                               PROSPECTUS SUMMARY

    THIS SUMMARY HIGHLIGHTS THE INFORMATION CONTAINED ELSEWHERE IN THIS
PROSPECTUS. BECAUSE THIS IS ONLY A SUMMARY, IT DOES NOT CONTAIN ALL OF THE
INFORMATION THAT MAY BE IMPORTANT TO YOU. YOU SHOULD READ THE ENTIRE PROSPECTUS
CAREFULLY, AND YOU SHOULD CONSIDER THE INFORMATION UNDER "RISK FACTORS" AND IN
THE FINANCIAL STATEMENTS AND NOTES, BEFORE DECIDING TO INVEST IN THE SHARES OF
OUR COMMON STOCK.

    ValueClick is a leading global provider of Internet advertising solutions
for publishers of Web sites and online advertisers. We focus on a
performance-based Internet advertising solution, known as cost-per-click or CPC,
in which an advertiser only pays when an Internet user clicks on its banner
advertisement. This solution provides publishers of Web sites that have low to
moderate rates of traffic, also referred to as small- to medium-sized Web sites,
an opportunity to generate advertising revenue. We also provide publishers of
high-traffic Web sites the ability to capture additional revenue from their
unsold advertising inventory. As a leading aggregator of small- to medium-sized
Web sites, we provide our advertising customers, primarily direct marketing and
e-commerce companies, a cost-effective, low-risk, performance-based Internet
advertising solution.

    The markets for Internet advertising and e-commerce transactions have grown
rapidly in recent years. Forrester Research estimates that in 1998, $1.5 billion
was spent on Internet advertising, and projects that this amount will grow to
$17.2 billion by 2003, a compound annual growth rate of 63%. Additionally, the
Yankee Group expects that e-commerce transactions will increase from $25 billion
in 1998 to $699 billion in 2002, a compound annual growth rate of 130%.

    Historically, most Internet advertising campaigns have been priced based on
a cost-per-thousand impressions model, commonly referred to as CPM. Under the
CPM model, Internet advertisers are charged based on the number of times a
banner advertisement is displayed. This pricing model, which was adopted from
traditional media, is generally associated with advertising campaigns that are
designed to generate brand awareness through widespread exposure to
advertisements. Although CPM has historically been the predominant Internet
advertising model, we believe it has several inefficiencies:

    - Underserves a large number of small- to medium-sized Web sites

    - Frequently leaves unsold advertising inventory

    - Difficulty in predicting effectiveness

    We believe our CPC-based advertising model addresses these inefficiencies by
delivering to Web publishers and advertisers a cost-effective, performance-based
Internet advertising solution. Our solution provides publishers of small- to
medium-sized Web sites the opportunity to generate advertising revenue at little
or no added cost, while allowing publishers of high-traffic Web sites the
ability to capture additional revenue for excess advertising inventory that
would otherwise remain unsold. Our CPC solution also gives Internet advertisers
a convenient way to predict ad effectiveness, because they only pay for visitors
to their sites.

    Our strategy is to be the leading provider of performance-based advertising
solutions by leveraging our position as the largest aggregator of advertising
inventory on small- to medium-sized Web sites and our reputation as the
"Pay-for-Results" advertising network. Key elements of our strategy include:

    - Expand our network of Web sites

    - Grow with our Web publishers

    - Expand our sales and marketing efforts

    - Grow with our Web advertisers

    - Extend our global presence

    - Provide superior customer service

                                       3
<PAGE>
    Our network of Web sites grew over 90% from July 1998 to July 1999, from
approximately 4,200 sites to approximately 8,200 sites, and included over 9,000
Web sites as of August 31, 1999. In August 1999, we delivered over 900 million
banner advertisements, and according to Media Metrix, we reached approximately
one-quarter of all Internet users.

    Our Internet advertising business began in July 1997, as a line of business
within Web-Ignite Corporation. In May 1998, the Internet advertising business of
Web-Ignite was transferred to ValueClick, LLC, a newly-formed California limited
liability company controlled by Web-Ignite's sole stockholder. On December 31,
1998, ValueClick, LLC reorganized as ValueClick, Inc., a Delaware corporation.

    Our principal executive offices are located at 6450 Via Real, Carpinteria,
California 93013. Our telephone number at that location is (805) 684-6060 and
our Web site is www.valueclick.com. Information contained on our Web site does
not constitute part of this prospectus.

                            ------------------------

    In this prospectus, "ValueClick," the "Company," "we," "us" and "our" refer
to ValueClick, Inc., our predecessor business and entities and, after August
1999, our Japanese subsidiary, ValueClick Japan. Unless otherwise indicated, all
information in this prospectus assumes that:

    - the initial public offering price will be $    per share;

    - each share of our preferred stock will be converted into four shares of
      common stock upon the closing of this offering; and

    - the underwriters will not exercise their over-allotment option and no
      other person will exercise any other outstanding option.

                                  RISK FACTORS

    THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD CONSIDER CAREFULLY
THE RISKS AND UNCERTAINTIES DESCRIBED BELOW AND THE OTHER INFORMATION IN THIS
PROSPECTUS BEFORE DECIDING WHETHER TO INVEST IN SHARES OF OUR COMMON STOCK. IF
ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, RESULTS OF OPERATIONS
AND FINANCIAL CONDITION COULD BE MATERIALLY AND ADVERSELY AFFECTED. THIS COULD
CAUSE THE TRADING PRICE OF OUR COMMON STOCK TO DECLINE, AND YOU MIGHT LOSE PART
OR ALL OF YOUR INVESTMENT.

RISKS RELATED TO OUR BUSINESS

OUR SUCCESS DEPENDS ON THE FUTURE VIABILITY OF BANNER ADVERTISING ON THE
  INTERNET AND ITS APPEAL TO DIRECT MARKETING COMPANIES.

    We currently derive substantially all of our revenues by delivering banner
advertisements that generate clicks to our advertisers' Web sites. Sales of
clicks to direct marketing companies account for more than half of these
revenues. This business model may not continue to be effective in the future for
a number of reasons, including the following:

    - click rates have always been low and may decline as the number of banner
      advertisements on the Web increases;

    - Internet users can install "filter" software programs which allow them to
      prevent banner advertisements from appearing on their screens;

    - banner advertisements are, by their nature, limited in content relative to
      other media;

    - direct marketing companies may be reluctant or slow to adopt banner
      advertising that replaces, limits or competes with their existing direct
      marketing efforts; and

    - direct marketing companies may prefer other forms of Internet advertising,
      including permission-based e-mail.

If the number of direct marketing companies who purchase banner clicks from us
does not continue to grow, our business, results of operations and financial
condition could be materially and adversely affected.

OUR UNPROVEN BUSINESS MODEL IS DIFFERENT FROM OTHER INTERNET ADVERTISING
  NETWORKS AND HAS A LIMITED HISTORY.

    We conduct substantially all of our business on a cost-per-click or CPC
pricing model. This business model is relatively new and much less common than
the cost-per-thousand impressions or CPM pricing model, which many other
Internet advertising companies use. Our ability to generate significant revenue
from advertisers will depend, in part, on our ability to:

    - demonstrate the effectiveness of our CPC pricing model to Internet
      advertisers, many of which may be more accustomed to the CPM pricing
      model, and to Web publishers; and

    - attract and retain advertisers and Web publishers by differentiating our
      technology and services from those of our competitors.

    A key component of our strategy is to enhance advertisers' ability to
measure their return on investment and track the performance and effectiveness
of their advertising campaigns. However, we have limited experience in
implementing our strategy. To date, few advertisers have taken advantage of the
most sophisticated tool we offer for tracking Internet users' activities after
they have reached advertisers' Web sites. We cannot assure you that our strategy
will succeed or that we will be able to achieve or maintain adequate margins.

                                       7
<PAGE>
    Intense competition among Web sites and Internet advertising services has
led to the proliferation of a number of alternative pricing models for Internet
advertising. These alternatives, and the likelihood that additional pricing
alternatives will be introduced, make it difficult for us to project the levels
of advertising revenue or the margins that we, or the Internet advertising
industry in general, will realize in the future. Moreover, an increase in the
amount of advertising on the Web may result in a decline in click rates. Since
we predominantly rely on a performance-based pricing model to generate revenue,
any decline in click rates may make our CPC pricing model a less viable or less
attractive solution for Web publishers and advertisers.

OUR ABILITY TO GROW DEPENDS ON EFFECTIVELY MANAGING OUR EXISTING ADVERTISING
  SPACE AND ACQUIRING NEW ADVERTISING SPACE.

    Our success depends in part on our ability to effectively manage our
existing advertising space. The Web sites that list their unsold advertising
space with us are not bound by contracts that ensure us a consistent supply of
advertising space, which we refer to as inventory. In addition, Web sites can
change the amount of inventory they make available to us at any time. If a Web
site publisher decides not to make advertising space from its Web sites
available to us, we may not be able to replace this advertising space with
advertising space from other Web sites that have comparable traffic patterns and
user demographics quickly enough to fulfill our advertisers' requests. This
could result in lost revenues. We expect that our customers' requirements will
become more sophisticated as the Web matures as an advertising medium. If we
fail to manage our existing advertising space effectively, our business, results
of operations and financial conditions could be materially and adversely
affected.

    Our growth is limited by our ability to expand our advertising inventory. In
order to attract new customers, we must maintain a consistent supply of
attractive advertising space. We intend to expand our advertising inventory by
selectively adding to our network new Web sites that offer attractive
demographics, innovative and quality content and growing Web user traffic. Our
ability to attract new Web sites to the ValueClick network and to retain Web
sites currently in our network will depend on various factors, some of which are
beyond our control. These factors include our ability to introduce new and
innovative product lines and services, our ability to efficiently manage our
existing advertising inventory, our pricing policies and the cost-efficiency to
Web publishers of outsourcing their advertising sales. In addition, the number
of competing Internet advertising networks that purchase advertising inventory
from small- to medium-sized Web sites continues to increase. We cannot assure
you that the size of our inventory or the number of Web sites that list their
advertising space on the ValueClick network will increase or even remain
constant in the future.

WE MUST KEEP PACE WITH RAPIDLY CHANGING TECHNOLOGIES.

    The Internet advertising market is characterized by rapidly changing
technologies, evolving industry standards, frequent new product and service
introductions and changing customer demands. The introduction of new products
and services embodying new technologies and the emergence of new industry
standards and practices can render existing products and services obsolete and
unmarketable or require unanticipated investments in research and development.
Our success will depend on our ability to adapt to rapidly changing
technologies, to enhance existing solutions and to develop and introduce a
variety of new solutions to address our customers' changing demands.

    For example, advertisers are increasingly requiring Internet advertising
networks to have the ability to deliver advertisements utilizing new formats
that surpass stationary images and incorporate rich media, such as video and
audio, interactivity, and more precise consumer targeting techniques. Our system
does not support some types of advertising formats, such as video and audio, and
many of the Web sites in our network have not implemented systems to allow rich
media advertisements. In addition, an increase in the bandwidth of Internet
access resulting in faster data delivery may provide new products and services
that will take advantage of this expansion in delivery capability. If we fail to

                                       8
<PAGE>
adapt successfully to developments such as these, our business, results of
operations and financial condition could be materially and adversely affected.

    We purchase most of the software we use in our business from third parties.
We intend to continue to acquire technology necessary for us to conduct our
business from third parties. We cannot assure you that, in the future, these
technologies will be available on commercially reasonable terms, or at all.

    We may also experience difficulties that could delay or prevent the
successful design, development, introduction or marketing of new solutions. Any
new solutions or enhancements we develop will need to meet the requirements of
our current and prospective customers and may not achieve significant market
acceptance. If we fail to keep pace with technological developments and the
introduction of new industry and technology standards on a cost-effective basis,
our business, results of operations and financial condition could be materially
and adversely affected.

THE TECHNOLOGY WE CURRENTLY USE TO TARGET THE DELIVERY OF BANNERS AND TO PREVENT
  FRAUD ON OUR NETWORK IS CONTROVERSIAL.

    Web sites typically place small files of information, commonly known as
"cookies," on an Internet user's hard drive, generally without the user's
knowledge or consent. Cookie information is passed to the Web site through the
Internet user's browser software. We currently use cookies to collect
information about an Internet user's movement through the advertiser's Web site
and to monitor and prevent potentially fraudulent activity on our network. Most
currently available Internet browsers allow Internet users to modify their
browser settings to prevent cookies from being stored on their hard drive, and
some users currently do so. Internet users can also delete cookies from their
hard drives at any time.

    Some Internet commentators and privacy advocates have suggested limiting or
eliminating the use of cookies. The effectiveness of our technology could be
limited by any reduction or limitation in the use of cookies. If the use or
effectiveness of cookies is limited, we would have to switch to other
technologies in order to gather demographic and behavioral information. While
such technologies currently exist, they are substantially less effective than
cookies. We would also have to develop or acquire other technology to prevent
fraud. Replacement of cookies could require significant reengineering time and
resources, might not be completed in time to avoid negative consequences to our
business, results of operations or financial condition, and might not be
commercially feasible.

WE COULD LOSE CUSTOMERS OR ADVERTISING INVENTORY IF WE FAIL TO MEASURE CLICKS ON
  BANNER ADVERTISEMENTS IN A MANNER THAT IS ACCEPTABLE TO OUR ADVERTISERS AND
  WEB PUBLISHERS.

    We earn advertising revenues and make payments to Web publishers based on
the number of clicks on advertisements delivered on our network. Advertisers'
and Web publishers' willingness to use our services and join our network will
depend on the extent to which they perceive our measurements of clicks to be
accurate and reliable. Advertisers and Web publishers often maintain their own
technologies and methodologies for counting clicks, and from time to time we
have had to resolve differences between our measurements and theirs. Any
significant dispute over the proper measurement of clicks or other user
responses to advertisements could cause us to lose customers or advertising
inventory.

WE FACE INTENSE COMPETITION FROM OTHER INTERNET ADVERTISING COMPANIES.

    The market for Internet advertising and related services is intensely
competitive. We expect this competition to continue to increase because there
are no significant barriers to entry. Increased competition may result in price
reductions for advertising space, reduced margins and loss of our market share.
We currently compete with the following types of companies:

                                       9
<PAGE>
    - Internet advertising networks offered by several companies that focus on
      the traditional CPM model, such as DoubleClick, 24/7 Media and Flycast;

    - Internet advertising networks using a performance-based model, like us,
      offered by several smaller companies, such as TeknoSurf and ClickAgents;

    - providers of advertising inventory management products and related
      services, such as NetGravity, Accipiter and AdForce;

    - advertising, media agencies and other companies that facilitate Web
      advertising, such as America Online, NBCi, Yahoo!, SmartAge, GoNetwork,
      Excite@Home, Infoseek, Lycos and Microsoft;

    - Internet navigational, Web search engine companies and informational
      services and online service providers, such as America Online,
      Excite@Home, Lycos, Microsoft, Yahoo!, and Infoseek; and

    - traditional advertising and direct marketing media, such as radio, cable,
      television, print and direct marketing.

    We also compete with traditional advertising media, such as direct mail,
television, radio, cable and print, for a share of advertisers' total
advertising budgets.

    Many of our current and potential competitors enjoy competitive advantages
over us, such as longer operating histories, greater name recognition, larger
customer bases, greater access to advertising space on high-traffic Web sites,
and significantly greater financial, technical and marketing resources. We may
not be able to compete successfully, and competitive pressures may materially
and adversely affect our business, results of operations and financial
condition.

WE MAY FACE COSTLY INTELLECTUAL PROPERTY DISPUTES.

    We may be subject to disputes and legal actions alleging intellectual
property infringement, unfair competition or similar claims against us. As the
number of competitors in our industry grows and as Internet advertising
technologies change over time, we expect that we will be subject to increasing
risk of infringement claims and other intellectual property disputes. Third
parties may have or may in the future be granted patents that cover our
technology. One of our principal competitors, DoubleClick, was recently awarded
a patent on certain aspects of ad-delivery technology, including the ability to
target the delivery of ads over a network such as the Internet and the ability
to compile statistics on individual Web users and the use of those statistics to
target ads. The DoubleClick patent may cover the technology we use in our
advertising solutions. If our technology is not outside the scope of the
technology covered under the DoubleClick patent or if the DoubleClick patent is
not invalidated, we may be limited in our ability to use our technology, may be
sued by DoubleClick for infringement, or may be required to pay for a license to
DoubleClick's technology. We cannot assure you that we could enter into a
licensing agreement with DoubleClick on commercially reasonable terms. Our
failure to prevail in any litigation with DoubleClick or any other party
asserting patent infringement could result in:

    - substantial monetary damages, including damages for past infringement,
      which could be tripled if a court determines that the infringement was
      willful;

    - an injunction requiring us to stop offering our services in their current
      form;

    - the need to redesign our systems; or

    - the need to pay significant license fees in order to use technology
      belonging to third parties.

Furthermore, other third parties may have or may be granted patents or other
proprietary rights that cover our technology or services. We may be limited in
our ability to use our technology or conduct our

                                       10
<PAGE>
business without obtaining licenses from these third parties, which may not be
available on commercially reasonable terms, or at all. See
"Business--Intellectual Property Rights" for more detailed information.

    Any other intellectual property related lawsuit could also subject us to
significant liability for damages, substantial legal costs and business
disruption, and could result in the invalidation of our intellectual property
rights. Any claims or litigation from third parties may also result in
limitations on our ability to use the intellectual property without obtaining
licenses or making other arrangements with the third parties responsible for
those claims or litigation. Arrangements such as these may be unavailable on
commercially reasonable terms, if at all.

    Defending our intellectual property rights, however, may require costly and
disruptive lawsuits and might result in invalidation of our rights. We cannot
assure you that any of our trademark applications will be approved. Even if our
applications are approved, our trademarks may be successfully challenged by
others, or may be invalidated. In addition, despite our efforts to protect our
intellectual property, unauthorized parties may attempt to copy aspects of our
services or to obtain and use information that we regard as proprietary. We may
not have adequate remedies for any breach of confidentiality agreements, and our
trade secrets may otherwise become known or independently developed by
competitors. We have not filed any patent applications to date. We cannot
guarantee that any of our intellectual property rights will be viable or
valuable in the future since the validity, enforceability and scope of
protection of proprietary rights in Internet-related industries is uncertain and
still evolving.

OUR MANAGEMENT IS NEW AND MAY NOT WORK TOGETHER SUCCESSFULLY.

    Our future success depends on the ability of management to implement our
business plan. All executive officers other than Brian Coryat and James R.
Zarley have been directors or officers with us for less than a year. These
recently hired individuals have had limited experience working with the rest of
our management team. We cannot be certain that we will be able to integrate
these new executives into our organization effectively. In addition, our
executive officers may not be successful in carrying out their duties or making
strategic decisions quickly in a rapidly changing market. The failure to
integrate our new executives into our organization or the inability of our
management to respond quickly in the rapidly evolving Internet advertising
market could materially and adversely affect our business, results of operations
and financial condition.

WE DEPEND ON KEY PERSONNEL FOR OUR FUTURE SUCCESS.

    Our future success is substantially dependent on the continued service of
our key senior management, technical and sales personnel and in particular our
Chairman and Chief Executive Officer, James R. Zarley, our President and Chief
Operating Officer, Brian Coryat, and our Vice Chairman and Chief Marketing
Officer Earle A. Malm II. Our employment agreements with our key personnel are
short term and on an at-will basis. We also do not have key-person insurance on
any of our employees, other than Brian Coryat, our President and Chief Operating
Officer. The loss of the services of any member of our management team, or of
any other key employees, could materially and adversely affect our business,
results of operations and financial condition. Our future success also depends
on our continuing 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 attract, assimilate or retain other highly
qualified employees in the future. We have experienced difficulty from time to
time in attracting the personnel necessary to support the growth of our
business, and we may experience similar difficulties in the future.

                                       11
<PAGE>
OUR OFFICERS AND DIRECTORS WILL HAVE SUBSTANTIAL INFLUENCE OVER OUR OPERATIONS.

    We anticipate that our executive officers and directors will beneficially
own approximately     % of our common stock following the completion of this
offering, or      % if the underwriters' over-allotment option is exercised in
full. Our executive officers and directors will have the ability to control all
matters requiring approval by our stockholders, including the election of
directors and approval of significant corporate transactions. These directors
and officers may have interests that are different from, or in addition to, your
interests. See "Principal and Selling Stockholders" for more detailed
information.

SYSTEM FAILURES COULD SIGNIFICANTLY DISRUPT OUR OPERATIONS.

    Our success depends on the continuing and uninterrupted performance of our
systems. Sustained or repeated system failures that interrupt our ability to
provide our services to our customers, including failures affecting our ability
to deliver advertisements quickly and accurately and to process users' responses
to advertisements, would reduce significantly the attractiveness of our
solutions to advertisers and Web sites. Our business, results of operations and
financial condition could be materially and adversely affected by any damage or
failure that interrupts or delays our operations.

    Our computer systems are vulnerable to damage from a variety of sources,
including telecommunications failures, malicious human acts and natural
disasters. We lease server space in Los Angeles, California, Boca Raton, Florida
and Tokyo, Japan. Therefore, any of the above factors affecting the Los Angeles,
Boca Raton or Tokyo areas would substantially harm our business. Moreover,
despite network security measures, our servers are potentially vulnerable to
physical or electronic break-ins, computer viruses and similar disruptive
problems in part because we cannot control the maintenance and operation of our
third-party data centers. Despite the precautions we have taken, unanticipated
problems affecting our systems could cause interruptions in the delivery of our
solutions in the future. Our data storage centers incorporate redundant systems,
consisting of additional servers, but our primary system does not switch over to
our backup system automatically. Our insurance policies may not adequately
compensate us for any losses that may occur due to any failures in our systems.

THE YEAR 2000 PROBLEM COULD CAUSE SIGNIFICANT HARM TO OUR OPERATIONS.

    The Year 2000 problem is the result of many computer systems and software
programs having been designed to accept or recognize only two digits rather than
four digits to define the applicable year. Date sensitive hardware and software
may recognize a date using "00" as the year 1900 rather than the year 2000. As a
result, computer systems and software used by many organizations and
governmental agencies may need to be upgraded to comply with these Year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities.

    The success of our CPC business model depends on our ability to serve a
large number of banner advertisements to our Web publishers and to provide a
large number of clicks to our advertisers. If the Web publishers in our network,
the Internet service providers, or ISPs, who provide access to those Web sites,
or the advertisers whose banner advertisements we serve experience disruptions
in their computer systems related to the Year 2000 problem, we may not be able
to deliver advertisements to our Web publishers or enable Web users to click to
our advertisers, and our business, results of operations and financial condition
could be materially and adversely affected.

    We have completed an assessment of our Year 2000 readiness with respect to
our information and non-information technology systems. Based on the results of
this assessment, we are in the process of addressing any known Year 2000
problems and developing a contingency plan to deal with the Year 2000 problem.
We cannot assure you that we will be successful in our efforts to identify and
remedy by the end of this year all Year 2000 problems that may affect our
systems. Any unforeseen Year 2000

                                       12
<PAGE>
problems may require us to upgrade or replace our systems at a substantial cost,
and may result in our inability to deliver our customers' advertisements to our
network. Our failure to address any unforeseen Year 2000 issue could have a
material and adverse effect on our business, prospects, financial condition and
results of operations. Please see "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Year 2000 Compliance" for more
detailed information on our state of readiness, costs, risks and contingency
plans regarding the Year 2000 problem.

WE MAY EXPERIENCE CAPACITY CONSTRAINTS THAT COULD REDUCE OUR REVENUE.

    Our future success depends in part on the efficient performance of our
software and technology, as well as the efficient performance of the systems of
third parties, such as our ISPs. As the numbers of Web pages and users increase,
our services and infrastructure may not be able to grow to meet the demand. A
sudden and unexpected increase in the volume of advertising delivered through
our servers or in click rates could strain the capacity of the software or
hardware that we have deployed. Any capacity constraints we experience could
lead to slower response times or system failures and adversely affect the
availability of advertisements, the number of advertising views delivered and
the level of user responses received, which would harm our revenues. To the
extent that we do not effectively address capacity constraints or system
failures, our business, results of operations and financial condition could be
harmed substantially. See "Business--Technology Platform" for more detailed
information.

    We also depend on the ISPs that provide consumers with access to the Web
sites on which our customers' advertisements appear. Internet users have
occasionally experienced difficulties connecting to the Web due to failures of
their ISPs' systems. Any disruption in Internet access provided by ISPs or
failures by ISPs to handle the higher volumes of traffic expected in the future
could materially and adversely affect our business, results of operations and
financial condition.

IT MAY BE DIFFICULT FOR YOU TO EVALUATE OUR BUSINESS AND YOUR INVESTMENT BECAUSE
  WE HAVE A LIMITED OPERATING HISTORY.

    Because we have a limited operating history, it may be difficult to evaluate
our business and prospects. You should consider our prospects in light of the
risks, expenses and difficulties frequently encountered by early-stage companies
in the rapidly-changing Internet market. These risks include our ability to:

    - maintain and increase our inventory of advertising space on Web sites;

    - maintain and increase the number of advertisers that use our products and
      services and offer banner advertisements that generate significant
      response rates;

    - continue to expand the number of products and services we offer and the
      capacity of our systems;

    - continue to increase the acceptance of the CPC pricing model; and

    - adapt to changes in Web advertisers' promotional needs and policies, and
      the technologies used to generate Web advertisements.

    If we are unsuccessful in addressing these risks and uncertainties, our
business, results of operations and financial condition could be materially and
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" for more detailed information.

IT MAY BE DIFFICULT TO PREDICT OUR FINANCIAL PERFORMANCE BECAUSE OUR QUARTERLY
  OPERATING RESULTS MAY FLUCTUATE.

    Our revenues and operating results may vary significantly from quarter to
quarter due to a variety of factors, many of which are beyond our control. You
should not rely on period-to-period comparisons

                                       13
<PAGE>
of our results of operations as an indication of our future performance. Our
results of operations may fall below the expectations of market analysts and
investors in some future periods. If this happens, the market price of our
common stock may fall.

    The factors that may affect our quarterly operating results include:

    - fluctuations in demand for our advertising solutions;

    - fluctuations in click rates;

    - fluctuations in the amount of available advertising space, or views, on
      Web sites in the ValueClick network;

    - the timing and amount of sales and marketing expenses incurred to attract
      new advertisers;

    - fluctuations in sales of different types of advertising, for example, the
      amount of advertising sold at higher rates rather than lower rates;

    - changes in our pricing policies, the pricing policies of our competitors
      or the pricing policies for advertising on the Internet generally;

    - timing differences at the end of each quarter between our payments to Web
      publishers for a given set of clicks and our collection of advertising
      revenue for those clicks; and

    - costs related to acquisitions of technology or businesses.

Expenditures by advertisers also tend to be cyclical, reflecting overall
economic conditions as well as budgeting and buying patterns. Any decline in the
economic prospects of advertisers or the economy generally may alter current or
prospective advertisers' spending priorities, or may increase the time it takes
us to close sales with advertisers, and could materially and adversely affect
our business, results of operations and financial condition.

WE MAY EXPERIENCE SEASONAL FLUCTUATIONS IN OUR REVENUES.

    We believe that our revenues will be subject to seasonal fluctuations
because advertisers generally place fewer advertisements during the first and
third calendar quarters of each year. Additional seasonal patterns in Internet
advertisers' spending may emerge as the industry matures.

OUR FUTURE REVENUES AND OPERATING RESULTS ARE DIFFICULT TO FORECAST AND MANY OF
  OUR EXPENSES ARE FIXED.

    Our current and future expense estimates are based, in large part, on our
estimates of future revenues and on our investment plans. In particular, we plan
to increase our operating expenses significantly in order to:

    - expand our sales and marketing operations;

    - enhance our technology and software solutions;

    - acquire additional advertising inventory;

    - enhance our advertising management platform; and

    - continue our international expansion.

Most of our expenses are fixed in the short term. We may be unable to reduce
spending if our revenues are lower than expected. Any significant shortfall in
revenues in relation to our expectations could materially and adversely affect
our business, results of operations and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" for
more detailed information.

WE WILL NEED TO MANAGE OUR GROWTH EFFECTIVELY.

    As we continue to increase the scope of our operations, we will need an
effective planning and management process to implement our business plan
successfully in the rapidly evolving Internet advertising market. Our business,
results of operations and financial condition will be substantially harmed if we
are unable to manage our expanding operations effectively. We commenced
operations, through joint ventures, in Japan in March 1998 and the United
Kingdom in August 1999. We have grown from six employees in July 1998 to 47
full- and part-time employees domestically in September 1999 and have grown to
16 full- and part-time employees in Japan in September 1999. We plan to continue
to expand our sales and marketing, customer support and research and development
organizations. Past growth has placed, and any future growth will continue to
place, a significant strain on our management systems and resources. We have
recently implemented a new financial reporting system and expect that we will
need to continue to improve our financial and managerial controls and our
reporting systems and procedures. In addition, we will need to expand, train and
manage our work force. Our failure to manage our growth effectively could
materially and adversely affect our business, results of operations and
financial condition.

OUR INTERNATIONAL STRATEGY WILL EXPOSE US TO RISKS.

    We initiated operations, through joint ventures, in Japan in March 1998, and
in the United Kingdom in August 1999, and we expect to commence operations in
other selected international markets in 2000. For the six months ended June 30,
1999, international sales represented 12% of our revenues, on a pro forma basis.
Our Japanese operation subjects us to foreign currency exchange risks as it
denominates its transactions in Japanese Yen. Our international expansion will
subject us to additional foreign currency exchange risks and will require
management attention and resources. We expect to pursue expansion through a
number of international alliances and to rely extensively on these business
partners initially to conduct operations, establish local networks, register Web
sites as affiliates and coordinate sales and marketing efforts. Our success in
these markets will depend on the success of our business partners and their
willingness to dedicate sufficient resources to our relationships. We cannot
assure you that we will be successful in our efforts overseas. International
operations are subject to other inherent risks, including:

    - the impact of recessions in economies outside the United States;

    - changes in domestic regulatory requirements, as well as differences
      between domestic and foreign regulatory requirements;

    - export restrictions, including export controls relating to encryption
      technology;

    - reduced protection for intellectual property rights in some countries;

    - potentially adverse tax consequences;

    - difficulties and costs of staffing and managing foreign operations;

    - political and economic instability;

    - tariffs and other trade barriers; and

    - seasonal reductions in business activity.

    Our failure to address these risks adequately could materially and adversely
affect our business, results of operations and financial condition.

RISKS RELATED TO OUR INDUSTRY

WE DEPEND ON THE CONTINUED GROWTH OF INTERNET USAGE AND INFRASTRUCTURE.

    Our business and financial results depend on continued growth in the use of
the Internet. Internet usage may be inhibited for a number of reasons, such as:

    - inadequate network infrastructure;

    - security concerns;

    - inconsistent quality of service; and

    - unavailability of cost-effective, high-speed service.

    If Internet usage grows, its infrastructure may not be able to support the
demands placed on it and its performance and reliability may decline. In
addition, Web sites have experienced interruptions in their service as a result
of outages and other delays occurring throughout the Internet network
infrastructure. 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. If use of the Internet does
not continue to grow, or if the Internet infrastructure does not effectively
support its growth, our business, results of operations and financial condition
could be materially and adversely affected.

OUR LONG-TERM SUCCESS MAY DEPEND ON THE DEVELOPMENT OF E-COMMERCE.

    Because many of our customers' advertisements encourage online purchasing,
our long-term success may depend in part on the growth and market acceptance of
e-commerce. Our business would be adversely affected if the growth or acceptance
of e-commerce does not develop, or develops more slowly than expected. A number
of factors outside of our control could hinder the development of e-commerce,
including the following:

    - the network infrastructure necessary for substantial growth in Internet
      usage may not develop adequately or its performance and reliability may
      decline;

    - insufficient availability of telecommunication services or changes in
      telecommunication services could result in inconsistent quality of service
      or slower response times on the Internet; and

    - negative publicity and consumer concern surrounding the security of
      e-commerce could impede its acceptance and growth.

In particular, any well-publicized compromise of security involving Web-based
transactions could deter people from purchasing items on the Internet, clicking
on advertisements, or using the Internet generally, any of which could
materially and adversely affect our business, results of operations and
financial condition.

WE ARE SUBJECT TO GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES OF DOING
  BUSINESS ON THE WEB.

    Laws and regulations that apply to Internet communications, commerce and
advertising are becoming more prevalent. These regulations could affect the
costs of communicating on the Web and adversely affect the demand for our
advertising solutions or otherwise harm our business, results of operations and
financial condition. Recently, the United States Congress enacted Internet
legislation regarding children's privacy, copyrights and taxation. Other laws
and regulations may be adopted, and may address issues such as user privacy,
pricing, acceptable content, taxation and quality of products and services. This
legislation could hinder growth in the use of the Web generally and decrease the
acceptance of the Web as a communications, commercial and advertising medium. In
addition, the growing use of the Web has burdened the existing
telecommunications infrastructure and has, at times,

                                       16
<PAGE>
caused interruptions in telephone service. Telephone carriers have petitioned
the government to regulate and impose fees on ISPs and online service providers
in a manner similar to long distance carriers.

    Due to the global nature of the Web, it is possible that, although our
transmissions currently originate in California, Florida and Japan, the
governments of other states or foreign countries might attempt to regulate our
transmissions or levy sales or other taxes relating to our activities. The
European Union recently adopted a directive addressing data privacy that may
result in limits on the collection and use of user information. The laws
governing the Internet remain largely unsettled, even in areas where there has
been some legislative action. It may take years to determine whether and how
existing laws, including those governing intellectual property, privacy, libel
and taxation, apply to the Internet and Internet advertising. In addition, the
growth and development of the market for Internet commerce may prompt calls for
more stringent consumer protection laws, both in the United States and abroad,
that may impose additional burdens on companies conducting business over the
Internet. Our business, results of operations and financial condition could be
materially and adversely affected by the adoption or modification of laws or
regulations relating to the Internet, or the application of existing laws to the
Internet or Internet-based advertising.

WE MAY BE LIABLE FOR CONTENT DISPLAYED ON THE WEB SITES OF OUR PUBLISHERS.

    We may be liable to third parties for content in the advertising we deliver
if the artwork, text or other content involved violates copyright, trademark, or
other intellectual property rights of third parties or if the content is
defamatory. Any claims or counterclaims could be time-consuming, result in
costly litigation or divert management's attention.

WE MAY BE LIABLE FOR OTHER ACTIVITIES OF OUR INTERNET ADVERTISERS.

    A wide variety of laws govern the content of advertisements and regulate the
sale of goods and services. It is uncertain whether or how these laws may apply
to advertising or e-commerce. We cannot predict whether our role in delivering
advertisements will expose us to liability.

RISKS RELATED TO THIS OFFERING

VIRTUALLY ALL OF OUR SHARES WILL BE ELIGIBLE FOR SALE SHORTLY AFTER THIS
  OFFERING, WHICH COULD RESULT IN A DECLINE IN OUR STOCK PRICE.

    If our stockholders sell substantial amounts of common stock in the public
market following this offering, the market price of our common stock could fall.
These sales also might make it more difficult for us to sell equity or
equity-related securities in the future at a time and price that we deem
appropriate. Based on shares outstanding as of September 30, 1999, upon
completion of this offering, we will have            shares of common stock
outstanding. Of these shares, the         shares being offered hereby will be
freely tradable and the remaining shares will become eligible for sale in the
public market at various times after the date of this prospectus pursuant to
Rule 144. Substantially all of these remaining shares are subject to contractual
restrictions with the underwriters that prevent them from being sold until 180
days after the date of this prospectus without the consent of Volpe Brown Whelan
& Company, LLC.

    In addition, upon the effective date of this offering, we expect to register
for sale 8,000,000 shares of common stock reserved for issuance under the 1999
Stock Option Plan. As of September 30, 1999, options to purchase 5,489,200
shares of common stock were outstanding. Shares acquired upon exercise of these
options will be eligible for sale in the public market from time to time subject
to vesting and the 180-day lockup restrictions that apply to the outstanding
stock. The exercise price of all of these stock options is lower than the
expected initial public offering price of our common stock. The sale of

                                       17
<PAGE>
a significant number of these shares could cause the price of our common stock
to decline. See "Shares Eligible for Future Sale" for more detailed information.

WE EXPECT TO EXPERIENCE VOLATILITY IN OUR STOCK PRICE.

    Prior to this offering, there has been no public market for our common
stock. Accordingly, we cannot assure you that an active trading market will
develop or be sustained or that the market price of our common stock will not
decline. The initial public offering price for the shares will be determined by
us and the representatives of the underwriters and may not be indicative of
prices that will prevail in the trading market. The price at which our common
stock will trade after this offering is likely to be highly volatile and may
fluctuate substantially due to factors such as:

    - actual or anticipated fluctuations in our results of operations;

    - changes in securities analysts' expectations, or our failure to meet those
      expectations;

    - announcements of technological innovations;

    - introduction of new services by us or our competitors;

    - developments with respect to intellectual property rights;

    - conditions and trends in the Internet and other technology industries; and

    - general market conditions.

    In addition, the stock market has from time to time experienced significant
price and volume fluctuations that have affected the market prices for the
common stocks of technology companies, particularly Internet companies. In the
past, these broad market fluctuations have been unrelated or disproportionate to
the operating performance of these companies. Any significant fluctuations in
the future might result in a decline in the market price of our common stock. In
the past, following periods of volatility in the market price of a particular
company's securities, securities class action litigation has often been brought
against that company. We may become involved in this type of litigation in the
future. Litigation is often expensive and diverts management's attention and
resources, which could harm our business and operating results.

WE WILL HAVE BROAD DISCRETION IN USE OF THE PROCEEDS FROM THIS OFFERING.

    We estimate that the net proceeds from this offering will be approximately
$      million. The net proceeds will be used for general corporate purposes and
none of the net proceeds have been designated for a particular purpose. Our
management can therefore spend most of the proceeds from this offering in ways
with which stockholders may not agree. See "Use of Proceeds" for more detailed
information.

WE HAVE ADOPTED ANTI-TAKEOVER PROVISIONS THAT COULD DELAY OR INHIBIT THE SALE OF
  VALUECLICK.

    Provisions of our Certificate of Incorporation, our Bylaws and Delaware law
could make it more difficult for a third party to acquire us, even if doing so
would be beneficial to our stockholders. See "Description of Capital
Stock--Delaware Anti-Takeover Law and Charter and Bylaw Provisions" for more
detailed information.

                           FORWARD-LOOKING STATEMENTS

    This prospectus contains forward-looking statements that involve risks and
uncertainties. You should not rely on these forward-looking statements. We use
words such as "anticipates," "believes," "plans," "expects," "future," "intends"
and similar expressions to identify forward-looking statements. Our actual
results could differ materially from those anticipated in these forward-looking
statements for many reasons, including the risks faced by us and described in
the preceding "Risk Factors" section and elsewhere in this prospectus. This
prospectus also contains forward-looking statements attributed to third parties
relating to their estimates regarding the growth of Internet use, e-commerce and
Internet advertising. We have not attempted to verify the information provided
by third parties.

    In evaluating our business, prospective investors should consider carefully
the factors presented in the "Risk Factors" section and the other information
contained in this prospectus.

                                USE OF PROCEEDS

    The net proceeds to us from the sale of the       shares being offered by us
at an assumed initial public offering price of $      per common share, after
deducting estimated underwriting discounts and commissions and estimated
offering expenses, are estimated to be $      , or $      if the underwriters'
over-allotment option is exercised in full. We expect to use the net proceeds of
the offering for general corporate purposes, including expansion of sales and
marketing activities, enhancement of our technology, possible acquisitions and
international expansions. Pending these uses, we intend to invest the net
proceeds in short-term, interest-bearing, investment grade securities.

                                DIVIDEND POLICY

    We currently anticipate that we will retain any future earnings for use in
our business. As a result, we do not anticipate paying any cash dividends in the
foreseeable future. Any determination to pay dividends in the future will be at
the discretion of our board of directors and will depend upon, among other
factors, our results of operations, financial condition and capital
requirements.

                                    DILUTION

    Our pro forma net tangible book value as of June 30, 1999 was approximately
$0.14 per share of common stock. Net tangible book value per share represents
the amount of our total tangible assets reduced by the amount of our total
liabilities and divided by the total number of shares of common stock
outstanding. After giving effect to the sale of the shares of common stock
offered by us at an assumed initial public offering price of $   per common
share after deducting estimated underwriting discounts and commissions and
estimated offering expenses, our pro forma net tangible book value as of June
30, 1999 would have been $   per common share of common stock. This represents
an immediate increase in net tangible book value of $   per common share to
existing stockholders and an immediate dilution of $   per share to new
investors. The following table illustrates this per share dilution:

option or issuance of shares underlying outstanding options. As of June 30,
1999, options to purchase 4,815,200 shares of common stock were outstanding at a
weighted average exercise price of $0.35 per share. To the extent that these
options are exercised, new investors will experience further dilution. See
"Description of Capital Stock" on page 50 and Notes 1 and 9 of the notes to our
financial statements for more information on our capital stock and further
dilution you may experience.

- ------------------------

(1) If the underwriters' over-allotment option is exercised in full, sales by
    the selling stockholders in this offering will reduce the number of shares
    of common stock held by existing stockholders to 30,175,152 or approximately
      % of total shares of common stock outstanding after this offering.

as of December 31, 1997 and statement of operations data for the period July 1,
1997 through December 31, 1997 and the four months ended April 30, 1998 have
been derived from the audited financial statements of the ValueClick line of
business of Web-Ignite Corporation appearing elsewhere in this prospectus. The
selected balance sheet data as of December 31, 1998 and the selected statement
of operations data for the period from May 1, 1998 (inception) through December
31, 1998 have been derived from the audited financial statements of ValueClick,
Inc. appearing elsewhere in this prospectus. The selected balance sheet data as
of June 30, 1999 and the selected Statement of Operations Data for the six
months ended June 30, 1999 have been derived from the unaudited financial
statements of ValueClick, Inc. appearing elsewhere in this prospectus. The
combined historical selected financial data for the six months ended June 30,
1998 and the twelve months ended December 31, 1998 reflect the combined selected
financial data of ValueClick, Inc. for the period May 1, 1998 through June 30,
1998 and the ValueClick line of business of Web-Ignite Corporation for the four

unaudited financial statements contain all adjustments necessary to present
fairly the information included in those statements, and that the adjustments
consist only of normal recurring adjustments. Operating results for the six
months ended June 30, 1999 are not necessarily indicative of the results that
may be expected for the year ending December 31, 1999.

    The pro forma selected balance sheet data as of June 30, 1999 and the pro
forma selected statement of operations data for the six months ended June 30,
1999 have been derived from the unaudited pro forma condensed consolidated

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF THE COMPANY SHOULD BE READ IN CONJUNCTION WITH "SELECTED FINANCIAL
DATA" AND THE COMPANY'S FINANCIAL STATEMENTS AND THE RELATED NOTES THERETO. THIS
DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM
HISTORICAL RESULTS OR ANTICIPATED RESULTS INCLUDING THOSE SET FORTH IN "RISK
FACTORS" AND ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    We focus on a performance-based Internet advertising solution, known as
cost-per-click or CPC, in which an advertiser only pays when a user clicks on
the advertiser's banner advertisement. As an aggregator of over 9,000 small- to
medium-sized Web sites, we provide our advertising customers, primarily
e-commerce and direct marketing companies, a cost-effective, low-risk Internet
advertising solution. Our solution provides publishers of small- to medium-sized
Web sites the opportunity to generate advertising revenues. We also provide
publishers of large Web sites the ability to capture incremental revenues from
their unsold advertising inventory.

    Our Internet advertising business began in July 1997, as a line of business
within Web-Ignite Corporation. In May 1998, the Internet advertising business of
Web-Ignite was transferred to ValueClick, LLC, a newly-formed California limited
liability company controlled by Web-Ignite's sole stockholder. On December 31,
1998, ValueClick, LLC reorganized as ValueClick, Inc., a Delaware C-corporation.

    We generate revenues by delivering advertisements to Web sites in the
ValueClick network. Pricing of our advertising is on a cost-per-click basis and
varies depending on whether advertising is delivered across our entire network
or across targeted categories within our network. At this time, substantially
all of our revenues are derived from advertising delivered across our entire
network. We sell our services through our sales and marketing staff located in
Carpinteria, California and Tokyo, Japan. The advertisements we deliver are sold
under short-term agreements that are subject to cancellation. Advertising
revenue is recognized in the month that clicks on delivered advertisements
occur, provided that no significant obligations on our part remain and
collection of the related receivable is probable. To date, our agreements have
not required guaranteed minimum click-throughs. We pay each Web site in the
ValueClick network a price-per-click, which is based upon the volume of clicks
delivered by the Web site in a given month. These payments made to Web
publishers are included in the cost of revenues.

    We expect to generate most of our revenues in the foreseeable future from
Internet banner advertising. Our ten largest advertisers accounted for 77% of
our revenues for the period from May 1, 1998 (inception) through December 31,
1998 and 45% of our revenues for the six months ended June 30, 1999. For the six
months ended June 30, 1999, no single advertiser accounted for more than 10% of
our revenues and no Web site contributed more than 10% of our advertising
inventory, as measured by the number of clicks generated by each Web site in the
ValueClick network.

    In light of the rapidly evolving nature of our business and our limited
operating history, we believe that period-to-period comparisons of our operating
results are not meaningful and that the results for any period should not be
relied upon as an indication of future performance. We expect to increase
significantly our operating expenses in order to expand our sales and marketing
operations, to enhance our network technologies and to continue our
international expansion.

ACQUISITION OF VALUECLICK JAPAN

    Prior to August 6, 1999, we had a 32% ownership interest in ValueClick
Japan, which was accounted for using the equity method of accounting. On August
6, 1999, we purchased an additional 22% of ValueClick Japan stock in exchange
for 640,000 shares of our common stock, giving us a 54% controlling ownership
interest in ValueClick Japan. The acquisition will be accounted for using the
purchase method. The purchase price will be allocated to the estimated fair
value of assets acquired and liabilities assumed, to the extent acquired by us.
The remaining portion of the ValueClick Japan assets and liabilities will be
recorded at the historical cost basis of the minority stockholders.

(1) The combined historical statement of operations for the six months ended
    June 30, 1998 reflects the combined results of our operations for the period
    from May 1, 1998 through June 30, 1998 and the ValueClick line of business
    of Web-Ignite for the four months ended April 30, 1998.

  REVENUES

    Our revenues are derived primarily from the sale of clicks on banner
advertisements delivered through the ValueClick network. We charge our
advertisers on a cost-per-click basis, when a consumer clicks on the
advertiser's banner ad. We had revenues of $2.1 million for the period from May
1, 1998 (inception) through December 31, 1998. Our revenues were $4.9 million
for the six months ended June 30, 1999 as compared to $450,000 for the combined
historical six months ended June 30, 1998. The increase was due to the growth of
the ValueClick network and our ability to serve a larger advertiser customer
base.

                                       24
<PAGE>
  COST OF REVENUES

    Cost of revenues consists primarily of amounts we pay to Web sites on the
ValueClick network. We pay these Web sites on a cost-per-click basis. Cost of
revenues also includes depreciation costs of the advertising delivery system and
Internet access costs. Our cost of revenues was $1.1 million for the period from
May 1, 1998 (inception) through December 31, 1998. For the six months ended June
30, 1999 our cost of revenues was $2.4 million compared to $181,000 for the
combined historical six months ended June 30, 1998. The $2.2 million increase
was directly attributable to the increased delivery of banner advertisements and
clicks on banner advertisements.

  SALES AND MARKETING

    Sales and marketing expenses consist primarily of compensation (including
commissions), travel, advertising, trade show costs and costs of marketing
materials. Our sales and marketing expenses were $516,000 for the period from
May 1, 1998 (inception) through December 31, 1998. For the six months ended June
30, 1999 our sales and marketing expenses were $648,000 compared to $55,000 for
the combined historical six months ended June 30, 1998. Along with the
significant growth of the ValueClick network, we added sales and marketing
personnel to extend our sales reach. The increase in personnel and related sales
and marketing activity resulted in a significant increase in sales and marketing
expenses. We expect sales and marketing expenses to continue to increase in
future periods as we hire additional personnel in sales and marketing, open
additional sales offices in major domestic markets, expand into international
markets and continue to promote our advertising solutions.

  GENERAL AND ADMINISTRATIVE

    General and administrative expenses consist primarily of compensation and
professional service fees. We had general and administrative expenses of
$404,000 for the period from May 1, 1998 (inception) through December 31, 1998.
For the six months ended June 30, 1999 we had general and administrative
expenses of $954,000 compared to $208,000 for the combined historical six months
ended June 30, 1998. The $746,000 increase in the comparable periods was
primarily attributable to increased executive and administrative headcount. In
addition, we incurred related expenses associated with hiring additional
personnel, expanding our corporate offices to accommodate our increased
personnel and other professional service expenses that were not incurred in
1998. We expect general and administrative expenses to increase in future
periods as we hire additional personnel and incur additional costs related to
the growth of our business and our operations as a public company.

  TECHNOLOGY ENHANCEMENTS

    Technology enhancement costs include expenses for the development of new
technologies designed to enhance the performance of our service, including the
salaries and related expenses for our software engineering department, as well
as costs for contracted services, supplies and equipment. To date, all product
development costs have been expensed as incurred. We had technology enhancement
expenses of $155,000 for the period from May 1, 1998 (inception) through
December 31, 1998. For the six months ended June 30, 1999, we had technology
enhancement expenses of $321,000 compared to $15,000 on a combined historical
basis for the six months ended June 30, 1998. The increase was primarily
attributable to the hiring of additional software engineers. We believe that
continued investment in technology enhancement is critical to attaining our
strategic objectives and, as a result, we expect technology enhancement expenses
to increase in future periods.

  STOCK-BASED COMPENSATION

    In connection with the grant of stock options to employees during the six
months ended June 30, 1999, we recorded total deferred compensation of
approximately $2.7 million. This deferred

                                       25
<PAGE>
compensation represented the difference between the deemed fair value of our
common stock for accounting purposes and the exercise price of these options at
the date of grant, resulting in an expense charge of $298,000 for the six months
ended June 30, 1999 related to amortization of this deferred compensation.
Deferred compensation is presented as a reduction of stockholders' equity and
amortized over the vesting period of applicable options, generally four years.

    Annual amortization of deferred stock compensation for options granted as of
June 30, 1999 is estimated to be approximately $1,238,000 for the year ending
December 31, 1999, $1,023,000 for the year ending December 31, 2000, $326,000
for the year ending December 31, 2001, $109,000 for the year ending December 31,
2002, and $15,000 for the year ending December 31, 2003. In addition, certain
employees have options that have accelerated vesting upon certain events,
including the closing of this offering or the transfer of ownership of 50% or
more of our stock. Assuming the closing of this offering by December 31, 1999,
we believe that the amortization of deferred stock compensation for the years
listed above would not be significantly different than the amounts presented
above.

  INTEREST INCOME (EXPENSE)

    Interest income consists of interest earned on our cash and cash
equivalents. Interest expense consists of interest paid on capital lease and
debt obligations. Interest income was $8,000 for the period from May 1, 1998
(inception) through December 31, 1998 and $20,000 for the six months ended June
30, 1999. Interest expense was $0 for the period from May 1, 1998 (inception)
through December 31, 1998 and $1,000 for the six months ended June 30, 1999. No
interest expense was incurred for the combined historical six months ended June
30, 1998.

  INCOME TAXES

    For the period from May 1, 1998 (inception) through December 31, 1998, we
were a limited liability company, or LLC, and as such, were subject to the
provisions of Subchapter K of the Internal Revenue Code. Under those provisions,
we did not pay Federal income taxes on any taxable income. Instead, the members
of the LLC were liable for individual Federal income taxes on our taxable
income. Upon conversion to a C-corporation on December 31, 1998, we commenced
using the asset and liability method of accounting for income taxes. Our
conversion from an LLC to a C-corporation did not have a material impact on our
financial position or results of operations. Following the conversion, we have
been operating as a C-corporation and are subject to Federal and state income
taxes. For the six months ended June 30, 1999, our provision for Federal and
state income taxes amounted to $216,000. No provision has been recorded for the
combined historical six months ended June 30, 1998 as the predecessor entity was
taxed as an S-corporation and we were taxed as an LLC.

QUARTERLY RESULTS OF OPERATIONS

    The following tables sets forth unaudited quarterly statement of operations
data and the percentages of revenue for the last three quarters of 1998 and the
first two quarters of 1999. The unaudited combined historical statement of

the combined results of operations of the ValueClick line of business of Web-
Ignite for the three months ended March 31, 1998 and ValueClick for the period
from May 1, 1998 through June 30, 1998 and the ValueClick line of business of
Web-Ignite for the one month ended April 30, 1998. In the opinion of management,
this information has been prepared on the same basis as the audited financial
statements appearing elsewhere in this prospectus, and all necessary
adjustments, consisting only of normal recurring adjustments, have been included
in the amounts stated below to present fairly the unaudited quarterly results of
operations. The quarterly data should be read in conjunction with our audited
financial statements and the notes to the financial statements appearing

    Our revenues increased in each quarter presented due to an increase in the
number of advertisements delivered on the ValueClick network. Cost of revenues
as a percentage of revenues decreased in the last two quarters due to a greater
increase in the average cost-per-click charged to advertisers than the
cost-per-click paid to Web sites. Operating expenses increased in absolute
dollars but decreased as a percentage of revenues in each quarter in 1998 and
the first quarter of 1999. In the second quarter of 1999, operating expenses
increased as a percentage of revenues. Sales and marketing expenses increased as
a result of increased sales personnel and commissions and increased advertising
and promotion. Technology enhancement expenses increased as a result of the
hiring of additional software engineers and the continued development of
technology. General and administrative expenses increased primarily due to
additional personnel and professional fees.

    We believe that our revenues will be subject to seasonal fluctuations
because advertisers generally place fewer advertisements during the first and
third calendar quarters of each year. In addition, expenditures by advertisers
tend to be cyclical, reflecting overall economic conditions as well as budgeting
and buying patterns. In addition, our results of operations may fluctuate
significantly in the future as a result of a variety of factors, many of which
are beyond our control. See "Risk Factors--It may be difficult to predict our
financial performance because our quarterly operating results may fluctuate" and
"--We may experience seasonal fluctuations in our revenues."

LIQUIDITY AND CAPITAL RESOURCES

    Since our inception, we have financed our operations through working capital
generated from operations and private equity financings, raising $4.3 million
through June 30, 1999. Net cash used in operating activities was approximately
$717,000 for the six months ended June 30, 1999, which resulted principally from
increases in accounts receivable of $1.9 million partially offset by net income
and increases in income taxes payable and deferred revenue.

    Net cash used in investing activities for the six months ended June 30, 1999
was $433,000 representing an additional equity investment of $263,000 in
ValueClick Japan and the purchase of $170,000 of fixed assets.

    Net cash provided by financing activities during the six months ended June
30, 1999 represented the net proceeds from the sale of our Series C preferred
stock for $3.5 million.

    We believe that our existing cash and cash equivalents combined with
proceeds from this offering will be sufficient to meet our anticipated cash
needs for working capital and capital expenditures for the next 12 months.

YEAR 2000 COMPLIANCE

    Our business depends on our ability to serve a large number of banner
advertisements to our Web publishers and to provide a large number of clicks to
our advertisers. If the Web publishers in our network, the Internet service
providers, or ISPs, who provide access to those Web sites, or the advertisers
whose banner advertisements we serve experience disruptions in their computer
systems related to the Year 2000 problem, we may not be able to deliver
advertisements to our Web publishers or clicks to our advertisers, and our
business could be harmed substantially.

    The Year 2000 problem results from computer programs and hardware designed
to use the last two digits rather than all four digits to define the applicable
year. As a result, these systems may recognize a date using "00" as the year
1900 rather than the year 2000. If these systems are not made Year 2000
compliant, they could create erroneous information causing us or our customers
or suppliers to become unable to process normal business transactions accurately
or at all.

                                       28
<PAGE>
    STATE OF READINESS.  We have completed an assessment of our Year 2000
readiness and believe that all of our computer programs and hardware are Year
2000 compliant. Our Year 2000 readiness assessment included the following
overlapping phases:

    - Identification--The identification of all of our internal hardware and
      software systems as well as our key third party relationships that may be
      affected by the Year 2000 issue (including advertisers, Web publishers,
      suppliers, and co-location facilities among others).

    - Analysis--An evaluation of the impact and magnitude of any potential Year
      2000 problems for all of our previously identified items.

    - Conversion and Implementation--The development and execution of a plan to
      bring any identified non-Year 2000 compliant items into compliance,
      including the conversion, upgrade or replacement of any non-Year 2000
      compliant systems.

    - Testing--The continuous testing of our systems to determine their Year
      2000 compliance after any necessary Year 2000 remediations.

    Based our Year 2000 readiness assessment, we believe that that all of our
non-information technology, including security and phone systems, upon which we
are materially dependent is Year 2000 compliant. We also believe that our
information technology systems, including our internally developed software, are
not sensitive to any Year 2000 risks. Although we have not discovered any
material Year 2000 problems with our internal information technology to date, we
may in the future.

    We have sent out inquiries to our key external business partners and vendors
of hardware and software we use regarding their own Year 2000 readiness. Based
on their responses and based on our own internal testing of the third party
hardware and software we use, we believe that our key external business partners
and vendors are Year 2000 compliant. We cannot assure you, however, that we will
not experience unanticipated consequences, including material costs caused by
undetected errors or defects in the technology used in our internal systems.

    COSTS TO ADDRESS OUR YEAR 2000 COMPLIANCE.  To date, we have not incurred
any material expenditure in connection with identifying, evaluating, or
remediating any Year 2000 compliance issues. However, if we discover any Year
2000 issue, the costs of remediating the problem could be higher than
anticipated and could harm our business, results of operations and financial
condition.

    RISKS.  We are not currently aware of any additional significant Year 2000
compliance problems relating to our software, our information technology systems
or other systems that would materially harm our business, results of operations
or financial conditions. During our ongoing assessment, we may discover Year
2000 compliance problems that may require substantial repair or replacement
which could cause our business to suffer. In addition, our customers' ability to
deliver advertisements over our network may be disrupted if the software and
hardware products used by Web publishers, advertisers, governmental agencies,
public utilities, telecommunications companies and others are not Year 2000
compliant. We also depend on the uninterrupted availability of the Internet
infrastructure to conduct our business. Year 2000 problems affecting the
Internet could result in significant harm to our business, results of operations
and financial condition.

    CONTINGENCY PLAN.  We are currently in the process of developing a
contingency plan to deal with Year 2000 problems. We expect to complete our Year
2000 contingency plan by October 31, 1999. We intend to actively work with and
encourage our suppliers to minimize the risks of business disruptions resulting
from Year 2000 issues and develop contingency plans where necessary. If our
present efforts to become Year 2000 compliant are not successful, or if our Web
publishers, suppliers and other third parties do not successfully become Year
2000 compliant, our business, results of operations and financial condition
could be harmed.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    We do not hold any derivative instruments and do not engage in hedging
activities. Also, we do not hold any variable interest rate debt or lines of
credit and thus have minimal exposure to interest rate fluctuations.

    Our equity investment in ValueClick Japan subjects us to foreign currency
exchange risks as ValueClick Japan denominates its transactions in the Japanese
Yen. Our exposure is limited to the extent of our equity investment in
ValueClick Japan, which represented 7.5% and 5.5% of our total assets at
December 31, 1998 and June 30, 1999, respectively. Historically, we have not
hedged our exposure to exchange rate fluctuations. Accordingly, we may
experience economic loss and a negative impact on earnings or equity as a result
of foreign currency exchange rate fluctuations.

RECENTLY ISSUED ACCOUNTING STANDARDS

    In March 1998, the Accounting Standards Executive Committee issued Statement
of Position No. 98-1, or SOP 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," which provides guidance on
accounting for the cost of computer software developed or obtained for internal
use. SOP 98-1 is effective for financial software statements for fiscal years
beginning after December 15, 1998. Implementation of SOP 98-1 did not have a
significant impact on our financial position, results of operations or cash
flows.

    In April 1998, the Accounting Standards Executive Committee issued Statement
of Position No. 98-5, or SOP 98-5, "Reporting on the Costs of Start-Up
Activities." This standard requires companies to expense the costs of start-up
activities and organization costs as incurred. In general, SOP 98-5 is effective
for fiscal years beginning after December 13, 1998. Adoption of SOP 98-5 did not
have a significant impact on our financial position, results of operations or
cash flows.

    In June 1998, the Accounting Standards Executive Committee issued Statement
of Accounting Standards No. 133, or SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS 133 establishes new standards of
accounting and reporting for derivative instruments and hedging activities. SFAS
133 requires that all derivatives be recognized at fair value in the statement
of financial position, and that the corresponding gains and losses be reported
either in the statement of operations or as a component of comprehensive income,
depending on the type of hedging relationship that exists. SFAS 133 will be
effective for fiscal years beginning after June 15, 2000. We do not currently
hold derivative instruments or engage in hedging activities. Accordingly,
management believes the adoption of this statement will not have a significant
impact on our financial position, results of operations or cash flows.

OVERVIEW

    ValueClick is a leading global provider of Internet advertising solutions
for publishers of Web sites and online advertisers. We focus on a
performance-based Internet advertising solution, known as cost-per-click or CPC,
in which an advertiser only pays when an Internet user clicks on its banner
advertisement. This solution provides publishers of Web sites that have low to
moderate rates of traffic, also referred to as small- to medium-sized Web sites,
an opportunity to generate advertising revenue. We also provide publishers of
high-traffic Web sites the ability to capture additional revenue from their
unsold advertising inventory. As the leading aggregator of small- to
medium-sized Web sites, we provide our advertising customers, primarily direct
marketing and e-commerce companies, a cost-effective, low risk Internet
advertising solution. In August 1999, we delivered in excess of 900 million Web
advertisements and our network consisted of more than 9,000 Web sites. According
to Media Metrix, we reached approximately one-quarter of all Internet users in
August 1999.

INDUSTRY BACKGROUND

    THE INTERNET

    The Internet has developed into a global medium for interactive content,
communications and commerce that has changed the face of business worldwide. In
recent years, the Internet has experienced substantial growth in the number of
users and Web sites, the volume of e-commerce transactions and the amount of
advertising dollars spent. Jupiter Communications estimates that in 1996, 15.1
million or 15.3% of U.S. households were Internet users, compared to 44.9
million or 44.1% in 1999, and projects that Internet use will grow to 67.6
million or 63.4% of U.S. households by 2003. The Yankee Group estimates that the
number of people using the Internet worldwide will grow from 140 million in 1998
to over 570 million by the end of 2003.

    INTERNET ADVERTISING AND E-COMMERCE

    The Internet has emerged as an attractive new medium for advertisers due to
its significant growth in number of users and volume of e-commerce transactions,
and also due to the unique characteristics of the Internet as compared with
other advertising media. These characteristics include the potential for
Internet advertisers to establish dialogues and direct relationships with
potential customers, receive immediate feedback on advertising campaigns and
adapt them quickly to respond to this feedback. As a result, Internet
advertising and e-commerce transactions have grown rapidly in recent years.
Forrester Research estimates that in 1998, $1.5 billion was spent on Internet
advertising, and projects that this amount will grow to $17.2 billion by 2003, a
compound annual growth rate of 63%. Additionally, the Yankee Group expects that
e-commerce transactions will increase from $25 billion in 1998 to $699 billion
in 2002, a compound annual growth rate of 130%.

    THE EVOLUTION OF INTERNET ADVERTISING

    Historically, most Internet advertising campaigns have been priced based on
a cost-per-thousand impressions model, commonly referred to as CPM. Under the
CPM model, Internet advertisers are charged based on the number of times a
banner advertisement is displayed. This pricing model, which was adopted from
traditional media, is generally associated with advertising campaigns that are
designed to generate brand awareness through widespread exposure to
advertisements.

    Although CPM has historically been the predominant Internet advertising
model, we believe that the CPM model has several inefficiencies:

    - UNDERSERVES A LARGE NUMBER OF SMALL- TO MEDIUM-SIZED WEB SITES. Because
      small- to medium-sized Web sites typically serve more targeted audiences
      than large Web sites, they individually cannot drive enough traffic to
      appeal to CPM advertisers. These sites are often disregarded as an

                                       31
<PAGE>
      advertising outlet because it is not cost-effective for CPM advertisers to
      manage a large number of small media buys and audit these sites for
      traffic and appropriate content.

    - FREQUENTLY LEAVES UNSOLD ADVERTISING INVENTORY. In order to support their
      CPM pricing structure, high-traffic Web sites that attract CPM advertisers
      are frequently left with large amounts of unsold inventory. This unsold
      inventory represents an incremental revenue opportunity for large Web
      sites, however, discounting rates to sell this inventory could lead to a
      decline in CPM rates that publishers want to avoid.

    - DIFFICULTY IN PREDICTING EFFECTIVENESS. With CPM, an advertiser pays each
      time its banner is "loaded" or displayed without knowing whether the
      displayed advertisement will generate responses or be converted into
      sales. This uncertainty makes it difficult for advertisers to predict the
      actual return on their Internet advertising dollars.

    Due in part to these inefficiencies, we believe that Internet advertisers,
especially direct marketing and e-commerce based companies, are increasingly
seeking performance-based alternatives to the CPM model. Performance-based
advertising is intended to generate a specific or direct response or action from
a consumer and is designed to maximize the number of responses per advertising
dollar. These responses can include a simple electronic reply by the consumer,
registration of the consumer and actual purchases. Forrester Research projects
that performance-based advertising models will account for 50% of online
advertising budgets by 2003, up from 15% in 1999.

    The Web is particularly well-suited for direct response advertising. Reading
and clicking on a Web advertisement is easier and more convenient for many
consumers than traditional direct response advertising mechanisms such as
toll-free numbers or business reply cards. Web advertisements also allow
consumers to respond immediately to advertising and interact directly with the
advertiser in real-time. Advertisers can also use this feedback to rapidly
adjust their advertising campaigns.

THE VALUECLICK SOLUTION

    We believe our CPC-based advertising model delivers to Web publishers and
advertisers a cost-effective, performance-based Internet advertising solution.
Our solution provides publishers of small- to medium-sized Web sites the
opportunity to generate advertising revenue at little or no added cost while
allowing publishers of high-traffic Web sites the ability to capture additional
revenue for excess advertising inventory that would otherwise remain unsold. Our
CPC solution also gives Internet advertisers a convenient way to predict ad
effectiveness, because they only pay for visitors to their sites.

    We have developed highly automated systems and processes which make it easy
for publishers of small- to medium-sized Web sites to join the ValueClick
network and an effective publisher referral program that facilitates growth and
retention of publishers. By cost-effectively aggregating this underutilized
inventory, we have developed a very low cost solution for advertisers to access
the visitors of these quality sites. Our network of Web sites grew over 90% from
July 1998 to July 1999 from approximately 4,300 sites to approximately 8,200
sites, and included over 9,000 Web sites as of August 31, 1999. In August 1999,
we delivered over 900 million banner advertisements.

BENEFITS FOR WEB PUBLISHERS

    OUTSOURCED ADVERTISING SERVICES FOR PUBLISHERS OF SMALL- TO MEDIUM-SIZED WEB
     SITES

    Our outsourced solution provides small- to medium-sized Web sites the
technology for managing and delivering Internet advertising. Our solution allows
these sites to avoid the significant hardware, software and personnel costs
associated with building and maintaining their own ad serving technology and
sales force. In addition, small- to medium-sized Web sites on the ValueClick
network benefit from our experienced management team, our sales and marketing
organization and access to a large base of advertisers.

                                       32
<PAGE>
    ADVERTISING REVENUE OPPORTUNITIES FOR PUBLISHERS OF SMALL- TO MEDIUM-SIZED
     WEB SITES

    Advertisers paying CPM rates often impose traffic requirements that exclude
small- to medium-sized Web sites. By aggregating those sites, and providing the
built-in performance tracking of CPC, we offer a revenue opportunity for
publishers of small- to medium-sized Web sites that may not otherwise be
available. This has allowed us to develop a network of small- to medium-sized
Web sites which meet our screening standards. In addition, publishers can earn
referral commissions for introducing ValueClick to other publishers whose sites
are accepted into our network.

    INCREMENTAL ADVERTISING REVENUE FROM UNSOLD INVENTORY FOR PUBLISHERS OF
     HIGH-TRAFFIC WEB SITES

    We offer publishers of high-traffic Web sites a stream of incremental
revenue for ad space that normally would remain unsold under the CPM model. Web
publishers that attract CPM rates rarely sell their entire stock of ad
inventory. By using our CPC solution, Web publishers have an opportunity to sell
a significant portion of their unsold inventory to response-oriented advertisers
through our advertising network without jeopardizing their published rate card
structure.

BENEFITS FOR ADVERTISERS

    CPC GIVES ADVERTISERS A PERFORMANCE-BASED MODEL

    Using CPC, Internet advertisers only pay if Web users click on their
advertisements, not each time an advertisement is displayed. For Internet
advertisers trying to attract visitors who are actively looking to make a
purchase or who want to learn more about a product, CPC is a more efficient and
cost-effective choice than CPM for predicting and calculating return on
advertising investment.

    LEADING AGGREGATOR OF SMALL- TO MEDIUM-SIZED WEB SITES

    We are the leading aggregator of small- to medium-sized Web sites with over
9,000 sites currently in our network. This extensive network provides
advertisers the opportunity to place large media buys across a broad collection
of sites as well as niche targeting opportunities that have otherwise been
difficult for advertisers to reach.

    CONSUMER TRACKING DATA AFTER THE CLICK

    Our proprietary tracking management software, VisiTrak, provides real-time
marketing data regarding banner effectiveness by tracking the consumers after
they click through to our advertiser's Web site. This tool provides useful
feedback to advertisers regarding banner ad success rates, allowing them to
maximize the effectiveness of their Internet marketing strategy.

OUR STRATEGY

    Our strategy is to be the leading provider of performance-based advertising
solutions by leveraging our position as the largest aggregator of advertising
inventory of small- to medium-sized Web sites and our reputation as the
"Pay-for-Results" advertising network. Key elements of our strategy include:

    EXPAND OUR NETWORK OF WEB SITES

    We are the leading aggregator of Internet advertising inventory for small-to
medium-sized Web sites. Our highly automated proprietary software and focused
customer support allow us to manage a very large network of Web sites and a high
volume of advertising inventory. By leveraging these unique services, we expect
to continue to increase the number of small- to medium-sized Web sites in our
network and continue to attract publishers of high-traffic Web sites with
remnant inventory solutions.

<PAGE>
    GROW WITH OUR WEB PUBLISHERS

    We intend to maximize the revenue potential of every Web site on our network
by providing an opportunity to increase the quality of site content, increase
traffic to the site and by delivering new tools that generate advertising
revenue. We intend to grow with our Web publishers as their sites attract more
traffic by providing new and expanded services that position us as a one stop
advertising revenue solution.

    EXPAND OUR SALES AND MARKETING EFFORTS

    We intend to increase the size of our direct sales force and continue our
public relations and marketing efforts, including our e-mail and telemarketing
approaches. We believe that brand awareness of ValueClick and our CPC
"Pay-for-Results" solution is critical to our success, given the highly
competitive nature of the Internet advertising market.

    GROW WITH OUR WEB ADVERTISERS

    Our goal is to provide the highest quality and most cost-effective traffic
for online marketing programs. We intend to achieve this goal by working closely
with our advertisers and direct marketers to expand our services to target,
measure, optimize return on investment, and improve the quality of traffic
generated.

    We seek to increase the efficiency, effectiveness and attractiveness of our
services to advertisers through the use of technology. Our proprietary VisiTrak
software facilitates the simultaneous tracking and management of advertising
transactions, enabling advertisers to track campaigns effectively and increase
response rates. We intend to continue to improve the performance and
capabilities of VisiTrak and other technologies.

    EXTEND OUR GLOBAL PRESENCE

    We plan to aggressively continue our international expansion. ValueClick
Japan, our majority-owned subsidiary launched in March 1998, delivered over 118
million banner ads in August 1999. In the same month, we commenced operations in
London and we are planning to offer services throughout continental Europe. We
believe that the scalability of our technology and business model will allow us
to continue to successfully develop our networks in these and other
international markets.

    PROVIDE SUPERIOR CUSTOMER SERVICE

    We believe that strong customer service is vital in generating repeat
business. Therefore, we intend to continue to hire, train and support a staff of
highly skilled customer service representatives who work effectively with both
advertisers and Web publishers. We also plan to continue enhancing our service
by providing on-demand, customized online statistical information that allows
advertisers and Web publishers to rapidly assess the efficiency and performance
of Web advertisements.

PRODUCTS AND SERVICES

    We offer the following products and services for Web publishers:

    REAL-TIME STATISTICAL REPORTING

    Our proprietary Web-based tools for Web publishers provide them with
current, cumulative, historical and referral statistical information.
Information currently available includes the real-time tabulation of the current
day's click activity, relevant ratios, payment information, and amounts due.
Cumulative statistics show all-time impressions, clicks and click ratios.
Historical statistics highlight impressions and clicks in both daily and weekly
format and in either tabular or graphical format. Referral statistics detail the
amount owed the referring Web publisher.

    STREAMLINED VALUECLICK NETWORK APPLICATION PROCESS

    As part of our strategy to simplify the advertising sales process for
publishers of small- to medium-sized Web sites, we allow Web publishers to join
our network online. After completing the application, the publisher receives an
immediate response indicating our receipt of the application, and our publisher
service department then reviews the application. Once approved to join the
network, we provide the Web publisher with software to install on each Web page
where an advertisement will be placed. This process provides the publisher with
a simple, turnkey solution for entering our advertising network.

    PAYMENT MANAGEMENT

    Our publisher payment policy reduces risks to Web publishers of advertiser
bad debts and late payment carrying costs. We pay our network of publishers
monthly regardless of whether an advertiser has paid us or not. In contrast,
most other major Web advertising networks pay their publishers only upon
collection from advertisers.

    WEB SITE CATEGORIZATION CAPABILITY

    Our categorization capability enables Web publishers to maximize the value
of their advertising inventory by delivering more targeted banner advertisements
for the advertiser. This capability allows a publisher to categorize not only
its entire Web site, but also each page of its Web site.

    ABILITY TO VETO COMPETING ADVERTISER CAMPAIGN

    We provide Web publishers with the tools to exclude any competing advertiser
campaign on our network from their site.

    REFERRAL COMMISSION PROGRAM

    We provide ValueClick Web publishers the opportunity to earn commissions on
clicks generated from Web sites of publishers they introduce to the ValueClick
network through a referral. The referral program is highly automated and a
referring publisher can monitor the activity of all referred sites online
through our real-time reporting tools.

    We offer the following products and services for advertisers:

    AD SERVING SOLUTIONS

    Our proprietary system for ad serving and reporting is provided to
advertisers at no additional cost. Advertisers deliver Internet banner
advertisements to us in a form ready to be delivered on our servers. Our
proprietary software can determine how many banners are in circulation, which
banners are appropriately targeted for the consumer, and whether or not the Web
publisher has excluded any particular banners from its site. Our server then
delivers the banner to the Web publisher's site to be viewed by the consumer and
adds one impression to both the advertiser's and publisher's counter. If a user
clicks on the banner to visit the advertiser's Web site, our server registers
one click to both the advertiser's and the publisher's counter. If a user on our
network clicks on the same advertisement more than once in a six-hour period,
the click is only counted once. This feature more accurately counts the number
of "unique" users clicking on the advertiser's banner and also provides more
accurate marketing data. This entire process occurs within a matter of seconds.

    DISTRIBUTION OF ADVERTISEMENTS ON A COMPREHENSIVE OR TARGETED BASIS

    We sell advertising on our network under two major categories: Comprehensive
Network or Targeted Categories. Our sales representatives work with advertisers
to select the appropriate product based on advertisers' requirements. The
following is a more detailed description of these two products:

       Comprehensive Network: Comprehensive Network offers advertising
       placements across our entire network without specifically targeting
       individual Web sites. As the lowest-cost option offered by us, it
       provides the greatest overall reach for advertisers.

       Targeted Categories: Targeted Categories allows the advertiser to place
       ads in one or more of 15 targeted categories within our network. The use
       of these categories allows an advertiser or direct marketer to target a
       particular audience. Currently we have the following 15 targeted
       categories grouped by type of content:

<TABLE>
<S>                                <C>
- -  Automotive                      -  Games
- -  Business & Finance              -  Health & Fitness

- -  Entertainment                   -  Youth & Students
- -  Family & Lifestyles
</TABLE>

    VISITRAK

    Our proprietary VisiTrak software uses small data files residing on a
computer of a Web user, commonly known as cookies, to track users through an
advertiser's Web site. VisiTrak offers a powerful, automated solution for our
advertisers and direct marketers to enhance their Web site effectiveness. Using
VisiTrak, advertisers select the Web pages they wish to track. This feature
enables advertisers to determine the number of clicks, leads and sales each
banner has generated and allows them to tailor their Web marketing strategy
based on these results.

    ANTI-FRAUD SOLUTIONS

    Since the launch of our network we have made it a priority to detect and
investigate any fraudulent clicking activity on our advertisers' banner ads. Our
system incorporates sophisticated algorithms that detect any Web site within our
network that is receiving an abnormal click pattern during any period with the
goal of protecting advertisers from fraudulent clicking activity and improving
the accuracy of information conveyed to our advertising clients.

INTERNATIONAL OPERATIONS

    We are actively pursuing an international expansion strategy. Our current
international expansion strategy involves the sharing of the risk of the
investment with local partners while providing the partners with support,
including a license to our software, training, technical support and local
copyright and trademark licenses.

    In March 1998, we launched ValueClick Japan, a joint venture with a local
partner in Japan. Results of the joint venture have been very positive and we
believe they suggest growing acceptance of the CPC model in Japan. In August
1999, we acquired a majority interest in this joint venture, which has 14
full-time employees, of whom seven are direct salespersons and seven provide
general and administrative support. We have also commenced our operations in the
European market with

                                       36
<PAGE>
ValueClick Europe, a joint venture in London formed in August 1999. Upon the
closing of this offering, we will have the option to acquire all of the
outstanding shares of ValueClick Japan. We also have an option to acquire all of
the outstanding shares of ValueClick Europe which will become exercisable in the
future. See "Certain Transactions" on page 47.

    In addition, we are currently building a Web publisher network on a
country-by-country basis from our U.S. office. This network will provide an
operating base for establishing a local presence as each market develops and
provide for easier transition to local operations when appropriate local
partners are identified.

TECHNOLOGY PLATFORM

    Our operating infrastructure, including our network of servers, has been
designed to provide maximum performance, reliability and scalability. We
maintain high tolerance and performance objectives for banner delivery response
time from our network. To ensure that these standards are met and to facilitate
our maintenance procedures, we keep standby hardware for each component at our
data center locations. Our internal maintenance group assures quick and complete
resolution of hardware concerns.

    We currently serve advertisements from three third-party data center
facilities located in Los Angeles, California, Boca Raton, Florida and Tokyo,
Japan and we expect a new facility to come online in London before the end of
1999. Our U.S. locations also provide redundancy for each other. The entire
network is monitored both electronically and by system administrators and
escalation procedures are designed to resolve abnormalities quickly. All systems
are backed up daily and the data is stored off-site.

SALES, MARKETING AND CUSTOMER SERVICE

    We market our products and services via direct marketing, print advertising,
online advertising, the ValueClick Web site, trade show participation and other
media events. In addition, we actively pursue public relations programs to
promote our brand, products and services to potential network Web publishers and
advertisers.

    WEB PUBLISHERS

    Our highly automated, online application process is supported by a team of
nine network development and customer service professionals. Their
responsibilities include screening and marketing to prospective Web publishers,
monitoring network quality, maintaining relationships and consulting with
publishers on additional revenue opportunities.

    ADVERTISERS

    We sell our products and services to online advertisers primarily through
our direct sales force, consisting of eight sales persons as of September 30,
1999. These employees are located at our headquarters in Carpinteria,
California. We make extensive use of telemarketing and e-marketing strategies.
Sales account executives have a turnkey relationship with each of the
advertisers they service. Each account executive assists advertisers, typically
direct marketing and e-commerce companies, with all aspects of media planning
and design of their advertising campaigns. These services include advertisement
purchasing and placement, assessment of results and optimization of performance.
We intend to add additional sales personnel in the Carpinteria office and to
open additional sales offices in the U.S. over the next 12 months.

                                       37

COMPETITION

    We face intense competition in the Internet advertising market. We expect
that this competition will continue to intensify in the future as a result of
industry consolidations and the increasing number of advertising, media and
Internet companies. We compete with a diverse and large pool of advertising,
media and Internet companies.

    Our ability to compete depends upon several factors, including the
following:

    - our ability to aggregate a large network of small- to medium-sized Web
      sites efficiently,

    - the timing and market acceptance of new solutions and enhancements to
      existing solutions developed by us,

    - our customer service and support efforts,

    - our sales and marketing efforts, and

    - the ease of use, performance, price and reliability of solutions developed
      by us.

    Additional competitive factors include each competitor's reputation,
knowledge of the advertising market, financial controls, geographical coverage,
relationships with clients, technological capability and quality and breadth of
services. We expect that we will face additional competition from new entrants
into the market in the future.

    Our principal competitors are other Internet advertising network that focus
on the traditional CPM model including DoubleClick, 24/7 Media and Flycast. In
addition, we also face competition from other smaller Internet advertising
networks that also use a performance-based model, such as TeknoSurf and
ClickAgents.

    Competition for advertising placements among current and future suppliers of
Internet navigational and informational services, high-traffic Web sites and
ISPs, as well as competition with other media for advertising placements, could
result in significant price competition and reductions in advertising revenues.
In addition, as we expand the scope of our Web services, we may compete with a
greater number of Web publishers and other media companies across an increasing
range of different Web services, including in vertical markets where competitors
may have advantages in expertise, brand recognition and other areas. If existing
or future competitors develop or offer services that provide significant
performance, price, creative or other advantages over those offered by us, then
our business, result of operations and financial condition would be negatively
affected.

INTELLECTUAL PROPERTY RIGHTS

    We currently rely on a combination of common law copyright and trademark
laws, trade secret protection, confidentiality and non-disclosure agreements and
contractual provisions with our employees and with third parties to establish
and protect our proprietary rights. We have registered the trademark
"ValueClick" in the European Union and have applied to register the trademark
"ValueClick" in the United States and Japan.

    We intend to pursue the registration of our copyrights and trademarks in
other jurisdictions. We may not be able to secure copyright registration or
trademark registrations for all of our marks, in the United States or other
countries.

    Owners of other registered or unregistered copyrights, trademarks or service
marks could bring copyright or trademark infringement claims against us. If a
court of law determines that our technology infringes on the rights of other
companies, we may be required to seek licenses from third parties. However, we
may not be able to do so on commercially reasonable terms, if at all. In
addition, we may

                                       38
<PAGE>
also be subject to litigation to defend against claims of infringement of the
rights of others or to determine the scope and validity of the intellectual
property rights of others.

    If our competitors prepare and file applications in the United States that
claim trademarks used or registered by us, we may oppose those applications and
be required to participate in proceedings before the United States Patent and
Trademark Office to determine priority of rights to the trademark, which could
result in substantial costs to us.

    Actions could be brought by other third parties claiming that our products
or technology infringe patents or copyrights owned by others. In particular, the
Patent and Trademark Office recently granted a patent to DoubleClick claiming
targeting the delivery of advertisements through the Internet. The patent,
entitled "Method of Delivery, Targeting, and Measuring Advertising Over
Networks," claims the process of using linked advertising space and compiling
statistics on individual users in order to target advertisements. This patent
could limit, if not restrict, our ability to track a user's activities through
our VisiTrak software. Any litigation regarding this patent or any of our
proprietary rights could be costly and divert management's attention, result in
the loss of some of our proprietary rights, require us to seek licenses from
third parties and prevent us from selling our products and services. See "Risk
Factors--We may face costly intellectual property disputes."

EMPLOYEES

    As of September 30, 1999, we had 42 full-time and five part-time employees
in the U.S. and 14 full-time and two part-time employees in Japan. None of these
employees are covered by collective bargaining agreements. Management believes
that our relations with our employees are good.

LEGAL PROCEEDINGS

    We currently are not a party to any material litigation, nor are we aware of
any pending or threatened litigation that would have a material adverse effect
on our business, operating results or financial condition.

FACILITIES/PROPERTIES

    Our principal executive offices are located in Carpinteria, California,
where we lease two properties with approximately 9,000 and 2,750 square feet of
space, respectively. Our two leases expire on December 31, 2000 and December 31,
2002, respectively. We also lease approximately 1,490 square feet of office
space in Tokyo, Japan for ValueClick Japan. We believe that our existing leased
space in California and Japan is more than adequate for our current operations,
and that suitable replacement and additional space will be available in the
future on commercially reasonable terms.

Earle A. Malm II, Vice Chairman and Chief Marketing Officer. For information
about these officers' compensation, see "--Employment Agreements."

EMPLOYEE BENEFIT PLANS

    1999 STOCK OPTION PLAN

        In May 1999, the Board of Directors adopted and the stockholders
approved our 1999 Stock Option Plan. Under the 1999 plan, the Board, or its
designated administrators, have the flexibility to determine the type and amount
of awards to be granted to eligible participants.

    PURPOSE, STRUCTURE, AWARDS AND ELIGIBILITY.  The plan is intended to secure
for us and our stockholders the benefits arising from ownership of common stock
by individuals employed or retained by us who will be responsible for our future
growth. The plan is intended to strengthen us and our subsidiaries by attracting
and retaining competent directors, officers and employees by giving them an
incentive to contribute to our success.

        The plan administrators may grant incentive stock options or
non-statutory stock options under the 1999 plan. The options may be awarded
under the 1999 plan for any term not to exceed ten years from the date the
option is granted, except for the case of incentive stock options granted to
principal stockholders holding 10% of our outstanding common stock in which case
the term shall be no longer than five years from the date the option is granted.

        Directors, officers, and all full-time salaried employees or consultants
of us or our subsidiaries who contribute to the growth and success of the
business are eligible to be selected by the plan administrators to participate
in the 1999 plan. Our employees, including employee officers and directors, of
us or our subsidiaries may be granted either incentive stock options or
non-statutory stock options, while consultants, including non-employee officers
and directors, may only be granted non-statutory stock options.

                                       43
<PAGE>
    SHARES SUBJECT TO 1999 STOCK OPTION PLAN.  We have authorized and reserved
for issuance an aggregate of 8,000,000 shares of our common stock under the 1999
plan. The shares of common stock issuable under the 1999 plan may be authorized
but unissued shares, shares issued and reacquired by us or shares purchased by
us on the open market. If any of the awards granted under the 1999 plan expire,
terminate or are forfeited for any reason before they have been exercised,
vested or issued in full, the unused shares subject to those expired, terminated
or forfeited awards will again be available for purposes of the 1999 plan.

    EFFECTIVE DATE AND DURATION.  The 1999 plan became effective upon its
adoption by the Board of Directors in May 1999. The plan will continue in effect
for ten years from the date of its adoption unless sooner terminated by the
Board of Directors. In the event of a merger or consolidation in which
ValueClick is not the surviving corporation, and such surviving corporation
refuses to assume a substitute option as provided in the plan, such options
shall become fully exercisable for a period of 15 days of the date of notice
from the Board.

    ADMINISTRATION.  The 1999 plan is administered by the full Board of
Directors or at the discretion of the Board by a Stock Option Committee
appointed by the Board. The Stock Option Committee shall consist of no less than
two members of the Board who are:

    - non-employee directors within the meaning of the Rule 16b-3 promulgated
      under the Securities Exchange Act of 1934, so long as non-employee
      director administration is required under Rule 16b-3; and

    - outside directors as defined in section 162(m) of the Internal Revenue
      Code of 1986, so long as outside directors are required by the Code.

    Subject to the above limitations, the Board of Directors may from time to
time remove members from the committee and fill all vacancies on the committee,
however caused. The program administrators may hold meetings when and where they
determine, will keep minutes of their meetings, and may interpret, prescribe,
amend, and rescind rules and regulations in accordance with the terms of the
1999 plan.

    401(K) RETIREMENT PLAN

    We adopted an amended 401(k) defined contribution retirement plan in May
1999 which became effective in July 1999. The plan covers all full-time
employees. Employees become eligible to participate in the plan after they have
worked for a three-consecutive month period, commencing on the date of hire, and
for which the employee is credited with at least 1,000 paid hours, including
vacation, sickness, disability, leave of absence and back pay. The plan provides
for voluntary employee contributions up to 20% of annual compensation, subject
to the maximum limit allowed by the Internal Revenue Service guidelines, which
is currently $10,000 annually. We may make matching contributions to each
participating employee based on his or her voluntary contributions to the plan.
We may also make discretionary contributions to the plan at our sole discretion.
As of September 30, 1999 we have contributed approximately $14,000 to the plan.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

    We have included in our Certificate of Incorporation a provision indicating
that, to the extent permitted by Delaware General Corporation Law, our directors
will not be personally liable to us or our stockholders for monetary damages for
breach of fiduciary duty as directors, except for liability:

    - for any breach of the director's duty of loyalty to us or our
      stockholders;

    - for acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law;

                                       44
<PAGE>
    - under Section 174 of the General Corporation Law of the State of Delaware;
      or

    - for any transaction from which the director derived an improper personal
      benefit.

    Our Bylaws provide for the indemnification of our directors and executive
officers to the fullest extent permitted by the Delaware General Corporation
Law. We may limit the extent of such indemnification by individual contracts
with our directors and executive officers, but have not done so. We are not,
however, required to indemnify any director or executive officer in connection
with any proceeding initiated by such person or any proceeding by such person
against us or our directors, officers, employees or other agents unless such
indemnification is expressly required to be made by law, the proceeding was
authorized by our Board of Directors or such indemnification is provided by us,
in our sole discretion, pursuant to the powers vested in us under the Delaware
General Corporation Law. We are required to advance, prior to the final
disposition of any proceeding, promptly on request, all expenses incurred by any
director or executive officer in connection with such proceeding on receipt of
an undertaking by or on behalf of such person to repay those amounts if it
should be determined ultimately that he or she is not entitled to be indemnified
under our Bylaws or otherwise.

    We have entered into indemnification agreements with our directors and some
of our officers. These agreements contain provisions that may require us, among
other things, to indemnify these directors and officers against certain
liabilities that may arise because of their status or service as directors or
officers, except for liabilities arising from willful misconduct of a culpable
nature, advance their expenses incurred as a result of any proceeding against
them as to which they could be indemnified, and obtain directors' and officers'
liability insurance if it is maintained for other directors or officers.

    At present, we are not aware of any pending or threatened litigation or
proceeding involving a director, officer, employee or agent in which
indemnification would be required or permitted. We are not aware of any
threatened litigation or proceeding that might result in a claim for
indemnification. We believe that our charter provisions and indemnification
agreements are necessary to attract and retain qualified persons as directors
and officers.

EMPLOYMENT AGREEMENTS

    We have entered into employment agreements with each of Messrs. Zarley,
Schwenk, Johnson and Malm.

    In January 1999, we entered into an at-will employment agreement with Mr.
Zarley. Under this agreement, Mr. Zarley is entitled to a base salary of
$150,000 per year. This agreement may be terminated at any time by either party
upon ten days notice. In connection with this agreement, we granted Mr. Zarley
options to purchase 1,200,000 shares of our common stock at an exercise price of
$0.13 per share under our 1999 Stock Option Plan. 150,000 options became
exercisable in July 1999. The remaining 1,050,000 options shall become
exercisable in equal monthly installments over the 18 month period thereafter.
All 1,200,000 options shall be immediately exercisable upon the closing of our
initial public offering or upon transfer of 50% or more of the ownership
interest of ValueClick.

    In April 1999, we entered into an at-will employment agreement with Mr.
Schwenk. Under this agreement, Mr. Schwenk is entitled to a base salary of
$100,000 per year. This agreement may be terminated at any time by either party
upon ten days notice. In connection with this agreement, we granted Mr. Schwenk
options to purchase 400,000 shares of our common stock at an exercise price of
$0.13 per share under our 1999 Stock Option Plan. 50,000 options became
exercisable in October 1999. The remaining 350,000 options will become
exercisable in equal monthly installments over the 42 month period thereafter.
200,000 options shall be immediately exercisable upon the closing of our initial
public offering or upon transfer of 50% or more of the ownership interest of
ValueClick.

                                       45
<PAGE>
    In May 1999, we entered into an at-will employment agreement with Mr.
Johnson. Under this agreement, Mr. Johnson is entitled to a base salary of
$130,000 per year. Upon the closing of our initial public offering or a change
in 50% or more of ownership Mr. Johnson will be entitled to a $20,000 bonus. If
we terminate Mr. Johnson's employment in connection with or following, and by
reason of the transfer of ownership of 50% or more of ValueClick, Mr. Johnson
will be entitled to severance equal to one year's salary. This agreement may be
terminated at any time by either party upon ten days notice. In connection with
this agreement, we granted Mr. Johnson options to purchase 300,000 shares of our
common stock at an exercise price of $0.50 per share under our 1999 Stock Option
Plan. 37,500 options will become exercisable in November 1999. The remaining
262,500 options will become exercisable in equal monthly installments over the
42 month period thereafter. 150,000 options shall be immediately exercisable
upon the closing of our initial public offering or upon transfer of 50% or more
of the ownership interest of ValueClick.

    In June 1999, we entered into an at-will employment agreement with Mr. Malm.
Under this agreement, Mr. Malm is entitled to a base salary of $150,000 per
year. This agreement provides for a one-year term but may be terminated at any
time by either party upon ten days notice. In the event we terminate Mr. Malm's
employment following a change in control of ValueClick or for any reason other
than for cause, Mr. Malm will be entitled to all compensation, stock options and
health and welfare benefits to which he would otherwise be entitled during the
remaining term of employment. In connection with this agreement, we granted Mr.
Malm options to purchase 800,000 shares of our common stock at an exercise price
of $0.50 per share under our 1999 Stock Option Plan. 800,000 options will vest
in 12 equal monthly installments over the 12 month period commencing on June 1,
1999. These 800,000 options will become immediately exercisable upon the closing
of our initial public offering or upon transfer of 50% or more of the ownership
interest of ValueClick.

                              CERTAIN TRANSACTIONS

    On May 1, 1998, Brian Coryat, the sole stockholder of Web-Ignite
Corporation, caused Web-Ignite to transfer to ValueClick, LLC its rights to (a)
the ValueClick trademarks and domain names, (b) the trademark license, software
license and copyright agreement with Trans-Pacific Ltd., predecessor to
ValueClick Japan, and (c) the rights to the advertising delivery software used
in our business. At that time, Michael Bueno, the primary developer of the
software, transferred all of his remaining royalty and ownership rights in the
software to ValueClick, LLC. In exchange, on May 1, 1998, ValueClick, LLC issued
a 77% membership interest to Mr. Coryat, a 15% membership interest to Mr. Bueno,
and a 0.5% membership interest to Web-Ignite Corporation. Web-Ignite
subsequently transferred its 0.5% membership interest to Brian Coryat. Upon the
reorganization of ValueClick, LLC as ValueClick, Inc., Mr. Coryat's entire
membership interest in ValueClick, LLC was exchanged for 15,253,560 shares of
our common stock and 24,761 shares of our Series A Convertible Preferred Stock
and Mr. Bueno's membership interest in ValueClick, LLC was exchanged for
2,971,316 shares of our common stock. Mr. Coryat was the sole stockholder and
sole director of Web-Ignite, and was President and Chief Executive Officer and a
director of ValueClick, LLC. Mr. Coryat is a director, and is President and
Chief Operating Officer of ValueClick, Inc. Mr. Bueno served as a director and
as Chief Technical Officer of ValueClick, LLC and was Vice President, Chief
Technology Officer and a director of ValueClick, Inc. Mr. Bueno resigned as a
director of ValueClick, Inc. as of September 30, 1999 and is no longer an
officer of ValueClick, Inc. Mr. Coryat and Mr. Bueno each currently holds more
than 5% of our stock.

    ValueClick was formed as a California limited liability company, ValueClick,
LLC, on May 1, 1998. On December 31, 1998, ValueClick, LLC was reorganized as
ValueClick, Inc., a Delaware corporation. In connection with this
reorganization, ValueClick, Inc. acquired all of the assets and assumed all of
the liabilities of ValueClick, LLC. It also issued to ValueClick, LLC,
19,952,024 shares of its common stock, 297,132 shares of its Series A
Convertible Preferred Stock and 1,047,804 shares of its Series B Convertible
Preferred Stock, all of which ValueClick, LLC then distributed to its members
upon its dissolution.

    In June 1998, Brian Coryat borrowed $50,000, at an interest rate of 9% per
annum, from ValueClick, LLC. Mr. Coryat repaid this loan in full in December
1998. Mr. Coryat served as President and Chief Executive Officer and was a
director of ValueClick, LLC.

    On December 31, 1998, we borrowed $200,000, at an interest rate of 10% per
annum, from Brian Coryat, a director, and our President and Chief Operating
Officer. We repaid this loan in full in January 1999.

    VALUECLICK EUROPE

    In August 1999, we formed a joint venture with three of our directors to
engage in the Internet advertising business in the United Kingdom and Europe by
purchasing a 20% interest in ValueClick Europe, Limited, a corporation organized
under the laws of the U.K., for $99,000. At that time, we granted ValueClick
Europe an exclusive license to our trademarks and other intellectual property
within western Europe, Scandinavia and the U.K., which may become non-exclusive
if ValueClick Europe fails to recognize a minimum level of gross revenues during
the 12 months ending August 2000. We co-founded ValueClick Europe with Mr.
Umberger, one of our directors; Mr. Coryat, our President, Chief Operating
Officer and director; Mr. Zarley, our Chairman of the Board and Chief Executive
Officer; and another party. Mr. Umberger currently owns 45,000 shares, or 45%,
of ValueClick Europe, and Messrs. Coryat and Zarley each own 2,500 shares, or
2.5%.

    We have an option to acquire all of the outstanding shares of ValueClick
Europe which will become exercisable in the future. The option exercise price
per share is calculated by dividing a numerator, which may vary, by a
denominator equal to the number of outstanding shares of ValueClick

                                       47
<PAGE>
Europe common stock. The numerator used to calculate the option exercise price
equals (a) four times ValueClick Europe's gross revenues for the three calendar
months preceding the option exercise, which we refer to as ValueClick Europe's
annualized gross revenues, multiplied by (b) five. We refer to the option
exercise price arrived at using this numerator as the base option exercise
price. The base option exercise price is subject to adjustment, however, in the
event we consummate an initial public offering, or IPO, of our stock, or in the
event of a change of control of ValueClick, Inc.

    In the event of an IPO, and if adjustment would result in a lower option
exercise price than the base option exercise price, the numerator used to
determine the option exercise price will equal (a)(1) the product of the average
price per share of our common stock for the three months immediately preceding
exercise of the option and the total number of shares of our common stock on the
date of the option exercise, divided by (2) four times our gross revenues for
the three calendar months preceding the option exercise, which we refer to as
our annualized gross revenues, multiplied by (b) ValueClick Europe's annualized
gross revenues, multiplied by (c) 0.75.

    In the event of a change of control of ValueClick, Inc., prior to or after
an IPO, and if adjustment would result in a lower option exercise price than the
base option exercise price, the numerator used to calculate the option exercise
price will also be adjusted. In the event a change of control results from an
acquisition by a privately-held company or by a company not in a substantially
similar business, the numerator used to calculate the option exercise price will
be equal to (a)(1) the fair market value of ValueClick, Inc. based on the
consideration paid in the change of control transaction divided by (2) our
annualized gross revenues, multiplied by (b) 0.75, multiplied by (c) ValueClick
Europe's annualized gross revenues. In the event a change of control results
from an acquisition by a publicly traded company in a substantially similar
business, the numerator used to calculate the option exercise price will be
equal to (1)(a) the average share price of the acquiring company for the three
months immediately preceding the date of the acquisition multiplied by the total
number of shares of stock of the acquiring company outstanding on the date of
the acquisition (b) divided by four times the acquiring company's gross revenues
for the three calendar months preceding the acquisition date, multiplied by (2)
0.75, multiplied by (3) ValueClick Europe's annualized gross revenues.

                       PRINCIPAL AND SELLING STOCKHOLDERS

    The following table sets forth information regarding the beneficial
ownership of our common stock as of September 30, 1999, as adjusted to reflect
the sale of common stock in this offering and the automatic conversion of all
shares of preferred stock to common stock upon the consummation of this
offering, for each of the following persons:

    - each of our directors and each of the named officers in the
      "Management--Executive Compensation" section of this prospectus;

    - all directors and executive officers as a group; and

    - each person who is known by us to own beneficially five percent or more of
      our common stock prior to this offering.

    Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. In computing the number of shares
beneficially owned by a person and the percentage of ownership of that person,
shares of common stock subject to options held by that person that are currently
exercisable or become exercisable within 60 days of September 30, 1999 are
included. Those shares, however, are not deemed outstanding for the purpose of
computing the percentage ownership of any other person. Unless otherwise
indicated in the table, the persons and entities named in the table have sole
voting and sole investment power with respect to the shares set forth opposite
the stockholder's name. Except as specified, all share number and percentages
assume no exercise of the underwriters' over-allotment option.

                          DESCRIPTION OF CAPITAL STOCK

    Upon the completion of this offering, we will be authorized to issue
100,000,000 shares of common stock, $.001 par value per share, and 20,000,000
shares of preferred stock, $.001 par value per share.

COMMON STOCK

    As of September 30, 1999, there were 20,478,008 shares of common stock
outstanding held of record by 16 stockholders (or 31,065,152 shares, held of
record by 47 stockholders as adjusted to reflect the conversion of all
outstanding preferred stock upon the consummation of this offering). Options to
purchase an aggregate of 5,489,200 shares of common stock were also outstanding
as of September 30, 1999. There will be          shares of common stock
outstanding (assuming no exercise of the underwriters' over-allotment option or
exercise of outstanding options under our 1999 stock option plan after September
30, 1999) after giving effect to the sale of the shares offered hereby.

    The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. Subject to
preferences that may be applicable to any outstanding preferred stock, holders
of common stock are entitled to receive ratably such dividends as may be
declared by the board out of funds legally available for that purpose. See
"Dividend Policy." In the event of liquidation, dissolution or winding up of
ValueClick, the holders of common stock are entitled to share ratably in all
assets remaining after payment of liabilities, subject to the prior distribution
rights of any outstanding preferred stock. The common stock has no preemptive or
conversion rights or other subscription rights. The outstanding shares of common
stock are, and the shares of common stock to be issued upon completion of this
offering will be, fully paid and non-assessable.

PREFERRED STOCK

    The Board will have the authority, without further action by the
stockholders, to issue up to 20,000,000 shares of preferred stock, $.001 par
value, in one or more series. The Board will also have the authority to
designate the rights, preferences, privileges and restrictions of each such
series, including dividend rights, dividend rates, conversion rights, voting
rights, terms of redemption, redemption prices, liquidation preferences and the
number of shares constituting any series.

    The issuance of preferred stock might have the effect of delaying, deferring
or preventing a change in control of ValueClick without further action by the
stockholders. The issuance of preferred stock with voting and conversion rights
might also adversely affect the voting power of the holders of common stock. In
certain circumstances, an issuance of preferred stock could have the effect of
decreasing the market price of the common stock. As of the closing of this
offering, no shares of preferred stock will be outstanding. We currently have no
plans to issue any shares of preferred stock.

    The Board has authorized the issuance of three series of preferred stock--
Series A, B and C convertible preferred stock. There are 297,132 authorized,
issued and outstanding shares of Series A, 1,047,804 authorized, issued and
outstanding shares of Series B and 1,400,000 shares of Series C authorized, of
which 1,301,850 are issued and outstanding. Upon consummation of this offering,
the 297,132 shares of Series A, 1,047,804 shares of Series B, and 1,301,850
shares of Series C will be converted into 1,188,528, 4,191,216, and 5,207,400
shares of common stock, respectively, or an aggregate of 10,587,144 shares of
common stock.

AUTHORIZED BUT UNISSUED CAPITAL STOCK

    We estimate that following the completion of this offering we will have
approximately          shares of authorized but unissued common stock, including
an aggregate of 8,000,000 shares reserved for issuance upon the exercise of
options under our 1999 stock plan, and 20,000,000 shares of authorized preferred
stock, of which none will be issued and outstanding. If the underwriters' over-

                                       51
<PAGE>
allotment option is exercised in full, we will have approximately         shares
of authorized but unissued common stock. Delaware law does not require
stockholder approval for the issuance of authorized shares. However, the listing
requirements of the Nasdaq National Market, which apply so long as the common
stock remains included in that inter-dealer quotation system, require prior
stockholder approval of specified issuances, including issuances of shares
bearing voting power equal to or exceeding 20% of the pre-issuance outstanding
voting power or pre-issuance outstanding number of shares of common stock. These
additional shares could be used for a variety of corporate purposes, including
future public offerings to raise additional capital or to facilitate corporate
acquisitions. We currently do not have any plans to issue additional shares of
common stock or preferred stock, other than in connection with employee
compensation plans. See "Management--Stock Plans/Employee Compensation
Programs." One of the effects of the existence of unissued and unreserved common
stock and preferred stock may be to enable the Board to issue shares to persons
who may agree or be inclined to vote in concert with current management on
issues put to consideration of stockholders, which issuance could render more
difficult or discourage an attempt to obtain control of us by means of a merger,
tender offer, proxy contest or otherwise, and protect the continuity of our
management and possibly deprive the stockholders of the opportunity to sell
their shares of common stock at prices higher than prevailing market prices.

DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS

    Certain provisions of Delaware law and our charter documents could make the
acquisition of ValueClick and the removal of incumbent officers and directors
more difficult. These provisions are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
persons seeking to acquire control of ValueClick to negotiate with it first. We
believe that the benefits of increased protection of our potential ability to
negotiate with the proponent of an unfriendly or unsolicited proposal to acquire
or restructure ValueClick outweigh the disadvantages of discouraging such
proposals because, among other things, negotiation of such proposals could
result in an improvement of their terms.

    We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. In general, this statute prohibits a publicly-held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date that the person became
an interested stockholder unless (with certain exceptions) the business
combination or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. Generally, a "business
combination" includes a merger, asset or stock sale, or other transaction
resulting in a financial benefit to the stockholder. Generally, an "interested
stockholder" is a person who, together with affiliates and associates, owns (or
within three years prior, did own) 15% or more of the corporation's voting
stock. These provisions may have the effect of delaying, deferring or preventing
a change in control of us without further action by our stockholders.

    Our Certificate of Incorporation provides that stockholder action can be
taken at an annual or special meeting of stockholders and may be taken by
written consent. Our Bylaws provide that special meetings of stockholders can be
called by the president, the Board or by a majority of the stockholders.
Moreover, the business permitted to be conducted at any special meeting of
stockholders is limited to the business brought before the meeting by the Board,
the President or any such stockholder. Our Bylaws set forth an advance notice
procedure with regard to the nomination, other than by or at the direction of
the Board, of candidates for election as directors and with regard to business
to be brought before a meeting of stockholders.

TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for the common stock is ChaseMellon
Shareholder Services, L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Prior to this offering, there has been no market for our common stock.
Future sales of substantial amounts of common stock in the public market could
adversely affect prevailing market prices. Furthermore, since only a limited
number of shares will be available for sale shortly after this offering because
of certain contractual and legal restrictions on resale (as 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          shares
of common stock. Of these shares, the          shares sold in the offering (plus
any shares issued upon exercise of the underwriters' over-allotment option) will
be freely tradable without restriction under the Securities Act, unless
purchased by our "affiliates" as that term is defined in Rule 144 under the
Securities Act (generally, officers, directors or 10% stockholders).

    The remaining 31,065,152 shares outstanding are "restricted securities"
within the meaning of Rule 144 under the Securities Act. Restricted securities
may be sold in the public market only if registered or if they qualify for an
exemption from registration under Rules 144, 144(k) or 701 promulgated under the
Securities Act, which are summarized below. Sales of the restricted securities
in the public market, or the availability of such shares for sale, could
adversely affect the market price of the common stock.

    Our stockholders and our option holders have entered into lock-up agreements
generally providing that they will not offer, sell, contract to sell or grant
any option to purchase or otherwise dispose of our common stock or any
securities exercisable for or convertible into our common stock owned by them
for a period of 180 days after the date of this prospectus without the prior
written consent of Volpe Brown Whelan & Company, LLC on behalf of the
underwriters. As a result of these contractual restrictions, notwithstanding
possible earlier eligibility for sale under the provisions of Rules 144, 144(k)
and 701, shares subject to lock-up agreements may not be sold until such
agreements expire or are waived by the designated underwriters' representative.
Taking into account the lock-up agreements, and assuming Volpe Brown Whelan &
Company does not release stockholders from these agreements, the following
shares will be eligible for sale in the public market at the following times:

    - Beginning on the effective date of the offering, only the shares sold in
      the offering will be immediately available for sale in the public market;

    - Beginning 180 days after the effective date of the offering, 29,432,152
      shares will be eligible for sale pursuant to Rules 144, 144(k) and 701;
      and

    - An additional 1,633,000 shares will become eligible for sale pursuant to
      Rule 144 beginning on June 23, 2000. Shares eligible to be sold by
      affiliates pursuant to Rule 144 are subject to volume restrictions as
      described below.

    In general, under Rule 144 as currently in effect, and beginning after the
expiration of the lock-up agreements (180 days after the date of this
prospectus), a person (or persons whose shares are aggregated) who has
beneficially owned restricted securities for at least one year would be entitled
to sell within any three-month period a number of shares that does not exceed
the greater of: one percent of the number of shares of common stock then
outstanding (which will equal approximately          shares immediately after
the offering) or the average weekly trading volume of the common stock during
the four calendar weeks preceding the sale. Sales under Rule 144 are also
subject to certain manner of sale provisions and notice requirements and to the
availability of current public information about us. Under Rule 144(k), a person
who is not deemed to have been our affiliate at any time during the three months
preceding a sale, and who has beneficially owned the shares proposed to be sold
for at least two years, is entitled to sell such shares without complying with
the manner of sale, public information, volume limitation or notice provisions
of Rule 144.

                                       53
<PAGE>
    Beginning 90 days after the effective date of the registration statement for
this offering, any employee, officer or director of or consultant to us who
purchased shares pursuant to a written compensatory plan or contract may be
entitled to rely on the resale provisions of Rule 701. Rule 701 permits
affiliates to sell their Rule 701 shares under Rule 144 without complying with
the holding period requirements of Rule 144. Rule 701 further provides that
non-affiliates may sell such shares in reliance on Rule 144 without having to
comply with the holding period, public information, volume limitation or notice
provisions of Rule 144. In addition, we intend to file registration statements
under the Securities Act as promptly as possible after the effective date to
register shares to be issued pursuant to our employee benefit plans. As a
result, any options exercised under the 1999 Stock Option Plan, as amended, or
any other benefit plan after the effectiveness of such registration statement
will also be freely tradable in the public market, except that shares held by
affiliates will still be subject to the volume limitation, manner of sale,
notice and public information requirements of Rule 144 unless otherwise
resalable under Rule 701. As of September 30, 1999, there were outstanding
options under the 1999 Stock Option Plan for the purchase of 5,489,200 shares.
See "Risk Factors--virtually all of our shares will be eligible for sale shortly
after this offering, which could result in a decline in our stock price" and
"Management--Employee Benefit Plans."

among the underwriters and us, each of the underwriters named below, for whom
Volpe Brown Whelan & Company, LLC, William Blair & Company, L.L.C., Prudential
Securities Incorporated and PrudentialSecurities.com are acting as
representatives, has severally agreed to purchase from us the aggregate number
of shares of our common stock set forth opposite its name below:

    The underwriting agreement provides that the obligations of the underwriters
to purchase shares of common stock are subject to approval of some matters by
their counsel and to various other conditions. Under the terms and conditions of
the underwriting agreement, all of the underwriters are obligated to take and
pay for all such shares of common stock if any are taken.

    The following table shows the per share and total underwriting discounts and

    We estimate that the total expenses of this offering, excluding underwriting
discounts and commissions, will be    million.

    The underwriters propose initially to offer the shares of common stock
directly to the public at the public offering price set forth on the cover page
of this prospectus and to some dealers at the same price, less a concession not
in excess of $         per share. The underwriters may allow, and those dealers
may reallow, concessions not in excess of $         per share of common stock to
other dealers. After the initial public offering of the common stock, the
offering price of the common stock and other selling terms may be changed by the
underwriters.

    Pursuant to the underwriting agreement, we and certain selling stockholders
have granted the underwriters an option, exercisable for 30 days from the date
of this prospectus, to purchase up to additional shares of common stock from us
and up to an additional 250,000 shares of common stock from the selling
stockholders on the same terms as set forth on the cover page of this
prospectus. The underwriters may exercise this option solely to cover
over-allotments. To the extent the option is exercised, each underwriter will
have a commitment, subject to certain conditions, to purchase a number of
additional shares of common stock proportionate to the underwriter's initial
commitment pursuant to the underwriting agreement.

    Our directors and officers and substantially all of our stockholders and
option holders have agreed that they will not sell, directly or indirectly, any
shares of common stock without the prior written consent of Volpe Brown Whelan &
Company on behalf of the underwriters for a period of 180 days from the date of
this prospectus. All remaining option holders have agreed with us that they will
not sell, directly or indirectly, shares of common stock issued upon exercise of
their options for a period of 180 days from the effective date of the
registration statement. In addition, we have agreed that for a period of 180
days after the date of this prospectus we will not, without the prior written
consent of

                                       55
<PAGE>
Volpe Brown Whelan & Company, LLC on behalf of the underwriters, offer, sell or
otherwise dispose of any shares of common stock except for the shares of common
stock offered by this prospectus and the shares issued and options granted
pursuant to our stock option plan.

    Prior to this offering, there has been no public market for our common
stock. Consequently, the initial offering price for the common stock will be
determined by agreement between us and the representatives of the underwriters.
Among the factors to be considered in making this determination will be the
history of, and the prospects for, the industry in which we compete, an
assessment of our management, our present operations, our historical results of
operations and the trend of our revenues and earnings, our prospects for future
earnings, the general condition of the securities markets at the time of this
offering and the price of similar securities of generally comparable companies.
We cannot assure you that an active trading market will develop for our common
stock or that our common stock will trade in the public markets at or above the
initial public offering price.

    In order to facilitate this offering, persons participating in this offering
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock during and after this offering, including
over-allotment, stabilizing and short-covering transactions and the impositions
of penalty bids. Specifically, the underwriters may over-allot or otherwise
create a short position in the common stock for their own account by selling
more shares of common stock than have been sold to them by us. The underwriters
may elect to cover this short position by purchasing shares of common stock in
the open market or by exercising the over-allotment option granted to the
underwriters. In addition, the underwriters may stabilize or maintain the price
of the common stock by bidding for or purchasing shares of common stock in the
open market and may impose penalty bids, under which selling concessions allowed
to syndicate members or other broker-dealers participating in this offering are
reclaimed if shares of common stock previously distributed in this offering are
repurchased in connection with stabilization transactions or otherwise. The
effect of these transactions may be to stabilize or maintain the market price at
a level above that which might otherwise prevail in the open market. The
imposition of a penalty bid may also affect the price of the common stock to the
extent that it discourages resales. No representation is made as to the
magnitude or effect of this stabilization or other transactions. These
transactions may be effected on the Nasdaq National Market or otherwise and, if
commenced, may be discontinued at any time.

    We and the selling stockholders have agreed to indemnify the underwriters
against certain liabilities, losses and expenses, including liabilities under
the Securities Act, or to contribute to payments that the underwriters may be
required to make in respect thereof.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
ValueClick, Inc.

    In our opinion, the accompanying balance sheet and the related statements of
operations, stockholders' equity and cash flows present fairly, in all material
respects, the financial position of ValueClick, Inc. (the "Company") at December
31, 1998, and the results of its operations and its cash flows for the period
from May 1, 1998 (inception) through December 31, 1998, in conformity with
generally accepted accounting principles. 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
of these financial statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for the opinion expressed above.

          (ALL INFORMATION WITH RESPECT TO JUNE 30, 1999 IS UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BASIS OF PRESENTATION

    ValueClick, Inc. ("ValueClick" or the "Company") commenced operations as
ValueClick, LLC, a California limited liability company, on May 1, 1998
(inception). Prior to the formation of ValueClick, LLC, the ValueClick Internet
advertising delivery business began in July 1997 as a line of business within
Web-Ignite Corporation, an S-corporation wholly owned by the founding member of
ValueClick, LLC. The reorganization and formation of ValueClick, LLC was
accounted for as a transaction by entities under common control and was effected
by the founding member causing Web-Ignite to transfer the rights to the
ValueClick trademarks, domain names, the trademark, license, software license
and copyright agreements with Trans-Pacific Ltd., predecessor to ValueClick
Japan, and the rights to the advertising delivery software used in the business
to ValueClick, LLC. On December 31, 1998, ValueClick, LLC completed its
conversion and reincorporation from a California LLC to a Delaware C-corporation
by completing a merger with ValueClick, Inc., a Delaware C-corporation formed by
ValueClick, LLC. The accompanying financial statements reflect the conversion
and reincorporation.

    The Company is an Internet based advertising network that provides a
performance based advertising solution on a cost-per-click basis to advertisers
and e-commerce companies.

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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates.

CASH AND CASH EQUIVALENT

    The Company considers all short-term investments with an original maturity
at date of purchase of three months or less to be cash equivalents. At December
31, 1998, cash equivalents consist of money market funds.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Depreciation on property and
equipment is calculated on the straight-line method over the estimated useful
lives of the assets ranging from 3 to 5 years. Leasehold improvements are
amortized over their estimated useful lives, or the term of the lease, whichever
is shorter.

REVENUE RECOGNITION

    The Company's revenues are principally derived from the delivery of
advertising click-throughs through third-party Web sites comprising the
ValueClick Network (the "Network"). Revenue is recognized in the period that the
advertising click-throughs occur, provided that no significant Company
obligations remain and collection of the resulting receivable is probable. To
date, the Company's agreements have not required guaranteed minimum
click-throughs.

    The Company becomes obligated to make payments to third-party Web sites,
which have contracted with the Company to be part of the Network, in the period
the advertising click-throughs

    (ALL INFORMATION WITH RESPECT TO JUNE 30, 1999 IS UNAUDITED) (CONTINUED)

are delivered. Such expenses are classified as cost of revenues in the
accompanying statements of operations

    Deferred revenue represents payments received in advance for advertising
click-throughs. Such fees will be recognized as revenues once the advertising
click-throughs are delivered and no significant Company obligations remain.

COST OF REVENUES

    Cost of revenues consist of payments to third-party web sites in the
Company's network, telecommunications costs, depreciation of equipment used for
ad delivery, and personnel and occupancy costs related to the Company's ad
delivery infrastructure.

SALES AND MARKETING

    Sales and marketing expenses include salaries, sales commissions, employee
benefits, travel and related expenses for the Company's sales force, and
advertising costs.

    Advertising costs included in sales and marketing expenses totaled $317,998
and $181,634 for the year ended December 31, 1998 and six months ended June 30,
1999.

GENERAL AND ADMINISTRATIVE

    General and administrative expenses include salaries, related benefits and
expenses for the executive, finance, legal and human resources personnel, and
other general overhead costs.

TECHNOLOGY ENHANCEMENTS

    Technology development costs and enhancements to existing products are
charged to operations as incurred. Software development costs are required to be
capitalized when a product's technological feasibility has been established by
completion of a working model of the product and ending when a product is
available for general release to customers. To date, completion of a working
model of the Company's products and general releases have substantially
coincided. As a result, the Company has not capitalized any software development
costs since such costs have not been significant.

STOCK-BASED COMPENSATION

    The Company accounts for its employee stock option plan in accordance with
the provisions of Accounting Principles Board ("APB") Opinion No. 25,
"Accounting for Stock Issued to Employees" and related interpretations.
Accordingly, compensation expense related to employee stock options is recorded
only if, on the date of the grant, the fair value of the underlying stock
exceeds the exercise price. The Company adopted the disclosure-only requirements
of Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation" ("Statement No. 123"), which allows entities to
continue to apply the provisions of APB Opinion No. 25 for transactions with
employees and provide pro forma net income and pro forma earnings per share
disclosures for employee stock grants made in 1999 and future years as if the
fair-value based method of accounting in Statement No. 123 had been applied to
these transactions.

FOREIGN CURRENCY TRANSLATION

    The Company's equity investment in ValueClick Japan subjects it to foreign
currency exchange risks as ValueClick Japan denominates its transactions in the
Japanese Yen. The Company's exposure is

limited to the extent of the equity investment in ValueClick Japan which
represents 7.5% and 5.5% of its total assets at December 31, 1998 and June 30,
1999, respectively. Foreign currency impacts for the Investment in ValueClick
Japan were not significant at December 31, 1998 and June 30, 1999.

CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Company to concentration
of credit risk consist of cash and cash equivalents and accounts receivable.
Cash and cash equivalents are deposited with major financial institutions; at
times, such balances with any one financial institution may be in excess of FDIC
insurance limits. Credit is extended to customers based on an evaluation of
their financial condition. The Company generally does not require collateral or
other security to support accounts receivable. The Company performs ongoing
credit evaluations of its customers and maintains an allowance for potential bad
debt. To date such losses, if any, have been within management's expectations.
At December 31, 1998, one customer comprised 20% of the accounts receivable
balance. For the year ended December 31, 1998, one customer comprised 43% of
revenues. At June 30, 1999, no customer comprised greater than 10% of revenues.
At June 30, 1999, two customers comprised 18% and 13% of the accounts receivable
balance, respectively.

FINANCIAL INSTRUMENTS

    The Company's financial instruments, including cash and cash equivalents,
accounts receivable, accounts payable and short-term debt, are carried at
historical cost. At December 31, 1998, the fair values of these instruments
approximated their financial statement carrying amounts because of the
short-term maturity of these instruments and the relative stable interest rate
environment.

IMPAIRMENT OF LONG-LIVED ASSETS

    The Company evaluates its long-lived assets for impairment whenever events
or changes in circumstances indicate that the carrying amount of such assets or
intangibles may not be recoverable. Recoverability of assets to be held and used
is measured by a comparison of the carrying amount of an asset to future
undiscounted net cash flows expected to be generated by the asset. If such
assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets exceeds the
fair value of the assets. To date, no such impairment has been recorded.

BASIC AND DILUTED NET LOSS PER SHARE

    The Company has adopted the provisions of Financial Accounting Standards
Board ("FASB") issued SFAS No. 128, "Earnings Per Share" ("Statement 128").
Basic and diluted net loss per share is computed by dividing the net loss per
share by the weighted average shares of common stock outstanding.

UNAUDITED PRO FORMA NET LOSS PER SHARE

    Unaudited pro forma net loss per share is computed by dividing net loss by
the sum of the weighted average number of shares of common stock outstanding,
including the shares resulting from the conversion of the convertible preferred
stock as though such conversion occurred at December 31, 1998 and June 30, 1999.
Each share of preferred stock converts into four shares of common stock. The
conversion of the

events had occurred on June 30, 1999.

COMPREHENSIVE INCOME

    The Company has adopted the provisions of SFAS No. 130, "Reporting
Comprehensive Income" ("Statement No. 130"). Statement No. 130 establishes
standards for reporting comprehensive income and its components in financial
statements. Comprehensive income, as defined, includes all changes in equity
(net assets) during a period from non-owner sources. To date, the Company has
not had any transactions that are required to be reported in comprehensive
income.

SEGMENTS

    The Company adopted the provisions of SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information" ("Statement No. 131").
Statement No. 131 which establishes standards for the way companies report
information about operating segments in annual financial statements. It also
establishes standards for related disclosures about its products, services,
geographic areas and major customers. The Company has determined that it does
not have any separately reportable business segments.

UNAUDITED INTERIM FINANCIAL INFORMATION

    The interim financial information of the Company for the six months ended
June 30, 1999 is unaudited. The unaudited financial information has been
prepared on the same basis as the annual financial statement statements and, in
the opinion of management, reflects all adjustments, consisting only of normal
recurring adjustments, necessary to present fairly the financial position,
results of operations and cash flows as of and for the six months ended June 30,
1999.

STOCK SPLIT

    Subsequent to June 30, 1999, the Company authorized and implemented a four
for one stock split and increased the authorized number of common shares and
preferred shares to 100,000,000 and 20,000,000, respectively. The share
information in the accompanying financial statements has been retroactivity
restated to reflect the effect of the stock split and increased number of
authorized shares.

RECENTLY ISSUED ACCOUNTING STANDARDS

    In March 1998, the Accounting Standards Executive Committee issued Statement
of Position No. 98-1 ("SOP 98-1"), "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use," which provides guidance on
accounting for the cost of computer software developed or obtained for internal
use. SOP 98-1 is effective for financial software statements for fiscal years
beginning after December 15, 1998. Implementation of SOP 98-1 did not have a
significant impact on the Company's financial position, results of operations or
cash flows.

    In April 1998, the Accounting Standards Executive Committee issued Statement
of Position No. 98-5 ("SOP 98-5"), "Reporting on the Costs of Start-Up
Activities." This standard requires companies

to expense the costs of start-up activities and organization costs as incurred.
In general, SOP 98-5 is effective for fiscal years beginning after December 13,
1998. Adoption of SOP 98-5 did not have a significant impact on the Company's
financial position, results of operations or cash flows.

    In June 1998, the Financial Accounting Standards Board issued Statement of
Accounting Standards No. 133, ("Statement No. 133"), Accounting for Derivative
Instruments and Hedging Activities. SFAS 133 establishes new standards of
accounting and reporting for derivative instruments and hedging activities. SFAS
133 requires that all derivatives be recognized at fair value in the statement
of financial position, and that the corresponding gains and losses be reported
either in the statement of operations or as a component of comprehensive income,
depending on the type of hedging relationship that exists. SFAS 133 will be
effective for fiscal years beginning after June 15, 2000. The Company does not
currently hold derivative instruments or engage in hedging activities.
Accordingly, management believes the adoption of this statement will not have a
significant impact on the Company's financial position, results of operations or
cash flows.

6. INCOME TAXES

    For the period from May 1, 1998 (inception) through December 31, 1998, the
Company was subject to the provisions of Subchapter K of the Internal Revenue
Code and as such the Company did not pay Federal income taxes. Instead, the
members were liable for individual Federal income taxes on the Company's taxable
income. California generally conforms to federal treatment, except for the
imposition of a minimum tax based on gross receipts. The Company's conversion
from a LLC to a C-corporation did not have a material impact on the Company's
financial position or results of operations.

    Upon conversion to a C-corporation, ValueClick commenced using the asset and
liability method of accounting for income taxes. Under this method, deferred tax
assets and liabilities are recognized for future taxable consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases, and to operating
loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in results of operations in the period that includes the
enactment date.

the acquisition of the Company by another entity), the holders of the preferred
stock have a liquidation preference over common stock. Upon payment of all
preferred stock liquidation preferences, any remaining proceeds will be
allocated to the common stockholders and the preferred stockholders according to
their respective shares and priorities on a converted basis.

    CONVERSION.  At the option of the holder, each share of preferred stock is
convertible at any time into one share of common stock, subject to adjustment
for certain dilutive issuances. As of June 30, 1999, following the four for one
common stock split, each share of the Series A, Series B and Series C shares are
convertible into four shares of common stock. The preferred shares automatically
convert into common stock upon consummation of an underwritten public offering
pursuant to an effective registration statement under the Securities Act of
1933, with an aggregate proceeds greater than or equal to $20,000,000.

8. STOCK OPTION PLAN

    On May 13, 1999, the Board of Directors adopted and the stockholders
approved, the 1999 Stock Option Plan (the "1999 Stock Plan"). A total of
6,080,000 shares of common stock have initially been reserved for issuance under
the 1999 Stock Plan, of which 1,264,800 shares were available for future grant
at June 30, 1999.

    In January 1999, options to purchase 1,500,000 shares of common stock were
granted outside the 1999 Stock Plan and were subsequently included in the shares
reserved under the 1999 plan. 1,200,000 of these shares were granted to the
Chairman of the Board.

    The 1999 Stock Option Plan provides for the granting of nonstatutory and
incentive stock options to employees, officers, directors and consultants of the
Company. Options granted generally begin vesting six months after the vesting
start date, generally the employee's date of employment, and vest pro rata
monthly over periods ranging from 12 to 42 months and generally expire ten years
from the date of grant. In addition, certain employees have options that have
accelerated vesting upon certain events including the closing of an initial
public offering of the Company's stock or the transfer of ownership of 50% or
more of the Company's stock.

    The following table summarizes activity under the Stock Option Plan for the
period from May 1, 1998 (inception) through December 31, 1998 and the six months
ended June 30, 1999:

    Options granted during the six months ended June 30, 1999 resulted in a
total deferred compensation amount of $2,711,833 which was included in deferred
stock compensation in stockholders' equity. Deferred compensation expense is
recognized over the service period by using the aggregate percentage of
compensation accrued by the end of each year of service (the vesting period).
During the six months ended June 30, 1999, such compensation expense included in
stock-based compensation in the statement of operations amounted to $298,015

    The compensation cost associated with the Company's stock-based compensation
plan, determined using the minimum value option pricing model did not result in
a material difference from the reported net loss for the six months ended June
30, 1998.

9. NET LOSS PER SHARE

    The Company's historical capital structure prior to December 31, 1998 is not
indicative of its prospective structure as a result of its conversion and
reincorporation from a California LLC to a Delaware C-corporation on December
31, 1998. Accordingly, the historical net loss per share for the period May 1,
1998 (inception) through December 31, 1998 has been presented on a historical
basis as if the Company had been a C-corporation.

EMPLOYMENT AGREEMENTS

12. SUBSEQUENT EVENTS

    On August 6, 1999, the Company acquired an additional 22.3 percent of
ValueClick Japan's common stock to increase its investment in ValueClick Japan
to approximately 54% in exchange for 640,000 shares of common stock of
ValueClick valued at $1,280,000. The Company will consolidate this investment.

    On August 17, 1999, the Company entered into a license agreement and
invested $99,000 for a 20% interest in ValueClick Europe, Limited, formed in
August 1999 to engage in the web-based-Internet advertising business in the
United Kingdom. The Company will account for this investment using the equity
method of accounting.

    On October 8, 1999, the Board of Directors authorized the filing of a
registration statement with the Securities and Exchange Commission ("SEC") that
would permit the Company to sell shares of the Company's common stock in
connection with a proposed initial public offering ("IPO"). If the IPO is
consummated under the terms presently anticipated, upon the closing of the
proposed IPO, all of the then outstanding shares of the Company's convertible
preferred stock will automatically convert into shares of common stock on a
one-for-one basis, subject to antidilution provisions.

    On October 8, 1999, the Board of Directors approved increasing the number of
shares of common stock reserved for issuance under the 1999 Stock Plan to
8,000,000 shares.

                 INTRODUCTION TO UNAUDITED PRO FORMA CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS

    On August 6, 1999, ValueClick, Inc. ("ValueClick") entered into a Stock
Purchase Agreement (the "Agreement") to acquire a controlling interest in
ValueClick Japan. Prior to entering into the Agreement, ValueClick had a 31.7%
ownership interest in ValueClick Japan, which was accounted for using the equity
method of accounting. Under the Agreement, ValueClick purchased an additional
22.3% of the ValueClick Japan stock in exchange for 640,000 shares of ValueClick
common stock with an estimated fair value of $1,280,000 giving ValueClick a
54.0% controlling ownership interest in ValueClick Japan. The acquisition will
be accounted for using the purchase method. The purchase price will be allocated
to the estimated fair value of assets acquired and liabilities assumed to the
extent acquired by ValueClick. The remaining portion of the ValueClick Japan
assets and liabilities will be recorded at the historical cost basis of the
minority stockholders. The preliminary purchase price allocation is based on
available information but there can be no assurance that the actual results will
not differ significantly from the pro forma adjustments reflected in the pro
forma condensed consolidated financial statements. The preliminary purchase
price allocation indicates additional intangible assets, totaling $1,241,000,
which will be amortized on a straight-line basis over the estimated lives
ranging from 3 to 5 years.

    The following unaudited pro forma condensed consolidated balance sheet as of
June 30, 1999 assumes that the acquisition was consummated on June 30, 1999. The
following unaudited pro forma consolidated statements of operations for the
periods from May 1, 1998 (Inception) through December 31, 1998 and the six
months ended June 30, 1999 give effect to the acquisition as if it had occurred
on May 1, 1998.

    The unaudited pro forma condensed consolidated financial statements are not
necessarily indicative of the results that would have occurred if the
acquisition had occurred as of the beginning of the period presented and should
not be construed as being representative of future operating results.

    The unaudited pro forma condensed consolidated financial statements should

of ValueClick, LLC. The ValueClick Line of Business began the Internet
advertising delivery business in July 1997. Effective April 30, 1998, the
founding member caused Web-Ignite to transfer the rights to the ValueClick
Trademark, the rights to the ValueClick domain names, the rights to the
trademark, license, software license and copyright agreements within
Trans-Pacific Ltd., predecessor to ValueClick Japan and the rights to the ad
delivery software used in the business to ValueClick, LLC. The reorganization
and formation of ValueClick, LLC was accounted for as a transaction by entities
under common control.

    The ValueClick Line of Business was an Internet based advertising network
that provided a performance based advertising solution on a cost-per-click to
advertisers and e-commerce companies.

    The accompanying statements present the financial position at December 31,
1997 and April 30, 1998 and the results of operations and cash flows for the
period from July 1, 1997 (inception) to December 31, 1997 and the four months
ended April 30, 1998 for the ValueClick Line of Business. Web-Ignite did not
account for the ValueClick Line of Business as a separate entity. Accordingly,
the information included in the accompanying financial statements has been
obtained from Web-Ignite's financial records. The statements of operations
include revenues, cost of revenue and operating expenses as maintained in
Web-Ignite's general ledger attributed to the ValueClick Line of Business.
Certain operating expenses presented in these financial statements were
allocated by management of Web-Ignite based on estimates of the cost of services
provided to ValueClick Line of Business by Web-Ignite. Management believes the
allocation methodologies used were reasonable. However, these allocations may
not be indicative of future operating expenses required by a separate business
operation.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

    The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

REVENUE RECOGNITION

    The ValueClick Line of Business's revenues were principally derived from the
delivery of advertising click-throughs through third-party Web sites comprising
the ValueClick Network (the "Network"). Revenue is recognized in the period that
the advertising click-throughs occur, provided that no significant obligations
remain and collection of the resulting receivable is probable.

COST OF REVENUES

    The ValueClick Line of Business becomes obligated to make payments to
third-party websites, which have contracted with the ValueClick Line of Business
to be part of the Network, in the period the advertising click-throughs are
delivered. Such expenses are classified as cost of revenues in the accompanying
statement of operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
OPERATING EXPENSES

    Operating expenses consist of personnel and personnel related costs incurred
directly by the ValueClick Line of Business. Operating expenses also include
other costs, including office, facilities, management systems and general
corporate expenses. Certain operating expenses were allocated to the ValueClick
Line of Business. Management believes the allocation methodologies used were
reasonable. However, these allocations may not be indicative of what the
expenses would have been had the ValueClick Line of Business been a separate
entity or future operating expenses required by a separate business operation.

CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subjected the ValueClick Line of
Business to concentration of credit risk consist of cash and accounts
receivable. Cash was deposited with major financial institutions; at times, such
balances with any one financial institution may be in excess of FDIC insurance
limits. Credit was extended to customers based on an evaluation of their
financial condition. The ValueClick Line of Business did not generally require
collateral. The ValueClick Line of Business performed ongoing credit evaluations
of its customers and maintains an allowance for potential bad debt. To date such
losses, if any, have been within management's expectations.

COMPREHENSIVE INCOME

    The ValueClick Line of Business adopted the provisions of SFAS No. 130,
"Reporting Comprehensive Income" ("Statement No. 130"). Statement No. 130
establishes standards for reporting comprehensive income and its components in
financial statements. Comprehensive income, as defined, includes all changes in
equity (net assets) during a period from nonowner sources. To date, the
ValueClick Line of Business has not had any transactions that were required to
be reported in comprehensive income.

3. INCOME TAXES

    Web-Ignite operated as an S-corporation and as such was not subject to
federal and state income taxes. Accordingly, no separate tax provision was
required for the ValueClick Line of Business.

4. COMMITMENTS AND CONTINGENCIES

    There were no separate leases or other commitments and contingencies related
to the ValueClick Line of Business.

5. INVESTED EQUITY

    Invested equity represents the equity contributed to the ValueClick Line of
Business and related accumulated results of operations of the ValueClick Line of
Business.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of ValueClick Japan

    In our opinion, the accompanying balance sheet and the related statements of
operations, stockholders' equity and cash flows present fairly, in all material
respects, the financial position of ValueClick Japan (the "Company") at December
31, 1998, and the results of its operations and its cash flows for the period
from November 16, 1998 (legal inception) through December 31, 1998, and the
results of operations of its predecessor line of business within Trans-Pacific
Ltd. for the period from March 26, 1998 (business inception) through November
15, 1998, in conformity with generally accepted accounting principles. 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 of these financial statements in accordance
with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

                         NOTES TO FINANCIAL STATEMENTS

          (ALL INFORMATION WITH RESPECT TO JUNE 30, 1999 IS UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BASIS OF PRESENTATION

    ValueClick Japan (the "Company") was incorporated as a Japanese joint stock
corporation on November 16, 1998. Prior to its incorporation, the business was
operated as a line of business of Trans-Pacific Ltd. ("Trans-Pacific"), which,
on March 22, 1998, entered into a Trademark License, Software License and
Copyright Agreement (the "Agreement") with Web-Ignite Corporation ("Web-Ignite")
to use the ValueClick Advertising Network (the "Network") in Japan. Effective
November 16, 1998, Trans-Pacific contributed the rights under the Agreement to
the Company.

    Effective January 1, 1999, Trans-Pacific and Web-Ignite confirmed their
assignment of all of their respective rights under the Agreement to ValueClick
Japan and ValueClick, Inc. ("ValueClick"), the successor to Web-Ignite, and
entered into a License and Option Agreement.

    For the period from March 22, 1998 through November 15, 1998, the financial
statements have been prepared using Trans-Pacific's historical results of
operations related to ValueClick Japan Line of Business. Trans-Pacific did not
account for this line of business as a separate entity. Accordingly, certain
costs and expenses presented in these financial statements were allocated by the
management of Trans-Pacific based on their estimates of the cost of services
provided to ValueClick Japan Line of Business by Trans-Pacific. Trans-Pacific
management believes that these allocations and allocation methods are
reasonable. However, the financial information included herein for the
ValueClick Japan Line of Business may not necessarily be indicative of the
future results of operations of ValueClick Japan.

UNAUDITED INTERIM FINANCIAL INFORMATION

    The interim financial information of the Company for the six months ended
June 30, 1999 is unaudited. The unaudited financial information has been
prepared on the same basis as the annual financial statements and, in the
opinion of management, reflect all adjustments, consisting only of normal
recurring adjustments, necessary to present fairly the financial position,
results of operations and cash flows as of and for the six months ended June 30,
1999.

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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates.

CASH AND CASH EQUIVALENTS

    The Company considers all short-term investments with an original maturity
of three months or less to be cash equivalents. At December 31, 1998, cash
equivalents consist of money market funds.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

          (ALL INFORMATION WITH RESPECT TO JUNE 30, 1999 IS UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Depreciation on property and
equipment is calculated on the straight-line method over the estimated useful
lives of the assets ranging from 3 to 5 years. Leasehold improvements are
amortized over their estimated useful lives, or the term of the leases,
whichever is shorter.

INCOME TAXES

    The operations of the ValueClick Japan line of business have been included
in the foreign income tax return of Trans-Pacific up through November 15, 1998.
Income taxes are accounted for under Statement of Financial Accounting Standards
("SFAS") Statement No. 109, "Accounting for Income Taxes" ("Statement No. 109").
Statement No. 109 requires that the deferred tax assets and liabilities be
determined based on differences between the financial reporting and tax basis of
assets and liabilities, and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.

REVENUE RECOGNITION

    The Company's revenues are principally derived from the delivery of
advertising click-throughs through third-party Web sites comprising the Network.
Revenue is recognized in the period the advertising click-throughs occur,
provided that no significant Company obligations remain and collection of the
resulting receivable is probable. To date, the Company's agreements have not
required guaranteed minimum click-throughs.

    The Company becomes obligated to make payments to third-party Web sites,
which have contracted with the Company to be part of the Network, in the period
the advertising click-throughs are delivered. Such expenses are classified as
cost of revenues in the accompanying statements of operations

    Deferred revenue represents payments received in advance for advertising
click-throughs. Such fees will be recognized as revenues once the advertising
click-throughs are delivered and no significant Company obligations remain.

TECHNOLOGY ENHANCEMENTS

    Technology development costs and enhancements to existing products are
charged to operations as incurred. These costs have not been significant during
the periods presented.

CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Company to concentration
of credit risk consist of trade receivables. Credit is extended to customers
based on an evaluation of their financial condition. The Company generally does
not require collateral. The Company performs ongoing credit evaluations of its
customers and maintains reserves for potential credit losses. For the period
from November 16, 1998 (inception) through December 31, 1998, 3 customers
comprised 21%, 12% and

11% of revenues, respectively. At December 31, 1998, 2 customers comprised 15%
and 13% of accounts receivable, respectively. At June 30, 1999, 1 customer
comprised 12% of revenues, and one customer comprised 12% of accounts
receivable.

FOREIGN CURRENCY TRANSLATION

    ValueClick Japan denominates its transactions in the Japanese Yen. Assets
and liabilities are translated at the exchange rate as of the balance sheet
date. All revenue and expense accounts are translated using a average of
exchange rates in effect during the year. Cumulative foreign currency
translation adjustments are recorded as a separate component of stockholders'
equity.

FINANCIAL INSTRUMENTS

    The Company's financial instruments, including cash and cash equivalents,
accounts receivable, accounts payable and short-term debt, are carried at
historical cost, which approximates their fair values.

IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF

    The Company evaluates its long-lived assets for impairment whenever events
or changes in circumstances indicate that the carrying amount of such assets or
intangibles may not be recoverable. Recoverability of assets to be held and used
is measured by a comparison of the carrying amount of an asset to future
undiscounted net cash flows expected to be generated by the asset. If such
assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets exceeds the
fair value of the assets. To date, no such impairment has been recorded.

COMPREHENSIVE INCOME

    The Company adopted the provisions of SFAS No. 130, "Reporting Comprehensive
Income" ("Statement No. 130"). Statement No. 130 establishes standards for
reporting comprehensive income and its components in financial statements.
Comprehensive income, as defined, includes all changes in equity (net assets)
during a period from nonowner sources. To date, the only transactions that are
required to be reported as comprehensive income relate to foreign currency
translation adjustments.

SEGMENTS

    Effective November 16, 1999, the Company adopted the provisions of SFAS No.
131, "Disclosures About Segments of an Enterprise and Related Information"
("Statement No. 131"). Statement No. 131 establishes standards for the way
companies report information about operating segments in annual financial
statements. It also establishes standards for related disclosures about its
products, services, geographic areas and major customers. The Company has
determined that it does not have any separately reportable business segments.

RECENTLY ISSUED ACCOUNTING STANDARDS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("Statement No. 133"), which defines
derivatives, requires that all derivatives be carried at

fair value, and provides for hedge accounting when certain conditions are met.
Statement No. 133 is effective for the Company in fiscal 2000. Although the
Company has not fully assessed the implications of Statement No. 133, the
Company does not believe that adoption of this statement will have a material
impact on the Company's financial position or results of operations.

2. PROPERTY AND EQUIPMENT

    Property and equipment as of December 31, 1998 and June 30, 1999 consisted

3. RELATED PARTY TRANSACTIONS

    The Company and ValueClick are subject to the Agreement to use the Network
in Japan, which has been subsequently amended to the License and Option
Agreement. This agreement requires a monthly license fee based on the Company's
revenue, subject to monthly and quarterly minimum thresholds. This agreement has
a minimum revenue requirement based on a rolling three-months.

    At December 31, 1998, $10,263 was due under the agreement to ValueClick,
Inc. and $21,000 was due for activity for the six months ended June 30, 1999.
The outstanding balances due to ValueClick, Inc. are included in the payable to
ValueClick, Inc. in the accompanying balance sheets.

    In December 1998, the Company borrowed approximately $8,800 from a related
party. This obligation did not require interest payments. In January 1999, the
amount borrowed was repaid.

    The Company leases a portion of the Network's infrastructure from a related
party on a month-to-month basis. Management believes that these costs are not
significant during the periods presented.

4. INCOME TAXES

    Prior to November 16, 1998, the ValueClick Japan Line of Business was
operated as a division of Trans-Pacific, with any local income taxes recorded by
Trans-Pacific. From the date of incorporation, the Company has not recorded a
provision for its local country income taxes due to net operating losses
generated from operations. The Company may be able to carryforward these net
operating losses to offset future taxable income for a period of up to five
years, subject to utilization limitations, which may inhibit the Company's
ability to use the carryforwards in the future. Due to the uncertainty
surrounding the realization of the tax benefits in the future tax returns,
management has recorded a full valuation reserve against the deferred tax
assets.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Under Section 145 of the Delaware General Corporation Law, we can indemnify
our directors and officers against liabilities they may incur in such
capacities, including liabilities under the Securities Act of 1933, as amended
(the "Securities Act"). Our certificate of incorporation will provide that,
pursuant to Delaware Law, our directors shall not be liable for monetary damages
for breach of the directors' fiduciary duty of care to ValueClick and our
stockholders. This provision in the certificate of incorporation does not
eliminate the duty of care, and in appropriate circumstances equitable remedies
such as injunctive or other forms of nonmonentary relief will remain available
under Delaware law. In addition, each director will continue to be subject to
liability for breach of the director's duty of loyalty to ValueClick or our
stockholders, for acts or omissions not in good faith or involving intentional
misconduct or knowing violatios of the law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are unlawful under Delaware Law. The
provision also does not affect a director's responsibilities under any other
law, such as the federal securities laws or state or federal environmental laws.

    Our bylaws will provide that we will indemnify our directors and officers to
the fullest extent permitted by law and require us to advance litigation
expenses upon our receipt of an undertaking by the director or officer to repay
such advances if it is ultimately determined that the director or officer is not
entitled to indemnification. Our bylaws will further provide that rights
conferred under such bylaws do not exclude any other right such persons may have
or acquire under any bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.

    We also have directors' and officers' liability insurance. In addition,
prior to the closing of this offering, we will enter into agreements to
indemnify our directors and certain of our officers in addition to the
indemnification provided for in the certificate of incorporation and bylaws.
These agreements will, among other things, indemnify our directors and certain
of our officers for certain expenses (including attorneys fees), judgments,
fines and settlement amounts incurred by such person in

                                      II-1
<PAGE>
any action or proceeding, including any action by or in our right, on account of
services by that person as a director or officer of ValueClick or as a director
or officer of any subsidiary of ValueClick, or as a director or officer of any
company or enterprise that the person provides services to at the request of
ValueClick.

    The Underwriting Agreement provides for indemnification by the underwriters
of ValueClick and its officers and directors, and by ValueClick of the
underwriters, for certain liabilities arising under the Securities Act or
otherwise.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

    The following is a summary of transactions by ValueClick since its inception
in May 1998 involving sales of our securities that were not registered under the
Securities Act of 1933, as amended:

    In May 1998, ValueClick, LLC issued securities equal to 6% of its total
equity to a total of six investors for an aggregate purchase price of $55,000
and issued securities equal to 77% of its total equity to four individuals in
consideration of certain trademarks, software and trademark licenses and
contractual rights. In June 1998, ValueClick, LLC issued securities equal to 17%
of its total equity to a total of ten investors for an aggregate purchase price
of $716,000.

    On December 31, 1998, ValueClick, LLC was reorganized as ValueClick, Inc., a
Delaware corporation, and entered into an Exchange Agreement pursuant to which
ValueClick, Inc. issued to ValueClick, LLC 19,952,024 shares of ValueClick
common stock, 297,132 shares of Series A Convertible Preferred Stock and
1,047,804 shares of Series B Convertible Preferred Stock for distribution to the
members of ValueClick, LLC upon its dissolution and agreed to assume ValueClick,
LLC's liabilities, in exchange for ValueClick, LLC's assets.

    From January through June 1999, we issued a total of 1,301,850 shares of
Series C convertible preferred stock to 24 investors, at $2.70 per share, for an
aggregate price of approximately $3.5 million.

    From May 1, 1998 to September 30, 1999, we granted options to purchase an
aggregate of 5,489,200 shares of common stock to our directors, executive
officers, employees and consultants at a weighted average exercise price of
$0.42 per share. As of September 30, 1999, no options had been exercised.

    In May 1999, we issued an aggregate of 1,217,756 shares of our common stock
to six employees in exchange for an equal number of shares of common stock
pursuant to Stock Exchange and Restriction Agreements with each of these
stockholders which placed transfer restrictions on the exchanged shares.

    In August 1999, we issued 640,000 shares of our common stock to two holders
of shares of ValueClick Japan, in exchange for shares in ValueClick Japan equal
to 22.3% of the outstanding equity of ValueClick Japan.

    The issuances of the above securities were exempt from registration under
the Securities Act in reliance on Section 4(2) or Regulation D of the Securities
Act as transactions by an issuer not involving any public offering or Rule 701
under the Securities Act. The recipients of securities in each transaction
represented their intentions to acquire the securities for investment only and
not with a view to or for sale in connection with any distribution thereof and
appropriate legends were affixed to the share certificates and warrants issued
in these transactions. All recipients had adequate access, through their
relationships with the Registrant, or otherwise, to information about the
Registrant.

        See Exhibit Index at page II-6.

    (b) Financial Statement Schedules

        None required.

ITEM 17. UNDERTAKINGS

    The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in
denominations as required by the underwriters and registered in 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 foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
indemnification is against public policy as expressed in the Securities Act, and
is, therefore, unenforceable. In the event that a claim for indemnification
against 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 a
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 indemnification by it is against public policy
as expressed in the Securities Act and will be governed by the final
adjudication of this 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 this offering of these securities at that time shall be deemed to be the
initial bona fide offering thereof.

                               EXCHANGE AGREEMENT


                  THIS EXCHANGE AGREEMENT is made as of December 31, 1998, by
and among ValueClick, Inc., a Delaware corporation (the "Company"), and
ValueClick, LLC, a California limited liability company (the "Stockholder"),
with reference to the following facts:

                  The parties hereto desire to enter into an agreement under
the terms of which the Stockholder will contribute all of its assets (the
"Assets") to the capital of the Company on the Company's initial
organization, in exchange for the following shares of the Company's
authorized and unissued capital stock: 4,655,063 shares of Common Stock, par
value $0.001 per share, 297,132 shares of Series A Convertible Preferred
Stock, par value $0.001 per share, and 1,047,804 shares of Series B
Convertible Preferred Stock, par Value $0.001 per share, all such shares
being herein collectively called the "Shares". Immediately after the
contribution of the Assets in exchange for the Shares, the Stockholder will
dissolve and distribute the Shares to its members, as their interests may
appear.

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants and agreements herein and in consideration of the
contribution by Stockholder to the Company of the Assets, receipt of which is
hereby acknowledged by the Company, the parties agree as follows:

         1. REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER. The
Stockholder represents and warrants to and agrees with the Company:

                  1.1 REVIEW OF DOCUMENTS. The Stockholder acknowledges
having had access to all of the books and records of the Company and having
conducted a thorough and comprehensive investigation of the Company. The
Stockholder is entering into this Agreement and the transactions contemplated
hereby solely in reliance on its own investigation.

                  1.2 ACQUISITION OF SHARES FOR OWN ACCOUNT. The Stockholder
is acquiring Shares pursuant to this Agreement with the Stockholder's own
funds, for the Stockholder's own account, not as a nominee or agent, except
that the Stockholder intends forthwith to dissolve and distribute the Shares
to its members.

                  1.3 RESTRICTED NATURE OF SHARES. The Stockholder and its
members are able to bear the economic risk of the Stockholder's investment in
the Shares and are aware that they must be prepared to hold the Shares for an
indefinite period and that the Shares have not been registered under the
Securities Act of 1933, as amended (the "Act"), or registered or qualified
under the California Corporate Securities Law of 1968, as amended (the
"Law"), or any other securities law, on the ground, among others, that no
distribution or public offering of Shares is to be effected and Shares are
being issued by the Company without any public offering within the meaning of
section 4(2) of the Act and Regulation D thereunder, and comparable
provisions of the Law and other state securities laws.


                                      1
<PAGE>

                  1.4 SOPHISTICATION. The Stockholder's principal executive
officer acting on behalf of the Stockholder and each member of the
Stockholder have such knowledge and experience in financial and business
matters that he or she is capable of evaluating the merits and risks of the
investment by the Stockholder and its members contemplated by this Agreement
and has the capacity to protect the interests of the Stockholder or such
member, respectively.

                  1.5 AGREEMENT TO REFRAIN FROM RESALES. The Stockholder, for
itself and its members, further agrees that they shall not encumber, pledge,
hypothecate, sell, transfer, assign or otherwise dispose of (except as
provided in section 3), or receive and consideration for, any Shares or any
interest in any Shares, unless and until prior to any proposed encumbrance,
pledge, hypothecation, sale, transfer, assignment or other disposition,
either (a) a registration statement on Form S-1 (or any other form
appropriate for the purpose or replacing such form) under the Act with
respect to the Shares proposed to be transferred or otherwise disposed of
shall be then effective or (b)(1) the Stockholder and its members shall have
furnished the Company with a detailed statement of the circumstances of the
proposed disposition, (2) the Stockholder and its members shall have
furnished the Company with an opinion of counsel (obtained at their expense)
in form and substance satisfactory to the Company to the effect that such
disposition will not require registration of such Shares under the Act or
registration or qualification of such Shares under the Law or any other
securities law and (3) counsel for the Company shall have concurred in such
opinion of counsel.

                  1.6 CERTIFICATES TO BE LEGENDED. The Stockholder
understands and agrees that each certificate representing Shares will bear a
legend on the face thereof (or on the reverse thereof with a reference to
such legend on the face thereof) in substantially the form set forth below,
which legend restricts the sale, transfer or other disposition of Shares
otherwise than in accordance with this Agreement:

         THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THESE SHARES MAY NOT BE
         ENCUMBERED, PLEDGED, HYPOTHECATED, SOLD, ASSIGNED, TRANSFERRED OR
         OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
         STATEMENT FOR THE SHARES UNDER SAID ACT OR AN OPINION OF COUNSEL
         SATISFACTORY IN FORM AND SUBSTANCE TO THE CORPORATION AND CONCURRED IN
         BY THE CORPORATION'S COUNSEL TO THE EFFECT THAT SUCH REGISTRATION IS
         NOT REQUIRED UNDER SAID ACT OR SUCH TRANSACTION COMPLIES WITH RULES
         PROMULGATED BY THE SECURITIES AND EXCHANGE COMMISSION UNDER SAID ACT.

The Stockholder also understands and agrees that each certificate
representing Shares may also contain any legend required by the California
Commissioner of Corporations which may further restrict transfers of the
Shares.


                                      2
<PAGE>

                  1.7 SHARES WILL BE "RESTRICTED SECURITIES". The Stockholder
understands and agrees that the Shares will be "restricted securities" as
that term is defined in Rule 144 under the Act and, accordingly, that the
Shares must be held indefinitely unless they are subsequently registered
under the Act or an exemption from such registration is available.

                  1.8 COMPANY MAY REFUSE TO TRANSFER. If at any time, in the
opinion of counsel for the Company, the Stockholder or any of its members has
acted or acts in any manner not consistent with the representations and
agreements of the Stockholder in this Agreement, the Company may refuse to
transfer the Stockholder's or any such member's Shares until such time as
counsel for the Company is of the opinion that such transfer is in all
respects in compliance with this Agreement and will not require registration
of such Shares under the Act or registration or qualification of such Shares
under any other securities law.

                  1.9 SURVIVAL. All representations and warranties in this
Agreement shall survive the consummation of the transactions contemplated by
this Agreement.

         2. ISSUANCE OF SHARES. Subject to and in reliance on the
representations, warranties and agreements of the parties, the Stockholder
hereby contributes to the Company all of the Assets in exchange for the
Shares, and the Company hereby assumes all of the debts, duties, obligations
and liabilities of the Stockholder. To evidence such contribution and
assumption, the Stockholder and the Company each represent that they have
duly executed and are delivering herewith to each other a Bill of Sale and
Assignment and Assumption of Liabilities in the form of Exhibit A attached
hereto.

         3. DISSOLUTION OF STOCKHOLDER. The Company acknowledges that the
Stockholder intends forthwith to dissolve and distribute the Shares to the
members of the Stockholder in accordance with the interests of such members.
The Company hereby consents to such distribution.

         4. APPROVALS. The Company agrees to apply for, and use its best
efforts to obtain, all governmental and administrative approvals required in
connection with the issuance of Shares under this Agreement. The parties
agree to cooperate in obtaining such approvals and to execute any and all
documents or instruments that, in the opinion of the Company, may be
required, appropriate or desirable to be executed by them in connection with
such approvals. The Company shall pay all costs and filing fees in connection
with obtaining such approvals. This section 4 shall not be construed or
interpreted to alter the provisions of section 1 and, in particular, shall
not be deemed to impose on the Company any obligation to cause any securities
to be registered under the Act or registered or qualified under the Law or
any other securities law or to comply with the conditions for any exemption
from the registration provisions of the Act or the registration or
qualification provisions of the Law or any other securities law, except with
respect to compliance on initial issuance of the Shares with the Act, the Law
and all other applicable securities laws.

         5. FURTHER ASSURANCES. The parties shall do or perform any and all
such further acts and things and execute and deliver any and all such
documents and instruments as may be reasonably necessary to carry out the
provisions of this Agreement.

<PAGE>

         6. RESTRICTIONS TO RUN WITH SHARES. The covenants, conditions and
restrictions herein shall be and constitute convenants, conditions and
restrictions running with all of the Shares, and none of the Shares shall be
sold, assigned, transferred, encumbered, pledged, hypothecated, given as a
gift or otherwise disposed of or alienated in any way by any person except in
accordance with this Agreement. The parties agree that stop order
instructions prohibiting transfer of certificates for Shares will be issued
and filed by the Company on its records or with the Company's transfer agent
to prevent any disposition otherwise than strictly in accordance with this
Agreement and agree to cause the officers of the Company to refuse to record
on the books of the Company any assignments or transfers made or attempted to
be made except in accordance with this Agreement and to cause said officers
to refuse to cancel certificates, or issue or deliver new certificates
therefor, where the purchaser, assignee, pledgee, donee or other transferee
has acquired certificates or any Shares represented thereby otherwise than
strictly in accordance with this Agreement. Any person who acquires any
Shares or any interest therein shall hold such Share or interest subject to
this Agreement.

         7. SUCCESSORS AND ASSIGNS. Without limiting the restrictions on
transfers herein, this Agreement shall bind and inure to the benefit of and
be enforceable by the Company, the Stockholder and the members of the
Stockholder and their respective successors, assigns, personal or legal
representatives, heirs and legatees, whether herein so expressed or not.

         8. SHARES MAY BE FURTHER RESTRICTED. The Stockholder understands and
agrees that, if the Company at any time proposes to sell shares of its Common
Stock in a public offering registered under the Act or exempt from
registration under the Act under Regulation A promulgated under the Act, (a)
the Stockholder will enter into any agreement requested by the Company or
underwriters of such offering, prohibiting any disposition of the Shares for
a period not in excess of six months after the date of such offering, and (b)
the Stockholder will enter into any agreement that the Company may consider
necessary for the successful completion of such public offering under the
securities or Blue Sky laws of certain states that require as a condition of
registration or such exemption that some or all of the Shares be deposited in
an escrow or be subject to waivers of rights to dividends to assets on
liquidation, or both, for an extended period of time, subject to release if
certain financial or market requirements are met and partial cancellation if
such requirements are not met.

         9. NOTICES. All notices, requests, demands and other communications
hereunder must be in writing and shall be deemed to have been duly given and
received when delivered personally, when transmitted by facsimile if receipt
is acknowledged by the addressee, one day after being deposited for next-day
delivery with a nationally recognized overnight delivery service, or three
days after being mailed by first class mail, charges and postage prepaid, and
properly addressed, if to the Company, at its principal executive office, or
if to the Stockholder or any of its members, at the Stockholder's or
member's address as it appears on the records of the Company, or any other
address that any party may designate by notice to the others.

         10. ENTIRE AGREEMENT. This Agreement contains the entire agreement
of the parties and supersedes all prior or contemporaneous negotiations,
correspondence, understandings and agreements, written or oral, between the
parties hereto, regarding the subject matter hereof.

         12. HEADINGS. The headings of sections hereof are for convenience of
reference only and are not part of this Agreement.

         13. CALIFORNIA SECURITIES LAW. The sale of the securities which are
the subject of this Agreement has not been qualified with the Commissioner of
Corporations of the State of California and the issuance of such securities
or the payment or receipt of any part of the consideration therefor prior to
such qualification is unlawful, unless the sale of securities is exempt from
the qualification by section 25100, 25102 or 25105 of the Law. The rights of
all parties to this Agreement are expressly conditioned on such qualification
being obtained, unless the sale is so exempt or such qualification provisions
are preempted by Federal law.

                  IN WITNESS WHEREOF, this Agreement has been duly executed
by or on behalf of the parties hereto as of the date first above written.

Improvements to the System.

       14.    OPTION TO ACQUIRE LICENSEE.

              14.1   GRANT OF OPTION.  In consideration for the execution of
this Agreement by Licensor and for other good and valuable consideration from
Licensor, the sufficiency and receipt of which is hereby acknowledged by
Licensee, Licensee grants Licensor an exclusive option (the "Option"), which may
be exercised by Licensor at any time during the term of this Agreement or during
any extension or renewal thereof, to acquire all, but not less than all, of the
outstanding shares of capital stock of Licensee (the "Licensee Stock") in
exchange for shares of the common stock of Licensor (the "Licensor Stock"), the
number of which shares of Licensor Stock shall be determined in accordance with
the provisions of Section 14.4.  It is an express condition of this Option that
it may only be exercised by Licensor in the event that Licensor engages in or is
a party to one of the following transactions and exercises the Option in
connection with such transaction:  (i) a sale of all or substantially all of the
assets of Licensor, (ii) a merger, combination, pooling or other reorganization
involving Licensor, or (iii) a public offering of a class of securities issued
by Licensor pursuant to a registration statement filed with the United States
Securities and Exchange Commission (each, a "Transaction").  In the event that
Licensor engages in or notifies Licensee of its intention to engage in any such
Transaction, Licensor may elect, in its sole and absolute discretion, to
exercise the Option and acquire all of the Licensee's stock in a stock-for-stock
exchange (the "Stock Swap").

              14.2   PROCEDURE FOR EXERCISE.  If Licensor elects to exercise the
Option, Licensor shall notify Licensee in writing of its election and in such
notice shall also identify the nature of the Transaction and the anticipated
timing of the Transaction.  Upon receipt of such notice, Licensee shall
thereafter not issue, exchange, dividend, redeem, transfer or otherwise engage
in any transaction involving the Licensee Stock.  Licensor and Licensee shall
each promptly take all actions necessary or advisable to effect the Stock Swap,
including but not limited to the calculation of the Exchange Ration in
accordance with Section 14.4, and to cause the Stock Swap to occur prior to the
scheduled closing date for the Transaction.  Licensor and Licensee shall agree
on a closing date for a Stock Swap and, at such Closing, the shareholders of
Licensee shall execute and deliver to Licensor stock certificates representing
all the issued and outstanding shares of Licensee Stock, and Licensor shall
issue to shareholders of Licensee the respective number of shares of Licensor
Stock to be issued to each shareholder of Licensee pursuant to the Exchange
Ratio determined according to Section 14.4.

              14.3   CONSENT OF LICENSEE'S SHAREHOLDERS.  Licensee represents
that, as of the Effective Date and as of the date this Agreement is executed,
the only shareholder of Licensee is Jonathon Hendriksen.  By executing this
Agreement on the signature line


                                      10

<PAGE>

set forth below, Mr. Hendriksen hereby consents to the grant of the Option on
the terms set forth herein, and agree to take all actions and execute and
deliver all documents necessary or desirable to effect the Stock Swap upon
exercise of the Option by Licensor, and Mr. Hendriksen agrees that the
valuation formula in Section 14.4 is fair, just and reasonable for purposes
of determining the Exchange Ratio for the Stock Swap.  Licensor and Mr.
Hendriksen agree that any person who becomes a shareholder of Licensee shall
be required, as a condition of such admission, to approve in writing the
Option and the other matters described in this section 14.3.

              14.4   DETERMINATION OF EXCHANGE RATIO.  To determine the Exchange
Ratio to be used to calculate the number of shares of Licensor Stock to be
issued to the shareholders of Licensee in connection with the Stock Swap upon
exercise by Licensor of the Option (the "Exchange Ratio"), Licensor and Licensee
agree that the valuation of Licensee for such purposes shall be determined in
the same manner and according to the same formula and assumptions (including but
not limited to valuation of intangible assets, marketability discounts, the
effect of external considerations, etc.) as are used and applied to determine
the value of Licensor for purposes of the Transaction.  For example, if the
valuation of Licensor for the Transaction is based on a multiple of annual gross
revenues, the same approach and calculation shall be used to determine the
valuation of Licensee; provided, that the valuation of Licensee resulting from
such determination shall be subject to a discount of twenty-five percent (25%)
for purposes of calculating the Exchange Ratio (e.g. if the initial valuation of
Licensee determined in accordance with this Section 14.4 is $1,000,000, the
actual valuation of Licensee used for purposes of calculating and determining
the Exchange Ratio shall be $750,000).  In any event, the minimum valuation of
Licensee for determining the Exchange Ratio shall be (i) two (2) times the
annual revenue of Licensee, plus (minus) (ii) ten (10) times the net profit (net
loss) of Licensee for that year.

       15.    MISCELLANEOUS.

              15.1   GOVERNING LAW AND JURISDICTION.  Licensor and Licensee

this transaction.  Subject to the provisions of Section 15.9, any action arising

            9.2.   TERMINATION.  This Agreement may be terminated at any time:

                   (a)  by the mutual consent of VCEU and ValueClick;

                   (b)  by ValueClick if there has been a breach of any

Agreement, which breach has not been cured within forty-five (45) days after
written notification thereof has been received by VCEU; or

                   (c)  by VCEU if:

                        (i)   there has been a breach of any representation

                        (ii)  a filing is made by or against (or an order for

purposes relating to the other party's internet advertising network.  Such
party shall cause those Representatives to observe the terms of this Section
10.1.  In the event that either party is requested pursuant to, or required
by, legal process to disclose any Confidential Information or any other
information concerning the other party, the party to which the request or
order is made shall provide the other party with prompt notice of such
request or requirement.

            10.2.  RETURN OF CONFIDENTIAL INFORMATION.  Upon termination of

representations and warranties contained in this Agreement shall survive
indefinitely.  Neither the period of survival nor the liability of either
party with respect to its obligations shall be reduced by an investigation
made at any time by or on behalf of the Indemnified Party. If written notice
of a claim has been given prior to the expiration of the applicable
representations and warranties, then the relevant representations and
warranties shall survive as to such claim, until such claim has been finally

<PAGE>

                   (a)  VCEU and its Affiliates, officers, directors,
employees, agents, successors and assigns (each a "VCEU Indemnified Party")
shall be indemnified and held harmless by ValueClick for any and all
liabilities, losses, damages, claims, costs and expenses, interest, awards,
judgments and penalties (including, without limitation, reasonable attorney's
and consultants' fees and expenses) actually suffered or incurred by them
(including, without limitation, any action brought or otherwise initiated by
any of them)(hereinafter a "Loss"), arising out of or resulting from:

                        (i)   the breach of any representation or warranty,
including the infringement of any Intellectual Property, made by ValueClick
contained in this Agreement; or

                        (ii)  the breach of any covenant or agreement made by
ValueClick contained in this Agreement.

                   (b)  ValueClick, its Affiliates, officers, directors,
employees, agents, successors and assigns (each a "ValueClick Indemnified
Party") shall be indemnified and held harmless by VCEU for any and all Losses
arising out of or resulting from the breach of any representation, warranty,
covenant or agreement by VCEU contained in this Agreement.

                   (c)  A VCEU Indemnified Party or a ValueClick Indemnified
Party, as the case may be (each an "Indemnified Party"), shall give the party
providing indemnification hereunder (the "Indemnifying Party") notice of any
matter that such Indemnified Party has determined has given or could give
rise to a right of indemnification under this Agreement, within 60 days of
such determination, stating the amount of the Loss, if known, and the method
of computation thereof, and containing a reference to the provisions of this
Agreement in respect of which such right of indemnification is claimed or
arises; provided, however, that the failure to provide such notice shall not
release the Indemnifying Party from any of its obligations under this Section
11, except to the extent the Indemnifying Party is materially prejudiced by
such failure and shall not relieve Indemnifying Party from any other
obligation or Liability that it may have to any Indemnified Party otherwise
than under this Section 11.  The obligations and liabilities of the
Indemnifying Party under this Section 11 with respect to Losses arising from
claims of any third party, which are subject to the indemnification provided
for in this Section 11 (the "Third Party Claims") shall be governed by and
contingent upon the following additional terms and conditions:  if an
Indemnified Party shall receive notice of any Third Party Claim, the
Indemnified Party shall give the Indemnifying Party notice of such Third
Party Claim within ten (10) days of the receipt by the Indemnified Party of
such notice; provided, however, that the failure to provide such notice shall
not release the Indemnifying Party from any of its obligations under this
Section 11, except to the extent the Indemnifying Party is materially
prejudiced by such failure and shall not relieve Indemnifying Party from any
other obligation or Liability that it may have to any Indemnified Party
otherwise than under this Section 11. If the Indemnifying Party acknowledges
in writing its obligation to indemnify the Indemnified Party hereunder
against any Losses that may result from such Third Party Claim, then the
Indemnifying Party shall be entitled to assume and control the defense of
such Third


                                      13

<PAGE>

Party Claim at its expense and through counsel of its choice if it
gives notice of its intention to do so to the Indemnified Party within ten
(10) days of the receipt of such notice from the Indemnified Party; provided,
however, that if there exists or is reasonably likely to exist one or more
legal defenses available to it that is in conflict with one or more defenses
available to the Indemnifying Party, or a conflict of interest that would
make it inappropriate in the judgment of the Indemnified Party, in its sole
and absolute discretion, for the same counsel to represent both the
Indemnified Party and the Indemnifying Party, the Indemnified Party shall be
entitled to retain its own counsel, in each jurisdiction for which the
Indemnified Party determines counsel is required, at the expense of the
Indemnifying Party.  In the event that the Indemnified Party is, directly or
indirectly, conducting the defense against any such Third Party Claim, the
Indemnifying Party shall cooperate with the Indemnified Party in such defense
and make availabe to the Indemnified Party, at the Indemnifying Party's
expense, all such witnesses, records, materials and information in the
Indemnifying Party's possession or under the Indemnifying Party's control
relating thereto as is reasonably required by the Indemnified Party.  No such
Third Party Claim may be settled by the Indemnifying Party without the prior
written consent of the Indemnified Party unless such settlement is for
monetary damages, exclusive of any injunctive or other equitable relief.

      12.   DISPUTE RESOLUTION.

            12.1.  NEGOTIATION.  The parties shall attempt in good faith to
resolve any dispute arising out of or relating to this Agreement promptly by
good faith negotiation.  Either party may give the other party written notice
of any dispute not resolved in the normal course of business.  Within twenty
(20) days after delivery of said notice, the parties shall meet at a mutually
acceptable time and place, and thereafter as often as they deem necessary, to
exchange relevant information and to attempt to resolve the dispute.  If the
matter has not been resolved within sixty (60) days of the disputing party's
notice, or if the parties fail to meet within twenty (20) days, either party
may initiate mediation of the controversy or claim as provided in Section
12.2 below.

            12.2.  MEDIATION.  If any dispute has not been resolved by
negotiation as provided in Section 12.1 hereof, the parties shall endeavor to
resolve the dispute by mediation under the then current Model Procedure for
Mediation of Business Disputes of the Center for Public Resources, Inc.
("CPR"), 366 Madison Avenue, New York, New York 10017.  The neutral third
party will be selected from the CPR Panel of Neutrals.  If the parties
encounter difficulty in agreeing on a neutral, they will seek the assistance
of CPR in the selection process.  Unless otherwise agreed by the parties, the
place of mediation shall be Los Angeles, California

            12.3.  ARBITRATION.  Any dispute that has not been resolved by
mediation, as provided in Section 12.2 hereof within sixty (60) days of the
initiation of such procedure, shall be finally settled by arbitration
conducted expeditiously in accordance with the CPR Rules for Non-Administered
Arbitration of Business Disputes by a sole arbitrator; provided, however,
that if one party has requested the other party to participate in a
non-binding dispute resolution procedure under Sections 12.1 or 12.2 hereof
and the other party has failed to participate therein, the other party may


                                      14

<PAGE>

initiate arbitration before expiration of the above time period.  The
arbitration shall be governed by the laws of the State of California, and
judgment upon the award rendered by the arbitrator may be entered by any
court having jurisdiction thereof.  The place of arbitration shall be Los
Angeles, California.  The arbitrator is not empowered to award damages in
excess of compensatory damages, which shall not include consequential
damages, and each party hereby irrevocably waives any damages in excess of
such compensatory damages.

            12.4.  COSTS.  The parties shall bear their respective costs in
connection with the dispute resolution procedures described in Sections 12.1,
12.2 and 12.3 hereof, except that the parties shall share equally the fees
and expenses of any neutral third party or arbitrator and the costs of any
facility used in connection with such dispute resolution procedures.

            12.5.  REPRESENTATION BY COUNSEL.  With respect to the
non-binding procedures provided in Sections 12.1 or 12.2 hereof, if a
negotiator intends to be accompanied at a meeting by an attorney, the other
negotiator shall be given at least three (3) working days' notice of such
intention and may also be accompanied by an attorney.  All negotiations
relating to any non-litigated procedure provided herein are confidential and
shall be treated as compromise and settlement negotiations for purposes of
the rules of evidence of all applicable jurisdictions.

                                DESCRIPTION OF POD

The POD includes the necessary hardware and software to manage the VCEU
advertising network. In Europe, the POD will be similar in function to the
POD currently installed and running the ValueClick advertising network. This
includes, but is not limited to, the following:

Hardware
      5 slave servers
      1 "Pollux" system (main software system)
      2  Equalizers
      1  Switch

Software and OS
      FreeBSD for all servers
      ValueClick proprietary banner server engine
      ValueClick proprietary administration software
      Misc. software, e.g., SSH and Verisign for secure transactions

The POD will include all equipment and software anticipated to handle the
startup  workload. In addition, hardware and software will be installed
within the original POD to accommodate the growth that is expected through
the first several months of business. This will allow both sides to focus on
growing the business from a customer perspective, rather than being slowed
down by the continual adding of small increments of equipment.

                                    FORM OF
                    EMPLOYEE CONFIDENTIALITY, NONCOMPETITION
                             AND INVENTION AGREEMENT

     This EMPLOYEE CONFIDENTIALITY, NONCOMPETITION AND INVENTION AGREEMENT is
made as of ____________, 1999, by and between ValueClick, Inc., a Delaware
corporation ("the Company"), and the undersigned employee (the "Employee").

     As a result of his or her employment by the Company, the Employee has
had or will have access to and has or will become acquainted with various
trade secrets and other proprietary and confidential information and property
of the Company, the disclosure or use of which for any purposes other than in
the Company's business would unreasonably and unfairly impair the Company's
ability to conduct its business profitably.

     THEREFORE, as a condition of and in consideration of the Company's
employment or continuation of employment of the Employee, the Employee agrees
with the Company as follows:

     1.   CERTAIN DEFINITIONS. For purposes of this Agreement, the terms
defined below have the meanings indicated.

          1.1       "AFFILIATE". "Affiliate" means and includes any of the
Company's subsidiaries (whenever formed or acquired), and any corporation,
limited liability company, partnership, joint venture, association or other
entity in which the Company owns or comes to own more than twenty percent of
the voting stock or other ownership interest or which owns or

                                       1

<PAGE>

comes to own twenty percent or more of the Company's outstanding common
stock, and any of the Company's clients, customers, licensees, licensors,
franchisees and franchisors.

          1.2       "CONFIDENTIAL MATTER".  "Confidential Matter" means and
includes the following:

         Various financial and operating data and other proprietary and
         confidential information of the Company consisting of marketing data;
         equipment; documents; files; electronically recordable data or
         concepts; computer software and hardware; inventions; improvements;
         books; papers; compilations of information; records; specifications;
         names, addresses, names of agents and employees, buying habits and
         practices of existing and potential clients, customers and other
         Affiliates; names, marketing methods, practices and related information
         regarding the Company's existing and potential joint venture partners,
         licensees, licensors, vendors, suppliers and distributors; costs of
         materials; prices the Company obtains or has obtained or at which it
         sells, has sold or intends to sell its products or services; lists or
         other written records used in the Company's business; information
         regarding the Company's financial condition; compensation paid to the
         Company's consultants and employees and other terms of employment; and
         any of the foregoing that may have been or may be conceived,
         originated, discovered or developed by the Company or the Employee or
         any other employees or consultants of the Company while employed or
         engaged by the Company or on the basis of or using any Confidential
         Matter.

                                       2

<PAGE>

All of the foregoing are owned and held in strict confidence by the Company
or by Affiliates to which the Company has a duty of confidentiality.
Nevertheless, "Confidential Matter" excludes any of the foregoing that has
entered the public domain through no fault of the Employee, that an
authorized executive officer of the Company has authorized for public
dissemination, that was known to or possessed by the Employee prior to his or
her employment by the Company and other than through disclosure or delivery
by the Company, or that was learned or obtained by the Employee from sources
having no duty of confidentiality to the Company that were or are unconnected
with and unrelated to his or her employment by the Company.

     2.   NONDISCLOSURE, COMPETITION, SOLICITATION, PROPERTY.

          2.1       NONDISCLOSURE. The Employee acknowledges and agrees that,
as an employee of the Company, he or she has had or will have access to and
has or will become acquainted with Confidential Matter, all of which the
Employee will regard and protect as trade secrets owned by the Company and
all of which are used or contemplated to be used in the Company's business.
The Employee represents, warrants and agrees that, except as required by the
Company in the course of his or her employment with the Company, he or she
will not at any time, whether during or after his or her employment by the
Company, directly or indirectly, use or permit others to use, or disclose or
communicate to any person or entity, any Confidential Matter, without the
prior written consent of an executive officer of the Company in the
particular case.

          2.2       COMPETITION, SOLICITATION. The Employee further
acknowledges and agrees that, as an employee of the Company he or she has
participated or will participate in important aspects of the Company's
research, development, creative work, planning, operations

                                       3

<PAGE>

and other activities, and that the conduct by him or her of any business or
activity directly or indirectly competing with the Company's business
necessarily would constitute trading on the Company's good will and
reputation developed through the Company's expenditure of very substantial
efforts and moneys, would involve the use by the Employee of Confidential
Matter and would unreasonably and unfairly impair the Company's ability to
conduct its business profitably.

                  The Employee  therefore  further  acknowledges and agrees
that he or she will not at any time during his or her employment with the
Company directly or indirectly own an interest in, join, operate, control,
participate in or be connected, as an officer, director, manager, employee,
agent, independent contractor, consultant, member, partner, shareholder
(except as a shareholder of a corporation in the management and affairs of
which the Employee has no control and which is the issuer of shares that are
actively traded in a national securities market) or principal, with any
corporation, limited liability company, partnership, joint venture,
proprietorship, association or other entity or person engaged in developing,
producing, designing, providing, soliciting orders for, selling, distributing
or marketing products or services that directly or indirectly compete with
the Company's products, services or other business, in any markets in which
the Company is now doing business, contemplates doing business or does
business during his or her employment, or directly or indirectly take or
permit any action in preparation to do any of the foregoing. As further
protection for the Confidential Matter, the Employee agrees that he or she
will not, directly or indirectly, and whether or not for compensation, divert
or attempt to divert from the Company any business in which the Company is
engaged or contemplates engaging or induce or attempt to induce any employee
of the Company to leave the Company's employ.

                                       4

<PAGE>

           2.3      PROPERTY. The Employee agrees that he or she will not
make or retain any originals, copies or reproductions of or excerpts from any
of the Confidential Matter for his or her use or the use of others and, on
request by the Company or on termination of the Employee's employment with
the Company, the Employee will deliver to the Company all tangible property
that is or embodies any of the Confidential Matter, whether prepared or
developed by or with the assistance of the Employee or otherwise coming into
his or her possession, control or knowledge.

          2.4       LEGAL DUTIES. The Employee acknowledges and agrees that
his or her agreements herein are intended to implement certain of the
Employee's duties under Federal and state laws, such as California Labor Code
section 2860, which provides:

         "Everything which an employee acquires by virtue of his employment,
         except the compensation which is due to him from his employer, belongs
         to the employer, whether acquired lawfully or unlawfully, or during or
         after the expiration of the term of his employment."

This Agreement shall not be interpreted or construed as limiting the Employee's
obligations or the Company's rights under any of such laws.

          2.5       NONDISCLOSURE TO THE COMPANY. The Employee further
represents and warrants that the Employee has not disclosed and will not
disclose to the Company or any Affiliate any trade secrets or other
proprietary or confidential information that may not lawfully be so disclosed
by the Employee, by virtue of the ownership of the same by another person or
entity or otherwise.

                                       5

<PAGE>

    3.    INVENTIONS, DESIGNS AND PATENTS.

          3.1       DISCLOSURE AND ASSIGNMENT OF INVENTIONS. The Employee
agrees that he or she will promptly and fully disclose to the Company, and
the Company agrees to keep confidential, all inventions, designs, creations,
processes, technical or other developments, improvements, ideas and
discoveries (collectively, "Inventions"), whether patentable or not, of which
the Employee obtains knowledge or information during his or her employment
with the Company and for a period of one year thereafter and which relate to
the existing or contemplated products, services or business of or to any
research or experimental, developmental or creative work carried on or
contemplated by the Company, whether or not conceived, originated, made,
developed or reduced to practice by the Employee alone or with others during
regular working hours or at other times. All Inventions are and shall remain
the exclusive property of the Company. The Employee agrees that he or she
will assign, and hereby does assign, to the Company or its designee, all of
the Employee's right, title and interest in and to all Inventions, whether
patentable or not, conceived, originated, made, developed or reduced to
practice by the Employee, alone or with others, while he or she is an
employee with the Company.

          3.2       COOPERATION. The Employee agrees to assist the Company to
obtain any and all patents, copyrights, trademarks and service marks relating
to Inventions and to execute all documents and do all things necessary to
obtain letters patent and copyright, trademark and service mark registrations
therefor, to vest the Company or its designee with full and exclusive title
thereto and to protect the same against infringement by others, all as and to
the extent the Company may request and at the Company's expense, for no
consideration to the Employee other than the Employee's salary or wages.

                                       6

<PAGE>

          3.3       EXCEPTIONS. Sections 3.1 and 3.2 shall not, however,
apply to an Invention developed entirely on the Employee's own time without
using the Company's or any Affiliate's equipment, supplies, facilities or
trade secret information except for those Inventions that either (a) relate
at the time of conception or reduction to practice of the Invention to the
Company's business or demonstrably anticipated research or development of the
Company, or (b) result from any work performed by the Employee for the
Company. The Employee acknowledges and agrees that the preceding sentence
constitutes the notification required by California Labor Code section 2872.
The Employee has listed on the Attachment to this Agreement, which the
Company agrees to keep confidential, all unpatented Inventions owned,
conceived, originated, made, developed or reduced to practice by the Employee
(whether or not prior to the Employee's employment with the Company)
qualifying for the exception in the first sentence of this section 3.3.

     4.   TRADE SECRETS OF THIRD PARTIES. The Employee acknowledges and
understands that, in dealing with existing and potential Affiliates,
suppliers, contracting parties and other third parties with which the Company
has business relations or potential business relations, the Company
frequently receives confidential and proprietary information and materials
from such third parties subject to the Company's understanding that the
Company will maintain the confidentiality thereof and will require its
employees and consultants to do so. The Employee agrees to treat all such
information and materials as Confidential Matter subject to this Agreement.

     5.   INJUNCTIVE RELIEF. The Employee acknowledges and agrees that his or
her failure to perform any of his or her covenants in this Agreement would
cause irreparable injury to the

                                       7

<PAGE>

Company and cause damages to the Company that would be difficult or
impossible to ascertain or quantify. Accordingly, without limiting any
remedies that may be available with respect to any breach of this Agreement,
the Employee consents to the entry of an injunction to restrain any breach of
this Agreement.

     6.   SEVERABILITY. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other
provision hereof.

     7.   ATTORNEYS' FEES. If suit is brought to enforce or interpret this
Agreement, the prevailing party shall be entitled to recover as an element of
costs of suit, and not as damages, reasonable attorneys' fees and expenses
and all expert witnesses' fees and expenses incurred by the prevailing party.
In such event, the "prevailing party" shall be the party that is entitled to
recover costs of suit, whether or not the suit proceeds to final judgment,
the party not entitled to recover costs shall not recover attorneys' or
expert witnesses' fees or expenses and no sum for attorneys' and expert
witnesses' fees and expenses shall be counted in calculating the amount of a
judgment for purposes of determining whether a party is entitled to recover
costs or attorneys' or expert witnesses' fees or expenses.

     8.   HEADINGS. The section headings in this Agreement are for
convenience of reference only and are not part of this Agreement.

     9.   NOTICES. Any notice, consent or other communication to be given
under or in connection with this Agreement shall be in writing and shall be
deemed duly given and received when delivered personally, when transmitted by
facsimile if receipt is acknowledged by the addressee, one day after being
deposited for next-day delivery with a nationally recognized

                                       8

<PAGE>

overnight delivery service or three days after being mailed by first class
mail, charges or postage prepaid, properly addressed, if to the Company, at
6450 Via Real, Carpinteria, California 93013 (Facsimile number: (805)
566-0190), and, if to the Employee, at his or her address or facsimile number
appearing on the records of the Company. Either the Company or the Employee
may change its or his or her address for this purpose from time to time by
notice to the other.

     10.  SUCCESSORS. This Agreement shall inure to the benefit of and bind
the Company and the Employee and their respective successors, assigns, heirs,
legatees, devisees and personal representatives.

     11.  ENTIRE AGREEMENT. This Agreement contains the entire agreement of
the Company and the Employee and supersedes all prior or contemporaneous
negotiations, correspondence, understandings and agreements, whether written
or oral, between them, with respect to the subject matter hereof.

     12.  SURVIVAL. All agreements, representations, warranties and
acknowledgments herein shall survive any termination of the Employee's
employment with the Company for any reason.

     13.  THE COMPANY'S RIGHT TO TERMINATE. Nothing herein shall be
interpreted to impair or otherwise affect the right and power of the Company
to terminate its employment of the Employee, which is at will.

                        MUTUAL NONDISCLOSURE AGREEMENT

     Each undersigned party (which together with their subsidiaries and
affiliated entities is referred to herein as the "Receiving Party")
understands that the other party (which together with their subsidiaries and
affiliated entities is referred to herein as the "Disclosing Party") has
disclosed or may disclose information relating to the Disclosing Party's
business (including, without limitation, its properties, employees, finances,
businesses and operations), which to the extent previously, presently, or
subsequently disclosed to the Receiving Party, as well as the Receiving
Party's analyses, conclusions and evaluations thereof (whether in written or
electronic form), is hereinafter referred to as "Proprietary Information" of
the Disclosing Party.

     In consideration of the parties' discussions in connection with a
proposed transaction between the parties (the "Transaction") and any access
the Receiving Party may have to Proprietary Information of the Disclosing
Party, the Receiving Party hereby agrees as follows:

     1.   All administrative, technical, financial, trade-secret,
manufacturing, or other confidential information shall be deemed to be
"Proprietary Information" for purposes of this Agreement. The fact that
Proprietary Information does not carry a proprietary legend, or is
transmitted verbally, shall not act as a waiver to deprive such information
from protection under this Agreement.

     2.   The Receiving Party agrees (i) to hold the Disclosing Party's
Proprietary Information delivered in accordance with paragraph 1 above (the
"Confidential Information") in strict confidence and to take all reasonable
precautions to protect the Confidential Information (including, without
limitation, all precautions the Receiving Party employs with respect to its
confidential materials), (ii) not to divulge any such Confidential
Information or any information derived therefrom to any third person
(including, but not limited to, any affiliated person or entity), except to
the Receiving Party's attorneys, accountants or professional advisors on a
"need to know" basis, (iii) not to make any use whatsoever at any time of
such Confidential Information except to evaluate internally, or to evaluate
with the parties set forth in (ii) above, whether to enter into an agreement
with the Disclosing Party relating to the Transaction, (iv) not to remove or
export from the United States or re-export any such Confidential Information
or any direct product thereof to Afghanistan, the Peoples' Republic of China
or any Group Q, S, W, Y or Z country (as specified in Supplement No. 1 to
Section 770 of the U.S. Export Administration Regulations, or a successor
thereto) or otherwise except in compliance with and with all licenses and
approvals required under applicable export laws and regulations, including
without limitation, those of the U.S. Department of Commerce, and (v) not to
copy or reverse engineer any such Confidential Information. Any employee
given access to any such Confidential Information by the Receiving Party must
have a legitimate "need to know" and shall be similarly bound in writing.
Without granting any right or license, the Disclosing Party agrees that the
foregoing clauses (i), (ii), (iii) and (v) shall not apply with respect to
any Confidential that the Receiving Party can document (a) is or, through no
improper action or inaction by the Receiving Party or any affiliate, agent,
consultant or employee, is made generally available to the public, or (b) was
in its possession or known by it prior to receipt from the Disclosing Party,
or (c) was rightfully

<PAGE>

disclosed to it by a third party, provided the Receiving Party complies with
any restrictions imposed by such third party, or (d) was independently
developed without use of any Confidential Information of the Disclosing
Party. For purposes of the immediately preceding sentence, the terms
"availability," "possession," "disclosure," "development" or "knowledge" of
information combined, synthesized or used by the Disclosing Party in a
particular manner are meant to incorporate the various pieces of information
as they are combined, synthesized or used. Such terms are not meant to
include the availability, possession, disclosure, development or knowledge of
various pieces of information that are not so combined, synthesized or used.
The Receiving Party may make disclosures required by law (including, without
limitation, the disclosure requirements of the Federal securities laws of the
United States) or court order, PROVIDED that the Receiving Party uses
reasonable efforts to limit any such disclosure and to obtain confidential
treatment or a protective order and has allowed the Disclosing Party to
participate in attempting to limit such disclosure or to seek confidential
treatment. Nothing contained in this Agreement shall be construed as granting
or conferring any rights by license or otherwise in any Proprietary
Information disclosed.

     3.   Immediately upon (i) the decision by either party not to enter into
the Transaction contemplated hereby, or (ii) a request by the Disclosing
Party at any time (which will be effective if actually received or three days
after mailed first class postage prepaid to the Receiving Party's address
set forth herein), the Receiving Party will turn over to the Disclosing Party
all Confidential Information of the Disclosing Party and all documents or
media containing any such Confidential Information and any and all copies or
extracts thereof. In addition, the Receiving Party shall provide the
Disclosing Party with written notice that it has returned all of the
Disclosing Party's Confidential Information and all copies or extracts
thereof. The Receiving Party understands that nothing herein (a) requires
the disclosure of any Confidential Information of the Disclosing Party, which
shall be disclosed if at all solely at the option of the Disclosing Party (in
particular, but without limitation, any disclosure is subject to compliance
with export control laws and regulations), or (b) requires the Disclosing
Party to proceed with any proposed transaction or relationship in connection
with which Confidential Information may be disclosed.

     4.   Except to the extent required by law, neither party shall disclose
the existence or subject matter of the negotiations or business relationship
contemplated by this Agreement.

     5.   Notwithstanding anything in this letter agreement to the contrary,
the Disclosing Party hereby represents and warrants that such party may
rightfully disclose or make available the Proprietary Information to the
Receiving Party without the violation of any contractual, legal, fiduciary or
other obligation to any person, and the Disclosing Party shall indemnify and
hold harmless in full the Receiving Party against any and all damages, costs
and expenses of any nature whatsoever (including, without limitation,
reasonable attorneys' fees) incurred by the Receiving Party in connection with
the breach of such representation and warranty.

     6.   Subject to the terms and conditions of a definitive agreement
regarding the Transaction and without the prejudice thereto, each party
hereto acknowledges that neither it nor any of its officers, directors,
employees or agents makes any express or implied representation or

warranty as to the completeness of the Proprietary Information. The Receiving
Party shall not be entitled to rely on the completeness of any Proprietary
Information, but shall be entitled to rely solely on such representations and
warranties regarding the completeness of the Proprietary Information as may
be made to it in any definitive agreement relating to the Transaction,
subject to the terms and conditions of such agreement.

     7.   Each party is aware, and will advise its representatives and agents
who are informed of the matters that are the subject to this letter
agreement, of the restrictions imposed by the United States securities laws
on the purchase or sale of securities by any persons who has received
material, non-public information from the issuer of such securities and on
the communication of such information to any other person when it is
reasonably foreseeable that such other person is likely to purchase or sell

months of the date of this Agreement. However, the obligations hereunder with
respect to any disclosure made within that period will continue thereafter in

     9.   The Receiving Party acknowledges and agrees that due to the unique
nature of the Disclosing Party's Confidential Information, there can be no
adequate remedy at law for any breach of its obligations hereunder, 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 appropriate equitable
relief in addition to whatever remedies it might have at law and to be
indemnified by the Receiving Party from any loss or harm, including, without
limitation, attorney's fees, in connection with any breach or enforcement of
the Receiving Party's obligations hereunder or the unauthorized use or
release of any such Confidential Information as set forth herein. The
Receiving Party will notify the Disclosing Party in writing immediately upon
the occurrence of any such unauthorized release or other breach of which it
is aware. In the event that any of the provisions of this Agreement shall be
held by a court or other tribunal of competent jurisdiction to be illegal,
invalid or unenforceable, such provisions shall be limited or eliminated to
the minimum extent necessary so that this Agreement shall otherwise remain in
full force and effect.

     10.  This Agreement shall be governed by the law of the State of
California without regard to the conflicts of law provisions thereof. This
Agreement supersedes all prior discussions and writings and constitutes the
entire agreement between the parties with respect to the subject matter
hereof. The prevailing party in any action to enforce this Agreement shall
be entitled to costs and attorneys' fees. No waiver or modification of this
Agreement will be binding upon either party unless made in writing and signed
by a duly authorized representative of such party and no failure or delay in
enforcing any right will be deemed a waiver.

         obligations which have arisen prior to the termination of this
         Sublease, Sublessee does hereby expressly assume and agree to perform

<PAGE>

8.   ASSIGNMENT OF SUBLEASE AND DEFAULT.

8.1      Sublessor hereby assigns and transfers to Master Lessor the
         Sublessor's interest in this Sublease, subject however to the
         provisions of Paragraph 8.2 hereof.

8.2      Master Lessor, by executing this document, agrees that until a Default
         shall occur in the performance of Sublessor's obligations under the
         Master Lease, that Sublessor may receive, collect and enjoy the Rent
         accruing under this Sublease. However, if Sublessor shall Default in
         the performance of its obligations to Master Lessor then Master Lessor
         may, at its option, receive and collect, directly from Sublessee, all
         Rent owing and to be owed under this Sublease. Master Lessor shall not,
         by reason of this assignment of the Sublease not by reason of the
         collection of the Rent from the Sublessee, be deemed liable to
         Sublessee for any failure of the Sublessor to perform and comply with
         Sublessor's Remaining Obligations.

8.3      Sublessor hereby irrevocably authorizes and directs Sublessee upon
         receipt of any written notice from the Master Lessor stating that a
         Default exists in the performance of Sublessor's obligations under the
         Master Lease, to pay to Master Lessor the Rent due and to become due
         under the Sublease. Sublessor agrees that Sublessee shall have the
         right to rely upon any such statement and request from mater Lessor,
         and that Sublessee shall pay such Rent to Master Lessor without any
         obligation or right to inquire as to whether such Default exists and
         notwithstanding any notice from or claim from Sublessor to the contrary
         and Sublessor shall have no right or claim against Sublessee for any
         such Rent so paid by Sublessee.

8.4      No changes or modifications shall be made to this Sublease without
         the consent of Master Lessor.

9.   CONSENT OF MASTER LESSOR.

9.1      In the event that the Master Lease requires that Sublessor obtain the
         consent of Master Lessor to any subletting by Sublessor then, this
         Sublease shall not be effective unless, within then days of the date
         hereof, master Lessor signs this Sublease thereby giving its consent to
         this Subletting.

9.2      In the event that the obligations of the Sublessor under the Master
         Lease have been guaranteed by third parties then neither this Sublease,
         nor the Master Lessor's consent, shall be effective unless, within 10
         days of the date hereof, said guarantors sign this Sublease thereby
         giving their consent to this sublease.

9.3      In the event that Master Lessor does give such consent then:
         (a)  Such consent shall not release Sublessor of its obligations or
              alter the primary liability of Sublessor to pay the Rent and
              perform and comply with all the obligations of Sublessor to be
              performed under the Master Lease.
         (b)  The acceptance of Rent by Master Lessor from Sublessee or
              anyone else liable under the master Lease shall not be deemed a
              waiver by Master Lessor of any provisions of the Master Lease.
         (c)  The consent to this Sublease shall not constitute a consent to
              any subsequent subletting or assignment.
         (d)  In the event of any Default of Sublessor under the Master Lease,
              Master Lessor may proceed directly against Sublessor, any
              guarantors or anyone else liable under the Master Lease or this
              Sublease without first exhausting Master Lessor's remedies against
              any other person or entity liable thereon to Master Lessor.
         (e)  Master lessor may consent to subsequent sublettings and
              assignments of the Master Lease or this Sublease or any amendments
              or modifications thereto without notifying Sublessor or any one
              else liable under the Master Lease and without obtaining their
              consent and such action shall not relieve such persons from
              liability.
         (f)  In the event that Sublessor shall Default in its obligations under
              the Master Lease, then Master Lessor, at its option and without
              being obligated to do so, may require Sublessee to attorn to
              Master Lessor in which event Master Lessor shall undertake the
              obligations of Sublessor under

<PAGE>

              this Sublease from the time of the exercise of said option to
              termination of this Sublease but Master Lessor shall not be
              liable for any prepaid Rent nor any Security deposit paid by
              Sublessee, not shall Master Lessor be liable for any other
              Defaults of the Sublessor under the Sublease.

9.4      The signatures of the Master Lessor and any Guarantors of Sublessor
         at the end of this document shall constitute their consent to the
         terms of the Sublease.

9.5      Master Lessor acknowledges that, to the best of Master Lessor's
         knowledge, no Default presently exists under the Master Lease of
         obligations to be performed by Sublessor and that the Master Lease is
         in full force and effect.

9.6      In the event that Sublessor Defaults under its obligations to be
         performed under the Master Lease by Sublessor, Master Lessor agrees to
         deliver to Sublessee a copy of any such notice of default. Sublessee
         shall have the right to cure any Default of Sublessor described in any
         notice of default within ten days after service of such notice of
         default on Sublessee. If such Default is cured by Sublessee then
         Sublessee shall have the right of reimbursement and offset from and
         against Sublessor.

         transaction.

         substantially similar thereto, either to extend the term of this

              (iii)  The cost of the premiums for the liability and property
                     insurance policies to be maintained by Lessor under
                     paragraph 8 hereof;
              (iv)   The amount of the real property tax to be paid by Lessor
                     under paragraph 10.1 hereof;
              (v)    The cost of water, gas and electricity to service the
                     Common Areas.
       (c)    The inclusion of the improvement, facilities and services set
              forth in paragraph 4.2 (b)(i) of the definition of Operating
              Expenses shall not be deemed to impose an obligation upon Lessor
              to either have said improvements or facilities or to provide those
              services unless the Industrial Center already has the same, Lessor
              already provides the services, or Lessor has agreed elsewhere in
              this Lease to provide the same or some of them.
       (d)    Lessee's Share of Operating Expenses shall be payable by Lessee
              within ten (10) days after a reasonably detailed statement of
              actual expenses is presented to Lessee by Lessor.  At lessor's
              option, however, an amount may be estimated by Lessor from time to
              time of Lessee's Share of annual Operating Expenses and the same
              shall be payable monthly or quarterly, as Lessor shall designate,
              during each twelve-month period of the Lease term, on the same day
              as the Base Rent is due hereunder.  In the event that Lessee pays
              Lessor's estimate of Lessee's Share of Operating Expenses as
              aforesaid, Lessor shall deliver to Lessee within sixty (60) days
              after the expiration of each calendar year a reasonably detailed
              statement showing Lessee's Share of the actual Operating Expenses
              incurred during the preceding year.  If Lessee's payments under
              this paragraph 4.2(d) during said preceding year exceed Lessee's
              Share as indicated on said statement, Lessee shall be entitled to
              credit the amount of such overpayment against Lessee's Share of
              Operating Expenses next falling due.  If Lessee's payments under
              this paragraph during said preceding year were less than Lessee's
              Share as indicated on said statement, Lessee shall pay to Lessor
              the amount of the deficiency within ten (10) days after delivery
              by Lessor to Lessee of said statement.

5.     SECURITY DEPOSIT.  Lessee shall deposit with Lessor upon execution hereof
       $3,575.00 as security for Lessee's faithful performance of Lessee's
       obligations hereunder.  If Lessee fails to pay rent or other charges due
       hereunder, or otherwise defaults with respect to any provision of this
       Lease.  Lessor may use, apply or retain all or any portion of said
       deposit for the payment of any rent or other charge in default or for the
       payment of any other sum to which Lessor may become

<PAGE>

       obligated by reason of Lessee's default, or to compensate Lessor for any
       loss or damage which Lessor may suffer thereby.  If Lessor so uses or
       applies all or any portion of said deposit.  Lessee shall within
       ten (10) days after written demand therefor deposit cash with Lessor in
       an amount sufficient to restore said deposit to the full amount then
       required of Lessee.  If the monthly rent shall from time to time,
       increase during the term of this Lease, Lessee shall, at the time of such
       increase, deposit with Lessor additional money as a security deposit so
       that the total amount of the security deposit held by Lessor shall at all
       times bear the same proportion to the then current Base Rent as the
       initial security deposit bears to the initial Base Rent set forth in
       paragraph 4.  Lessor shall not be required to keep said security deposit
       separate from its general accounts.  If Lessee performs all of Lessee's
       obligations hereunder, said deposit, or so much thereof as has not
       theretofore been applied by Lessor, shall be returned, without payment of
       interest or other increment for its use, to Lessee (or, at Lessor's
       option, to the last assignee, if any, of Lessee's interest hereunder) at
       the expiration of the term hereof, and after Lessee has vacated the
       Premises.  No trust relationship is created herein between Lessor and
       Lessee with respect to said Security Deposit.

6.     USE.

6.1    USE.  The Premises shall be used and occupied only for GENERAL OFFICE
       USE AND FOR NO OTHER USE WITHOUT LESSOR'S PRIOR written consent. See
       Addendum for additional terms.

6.2    COMPLIANCE WITH LAW.

       (a)    Lessor warrants to Lessee that the Premises, in the state existing
              on the date that the Lease term commences, but without regard to
              the use for which Lessee will occupy the Premises, does not
              violate any covenants or restrictions of record, or any applicable
              building code, regulation or ordinance in effect on such Lease
              term commencement date.  In the event it is determined that this
              warranty has been violated, then it shall be the obligation of the
              Lessor, after written notice from Lessee, to promptly, at Lessor's
              sole cost an expense, rectify any such violation.  In the event
              Lessee does not give to Lessor written notice of the violation of
              this warranty within six months from the date that the Lease term
              commences, the correction of same shall be the obligation of the
              Lessee at Lessee's sole cost.  The warranty contained in this
              paragraph 6.2(a) shall be of no force or effect if, prior to the
              date of this Lease, Lessee was an owner or occupant of the
              Premises and, in such event, Lessee shall correct any such
              violation at Lessee's sole cost.

       (b)    Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's
              expense, promptly comply with all applicable statutes, ordinances,
              rules, regulations, orders, covenants and restrictions of record,
              and requirements of any fire insurance underwriters or rating
              bureaus, now in effect or which may hereafter come into effect,
              whether or not they reflect a change in policy from that now
              existing, during the term or any part of the term or which may
              hereafter come into effect, whether or not they reflect a change
              in policy from that now existing, during the term or any part of
              the term hereof, relating in any manner to the Premises and the
              occupation and use by Lessee of the Premises and of the Common
              Areas.  Lessee shall not use nor permit the use of the Premises or
              the Common Areas in any manner that will tend to create waste or a
              nuisance or shall tend to disturb other occupants of the
              Industrial Center.


6.3    CONDITION OF PREMISES

       (a)    Lessor shall deliver the Premises to Lessee clean and free of
              debris on the Lease commencement date (unless Lessee is already in
              possession) and Lessor warrants to Lessee that the plumbing,
              lighting, air conditioning, heating, and loading doors in the
              Premises shall be in good operating condition on the Lease
              commencement date.  In the event that it is determined that this
              warranty has been violated, then it shall be the obligation of
              Lessor, after receipt of written notice from Lessee setting forth
              with specificity the nature of the violation, to promptly, at
              Lessor's sole cost, rectify such violation.  Lessee's failure to
              give such written

<PAGE>

              notice to Lessors within thirty (30) days after the Lease
              commencement date shall cause the conclusive presumption
              that Lessor has complied with all of Lessor's obligations
              hereunder.  The warranty contained in this paragraph 6.3(a) shall
              be of no force or effect if prior to the date of this Lease,
              Lessee was an owner or occupant of the Premises.  See Addendum.

       (b)    Except as otherwise provided in this Lease, Lessee hereby accepts
              the Premises in their condition existing as of the Lease
              commencement date or the date that Lessee takes possession of the
              Premises, whichever is earlier, subject to all applicable zoning,
              municipal, county and state laws, ordinances and regulations
              governing and regulating the use of the Premises, and any
              covenants or restrictions of record, and accepts this Lease
              subject thereto and to all matters disclosed thereby and by any
              exhibits attached hereto.  Lessee acknowledges that neither Lessor
              nor Lessor's agent has made any representation or warranty as to
              the present or future suitability of the Premises for the conduct
              of Lessee's business.

7.     MAINTENANCE, REPAIRS, ALTERATIONS AND COMMON AREA SERVICES.

7.1    LESSOR'S OBLIGATIONS.  Subject to the provisions of  Paragraphs 4.2
       (Operating Expenses). 6 (Use), 7.2 (Lessee's Obligations) and 9 (Damage
       or Destruction) and except for damage caused by any negligent or
       intentional act or omission of Lessee, Lessee's employees, suppliers,
       shippers, customers, or invitees, in which event Lessee shall repair the
       damage, Lessor, at Lessor's expense, subject to reimbursement pursuant to
       paragraph 4.2 shall keep in good condition and repair the foundations,
       exterior walls, structural condition of interior bearing walls, and roof
       of the Premises, as well as the parking lots, walkways, driveways,
       landscaping, fences, signs and utility installations of the Common Areas
       and all parts thereof, as well as providing the services for which there
       is an Operating expense pursuant to paragraph 4.2.  Lessor shall not,
       however, be obligated to paint the exterior or interior surface of
       exterior walls, nor shall Lessor be required to maintain, repair or
       replace windows, doors or plate glass of the Premises.  Lessor shall have
       no obligation to make repairs under this paragraph 7.1 until a reasonable
       time after receipt of written notice from Lessee of the need for such
       repairs.  Lessee expressly waives the benefits of any statute now or
       hereafter in effect which would otherwise afford Lessee the right to make
       repairs at Lessor's expense or to terminate this Lease because of
       Lessor's failure to keep the Premises in good order, condition and
       repair.  Lessor shall not be liable for damages or loss of any kind or
       nature by reason of Lessor's failure to furnish any Common Area Services
       when such failure is caused by accident, breakage, repairs, strikes,
       lockout, or other labor disturbances or disputes of any character, or by
       any other cause beyond the reasonable control of Lessor.

7.2    LESSEE'S OBLIGATIONS.

       (a)    Subject to the provisions of paragraphs 6 (Use), 7.1 (Lessor's
              Obligations), and 9 (Damage or Destruction), Lessee, at Lessee's
              expense, shall keep in good order, condition and repair the
              Premises and every part thereof (whether or not the damaged
              portion of the Premises of the means of repairing the same are
              reasonably or readily accessable to Lessee) including, without
              limiting the generality of the foregoing, all plumbing, heating,
              ventilating and air conditioning systems (Lessee shall procure and
              maintain, at Lessee's expense, a ventilating and air conditioning
              system maintenance contract), electrical and lighting facilities
              and equipment within the Premises, fixtures, interior walls and
              interior surfaces of exterior walls, ceilings, windows, doors,
              plate glass, and skylights located within the Premises.  Lessor
              reserves the right to procure and maintain the ventilating and air
              conditioning system maintenance contract and if Lessor so elects,
              Lessee shall reimburse Lessor, upon demand, for the cost thereof.
              Lessee shall be responsible for clean-up of all hazardous waste
              occurring in or about the Premises.

       (b)    If Lessee fails to perform Lessee's obligations under this
              paragraph 7.2 or under any other paragraph of this Lease, Lessor
              may enter upon the Premises after ten (10) days'

<PAGE>


              prior written notice to Lessee (except in the case of emergency,
              in which no notice shall be required), perform such obligations
              on Lessee's behalf and put the Premises in good order, condition
              and repair, and the cost thereof together with interest thereon at
              the maximum rate then allowable by law shall be due and payable as
              additional rent to Lessor together with Lessee's next Base Rent
              installment.

       (c)    On the last day of the term hereof, or on any sooner termination,
              Lessee shall surrender the Premises to Lessor in the same
              condition as received, ordinary wear and tear excepted, clean and
              free of debris.  Any damage or deterioration of the Premises shall
              not be deemed ordinary wear and tear if the same could have been
              prevented by good maintenance practices.  Lessee shall repair any
              damage to the Premises occasioned by the installation or removal
              of Lessee's trade fixtures, alterations, furnishings and
              equipment.  Notwithstanding anything to the contrary otherwise
              stated in this Lease, Lessee shall leave the air lines, power
              panels, electrical distribution systems, lighting fixtures, space
              heaters, air conditioning, plumbing and fencing on the Premises in
              good operating condition.

7.3     ALTERATIONS AND ADDITIONS.

       (a)    Lessee shall not, without Lessor's prior written consent make any
              alteration, improvement, additions, or Utility Installations in,
              on or about the premises, or the Industrial Center, except for
              nonstructural alterations to the Premises not exceeding $2,500 in
              cumulative costs, during the term of this Lease.  In any event,
              whether or not in excess of $2,500 in cumulative cost, Lessee
              shall make no change or alteration to the exterior of the Premises
              nor the exterior of the Building not the Industrial Center without
              Lessor's prior written consent.  As used in this paragraph 7.3 the
              term "Utility Installation" shall mean carpeting, window
              coverings, air lines, power panels, electrical distribution
              systems, lighting fixtures, space heaters, air conditioning,
              plumbing, and fencing.  Lessor may require that Lessee remove any
              or all of said alterations, improvements, additions or Utility
              Installations at the expiration of the term, and restore the
              Premises and the Industrial Center to their prior condition.
              Lessor may require Lessee to provide Lessor, at Lessee's sole cost
              and expense, a lien and completion bond in an amount equal to one
              and one-half times the estimated cost of such improvements, to
              inure Lessor against any liability for mechanic's and
              materialmen's liens and to insure completion of the work.  Should
              Lessee make any alterations, improvements, additions or Utility
              Installations without the prior approval of Lessor, Lessor may, at
              any time during the term of this Lease, require that Lessee remove
              any or all of the same.

       (b)    Any alterations, improvement, additions or Utility Installations
              in or about the Premises or the Industrial Center that Lessee
              shall desire to make and which requires the consent of the Lessor
              shall be presented to Lessor in written form, with proposed
              detailed plans.  If Lessor shall give its consent, the consent
              shall be deemed conditioned upon Lessee acquiring a permit to do
              so from appropriate governmental agencies, the furnishing of a
              copy thereof to Lessor prior to the commencement of the work and
              the compliance by Lessee of all conditions of said permit in a
              prompt and expeditious manner.

       (c)    Lessee shall pay, when due, all claims for labor or materials
              furnished or alleged to have been furnished to or for Lessee at or
              for use in the Premises, which claims are or may be secured by any
              mechanic's or materialmen's lien against the Premises, or the
              Industrial Center, or any interest therein.  Lessee shall give
              Lessor not less than ten (10) days' notice prior to the
              commencement of any work in the Premises, and Lessor shall have
              the right to post notices of non-responsibility in or on the
              Premises or the Building as provided by law.  If Lessee shall, in
              good faith contest the validity of any such lien, claim or demand,
              then Lessee shall, at its sole expense defend itself and Lessor
              against the same and shall pay and satisfy any such adverse
              judgement that may be rendered thereon before the enforcement
              thereof against the Lessor or the Premises or the Industrial

<PAGE>

              Center, upon the condition that if Lessor shall require, Lessee
              shall furnish to Lessor a surety bond satisfactory to Lessor in an
              amount equal to such contested lien claim or demand indemnifying
              Lessor against liability for the same and holding the Premises and
              the Industrial Center free from the effect of such lien or claim.
              In addition, Lessor may require Lessee to pay Lessor's attorneys
              fees and costs in participating in such action if Lessor shall
              decide it is to Lessor's best interest to do so.

       (d)    All alterations, improvements, additions and Utility Installations
              (whether or not such Utility Installations constitute trade
              fixtures of Lessee), which may be made on the Premises, shall be
              the property of Lessor and shall remain upon and be surrendered
              with the Premises at the expiration of the Lease term, unless
              Lessor requires their removal pursuant to paragraph 7.3(a).
              Notwithstanding the provisions of this paragraph 7.3(d).  Lessee's
              machinery and equipment, other than that which is affixed to the
              Premises so that it cannot be removed without material damaged to
              the Premises, and other than Utility Installations, shall remain
              the property of Lessee and may be removed by Lessee subject to the
              provision of paragraph 7.2.

7.4    UTILITY ADDITIONS.  Lessor reserves the right to install new or
       additional utility facilities throughout the Building and the Common
       Areas for the benefit of Lessor or Lessee, or any other lessee of the
       Industrial Center, including, but not by way of limitation, such
       utilities as plumbing, electrical systems, security systems,
       communication system, and fire protection and detection systems, so long
       as such installations do not unreasonably interfere with Lessee's use of
       the Premises.

8.     INSURANCE; INDEMNITY.

8.1    LIABILITY INSURANCE - LESSEE.
                                   See page 8 after article number 49

8.2    LIABILITY INSURANCE - LESSOR.  Lessor shall obtain and keep in force
       during the term of this Lease a policy of Combined Single Limit Bodily
       Injury and Property Damage Insurance, inuring Lessor, but not Lessee,
       against any liability arising out of the ownership, use occupancy or
       maintenance of the Industrial Center in an amount not less than
       $1,000,000 per occurrence.

8.3    PROPERTY INSURANCE.  Lessor shall obtain and keep in force during the
       term of this Lease a policy or policies of insurance coving loss or
       damage to the industrial Center improvements, but not Lessee's personal
       property, fixtures, equipment or tenant improvement, in an amount not to
       exceed the full replacement value thereof, as the same may exist from
       time to time, providing protection against all perils including within
       the classification of fire, extended coverage, vandalism, malicious
       mischief, flood (in the event same is required by a lender having a lien
       on the Premises) special extended perils ("all risk", as such term is
       used in the insurance industry), plate glass insurance and such other
       insurance as Lessor deems advisable.  In addition, Lessor shall obtain
       and keep in force, during the term of this Lease, a policy of rental
       value insurance covering a period of one year, with loss payable to
       Lessor, which insurance shall also cover all Operating expenses for said
       period.  In the event that the Premises shall suffer an insured loss as
       defined in paragraph 9.1(g) hereof, the deductible amounts under the
       casualty insurance policies relating to the Premises shall be paid by
       Lessee.

8.4    PAYMENT OF PREMIUM INCREASE.

       (a)    After the term of this Lease has commenced, Lessee shall not be
              responsible for paying Lessee's Share of any increase in the
              property insurance premium for the Industrial Center specified by
              Lessor's Insurance carrier as being caused by the use, acts or
              omissions of any other lessee of the Industrial Center, or by the
              nature of such other lessee's occupancy which create an
              extraordinary or unusual risk.

<PAGE>

       (b)    Lessee, however, shall pay the entirety of any increase in the
              property insurance premium for the Industrial Center over what is
              was immediately prior to the commencement of the term of this
              Lease if the increase is specified by Lessor's insurance carrier
              as being caused by the nature of Lessee's occupancy or any act of
              omission of Lessee.

8.5    INSURANCE POLICIES.  Insurance required hereunder shall be in companies
       holding a "General Policyholders Rating" of at least B plus, or such
       other rating as may be required by a lender having a lien on the
       Premises, as set forth in the most current issue of "Best's Insurance
       Guide."  Lessee shall not do or permit to be done anything which shall
       invalidate the insurance policies carried by Lessor.  Lessee shall
       deliver to Lessor copies of liability insurance policies required under
       paragraph 8.1 or certificates evidencing the existence and amounts of
       such insurance within seven (7) days after the commencement date of this
       Lease.  No such policy shall be cancellable or subject to reduction of
       coverage or other modification except after thirty (30) days prior
       written notice to Lessor.  Lessee shall, at least thirty (30) days prior
       to the expiration of such policies, furnish Lessor with renewals or
       "binders" thereof.

8.6    WAIVER OF SUBROGATION.  Lessee and Lessor each hereby release and relieve
       the other, and waive their entire right of recovery against the other for
       loss or damage arising out of or incident to the perils insured against
       which perils occur in, on or about the Premises, whether due to the
       negligence of Lessor or Lessee or their agents, employees, contractors
       and/or invitees.  Lessee and Lessor shall, upon obtaining the policies of
       insurance required give notice to the insurance carrier or carriers that
       the foregoing mutual waiver of subrogation is contained in this Lease.

8.7    INDEMNITY.  Lessee shall indemnify and hold harmless Lessor from and
       against any and all claims arising from Lessee's use of the Industrial
       Center, or from the conduct of Lessee's business or from any activity,
       work or things done, permitted or suffered by Lessee in or about the
       Premises or elsewhere and shall further indemnify and hold harmless
       Lessor from and against any and all claims arising from any breach or
       default in the performance of any obligation on Lessee's part to be
       performed under the terms of this Lease, or arising from any act or
       omission of Lessee, or  any of Lessee's agents, contractors, or
       employees, and from and against all costs, attorney's fee, expenses and
       liabilities incurred in the defense of any such claim or any action or
       proceeding brought thereon and in case any action or proceeding be
       brought against Lessor by reason of any such claim.  Lessee upon notice
       from Lessor shall defend the same at Lessee's expense by counsel
       reasonably satisfactory to Lessor and Lessor shall cooperate with Lessee
       in such defense.  Lessee, as a material part of the consideration to
       Lessor, hereby assumes all risk of damage to property of Lessee or injury
       to persons, in upon or about the Industrial Center arising from any cause
       and Lessee hereby waives all claims in respect thereof against Lessor.
       See Addendum.

8.8    EXEMPTION OF LESSOR FROM LIABILITY.  Lessee hereby agrees that Lessor
       shall not be liable for injury to Lessee's business or any loss of
       income therefrom or for damage to the goods, wares, merchandise or other
       property of Lessee, Lessee's employees, invitees, customers, or nay other
       person in or about the Premises or the Industrial Center, nor shall
       Lessor be liable for injury to the person of Lessee, Lessee's employees,
       agents or contractors, whether such damage or injury is caused by or
       results from fire, steam, electricity, gas water or rain, or from the
       breakage, leakage, obstruction or other defects of pipes, sprinklers,
       wires, appliances, plumbing, air conditioning or lighting fixtures, or
       from any other cause, whether said damage or injury results from
       conditions arising upon the Premises or upon other portions of the
       Industrial Center, or from other sources or places and regardless of
       whether the cause of such damage or injury or the means of repairing the
       same is inaccessible to Lessee.  Lessor shall not be liable for any
       damages arising from any act or neglect of any other lessee, occupant or
       user of the Industrial Center, nor from the failure of Lessor to enforce
       the provisions of any other lease of the Industrial Center.

              Lessor's election to do so within 30 days after the date of

       (b)    Notwithstanding paragraph 9.4 (a), in the event that Lessee has an
              option to extend or renew this Lease, and the time within which
              said option may be exercised has not yet expired, Lessee shall
              exercise such option, if it is to be exercised at all, no later
              than twenty (20) days after the occurrence of an Insured Loss
              falling within the classification of Premises Partial Damage
              during the last six months of the term of this Lease.  If

              continues shall be abated in proportion to the degree to which

              rent, if any, Lessee shall have no claim against Lessor for any
              damage suffered by reason of any such damage, destruction, repair
              or restoration.
       (b)    If Lessor shall be obligated to repair or restore the Premises
              under the provisions of this paragraph 9 and shall not commence
              such repair or restoration within ninety (90) days after such
              obligation shall accrue, Lessee may at Lessee's option cancel and
              terminate this Lease by giving Lessor written notice of Lessee's
              election to do so at any time prior to the commencement of such

       to this paragraph 9, an equitable adjustment shall be made concerning
       advance rent and any advance payment made by Lessee to Lessor.  Lessor
       shall, in addition, return to Lessee so much of Lessee's security deposit
       as has not theretofore been applied by Lessor.

9.7    WAIVER.  Lessor and Lessee waive the provisions of any statute which
       relate to termination of leases when leased property is destroyed and
       agree that such event shall be governed by the terms of this Lease.

10.    REAL PROPERTY TAXES.


<PAGE>

10.1   PAYMENT OF TAXES.  Lessor shall pay the real property tax, as defined in
       paragraph 10.3, applicable to the Industrial Center subject to
       reimbursement by Lessee of Lessee's Share of such taxes in accordance
       with the provisions of paragraph 4.2, except as other wise provide in
       paragraph 10.2.

10.2   ADDITIONAL IMPROVEMENTS.  Lessee shall not be responsible for paying
       Lessee's Share of any increase in real property tax specified in the tax
       assessor's records and work sheets as being caused by additional
       improvements placed upon the Industrial Center by other Lessees or by
       Lessor for the exclusive enjoyment of such other lessees.  Lessee shall,
       however, pay to Lessor at the time that Operating Expenses are payable
       under paragraph 4.2 (c) the entirety of any increase in real property tax
       if assessed solely by reason of additional improvements placed upon the
       Premises by Lessee or at Lessee's request.

10.3   DEFINITION OF "REAL PROPERTY TAX."  As used herein, the term "real
       property tax" shall include any form of real estate tax or assessment,
       general, special, ordinary or extraordinary, and any license fee,
       commercial rental tax, improvement bond or bonds, levy or tax (other than
       inheritance, personal income or estate taxes) imposed on the Industrial
       Center or any portion thereof by any authority having the direct or
       indirect power to tax, including any city, county, state or federal
       government, or any school, agricultural, sanitary, fire, street, drainage
       or other improvement district thereof, as against any legal or equitable
       interest of Lessor in the Industrial Center or in any portion thereof, as
       against Lessor's right to rent or other income therefrom, and as against
       Lessor's business of leasing the Industrial Center.  The term "real
       property tax" shall also include any tax, fee, levy, assessment or charge
       (i) in substitution of, partially or totally, any tax, fee levy,
       assessment or charge hereinabove included within the definition of "real
       property tax," or (ii) the nature of which was hereinbefore included
       within the definition of "real property tax," or (iii) which is imposed
       for a service or right not charge prior to June 1, 1978, or, if
       previously charged, has been increased since June 1, 1078, or (iv) which
       is imposed as a result of a transfer, either partial or total, of
       Lessor's interest in the Industrial Center or which is added to a tax or
       charge hereinbefore included within the definition of real property tax

       hereof.

       Lessee's Share of the real property tax liability shall be an equitable
       proportion of the real property taxes for all of the land and
       improvements included within the tax parcel assessed, such proportion to
       be determined by Lessor from the respective valuations assigned in the
       assessor's work sheets or such other information as may be reasonably
       available.  Lessor's reasonable determination thereof, in good faith,
       shall be conclusive.

10.5   PERSONAL PROPERTY TAXES.

       (a)    Lessee shall pay prior to delinquency all taxes assessed against
              and levied upon trade fixtures, furnishings, equipment and all
              other personal property of Lessee contained in the premises or
              else where.  When possible, Lessee shall cause said trade
              fixtures, furnishings, equipment and all other personal property
              to be assessed and billed separately from the real property of
              Lessor.

       (b)    If any of Lessee's said personal property shall be assessed with
              Lessor's real property, Lessee shall pay to Lessor the taxes
              attributable to Lessee within ten (10) days after receipt of a
              written statement setting forth the taxes applicable to Lessee's
              property.

11.    UTILITIES.  Lessee shall pay for all water, gas, heat, light, power,
       telephone and other utilities and services supplied to the Premises,
       together with any taxes thereon.  If any such services are not separately
       metered to the Premises, lessee shall pay at Lessor's option, either
       Lessee's Share or a reasonable proportion to be determined by Lessor of
       all charges jointly metered with other premises in the Building.


<PAGE>

12.    ASSIGNMENT AND SUBLETTING.

12.1   LESSOR'S CONSENT REQUIRED.  Lessee shall not voluntarily or by operation
       of law assign, transfer, mortgage, sublet, or otherwise transfer or
       encumber all or any part of Lessee's interest in the Lease or in the
       Premises, without Lessor's prior written consent, which Lessor shall not
       unreasonably withhold.  Lessor shall respond to Lessee's request for
       consent hereunder in a timely manner and any attempted assignment,
       transfer mortgage, encumbrance or subletting without such consent shall
       be void, and shall constitute a breach of this Lease without the need for
       notice to Lessee under paragraph 13.1.  See Addendum for additional
       terms.


12.3   TERMS AND CONDITIONS OF ASSIGNMENT. Regardless of Lessor's consent, no
       assignment shall release Lessee of Lessee's obligations hereunder or
       alter the primary liability of Lessee to pay the Base Rent and Lessee's
       Share of Operating Expenses, and to perform all other obligations to be
       performed by Lessee hereunder. Lessor may accept rent from any person
       other than the Lessee pending approval or disapproval of such assignment.
       Neither a delay in the approval or disapproval of such assignment nor the
       acceptance of rent shall constitute a waiver or estoppel of Lessor's
       right to exercise its remedies for the breach of any of the terms or
       conditions of this paragraph 12 or this Lease. Consent to one assignment
       shall not be deemed consent to any subsequent assignment. In the event of
       default by any assignee of Lessee or any successor of Lessee, in the
       performance of any of the terms hereof, Lessor may proceed directly
       against Lessee without the necessity of exhausting remedies against said
       assignee. Lessor may consent to subsequent assignments of this Lease or
       amendments or modifications to this Lease with assignees of Lessee,
       without notifying Lessee, or any successor of Lessee, and without
       obtaining its or their consent thereto and such action shall not relieve
       Lessee of liability under this Lease.

12.4   TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. Regardless of Lessor's
       consent, the following terms and conditions shall apply to any subletting
       by Lessee of all or part of the premises and shall be included in the
       subleases:

       (a)    Lessee hereby assigns and transfers to Lessor all of Lessee's
              interests in all rentals and income arising from any sublease
              heretofore or hereafter made by Lessee, and Lessor may collect
              such rent and income and apply same toward Lessee's obligations
              under this Lease; provided, however, that until a default shall
              occur in the performance of Lessee's obligations under this Lease,
              Lessee may receive, collect and enjoy the rents accruing under
              such a sublease. Lessor shall not, by reason of this or any other
              assignment of such sublease to Lessor nor by reason of the
              collection of the rents from a sublessee, be deemed liable to the
              sublessee for any failure of Lessee to perform and comply with any
              of Lessee's obligations to such sublessee under such sublease.
              Lessee hereby irrevocably authorizes and directs any such
              sublease, upon a written notice from Lessor stating that a default
              exists in the performance of Lessee's obligations under this
              Lease, to pay Lessor the rents due and to become due under the
              sublease. Lessee agrees that such sublessee shall have the right
              to rely upon any such statement and request from Lessor, and that
              such sublessee shall pay such rents to Lessor without any
              obligation or right to inquire as to whether such default exists
              and notwithstanding any notice from or claim from Lessee to the
              contrary. Lessee shall have no right or claim against such
              sublessee or Lessor for any such rents so paid by said sublessee
              to Lessor.

       (b)    No sublease entered into by Lessee shall be effective unless and
              until it has been approved in writing by Lessor. In entering into
              any sublease, Lessee shall use only such form of sublease as is
              satisfactory to Lessor, and once approved by Lessor, such sublease
              shall not be changed or modified without Lessor's prior written
              consent. Any sublease shall, by reason of entering into a sublease
              under this Lease, be deemed, for the benefit of the Lessor, to
              have assumed and agreed to conform and comply with each and every
              obligation herein to be performed by Lessee other than such
              obligations as are contrary to or inconsistent with provisions
              contained in a sublease to which Lessor has expressly consented in
              writing.


<PAGE>

       (c)    If Lessee's obligations under this Lease have been guaranteed by
              third parties, then a sublease, and Lessor's consent thereto,
              shall not be effective unless said guarantors give their written
              consent to such sublease and the terms thereof.

       (d)    The consent by Lessor to any subletting shall not release Lessee
              from its obligations or alter the primary liability of Lessee to
              pay the rent and perform and comply with all of the obligations of
              Lessee to be performed under this Lease.

       (e)    The consent by Lessor to any subletting by Lessee or to any
              assignment or subletting by the sublessee. However, Lessor may
              consent to subsequent sublettings and assignments of the sublease
              or any amendments or modifications thereto without notifying
              Lessee or anyone else liable on the Lease or sublease and without
              obtaining their consent and such action shall not relieve such
              persons from liability.

       (f)    In the event of any default under this Lease, Lessor may proceed
              directly against Lessee, any guarantors or any one else
              responsible for the performance of this Lease, including the
              sublessee, without first exhausting Lessor's remedies against any
              other person or entity responsible therefore to Lessor, or any
              security held by Lessor or Lessee.

       (g)    In the event Lessee shall default in the performance of its
              obligations under this Lease, Lessor, at its option and without
              any obligation to do so, may require any sublessee to attorn to
              Lessor, in which event Lessor shall undertake the obligations of
              Lessee under such sublease from the time of the exercisr of said
              option to the termination of such sublease; provided, however,
              Lessor shall not be liable for any prepaid rents or security
              deposit paid by such sublessee to Lessee or for any other prior
              defaults of Lessee under such sublease.

       (h)    Each and every consent required of Lessee under a sublease shall
              also require the consent of Lessor.

       (i)    No sublessee shall further assign or sublet all or any part of the
              Premises without Lessor's prior written consent.

       (j)    Lessor's written consent to any subletting of the Premises by
              Lessee shall not constitute an acknowledgement that no default
              then exists under this Lease of the obligations to be performed by
              Lessee nor shall such consent be deemed a waiver of any then
              existing default, except as may be otherwise stated by Lessor at
              the time.

       (k)    With respect to any subletting to which Lessor has consented,
              Lessor agrees to deliver a copy of any notice of default by Lessee
              to the sublessee. Such sublessee shall have the right to cure a
              default of Lessee within ten (10) days after service of said
              notice of default upon such sublessee, and the sublessee shall
              have a right of reimbursement and offset from and against Lessee
              for any such defaults cured by the sublessee.

12.5   ATTORNEY'S FEES. In the event Lessee shall assign or sublet the Premises
       or request the consent of Lessor to any assignment or subletting or if
       Lessee shall request the consent of Lessor for any act Lessee proposes
       to do then Lessee shall pay Lessor's reasonable attorneys fees incurred
       in connection therewith, such attorneys fees not to exceed $350.00 for
       each subsequent request.

13.    DEFAULT; REMEDIES.

       13.1    DEFAULT. The occurrence of any one or more of the following
       events shall constitute a material default of this Lease by Lessee:

              (a)    The vacating or abandonment of the Premises by Lessee.


<PAGE>

              (b)    The failure by Lessee to make any payment of rent or any
                     other payment required to be made by Lessee hereunder, as
                     and when due, where such failure shall continue for a
                     period of three (3) days after written notice thereof from
                     Lessor to Lessee. In the even that Lessor serves Lessee
                     with a Notice to Pay Rent or Quite pursuant to applicable
                     Unlawful Detainer statutes such Notice to Pay Rent or Quit
                     shall also constitute the notice required by this
                     subparagraph.
              (c)    Except as otherwise provided in this Lease, the failure by
                     Lessee to observe or perform any of the covenants,
                     conditions or provisions of this Lease to be observed or
                     performed by Lessee, other than described in paragraph (b)
                     above, where such failure shall continue for a period of
                     thirty (30) days after written notice thereof from Lessor
                     to Lessee; provided, however that if the nature of Lessee's
                     noncompliance is such that more than thirty (30) days are
                     reasonably required for its cure, then Lessee shall not be
                     deemed to be in default if Lessee commenced such cure
                     within said thirty (30) day period and thereafter
                     diligently prosecutes such cure to completion. To the
                     extent permitted by law, such thirty (30) day notice shall
                     constitute the sole and exclusive notice required to be
                     given to Lessee under applicable Unlawful Detainer
                     statutes.
              (d)    (i) The making by Lessee of any general arrangement or
                     general assignment for the benefit of creditors; (ii)
                     Lessee becomes a "debtor" as defined in 11 U.S.C. Section
                     101 or any successor statute thereto (unless, in the case
                     of a petition filed against Lessee, the same is dismissed
                     within sixty (60) days) (iii) the appointment of a trustee
                     or receiver to take possession of substantially all of
                     Lessee's assets located at the Premises or of Lessee's
                     interest in this Lease, where possession is not restored to
                     Lessee within thirty (30) days; or (iv) the attachment,
                     execution or other judicial seizure of substantially all of
                     Lessee's assets located at the Premises or of Lessee's
                     interest in this Lease, where such seizure is not
                     discharged within thirty (30) days. In the event that any
                     provision of this paragraph 13.1 (d) is contrary to any
                     applicable law, such provision shall be of no force or
                     effect.
              (e)    The discovery by Lessor that any financial statement given
                     to Lessor by Lessee, any assignee of Lessee, any subtenant
                     of Lessee, any successor in interest of Lessee or any
                     guarantor of Lessee's obligation hereunder, was materially
                     false. See addendum.

13.2   REMEDIES. In the event of any such material default by Lessee, Lessor
       may at any time thereafter, with or without notice or demand and without
       limiting Lessor in the exercise of any right or remedy which Lessor may
       have by reason of such default:

              (a)    Terminate Lessee's right to possession of the Premises by
                     any lawful means, in which case this Lease and the term
                     hereof shall terminate and Lessee shall immediately
                     surrender possession of the Premises to Lessor. In such
                     event Lessor shall be entitled to recover from Lessee all
                     damages incurred by Lessor by reason of Lessee's default
                     including, but not limited to, the cost of recovering the
                     Premises; expenses of reletting, including necessary
                     renovation and alteration of the Premises, reasonable
                     attorney's fees, and any real estate commission actually
                     paid; the worth at the time of award by the court having
                     jurisdiction thereof of the amount by which the unpaid rent
                     for the balance of the term after the time of such award
                     exceeds the amount of such rental loss for the same period
                     that Lessee proves could be reasonably avoided; that
                     portion of the leasing commission paid by Lessor pursuant
                     to paragraph 15 applicable to the unexpired terms of this
                     Lease.
              (b)    Maintain Lessee's right to possession in which case this
                     Lease shall continue in effect whether or not Lessee shall
                     have vacated or abandoned the Premises. In such event
                     Lessor shall be entitled to enforce all of Lessor's rights
                     and remedies under this lease, including the right to
                     recover rent as it becomes due hereunder.


<PAGE>

              (c)    Persue any other remedy now or hereafter available to
                     Lessor under the laws or judicial decisions of the state
                     wherein the Premises are located. Unpaid installments of
                     rent and other unpaid monetary obligations of Lessee under
                     the terms of this Lease shall bear interest from the date
                     due at the maximum rate then allowable by
                     law. Lessor's remedies shall include the relief set forth
                     in Section 1951.2 of the California Civil Code.


13.3   DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor fails to
       perform obligations required of Lessor within a reasonable time, but in
       no event later than thirty (30) days after written notice by Lessee to
       Lessor and to the holder of any first mortgage or deed of trust covering
       the Premises whose name and address shall have theretofore been furnished
       to Lessee in writing, specifying wherein Lessor has failed to perform
       such obligation; provided, however, that if the nature of Lessor's
       obligation is such that more than thirty (30) days are required for
       performance then Lessor shall not be in default if Lessor commences
       performance within such thirty (30) day period and thereafter diligently
       prosecutes the same to completion.

13.4   LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee to
       Lessor of Base Rent, Lessee's Share of Operating Expenses or other sums
       due hereunder will cause Lessor to incur costs not contemplated by this
       lease, the exact amount of which will be extremely difficult to
       ascertain. Such costs include, but are not limited to, processing and
       accounting charges, and late charges which may be imposed on Lessor by
       the terms of any mortgage or trust deed covering the Property.
       Accordingly, if any installment of Base Rent, Operating Expenses, or any
       other sum due from Lessee shall not be received by Lessor or Lessor's
       designee within ten (10) days after such amount shall be due, then
       without any requirement for notice to Lesee, Lessee shall pay to Lessor a
       late charge equal to 6% of such overdue amount. The parties hereby agree
       that such late charge represents a fair and reasonable estimate of the
       costs Lessor will incur by reason of late payment by Lessee. Acceptance
       of such late charge by Lessor shall in no eventconstitute a waiver of
       Lessee's default with respect to such overdue amount, nor prevent Lessor
       from exercising any of the other rights and remedies granted hereunder.
       In the event that a late charge is payable hereunder, whether or not
       collected, for three (3) consecutive installments of any of the aforesaid
       monetary obligations of Lessee, then Base Rent shall automatically become
       due and payable quarterly in advance, rather than monthly,
       notwithstanding paragraph 4.1 or any other provision of this Lease to the
       contrary.

14.    CONDEMNATION. If the Premises or any portion thereof or the Industrial
       Center are taken under the power of eminent domain, or sold under the
       threat of the exercise of said power (all of which are herein called
       "condemnation"), this Lease shall terminate as to the part so taken as of
       the date the condemning authority takes title or possession, whichever
       first occurs. If more than ten percent of the floor area of the
       Premises, or more than twenty-five percent of that portion of the
       Common Areas designated as parking for the Industrial Center is taken by
       condemnation, Lessee may, at Lessee's option, to be exercised in writing
       only within ten (10) days after Lessor shall be given Lessee written
       notice of such taking (or in the absence of such notice, within ten
       days after the condemning authority shall have taken possession)
       terminate this Lease as of the date the condemning authority takes such
       possession. If Lessee does not terminate this Lease in accordance with
       the foregoing, this Lease shall remain in full force and effect as to the
       portion of the premises remaining, except that the rent shall be reduced
       in the proportion that the floor area of the Premises taken bears to the
       total floor area of the Premises. No reduction of rent shall occur if the
       only area taken is that which does not have the Premises located thereon.
       Any award for the taking of all or any part of the Premises under the
       power of eminent domain or any payment made under threat of the exercise
       of such power shall be the property of Lessor, whether such award shall
       be made as compensation for diminution in value of the leasehold or for
       the taking of the fee, or as severance damages; provided, however, that
       Lessee shall be entitled to any award for loss of or damage to Lessee's
       trade fixtures and removable personal property. In the event that this
       lease is not terminated by reason of such condemnation, Lessor shall to
       the extent of severance damages received by Lessor in connection with
       such condemnation, repair any damage to the Premises caused by such
       condemnation except to the extent that Lessee has been reimbursed
       therefore by the condemning authority. Lessee shall pay any amount in
       excess of such severance damages required to complete such repair.


<PAGE>

15.    BROKER'S FEE.

(a)    Upon execution of this Lease by both parties, Lessor shall pay to
       Pacifica Commercial Realty Licensed real estate broker(s), a fee as set
       forth in a separate agreement between Lessor and said broker(s), the sum
       of $3,832.40, for brokerage services rendered by said broker(s) to Lessor
       in this transaction.
(b)    Lessor agrees to pay said fee not only on behalf of Lessor but also on
       behalf of any person, corporation, association, or other entity having an
       ownership interest in said real property or any part thereof, when such
       fee is due hereunder. Any transferee of Lessor's interests in this Lease,
       whether such transfer is by agreement or by operation of law, shall be
       deemed to have assumed Lessor's obligation under this paragraph 15. Said
       broker shall be a third party beneficiary of the provisions of this
       paragraph 15.

16.    ESTOPPEL CERTIFICATE.

(a) Each party (as "responding party") shall at any time upon not less than
    ten (10) days' prior written notice from the other party ("requesting
    party") execute, acknowledge and deliver to the requesting party a
    statement in writing (i) certifying that this Lease is unmodified and in
    full force and effect (or, if modified, stating the nature of such
    modification and certifying that this Lease, as so modified, is in full
    force and effect) and the date to which the rent and other charges are
    paid in advance, if any, and (ii) acknowledging that there are not, to
    the responding party's knowledge, any uncured defaults on the part of the
    requesting party, or specifying such defaults if they are claimed. Any
    such statement may be conclusively relied upon by any prospective
    purchaser or encumbrancer of the Premises or of the business of the
    requesting party.

(b) At the requesting party's option, the failure to deliver such statement
    within such time shall be a material default of this Lease by the party
    who is to respond, without any further notice to such party, or it shall
    be conclusive upon such party that (i) this lease is in full force and
    effect, without modification except as may be represented by the
    requesting party, (ii) there are no uncured defaults in the requesting
    party's performance, and (iii) if Lessor is the requesting party, not
    more than one month's rent has been paid in advance.

(c) If Lessor desires to finance, refinance, or sell the Property, or any
    part thereof, Lessee hereby agrees to deliver to any lender or purchaser
    designated by Lessor such financial statementsof Lessee as may be
    reasonably required by such lender or purchaser. Such statements shall
    include the past three (3) years' financial statements of Lessee. All
    such financial statements shall be received by Lessor and such lender or
    purchaser in confidence and shall be used only for the purposes herein
    set forth.

17.    LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the
       owner or owners, at the time in question, of the fee title or a lessee's
       interest in a ground lease of the Industrial Center, and except as
       expressly provided in paragraph 15, in the event if any transfer of such
       title or interest, Lessor herein named (and in case of any subsequent
       transfers then the grantor) shall be relieved from and after the date of
       such transfer of all liability as respects Lessor's obligations
       thereafter to be performed, provided that any fundsin the hands of the
       Lessor or the then grantor at the time of such transfer, in which Lessee
       has an interest, shall be delivered to the grantee. The obligations
       contained in this Lease to be performed by Lessor shall, subject as
       aforesaid, be binding on Lessor's successors and assigns, only during
       their respective periods of ownership.

18.    SEVERABILITY. The invalidity of any provision of this Lease as determined
       by a court of competent jurisdiction, shall in no way affect the validity
       of any other provision hereof.

19.    INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided,
       any amount due to Lessor not paid when due shall bear interest at the
       maximum rate then allowable by law from the date due. Payment of such
       interest shall nor excuse or cure any default by Lessee under this Lease;
       provided, however, that interest shall not be payable on late charges
       incurred by Lessee nor on any amounts upon which late charges are paid by
       Lessee.


<PAGE>

20.    TIME OF ESSENCE. Time is of the essence with respect to the obligations
       to be performed under this Lease.

21.    ADDITIONAL RENT. All monetary obligations of Lessee to Lessor under the
       terms of this Lease, included but not limited to Lessee's Share of
       Operating Expenses and insurance and tax expenses payable shall be deemed
       to be rent.

22.    INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS. This Lease contains all
       agreements of the parties with respect to any matter mentioned herein. No
       prior or contemporaneous agreement or understanding pertaining to any
       such matter shall be effective. This lease may be modified in writing
       only, signed by the parties in interest at the time of the modification.
       Except as otherwise stated in this Lease, Lessee hereby acknowledges that
       neither the real estate broker listed in paragraph 15 hereof nor any
       cooperating broker on this transaction nor the Lessor or any employee or
       agents of any said persons has made any oral or written warranties or
       representations to Lessee relative to the condition or use by Lessee of
       the Premises or the Property and Lessee acknowledges that Lessee assumes
       all responsibility regarding the Occupational Safety Health Act, the
       legal use and adaptability of the Premises and the compliance thereof
       with all applicable laws and regulations in effect during the term of
       this Lease except as otherwise specifically stated in this Lease.

23.    NOTICES. Any notice required or permitted to be given hereunder shall be
       in writing and may be given by personal delivery or by certified mail,
       and if given personally or by mail, shall be deemed sufficiently given if
       addressed to Lessee or to Lessor at the address noted below the signature
       of the respective parties, as the case may be. Either party may by notice
       to the other specify a different address for notice purposes. A copy of
       all notices required or permitted to be given to Lessor hereunder shall
       be concurrently transmitted to such party or parties at such addresses as
       Lessor may from time to time hereafter designate by notice to Lessee.

24.    WAIVERS. No waiver by Lessor or any provision hereof shall be deemed a
       waiver of any other provision. Lessor's consent to, or approval of, any
       act shall not be deemed to render unnecessary the obtaining of Lessor's
       consent to or approval of any subsequent act by Lessee. The acceptance of
       rent hereunder by Lessor shall not be a waiver of any preceding breach by
       Lessee of any provision hereof, other than the failure of Lessee to pay
       the particular rent so accepted, regardless of Lessor's knowledge of such
       preceding breach at the time of acceptance of such rent.

25.    RECORDING. Either Lessor or Lessee shall, upon request of the other,
       execute, acknowledge and deliver to the other a "short form" memorandum
       of this lease for recording purposes.

26.    HOLDING OVER. If Lessee, with Lessor's consent, remains in possession of
       the Premises or any part thereof after the expiration of the term hereof,
       such occupancy shall be a tenancy from month to month upon all the
       provisions of this Lease pertaining to the obligations of Lessee, but all
       Options, if any, granted under the terms of this Lease shall be deemed
       terminated and be of no further effect during said month to month
       tenancy.


27.    CUMULATIVE REMEDIES.  No remedy or election hereunder shall be deemed
       exclusive but shall, wherever possible, be cumulative with all other
       remedies at law or in equity.

28.    COVENANTS AND CONDITIONS.  Each provision of this Lease performable by
       Lessee shall be deemed both a covenant and a condition.

29.    BINDING EFFECT; CHOICE OF LAW. Subject to any provisions hereof
       restricting assignment or subletting by Lessee and subject to the
       provisions of paragraph 17, this Lease shall bind the parties, their
       personal representatives, successors and assign.  This Lease shall be
       governed by the laws of the State where the Industrial Center is located
       and any litigation concerning this Lease


<PAGE>

       between the parties hereto shall be initiated in the country in which
       the Industrial Center is located.

30.    SUBORDINATION.

       (a)    This Lease, and any Option granted hereby, at Lessor's option,
              shall be subordinate to any ground lease, mortgage, deed or trust,
              or any other hypothecation or security now or hereafter placed
              upon the Industrial Center and to any and all advances made on the
              security thereof and to all renewals, modifications,
              consolidations, replacements and extensions thereof.
              Notwithstanding such subordination. Lessee's right to quiet
              possession of the Premises shall not be disturbed if Lessee is not
              in default and so long as Lessee shall pay the rent and observe
              and perform all of the provisions of this Lease, unless this Lease
              is otherwise terminated pursuant to its terms.  If any mortgagee,
              trustee or ground lessor shall elect to have this Lease and any
              Options granted hereby prior to the lien of its mortgage, deed of
              trust or ground lease, and shall give written notice thereof to
              Lessee, this Lease and such Options shall be deemed prior to such
              mortgage, deed of trust or ground lease, whether this lease or
              such Options are dated prior or subsequent to the date of said
              mortgage, deed of trust or ground lease or the date of recording
              thereof.

       (b)    Lessee agrees to execute any documents required to effectuate an
              attornment, a subordination or to make this Lease or any Option
              granted herein prior to the lien of any mortgage, deed of trust or
              ground lease, as the case may be.  Lessee's failure to execute
              such documents within ten (10) days after written demand shall
              constitute a material default by Lessee hereunder without further
              notice to Lessee or, at Lessor's option.  Lessor shall execute
              such documents on behalf of Lessee, as Lessee's attorney-in-fact.
              Lessee does hereby make, constitute and irrevocably appoint Lessor
              as Lessee's attorney-in-fact and in Lessee's name, place and
              stead, to execute such documents in accordance with this paragraph
              30(b).

31.    ATTORNEY'S FEES.  If either party or the broker(s) named herein bring an
       action to enforce the terms hereof or declare rights hereunder, the
       prevailing party in any such action, on trial or appeal, shall be
       entitled to his reasonable attorney's fees to be paid by the losing party
       as fixed by the court.  The provisions of this paragraph shall inure to
       the benefit of the broker named herein who seeks to enforce a right
       hereunder.

32.    LESSOR'S ACCESS.  Lessor and Lessor's agents shall have the right to
       enter the Premises at reasonable times for the purpose of inspecting the
       same, showing the same to prospective purchasers, lenders, or lessees,
       and making such alternations, repairs, improvements or additional to the
       Premises or to the building of which they are part of Lessor may deem
       necessary or desirable.  Lessor may at any time place on or about the
       Premises or the Building any ordinary "For Sale" signs and Lessor may at
       any time during the last 120 days of the term hereof place on or about
       the Premises any ordinary "For lease" signs.  All activities of Lessor
       pursuant to this paragraph shall be without abatement of rent, nor shall
       Lessor have any liability to Lessee for the same.

33.    AUCTIONS.  Lessee shall not conduct, nor permit to be conducted, either
       voluntarily or involuntarily or involuntarily, any auction upon the
       Premises or the Common Areas without first having obtained Lessor's prior
       written consent.  Notwithstanding anything to the contrary in this Lease,
       Lessor shall not be obligated to exercise any standard of reasonableness
       in determining whether to grant such consent.

34.    SIGNS.  Lessee shall not place any sign upon the Premises or the
       Industrial Center without Lessor's prior written consent.  Under no
       circumstances shall Lessee place a sign on any roof of the Industrial
       Center.


<PAGE>

35.    MERGER.  The voluntary or other surrender of this Lease by Lessee, or a
       mutual cancellation thereof, or a termination by Lessor, shall not work a
       merger, and shall, at the option of Lessor, terminate all or any existing
       subtenancies or may, at the option of Lessor, operate as an assignment to
       Lessor of any or all of such subtenancies.

36.    CONSENTS.  Except paragraph 33 hereof, wherever in this Lease the consent
       of one party is required to an act of the other party such consent shall
       not be unreasonably withhold or delayed.

37.    GUARANTOR.  In the event that there is a guarantor of this Lease, said
       guarantor shall have the same obligations as Lessee under this Lease.

38.    QUIET POSSESSION.  Upon Lessee paying the rent for the Premises and
       observing the performing all of the covenants, conditions and provisions
       on Lessee's part to be observed and performed hereunder, Lessee shall
       have quiet possession of the Premises for the entire term hereof subject
       to all of the provisions of this Lease.  The individuals executing this
       Lease on behalf of Lessor represent and warrant to Lessee that they are
       fully authorized the legally capable of executing this Lease on behalf of
       Lessor and that such execution is binding upon all parties holding an
       ownership interest in the Property.

39.    OPTIONS.

39.1   DEFINITION.  As used in this paragraph the work "Option" has the
       following meaning:  (1) the right or option to extend the term of this
       Lease or to renew this Lease or to extend or renew any lease that Lessee
       has on other property of Lessor; (2) the option or right of first refusal
       to lease the Premises or the right of first offer to lease the Premises
       or the right of first refusal to lease other space within the Industrial
       Center or other property of Lessor or the right of first offer to lease
       other space within the Industrial Center or other property of Lessor; (3)
       the right or option to purchase the Premises or the Industrial Center, or
       the right of first refusal to purchase the Premises or the Industrial
       Center, or the right of first offer to purchase the Premises or the
       Industrial Center, or the right or option to purchase other property of
       Lessor, or the right of first refusal to purchase other property of
       Lessor of the right of first offer to purchase other  property of Lessor.

39.2   OPTIONS PERSONAL.  Each Option granted to Lessee in this Lease is
       personal to the original Lessee and may be exercised only by the original
       Lessee while occupying the Premises who does so without the intent of
       thereafter assigning this Lease or subletting the Premises or any portion
       thereof, and may not be exercised or be assigned, voluntarily or
       involuntarily, by or to any Lessee Affiliate as defined in paragraph 12.2
       of this lease.  The Options, if any, herein granted to Lessee are not
       assignable separate and apart from this Lease, nor may any Option be
       separated from this Lease in any manner, either by reservation or
       otherwise.

39.3   MULTIPLE OPTIONS.  In the event that Lessee has any multiple options to
       extend or renew this Lease a later option cannot be exercised unless the
       prior option to extend or review this Lease has been so exercised.


39.4   EFFECT OF DEFAULT ON OPTIONS.

       (a)    Lessee Shall have no right to exercise an Option, notwithstanding
              any provision in the grant of Option to the contrary, (i) during
              the time commencing from the date Lessor gives to Lessee a notice
              of default pursuant to paragraph 13.1(b) or 13.1(c) and continuing
              until the noncompliance alleged in said notice of default is
              cured, or (ii) during the period of time commencing on the date
              after a monetary obligation to Lessor is due from Lessee and
              unpaid (without any necessity for notice thereof to Lessee) and
              continuing until the obligation is paid, or (iii) at any time
              after an event of default described in paragraphs 13.1 (d), or
              13.1(e) (without any necessity of Lessor to give



<PAGE>

              notice of such default to Lessee), nor (iv) in the event that
              lessor has given to Lessee three or more notices of default
              under  paragraph 13.1(b), or paragraph 13.1(c), whether or not
              the defaults are cured, during the 12 month period of time
              immediately prior to the time that Lessee attempts to exercise
              the subject Option.

       (b)    The period of time within which an Option may be exercised shall
              not be extended or enlarged by reason of Lessee's inability to
              exercise an Option because of the provisions of paragraph 39.4(a).

       (c)    All rights of Lessee under the provisions of an Option shall
              terminate and be of no further force or effect, notwithstanding
              Lessee's due and timely exercise of the Option, if, after such
              exercise and during the term of this Lease, (i) Lessee fails to
              pay to Lessor a monetary obligation of Lessee for a period of
              thirty (30) days after such obligation becomes due (without any
              necessity of Lessor to give notice thereof to Lessee), or (ii)
              Lessee fails to commence to cure a default specified in paragraph
              13.1(c)  within thirty(30) days after the date that lessor gives
              notice to Lessee of such default and/or Lessee fails thereafter to
              diligently prosecute said cure to completion, or (iii) Lessee
              commits a default described in paragraph 13.1(a), 13.1(d) or 13.1
              (e) (without any necessity of Lessor to give notice of such
              default to Lessee), or (iv) Lessor gives to Lessee three or more
              notices of default under paragraph 13.1(b), or paragraph 13.1 (c),
              whether or not the defaults are cured.

40.    SECURITIES MEASURES. Lessee hereby acknowledges that Lessor shall have no
       obligation whatsoever to provide guard service or other security measures
       for the benefit of the Premises or the Industrial Center.  Lessee assumes
       all responsibility for the protection of Lessee, its agents, and invitees
       and the property of Lessee and of Lessee's agents and invitees from acts
       of third parties.  Nothing herein contained shall prevent Lessor, at
       lessor's sole option, from providing security protection for the
       Industrial Center or any part thereof, in which event the cost thereof,
       in which event the cost thereof shall be included within the definition
       of Operating Expenses, as set forth in paragraph 4.2(b).

41.    EASEMENTS. Lessor reserves to itself the right, from time to time, to
       grant such easements, rights and dedications that Lessor deems necessary
       or desirable, and to cause the recordation of Parcel Maps and
       restrictions, so long as such easements, rights, dedications, Maps and
       restrictions do not unreasonably interfere with the use of the Premises
       by Lessee.  Lessee shall sign any of the aforementioned documents upon
       request of Lessor and failure to do so shall constitute a material
       default of this Lease by Lessee without the need for further notice to
       Lessee.

42.    PERFORMANCE UNDER PROTEST.  If at any time a dispute shall arise as to
       any amount or sum of money to be paid by one party to the other under the
       provisions hereof, the party against whom the obligation to pay the money
       is asserted shall have the right to make payment "under protest' and such
       payment shall not be regarded as a voluntary payment, and there shall
       survive the right on the part of said party to institute suit for the
       recovery of such sum.  If it shall be adjudged that there was no legal
       obligation on the part of said party to pay such sum or any part thereof,
       said party shall be entitled to recover such sum or so much thereof as it
       was not legally required to pay under the provisions of this Lease.

43.    AUTHORITY.  If Lessee is a corporation, trust, or general or limited
       partnership, each individual executing this Lease on behalf of such
       entity represents and warrants that he or she is duly authorized to
       execute and deliver this Lease on behalf of said entity.  If Lessee is a
       corporation, trust or partnership, Lessee shall, within thirty (30) days
       after execution of this Lease, deliver to lessor evidence of such
       authority satisfactory to Lessor.

44.    CONFLICT.  Any conflict between the printed provisions of this Lease and
       the typewritten or handwritten provision, if any, shall be controlled by
       the typewritten or handwritten provisions.



<PAGE>

45.    OFFER.  Preparation of this Lease by Lessor or Lessor's agent and
       submission of same to Lessee shall not be deemed an offer to lease.  This
       Lease shall become binding upon Lessor and Lessee only when fully
       executed by Lessor and Lessee.

46.    ADDENDUM.  Attached hereto is an addendum or addenda containing
       paragraphs A through H which constitue a part of this Lease.

47.    MODIFICATION FOR LENDER.  If in connection with obtaining financing for
       the building, the Lender shall request reasonable modifications in this
       Lease as a condition to such financing, Lessee will not unreasonably
       withhold, delay, or defer its consent thereto, provided that such
       modifications do not increase the obligations of Lessee hereunder or
       materially adverse affect the leasehold interest hereby created.

48.    LESSOR OPTION TO RELOCATE LESSEE.  At any time after Lessee's execution
       of this Lease, Lessor shall have the right, upon providing Lessee thirty
       (30) days notice in writing, to provide and furnish Lessee with space
       elsewhere in the building of approximately the same size as said
       Premises, and to move and place Lessee in such new space at Lessor's
       expense.  In the event Lessor moves Lessee to such new space, then this
       Lease and each and all of the terms and covenants and conditions hereof
       shall thereupon remain in full force and effect and be deemed applicable
       to such new space except that a revised Exhibit "A" shall become a part
       of this Lease and shall reflect the location of the new space and
       Paragraphs 4.1, 4.2, and 5 shall be amended to show correct data.  Should
       Lessee refuse to permit Lessor to move Lessee to such new space at the
       end of said thirty (30) day period, Lessor shall have the right to
       terminate this Lease by notice to such effect given to Lessee in writing
       within ten (10) days following the end of said thirty (30) day period,
       which termination shall be effective sixty (60) days after the date of
       the original relocation by Lessor.

49.    MORTGAGE PROTECTION.  Lessee agrees to give any mortgages and/or trust
       deed holders, as to all or a portion of the Premises, by registered mail,
       a copy of any notice of default served upon Lessor, provided that prior
       to such notice Lessee has been notified in writing (by way of notice or
       assignment of rents and leases, or otherwise) of the addresses of such
       mortgages an/or trust deed holders.  Lessee agrees not to exercise any
       remedies available by virtue of a default unless Lessor shall have failed
       to cure such default within thirty (30) days after receipt of notice of
       default or such additional time as may be reasonably necessary to cure
       the default in the case of a default incapable of being cured within
       thirty (30) days within which to cure such default, or if such default
       cannot be cured within that time, then such additional time as may be
       necessary if within such thirty (30) days any mortgagee and/or trust deed
       holder has commenced and is diligently pursuing the remedies necessary to
       cure such default (including but not limited to commencement of
       foreclosure proceedings if necessary to effect such cure), in which event
       such right, if any, as Lessee might otherwise have to terminate the Lease
       shall not be exercised while such remedies are being so diligently
       pursued.

8.1    LIABILITY INSURANCE-LESSEE.  Lessee shall, at Lessee's expense, obtain
       and keep in force during the term of this Lease a policy of Comprehensive
       General Liability insurance utilizing an Insurance Services Office
       standard form with Broad Form General Liability Endorsement (GLO404), or
       equivalent, in an amount of not less than 1)  $1,000,000 per occurrence
       of Bodily Injury and Property Damage combined single limit with a
       $1,000,000 excess liability policy, or 2)  $1,000,000 per occurrence of
       Bodily Injury and Property Damage with a $2,000,000 General Aggregate
       Bodily Injury and Property Damage, and shall insure Lessee with a Lessor
       as an additional insured against liability arising out of the use,
       occupancy or maintenance of the Premises.  The policy shall insure
       performance by Lessee of the indemnity provisions of this paragraph 8.
       The limits of said insurance shall not, however, limit the liability of
       Lessee hereunder.

                                 ADDENDUM TO LEASE


       This ADDENDUM is attached to and forms a part of that certain Standard
Industrial Lease dated for reference purposes AUGUST 30, 1999, by and between
William D & Edna J. Wright dba South Coast Business Park ("Lessor"), and
VALUECLICK, INC., A DELAWARE CORPORATION ("Lessee").  The said Standard
Industrial Lease is hereby modified/supplemented (and as
modified/supplemented is hereinafter referred to as "this Lease") in the
following particulars only:

       A.     OPTION TO EXTEND TERM OF LEASE.  Lessee is hereby granted the
option to extend the term of this Lease of  N/A  (     )  additional
successive periods of  N/A             (        )  years each.  The options
shall be exercised by the delivery of written notice to Lessor no earlier
than two hundred seventy (270) days an no later than one hundred eighty (180)
days prior to the expiration of the lease term then in effect.  Any
extentions granted hereunder shall be on the same terms and conditions
applicable to the initial term except as to rent, which shall be increased I
accordance with paragraph B(2) below.  Lessee's right to exercise the options
granted herein is subject to the terms and conditions set forth in paragraph
39 of this Lease.

       B.     ADJUSTMENT TO BASE RENT.
              (1)    Cost of Living Adjustments to Base Rent.  The Base Rent
payable pursuant to Paragraph 4.1 shall be subject to further adjustment as of
N/A,  and as of the same date each year thereafter during the initial lease term
and any extension period.  Said date is hereinafter referred to as the
"Adjustment Date."  The adjustment shall be made as follows:

              The Base Rent for the Premises shall be adjusted by the same
percentage as the increase, if any, in the Consumer Price Index (All Items
for All Urban Consumer 1982-84 = 100 Base), of the United States Department
of Labor, Bureau of Labor Statistics for Los Angeles-Anaheim-Riverside,  CA
(the "Index").  The adjustment shall be calculated according to the following
formula:

       X = A x B
               -
               C

       X = Adjusted rent

       A = Base Rent as of the first month of the term then in effect.

       B = The monthly index for the third month immediately preceding the
           Adjustment Date.

       C = The monthly index for the third month immediately preceding the first
           month of the term then in effect.

The month rent as so adjusted shall be payable for each month commencing with
the Adjustment Date and continuing until the next Adjustment Date.

If the Index is discontinued or revised during the term of this Lease, such
other government Index or computation with which it is replaced shall be used
in order to obtain substantially the same result as would be obtained if the
Index had not been discontinued or revised.



<PAGE>

       C.     USE.  Paragraph 6 of this Lease is hereby supplemented as follows:
(1)  Prohibited Uses.  Lessee shall not do or permit anything to be done in or
       about the Premises nor bring or keep anything therein which will in any
       way increase the existing rate of or affect any fire or other insurance
       upon the Premises or any of its contents, or cause a cancellation of any
       insurance policy covering the Premises or any part thereof or any of its
       contents.  Lessee shall not commit or suffer to be committed any nuisance
       or waste in or upon the Premises.  Lessee shall not use the Premises or

event of any of the occurrences listed in (g), and should such occurrence
continue for more than sixty (60) days, SoftAware or Client may terminate this
agreement with no future obligations to be incurred.

If SoftAware provides hardware to Client, SoftAware makes no actual warranty of
its own, but will pass through to the Client the manufacturers warranty to the
extent that such warranty is provided. In the even that Client discovers a
product to be defective, SoftAware will assist the buyer in notifying the
manufacturer of such defect.

Periodically, SoftAware will conduct routine scheduled maintenance of its

of any computer system connected to said network in any way; (d) Harassment,

Internet access, including but not limited to electronic mail; (e) Operating a
domain name server without SoftAware approval. Client agrees to adhere by
SoftAware's Acceptable Use Policy as detailed in Exhibit B and incorporated by
reference.

5.       INDEMNIFICATION

Client agrees to use the Internet Services in a manner permitted by applicable
local, state and federal laws. Client is prohibited from transmitting any

to, the use of copyrighted material without permission of the copyright holder,
material legally judged to be threatening or obscene, or material protected by
trade secret or trademark laws. Client agrees to indemnify and hold SoftAware

by use of the Internet Services. Client further agrees to indemnify and hold
SoftAware harmless from all lawsuits, judgments, decrees, cost and expenses, and
any attorney fees relating to Client's use of the Internet Services or breach of
this or other contracts.

6.       TERMINATION

any of the following reasons: protection of the integrity of its network; fraud;
willful misconduct; malfeasance; failure; neglect or refusal to perform duties
in any material respect; misfeasance or incompetence in any material respect;
violation of any law, rule or regulation (other than traffic violations or
similar minor infractions); material breach of any provision of this Agreement

Client agrees to compensate SoftAware for providing the services expressed in
this agreement in the amount of $13,000 per month. Client will receive up to ten
megabits per second for the $13,000 Internet Service fee. Client agrees to pay
an additional $950 per megabit per second if bandwidth usage exceeds the first

average of the usage for the month. SoftAware may delay billing on bandwidth
changes until all data relevant to said charges is collected and analyzed.
Monthly payments for each month will be due by the fifteenth day of the
preceding month.

Interest at a rate equal to the greater of one and three quarter percent (1.75%)
per month or the highest rate permissible under applicable law, accrued daily,

pay or reimburse SoftAware for any and all sales and use taxes, duties, or
levies imposed by any authority, government or government agency in connection
with the Internet Services, except property taxes and SoftAware's income taxes.

Should termination occur due to: (a ) client's non-payment of sums due under
this Agreement, or (b) Client's termination of SoftAware's service; then the
remainder of the amount due for the term of the contract shall be accelerated
and due on the date of termination, in addition to any other remedies which may
be applicable.

Client agrees that any equipment, facilities modification, or Client provided
infrastructure or services that remain in the service area or impound area for
more than sixty (60) days beyond termination, regardless of reason or ownership
of said items, shall be deemed to be abandoned and SoftAware shall have the
right to remove and or dispose of said equipment, modifications or
infrastructure or services at its sole discretion.

Client is hereby on notice the passing of a check on insufficient funds shall
subject Client to (1) the amount of the check, and (2) treble damages not less
than $100, and (3) a service charge payable to SoftAware for an amount not to
exceed twenty-five dollars for the first check, and thirty-five dollars for the
second check. After the second dishonored check, payment for services will take
the form of cashier's check, money order, or some other secured form of payment
deemed acceptable by SoftAware.

As additional security for the enforcement of this Agreement: Client grants
SoftAware a lien upon any material used or stored at SoftAware's facility.
Client warrants that may equipment stored under this Agreement is lawfully owned
by Client. If said equipment is not owned by Client, Client shall specify such
in writing to SoftAware, providing the name, address, and telephone number of
the legal owner, as well as any identification or invoice numbers necessary to
establish the correct identify of the products. Client shall also inform the
legal owner of the existence to this lien.

1. This agreement applies to the purchase of all services (collectively, the
"Services") ordered by Customer under this Agreement.

2. Customer shall pay the fees and other charges for each Service as provided
in this Agreement. VERIO reserves the right to change rates by notifying the
customer sixty (60) days in advance of the effective date of the change;
provided that VERIO shall not change rates during the term of any Term

location. Service charges shall be incvoiced monthly, and payment shall be
due on the date specified in the invoice ("Due Date"). Set-up and equipment
charges shall be invoiced upon acceptance of this Agreement by VERIO.
Customer will pay a late payment charge equal to 1.5% (or the highest amount
permitted by law, whichever is lower) per month or portion thereof on the
outstanding balance of any invoice remaining unpaid thirty (30) days after
the Due Date. Accounts unpaid thirty (30) days after the Due Date may have
service suspended or terminated. Such suspenison or termination shall not
relieve Customer of its obligation to pay the monthly fee. Customer agrees to
pay VERIO its reasonable expanses, including attorney's fees and collection
agency fees, incurred in enforcing its rights under this Agreement. Customer
shall pay all federal, state, and local state taxes assessed with respect to
the Services and the sale of equipment to Customer, except that taxesbased on

the end of the Term Commitment unless Customer provides ninety (90) days

early cancellation of a Term Commitment, Customer will be required to pay 75%
of VERIO's standard monthly charge for each month remaining in the Term
Commitment.

the Service which gave rise to such damages, losses and causes of actions
during the 12-month period prior to the date the damage or loss occurred or
the cause of the action arose. VERIO shall not be liable for failure or delay
in performing its obligations hereunder if such failure or delay is due to
circumstances beyond its reasonable control, including, without limitation,

consent of the parties; provided that the VERIO Acceptable Use Policy may be
amended form time-to-time by VERIO. No failure to exercise and no delay in
exercising any right, remedy, or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, remedy, or
power hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, or power provided herein or by law or in
equity. The waiver by any party of the time for performance of any act or
condition hereunder shall not constitute a waiver of the act or condition
itself. This Agreement shall be binding upon and inure to the benefit of the
parties and successors, and assigns. Customer may not assign this Agreement
without the prior consent of VERIO. If any provision of this Agreement
without the prior written consent of VERIO. If any provision of this Agreement

agreements and shall prevail notwithstanding any variance with the terms and
conditions of any order submitted. Acceptance of this Agreement by VERIO may be
subject, in VERIO's absolute discretion, to satisfactory completion of a credit
check. Activation of service shall indicate VERIO's acceptance of this
Agreement. Use of the VERIO Network constitutes acceptanxce of this agreement.

                SERVICE LEVEL AGREEMENT: AVAILABILITY GUARANTEE


Verio guarantees to have the Verio available to the Client for 99.9% of the
time. Verio will credit Client's account if Verio fails to meet this
availability guarantee during any given calendar month. "Network Unavailability"
consists of the number of minutes that the Verio network is not available to the
Client, but does not include unavailability continuing for an hour of less which
Client fails to report to Verio within 3 business days.

Client shall not receive any credit if Network Unavailability is:

         (a) caused by Client's applications, equipment or facilities;
         (b) caused by negligence, willful misconduct, or the use of the Verio
             services in breach of Verio's Terms and Conditions and Acceptable
             Use Policy, by Client or others authorized by Client;
         (c) due to a failure of power, facilities, equipment, applications,
             systems or connections not provided by Verio;
         (d) caused by the failure of access circuits to Verio's network, unless
             such failure is solely caused by Verio;
         (e) a result of scheduled Verio maintenance;
         (f) associated with DNS issues outside the direct control of Verio;
         (g) a result of other National networks/exchanges that adversely affect
             the ability to pass IP traffic on the Internet as a whole; or
         (h) for any reason beyond the control of Verio.

In the event that Verio's Network Availability is less than 99.9% uptime in any
calendar month, Verio will provide a credit on its IP charges to Client. For
every hour, or fraction thereof, of Network unavailability as defined above, a
credit for one day's pro-rated service will be applied to the next monthly
invoice. This amount shall not exceed 7 day's credit for any outage(s) during
any single 24-hour period. Total credits for any outage(s) in any calendar month
will not exceed the amount of the client's regular monthly bill for IP services.

                               LATENCY GUARANTEE

Verio will guarantee the latency for average round-trip transmission times
between Verio designated backbone routers located in California and the East
Coast. "Average Latency" is defined as the average of samples taken between the
specified backbone routers during a calendar month. In the event that the
Average Latency exceeds 100 milliseconds during a calendar month, Verio will
provide a credit on its IP charges for one day's pro-rated service on the next
monthly invoice.
