no further payroll
deductions will be made for the duration of the Offering Period.  Payroll
deductions credited to the participant's account prior to the effective date of
the request shall be used to purchase shares of Common Stock of the Company in
accordance with Section (e) below.  A participant may not resume making payroll
deductions during the Offering Period in which he or she reduced his or her
payroll deductions to zero.


                                        - 3 -
<PAGE>

     (d)  All payroll deductions made for a participant are credited to his or
her account under this Plan and are deposited with the general funds of the
Company.  No interest accrues on the payroll deductions.  All payroll deductions
received or held by the Company may be used by the Company for any corporate
purpose, and the Company shall not be obligated to segregate such payroll
deductions.

     (e)  On each Purchase Date, so long as this Plan remains in effect and
provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company that the participant
wishes to withdraw from that Offering Period under this Plan and have all
payroll deductions accumulated in the account maintained on behalf of the
participant as of that date returned to the participant, the Company shall apply
the funds then in the participant's account to the purchase of whole shares of 
Common Stock reserved under the option granted to such participant with respect
to the Offering Period to the extent that such option is exercisable on the
Purchase Date.  The purchase price per share shall be as specified in Section 8
of this Plan.  Any cash remaining in a participant's account after such purchase
of shares shall be refunded to such participant in cash, without interest;
provided, however that any amount remaining in such participant's account on a
Purchase Date which is less than the amount necessary to purchase a full share
of Common Stock of the Company shall be carried forward, without interest, into
the next Purchase Period or Offering Period, as the case may be.  In the event
that this Plan has been oversubscribed, all funds not used to purchase shares on
the Purchase Date shall be returned to the participant, without interest.  No 
Common Stock shall be purchased on a Purchase Date on behalf of any employee
whose participation in this Plan has terminated prior to such Purchase Date.

     (f)  As promptly as practicable after the Purchase Date, the Company shall
issue shares for the participant's benefit representing the shares purchased
upon exercise of his or her option.

     (g)  During a participant's lifetime, his or her option to purchase shares
hereunder is exercisable only by him or her.  The participant will have no
interest or voting right in shares covered by his or her option until such
option has been exercised. 

     10.  LIMITATIONS ON SHARES TO BE PURCHASED.  

     (a)  No participant shall be entitled to purchase stock under this Plan at
a rate which, when aggregated with his or her rights to purchase stock under all
other employee stock purchase plans of the Company or any Subsidiary, exceeds
$25,000 in fair market value, determined as of the Offering Date (or such other
limit as may be imposed by the Code) for each calendar year in which the
employee participates in this Plan.  The Company shall automatically suspend the
payroll deductions of any participant as necessary to enforce such limit
provided that when the Company automatically resumes such payroll deductions,
the Company must apply the rate in effect immediately prior to such suspension.

     (b)  No more than two hundred percent (200%) of the number of shares
determined by using eighty-five percent (85%) of the fair market value of a
share of the Company's  Common Stock on the Offering Date as the denominator may
be purchased by a participant on any single Purchase Date.

     (c)  No participant shall be entitled to purchase more than the Maximum
Share Amount (as defined below) on any single Purchase Date.  Not less than
thirty (30) days prior to the commencement of any Offering Period, the Committee
may, in its sole discretion, set a maximum number of shares which may be
purchased by any employee at any single Purchase Date (hereinafter the "MAXIMUM
SHARE AMOUNT").  Until otherwise determined by the Committee, there shall be no
Maximum Share Amount.  In no event shall the Maximum Share Amount exceed the
amounts permitted under Section 10(b) above.  If a new Maximum Share Amount is
set, then all participants must be notified of such Maximum Share Amount prior
to the commencement of the next Offering Period.  The Maximum Share Amount shall
continue to apply with respect to all succeeding Purchase Dates and Offering
Periods unless revised by the Committee as set forth above.

     (d)  If the number of shares to be purchased on a Purchase Date by all
employees participating in this Plan exceeds the number of shares then available
for issuance under this Plan, then the Company will make a pro rata allocation
of the remaining shares in as uniform a manner as shall be reasonably
practicable and as the Com-


                                        - 4 -
<PAGE>

mittee shall determine to be equitable.  In such event, the Company shall give
written notice of such reduction of the number of shares to be purchased under a
participant's option to each participant affected. 

     (e)  Any payroll deductions accumulated in a participant's account which
are not used to purchase stock due to the limitations in this Section 10 shall
be returned to the participant as soon as practicable after the end of the
applicable Purchase Period, without interest.

     11.  WITHDRAWAL.

     (a)  Each participant may withdraw from an Offering Period under this Plan
by signing and delivering to the Treasury Department a written notice to that
effect on a form provided for such purpose.  Such withdrawal may be elected at
any time at least fifteen (15) days prior to the end of an Offering Period.

     (b)  Upon withdrawal from this Plan, the accumulated payroll deductions
shall be returned to the withdrawn participant, without interest, and his or her
interest in this Plan shall terminate.  In the event a participant voluntarily
elects to withdraw from this Plan, he or she may not resume his or her
participation in this Plan during the same Offering Period, but he or she may
participate in any Offering Period under this Plan which commences on a date
subsequent to such withdrawal by filing a new authorization for payroll
deductions in the same manner as set forth in Section 6 above for initial
participation in this Plan.

     (c)  If the Fair Market Value on the first day of the current Offering
Period in which a participant is enrolled is higher than the Fair Market Value
on the first day of any subsequent Offering Period, the Company will
automatically enroll such participant in the subsequent Offering Period.  Any
funds accumulated in a participant's account prior to the first day of such
subsequent Offering Period will be applied to the purchase of shares on the
Purchase Date immediately prior to the first day of such subsequent Offering
Period, if any.

     12.  TERMINATION OF EMPLOYMENT.  Termination of a participant's employment
for any reason, including retirement, death or the failure of a participant to
remain an eligible employee of the Company or of a Participating Subsidiary,
immediately terminates his or her participation in this Plan.  In such event,
the payroll deductions credited to the participant's account will be returned to
him or her or, in the case of his or her death, to his or her legal
representative, without interest.  For purposes of this Section 12, an employee
will not be deemed to have terminated employment or failed to remain in the
continuous employ of the Company or of a Participating Subsidiary in the case of
sick leave, military leave, or any other leave of absence approved by the Board;
PROVIDED that such leave is for a period of not more than ninety (90) days or
reemployment upon the expiration of such leave is guaranteed by contract or
statute.

     13.  RETURN OF PAYROLL DEDUCTIONS.  In the event a participant's interest
in this Plan is terminated by withdrawal, termination of employment or
otherwise, or in the event this Plan is terminated by the Board, the Company
shall deliver to the participant all payroll deductions credited to such
participant's account.  No interest shall accrue on the payroll deductions of a
participant in this Plan.

     14.  CAPITAL CHANGES.  Subject to any required action by the stockholders
of the Company, the number of shares of  Common Stock covered by each option
under this Plan which has not yet been exercised and the number of shares of 
Common Stock which have been authorized for issuance under this Plan but have
not yet been placed under option (collectively, the "RESERVES"), as well as the
price per share of Common Stock covered by each option under this Plan which has
not yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued and outstanding shares of Common Stock of the
Company resulting from a stock split or the payment of a stock dividend (but
only on the Common Stock) or any other increase or decrease in the number of
issued and outstanding shares of Common Stock effected without receipt of any
consideration by the Company; PROVIDED, HOWEVER, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration".  Such adjustment shall be made by the
Committee, whose determination shall be final, binding and conclusive.  Except
as expressly provided herein, no issue by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of  Common Stock subject to an option.


                                        - 5 -
<PAGE>

     In the event of the proposed dissolution or liquidation of the Company, the
Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Committee.  The Committee may,
in the exercise of its sole discretion in such instances, declare that this Plan
shall terminate as of a date fixed by the Committee and give each participant
the right to purchase shares under this Plan prior to such termination.  In the
event of (i) a merger or consolidation in which the Company is not the surviving
corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders of
the Company or their relative stock holdings and the options under this Plan are
assumed, converted or replaced by the successor corporation, which assumption
will be binding on all participants), (ii) a merger in which the Company is the
surviving corporation but after which the stockholders of the Company
immediately prior to such merger (other than any stockholder that merges, or
which owns or controls another corporation that merges, with the Company in such
merger) cease to own their shares or other equity interest in the Company,
(iii) the sale of all or substantially all of the assets of the Company or (iv)
the acquisition, sale, or transfer of more than 50% of the outstanding shares of
the Company by tender offer or similar transaction, the Plan will continue with
regard to Offering Periods that commenced prior to the closing of the proposed
transaction and shares will be purchased based on the Fair Market Value of the
surviving corporation's stock on each Purchase Date, unless otherwise provided
by the Committee consistent with pooling of interests accounting treatment.

     The Committee may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding Common
Stock, or in the event of the Company being consolidated with or merged into any
other corporation.

     15.  NONASSIGNABILITY.  Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under this Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 22 below) by the participant.  Any such
attempt at assignment, transfer, pledge or other disposition shall be void and
without effect.

     16.  REPORTS.  Individual accounts will be maintained for each participant
in this Plan.  Each participant shall receive promptly after the end of each
Purchase Period a report of his or her account setting forth the total payroll
deductions accumulated, the number of shares purchased, the per share price
thereof and the remaining cash balance, if any, carried forward to the next
Purchase Period or Offering Period, as the case may be.

     17.  NOTICE OF DISPOSITION.  Each participant shall notify the Company in
writing if the participant disposes of any of the shares purchased in any
Offering Period pursuant to this Plan if such disposition occurs within two (2)
years from the Offering Date or within one (1) year from the Purchase Date on
which such shares were purchased (the "NOTICE PERIOD").  The Company may, at any
time during the Notice Period, place a legend or legends on any certificate
representing shares acquired pursuant to this Plan requesting the Company's
transfer agent to notify the Company of any transfer of the shares.  The
obligation of the participant to provide such notice shall continue
notwithstanding the placement of any such legend on the certificates.

     18.  NO RIGHTS TO CONTINUED EMPLOYMENT.  Neither this Plan nor the grant of
any option hereunder shall confer any right on any employee to remain in the
employ of the Company or any Participating Subsidiary, or restrict the right of
the Company or any Participating Subsidiary to terminate such employee's
employment.

     19.  EQUAL RIGHTS AND PRIVILEGES.  All eligible employees shall have equal
rights and privileges with respect to this Plan so that this Plan qualifies as
an "employee stock purchase plan" within the meaning of Section 423 or any
successor provision of the Code and the related regulations.  Any provision of
this Plan which is inconsistent with Section 423 or any successor provision of
the Code shall, without further act or amendment by the Company, the Committee
or the Board, be reformed to comply with the requirements of Section 423.  This
Section 19 shall take precedence over all other provisions in this Plan.

<PAGE>

     20.  NOTICES.  All notices or other communications by a participant to the
Company under or in connection with this Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     21.  TERM; STOCKHOLDER APPROVAL.  After this Plan is adopted by the Board,
this Plan will become effective on the First Offering Date (as defined above). 
This Plan shall be approved by the stockholders of the Company, in any manner
permitted by applicable corporate law, within twelve (12) months before or after
the date this Plan is adopted by the Board.  No purchase of shares pursuant to
this Plan shall occur prior to such stockholder approval.  This Plan shall
continue until the earlier to occur of (a) termination of this Plan by the Board
(which termination may be effected by the Board at any time), (b) issuance of
all of the shares of  Common Stock reserved for issuance under this Plan, or (c)
ten (10) years from the adoption of this Plan by the Board.

     22.  DESIGNATION OF BENEFICIARY.  

     (a)  A participant may file a written designation of a beneficiary who is
to receive any shares and cash, if any, from the participant's account under
this Plan in the event of such participant's death subsequent to the end of an
Purchase Period but prior to delivery to him of such shares and cash.  In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under this Plan in the event
of such participant's death prior to a Purchase Date.

     (b)  Such designation of beneficiary may be changed by the participant at
any time by written notice.  In the event of the death of a participant and in
the absence of a beneficiary validly designated under this Plan who is living at
the time of such participant's death, the Company shall deliver such shares or
cash to the executor or administrator of the estate of the participant, or if no
such executor or administrator has been appointed (to the knowledge of the
Company), the Company, in its discretion, may deliver such shares or cash to the
spouse or to any one or more dependents or relatives of the participant, or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

     23.  CONDITIONS UPON ISSUANCE OF SHARES; LIMITATION ON SALE OF SHARES. 
Shares shall not be issued with respect to an option unless the exercise of such
option and the issuance and delivery of such shares pursuant thereto shall
comply with all applicable provisions of law, domestic or foreign, including,
without limitation, the Securities Act, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange or automated quotation system upon which the shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

     24.  APPLICABLE LAW.  The Plan shall be governed by the substantive laws
(excluding the conflict of laws rules) of the State of California.

     25.  AMENDMENT OR TERMINATION OF THIS PLAN.  The Board may at any time
amend, terminate or extend the term of this Plan, except that any such
termination cannot affect options previously granted under this Plan, nor may
any amendment make any change in an option previously granted which would
adversely affect the right of any participant, nor may any amendment be made
without approval of the stockholders of the Company obtained in accordance with
Section 21 above within twelve (12) months of the adoption of such amendment (or
earlier if required by Section 21) if such amendment would:

     (a)  increase the number of shares that may be issued under this Plan; or

     (b)  change the designation of the employees (or class of employees)
eligible for participation in this Plan. 

     Notwithstanding the foregoing, the Board may make such amendments to the
Plan as the Board determines to be advisable, if the continuation of the Plan or
any Offering Period would result in financial accounting treatment for the Plan
that is different from the financial accounting treatment in effect on the date
this Plan is adopted by the Board.

                               SUBSCRIPTION AGREEMENT

1.   I elect to participate in the Adforce, Inc. (the "COMPANY") 1999 Employee
     Stock Purchase Plan (the "PLAN") and to subscribe to purchase shares of the
     Company's Common Stock (the "SHARES") in accordance with this Subscription
     Agreement and the Plan.

2.   I authorize payroll deductions from each of my paychecks in that percentage
     of my base salary, commissions, overtime, shift premiums, bonuses and draws
     against commissions as shown on my Enrollment Form, in accordance with the
     Plan.

3.   I understand that such payroll deductions shall be accumulated for the
     purchase of Shares under the Plan at the applicable purchase price
     determined in accordance with the Plan.  I further understand that except
     as otherwise set forth in the Plan, Shares will be purchased for me
     automatically at the end of each Purchase Period unless I withdraw from the
     Plan or otherwise become ineligible to participate in the Plan.

4.   I understand that this Subscription Agreement will automatically re-enroll
     me in all subsequent Offering Periods unless I withdraw from the Plan or I
     become ineligible to participate in the Plan.

5.   I acknowledge that I have a copy of and am familiar with the Company's most
     recent Prospectus which describes the Plan.  A copy of the complete Plan
     and the Prospectus is on file with the Company.  (In the case of the
     initial Plan Purchase Period, the Prospectus will be on file on the first
     day of the Offering Period.)

6.   I understand that Shares purchased for me under the Plan will be held in a
     personal account with the Plan Broker unless I request otherwise.

7.   I hereby agree to be bound by the terms of the Plan.  The effectiveness of
     this Subscription Agreement is dependent upon my eligibility to participate
     in the Plan.

8.   I have read and understood this Subscription Agreement.

    The term of this Lease shall be as shown in Item 7 of the Basic Lease
Provisions and shall commence on the Commencement Date set forth in Item 8
of the Basic Lease Provisions. Landlord shall deliver possession of the
Premises to Tenant upon execution of this Lease and Landlord's receipt of
Basic Annual Rental Upon Execution (set forth in Item 12 of the Basic Lease
Provisions), after which Tenant shall promptly commence and complete
Tenant's Work as provided in tile Work Letter attached as Exhibit "B" (the
"Possession Date"). From and after the Possession Date, Tenant shall
observe all obligations of the tenant pursuant to this Lease, except those
requiring the payment of Basic Annual Rent and Additional Rent. From and
after the Commencement Date, all provisions of the Lease shall be observed,
including those requiring the payment of Basic Annual Rent and Additional
Rent.

2.  BASIC ANNUAL RENT

    Tenant shall pay as Basic Annual Rent for the Premises the initial sum
shown in Item 4 of the Basic Lease Provisions, subject to adjustment as set
forth in Item 6 of the Basic Lease Provisions. The Basic Annual Rent shall
be payable in advance in equal monthly installments as shown in Item 5 of
the Basic Lease Provisions without deduction or offset, commencing on the
Commencement Date and continuing on the first day of each calendar month
thereafter. In the event the term of this Lease commences or ends on a day
other than the First or last day of a calendar month, or in the event
Basic Annual Rent Upon Execution covers only a portion of such Basic Annual
Rent for a calendar month, then the Basic Annual Rent for such partial
month shall be prorated in the proportion that the number of days this
Lease is in effect during such partial month bears to the number of days in
that calendar month, and such Basic Annual Rent shall be paid at tile
commencement or such partial month. The Basic Annual Rent Upon Execution
(set forth in Item 12 of the Basic Lease Provisions) shall be paid to
Landlord as provided in the Basic Lease Provisions.

3.  ADDITIONAL RENT

    (a) Tenant agrees to pay as Additional Rent for the Premises Tenant's
proportionate share of all "Building Operating Expenses" (as hereinafter
defined) and "Project Operating Expenses" (as hereinafter defined) incurred
by Landlord in the operation of the Building and the Project. Tenant's
proportionate share thereof (hereinafter, respectively, "Building Expense
Percentage" and "Project Expense Percentage") shall be the percentage
obtained by dividing the average Rentable Area of the Premises for such
year or portion thereof by ninety-five percent (95%) of the total Rentable
Area of the Building or the Project, as the case may be, for the same
period, and, subject to Exhibit "A-4," shall initially be as set forth in
Items 3.A. and 3.B. of the Basic Lease Provisions.


     (b) Prior to commencement of the Lease term and of each calendar year 
thereafter, Landlord shall give Tenant a written estimate of Building 
Operating Expenses and Project Operating Expenses and Tenant's proportionate 
shares thereof for the ensuing year or portion thereof. Tenant shall pay such 
estimated amount to Landlord in equal monthly installments, in advance. 
Within ninety (90) days after the end of each calendar year, Landlord shall 
furnish to Tenant a statement showing in reasonable detail the actual 
Building and Project Operating Expenses for such period in accordance with 
subparagraph (d) below, and the parties shall make any payment or allowance 
necessary to adjust Tenant's estimated payment to Tenant's proportionate 
share as shown by such annual statement. Any amount due from Tenant shall be 
paid within ten (10) days after receipt of such statement. Any amount due to 
Tenant shall be credited against installments of Additional Rent next comning 
due under this Paragraph 3 or if the Lease has terminated, such amount shall 
be paid by Landlord to Tenant within thirty (30) days of Tenant's receipt of 
the statement.

     (c) If at any time during any calendar year of the Lease term the
amount(s) and/or the rates for any item(s) of Operating Expenses for the
Building or the Project are increased to a rate(s) or amount(s) in excess
of the rate(s) or amount(s) used in calculating the estimated Building or
Project Operating Expenses for such calendar year, Tenant's estimated share
of such Building or Project Operating Expenses shall be increased for the
month in which such increase becomes effective and for succeeding months
by Tenant's Building Expense Percentage or Project Expense Percentage of
such increase, as applicable. In the event of such an increase in rate or
amount, Landlord shall give Tenant written notice (the "Adjustment
Notice") of the amount or estimated amount of increase, the month in
which effective, and Tenant's monthly share thereof. Commencing with
the first monthly payment of estimated Building Operating Expenses or
Project Operating Expenses, as applicable, required to be made by Tenant
after receipt of the Adjustment Notice (the "First Adjustment Payment"),
Tenant shall pay such increase to Landlord as part of Tenant's monthly
payments of estimated Building Operating Expenses or Project Operating
Expenses, as applicable, as provided in subparagraph (b) above. If the
effective date of the increase is prior in time to the date of the
Adjustment Notice, the First Adjustment Payment shall be increased to
include the amount of the monthly payments, if any, which would have been
made had the Adjustment Notice been received prior to the effective date of
the increase.

    (d) The term "Operating Expenses" as used herein shall include all costs

entire calendar year, and shall include the following costs by way of 
illustration but not limitation: real and personal property taxes and vehicle 
taxes and fees; general and special assessments; costs and expenses incurred 
in contesting the amount of validity of any property tax by appropriate 
proceedings; water and sewer charges; insurance premiums, including the cost 
of rental insurance; the amount of any deductible payable by Landlord as set 
forth in the policy with respect to damage or destruction to all or any 
portion of the Project; license, permit and inspection fees; heat; light; 
power; intrabuilding network cable including service contract fees; 
janitorial and courtesy officer services (if any); fire protection; labor;

cost of any capital improvements made to the Project by Landlord which are 
reasonably calculated to reduce Operating Expenses and/or are required under 
any governmental law or regulation not applicable to the Project or not in 
effect at the time it was constructed, such cost to be amortized over such 
reasonable period as Landlord shall determine and to include a return on 
capital at the rate of ten percent (10%) per annum on the unamortized balance 
or at such higher rate as may have been paid by Landlord on funds borrowed 
for the purpose of constructing such capital improvements; the cost of 
providing a management office at the Project; the cost of providing a manager 
and support staff to operate such office and the Project. The term "property 
taxes" as used herein shall include (i) all real estate taxes and personal 
property taxes and other taxes, charges and assessments, unforeseen as well 
as foreseen, which are levied with respect to the Project, and any 
improvements, fixtures and equipment and other property of Landlord, real or 
personal, located in the Project and used in connection with the operation of 
the Project and the land upon which situated, (ii) any tax, surcharge or 
assessment which shall be levied in addition to or in lieu of real estate or 
personal property taxes, other than taxes covered by Paragraph 12, and (iii) 
any service or other fees collected by governmental agencies in addition to

transaction privilege, or other tax or levy, however denominated, imposed 
upon or measured by the rental reserved hereunder or on Landlord's business 
of leasing the Premises, excepting only net income taxes.

     "Building Operating Expenses" shall include all Operating Expenses 
directly and separately identifiable to the operation and maintenance of the 
Building. "Project Operating Expenses" shall include all Operating Expenses 
incurred in the operation and maintenance of the Project which are not (A) 
Building Operating Expenses or (B) Operating Expenses directly and separately 
identifiable to the operation and maintenance of other buildings in the 
Project.

     (e) Notwithstanding anything to the contrary contained in subparagraph (d)
immediately above, as to each specific category of expense which one or
more tenants of the Building or the Project either pays directly to third
parties or actually reimburses to Landlord (for example, separately metered
utilities, property taxes directly reimbursed to Landlord, etc.) then each
such expense which is actually paid or reimbursed shall not be included in
"Operating Expenses" for purposes of this Paragraph 3. Tenant's Building
and Project Operating Expense Percentages, as appropriate, for each such
category of expense shall be adjusted by excluding from the denominator
thereof the Rentable Area of all such tenants paying such category of
expense directly to third parties or actually reimbursing same directly to
Landlord. Moreover, if Tenant directly pays a third party or actually
reimburses Landlord for any such category of expense, each such category of
expenses which is paid or actually reimbursed by Tenant shall be excluded
from the determination of "Building Operating Expenses" or "Project
Operating Expenses," as applicable, for Tenant to the extent such expense
(after deduction of that portion paid or directly reimbursed by Tenant) was
incurred with respect to space in the Building or Project, respectively,
actually leased to other tenants.

     (f) The annual determination of Building Operating Expenses and Project 
Operating Expenses shall be made by Landlord and the fact that such Operating 
Expenses have in fact been incurred by Landlord shall be certified by a 
nationally recognized firm of certified public accountants designated by 
Landlord. A copy of Landlord's determination and such certification shall be 
made available to Tenant upon request. Landlord's determination and such 
certification shall be final and binding upon Landlord and Tenant.

     (g) The Basic Annual Rent, as adjusted pursuant to Paragraph 2, the 
Additional Rent and all other amounts required to be paid by Tenant 
hereunder, are sometimes herein collectively referred to as, and shall 
constitute, "rent" within the meaning of California Civil Code Section 
1951(a).

Tenant shall not be entitled to interest thereon. Each time, if any, Basic
Annual Rent increases pursuant to the provisions of

this Lease, within five (5) business days thereafter, Tenant shall pay to 
Landlord as an additional security deposit an amount equal to one twelfth 
(1/12) of the difference between the new Basic Annual Rent and the Basic 
Annual Rent in effect immediately prior to such increase. If Tenant defaults 
with respect to any provision of this Lease, including but not limited to the 
provisions relating to the payment of rent, Landlord may, but shall not be 
required to, use, apply or retain all or any part of this security deposit 
for the payment of any rent of any other sum in default, or for the payment 
of any other amount which Landlord may spend or become obligated to spend by 
reason of Tenant's default or to compensate Landlord for any other loss or 
damage which Landlord may suffer by reason of Tenant's default, including 
without limitation, costs and attorneys' fees incurred by Landlord to recover 
possession of the Premises upon a default by Tenant hereunder. If any portion 
of said deposit is so used or applied, Tenant shall, within five (5) days 
after receipt of written demand therefor, deposit cash with Landlord in an 
amount sufficient to restore the security deposit to its original amount and 
Tenant's failure to do so shall constitute a default hereunder by Tenant. If 
Tenant shall fully and faithfully perform every provision of this Lease to be 
performed by it, the security deposit shall be applied against any amounts 
owed by Tenant to Landlord at the expiration or termination of this Lease and 
any balance thereof shall be returned to Tenant (or, at Landlord's option, to 
the last assignee of Tenant's interest hereunder) within the time specified 
in Civil Code Section 1950.7.

5.   REPAIRS

     (a) Subject to Paragraph 5(b), Landlord shall make all necessary repairs 
to the exterior walls, exterior doors, windows, corridors and other common 
areas of the Building and the Project and Landlord shall keep the Building 
and the Project in a safe, clean and neat condition, and use reasonable 
efforts to keep all equipment used in common with other tenants, such as 
elevators, plumbing, heating, air conditioning, intrabuilding network cabling

Paragraphs 14 and 15 hereof, there shall be no abatement of rent and no 
liability of Landlord by reason of any injury to or interference with or 
interruption of Tenant's business arising from the failure of any such 
equipment, the making of any repairs, alterations or improvements in or to 
any portion of the Building or Project or in or to fixtures, appurtenances 
and equipment therein. Tenant waives the right to make repairs at Landlord's 
expense under Section 1942 of the California Civil Code, or under any law, 
statute or ordinance now or hereafter in effect. Landlord shall have no 
obligation to repair until a reasonable time after receipt of notice or 
knowledge of the need for repair. The cost of all such work by Landlord shall 
be included in Operating Expenses pursuant to Paragraph 3.

    (b) Tenant agrees that it will make all repairs to the Premises and 
fixtures therein not required above to be made by Landlord and shall do all 
decorating, remodeling, alteration and painting required by Tenant during the 
term of this Lease. Tenant will pay for any repairs to the Premises, the 
Building or the Project made necessary by any negligence or carelessness of 
Tenant or its assignees, subtenants, employees of their respective agents or 
other persons permitted in the Building or on the Project by Tenant, or any 
of them, and will maintain the Premises, and will leave the Premises upon 
termination of this Lease in a safe, clean, neat and sanitary condition.

     (c) Tenant's repair and maintenance obligations pursuant to Paragraph 
5(b) shall extend to any non-Building standard equipment which is either (a) 
in place in or to serve solely the Premises upon execution of this Lease or 
(b) is installed by or for Tenant (whether by Landlord or Tenant) to serve 
solely the Premises. Such non-standard equipment includes, but is not limited 
to, any supplemental heating, ventilating and air conditioning equipment 
(whether or not located in the Premises), water heaters, dish washers and 
refrigerators. Moreover, Tenant's insurance and indemnification obligations 
pursuant to Paragraph 20 shall extend to all such non-standard equipment and 
to the use and malfunctioning of such equipment. If Landlord undertakes any 
repair or maintenance obligation of Tenant pursuant to Paragraph 5(b) (such 
as equipment located outside of but serving only the Premises), the cost of 
such repair or maintenance shall be reimbursed by Tenant to Landlord, as 
Additional Rent, within ten (10) days after Tenant's receipt of Landlord's 
invoice therefor.

6.   IMPROVEMENTS AND ALTERATIONS

     (a) Landlord shall have no construction obligation pursuant to this Lease
and Tenant shall take the Premises in its current "as-is" condition
without warranty or representation.

     (b) Landlord shall have the right, at any time, and without any liability
to Tenant, to change the arrangement and/or location of entrances or
passageways, doors and doorways, and corridors, elevators, stairs, toilets,

Tenant reasonable notice thereof, to change the name, number or
designation by which the Building or the Project is commonly known.

     (c) After the initial tenant improvements have been completed, Tenant 
shall not make any alterations, additions or improvements without the prior 
written consent of Landlord. All such alterations, additions and improvements

Landlord. All such alterations, additions and improvements (except movable 
furniture, furnishings and trade fixtures) shall become the property of 
Landlord and shall be surrendered with the Premises, as a part thereof, at 
the expiration or earlier termination of the term hereof. All such 
alterations, additions or improvements shall, however, be made by Tenant at 
Tenant's sole expense. Upon termination of the Lease, or, at Landlord's 
option, within thirty (30) days prior to the expiration of the Lease term, 
Tenant shall, upon demand by Landlord, at Tenant's sole cost and expense, 
forthwith remove any alterations, additions or improvements (except those 
made initially at the commencement of Tenant's possession of the Premises) 
made by Tenant and designated by Landlord to be removed, and repair and 
restore the Premises to their original condition, reasonable wear and tear 
excepted. If, at the termination of this Lease, Landlord is unable to 
reasonably provide the amount of space required for Tenant's ongoing 
operation, then Tenant may remove from the Premises the Liebert UPS System 
and the Airflow air conditioning unit which are currently located in the 
Premises for Tenant's use at its new location. Any personal property left on 
or in the Premises at the expiration or earlier termination of this Lease 
shall be disposed of by Landlord in the manner provided by law, including, 
without limitation, California Civil Code Section 1980 ET SEQ. Tenant 
releases Landlord of and from any and all claims and liability for damage to 
or destruction or loss of property left by Tenant upon the Premises at the 
expiration or other termination of this Lease and Tenant hereby indemnifies 
Landlord against any and all claims and liability with respect thereto. Tenant 
further waives all claims to all property (and the proceeds thereof) 
abandoned by Tenant and retained or disposed of by Landlord.

    (d) Tenant shall not commence work on any alteration, addition or 
improvement until and unless Landlord has received at least ten (10) days 
notice that such work is to commence. Tenant shall immediately reimburse 
Landlord for any expense incurred by Landlord in reviewing and approving the 
plans and specifications for such work or by reason of any faulty work done 
by Tenant or Tenant's contractors, or by reason of delays caused by such 
work, or by reason of inadequate cleanup, or which is otherwise incurred by 
Landlord to review the plans and specifications, and monitor and inspect the 
progress of such work. Tenant or its contractors will in no event be allowed 
to make any improvements to the Premises which could possibly affect any of 
the Building systems or to make any structural modification to the Building 
without first obtaining Landlord's consent, which Landlord can withhold in 
its sole and absolute discretion. All work by Tenant shall be scheduled 
through Landlord and shall be diligently and continuously pursued from the 
date of its commencement through its completion. In addition to the 
foregoing, and at Landlord's option, Tenant shall obtain a completion and/or 
performance bond in a form and by a surety acceptable to Landlord and in an 
amount not less than one and one-half (1 1/2) times the estimated cost of 
such alterations, additions or improvements.

     (e) All alterations, additions and improvements to the Premises made by 
Tenant shall comply with the plans therefor approved in advance by Landlord; 
provided, however, Landlord's approval or consent to any such work shall not 
impose any liability upon Landlord nor shall such approval infer that 
Landlord has expressed any opinion or made any warranty regarding the 
adequacy, sufficiency or legality of any such improvements. Such plans and 
any specifications associated therewith shall be prepared by an architect or 
interior designer approved in advance by Landlord. No such work shall proceed 
without Landlord's prior approval of (i) Tenant's contractor(s); (ii) 
certificates of insurance from a company or companies approved by Landlord, 
furnished to Landlord by Tenant's contractor, for combined single limit 
bodily injury and property damage insurance covering comprehensive general 
liability and automobile liability, in an amount not less than One Million 
Dollars ($1,000,000) per occurrence and endorsed to show Landlord as an 
additional named insured, and for workers' compensation as required by law 
(provided, however, nothing in this subparagraph shall release Tenant of its 
other insurance obligations hereunder); and (iii) detailed plans and 
specifications for such work. All such work by Tenant shall be done in a 
first-class workmanlike manner and in conformity with all applicable 
governmental requirements, with valid building permit(s) and/or all other 
permits or licenses when and where required, copies of which shall be 
furnished to Landlord before the work is commenced, and any work not 
acceptable to any governmental authority or agency having or exercising 
jurisdiction over such work, or not reasonably satisfactory to Landlord, 
shall be promptly replaced and corrected at Tenant's expense. All such work 
shall comply with all rules and regulations established by Landlord to ensure 
the safety, cleanliness and good order of the Building and the Project and 
its occupants, including but not limited to those relating to usage of 
elevators and loading docks, establishment of off-Premises staging areas, 
disposal of refuse and the hours of performing operations which result in the 
creation of noise, dust and odors. No such alterations, additions or 
improvements by Tenant shall incorporate therein any hazardous materials, as 
defined in Paragraph 9.

    (f) No antenna, satellite dish, microwave receiver or other receiving or
transmission equipment shall be installed by Tenant in or on the roof of
the Building or elsewhere in the Project except with the prior written
consent of Landlord which consent may be given or withheld by Landlord in
its sole and absolute discretion. Any such installation which may be
approved, shall be subject to such terms and conditions as are provided by
Landlord to Tenant at the time Landlord approves such installation.

7.   LIENS

     Tenant shall keep the Premises and the Building and Project free from 
any liens arising out of any work performed, materials furnished, or 
obligations incurred by or for Tenant. In the event that Tenant shall not, 
within thirty (30) days following the imposition of any such lien, cause the 
same to be released of record by payment or posting of a proper lien release 
bond, Landlord shall have, in addition to all other remedies provided herein 
and by law, the right, but not the obligation, to cause the same to be 
released by such means as it shall deem proper, including payment of or 
defense against the claim giving rise to such lien. All sums paid by Landlord 
and all expenses incurred by it in connection therewith shall create 
automatically an obligation of Tenant to pay an equivalent amount as 
additional rent, which additional rent shall be payable by Tenant within five 
(5) days after Tenant's receipt of Landlord's demand therefor with interest 
at the rate per annum determined pursuant to Paragraph 37 from date of 
payment by Landlord until paid by Tenant. Tenant agrees to indemnify and hold 
Landlord harmless from and against any and all claims for mechanics', 
materialmen's or other liens in connection with any alterations, repairs or 
any work performed, materials furnished or obligations incurred by or for 
Tenant. Nothing herein shall imply any consent by Landlord to subject 
Landlord's estate to liability under any mechanics' or other lien law. Tenant 
shall give Landlord adequate opportunity and Landlord shall have the right to 
post in or on the Premises such notices of nonresponsibility as are provided 
for in the mechanics lien laws of the state of California.

8.   USE OF PREMISES

     Tenant and any of its permitted assignees, sublessees or other occupants 
(collectively "Tenant Parties") shall use the Premises only for the 
purpose(s) set forth in Item 11 of the Basic Lease Provisions and shall not 
use or permit the Premises to be used for any other purpose without the prior 
written consent of Landlord. Without limiting the foregoing, Tenant and the 
Tenant Parties shall not use the Premises, nor permit the Premises to be 
used, for retail purposes nor shall Tenant or the Tenant Parties permit the 
Premises to be used by a governmental or quasi-governmental entity or 
agency (it being understood, however, that Landlord may lease to such an 
entity or agency if Landlord recaptures all or any portion of the Premises 
pursuant to Paragraph 16 below). Tenant shall not use or occupy the Premises 
in violation of law or of the certificate of occupancy issued for the 
Building, and shall, upon five (5) days' written notice from Landlord, 
discontinue any use of the Premises which is declared by any governmental 
authority having jurisdiction to be a violation of law or of such certificate 
of occupancy. Tenant shall comply promptly with any direction of any 
governmental authority having jurisdiction which shall, by reason of the 
nature of Tenant's use or occupancy of the Premises, impose any duty upon 
Tenant or Landlord with respect to the Premises or with respect to the use or 
occupancy thereof. Tenant shall not do or permit to be done anything which 
will invalidate or increase the cost of any fire, extended coverage or any 
other insurance policy covering the Building, the Project and/or property 
located therein and shall comply with all rules, orders, regulations and 
requirements of the Pacific Fire Rating Bureau or any other organization 
performing a similar function. Notwithstanding Paragraph 3, Tenant shall 
promptly upon demand reimburse Landlord, as additional rent, for the full 
amount of any additional premium charged for such policy by reason of 
Tenant's failure to comply with the provisions of this Paragraph, together 
with interest thereon from date of payment by Landlord to date of 
reimbursement by Tenant at the rate per annum determined pursuant to 
Paragraph 37. Such demand for reimbursement shall not be Landlord's exclusive 
remedy. Tenant shall not do or permit anything to be done in or about the 
Premises which will in any way obstruct or interfere with the rights of other 
tenants or occupants of the Building or the Project, or injure or annoy them, 
or use or allow the Premises to be used for any improper, immoral, unlawful 
or objectionable purpose, nor shall Tenant cause, maintain or permit any 
nuisance in, or about the Premises. Tenant shall not commit or suffer to be 
committed any waste in or upon the Premises. Landlord shall not be liable to 
Tenant for any other occupant's or tenant's failure to conduct itself in 
accordance with the provisions of this Paragraph 8, and Tenant shall not be 
released or excused from the performance of any of its obligations under the 
Lease in the event of any such failure.

     Without limiting any of its other obligations pursuant to this Paragraph 
8 or Paragraph 9, Tenant covenants and agrees to comply with all laws, rules, 
regulations and guidelines now or hereafter applicable to the Premises with 
respect to the disposal of water, trash, garbage and other matter (liquid or 
solid) generated by Tenant, the disposal of which is not otherwise the 
express obligation of Landlord under this Lease, including, but not limited 
to, laws, rules, regulations and guidelines with respect to recycling and 
other forms of reclamation (all of which are herein collectively referred to 
as "Waste Management Requirements"). Tenant shall comply with all rules and 
regulations established by Landlord from time to time to comply with Waste 
Management Requirements applicable to Landlord (i) as owner of the Premises 
and (ii) in performing Landlord's obligations under this Lease, if any. 
Tenant's obligations under this Paragraph 8 shall survive the expiration or 
termination of this Lease.

   Tenant shall indemnify, defend, protect and hold Landlord harmless from 
and against all liability (including costs, expenses and attorneys' fees) 
that Landlord may sustain by reason of Tenant's breach of its obligations 
under this Paragraph 8.

alteration of the Premises (all at Tenant's sole cost) to minimize the 
likelihood of a violation of Hazardous Materials Laws as a result of Tenant's 
Use of the Hazardous Materials and/or installation and operation of 
Equipment, and/or (iii) increasing the amount of the security deposit. 
Neither Landlord's consent nor Tenant's obtaining any Permits shall relieve 
Tenant of any of its obligations pursuant to this Paragraph 9. Landlord's 
granting of consent to one request to Use Hazardous Materials and/or install 
and operate Equipment shall not be deemed Landlord's consent to any other 
such request. If Landlord grants its consent to Tenant's request, no 
subtenant, assignee or successor of Tenant shall have the right to Use those 
Hazardous Materials or install or operate that Equipment without again 
complying with the provisions of this Paragraph 9(b)(ii).

          (iii) Notwithstanding the provisions of Paragraphs 9(b)(i) and 
9(b)(ii), Tenant may Use any Substance typically found or used in

expiration or earlier termination of this Lease; and (E) Tenant and its 
Agents comply with all applicable Hazardous Materials Laws.

          (iv) Tenant shall not use or install in or about the Premises any 
asbestos or asbestos-containing materials.

     (c) Tenant shall deliver to Landlord, within thirty (30) days after 
Tenant's receipt of Landlord's written request, a written list identifying 
any Hazardous Materials that Tenant or its Agents then Uses or has Used 
within the last twelve (12) month period in the Project. Each such list shall 
state: (i) the use or purpose of each such Hazardous Material; (ii) the 
approximate quantity of each such Hazardous Material Used by Tenant; (iii) 
such other information as Landlord may reasonably require; and (iv) Tenant's 
written certification that neither Tenant nor its Agents have released, 
discharged or disposed of any Hazardous Materials in or about the Project, or 
transported any Hazardous Materials to or from the Project, in violation of 
any applicable Hazardous Materials Laws. Landlord shall not request Tenant to 
deliver a Hazardous Materials list more often than once during each twelve 
(12) month period, unless Landlord reasonably believes that Tenant or its 
Agents have violated the provisions of this Paragraph 9 (in which case (A) 
Landlord may request such lists as often as Landlord determines is necessary 
until such violation is cured, and (B) Tenant shall provide such lists within 
ten (10) days of each of Landlord's requests, or if an emergency exists, such 
lists shall be immediately provided).

     (d) Tenant shall furnish to Landlord copies of all notices, claims, 
reports, complaints, warnings, asserted violations, documents or other 
communications received or delivered by Tenant, as soon as possible and in 
any event within five (5) days of such receipt or delivery, with respect to 
any actual or alleged Use, disposal or transportation of Hazardous Materials 
in or about the Premises, the Building or the Project. Whether or not Tenant 
receives any such notice, claim, report, complaint, warning, asserted 
violation, document or communication, Tenant shall immediately notify 
Landlord, orally and in writing, if Tenant or any of its Agents knows or has 
reasonable cause to believe that any Hazardous Materials, or a condition 
involving or resulting from the same, is present, in Use, has been disposed 
of, or transported to or from the Premises, the Building or the Project other 
than is previously consented to by Landlord in strict accordance with 
Paragraph 9(b).

     (e) Tenant acknowledges that it, and not Landlord, is in possession and 
control of the Premises for purposes of all reporting requirements under any 
Hazardous Materials Laws. If Tenant or its Agents violate any provision of 
this Paragraph 9, then Tenant shall immediately notify Landlord in writing 
and shall be obligated, at Tenant's sole cost, to abate, remediate, clean-up 
and/or remove from the Project, and dispose of, all in compliance with all 
applicable Hazardous Materials Laws, all Hazardous Materials Used by Tenant 
or its Agents. Such work shall include, but not be limited to, all testing 
and investigation required by Landlord, Landlord's lender and/or ground 
lessor, if any, and any governmental authorities having jurisdiction, and 
preparation and implementation of any remedial action plan required by any 
governmental authorities having jurisdiction. All such work shall, in each 
instance, be conducted to the satisfaction of Landlord and all governmental 
authorities having jurisdiction. If at any time Landlord determines that 
Tenant is not complying with the provisions of this Paragraph 9(e), then 
Landlord may, without prejudicing, limiting, releasing or waiving Landlord's 
rights under this Paragraph 9, separately undertake such work, and Tenant 
shall reimburse all costs incurred by Landlord upon demand.

     (f) Landlord's right of entry pursuant to Paragraph 17 shall include the 
right to enter and inspect the Premises, and the right to inspect Tenant's 
books and records, to verify Tenant's compliance with, or violations of, the 
provisions of this Paragraph 9. Furthermore, Landlord may conduct such 
investigations and tests as Landlord or Landlord's lender or ground lessor 
may require. If Landlord determines that Tenant has violated the provisions 
of this Paragraph 9, or if any applicable governmental agency requires any 
such inspection, investigation or testing, then Tenant, in addition to its 
other obligations set forth in this Paragraph 9, shall immediately reimburse 
Landlord for all costs incurred therewith.

     (g) (i) Tenant shall indemnify, protect, defend (with legal counsel 
acceptable to Landlord in its subjective, good faith judgment) and hold 
harmless Landlord, its partners and its and their respective successors, 
assigns, partners, directors, officers, shareholders, employees, agents, 
lenders, ground lessors and attorneys, and the Project, from and against any 
and all Claims incurred by such indemnified persons, or any of them, in 
connection with, or as the result of: (A) the presence, Use or disposal of 
any Hazardous Materials into or about the Project, or the transportation of 
any Hazardous Materials to or from the Project, by Tenant or its Agents; (B) 
any injury to or death of persons or damage to or destruction of property 
resulting from the presence, Use or disposal of any Hazardous Materials into 
or about the Project, or the transportation of any Hazardous Materials to or 
from the Project, by Tenant or its Agents; (C) any violation of any Hazardous 
Materials Laws; and (D) any failure of Tenant or its Agents to observe the 
provisions of this Paragraph 9. Payment shall not be a condition precedent to 
enforcement of the foregoing indemnification provision. Tenant's obligations 
hereunder shall include, without limitation, and whether foreseeable or 
unforeseeable, all costs of any required or necessary testing, investigation, 
studies, reports, repair, clean-up, detoxification or decontamination of the 
Project, and the preparation and implementation of any closure, removal, 
remedial action or other required plans in connection therewith, and shall 
survive the expiration or earlier termination of the term of this Lease. For 
purposes of these indemnity provisions, any acts or omissions of Tenant, its 
assignees, sublessees, Agents or others acting for or on behalf of Tenant 
(regardless of whether they are negligent, intentional, willful, or unlawful) 
shall be strictly attributable to Tenant.

          (ii) If at any time after the initiation of any suit, action, 
investigation or other proceeding which could create a right of 
indemnification under Paragraph 9(g)(i) Landlord determines that Tenant is 
not complying with the provisions of Paragraph 9(g)(i), then Landlord may, 
without prejudicing, limiting, releasing or waiving the right of 
indemnification provided herein, separately defend or retain separate counsel 
to represent and control the defense as to Landlord's interest in such suit, 
action, investigation or other proceeding. Tenant shall pay all costs of 
Landlord's separate defense or counsel upon demand.

     (h) Upon any violation of the provisions of this Paragraph 9, Landlord 
shall be entitled to exercise any or all remedies available to a landlord 
against a defaulting tenant including, but not limited to, those set forth in 
Paragraph 26.

     (i) By its signature to this Lease, Tenant confirms that: (i) Landlord 
has not made any representation or warranty regarding the environmental 
condition of the Premises, the Building or the Project; and (ii) Tenant has 
conducted its own examination of the Premises, the Building and the Project 
with respect to Hazardous Materials and accepts the same "AS IS" and with no 
Hazardous Materials present thereon.

     (j) No termination, cancellation or release agreement entered into by 
Landlord and Tenant shall release Tenant from its obligations under this 
Paragraph 9 unless specifically agreed to by Landlord in writing at the time 
of such agreement.

     (k) Tenant's covenants and obligations under this Paragraph 9 shall also 
apply to any assignee or sublessee of Tenant, and to any such assignee's or 
sublessee's partners, officers, directors, shareholders, employees, agents, 
contractors and any other third parties entering upon the Project at the 
request or invitation of such assignee or sublessee.

10.  UTILITIES AND SERVICES

     (a) Provided that Tenant is not in default hereunder, Landlord agrees to 
furnish or cause to be furnished to the Premises, the utilities and services 
described, subject to the conditions and in accordance with the standards set 
forth below:

          (i) Landlord shall provide automatic elevator facilities to the 
     Building Monday through Friday, excepting therefrom all holidays 
     recognized by Landlord, hereinafter collectively referred to as 
     "generally accepted business days," from 8:00 a.m. to 6:00 p.m., 
     and on Saturdays from 8:00 a.m. to 12:00 noon, and have at least 
     one elevator available for use at all other times.

          (ii) On generally accepted business days from 8:00 a.m. 
     to 6:00 p.m. and on Saturdays from 8:00 a.m. to 12:00 noon (and at 
     other times for a reasonable additional charge to be fixed by 
     Landlord), Landlord shall ventilate the Premises and furnish air 
     conditioning when in the judgment of Landlord it is required for 
     the comfortable occupancy of the Premises during such days and 
     hours, subject to any requirements or standards relating to, among 
     other things, energy conservation, imposed or established by 
     governmental agencies or cooperative organizations. Landlord shall 
     make available at Tenant's expense after-hours power, including 
     light, and air conditioning to each floor of the Building which 
     shall be controlled by a digital control or other central control 
     system selected by Landlord. Minimum use of after-hours power and 
     air conditioning, the costs thereof and the prior notice required 
     for such services shall be determined from time to time by Landlord 
     and confirmed in writing to Tenant, as the same may change from 
     time to time.

                                                          LANDLORD'S   TENANT'S

          (iii) Landlord shall furnish to the Premises at all times, 
     subject to interruptions beyond Landlord's control, electric 
     current as required by the building standard office lighting 
     (approximately two (2) watts per square foot at 277 volts) and 
     receptacles (approximately one (1) watt per square foot at 110 
     volts). At all times Tenant's use of electric current shall never 
     exceed the capacity of the feeders to the Building or the risers or 
     wiring installation.

          (iv) Landlord shall furnish water for drinking, cleaning and 
     lavatory purposes only.

          (v) Landlord shall provide janitorial services to the Premises 
     comparable to those provided in other first-class office buildings 
     in the vicinity of the Building, provided the same are used 
     exclusively as offices and are kept reasonably in order by Tenant. 
     Landlord shall not be responsible or liable for any act or omission 
     or commission on the part of the persons employed to perform said 
     janitorial services, which shall be performed at Landlord's 
     direction without interference by Tenant or Tenant's employees, 
     agents, contractors, licensees, directors, officers, partners, 
     trustees, visitors or invitees (collectively, "Tenant Parties"). If 
     the Premises are not used exclusively as offices, Tenant or persons 
     approved by Landlord shall keep the Premises clean and in order to 
     the satisfaction of Landlord, but at Tenant's sole expense. No 
     persons other than Tenant and those persons approved by Landlord 
     shall be permitted to enter the Building for the purpose of keeping 
     the Premises clean and in order. Tenant shall pay to Landlord the 
     cost of removal of any of Tenant's refuse and rubbish, to the 
     extent that the same exceeds the refuse and rubbish usually 
     attendant upon the use of the Premises as offices.

          (vi) Landlord shall replace, as necessary, the fluorescent 
     tubes in the building standard lighting fixtures installed by 
     Landlord. Tenant shall replace, as necessary, all bulbs and 
     fluorescent tubes in non building standard lighting fixtures, if 
     any, installed in the Premises. If Tenant shall fail to make any 
     such replacement within five (5) days after written notice from 
     Landlord, Landlord may make such replacement and charge the cost of 
     labor and materials involved therein to Tenant, as additional rent.

          (vii) Landlord shall provide at all times, subject to 
     interruption due to equipment failures, maintenance and/or repairs, 
     intrabuilding network cabling to permit connection of telephone 
     services from the Minimum Point of Entry as designated by Pacific 
     Bell to the telephone closet located on the floor of the Building 
     on which the Premises is located.

     (b) Landlord may impose a reasonable charge for any utilities and 
services, including without limitation, air conditioning, electric 
current and water, required to be provided by Landlord by reason of any 
use of the Premises at any time other than the hours from 8:00 a.m. to 
6:00 p.m. on generally accepted business days or the hours from 8:00 
a.m. to 12:00 noon on Saturdays or any use beyond what Landlord agrees 
to furnish as described above, or special electrical, cooling and 
ventilating needs created in certain areas by hybrid telephone 
equipment, computers and other similar equipment or uses. At Landlord's 
option, separate meters for such utilities and services may be installed 
for the Premises and Tenant, upon demand therefor, shall immediately pay 
Landlord for the installation, maintenance and repair of such meters.

     (c) Tenant agrees to cooperate fully at all times with Landlord and 
to abide by all regulations and requirements which Landlord may 
prescribe for the use of the above utilities and services. Any failure 
to pay any excess costs as described above shall constitute a breach of 
the obligation to pay rent under this Lease and shall entitle Landlord 
to the rights herein granted for such breach.

     (d) Landlord reserves the right in its sole and absolute discretion 
to reduce, interrupt or cease service of the heating, air conditioning, 
ventilation, elevator, plumbing, electrical systems, telephone systems 
(to the extent provided by Landlord) and/or utilities services of the 
Premises, the Building or the Project, for (i) the making of any 
repairs, additions, alterations or improvements to the Premises, 
Building or Project until said repairs, additions, alterations or 
improvements shall have been completed or (ii) any accident, breakage, 
strikes, lockouts or other labor disturbance or labor dispute of any 
character, governmental regulation, moratorium or other governmental 
action, inability by exercise of reasonable diligence to obtain 
electricity, water or fuel, or by any other cause beyond Landlord's 
reasonable control. In such event, Landlord shall not be liable for, and 
Tenant shall not be entitled to, any abatement or reduction of rent by 
reason of Landlord's failure to furnish any of the foregoing. Landlord 
shall not be in breach of this Lease and shall not be liable in damages 
(including but not limited to any damages, compensation or claims 
arising from any interruption or cessation of Tenant's business) or 
otherwise for failure, stoppage or interruption of any such service, nor 
shall the same be construed either as an eviction of Tenant, or work an 
abatement of rent, or relieve Tenant from the operation of any covenant 
or agreement. In the event of any failure, stoppage or interruption 
thereof, however, Landlord shall use reasonable diligence to resume 
service promptly where it is within Landlord's reasonable control to do 
so.

     (e) Landlord, in its sole and absolute discretion, may elect to 
contract for the services of individuals that will monitor the systems 
and operations of the Building and Project. In this connection, Landlord 
may also elect to station some of these individuals in the lobby of the 
Building. Such individuals are not security personnel and will not 
provide protective services to any of the tenants of the Building, 
including Tenant.

     (f) Notwithstanding anything hereinabove to the contrary, Landlord 
reserves the right from time to time to make reasonable and nondiscriminatory 
modifications to the above standards for utilities and services.

     (g) Tenant shall pay for all telephone service to the Premises and shall 
contract directly with the providing company for such service, and Landlord 
shall have no responsibilities thereto.

11.  RULES AND REGULATIONS

     Tenant agrees to abide by all rules and regulations of the Building and 
the Project imposed by Landlord as set forth in Exhibit "C" attached hereto, 
as the same may be changed from time to time upon reasonable notice to 
Tenant. Any such change shall be effective upon delivery of a copy thereof to 
Tenant. These rules and regulations are imposed for the cleanliness, good 
appearance, proper maintenance, good order and reasonable use of the 
Premises, the Building and the Project, and as may be necessary for the 
enjoyment of the Building and the Project by all tenants and their clients, 
customers and employees. A breach of the rules and regulations shall not be 
grounds for termination of this Lease unless Tenant continues to breach the 
same after ten (10) days' written notice by Landlord; provided, however, that 
any such notice shall be in lieu of, and not in addition to, any notice 
required under Paragraph 26, below, or Section 1161, ET SEQ., of the 
California Code of Civil Procedure, as amended. Landlord shall not be liable 
to Tenant for the failure of any other tenant, its agents or employees, to 
conform to the rules and regulations.

12.  TAXES ON TENANT'S PROPERTY

     (a) Tenant shall be liable for and pay ten (10) days before delinquency, 
all taxes, levies and assessments levied against any personal property or 
trade fixtures placed by Tenant in or about the Premises, and, when possible, 
Tenant shall cause such personal property and trade fixtures to be assessed 
and billed separately from the Building and the Premises. If any such taxes, 
levies and assessments on Tenant's personal property or trade fixtures are 
levied against Landlord or Landlord's property or if the assessed value of 
the Building or the Project is increased by the inclusion therein of a value 
placed upon such personal property or trade fixtures of Tenant and if 
Landlord pays the taxes, levies and assessments based upon such increased 
assessment, which Landlord shall have the right to do regardless of the 
validity thereof, but only under proper protest if requested by Tenant, 
Tenant shall upon demand repay to Landlord, as additional rent, the taxes, 
levies and assessments so levied against Landlord, or the proportion of such 
taxes, levies and assessments resulting from such increase in the assessment, 
together with interest thereon from the date of payment by Landlord to the 
date of reimbursement by Tenant at the rate determined pursuant to Paragraph 
37. It is provided, however, that in any such event Tenant shall have the 
right, in the name of Landlord and with Landlord's full cooperation but 
without any cost to Landlord, to bring suit in any court of competent 
jurisdiction to recover the amount of any such taxes, levies and assessments 
so paid under protest, any amount so recovered to belong to Tenant.

     (b) If the tenant improvements in the Premises, whether installed and/or 
paid for by Landlord or Tenant and whether or not affixed to the real 
property so as to become a part thereof, are assessed for real property tax 
purposes at a valuation higher than the valuation at which tenant 
improvements conforming to Landlord's "building standard" in other space in 
the Building are assessed, then the real property taxes and assessments 
levied against Landlord or the Building or the Project by reason of such 
excess assessed valuation shall be deemed to be taxes levied against personal 
property of Tenant and shall be governed by the provisions of subparagraph 
(a) above. If the records of the County Assessor are available and 
sufficiently detailed to serve as a basis for determining whether said tenant 
improvements are assessed at a higher valuation than Landlord's "building 
standard," such records shall be binding on both Landlord and Tenant; 
otherwise the actual cost of construction shall be the basis for such 
determination.

13.  INTENTIONALLY OMITTED

14.  FIRE OR CASUALTY

     (a) In the event the Premises, or access to them, are wholly or 
partially destroyed by fire or other casualty covered by the form of fire and 
extended coverage insurance maintained by Landlord, Landlord shall rebuild, 
repair or restore the Premises and access thereto to substantially the same 
condition as when the same were furnished to Tenant, excluding any 
improvements installed by Tenant and any of Tenant's personal property, and 
this Lease shall continue in full force and effect. In the event, however, 
that the Building is so damaged or destroyed to the extent of more than 
one-third (1/3) of its replacement cost, or to any substantial extent by a 
casualty not so covered, Landlord may elect by written notice to Tenant given 
within twenty (20) days after the occurrence of the casualty to terminate 
this Lease in lieu of so restoring the Premises, in which event this Lease 
shall terminate as of the date of the occurrence of the casualty. Landlord 
shall in no event be obligated to make any repairs or replacement of any 
items other than those items installed by or at the


                                                          LANDLORD'S   TENANT'S

expense of Landlord. If the Premises are rendered totally or partially 
untenantable, rent shall abate during the period of reconstruction in the 
same proportion to the total rent as the portion of the Premises rendered 
untenantable bears to the entire Premises. Any such rental abatement shall 
not defeat or diminish Landlord's rights to recover upon any rental 
interruption insurance maintained by Landlord pursuant to Paragraph 20. In no 
event shall Tenant be entitled to any compensation or damages for loss of use 
of the whole or any part of the Premises or for any inconvenience occasioned 
by any such destruction, rebuilding or restoration of the Premises, the 
Building or access thereto. Tenant waives the provisions of California Civil 
Code Sections 1932(2) and 1933(4) and any present and future laws and case 
decisions to the same effect.

     (b) Notwithstanding anything to the contrary contained in Paragraph 
14(a) above, if the Premises or the Building or the Project is wholly or 
partially damaged or destroyed within the final twelve (12) months of the 
Term of this Lease, Landlord may, at its option, by giving Tenant notice 
within sixty (60) days after notice to Landlord of the occurrence of such 
damage or destruction, elect to terminate the Lease. Furthermore, upon 
termination of this Lease pursuant to this Paragraph 14(b), Tenant and 
Landlord hereby agree (except as expressly provided for otherwise in this 
Lease) to release each other from any and all obligations and liabilities 
with respect to the Lease except such obligations and liabilities which arise 
or accrue prior to such termination.

15. EMINENT DOMAIN

     (a) In case the whole of the Premises, or such part thereof as shall 
substantially interfere with Tenant's use and occupancy thereof, shall be 
taken by any lawful power or authority by exercise of the right of eminent 
domain, or sold to prevent such taking or threat of such taking, either 
Tenant or Landlord may terminate this Lease effective as of the date 
possession is required to be surrendered to said authority. Except as 
provided herein, Tenant shall not because of such taking assert any claim 
against Landlord or the taking authority for any compensation because of such 
taking, and Landlord shall be entitled to receive the entire amount of any 
award without deduction for any estate or interest of Tenant. In the event 
the amount of property or the type of estate taken shall not substantially 
interfere with Tenant's use of the Premises, Landlord shall be entitled to 
the entire amount of the award without deduction for any estate or interest 
of Tenant. In such event, Landlord shall promptly proceed to restore the 
Premises to substantially their condition prior to such partial taking, and a 
proportionate allowance shall be made to Tenant for the rent corresponding to 
the time during which, and to the part of the Premises of which, Tenant shall 
be so deprived on account of such taking and restoration. Any such rental 
abatement shall not defeat or diminish Landlord's rights to recover upon any 
rental interruption insurance maintained by Landlord pursuant to Paragraph 
20. Nothing contained in this Paragraph 15(a) shall be deemed to give 
Landlord any interest in, or prevent Tenant from seeking any award against 
the taking authority for, the taking of personal property and fixtures 
belonging to Tenant or for relocation or business interruption expenses 
recoverable from the taking authority. Landlord may, without any obligation 
to Tenant, agree to sell and/or convey to any taking authority the Premises, 
the Building, the Project or any portion thereof sought by such taking 
authority, free from this Lease and the rights of Tenant hereunder, without 
first requiring that any action or proceeding be instituted or pursued to 
judgment.

     (b) In the event of a temporary taking of the Premises or any part of 
the Premises and/or of Tenant's rights to the Premises or under this Lease, 
this Lease shall not terminate, nor shall Tenant have the right to any 
abatement of rent or of any other payments owed to Landlord pursuant to this 
Lease. Any award made to Tenant by reason of such temporary taking shall 
belong entirely to Tenant.

     (c) This Paragraph 15 shall be Tenant's sole and exclusive remedy in the 
event of a taking or condemnation. Tenant hereby waives the benefit of 
California Code of Civil Procedure Section 1265.130. Upon termination of the 
Lease pursuant to this Paragraph 15, Tenant and Landlord hereby agree (except 
as expressly provided for otherwise in this Lease) to release each other from 
any and all obligations and liabilities with respect to the Lease except such 
obligations and liabilities which arise or accrue prior to such termination.

16.  ASSIGNMENT AND SUBLETTING

     (a) Tenant shall not, either voluntarily or involuntarily or by 
operation of law, assign, sublet, mortgage or otherwise encumber all or any 
portion of its interest in this Lease or in the Premises or permit the 
Premises to be occupied by anyone other than Tenant or Tenant's employees 
without obtaining the prior written consent of Landlord, which consent shall 
be subject to the provisions of subsections (b) through (j) below. Any such 
attempted assignment, subletting, mortgage or other encumbrance without such 
consent shall be null and void and of no effect.

     (b) No assignment, subletting, mortgage or other encumbrance of Tenant's 
interest in this Lease shall relieve Tenant of its obligation to pay the rent 
and to perform all of the other obligations to be performed by Tenant 
hereunder. In this connection, any such assignment, sublease or encumbrance 
shall expressly provide that it is subject to the terms and provisions of 
this Lease. Moreover, any subletting by Tenant of any portion of the Premises 
shall be at a market rental rate and upon market terms and, if Landlord so 
requests, shall require that the assignee or sublessee remit directly to 
Landlord, on a monthly basis, all rent due to Tenant by

                                                          LANDLORD'S   TENANT'S

said assignee or sublessee. For this purpose, "market" shall mean a rental 
rate and terms comparable to the rental rate and terms then being offered by 
other landlords leasing comparable space in comparable commercial high-rise 
office buildings that are located within a one (1) mile radius of the 
Building. The acceptance of rent by Landlord from any other person shall not 
be deemed to be a waiver by Landlord of any provision of this Lease or to be 
a consent to any subletting, assignment, mortgage or other encumbrance. 
Consent to one sublease, assignment, mortgage or other encumbrance shall not 
be deemed to constitute consent to any subsequent attempted subletting, 
assignment, mortgage or other encumbrance.

     (c) If Tenant desires at any time to assign this Lease or to sublet the 
Premises or any portion thereof, it shall first notify Landlord of its desire 
to do so and shall submit in writing to Landlord (i) the name of the proposed 
subtenant or assignee; (ii) the nature of the proposed subtenant's or 
assignee's business to be carried on in the Premises, (iii) the terms and 
provisions of the proposed sublease or assignment and the proposed effective 
date thereof; and (iv) such financial information as Landlord may reasonably 
request concerning the proposed subtenant or assignee. The submission 
pursuant to clause (iii) shall include a copy of any agreement, escrow 
instructions or other document which contains or memorializes the terms and 
provisions of the transaction for which Landlord's consent is required. 
Similarly, if Tenant desires to mortgage or encumber its interest in this 
Lease, Tenant shall first supply to Landlord in writing such information as 
to such transaction as may be reasonably requested by Landlord.

     (d) As a condition to Landlord's consent to such assignment or 
subletting, Landlord shall be entitled to receive, in the case of a 
subletting, all rent (however denominated and paid) payable by the subtenant 
to Tenant in excess of that payable by Tenant to Landlord pursuant to the 
other provisions of this Lease and, in the case of an assignment, all 
consideration given, directly or indirectly, by the assignee to Tenant in 
connection with such assignment, less normal and usual costs incurred by 
Tenant in connection with such subletting or assignment amortized over the 
length of the term of such assignment or sublease. For the purposes of this 
subparagraph, the term "rent" shall mean all consideration paid or given, 
directly or indirectly, for the use of the Premises or any portion thereof. 
The term "consideration" shall mean and include money, services, property or 
any other thing of value such as payment of costs, cancellation of 
indebtedness, discounts, rebates and the like. "Normal and usual costs" shall 
only mean the following: broker's commission paid by Tenant to a broker 
independent of Tenant in connection with such assignment or subletting; legal 
fees incurred by Tenant in processing such assignment or subletting; 
out-of-pocket costs incurred by Tenant in advertising for an assignee or 
subtenant; and out-of-pocket costs incurred by Tenant to remodel or renovate 
the area subject to such subletting or assignment (which costs shall not 
exceed the cost of providing "Building Standard Improvements" in the 
quantities specified in Exhibit "B" for such assignee or subtenant). "Sublet" 
and "sublease" shall include a sublease as to which Tenant is sublessor and 
any sub-sublease or other sub-subtenancy, irrespective of the number of 
tenancies and tenancy levels between the ultimate occupant and Landlord, as 
to which Tenant receives any consideration, as defined in this subparagraph, 
and Tenant shall require on any sublease which it executes that Tenant 
receive the profit from all sub-subtenancies, irrespective of the number of 
levels thereof. Any rent or other consideration which is to be passed through 
to Landlord by Tenant pursuant to this subparagraph shall be paid to Landlord 
promptly upon receipt by Tenant and shall be paid in cash, irrespective of 
the form in which received by Tenant from any subtenant or assignee. In the 
event that any rent or other consideration received by Tenant from a 
subtenant or assignee is in a form other than cash, Tenant shall pay to 
Landlord in cash the fair value of such consideration.

     (e) At any time within thirty (30) days after Landlord's receipt of the 
last of the information specified in subparagraph (c) above, Landlord may by 
written notice to Tenant elect (i) to disapprove of such assignment or 
sublease, (ii) to sublease the Premises or the portion thereof so proposed to 
be subleased by Tenant, or to take an assignment of Tenant's leasehold 
estate hereunder, or such part thereof as shall be specified in said notice, 
on the same terms as those stated in this Lease and in turn sublease or 
assign to the proposed subtenant or assignee on the same terms as those 
offered by Tenant to the proposed subtenant or assignee, as the case may be; 
or (iii) to terminate this Lease as to the portion (including all) of the 
Premises so proposed to be subleased or assigned, with a proportionate 
abatement in the rent payable hereunder. It is provided, however, that if the 
proposed sublease will cover less than one half (1/2) of the area of the 
Premises covered by this Lease and will have a term (including all options to 
renew or extend the same) of less than two (2) years and will terminate more 
than two (2) years prior to the expiration date of this Lease, Landlord shall 
not be entitled to exercise option (ii) above, but may exercise option (i). 
Tenant shall, at Tenant's own cost and expense, discharge in full any 
commissions which may be due and owing as the result of any proposed 
assignment or subletting, whether or not the Premises are recaptured pursuant 
hereto and rented by Landlord to the proposed subtenant or assignee or any 
other tenant. If Landlord does not disapprove the proposed subletting or 
assignment in writing and does not exercise any option set forth in this 
subparagraph (e) within said thirty (30) day period, Tenant may within ninety 
(90) days after the expiration of said thirty (30) day period enter into a 
valid assignment or sublease of the Premises or portion thereof, upon the 
terms and conditions set forth in the information furnished by Tenant to 
Landlord pursuant to subparagraph (c) above. It is provided, however, that 
any material change in such terms shall be subject to Landlord's consent and 
rights of


                                                          LANDLORD'S   TENANT'S

termination and recapture as provided in this Paragraph and, provided 
further, that any amount to be paid by Tenant in connection with such 
subletting or assignment pursuant to subparagraph (d) above shall be paid to 
Landlord upon consummation of such transaction.

     (f) Landlord shall have the right to approve or disapprove any proposed 
assignee or subtenant. In exercising such right of approval or disapproval, 
Landlord shall be entitled to take into account any fact or factor which 
Landlord reasonably deems relevant to such decision, including but not 
necessarily limited to the following, all of which are agreed to be 
reasonable factors for Landlord's consideration:

          (i) The financial strength of the proposed assignee or 
     subtenant, including the adequacy of its working capital to pay all 
     expenses anticipated in connection with any proposed remodeling of 
     the Premises.

          (ii) The proposed use of the Premises by such proposed 
     assignee or subtenant and the compatibility of such proposed use 
     within the quality and nature of the other uses in the Building.

          (iii) Any violation which the proposed use by such proposed 
     assignee or subtenant would cause of any other rights granted by 
     Landlord to other tenants of the Building or the Project.

          (iv) Any adverse impact of the proposed use of the Premises by 
     such proposed assignee or subtenant upon the parking or other 
     services provided for Building or Project tenants generally.

          (v) Whether there then exists any default by Tenant pursuant to 
     this Lease or any non-payment or non-performance by Tenant under 
     this Lease which, with the passage of time and/or the giving of 
     notice, would constitute a default under this Lease.

          (vi) The business reputation, character, history and nature of 
     the business of the proposed assignee or subtenant.

          (vii) Whether the proposed assignee or subtenant is a person 
     with whom Landlord has negotiated for space in the Project during 
     the twelve (12) month period ending with the date Landlord receives 
     notice of such proposed assignment or subletting.

          (viii) Whether the proposed assignee or subtenant is a 
     governmental entity or agency.

Moreover, Landlord shall be entitled to be reasonably satisfied that each and 
every covenant, condition or obligation imposed upon Tenant by this Lease and 
each and every right, remedy or benefit afforded Landlord by this Lease is 
not impaired or diminished by such assignment or subletting. Landlord and 
Tenant acknowledge that the express standards and provisions set forth in 
this Lease dealing with assignment and subletting, including those set forth 
in this subparagraph (f) have been freely negotiated and are reasonable at 
the date hereof taking into account Tenant's proposed use of the Premises and 
the nature and quality of the Building and Project. No withholding of consent 
by Landlord for any reason deemed sufficient by Landlord shall give rise to 
any claim by Tenant or any proposed assignee or subtenant or entitle Tenant 
to terminate this Lease, to recover contract damages or to any abatement of 
rent. In this connection, Tenant hereby expressly waives its rights under 
California Civil Code Section 1995.310. Moreover, approval of any assignment 
of Tenant's interest shall, whether or not expressly so stated, be 
conditioned upon such assignee assuming in writing all obligations of Tenant 
hereunder.

     (g) All options to extend, renew or expand, all exterior sign rights and 
all reserved, reduced cost or free parking rights, in each case if any, 
contained in this Lease are personal to Tenant. Consent by Landlord to any 
assignment or subletting shall not include consent to the assignment or 
transfer of any such rights or options with respect to the Premises or any 
other special privileges or extra services granted to Tenant by this Lease, 
any addendum or amendment hereto or any letter agreement. All such options, 
rights, privileges and extra services shall terminate upon such subletting or 
assignment unless Landlord specifically grants the same in writing to such 
assignee or subtenant.

     (h) The voluntary or other surrender of this Lease by Tenant or a mutual 
cancellation hereof shall not work a merger, and shall, at the option of 
Landlord, terminate all or any existing subleases or subtenancies or shall 
operate as an assignment to Landlord of such subleases or subtenancies. 
Tenant agrees to reimburse Landlord for Landlord's reasonable costs and 
attorneys' fees incurred in connection with the processing and documentation 
of any such requested assignment, subletting, transfer, change of ownership 
or hypothecation of this Lease or Tenant's interest in and to the Premises.

     (i) Landlord shall be permitted to hire outside contractors to review 
all assignment and subletting documents and information and Tenant shall 
reimburse Landlord for the cost thereof, including reasonable attorneys' 
fees, on demand.

     (j) The foregoing notwithstanding, Tenant may assign this Lease at any 
time, or sublease all or part of the Premises, without receipt of Landlord's 
consent, to any entity which acquires all or part of Tenant, or which is 
acquired in whole or in part by Tenant, or which is controlled by Tenant, or 
which entity controls, Tenant (any such party hereinafter referred to as an 
"affiliate") so long as such transaction was not entered into as a subterfuge 
to avoid the obligations and restrictions of this Lease. In connection with 
any transaction of the type described in this subparagraph (j):

          (A) Any sublease shall be subject to all of the terms and 
provisions of this Lease and shall be terminable by Landlord upon the 
expiration or any earlier termination of this Lease, including a termination 
by mutual agreement of Landlord and Tenant.

          (B) In connection with any assignment, the assignee shall, within 
ten (10) days after receipt of written request from Landlord, execute and 
deliver to Landlord a written assumption of the obligations of Tenant 
pursuant to this Lease accruing from and after the effective date of the 
assignment and in form and substance reasonably satisfactory to Landlord.

          (C) No such assignment or subletting shall release Tenant from any 
of the obligations of Tenant hereunder, whether accruing prior to or 
subsequent to the effective date of such transaction.

          (D) No such transaction shall be accompanied by a change in use 
from that permitted pursuant to Paragraph 11 of the Basic Lease Provisions.

          (E) Within ten (10) days after the effective date of such 
transaction, Tenant shall notify Landlord in writing of such occurrence, the 
effective date thereof, the name of the assignee or subtenant, any change in 
the addresses for notice pursuant to this Lease and the facts which bring 
such transaction within the scope of this subparagraph (j).

17. ACCESS

     Landlord reserves and shall at any time and all times have the right to 
enter the Premises to inspect the same, to supply janitorial service and any 
other service to be provided by Landlord to Tenant hereunder, to submit said 
Premises to prospective purchasers, tenants or actual or prospective lenders, 
to post notices of non-responsibility, to use and maintain pipes and conduits 
in and through the Premises, and to alter, improve or repair the Premises or 
any other portion of the Building, all without being deemed guilty of an 
eviction of Tenant and without abatement of rent, and may for that purpose 
erect scaffolding and other necessary structures where reasonably required by 
the character of the work to be performed, provided that the business of 
Tenant shall be interfered with as little as is reasonably practicable. 
Landlord may enter by means of a master key without liability to Tenant for 
any damage caused by Landlord entering the Premises, except for damage to 
Tenant's personal property caused by any failure of Landlord to exercise due 
care. Tenant shall not disturb any notices or other items placed by Landlord 
in the Premises. Tenant hereby waives any claim for damages for any injury or 
inconvenience to or interference with Tenant's business, any loss of 
occupancy or quiet enjoyment of the Premises, and any other loss occasioned 
thereby. For each of the aforesaid purposes, Landlord shall at all times have 
and retain a key with which to unlock all of the doors in, upon and about the 
Premises, excluding Tenant's vaults and safes, and Landlord shall have the 
right to use any and all means which Landlord may deem proper to open said 
doors in an emergency in order to obtain entry to the Premises. Any lock 
installed by Tenant shall be of a type and style designated by Landlord 
concurrently with such installation. Any entry to the Premises obtained by 
Landlord by any of said means shall not under any circumstances be construed 
or deemed to be a forcible or unlawful entry into, or a detainer of, the 
Premises, or any eviction of Tenant from the Premises or any portion thereof. 
No provision of this Lease shall be construed as obligating Landlord to 
perform any repairs, alterations or decorations except as otherwise expressly 
agreed to be performed by Landlord.

18.  SUBORDINATION; ATTORNMENT; ESTOPPEL CERTIFICATES; FINANCIAL STATEMENTS

     (a) This Lease and the rights of Tenant hereunder, at Landlord's 
election, shall be junior, subject, and subordinate to the lien of any ground 
or underlying lease, mortgage, deed of trust, and other security instrument 
of any kind now or hereafter covering the Premises, the Building or the 
Project, or any portion of any thereof, and to any and all advances made 
thereunder, interest thereon or costs incurred pursuant thereto (with respect 
to mortgages or deeds of trust) and any amendments, modifications, renewals, 
supplements, consolidations, replacements or extensions thereto. Such 
priority shall be established without the necessity of the execution and 
delivery of any further instruments on the part of Tenant to effect such 
subordination. Landlord or any ground lessor, mortgagee or beneficiary under 
a deed of trust may at any time cause such subordination by giving notice 
thereof to Tenant at least sixty (60) days before the subordination is to 
become effective. Notwithstanding the foregoing, Tenant covenants and agrees 
to (a) execute and deliver upon demand such further instruments evidencing 
such subordination of this Lease or subordination of such mortgage, deed of


                                                          LANDLORD'S   TENANT'S

trust or ground lease as may be requested by Landlord and (b) supply such 
financial information concerning Tenant as may be requested by any ground 
lessor or lender, prospective purchaser or Landlord, in connection with such 
subordination, within ten (10) business days after demand. If Tenant fails to 
execute such further instruments within ten (10) business days after demand, 
Landlord may execute such documents on behalf of Tenant as Tenant's 
attorney-in-fact. Tenant does hereby make, constitute and irrevocably appoint 
Landlord as Tenant's attorney-in-fact and in Tenant's name, place and stead, 
to execute such instruments in accordance with this subparagraph. In 
addition, Tenant's failure to execute such further instruments within ten 
(10) business days after demand shall constitute a material breach of this 
Lease. Notwithstanding subordination by Tenant to any existing or future 
lienholder, Tenant's right to quiet possession of the Premises shall not be 
disturbed so long as Tenant shall pay the rent and observe and perform all of 
the provisions of this Lease to be observed and performed by Tenant, unless 
this Lease is terminated pursuant to specific provisions relating thereto 
contained herein. In the event of the foreclosure of any such lien or 
encumbrance, Tenant shall attorn to the then owner who owns or acquires title 
to the Building or Project and will recognize such owner a Landlord under 
this Lease. Tenant hereby waives any right to terminate this Lease because of 
any such foreclosure.

     (b) Notwithstanding the foregoing, and without the consent of Tenant, 
the holder of any mortgage or deed of trust or the beneficiary thereunder 
shall have the right to elect to be subject and subordinate to this Lease, 
with such subordination to be effective upon such terms and conditions as 
such holder or beneficiary may direct and which are not inconsistent with the 
provisions of this Paragraph 18.

     (c) Tenant shall at any time and from time to time upon not less than 
twenty (20) days prior notice by Landlord, execute, acknowledge and deliver 
to Landlord a statement in writing (i) certifying that this Lease is 
unmodified and in full force and effect (or if there have been modifications, 
that the same is in full force and effect as modified and stating the 
modifications), and the dates to which the Basic Annual Rent, Additional Rent 
and other charges have been paid in advance, if any, (ii) stating whether or 
not to the best knowledge of Tenant, Landlord is in default in the 
performance of any covenant, agreement or condition contained in this Lease 
and, if so, specifying each such default of which Tenant may have knowledge 
and (iii) acknowledging (if true) the accuracy of such other facts as are 
included in such statement by Landlord. Any such statement delivered pursuant 
to this subparagraph may be relied upon by any prospective purchaser of the 
fee of the Building or the Project or any mortgagee, ground lessor or other 
like encumbrancer thereof or any assignee of any such encumbrancer upon the 
Building or the Project. If Tenant fails to deliver such statement within 
such time, such failure shall, at Landlord's option, be deemed to be Tenant's 
irrevocable appointment of Landlord as Tenant's special attorney-in-fact in 
connection with the preparation and execution of any such statement and such 
execution by Landlord as Tenant's attorney-in-fact shall be conclusive upon 
Tenant that (A) this Lease is in full force and effect, without modification 
except as may be represented by Landlord, (B) that there are no uncured 
defaults in Landlord's performance, (C) that with the exception of the amount 
indicated in Item 12 of the Basic Lease Provisions, not more than one month's 
Basic Annual Rent has been paid in advance and (D) that any other statements 
of fact included by Landlord in the statement are correct. Tenant shall be 
liable for all loss, cost or expense resulting from the failure of any ground 
lease, sale or funding of any loan caused by any material misstatement 
contained in any estoppel certificate supplied by Tenant or resulting from 
failure of Tenant to deliver any such statement.

     (d) In addition, and not in lieu of the foregoing, within ten (10) days 
after the Commencement Date, Tenant shall execute and deliver to Landlord a 
certificate substantially in the form of Exhibit "D" attached hereto, 
indicating thereon any exceptions thereto which Tenant claims to exist at 
that time. Failure of Tenant to execute and deliver such certificate within 
such time period shall constitute an acceptance of the Premises and the 
acknowledgment and agreement by Tenant that the statements included in 
Exhibit "D" are true and correct without exception.

19.  SALE BY LANDLORD

     In the event of a sale, transfer or conveyance by Landlord of the 
Building, the same shall operate to release Landlord from any and all 
liability under this Lease. Tenant's right to quiet possession of the 
Premises shall not be disturbed so long as Tenant shall pay the rent and 
observe and perform all of the provisions of this Lease to be observed and 
performed by Tenant, unless this Lease is terminated pursuant to specific 
provisions relating thereto contained herein. If any security deposit has 
been made by Tenant, Landlord may transfer the balance of such security 
deposit (after lawful deductions and in accordance with California Civil Code 
Section 1950.7), after notice to Tenant, to the purchaser, and thereupon 
Landlord shall be discharged from any further liability with respect thereto.

20.  NONLIABILITY AND INDEMNIFICATION OF LANDLORD; INSURANCE

     (a) LANDLORD'S NONLIABILITY. Subject to Paragraphs 20('s) and 21 below, 
Landlord and its partners, and their respective partners, officers, agents 
and employees shall not be liable for Tenant's loss of income or extra 
expense or for any damage to Tenant's property, nor for loss of damage to 
property by theft or otherwise, nor


                                                          LANDLORD'S   TENANT'S

for any injury or damage which may be sustained by the person, goods, wares, 
merchandise or property of Tenant, its employees, invitees or customers or 
any other person in or about the Premises caused by or resulting from any 
peril which may affect the Premises, including without limitation fire, 
explosion, falling plaster, steam, electricity, gas, water or rain, which may 
leak or flow from or into any part of the Premises, or from the breakage, 
leakage, obstruction or other defects of the pipes, sprinklers, wires, 
appliances, plumbing, air conditioning or lighting fixtures of the same, 
whether such damage or injury results from conditions arising upon the 
Premises or upon other portions of the Building, or from other sources. 
Landlord shall not be liable for any damages arising from any act or neglect 
of any other tenant or occupant of the Project or any of their officers, 
employees, agents, representatives, customers and invitees and Tenant hereby 
waives any such right it may have against Landlord. Tenant shall give prompt 
notice to Landlord in case of fire or accidents in the Premises or of defects 
therein or in the fixtures or equipment. Any claim, defense, or other right 
of Tenant arising in connection with this Lease or with negotiations before 
this Lease was signed shall be barred unless Tenant files an action or 
interposes a defense based thereon within one hundred eighty (180) days after 
the date of the alleged event on which Tenant is basing its claim, defense or 
right.

     (b) INDEMNIFICATION. Subject to Paragraphs 20('s) and 21 below, and to 
the fullest extent permitted by law, Tenant shall indemnify, hold Landlord 
harmless from and defend Landlord, its agents and employees against any and 
all claims, losses, costs, damages, expenses or liabilities, including 
without limitation reasonable attorney's fees and costs of defense, for death 
of or any injury or damage to any person or property whatsoever, when such 
death, injury or damage has been caused in part or in whole by the act, 
neglect, fault, or omission of Tenant, its assignees, sublessees, agents, 
servants, employees or invitees or which arises from Tenant's use of the 
Premises or the conduct of Tenant's business. Tenant shall further indemnify, 
hold Landlord harmless from and defend Landlord, it's agents and employees 
against and from any and all claims arising from any breach or default in the 
performance of any obligation on Tenant's part to be performed under the 
terms of this Lease. This indemnification provision shall not require payment 
as a condition precedent to recovery, and Tenant's defense obligation 
hereunder shall include the obligation, upon demand, to defend Landlord 
against any claim or action of the type herein specified by counsel 
reasonably satisfactory to Landlord. In addition, if any person not a party 
to this Lease shall institute any other type of action against Tenant in 
which Landlord, involuntarily and without cause, shall be made a party 
defendant and which is related to this Lease, Tenant shall indemnify, hold 
Landlord harmless from and defend Landlord from all liabilities by reason 
thereof.

     (c) TENANT'S INSURANCE. Tenant hereby agrees to maintain in full force 
and effect at all times during the term of this Lease, at its own expense, 
for the protection of Tenant and Landlord, as their interests may appear, 
policies of insurance which afford the following coverages:

          (i) Workers' Compensation coverage as required by law, including 
     United States Longshoremen and Harborworkers Act (if applicable), 
     together with Employer's Liability coverage with a limit of not less 
     than $1,000,000 per occurrence.

          (ii) Comprehensive General Liability or Commercial General 
     Liability Insurance with respect to the Premises and the operations on

     Host Liquor Liability (or Liquor Liability, if applicable), protection 
     and indemnity (if applicable) and Owned and Non-Owned Automobile 
     Coverage in an amount not less than $1,000,000 per occurrence. The 
     policy for such insurance shall contain the following provisions: (A) 
     severability of interest; (B) cross liability; (C) an endorsement naming 
     Landlord and any other parties in interest designated by Landlord as an 
     additional insured; (D) an endorsement stating, in substance, "such 
     insurance as is afforded by this policy for the benefit of the Landlord 
     and any other additional insured shall be primary as respects to any 
     liability or claims arising out of the occupancy of the Premises by the 
     Tenant, or Tenant's operations and any insurance carried by Landlord, or 
     any other additional insured shall be non-contributory;" (E) with 
     respect to improvements or alterations permitted under this Lease, 
     contingent liability and builder's risk insurance; (F) an endorsement 
     allocating to the Premises the full amount of liability limits required 
     by this Lease; (G) coverage must be on an "occurrence basis;" "Claims 
     Made" forms are not acceptable; and (H) an aggregate limit of no less 
     than $3,000,000 per annum available for occurrences at the Premises, if 
     such policy has an aggregate limit.

          (iii) Insurance providing protection against "All Risks" of 
     physical loss, including without limitation insurance against fire, 
     theft, burglary, structural collapse, sprinkler leakage, earthquake and 
     flood (if required by a lender holding a security interest in the 
     Project), vandalism and malicious mischief, in all amount sufficient to 
     cover the full cost of replacement (with no deductible for depreciation 
     and with the understanding that such amount shall be adjusted not more 
     frequently than on an annual basis) of all improvements and betterments 
     to the Premises, all of Tenant's fixtures, furnishings, equipment, 
     furniture, trade fixtures and other personal property located or used in 
     the Premises and loss of income or extra expense including losses 
     resulting from an interruption in or a failure of the Intrabuilding 
     Network Cabling. All policies of such insurance shall contain no

                                                          LANDLORD'S   TENANT'S

     coinsurance or contribution provisions and shall name Landlord and 
     the lending institution(s), if any, as additional insured's and/or loss 
     payable in accordance with such lender's or lenders' requirements. For 
     the purposes of this subparagraph (iii), the Premises shall consist of 
     the Rentable Area shown in the floor plan attached hereto as Exhibit 
     "A-1," and consist of the cubic space spanning from the floor slab to 
     the bottom surface of the floor slab of the floor immediately above the 
     Premises (the "upper slab"), without any offsets or deductions for 
     columns and other structural portions of the Building or vertical 
     penetrations that are included for the special use of Tenant. Such cubic 
     space shall include the plenum space which is bounded by the lower 
     surface of the upper slab and the suspended ceiling of the Premises. The 
     proceeds of such insurance, so long as this Lease remains in effect, 
     shall be used to repair or replace the improvements, trade fixtures and 
     personal property in the Premises so insured. Upon any termination of 
     this Lease pursuant to Paragraph 14(a) above, the proceeds of such 
     insurance relating to improvements to the Premises shall be the property 
     of Landlord.

          (iv) Loss of income or business interruption insurance providing 
     protection against any peril included within the classification "All 
     Risk," including but not limited to insurance against sprinkler leakage.

     The minimum limit of the coverage provided in division (ii) above shall 
be adjusted upward only at the expiration of each third (3rd) full calendar 
year as follows: Not less than sixty (60) days prior to the relevant 
adjustment date, Landlord shall request such insurance brokerage firm as is 
then placing insurance for Landlord (the "Reviewing Broker") to review 
Tenant's then existing liability insurance coverage, to review the then use 
of the Premises and the claims history with respect thereto and to recommend, 
in writing, the amount of coverage to be carried by Tenant pursuant to 
division (ii). Such recommendation shall be based upon the then use of the 
Premises and the liability claims history with respect to the Premises and 
shall be certified by the Reviewing Broker to be consistent with amounts of 
coverage generally recommended by such Reviewing Broker for similar types of 
tenants or users of property with uses similar to that of the Premises in the 
geographical area which includes the Premises. If the Reviewing Broker shall 
recommend an increase(s) in the amount of coverage then provided by Tenant 
under division (ii), Tenant shall promptly increase its coverage to the 
recommended amount(s). In no event shall there by any reduction in the amount 
of coverage provided by Tenant under division (ii) below the initial amounts 
set forth herein, notwithstanding any recommendation by the Reviewing Broker. 
The failure of the Reviewing Broker to require any additional insurance 
coverage shall not be deemed to relieve Tenant from any obligations under 
this Lease.

     (d) DEDUCTIBLES. Tenant may, with the written consent of Landlord, elect 
to have reasonable deductibles in connection with the policies of insurance 
required to be maintained by Tenant under subparagraph (c)(iii).

     (e) CERTIFICATES OF INSURANCE. Tenant shall deliver to Landlord at least 
thirty (30) days prior to the time such insurance is first required to be 
carried by Tenant, and thereafter at least thirty (30) days prior to the 
renewal date or expiration of each such policy, Certificates of Insurance 
evidencing the above coverage with limits not less than those specified 
above. Such Certificates, with the exception of Workers' Compensation, shall 
add Landlord and each of its partners, and its and their subsidiaries, 
affiliates, partners, officers, directors, agents, employees, lenders and 
other persons or entities designated by Landlord and having an insurable 
interest in the Premises as additional insured and shall expressly provide 
that the interest or same therein shall not be affected by any breach by 
Tenant of any policy provision for which such Certificates evidence coverage. 
Neither Landlord nor any other person or entity named as an additional 
insured pursuant to this subparagraph shall have any obligation under such 
policies, such as payment of premiums, giving of notices and the like. 
Further, all Certificates shall expressly provide that not less than thirty 
(30) days prior unqualified written notice shall be given to Landlord or 
Landlord's lender in the event of material alteration to, non-renewal of, or 
cancellation of the coverages evidenced by such Certificates. Notwithstanding 
the foregoing, Landlord may, at any time, from time to time, inspect and/or 
copy and approve any and all insurance policies required hereunder.

     (f) LANDLORD'S INSURANCE. Landlord shall at all times during the term of 
this Lease maintain in effect a policy or policies of (i) "All Risk" 
insurance, together with sprinkler leakage and vandalism and malicious 
mischief coverage, covering the Building and the Project, including 
Landlord's interest in all tenant improvements in the Premises, and (ii) 
Lessor's "Risk Only" Liability Insurance. Landlord may also, but shall not be 
required to, maintain flood and earthquake insurance with respect to the 
Project, rental interruption insurance assuring that the rent under this 
Lease will be paid to Landlord for a period of not less than twelve (12) 
months if the Premises are destroyed or rendered inaccessible by a risk 
insured against under the foregoing coverage, and any other types of 
insurance that Landlord, in its business judgment, may determine is necessary 
or desirable to obtain. The cost of all such insurance shall be included in 
the Operating Expenses to be reimbursed by Tenant to Landlord pursuant to 
Paragraph 3.

     (g) INCREASE IN COVERAGE. Upon demand, Tenant shall provide Landlord, at 
Tenant's expense, with such increased amount of existing insurance, and such 
other insurance in such limits, as Landlord may require and such other hazard 
insurance as the nature and condition of the Premises may require in the sole 
judgment of Landlord to afford Landlord adequate protection for risks of 
Tenant to be insured hereunder.


                                                          LANDLORD'S   TENANT'S

     (h) NO CO-INSURANCE. If on account of the failure of Tenant to comply 
with the provisions of this Paragraph, Landlord or any additional insured is 
adjudged a coinsurer by its insurance carrier, then any loss or damage 
Landlord or such additional insured shall sustain by reason thereof shall be 
borne by Tenant and shall be immediately paid by Tenant upon receipt of a 
bill therefor and evidence of such loss.

     (i) INSURANCE LIMITS. Landlord makes no representation that the limits 
of liability specified to be carried by Tenant under the terms of this Lease 
are adequate to protect Tenant against Tenant's undertakings under this 
Lease. In the event Tenant believes that any such insurance coverage called 
for under this Lease is insufficient, Tenant shall provide, at its own 
expense, such additional insurance as Tenant deems adequate. In no event 
shall the limits of any coverage maintained by Tenant pursuant to this 
Paragraph 20 be considered as limiting Tenant's liability under this Lease.

     (j) LANDLORD'S NEGLIGENCE. Nothing contained herein shall operate to 
relieve Landlord from any loss, damage, injury, liability, claim, cost or 
expense which it is determined by a court of competent jurisdiction was 
proximately caused by its willful misconduct or its own sole negligence or 
the sole negligence of its agents or employees.

     (k) GENERAL REQUIREMENTS. All insurance required to be carried by Tenant 
hereunder shall be with companies rated A:X, or better, in the then most 
recent edition of Best's Insurance Guide and licensed to provide the relevant 
insurance in the State of California. Such insurance shall be primary 
insurance (and not "excess over") as respects Landlord and any other 
additional insured(s) designated by Landlord and not contributory with any 
other available insurance. All policies or such insurance shall each contain 
an unqualified provision that the insurer will not cancel, deny renewal or 
materially amend the coverage provided by such policy without first giving 
Landlord and any additional insured(s) thirty (30) days' prior written 
notice. All policies and certificates delivered by Tenant pursuant to this 
Paragraph shall contain liability limits not less than those set forth 
herein, shall list the additional insured(s) and shall specify all 
endorsements and special coverages required by this Paragraph. Any insurance 
required to be maintained by Tenant may be maintained by Tenant pursuant to 
so-called "blanket" policies of insurance so long as (i) the Premises is 
specifically identified therein (by rider, endorsement or otherwise) as 
included in the coverage provided, (ii) the limits of the policy arc 
applicable on a "per location" basis to the Premises and (iii) such policies 
otherwise comply with the provision of this Lease. The term "term of this 
Lease" shall mean, for the purposes of this Paragraph, the period commencing 
on the date Tenant is given access to the Premises for any purpose through 
the later of the expiration or termination of the Lease term or the date 
Tenant surrenders physical possession of the Premises to Landlord. With 
respect to the Comprehensive General Liability insurance required to be 
obtained by Tenant under this Lease, the foregoing general requirements are 
Subject to the specific requirements set forth in subparagraph (c)(ii), 
above.

     (l) In the event that Tenant fails to procure, maintain and/or pay for 
at the times and for the durations specified in this Lease, any insurance 
required by this Paragraph, or fails to carry insurance required by any 
governmental requirement, Landlord may (but without obligation to do so) at 
any time or from time to time, and without notice, procure such insurance and 
Tenant agrees to pay the sums so paid by Landlord together with interest 
thereon at the interest rate set forth in Paragraph 37(a) below, and any 
costs or expenses incurred by Landlord in connection therewith, within ten 
(10) days following Landlord's written demand to Tenant for such payment.

21.  WAIVER OF SUBROGATION

     Landlord and Tenant each hereby waives any and all rights of recovery 
against the other, and against any other tenant or occupant of the Building 
and the Project and against the officers, employees, agents, 
representatives, customers and invitees of such other party and of such other 
tenant or occupant of the Building and the Project for loss of or damage to 
such waiving party or its property or the property of others under its 
control, to the extent that such loss or damage is insured against under any 
policy of insurance required to be carried by such waiving party pursuant to 
(the provisions of this Lease (or any other policy of insurance carried by 
such waiving party in lieu thereof) at the time of such loss or damage. The 
foregoing waiver shall be effective whether or not a waiving party shall 
actually obtain and maintain the insurance which such waiving party is 
required to obtain and maintain pursuant to this Lease (or any substitute 
therefor). The policies of insurance which Landlord and Tenant are required 
to maintain under this Lease shall provide that the insurance company shall 
waive all right of recovery by way of subrogation against either Landlord or 
Tenant in connection with any damage covered by the subject policy.

22.  ATTORNEYS' FEES

     In the event of any legal action or proceeding brought by either party 
against the other arising out of this Lease or in which this Lease is 
asserted as a defense, the prevailing party shall be entitled to recover 
from the other party reasonable attorneys' fees incurred in such action in an 
amount determined by the court, in addition to its costs incurred in such 
action, and such amounts shall be included in any judgment rendered in
                                       
                                                          LANDLORD'S   TENANT'S

such action or proceeding. For purposes of this provision, in any unlawful 
detainer or other action or proceeding instituted by Landlord based upon any 
default or alleged default of Tenant hereunder, Landlord shall be deemed the 
prevailing party if (a) judgment is entered in favor of Landlord or (b) prior 
to trial or judgment Tenant shall pay all or any portion of the rent claimed 
by Landlord, eliminate the condition(s), cease the act(s) or otherwise cure 
the omission(s) claimed by Landlord to constitute a default by Tenant 
hereunder. If Landlord becomes involved in any litigation or dispute, 
threatened or actual, by or against anyone not a party to the Lease, but 
arising by reason of or related to any act of omission of Tenant or any of 
the Tenant Parties, Tenant agrees to pay Landlord's reasonable attorneys' 
fees and other costs incurred in connection with the litigation or dispute 
regardless of whether a lawsuit is actually filed.

23.  WAIVER

     No waiver by Landlord of any provision of this Lease or of any breach by 
Tenant hereunder shall be deemed to be a waiver of any other provision 
hereof, or of any subsequent breach by Tenant of the same or any other 
provision. Landlord's consent to or approval of any act by Tenant requiring 
Landlord's consent or approval shall not be deemed to render unnecessary the 
obtaining of Landlord's consent to or approval of any subsequent act of 
Tenant. Furthermore, any custom or practice which may develop between the 
parties in the administration of this Lease shall not be construed to waive 
or lessen the right of Landlord to insist upon the performance by Tenant in 
strict accordance with all of the terms, covenants, agreements, conditions, 
and provisions of this Lease. No act or thing done by Landlord or Landlord's 
agents during the term of this Lease shall be deemed an acceptance of a 
surrender of the Premises, unless done in a writing signed by Landlord. 
Tenant's delivery of keys to any employee or agent of Landlord shall not 
operate as a termination of this Lease or a surrender of the Premises unless 
done pursuant to a written agreement to such effect executed by Landlord. The 
acceptance of any rent by Landlord following a breach of this Lease by Tenant 
shall not constitute a waiver by Landlord of such breach (other than the 
failure to pay the particular rent so accepted) or any other breach unless 
such waiver is expressly stated in a writing signed by Landlord. The 
acceptance of any payment from a debtor in possession, a trustee, a receiver 
or any other person acting on behalf of Tenant or Tenant's estate shall 
not waive or cure a default under Paragraph 26(A)(vi) or waive the 
provisions of Paragraphs 16 or 25.

24.  NOTICES

     All notices, requests, payments, consents or approvals ("notices") which 
Landlord or Tenant may be required, or may desire, to serve on the other 
shall be in writing and may be served, by personal service or as an 
alternative to personal service, by mailing the same by registered or 
certified mail, postage prepaid and return receipt requested, addressed as 
set forth in Item 13 of the Basic Lease Provisions, or addressed to such 
other address or addresses as either Landlord or Tenant may from time to time 
designate to the other in the manner provided for herein. All notices shall 
be deemed effective upon receipt. If personally delivered, notices shall be 
deemed received at the time of delivery. If any notice is sent by mail, the 
same shall be deemed delivered and received on the date of receipt or refusal 
indicated on the return receipt. Any notice provided for herein may also be 
sent by facsimile transmission or by any reputable overnight courier so long 
as written confirmation of delivery of such notice is obtained by the 
sender. In either of these cases, a confirmation copy of such notice shall be 
sent by registered or certified mail, return receipt requested, and such 
notice shall be deemed to be received one day after it is sent.

25.  INSOLVENCY OR BANKRUPTCY

     In no event shall this Lease be assigned or assignable by operation of 
law and in no event shall this Lease be an asset or Tenant in any 
receivership, bankruptcy, insolvency, or reorganization proceeding.

26.  DEFAULTS AND REMEDIES

     (a) The occurrence of any of the following shall constitute a material 
default and breach of this Lease by Tenant:

         (i)   Any failure by Tenant to pay the rent or to make any other 
     payment required to be made by Tenant hereunder at the time specified for 
     payment. Landlord shall give Tenant three (3) days' written notice of any 
     such default, which notice shall be in lieu of, and not in addition to, 
     any notice required under Section 1161, ET SEQ., of the California Code 
     of Civil Procedure, as amended;

         (ii)  The abandonment of the Premises by Tenant. Abandonment is 
     herein defined to include, but is not limited to, any absence by Tenant 
     from the Premises for five (5) days or longer, without notice from 
     Landlord being required and regardless of whether Tenant is otherwise 
     in default under this Lease;
                                       
                                                          LANDLORD'S   TENANT'S

                                      -19-

<PAGE>

         (iii) Any failure by Tenant to observe and perform any other 
     provision of this Lease to be observed or performed by Tenant, where such 
     failure continues for ten (10) days (except where a different period of 
     time is specified in this Lease) after written notice by Landlord to 
     Tenant; provided, however, that any such notice shall be in lieu of, and 
     not in addition to, any notice required under Section 1161, ET SEQ., of 
     the California Code of Civil Procedure, as amended. If the nature of such 
     default is such that the same cannot reasonably be cured within such ten 
     (10) day period, Tenant shall not be deemed to be in default if Tenant 
     shall within such period commence such cure and thereafter diligently 
     prosecute the same to completion;

         (iv)  Tenant makes or has made or furnishes or has furnished any 
     warranty, representation or statement to Landlord in connection with this 
     Lease, or any other agreement to which Tenant and Landlord are parties, 
     which is or was false or misleading in any material respect when made or 
     furnished;

         (v)   Subject to the provisions of Paragraph 16(h) above, any 
     substantial portion of the assets of Tenant is transferred, or any 
     material obligation is incurred by Tenant, unless such transfer or 
     obligation is incurred in the ordinary course of Tenant's business, 
     or in good faith for fair equivalent consideration, or with Landlord's 
     consent; and/or

         (vi)  The making by Tenant of any general assignment for the benefit 
     of creditors; the filing by or against Tenant of a petition to have 
     Tenant adjudged a bankrupt or of a petition for reorganization or 
     arrangement under any law relating to bankruptcy (unless, in the case 
     of a petition filed against Tenant, the same is dismissed within sixty 
     (60) days); the appointment of a trustee or receiver to take possession 
     of substantially all of Tenant's assets located at the Premises or of 
     Tenant's interest in this Lease, where possession is not restored to 
     Tenant within sixty (60) days; the attachment, execution or other 
     judicial seizure of substantially all of Tenant's assets located at the 
     Premises or of Tenant's interest in this Lease, where such seizure is not 
     discharged within sixty (60) days; or Tenant's convening of a meeting of 
     its creditors or any class thereof for the purpose of effecting a 
     moratorium upon or composition of its debts.

     (b) In the event of any such default by Tenant, then in addition to any 
other remedies available to Landlord at law or in equity, Landlord shall have 
the immediate option to terminate this Lease and all rights of Tenant 
hereunder by giving written notice of such intention to terminate. In the 
event that Landlord shall elect to so terminate this Lease then Landlord may 
recover from Tenant:

         (i)   the worth at the time of award of any unpaid rent which had 
     been earned at the time of such termination; plus

         (ii)  the worth at the time of award of the amount by which the 
     unpaid rent which would have been earned after termination until the 
     time of award exceeds the amount of such rental loss which Tenant 
     proves reasonably could have been avoided; plus

         (iii) the worth at the time of award of the amount by which the 
     unpaid rent for the balance of the term of this Lease after the time of 
     award exceeds the amount of such rental loss that Tenant proves 
     reasonably could have been avoided; plus

         (iv)  any other amount necessary to compensate Landlord for all the
     detriment proximately caused by Tenant's failure to perform its obligations
     under this Lease or which in the ordinary course of things would be likely
     to result therefrom including any amount expended by Landlord to mitigate
     damages; plus

         (v)   the unamortized value of the Building Standard Work (as 
     described in Exhibit "B") made to the Premises, calculated by reference 
     to the length of the term of the Lease that would have remained had the 
     Lease not been terminated; plus

         (vi)  the amount of rent, if any, that is postponed or abated, as 
     well as the amount of any other rent or operating concession, any lease 
     take over obligation assumed by Landlord, any lease subsidy paid by 
     Landlord or any other bonus, lease cancellation payment, inducement or 
     concession for Tenant's entering into this Lease; and

         (vii) at Landlord's election, such other amounts in addition to or 
     in lieu of the foregoing as may be permitted from time to time by 
     applicable California law.

     (c) As used in subparagraphs (b)(i) and (b)(ii) above, the "worth at the 
time of award" is computed by allowing interest at the rate determined 
pursuant to Paragraph 37 below. As used in subparagraph (b)(iii) above, the 
"worth at the time of award" is computed by discounting such amount at the 
discount rate of the Federal Reserve Bank of San Francisco at the time of 
award plus one percent (1%).

     (d) In the event of any default by Tenant, Landlord shall also have the 
right, with or without terminating this Lease, to re-enter the Premises and 
remove all persons and property from the Premises. Such property may be 
removed and stored in a public warehouse or elsewhere at the cost of and for 
the account of Tenant, all in accordance with applicable California law.

     (e) In the event of the abandonment of the Premises by Tenant or in the 
event that Landlord shall elect to re-enter as provided above or shall take 
possession of the Premises pursuant to legal proceedings or pursuant to any 
notice provided by law, then if Landlord does not elect to terminate this 
Lease as provided in this Paragraph 26, Landlord may from time to time, 
without terminating this Lease, either recover all rental as it becomes due 
or relet the Premises or any part thereof for such term or terms and at such 
rental or rentals and upon such other terms and conditions as Landlord in its 
sole discretion may deem advisable, with the right to make alterations and 
repairs to the Premises. Election by Landlord to proceed pursuant to this 
subparagraph shall be made upon written notice to Tenant and shall be deemed 
an election of the remedy described in California Civil Code Section 
1951.4 and, unless Landlord relets the Premises, Tenant shall have the right 
to sublet or assign subject to the prior written consent of Landlord. Such 
consent shall not be unreasonably withheld and shall be subject to all of 
the terms and provisions of Paragraph 16.

     (f) In the event that Landlord shall elect to so relet, then rentals 
received by Landlord from such reletting shall be applied: first, to the 
payment of any indebtedness other than rent due hereunder from Tenant to 
Landlord; second, to the payment of any cost of such reletting; third, to the 
payment of the cost of any alterations and repairs to the Premises; fourth, 
to the payment of rent due and unpaid hereunder; and the residue, if any, 
shall be held by Landlord and applied in payment of future amounts as the 
same may become due and payable hereunder. Should the rent for such 
reletting, during any month for which the payment of rent is required 
hereunder, be less than the rent payable during that month by Tenant 
hereunder, then Tenant shall pay such deficiency to Landlord immediately upon 
demand therefor by Landlord. Such deficiency shall be calculated and paid 
monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs 
and expenses incurred by Landlord in such reletting or in making such 
alterations and repairs not covered by the rentals received from such 
reletting.

     (g) No re-entry, removal of property or taking possession of the 
Premises by Landlord pursuant to this Paragraph 26 shall be construed as an 
election to terminate this Lease unless a written notice of such intention be 
given to Tenant or unless the termination thereof be decreed by a court of 
competent jurisdiction. Furthermore, neither Landlord's acts of maintenance 
or preservation NOR its efforts to relet NOR the appointment of a receiver to 
collect rents shall constitute a termination of Tenant's right to possession 
unless a written notice of such intention is provided by Landlord to Tenant. 
Notwithstanding any reletting without termination by Landlord because of any 
default by Tenant, Landlord may at any time after such reletting elect to 
terminate this Lease for any such default.

     (h) In any action for unlawful detainer commenced by Landlord against 
Tenant by reason of any default hereunder, the reasonable rental value of the 
Premises for the period of the unlawful detainer shall be the amount of rent 
reserved in this Lease for such period, unless Landlord or Tenant shall prove 
to the contrary by competent evidence. The rights and remedies reserved to 
Landlord herein, including those not specifically described, shall be 
cumulative and, except as otherwise provided by California statutory law in 
effect at the time, Landlord may pursue any or all of such rights and 
remedies, or any other right available at law or equity, at the same time or 
otherwise. Without limitation, Tenant acknowledges that Tenant's failure to 
timely comply with the requirements of Paragraph 18(a) may result in a 
lender refusing to loan Landlord funds or a buyer refusing to purchase the 
Building or Project on favorable terms (or at all), causing Landlord 
substantial monetary damages.

     (i) All covenants and agreements to be performed by Tenant under this 
Lease shall be performed by Tenant at Tenant's sole cost and expense and 
without any abatement of rent. If Tenant fails to pay any sum of money, other 
than rent, required to be paid by it or fails to perform any other act on its 
part to be performed, and such failure continues beyond any applicable grace 
period set forth in the Paragraph providing for such obligation (or if no 
grace period is set forth in such Paragraph, then the applicable grace 
period pursuant to this Paragraph 26), then in addition to any other remedies 
provided herein Landlord may but shall not be obligated so to do, without 
curing such default or waiving or releasing Tenant from any of its 
obligations, make any such payment or perform any such other act on Tenant's 
part, including the removal of any offending signs. Landlord's election to 
make any such payment or perform any such act on Tenant's part shall not give 
rise to any responsibility of Landlord to continue making the same or similar 
payments or performing the same or similar acts. Tenant shall, within ten 
(10) days after written demand therefor by Landlord, reimburse Landlord for 
all sums so paid by Landlord and all necessary incidental costs, together 
with interest thereon at the rate determined under Paragraph 37, accruing 
from the date of such payment by Landlord; and Landlord shall have the same 
rights and remedies in the event of failure by Tenant to pay such amounts as 
Landlord would have in the event of a default by Tenant in payment of rent.

     (j) Tenant hereby waives, for itself and all persons claiming by and 
under Tenant, all rights and privileges which it might have had under any 
present or future law, to redeem the Premises or to continue the Lease after 
being dispossessed or ejected from the Premises.

27.  HOLDOVER

     Tenant shall surrender possession of the Premises immediately after 
the expiration of the Lease term or termination of the Lease. If Tenant or 
anyone claiming under Tenant holds over after the expiration or earlier 
termination of the term hereof without the express written consent of 
Landlord, Tenant shall (a) become a tenant at sufferance only at the greater 
of (i) two hundred percent (200%) of the Basic Annual Rent then in effect, or 
(ii) two hundred percent (200%) of the then prevailing market rent then in 
effect upon the date of such expiration or earlier termination (subject to 
adjustment as is provided in Paragraphs 2 and 3 hereof and prorated on a 
daily basis), and otherwise upon the terms, covenants and conditions herein 
specified, (including, without limitation, the payment of Additional Rent) so 
fir as applicable, (b) pay all damages sustained by Landlord by reason of 
such holding over and (c) indemnify, defend and hold Landlord harmless from and 
against any loss or liability resulting from such holding over, including, 
but not limited to, any amounts required to be paid to any tenant or 
prospective tenant who was to have occupied the Premises after said 
termination or expiration and any related attorneys' fees and brokerage 
commissions. Acceptance by Landlord of rent after such expiration or earlier 
termination shall not constitute a consent to a holdover hereunder, but shall 
create only a month-to-month tenancy terminable at the end of any calendar 
month by not less than ten (10) days written notice given by either party to 
the other party. Further, no payment of money by Tenant to Landlord after the 
etrmination of this Lease by Landlord, or after the giving of any notice of 
termination to Tenant by Landlord which Landlord is entitled to give Tenant 
under this Lease, shall reinstate, continue or extend the term of this Lease 
or shall affect any such notice given to Tenant prior to the payment of such 
money, it being agreed that after the service of such notice or the 
commencement of any suit by Landlord to obtain possession of the Premises, 
Landlord may receive and collect when due any and all payments owed by Tenant 
under the Lease, and otherwise exercise its rights and remedies. The making 
of any such payments by Tenant shall not waive such notice, or in any manner 
affect any pending suit or judgment obtained. The foregoing provisions of 
this Paragraph are in addition to and do not affect Landlord's right of 
re-entry or any other rights of Landlord hereunder or as otherwise provided 
by law.

28.  CONDITION OF PREMISES

     Tenant acknowledges that neither Landlord nor any agent of Landlord has 
made any representation or warranty with respect to the Premises, the 
Building or the Project or with respect to the suitability of any part of the 
Project for the conduct of Tenant's business. The taking of possession of the 
Premises by Tenant shall conclusively establish that the Premises and the 
Building were at such time in good and sanitary order, condition and repair. 
Landlord and its agents shall not be liable for any latent defect in the 
Premises or in the Building. Tenant shall give prompt notice to Landlord in 
case of fire or accidents in the Premises or in the Building, or of defects 
therein or in the fixtures and equipment.

29.  QUIET POSSESSION

     Upon Tenant's paying the rent hereunder and observing and performing all 
of the covenants, conditions and provisions on Tenant's part to be observed 
and performed hereunder, Tenant shall have quiet possession of the Premises 
for the entire term hereof, subject to all the provisions of this Lease.

30.  TENANT'S SIGNS

     (a) Tenant may, at its sole cost and expense, place its signs displaying 
its logo and graphics on the entrance doors to the Premises and in hallways 
or elevator lobbies on floors wholly leased by Tenant. On partial floors 
leased by Tenant, Tenant, at its sole cost and expense, may place its signs 
on entrance doors to the Premises provided the number, size, color, style, 
material and location of such signs conform to Landlord's graphics program 
for the Building and Landlord shall place directional signs to the Premises, 
at Tenant's expense, at a location determined by Landlord.

     (b) Landlord at its own cost and expense shall place a directory board 
in the Building lobby. Landlord shall cause Tenant's name to be affixed 
thereto, at Tenant's cost.

     (c) Unless specifically set forth to the contrary in an addendum to 
this Lease, Tenant shall not place any sign on the exterior of the Building, 
or within the Building if such sign may be seen from outside of (he Building 
or on any Building sign monument or other device constructed for the 
placement of tenant signs.

     (d) All Tenant signs installed by Landlord or Tenant shall comply with 
all applicable requirements of all governmental authorities having 
jurisdiction and shall be installed in a good and workmanlike manner. Such 
signs shall be maintained and kept in good repair at Tenant's sole cost and 
expense.

31.  CONFLICT OF LAWS

     This Lease shall be governed by and construed pursuant to the laws of 
the State of California, and the venue of any action or proceeding under 
this Lease shall be Orange County, California.

32.  COMMON FACILITIES; PARKING

     Tenant shall have the non-exclusive right, in common with Landlord and 
other tenants and occupants of the Project and their employees, agents and 
business visitors, to the use of all common facilities which constitute a 
part of the Project, subject to such reasonable rules and regulations 
relating to such use as Landlord may from time to time establish. Common 
facilities located within the Building include any building lobby, elevators, 
rest rooms, stairways and stairwells, elevator lobbies and all common 
entrances, corridors, passageways and serviceways which are not located 
within the Premises of Tenant or the premises of another tenant of the 
Building. Common facilities located outside of the Building include 
landscaping, hardscaping, a parking structure (the "Project Parking 
Structure"), all sidewalks, driveways, vehicle and pedestrian entrances and 
accessways, loading docks, truck tunnels, truck parking and truck turn-around 
areas, vehicle and pedestrian ramps serving the Project, and any pedestrian 
walkway connecting the Building and the Project Parking Structure. The common 
facilities located outside of the Building but included within the 
definition of the Project are those areas which are depicted on Exhibit 
"A-3" attached hereto. Landlord may make changes at any time and from time to 
time to the common facilities, without any liability to Tenant, and no such 
change shall entitle Tenant to any abatement of rent. Landlord shall at all 
times have the sole and exclusive control of the common facilities.

     Tenant shall keep all common facilities free and clear of any 
obstructions created or permitted by Tenant or resulting from Tenant's 
operations and shall not conduct an assembly on the common facilities without 
Landlord's prior consent. Nothing herein shall affect the right of Landlord 
at any time to remove any persons not authorized to use the common facilities 
or to prevent the use of such facilities by unauthorized persons. Landlord 
reserves the right, from time to time, to (A) make alterations in or 
additions to file common facilities, including without limitation, 
constructing new structures or changing the location, size, shape and/or 
number of the driveways, entrances, parking spaces, parking areas, loading 
and unloading areas, landscape areas and walkways, (B) close temporarily any 
of the common facilities of the Project for maintenance purposes as long as 
reasonable access to the Premises remains available, (C) designate property 
to be included in or eliminate property from the common facilities of the 
Project, and (D) use the common facilities of the Project while engaged in 
making alterations in or additions or repairs to the Project.

     Tenant shall have such parking rights in and to parking contracts for 
spaces located in the Project Parking Structure as are set forth in the 
Parking Agreement attached hereto as Exhibit "E." All agreements by Tenant 
and Tenant's employees for monthly usage of spaces shall be made directly 
with the operator of the Project Parking Structure.

33.  SUCCESSORS AND ASSIGNS

     Except as otherwise provided in this Lease, all of the covenants, 
conditions and provisions of this Lease shall be binding upon and shall inure 
to the benefit of the parties hereto and their respective heirs, personal 
representatives, successors and assigns.

34.  BROKERS

     Tenant warrants that it has had no dealings with any real estate broker 
or agent in connection with the negotiation of this Lease, excepting only 
the broker named in Item 10 of the Basic Lease Provisions ("Broker"), and 
that it knows of no other real estate broker or agent who is or might be 
entitled to a commission in connection with this Lease. Landlord covenants 
and agrees to pay all real estate commissions due in connection with this 
Lease to Broker as follows: (i) Landlord shall pay to Broker an amount equal 
to four percent (4%) of Basic Annual Rent and Additional Rent for the first 
twelve (12) months of the term of this Lease within ten (10) days of full 
execution and delivery or this Lease, and (ii) provided Tenant has not been 
in default of the Lease, Landlord shall pay to Broker an amount equal to 
four percent (4%) of Basic Annual Rent and Additional Rent for the second 
twelve (12) months of the term of this Lease within ten (10) days of the 
end of the seventeenth (17th) month of the term. Tenant agrees to pay and 
hold Landlord harmless from and defend Landlord against any cost, expense or 
liability for any compensation claimed by any broker, finder or agent other 
than Broker employed or claiming to have been employed by Tenant in 
connection with this Lease or with the negotiation of this Lease. Landlord 
and Tenant acknowledge that payment shall not be a condition precedent to 
recovery upon the foregoing indemnification provision.

35.  NAME

     Tenant shall not, without the written consent of Landlord, use the 
name, insignia or logotype of the Building or the Project for any purpose 
other than as the address of the business to be conducted by Tenant in the 
Premises, and in no event shall Tenant acquire any rights in or to such name, 
insignia and/or logotype. Furthermore, Tenant shall not use any picture of 
the Building or Project in its advertising, stationery or in any other 
manner. Tenant shall, when referring to the Building, refer to the Building 
by the name or address assigned thereto, from time to time, by Landlord and 
shall refer to its location as the "the Offices at South Coast Plaza." 
References to the Building and its location shall not be made by Tenant in 
any other manner. Landlord expressly reserves the right, in its sole and 
absolute discretion, at any time to change the name, insignia, logotype or 
street address of the Building or the Project without in any manner being 
liable to Tenant.

36.  EXAMINATION OF LEASE

     Submission of this instrument for examination, negotiation or signature 
by Tenant does not constitute an offer to lease or a reservation of the 
Premises for Tenant or an option for Tenant to lease the Premises, and it is 
not effective as a Lease or otherwise until at least one counterpart, duly 
executed by authorized persons of Landlord and Tenant, has been delivered to 
each party thereto. Without limiting the generality of the foregoing, Tenant 
acknowledges that this Lease and any material amendments hereto are subject 
to the approval of Landlord's lender with respect to the Project. Promptly 
upon execution of this Lease by Tenant, Landlord shall submit the same to its 
lender for approval. Delivery by Landlord to Tenant of a copy of this Lease 
or of any amendment hereto fully executed by Landlord and Tenant shall 
constitute notice to Tenant that Landlord has obtained the approval of its 
lender with respect to this Lease or such amendment.

37.  INTEREST ON TENANT'S OBLIGATIONS; LATE CHARGE

     (a) Any amount due from Tenant to Landlord which is not paid when due 
shall bear interest at the maximum rate per annum which Landlord is permitted 
by law to charge, from the date such payment is due until paid, but the 
payment of such interest shall not excuse or cure any default by Tenant under 
this Lease. Such rate shall remain in effect after the occurrence of any 
breach or default hereunder by Tenant to and until payment of the entire 
amount due.

     (b) In the event Tenant is more than ten (10) days late in paying any 
installment of rent due under this Lease, Tenant shall pay Landlord a late 
charge equal to five percent (5%) of the delinquent installment of rent, 
provided that in no event shall the amount of such late charge be less than 
One Hundred Dollars ($100.00). The parties agree that it would be impractical 
or extremely difficult to fix Landlord's actual damages due to a late payment 
by Tenant and that the amount of such late charge represents a reasonable 
estimate of the cost and expense that would be incurred by Landlord in 
processing each delinquent payment of rent by Tenant and that such late 
charge shall be paid to Landlord as liquidated damages for each delinquent 
payment pursuant to California Civil Code Section 1671. The parties further 
agree that the payment of late charges and the payment of interest provided 
for in subparagraph (a) above are distinct and separate from one another in 
that the payment of interest is to compensate Landlord for the use of 
Landlord's money by Tenant, while the payment of a late charge is to 
compensate Landlord for the additional administrative expense incurred by 
Landlord in handling and processing delinquent payments. It is understood 
that the payment of any late charge by Tenant and the acceptance thereof by 
Landlord shall not be deemed a waiver by Landlord of its rights regarding any 
default by Tenant under this Lease.

38.  TIME

     Time is of the essence of this Lease with respect to the performance of 
every provision of this Lease in which time of performance is a factor.

39.  DEFINED TERMS AND MARGINAL HEADINGS

     The words "Landlord" and "Tenant" as used herein shall each include the 
plural as well as the singular and, when applicable, shall refer to actions 
taken by their respective representatives. If more than one person is named 
as Tenant the obligations of such persons are joint and several. The headings 
to the Paragraphs of this Lease are not a part of this Lease and shall have 
no effect upon the construction or interpretations of any part hereof.

40.  PRIOR AGREEMENTS; SEPARABILITY

     This Lease and the exhibits and any addenda hereto contain all of the 
agreements of the parties hereto with respect to any matter covered or 
mentioned in this Lease, and no prior agreement, understanding or 
representation pertaining to any such matter shall be effective for any 
purpose. No provision of this Lease may be amended or added to except by an 
agreement in writing signed by the parties hereto or their respective 
successors in interest. No verbal agreement or implied covenant shall be held 
to vary the terms hereof, any statute, law or custom to the contrary 
notwithstanding. No employee or agent of Landlord shall have authority, by 
letter, memorandum or other written communication, to amend, vary or delete 
any provision of this Lease or any exhibit hereto, unless such written 
instrument bears the signature of Landlord. If any term or provision of this 
Lease the deletion of which would not adversely affect the receipt of any 
material benefit by either party hereunder shall be held invalid, illegal or 
unenforceable to any extent, the remainder of this Lease shall not be 
affected thereby and each term and provision of this Lease shall be valid and 
enforceable to the fullest extent permitted by law.

41.  TRAFFIC AND ENERGY MANAGEMENT

     (a) Tenant and its employees shall comply with South Coast Air Quality 
Management District Regulation 15 and any other environmental regulation 
and/or program now or hereafter applicable to the Project. Landlord and 
Tenant agree to cooperate and use their best efforts to participate in 
governmentally mandated and voluntary traffic management programs generally 
applicable to businesses located in Costa Mesa, California or to the Project 
and, initially, shall encourage and support van and car pooling by office 
workers and service employees and shall encourage and support staggered and 
flexible working hours for employees to the fullest extent permitted by the 
requirements of Tenant's business. Neither this Paragraph nor any other 
provision in this Lease, however, is intended to or shall create any rights 
or benefits in any other person, firm, company, governmental entity or the 
public.

     (b) Landlord and Tenant agree to cooperate and use their best efforts to 
comply with any and all guidelines or controls imposed upon either Landlord 
or Tenant by federal or state governmental organizations or by any energy 
conservation association to which Landlord is a party concerning energy 
management.

     (c) All costs, fees and assessments and other charges paid by Landlord 
to any governmental authority or voluntary association in connection with any 
program of the types described in this Paragraph, and all costs and fees paid 
by Landlord to any governmental authority, voluntary association or third 
party pursuant to or to implement any such program, shall be included in 
Operating Expenses for the purpose of Paragraph 3, whether or not 
specifically listed in such Paragraph. Any breach by Tenant of any of its 
covenants in this Paragraph 41 may result in penalties or fees being assessed 
against Landlord or the Project. These penalties or fees shall not be part of 
Building Operating Expenses or Project Operating Expenses but instead shall 
be payable by Tenant on demand of Landlord.

42.  CORPORATE/PARTNERSHIP/TRUST AUTHORITY

     Each individual executing this Lease on behalf of Landlord and Tenant 
represents and warrants that the execution and delivery of this Lease on 
behalf of the party for whom such person is executing is duly authorized, 
that the or she is authorized to execute and deliver this Lease and that this 
Lease is binding upon such party in accordance with its terms. If Tenant is a 
corporation, Tenant shall, within ten (10) days after execution of this 
Lease, deliver to Landlord a certified copy of a resolution of the Board of 
Directors of Tenant or any executive committee thereof authorizing or 
ratifying the execution of this Lease. Failure of Tenant to provide such 
resolution shall not, however, relieve Tenant of its obligations pursuant to 
this Lease. If Tenant is a partnership or trust, Tenant shall deliver those 
certificates or written assurances from the partnership or trust as Landlord 
may reasonably request.

43.  NO LIGHT, AIR OR VIEW EASEMENT

     Any diminution or shutting off of light, air or view by any structure 
which may be erected on lands adjacent to the Project shall in no way affect 
this Lease, abate any payment owed by Tenant under the Lease, or otherwise 
impose any liability on Landlord.

44.  NON-DISCLOSURE OF LEASE TERMS

     Landlord and Tenant agree that the terms of this Lease are confidential 
and constitute proprietary information of the parties hereto. Disclosure of 
the terms hereof could adversely affect the ability of Landlord to negotiate 
with other tenants. Each of the parties hereto agrees that such party, and 
its respective partners, officers, directors, employees, agents, real estate 
brokers and sales persons and attorneys, shall not disclose any

of the material terms and conditions of this Lease to any other person 
without the prior written consent of the other party hereto except pursuant 
to an order of a court of competent jurisdiction. Provided, however, that 
Landlord may disclose the terms hereof to any lender now or hereafter having 
a lien on Landlord's interest in the Project or any portion thereof, and 
either party may disclose the terms hereof to its respective independent 
accountants who review its respective financial statements or prepare its 
respective tax returns, to any prospective transferee of all or any portions 
of their respective interests hereunder (including a prospective sublessee or 
assignee of Tenant), to any lender or prospective lender to such party, to 
any governmental entity, agency or person to whom disclosure is required by 
applicable law, regulation or duty of diligent inquiry and in connection with 
any action brought to enforce the terms of this Lease, on account of the 
breach or alleged breach hereof or to seek a judicial determination of the 
rights or obligations of the parties hereunder.

45.  FORCE MAJEURE

     Any covenants, conditions, provisions or agreements on the part of 
Landlord to perform any act or thing for the benefit of Tenant shall not be 
deemed breached if Landlord is unable to furnish or perform the same by 
virtue of a strike, lockout, laws, rules, orders, ordinances, directions, 
regulations or requirements of any federal, state, county or municipal 
authority, labor trouble or any other cause whatsoever beyond Landlord's 
control, nor shall Tenant's rent be abated by reason of such inability on the 
part of Landlord. Whenever under the provisions of this Lease, Landlord is 
required or agrees to take certain actions, Landlord's obligation shall be 
deemed fulfilled if Landlord causes such action to be taken by any other 
person.

46.  MISCELLANEOUS

     (a) At the expiration or earlier termination of this Lease, Tenant shall 
execute, acknowledge and deliver to Landlord, within five (5) days after 
written demand from Landlord to Tenant, any quitclaim deed or other document 
which may be reasonably requested by any reputable title insurance company to 
remove this Lease as a matter affecting title to the Premises on a 
preliminary title report or title policy issued with respect to the Project.

     (b) Tenant acknowledges that the exterior demising walls of the Premises 
and the area between the finished ceiling of the Premises and the slab of 
the Building floor thereabove have not been leased to Tenant and the use 
thereof together with the right to install, maintain, use, repair and replace 
pipes, ducts, conduits and wires leading through, under or above the Premises 
in locations which will not materially interfere with Tenant's use of the 
Premises are hereby reserved by Landlord.

     (c) All amounts payable hereunder shall be paid in lawful money of the 
United States which shall be legal tender at the time of payment. When no 
other time is stated herein for payment, payment of any amount due from 
Tenant to Landlord hereunder shall be made within ten (10) days after 
Tenant's receipt of Landlord's invoice or statement therefor.

     (d) Tenant shall, upon written request by Landlord, amend this Lease in 
any manner reasonably requested by any actual or prospective ground lessor of 
or lender to Landlord, provided that any such amendment shall not materially 
impair any rights or remedies of Tenant hereunder.

     (e) LANDLORD AND TENANT EACH ACKNOWLEDGES THAT IT HAS HAD THE ADVICE OF 
COUNSEL OF ITS CHOICE WITH RESPECT TO ITS RIGHTS TO TRIAL BY JURY UNDER THE 
CONSTITUTIONS OF THE UNITED STATES AND THE STATE OF CALIFORNIA. EACH PARTY 
EXPRESSLY AND KNOWINGLY WAIVES AND RELEASES ALL SUCH RIGHTS TO TRIAL BY JURY 
IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER PARTY AGAINST THE 
OTHER ON ANY MATTERS ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, 
TENANT'S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM FOR INJURY OR 
DAMAGE.

Tenant.

     (h) Neither this Lease nor any memorandum hereof shall be recorded by

action with respect to which indemnification may be claimed by the 
indemnified party against the indemnifying party under such provisions or 
(ii) the date on which any claim or action for which indemnification may be 
claimed under such provision is fully and finally resolved and, if 
applicable, any compromise thereof or judgment or award thereon is paid in

the indemnifying party for any amounts paid by the indemnified party in 
compromise thereof or upon a judgment or award thereon and in defense of such 
action or claim, including reasonable attorneys' fees incurred.

     (j) In no event shall the review, approval, inspection or examination by 
Landlord of any item to be reviewed, approved, inspected or examined by 
Landlord under the terms of this Lease be deemed to be an approval of, or 
representation or warranty as to, the adequacy, accuracy, sufficiency or 
soundness of any such item or the quality or suitability of such item for 
its intended use. Any such review, approval, inspection or examination by 
Landlord shall be for the sole purpose of protecting Landlord's interests in 
the Building and the Project under this Lease, and no third parties shall 
have any rights pursuant thereto.

     (k) The obligations of Landlord herein are intended to be binding only 
on the property of the entity acting as Landlord and shall not be personally 
binding, nor shall any resort be had to the private properties of the general 
partners thereof or any employee or agent of Landlord. Subject to the 
provisions of Paragraph 18 to the contrary, any lien obtained to enforce any 
judgment obtained by Tenant against Landlord and any levy of execution 
thereon shall be subject and subordinate to any lien, mortgage or deed of 
trust to which Paragraph 18 applies or may apply.

tenants of the Building and the area occupied by any mechanical, heating, 
ventilating and air conditioning equipment which serves the Building but 
Which is located outside thereof.

     (b) As to each floor of the Building on which space is or will be 
leased to more than one tenant, Rentable Area attributable to each such lease 
shall be determined by BOMA provided that the Rentable Area of the Premises 
shall be measured from the exterior of all walls separating such premises 
from any public corridors or other public areas on such floor, and the 
centerline of all walls separating such premises from other areas leased or 
to be leased to other tenants on such floor, and provided further that the 
Rentable Area of the Building shall include all of (and the Rentable Area of 
the Premises therefore shall include a portion of) (i) the area covered by

                            WORK LETTER AGREEMENT 
                             [TENANT CONSTRUCTS]

     In connection with the lease to which this Work Letter is attached (the 
"Lease"), Landlord and Tenant hereby agree to the terms and conditions set 
forth in this Work Letter relating to the construction of the tenant 
improvements in the Premises ("Tenant's Work"). This Work Letter is 
essentially organized chronologically and addresses the issues of the 
construction of the Premises, in sequence, as such issues will arise during 
the actual construction of the Premises. All capitalized terms used but not 
defined herein shall have the meanings given such terms in the Lease.

     1.  GENERAL.

         (a) The purpose of this Agreement is to set forth how Tenant's Work 
(as defined in Paragraph 5 below) in the Premises is to be constructed, who 
will undertake the construction of Tenant's Work, who will pay for the 
construction of Tenant's Work, and the time schedule for completion of the 
construction of Tenant's Work.

         (b) Except as defined in this Agreement to the contrary, all terms 
utilized in this Agreement shall have the same meanings ascribed to them in 
the Lease. When services, consents or approvals are to be provided by or on 
behalf of Landlord, the term "Landlord" shall include Landlord's agents, 
contractors, employees and affiliates.

         (c) The provisions of the Lease, except where clearly inconsistent or
inapplicable to this Agreement, are incorporated into this Agreement.

         (d) Tenant's Work shall be constructed pursuant to this Agreement by 
Tenant and at Tenant's sole expense.

     2.  COMMENCEMENT DATE. The "Commencement Date" of the Lease shall be as
determined pursuant to Item 8 of the Basic Lease Provisions of the Lease
and this Paragraph 2. That date has been determined based upon the
following:

         (a) DESIGN PERIOD. As provided in Paragraph 3(b) below, Landlord 
shall provide to Tenant (i) the Base Building Plans (as defined in Paragraph 
3.B. below) for the Building and the Premises sufficient to allow Tenant to 
prepare the Working Drawings (as defined in Paragraph 3(d) below) and (ii) 
all rules, regulations, instructions and procedures promulgated by Landlord 
with respect to tenant design and/or construction in the Building (the 
"Building Requirements"). Tenant shall submit for Landlord's approval the 
Space Plan for Tenant's Work in accordance with Paragraph 3(c) below. 
Subsequent to approval of the Space Plan for Tenant's Work and pursuant to 
the terms of Paragraph 3 below, Tenant shall prepare and submit for 
Landlord's approval the Working Drawings, the Engineering Drawings (as 
defined in Paragraph 3(e) below), and the Final Plans (as defined in 
Paragraph 3(f) below), and shall also prepare and submit for Landlord's 
approval a schedule of special finishes required by Tenant. Tenant shall 
thereafter obtain all governmental approvals and permits required for Tenant 
to commence Tenant's Work.

         (b) CONSTRUCTION AND MOVE-IN PERIOD. Landlord shall deliver to 
Tenant and its Contractor (as defined below) access to the Premises (and any 
other required portions of the Building and the Project) commencing as set 
forth in Paragraph 1 of the Lease Tenant shall complete all Tenant's Work in 
Compliance with all applicable laws, statutes, codes, rules and regulations 
(collectively, "Laws"). Tenant shall also obtain the appropriate permits 
necessary to allow Tenant to commence to construct Tenant's Work continuously 
and without interruption. Such period includes the time for Tenant, as a part 
of Tenant's Work, to install in the Premises Tenant's freestanding work 
stations, fixtures, furniture, equipment and telecommunication and computer 
cabling systems, and also includes the time for Tenant to move into the 
Premises.

         (c) DELAY OF COMMENCEMENT DATE. Notwithstanding anything to the 
contrary contained in the Lease or this Agreement, the date stated in Item 8 
of the Basic Lease Provisions for commencement of the Lease term (i.e., March 1,
1997) shall be deferred (i.e., pushed later in time) by a number of days 
equal to the number of days of delay in Substantial Completion (as defined 
below) of Tenant's Work that is caused by any Landlord Delay, as defined 
below.

         (d) CERTAIN DEFINITIONS. The following terms shall have the following
meanings:

             (i) The term "Landlord Delay" as used in the Lease or this 
Agreement shall mean any delay in the completion of Tenant's Work which is 
due to any act or omission of Landlord (wrongful, negligent or otherwise), 
its agents or contractors (including acts or omissions while acting as agent

                                                            J.E.S.        CS
                                                            H.T.S.

or contractor for Tenant). The term Landlord Delay shall include, but shall 
not be limited to any delay in the giving of authorizations or approvals by 
Landlord beyond the time periods therefor set forth herein.

             (ii) The term "Substantial Completion" shall mean: (A) Tenant 
has sufficiently completed all the work required to be performed by Tenant in 
accordance with this Agreement (except for minor punch list items which 
Tenant shall thereafter promptly complete), and (B) Tenant has obtained a

             (iii) The term "Lease" shall mean the entire lease document 
referred to in the first paragraph of this Agreement, including the printed 
lease form, the typed addenda paragraphs thereto and all exhibits thereto.

          If Tenant believes that any act or omission by Landlord or any 
employee or agent of Landlord is or will constitute a Landlord Delay 
resulting in a delay in completion of Tenant's Work, Tenant shall 
hand-deliver to Landlord a notice so stating and identifying in reasonable 
detail the act or omission alleged to constitute a Landlord Delay. If 
Landlord eliminates such alleged problem within forty-eight (48) hours after 
receipt of such notice, then such act or omission shall not be deemed to 
constitute a Landlord Delay. Nothing contained in clause (i) above shall be 
deemed or construed to constitute any permitted and timely disapproval by 
Landlord pursuant to this Agreement as a Landlord Delay or be deemed to 
interfere with or limit Landlord's rights to schedule construction activities 
at the Project for other tenants.

     3.   DESIGN OF TENANT'S WORK. Tenant shall arrange for design of 
Tenant's Work in accordance with the following:

          (a) SELECTION OF DESIGNER AND ENGINEER. In connection with the design 
of Tenant's Work, Tenant shall select an architect or designer ("Designer") 
and shall use an engineer designated by Landlord ("Engineer") who will 
perform the work required of it hereunder at competitive rates. The Designer 
and the Engineer shall each be familiar with all applicable Laws and Building 
Requirements to the extent such Building Requirements are provided to Tenant 
within the time specified in Paragraph 3(b) below. The Designer shall be 
selected by Tenant subject to Landlord's consent, which consent shall not be 
unreasonably withheld so long as each person or firm has all required state 
and local licenses and reasonable experience with projects of the size and 
scope of Tenant's Work. Such required approval shall be deemed given unless 
Landlord shall disapprove such person or firm by written notice to Tenant 
given within five (5) business days after Landlord's receipt of written 
notice from Tenant to Landlord identifying such person of firm and 
accompanied by a written statement as to the experience or such person or 
firm. This procedure shall be repeated until the Designer is finally 
approved, or deemed approved by Landlord.

          (b) BASE BUILDING PLANS. Landlord shall deliver to Tenant (i) 
instructions and Building plans and specifications (the "Base Building 
Plans") covering the Premises and such other portions of the Building as 
necessary for Tenant to design and construct Tenant's Work pursuant to this 
Agreement and (ii) the Building Requirements.

          (c) PREPARATION AND APPROVAL OF SPACE PLAN. Tenant shall submit to the
Designer all additional information including occupancy requirements for
the Premises ("Information") necessary to enable the Designer to prepare a
space plan showing all demising walls, corridors, entrances, exits, doors,
interior partitions, and the locations of all offices, conference rooms,
computer rooms, the reception area, file room and other support areas (the
"Space Plan") and the Working Drawings. The Designer shall incorporate
into the Working Drawings those items described in Exhibit "B" to the
Lease which Tenant is required to utilize in the construction of Tenant's
Work.

          Tenant shall cause the Designer to submit to Landlord the Space 
Plan for Landlord's review and approval. Landlord's approval of such 
Space Plan shall not be unreasonably withheld or delayed by Landlord, and 
shall be deemed given unless Landlord shall disapprove the same by written 
notice to Tenant within five (5) business days after Landlord's receipt of 
the same. Landlord's disapproval shall be based only upon reasonable and 
material reasons (which are defined to be (i) adverse effect on the 
structural integrity of the Building; (ii) possible damage to the Building 
Systems; (iii) non-compliance with applicable codes and other Laws; (iv) 
adverse effect on the exterior appearance of the Building; or (v) 
incompatibility with the Project including its design standards and standard 
materials (each, a "Design Problem")) and upon disapproval Landlord shall 
return the revised Space Plan to Tenant. In such event, Landlord shall 
require, and Tenant shall make, the changes necessary in order to correct the 
Design Problems and shall return the revised Space Plan to Landlord, which 
Landlord shall approve or disapprove within five (5) business days after 
Landlord receives the revised Space Plan. This procedure shall be repeated 
until the Space Plan is finally approved by Landlord and written approval has 
been delivered to and received by Tenant. The Space Plan as finally approved 
pursuant to this Paragraph 3(c) is herein referred to as the "Approved Space 
Plan."

below, such Working Drawings must incorporate the items required by Landlord 
for use in the Building, as set forth in Exhibit "B" attached to the Lease. 
The Working Drawings may be submitted in one or more stages and at one or 
more times.

          Landlord's approval of such Working Drawings shall not be 
unreasonably withheld or delayed by Landlord so long as the same are 
consistent with the Approved Space Plan, and shall be deemed given unless 
Landlord shall disapprove the same by written notice to Tenant given within 
five (5) business days after Landlord's receipt of a complete set of the 
Working Drawings. Landlord's disapproval shall be based only upon Design 
Problems(s) disclosed by such Working Drawings. If Landlord disapproves such 
Working Drawings in the manner and within the time provided in this Paragraph 
3(d), Landlord's notice of disapproval shall designate the specific changes 
reasonably required to be made to the Working Drawings in order to correct 
any Design Problem. Tenant shall make the changes necessary in order to 
correct any such Design Problem and shall return the revised Working Drawings 
to Landlord, which Landlord shall approve or disapprove within five (5) 
business days after Landlord receives the revised Working Drawings. This 
procedure shall be repeated until all of the Working Drawings are finally 
approved by Landlord and written approval has been delivered to and received 
by Tenant. The Working Drawings as finally approved pursuant to this 
Paragraph 3(d) are herein referred to as the "Approved Working Drawings."

          (e) PREPARATION AND APPROVAL OF ENGINEERING DRAWINGS. After the 
Working Drawings are finally approved by Landlord, Tenant shall submit to 
Landlord for Landlord's review and approval engineering drawings prepared by 
the Engineer, showing complete mechanical, electrical, plumbing, HVAC, 
telecommunication, and computer cabling plans ("Engineering Drawings"). The 
Engineering Drawings may be submitted in one or more stages and at one or 
more times.

          Landlord shall approve the Engineering Drawings within five (5) 
business days after receipt of a complete set of the same or designate by 
notice given within such time period to Tenant the specific changes 
reasonably required to be made to the Engineering Drawings in order to 
correct any Design Problem, and shall return the Engineering Drawings to 
Tenant. Tenant shall make the minimum changes necessary in order to correct 
any such Design Problem and shall return the revised Engineering Drawings to 
Landlord, which Landlord shall approve or disapprove within five (5) business 
days after Landlord receives the revised Engineering Drawings. This procedure 
shall be repeated until the Engineering Drawings are finally approved by 
Landlord and written approval has been delivered to and received by Tenant. 
The Engineering Drawings as finally approved pursuant to this Paragraph 3(e) 
are herein referred to as the "Approved Engineering Drawings."

          (f) INTEGRATION OF APPROVED WORKING DRAWINGS AND APPROVED 
ENGINEERING DRAWINGS INTO FINAL PLANS. Promptly after Landlord has approved 
the Approved Engineering Drawings, Tenant shall cause the Designer to 
integrate the Approved Working Drawings with the Approved Engineering 
Drawings (collectively, "Final Plans") and deliver the Final Plans to 
Landlord. Landlord shall approve the Final Plans within three (3) business 
days after receipt of a complete set of the same or designate by notice given 
within such time period to Tenant the specific changes reasonably required to 
be made to the Final Plans in order to correct any Design Problems and shall 
return the Final Plans to Tenant. Tenant shall make the minimum changes 
necessary in order to correct any such Design Problem and shall return the 
revised Final Plan to Landlord, which Landlord shall approve or disapprove 
within three (3) business days after Landlord receives the revised Final 
Plans. This procedure shall be repeated until the Final Plans are finally 
approved by Landlord and written approval has been delivered to and received 
by Tenant. The Final Plans as finally approved pursuant to this Paragraph 
3(f) are herein referred to as the "Approved Final Plans."

          (g) GOVERNMENTAL APPROVALS. Promptly following approval of the 
Approved Final Plans, Tenant shall apply for and obtain all governmental 
approvals and permits required for Tenant to commence Tenants, Work. 
Similarly, as and when required, Tenant shall obtain all additional 
governmental permits and approvals necessary to continuation and completion 
of Tenant's Work. All applications and other steps necessary to obtain such 
approvals and permits shall be the sole responsibility of Tenant. However, 
Landlord shall cooperate as reasonably requested from time to time without 
requirement that Landlord incur any out of pocket costs or assume any 
liabilities as a part of such cooperation.

      4.  CONTRACTOR, REVIEW OF PLANS AND CONSTRUCTION OF TENANT'S WORK.

          (a) SELECTION OF CONTRACTOR. Tenant shall select a contractor

                              RULES AND REGULATIONS

     1. The sidewalks, entrances, lobby, passages, courts, elevators,
vestibules, stairways, corridors and halls of the Building and Project
shall not be obstructed or used for any purpose other than ingress and
egress. The halls, passages, entrances, lobby, elevators, stairways,
balconies and roof are not for the use of the general public, and Landlord
shall in all cases retain the right to control and prevent access thereto
by all persons whose presence, in the judgment of Landlord, shall be
prejudicial to the safety, character, reputation and interests of the
Project and its tenants, provided that nothing herein contained shall be
construed to prevent such access to persons with whom Tenant normally deals
only for the purpose of conducting its business on the Premises (such as
clients, customers, office suppliers and equipment vendors, and the like)
unless such persons are engaged in illegal activities in the Project.
Neither Tenant nor any employee of Tenant shall go upon the roof of the
Building without the prior written consent of Landlord.

     2. No awnings or other projections shall be attached to the outside 
walls of the Building. No curtains, blinds, shades or screens shall be 
attached to or hung in, or used in connection with, any window or door of the

hung in offices or spaces along the perimeter of the Building must be 
fluorescent, of a quality, type, design and bulb color approved by Landlord. 
Neither the interior nor the exterior of any windows shall be coated or 
otherwise sunscreened without the written consent of Landlord. No hanging 
planters, television sets or other objects shall be attached to or suspended 
from the ceiling by any tenant without the prior written consent of Landlord.

     3. Except as provided in Paragraph 30 of the Lease, no sign,
advertisement, notice or handbill shall be exhibited, distributed, painted
or affixed by Tenant on, about or from any part of the Premises, the
Building or the Project without the prior written consent of Landlord. If
Landlord shall have given such consent at the time, whether before or
after the execution of the Lease, such consent shall in no way operate as a
waiver or release of any of the provisions hereof or of the Lease, and
shall be deemed to relate only to the particular sign, advertisement or
notice so consented to by Landlord and shall not be construed as dispensing
with the necessity of obtaining the specific written consent of Landlord
with respect to each and every such sign, advertisement or notice other
than the particular sign, advertisement or notice, as the case may be, so
consented to Landlord. In the event of the violation of the foregoing by
Tenant, Landlord may remove or stop same without any liability, and may
charge the expense incurred in such removal or stoppage to Tenant. Interior
signs on doors and directory tablets shall be inscribed, painted or
affixed for Tenant by Landlord at Tenant's expense, and shall be of a size,
color, material and style acceptable to Landlord. The directory tablet will
be provided exclusively for the display of the names and locations of
tenants only and Landlord reserves the right to exclude any other names
therefrom. Nothing may be placed on the exterior of corridor walls or
corridor doors other than Landlord's standard lettering.

     4. The sashes, sash doors, skylights, windows and doors that reflect or 
admit light and air into hills, passageways or other public places in the 
Building shall not be covered or obstructed by Tenant, nor shall any bottles, 
parcels or other articles be placed on the windowsills. Tenant shall see that 
the windows, transoms and doors of the Premises are closed and securely 
locked before leaving the Building and must observe strict care not to leave 
windows open when it rains. Tenant shall exercise extraordinary care and 
caution that all water faucets or water apparatus are entirely shut off 
before Tenant or Tenant's employees leave the Building, and that all 
electricity, gas or air shall likewise be carefully shut off, so as to 
prevent waste or damage. Tenant shall cooperate with Landlord in obtaining 
maximum effectiveness or the cooling system by closing blinds when the sun's 
rays fall directly on the windows of the Premises. Tenant shall not tamper 
with or change the setting of any thermostats or temperature control valves 
installed by Landlord. All lights in Tenant's premises shall be turned off at 
night and on weekends and holidays when such premises are not in use.

     5. The toilet rooms, water and wash closets and other plumbing fixtures 
shall not be used for any purpose other than those for which they were 
constructed, and no sweepings, rubbish, rags, or other substances shall be 
thrown therein. All damages resulting from any misuse of the fixtures shall 
be borne by the tenant who, or whose subtenants, assignees or any of whose 
servants, employees, agents, visitors or licensees shall have caused the same.

     6. Tenant shall not mark, paint, drill into, or in any way deface any 
part of the Premises, the Building or the Project. No boring, cutting or

circuit. Tenant shall not cause or permit any unusual or objectionable

the Premises. Tenant shall not occupy or permit any portion of the Premises 
to be occupied as an office for a public stenographer or typist, or for the 
manufacture or sale of liquor, narcotics, or tobacco (including a cigarette

the express prior written consent of Landlord. Tenant shall not engage or pay

The Premises shall not be used for lodging or sleeping or for any immoral or 
illegal purposes.

noises or disturb or interfere with occupants of this or neighboring 
buildings or premises or those having business with them, whether by the use 
of any musical instrument, radio, phonograph, unusual noise, or in any other 
way. Tenant shall not throw anything out of doors, windows or skylights or 
down the passageways.

    10. No Tenant, or subtenant or assignee of Tenant, if any, nor any of 
their servants, employees, agents, visitors or licensees shall at any time 
bring or keep upon any premises any inflammable, combustible or explosive 
fluid, chemical or substance.

    11. No additional locks or bolts of any kind shall be placed upon any of 
the doors or windows by Tenant, nor shall any changes be made in existing 
locks or the mechanisms thereof. Tenant must, upon the termination of its 
tenancy, restore to Landlord all keys to stores, offices, and toilet rooms, 
either furnished to or otherwise procured by Tenant, and in the event of the 
loss of keys so furnished, Tenant shall pay to Landlord the cost of replacing 
the same or of changing the lock or locks opened by any lost key if Landlord 
shall deem it necessary to make such changes.

    12. All removals, and the carrying in or out of any safes, freight, 
furniture, and bulky matter of any description must take place during the 
hours which Landlord shall determine from time to time, and shall not be done 
without the express written consent of Landlord. The moving of safes and 
other fixtures and bulky matter of any kind must be done upon previous notice 
to the manager of the Building and under such person's supervision, and the 
persons employed by Tenant for such work must be acceptable to Landlord. 
Landlord reserves the right to inspect all safes, freight and other bulky 
articles to be brought into the Building and to exclude from the Building all 
safes, freight and other bulky articles which violated any of these Rules and 
Regulations or the Lease. Landlord reserves the right to prescribe the weight 
and position of all safes, which must be placed upon supports approved by 
Landlord to distribute the weight. No tenant shall place a load upon any 
floor which exceeds the load per square foot which such floor was designed to 
carry and which is allowed by law. Tenant shall be responsible for all 
damages occasioned by its movement into or out of the Building of any item 
described in this paragraph. All safes, freight and other bulky articles 
shall be taken into and removed from the Premises solely on the freight 
elevator of the Building and the freight loading and unloading areas adjacent 
thereto.

maintenance or other like services from any person or persons not approved by 
Landlord and only at hours and under regulations fixed by Landlord.

     14. Landlord shall have the right to prohibit any advertising by Tenant

or the Project or the desirability of the Project as an office location.

such advertising.

personnel and who do not present a pass to the Building approved by Landlord. 
Landlord will furnish passes to persons for whom Tenant requests the same in 
writing. Tenant shall be responsible for all persons for whom it requests 
passes and shall be liable to Landlord for all acts of such persons. Landlord 
shall in no case be liable for damages for any error with regard to the 
admission to or exclusion from the Building of any person. In case of an 
invasion, mob riot, public excitement or other circumstances rendering such 
action advisable in Landlord's opinion, Landlord reserves the right without 
any abatement of rent to require all persons to vacate the Building and to 
prevent access to the Building during the continuance of the same for the 
safety of Tenant and the protection of the Building and the property in the 
Building, and no such action by Landlord shall entitle Tenant to any 
abatement of rent. Tenant shall observe all security regulations issued by 
Landlord and shall comply with all instructions and/or directions of Building 
personnel.

directions from Landlord.

     26. The term "personal goods or services vendors" as used herein means
persons who periodically enter the Building for the purpose of selling
goods or services to Tenant, other than goods or services which are used
by Tenant only for the purpose of conducting its business on the Premises.
"Personal goods or services" include, but are not limited to, food items,
drinking water and other beverages, food, barbering services and
shoeshining services. Landlord reserves the right to prohibit personal
goods and services vendors from access to the Building except upon such
reasonable terms and conditions, including but not limited to the payment
of a reasonable fee and provision for insurance coverage, as are related to
the safety, care and cleanliness of the Building, the preservation of good
order therein, and the relief of any financial or other burden on Landlord
occasioned by the presence of such vendors or the sale by them of personal
goods or services to Tenant or its employees. If necessary for the
accomplishment of these purposes, Landlord may exclude a particular vendor
entirely or limit the number of vendors who may be present at any one time
in the Building.

     27. It shall be the responsibility of each tenant to provide its 
employees with keys to its premises. Landlord will under no circumstances

     28. Smoking or carrying a lighted cigar, cigarette or pipe anywhere in 
the interior of the Building is prohibited. Smoking is also prohibited in the 
common areas of the Project, except for those specific areas designated in 
writing by Landlord. The location of such areas shall be determined by 
Landlord in its sole discretion. Landlord hereby reserves the right from time 
to time to designate substitute smoking areas within the common areas in its 
sole discretion. 

     29. No waiver of any rule or regulation by Landlord shall be effective 
unless expressed in writing and signed by Landlord. Landlord may waive any 
one or more of these rules for the benefit of a particular tenant or tenants, 
but no such waiver by Landlord shall be construed as a waiver of such rules 
in favor of any other tenant or tenants, nor prevent Landlord from thereafter 
enforcing any such rules against any or all tenants of the Building.

                                PARKING AGREEMENT    

   Subject to the parking entitlements, if any, set forth in the lease to 
which this Parking Agreement is attached (the "Lease") and subject to 
availability, and further subject to compliance with the following Rules and 
Regulations, so long as the Lease remains in effect and subject to 
availability, Tenant or employees of Tenant shall be entitled to purchase up 
to thirty-four (34) parking contracts for spaces in the Project Parking 
Structure in an amount as determined by Landlord. The Project Parking 
Structure is depicted on Exhibit "A-3." All or part of any unreserved or 
unassigned parking spaces may be assigned to, made available to, or reserved 
by Landlord for other tenants or users of the Project, if Landlord determines 
that such action is necessary for orderly and efficient parking. Tenant shall 
pay a charge for the use of such parking contracts at the monthly rental 
rates of $100.00 for reserved parking contracts and $60.00 per month for 
unreserved parking contracts. Tenant may validate visitor parking by such 
method(s) as Landlord or Landlord's parking operator may approve, at the 
validation rate from time to time generally applicable to visitor parking. 
Landlord expressly reserves the right to redesignate or modify any portion of 
the Project Parking Structure for other uses or to any extent.

   The parking spaces hereunder shall be provided on an unreserved 
"first-come, first-served" basis. Tenant acknowledges that Landlord has or 
may arrange for the Project Parking Structure to be operated by an 
independent contractor, not affiliated with Landlord. In such event, Tenant 
acknowledges that Landlord shall have no liability for claims arising through 
acts or omissions of such independent contractor. Landlord shall have no 
liability whatsoever for any damage to property or any other items located in 
the Project Parking Structure, nor for any personal injuries or death arising 
out of any matter relating to the Project Parking Structure, and in all 
events, Tenant agrees to look first to its insurance carrier and to require 
that Tenant's employees look to their respective insurance carriers for 
payment of any losses sustained in connection with any use of the Project 
Parking Structure. Tenant hereby waives on behalf of its insurance carriers 
all rights of subrogation against Landlord or Landlord's agents.

   All persons utilizing the Project Parking Structure shall comply with this 
Parking Agreement, including any parker identification system(s) established 
by Landlord's parking operator. The following Rules and Regulations are in 
effect until Landlord notifies Tenant of any change. Landlord reserves the 
right to modify and/or adopt such other reasonable and non-discriminatory 
rules and regulations for the Project Parking Structure as it deems 
necessary. Landlord may refuse to permit any person who violates this Parking 
Agreement to park in the Project Parking Structure. Any violation of this 
Parking Agreement shall subject the violator's car to removal from the 
Project Parking Structure at the violator's expense. Upon the termination of 
any person's parking privileges under this Parking Agreement, Tenant shall 
cause all parker identification devices supplied to such person by Landlord 
to be returned to Landlord.

                              RULES AND REGULATIONS

by Landlord shall remain the property of Landlord. Such parking
identification devices must be displayed as requested and may not be

mutilated in any manner. The serial number of the parking identification
device may not be obliterated. Devices are not transferable and any device
in the possession of an unauthorized holder will be void. There will be a
replacement charge payable by Tenant or a person designated by Tenant equal
to the amount posted from time to time by Landlord for loss of any parking
sticker.

   7. The monthly charge for rental of a parking space shall be payable in
advance on or prior to the first day of each month. Failure to do so will
automatically cancel parking privileges and a late charge at the rate
charged by Landlord from time to time shall be due. No deductions or
allowances from the monthly charge will be made for days a parker does not
use the parking space rented by him or her.

   8. Landlord's parking operator and its employees are not authorized to make
or allow any exceptions to these Rules and Regulations.

   9. Every parker is required to park and lock his or her own car. All
responsibility for damage to cars or persons is assumed by the parker.

   10. Loss or theft of parking identification devices from automobiles shall
be reported to the Landlord's parking operator immediately, and a lost or
stolen report must be filed by the customer at that time. Any parking
identification device reported lost or stolen found on any unauthorized car
will be confiscated and the illegal holder will be subject to prosecution.
Lost or stolen devices found by a parker must be reported to Landlord's
parking operator immediately to avoid confusion.

   11. No more than one vehicle may be parked in any one parking space.
Washing, waxing, cleaning or servicing of any vehicle by a parker and/or
his or her agents is prohibited.

   12. Landlord and Landlord's parking operator reserve the right to refuse
the sale of monthly stickers or other parking identification devices to
any person who willfully refuses to comply with these Rules and Regulations
and all applicable city, state or federal ordinances, laws or agreements.

   13. Tenant shall acquaint all persons to whom Tenant assigns parking spaces
with these Rules and Regulations.

   14. Notwithstanding anything in this Parking Agreement to the contrary,
persons who desire to rent parking spaces in the Project Parking Structure
shall be required to pay a $25.00 deposit for each magnetic parking card
issued to them by Landlord. Such deposit shall be paid at the time the
parking card is issued. Such deposit shall be forfeited if the parking
card is lost. Such deposit shall be returned, without interest, at the
time each such person ceases utilizing the parking space provided by
Landlord upon surrender of such person's parking card. Landlord reserves
the right to charge an amount in excess of the $25.00 deposit to replace
lost parking cards, if such increase becomes necessary in Landlord's
reasonable judgment to prevent creation of a so-called "black market" in
parking cards. Landlord shall post notices of any such increase(s).

   15. Handicapped and visitor stalls shall be used only by handicapped 
persons or visitors, as applicable.

   16. In the event that, from time to time, the Project Parking Structure is
renovated or replaced, in whole or in part, Landlord shall have the right
to reasonably relocate Tenant's parking privileges to other parking
facilities within the vicinity of the Project on a temporary basis.

   17. Parking on any driveways, access roads, turn-arounds and curbsides 
located throughout the Project and the common areas is strictly prohibited. 
Landlord shall have the right to cause any vehicles which are parked or 
otherwise left unattended in such areas to be towed away at the vehicle 
owner's expense.

                           SECOND AMENDMENT TO LEASE


     THIS SECOND AMENDMENT TO LEASE (the "Amendment") is made and entered 
into as of the 18th day of February, 1999 by and between FIFTH STREET 
PROPERTIES, LLC, a Delaware limited liability company ("Landlord"), and IMGIS,
Inc. (dba AdForce, Inc.), a California corporation ("Tenant"), with respect 
to the following:

                                    RECITALS

      A.  Landlord's predecessor in interest and Tenant entered into a 
certain written lease dated December 20, 1996 (the "Original Lease"), as 
amended by that certain First Amendment to Lease dated February 18, 1998 (the 
"First Amendment"). The Original Lease and the First Amendment are 
collectively referred to as the "Lease". The Lease covers certain premises 
commonly known as Suites 400 and 475 (the "Premises"), 611 Anton Boulevard 
(the "Building"), Costa Mesa, California.

      B.  Pursuant to the terms hereof, Landlord and Tenant desire to extend 
the term of the Original Lease and to expand the Premises to include Suites 
450 and 550 (hereinafter individually referred to by suite number and 
collectively referred to as the "Additional Premises"), which Additional 
Premises consists of 5,505 square feet of Rentable Area in the aggregate.
Suite 450 consists of 1,212 square feet of Rentable Area and Suite 550
consists of 4,293 square feet of Rentable Area. The Additional Premises shall 
be approximately as depicted on Exhibit "A" attached to this Amendment.

      D.  Landlord and Tenant desire to enter into this Amendment to set 
forth the terms upon which the Additional Premises shall be added to the 
Premises. In addition, Landlord and Tenant desire to set forth certain 
changes in the terms of the Lease upon which Tenant shall hold and occupy the 
Premises and the Additional Premises.

                                   AGREEMENT

      IN CONSIDERATION OF the foregoing recitals and the mutual promises and 
covenants contained herein, Landlord and Tenant agree as follows:

      1.    EXPANSION OF PREMISES/TERM.

          (a)  Landlord hereby leases to Tenant and Tenant hereby leases from 
Landlord the Additional Premises, subject to all of the terms and conditions 
of this Amendment and of the Original Lease. The term of the Lease with 
respect to Suite 450 shall commence on March 1, 1999 (the "Suite 450 
Effective Date"). The term of the Lease with respect to Suite 550 shall have 
a target commencement date of April 15, 1999 but shall have an actual 
commencement date, subject to the provisions of Exhibit "B", on the earlier of 
(i) Substantial Completion of Landlord's work pursuant to Exhibit "B", (ii) 
the date upon which Landlord would have completed Landlord's work but for 
delays in construction caused by Tenant or (iii) upon such date as Tenant 
takes possession of and commences use of Suite 550 for the conduct of its 
normal business operations, (the "Suite 550 Effective Date"). Within thirty 
(30) days following the date of commencement of the term for Suite 550, 
Landlord and Tenant shall execute a supplemental agreement, in letter form, 
setting forth the Suite 550 Effective Date. Notwithstanding the foregoing, 
failure of Tenant to execute such supplemental agreement shall

                                      -1-


<PAGE>


not affect Landlord's determination of the Suite 550 Effective Date in 
accordance with this Amendment.

          (b)  If Tenant delays Landlord in the construction of Suite 550 
pursuant to Exhibit "B", Landlord shall tender Suite 550 to Tenant upon 
written notice stating that, except for such delays caused by Tenant, Suite 
550 will be or would have been ready for occupancy on the date specified in 
such notice. The date set forth in such notice shall be the Suite 550 
Effective Date, regardless of whether Tenant takes possession of Suite 550 on 
such date. 

          (c)  The target commencement date stated in Paragraph 1(a) above, 
is an estimated date by which Landlord's work will be completed as provided 
in Exhibit "B". If Landlord is unable to tender possession of Suite 550 on 
that date, this Amendment shall not be void or voidable, nor shall Landlord 
be liable for any loss or damage resulting therefrom, except to the extent 
caused by Landlord's gross negligence or willful misconduct. In the event 
that Landlord delivers Suite 550 after April 15, 1999, the term of the Lease 
as to all space shall be extended one (1) day for each day of such delay in 
delivery such that the term for all space is a full five (5) years following 
the Suite 550 Effective Date.

          (d)  Landlord's sole construction obligation under this Amendment 
is set forth in Exhibit "B" and Landlord shall have no other obligation to 
otherwise modify or prepare any of the Additional Premises for occupancy by 
Tenant. Landlord and Tenant acknowledge that Landlord shall use diligent 
efforts to commence and complete such construction of Suite 550 as promptly 
as practicable.

          (e)  The term of the Lease shall be extended for forty-five (45) 
days so as to expire on April 14, 2004. The term as to the Additional
Premises shall be co-terminus with the Premises and shall expire on April 14, 
2004. There shall be no option to further extend the term of the Lease.

          (f)  Tenant's security deposit shall be increased by $17,051.28 
payable concurrently with Tenant's execution and delivery of this Amendment 
to Landlord.

      2.  RENT.  Rent shall be as follows:

          (a)  From the Suite 450 Effective Date until termination, Basic 
Annual Rent for Suite 450 shall be at the rate of $25.00 per square foot of 
Rentable Area (approximately $2.08 per square foot per month). Therefore, 
Basic Annual Rent for Suite 450 during such period shall be $30,300.00 
($2,525.00 per month).

          (b)  From the Suite 550 Effective Date until termination, Basic 
Annual Rent for Suite 550 shall be at the rate of $25.00 per square foot of 
Rentable Area (approximately $2.08 per square foot per month). Therefore, 
Basic Annual Rent for Suite 550 during such period shall be $107,325.00 
($8,943.75 per month).

          (c)  In addition, Tenant shall continue to pay all Additional Rent 
provided for in the Original Lease. Pursuant to the provision of Exhibit 
"A-4" of the Original Lease, Landlord has caused the Building and the Project 
to be remeasured utilizing Stevenson's Systems, Inc., an independent 
contractor ("Stevenson"). Stevenson has determined the building to be 299,263 
square feet of Rentable Area and the Project to be 720,633 square feet of 
Rentable Area. Therefore, commencing on January 1, 1999, to and until the 
Effective Date, Additional Rent shall be based upon the Rentable Area of 
Premises, or 12,857 square feet and utilizing the Building Expense 
Percentage of 4.5223% and Project Expense Percentage of 1.8780%. From the 
Suite 450 Effective Date until the


                                      -2-

<PAGE>

Suite 550 Effective Date, Additional Rent shall be based upon the Rentable 
Area of the Premises and Suite 450, or 14,069 square feet and utilizing the 
Building Expense Percentage of 4.9486% and the Project Expense Percentage of 
2.0551%. From the Suite 550 Effective Date until expiration of the term, 
Additional Rent shall be based upon the Rentable Area of the Premises and the 
Additional Premises or 18,362 square feet and utilizing the Building Expense 
Percentage of 6.4587% and the Project Expense Percentage of 2.6821%.

          (d)  For the period following the original expiration date of the 
Original Lease (February 28, 2004), Basic Annual Rent for the original 
Premises shall be increased to the same rate as then applicable for the 
Additional Premises.

      3.  IMPROVEMENTS TO ADDITIONAL PREMISES.

          (a)  Landlord shall deliver Suite 450 in its then existing "AS-IS" 
condition on or about February 1, 1999. Landlord shall have no obligation 
with respect to any improvement or modification of such space and Tenant 
shall be responsible for any such modifications which shall be undertaken in 
full compliance with the terms and conditions of the Original Lease.

          (b)  Prior to delivery of Suite 550 to Tenant, Landlord shall 
improve the space pursuant to the provisions of Exhibit "B" attached hereto 
and made a part hereof.

      4.  TERMS AND CONDITIONS FOR THE ADDITIONAL PREMISES. From and after 
the Suite 450 Effective Date and the Suite 550 Effective Date, respectively, 
Tenant shall hold and occupy Suite 450 and Suite 550 upon all of the terms 
and conditions of the Original Lease as amended by this Amendment and, in the 
event of any inconsistency between the Original Lease, the First Amendment 
and this Amendment, the provisions of this Amendment shall control.

      5.  MODIFICATIONS TO ORIGINAL LEASE.

          (a)  Notwithstanding the provisions of Paragraph 6(c) of the 
Original Lease to the contrary, Tenant may make cosmetic alterations to the 
Premises, as expanded, without securing Landlord's prior written consent 
provided: (i) such modifications shall cost not more than $10,000 during any 
calendar year of the term; (ii) such modifications are in the nature of 
normal and usual office improvements; and (iii) such modifications do not 
affect any of the mechanical electrical or plumbing systems of the Building and 
are not visible from the exterior of the Building. Further, in cases where 
Landlord's consent is required, Landlord shall advise Tenant at the time of 
such consent whether or not Landlord will require removal of such improvement 
at expiration of the term.

          (b)  Notwithstanding anything in Paragraph 14 of the Original Lease 
to the contrary, in the event that Tenant is notified by Landlord of the fact 
that within twelve (12) months of any damage or destruction of the Premises, 
as expanded, and/or the Building or any part thereof so as to preclude 
Tenant's use of the Premises, Tenant cannot be given reasonable use of, and 
access to, a fully repaired and restored Premises and Building (except for 
minor "punch-list" items which will be repaired promptly thereafter), and the 
utilities and services pertaining to the Building and the Premises, as 
expanded, all suitable for the efficient conduct of Tenant's business 
therefrom, then Tenant may elect to exercise a right to terminate the Lease 
upon ten (10) days written notice sent to Landlord at any time within a 
period of thirty (30) days following Tenant's receipt of Landlord's notice as 
specified above. If Tenant gives timely notice of termination as provided 
above, this Lease shall terminate thirty (30) days after Landlord's receipt of 
Tenant's notice of termination.

          (c)  Notwithstanding the provisions of Paragraph 16(d) of the 
Original Lease, any profits realized by Tenant in connection with such 
transaction shall be handled in accordance with the provisions hereof. As a 
condition to Landlord's consent to any assignment or sublease, Landlord and 
Tenant shall equally share any quote "profits" which may result from such 
assignment or sublease. For purposes herein, "profits" shall mean the "rent" 
or "consideration" (as such terms are defined in Paragraph 16(d) of the 
Original Lease) received from the assignee or subleasee during the sublease 
term or on account of the assignment, less: (i) the gross revenue paid to 
Landlord by Tenant during the period of the sublease term or during the 
assignment; (ii) any brokers commissions paid in connection with such 
transaction.

          (d)  Notwithstanding the provisions of Paragraph 26(a)(ii) of the 
Original Lease to the contrary, the Premises, as expanded, shall be 
considered "abandoned" only if Tenant is absent from such Premises, as 
expanded, for five (5) days or longer and Tenant is otherwise in default 
under the Lease.

          (e)  Notwithstanding the provisions of Paragraph 27 of the Original 
Lease to the contrary, as to the Additional Premises only, and only for the 
first sixty (60) days of any such holdover of all or any portion of the 
Additional Premises, the holdover rental rate shall be one hundred fifty 
percent (150%) of the Basic Annual Rent and Additional Rent than in effect. 
Thereafter, the holdover rates shall be as provided in Paragraph 27 of the 
Original Lease.

          (f)  With respect to Paragraph 44 of the Original Lease, it is 
understood and agreed that Tenant may disclose the Lease to the United States 
Securities and Exchange Commission and as may thereafter be required in 
connection with Tenant offering its stock for sale to the public.

      6.  BROKERS.  Except for Landlord's agent South Coast Plaza, each of 
Landlord and Tenant represents and warrants to the other that it has employed 
no broker, finder or real estate agent in connection with this Amendment and 
the transactions provided for herein, and that there is no broker, finder or 
real estate agent who is entitled to a fee or commission from or through such 
indemnifying party in connection with this Amendment or the transactions 
provided for herein. Each of Landlord and Tenant agrees to indemnify, defend 
and hold the other harmless from and against all claims for a fee or 
commission by any broker, finder or agent claiming through such indemnifying 
party with respect to this Amendment or the transactions provided for herein. 
Payment shall not be a condition precedent to recovery upon the foregoing 
indemnification provision. The foregoing indemnification provision shall be 
deemed to include a covenant by each indemnifying party to defend the 
indemnified party against claims covered by such indemnification with legal 
counsel reasonably satisfactory to the indemnified party.

      7.  COUNTERPARTS.  This Amendment may be executed in two or more 
counterparts, each of which shall be deemed an original, but all of which

capital letters and not defined herein shall have the meanings given to such 
terms in the Original Lease or First Amendment, as applicable.

      9.  LEASE IN EFFECT.  Landlord and Tenant acknowledge and agree that 
the Original Lease, as amended by the First Amendment and this Amendment, is 
in full force and effect in accordance with its terms.

                                  WORK LETTER

     In connection with the Amendment to which this Work Letter is attached 
(the "Amendment"), Landlord and Tenant hereby agree to the terms and 
conditions set forth in this Work Letter relating to the construction of the 
tenant improvements in Suite 550 (the "Tenant Improvements"). This Work 
Letter is essentially organized chronologically and addresses the issues of 
the construction of Suite 550, in sequence, as such issues will arise during 
the actual construction of Suite 550. All capitalized terms used but not 
defined herein shall have the meanings given such terms in the Lease.


                                   SECTION 1.

                         CONSTRUCTION DRAWINGS FOR SUITE 550

    Landlord and Tenant have mutually approved (i) a space plan for Suite 550 
(the "Space Plan") and (ii) the notes and specifications set forth in such 
space plan (collectively, the "Approved Space Plan"). Within three (3) days 
of the date of execution of this Amendment by Tenant, Tenant shall cooperate 
in good faith with Landlord's architects and engineers to supply such 
information necessary to allow the Landlord's architects and engineers to 
complete the architectural and engineering drawings for Suite 550, and the 
final architectural working drawings in a form which is in compliance with 
ADA (including any special requirements as a result of Tenant's 
employer-employee obligations under ADA, and complete to allow subcontractors 
to bid on the work and to obtain all applicable permits and in a manner 
consistent with the Approved Space Plan (collectively, the "Approved Working 
Drawings"). Landlord shall construct, at Landlord's cost, the Tenant 
Improvements pursuant to the Approved Working Drawings, provided, however, in 
no event shall Landlord's obligation for the payment of Tenant Improvements 
exceed $90,550.00. In connection with the Tenant Improvements, it is 
understood and agreed that Landlord's obligation for the payment of costs, 
subject to the maximum, shall be limited to costs to design, engineer and 
construct Suite 550 including all professional service fees, labor and 
materials relative to the installation of permanent improvements in Suite 550 
including architectural fees and contractor fees. Tenant shall make no 
changes or modifications to the Approved Space Plan or to the Approved 
Working Drawings without the prior written consent of Landlord, which consent 
may be withheld in Landlord's reasonable discretion if such change or 
modification would delay, directly or indirectly, Substantial Completion (as 
such term is defined in Section 2, below) of construction of the Tenant 
Improvements, would be inconsistent with the Approved Space Plan or would 
increase the cost of designing or constructing the Tenant Improvements when 
compared to the cost incurred by Landlord in using the quality of the "Building 
Standard Items" described on Schedule "1" attached hereto to the extent 
depicted on the Approved Space Plan or is otherwise inconsistent with ADA. Any 
such increased cost or costs in excess of Landlord's maximum obligation, 
shall be paid by Tenant to Landlord within five (5) days after Landlord's 
written request for payment.


                                   SECTION 2.

                            SUBSTANTIAL COMPLETION

     The term "Substantial Completion" means that Landlord has completed the 
Tenant Improvements and other work that it is obligated to perform pursuant 
to this Work Letter, and that this work shall be deemed complete, 
notwithstanding the fact that minor details of construction, mechanical 
adjustments


<PAGE>


or decorations which do not materially interfere with Tenant's use of Suite 
550 remain to be performed (items normally referred to as "Punch-List 
Items"). Suite 550 shall be deemed to have achieved Substantial Completion 
even though Tenant's furniture, telephones, telexes, telecopiers, photocopy 
machines, computers and other business machines or equipment have not been 
installed, the purchase and installation of which shall be Tenant's sole 
responsibility.

     Tenant shall notify Landlord and Contractor within three (3) business 
days after Substantial Completion of Suite 550 and in any event prior to 
Tenant's occupancy of Suite 550, of any Punch-List Items which need to be 
completed or corrected, and Landlord shall cause such Punch-List Items to be 
completed or corrected within a reasonable time thereafter.


                                   SECTION 3.

                    CONTRACTOR'S WARRANTIES AND GUARANTIES

      Landlord will upon completion of the Tenant Improvements and after 
Tenant's acceptance of Suite 550 assign to Tenant all warranties and 
guaranties by the contractor who constructs the Tenant Improvements (the 
"Contractor") relating to the Tenant Improvements, and Tenant hereby waives 
all claims against Landlord relating to, or arising out of the construction 
of, the Tenant Improvements. Such warranties and guaranties of Contractor 
shall guarantee that the Tenant Improvements shall be free from defects in 
workmanship and materials for a period of not less than one (1) year from 
date of completion thereof, and Contractor shall be responsible for the 
replacement and repair, without additional charge, of the Tenant Improvements 
that shall become defective within one (1) year after Substantial Completion 
of Suite 550. The Contractor shall be selected by Landlord.


                                   SECTION 4.

                      COMPLETION OF THE TENANT IMPROVEMENTS:
                               COMMENCEMENT DATE

      Consistent with the provisions set forth in Paragraph 1 of the 
Amendment, if there shall be a delay or there are delays in the Substantial 
Completion of Suite 550 as a direct, indirect, partial, or total result of:

      (a)  Tenant's failure to timely approve any matter requiring Tenant's 
approval;

      (b)  A breach by Tenant of the terms of this Work Letter, this 
Amendment or the Original Lease;

      (c)  Tenant's request for changes in the Approved Space Plan or 
Approved Working Drawings;

      (d)  Tenant's requirement for materials, components, finishes or 
improvements which are not available in a commercially reasonable time given 
the anticipated date of Substantial Completion of Suite 550, as set forth in 
the Amendment, or which are different than Landlord's Building Standard Items;

      (e)  Any other acts or omissions of Tenant, or its agents, or employees;


                                       2


<PAGE>


then, notwithstanding anything to the contrary set forth in the Amendment or 
this Work Letter and regardless of the actual date of the Substantial 
Completion of Suite 550, the Suite 550 Effective Date shall be deemed to be 
the date the Suite 550 Effective Date would have occurred if no Tenant delay 
or delays, as set forth above, had occurred.


                                    SECTION 5.

                                   MISCELLANEOUS

      5.1  TENANT'S ENTRY INTO SUITE 550 PRIOR TO SUBSTANTIAL COMPLETION.  
Provided that Tenant and its agents do not interfere with Contractor's work 
in the Building and Suite 550, Contractor shall allow Tenant access to Suite 
550 prior to the Substantial Completion of Suite 550 (but if such access is 
to be prior to the issuance of a certificate of occupancy of the Building by 
the City of Costa Mesa, then such access shall be only as allowed by the City 
of Costa Mesa) for the purpose of Tenant installing overstandard equipment or 
fixtures (including Tenant's data and telephone equipment) in Suite 550. 
Prior to Tenant's entry into Suite 550 as permitted by the terms of this 
Section 5.1, Tenant shall submit a schedule to Landlord and Contractor, for 
their approval, which schedule shall detail the timing and purpose of 
Tenant's entry. Tenant shall hold Landlord harmless from and indemnify, 
protect and defend Landlord against any loss or damage to the Building or 
Suite 550 and against injury to any persons caused by Tenant's actions 
pursuant to this Section 5.1.

      5.2  FREIGHT ELEVATORS.  Landlord shall, consistent with its 
obligations to other tenants of the Building, and subject to the needs of 
Landlord with respect to any construction or alteration of the Base, Shell 
and Core of the Building, make the freight elevator reasonably available to 
Tenant in connection with initial decorating, furnishing and moving into 
Suite 550.

      5.3  TENANT'S REPRESENTATIVE.  Tenant has designated Nadine Franczyk as 
its sole representative with respect to the matters set forth in this Work 
Letter, who, until further notice to Landlord, shall have full authority and 
responsibility to act on behalf of the Tenant as required in this Work Letter.

      5.4  LANDLORD'S REPRESENTATIVE.  Landlord has designated Bob Goodwin as 
its sole representative with respect to the matters set forth in this Work

Landlord and Tenant, as their interests may appear, as well as the Contractor,

Landlord and Tenant. All insurance maintained by Tenant's agents shall 
preclude subrogation claims by the insurer against any one insured 
thereunder. Such insurance shall provide that it is primary insurance as 
respects the Landlord and that any other insurance maintained by Landlord is

indicated, all references herein to a "number of days" shall mean and refer 
to calendar days. In such instances where Tenant is required to approve or 
deliver an item, if no written notice of approval is given or the item is not 
delivered within the stated time period, at Landlord's sole option, at the 
end of such period the item shall automatically be deemed approved or 
delivered by Tenant and the next succeeding time period shall commence.

of this Work Letter shall be forgiven until such time as such default is cured
pursuant to the terms of the Lease.

ADFORCE-TM- SERVICE AGREEMENT                               24/7 Media Agreement
- --------------------------------------------------------------------------------

This Service Agreement ("Agreement") is entered into as of January 1, 1999 (the
"Effective Date") between 24/7 Media, Inc., a Delaware corporation with its
principal executive offices at 1250 Broadway, New York, New York 10001-3701
("24/7 Media"), and Imgis, Inc., d/b/a "AdForce," a California corporation with
offices at 10590 North Tantau Avenue, Cupertino, CA 95014 ("AdForce").

1.   ADFORCE SERVICE DEFINITION. The AdForce service is an Internet advertising
     administration system that will allow 24/7 Media to manage advertising
     across its network of multiple Web sites. As part of the AdForce service,
     AdForce will provide 24/7 Media the AdForce client application ("Client"),
     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.

4.   OWNERSHIP/LIMITATIONS ON USE.  Subject to the terms and conditions of this
     Agreement, 24/7 Media will have the right to use the Client in its offices
     solely for purposes of using the AdForce service.  AdForce shall at all
     times have sole and exclusive ownership of all right, title and interest in
     and to such Client and the AdForce service as a whole, any enhancements
     thereto and in any materials and data AdForce provides to 24/7 Media.
     Notwithstanding anything contained elsewhere in this Agreement, the parties
     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
     customers and is used for designing, scheduling or administering campaigns,
     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
     24/7 Media.  Accordingly, AdForce may not use such Campaign Data for any
     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
     it is free to enter into and perform this Agreement and, except for events
     beyond AdForce's control, including but not limited to Internet service
     disruptions or access outages and other events of force majeure, (a) the
     AdForce service will conform in all material respects to the functionality
     described in Sections 1 and 2; (b) AdForce either owns, has, or will
     otherwise acquire the right (and will, during the term hereof maintain such

     property rights of any third party.

     in any way by any date data, date setting, date value, date input or other

     using such data, the "DATE DATA"), whether falling on, after or before

     calculations, shall process two digit century Date Data and the fields
     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

     efforts to effect an orderly transition of 24/7 Media to another ad serving

     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

                                   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.

NETSCAPE brand online website and information service, including future

                                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.

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.

NETSCAPE shall pay to ADFORCE the Fully Burdened Costs of the provision by 
ADFORCE Personnel of such Technical Support Services plus [*] percent ([*]%) 
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.

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

               (c)  If, following the occurrence of the Implementation Date

          (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.

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

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 $[*] of fees due up to the Prepayment, $[*]
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 [*]% 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 [*]%), 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 [*] ([*]) days after the end of the calendar quarter during 
which such agreement is entered into and within [*] ([*]) 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.

               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;

          (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;

          (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

     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

                                                                  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.

     14.1  TERM.

           14.1.1 TECHNOLOGY LICENSE TERM.  Provided the license grant to

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

obligations of the Parties under this Section 15.3 shall not survive the 
termination of this Agreement.

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.

     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

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 [*]; 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 $[*] 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.

[*] CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED SEPARATELY 
    WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT 
    TO THE OMITTED PORTIONS.

2. OWNERSHIP OF CLIENT AND LIMITATIONS ON USE.  Subject to the terms and 
conditions of this Agreement, NETSCAPE may use the Client on its premises 
solely for purposes of using the AdForce Service. ADFORCE shall at all times 
have sole and exclusive ownership of all right, title and interest in and to 
such Client and the AdForce Service as a whole, any enhancements thereto 
(except as provided in Section 2 above) and in any materials and data ADFORCE 
provides to NETSCAPE. NETSCAPE 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.

3. CONFIDENTIALITY. All 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. All account 
information input into the AdForce Service by NETSCAPE or ADFORCE for 
campaigns running on NETSCAPE Web sites, such as advertiser contacts, costs 
and billing information, and any NETSCAPE campaign-specific reports generated 
by the AdForce Service are confidential to NETSCAPE.

4. ADFORCE SYSTEM DATA.  As set forth in Section 3 above, ADFORCE 
acknowledges the confidentiality of the account information input into the 
AdForce Service by NETSCAPE or ADFORCE for NETSCAPE campaigns and any 
NETSCAPE campaign-specific reports generated by the AdForce Service. However, 
during the course of delivering advertising to visitors to NETSCAPE's sites 
or to any other site of any other ADFORCE customer, ADFORCE will collect and 
maintain information necessary to target advertising on behalf of all its 
customers, including NETSCAPE. This information includes, but is not limited 
to the user's IP address, cookie, browser type and operating system, as well 
as the time, date and ad tag of the request. ADFORCE will provide NETSCAPE 
the ability to run any reports referenced on Exhibit A against such 
information, ADFORCE and NETSCAPE both own all right, title and interest in 
and to such information. Use of such information by either party shall at all 
times comply with NETSCAPE's privacy policy, set forth at 
http://home.netscape.com/legal_notices/privacy.html or at such other URL as 
NETSCAPE may designate from time to time. ADFORCE shall have full freedom of 
use of such information without need for accounting, however, such use shall 
not expand beyond ADFORCE's actual use of such information as of the 
Effective Date. Specifically, ADFORCE will provide to NETSCAPE on a weekly 
basis the detailed HTTP server logs pertaining to user accesses on Netcenter. 
The parties shall mutually agree to a procedure by which such logs will be 
provided to NETSCAPE. Other logs may be requested with reasonable notice by 
Netscape and such requests will not be unreasonably refused by ADFORCE. 
Request for logs not generally provided by ADFORCE shall be subject to the 
terms of Development Services as described in Article 5. All NETSCAPE requests 
for system data will be on a prospective basis.

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 
$[*]. The ADFORCE system must provide:

A.  Average ad delivery availability: [*]%, 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 
    [*]% of a given calendar month, then AdForce's make good shall apply 
    only to the [*]% 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: [*]%, 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 [*] 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 [*] 
    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:
<TABLE>

              FOR THE QUARTER BEGINNING:     THE ESTIMATE IS:
<S>                                          <C>
              February 1, 1999               $[*]
              May 1, 1999                    $[*]
              August 1, 1999                 $[*]
              November 1, 1999               $[*]*
                                             ----------
              TOTAL:                         $[*]
</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 $[*], 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               $[*]
              May 1, 1999                    $[*]
              August 1, 1999                 $[*]
              November 1, 1999               $[*]
</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 [$[*]] multiplied by [[*] if before July 15, [*] if after 
    July 15, 1999, or [*] if Section 6.2(a) controls]

                                      36

    WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT 
    TO THE OMITTED PORTIONS.

3.  Facilities costs will be calculated according to the following formula: 
    [Number of headcount in 1 above] multiplied by [$[*]] multiplied by 
    [[*] if before July 15, [*] if after July 15, 1999, or [*] 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 [[*]] 
             multiplied by [[*]] 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 [[*]] multiplied 
             by [[*]]

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

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

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

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

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

    (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 [[*]].

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.

                                                                CONFIDENTIAL


                             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
