                                  THE COMPANY
   
  GeoCities offers the world's largest and one of the fastest growing
communities of personal Web sites on the Internet. GeoCities pioneered the
first large-scale, Web-based community for Internet users to express
themselves, share ideas, interests and expertise, and publish content
accessible to other users with common interests. The mainstay of the Company's
community are its "Homesteaders," Internet users who create their own personal
Web sites or "Homesteads" in themed "neighborhoods" on the GeoCities Web site.
These neighborhoods provide a context for Web users to publish content, to
share experiences and ideas with other users and to access a centralized and
easy-to-navigate destination for user-published content. With thousands of new
Homesteaders joining each day, the GeoCities community has grown from
approximately 10,000 Homesteads in October 1995 to over 2.1 million in July
1998. Homesteaders have created an estimated 17 million pages of personalized
content, attracting over 14.8 million unique visitors to, and generating over
925 million page views on, the GeoCities Web site, according to Relevant
Knowledge in June 1998 and Nielsen I/Pro in May 1998, respectively. GeoCities
was the third most trafficked Web site on the Internet among home users in June
1998, according to Media Metrix, and, based on this information, the Company
believes it was the most popular community of personal Web sites on the
Internet during the first two quarters of 1998. This combination of GeoCities'
distinctive community context, topical organization and high volume of traffic
provides advertisers and businesses with an attractive platform for targeted
Web advertising and Web commerce.     
 
  As the Internet continues to grow, Web users, advertisers and businesses are
increasingly seeking online communities. Users are seeking from the Web the
same opportunity for expression, interaction, sharing and recognition that they
seek in the everyday world. To date, a typical Internet user's experience
surfing the Web has been essentially one-way--searching and viewing Web sites
containing professionally created content on topics of general interest, such
as current events, sports, finance, politics and weather. In general, the Web
does not provide a context to publish, promote, search, view and react to
personal content. While Internet search and navigational sites have improved a
user's ability to seek out aggregated Web content, these sites are not
primarily focused on providing a robust platform for publishing or aggregating
the rapidly increasing volume of personalized content created by users with
similar interests, or enabling such users to interact with one another.
Similarly, users browsing the Web are increasingly seeking ways of accessing
unique, personalized content, and interacting and communicating with other
individuals with similar interests. Often the most relevant content for a user
is that generated by other users who share a common interest. Online
communities offer a centralized means of accessing diverse, user-created
content in an easy-to-navigate context
 
                                       3
<PAGE>
 
and the ability to interact directly with the author of such personalized
content. For advertisers and businesses, online communities hold the potential
of reaching highly targeted audiences within a more personalized context, thus
providing the opportunity to increase advertising efficiency and improve the
likelihood of a sale.
   
  GeoCities offers Web users the ability to join and become actively involved
in the world's largest Web community of personal Web sites. GeoCities provides
Web users with free disk space and publishing tools to quickly and easily
create their own sites in one of over 40 topically organized neighborhoods,
such as CapitolHill for politics, Colosseum for sports, Hollywood for movies
and television and WallStreet for finance. Homesteaders are encouraged to
become active participants in the GeoCities community by updating their sites
and communicating with others through free e-mail, chat and bulletin-board
services provided by the Company. The Company offers Homesteaders seeking
greater involvement the opportunity to join the ranks of over one thousand
active Community Leaders and Community Liaisons--volunteers who welcome
Homesteaders and provide them with assistance, suggest improvements to
GeoCities and monitor the GeoCities community for compliance with community
guidelines. In addition, the Company seeks to make the GeoCities community a
primary destination point for Internet users seeking personalized, user-created
content. Through the Company's enhanced user interface, GeoCities provides a
central site for Internet users to quickly access and view millions of pages of
topically organized content created by fellow users. This distinct community
context and high volume of traffic attracts advertisers, vendors and third-
party content providers from whom the Company derives revenue from advertising
and online commerce. For the six months ended June 30, 1998, the Company had
approximately 170 advertising customers, including Acura, IBM, Microsoft and
VISA, and four premier commerce partners, including Amazon.com, CDnow, First
USA and Surplus Direct/Egghead. The Company's equity investors include Chase
Capital Partners, CMG@Ventures, Intel Corporation, SOFTBANK Holdings Inc. and
Yahoo! Inc.     
   
  The Company's objective is to be the world's leading member-created online
community for Web users. The Company's strategy includes: (i) expanding its
Homesteader base and strengthening Homesteader affinity through the
introduction of new classes of membership, more advanced and easier-to-use
publishing tools and affinity-building programs; (ii) building the GeoCities
brand; (iii) enhancing the GeoCities site functionality and performance through
continued investments in technology and site infrastructure; (iv) expanding
globally, through initiatives similar to its current GeoCities Japan
Corporation joint venture with SOFTBANK Corporation of Japan and
(v) establishing additional strategic relationships, such as its current
distribution relationship with Yahoo! Inc. The Company believes that this
strategy will result in a highly scalable business platform from which it can
generate revenues from multiple sources, including advertising, commerce and
premium membership services. The Company does not generate revenues from
general Internet access or subscription fees.     
   
  The Company was incorporated under the laws of California in December 1994
and intends to reincorporate in Delaware in July 1998. Unless the context
otherwise requires, references in this Prospectus to the "Company" or
"GeoCities" refer to GeoCities, a Delaware corporation and its predecessor
California corporation. The Company's principal executive offices are located
at 1918 Main Street, Suite 300, Santa Monica, California 90405. Its telephone
number at that location is (310) 664-6500.     
 
  GeoCities is a registered service mark of the Company. GeoPlus, GeoPoints,
GeoRewards, GeoShops and GeoTickets are service marks of the Company. This
Prospectus contains other product names, trade names, service marks and
trademarks of the Company and of other organizations, all of which are the

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves a high
degree of risk. The following factors, in addition to the other information
contained in this Prospectus, should be carefully considered in evaluating the
Company and its business before purchasing the Common Stock offered hereby.
This Prospectus contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain
factors, including those set forth in the following risk factors and elsewhere
in this Prospectus.
 
LIMITED OPERATING HISTORY; NO ASSURANCE OF PROFITABILITY; ANTICIPATED LOSSES
   
  The Company was founded in December 1994, but did not begin generating
advertising revenues until mid-1996. For 1997 and the six months ended June
30, 1998, the Company generated revenues of $4.6 million and $5.5 million,
respectively. Accordingly, the Company has a limited operating history upon
which an evaluation of the Company, its current business and prospects can be
based. In addition, the Company's revenue model is evolving and relies
substantially upon the sale of advertising on its Web site. The Company's
business must be considered in light of the risks, expenses and problems
frequently encountered by companies in their early stages of development,
particularly companies in new and rapidly evolving markets such as the
Internet. Specifically, such risks include, without limitation, the inability
of the Company to maintain and increase levels of traffic on the GeoCities Web
site, the failure by the Company to continue to develop and extend the
GeoCities brand, the inability of the Company to meet minimum guaranteed
impressions under advertising agreements, the lack of broad acceptance of the
community model on the Internet, the inability of the Company to attract or
retain members, acceptance by Homesteaders of advertising on Homesteads, the
inability of the Company to generate significant Web-based commerce revenues
or premium service revenues from its members, the failure of the Company to
anticipate and adapt to the developing Internet market, the failure of its
server and networking systems to efficiently handle the Company's Web traffic,
changes in laws that adversely affect the Company's business, competition, the
inability to effectively manage rapidly expanding operations, dependence on
the Internet, the introduction and development of different or more extensive
communities by direct and indirect competitors, particularly in light of the
fact that many of such competitors are much larger and have greater financial,
technical and marketing resources than the Company, the failure of the Web to
achieve broad acceptance as an advertising and commercial medium, reductions
in market prices for Web-based advertising as a result of competition or
otherwise, the inability of the Company to maintain or achieve higher rates
for advertising, the inability of the Company to identify, attract, retain and
motivate qualified personnel, other risks noted in this section of the
Prospectus, and general economic conditions. There can be no assurance that
the Company will be successful in addressing such risks, and any failure to do
so could have a material adverse effect on the Company's business, results of
operations and financial condition.     
   
  As of June 30, 1998, the Company had an accumulated deficit of $19.7
million. Although the Company has experienced revenue growth in recent
periods, there can be no assurance that the revenues of the Company will
continue at their current level or increase in the future. The Company has not
achieved profitability on a quarterly or annual basis to date, and the Company
anticipates that it will incur net losses for the foreseeable future. The
extent of these losses will be contingent, in part, on the amount of growth in
the Company's revenues from advertising, commerce and premium membership
service fees. The Company expects its operating expenses to increase
significantly, especially in the areas of sales and marketing and brand
promotion, and, as a result, will need to generate increased quarterly
revenues to achieve profitability. The extremely limited operating history of
the Company makes the prediction of future results of operations difficult or
impossible, and, therefore, the recent revenue growth experienced by the
Company should not be taken as an     
 
                                       6
<PAGE>
 
indication of the rate of revenue growth, if any, that can be expected in the
future. The Company believes that period-to-period comparisons of its
operating results are not meaningful and that the results for any period
should not be relied upon as an indication of future performance. To the
extent that revenues do not grow at anticipated rates or that increases in its
operating expenses precede or are not subsequently followed by commensurate
increases in revenues, or that the Company is unable to adjust operating
expense levels accordingly, the Company's business, results of operations and
financial condition will be materially and adversely affected. There can be no
assurance that the Company's operating losses will not increase in the future
or that the Company will ever achieve or sustain profitability.
 
POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS; UNPREDICTABILITY OF FUTURE
REVENUES; SEASONALITY
   
  The Company's operating results may fluctuate significantly in the future as
a result of a variety of factors, many of which are outside of the Company's
control. These factors include demand for Web-based advertising, acceptance of
the Web as an advertising medium, the level of traffic on the GeoCities Web
site, the advertising budgeting cycles of advertisers, the amount and timing
of capital expenditures and other costs relating to the expansion of the
Company's operations, the introduction of new or enhanced services by the
Company or its competitors, the timing and number of new hires, pricing
changes for Web-based advertising as a result of competition or otherwise, the
loss of a key advertising contract or relationship by the Company, changes in
the Company's pricing policy or those of its competitors, the mix of types of
advertisements sold by the Company, engineering or development fees that may
be paid in connection with adding new Web site development and publishing
tools, technical difficulties with the GeoCities Web site, incurrence of costs
relating to future acquisitions, general economic conditions, and economic
conditions specific to the Internet or all or a portion of the technology
sector. As a strategic response to changes in the competitive environment, the
Company may from time to time make certain pricing, service or marketing
decisions or business combinations that could have a material adverse effect
on the Company's business, results of operations and financial condition. In
order to accelerate the promotion of the GeoCities brand, the Company intends
to significantly increase its marketing budget. A substantial increase in
marketing expenditures will have a negative impact on the Company's results of
operations for a number of quarterly periods. The Company has experienced, and
expects to continue to experience, seasonality in its business, with user
traffic on the GeoCities Web site being lower during the summer and year-end
vacation and holiday periods when overall usage of the Web is lower.
Additionally, seasonality may significantly affect the Company's advertising
revenues during the first and third calendar quarters, as advertisers
historically spend less during these periods. Because Web-based advertising is
an emerging market, additional seasonal and other patterns in Web advertising
may develop in the future as the market matures, and there can be no assurance
that such patterns will not have a material adverse effect on the Company's
business, results of operations and financial condition.     
   
  As a result of the Company's limited operating history, the Company has
limited meaningful historical financial data upon which to base planned
operating expenses. Accordingly, the Company's expense levels are based in
part on its expectations as to future revenues from advertising, commerce
revenue-sharing arrangements, premium membership service fees and its
anticipated growth in memberships and to a large extent are fixed. There can
be no assurance that the Company will be able to accurately predict its
revenues, particularly in light of the intense competition for the sale of
Web-based advertisements, revenue-sharing opportunities and new members, the
Company's limited operating history and the uncertainty as to the broad
acceptance of the Web as an advertising and commerce medium. Any failure by
the Company to accurately predict revenues in relation to fixed-expense levels
could have a material adverse effect on the Company's business, results of
operations and financial condition.     
 
  The Company derives a significant portion of its revenues from the sale of
advertising under short-term contracts, averaging one to two months in length.
As a result, the Company's quarterly
 
                                       7
<PAGE>
 
   
revenues and operating results are, to a significant extent, dependent on
advertising revenues from contracts entered into within the quarter, as well
as on the Company's ability to adjust spending in a timely manner to
compensate for any unexpected revenue shortfall. To date, a significant
portion of the Company's revenues in any given period have been derived from a
small group of customers, the composition of which generally changes from
period to period. The Company expects this situation to continue in the
future. The Company's largest customer, Egghead, Inc. ("Surplus
Direct/Egghead"), accounted for approximately 12% and 10% of the Company's net
revenues during 1997 and the six months ended June 30, 1998, respectively. The
Company's four largest customers during 1997 and the six months ended June 30,
1998, including Surplus Direct/Egghead, which were, other than Surplus
Direct/Egghead, different customers in both of such periods, accounted for
approximately 29% and 28%, respectively, of the Company's net revenues in such
periods. The cancellation or deferral of existing advertising or commerce
contracts or the failure to obtain new contracts in any quarter could
materially and adversely affect the Company's business, results of operations
and financial condition for that quarter and future periods. Furthermore, the
Company's advertising revenues are based in part on the amount of traffic on
the GeoCities Web site. Accordingly, any significant shortfall in traffic on
the GeoCities Web site in relation to the Company's expectations or the
expectations of existing or potential advertisers would have a material
adverse effect on the Company's business, results of operations and financial
condition. In addition, substantially all of the Company's advertising
contracts require the Company to guarantee a minimum number of impressions. In
the event that these minimum impressions are not met, the Company could be
required to provide credit for additional impressions and the ability of the
Company to sell advertising to new or existing advertisers could be adversely
affected, and the Company could be forced to reduce advertising rates.     
   
  A key element of the Company's strategy is to generate revenues through
revenue-sharing relationships with commerce partners in addition to selling
standard banner advertising. The Company currently has short-term agreements
with four premier commerce partners: Amazon.com, CDnow, First USA and Surplus
Direct/Egghead. Under the terms of these agreements, the Company has agreed to
limit the number of such premier commerce partners on its Web site to four and
certain other restrictions. Each of these agreements is renewable at the
option of the other party, subject to the payment of certain renewal fees and
rates. To date, the revenues received by the Company under the revenue-sharing
portions of these arrangements have not been material, and there can be no
assurance that the Company will receive a material amount of revenue under
these agreements in the future. The Company's agreement with Surplus
Direct/Egghead allows Surplus Direct/Egghead to terminate its agreement with
the Company upon 30 days notice, subject to the payment of certain termination
fees. Moreover, there can be no assurance that any of these parties will
exercise its renewal right or that Surplus Direct/Egghead will not exercise
its right to terminate its agreement with the Company, either of which events
could have a material adverse effect on the Company's business, results of
operations and financial condition. In addition, under the terms of its
agreement with First USA, the Company is obligated to generate a certain
number of accepted credit-card applications, and, if the Company fails to
generate such applications, it is generally required to increase the amount of
advertising it provides to First USA on its site. There can be no assurance
that this provision will not have a material adverse effect on the Company's
business, results of operations and financial condition.     
 
  Due to any of the foregoing factors, in some future quarter or quarters the
Company's operating results may fall below the expectations of securities
analysts and investors. In such event, the trading price of the Company's
Common Stock would likely be materially and adversely affected.
 
UNPROVEN BUSINESS MODEL; DEPENDENCE ON MEMBERS
 
  The Company's business model depends upon its ability to leverage its
community platform and generate multiple revenue streams. The potential
profitability of this business model is unproven, and, to be successful, the
Company must, among other things, develop and market solutions that achieve
 
                                       8
<PAGE>
 
   
broad market acceptance by its members, Internet advertisers, commerce vendors
and Internet users. Under the Company's model, the Company is substantially
dependent upon its member-generated content, the grass-roots promotional
efforts of its members, the acceptance by its members of advertising and other
promotional programs of third parties and the Company, including the Company's
recently introduced watermark on Homesteads, and the voluntary involvement of
its Community Leaders and Liaisons to attract Web users to its site and to
reduce the demands on Company personnel. This model has existed for only a
limited period of time, and, as a result, is relatively unproven. There can be
no assurance that the Company's member-generated content or the promotional
efforts of its members will continue to attract users to the Company's Web
site. There can also be no assurance that the Company's Community Leaders and
Liaisons will continue to devote their time voluntarily to improving the
community, or, given the fact that the Company provides free disk space to its
Homesteaders and the Company supports the involvement of its Community Leaders
and Liaisons, that third parties will not attempt to hold the Company
responsible for such content and/or any actions or omissions of such Community
Leaders and Liaisons. There also can be no assurance that the Company's
business, results of operations and financial condition would not be
materially and adversely affected if a substantial number of Homesteaders
became dissatisfied with the Company's services or its focus on the
commercialization of those services. Moreover, there can be no assurance that
community on the Internet or the Company's services and brand will achieve
broad market acceptance. Accordingly, no assurance can be given that the
Company's business model will be successful or that it can sustain revenue
growth or generate significant profits.     
 
RELIANCE ON ADVERTISING REVENUES AND UNCERTAIN ADOPTION OF THE WEB AS AN
ADVERTISING MEDIUM
   
  The Company has derived a substantial majority of its revenues to date from
the sale of advertisements, including banner advertising revenues and
advertising revenues from its premier commerce partners. For 1997 and the six
months ended June 30, 1998, advertising revenues represented 90.6% and 90.2%,
respectively, of the Company's net revenues. The Company's strategy is to
continue to emphasize advertising as a method of generating revenues. The
Company's current business model is therefore highly dependent on the amount
of traffic on the Company's Web site. This type of business model, however, is
relatively unproven. The Internet as an advertising medium has not been
available for a sufficient period of time to gauge its effectiveness as
compared with traditional advertising media. Many of the Company's advertisers
have only limited experience with the Web as an advertising medium, have not
yet devoted a significant portion of their advertising budgets to Web-based
advertising and may not find such advertising to be effective for promoting
their products and services relative to traditional print and broadcast media.
For 1997, advertising on the Web represented less than 0.5% of overall
advertising revenues in the United States according to industry sources. The
Company's ability to generate significant advertising revenues will also
depend on, among other things, the development of a large base of users of the
Company's services possessing demographic characteristics attractive to
advertisers and the ability of the Company to develop or acquire effective
advertising delivery and measurement systems.     
 
  The adoption of Web-based advertising, particularly by those entities that
have historically relied upon traditional media for advertising, requires the
acceptance of a new way of conducting business and exchanging information.
Entities that already have invested substantial resources in other methods of
conducting business may be reluctant to adopt a new strategy that may limit or
compete with their existing efforts. There can be no assurance that the market
for Web advertising will continue to emerge or become sustainable. If the
market develops more slowly than expected, the Company's business, results of
operations and financial condition could be materially and adversely affected.
No standards have been widely accepted for the measurement of the
effectiveness of Web-based advertising, and there can be no assurance that
such standards will develop sufficiently to support the Web as an effective
advertising medium. There can be no assurance that advertisers will accept the
Company's or other third-party measurements of impressions, which could have a
material adverse effect on the Company's business, results of operations and
financial condition. In addition, there is intense
 
                                       9
<PAGE>
 
competition in the sale of advertising on the Web resulting in a wide variety
of pricing models, rate quotes and advertising services, making it difficult
to project future levels of advertising revenues and rates. It is also
difficult to predict which pricing models, if any, will achieve broad
acceptance among advertisers. The Company has traditionally based its
advertising rates on providing advertisers with a guaranteed number of
impressions, and any failure of the Company's advertising model to achieve
broad market acceptance would have a material adverse effect on the Company's
business, results of operations and financial condition.
   
  The process of managing advertising within a large, high-traffic Web site
such as the Company's is an increasingly important and complex task. The
Company licenses from IMGIS, Inc. ("IMGIS") its advertising management system
(the "AdForce service"). Under the license agreement, IMGIS provides the
Company an Internet advertising administration system to facilitate the
Company's management of advertising on its Web site. The Adforce service is
intended to permit the Company to generate ad tags, schedule advertising to
run in the online environments in which the Company places the ad tags and
generate reports on such advertising. The IMGIS agreement is for a term of two
years and will expire in May 2000, subject to the Company's right to terminate
the agreement with or without cause during the 30-day period following May 4,
1999. Additionally, the Company may terminate the agreement for IMGIS' non-
performance under the agreement. No assurance can be given that the Company
will not elect to terminate the agreement. If it elected to do so, the Company
believes that it could replace the Adforce service with other available
advertising management systems. However, any such termination and replacement
could disrupt the Company's ability to manage its advertising operations for a
period of time. In addition, to the extent that the Company encounters system
failures or material difficulties in the operation of this system, the Company
could be unable to deliver banner advertisements and sponsorships through its
Web site. Any extended failure of, or material difficulties encountered in
connection with, the Company's advertising management system may expose the
Company to "make good" obligations with its advertisers, which, by displacing
saleable advertising inventory, among other consequences, would reduce
revenues and have a material adverse effect on the Company's business, results
of operations and financial condition.     
 
  There can be no assurance that current advertisers will continue to purchase
advertising space and services from the Company at current levels or at all,
or that impressions sufficient to generate revenues will be achieved, or that
the Company will be able to successfully attract additional advertisers.
Furthermore, with the rapid growth of available advertising inventory on the
Internet and the intense competition among sellers of advertising space, it is
difficult to project pricing models that will be adopted by the industry or
individual companies. The Company's ability to generate significant
advertising revenues will depend, in part, on the ability of the Company to
leverage additional platforms within its community for new advertising
programs without diluting the perceived value of its existing programs.
Moreover, "filter" software programs that limit or remove advertising from a
Web user's desktop are available; widespread adoption or increased use of such
software by users could have a material adverse effect upon the viability of
advertising on the Web and on the Company's business, results of operations
and financial condition. There can be no assurance that the Company will be
successful in generating significant future advertising revenues or other
source of revenues, and any failure to do so would have a material adverse
effect on the Company's business, results of operations and financial
condition.
 
MANAGEMENT OF GROWTH AND RELATIONSHIPS; BRIEF TENURE OF MANAGEMENT; DEPENDENCE
ON KEY PERSONNEL
 
  The Company has experienced and may continue to experience rapid growth,
which has placed, and could continue to place, a significant strain on the
Company's managerial, financial and operational resources. The Company is
required to manage multiple relationships with various strategic partners,
technology licensors, members, advertisers and other third parties. These
requirements will be exacerbated in the event of further growth of the Company
or in the number of third party relationships, and there can be no assurance
that the Company's systems, procedures or controls will be adequate to support
the Company's operations or that Company management will be
 
                                      10
<PAGE>
 
   
able to manage any growth effectively. To effectively manage its potential
growth, the Company must continue to implement and improve its operational,
financial and management information systems and to expand, train and manage
its employee base. As of June 30, 1998, the Company had grown to 152 full-time
employees from 63 on June 30, 1997, and the Company anticipates that the
number of its employees will increase significantly in the next 12 months. The
Company has recently hired a substantial number of its existing executive
officers to establish a management infrastructure to manage the potential
growth of its business, including its Chief Executive Officer (May 1998),
Chief Financial and Chief Operating Officer (November 1997), Vice President,
Advertising Sales (September 1997), Vice President, Marketing (May 1998), Vice
President, Business Development (May 1998) and Vice President, Human Resources
(June 1998). In certain cases, these executives replaced existing executive
officers, but in all other cases were added to fill newly-created positions in
response to the Company's expanding operations. These individuals have not
previously worked together and are in the process of integrating as a
management team, and there can be no assurance that they will be able to work
together effectively or successfully manage any growth experienced by the
Company. Certain of the Company's new executives lack experience in an
Internet industry environment and, accordingly, there can be no assurance that
they will quickly adapt to the Internet marketplace. In addition, the majority
of the Company's sales personnel have recently joined the Company, and there
can be no assurance that they will be successful in increasing the Company's
level of sales.     
   
  The Company's performance is substantially dependent on the performance of
its executive officers and other key employees. The Company does not currently
have "key person" life insurance policies on any of its employees, other than
on David Bohnett, the Company's Chairman and founder. The loss of the services
of any of its executive officers or other key employees could have a material
adverse effect on the business, results of operations and financial condition
of the Company. Competition for senior management, experienced media sales and
marketing personnel, qualified Web engineers and other employees is intense,
and there can be no assurance that the Company will be successful in
attracting and retaining such personnel. The Company has experienced
difficulty from time to time in hiring and retaining the personnel necessary
to support the growth of its business, and there can be no assurance that the
Company will not experience similar difficulty in the future. The failure of
the Company to successfully manage its personnel requirements would have a
material adverse effect on the Company's business, results of operations and
financial condition.     
 
INTENSE COMPETITION
   
  The market for members, visitors and Internet advertising is new and rapidly
evolving, and competition for members, visitors and advertisers is intense and
is expected to increase significantly in the future. Barriers to entry are
relatively insubstantial. The Company believes that the principal competitive
factors for companies seeking to create community on the Internet are critical
mass, functionality, brand recognition, member affinity and loyalty, broad
demographic focus and open access for visitors. Other companies who are
primarily focused on creating Web-based community on the Internet are Tripod,
Inc., a subsidiary of Lycos, Inc. ("Tripod/Lycos"), Angelfire Communications
("Angelfire"), Xoom, Inc. ("Xoom") and theglobe.com ("theglobe"). The Company
will likely also face competition in the future from Web directories, search
engines, shareware archives, content sites, commercial online service
providers ("OSPs"), sites maintained by Internet service providers ("ISPs")
and other entities that attempt to or establish communities on the Internet by
developing their own community or acquiring one of the Company's competitors.
In addition, the Company could face competition in the future from traditional
media companies, a number of which, including Disney, CBS and NBC, have
recently made significant acquisitions of or investments in Internet
companies. Further, there can be no assurance that the Company's competitors
and potential competitors will not develop communities that are equal or
superior to those of the Company or that achieve greater market acceptance
than the Company's community. The Company also competes for visitors with many
    
                                      11
<PAGE>
 
   
Internet content providers and ISPs, including Web directories, search
engines, shareware archives, content sites, commercial online services and
sites maintained by Internet service providers, as well as thousands of
Internet sites operated by individuals and government and educational
institutions. These competitors include free information, search and content
sites or services, such as America Online, Inc. ("AOL"), CNET, Inc. ("CNET"),
CNN/Time Warner, Inc. ("CNN/Time Warner"), Excite, Inc. ("Excite"), Infoseek
Corporation ("Infoseek"), Lycos, Inc. ("Lycos"), Netscape Communications
Corporation ("Netscape"), Microsoft Corporation ("Microsoft") and Yahoo! Inc.
("Yahoo!") some of whom, such as Yahoo! and Lycos, may also have relationships
with GeoCities. The Company also competes with the foregoing companies, as
well as traditional forms of media such as newspapers, magazines, radio and
television, for advertisers and advertising revenues. The Company believes
that the principal competitive factors in attracting advertisers include the
amount of traffic on its Web site, brand recognition, customer service, the
demographics of the Company's members and viewers, the Company's ability to
offer targeted audiences and the overall cost-effectiveness of the advertising
medium offered by the Company. The Company believes that the number of
Internet companies relying on Web-based advertising revenue will increase
substantially in the future. Accordingly, the Company will likely face
increased competition, resulting in increased pricing pressures on its
advertising rates which could in turn have a material adverse effect on the
Company's business, results of operations and financial condition.     
 
  Many of the Company's existing and potential competitors, including Web
directories and search engines and large traditional media companies, have
longer operating histories in the Web market, greater name recognition, larger
customer bases and significantly greater financial, technical and marketing
resources than the Company. Such competitors are able to undertake more
extensive marketing campaigns for their brands and services, adopt more
aggressive advertising pricing policies and make more attractive offers to
potential employees, distribution partners, commerce companies, advertisers
and third-party content providers. There can be no assurance that Internet
content providers and ISPs, including Web directories, search engines,
shareware archives, sites that offer professional editorial content,
commercial online services and sites maintained by ISPs will not be perceived
by advertisers as having more desirable Web sites for placement of
advertisements. In addition, substantially all of the Company's current
advertising customers and strategic partners also have established
collaborative relationships with certain of the Company's competitors or
potential competitors, and other high-traffic Web sites. Accordingly, there
can be no assurance that the Company will be able to grow its membership base,
traffic levels and advertiser customer base at historical levels or retain its
current members, traffic levels or advertiser customers, or that competitors
will not experience greater growth in traffic than the Company as a result of
such relationships which could have the effect of making their Web sites more
attractive to advertisers, or that the Company's strategic partners will not
sever or will elect not to renew their agreements with the Company. There can
also be no assurance that the Company will be able to compete successfully
against its current or future competitors or that competition will not have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
RISK OF CAPACITY CONSTRAINTS; SYSTEM FAILURES; TECHNOLOGICAL RISKS
   
  The performance of the Company's server and networking hardware and software
infrastructure is critical to the Company's business and reputation and its
ability to attract Web users, advertisers, new members and commerce partners
to the Company's Web site. Any system failure that causes an interruption in
service or a decrease in responsiveness of the Company's Web site could result
in less traffic on the Company's Web site and, if sustained or repeated, could
impair the Company's reputation and the attractiveness of its brand name. The
Company maintains redundant systems for all critical operational areas. If
necessary, connectivity through a failed router or switch can be restored via
one of the hot standby systems maintained on site. Moreover, the Company
maintains redundant application servers and databases to ensure full
functionality in the event of a system failure. Disk storage is     
 
                                      12
<PAGE>
 
   
configured to survive multiple drive failures without risk of data loss. To
ensure backup and restoration of all production data, the Company's system is
comprised of several dedicated servers and tape libraries with the capacity to
backup the Web site every 24 hours. Backup media is rotated into offsite
archives to ensure data integrity should catastrophic events occur on site.
    
   
  The Company entered into a one-year Web-hosting agreement with Exodus
Communications, Inc. ("Exodus") in November 1997. This agreement is
automatically renewed for subsequent one-year terms unless either party
provides notice at least 90 days prior to the expiration of any term. Pursuant
to the agreement, Exodus provides and manages power and environmentals for the
Company's networking and server equipment. Exodus also provides site
connectivity to the Internet via multiple DS-3 and OC-3 links on a 24 hour-a-
day, seven days per week basis. In the event that the Company's Internet
connectivity is interrupted due to reasons within Exodus' reasonable control,
Exodus must in general provide the Company with additional access at no
charge. Under the terms of the agreement, Exodus does not, however, guarantee
that the Company's Internet access will be uninterrupted, error-free or
completely secure. Any disruption in the Internet access provided by Exodus or
any failure of the Company's server and networking systems to handle current
or higher volumes of traffic could have a material adverse effect on the
Company's business, results of operations and financial condition. An increase
in the use of the Company's Web site could strain the capacity of its systems,
which could lead to slower response time or system failures. Slowdowns or
system failures adversely affect the speed and responsiveness of the Company's
Web site and would diminish the experience for the Company's members and
visitors and reduce the number of impressions received by advertisers, and,
thus, could reduce the Company's advertising and commerce revenues. The
ability of the Company to provide effective Internet connections or of its
systems to manage substantially larger numbers of customers at higher
transmission speed is as yet unknown, and, as a result, the Company faces
risks related to its ability to scale up to its expected customer levels while
maintaining superior performance. If GeoCities' usage of bandwidth increases,
GeoCities will need to purchase additional servers and networking equipment
and rely more heavily on its equipment and on Exodus and its services to
maintain adequate data transmission speeds, the availability of which may be
limited or the cost of which may be significant.     
   
  The successful delivery of the Company's services is also dependent in
substantial part upon the ability of Exodus and the Company to protect
GeoCities' servers and network infrastructure against damage from human error,
fire, flood, power loss, telecommunications failure, sabotage, intentional
acts of vandalism and similar events. In addition, substantially all of the
Company's servers and network infrastructure are located in Northern
California, an area susceptible to earthquakes, which also could cause system
outages or failures if one should occur. Despite precautions taken by and
planned to be taken by the Company and Exodus, the occurrence of other natural
disasters or other unanticipated problems at their respective facilities could
result in interruption in the services provided by the Company or significant
damage to GeoCities' equipment. Despite the implementation of network security
measures by the Company, its servers are vulnerable to computer viruses,
break-ins, and similar disruptions from unauthorized tampering. The occurrence
of any of these events could result in interruptions, delays or cessations in
service, which could have a material adverse effect on the Company's business,
results of operations and financial condition. In addition, the Company's
reputation and the GeoCities brand could be materially and adversely affected.
    
  The market in which the Company competes is characterized by rapidly
changing technology, evolving industry standards, frequent new product and
service announcements and enhancements and changing customer demands.
Accordingly, the Company's success will depend on its ability to adapt to
rapidly changing technologies and industry standards, and its ability to
continually improve the speed, performance, features, ease of use and
reliability of its server and networking system in
 
                                      13
<PAGE>
 
response to both evolving demands of the marketplace and competitive service
and product offerings. Any failure to rapidly adapt in a changing environment
would have a material adverse effect on the Company's business, results of
operations and financial condition.
 
  The Company continually strives to incorporate new technology into its Web
site for the benefit of its members, visitors and advertising and commerce
partners. Introducing new technology into the Company's systems involves
numerous technical challenges, substantial amounts of personnel resources and
often times takes many months to complete. There can be no assurance that the
Company will be successful at integrating such technology into its Web site on
a timely basis or without degrading the responsiveness and speed of its Web
site or that, once integrated, such technology will function as expected.
 
GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES
 
 GENERAL
   
  The Company is not currently subject to direct regulation by any government
agency, other than regulations applicable to businesses generally, and there
are currently few laws or regulations directly applicable to access to or
commerce on the Internet. However, due to the increasing popularity and use of
the Internet, a number of legislative and regulatory proposals are under
consideration by federal, state, local and foreign governmental organizations,
and it is possible that a number of laws or regulations may be adopted with
respect to the Internet relating to such issues as user privacy, user
screening to prevent inappropriate uses of the Internet by, for example,
minors or convicted criminals, taxation, infringement, pricing, content
regulation, quality of products and services and intellectual property
ownership and infringement. The adoption of any such laws or regulations may
decrease the growth in the use of the Internet, which could in turn decrease
the demand for the Company's community, increase the Company's cost of doing
business, or otherwise have a material adverse effect on the Company's
business, results of operations and financial condition. Moreover, the
applicability to the Internet of existing laws governing issues such as
property ownership, copyright, trademark, trade secret, obscenity, libel and
personal privacy is uncertain and developing. Any new legislation or
regulation, or application or interpretation of existing laws, could have a
material adverse effect on the Company's business, results of operations and
financial condition. For example, although it was held unconstitutional, the
Telecommunications Act of 1996 prohibited the transmission over the Internet
of certain types of information and content. Other nations, including Germany
and China, have taken actions to restrict the free flow of material on the Web
deemed to be objectionable. In addition, although substantial portions of the
Communications Decency Act (the "CDA") were held to be unconstitutional, there
can be no assurance that similar legislation will not be enacted in the
future, and it is possible that such legislation could expose the Company to
substantial liability. Legislation like the CDA could also dampen the growth
in use of the Web generally and decrease the acceptance of the Web as a
communications and commercial medium, and could, thereby, have a material
adverse effect on the Company's business, results of operations and financial
condition. It is also possible that the Company's use of "cookies" to track
demographic information and user preferences and to target advertising may
become subject to laws limiting or prohibiting their use. A "cookie" is a bit
of information keyed to a specific server, file pathway or directory location
that is stored on a user's hard drive, possibly without the user's knowledge.
A user is generally able to remove cookies. Germany, for example, has imposed
laws limiting the use of cookies, and a number of Internet commentators,
advocates and governmental bodies in the United States and other countries
have urged the passage of laws limiting or abolishing the use of cookies.
Limitations on or elimination of the Company's use of cookies could limit the
effectiveness of the Company's targeting of advertisements, which could have a
material adverse effect on the Company's business, results of operations and
financial condition. In addition, a number of legislative proposals have been
made at the federal, state and local level that would impose additional taxes
on the sale of goods and services over the Internet and certain states have
taken measures to tax Internet-related activities. Currently, Congress is
considering a number of     
 
                                      14
<PAGE>
 
   
versions of legislation which would place a moratorium of a number of years on
any new taxation of Internet commerce. There can be no assurance that any such
legislation will be adopted by Congress. Moreover, it is likely that, once
such moratorium is lifted, some type of federal and/or state taxes will be
imposed upon Internet commerce, and there can be no assurance that such
legislation or other attempts at regulating commerce over the Internet will
not substantially impair the growth of commerce on the Internet and, as a
result, adversely affect the Company's opportunity to derive financial benefit
from such activities. In addition to the foregoing areas of recent legislative
activities, several telecommunications carriers are currently seeking to have
telecommunications over the Web regulated by the Federal Communications
Commission (the "FCC") in the same manner as other telecommunications
services. For example, America's Carriers Telecommunications Association has
filed a petition with the FCC for this purpose. In addition, because the
growing popularity and use of the Web have burdened the existing
telecommunications infrastructure and many areas with high Web use have begun
to experience interruptions in phone service, local telephone carriers have
petitioned the FCC to regulate ISPs and OSPs in a manner similar to long-
distance telephone carriers and to impose access fees on the ISPs and OSPs. If
either of these petitions is granted, or the relief sought therein is
otherwise granted, the costs of communicating on the Web could increase
substantially, potentially slowing growth in use of the Web, which could in
turn decrease demand for the Company's services or increase the Company's cost
of doing business.     
 
  Due to the global nature of the Web, it is possible that, although
transmissions by the Company over the Internet originate primarily in the
State of California, the governments of other states and foreign countries
might attempt to regulate the Company's transmissions or prosecute the Company
for violations of their laws. There can be no assurance that violations of
local laws will not be alleged or charged by state or foreign governments,
that the Company might not unintentionally violate such laws or that such laws
will not be modified, or new laws enacted, in the future. Any of the foregoing
developments could have a material adverse effect on the Company's business,
results of operations and financial condition.
   
  In addition, as the Company's services are available over the Internet in
multiple states and foreign countries, such jurisdictions may claim that the
Company is required to qualify to do business as a foreign corporation in each
such state or foreign country. The Company is qualified to do business only in
California and New York, and failure by the Company to qualify as a foreign
corporation in a jurisdiction where it is required to do so could subject the
Company to taxes and penalties and could result in the inability of the
Company to enforce contracts in such jurisdictions. Any such new legislation
or regulation, the application of laws and regulations from jurisdictions
whose laws do not currently apply to the Company's business, or the
application of existing laws and regulations to the Internet and other online
services could have a material adverse effect on the Company's business,
results of operations and financial condition.     
          
  The Company's "GeoRewards" affinity program, which entitles Homesteaders to
receive GeoPoints and GeoTickets redeemable for merchandise, such as T-shirts,
books, music or other merchandise, also exposes the Company to certain
additional risks and expenses including, without limitation, those related to
compliance with consumer protection laws, loss of customer data, disputes over
redemption procedures and rules, product liability, sales taxation and
liabilities associated with any failure in the performance by participating
merchants.     
 
 FEDERAL TRADE COMMISSION INVESTIGATION
 
  In September 1997, GeoCities received a letter from the Federal Trade
Commission (the "FTC") requesting that GeoCities voluntarily produce certain
information regarding GeoCities' collection and use of personal identifying
information. GeoCities produced the requested information as well as certain
supplemental information in late 1997. In February 1998, the FTC staff sent a
draft complaint and draft consent order to GeoCities. At that time, the FTC
staff indicated that, if approved by the FTC,
 
                                      15
<PAGE>
 
an administrative suit would be brought against GeoCities alleging that it had
violated Section 5(a) of the Federal Commission Act (the "FTC Act") by
engaging in unfair and deceptive practices in connection with the Company's
collection and use of personal identifying information obtained from
individuals, including children. The FTC staff also offered to settle the
matter under the terms contained in the draft consent order.
 
  After receiving the draft complaint and draft consent order, GeoCities and
the FTC staff engaged in settlement discussions. As a result of these
discussions, on June 11, 1998, the Company and FTC staff attorneys executed an
Agreement Containing Consent Order (the "Proposed Consent Order") which is
subject to FTC approval including a period of public comment, to settle the
matter. The Proposed Consent Order resolves the FTC's allegations (which are
contained in a revised draft complaint to be filed by the FTC with the
Proposed Consent Order) that the Company: (i) disclosed to third parties
personal identifying information collected in its member application process
contrary to what had been represented to consumers by the Company; (ii)
implied that there was an affiliation between the Company and a children's
club operated by a GeoCities Community Leader such that children provided
personal identifying information to the club believing they were disclosing
the information to GeoCities and (iii) failed to disclose to consumers
(including the parents of children) how the Company would use the personal
identifying information it collected from those consumers and children. Under
the Proposed Consent Order, GeoCities would be required to: (i) cease and
desist from the allegedly deceptive practices in the future and (ii) establish
certain procedures to: (a) give adequate notice to consumers regarding
GeoCities' information collection and disclosure practices; (b) provide
consumers with the ability to have GeoCities delete their personal identifying
information from GeoCities' database; (c) more clearly identify its
affiliation (or lack thereof) with third parties which may collect information
or sponsor activities on GeoCities; and (d) obtain express parental consent
prior to collecting and using personal identifying information obtained from
children under 13 years of age. By the terms of the Proposed Consent Order,
GeoCities would not admit any of the allegations contained in the complaint,
nor would it be required to make any monetary payment to the FTC or consumers.
 
  Although the Proposed Consent Order requires that the Company take specific
actions, including those outlined above, GeoCities has been and remains
committed to protecting the privacy rights of all consumers (and, in
particular children) on the Internet. As part of its ongoing efforts to
enhance the protection of the privacy of its members, the Company has
consulted and worked with industry self-regulation groups and has implemented
or intends to implement programs designed to enhance the protection of the
privacy of its members, including children. Such programs include: (i)
publishing a comprehensive, multi-screen, privacy statement that is accessible
from many places on the Company's Web site, including the GeoCities home page
and new member application form; (ii) revamping the new member application
form to make the questions clearer to consumers; (iii) enhancing its training
program for Community Leaders; (iv) suspending certain e-mail marketing
programs of an affiliate and confirming that the affiliate had never sent e-
mails to individuals based on the representation included in the application
form; (v) altering its rules to expressly forbid third parties from collecting
information in connection with promotions for any purpose other than to
fulfill the promotion; (vi) instructing companies that received information
from the Company regarding children under 13 to cease use of such information;
(vii) making changes to the content that appears on the Company's Web site,
such as warnings to children not to give out personal information, and
removing inappropriate advertising and promotions from GeoCities' children and
family-oriented "EnchantedForest" neighborhood and (viii) requiring that
individuals under 13 involve their parents in the process of applying for a
free membership in GeoCities. To confirm the adequacy of its disclosure
practices in the area of information collection and use, the Company submitted
its privacy statement to TRUSTe, an industry self-regulation group. TRUSTe has
certified such statement as an accurate representation to consumers of
GeoCities' information collection practices.
 
                                      16
<PAGE>
 
   
  The Proposed Consent Order has been approved by the Director of Consumer
Protection for the FTC, but remains subject to preliminary and final approval
by the FTC after a period of public comment. There can be no assurance that
the Proposed Consent Offer ultimately will be approved by the FTC. If the
Proposed Consent Order is not approved by the FTC and the FTC ultimately
decides to file suit, the Company intends to vigorously defend itself against
the FTC's allegations. If the FTC files suit, there can be no assurance that
the FTC will not make additional allegations against the Company or seek more
extensive relief than the relief sought by the Proposed Consent Order, or that
any subsequent settlement, or other relief ultimately obtained by the FTC will
not exceed the relief contained in the Proposed Consent Order. If more
extensive relief is obtained by the FTC, there can be no assurance that it
will not have a material adverse effect on the Company's business, results of
operations or financial condition.     
   
 LIABILITY FOR INFORMATION RETRIEVED FROM THE WEB     
   
  Because materials may be downloaded by members and other users of the
Company's Web site and subsequently distributed to others, there is a
potential that claims will be made against the Company for defamation,
negligence, copyright or trademark infringement, personal injury or other
theories based on the nature, content, publication and distribution of such
materials. Such claims have been brought, and sometimes successfully pressed,
against OSPs for example in the past. The Company has received inquiries on a
regular basis from third parties regarding such matters, all of which have
been resolved to date without any payments or other material adverse effect on
the Company. In addition, the increased attention focused upon liability
issues as a result of these lawsuits and legislative proposals could impact
the overall growth of Internet use. The Company could also be exposed to
liability with respect to the offering of third-party content that may be
accessible through the Company's Web site, or through content and materials
that may be posted by members on their personal Web sites or chat rooms, or
bulletin boards offered by the Company. Such claims might include, among
others, that by directly or indirectly hosting the personal Web sites of third
parties, the Company is liable for copyright or trademark infringement or
other wrongful actions by such third parties through such Web sites. It is
also possible that if any third-party content information provided on the
Company's Web site contains errors, third parties could make claims against
the Company for losses incurred in reliance on such information. The Company
also offers e-mail services, which expose the Company to potential risk, such
as liabilities or claims resulting from unsolicited e-mail (spamming), lost or
misdirected messages, illegal or fraudulent use of e-mail or interruptions or
delays in e-mail service. Even to the extent that such claims do not result in
liability to the Company, the Company could incur significant costs in
investigating and defending against such claims. The imposition on the Company
of potential liability for information carried on or disseminated through its
systems could require the Company to implement measures to reduce its exposure
to such liability, which may require the expenditure of substantial resources
and limit the attractiveness of the Company's services to members and users.
The Company also enters into agreements with commerce partners and sponsors
under which the Company is in general entitled to receive a share of any
revenue from the purchase of goods and services through direct links from the
Company's Web site. Such arrangements may expose the Company to additional
legal risks and uncertainties, including potential liabilities to consumers of
such products and services by virtue of the Company's involvement in providing
access to such products or services, even if the Company does not itself
provide such products or services. While the Company's agreements with these
parties often provide that the Company will be indemnified against such
liabilities, there can be no assurance that such indemnification, if
available, will be adequate. Although the Company carries general liability
insurance, the Company's insurance may not cover all potential claims to which
it is exposed or may not be adequate to indemnify the Company for all
liability that may be imposed. Any imposition of liability that is not covered
by insurance or is in excess of insurance coverage could have a material
adverse effect on the Company's business, results of operations and financial
condition. In addition, the increased attention focused upon liability issues
as a result of these lawsuits and legislative proposals could impact the
overall growth of Internet use.     
 
                                      17

RISKS ASSOCIATED WITH BRAND DEVELOPMENT
 
  The Company believes that establishing and maintaining the GeoCities brand
is a critical aspect of its efforts to attract and expand its member base, Web
traffic and advertising and commerce relationships, and that the importance of
brand recognition will increase due to the growing number of Internet sites
and the low barriers to entry. In order to attract and retain members,
Internet users, advertisers and commerce partners, and to promote and maintain
the GeoCities brand in response to competitive pressures, the Company intends
to increase substantially its financial commitment to creating and maintaining
distinct brand loyalty among these groups, including through traditional media
advertising campaigns in print, radio, billboards and television. Promotion
and enhancement of the GeoCities brand will also depend, in part, on the
Company's success in providing a high-quality community experience, which
success cannot be ensured. If the Company does not generate a corresponding
increase in revenue as a result of its branding efforts or otherwise fails to
promote its brand successfully, or if the Company incurs excessive expenses in
an attempt to promote and maintain its brand, the Company's business, results
of operations and financial condition, will be materially and adversely
affected. If members, visitors to the GeoCities Web site, advertisers or
businesses do not perceive the Company's existing services to be of high
quality, or if the Company introduces new services or enters into new business
ventures that are not favorably received by such parties, the value of the
Company's brand could be diluted, thereby decreasing the attractiveness of its
Web site to such parties.
 
SECURITY RISKS
   
  The Company has experienced attempts by experienced programmers or "hackers"
to penetrate the Company's network security, some of which have succeeded, and
expects these attempts to continue to occur from time to time. To date, none
of this activity has had a material adverse effect on the Company's business,
results of operations or financial condition. A party who is able to penetrate
the Company's network security could misappropriate proprietary information or
cause interruptions in the Company's Web site. In addition, in offering
certain payment services through its GeoShops program, the Company could
become increasingly reliant on encryption and authentication technology
licensed from third parties to provide the security and authentication
necessary to effect secure transmission of confidential information, such as
customer credit card numbers. Advances in computer capabilities, discoveries
in the field of cryptography and other discoveries, events, or developments
could lead to a compromise or breach of the algorithms that the Company's
licensed encryption and authentication technology uses to protect such
confidential information. If such a compromise or breach of the Company's
licensed encryption authentication technology occurs, it could have a material
adverse effect on the Company's business, results of operations and financial
condition. The Company may be required to expend significant capital and
resources to protect against the threat of such security, encryption and
authentication technology breaches or to alleviate problems caused by such
breaches. Concerns over the security of Internet transactions and the privacy
of users may also inhibit the growth of the Internet generally, particularly
as a means of conducting commercial transactions. Security breaches or the
inadvertent transmission of computer viruses could expose the Company to a
risk of loss or litigation and possible liability. There can be no assurance
that contractual provisions attempting to limit the Company's liability in
such areas will be successful or enforceable, or that other parties will
accept such contractual provisions as part of the Company's agreements which
could have a material adverse effect on the Company's business, results of
operations and financial condition.     
       
RELIANCE ON INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
  The Company regards its technology as proprietary and attempts to protect it
by relying on trademark, service mark, copyright and trade secret laws and
restrictions on disclosure and transferring title and other methods. The
Company currently has no patents or patents pending and does not anticipate
that patents will become a significant part of the Company's intellectual
property in the foreseeable future. The Company also generally enters into
confidentiality or license agreements

with its employees and consultants, and generally controls access to and
distribution of its documentation and other proprietary information. Despite
these precautions, it may be possible for a third party to copy or otherwise
obtain and use the Company's proprietary information without authorization or
to develop similar technology independently. The Company pursues the
registration of its service marks in the United States and internationally,
and has applied for and obtained the registration in the United States for a
number of its service marks, including "GeoCities". Effective trademark,
service mark, copyright and trade secret protection may not be available in
every country in which the Company's services are distributed or made
available through the Internet, and policing unauthorized use of the Company's
proprietary information is difficult.     
 
  Legal standards relating to the validity, enforceability and scope of
protection of certain proprietary rights in Internet-related businesses are
uncertain and still evolving, and no assurance can be given as to the future
viability or value of any proprietary rights of the Company or other companies
within this market. There can be no assurance that the steps taken by the
Company will prevent misappropriation or infringement of its proprietary
information. Any such infringement or misappropriation, should it occur, could
have a material adverse effect on the Company's business, results of
operations and financial condition. In addition, litigation may be necessary
in the future to enforce the Company's intellectual property rights, to
protect the Company's trade secrets or to determine the validity and scope of
the proprietary rights of others. Such litigation might result in substantial
costs and diversion of resources and management attention and could have a
material adverse effect on the Company's business, results of operations and
financial condition. Furthermore, there can be no assurance that the Company's
business activities will not infringe upon the proprietary rights of others,
or that other parties will not assert infringement claims against the Company.
From time to time, the Company has been, and expects to continue to be,
subject to claims in the ordinary course of its business including claims of
alleged infringement of the trademarks, service marks and other intellectual
property rights of third parties by the Company and the content generated by
its members. Although such claims have not resulted in any significant
litigation or had a material adverse effect on the Company's business to date,
such claims and any resultant litigation, should it occur, might subject the
Company to significant liability for damages and might result in invalidation
of the Company's proprietary rights and even if not meritorious, could be time
consuming and expensive to defend and could result in the diversion of
management time and attention, any of which might have a material adverse
effect on the Company's business, results of operations and financial
condition.
   
  The Company currently licenses from third parties certain technologies
incorporated into the Company's Web site. As the Company continues to
introduce new services that incorporate new technologies, it may be required
to license additional technology from others. There can be no assurance that
these third-party technology licenses will continue to be available to the
Company on commercially reasonable terms, if at all. The inability of the
Company to obtain any of these technology licenses could result in delays or
reductions in the introduction of new services or could adversely affect the
performance of its existing services until equivalent technology could be
identified, licensed and integrated. See "Business--Intellectual Property and
Proprietary Rights".     
   
DEPENDENCE ON CONTINUED GROWTH IN THE USE OF THE INTERNET; DEPENDENCE ON WEB
INFRASTRUCTURE     
   
  The Company's future success is substantially dependent upon continued
growth in the use of the Internet and the Web in order to support the sale of
advertising on the Company's Web site and in the acceptance and volume of
commerce transactions on the Internet. There can be no assurance that the
number of Internet users will continue to grow or that commerce over the
Internet will become more widespread. As is typical in the case of a new and
rapidly evolving industry, demand and market acceptance for recently
introduced services are subject to a high level of uncertainty. The Internet
may not prove to be a viable commercial marketplace for a number of reasons,
including lack of acceptable security technologies, lack of access and ease of
use, congestion of traffic, inconsistent quality of service and lack of
availability of cost-effective, high-speed service, potentially inadequate
    
                                      19

development of the necessary infrastructure, excessive governmental
regulation, uncertainty regarding intellectual property ownership or timely
development and commercialization of performance improvements, including high-
speed modems.     
 
  The success of the GeoCities Web site will depend in large part upon the
continued development of a Web infrastructure, such as a reliable network
backbone with the necessary speed, data capacity and security, and timely
development of complementary products such as high speed modems for providing
reliable Web access and services. Because global commerce and online exchange
of information on the Web and other similar open wide area networks are new
and evolving, it is difficult to predict with any assurance whether the Web
will support increasing use or will prove to be a viable commercial
marketplace. The Web has experienced, and is expected to continue to
experience, significant growth in the number of users and the amount of
content. To the extent that the Web continues to experience increased numbers
of users, frequency of use or increased bandwidth requirements of users, there
can be no assurance that the Web infrastructure will continue to be able to
support the demands placed on it by this continued growth or that the
performance or reliability of the Web will not be adversely affected by this
continued growth. In addition, the Web could lose its viability or
effectiveness due to delays and the development or adoption of new standards
and protocols to handle increased levels of activities or due to increased
government regulation. There can be no assurance that the infrastructure or
complementary products or services necessary to make the Web a viable
commercial marketplace will be developed, or, if they are developed, that the
Web will achieve broad acceptance. If the necessary infrastructure standards,
protocols or complementary products, services or facilities are not developed,
or if the Web does not become a viable commercial marketplace, the Company's
business, results of operations and financial condition will be materially and
adversely affected. Even if such infrastructure, standards or protocols or
complementary products, services or facilities are developed and the Web
becomes a viable commercial marketplace, there can be no assurance that the
Company will not be required to incur substantial expenditures in order to
adapt its services to changing Web technologies, which could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS AND EXPANSION
 
  A part of the Company's strategy is to develop the GeoCities community model
in international markets. There can be no assurance that the Internet, the Web
or the Company's community model will become widely accepted in any
international markets. The Company has developed and operates with SOFTBANK
Corporation of Japan ("SOFTBANK"), GeoCities Japan Corporation ("GeoCities
Japan"), a joint venture that is 40% owned by GeoCities. The Company has not
generated a material amount of revenue from its ownership interest in
GeoCities Japan to date. The Company has only limited experience in developing
this localized version of its community model and will be relying heavily on
the efforts and abilities of SOFTBANK in such venture. In addition, the
Company expects that the success of any additional foreign operations it
initiates in the future will also be substantially dependent upon local
partners. If revenues from international ventures are not adequate to cover
the investments in such activities, the Company's business, results of
operations and financial condition could be materially and adversely affected.
The Company may experience difficulty in managing international operations as
a result of difficulty in locating an effective foreign partner, competition,
technical problems, distance and language and cultural differences, and there
can be no assurance that the Company or its international partners will be
able to successfully market and operate the Company's community model in
foreign markets. The Company also believes that in light of substantial
anticipated competition, it will be necessary to move quickly into
international markets in order to effectively obtain market share, and there
can be no assurance that the Company will be able to do so. There are certain
risks inherent in doing business on an international level, such as unexpected
changes in regulatory requirements, trade barriers, difficulties in staffing
and managing foreign operations, fluctuations in currency exchange rates,
longer payment cycles in general, problems in collecting accounts receivable,
difficulty in enforcing contracts, political and economic instability,
seasonal reductions in business activity in certain other parts
 
                                      20
<PAGE>
 
of the world and potentially adverse tax consequences. There can be no
assurance that one or more of such factors will not have a material adverse
effect on the Company's future international operations and, consequently, on
the Company's business, results of operations and financial condition.
 
CONTROL BY DIRECTORS, EXECUTIVE OFFICERS, CMG@VENTURES AND SOFTBANK
   
  Upon completion of the offering, CMG@Ventures and SOFTBANK, and their
respective affiliates, will, in the aggregate, beneficially own approximately
62.8% of the outstanding Common Stock. In addition, upon completion of the
offering, the directors, executive officers and principal stockholders of the
Company and their respective affiliates will, in the aggregate, beneficially
own approximately 73.2% of the outstanding Common Stock. As a result, these
stockholders will possess significant influence over the Company, giving them
the ability, among other things, to elect a majority of the Company's Board of
Directors and approve significant corporate transactions. Such share ownership
and control may also have the effect of delaying or preventing a change in
control of the Company, impeding a merger, consolidation, takeover or other
business combination involving the Company or discourage a potential acquiror
from making a tender offer or otherwise attempting to obtain control of the
Company which could have a material adverse effect on the market price of the
Company's Common Stock.     
 
FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FINANCING
 
  The Company currently anticipates that the net proceeds of the offering,
together with its existing line of credit and available funds will be
sufficient to meet its anticipated needs for working capital and capital
expenditures for at least the next 12 months. The Company may need to raise
additional funds in the future in order to fund more aggressive brand
promotions and more rapid expansion, to develop newer or enhanced services, to
respond to competitive pressures or to acquire complementary businesses,
technologies or services. If additional funds are raised through the issuance
of equity or convertible debt securities, the percentage ownership of the
stockholders of the Company will be reduced, stockholders may experience
additional dilution and such securities may have rights, preferences or
privileges senior to those of the rights of the Company's Common Stock. There
can be no assurance that additional financing will be available on terms
favorable to the Company, or at all. If adequate funds are not available or
not available on acceptable terms, the Company may not be able to fund its
expansion, promote its brand names as the Company desires, take advantage of
unanticipated acquisition opportunities, develop or enhance services or
respond to competitive pressures. Any such inability could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
RISKS ASSOCIATED WITH POTENTIAL ACQUISITIONS
 
  As part of its business strategy, the Company expects to review acquisition
prospects that would complement its existing business, augment the
distribution of its community or enhance its technological capabilities.
Although the Company currently has no agreements with respect to any material
acquisitions, the Company may make acquisitions of complementary businesses,
products or technologies in the future. However, there can be no assurance
that the Company will be able to locate suitable acquisition opportunities.
Future acquisitions by the Company could result in potentially dilutive
issuances of equity securities, large and immediate write-offs, the incurrence
of debt and contingent liabilities or amortization expenses related to
goodwill and other intangible assets, any of which could materially and
adversely affect the Company's results of operations. Furthermore,
acquisitions entail numerous risks and uncertainties, including difficulties
in the assimilation of operations, personnel, technologies, products and the
information systems of the acquired companies, diversion of management's
attention from other business concerns, risks of entering geographic and
business markets in which the Company has no or limited prior experience and
potential loss of key employees of acquired organizations. The Company has not
made any material acquisitions in the past. No assurance can be given as to
the ability of the Company to successfully integrate any businesses, products,
technologies or personnel that might be acquired in the future, and the
failure of the Company to do so could have a material adverse effect on the
Company's business, results of operations and financial condition.

YEAR 2000 COMPLIANCE
   
  The Company is aware of the issues associated with the programming code in
existing computer systems as the year 2000 approaches. The "year 2000 problem"
is pervasive and complex as virtually every computer operation will be
affected in some way by the rollover of the two digit year value to 00. The
issue is whether computer systems will properly recognize date-sensitive
information when the year changes to 2000. Systems that do not properly
recognize such information could generate erroneous data or fail. The Company
is in the process of working with its software vendors to ensure that the
software that the Company has licensed from third parties will operate
properly in the year 2000 and beyond. In addition, the Company is working with
its external suppliers and service providers to ensure that they and their
systems will be able to support the Company's needs and, where necessary,
interoperate with the Company's server and networking hardware and software
infrastructure in preparation for the year 2000. Management does not
anticipate that the Company will incur significant operating expenses or be
required to invest heavily in computer systems improvements to be year 2000
compliant. However, significant uncertainty exists concerning the potential
costs and effects associated with any year 2000 compliance. Any year 2000
compliance problems of either the Company, its customers or vendors could have
a material adverse effect on the Company's business, results of operations and
financial condition.     
       
   
PUBLICITY     
   
  In March and April 1998 interviews with the New York Times, certain members
of the Company's management either disclosed or confirmed certain prospective
financial information regarding the Company. Such information was reported in
a July 13, 1998 article in the New York Times regarding the Company.
Specifically, the New York Times article included statements from a March
interview of the then President and Chief Executive Officer that the Company
was hoping to achieve revenues of between $20 million and $25 million in 1998,
and from an April interview of the Chief Financial Officer that the Company
expected to "break even" in 1999. These statements were made prior to the time
the Company began preparing for the offering and were not made in anticipation
of the offering. These statements were not intended to be relied upon by
potential investors in making an investment decision to purchase the Common
Stock offered hereby. The Company disclaims all such statements for purposes
of the offering and prospective investors should not rely on such statements
or any other information not contained in this Prospectus in making any
investment decision to purchase the Common Stock offered hereby. Revenue and
profitability forecasts of any company, especially in the rapidly evolving
Internet market, are forward-looking statements that involve numerous risks
and uncertainties. The Company's actual results could differ materially from
those stated in such forward-looking statements as a result of numerous
factors, including those set forth in these "Risk Factors" and elsewhere in
this Prospectus.     
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
   
  Sales of significant amounts of Common Stock in the public market after the
offering or the perception that such sales will occur could materially and
adversely affect the market price of the Common Stock or the future ability of
the Company to raise capital through an offering of its equity securities. Of
the 30,661,000 shares of Common Stock to be outstanding upon the closing of
the offering (assuming no exercise of the Underwriters' over-allotment option
and based on the number of shares outstanding as of June 30, 1998), the
4,750,000 shares offered hereby will be eligible for immediate sale in the
public market without restriction, unless the shares are purchased by
"affiliates" of the Company within the meaning of Rule 144 promulgated under
the Securities Act of 1933, as amended (the "Securities Act"). The 15,840
shares of Common Stock to be issued to the Community Leaders and Liaisons
under the 1998 Stock Incentive Plan will also be eligible for immediate sale
in the public market without restriction, subject to the filing of the Form S-
8 registration statement with respect thereto as of the date of this
Prospectus. The remaining 25,895,000 shares of Common Stock held by existing
stockholders upon the     
 
                                      22
<PAGE>
 
   
closing of the offering (based on the number of shares of Common Stock
outstanding as of June 30, 1998, and giving effect to the Preferred Stock
Conversion) will be "restricted securities" as that term is defined in 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. The Company's directors and officers, and substantially all of its other
stockholders and holders of options to purchase Common Stock, have agreed that
they will not sell, directly or indirectly, any Common Stock without the prior
consent of Goldman, Sachs & Co. for a period of 180 days from the date of this
Prospectus. Subject to the provisions of Rules 144, 144(k) and 701, 25,895,000
shares will be eligible for sale 180 days after the date of this Prospectus
upon the expiration of such lock-up agreements. However, one affiliate of the
Company who is subject to a lock-up agreement and the volume limitations of
Rule 144 will be permitted to sell up to $1.0 million of Common Stock
commencing 91 days after the date of this Prospectus. Any shares of Common
Stock issued pursuant to the technology purchase agreement will be restricted
securities and will also be subject to a 180 day lock-up agreement. In
addition, as of June 30, 1998, there were outstanding options to purchase up
to 6,531,000 shares of Common Stock which will be eligible for sale in the
public market following the offering from time to time subject to becoming
exercisable and the expiration of any lock-up agreements applicable thereto.
There is also a warrant outstanding to purchase up to 20,304 shares of Common
Stock which will be eligible for sale in the public market following the
offering, subject to being exercised and the expiration of the 180-day lock-up
agreement applicable thereto. In addition, subject to the lock-up agreements,
certain stockholders, holding an aggregate of 26,160,128 shares of Common
Stock (including shares issuable upon the exercise of certain options to
purchase Common Stock), have the right, subject to certain conditions, to
include their shares in future registration statements relating to the
Company's securities, and certain stockholders holding an aggregate of
22,230,128 shares of Common Stock have the right, subject to certain
conditions, to cause the Company to register their shares of Common Stock. In
addition, in the event that the Company proposes to register any shares of
Common Stock under the Securities Act to the public in a firm commitment
underwritten public offering, David Bohnett and John Rezner, as well as any
other officer or director designated by the Company's Board of Directors by
unanimous vote, shall be entitled to piggyback registration rights if such
persons who choose to include their shares in such registration shall continue
to serve the Company as an officer or director on the effective date of such
registration statement.     
   
  The Company intends to file, as of the date of this Prospectus, Form S-8
registration statements under the Securities Act to register all shares of
Common Stock issuable under certain individual stock option agreements and the
1998 Stock Incentive Plan, the shares of Common Stock that will be issued to
the Community Leaders and Liaisons thereunder immediately following the
execution of the Underwriting Agreement and shares of Common Stock issuable
under the Purchase Plan. Such registration statements are expected to become
effective immediately upon filing, and shares covered by those registration
statements will thereupon be eligible for sale in the public markets, subject
to any lock-up agreements applicable thereto and Rule 144 limitations
applicable to affiliates. See "Management--Employee Benefit Plans",
"Description of Capital Stock--Registration Rights", "Shares Eligible for
Future Sale" and "Underwriting".     
 
NO PRIOR PUBLIC MARKET FOR COMMON STOCK; POSSIBLE VOLATILITY OF STOCK PRICE
 
  Prior to the offering, there has been no public market for the Common Stock.
Accordingly, there can be no assurance that an active trading market for the
Common Stock will develop or be sustained following the closing of the
offering or that the market price of the Common Stock will not decline below
the initial public offering price. The initial public offering price, which
may bear no relationship to the price at which the Common Stock will trade
upon completion of the offering, will be determined by negotiations between
the Company and the representatives of the Underwriters based upon factors
that may not be indicative of future market performance. See "Underwriting".
 
  The trading price of the Company's Common Stock could be subject to wide
fluctuations in response to variations in the Company's quarterly results of
operations, the gain or loss of significant
 
                                      23
<PAGE>
 
advertisers, changes in earnings estimates by analysts, announcements of
technological innovations or new solutions by the Company or its competitors,
general conditions in the technology and Internet sectors and in Internet-
related industries, other matters discussed elsewhere in this section of the
Prospectus and other events or factors, many of which are beyond the Company's
control. In addition, the stock market in general and the technology and
Internet sectors in particular have recently experienced extreme price and
volume fluctuations which have affected the market price for many companies in
industries similar or related to that of the Company and which have been
unrelated to the operating performance of these companies. These market
fluctuations, as well as general economic, political and market conditions,
may have a material adverse effect on the market price of the Company's Common
Stock. In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted against such companies. Such litigation, if instituted, and
irrespective of the outcome of such litigation, could result in substantial
costs and a diversion of management's attention and resources and have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
BROAD DISCRETION IN USE OF PROCEEDS
 
  The net proceeds of the offering will be added to the Company's working
capital. As of the date of this Prospectus, the Company cannot specify with
certainty the particular uses for the net proceeds to be received upon
completion of the offering. Accordingly, the Company's management will have
broad discretion in the application of the net proceeds. The failure of
management to apply such funds effectively could have a material adverse
effect on the Company's business, results of operations and financial
condition. See "Use of Proceeds".
   
ANTI-TAKEOVER EFFECTS OF CERTAIN CHARTER, BYLAWS AND DELAWARE LAW PROVISIONS;
POSSIBLE ISSUANCE OF PREFERRED STOCK; PROVISIONS OF 1998 STOCK INCENTIVE PLAN
    
   
  Following the closing of the offering, the Company's Board of Directors will
have the authority to issue up to 5,000,000 shares of Preferred Stock without
any further vote or action by the stockholders, and to determine the price,
rights, preferences, privileges and restrictions, including voting rights, of
such shares. Since the Preferred Stock could be issued with voting,
liquidation, dividend and other rights superior to those of the Common Stock,
the rights of the holders of Common Stock would be subject to, and may be
adversely affected by, the rights of the holders of any such Preferred Stock.
The issuance of Preferred Stock could have the effect of making it more
difficult for a third party to acquire a majority of the outstanding voting
stock of the Company. Further, certain provisions of the Company's Certificate
of Incorporation and Bylaws and of Delaware law could have the effect of
delaying or preventing a change in control of the Company. In addition,
certain provisions of the Company's 1998 Stock Incentive Plan which become
operative upon a hostile takeover, such as those involving acceleration of
vesting and required cash distributions upon surrender of options, could have
the effect of delaying, deferring or preventing a tender offer or takeover
attempt that might result in a premium over the market price for the Company's
Common Stock. See "Description of Capital Stock--Anti-Takeover Effects of
Certain Provisions of Delaware Law and the Company's Certificate of
Incorporation and Bylaws" and "Management--Employee Benefit Plans".     
   
BENEFITS OF THE OFFERING TO EXISTING STOCKHOLDERS     
   
  The existing stockholders of the Company will recognize significant benefits
from the offering. These benefits include the creation of a public market for
the Company's Common Stock which will afford existing stockholders the ability
to liquidate their investments, subject, in certain cases, to volume
limitations and other limitations and restrictions upon the sale of the Common
Stock, including any lock-up agreements applicable thereto. As of June 30,
1998, existing stockholders held 25,895,000 shares of outstanding Common Stock
(on an as-converted basis to give effect to the Preferred Stock Conversion)
which shares were originally purchased from the Company at prices ranging from
$0.01     
 
                                      24
<PAGE>
 
   
to $7.43 per share, with an aggregate consideration paid to the Company of
approximately $40,672,000. Based on an assumed initial public offering price
of $13.00 per share, after the offering (assuming no exercise of the
Underwriters' over-allotment option) the aggregate value of the outstanding
shares owned by the Company's existing stockholders will be approximately
$336,635,000 ($39,525,000 of which is held by current management), reflecting
unrealized gains of approximately $295,963,000 over the aggregate
consideration paid to the Company for such shares (assuming that such shares
continue to be held by the original purchasers thereof). Further, as of June
30, 1998, there were 6,531,000 shares of Common Stock issuable upon exercise
of outstanding options at a weighted average exercise price of $1.97. Such
options have an aggregate potential realizable gain of approximately
$72,037,000 following the offering, based on an assumed initial public
offering price of $13.00 per share. Accordingly, after the offering, existing
stockholders and optionholders will have substantial unrealized gains on their
shares and options. See "Shares Eligible For Future Sale", "Dilution" and
"Principal Stockholders".     
 
DILUTION; ABSENCE OF DIVIDENDS
   
  Investors purchasing shares of Common Stock in the offering will incur
immediate and substantial dilution of $10.47 per share in net tangible book
value per share of the Common Stock from the initial public offering price. To
the extent outstanding options to purchase Common Stock are exercised, there
will be further dilution. In addition, the Company does not anticipate paying
any cash dividends in the foreseeable future. See "Dividend Policy" and
"Dilution".

                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 4,750,000 shares of
Common Stock offered hereby are estimated to be approximately $56,377,000
million ($64,992,000 million if the Underwriters' over-allotment option is
exercised in full) after deducting the underwriting discount and estimated
offering expenses payable by the Company and assuming an initial public
offering price of $13.00 per share. The primary purposes of the offering are
to create a public market for the Common Stock, to facilitate the Company's
future access to public equity markets and to obtain additional working
capital.     
 
  The Company intends to use the net proceeds of the offering for investments
in the GeoCities community site, including enhancements to the Company's
server and networking infrastructure and the functionality of its Web site,
and general corporate purposes, including working capital, expansion of its
sales and marketing capabilities and brand-name promotions. As of the date of
this Prospectus, the Company cannot specify with certainty the particular uses
for the net proceeds to be received upon completion of the offering.
Accordingly, the Company's management will have broad discretion in the
application of the net proceeds.
 
  Pending such uses, the net proceeds will be invested in interest-bearing
investment-grade instruments, certificates of deposit or direct or guaranteed
obligations of the United States.
 
                                DIVIDEND POLICY
 
  The Company has not declared or paid any cash dividends on its capital stock
since inception and does not expect to pay any cash dividends for the
foreseeable future. The Company currently intends to retain future earnings,
if any, to finance the expansion of its business. The Company's line of credit
arrangement prohibits the payment of dividends by the Company without the
lender's prior consent.

                                   DILUTION
   
  The pro forma net tangible book value of the Company's Common Stock as of
June 30, 1998, was $21.3 million, or $0.82 per share of Common Stock, after
giving effect to the Preferred Stock Conversion. Pro forma net tangible book
value per share is equal to the amount of the Company's total tangible assets
less total liabilities, divided by the number of shares of Common Stock
outstanding as of June 30, 1998. Assuming the sale by the Company of 4,750,000
shares of Common Stock offered hereby at an assumed initial public offering
price of $13.00 per share and the application of the estimated net proceeds
therefrom, the pro forma net tangible book value of the Company as of June 30,
1998, would have been $77.7 million, or $2.53 per share of Common Stock. This
represents an immediate increase in pro forma net tangible book value of $1.71
per share to existing stockholders and an immediate dilution in pro forma net
tangible book value of $10.47 per share to new investors. The following table
illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Financial
Statements and the related Notes thereto included elsewhere in this
Prospectus. This discussion contains forward-looking statements that involve
risks and uncertainties. The Company's actual results may differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including, but not limited to, those set forth under "Risk
Factors" and elsewhere in this Prospectus.
 
OVERVIEW
   
  GeoCities offers the world's largest and one of the fastest growing
communities of personal Web sites on the Internet. GeoCities pioneered the
first large-scale, Web-based community for Internet users to express
themselves, share ideas, interests and expertise, and publish content
accessible to other users with common interests. The mainstay of the Company's
community are its "Homesteaders," Internet users who create their own personal
Web sites or "Homesteads" in themed "neighborhoods" on the GeoCities Web site.
These neighborhoods provide a context for Web users to publish content, to
share experiences and ideas with other users and to access a centralized and
easy-to-navigate destination for user-published content.     
   
  Founded in December 1994 as Beverly Hills Internet, the Company first
launched an online community of six neighborhoods in January 1995. From
January 1995 through early 1996, the Company's operating activities related
primarily to developing software and hardware infrastructure for the Company's
Web site, recruiting personnel, raising capital and developing programs to
attract Homesteaders. During this period, the Company's revenues were derived
from commercial Web site set-up and maintenance operations which were de-
emphasized in early 1996. The Company changed its name to GeoCities in early
1996, and, for the remainder of 1996 and through 1997, shifted its focus
toward building its Homesteader membership base, broadening the functionality
of the Company's Web site, developing a broader range of neighborhoods and, to
a lesser extent, selling advertising on its Web site. The Company began
focusing on generating advertising revenues in 1996 as a result of the
maturing advertising market on the Internet. Moreover, the Company determined
that it was generating sufficient traffic to support the efforts of a
dedicated advertising sales team. The Company reached one million Homesteads
in October 1997 and over 2.1 million Homesteads in July 1998. From the end of
1997 through May 1998, the Company hired substantially all of its senior
management team and began to focus more strongly on building its revenue base.
    
   
  To date, the Company's revenues have been derived principally from the sale
of advertisements. Advertising revenues constituted 90.2% of net revenues for
the six months ended June 30, 1998 and 90.6% of net revenues for 1997. The
Company sells banner advertisements, event sponsorships and premium site
locations within the Company's Web site. The Company also receives advertising
revenues from select premier commerce partners in return for preferred banner
advertising locations on, and integration into, the Company's Web site. The
Company has also recently begun receiving advertising revenues from third-
party content providers who pay the Company for displaying their content on
the Company's Web site. Currently, the duration of the Company's banner
advertising arrangements averages between one to two months. Advertising rates
are dependent on whether the impressions are for general rotation throughout
the Company's Web site or for targeted audiences and properties within
specific areas of the GeoCities site. All advertising revenues are recognized
ratably in the period in which the advertisement is displayed, provided that
no significant Company obligations remain and collection of the resulting
receivable is probable. Company obligations typically include guarantees of a
minimum number of "impressions" or times that an advertisement appears in page
views downloaded by users. Payments received from advertisers prior to
displaying their advertisements on the site are recorded as deferred revenues
and are recognized as revenue ratably when the advertisement is displayed.
    
                                      30
<PAGE>
 
   
  In addition to advertising revenues, the Company derives other revenues
primarily from its GeoPlus program, and, to a lesser extent, from its GeoShops
program and revenue-sharing arrangements with its premier commerce partners.
The Company's GeoPlus program offers premium services for a monthly fee,
providing Homesteaders additional disk space and enhanced publishing tools for
their Web pages. In March 1998, the Company introduced the GeoShops program, a
commerce service that, for a monthly fee, allows Homesteaders to sell products
and services on their personal Web sites, and, for an additional fee, provides
Homesteaders with transaction authorization and processing capabilities. The
Company's agreements with its premier commerce partners generally provide the
Company with a share of any sales resulting from direct links from the
Company's Web site, subject to certain minimum sales levels. Revenues from the
GeoPlus and GeoShops programs are recognized in the month that the service is
provided. Revenues from the Company's share of the proceeds from its premier
commerce partners' sales are recognized by the Company upon notification from
its premier commerce partners of sales attributable to the Company's Web site.
To date, revenues from such revenue-sharing arrangements have not been
material.     
   
  The Company has incurred significant losses since its inception, and as of
June 30, 1998, had an accumulated deficit of approximately $19.7 million.
Also, in connection with the grant of certain stock options to employees
during 1997 and the six months ended June 30, 1998, the Company recorded
unearned deferred compensation of approximately $7.4 million through June 30,
1998, representing the difference between the deemed value of the Company's
Common Stock for accounting purposes and the exercise price of such options at
the date of grant. Such amount, net of amortization, is presented as a
reduction of stockholders' equity and amortized over the vesting period of the
applicable options. As a result, the Company currently expects to amortize the
following amounts of deferred compensation annually: 1998--$1.1 million;
1999--$1.6 million; 2000--$1.8 million; 2001--$1.8 million; 2002--$766,000;
2003--$265,000 and 2004--$90,000. Amortization of deferred compensation was
$290,000 and $24,000 for the six months ended June 30, 1998, and for 1997,
respectively.     
   
  The Company and the FTC staff attorneys executed the Proposed Consent Order
in June 1998, in connection with the FTC's investigation into certain past
business practices of the Company. The Proposed Consent Order has been
approved by the Director of Consumer Protection for the FTC, but is subject to
final FTC approval after a period of public comment. There can be no assurance
that the Proposed Consent Offer ultimately will be approved. Based on the
scope of the Proposed Consent Order, the Company does not believe that its
compliance with the Order will have a material adverse effect on the Company's
business, results of operations or financial condition.

SIX MONTHS ENDED JUNE 30, 1998 AND 1997     
 
  NET REVENUES
   
  Net revenues increased 240% to $5.5 million for the six months ended June
30, 1998, from $1.6 million for the six months ended June 30, 1997. The
increase in net revenues was due primarily to an increase in the number of
advertisers, the addition of the Company's premier commerce partners, the
increase in the Company's Web site traffic and, to a lesser extent, expansion
in GeoPlus memberships and the addition of third-party content providers which
pay the Company for carrying their content within the GeoCities community.
Advertising revenues accounted for approximately 90.2% and 92.2% of net
revenues for the six months ended June 30, 1998 and 1997, respectively. The
Company's four largest customers accounted for approximately 28% and 30% of
net revenues in the six months ended June 30, 1998 and 1997, respectively.
During these periods, the Company's revenues from its GeoPlus and GeoShops
programs and revenue-sharing arrangements with commerce partners were non-
existent or individually insignificant as a percentage of net revenues. At
June 30, 1998, the Company had deferred revenues of $566,000. The Company
anticipates that advertising revenues will continue to account for a
substantial share of net revenues for the foreseeable future.     
 
  COST OF REVENUES
   
  Cost of revenues consists primarily of Internet connection charges, Web site
equipment leasing costs, depreciation, salaries of operations personnel and
other related operations costs. During the six months ended June 30, 1998 and
1997, cost of revenues related to the Company's premium service programs were
individually and collectively insignificant. Cost of revenues increased to
$3.9 million or 71% of net revenues for the six months ended June 30, 1998,
from $1.4 million or 87% of net revenues for the six months ended June 30,
1997. The absolute dollar increases in cost of revenues were primarily due to
building the Company's server and networking infrastructure in response to the
growth in number of Homesteads. Cost of revenues decreased as a percentage of
net revenues because of the growth in net revenues. The Company anticipates
that its Internet connection, Web site equipment and related operating costs
will continue to grow in absolute dollars for the foreseeable future.

OPERATING EXPENSES
 
  SALES AND MARKETING EXPENSES
   
  Sales and marketing expenses consist primarily of salaries of sales and
marketing personnel, commissions, advertising and other marketing related
expenses. Sales and marketing expenses also include personnel costs related to
editorial content and community management and support. Sales and marketing
expenses increased to $5.1 million or 92% of net revenues for the six months
ended June 30, 1998, from $2.1 million or 130% of net revenues for the six
months ended June 30, 1997. The absolute dollar increase in sales and
marketing expenses was primarily due to increases in the number of sales
personnel, increased sales commissions and increased expenses associated with
promotion and marketing efforts. Sales and marketing expenses as a percentage
of net revenues decreased because of the growth in net revenues. The Company
expects that sales and marketing expenses will grow significantly in absolute
dollars for the foreseeable future as it pursues an aggressive branding
strategy and hires additional sales and marketing personnel.     
 
  PRODUCT DEVELOPMENT EXPENSES
   
  Product development expenses consist primarily of salaries of certain
software development and operations personnel and expenditures related to
third party software. Product development expenses increased to $1.3 million
or 24% of net revenues for the six months ended June 30, 1998, from $437,000
or 27% of net revenues for the six months ended June 30, 1997. The absolute
dollar increase in product development expenses was primarily attributable to
increased personnel and associated software costs related to enhancing the
functionality of the Company's Web site. Product development expenses
decreased as a percentage of net revenues because of the growth in net
revenues. To date, all product development expenditures have been expensed as
incurred. The Company believes that significant investments in product
development are required to remain competitive. Therefore, the Company expects
that its product development expenses will continue to increase in absolute
dollars for the foreseeable future.     
 
  GENERAL AND ADMINISTRATIVE EXPENSES
   
  General and administrative expenses consist primarily of salaries and
related costs for general corporate functions, including finance, accounting,
facilities and legal, and fees for professional services. General and
administrative expenses increased to $2.9 million or 53% of net revenues for
the six months ended June 30, 1998, from $1.3 million or 78% of net revenues
for the six months ended June 30, 1997. The absolute dollar increase in
general and administrative expenses was primarily due to increases in the
number of personnel to support the growth of the Company's business, and
increases in recruiting costs related to filling key senior executive
positions. General and administrative expenses decreased as a percentage of
net revenues because of the growth in net revenues. The Company expects that
it will incur additional general and administrative expenses in absolute
dollars as the Company hires additional personnel and incurs additional
expenses related to the growth of the business and its operations as a public
company.     
 
 INTEREST INCOME (EXPENSE), NET
   
  Interest income (expense), net includes income from the Company's cash and
investments and expenses related to the Company's financing obligations.
Interest income (expense), net increased to $487,000 for the six months ended
June 30, 1998, from $69,000 for the six months ended June 30, 1997. The
increase in absolute dollars was primarily due to a higher average investment
balance as a result of the receipt of the proceeds of the issuance of shares
of the Company's preferred stock in October and December 1997.

YEAR ENDED DECEMBER 31, 1997, 1996 AND 1995
 
  NET REVENUES
   
  Net revenues were $4.6 million, $314,000 and $46,000 for the years ended
December 31, 1997, 1996 and 1995, respectively. The absolute dollar increases
from year to year were due primarily to an increase in the number of
advertisers, increase in traffic on the Company's Web site and, to a lesser
extent, increase in revenues from expansion of GeoPlus memberships.
Advertising revenues accounted for approximately 90.6%, 89.7%, and 0% of net
revenues in 1997, 1996 and 1995, respectively. The Company's four largest
advertising customers accounted for 29% and 40% of net revenues for the years
ended 1997 and 1996, respectively. For the years ended December 31, 1997 and
1996, the Company's other sources of net revenues, which included revenues
from premium services, were individually insignificant as a percentage of net
revenues. Prior to 1996, the Company's revenues were derived from commercial
Web site set-up and maintenance operations which were de-emphasized in early
1996 as the Company transitioned its business model toward building
advertising revenues.     
 
  COST OF REVENUES
   
  Cost of revenues were $4.6 million or 101% of net revenues, $788,000 or 251%
of net revenues and $103,000 or 224% of net revenues for the years ended
December 31, 1997, 1996 and 1995 respectively. Cost of revenues in 1997 and
1996 related to the Company's premium-service programs were individually
insignificant. Cost of revenues in 1995 consisted primarily of salaries of
design personnel and Internet connection charges. The absolute dollar
increases from year to year in cost of revenues were primarily due to the
costs of building the Company's server and networking infrastructure in
response to the growth in Homesteader membership. Cost of revenues as a
percentage of net revenues has decreased because of the growth in net
revenues.     
 
OPERATING EXPENSES
 
  SALES AND MARKETING EXPENSES
 
  Sales and marketing expenses were $5.0 million or 110% of net revenues,
$764,000 or 243% of net revenues and $117,000 or 254% of net revenues for the
years ended December 31, 1997, 1996 and 1995, respectively. The absolute
dollar increases from year to year in sales and marketing expenses were
primarily due to the addition of a direct sales force which the Company began
building in the second half of 1996 and increases in marketing expenses. Sales
and marketing expenses as a percentage of net revenues have decreased because
of the growth in net revenues.
 
  PRODUCT DEVELOPMENT EXPENSES
 
  Product development expenses were $1.0 million or 22% of net revenues,
$475,000 or 151% of net revenues and $72,000 or 157% of net revenues for the
years ended December 31, 1997, 1996 and 1995, respectively. The absolute
dollar increases from year to year in product development expenses were
primarily attributable to increases in the number of personnel and related
costs to support enhancement to the Company's products. Product development
expenses as a percentage of net revenues have decreased because of the growth
in net revenues.
 
  GENERAL AND ADMINISTRATIVE EXPENSES
 
  General and administrative expenses were $2.9 million or 63% of net
revenues, $1.3 million or 399% of net revenues and $233,000 or 507% of net
revenues for the years ended December 31, 1997, 1996 and 1995, respectively.
The absolute dollar increases from year to year in general and administrative
expenses were primarily due to increases in the number of general and

  INTEREST INCOME (EXPENSE), NET
 
  Interest income (expense), net was $117,000 for the year ended December 31,
1997. Interest income (expense), net was ($40,000) and ($2,000) for the years
ended December 31, 1996 and 1995, respectively. The increase in interest
income (expense), net for the year ended December 31, 1997 was primarily due
to a higher average investment balance as a result of preferred stock proceeds
from the first quarter and third quarter of 1997.
 
  INCOME TAXES
   
  As of December 31, 1997 the Company had approximately $11.3 million and
$10.7 million of federal and state net operating loss carryforwards,
respectively, for tax reporting purposes available to offset future taxable
income. The Company's federal and state net operating loss carryforwards
expire beginning 2010 and 2002, respectively. Due to the change in the
Company's ownership interests in 1996 and 1997, future utilization of the
Company's net operating loss carryforwards will be subject to certain
limitations or annual restrictions under the tax laws. See Note 9 of Notes to
Financial Statements.

  The Company's net revenues have increased in all quarters presented as a
result of an increase in the number of advertisers, the increase in the
Company's Web site traffic and, to a lesser extent, the expansion of the
Company's GeoPlus program. The increase in net revenues for the quarter ended
June 30, 1998, was due primarily to an increase in the number of advertisers,
an increase in revenues from the Company's premier commerce partners and the
addition of payments from third-party content providers.     
   
  Cost of revenues has increased in absolute dollars for each quarter
presented other than the quarter ended March 31, 1998. The increases in cost
of revenues in absolute dollars are the result of expanding the Company's
server and networking infrastructure to accommodate the growth in Homesteads
and increased traffic to the Company's Web site. The increase in cost of
revenues in absolute dollars for the quarter ended December 31, 1997 resulted
from the decision to change the Company's Internet service provider which
resulted in increased expenses during the transition period. The increase in
cost of revenues in absolute dollars for the quarter ended June 30, 1998, was
due to expansion of the Company's infrastructure to accommodate the increase
in the Company's Web site traffic and Homesteads and the costs associated with
increasing disk space available to Homesteads. The decrease in cost of
revenues as a percentage of net revenues for the quarter ended March 31 and
June 30, 1998, is a result of the growth in the Company's net revenues.     
   
  Operating expenses have increased in each of the quarters presented
reflecting the growth of the Company's operations. In addition, the increase
in sales and marketing expenses for the quarter ended June 30, 1998, was due
primarily to the addition of sales and marketing personnel, increased
commissions associated with higher sales and expenses related to increased
editorial content and community management and support. The increase in
general and administrative expenses for the quarter ended June 30, 1998,
primarily was due primarily to the expansion of the Company's corporate
infrastructure and legal expenses related to the FTC Proposed Consent Order.
Operating expenses as a percentage of net revenues have decreased as a result
of the growth in net revenues.     
 
  The Company's operating results may fluctuate significantly in the future as
a result of a variety of factors, many of which are outside of the Company's
control. These factors include demand for Web-based advertising, advertisers'
market acceptance of the Web as an advertising medium, the level of traffic on
the GeoCities Web site, the advertising budgeting cycles of advertisers, the
amount and timing of capital expenditures and other costs relating to the
expansion of the Company's operations, the introduction of new or enhanced
services by the Company or its competitors, the timing and number of new

of a key advertising contract or relationship by the Company, changes in the
Company's pricing policy or those of its competitors, the mix of types of
advertisements sold by the Company, engineering or development fees that may
be paid in connection with adding new Web site development and publishing
tools, technical difficulties with the GeoCities Web site, incurrence of costs
relating to future acquisitions, general economic conditions, and economic
conditions specific to the Internet or all or a portion of the technology
sector. As a strategic response to changes in the competitive environment, the
Company may from time to time make certain pricing, service or marketing
decisions or business combinations that could have a material adverse effect
on the Company's business, results of operations and financial condition. In
order to accelerate the promotion of the GeoCities brand, the Company intends
to significantly increase its marketing budget which could materially and
adversely affect the Company's business, results of operations and financial
condition for a number of quarterly periods. The Company has experienced, and
expects to continue to experience, seasonality in its business, with user
traffic on the GeoCities Web site being lower during the summer and year-end
vacation and holiday periods when overall usage of the Web is lower.
Additionally, seasonality may significantly affect the Company's advertising
revenues during the first and third calendar quarters, as advertisers
historically spend less during these periods. Because Web-based advertising is
an emerging market, additional seasonal and other patterns in Web advertising
may develop in the future as the market matures, and there can be no assurance
that such patterns will not have a material adverse effect on the Company's
business, results of operations and financial condition.
 
LIQUIDITY AND CAPITAL RESOURCES
   
  Since its inception, the Company has financed its operations primarily
through the private placement of its preferred stock and equipment lease
financing. As of June 30, 1998, the Company had approximately $1.2 million in
cash and cash equivalents and $19.2 million in short-term investments.     
   
  Net cash used in operating activities increased to $7.2 million for 1997
from $2.8 million for 1996, and increased to $6.3 million for the six months
ended June 30, 1998, compared to $3.7 million for the six months ended June
30, 1997. The increase in net cash used resulted primarily from increasing net
losses and accounts receivable, partially offset by increases in accrued
expenses.     
   
  Net cash used in investing activities increased to $1.3 million for 1997
from $130,000 for 1996, resulting from increased purchases of property and
equipment and the $645,000 investment in 40% of GeoCities Japan, a joint
venture with SOFTBANK. Net cash used in investing activities increased to
$21.3 million for the six months ended June 30, 1998, compared to $258,000 for
the six months ended June 30, 1997, resulting primarily from the purchase of
investments with the proceeds received in January 1998 from the Company's
issuance of shares of its preferred stock. The Company invested these proceeds
in debt securities, primarily U.S. Government and corporate debt securities,
with maturities not exceeding one year. The Company intends to continue to
invest its surplus funds in such securities.     
   
  Net cash provided by financing activities increased to $12.3 million for
1997 compared to $2.9 million for 1996 resulting primarily from the $13.0
million of cash proceeds from the sale of shares of the Company's preferred
stock for $38 million. Approximately $25.0 million of such preferred stock
proceeds were not received at December 31, 1997. The resulting $25.0 million
subscription receivable included in the financial statements at December 31,
1997, was subsequently received in January 1998. See Note 8 of Notes to
Financial Statements.     
 
  The Company has a bank line of credit for $10.0 million. To date there have
been no borrowings under this line of credit. This credit facility includes a
$7.0 million revolving facility for working capital and a $3.0 million lease
facility. This facility bears interest at the bank's prime rate for the
revolving facility and the bank's prime rate plus 0.75% for the lease
facility. Any borrowings under this line of credit will be collateralized by
substantially all of the Company's assets.

  In July 1998, the Company entered into an agreement to purchase certain Web-
page development technology for $850,000 in cash and, subject to the
technology being successfully installed and becoming operational on the
Company's servers to the Company's satisfaction within 90 days of the date of
the purchase agreement, $455,000 in Common Stock valued at the initial public
offering price. If the offering is not consummated within 90 days of the date
of the purchase agreement, such amount is payable in cash. In addition, if the
technology is successfully installed and becomes operational within an agreed-
upon period prior to the 90-day deadline, the Company will be required to pay
the seller an additional $145,000, payable in Common Stock or cash as set
forth above. If the technology is not successfully installed and does not
become operational on the Company's servers within 90 days of the date of the
agreement to the Company's satisfaction, the seller is obligated to refund to
the Company all but $300,000 of the cash payment.     
 
  The Company's capital requirements depend on numerous factors, including
market acceptance of the Company's services, the amount of resources the
Company devotes to investments in the GeoCities community, the resources the
Company devotes to marketing and selling its services and its brand promotions
and other factors. The Company has experienced a substantial increase in its
capital expenditures and operating lease arrangements since its inception
consistent with the growth in the Company's operations and staffing, and
anticipates that this will continue for the foreseeable future. Additionally,
the Company will continue to evaluate possible investments in businesses,
products and technologies, and plans to expand its sales and marketing
programs and conduct more aggressive brand promotions. The Company currently
anticipates that the net proceeds of the offering, together with its existing
line of credit and available funds will be sufficient to meet its anticipated
needs for working capital and capital expenditures for at least the next 12
months. See "Risk Factors--Future Capital Needs; Uncertainty of Additional
Financing".
 
  The Company is in the process of working with its software vendors to ensure
that the Company's systems are prepared for the year 2000. In addition, the
Company is working with its external suppliers and service providers to ensure
that they and their systems will be able to support the Company's needs in
preparation for the year 2000. Management does not anticipate that the Company
will incur significant operating expenses or be required to invest heavily in
computer systems improvements to be year 2000 compliant. However, significant
uncertainty exists concerning the potential costs and effects associated with
any year 2000 compliance. Any year 2000 compliance problems of either the
Company, its customers or vendors could have a material adverse effect on the
Company's business, results of operations and financial condition.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  In February 1997, Statement of Financial Accounting Standards ("SFAS") 128
"Earnings Per Share", was issued and effective for the Company's year ended
December 31, 1997. As a result, the Company's earnings per share ("EPS") data
for all periods has been presented in accordance with SFAS 128. In March 1997,
SFAS 129, "Disclosure of Information About Capital Structure", was issued and
will be effective for 1998. In June 1997, SFAS 130, "Comprehensive Income" and
SFAS 131, "Disclosure about Segments of an Enterprise", were issued and will
be effective for 1998. The Company is evaluating additional disclosures, if
any, which may result from these pronouncements. See Note 2 of Notes to
Financial Statements.

                                   BUSINESS
 
OVERVIEW
   
  GeoCities offers the world's largest and one of the fastest growing
communities of personal Web sites on the Internet. The Company pioneered the
first large-scale, Web-based community for Internet users to express
themselves, share ideas, interests and expertise, and publish content
accessible to other users with common interests. The mainstay of the Company's
community are its "Homesteaders," Internet users who create their own personal
Web sites or "Homesteads" in themed "neighborhoods" on the GeoCities Web site.
These neighborhoods provide a context for Web users to publish content, to
share experiences and ideas with other users and to access a centralized and
easy-to-navigate destination for user-published content.     
 
INDUSTRY BACKGROUND
 
 THE INTERNET AND WORLD WIDE WEB
   
  The Internet and the World Wide Web ("Web") have emerged as mass
communications and commerce mediums enabling millions of people worldwide to
share information, communicate and conduct business electronically.
International Data Corporation ("IDC") estimates that the number of Web users
worldwide will exceed 95 million by the end of 1998 and will grow to over 170
million users by the end of 2000. Jupiter Communications estimates that the
number of Internet-connected households worldwide will grow from approximately
45 million at the end of 1998 to approximately 66 million by the end of 2000.
The relatively lower costs required to publish content on the Web compared to
traditional media and the availability of powerful new tools for the
development and distribution of multimedia-rich content, including video and
audio, have led to a proliferation of more useful and engaging information and
services on the Internet. As the amount of content and services on the
Internet continues to grow at a rapid pace, greater numbers of Internet users
are attracted, fueling a cycle of growth wherein more users demand more
content and more content attracts more users.     
 
 THE NEED FOR ONLINE COMMUNITIES
 
  As the Internet continues to grow, users seek from the Web the same
opportunity for expression, interaction, sharing, support and recognition they
seek in the everyday world. To date, a typical Internet user's experience
surfing the Web has been essentially one-way--searching and viewing Web sites
containing professionally created content on topics of general interest such
as current events, sports, finance, politics and weather. However, the Web in
general does not provide a context for users to publish, promote, search and
view personal Web pages. As a result, users publishing personal Web sites have
had limited means of attracting visitors to their sites or interacting with or
receiving recognition from visitors. Internet search and navigational sites
serve a valuable function for users seeking to navigate the Internet for
aggregated Web content; however, these sites are not primarily focused on
providing a platform for publishing and aggregating the rapidly increasing
volume of personalized content created by users or enabling such users to
interact with each other--unique characteristics that distinguish the Internet
from traditional print, radio and television media. As a result, there is a
significant growing demand by Web users for an online community site in which
they can publish easy-to-find, context-based content for, interact with, and
be recognized by, other Web users.
 
  Similarly, Web users engaged in passive browsing are increasingly seeking
ways of interacting and communicating with other individuals with similar
interests and accessing unique, personalized content. While users are
generally able to obtain relevant professionally created content through
traditional navigational sites such as Web directories and search engines, the
source of such content is usually the media and not fellow Web users. Often,
the most relevant content for a user is generated by other users who share an
interest in what is published; however, most Web sites are not dedicated to
providing a platform for aggregating and accessing user-created content.
Online communities, unlike
 
                                      39
<PAGE>
 
traditional Web navigational or content sites, provide the user with the
ability to directly interact with the author of such personalized content. As
a result, there is a significant and growing demand among users surfing the
Internet for an online community site that offers a centralized means of
accessing diverse, personally created content in an easy-to-navigate
contextual manner.
   
  Online communities also provide advertisers and businesses an attractive
means of promoting and selling their products and services. According to
Jupiter Communications, the amount of advertising dollars spent on the Web is
expected to increase 67% annually over the next three years, reaching
approximately $4.3 billion by 2000. According to IDC, worldwide commerce
revenue on the Internet is expected to increase from approximately $32 billion
in 1998 to approximately $130 billion in 2000. To date, advertisers and
businesses have typically used traditional navigational sites and
professionally created content sites to promote their products and services
online. However, online communities allow advertisers and businesses to reach
highly targeted audiences within a more personalized context, thus providing
the opportunity to increase advertising efficiency and improve the likelihood
of a successful sale.     
 
THE GEOCITIES SOLUTION
   
  Founded by David Bohnett, GeoCities pioneered the first large-scale, Web-
based community for users to express themselves, share ideas, interests and
expertise and publish content accessible to other users with common interests.
The Company believed that user affinity to the Web occurs when users relate
personally to their online experience, and the more active users are in the
creation of that experience, the more personal the experience becomes. To
attract members to its community, the Company established a service enabling
Internet users to create their own Web sites in themed "neighborhoods" on the
GeoCities Web site. These neighborhoods provide a context for Web users to
publish content, to share experiences and ideas with other users and to access
a centralized and easy-to-navigate destination for user-created content.     
   
  Since its inception, GeoCities has become the world's largest and one of the
fastest growing communities of personal Web sites on the Internet. With
thousands of Homesteaders joining each day, the GeoCities community has grown
from approximately 10,000 Homesteads in October 1995 to over 2.1 million in
July 1998. Homesteaders have created an estimated 17 million pages of
personalized content, attracting over 14.8 million unique visitors to, and
generating over 925 million page views on, the GeoCities community, according
to Relevant Knowledge in June 1998 and Nielsen I/PRO in May 1998,
respectively. GeoCities was the third most trafficked Web site on the Internet
among home users in June 1998, according to Media Metrix, and, based on this
information, the Company believes it was the most popular community of
personal Web sites on the Internet during the first two quarters of 1998.     
   
  The Company believes that its success to date is attributable to its focus
on Homesteaders, visitors and advertising and commerce partners. This focus is
highlighted by the following distinguishing characteristics of the GeoCities
community:     
 
  LARGE WEB-BASED COMMUNITY WITH BROAD RANGE OF NEIGHBORHOODS. Homesteaders
are able to join one of 40 themed GeoCities neighborhoods, which are organized
topically, based on themes associated with well-known places. By providing
this broad range of neighborhoods for Homesteaders, GeoCities fosters a
virtual "greenhouse" for a wide range of individual self-expression and
interaction. Web users interested in finance and investing, for example,
Homestead in and create content for WallStreet and those interested in
politics Homestead in and support CapitolHill. Moreover, as the Internet's
largest community of personal Web sites, GeoCities offers on average over
40,000 Homesteads within each of its neighborhoods, providing Homesteaders
with the critical mass and platform to interact with and be recognized by
others.
 
                                      40
<PAGE>
 
  ACTIVE OWNERSHIP AND COMMUNITY PARTICIPATION. GeoCities encourages active
participation in its community and offers a number of programs to increase
levels of participation. When Homesteaders first apply to join a GeoCities
neighborhood, they agree to abide by the GeoCities community guidelines.
Homesteaders also agree to begin creation of their Web sites within two weeks
of joining a GeoCities neighborhood or relinquish their Homesteads.
Additionally, the Company welcomes suggestions from its Homesteaders and
implements those ideas that improve the community. As a result, the Company's
Homesteaders develop a keen sense of personal involvement in and ownership of
the GeoCities community, and actively encourage others to join and
participate. Homesteaders seeking greater involvement in their neighborhoods
are given the opportunity to join the active ranks of 40 Community Liaisons
and over one thousand Community Leaders. The Community Liaison and Community
Leaders within each neighborhood welcome new Homesteaders, provide assistance
to other Homesteaders, actively provide GeoCities with suggestions for
improvements and monitor sites. The Company believes that the greater the
involvement of its Homesteaders, the greater the loyalty and affinity of those
Homesteaders to the GeoCities site, and the more successful the GeoCities
community.
 
  FOCUS ON CONTINUALLY IMPROVING THE HOMESTEADER EXPERIENCE. GeoCities
continually strives to improve the online experience of its members.
Homesteaders are provided free of charge with disk space for personal Web
sites, powerful Web-page publishing and communication tools to create their
own fully customized, multimedia-rich content and e-mail, chat and bulletin
board services. The Company offers premium memberships for Homesteaders who
want more utilities, disk space and a personal URL. GeoCities holds a monthly
conference call with its Community Liaisons in order to proactively determine
what improvements and suggestions are important to its GeoCities community. By
supplementing this call with a weekly newsletter for Community Leaders,
GeoCities maintains close interaction with its community on issues and
suggestions of a broader group of Homesteaders. In addition, the Company
offers a comprehensive online help function and encourages volunteerism among
its Community Leaders and Liaisons and other Homesteaders in helping their
GeoCities neighbors.
   
  INTUITIVE MEANS OF FINDING PERSONALIZED CONTENT. While Internet users can
generally find Web content aggregated by subject area, aggregated user-created
content is much more challenging to find. GeoCities' topical categorization of
user-created content provides visitors with a central online site for quickly
accessing a critical mass of an estimated 17 million pages of personalized
content. Given their strong affinity for their Homestead and the GeoCities
community, Homesteaders actively promote their Web sites throughout the
Internet with hyperlinks located on other individual sites as well as through
listings on Internet directories and search engines, thereby resulting in
millions of Internet users visiting the GeoCities community site.     
 
  UNIQUE PERSONALIZED COMMUNITY ENVIRONMENT FOR ADVERTISING AND
COMMERCE. Online communities of members with common interests and demographics
constitute attractive opportunities for advertisers seeking to promote their
products and services online and businesses desiring to conduct commerce on
the Internet. The combination of GeoCities' unique community context,
intuitive topical organization, high volumes of traffic and Homesteaders'
acceptance of the role of advertising in the community provides an attractive
platform for targeted and cost-effective Web advertising and Web commerce.

THE GEOCITIES STRATEGY
 
  The Company's objective is to be the world's leading member-created online
community for people on the Web. The Company's strategies to achieve this
objective include:
   
  FOCUS ON HOMESTEADER GROWTH AND AFFINITY. The Company intends to continue to
increase the number of its Homesteaders and concentrate on member affinity to
maintain its position as a leading community of personal Web sites. The
Company intends to continue to grow its membership base by: (i) introducing
additional classes of membership that appeal to a broader range of Internet
users; (ii) offering easier-to-use Web-page publishing tools, allowing
Homesteaders to easily create and enhance personal Web sites; (iii) promoting
GeoCities as a destination point on the Web by augmenting its existing
distribution alliances with Yahoo! and other partners and (iv) launching
brand- name promotional campaigns to drive both growth in membership and
traffic to its members' personal Web sites. In addition, the Company intends
to introduce more value-added member services and strengthen and expand the
number of affinity programs offered by the Company, including its GeoRewards
affinity program. Similar to airline frequent-flyer bonus point programs, the
GeoRewards affinity program is designed to reward Homesteaders with points
based on their level of participation, which they can later redeem for
discounts on purchases within the GeoCities community. The Company believes
that its focus on the needs of its Homesteaders and enhancing their experience
within the GeoCities community will produce continued growth in, and foster
loyalty among its membership base. The Company believes that a large and
growing base of committed Homesteaders organized on a contextual basis
provides advertisers and businesses with an attractive market to target
promotion of their products and services, thereby creating advertising and
commerce revenue opportunities for the Company.     
   
  BUILD THE GEOCITIES BRAND. The Company intends to increase its focus on
building the GeoCities brand. Historically, the Company's growth has been
primarily by word of mouth and the informal promotional efforts of its
members. Following the offering, the Company intends to launch an aggressive
promotional campaign to increase awareness of the GeoCities brand through
traditional media, including print, radio, billboard and television. In
addition, the Company intends to pursue additional distribution arrangements
to increase its reach on the Internet and introduce a number of additional
brand awareness programs on the GeoCities site to leverage its large and
growing Homesteader base and visitor traffic. The Company believes that a
well-recognized GeoCities brand will be attractive to existing and potential
advertising customers and commerce partners of the Company.     
   
  CONTINUE TO ENHANCE SITE FUNCTIONALITY AND PERFORMANCE. The Company believes
continually providing Homesteaders and visitors with greater functionality and
performance is critical to its continued leadership. The Company introduced a
new user interface in May 1998, which offers substantially improved
presentation of member-generated content in an intuitive topical format and
has been well received by the Company's Homesteaders and visitors to the
GeoCities community. The Company recently integrated third-party news and
editorial content into its site, allowing side-by-side interaction of personal
and professionally published content. In addition, the Company will utilize
proceeds from the offering to continue to upgrade and expand its server and
networking infrastructure, improving its ability to provide fast and reliable
access to the GeoCities community. The Company will also continue to provide
its members with enhanced Web-page publishing and communication tools to
enhance the community experience. The Company believes that continually-
enhancing site functionality and performance foster Homesteader and visitor
growth and affinity to the GeoCities community, thereby providing the Company
with an attractive platform for advertisers and for expansion of its
fee-generating premium membership services.     
 
                                      42
<PAGE>
 
  ESTABLISH NEW STRATEGIC ALLIANCES. The Company has formed a number of
strategic relationships, including a distribution and equity relationship with
Yahoo! intended to increase traffic and memberships of both partners, in
addition to offering GeoCities' Homesteaders an array of free personalized
member services on Yahoo!. The Company has also formed four premier commerce
relationships with Amazon.com for books, CDnow for compact discs, First USA
for credit cards and Surplus Direct/Egghead for software and computer
hardware, making the products and services of these leading Internet vendors
available throughout the GeoCities community. These relationships provide an
opportunity for the Company to receive monthly payments and share in any
ongoing revenue streams from sales of products and services by these partners.
The Company intends to seek additional strategic relationships with commerce
and distribution partners.
   
  EXPAND GLOBALLY. The Company believes that the anticipated growth of
Internet usage internationally presents significant opportunities to extend
GeoCities globally. According to Jupiter Communications, the number of online
households in the Asia/Pacific Rim and Europe is expected to reach
approximately 15 million at the end of 1998 and is expected to grow to
approximately 26 million by 2000. GeoCities is focused on establishing the
GeoCities community and brand in Japan, a market which, according to Jupiter
Communications, is second only to the United States in terms of Internet use.
Accordingly, the Company has entered into a joint venture with SOFTBANK to
form GeoCities Japan, which is 40% owned by the Company. The Company intends
to pursue additional opportunities for international expansion. The Company
believes that the introduction of localized GeoCities Web communities in
international markets will present many of the same opportunities for
advertising and commerce revenue as those in the United States.     
 
  BUILD MULTIPLE REVENUE STREAMS. The Company's large and growing Web
community offers a scalable business platform from which the Company plans to
generate revenue from multiple sources, including advertising, commerce and
premium membership service fees. The Company intends to achieve its revenue
objectives by: (i) increasing its advertising revenues through expansion of
its customer base, increasing the rates it charges advertisers by continuing
to improve its ability to target advertisements to more demographically
distinct groups, increasing its page views, increasing the average size and
length of its advertising contracts, increasing the number of its direct sales
representatives and continuing to invest in improving ad serving and ad
targeting technology; (ii) expanding its revenue-sharing commerce
relationships and its relationships with third-party content providers that
pay the Company for access to its site; (iii) promoting its GeoShops program,
which is designed to provide an effective means for small and home business
owners to leverage the reach of the Internet through a commercial presence
within the GeoCities community and (iv) expanding the number and scope of its
fee-based premium membership services.
 
HOMESTEADING ON GEOCITIES
   
  GeoCities distinguishes itself from other Web sites by offering Homesteaders
a diverse range of neighborhoods and a critical mass of neighbors with whom to
interact. The Company also promotes active Homesteader participation through
its member-focused editorial philosophy--millions of personal Web pages
created and maintained by the community members themselves--providing Internet
users with a platform for contributing their talents and ideas, meeting and
interacting with others with similar interests and creating their own "home on
the Web". Supporting the editorial efforts of its Homesteaders are
approximately 45 GeoCities employees dedicated exclusively to community
organization, content management and community interaction. GeoCities provides
disk space, powerful Web-page publishing tools, customer support, high-speed,
high-quality site performance and e-mail, chat and bulletin-board services,
all free of charge.     
 
  The Company emphasizes a sense of responsibility among community members by
leveraging the characteristics of the Web that users find most attractive--
connection, expression, communication, entertainment and utility. GeoCities
Homesteaders abide by the community values--respect for the
 
                                      43
<PAGE>
 
individual, open and honest communication, encouragement of ethical behavior
and respect for diverse points of view--reflected in the Company's content
guidelines and rules of conduct. GeoCities appeals to people's interest in
others by inviting users to move in, meet their neighbors, share ideas,
communicate, shop, check e-mail and join its growing community.
 
  HOW HOMESTEADERS JOIN
 
  GeoCities' 40 themed neighborhoods--virtual communities of people with
common interests--are based on familiar themes and provide Web users with a
place to connect on the Internet. Homesteading is analogous to moving to a new
community, picking a neighborhood to live in and designing and building a new
home to reflect one's own style and tastes. Each Homesteader is able to join
the neighborhood that most closely matches his or her interests. For example,
Homesteaders interested in music join and contribute to SunsetStrip and those
interested in wine support NapaValley. Homesteading in the GeoCities community
is designed to be easy and fun. After choosing a neighborhood, Homesteaders
find a vacant address, fill out an application, move-in and commence
developing their personal Web site. Homesteaders agree to abide by the
community guidelines and begin construction of their home within two weeks of
moving into a neighborhood. The Homesteading experience makes a user's online
experience expressive, interactive and personal.
 
  PARTICIPATING IN THE GEOCITIES COMMUNITY
   
  After joining a neighborhood, Homesteaders are encouraged to become active
in the community. Members can interact with their neighbors, support community
building initiatives, participate in chat sessions with their neighbors and
collaborate on editorial content. The Company believes that the more
Homesteaders participate, the more attachment they feel to the community and
the higher the quality of their content. Homesteaders seeking greater
involvement apply to become Community Leaders and Community Liaisons.
GeoCities currently has over one thousand Community Leaders, who are elected
by Homesteaders, and 40 Community Liaisons, who represent a neighborhood and
are elected by Community Leaders. The Community Leaders and Community Liaisons
are highly valued community builders who greet and assist new Homesteaders,
mentor other Homesteaders, coordinate neighborhood activities, interface with
the Company's in-house editorial staff and work to foster core community
values. In recognition of this valued service, Community Leaders and Liaisons
will receive a stock grant under the Company's 1998 Stock Incentive Plan. The
Company intends to introduce additional community leadership positions in the
future to increase levels of community participation. The Company also
encourages greater Homesteader involvement through its GeoRewards affinity
program. Homesteaders accrue bonus points based on their level of
participation which they can later redeem for discounts on purchases within
the GeoCities community.     
 
  HOW TO SURF THE GEOCITIES COMMUNITY
 
  The Company believes that it provides users surfing the Web with a
comprehensive, high-quality concentration of personal Web sites on the
Internet. The Company strives to improve its site for such users by upgrading
the look and feel of its Web site to provide easier navigation of and to
direct greater levels of traffic to Homesteaders' Web sites. In May 1998, the
Company introduced its new user interface designed to be easier to use and
highly intuitive. The new user interface presents the GeoCities Web site to
visitors in a topical format to facilitate the aggregation of categories of
interests. This format allows easier and more intuitive access to content on
the GeoCities Web site and enhances the integration of Homesteaders' content
with the Company's e-mail, chat, bulletin-board services and selected third-
party content such as news and editorial feeds from Reuters, Women.com and
ZDNet.

ADVERTISING, COMMERCE AND PREMIUM SERVICES
 
  ADVERTISING
   
  The Company has built a direct sales organization of 18 professionals as of
June 30, 1998, located in New York, San Francisco and Los Angeles, which is
dedicated to maintaining close relationships with top advertisers and leading
advertising agencies nationwide. The Company's direct sales organization is
organized regionally and is focused solely on selling advertising on the
GeoCities Web site. The Company also has arrangements with a number of third-
party advertising sales representatives pursuant to short-term agreements that
in general may be terminated by either party, without notice or penalty. The
Company's sales organization consults regularly with advertisers and agencies
on design and placement of their Web-based advertising, provides customers with
advertising measurement analysis and focuses on providing a high level of
customer service and satisfaction.     
 
  Currently, advertisers and advertising agencies enter into short-term
agreements, on average one to two months, pursuant to which they receive a
guaranteed number of impressions for a fixed fee. Advertising in GeoCities
currently consists primarily of banner-style advertisements that are
prominently displayed at the top of pages on a rotating basis throughout the
GeoCities community, including members' personal Web sites. From each banner
advertisement, viewers can hyperlink directly to the advertiser's own Web site,
thus providing the advertiser an opportunity to directly interact with an
interested customer. The Company's standard cost per thousand impressions
("CPM") for banner advertisements currently ranges from $15 to $40, depending
upon location of the advertisement and the extent to which it is targeted for a
particular audience. Discounts from standard CPM rates may be provided for
higher volume, longer-term advertising contracts.
 
  The Company intends to increase its advertising revenues by focusing on a
number of key strategies, including expanding its advertising customer base,
increasing the CPM it charges advertisers by continuing to improve its ability
to target advertisements to demographically distinct groups, increasing page
views, increasing the average size and length of its advertising contracts,
increasing the number of its direct sales representatives and continuing to
invest in improving ad serving and ad targeting technology.
 
  The Company also offers special sponsorship and promotional advertising
programs, such as contests, sampling and couponing opportunities to build brand
awareness, generate leads and drive traffic to an advertiser's site. The
Company also sells sponsorships of special interest pages where topically
focused content is aggregated on a permanent area within a neighborhood. The
Company has also recently entered into relationships with third-party Internet
content providers, many of whom pay GeoCities for integrating their content
within the GeoCities community. The Company will also seek to expand its third-
party content-provider relationships.
   
  The Company has derived a substantial majority of its revenues to date from
the sale of advertisements. For 1997 and the six months ended June 30, 1998,
advertising revenues represented 90.6% and 90.2%, respectively, of the
Company's net revenues.     
 
  ADVERTISING CUSTOMERS
   
  During the six months ended June 30, 1998, approximately 170 companies
advertised on the GeoCities Web site compared to approximately 80 advertisers
for the same six-month period in 1997. The following is a selected list of
certain of the Company's advertising customers for the 18-month period ended
June 30, 1998:     
 
    Amazon.com                  Hewlett-Packard            Surplus
    American Express            Honda                      Direct/Egghead
    AT&T                        IBM                        Toyota
    CDnow                       Microsoft                  USA Net
    Dell Computers              SkyTel                     Visa
    General Motors              Sony                       ZDNet
 
                                       45
<PAGE>
 
   
  During 1997 and the six months ended June 30, 1998, the Company's four
largest customers accounted for approximately 29% and 28%, respectively, of
the Company's net revenues. During these same periods, Surplus Direct/Egghead
accounted for approximately 12% and 10%, respectively, of the Company's net
revenues. No other customer accounted for more than 10% of the Company's net
revenues during either of such periods.     
 
  COMMERCE PARTNERS
 
  GeoCities believes Web commerce fits naturally into the Company's community
model. Through Web commerce, the Company partners with merchants and service
providers to integrate their products and services into the GeoCities
community, making them available for sale to the Company's Homesteaders and
visitors. In its premier commerce arrangements, the Company generally receives
a fixed monthly fee and a share of the proceeds from any online sales. In
addition, certain of the Company's premier commerce partners pay GeoCities
fees for Homesteader participation in vendor-sponsored sales programs after a
minimum level of participation has been achieved. To date, the Company has
entered into four premier alliances with commerce partners that are given
access to GeoCities' community platform and are provided with premier banner
and other space in permanent locations on select community Web pages. These
premier commerce arrangements typically have one-year terms and, subject to
the payment of certain fees, are renewable at the option of the Company's
commerce partners.
 
  The Company has established premier commerce relationships with the
following entities:
 
  .  Amazon.com--providing GeoCities' Homesteaders and visitors with the
     opportunity to purchase books throughout the Company's Web site;
 
  .  CDnow--providing GeoCities' Homesteaders and visitors with the
     opportunity to purchase compact discs and other music-related items;
 
  .  Surplus Direct/Egghead--providing GeoCities' members and visitors with
     the opportunity to purchase software and computer hardware; and
 
  .  First USA--providing GeoCities' members and visitors with an opportunity
     to apply for a First USA credit card.
 
  GEOSHOPS
 
  In March 1998, GeoCities introduced GeoShops, its member-focused Web
commerce solution designed to provide a range of services which commerce-
enable Homesteaders' personal Web sites. Homesteaders are able to choose
between two GeoShops options: (i) for a $24.95 monthly fee, GeoShops allows
GeoCities members to sell products and services from their personal Web sites
within the GeoCities community and (ii) for a set-up fee of $120, a per
transaction fee and an additional monthly amount equal to the greater of $80,
or $40 plus a 5% commission on sales, GeoCities provides Homesteaders with a
transaction authentication and processing solution for their Web-based
businesses. With its GeoShops program, the Company enables home-based
businesses to leverage a fast, effective, easy-to-use program for commerce,
and the Company intends to actively promote this service in the future.
 
  GEOPLUS
   
  In addition to its free services, the Company offers a fee-based premium
service for its Homesteaders. For a fee of $4.95 per month, the Company's
GeoPlus service provides enhanced Web-page publishing tools for creating more
robust content, a personalized URL (Universe Resource Locator that determines
the particular location of a Web page on the Internet) and up to 25 megabytes
of disk space for Homesteaders' personal Web sites. GeoCities intends to
introduce additional features and premium service levels to appeal to a
broader range of Homesteaders. The Company does not generate revenues from
general Internet access or subscription fees.

MARKETING AND BRAND AWARENESS
 
  Historically, the Company's marketing has been primarily by word of mouth
and the informal promotional efforts of Homesteaders. The Company believes
initiating a formal, aggressive brand promotional campaign will provide the
Company with a significant opportunity for growing its Homesteader membership
base as well as attracting additional advertisers and commerce partners. The
Company intends to use a portion of the net proceeds from the offering to
launch a number of promotional campaigns in traditional media, including
print, radio, billboard and television, all designed to increase traffic and
brand awareness and an understanding of the Company's community model. The
Company also intends to introduce a number of other brand awareness programs
on its own site to leverage its large and growing Homesteader base and visitor
traffic. In addition, the Company plans to launch a number of grassroots
marketing efforts, including, for example, augmenting its existing GeoRewards
affinity program with additional membership affinity programs, as well as
continuing the promotion of its GeoPlus and GeoShops programs.
 
DISTRIBUTION AGREEMENT WITH YAHOO!
   
  In December 1997, the Company entered into a one-year distribution
relationship with Yahoo! which is renewable for subsequent one-year terms,
subject to the right of either party to terminate the relationship at the end
of any term upon 90-days' notice. In connection with the distribution
agreement, Yahoo! also made a minority equity investment in the Company. As of
June 30, 1998, Yahoo! held 2.6% of the Company's outstanding capital stock.
This Agreement was designed to increase traffic and memberships of both
parties in addition to offering GeoCities' Homesteaders an array of free
personalized member services on Yahoo!. Under the terms of the agreement,
GeoCities agreed to provide its community-based, Web services for free to
registered users of Yahoo!. In addition, Yahoo! agreed to market GeoCities'
branded personal publishing programs on select areas throughout Yahoo!, as
well as provide a GeoCities-specific programming module on My Yahoo! for
GeoCities' Homesteaders. There can be no assurance that the agreement with
Yahoo! will be renewed.     
 
  The Company intends to seek additional strategic alliances with distribution
partners to increase the number of gateways into the GeoCities community and
Homesteader Web sites, thus increasing its overall visibility on the Web.
 
INFRASTRUCTURE AND OPERATIONS
   
  The Company has developed an open standard hardware and software system that
is designed to be reliable and responsive. The Company's third-generation
architecture is a scalable system which includes over five terabytes of raw
disk space and supports over 170 million hits per day, has a peak bandwidth of
over 340 megabits per second and transfers 1.7 terabytes of data each day. The
Company provides its Homesteaders and visitors with a robust content platform
containing an estimated 17 million pages of user-created content that
generated over 925 million page views in June 1998, according to Nielsen
I/PRO.     
 
  The Company provides an efficient, responsive user experience through
network servers housed in Santa Clara, California, third-party and public
domain server software optimized internally by the Company and internally
developed tools and utilities. Requests for files to GeoCities are distributed
to the appropriate servers using Resonate Dispatch load distribution and
balancing software. Member-generated content is stored on a redundant array of
independent disks, is backed up to long-term tape storage devices on a daily
basis and copied on a weekly basis to be stored offsite. User profile
information is stored on multiple disk arrays using Informix Dynamic Server
database software and backed up to long-term tape storage devices on a semi-
hourly basis. The Company will continue to upgrade and expand its server and
networking infrastructure in an effort to improve its fast and reliable access
to the Company's community.

<PAGE>
 
  Site connectivity to the Internet is provided via multiple DS-3 and OC-3
links on a 24 hour-a-day, seven days per week basis by Exodus. Exodus also
provides and manages power and environmentals for the Company's networking and
server equipment. The Company manages and monitors its servers and network
remotely from its headquarters in Santa Monica, California. The Company
strives to rapidly develop and deploy high-quality tools and features into its
system without interruption or degradation in service. Any disruption in the
Internet access provided by Exodus, or any interruption in the service that
Exodus receives from other providers, or any failure of Exodus to handle
higher volumes of Internet users to the GeoCities' site could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
COMPETITION
   
  The market for members, visitors and Internet advertising is new and rapidly
evolving, and competition for members, visitors and advertisers is intense and
is expected to increase significantly in the future. Barriers to entry are
relatively insubstantial. The Company believes that the principal competitive
factors for companies seeking to create community on the Internet are critical
mass, functionality, brand recognition, member affinity and loyalty, broad
demographic focus and open access to visitors. Other companies who are
primarily focused on creating Web-based community on the Internet are
Tripod/Lycos, Angelfire, Xoom and theglobe. The Company will likely also face
competition in the future from Web directories, search engines, shareware
archives, content sites, commercial online services, sites maintained by ISPs
and other entities that attempt to or establish communities on the Internet by
developing their own or purchasing one of the Company's competitors. In
addition, the Company could face competition in the future from traditional
media companies, a number of which, including Disney, CBS and NBC, have
recently made significant acquisitions of or investments in Internet
companies. Further, there can be no assurance that the Company's competitors
and potential competitors will not develop communities that are equal or
superior to those of the Company or that achieve greater market acceptance
than the Company's community. The Company also competes for visitors with many
Internet content providers and ISPs, including Web directories, search
engines, shareware archives, content sites, commercial online services and
sites maintained by ISPs, as well as thousands of Internet sites operated by
individuals and government and educational institutions. These competitors
include free information, search and content sites or services, such as AOL,
CNET, CNN/Time Warner, Excite, Infoseek, Lycos, Netscape, Microsoft and
Yahoo!, some of whom, such as Yahoo! and Lycos, also have relationships with
GeoCities. The Company also competes with the foregoing companies, as well as
traditional forms of media such as newspapers, magazines, radio and
television, for advertisers and advertising revenue. The Company believes that
the principal competitive factors in attracting advertisers include the amount
of traffic on its Web site, brand recognition, customer service, the
demographics of the Company's members and viewers, the Company's ability to
offer targeted audiences and the overall cost-effectiveness of the advertising
medium offered by the Company. The Company believes that the number of
Internet companies relying on Web-based advertising revenue will increase
greatly in the future. Accordingly, the Company will likely face increased
competition, resulting in increased pricing pressures on its advertising rates
which could in turn have a material adverse effect on the Company's business,
results of operations and financial condition.     
 
  Many of the Company's existing and potential competitors, including Web
directories and search engines and large traditional media companies, have
longer operating histories in the Web market, greater name recognition, larger
customer bases and significantly greater financial, technical and marketing
resources than the Company. Such competitors are able to undertake more
extensive marketing campaigns for their brands and services, adopt more
aggressive advertising pricing policies and make more attractive offers to
potential employees, distribution partners, commerce companies, advertisers
and third party content providers. There can be no assurance that Internet
content providers and ISPs, including Web directories, search engines,
shareware archives, sites that offer professional editorial content,
commercial online services and sites maintained by ISPs will not be
 
                                      48
<PAGE>
 
perceived by advertisers as having more desirable Web sites for placement of
advertisements. In addition, substantially all of the Company's current
advertising customers and strategic partners also have established
collaborative relationships with certain of the Company's competitors or
potential competitors, and other high-traffic Web sites. Accordingly, there
can be no assurance that the Company will be able to grow its memberships,
traffic levels and advertiser customer base at historical levels or retain its
current members, traffic levels or advertiser customers, or that competitors
will not experience greater growth in traffic than the Company as a result of
such relationships which could have the effect of making their Web sites more
attractive to advertisers, or that the Company's strategic partners will not
sever or will elect not to renew their agreements with the Company. There can
also be no assurance that the Company will be able to compete successfully
against its current or future competitors or that competition will not have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
  The Company regards its technology as proprietary and attempts to protect it
by relying on trademark, service mark, copyright and trade secret laws and
restrictions on disclosure and transferring title and other methods. The
Company currently has no patents or patents pending and does not anticipate
that patents will become a significant part of the Company's intellectual
property in the foreseeable future. The Company also generally enters into
confidentiality or license agreements with its employees and consultants, and
generally controls access to and distribution of its documentation and other
proprietary information. Despite these precautions, it may be possible for a
third party to copy or otherwise obtain and use the Company's proprietary
information without authorization or to develop similar technology
independently. The Company pursues the registration of its service marks in
the United States and internationally, and has applied for and obtained the
registration in the United States for a number of its service marks, including
"GeoCities". Effective trademark, service mark, copyright and trade secret
protection may not be available in every country in which the Company's
services are distributed or made available through the Internet, and policing
unauthorized use of the Company's proprietary information is difficult.
   
  Legal standards relating to the validity, enforceability and scope of
protection of certain proprietary rights in Internet-related businesses are
uncertain and still evolving, and no assurance can be given as to the future
viability or value of any proprietary rights of the Company or other companies
within this market. There can be no assurance that the steps taken by the
Company will prevent misappropriation or infringement of its proprietary
information. Any such infringement or misappropriation, should it occur, might
have a material adverse effect on the Company's business, results of
operations and financial condition. In addition, litigation may be necessary
in the future to enforce the Company's intellectual property rights, to
protect the Company's trade secrets or to determine the validity and scope of
the proprietary rights of others. Such litigation might result in substantial
costs and diversion of resources and management attention and could have a
material adverse effect on the Company's business, results of operations and
financial condition. Furthermore, there can be no assurance that the Company's
business activities will not infringe upon the proprietary rights of others,
or that other parties will not assert infringement claims against the Company.
From time to time, the Company has been, and expects to continue to be,
subject to claims in the ordinary course of its business including claims of
alleged infringement of the copyrights, trademarks, service marks and other
intellectual property rights of third parties by the Company and the content
generated by its members. Although such claims have not resulted in
significant litigation or had a material adverse effect on the Company's
business to date, such claims and any resultant litigation, should it occur,
might subject the Company to significant liability for damages and might
result in invalidation of the Company's proprietary rights and even if not
meritorious, could be time consuming and expensive to defend and could result
in the diversion of management time and attention, any of which might have a
material adverse effect on the Company's business, results of operations and
financial condition.     
 
 
                                      49
<PAGE>
 
   
  The Company currently licenses from third parties certain technologies
incorporated into the Company's Web site, including a site license for its
database software. The Company relies on the licensed software under this site
license to manage the storage and retrieval of Homesteader information,
including Homesteader names, e-mail addresses, passwords and usage
information. This site license remains in effect until it is terminated by
either party. The site license also terminates in certain other circumstances,
including in the event of a breach by either party. Although the Company
believes that it could obtain an alternative site license for its database
software should this site license terminate for any reason, any such
termination would have a disruptive effect on the Company's ability to manage
the storage and retrieval of Homesteader information for a period of time.
       
  As it continues to introduce new services that incorporate new technologies,
it may be required to license additional technology from others. There can be
no assurance that these third-party technology licenses will continue to be
available to the Company on commercially reasonable terms, if at all. The
inability of the Company to obtain any of these technology licenses could
result in delays or reductions in the introduction of new services or could
adversely affect the performance of its existing services until equivalent
technology could be identified, licensed and integrated.     
 
EMPLOYEES
   
  As of June 30, 1998, the Company had 152 full-time employees, including 45
in marketing and sales, 37 in editorial, 23 in finance and administration and
47 in operations and support. The Company's future success will depend, in
part, on its ability to continue to attract, retain and motivate highly
qualified technical and management personnel, for whom competition is intense.
From time to time, the Company also employs independent contractors to support
its research and development, marketing, sales and support and administrative
organizations. The Company's employees are not represented by any collective
bargaining unit, and the Company has never experienced a work stoppage. The
Company believes its relations with its employees are good.     
 
FACILITIES
   
  The Company's headquarters are currently located in a leased facility in
Santa Monica, California, consisting of approximately 13,000 square feet of
office space, a majority of which is under a five-year lease, and has a
renewal option for an additional three years. The Company intends to relocate
its headquarters in the near future to a leased facility in Marina del Rey,
California consisting of approximately 24,000 square feet of office space. The
new facility will be under a five-year lease and will have two renewal
options, each for an additional three years. The Company has also leased
approximately 5,500  square feet of office space in New York and approximately
1,700 square feet of office space in San Francisco for its East and West Coast
sales offices, respectively.

(1) In April 1998, Mr. Evans was granted two options to purchase up to an

    280,000 shares of Common Stock at an exercise price of $0.75 per share.
    These options expire in September 2004.     
(2) Each option represents the right to purchase one share of Common Stock.
    The options shown in this column are all nonqualified stock options. The
    options become exercisable in four equal annual installments commencing
    one year after the date of grant. To the extent not already exercisable,
    all of these options will become exercisable in the event of a merger in
    which the Company is not the surviving corporation or upon the sale of
    substantially all the Company's assets. In addition, upon the termination
    of Mr. Bohnett's employment for any reason, his options will, to the
    extent not already exercisable, accelerate and become immediately
    exercisable.
   
(3) During 1997, the Company granted employees options to purchase an
    aggregate of 2,754,560 shares of Common Stock.     
(4) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. The 5% and
    10% assumed annual rates of compounded stock price appreciation are
    mandated by rules of the Securities and Exchange Commission and do not
    represent the Company's estimate or projection of the Company's future
    Common Stock prices. These amounts represent certain assumed rates of
    appreciation in the value of the Company's Common Stock from the exercise
    price of such options (which was in excess of the
 
                                      56

   fair market value of the Common Stock on the date of grant as determined by
   the Company's Board of Directors), as determined by the Company's Board of
   Directors. Actual gains, if any, on stock option exercises are dependent on
   the future performance of the Common Stock and overall stock market
   conditions. The amounts reflected in the table may not necessarily be
   achieved.

  In November 1997, the Company entered into a two-year employment agreement
with Mr. Hansen providing for his employment as Chief Financial Officer of the

The loan to Mr. Evans was made in July 1998 and is payable by Mr. Evans
six months following the consummation of the offering. The loan is unsecured
and would be forgiven upon the achievement by the Company of certain financial
results for 1998. This loan was approved by a majority of the stockholders of

accelerated vesting in his first option and, subject to the Company's
achievement of certain financial results, in his second option as well. In

first anniversary of his employment, other than for cause, the Company must
pay Mr. Evans his base salary for a period of six months and Mr. Evans will
receive credit for one year of accelerated vesting in his first option and,

the Company, or any successor entity, must pay Mr. Barrett his base salary for
a period of six months.

EMPLOYEE BENEFIT PLANS
       
 1998 STOCK INCENTIVE PLAN
   
  In July 1998, the Company adopted the 1998 Stock Incentive Plan (the "1998
Stock Incentive Plan") as the successor equity incentive program to the
Company's 1997 Stock Option Plan (the "Predecessor Plan"). The 1998 Stock
Incentive Plan was adopted by the Board of Directors of the Company and
approved by the stockholders of the Company in July 1998. The Discretionary
Option Grant and Stock Issuance Programs under the 1998 Stock Incentive Plan
became effective immediately upon the Board's adoption of the plan (the "Plan
Effective Date"). The Automatic Option Grant Program will become effective
immediately upon the execution of the Underwriting Agreement for the offering.
    
   
  The Common Stock share reserve of 370,940 shares of Common Stock from the
Predecessor Plan and an additional 2,300,000 shares of Common Stock have been
authorized for issuance under the 1998 Stock Incentive Plan. In no event,
however, may any one participant in the 1998 Stock Incentive Plan receive
option grants, separately exercisable stock appreciation rights or direct
stock issuances for more than 500,000 shares of Common Stock in the aggregate
per calendar year.     
   
  On the date of the execution of the Underwriting Agreement for the offering,
outstanding options granted under the Predecessor Plan will be incorporated
into the 1998 Stock Incentive Plan, and no further option grants will be made
under the Predecessor Plan. The incorporated options will continue to be
governed by their existing terms, however, unless the Plan Administrator
elects to extend one or more features of the 1998 Stock Incentive Plan to
those options. Except as otherwise noted below, the incorporated options have
substantially the same terms as will be in effect for grants made under the
Discretionary Option Grant Program of the 1998 Stock Incentive Plan.     
   
  The 1998 Stock Incentive Plan is divided into five separate components: (i)
the Discretionary Option Grant Program under which eligible individuals in the
Company's employ or service (including officers and consultants) may, at the
discretion of the Plan Administrator, be granted options to purchase shares of
Common Stock at an exercise price equal to not less than the fair market value
of the Common Stock on the date of grant, (ii) the Stock Issuance Program
under which such individuals may, in the Plan Administrator's discretion, be
issued shares of Common Stock directly, through the purchase of such shares at
a price not less than their fair market value at the time of issuance or as a
bonus tied to the performance of services, (iii) the Salary Investment Option
Grant Program which may, in the Plan Administrator's sole discretion, be
activated for one or more calendar years and, if so activated, will allow
executive officers and other highly compensated employees the opportunity to
apply a portion of their base salary to the acquisition of special below-
market stock option grants, (iv) the Automatic Option Grant Program under
which option grants will automatically be made at periodic intervals to
eligible, non-employee members of the Board of Directors to purchase shares of
Common Stock at an exercise price equal to their fair market value on the
grant date and (v) the Director Fee Option Grant Program which may, in the
Plan Administrator's sole discretion, be activated for one or more calendar
years and, if so activated, will allow non-employee Board members the
opportunity to apply a portion of the annual retainer fee otherwise payable to
them in cash each year to the acquisition of special below-market option
grants.     
   
  The Discretionary Option Grant Program and the Stock Issuance Program will
be administered by the Compensation Committee. The Compensation Committee, as
Plan Administrator, will have the discretion to determine which eligible
individuals are to receive option grants or stock issuances under those
programs, the time or times when such option grants or stock issuances are to
be made, the number of shares subject to each such grant or issuance, the
status of any granted option as either an incentive stock option or a non-
statutory stock option under the federal tax laws, the vesting schedule to be
in effect for the option grant or stock issuance and the maximum term for
which any     
 
                                      59
<PAGE>
 
   
granted option is to remain outstanding. The Compensation Committee will also
have the authority to select the executive officers and other highly
compensated employees who may participate in the Salary Investment Option
Grant Program in the event that program is activated for one or more calendar
years, but neither the Compensation Committee nor the Board of Directors will
exercise any administrative discretion with respect to option grants made
under the Salary Investment Option Grant Program or under the Automatic Option
Grant Program or Director Fee Option Grant Program for the non-employee Board
members. All grants under those three latter programs will be made in strict
compliance with the express provisions of each such program.     
   
  The exercise price for the shares of Common Stock subject to option grants
made under the 1998 Stock Incentive Plan may be paid in cash or in shares of
Common Stock valued at fair market value on the exercise date. The option may
also be exercised through a same-day sale program without any cash outlay by
the optionee. In addition, the Plan Administrator may provide financial
assistance to one or more optionees in the exercise of their outstanding
options or the purchase of their unvested shares by allowing such individuals
to deliver a full-recourse, interest-bearing promissory note in payment of the
exercise price and any associated withholding taxes incurred in connection
with such exercise or purchase.     
 
  Stock appreciation rights are authorized for issuance under the
Discretionary Option Grant Program which provide the holders with the election
to surrender their outstanding options for an appreciation distribution from
the Company equal to the excess of (i) the fair market value of the vested
shares of Common Stock subject to the surrendered option over (ii) the
aggregate exercise price payable for such shares. Such appreciation
distribution may be made in cash or in shares of Common Stock. None of the
incorporated options from the Predecessor Plan contain any stock appreciation
rights.
   
  In the event that the Company is acquired by merger or sale of substantially
all of its assets or securities possessing more than 50% of the total combined
voting power of the Company's outstanding securities, each outstanding option
under the Discretionary Option Grant Program which is not to be assumed by the
successor corporation or otherwise continued in effect will automatically
accelerate in full, and all unvested shares under the Discretionary Option
Grant and Stock Issuance Programs will immediately vest, except to the extent
the Company's repurchase rights with respect to those shares are assigned to
the successor corporation or otherwise continued in effect. The Plan
Administrator will have complete discretion to grant one or more options under
the Discretionary Option Grant Program which will become exercisable on an
accelerated basis for all of the option shares upon (i) an acquisition or
other change in control of the Company, whether or not those options are
assumed or continued in effect, or (ii) the termination of the optionee's
service within a designated period (not to exceed 18 months) following an
acquisition or other change in control in which those options are assumed or
continued in effect. The vesting of outstanding shares under the Stock
Issuance Program may be accelerated upon similar terms and conditions. The
Plan Administrator is also authorized under the Discretionary Option Grant and
Stock Issuance Programs to grant options and to structure repurchase rights so
that the shares subject to those options or repurchase rights will immediately
vest in connection with a change in the majority of the Board of Directors of
the Company by reason of one or more contested elections for Board membership,
with such vesting to occur either at the time of such change in control or
upon the subsequent termination of the individual's service within a
designated period following such change in control. Some of the options
incorporated from the Predecessor Plan will also vest on an accelerated basis
under certain circumstances. The Plan Administrator has the discretion to
extend one or more of the other acceleration provisions of the 1998 Stock
Incentive Plan to options incorporated from the Predecessor Plan.     
 
  In the event the Plan Administrator elects to activate the Salary Investment
Option Grant Program for one or more calendar years, each executive officer
and other highly compensated employees of the Company selected for
participation may elect, prior to the start of the calendar year, to reduce
his
 
                                      60
<PAGE>
 
or her base salary for that calendar year by a specified dollar amount not
less than $10,000 nor more than $50,000. If such election is approved by the
Plan Administrator, the individual will automatically be granted, on the first
trading day in January of the calendar year for which that salary reduction is
to be in effect, a non-statutory option to purchase that number of shares of
Common Stock determined by dividing the salary reduction amount by two-thirds
of the fair market value per share of Common Stock on the grant date. The
option will be exercisable at a price per share equal to one-third of the fair
market value of the option shares on the grant date. As a result, the total
spread on the option shares at the time of grant (the fair market value of the
option shares on the grant date less the aggregate exercise price payable for
those shares) will be equal to the amount of salary invested in that option.
The option will become exercisable for the option shares in a series of 12
equal monthly installments over the calendar year for which the salary
reduction is to be in effect and will be subject to full and immediate vesting
upon certain changes in the ownership or control of the Company.
   
  Under the Automatic Option Grant Program, each individual who first becomes
a non-employee Board member at any time after the completion of the offering,
whether by appointment by the Board of Directors or election of the
stockholders, will automatically receive an option grant for 10,000 shares as
of the date such individual joins the Board, provided such individual has not
been in the prior employ of the Company. In addition, on the date of each
Annual Stockholders Meeting of the Company held after the Plan Effective Date,
each non-employee Board member who is to continue to serve as a non-employee
Board member will automatically be granted an option to purchase 2,500 shares
of Common Stock, provided such individual has served on the Board for at least
six months.     
   
  Each automatic grant for the non-employee Board members will have a term of
10 years, subject to earlier termination following the optionee's cessation of
Board service. Each automatic option will be immediately exercisable for all
of the option shares; however, any unvested shares purchased under the option
will be subject to repurchase by the Company, at the exercise price paid per
share, should the optionee cease Board service prior to vesting in those
shares. The shares subject to each initial 10,000-share automatic option grant
will vest over a four-year period in successive equal annual installments upon
the individual's completion of each year of Board service measured from the
option grant date. Each 2,500-share automatic option grant will vest upon the
individual's completion of one year of Board service measured from the option
grant date. However, the shares subject to each automatic grant will
immediately vest in full upon certain changes in control or ownership of the
Company or upon the optionee's death or disability while a Board member.     
   
  Should the Director Fee Option Grant Program be activated in the future,
each non-employee Board member will have the opportunity to apply all or a
portion of any annual retainer fee otherwise payable in cash to the
acquisition of a below-market option grant. The option grant will
automatically be made on the first trading day in January in the year for
which the retainer fee would otherwise be payable in cash. The option will
have an exercise price per share equal to one-third of the fair market value
of the option shares on the grant date, and the number of shares subject to
the option will be determined by dividing the amount of the retainer fee
applied to the program by two-thirds of the fair market value per share of
Common Stock on the grant date. As a result, the total spread on the option
(the fair market value of the option shares on the grant date less the
aggregate exercise price payable for those shares) will be equal to the
portion of the retainer fee invested in that option. The option will become
exercisable for the option shares in a series of 12 equal monthly installments
over the calendar year for which the election is to be in effect. However, the
option will become immediately exercisable for all the option shares upon (i)
certain changes in the ownership or control of the Company or (ii) the death
or disability of the optionee while serving as a Board member.     
   
  The shares subject to each option under the Salary Investment Option Grant
and Automatic Option Grant and Director Fee Option Grant Programs will
immediately vest upon (i) an acquisition of the Company by merger or asset
sale, (ii) the successful completion of a tender offer for more than 50% of
the Company's outstanding voting stock or (iii) a change in the majority of
the Board effected through one or more contested elections for Board
membership.     
 
                                      61
<PAGE>
 
   
  Limited stock appreciation rights will automatically be included as part of
each grant made under the Automatic Option Grant, Salary Investment Option
Grant and Director Fee Option Grant Programs and may be granted to one or more
officers of the Company as part of their option grants under the Discretionary
Option Grant Program. Options with such a limited stock appreciation right may
be surrendered to the Company upon the successful completion of a hostile
tender offer for more than 50% of the Company's outstanding voting stock. In
return for the surrendered option, the optionee will be entitled to a cash
distribution from the Company in an amount per surrendered option share equal
to the excess of (i) the highest price per share of Common Stock paid in
connection with the tender offer over (ii) the exercise price payable for such
share.     
   
  The Board of Directors of the Company may amend or modify the 1998 Stock
Incentive Plan at any time, subject to any required stockholder approval. The
1998 Stock Incentive Plan will terminate on the earliest of (i) 10 years after
the Plan Effective Date, (ii) the date on which all shares available for
issuance under the 1998 Stock Incentive Plan have been issued as fully-vested
shares or (iii) the termination of all outstanding options in connection with
certain changes in control or ownership of the Company.     
   
  The Board of Directors has approved an issuance of shares of Common Stock to
the Company's Community Leaders and Liaisons under the Company's 1998 Stock
Incentive Plan. Immediately following the execution of the Underwriting
Agreement, each of the Company's Community Leaders and Liaisons as of July 17,
1998, will be issued 10 fully vested shares of Common Stock (15,840 in the
aggregate), contingent upon the closing of the offering.     
 
 EMPLOYEE STOCK PURCHASE PLAN
   
  The Company's Employee Stock Purchase Plan (the "Purchase Plan") was adopted
by the Board of Directors and approved by the stockholders of the Company in
July 1998, and will become effective immediately upon the execution of the
Underwriting Agreement for the offering. The Purchase Plan will be designed to
allow eligible employees of the Company and participating subsidiaries to
purchase shares of Common Stock, at semi-annual intervals, through their
periodic payroll deductions under the Purchase Plan, and a reserve of 300,000
shares of Common Stock has been established for this purpose.     
   
  The Purchase Plan will be implemented in a series of successive six-month
purchase periods.The first purchase period will begin on the date the
Underwriting Agreement is executed and will end on the last business day in
January 1999.     
   
  Individuals who are eligible employees (scheduled to work more than 20 hours
per week for more than five calendar months per year) on the start date of any
purchase period may enter the Purchase Plan on that start date or on any
subsequent semi-annual entry date.     
   
  Payroll deductions may not exceed 10% of base salary, and the accumulated
payroll deductions of each participant will be applied to the purchase of
shares on his or her behalf on each semi-annual purchase date at a purchase
price per share equal to 85% of the lower of (i) the fair market value of the
Common Stock on the start date of the purchase period or (ii) the fair market
value on the semi-annual purchase date. In no event, however, may any
participant purchase more than 1,000 shares, nor may all participants in the
aggregate purchase more than 75,000 shares, on any purchase date.     
   
  In the event the Company is acquired by merger or asset sale, all
outstanding purchase rights will automatically be exercised immediately prior
to the effective date of such acquisition. The purchase price will be equal to
85% of the lower of (i) the fair market value per share of Common Stock on the
start date of the purchase period in which such acquisition occurs or (ii) the
fair market value per share of Common Stock immediately prior to such
acquisition.     
 
                                      62
<PAGE>
 
  The Purchase Plan will terminate on the earlier of (i) the last business day
of July 2008, (ii) the date on which all shares available for issuance under
the Purchase Plan shall have been sold pursuant to purchase rights exercised
thereunder or (iii) the date on which all purchase rights are exercised in
connection with an acquisition of the Company by merger or asset sale.
 
  After adoption, the Board may at any time alter, suspend or discontinue the
Purchase Plan. However, certain amendments to the Purchase Plan may require
stockholder approval.
   
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS     
   
  The Certificate provides that, except to the extent prohibited by DGCL, the
Company's directors shall not be personally liable to the Company or its
stockholders for monetary damages for any breach of fiduciary duty as
directors of the Company. Under the DGCL, the directors have a fiduciary duty
to the Company which is not eliminated by this provision of the Certificate
and, in appropriate circumstances, equitable remedies such as injunctive or
other forms of nonmonetary relief will remain available. In addition, each
director will continue to be subject to liability under the DGCL for breach of
the director's duty of loyalty to the Company, for acts or omissions which are
found by a court of competent jurisdiction to be not in good faith or which
involve intentional misconduct, or knowing violations of 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 prohibited
by DGCL. This provision also does not affect the directors' responsibilities
under any other laws, such as the Federal securities laws or state or Federal
environmental laws. The Company has obtained liability insurance for its
officers and directors.     
   
  Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out
of their capacity or status as directors and officers, provided that this
provision shall not eliminate or limit the liability of a director: (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any
other rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate provides that the Company shall, to the fullest extent permitted
by the DGCL, indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or
proceeding (whether civil, criminal, administrative or investigative) by
reason of the fact that such person is or was a director or officer of the
Company, or is or was serving at the request of the Company as a director or
officer of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding.
    
   
  The Company has entered into indemnification agreements with its directors
and certain of its officers containing provisions that may require the
Company, among other things, to indemnify such directors and officers against
certain liabilities that may arise by reason of their status or service as
directors or officers (other than liabilities arising from willful misconduct
of a culpable nature), to advance their expenses incurred as a result of any
proceeding against them as to which they could be indemnified, and to obtain
directors' and officers' liability insurance if maintained for other directors
of officers.     
   
  At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted.

                             CERTAIN TRANSACTIONS
   
  Since January 1, 1995, other than as described elsewhere in this Prospectus
there has not been any transaction or series of similar transactions to which
the Company was or is a party in which the amount involved exceeded or exceeds
$60,000 and in which any director, executive officer, holder of more than 5%
of any class of the Company's voting securities, or any member of the
immediate family of any of the foregoing persons had or will have a direct or
indirect material interest, other than the transactions described below. See
"Management--Employment Agreements and Termination of Employment and Change of
Control Arrangements" and "--Limitation of Liability and Indemnification
Matters".     
 
TRANSACTIONS WITH DIRECTORS, OFFICERS AND 5% STOCKHOLDERS
   
  Since the Company's inception, the Company has raised capital primarily
through the sale of shares of its preferred stock. In December 1995, the
Company issued 1,200,000 shares of Series C Preferred Stock to Mr. Bohnett in
consideration for $0.3217 per share in the form of the cancellation of shares
of Common Stock and a note payable. In January 1996, the Company sold
3,108,000 shares of Series A Preferred Stock to CMG@Ventures at a price of
$0.3218 per share. In July 1996, the Company sold 2,900,000 shares of Series B
Preferred Stock to CMG@Ventures at a price of $0.3793 per share. From January
1997 through February 1997, the Company sold an aggregate of 10,226,718 shares
of Series D Preferred Stock to CMG@Ventures, SOFTBANK Holdings Inc., Chase
Venture Capital Associates, L.P. ("Chase"), the Flatiron Fund, Innocal and
Intel Corporation ("Intel") at a price of $0.885 per share. In October 1997,
the Company sold an aggregate of 1,428,564 shares of Series E Preferred Stock
to CMG@Ventures II, LLC, SOFTBANK Holdings Inc., the Flatiron Fund, Innocal
and Intel at a price of $3.50 per share. In December 1997, the Company sold an
aggregate of 814,270 shares of Series E Preferred Stock to SOFTBANK Holdings
Inc. at a price of $7.4254 per share. Effective December 1997, the Company
sold an aggregate of 2,552,576 shares of Series F Preferred Stock to Yahoo!
and SOFTBANK Holdings Inc. at a price of $7.4254 per share.     
   
  The following table summarizes the shares of Common Stock and Preferred
Stock purchased by executive officers, directors, and 5% stockholders of the
Company and persons associated with them since January 1995. All share numbers
reflect the number of shares of Common Stock purchased by the respective party
on an as-converted basis, and reflects subsequent sales of preferred stock and
transfers of Common Stock among stockholders of the Company and among
stockholders and the Company.

  The Company entered into a Joint Venture Agreement in November 1997 (the
"Joint Venture Agreement") with SOFTBANK to form GeoCities Japan, a joint
venture in Japan. SOFTBANK, which owns 60% of GeoCities Japan, is a greater
than five percent stockholder in the Company. Under the terms of the
agreement, the Company purchased a 40% interest in GeoCities Japan for (Yen)80
million or approximately $645,000. SOFTBANK and the Company further agreed not
to engage in any business activities in Japan, other than services or products
in languages other than Japanese, which compete with GeoCities Japan. In
connection with this agreement, the Company agreed to enter into a 20-year
licensing agreement with GeoCities Japan under which the Company is eligible
to receive royalties. In connection with the Joint Venture Agreement, the
Company has entered into a Loan Agreement with SOFTBANK, whereby SOFTBANK
loaned the Company (Yen)80 million or approximately $645,000 for the sole
purpose of purchasing its 40% interest in GeoCities Japan. The loan bears
interest of 5.5% each year and shall be repaid upon GeoCities Japan's non-U.S.
initial public offering or private placement of at least (Yen)1.5 billion. If
neither event occurs by March 31, 2000, then SOFTBANK will forgive the loan on
April 1, 2000. See "Management's Discussion and Analysis of Financial
Conditions and Results of Operations" and Note 5 of Notes to Financial
Statements.
 
  The Company's 20-year license agreement with GeoCities Japan, entered in
November 1997, grants GeoCities Japan the exclusive right to use the Company's
software, content and trademarks (collectively, the "Materials") to provide
services in Japan. The Company also grants GeoCities Japan a license to
translate the Materials into the Japanese language. In consideration of the

                         DESCRIPTION OF CAPITAL STOCK
 
  The following description of the securities of the Company and certain
provisions of the Company's Certificate of Incorporation (the "Certificate")
and the Company's Bylaws ("Bylaws") are summaries thereof and are qualified by
reference to the Certificate and the Bylaws, copies of which have been filed
with the Commission as exhibits to the Company's Registration Statement, of
which this Prospectus forms a part. The descriptions of the Common Stock and
Preferred Stock reflect changes to the Company's capital structure that will
occur upon the closing of the offering in accordance with the terms of the
Certificate.
   
  The authorized capital stock of the Company consists of 60,000,000 shares of
Common Stock, par value $0.001 per share and 5,000,000 shares of Preferred
Stock, par value $0.001 per share.     
 
COMMON STOCK
   
  As of June 30, 1998, there were 25,895,000 shares of Common Stock
outstanding (on an as-converted basis) and held of record by 29 stockholders.
Based upon the number of shares outstanding as of that date and giving effect
to the issuance of the 4,750,000 shares of Common Stock offered by the Company
hereby and the issuance of 15,840 shares of Common Stock to be issued to
Community Leaders and Liaisons under the 1998 Stock Incentive Plan, there will
be 30,660,840 shares of Common Stock outstanding (on an as-converted basis)
upon the closing of the offering.     
   
  Holders of Common Stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and the Certificate provides that
they do not have cumulative voting rights. Accordingly, holders of a majority
of the shares of Common Stock entitled to vote in any election of directors
may elect all of the directors standing for election. Holders of Common Stock
are entitled to receive ratably such dividends, if any, as may be declared by
the Board of Directors out of funds legally available therefor, subject to any
preferential dividend rights of any outstanding Preferred Stock. Upon the
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to receive ratably the net assets of the Company available
after the payment of all debts and other liabilities and subject to the prior
rights of any outstanding Preferred Stock. Holders of the Common Stock have no
preemptive, subscription, redemption or conversion rights. The outstanding
shares of Common Stock are, and the shares offered by the Company in the
offering will be, when issued in consideration for payment thereof, fully paid
and nonassessable. The rights, preferences and privileges of holders of Common
Stock are subject to, and may be adversely affected by, the rights of the
holders of shares of any series of Preferred Stock which the Company may
designate and issue in the future without further stockholder approval. Upon
the closing of the offering, there will be no shares of Preferred Stock
outstanding.     
 
PREFERRED STOCK
 
  Upon the closing of the offering, the Board of Directors will be authorized,
without further stockholder approval, to issue from time to time up to an
aggregate of 5,000,000 shares of Preferred Stock in one or more series and to
fix or alter the designations, preferences, rights and any qualifications,
limitations or restrictions of the shares of each such series thereof,
including the dividend rights, dividend rates, conversion rights, voting
rights, terms of redemption (including sinking fund provisions), redemption
price or prices, liquidation preferences and the number of shares constituting
any series or designations of such series. The Company has no present plans to
issue any shares of Preferred Stock. See "--Anti-Takeover Effects of Certain
Provisions of Delaware Law and the Company's Certificate of Incorporation and
Bylaws".
 
WARRANTS
   
  As of June 30, 1998, the Company had an outstanding warrant to purchase
20,304 shares of Common Stock at an exercise price of $4.695 per share. The
warrant is exercisable in whole or in part at any time on or before September
22, 2004. The warrant contains standard anti-dilution provisions,     
 
                                      69
<PAGE>
 
including anti-dilution protection if the Company issues any shares of Common
Stock at a price per share less than the exercise price of such warrant at the
time in effect or without consideration, subject to certain exceptions.
 
OPTIONS
   
  As of June 30, 1998, (i) options to purchase a total of 6,531,000 shares
("Option Shares") of Common Stock were outstanding and (ii) up to 797,000
shares of Common Stock were available for grant under the Predecessor Plan.
See "Underwriting" and "Management--Employee Benefit Plans".     
   
TECHNOLOGY PURCHASE AND SALE AGREEMENT     
   
  In July 1998, the Company entered into a Technology Purchase and Sale
Agreement (the "Purchase Agreement") pursuant to which the Company purchased
certain Web-page development technology (the "Technology"). Under the terms of
the Purchase Agreement, in partial consideration for the Technology, the
Company agreed to issue $455,000 of its Common Stock to the seller at the
initial public offering price (assuming the offering is consummated within 90
days of the date of the Purchase Agreement; otherwise, the Company is
obligated to pay this amount in cash), if the Technology is successfully
installed and becomes operational on the Company's servers to the Company's
satisfaction within 90 days of the date of the Purchase Agreement, In
addition, if the Technology is successfully installed and is operational
within an agreed upon period prior to the 90-day deadline, the Company has
agreed to issue the seller an additional $145,000 of its Common Stock at the
initial public offering price. Any shares of the Company's Common Stock issued
under the provisions of the Purchase Agreement are subject to the restrictions
on resale imposed by Rule 144 under the Securities Act. The seller has also
entered into a lock-up agreement prohibiting any sales or transfers of such
shares for a period of 180 days after the date of this Prospectus without the
prior written consent of Goldman, Sachs & Co.     
 
REGISTRATION RIGHTS
   
  Pursuant to the terms of the Third Amended and Restated Rights Agreement, as
amended (the "Registration Rights Agreement"), after the closing of the
offering, the holders of at least 30% of an aggregate of 22,230,128 shares of
Common Stock will be entitled to certain demand registration rights with
respect to the registration of such shares under the Securities Act, subject
to certain limitations, including the inclusion thereon of a minimum number of
shares held by the initiating holders of the demand registration. The Company
is not required to effect (i) more than two such registrations pursuant to
such demand registration rights; (ii) a registration within 90 days following
the determination of the Board of Directors of the Company to file a
registration statement; provided, that the Company is making a good faith
effort to cause such registration statement to become effective; (iii) a
registration for a period not to exceed 90 days, if the Board of Directors of
the Company has made a good faith determination that it would be seriously
detrimental to the Company or the holders of registration rights for a
registration statement to be filed or (iv) a registration within 270 days of
the effective date of any prior registered offering of the Company's
securities, subject to certain exceptions. In addition, pursuant to the terms
of the Registration Rights Agreement, after the closing of the offering, the
holders of 26,140,128 shares of Common Stock will be entitled to certain
piggyback registration rights in connection with any registration by the
Company of its securities for its own account or the account of other
securityholders. In the event that the Company proposes to register any shares
of Common Stock under the Securities Act, the holders of such piggyback
registration rights are entitled to receive notice of such registration and
are entitled to include their shares therein, subject to certain limitations.
In addition, in the event that the Company proposes to register any shares of
Common     
 
                                      70
<PAGE>
 
   
Stock under the Securities Act to the public in a firm commitment underwritten
public offering, Mr. Bohnett and Mr. Rezner, as well as any other officer or
director designated by the Company's Board of Directors by unanimous vote
shall be entitled to piggyback registration rights if such persons who choose
to include their shares in such registration shall continue to serve the
Company as an officer or director on the effective date of such registration
statement. Further, at any time after the Company becomes eligible to file a
registration statement on Form S-3, certain holders of demand registration
rights may require the Company to file registration statements on Form S-3
under the Securities Act with respect to their shares of Common Stock. The
Company is not required to effect (i) more than two such registrations in any
12-month period; (ii) a registration if the Company gives notice of its bona
fide intention to effect a registration within 60 days; (iii) a registration
within 180 days of the effective date of any prior registered offering of the
Company's securities (subject to certain exceptions) or (iv) a registration
for a period not to exceed 60 days, if the Board of Directors of the Company
has made a good faith determination that it would be seriously detrimental to
the Company or the stockholders for a registration statement to be filed
(subject to certain exceptions). Each of the foregoing registration rights are
subject to certain conditions and limitations, among them the right of the
underwriters in any underwritten offering to limit the number of shares of
Common Stock held by securityholders with registration rights to be included
in such registration. The registration rights with respect to any holder
thereof terminate when the shares held by such holder may be sold under Rule
144 during any three-month period. The Company is generally required to bear
all of the expenses of all such registrations, except underwriting discounts
and commissions. Registration of any of the shares of Common Stock held by
securityholders with registration rights would result in such shares becoming
freely tradable without restriction under the Securities Act immediately upon
effectiveness of such registration. The Registration Rights Agreement also
contains a commitment of the Company to indemnify the holders of registration
rights, subject to certain limitations.     
 
ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF DELAWARE LAW AND THE COMPANY'S
CERTIFICATE OF INCORPORATION AND BYLAWS
   
  The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law (as amended from time to time, the "DGCL"). Subject to
certain exceptions, Section 203 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 of the transaction in which the person
became an interested stockholder, unless the interested stockholder attained
such status with the approval of the board of directors or unless the business
combination is approved in a prescribed manner. A "business combination"
includes mergers, asset sales and other transactions resulting in a financial
benefit to the interested stockholder. Subject to certain exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, 15% or more of the
corporation's outstanding voting stock. This statute could prohibit or delay
the accomplishment of mergers or other takeover or change in control attempts
with respect to the Company and, accordingly, may discourage attempts to
acquire the Company.     
 
  In addition, certain provisions of the Certificate and Bylaws, which
provisions will be in effect upon the closing of the offering and are
summarized in the following paragraphs, may be deemed to have an anti-takeover
effect and may delay, defer or prevent a tender offer or takeover attempt that
a stockholder might consider in its best interest, including those attempts
that might result in a premium over the market price for the shares held by
stockholders.
 
  STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS. The Certificate
provides that stockholders may not take action by written consent, but only at
duly called annual or special meetings of stockholders. The Certificate
further provides that special meetings of stockholders of the Company may be
called only by the Chairman of the Board of Directors or a majority of the
Board of Directors.
 
                                      71
<PAGE>
 
  ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR
NOMINATIONS. The Bylaws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for
election as directors at an annual meeting of stockholders, must provide
timely notice thereof in writing. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
Company, not less than 120 days nor more than 150 days prior to the first
anniversary of the date of the Company's notice of annual meeting provided
with respect to the previous year's annual meeting of stockholders; provided,
that if no annual meeting of stockholders was held in the previous year or the
date of the annual meeting of stockholders has been changed to be more than 30
calendar days earlier than or 60 calendar days after such anniversary, notice
by the stockholder, to be timely, must be so received not more than 90 days
nor later than the later of (i) 60 days prior to the annual meeting of
stockholders or (ii) the close of business on the 10th day following the date
on which notice of the date of the meeting is given to stockholders or made
public, whichever first occurs. The Bylaws also specify certain requirements
as to the form and content of a stockholder's notice. These provisions may
preclude stockholders from bringing matters before an annual meeting of
stockholders or from making nominations for directors at an annual meeting of
stockholders.
 
  AUTHORIZED BUT UNISSUED SHARES. The authorized but unissued shares of Common
Stock and Preferred Stock are available for future issuance without
stockholder approval. These additional shares may be utilized for a variety of
corporate purposes, including future public offerings to raise additional
capital, corporate acquisitions and employee benefit plans. The existence of
authorized but unissued shares of Common Stock and Preferred Stock could
render more difficult or discourage an attempt to obtain control of the
Company by means of a proxy contest, tender offer, merger or otherwise.
 
  The DGCL provides generally that the affirmative vote of a majority of the
shares entitled to vote on any matter is required to amend a corporation's
certificate of incorporation or bylaws, unless a corporation's certificate of
incorporation or bylaws, as the case may be, requires a greater percentage.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to the offering, there has been no public market for the Common Stock
of the Company. Future sales of substantial amounts of Common Stock in the
public market could adversely affect prevailing market prices from time to
time. Furthermore, since only a limited number of shares will be available for
sale shortly after the offering because of certain contractual and legal
restrictions on resale (as described below), sales of substantial amounts of
Common Stock of the Company in the public market after the restrictions lapse
could adversely affect the prevailing market price of the Common Stock and the
ability of the Company to raise equity capital in the future.
   
  Upon completion of the offering, the Company will have outstanding an
aggregate of 30,660,840 shares of Common Stock, assuming no exercise of the
Underwriters' over-allotment option. Of these shares, the 4,750,000 shares
registered in the offering will be freely tradeable without restriction or
further registration under the Securities Act, unless such shares are
purchased by "Affiliates". The 15,840 shares of Common Stock to be issued to
the Community Leaders and Liaisons under the 1998 Stock Incentive Plan will
also be eligible for immediate sale in the public market without restriction,
subject to the filing of the Form S-8 registration statement with respect
thereto as of the date of this Prospectus. The 25,895,000 shares of Common
Stock outstanding as of June 30, 1998, and held by existing stockholders are
"restricted securities" as that term is defined in Rule 144 under the
Securities Act ("Restricted Shares"). Restricted Shares may be sold in the
public market only if registered or if they qualify for an exemption from
registration under Section 4(1) of the Securities Act or Rules 144, 144(k) or
701 promulgated under the Securities Act, which rules are summarized below. As
a result of the lock-up agreements described below, and subject to the
provisions of Rules 144, 144(k) and 701, the 25,895,000 shares which are
deemed Restricted Shares will be available for sale in the public market 180
days after the date of this Prospectus. Any shares of Common Stock issued
pursuant to the Purchase Agreement will be restricted securities and will also
be subject to a 180 day lock-up agreement. In addition, as of June 30, 1998,
there were outstanding options to purchase up to 6,531,000 shares of Common
Stock which will be eligible for sale in the public market following the
offering from time to time subject to becoming exercisable and, in the case of
certain options, the expiration of the lock-up agreements. There is also a
warrant outstanding to purchase up to 20,304 shares of Common Stock which will
be eligible for sale in the public market following the offering subject to
the expiration of the lock-up agreement applicable thereto.     
   
  All officers and directors, and substantially all other stockholders and
holders of options to purchase Common Stock of the Company have agreed not to
sell or otherwise transfer any shares of Common Stock or any other securities
of the Company for a period of 180 days after the date of this Prospectus
without the prior written consent of Goldman, Sachs & Co.; provided, that one
affiliate of the Company who is subject to a lock-up agreement and the volume
restrictions of Rule 144 has been authorized by the representatives of the
Underwriters to sell up to $1.0 million of Common Stock commencing 91 days
after the date of this Prospectus. In addition, Goldman, Sachs & Co. may, in
their sole discretion, and at any time without notice, release all or any
portion of the securities subject to lock-up agreements.     
   
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned Restricted Shares for
at least one year (including the holding period of any prior owner except an
Affiliate) would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of: (i) one percent of the number of
shares of Common Stock then outstanding (which will equal approximately
307,000 shares immediately after the offering) or (ii) the average weekly
trading volume of the Common Stock on the Nasdaq National Market during the
four calendar weeks preceding the filing of a notice on Form 144 with respect
to such 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 the Company. Under Rule 144(k), a person who is not deemed
to have been an Affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares proposed to be
sold for at least     
 
                                      73
<PAGE>
 
two years (including the holding period of any prior owner except an
Affiliate), is entitled to sell such shares without complying with the manner
of sale, public information, volume limitation or notice provisions of Rule
144; therefore, unless otherwise restricted, and subject to the lock-up
agreements, "144(k) shares" may be sold immediately upon the completion of the
offering. In general, under Rule 701 of the Securities Act as currently in
effect, any employee, consultant or advisor of the Company who purchases
shares from the Company pursuant to Rule 701 in connection with a compensatory
stock or option plan or other written agreement is eligible to resell such
shares, unless contractually restricted, 90 days after the effective date of
the offering in reliance on Rule 144, but without compliance with certain
restrictions, including the holding period, contained in Rule 144.
 
  The Company is unable to estimate the number of shares that will be sold
under Rule 144, as this will depend on the market price for the Common Stock
of the Company, the personal circumstances of the sellers and other factors.
Prior to the offering, there has been no public market for the Common Stock,
and there can be no assurance that a significant public market for the Common
Stock will develop or be sustained after the offering. Any future sale of
substantial amounts of Common Stock in the open market may adversely affect
the market price of the Common Stock offered hereby.
   
   The Company intends to file, as of the date of this Prospectus, Form S-8
registration statements under the Securities Act to register all shares of
Common Stock issuable under certain individual stock option agreements and the
1998 Stock Incentive Plan, the shares of Common Stock that will be issued to
the Community Leaders and Liaisons thereunder immediately following the
execution of the Underwriting Agreement and shares of Common Stock issuable
under the Purchase Plan. Such registration statements are expected to become
effective immediately upon filing, and shares covered by those registration
statements will thereupon be eligible for sale in the public markets, subject
to any lock-up agreements applicable thereto and Rule 144 limitations
applicable to affiliates. See "Management--Employee Benefit Plans",
"Description of Capital Stock--Registration Rights", "Shares Eligible for
Future Sale" and "Underwriting".     
   
  Pursuant to the Registration Rights Agreement, after the closing of the
offering, subject to certain conditions, the holders of 22,230,128 shares of
outstanding Common Stock will be entitled to certain demand registration
rights and the holders of 26,140,128 shares of outstanding Common Stock
(including shares issuable upon the exercise of certain options to purchase
Common Stock) will be entitled to certain piggyback registration rights.
Registration of such shares under the Securities Act would result in such
shares becoming freely tradeable without restriction under the Securities Act
(except for shares purchased by Affiliates). During the 180-day period after
the date of this Prospectus, the Company has agreed not to file any
registration statement with respect to the registration of any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
into Common Stock, other than registration statements on Form S-8 covering
securities issuable under the Company's 1998 Stock Incentive Plan and the
Purchase Plan, without the prior written consent of Goldman, Sachs & Co. See
"Description of Capital Stock--Registration Rights".     
 
                                 LEGAL MATTERS
 
  The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Brobeck, Phleger & Harrison LLP, Irvine, California.
Certain legal matters relating to the offering will be passed upon for the
Underwriters by Venture Law Group, A Professional Corporation, Menlo Park,
California.

  The Company intends to furnish to its stockholders annual reports containing
financial statements audited by its independent auditors and to make available
to its stockholders quarterly reports containing unaudited financial data for
the first three quarters of each fiscal year.
 
                             CHANGE IN ACCOUNTANTS
   
  On September 18, 1997, the Company requested and received the resignation of
Arthur Andersen LLP and engaged PricewaterhouseCoopers LLP as its independent
accountants to audit its financial statements as of, and for the year ended,
July 31, 1997. The decision to change independent accountants from Arthur
Andersen LLP to PricewaterhouseCoopers LLP was approved by the Company's Board
of Directors. Subsequently, the Company changed its fiscal year end from July
31 to December 31.     
 
  The Company believes, and has been advised by Arthur Andersen LLP that it
concurs in such belief, that, for the period from December 16, 1994
(inception) through July 31, 1996, and for the period from August 1, 1996
through September 18, 1997, the Company and Arthur Andersen LLP did not have
any disagreement on any matter of accounting principles or practices,
financial statement disclosure or auditing scope or procedure, which
disagreement, if not resolved to the satisfaction of Arthur Andersen LLP,
would have caused it to make reference in connection with its report on the
Company's financial statements to the subject matter of the disagreement.
 
  The report of Arthur Andersen LLP on the Company's financial statements for
the period from December 16, 1994 (inception) through July 31, 1995, and the
year ended July 31, 1996, did not contain an adverse opinion or a disclaimer
of opinion, and was not qualified or modified as to uncertainty, audit scope
or accounting principles. During the period from December 16, 1994 to
September 18, 1997, there were no "reportable events" within the meaning of
Item 304(a)(1)(v) of Regulation S-K promulgated under the Securities Act.

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

1.  ORGANIZATION AND BUSINESS:     
 
  GeoCities (the "Company") was incorporated as a California corporation on
December 16, 1994, and began operations in 1995. In June 1998, the Board of
Directors approved the reincorporation of the Company in the State of Delaware
and changed the par value of the Company's common stock. The Company offers a
community of personal Web sites on the Internet within 40 themed
neighborhoods. The Company's main source of revenue is from advertising, along
with other revenue streams, including fee-based premium services and commerce.
The Company's business is characterized by rapid technological change, new
product development and evolving industry standards.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Initial Public Offering and Unaudited Pro Forma Balance Sheet
   
  In June 1998, 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 Mandatory Redeemable
Convertible Preferred Stock will automatically convert into shares of common
stock on a one-for-one basis. The conversion of the Mandatory Redeemable
Convertible Preferred Stock has been reflected in the accompanying unaudited
pro forma balance sheet as if it had occurred on June 30, 1998.     
 
 Unaudited Interim Financial Information
   
  The interim financial statements of the Company for the six months ended
June 30, 1997 and 1998, included herein have been prepared by the Company,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to such
rules and regulations relating to interim financial statements. In the opinion
of management, the accompanying unaudited interim financial statements reflect
all adjustments, consisting only of normal recurring adjustments, necessary to
present fairly the financial position of the Company at June 30, 1998, and the
results of its operations and its cash flows for the six months ended June 30,
1997 and 1998.     
 
 Use of Estimates
 
  In the normal course of preparing financial statements in conformity with
generally accepted accounting principles, management is required 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 could differ from those estimates.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.
 
  At December 31, 1997, certificates of deposit totaling approximately
$255,000 were used to collateralize certain of the Company's lease
obligations, and have been included in deposits on the balance sheet.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
     
  (ALL INFORMATION WITH RESPECT TO JUNE 30, 1998 AND 1997 IS UNAUDITED)     
 
 
 Investments
   
  Investments consist of debt securities, primarily U.S. government and
corporate debt securities. These investments are stated at cost as it is the
intent of the Company to hold these securities until maturity. The investments
are recorded at their amortized cost on the balance sheet which approximates
fair value. The unamortized discount on investments is approximately $348,000
at June 30, 1998.     
 
 Property and Equipment
 
  Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is computed using the straight-line method based
upon the estimated useful lives of the assets, ranging from three to five
years. Leasehold improvements and equipment under capital leases are amortized
over the shorter of the estimated useful life or the life of the lease. Useful
lives are evaluated regularly by management in order to determine
recoverability in light of current technological conditions. Maintenance and
repairs are charged to expense as incurred while renewals and improvements are
capitalized. Upon the sale or retirement of property and equipment, the
accounts are relieved of the cost and the related accumulated depreciation or
amortization, with any resulting gain or loss included in the Statement of
Operations.
 
 Long-lived Assets
 
  The Company identifies and records impairment losses on long-lived assets
when events and circumstances indicate that such assets might be impaired. To
date, no such impairment has been recorded.
 
 Computation of Historical Net Loss Per Share and Pro Forma Net Loss Per Share
 
  The Company adopted SFAS No. 128, "Computation of Earnings Per Share",
during the year ended December 31, 1997. In accordance with SFAS No. 128,
basic earnings per share is computed using the weighted average number of
common and dilutive common equivalent shares outstanding during the period.
Common equivalent shares consist of the incremental common shares issuable
upon the conversion of the Mandatory Redeemable Convertible Preferred Stock
(using the if-converted method) and shares issuable upon the exercise of stock
options and warrants (using the Treasury Stock method); common equivalent
shares are excluded from the calculation if their effect is anti-dilutive.
Pursuant to SEC Staff Accounting Bulletin No. 98, common stock and convertible
preferred stock issued for nominal consideration, prior to the anticipated
effective date of an IPO, are required to be included in the calculation of
basic and diluted net loss per share, as if they were outstanding for all
periods presented. To date, the Company has not had any issuances or grants
for nominal consideration.
   
  Diluted net loss per share for the years ended December 31, 1995, 1996 and
1997, and the six months ended June 30, 1998, does not include the effect of
options to purchase 777,000, 1,113,000, 4,605,000 and 6,531,000 shares of
common stock, respectively, 0, 0, 20,304 and 20,304 common stock warrants,
respectively, or 0, 6,008,000, 22,230,000 and 22,230,000 shares of Mandatory
Redeemable Convertible Preferred Stock on an "as if converted" basis,
respectively, as the effect of their inclusion is antidilutive during each
period.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
     
  (ALL INFORMATION WITH RESPECT TO JUNE 30, 1998 AND 1997 IS UNAUDITED)     
   
  Pro forma net loss per share for the year ended December 31, 1997 and for
the six months ended June 30, 1998, assumes that the common stock issuable
upon conversion of the outstanding Mandatory Redeemable Convertible Preferred
Stock had been outstanding during each such period.     
 
 Stock-based Compensation
 
  The Company accounts for stock-based employee compensation arrangements in
accordance with the provisions of Accounting Principles Board ("APB") No. 25,
"Accounting for Stock Issued to Employees," and complies with the disclosure
requirements of SFAS No. 123, "Accounting for Stock-Based Compensation." Under
APB No. 25, compensation cost, if any, is recognized over the respective
vesting period based on the difference, on the date of grant, between the fair
value of the Company's common stock and the grant price.
 
 Income Taxes
 
  The Company utilizes the liability method of accounting for income taxes.
Under this method, deferred tax liabilities and assets are determined based on
the difference between the financial statement and the tax bases of assets and
liabilities using enacted tax rates in effect for the period in which the
differences are expected to reverse. Valuation allowances are established,
when necessary, to reduce deferred tax assets to the amount expected to be
realized.
 
 Revenue Recognition
 
  The Company's revenues are derived principally from the sale of banner
advertisements under short-term contracts; advertising rates are dependent on
whether the impressions are for general rotation throughout the Company's Web
site or premier targeted audiences and properties within specific areas of the
Company's Web site. To date, the duration of the Company's advertising
commitments has generally averaged from one to two months. In December 1997,
the Company also began selling a combination of sponsorship and banner
advertising campaign contracts to select premier commerce partners. In
general, these premier commerce partner contracts have longer terms than
standard banner advertising contracts (generally up to one year) and involve
some integration with the Company's Web site. Advertising revenues on both
banner and premier commerce partner contracts are recognized ratably in the
period in which the advertisement is displayed, provided that no significant
Company obligations remain and collection of the resulting receivable is
probable. Company obligations typically include the guarantee of a minimum
number of "impressions" or times that an advertisement appears in pages viewed
by the users of the Company's online properties.
   
  In addition to advertising revenues, the Company derives revenues from its
GeoPlus program, a premium service for its members (introduced in late 1996)
and GeoShops, a commerce service for its members (introduced in March 1998).
These services require the payment of monthly fees by the customers; revenues
are recognized on a monthly basis as the fees become due. GeoPlus revenues
accounted for 4%, 7% and 9% of revenues for the years ended December 31, 1996
and 1997, and the six months ended June 30, 1998, respectively; to date, the
revenues from GeoShops have been immaterial. The Company also has revenue
sharing agreements with its premier commerce partners. These revenues are
recognized by the Company upon notification by the premier commerce partners
of revenues earned by the Company, and to date, have been immaterial.     
 
 
  Barter transactions are recorded at the lower of estimated fair value of the
goods or services received or the estimated fair value of the advertisements
given. To date, barter transactions have been immaterial.

  (ALL INFORMATION WITH RESPECT TO JUNE 30, 1998 AND 1997 IS UNAUDITED)     
 
 
 Advertising
   
  Advertising costs are expensed as incurred, and amounted to approximately
$66,000, $196,000 and $1,742,000 for the years ended December 31, 1995, 1996
and 1997, respectively, and $386,000 for the six months ended June 30, 1998.
    
 Product Development
       
   
  Product development costs are expensed as incurred. Statement of Financial
Accounting Standards No. 86, "Accounting for the Costs of Computer Software to
be Sold, Leased or Otherwise Marketed," requires capitalization of certain
software development costs subsequent to the establishment of technological
feasibility. Based upon the Company's product development process,
technological feasibility is established upon completion of a working model.
Costs incurred by the Company between completion of the working model and the
point at which the product is ready for general release have been
insignificant.     
 
 Recent Accounting Pronouncements
   
  In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." This statement establishes standards for the reporting and display of
comprehensive income and its components in a full set of general purpose
financial statements. Comprehensive income generally represents all changes in
shareholders' equity during the period except those resulting from investments
by, or distributions to, shareholders. SFAS No. 130 is effective for fiscal
years beginning after December 15, 1997 and requires restatement of earlier
periods presented. SFAS No. 130 had no impact on the Company's financial
statements.     
 
  In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information." SFAS No. 131 establishes standards for
the way that a public enterprise reports information about operating segments
in annual financial statements, and requires that those enterprises report
selected information about operating segments in interim financial reports
issued to shareholders. SFAS No. 131 is effective for fiscal years beginning
after December 15, 1997 and requires restatement of earlier periods presented.
Management is currently evaluating the requirements of SFAS No. 131.
 
 Stock Split
   
  In January 1996, September 1997 and July 1998, the Company authorized and
implemented 1,443-for-one, two-for-one and two-for-one stock splits,
respectively. The share information in the accompanying financial statements
has been retroactively restated to reflect the effect of these stock splits.
    
3.  CONCENTRATION OF CREDIT RISK:
 
  Financial instruments which subject the Company to concentrations of credit
risk consist primarily of cash and cash equivalents, short-term investments
and trade accounts receivable. The Company maintains cash and cash equivalents
with various domestic financial institutions. The Company performs periodic
evaluations of the relative credit standing of these institutions. From time
to time, the Company's cash balances with any one financial institution may
exceed Federal Deposit Insurance Corporation insurance limits.

  (ALL INFORMATION WITH RESPECT TO JUNE 30, 1998 AND 1997 IS UNAUDITED)     
 
  The Company's customers are concentrated in the United States. The Company
performs ongoing credit evaluations, generally does not require collateral and
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of customers, historical trends and other information; to
date, such losses have been within management's expectations.
 
  For the year ended December 31, 1996, two customers accounted for
approximately 14% and 10%, respectively, of all revenues generated by the
Company and 18% and 0%, respectively, of accounts receivable at December 31,
1996.
 
  For the year ended December 31, 1997, one customer accounted for 12% of all
revenues generated by the Company, and 12% of accounts receivable at December
31, 1997.
   
  For the six months ended June 30, 1998, one customer accounted for 10% of
all revenues generated by the Company and 3% of accounts receivable at June
30, 1998.

5.  RELATED-PARTY TRANSACTIONS:
 
  On November 6, 1997, the Company and SOFTBANK Corporation of Japan
("SOFTBANK"), the parent company of an investor in the Company, formed a joint
venture called GeoCities Japan Corporation ("GeoCities Japan") to create and
manage a Japanese version of GeoCities. In accordance with the joint venture
agreement ("Agreement"), the Company purchased 40% of GeoCities Japan for
approximately $645,000 and licensed certain intellectual properties for the
purpose of localizing the Japanese version of GeoCities to GeoCities Japan.
The Agreement remains in effect perpetually, provided that, if as of April 1,
2001, or any April 1 thereafter; (i) GeoCities Japan has sustained net losses
for the four consecutive fiscal quarters, and (ii) GeoCities and SOFTBANK
differ with respect to the future business plan of GeoCities Japan, then each
party shall have the right to terminate the Joint Venture with 90-days notice.
 
                                     F-11

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
     
  (ALL INFORMATION WITH RESPECT TO JUNE 30, 1998 AND 1997 IS UNAUDITED)     
 
 
  The Company's investment of approximately $645,000 was funded through a loan
from SOFTBANK. Pursuant to the terms of the loan agreement, the loan bears
interest at 5.5% per annum and is repayable upon occurrence of a Significant
Financing Event, which is defined as a non-U.S. IPO or private placement that
raises at least 1.5 billion yen for GeoCities Japan. In the event that
GeoCities Japan does not have a Significant Financing Event on or prior to
March 31, 2000, SOFTBANK will forgive the repayment of the loan. Interest
expense and accrued interest for the year ended December 31, 1997, were each
$6,000.
 
  In consideration of the licenses granted, GeoCities Japan is required to pay
the Company an amount equal to 3% of total revenue obtained by GeoCities Japan
within 30 days of the end of each quarter. The license expires 20 years from
the date of the Agreement, unless the Agreement is terminated earlier. Upon
termination, GeoCities Japan will cease to use and distribute all licensed
properties. Royalty payments for the year ended December 31, 1997, were
insignificant.
   
  The investment is being accounted for under the equity method and is
included in other assets at December 31, 1997. The loss on affiliate recorded
for the six months ended June 30, 1998, was approximately $86,000.     
   
  Advertising revenues at December 31, 1997 and June 30, 1998, include
$107,000 and $51,000, respectively, in revenues received from an entity that
is controlled by a significant shareholder of the Company. At December 31,
1997 and June 30, 1998, $0 and $35,000, respectively, of these amounts are
included in accounts receivable.     
 
  In April 1998, the Board of Directors also approved a loan of $100,000 to an
officer/director of the Company.
   
  In December 1997, in conjunction with its financing activities, the Company
entered into a one-year distribution and commerce agreement ("Agreement") with
Yahoo!, which is automatically renewable for subsequent one-year terms,
subject to the right of either party to terminate the relationship at the end
of any term up to 90-days' notice. In connection with the Agreement, Yahoo!
also made a minority equity investment in the Company. The Agreement was
designed to increase traffic and memberships of both parties in addition to
offering GeoCities' Homesteaders an array of free personalized member services
on Yahoo!. Under the terms of the Agreement, GeoCities agreed to provide its
community-based, Web site and other services for free to registered users of
Yahoo!. In addition, Yahoo! agreed to market GeoCities-branded personal
publishing programs on select areas throughout Yahoo!, as well as provide a
GeoCities-specific programming module on My Yahoo! for GeoCities'
Homesteaders. The Agreement did not involve any cash consideration; any
revenues related to the Agreement will be accounted for in accordance with the
Company's barter revenue recognition policy, as appropriate.     
 
6.  LINE OF CREDIT:
   
  In August 1997, the Company executed a $2,000,000 revolving line of credit
(the "Line") with a commercial bank. Pursuant to the agreement, the Line
matures on December 1, 1998, bears interest at the bank's prime rate of
interest, plus 0.50% (8.5% at December 31, 1997), and is collateralized by
substantially all of the Company's assets. The Company is required to comply
with certain financial covenants, as defined in the agreement, which include
tangible effective net-worth and quick-ratio agreements. In connection with
the Line, the Company issued a warrant to the bank to purchase up to 20,304
shares of the Company's common stock at the exercise price of $4.695, which
was higher than

   (ALL INFORMATION WITH RESPECT TO JUNE 30, 1998 AND 1997 IS UNAUDITED)     
   
the then estimated fair market value of a share of the Company's common stock.
The exercise price is subject to adjustment in limited situations involving
antidilution as defined in the agreement. As a result of such dilution, the
exercise price is $4.695 per share at June 30, 1998. The warrant may be
exercised at any time prior to September 22, 2004. The Company has no
obligations to repurchase the warrants from the bank.     
   
  In May 1998, the Company negotiated an increase of the Line to $10,000,000,
including a $7,000,000 revolving facility for working capital and $3,000,000
lease facility, extended the maturity to December 31, 1999, and reduced the
interest rate to prime for the revolving facility and prime plus 0.75% for the
lease facility; all other terms substantially remained the same. In addition,
the commitment letter also includes a non-revolving line of credit for
$3,000,000, which bears interest at the bank's prime rate plus 0.75% per year,
and matures on May 12, 1999, if not renewed. At December 31, 1997 and June 30,
1998, there have been no borrowings under either agreement.     
 
7.  COMMITMENTS AND CONTINGENCIES:
 
 Leases
 
  The Company leases its facilities and certain computer and office equipment
under noncancelable leases for varying periods through 2002. The Company's
lease obligations are collateralized by certain assets at December 31, 1997.
The following are the minimum lease obligations under these leases at December
31, 1997:

Homesteaders may redeem GeoPoints to upgrade their Web site or purchase goods
from the Company's GeoStore. At December 31, 1996 and 1997, the Company has
accrued $38,000 and $463,000 for possible future redemption of GeoPoints;
these amounts are included in Accrued Expenses.
 
 Contingencies
 
  From time to time, the Company has been party to various litigation and
administrative proceedings relating to claims arising from its operations in
the normal course of business. Management believes that the resolution of
these matters will not have a material adverse effect on the Company's
business, results of operations, financial condition and cash flows.
 
8. CAPITALIZATION
 
  As of December 31, 1997, the Company had six series of Mandatory Redeemable
Convertible Preferred Stock (collectively "Preferred Stock") authorized and
outstanding. The holders of the various series of Preferred Stock generally
have the same rights and privileges; significant differences are discussed
below.
 
  The holders of the Preferred Stock are entitled to a discretionary
noncumulative dividend as specified below which is mandatory in the event of a
liquidation (not included in the liquidation preference below), and are
entitled to the number of votes equal to the number of shares of common stock
that could be converted on the date of the vote. Upon liquidation, the holders
of the Preferred Stock receive, prior and in preference to the holders of
common stock their liquidation preference plus accrued dividends at the stated
rate, from the date of issuance to the date payment is made available.
Redemption, at the option of the holders of Preferred Stock, may be elected
beginning on January 1, 2001 at which time, the redemption preference plus
seven percent per annum, on a cumulative basis is due. At the option of the
holders of Preferred Stock, each share of Preferred Stock is convertible at
the stated conversion price per share, subject to adjustment as defined in the
Certificate of Incorporation.
   
  During the year ended December 31, 1995, the Company issued 1,200,000 shares
of Convertible Preferred Stock Series C in consideration for $0.3217 per share
in the form of the cancellation of shares of common stock and conversion of a
note payable of $386,000 to the Company's Chairman and Founder. In connection
with the Series F Stock issuance, the Convertible Preferred Stock Series C
became Mandatory Redeemable Convertible Preferred Stock.     
   
  During the year ended December 31, 1996, the Company issued 3,108,000 and
2,900,000 shares of Series A Stock and Series B Stock for $1,000,000 and
$1,100,000, respectively. During January and February 1997, the Company issued
10,169,492 shares of Series D Stock for approximately $9,000,000. In October
and December 1997, the Company issued 1,428,564 and 814,270 shares of Series E
Stock at $3.50 and $7.4254 per share, respectively for total cash
consideration of $9,750,000 and 20,242 shares of Yahoo! stock valued at
approximately $1,300,000 which resulted in the recording of a subscription
receivable for approximately $6,000,000 at December 31, 1997. The subscription
receivable was collected in January 1998 and the Yahoo! stock was subsequently
sold.     
   
  In December 1997, the Company sold 2,552,576 shares of Series F Stock for
approximately $19,000,000 which resulted in the recording of a subscription
receivable at December 31, 1997. The subscription receivable was collected in
January 1998.

</TABLE>    
   
  The shares of Series E Stock sold in December 1997 (814,270 shares at $7.43
per share) have a redemption preference of $3.50 per share. The proceeds
received in excess of the redemption preference ($3,196,000) have been
recorded as additional paid-in capital.     
 
  As of December 31, 1997, the holders of Series A through F Stock may, at
their option, on each of January 1, 2001, January 1, 2002 and January 1, 2003,
require the Company to redeem shares equal to one-third of the total number of
shares of all Preferred Stock outstanding as of January 1, 2001. Any shares of
Preferred Stock to be redeemed shall be redeemed ratably among all holders of
Preferred Stock, based upon the respective redemption price of such shares.
Additionally, the holders of not less than 80% of the Preferred Stock then
outstanding, voting as a single class, may, at any time on or after December
31, 1998, require the Company to redeem all of the shares of Preferred Stock
in the event that the Company has not by such time consummated (i) a
"Qualified Public Offering" of its securities (as defined in the Certificate
of Incorporation), or (ii) a sale of the Company that meets certain
requirements.
 
  Each share of Series A through F Stock shall be converted into common stock
automatically upon the closing of the sale of the Company's securities in a
firm commitment underwritten public offering from which the Company receives
gross proceeds of not less than $20,000,000 and which is a Qualified Public
Offering as defined in the Certificate of Incorporation.
   
  At December 31, 1997 and June 30, 1998, the Company has reserved
approximately 22,230,000 shares of common stock for the future conversion of
the Series A through F Stock.     
 
 Warrants
   
  In connection with the Series D Stock issuance, the Company issued a warrant
to a bank to purchase 64,972 of the Company's Series D Preferred Stock at
$0.885 per share, exercisable at any time prior to January 12, 2002. On
December 31, 1997, the bank converted this warrant (on a net basis), and the
Company issued 57,226 shares of Series D Preferred Stock. The Bank immediately
sold these shares in connection with the Series E and F Preferred Stock
issuances. Also see Notes 6 and 10 of Notes to Financial Statements for a
warrant issued in connection with a line of credit, and options issued to a
Series D Preferred stockholder and others pursuant to stock option agreements.

  The primary components of temporary differences which gave rise to deferred
taxes at December 31 are:

</TABLE>
   
  As a result of the Company's loss history, management believes a valuation
allowance for the entire net deferred tax assets, after considering deferred
tax liabilities, is required. The change in the valuation allowance was an
increase of $3,557,000 in 1997. As of December 31, 1997, the Company had
federal and state net operating loss carryforwards of approximately
$11,250,000 and $10,650,000, respectively. Federal and state net operating
loss expirations begin in 2010 and 2002, respectively. Due to changes in
ownership (See Note 8), the Company will be limited in the annual utilization
of its net operating loss carryforwards.     
 
10.  STOCK OPTIONS:
   
  From inception through December 31, 1997, the Company has been authorized to
and has granted a total of 5,555,000 options to purchase its common stock; in
April and May 1998, the Board of Directors approved an increase in the total
number of shares issuable under the plan by 2,233,000 and 600,000,
respectively, increasing the total available to 8,388,000 at June 30, 1998.
    
  In 1997, the Company adopted the 1997 Stock Option Plan (the "Plan"), which
provides for issuance of both non-statutory and incentive stock options to
employees, officers, directors and consultants of the Company. Incentive stock
options may be granted at no less than 100% of the fair market value of the
Company's common stock on the date of grant as determined by the Board of
Directors (110% if granted to an employee who owns 10% or more of the common
stock). Options granted to date generally vest ratably over a four-year period
from the date of grant and are generally exercisable for a period of no longer
than seven years from the date of grant (five years if granted to an
individual who owns 10% or more of the common stock). In the event option
holders cease to be employed by the Company, all unvested options are
forfeited and, provided that the employee's employment has not been terminated
for cause, all vested options may be exercised within a period of up to 90
days after termination; the Company and the Company's preferred stockholders
have rights to repurchase any shares purchased through the exercise of an
option.

  In connection with its Series D stock offering in early 1997, the Company
granted options to purchase 1,000,000 shares of its common stock at an
exercise price of $0.885 per share to CMG@Ventures; these options vested
immediately and are exercisable by January 13, 2004. The exercise price was in
excess of the then estimated fair market value of a common share. The Company
has no obligation to repurchase the option from CMG@Ventures. At that time,
the Company also granted an option to purchase 1,000,000 shares of its common
stock at an exercise price of $0.885 per share to certain officers, directors
and consultants to the Company. These options generally vest over a four year
period from the date of grant and are generally exercisable by January 13,
2004. In certain circumstances, the vesting of these options may accelerate,
and there are certain participation rights in the event of a liquidation.     
 
  A summary of the status of the Company's stock options, as of December 31,
1996 and 1997, and the changes during the years ended on those dates is

  At December 31, 1997 and June 30, 1998, the Company had reserved a total of
5,531,000 and 7,329,000 shares of common stock for issuance to its stock
option holders.     
   
  In connection with its grants of options, the Company has recognized
unearned deferred compensation expense of $684,000 for the year ended December
31, 1997. This amount will be amortized over the vesting periods ranging from
48 to 72 months from the date of grant; $24,000 and $290,000 was expensed
during the year ended December 31, 1997 and the period ended June 30, 1998,
respectively.     
   
  For the six months ended June 30, 1998, the Company granted options to
purchase 3,169,000 shares of its common stock to employees and officers of the
Company. In conjunction with these grants, the Company recognized unearned
deferred compensation expense of $6,674,000 to be amortized over 48 to 72
months from the date of grant.

</TABLE>    
 
  The fair value of options granted during 1995, 1996 and 1997 is estimated as
$0, $0 and $50,000, respectively, on the dates of grants using the minimum
value method with the following assumptions: (i) dividend yield of 0%, (ii)
expected volatility of 0%, (iii) weighted-average risk-free interest rate
ranging from 6.04% to 6.8% for 1996 and 5.8% to 6.5% for 1997, (iv) weighted-
average expected life of five years for 1996 and 1997, and (v) assumed
forfeiture rate of 10% for 1996 and 1997.
 
  The Company applies APB No. 25 in accounting for its stock options granted
to employees and accordingly, no compensation expense has been recognized in
the financial statements (except for those options issued with exercise prices
at less than fair market value at date of grant). Had the Company determined
compensation expense based on the fair value at the grant date for its stock
options issued to employees under SFAS No. 123, the Company's net loss would
have been adjusted to the pro forma amounts indicated below:

11.  RETIREMENT PLAN:
 
  Effective July 1, 1997, the Company established a qualified 401(k) Profit
Sharing Plan (the "Plan") available to all employees who meet the Plan's
eligibility requirements. Employees may elect to contribute from 1% to 18% of
their eligible earnings to the Plan. This defined contribution plan provides
that the Company will, at its discretion, make contributions to the Plan on a
periodic basis. Additionally, the employer may match 33-1/3% of the first 6%
of the employees' contributions, which amounts vest over five years.
Terminations and forfeitures from the Plan are allocated to Plan participants
at year-end. The Company made contributions to the Plan of approximately
$10,000 in 1997.

</TABLE>    
 
  Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered
hereby, if any are taken.
 
  The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at
such price less a concession of $    per share. The Underwriters may allow,
and such dealers may reallow, a concession not in excess of $    per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the initial public offering price and other selling terms
may from time to time be varied by the representatives.
 
  The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of
additional shares of Common Stock to cover over-allotments, if any. If the
Underwriters exercise their over-allotment option, the Underwriters have
severally agreed, subject to certain conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the     shares of Common Stock
offered.
   
  The Company, its directors and officers, and substantially all of its other
stockholders and holders of options to purchase Common Stock, have agreed
that, subject to certain exceptions, during the period beginning from the date
of this Prospectus and continuing to and including the date 180 days after the
date of the Prospectus, they will not offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock or of any other securities of
the Company (other than, in the case of the Company, pursuant to the Purchase
Agreement related to the purchase of the Technology, or stock incentive and
employee stock purchase plans existing on the date of this Prospectus) which
are substantially similar to the shares of Common Stock or which are
convertible or exchangeable into securities which are substantially similar to
the shares of Common Stock without the prior written consent of the
representatives, except for the shares of Common Stock offered in connection
with the     
 
                                      U-1
<PAGE>
 
   
offering; provided, that one affiliate of the Company who is subject to a
lock-up agreement and the volume restrictions of Rule 144 will be permitted to
sell up to $1.0 million of Common Stock commencing 91 days after the date of
this Prospectus.     
 
  Prior to the offering, there has been no public market for the shares of
Common Stock. The initial public offering price will be negotiated among the
Company and the representatives. Among the factors to be considered in
determining the initial public offering price of the Common Stock, in addition
to prevailing market conditions, will be the Company's historical performance,
estimates of the business potential and earnings prospects of the Company, an
assessment of the Company's management and the consideration of the above
factors in relation to market valuations of companies in related businesses.
 
  The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed 5% of the total number of shares of Common
Stock offered by them.
 
  In connection with the offering, the Underwriters may purchase and sell
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created by the Underwriters in connection with the offering. Stabilizing
transactions consist of certain bids or purchases for the purpose of
preventing or retarding a decline in the market price of the Common Stock; and
syndicate short positions created by the Underwriters involve the sale by the
Underwriters of a greater number of shares of Common Stock than they are
required to purchase from the Company in the offering. The Underwriters also
may impose a penalty bid, whereby selling concessions allowed to syndicate
members or other broker-dealers in respect of the securities sold in the
offering for their account may be reclaimed by the syndicate if such shares of
Common Stock are repurchased by the syndicate in stabilizing or covering
transactions. These activities may stabilize, maintain or otherwise affect the
market price of the Common Stock, which may be higher than the price that
might otherwise prevail in the open market in the absence of such activities.
These transactions may be effected on the Nasdaq National Market, in the over-
the-counter market or otherwise, and these activities, if commenced, may be
discontinued at any time.
 
  The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act, subject to
certain limitations.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Company's Certificate of Incorporation (the "Certificate") provides
that, except to the extent prohibited by the Delaware General Corporation Law
(the "DGCL"), the Company's directors shall not be personally liable to the
Company or its stockholders for monetary damages for any breach of fiduciary
duty as directors of the Company. Under the DGCL, the directors have a
fiduciary duty to the Company which is not eliminated by this provision of the
Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of nonmonetary relief will remain available. In
addition, each director will continue to be subject to liability under the
DGCL for breach of the director's duty of loyalty to the Company, for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or involving intentional misconduct, for knowing violations of 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
prohibited by DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the Federal securities laws or
state or Federal environmental laws. The Company has obtained liability
insurance for its officers and directors.
 
  Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out
of their capacity or status as directors and officers, provided that this
provision shall not eliminate or limit the liability of a director: (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any
other rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL and provides that the
Company shall fully indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil,
 
                                     II-1
<PAGE>
 
criminal, administrative or investigative) by reason of the fact that such
person is or was a director or officer of the Company, or is or was serving at
the request of the Company as a director or officer of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.
 
  The Company, with the approval of the Board of Directors, intends to obtain
directors' and officers' liability insurance prior to the effectiveness of
this offering.
 
  There is no pending litigation or proceeding involving any director,
officer, employee or agent of the Company in which indemnification will be
required or permitted. Moreover, the Company is not aware of any threatened
litigation or proceeding that might result in a claim for such
indemnification. The Company believes that the foregoing indemnification
provisions and agreements are necessary to attract and retain qualified
persons as directors and executive officers.
 
  The Underwriting Agreement (the form of which is filed as Exhibit 1.1
hereto) provides for indemnification by the Underwriters of the Company and
its officers and directors, and by the Company of the Underwriters, for
certain liabilities arising under the Securities Act or otherwise.

  Common Stock at the initial public offering price.     
 
  None of the foregoing transactions involved any public offering, and the
Company believes that each transaction was exempt from the registration
requirements of the Securities Act by virtue of Section 4(2) thereof,
Regulation D promulgated thereunder or Rule 701 pursuant to compensatory
benefit plans and contracts relating to compensation as provided under such
Rule 701, or with respect to paragraph (13) above, in reliance on Rule
145(a)(2) under the Securities Act. The recipients in each such transaction
represented their intention 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 instruments
issued in such transactions. All recipients had adequate access, through their
relationships with the Company, to information about the Company.

ITEM 17. UNDERTAKINGS
 
  The Company hereby undertakes to provide to the Underwriters at the closing
specified in the Underwriting Agreements certificates in such denominations
and registered in such names as required by the Underwriters to permit prompt
delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has
been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Company of expenses incurred or paid by a director, officer or controlling
person of the Company in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  The undersigned Company hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus as filed as part
  of this Registration Statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the Company 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
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

          under the laws of each other jurisdiction in which it owns or leases

          counsel being entitled to rely in respect of the opinion in this
          clause upon opinions of local counsel and in respect of matters of
          fact upon certificates of officers of the Company, provided that such
          counsel shall state that they believe that both you and they are
          justified in relying upon such opinions and certificates);

              (iv)    Any real property and buildings held under lease by the
          Company are

          held by it under valid, subsisting and enforceable leases;

              (v)     To such counsel's knowledge and other than as set forth in
          the Prospectus, there are no legal or governmental proceedings pending
          to which the Company is a party or of which any property of the
          Company is the subject which, if determined adversely to the Company,
          would individually or in the aggregate have a material adverse effect
          on the current or future consolidated financial position,
          stockholders' equity or results of operations of the Company; and, to
          such counsel's knowledge, except as set forth in the Prospectus, no

          breach or violation of any of the terms or provisions of, or
          constitute a default under, any indenture, mortgage, deed of trust,
          loan agreement or other agreement or instrument to which the Company
          is a party or by which the Company is bound or to which any of the
          property or assets of the Company is subject which is filed as an
          exhibit to the Registration Statement or is identified by you or in a
          certificate of an officer of the Company as being material to the
          Company, nor will such action result in any violation of the
          provisions of the Certificate of Incorporation or By-laws of the
          Company or any statute or any order, rule or regulation known to such
          counsel of any court or governmental agency or body having
          jurisdiction over the Company or any of its properties;

              (viii)  No consent, approval, authorization, order, registration
          or qualification of or with any such court or governmental agency or
          body is required for the issue and sale of the Shares or the
          consummation by the Company of the transactions contemplated by this
          Agreement, except the registration under the Act of the Shares and
          under the Exchange Act of the Stock, and such consents, approvals,
          authorizations, registrations or qualifications as may be required

              (ix)    To the knowledge of such counsel, the Company is not in
          violation of its Certificate of Incorporation or By-laws or in default

          deed of trust, loan agreement, lease or other agreement or instrument
          to which it is a party or by which it or any of its properties may be
          bound (such counsel being entitled to rely in respect of the opinion
          in this clause upon an opinion of Edward J. Pierce, Vice President,
          Legal Affairs and General Counsel of the Company, provided that such
          counsel shall state that both you and they are justified in relying
          upon such opinion);

<PAGE>
 
              (x)    The statements set forth in the Prospectus under the
          caption "Description of Capital Stock", insofar as they purport to
          constitute a summary of the terms of the Stock, and under the caption
          "Underwriting", insofar as they purport to describe the provisions of
          the laws and documents referred to therein, constitute an accurate,
          fair and reasonable summary;

              (xi)   The Company is not an "investment company" or an entity
          "controlled" by an "investment company", as such terms are defined in
          the Investment Company Act; and

              (xii)  The Registration Statement and the Prospectus and any
          further amendments and supplements thereto made by the Company prior
          to such Time of Delivery (other than the financial statements and
          related schedules therein, as to which such counsel need express no
          opinion) comply as to form in all material respects with the
          requirements of the Act and the rules and regulations thereunder,
          although they do not assume any responsibility for the accuracy,
          completeness or fairness of the statements contained in the
          Registration Statement or the Prospectus, except for those referred to
          in the opinion in subsection (x) of this Section 7(c); they have no
          reason to believe that, as of its effective date, the Registration
          Statement or any further amendment thereto made by the Company prior
          to such Time of Delivery (other than the financial statements and
          related statements and related schedules therein, as to which such
          counsel need express no opinion) contained an untrue statement of a
          material fact or omitted to state a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading or that, as of its date, the Prospectus or any further
          amendment or supplement thereto made by the Company prior to such Time
          of Delivery (other than the financial statements and related schedules
          therein, as to which such counsel need express no opinion) contained
          an untrue statement of a material fact or omitted to state a material
          fact necessary to make the statements therein, in the light of the
          circumstances under which they were made, not misleading or that, as
          of such Time of Delivery, either the Registration Statement or the
          Prospectus or any further amendment or supplement thereto made by the
          Company prior to such Time of Delivery (other than the financial
          statements and related schedules therein, as to which such counsel
          need express no opinion) contains an untrue statement of a material
          fact or omits to state a material fact necessary to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading; and they do not know of any amendment to
          the Registration Statement required to be filed or of any contracts or
          other documents of a character required to be filed as an exhibit to
          the Registration Statement or required to be described in the
          Registration Statement or the Prospectus which are not filed or
          described as required.

          In rendering such opinion, such counsel may state that they express no
     opinion as to any laws other than the laws the States of California and New
     York, the Delaware General Corporation law and the federal laws of the
     United States;

          (d) Each of Seyfarth, Shaw, Fairweather & Geraldson, special counsel
     to the Company, and Piper & Marbury, LLP, special counsel to the Company,
     shall have

                                      -12-
<PAGE>
 
     furnished to you their written opinion (drafts of such opinions
     are attached hereto as Annex II(b) and Annex II(c), respectively), dated
     such Time of Delivery, in form and substance satisfactory to you, to the
     effect that:

              (i)  The statements set forth under the caption "Risk Factors--
          Government Regulation and Legal Uncertainties" in the Registration
          Statement and Prospectus, or any further amendment or supplement
          thereto made by the Company prior to such Time of Delivery, insofar as
          such statements purport to constitute a summary of legal matters,
          documents or proceedings referred to therein, constitute an accurate,
          fair and reasonable summary; and

              (ii) Such counsel has represented the Company in connection with
          specific proceedings before the Federal Trade Commission ("FTC") and
          has reviewed the statements set forth under the caption "Risk Factors-
          -Government Regulation and Legal Uncertainties" in the Registration
          Statement and Prospectus and all amendments or supplements thereto
          made by the Company prior to such Time of Delivery.  Such counsel has
          not independently verified the accuracy, completeness or fairness of
          the statements made or the information contained in the Registration
          Statement or the Prospectus or any further amendment or supplement
          thereto made by the Company prior to such Time of Delivery, and,
          except with respect to the statements referred to in the previous
          paragraph, such counsel is unable to offer and does not assume any
          responsibility therefor.  On the basis of the information gained by
          such counsel in the course of representation of the Company in
          connection with the FTC proceedings described, nothing has come to the
          attention of such counsel that leads such counsel to believe that, as
          of the effective date of the Registration Statement and as of such
          Time of Delivery, the statements set forth under the caption "Risk
          Factors--Government Regulation and Legal Uncertainties" in the
          Registration Statement or the Prospectus or any further amendment or
          supplement thereto made by the Company prior to such Time of Delivery
          contain any untrue statement of a material fact or omit to state a
          material fact required to be stated therein or necessary to make the
          statements therein, in light of the circumstances under which they
          were made, not misleading.

          In rendering such opinion, such counsel may state that they express no
     opinion as to the laws of any jurisdiction outside the United States;

          (e) Nagauhima & Ohno, counsel to GeoCities Japan, shall have furnished
     to you their written opinion (a draft of such opinion is attached hereto as
     Annex II(d)), dated such Time of Delivery, in form and substance
     satisfactory to you, to the effect that GeoCities Japan has been duly
     incorporated and is validly existing as a corporation in good standing
     under the laws of its jurisdiction of incorporation; and all of the issued
     shares of capital stock of GeoCities Japan have been duly and validly
     authorized and issued, are fully paid and non-assessable, and (except as
     otherwise set forth in the Prospectus) are owned by the Company, and, to
     the knowledge of such counsel, such shares are owned free and clear of all
     liens, encumbrances, equities or claims;

          (f) On the date of the Prospectus at a time prior to the execution of
     this Agreement, at 9:30 a.m., New York City time, on the effective date of
     any post-effective

                                      -13-
<PAGE>
 
     amendment to the Registration Statement filed subsequent to the date of
     this Agreement and also at each Time of Delivery, Coopers & Lybrand, L.L.P.
     shall have furnished to you a letter or letters, dated the respective dates
     of delivery thereof, in form and substance satisfactory to you, to the
     effect set forth in Annex I hereto (the executed copy of the letter
     delivered prior to the execution of this Agreement is attached as Annex
     I(a) hereto and a draft of the form of letter to be delivered on the
     effective date of any post-effective amendment to the Registration
     Statement and as of each Time of Delivery is attached as Annex I(b)
     hereto);

          (g) (i)  The Company shall not have sustained since the date of the
     latest audited financial statements included in the Prospectus any loss or
     interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree, otherwise than as set forth
     or contemplated in the Prospectus, and (ii) since the respective dates as
     of which information is given in the Prospectus there shall not have been
     any change in the capital stock or long-term debt of the Company or any
     change, or any development involving a prospective change, in or affecting
     the general affairs, management, financial position, stockholders' equity
     or results of operations of the Company, otherwise than as set forth or
     contemplated in the Prospectus, the effect of which, in any such case
     described in Clause (i) or (ii), is in the judgment of the Representatives
     so material and adverse to the Company as to make it impracticable or
     inadvisable to proceed with the public offering or the delivery of the
     Shares being delivered at such Time of Delivery on the terms and in the
     manner contemplated in the Prospectus;

          (h) On or after the date hereof (i) no downgrading shall have occurred
     in the rating accorded the Company's debt securities or preferred stock by
     any "nationally recognized statistical rating organization", as that term
     is defined by the Commission for purposes of Rule 436(g)(2) under the Act,
     and (ii) no such organization shall have publicly announced that it has
     under surveillance or review, with possible negative implications, its
     rating of any of the Company's debt securities or preferred stock;

          (i) On or after the date hereof there shall not have occurred any of
     the following: (i) a suspension or material limitation in trading in
     securities generally on the New York Stock Exchange or NASDAQ;  (ii) a
     suspension or material limitation in trading in the Company's securities on
     NASDAQ; (iii) a general moratorium on commercial banking activities
     declared by either Federal or New York or California State authorities; or
     (iv) the outbreak or escalation of hostilities involving the United States
     or the declaration by the United States of a national emergency or war, if
     the effect of any such event specified in this Clause (iv) in the judgment
     of the Representatives makes it impracticable or inadvisable to proceed
     with the public offering or the delivery of the Shares being delivered at
     such Time of Delivery on the terms and in the manner contemplated in the
     Prospectus;

          (j) The Shares to be sold by the Company at such Time of Delivery
     shall have been duly listed for quotation on NASDAQ;

          (k) The Company has obtained and delivered to the Underwriters
     executed copies of an agreement from each securityholder of the Company to
     the effect set forth in Subsection 5(e) hereof in form and substance
     satisfactory to you; provided, however,

                                      -14-
<PAGE>
 
     that such agreement with John Rezner may allow Mr. Rezner to sell shares of
     Stock on Nasdaq resulting in gross proceeds to Mr. Rezner of not more than
     $1,000,000 during the period commencing on the date 91 days after the date
     of the Prospectus and terminating on the date 180 days after the date of
     the Prospectus;

          (l) The Company shall have complied with the provisions of Section
     5(c) hereof with respect to the furnishing of prospectuses on the New York
     Business Day next succeeding the date of this Agreement;

          (m) The Company shall have furnished or caused to be furnished to you
     at such Time of Delivery certificates of officers of the Company
     satisfactory to you as to the accuracy of the representations and
     warranties of the Company herein at and as of such Time of Delivery, as to
     the performance by the Company of all of its obligations hereunder to be
     performed at or prior to such Time of Delivery, as to the matters set forth
     in the introductory paragraph to this Section and subsection (g) of this
     Section and as to such other matters as you may reasonably request.

     8.   (a) The Company will indemnify and hold harmless each Underwriter
     against any losses, claims, damages or liabilities, joint or several, to
     which such Underwriter may become subject, under the Act or otherwise,
     insofar as such losses, claims, damages or liabilities (or actions in
     respect thereof) arise out of or are based upon an untrue statement or
     alleged untrue statement of a material fact contained in any Preliminary
     Prospectus, the Registration Statement or the Prospectus, or any amendment
     or supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     will reimburse each Underwriter for any legal or other expenses reasonably
     incurred by such Underwriter in connection with investigating or defending
     any such action or claim as such expenses are incurred; provided, however,
     that the Company shall not be liable in any such case to the extent that
     any such loss, claim, damage or liability arises out of or is based upon an
     untrue statement or alleged untrue statement or omission or alleged
     omission made in any Preliminary Prospectus, the Registration Statement or
     the Prospectus or any such amendment or supplement in reliance upon and in
     conformity with written information furnished to the Company by any
     Underwriter through Goldman, Sachs & Co. expressly for use therein.


          (b) Each Underwriter will indemnify and hold harmless the Company
     against any losses, claims, damages or liabilities to which the Company may
     become subject, under the Act or otherwise, insofar as such losses, claims,
     damages or liabilities (or actions in respect thereof) arise out of or are
     based upon an untrue statement or alleged untrue statement of a material
     fact contained in any Preliminary Prospectus, the Registration Statement or
     the Prospectus, or any amendment or supplement thereto, or arise out of or
     are based upon the omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, in each case to the extent, but only to the extent,
     that such untrue statement or alleged untrue statement or omission or
     alleged omission was made in any Preliminary Prospectus, the Registration
     Statement or the Prospectus or any such amendment or supplement in reliance
     upon and in conformity with written information furnished to the Company by
     such Underwriter through Goldman, Sachs & Co. expressly for use therein;
     and will reimburse the Company for any legal or other expenses

                                      -15-

     reasonably incurred by the Company in connection with investigating or
     defending any such action or claim as such expenses are incurred.

          (c) Promptly after receipt by an indemnified party under subsection
     (a) or (b) above of notice of the commencement of any action, such
     indemnified party shall, if a claim in respect thereof is to be made
     against the indemnifying party under such subsection, notify the
     indemnifying party in writing of the commencement thereof; but the omission
     so to notify the indemnifying party shall not relieve it from any liability
     which it may have to any indemnified party otherwise than under such
     subsection.  In case any such action shall be brought against any
     indemnified party and it shall notify the indemnifying party of the
     commencement thereof, the indemnifying party shall be entitled to
     participate therein and, to the extent that it shall wish, jointly with any
     other indemnifying party similarly notified, to assume the defense thereof,
     with counsel satisfactory to such indemnified party (who shall not, except
     with the consent of the indemnified party, be counsel to the indemnifying
     party), and, after notice from the indemnifying party to such indemnified
     party of its election so to assume the defense thereof, the indemnifying
     party shall not be liable to such indemnified party under such subsection
     for any legal expenses of other counsel or any other expenses, in each case
     subsequently incurred by such indemnified party, in connection with the
     defense thereof other than reasonable costs of investigation.  No
     indemnifying party shall, without the written consent of the indemnified
     party, effect the settlement or compromise of, or consent to the entry of
     any judgment with respect to, any pending or threatened action or claim in
     respect of which indemnification or contribution may be sought hereunder
     (whether or not the indemnified party is an actual or potential party to
     such action or claim) unless such settlement, compromise or judgment (i)
     includes an unconditional release of the indemnified party from all
     liability arising out of such action or claim and (ii) does not include a
     statement as to or an admission of fault, culpability or a failure to act,
     by or on behalf of any indemnified party.

          (d) If the indemnification provided for in this Section 8 is
     unavailable to or insufficient to hold harmless an indemnified party under
     subsection (a) or (b) above in respect of any losses, claims, damages or
     liabilities (or actions in respect thereof) referred to therein, then each
     indemnifying party shall contribute to the amount paid or payable by such
     indemnified party as a result of such losses, claims, damages or
     liabilities (or actions in respect thereof) in such proportion as is
     appropriate to reflect the relative benefits received by the Company on the
     one hand and the Underwriters on the other from the offering of the Shares.
     If, however, the allocation provided by the immediately preceding sentence
     is not permitted by applicable law or if the indemnified party failed to
     give the notice required under subsection (c) above, then each indemnifying
     party shall contribute to such amount paid or payable by such indemnified
     party in such proportion as is appropriate to reflect not only such
     relative benefits but also the relative fault of the Company on the one
     hand and the Underwriters on the other in connection with the statements or
     omissions which resulted in such losses, claims, damages or liabilities (or
     actions in respect thereof), as well as any other relevant equitable
     considerations.  The relative benefits received by the Company on the one
     hand and the Underwriters on the other shall be deemed to be in the same
     proportion as the total net proceeds from the offering of the Shares
     purchased under this Agreement (before deducting expenses) received by the
     Company bear to the total underwriting discounts and commissions received
     by the Underwriters with respect to the Shares

                                      -16-
<PAGE>
 
     purchased under this Agreement, in each case as set forth in the table on
     the cover page of the Prospectus. The relative fault shall be determined by
     reference to, among other things, whether the untrue or alleged untrue
     statement of a material fact or the omission or alleged omission to state a
     material fact relates to information supplied by the Company on the one
     hand or the Underwriters on the other and the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission. The Company and the Underwriters agree that it would
     not be just and equitable if contributions pursuant to this subsection (d)
     were determined by pro rata allocation (even if the Underwriters were
     treated as one entity for such purpose) or by any other method of
     allocation which does not take account of the equitable considerations
     referred to above in this subsection (d). The amount paid or payable by an
     indemnified party as a result of the losses, claims, damages or liabilities
     (or actions in respect thereof) referred to above in this subsection (d)
     shall be deemed to include any legal or other expenses reasonably incurred
     by such indemnified party in connection with investigating or defending any
     such action or claim. Notwithstanding the provisions of this subsection
     (d), no Underwriter shall be required to contribute any amount in excess of
     the amount by which the total price at which the Shares underwritten by it
     and distributed to the public were offered to the public exceeds the amount
     of any damages which such Underwriter has otherwise been required to pay by
     reason of such untrue or alleged untrue statement or omission or alleged
     omission. No person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Act) shall be entitled to contribution from
     any person who was not guilty of such fraudulent misrepresentation. The
     Underwriters' obligations in this subsection (d) to contribute are several
     in proportion to their respective underwriting obligations and not joint.

          (e) The obligations of the Company under this Section 8 shall be in
     addition to any liability which the Company may otherwise have and shall
     extend, upon the same terms and conditions, to each person, if any, who
     controls any Underwriter within the meaning of the Act; and the obligations
     of the Underwriters under this Section 8 shall be in addition to any
     liability which the respective Underwriters may otherwise have and shall
     extend, upon the same terms and conditions, to each officer and director of
     the Company (including any person who, with his or her consent, is named in
     the Registration Statement as about to become a director of the Company)
     and to each person, if any, who controls the Company within the meaning of
     the Act.

     9.   (a) If any Underwriter shall default in its obligation to purchase
     the Shares which it has agreed to purchase hereunder at a Time of Delivery,
     you may in your discretion arrange for you or another party or other
     parties to purchase such Shares on the terms contained herein.  If within
     thirty-six hours after such default by any Underwriter you do not arrange
     for the purchase of such Shares, then the Company shall be entitled to a
     further period of thirty-six hours within which to procure another party or
     other parties satisfactory to you to purchase such Shares on such terms.
     In the event that, within the respective prescribed periods, you notify the
     Company that you have so arranged for the purchase of such Shares, or the
     Company notifies you that it has so arranged for the purchase of such
     Shares, you or the Company shall have the right to postpone such Time of
     Delivery for a period of not more than seven days, in order to effect
     whatever changes may thereby be made necessary in the Registration
     Statement or the Prospectus, or in any other documents or arrangements, and
     the Company agrees to file promptly any amendments to the Registration
     Statement or the Prospectus which in your

                                      -17-
<PAGE>
 
     opinion may thereby be made necessary. The term "Underwriter" as used in
     this Agreement shall include any person substituted under this Section with
     like effect as if such person had originally been a party to this Agreement
     with respect to such Shares.

          (b) If, after giving effect to any arrangements for the purchase of
     the Shares of a defaulting Underwriter or Underwriters by you and the
     Company as provided in subsection (a) above, the aggregate number of such
     Shares which remains unpurchased does not exceed one-eleventh of the
     aggregate number of all the Shares to be purchased at such Time of
     Delivery, then the Company shall have the right to require each non-
     defaulting Underwriter to purchase the number of Shares which such
     Underwriter agreed to purchase hereunder at such Time of Delivery and, in
     addition, to require each non-defaulting Underwriter to purchase its pro
     rata share (based on the number of Shares which such Underwriter agreed to
     purchase hereunder) of the Shares of such defaulting Underwriter or
     Underwriters for which such arrangements have not been made; but nothing
     herein shall relieve a defaulting Underwriter from liability for its
     default.

          (c) If, after giving effect to any arrangements for the purchase of
     the Shares of a defaulting Underwriter or Underwriters by you and the
     Company as provided in subsection (a) above, the aggregate number of such
     Shares which remains unpurchased exceeds one-eleventh of the aggregate
     number of all the Shares to be purchased at such Time of Delivery or if the
     Company shall not exercise the right described in subsection (b) above to
     require non-defaulting Underwriters to purchase Shares of a defaulting
     Underwriter or Underwriters, then this Agreement (or, with respect to the
     Second Time of Delivery, the obligations of the Underwriters to purchase
     and of the Company to sell the Optional Shares) shall thereupon terminate,
     without liability on the part of any non-defaulting Underwriter or the
     Company, except for the expenses to be borne by the Company and the
     Underwriters as provided in Section 6 hereof and the indemnity and
     contribution agreements in Section 8 hereof; but nothing herein shall
     relieve a defaulting Underwriter from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Underwriters, as set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Shares.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
the Company shall not then be under any liability to any Underwriter except as
provided in Sections 6 and 8 hereof; but, if for any other reason, any Shares
are not delivered by or on behalf of the Company as provided herein, the Company
will reimburse the Underwriters through you for all out-of-pocket expenses
approved in writing by you, including fees and disbursements of counsel,
reasonably incurred by the Underwriters in making preparations for the purchase,
sale and delivery of the Shares not so delivered, but the Company shall then be
under no further liability to any Underwriter in respect of the Shares not so
delivered except as provided in Sections 6 and 8 hereof.

                                      -18-

     12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 32 Old Slip, 9th Floor, New York, New York  10004, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Chief Operating Officer; provided, however,
that any notice to an Underwriter pursuant to Section 8(c) hereof shall be
delivered or sent by mail, telex or facsimile transmission to such Underwriter
at its address set forth in its Underwriters' Questionnaire, or telex
constituting such Questionnaire, which address will be supplied to the Company
by you upon request.  Any such statements, requests, notices or agreements shall
take effect at the time of receipt thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and, to the extent provided in Sections 8 and
10 hereof, the officers and directors of the Company and each person who
controls the Company or any Underwriter, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement.  No purchaser of any of the
Shares from any Underwriter shall be deemed a successor or assign by reason
merely of such purchase.

     14.  Time shall be of the essence of this Agreement.  As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C.  is open for business.

     15.  This Agreement shall be governed by and construed in accordance with
the laws of the State of New York.

     16.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

              FORM OF COMFORT LETTER OF COOPERS & LYBRAND, L.L.P.

     Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

          (i)    They are independent certified public accountants with respect
     to the Company within the meaning of the Act and the applicable published
     rules and regulations thereunder;

          (ii)   In their opinion, the financial statements and any
     supplementary financial information and schedules (and, if applicable,
     financial forecasts and/or pro forma financial information) examined by
     them and included in the Prospectus or the Registration Statement comply as
     to form in all material respects with the applicable accounting
     requirements of the Act and the related published rules and regulations
     thereunder; and, if applicable, they have made a review in accordance with
     standards established by the American Institute of Certified Public
     Accountants of the unaudited interim financial statements, selected
     financial data, pro forma financial information, financial forecasts and/or
     condensed financial statements derived from audited financial statements of
     the Company for the periods specified in such letter, as indicated in their
     reports thereon, copies of which have been furnished to the representatives
     of the Underwriters (the "Representatives") and are attached hereto;

          (iii)  They have made a review in accordance with standards
     established by the American Institute of Certified Public Accountants of
     the unaudited condensed statements of income, balance sheets and statements
     of cash flows included in the Prospectus as indicated in their reports
     thereon copies of which are attached hereto; and on the basis of specified
     procedures including inquiries of officials of the Company who have
     responsibility for financial and accounting matters regarding whether the
     unaudited condensed financial statements referred to in paragraph
     (vi)(A)(i) below comply as to form in all material respects with the
     applicable accounting requirements of the Act and the related published
     rules and regulations, nothing came to their attention that caused them to
     believe that the unaudited condensed financial statements do not comply as
     to form in all material respects with the applicable accounting
     requirements of the Act and the related published rules and regulations;

          (iv)   The unaudited selected financial information with respect to
     the results of operations and financial position of the Company for each of
     the fiscal years included in the Prospectus agrees with the corresponding
     amounts (after restatements where applicable) in the audited financial
     statements for such fiscal years, copies of which have been furnished to
     the Representatives and are attached hereto;

          (v)    They have compared the information in the Prospectus under
     selected captions with the disclosure requirements of Regulation S-K and on
     the basis of limited procedures specified in such letter nothing came to
     their attention as a result of the foregoing procedures that caused them to
     believe that this information does not conform in all material respects
     with the disclosure requirements of Items 301, 302, 402 and 503(d),
     respectively, of Regulation S-K;
<PAGE>
 
          (vi) On the basis of limited procedures, not constituting an
     examination in accordance with generally accepted auditing standards,
     consisting of a reading of the unaudited financial statements and other
     information referred to below, a reading of the latest available interim
     financial statements of the Company, inspection of the minute books of the
     Company since the date of the latest audited financial statements included
     in the Prospectus, inquiries of officials of the Company responsible for
     financial and accounting matters and such other inquiries and procedures as
     may be specified in such letter, nothing came to their attention that
     caused them to believe that:

              (A) (i) the unaudited statements of income, balance sheets and
          statements of cash flows included in the Prospectus do not comply as
          to form in all material respects with the applicable accounting
          requirements of the Act and the related published rules and
          regulations, or (ii) any material modifications should be made to the
          unaudited condensed statements of income, balance sheets and
          statements of cash flows included in the Prospectus for them to be in
          conformity with generally accepted accounting principles;

              (B) any other unaudited income statement data and balance sheet
          items included in the Prospectus do not agree with the corresponding
          items in the unaudited financial statements from which such data and
          items were derived, and any such unaudited data and items were not
          determined on a basis substantially consistent with the basis for the
          corresponding amounts in the audited financial statements included in
          the Prospectus;

              (C) the unaudited financial statements which were not included in
          the Prospectus but from which were derived any unaudited condensed
          financial statements referred to in Clause (A) and any unaudited
          income statement data and balance sheet items included in the
          Prospectus and referred to in Clause (B) were not determined on a
          basis substantially consistent with the basis for the audited
          financial statements included in the Prospectus;

              (D) any unaudited pro forma condensed financial statements
          included in the Prospectus do not comply as to form in all material
          respects with the applicable accounting requirements of the Act and
          the published rules and regulations thereunder or the pro forma
          adjustments have not been properly applied to the historical amounts
          in the compilation of those statements;

              (E) as of a specified date not more than five days prior to the
          date of such letter, there have been any changes in the capital stock
          (other than issuances of capital stock upon exercise of options and
          stock appreciation rights, upon earn-outs of performance shares and
          upon conversions of convertible securities, in each case which were
          outstanding on the date of the latest financial statements included in
          the Prospectus) or any increase in the long-term debt of the Company,
          or any decreases in net current assets or stockholders' equity or
          other items specified by the Representatives, or any increases in any
          items specified by the Representatives, in each case as compared with
          amounts shown in the latest balance sheet included in the Prospectus,
          except in each case for changes, increases or decreases which the
          Prospectus discloses have occurred or may occur or which are described
          in such letter; and
<PAGE>
 
              (F) for the period from the date of the latest financial
          statements included in the Prospectus to the specified date referred
          to in Clause (E) there were any decreases in net revenues or operating
          profit or the total or per share amounts of net income or other items
          specified by the Representatives, or any increases in any items
          specified by the Representatives, in each case as compared with the
          comparable period of the preceding year and with any other period of
          corresponding length specified by the Representatives, except in each
          case for decreases or increases which the Prospectus discloses have
          occurred or may occur or which are described in such letter; and


         (vii)  In addition to the examination referred to in their report(s)
     included in the Prospectus and the limited procedures, inspection of minute
     books, inquiries and other procedures referred to in paragraphs (iii) and
     (vi) above, they have carried out certain specified procedures, not
     constituting an examination in accordance with generally accepted auditing
     standards, with respect to certain amounts, percentages and financial
     information specified by the Representatives, which are derived from the
     general accounting records of the Company, which appear in the Prospectus,
     or in Part II of, or in exhibits and schedules to, the Registration
     Statement specified by the Representatives, and have compared certain of
     such amounts, percentages and financial information with the accounting
     records of the Company and have found them to be in agreement.

                        WARRANT TO PURCHASE COMMON STOCK

                                   GEOCITIES

                         Void after September 22, 2004


This certifies that, for value received, Comerica Bank - California or assign is
entitled, subject to the terms set forth below, to purchase from GeoCities, a
California corporation (the "Company"), shares of the Company's common stock,
$0.005 par value per share (the "Common Stock"), as constituted on the date
hereof (the "Warrant Issue Date"), upon surrender hereof, at the principal
office of the Company referred to below, with the Notice of Exercise attached
hereto duly executed, and simultaneous payment therefor in lawful money of the
United States, or otherwise as hereinafter provided, at the exercise price (the
"Exercise Price") as set forth in Section 2 below. The number of, and exercise
price for, such shares of Common Stock are subject to adjustment as provided
herein.


   1.  Term of Warrant.  Subject to the terms and conditions set forth herein,
       ---------------                                                        
this Warrant shall be exercisable, in whole or in part, during the term
commencing on the Warrant Issue Date and terminating on or before September 22,
2004.

   2.  Exercise Price.  The Exercise Price shall be $9.85 per share, subject to
       --------------                                                          
adjustment as set forth in Section 3 below.

   3.  Antidilution Protection.  The number and kind of securities purchasable
       -----------------------                                                
upon the exercise of this Warrant and the Exercise Price shall be subject to
adjustment from time to time upon the happening of certain events, as follows:

       (a) If at any time or from time to time after the Warrant Issue Date the
outstanding shares of the Company's Common Stock shall be subdivided into a
greater number of shares thereof or a dividend in Common Stock shall be paid in
respect of Common Stock, the 

                                       1
<PAGE>
 
Exercise Price in effect immediately prior to such subdivision or at the record
date of such dividend shall, simultaneously with the effectiveness of such
subdivision or immediately after the record date of such dividend, be
proportionately reduced and, conversely, if the outstanding shares of the
Company's Common Stock shall be combined into a smaller number of shares
thereof, the Exercise Price in effect immediately prior to such combination
shall, simultaneously with the effectiveness of such combination, be
proportionately increased. Such adjustment shall be made successively whenever
any subdivision, combination or dividend in the Company's Common Stock shall
occur.

      (b) Subject to the Company's election described below, if at any time or
from time to time after the Warrant Issue Date there shall occur an Acquisition
(as defined below) then, upon the closing of any such Acquisition, the holder
hereof shall have the right thereafter to receive upon the exercise hereof the
kind and amount of shares of stock or other securities or property, or any
combination thereof, which the holder would have been entitled to receive if,
immediately prior to the record date for any such Acquisition the holder had
held the number of shares of Common Stock which were then purchasable upon the
exercise of this Warrant. In any such case, appropriate adjustment (as
determined by the Board of Directors of the Company) shall be made in the
application of the provisions set forth herein with respect to the rights and
interests thereafter of the holder such that the provisions set forth herein
(including provisions with respect the adjustment of the Exercise Price) shall
hereafter be applicable, as nearly as is reasonably practicable, in relation to
any shares of stock or other securities or property, or any combination thereof,
thereafter deliverable upon the exercise of this Warrant. Notwithstanding the
foregoing, the Company may, in its sole and absolute discretion, elect to
purchase the unexercised portion of the Warrant for cash upon the closing of any
Acquisition for an amount equal to (a) the fair market value of any
consideration that would have been received by the holder hereof in
consideration of shares of Common Stock had such holder exercised the
unexercised portion of this Warrant immediately before the record date for
determining the shareholders entitled to participate in the proceeds of the
Acquisition, less (b) the aggregate Warrant Price, but in no event less than
zero. The Company shall provide the holder of this Warrant with notice of such
election at least thirty (30) days prior to the closing of any such Acquisition.
For the purpose of this Warrant, "Acquisition" means a consolidation or merger
of the Company with or into any other corporation or corporations (other than a
wholly-owned subsidiary), or the sale, transfer or other disposition of all or
substantially all of the assets of the Company or the consummation of any
transaction or series of related transactions which results in the Company's
shareholders immediately prior to such transaction not holding at least 50% of
the voting power of the surviving or continuing entity.

      (c) If the Company at any time or from time to time after December 31,
1997 shall issue any shares of Common Stock (otherwise than as provided in
subparagraph (a) above) at a price per share less than the Exercise Price in
effect at the time of such issue, or without consideration, then, and thereafter
successively upon each such issue, the Exercise Price shall be, until further
adjusted as herein provided, an amount equal to the quotient, the numerator of
which is the sum of (A) the number of shares of Common Stock outstanding
immediately prior to such issue multiplied by the Exercise Price in effect
immediately prior to such issue plus (B) the aggregate consideration, if any,
received by the Company in connection with such issue, and

                                       2
<PAGE>
 
the denominator of which is the number of shares of Common Stock outstanding
immediately after such issue, computed to the nearest even cent.

     (d) If the Company at any time or from time to time after the Warrant Issue
Date shall issue (i) any security that is convertible into shares of the
Company's Common Stock or (ii) any rights or options to purchase Common Stock of
the Company, the Company shall be deemed to have issued the maximum number of
shares of Common Stock into which such convertible security may be converted,
and the maximum number of shares of Common Stock deliverable upon the exercise
of such rights or options, for (iii) the consideration received by the Company
for such convertible security or for such rights or options plus (iv) the
minimum consideration to be received by the Company for the Common Stock
issuable upon the conversion of such convertible securities or the exercise of
such rights or options. No further adjustment of the Exercise Price shall be
made as a result of the actual issuance of the shares of the Company's Common
Stock upon conversion of any convertible security or exercise of any rights or
options referred to in this subparagraph (d). On the termination of the right to
convert such convertible security, or on the expiration of such rights or
options, the Exercise Price hereunder shall be readjusted to such as would have
obtained had the adjustment made upon the issuance of such convertible security
or upon the issuance of such rights or options been made upon the basis of the
number of shares of Common Stock actually issued upon the conversion of such
convertible security or the exercise of such rights or options, and of the
consideration actually received by the Company upon such conversion or exercise.

      (e) For the purpose of each computation to be made as provided in the
foregoing paragraphs (a) through (d), the following provisions shall be
applicable:

          (i) In case of consideration consisting in whole or in part of cash,
the cash consideration shall be deemed to be the amount of cash constituting or
included in such consideration.

          (ii) In case of consideration consisting in whole or in part other
than cash, the amount of the consideration other than cash shall be deemed to be
the value of such consideration as determined in good faith by the Board of
Directors of the Company.

          (iii) Any securities (other than Common Stock) issued as a dividend on
the Common Stock shall be deemed to have been issued for no consideration.

          (iv) The consideration received or deemed to be received by the
Company for any share of Common Stock or other securities issued by it shall be
the amount of the consideration paid therefor by the first purchasers thereof
not acting as underwriters or dealers in connection with such issue, without
deduction for any expenses, commissions or underwriting discounts.

          (v) Upon each adjustment of the Exercise Price or the number of shares
purchasable upon exercise of this Warrant, a written instrument signed by the
chief financial officer of the Company setting forth such adjustment and the
computation and a

                                       3
<PAGE>
 
summary of the facts upon which it is based shall forthwith be prepared and
provided to the holder hereof.

          (vi) The number of shares of Common Stock outstanding at any given
time shall include the shares deemed to have been issued under paragraph (d)
above.

          (vii) Notwithstanding anything contained in this Section 3 to the
contrary, the issuance of any of the following securities by the Company shall
not constitute an issuance of securities for purposes of this paragraph 3 and
the provisions of this Section 3 shall not be applicable to any such issuance:
(i) options to purchase Common Stock previously granted or currently reserved
for granting to officers, directors, employees or consultants of the Company and
its subsidiaries either pursuant to any stock plan approved by the Company's
Board of directors or as otherwise approved by the Company's Board of Directors
("Stock Options"), (ii) any shares of Common Stock issuable upon exercise of
Stock Options, (iii) up to 500,000 shares of Common Stock issuable under stock
options granted to CMG@Ventures and approved by the Company's Board of
Directors, (iv) up to 500,000 shares of Common Stock issuable under stock
options granted to David Bohnett and certain other persons and approved by the
Company's Board of Directors, and (v) warrants to purchase up to 33,898 shares
of Series D Preferred Stock granted to Cupertino Bank and the shares issuable
upon exercise thereof.

      (f) In the event of (i) any taking by the Company of a record of the
holders of any class of securities for the purpose of determining the holders
thereof who are entitled to receive any dividend or other distribution, or (ii)
any capital reorganization of the Company, or any reclassification or
recapitalization of the Common Stock of the Company, or (iii) any consolidation
or merger of the Company with or into another corporation, or (iv) any sale of
all or substantially all of the property and assets of the Company to any other
person, or (v) any voluntary or involuntary dissolution, liquidation or winding
up of the Company, the Company shall mail to the holder of this Warrant a notice
specifying (1) the date on which any record is to be taken for the purpose of
determining the persons entitled to participate in such dividend or distribution
and a description of such dividend or distribution, (2) the date on which any
such reorganization, reclassification, recapitalization, consolidation, merger,
sale, dissolution, liquidation or winding up is expected to become effective,
and (3) the time, if any, as to when the holders of record of Common Stock (or
other securities) shall be entitled to exchange their shares of Common Stock (or
other securities) for securities or other property deliverable upon such
reorganization, reclassification, recapitalization, consolidation, merger, sale,
dissolution, liquidation or winding up. Such notice shall be mailed at least
fifteen (15) days prior to the date therein specified.

      (g) The Company shall not, by any voluntary action, avoid or seek to avoid
the observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 3 and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the holder against impairment.

  4. Shares Purchasable. The holder of this Warrant shall have the right, at any
     ------------------  
time or from time to time, to purchase up to 10,152 shares of fully paid and
nonassessable shares of the

above, by the surrender of this Warrant and the Notice of Exercise annexed
hereto duly completed and executed on behalf of the holder, at the office of the
Company (or such other office or agency of the Company as it may designate by
notice in writing to the holder at the address of the holder appearing on the
books of the Company), upon payment (i) in cash or by check acceptable to the
Company, (ii) by cancellation by the holder of indebtedness of the Company to

above, and the person entitled to receive the shares of Common Stock issuable
upon such exercise shall be treated for all purposes as the holder of record of
such shares as of the close of business on such date. As promptly as practicable
on or after such date and in any event within ten (10) days thereafter, the
Company at its expense shall issue and deliver to the person or persons entitled
to receive the same a certificate or certificates for the number of shares
issuable upon such exercise. In the event that this Warrant is exercised in
part, the Company at its expense will execute and deliver a new Warrant of like
tenor exercisable for the number of shares for which this Warrant may then be
exercised.

   6. No Fractional Shares or Scrip.  No fractional shares or scrip
      -----------------------------

entitled, the Company shall make a cash payment equal to the Exercise Price
multiplied by such fraction.

   7. Replacement of Warrant.  On receipt of evidence reasonably satisfactory

and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and substance to the Company or, in
the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense shall execute and deliver, in lieu of this Warrant, a new
warrant of like tenor and amount.

   8. Rights Of Stockholders.
      ---------------------- 

      (a) The holder of this Warrant shall not be entitled to vote or receive
dividends or be deemed the holder of Common Stock or any other securities of the
Company that may at any time be issuable on the exercise hereof for any purpose,
nor shall anything contained herein be construed to confer upon the holder, as
such, any of the fights of a stockholder of the Company or any fight to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action (whether
upon any recapitalization, issuance of stock, reclassification of stock,
consolidation,

                                       5

merger or otherwise) or to receive notices of meetings, or to receive dividends
or subscription rights or otherwise until the Warrant shall have been exercised
and the shares of Common Stock purchasable upon the exercise hereof shall have
been issued, as provided herein.

   9. Compliance with Securities Laws.
      ------------------------------- 

      (a) The holder of this Warrant, by acceptance hereof, acknowledges that
the shares of Common Stock to be issued upon exercise hereof are being acquired
solely for the holder's own account and not as a nominee for any other party,
and for investment, and that the holder will not offer, sell or otherwise
dispose of any shares of Common Stock to be issued upon exercise hereof, except
under circumstances that will not result in a violation of the United States
Securities Act of 1933, as amended (the "Act"), or any foreign or state
securities laws. Upon exercise of this Warrant, the holder shall, if requested
by the Company, confirm in writing, in a form reasonably satisfactory to the
Company, that the shares of Common Stock so purchased are being acquired solely
for the holder's own account and not as a nominee for any other party, for
investment, and not with a view toward distribution or resale.

      (b) All shares of Common Stock issued upon exercise hereof may be stamped
or imprinted with one or more of the following legends (in addition to any
legend required by the Act or the securities laws of any state of the United
States) as determined by counsel for the Company:

     THESE SHARES HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES
     ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
     HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH
     RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL
     SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

      (c) The holder of this Warrant by acceptance hereof agrees that the
transfer of the shares of Common Stock issuable upon the exercise of all or any
portion of this Warrant (the "Securities") is subject to the provisions of this
Warrant, which may include restrictions on transfer of the Securities.

   10. Reservation of Stock.  The Company covenants that during the term this
       --------------------                                                  
Warrant is exercisable, the Company shall reserve from its authorized and
unissued shares of Common Stock a sufficient number of shares to provide for the
issuance of Common Stock upon the exercise of this Warrant and, from time to
time, will take all steps necessary to amend its Certificate of Incorporation
(the "Certificate") to provide a sufficient reserve of shares of Common Stock
issuable upon exercise of this Warrant. The Company further covenants that all
shares that may be issued upon the exercise of this Warrant, upon such exercise
and payment of the Exercise Price therefor, all as set forth herein, shall be
free from all taxes, liens and charges in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously or otherwise
specified herein).  The Company agrees that its issuance of this Warrant shall
constitute full authority to its officers who are charged with the duty of
executing

                                       6
<PAGE>
 
stock certificates to execute and issue the necessary certificates for shares of
Common Stock upon the exercise of this Warrant.

   11.  Governing Law.  This Warrant shall be governed by, and construed in
        -------------                                                      
accordance with, the laws of the State of California, as such laws are applied
to contracts entered into and performed in such State, without resort to that
State's conflict-of-laws rules.

   12.  Attorney's Fees.  If any action at law or in equity is necessary to
        ---------------                                                    
enforce or interpret the terms of this Warrant, the prevailing party shall be
entitled to reasonable attorneys' fees, costs and disbursements, in addition to
any other relief to which such party may be entitled.

     IN WITNESS WHEREOF, GEOCITIES has caused this Warrant to be executed by its
officers thereunto duly authorized.

         ------------------------                                         
Initiating Holders a written request that the Company effect any registration
with respect to at least twenty percent (20%) of their Registrable Securities,
or any lesser percentage if the reasonably anticipated aggregate receipts to the
Company, net of underwriting discounts and commissions, would exceed $2,000,000,
the Company will:

          (i)  promptly give written notice of the proposed registration,
qualification or compliance to all other Holders; and

          (ii) as soon as practicable, use its best efforts to effect such
registration, qualification or compliance (including, without limitation,
appropriate qualification under applicable blue sky or other state securities
laws and appropriate compliance with applicable regulations issued under the
Securities Act and any other governmental requirements or regulations) as may be
so requested and as would permit or facilitate the sale and distribution of all
or such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request received
by the Company within twenty (20) days after receipt of such written notice from
the Company; provided, however, that the Company shall not be obligated to take
             --------- ------- 
any action to effect any such registration, qualification or compliance pursuant
to this Section 1.2.

     (A) In any particular jurisdiction in which the Company would be required
to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already subject
to service in such jurisdiction and except as may be required by the Securities
Act;

     (B) At any time prior to January 1, 1998;

     (C) Within ninety (90) days following the determination of the Board of
Directors of the Company to file a registration statement pertaining to
securities of the Company (other than (i) a registration of securities in a Rule
145 transaction, (ii) a registration statement on Form S-4 or S-8 or any form
substituting therefor or (iii) with respect to an employee benefit plan),
provided that the Company is then actively employing in good faith all
reasonable efforts to cause such registration statement to become effective;

     (D) After the Company has effected two such registrations pursuant to this
Section 1.2(a), any such registration being deemed to be effective when sixty-
six and two-thirds percent (66-2/3%) of all Registrable Securities for which
registration has been requested have been so registered;

                                      -4-
<PAGE>
 
         (E) If the Company shall furnish to such Holders a certificate signed
by the President of the Company stating that in the good faith judgment of the
Board of Directors it would be seriously detrimental to the Company or its
Holders for a registration statement to be filed in the near future, then the
Company's obligation to use its best efforts to register, qualify or comply
under this Section 1.2 shall be deferred for a period not to exceed ninety (90)
days from the date of receipt of written request from the Initiating Holders,
provided that the Company may not use this right more than once in any twelve
month period; or

         (F) Within two hundred and seventy (270) days of the effective date of
any prior registered offering of the Company's securities (other than (i) a
registration of securities in a Rule 145 transaction, (ii) a registration
statement on Form S-4 or S-8 or any form substituting therefor or (iii) with
respect to an employee benefit plan).

         Subject to the foregoing clauses (A) through (F), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable, after receipt of the request or
requests of the Initiating Holders.

         (b) Underwriting. In the event that a registration pursuant to this
             ------------                                                   
Section 1.2 is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the notice given pursuant to
Section 1 .2(a)(i). In such event, the right of any Holder to participate in
such registration shall be conditioned upon such Holder's participation in the
underwriting arrangements required by this Section 1.2, and the inclusion of
such Holder's Registrable Securities in the underwriting to the extent requested
shall be limited to the extent provided herein.

          The Company shall (together with all Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter selected for such underwriting
by a majority in interest of the Initiating Holders, but subject to the
Company's reasonable approval. Notwithstanding any other provision of this
Section 1.2, if the managing underwriter advises the Initiating Holders in
writing that marketing factors require a limitation of the number of shares to
be underwritten, then the Company shall so advise all participating Holders and
the number of shares of Registrable Securities that may be included in the
registration and underwriting shall be allocated among all Holders thereof in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities held by such Holders at the time of filing the registration
statement. No Registrable Securities excluded from the underwriting by reason of
the underwriter's marketing limitation shall be included in such registration.
To facilitate the allocation of shares in accordance with the above provisions,
the Company or the underwriters may round the number of shares allocated to any
Holder to the nearest 100 shares.

         If the underwriter has not limited the number of Registrable Securities
to be underwritten, the Company may include securities for its own account (or
for the account of other purchasers) in such registration if the managing
underwriter so agrees and if the number of Registrable Securities that would
otherwise have been included in such registration and underwriting will not
thereby be limited.

     1.3 Company Registration
         --------------------

     (a) Notice of Registration. If at any time or from time to time the
         --------- ------------                                         
Company shall determine to register any of its securities, either for its own
account or the account of a security holder or holders, other than (i) a
registration of securities in a Rule 145 transaction, (ii) a registration
statement on Form S-4 or S-8 or any form substituting therefor or (iii) with
respect to an employee benefit plan, the Company will:

         (i)  promptly give to each Holder written notice thereof, and

         (ii) include in such registration (and any related qualification under
blue sky laws or other compliance), and in any underwriting involved therein,
all the Registrable Securities specified in a written request or requests, made
within twenty (20) days after receipt of such written notice from the Company,
by any Holder.

     (b)  Underwriting. If the registration of which the Company gives notice is
          ------------                                                          
for a registered public offering involving an underwriting, the Company shall so
advise the Holders as a part of the written notice given pursuant to Section 1
 .3(a)(i). In such event the right of any Holder to registration pursuant to
Section 1.3 shall be conditioned upon such Holder's participation in such
underwriting to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company and
the other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the managing underwriter
selected for such underwriting by the Company, but subject to the reasonable
approval of Holders holding a majority in interest of the Registrable Securities
to be included in such registration. Notwithstanding any other provision of this
Section 1.3, if the managing underwriter determines that marketing factors
require limitation of the number of shares to be underwritten, the managing
underwriter may limit the Registrable Securities to be included in such
registration. The Company shall so advise all Holders and other holders
distributing their securities through such underwriting and the number of shares
of securities that may be included in the registration and underwriting (other
than on behalf of the Company) shall be allocated among all Holders and such
other holders (provided that such other holders have contractual rights to
participate in such registration which are not subordinate to the Holders) in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities or other securities requested to be included in such registration by
such Holders and such other holders; provided, however, in no event shall the
                                     --------- -------                       
amount of Registrable Securities of the Holders included in the offering be
reduced below thirty percent (30%) of the total amount of securities included in
such offering, unless such offering is the initial public offering of the
Company's securities in which case the Holders may be excluded entirely if the
managing underwriter makes the determination described above or the Holders
holding a majority of the Registrable Securities consent in writing to such a
reduction. To facilitate the allocation of shares in accordance with the above
provisions, the Company may round the number of shares allocated to any Holder
or holder to the nearest 100 shares. If any Holder or holder disapproves of the
terms of any such underwriting, he may elect to withdraw therefrom by written
notice to the Company and the managing underwriter. Any securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration, and
shall not be transferred in a public distribution prior to ninety (90) days
after the effective date of 

                                      -6-
<PAGE>
 
the registration statement relating thereto, or such other shorter period of
time as the underwriters may require.

     (c)  Registration Rights of,Founders, Officers, Directors and Employees.
          ------------------------------------------------------------------  
Upon any sale by the Company of shares of its Common Stock to the public in a
firmly underwritten public offering, the Founders and any other officer or
director designated by the Company's Board of Directors by unanimous vote shall
be entitled to include any of their shares of Common Stock in any registration
by the Company under this subsection 1.3, if such persons who choose to include
any of their securities in such registration shall continue to serve the Company
as officer or director on the effective date of such registration statement, and
such persons agree to be bound by all other provisions of this Agreement and
participate in any such registration on the same basis as each Holder in
accordance with all applicable provisions of this Agreement (such persons are
collectively referred to as "Employee-Holders").

     1.4 Registration on Form S-3.
         -------------------------

     (a)  If any Holder or Holders holding in the aggregate not less than five
percent (5%) of the then outstanding Registrable Securities request that the
Company file a registration statement on Form S-3 (or any successor form to Form
S-3) for a public offering of shares of the Registrable Securities the
reasonably anticipated aggregate price to the public of which, net of
underwriting discounts and commissions, would exceed $500,000, and the Company
is a registrant entitled to use Form S-3 to register the Registrable Securities
for such an offering, the Company shall use its best efforts to cause such
Registrable Securities to be registered for the offering on such form and to
cause such Registrable Securities to be qualified in such jurisdictions as the
Holder or Holders may reasonably request; provided, however, that the Company
                                          --------- -------                  
shall not be required to effect more than two (2) registrations pursuant to this
Section 1.4 in any twelve (12) month period. The substantive provisions of
Section 1.2(b) shall be applicable to each registration initiated under this
Section 1.4.

     (b)  Notwithstanding the foregoing, the Company shall not be obligated to
take any action pursuant to this Section 1.4:

          (i)  in any particular jurisdiction in which the Company would be
required to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already subject
to service in such jurisdiction and except as may be required by the Securities
Act;

          (ii) if the Company, within ten (10) days of the receipt of the
request of the Initiating Holders, gives notice of its bona fide intention to
effect the filing of a registration statement with the Commission within sixty
(60) days of receipt of such request (other than (x) a registration of
securities in a Rule 145 transaction, (y) a registration statement on Form S-4
or S-8 or any form substituting therefor or (z) with respect to any employee
benefit plan);

                                      -7-
<PAGE>
 
          (iii) within one hundred eighty (180) days of the effective date of
any registration referred to in Sections 1.2 and 1.3 above, provided that the
Company is actively employing in good faith all reasonable efforts to cause such
registration statement to become effective; or

          (iv) if the Company shall furnish to such Holder a certificate signed
by the President of the Company stating that in the good faith judgment of the
Board of Directors it would be seriously detrimental to the Company or the
Investors for registration statements to be filed in the near future, then the
Company's obligation to use its best efforts to file a registration statement
shall be deferred for a period not to exceed sixty (60) days from the receipt of
the request to file such registration by such Holder, provided that the Company
may not use this right more than once in any twelve month period and may not
during such sixty (60) day period file or prepare to file a registration
statement other than one provided for in this Section 1.4 or under Section 1.2
(if requested by the same Holder or Holders who have requested registration of
Registrable Securities under this Section 1.4).

     1.5  Limitations on Subsequent Registration Rights.  From and after the
          ---------------------------------------------                     
date hereof, without the approval of the holders of a majority of the
Registrable Securities, the Company shall not enter into any agreement granting
any holder or prospective holder of any securities of the Company registration
rights superior to those of the Investors. Upon obtaining such approval, the
Company will grant the Investors any rights of first refusal or registration
rights granted to subsequent purchasers of the Company's equity securities to
the extent such subsequent rights are superior, in the good faith judgment of
the Company's Board of Directors, to those rights granted in connection with the
issuance of the Series A Preferred Stock, Series B Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock or Series F Preferred Stock to the
Investors. Nothing in this Section 1.5 shall be deemed to restrict the Company's
right to grant registration rights to individual Employee-Holders pursuant to
Section 1.3(c) above, or registration rights to other purchasers of the
Company's securities that are on parity with or inferior to those registration
rights granted to the Investors.

     1.6  Expenses of Registration.  All Registration Expenses incurred in 
          ------------------------
connection with all registrations pursuant to Sections 1.2 and 1.3 and for the
first four registrations pursuant to Section 1.4 shall be borne by the Company,
provided, however, that if in order to effect a registration under Section 1.2
the Company would be required to undergo a special audit, the Holders shall bear
any expenses incurred by the Company for such special audit in excess of
$15,000. Unless otherwise stated, all Selling Expenses relating to securities
registered on behalf of the Holders shall be borne by the Holders of such
securities pro rata on the basis of the number of shares so registered.

     1.7  Registration Procedures.  In the case of each registration, 
          -----------------------
qualification or compliance effected by the Company pursuant to this Section 1,
the Company will keep each Holder advised in writing as to the initiation of
each registration and as to the completion thereof At its expense the Company

other such Holder, each of its officers and directors and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of any untrue statement (or alleged untrue statement) of a
material fact contained in any registration statement, prospectus, offering
circular or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company, such Holders,
such directors, officers, persons, underwriters or control persons for any legal
or any other expenses reasonably incurred in connection with investigating,
preparing or defending any such claim, loss, damage, liability or action, in
each case to the extent, but only to the extent, that such untrue statement (or
alleged untrue statement) or omission (or alleged omission) is made in such
registration statement, prospectus, offering circular or other document in
reliance upon and in conformity with written information furnished to the
Company by an instrument duly executed by such Holder and stated to be
specifically for use therein or the preparation thereby. Notwithstanding the
foregoing, the liability of each Holder under this subsection (b) shall be
limited to the proportion of any claim, loss, damage, liability or expense which
is equal to the proportion that the public offering price of the shares sold by
such Holder under such registration statement bears to the total public offering
price of all securities sold thereunder, but not in any event to exceed the net
proceeds received by such Holder from the sale of Registrable Securities covered
by such registration statement, unless such liability arises out of or is based
on willful misconduct by such Holder.

     (c)  Each party entitled to indemnification under this Section 1.8 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further, that the failure of any Indemnified 
                     ---------------- 
Party to give notice as provided herein shall not relieve the Indemnifying Party
of its obligations under this Section 1 unless the failure to give such notice
is materially prejudicial to an Indemnifying Party's ability to defend such
action and provided further, that the Indemnifying Party shall not assume the
           -------- -------
defense for matters as to which there is a conflict of interest or separate and
different defenses. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party a release from all liability in respect to such claim or
litigation.

     (d)  If the indemnification provided for in paragraphs (a) and (b) of this
Section 1.8 is unavailable or insufficient to hold harmless an indemnified
party under such 

                                      -11-
<PAGE>
 
paragraphs in respect of any losses, claims, damages or liabilities or actions
in respect thereof referred to therein, then each indemnifying party shall, in
lieu of indemnifying such indemnified party, contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities or actions in such proportion as appropriate to reflect the relative
fault of the Company, on the one hand, and the Holders of such Registrable
Securities, on the other, in connection with the statements or omissions which
resulted in such losses, claims, damages, liabilities or actions as well as any
other relevant equitable considerations, including the failure to give any
notice under paragraph (c) of this Section 1.8. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact relates to information supplied by the
Company, on the one hand, or the Holders of such Registrable Securities, on the
other hand, and to the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Holders of Registrable Securities agree that it would not be
just and equitable if contributions pursuant to this paragraph were determined
by pro rata allocation (even if all of the Holders of such Registrable
Securities were treated as one entity for such purpose) or by any other method
of allocation which did not take account of the equitable considerations
referred to above in this paragraph. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, liabilities or
actions in respect thereof, referred to above in this paragraph, shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this paragraph, the Holders of such
Registrable Securities shall not be required to contribute any amount in excess
of the amount, if any, by which the total price at which the Common Stock sold
by each of them was offered to the public exceeds the amount of any damages
which they would have otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission. No person guilty of fraudulent
misrepresentations (within the meaning of Section 11(f) of the Securities Act),
shall be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation.

     1.9   Information by Holder.  The Holders of securities included in any
           ---------------------                                            
registration shall furnish to the Company such information regarding such
Holders, the Registrable Securities held by them and the distribution proposed
by such Holders as the Company may request in writing and as shall be required
in connection with any registration, qualification or compliance referred to in
this Section 1.

     1.10  Rule 144 Reporting.  With a view to making available the benefits of
           ------------------
certain rules and regulations of the Commission which may at any time permit the
sale of the Registrable Securities to the public without registration, after
such time as a public market exists for the Common Stock of the Company, the
Company agrees to use its best efforts to:

     (a) Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, as such Rule may be
amended from time to time, at all times after the effective date that the
Company becomes subject to the reporting requirements of the Securities Act or
the Exchange Act.

                                      -12-
<PAGE>
 
     (b) Use its best efforts to file with the Commission in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements);

     (c)  So long as an Investor or Bohnett owns any Registrable Securities to
furnish to such Investor forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
(at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents of the Company and other information in the possession of or
reasonably obtainable by the Company as such Investor or Bohnett may reasonably
request in availing itself of any rule or regulation of the Commission allowing
such Investor or Bohnett to sell any such securities without registration.

     1.11 Standoff Agreement.  Each Holder agrees in connection with the
          ------------------                                            
Company's initial public offering of the Company's securities that, upon request
of the Company or the underwriters managing any underwritten offering of the
Company's securities, not to sell, make any short sale of; loan, grant any
option for the purchase of; or otherwise dispose of any Registrable Securities
(other than those included in the registration) without the prior written
consent of the Company or such underwriters, as the case may be, for such period
of time from the effective date of such registration as is agreed upon by
holders of a majority of the outstanding capital stock of the Company; provided,
that the officers and directors of the Company who own stock of the Company and
any shareholder holding more than five percent (5%) of the outstanding voting
securities of the Company also agree to such restrictions.

     1.12 Termination.  Any registration rights granted pursuant to this Section
          -----------
1 shall terminate with respect to any Holder at such date when all remaining
Registrable Securities held or entitled to be held by such Holder may be sold
under Rule 144 during any three (3) month period.

        2.1 Right of First Refusal.  Subject to Section 6.3 of this Agreement,
            ---------------------- 
the Company hereby grants to each Investor and each Founder (provided the

hereinafter, the "Rights Holders") the right of first refusal to purchase, pro
rata all or any part of New Securities (as defined in this Section 2.1) which
the Company may, from time to time, propose to sell and issue. For purposes of
this right of first refusal, a pro rata share for an Investor is the ratio that
the number of shares of Conversion Stock then held by such Investor bears to the
sum of the total number of shares of Conversion Stock and Common Stock held by
the Rights Holders then outstanding, and purchase, pro rata share for a Founder
is the ratio that the number of shares of Common Stock or Conversion Stock held
by such Founder bears to the sum of the total number of shares of Conversion
Stock and Common Stock held by the Rights Holders then outstanding.

        (a) "Equity Securities" shall mean any securities having voting rights
in the election of the Board of Directors not contingent upon default, or any
securities evidencing an ownership interest in the Company, or any securities
convertible into or exercisable for any shares of the foregoing, or any
securities issuable pursuant to any agreement or commitment to issue any of the
foregoing.

        (b)  Except as set forth below, "New Securities" shall mean any Equity
Securities, whether now authorized or not, and rights, options or warrants to
purchase said Equity Securities. Notwithstanding the foregoing, "New Securities"
does not include (i) options granted and options reserved for grant to officers,
directors, employees or consultants of the Company and its subsidiaries to
purchase up to 1,777,500 shares of Common Stock in the aggregate either pursuant
to any stock plan approved by the Company's Board of Directors or as otherwise
approved by the Company's Board of Directors, (ii) stock options granted to CMG
@Ventures prior to the date of this Agreement to purchase up to 500,000 shares
of Common Stock, (iii) stock options granted to Bohnett and to certain other
founders of the Company designated by Bohnett prior to the date of this
Agreement to purchase up to 500,000 shares of Common Stock, (iv) securities
offered pursuant to a Qualified Public Offering, (v) securities issued pursuant
to the acquisition of another corporation by the Company by merger, purchase of
substantially all of the assets or other reorganization whereby the Company or
its purchasers own not less than fifty-one (51%) percent of the voting power of
the surviving or successor corporation, (vi) the Conversion Stock reserved for
issuance on the date of this Agreement, (vii) a warrant or warrants for the
purchase of shares of capital stock of the Company (and stock issued upon
exercise of such warrant or warrants) which have been unanimously approved by
the Board of Directors of the Company and issued in connection with an equipment
lease, equipment financing or bank line financing, including without limitation
a warrant to purchase up to 33,898 shares of Series D Preferred Stock issued by
the Company to Cupertino Bank and a warrant to purchase up to 44,444 shares of
Common Stock issued or to be issued by the Company to Comerica Bank, (viii)
stock issued pursuant to any rights or agreements including, without limitation,
convertible securities, options and warrants, provided that the right of first
refusal established by this Section 2 applies with respect to the initial sale
or grant by the Company of such rights or agreements, or (ix) stock issued in
connection with any stock split, stock dividend or recapitalization by the
Company.

                                      -14-
<PAGE>
 
        (c)  In the event the Company proposes to undertake an issuance of New
Securities, it shall give each Rights Holder written notice of its intention,
describing the type of New Securities, and the price and terms upon which the
Company proposes to issue the same. Each Rights Holder shall have fifteen (15)
days from the date of receipt of any such notice to agree to purchase up to its
respective pro rata share of such New Securities for the price and upon the
applicable terms specified in the notice by giving written notice to the Company
and stating therein the quantity of New Securities to be purchased.

        (d)  In the event a Rights Holder fails to exercise the right of first
refusal within said fifteen (15) day period, the Company shall have one hundred
twenty (120) days thereafter to sell or enter into an agreement (pursuant to
which the sale of New Securities covered thereby shall be closed, if at all,
within sixty (60) days from the date of said agreement) to sell the New
Securities not elected to be purchased by Rights Holders at the price and upon
the terms no more favorable to the purchasers of such securities than specified
in the Company's notice. In the event the Company has not sold the New
Securities within said one hundred twenty (120) day period (or sold and issued
New Securities in accordance with the foregoing within sixty (60) days from the
date of said agreement), the Company shall not thereafter issue or sell any New
Securities, without first offering such securities in the manner provided above.

        (e)  The right of first refusal granted under this Agreement shall
expire upon the closing of the first firm commitment underwritten offering of
the Company's securities to the public pursuant to an effective registration
statement under the Securities Act.

        (f)  The Rights Holders hereby waive their rights of first offer,
including notice provisions thereof, set forth in Section 2 of the Existing
Rights Agreement with respect to the issuance of the Series E Preferred Stock
and the Series F Preferred Stock pursuant to the Stock Purchase Agreement.

     3. Rights Upon Transfer by Founders.  Each Founder hereby agrees as 
        ----------------------------------------------------------------
follows: 
- -------

        3.1  Notice of Proposed Transfer.  Before any Founder may effect any
             ---------------------------                                    
Transfer of any Stock (the "Offered Stock"), such Founder (the "Selling
Founder") must give at the same time to the Company and to the Investors a
written notice signed by the Founder (the "Selling Founder's Notice") stating
(a) the Selling Founder's bona fide intention to transfer such Offered Stock;
(b) the number of shares of the Offered Stock; (c) the name, address and
relationship, if any, to the Founder of each proposed purchaser or other
transferee; and (d) the bona fide cash price or, in reasonable detail, other
consideration, per share for which the Selling Founder proposes to transfer such
Offered Stock (the "Offered Price"). The Selling Founder's Notice shall further
state (i) that the Company may acquire, in accordance with the provisions of
this Agreement, any of the Offered Stock for the Offered Price and upon the
other terms and conditions set forth therein, (ii) that if the Company does not
purchase all of the Offered Stock then the Investors may acquire such Offered
Stock not previously purchased (the "Refused Stock") upon the same terms and
conditions and (iii) if all such Offered Stock is not purchased by the Company
and the Investors, the Investors may exercise their rights under Section 3.3

                                      -15-
<PAGE>
 
hereof. Upon the request of the Company, or any Investor, the Founder will
promptly furnish such information to the Company and to the Investors, as may be
reasonably requested to establish that the offer and proposed transferee are
bona fide.

     3.2 Right of First Refusal.
         ----------------------                             

         (a) Company's Right.  Pursuant to this Agreement, the Company and its
             ---------------                                                  
assignees shall have the right of first refusal to purchase all or any part of a
Founder's Offered Stock, if the Company gives written notice of the exercise of
such right to a Selling Founder within thirty (30) days (the "Company's Refusal
Period") after the date of the Selling Founder's Notice to the Company.

         (b)  Investors' Right.  If the Company does not intend to fully 
              ----------------     
exercise its right of first refusal referred to in subsection 3.2(a) above or if
the Company is not lawfully able to repurchase the Offered Stock, the Company
will send written notice thereof (the "Company's Expiration Notice") to the
Investors, at least ten (10) days before the expiration of the Company's Refusal
Period. The Company's Expiration Notice will specify the amount of the Refused
Stock. In such event, each Investor will have the right of first refusal to
purchase its pro rata share of the Refused Stock. For purposes of this paragraph
(b), an Investor's pro rata share is the ratio that the number of shares of
Conversion Stock then held by such Investor bears to the sum of the total number
of shares of Conversion Stock then held by all Investors. The Investors shall
have a right of oversubscription such that if any Investor declines to purchase
its pro rata share of Refused Stock, the other Investors shall, among them, have
the right to purchase up to the balance of the Refused Stock not so purchased.
Such right of oversubscription may be exercised by an Investor by accepting the
offer of the Refused Stock as to more than its pro rata share. If as a result
thereof such oversubscriptions exceed the total amount of Refused Stock
available in respect of such oversubscription privilege, the oversubscribing
Investors shall be cut back with respect to their oversubscriptions on a pro
rata basis in accordance with their respective pro rata shares or as they may
otherwise agree among themselves.

          If an Investor desires to exercise its right of first refusal to
purchase Refused Stock, such Investor must, within the fifteen (15) day period
(the "Investor Refusal Period") commencing on the date of the Company's
Expiration Notice, give written notice to the Selling Founder and to the Company
of such Investor's election to purchase an amount of the Refused Stock,
indicating the number of shares that such Investor desires to purchase, and if
such Investor desires to exercise a right of oversubscription.

         (c)  Purchase Price.  The purchase price for the Offered Stock to be
              --------------                                                 
purchased by the Company or for the Refused Stock to be purchased by an Investor
exercising its right of first refusal under this Agreement will be the Offered
Price, but will be payable as set forth in Section 3.2(d) hereof If the Offered
Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration will be determined by the Board of Directors of the
Company in good faith, which determination will be binding upon the Company, the
Investors and the Selling Founder absent fraud or error.

                                      -16-
<PAGE>
 
          (d) Payment.  Payment of the purchase price for the Offered Stock
              -------                                                      
purchased by the Company or for the Refused Stock to be purchased by an Investor
exercising its right of first refusal will be made within seven (7) days after
the date of the last day of the Investor Refusal Period. Payment of the purchase
price will be made, at the option of the Company or, as the case may be, by the
exercising Investor(s) (i) in cash (by cashier's check or wire transfer), (ii)
by cancellation of all or a portion of any outstanding indebtedness of the
Selling Founder to the Company or the Investors, as the case may be or (iii) by
any combination of the foregoing.

          (e)  Rights as a Shareholder.  If the Company and/or the Investor(s)
               -----------------------     
exercise their rights of first refusal to purchase all of the Offered Stock,
then, upon the date the notice of such exercise is given by the Company, the
Selling Founder will have no further rights as a holder of such Offered Stock
with respect to which a right of first refusal has been exercised, except the
right to receive payment for such Offered Stock from the Company and/or the
Investors(s), as the case may be, in accordance with the terms of this
Agreement, and the Selling Founder will forthwith cause all certificate(s)
evidencing such Offered Stock to be surrendered to the Company for cancellation,
and, as to purchase by the Investor(s), for transfer to the Investor(s).

          (f)  Selling Founder's Right to Transfer. If the Company and/or the 
               -----------------------------------     
Investors have not elected to purchase all of the Offered Stock, then, subject
to the Right of Co-Sale, the Selling Founder may transfer the Offered Stock
permitted to be sold by the Selling Founder, to any person named as a purchaser
or other transferee in the Selling Founder's Notice, at the Offered Price or at
a higher price, provided that such transfer (i) is consummated within ninety
(90) days after the date of the Selling Founder's Notice and (ii) is in
accordance with all the terms of this Agreement. If the Offered Stock is not so
transferred during such 90 day period, then the Selling Founder may not transfer
any of such Offered Stock without complying again in full with the provisions of
this Agreement.

          3.3  Right of Co-Sale.
               ---------------- 

          (a)  The Right.  In the event that a Founder proposes to sell shares
               ---------                 
of stock of the Company ("Founder Equity Securities"), the Investors shall have
the right, exercisable upon written notice to the Founder within thirty (30)
days after notice by the Company of such proposed sale, to participate in such
sale of securities pursuant to the specified terms and conditions of the notice,
subject to the following limitations. The Company shall provide written notice
to the Investors within thirty (30) days after receiving the notice of the
proposed transfer from the Founder. The notice to the Investors shall state the
terms of the proposed transfer and the date of expiration of the Investors'
rights hereunder. Each Investor shall be entitled to sell the same percentage of
the total number of shares of Conversion Stock then held by such Investor as the
percentage of aggregate holdings of Founder Equity Securities represented by the
Founder Equity Securities proposed to be sold by the Founder. For example, if
the Founder proposes to sell 25% of his aggregate holdings of Founder Equity
Securities, then each Investor shall be entitled to sell up to 25% of the
Conversion Stock then held by such Investor.

          (b)  Prohibited Transfers. In the event a Founder should sell any 
               --------------------     
Founder Equity Securities in contravention of the participation rights of the
Investors under this Section 3 

                                      -17-
<PAGE>
 
(a "Prohibited Transfer"), each Investor shall have the option (the "Put
Option") to sell to the Founder a number of shares equal to the number of shares
that such Investor would have had the right to sell in connection with the
Prohibited Transfer, had the Founder complied with Section 3, subject to the
following terms and conditions:

          (i)   The price per share at which such shares are to be sold to the
Founder shall be equal to the price per share paid by the third-party purchaser
or purchasers.

          (ii)  Such Investor shall deliver to the Founder, within ninety (90)
days after it has received notice from the Founder or otherwise become aware of
the Prohibited Transfer, the certificate or certificates representing the shares
to be sold, each certificate to be properly endorsed for transfer.

          (iii) The Founder shall, upon receipt of the certificates for the
repurchased shares, pay the aggregate purchase price therefor, by certified
check or bank draft made payable to the order of such Investor and shall
reimburse such Investor for any additional expenses, including legal fees and
expenses, incurred in effecting such purchase and resale.

     (c) Limitations on Rights.  Sections 3.2 and 3.3 shall not apply to a sale,
         ---------------------                                            
assignment or transfer of Founder Equity Securities:

         (i)   to the Founder's spouse, parents, grandparents, siblings,
children or grandchildren or other members of the Founder's family (including

         (iii) to the Company or the Investors pursuant to the exercise of any
right of first refusal; or

         (iv)  with respect to the right of co-sale, transfers of up to fifteen
percent (15%) of the Founder Equity Securities held by such Founder on a
cumulative basis (for purposes of this subsection (iv), shares held and/or sold
by the Founder shall include all shares held and/or sold by transferees of the
Founder pursuant to subsection (i)); provided, however, that any transferees
                                     --------- -------          
pursuant to subsections (i) or (ii) above shall receive and hold such shares
subject to the provisions of this Section 3 and there shall be no further
transfer of such shares except in accordance herewith.

     3.4 Waiver.  The Company and the Existing Investors hereby waive their
         ------                                                            
rights of first refusal and the rights of co-sale, including the notice
provisions thereof; set forth in Section 3 of the Existing Rights Agreement,
with respect to the sale and transfer of any Stock owned by any Founder (defined
in Section 3 hereof as "Offered Stock" or "Founder Equity Securities") pursuant
to the Stock Purchase Agreement.

     3.5 Stock Legend.  All certificates representing shares of Common Stock 
         ------------
of the Company held by the Founders and transferees described in this Section 3
above shall bear 

                                      -18-

              ---------------------      
not to amend or waive the voting or other provisions of the Company's Articles
of Incorporation, By-laws or this Agreement if such amendment or waiver would
cause any Regulated Holder to have a Regulatory Problem (as defined in the Small
Business Sideletter) that arises out of an increase in the voting power or
control of such Regulated Holder as a result of such amendment or waiver,
provided that any such Shareholder notifies the Company that it would have a
Regulatory Problem promptly after it has notice of such amendment or waiver.

     7.   Miscellaneous.
          ------------- 

          7.1 Governing Law.  This Agreement shall be governed in all respects
              -------------

              ---------------------------  
and entire understanding and agreement between the parties with regard to the
subjects hereof; and no party shall be liable or bound to any other party in any

of (i) Investors holding at least two-thirds (2/3) of the Conversion Stock

Preferred Stock subject to this Agreement, (ii) Investors holding at least
eighty percent (80%) of the Conversion Stock issued or issuable upon conversion

                                      -20-
<PAGE>
 
authorized by resolution of its Board of Directors, may enter into a
supplementary agreement for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of this Agreement; provided,
however, that no such modification, amendment or waiver shall reduce the
aforesaid percentages of any Series or combination of Series of Preferred Stock
or Equity Securities held by Investors or Founders needed for a modification,
waiver or amendment pursuant to this Section 7.4 without the consent of all of
the Investors or the Founders, as the case may be. Upon the effectuation of each
such waiver, consent, agreement or amendment or modification, the Company shall
promptly give written notice thereof to the record holders of the Registrable
Securities who have not previously consented thereto in writing. This Agreement
or any provision hereof may be changed, waived, discharged or terminated only by
a statement in writing signed by the party against which enforcement of the
change, waiver, discharge or termination is sought, except to the extent
provided in this Section 7.4.

          7.5 Notices, etc.  All notices and other communications required or
              ------------

addresses or to their telecopier numbers as shown on Schedule I hereto, or at
such other addresses or facsimile numbers as the Shareholders shall have
furnished to the Company in writing and (b) in the case of the Company, at its
address set forth at the beginning of this Agreement, or at such other address
or facsimile number as the Company shall have furnished to the Investors in
writing. Notices that are mailed shall be deemed received five (5) days after
deposit in the United States mail.

          7.6 Delay or Omissions.  Except as expressly provided herein, no 
              ------------------
delay or omission to exercise any right, power or remedy accruing to any
Shareholder, upon any breach or default of the Company under this Agreement,
shall impair any such right, power or remedy of such holder nor shall it be
construed to be a waiver of any such breach or default, or an acquiescence
therein, or of or in any similar breach or default thereafter occurring; nor
shall any waiver of any single breach or default be deemed a waiver of any other
breach or default theretofore or thereafter occurring. Any waiver, permit,
consent or approval of any kind or character on the part of any holder of any
breach or default under this Agreement, or any waiver on the part of any holder
of any provisions or conditions of this agreement, must be in writing and shall
be effective only to the extent specifically set forth in such writing. All
remedies, either under this Agreement or by-law or otherwise afforded to any
holder, shall be cumulative and not alternative.

              ------------
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

          7.8 Severability.  If any provision of this Agreement, or the 
              ------------
application thereof, shall for any reason and to any extent be invalid or
unenforceable the remainder of this Agreement and application of such provision
to persons or circumstances shall be interpreted so as best to reasonably effect
the intent of the parties hereto, the parties further agree to replace such void
or unenforceable provision of this Agreement with a valid and enforceable
provision 

                                      -21-
<PAGE>
 
which will achieve to the extent possible, the economic, business and other
purposes of the void or unenforceable provision.

          7.9  Titles and Subtitles.  The titles and subtitles used in this 
               --------------------
Agreement are used for convenience only and are not considered in construing or
interpreting this Agreement.

          7.10 Stock Option Agreements.  The Investors and the Company agree 
               -----------------------
that, with respect to the rights granted in favor of the holders of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock to purchase shares of the Company's Common Stock under certain
circumstances as holders of "Senior Securities," which such term is defined and
which such rights are set forth in the Stock Option Agreements between the
Company and certain of its employees, officers, directors, consultants and
shareholders, respectively, "Senior Securities" shall be deemed to mean the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock,
Series D Preferred Stock, Series E Preferred Stock, Series F Preferred Stock and
any additional series of the Company's Preferred Stock that may be issued

have been granted in favor of the holders of all such series of Preferred Stock.

          The foregoing agreement is hereby executed as of the date first above
written.

                           INDEMNIFICATION AGREEMENT

          THIS AGREEMENT (the "Agreement") is made and entered into this ____
day of _______________, 1998 between GeoCities, a Delaware corporation (the
"Company") and ____________________ ("Indemnitee").

                                WITNESSETH THAT:

          WHEREAS, Indemnitee performs a valuable service for the Company; and

          WHEREAS, the Board of Directors of the Company have adopted a Second
Amended and Restated Certificate of Incorporation (the "Certificate") permitting
the Board of Directors to indemnify certain officers and employees designated by
the Board of Directors or Chief Executive Officer (the "Officers") and directors
(the "Directors") of the Company; and

          WHEREAS, the Certificate and Section 145 of the Delaware General
Corporation Law, as amended ("Law"), by their nonexclusive nature permit
contracts between the Company and the Officers and Directors of the Company with
respect to indemnification of such Officers and Directors; and

          WHEREAS, in accordance with the authorization as provided by the Law,
the Company may purchase and maintain a policy or policies of Directors' and
Officers' liability insurance ("D & O Insurance"), covering certain liabilities
which may be incurred by its Officers and Directors in the performance of their
obligations as Officers and Directors of the Company; and

          WHEREAS, as a result of recent developments affecting the terms, scope
and availability of D & O Insurance there exists general uncertainty as to the
extent of protection afforded the Company's Officers and Directors by such D & O
Insurance and said uncertainty also exists under statutory and bylaw
indemnification provisions; and

          WHEREAS, in recognition of past services and in order to induce
Indemnitee to continue to serve as an officer and/or a director of the Company,
the Company has determined and agreed to enter into this contract with
Indemnitee;

          NOW, THEREFORE, in consideration of Indemnitee's continued service as
an officer and/or a director after the date hereof, the parties hereto agree as
follows:

          1.  INDEMNITY OF INDEMNITEE.  The Company hereby agrees to hold
harmless and indemnify Indemnitee to the full extent authorized or permitted by
the provisions of the Law, as such may be amended from time to time, and Article
___ of the Certificate, as such may be amended. In furtherance of the foregoing
indemnification, and without limiting the generality thereof:

              (a)  Proceedings Other Than Proceedings by or in the Right of the
Company. Indemnitee shall be entitled to the rights of indemnification provided
in this Section 1(a) if, by reason of his Corporate Status (as hereinafter
defined), he is, or is threatened to be made, a party to or participant in any
Proceeding (as hereinafter defined) other than a Proceeding by
<PAGE>
 
or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall
be indemnified against all Expenses (as hereinafter defined), judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred
by him or on his behalf in connection with such Proceeding or any claim, issue
or matter therein, if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the Company and, with
respect to any criminal Proceeding, had no reasonable cause to believe his
conduct was unlawful.

              (b)  Proceedings by or in the Right of the Company. Indemnitee
shall be entitled to the rights of indemnification provided in this Section 1(b)
if, by reason of his Corporate Status, he is, or is threatened to be made, a
party to or participant in any Proceeding brought by or in the right of the
Company to procure a judgment in its favor. Pursuant to this Section 1(b),
Indemnitee shall be indemnified against all Expenses actually and reasonably
incurred by him or on his behalf in connection with such Proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Company; provided, however, that, if applicable law so
provides, no indemnification against such Expenses shall be made in respect of
any claim, issue or matter in such Proceeding as to which Indemnitee shall have
been adjudged to be liable to the Company unless and to the extent that the
Court of Chancery of the State of Delaware, or the court in which such
Proceeding shall have been brought or is pending, shall determine that such
indemnification may be made.

              (c)  Indemnification for Expenses of a Party Who is Wholly or
Partly Successful. Notwithstanding any other provision of this Agreement, to the
extent that Indemnitee is, by reason of his Corporate Status, a party to and is
successful, on the merits or otherwise, in any Proceeding, he shall be
indemnified to the maximum extent permitted by law against all Expenses actually
and reasonably incurred by him or on his behalf in connection therewith. If
Indemnitee is not wholly successful in such Proceeding but is successful, on the
merits or otherwise, as to one or more but less than all claims, issues or
matters in such Proceeding, the Company shall indemnify Indemnitee against all
Expenses actually and reasonably incurred by him or on his behalf in connection
with each successfully resolved claim, issue or matter. For purposes of this
Section and without limitation, the termination of any claim, issue or matter in
such a Proceeding by dismissal, with or without prejudice, shall be deemed to be
a successful result as to such claim, issue or matter.

          2.  ADDITIONAL INDEMNITY.
              -------------------- 

              (a)  Subject only to the exclusions set forth in Section 2(b)
hereof, the Company hereby further agrees to hold harmless and indemnify
Indemnitee against any and all Expenses, judgments, fines and amounts paid in
settlement actually and reasonably incurred by Indemnitee in connection with any
Proceeding (including an action by or on behalf of the Company) to which
Indemnitee is, was or at any time becomes a party, or is threatened to be made a
party, by reason of his Corporate Status; provided, however, that with respect
to actions by or on behalf of the Company, indemnification of Indemnitee against
any judgments shall be made by the Company only as authorized in the specific
case upon a determination that Indemnitee acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Company; and

                                       2
<PAGE>
 
              (b)  No indemnity pursuant to this Section 2 shall be paid by the
Company:

                   (i)   In respect to remuneration paid to Indemnitee if it
     shall be determined by a final judgment or other final adjudication that
     such remuneration was in violation of law;

                   (ii)  On account of any suit in which judgment is rendered
     against Indemnitee for an accounting of profits made from the purchase or
     sale by Indemnitee of securities of the Company pursuant to the provisions
     of Section 16(b) of the Securities Exchange Act of 1934 and amendments
     thereto or similar provisions of any federal, state or local statutory law;

                   (iii) On account of Indemnitee's conduct which is finally
     adjudged to have been knowingly fraudulent or deliberately dishonest, or to
     constitute willful misconduct; or

                   (iv)  If a final decision by a court having jurisdiction in
     the matter shall determine that such indemnification is not lawful.

                                       3
<PAGE>
 
          3.  CONTRIBUTION.  If the indemnification provided in Sections 1 and 2
              ------------
     is unavailable and may not be paid to Indemnitee for any reason other than
     those set forth in paragraphs (i), (ii) and (iii) of Section 2(b), then in
     respect to any Proceeding in which the Company is jointly liable with
     Indemnitee (or would be if joined in such Proceeding), the Company shall
     contribute to the amount of Expenses, judgments, fines and amounts paid in
     settlement actually and reasonably incurred and paid or payable by
     Indemnitee in such proportion as is appropriate to reflect (i) the relative
     benefits received by the Company on the one hand and by the Indemnitee on
     the other hand from the transaction from which such Proceeding arose, and
     (ii) the relative fault of the Company on the one hand and of the
     Indemnitee on the other hand in connection with the events which resulted
     in such Expenses, judgments, fines or settlement amounts, as well as any
     other relevant equitable considerations. The relative fault of the Company
     on the one hand and of the Indemnitee on the other hand shall be determined
     by reference to, among other things, the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent the
     circumstances resulting in such Expenses, judgments, fines or settlement
     amounts. The Company agrees that it would not be just and equitable if
     contribution pursuant to this Section 3 were determined by pro rata
     allocation or any other method of allocation which does not take account of
     the foregoing equitable considerations.

          4.  INDEMNIFICATION FOR EXPENSES OF A WITNESS.  Notwithstanding any
              -----------------------------------------
other provision of this Agreement, to the extent that Indemnitee is, by reason
of his Corporate Status, a witness in any Proceeding to which Indemnitee is not
a party, he shall be indemnified against all Expenses actually and reasonably
incurred by him or on his behalf in connection therewith.

          5.  ADVANCEMENT OF EXPENSES.  Notwithstanding any other provision of
              -----------------------
this Agreement, the Company shall advance all reasonable Expenses incurred by or
on behalf of Indemnitee in connection with any Proceeding by reason of
Indemnitee's Corporate Status within ten days after the receipt by the Company
of a statement or statements from Indemnitee requesting such advance or advances
from time to time, whether prior to or after final disposition of such
Proceeding. Such statement or statements shall reasonably evidence the Expenses
incurred by Indemnitee and shall include or be preceded or accompanied by an
undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it
shall ultimately be determined that Indemnitee is not entitled to be indemnified
against such Expenses. Any advances and undertakings to repay pursuant to this
Section 5 shall be unsecured and interest free. Notwithstanding the foregoing,
the obligation of the Company to advance Expenses pursuant to this Section 5
shall be subject to the condition that, if, when and to the extent that the
Company determines that Indemnitee would not be permitted to be indemnified
under applicable law, the Company shall be entitled to be reimbursed, within
thirty (30) days of such determination, by Indemnitee (who hereby agrees to
reimburse the Company) for all such amounts theretofore paid; provided, however,
that if Indemnitee has commenced or thereafter commences legal proceedings in a
court of competent jurisdiction to secure a determination that Indemnitee should
be indemnified under applicable law, any determination made by the Company that
Indemnitee would not be permitted to be indemnified under applicable law shall
not be binding and Indemnitee shall not be required to reimburse the Company for
any advance of Expenses until a final judicial determination is made with
respect thereto (as to which all rights of appeal therefrom have been exhausted
or lapsed).

          6.  PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION.
              ------------------------------------------------------------- 

              (a)  To obtain indemnification (including, but not limited to, the
advancement of Expenses and contribution by the Company) under this Agreement,
Indemnitee shall submit to the Chief Executive Officer or Chief Financial
Officer a written request, including therein or therewith such documentation and
information as is reasonably available to Indemnitee and is reasonably necessary
to determine whether and to what extent Indemnitee is entitled to
indemnification. The Secretary or any Assistant Secretary of the Company shall,
promptly upon receipt of such a request for indemnification, advise the Board of
Directors in writing that Indemnitee has requested indemnification.

              (b)  Upon written request by Indemnitee for indemnification
pursuant to the first sentence of Section 6(a) hereof, a determination, if
required by applicable law, with respect to Indemnitee's entitlement thereto
shall be made in the specific case: (i) if a Change in Control (as hereinafter
defined) shall have occurred, by Independent Counsel (as hereinafter defined) in
a written opinion to the Board of Directors, a copy of which shall be delivered
to Indemnitee (unless Indemnitee shall request that such determination be made
by the Board of Directors or the stockholders, in which case the determination
shall be made in the manner provided in Clause (ii) below), or (ii) if a Change
in Control shall not have occurred, (A) by the Board of Directors by a majority
vote of a quorum consisting of Disinterested Directors (as hereinafter defined),
or (B) if a quorum of the Board of Directors consisting of Disinterested
Directors is not obtainable or, even if obtainable, said Disinterested Directors
so direct, by Independent Counsel in a written opinion to the Board of
Directors, a copy of which shall be delivered to Indemnitee, or (C) if so
directed by said Disinterested Directors, by the stockholders of the Company;
and, if it is determined that Indemnitee is entitled to indemnification, payment
to Indemnitee shall be made within ten (10) days after such determination.
Indemnitee shall cooperate with the person, persons or entity making such
determination with respect to Indemnitee's entitlement to indemnification,
including providing to such person, persons or entity upon reasonable advance
request any documentation or information which is not privileged or otherwise
protected from disclosure and which is reasonably available to Indemnitee and
reasonably necessary to such determination. Any Independent Counsel, member of
the Board of Directors, or stockholder of the Company shall act reasonably and
in good faith in making a determination under the Agreement of the Indemnitee's
entitlement to indemnification. Any costs or expenses (including attorneys' fees
and disbursements) incurred by Indemnitee in so cooperating with the person,
persons or entity making such determination shall be borne by the Company
(irrespective of the determination as to Indemnitee's entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold
Indemnitee harmless therefrom.

              (c)  If the determination of entitlement to indemnification is to
be made by Independent Counsel pursuant to Section 6(b) hereof, the Independent
Counsel shall be selected as provided in this Section 6(c). If a Change in
Control shall not have occurred, the Independent Counsel shall be selected by
the Board of Directors, and the Company shall give written notice to Indemnitee
advising him of the identity of the Independent Counsel so selected. If a Change
in Control shall have occurred, the Independent Counsel shall be selected by
Indemnitee (unless Indemnitee shall request that such selection be made by the
Board of Directors, in which event the preceding sentence shall apply), and
Indemnitee shall give written

                                       5
<PAGE>
 
notice to the Company advising it of the identity of the Independent Counsel so
selected. In either event, Indemnitee or the Company, as the case may be, may,
within 10 days after such written notice of selection shall have been given,
deliver to the Company or to Indemnitee, as the case may be, a written objection
to such selection; provided, however, that such objection may be asserted only
on the ground that the Independent Counsel so selected does not meet the
requirements of "Independent Counsel" as defined in Section 14 of this
Agreement, and the objection shall set forth with particularity the factual
basis of such assertion. Absent a proper and timely objection, the person so
selected shall act as Independent Counsel. If a written objection is made and
substantiated, the Independent Counsel selected may not serve as Independent
Counsel unless and until such objection is withdrawn or a court has determined
that such objection is without merit. If, within 20 days after submission by
Indemnitee of a written request for indemnification pursuant to Section 6(a)
hereof, no Independent Counsel shall have been selected and not objected to,
either the Company or Indemnitee may petition the Court of Chancery of the State
of Delaware or other court of competent jurisdiction for resolution of any
objection which shall have been made by the Company or Indemnitee to the other's
selection of Independent Counsel and/or for the appointment as Independent
Counsel of a person selected by the court or by such other person as the court
shall designate, and the person with respect to whom all objections are so
resolved or the person so appointed shall act as Independent Counsel under
Section 6(b) hereof. The Company shall pay any and all reasonable fees and
expenses of Independent Counsel incurred by such Independent Counsel in
connection with acting pursuant to Section 6(b) hereof, and the Company shall
pay all reasonable fees and expenses incident to the procedures of this Section
6(c), regardless of the manner in which such Independent Counsel was selected or
appointed. Upon the due commencement of any judicial proceeding or arbitration
pursuant to Section 8(a)(iii) of this Agreement, Independent Counsel shall be
discharged and relieved of any further responsibility in such capacity (subject
to the applicable standards of professional conduct then prevailing).

              (d)  The Company shall not be required to obtain the consent of
the Indemnitee to the settlement of any Proceeding which the Company has
undertaken to defend if the Company assumes full and sole responsibility for
such settlement and the settlement grants the Indemnitee a complete and
unqualified release in respect of the potential liability.

          7.  PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS.
              ---------------------------------------------- 

              (a)  In making a determination with respect to entitlement to
indemnification hereunder, the person or persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under
this Agreement if Indemnitee has submitted a request for indemnification in
accordance with Section 6(a) of this Agreement, and the Company shall have the
burden of proof to overcome that presumption in connection with the making by
any person, persons or entity of any determination contrary to that presumption.

              (b)  If the person, persons or entity empowered or selected under
Section 6 of this Agreement to determine whether Indemnitee is entitled to
indemnification shall not have made a determination within thirty (30) days
after receipt by the Company of the request therefor, the requisite
determination of entitlement to indemnification shall be deemed to have been
made and Indemnitee shall be entitled to such indemnification, absent (i) a
misstatement by Indemnitee of a material fact, or an omission of a material fact
necessary to

                                       6
<PAGE>
 
make Indemnitee's statement not materially misleading, in connection with the
request for indemnification, or (ii) a prohibition of such indemnification under
applicable law; provided, however, that such 30 day period may be extended for a
reasonable time, not to exceed an additional fifteen (15) days, if the person,
persons or entity making the determination with respect to entitlement to
indemnification in good faith requires such additional time for the obtaining or
evaluating documentation and/or information relating thereto; and provided,
further, that the foregoing provisions of this Section 7(b) shall not apply (i)
if the determination of entitlement to indemnification is to be made by the
stockholders pursuant to Section 6(b) of this Agreement and if (A) within
fifteen (15) days after receipt by the Company of the request for such
determination the Board of Directors or the Disinterested Directors, if
appropriate, resolve to submit such determination to the stockholders for their
consideration at an annual meeting thereof to be held within seventy five (75)
days after such receipt and such determination is made thereat, or (B) a special
meeting of stockholders is called within fifteen (15) days after such receipt
for the purpose of making such determination, such meeting is held for such
purpose within sixty (60) days after having been so called and such
determination is made thereat, or (ii) if the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Section 6(b) of
this Agreement.

              (c)  The termination of any Proceeding or of any claim, issue or
matter therein, by judgment, order, settlement (with or without court approval),
conviction, or upon a plea of nolo contendere or its equivalent, shall not
(except as otherwise expressly provided in this Agreement) of itself adversely
affect the right of Indemnitee to indemnification or create a presumption that
Indemnitee did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the Company or, with
respect to any criminal Proceeding, that Indemnitee had reasonable cause to
believe that his conduct was unlawful.

              (d)  For purposes of any determination of good faith, Indemnitee
shall be deemed to have acted in good faith if Indemnitee's action is based on
the records or books of account of the Enterprise (as hereinafter defined),
including financial statements, or on information supplied to Indemnitee by the
Officers and Directors of the Enterprise in the course of their duties, or on
the advice of legal counsel for the Enterprise or on information or records
given or reports made to the Enterprise by an independent certified public
accountant or by an appraiser or other expert selected with reasonable care by
the Enterprise. In addition, the knowledge and/or actions, or failure to act, of
any director, officer, agent or employee of the Enterprise shall not be imputed
to Indemnitee for purposes of determining the right to indemnification under
this Agreement. The provisions of this Section 7(d) shall not be deemed to be
exclusive or to limit in any way the other circumstances in which the Indemnitee
may be deemed to have met the applicable standard of conduct set forth in this
Agreement.

          8.  REMEDIES OF INDEMNITEE.
              ---------------------- 

              (a)  In the event that (i) a determination is made pursuant to
Section 6 of this Agreement that Indemnitee is not entitled to indemnification
under this Agreement, (ii) advancement of Expenses is not timely made pursuant
to Section 5 of this Agreement, (iii) no determination of entitlement to
indemnification shall have been made pursuant to Section 6(b) of this Agreement
within 90 days after receipt by the Company of the request for indemnification,

                                       7
<PAGE>
 
(iv) payment of indemnification is not made pursuant to Section 3 or 4 of this
Agreement within ten (10) days after receipt by the Company of a written request
therefor, or (v) payment of indemnification is not made within ten (10) days
after a determination has been made that Indemnitee is entitled to
indemnification or such determination is deemed to have been made pursuant to
Section 6 or 7 of this Agreement, Indemnitee shall be entitled to an
adjudication in an appropriate court of the State of Delaware, or in any other
court of competent jurisdiction, of his entitlement to such indemnification.
Alternatively, Indemnitee, at his option, may seek an award in arbitration to be
conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of
the American Arbitration Association. Indemnitee shall commence such proceeding
seeking an adjudication or an award in arbitration within 180 days following the
date on which Indemnitee first has the right to commence such proceeding
pursuant to this Section 8(a). The Company shall not oppose Indemnitee's right
to seek any such adjudication or award in arbitration.

              (b)  In the event that a determination shall have been made
pursuant to Section 6(b) of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to
this Section 8 shall be conducted in all respects as a de novo trial, or
arbitration, on the merits and Indemnitee shall not be prejudiced by reason of
that adverse determination.

              (c)  If a determination shall have been made pursuant to Section
6(b) of this Agreement that Indemnitee is entitled to indemnification, the
Company shall be bound by such determination in any judicial proceeding or
arbitration commenced pursuant to this Section 8, absent (i) a misstatement by
Indemnitee of a material fact, or an omission of a material fact necessary to
make Indemnitee's statement not materially misleading, in connection with the
request for indemnification, or (ii) a prohibition of such indemnification under
applicable law.

              (d)  In the event that Indemnitee, pursuant to this Section 8,
seeks a judicial adjudication of or an award in arbitration to enforce his
rights under, or to recover damages for breach of, this Agreement, Indemnitee
shall be entitled to recover from the Company, and shall be indemnified by the
Company against, any and all expenses (of the types described in the definition
of Expenses in Section 16 of this Agreement) actually and reasonably incurred by
him in such judicial adjudication or arbitration, but only if he prevails
therein. If it shall be determined in said judicial adjudication or arbitration
that Indemnitee is entitled to receive part but not all of the indemnification
sought, the expenses incurred by Indemnitee in connection with such judicial
adjudication or arbitration shall be appropriately prorated. The Company shall
indemnify Indemnitee against any and all expenses and, if requested by
Indemnitee, shall (within ten (10) days after receipt by the Company of a
written request therefor) advance such expenses to Indemnitee, which are
incurred by Indemnitee in connection with any action brought by Indemnitee to
recover under any Directors' and Officers' liability insurance policies
maintained by the Company, regardless of whether Indemnitee ultimately is
determined to be entitled to such indemnification, advancement of expenses or
insurance recovery, as the case may be.

              (e)  The Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 8 that the
procedures and presumptions of this Agreement are not valid, binding and
enforceable and shall stipulate in any 

                                       8
<PAGE>
 
such court or before any such arbitrator that the Company is bound by all the
provisions of this Agreement.

          9.  NONEXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION.
              ---------------------------------------------------------- 

              (a)  The rights of indemnification as provided by this Agreement
shall not be deemed exclusive of any other rights to which Indemnitee may at any
time be entitled under applicable law, the Certificate, any agreement, a vote of
stockholders or a resolution of Directors, or otherwise. No amendment,
alteration or repeal of this Agreement or of any provision hereof shall limit or
restrict any right of Indemnitee under this Agreement in respect of any action
taken or omitted by such Indemnitee in his Corporate Status prior to such
amendment, alteration or repeal. To the extent that a change in the Law, whether
by statute or judicial decision, permits greater indemnification than would be
afforded currently under the Certificate and this Agreement, it is the intent of
the parties hereto that Indemnitee shall enjoy by this Agreement the greater
benefits so afforded by such change. No right or remedy herein conferred is
intended to be exclusive of any other right or remedy, and every other right and
remedy shall be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other right or remedy.

              (b)  To the extent that the Company maintains an insurance policy
or policies providing liability insurance for Directors, Officers, employees, or
agents or fiduciaries of the Company or of any other corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise which such
person serves at the request of the Company, Indemnitee shall be covered by such
policy or policies in accordance with its or their terms to the maximum extent
of the coverage available for any such director, officer, employee or agent
under such policy or policies.

              (c)  In the event of any payment under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee, who shall execute all papers required and take all
action necessary to secure such rights, including execution of such documents as
are necessary to enable the Company to bring suit to enforce such rights.

              (d)  The Company shall not be liable under this Agreement to make
any payment of amounts otherwise indemnifiable hereunder if and to the extent
that Indemnitee has otherwise actually received such payment under any insurance
policy, contract, agreement or otherwise.

          10.  EXCEPTION TO RIGHT OF INDEMNIFICATION.  Notwithstanding any 
               ------------------------------------- 
other provision of this Agreement, Indemnitee shall not be entitled to
indemnification under this Agreement with respect to any Proceeding brought by
Indemnitee, or any claim therein, unless (a) the bringing of such Proceeding or
making of such claim shall have been approved by the Board of Directors or (b)
such Proceeding is being brought by the Indemnitee to assert his rights under
this Agreement.

                                       9
<PAGE>
 
          11.  DURATION OF AGREEMENT.  All agreements and obligations of the
               ---------------------
Company contained herein shall continue during the period Indemnitee is an
officer and/or a director of the Company (or is or was serving at the request of
the Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise) and shall continue
thereafter so long as Indemnitee shall be subject to any Proceeding (or any
proceeding commenced under Section 8 hereof) by reason of his Corporate Status,
whether or not he is acting or serving in any such capacity at the time any
liability or expense is incurred for which indemnification can be provided under
this Agreement. This Agreement shall be binding upon and inure to the benefit of
and be enforceable by the parties hereto and their respective successors
(including any direct or indirect successor by purchase, merger, consolidation
or otherwise to all or substantially all of the business or assets of the
Company), assigns, spouses, heirs, executors and personal and legal
representatives. This Agreement shall continue in effect regardless of whether
Indemnitee continues to serve as an officer and/or a director of the Company or
any other enterprise at the Company's request.

          12.  SECURITY.  To the extent requested by the Indemnitee and approved
               -------- 
by the Board of Directors, the Company may at any time and from time to time
provide security to the Indemnitee for the Company's obligations hereunder
through an irrevocable bank line of credit, funded trust or other collateral.
Any such security, once provided to the Indemnitee, may not be revoked or
released without the prior written consent of the Indemnitee.

          13.  ENFORCEMENT.
               -----------

               (a)  The Company expressly confirms and agrees that it has
entered into this Agreement and assumed the obligations imposed on it hereby in
order to induce Indemnitee to serve as an officer and/or a director of the
Company, and the Company acknowledges that Indemnitee is relying upon this
Agreement in serving as an officer and/or a director of the Company.

               (b)  This Agreement constitutes the entire agreement between the
parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the
parties hereto with respect to the subject matter hereof.

          14.  DEFINITIONS.  For purposes of this Agreement:
               ----------- 

               (a)  "Change in Control" means a change in control of the Company
occurring after the date of this Agreement of a nature that would be required to
be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or in
response to any similar item on any similar schedule or form) promulgated under
the Securities Exchange Act of 1934 (the "Act"), whether or not the Company is
then subject to such reporting requirement; provided, however, that, without
limitation, such a Change in Control shall be deemed to have occurred if after
the date of this Agreement (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Act, as amended) other than a trustee or other fiduciary
holding securities under an employee benefit plan of the Company or a
corporation owned directly or indirectly by the stockholders of the Company in
substantially the same proportions as their ownership of stock of the Company,
is or becomes the "beneficial owner" (as defined in Rule 13d3 under the Act),

                                      10
<PAGE>
 
directly or indirectly, of securities of the Company representing 15% or more of
the combined voting power of the Company's then outstanding securities (other
than any such person or any affiliate thereof that is such a 15% beneficial
owner as of the date hereof) without the prior approval of at least two-thirds
of the members of the Board of Directors in office immediately prior to such
person attaining such percentage interest; (ii) there occurs a proxy contest, or
the Company is a party to a merger, consolidation, sale of assets, plan of
liquidation or other reorganization, as a consequence of which members of the
Board of Directors in office immediately prior to such transaction or event
constitute less than a majority of the Board of Directors thereafter; or (iii)
during any period of two consecutive years, other than as a result of an event
described in clause (a)(ii) of this Section 16, individuals who at the beginning
of such period constituted the Board of Directors (including for this purpose
any new director whose election or nomination for election by the Company's
stockholders was approved by a vote of at least two-thirds of the Directors then
still in office who were Directors at the beginning of such period) cease for
any reason to constitute at least a majority of the Board of Directors. A Change
in Control shall not be deemed to have occurred under item (i) above if the
"person" described under item (i) is entitled to report its ownership on
Schedule 13G promulgated under the Act and such person is able to represent that
it acquired such securities in the ordinary course of its business and not with
the purpose nor with the effect of changing or influencing the control of the
Company, nor in connection with or as a participant in any transaction having
such purpose or effect. If the "person" referred to in the previous sentence
would at any time not be entitled to continue to report such ownership on
Schedule 13G pursuant to Rule 13d1(b)(3)(i)(B) of the Act, then a Change in
Control shall be deemed to have occurred at such time.

              (b)  "Corporate Status" describes the status of a person who is or
was a director, officer, employee or agent or fiduciary of the Company or of any
other corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise which such person is or was serving at the express written
request of the Company.

              (c)  "Disinterested Director" means a director of the Company who
is not and was not a party to the Proceeding in respect of which indemnification
is sought by Indemnitee.

              (d)  "Enterprise" shall mean the Company and any other
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise of which Indemnitee is or was serving at the express written request
of the Company as a director, officer, employee, agent or fiduciary.

              (e)  "Expenses" shall include all reasonable attorneys' fees,
retainers, court costs, transcript costs, fees of experts, witness fees, travel
expenses, duplicating costs, printing and binding costs, telephone charges,
postage, delivery service fees, and all other disbursements or expenses of the
types customarily incurred in connection with prosecuting, defending, preparing
to prosecute or defend, investigating, participating, or being or preparing to
be a witness in a Proceeding.

              (f)  "Independent Counsel" means a law firm, or a member of a law
firm, that is experienced in matters of corporation law and neither presently
is, nor in the past five years has been, retained to represent: (i) the Company
or Indemnitee in any matter material

                                      11
<PAGE>
 
to either such party (other than with respect to matters concerning the
Indemnitee under this Agreement, or of other indemnitees under similar
indemnification agreements), or (ii) any other party to the Proceeding giving
rise to a claim for indemnification hereunder. Notwithstanding the foregoing,
the term "Independent Counsel" shall not include any person who, under the
applicable standards of professional conduct then prevailing, would have a
conflict of interest in representing either the Company or Indemnitee in an
action to determine Indemnitee's rights under this Agreement. The Company agrees
to pay the reasonable fees of the Independent Counsel referred to above and to
fully indemnify such counsel against any and all Expenses, claims, liabilities
and damages arising out of or relating to this Agreement or its engagement
pursuant hereto.

              (g)  "Proceeding" includes any threatened, pending or completed
action, suit, arbitration, alternate dispute resolution mechanism,
investigation, inquiry, administrative hearing or any other actual, threatened
or completed proceeding, whether brought by or in the right of the Company or
otherwise and whether civil, criminal, administrative or investigative, in which
Indemnitee was, is or will be involved as a party or otherwise, by reason of the
fact that Indemnitee is or was an officer and/or a director of the Company, by
reason of any action taken by him or of any inaction on his part while acting as
an officer and/or a director of the Company, or by reason of the fact that he is
or was serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise; in each case whether or not he is acting or serving in any such
capacity at the time any liability or expense is incurred for which
indemnification can be provided under this Agreement; including one pending on
or before the date of this Agreement; and excluding one initiated by an
Indemnitee pursuant to Section 8 of this Agreement to enforce his rights under
this Agreement.

         15.  SEVERABILITY.  If any provision or provisions of this Agreement
              ------------ 
shall be held by a court of competent jurisdiction to be invalid, void, illegal
or otherwise unenforceable for any reason whatsoever: (a) the validity, legality
and enforceability of the remaining provisions of this Agreement (including
without limitation, each portion of any section of this Agreement containing any
such provision held to be invalid, illegal or unenforceable, that is not itself
invalid, illegal or unenforceable) shall not in any way be affected or impaired
thereby and shall remain enforceable to the fullest extent permitted by law; and
(b) to the fullest extent possible, the provisions of this Agreement (including,
without limitation, each portion of any section of this Agreement containing any
such provision held to be invalid, illegal or unenforceable, that is not itself
invalid, illegal or unenforceable) shall be construed so as to give effect to
the intent manifested thereby.

         16.  MODIFICATION AND WAIVER.  No supplement, modification, 
              ----------------------- 
termination or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of
this Agreement shall be deemed or shall constitute a waiver of any other
provisions hereof (whether or not similar) nor shall such waiver constitute a
continuing waiver.

Company in writing upon being served with any summons, citation, subpoena,
complaint, indictment, information or other document relating to any Proceeding

Non-Employee Directors.  Once appointed, such Committee shall continue to serve

time the Board may increase the size of the Committee and appoint additional
members thereof, remove members (with or without cause) and appoint new members
in substitution therefor, fill vacancies, however caused, and remove all members
of the Committee and thereafter directly administer the Plan, all to the extent

Committee designated by the Board, which Committee shall be constituted in such
a manner as to satisfy the legal requirements relating to the administration of
incentive stock option plans, if any, of California corporate and securities
laws, of the Code and of any applicable Stock Exchange (the "Applicable Laws").
Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board.  From time to time the Board may

remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused, and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws.

          (c) Powers of the Administrator.  Subject to the provisions of the
              ---------------------------                                   
Plan and in the case of a Committee, the specific duties delegated by the Board

accordance with Section 2(k) of the Plan;

               (ii) to select the Consultants and Employees to whom Options may

combination thereof are granted hereunder;

                                       4

               (v) to approve forms of agreement for use under the Plan;

               (vi) to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any Option granted hereunder;

               (vii)  in order to fulfill the purposes of the Plan and without
amending the Plan, to modify grants of Options to participants who are foreign
nationals or employed outside of the United States in order to recognize
differences in local law, tax policies or customs.

          (d) Effect of Administrator's Decision.  All decisions, determinations
              ----------------------------------                                
and interpretations of the Administrator shall be final and binding on all
holders of Options.

     5.  Eligibility.
         ----------- 

          (a) Recipients of Grants.  Nonstatutory Stock Options may be granted
              --------------------                                            
to Employees and Consultants.  Incentive Stock Options may be granted only to
Employees.  An Employee or Consultant who has been granted an Option may, if he
or she is otherwise eligible, be granted additional Options.

          (b) Type of Option.  Each Option shall be designated in the applicable
              --------------                                                    
Stock Option Agreement as either an Incentive Stock Option or a Nonstatutory
Stock Option.  However, notwithstanding such designations, to the extent that
the aggregate Fair Market Value of the Shares with respect to which Options
designated as Incentive Stock Options are exercisable for the first time by any
Optionee during any calendar year (under all plans of the Company or any Parent
or Subsidiary) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.  For purposes of this Section 5(b), Incentive Stock
Options shall be taken into account in the order in which they were granted, and
the Fair Market Value of the Shares subject to an Incentive Stock Option shall
be determined as of the date of the grant of such Option.

          (c) No Right to Employment.  The Plan shall not confer upon any
              ----------------------                                     
Optionee any right with respect to continuation of employment or consulting
relationship with the Company, nor shall it interfere in any way with such
Optionee's right or the Company's right to terminate his or her employment or
consulting relationship at any time, with or without cause.

     6.  Term of Plan.  The Plan shall become effective upon the earlier to
         ------------                                                      
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company as 

                                       5
<PAGE>
 
described in Section 16 of the Plan. It shall continue in effect for a term of
ten (10) years unless sooner terminated under Section 12 of the Plan.

     7.  Term of Option.  The term of each Option shall be the term stated in
         --------------                                                      
the applicable Stock Option Agreement; provided, however, that the term shall be
no more than ten (10) years from the date of grant thereof or such shorter term
as may be provided in any Stock Option Agreement.  However, in the case of an
Incentive Stock Option granted to an Optionee who, at the time the Option is
granted, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the term of
the Option shall be five (5) years from the date of grant thereof or such
shorter term as may be provided in the Option Agreement.

     8.  Option Exercise Price and Consideration.  The per share exercise price
         ---------------------------------------                               
for the Shares to be issued pursuant to exercise of an Option shall be such
price as is determined by the Board, but shall be subject to the following:

         (a) In the case of an Incentive Stock Option that is:

          (i) granted to an Employee who, at the time of the grant of such
Incentive Stock Option, owns stock representing more than ten percent (10%) of
the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 100% of the Fair
Market Value per Share on the date of grant.

          (ii) granted to any other Employee, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

         (b) In the case of a Nonstatutory Stock Option that is:

          (i) granted to a person who, at the time of the grant of such Option,
owns stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the per Share
exercise price shall be no less than 110% of the Fair Market Value per Share on
the date of the grant.

          (ii) granted to any other person, the per Share exercise price shall
be no less than 85% of the Fair Market Value per Share on the date of grant.

     9.  Exercise of Option.
         ------------------ 

         (a) Procedure for Exercise; Rights as a Shareholder.  Any Option
             -----------------------------------------------             
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan; provided that such Option shall become 

                                       6
<PAGE>
 
exercisable at the rate of at least twenty percent (20%) per year over five (5)
years from the date the Option is granted.

          An Option may not be exercised for a fraction of a Share.  Exercise of
an Option in any manner shall result in a decrease in the number of Shares that
thereafter may be available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

           (b) Rule 16b-3.  Options granted to Reporting Persons shall comply
               ----------                                                    
with Rule 16b-3 and shall contain such additional conditions or restrictions as
may be required thereunder to qualify for the maximum exemption for Plan
transactions.

     10.  Stock Withholding to Satisfy Withholding Tax Obligations.  At the
          --------------------------------------------------------         
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph.  When an Optionee incurs tax liability in
connection with an Option, which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by one or some combination of the
following methods: (a) by cash payment, (b) out of Optionee's current
compensation, (c) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or less than Optionee's marginal tax rate times the
ordinary income recognized, or (d) by electing to have the Company withhold from
the Shares to be issued upon exercise of the Option, if any, that number of
Shares having a fair market value equal to the amount required to be withheld.
For this purpose, the fair market value of the Shares to be withheld shall be
determined on the date that the amount of tax to be withheld is to be determined
(the "Tax Date").

          Any surrender by a Reporting Person of previously owned Shares to
satisfy tax withholding obligations arising upon exercise of an Option must
comply with the applicable provisions of Rule 16b-3 and shall be subject to such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

          All elections by an Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (a) the election must be made on or prior to the applicable Tax Date;

          (b) once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made;

                                       7
<PAGE>
 
          (c) all elections shall be subject to the consent or disapproval of
the Administrator;

          (d) if the Optionee is a Reporting Person, the election must comply
with the applicable provisions of Rule 16b-3 and shall be subject to such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

          In the event the election to have Shares withheld is made by an
Optionee and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

     11.  Time of Granting Options.  The date of grant of an Option shall, for
          ------------------------                                            
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Board.  Notice
of the determination shall be given to each Employee or Consultant to whom an
Option is so granted within a reasonable time after the date of such grant.

     12.  Amendment and Termination of the Plan.
          ------------------------------------- 

          (a) Authority to Amend and Terminate.  The Board may at any time
              --------------------------------                            
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made that would impair the rights of any
Optionee under any grant theretofore made, without his or her consent.  In
addition, to the extent necessary and desirable to comply with Rule 16b-3 or
with Section 422 of the Code (or any other applicable law or regulation,
including the requirements of any Stock Exchange), the Company shall obtain
shareholder approval of any Plan amendment in such a manner and to such a degree
as required.

          (b) Effect of Amendment or Termination.  No amendment or termination
              ----------------------------------                              
of the Plan shall adversely affect Options already granted, unless mutually
agreed otherwise between the Optionee and the Board, which agreement must be in
writing and signed by the Optionee and the Company.

     13.  Conditions Upon Issuance of Shares.  Shares shall not be issued
          ----------------------------------                             
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, rule and regulation, including, without limitation,
the Securities Act of 1933, as amended, the Exchange Act, the rules and
regulations promulgated thereunder, the requirements of any Stock Exchange, and
the requirements of any governmental agencies.

                                       8
<PAGE>
 
          Each Option is subject to the requirement that, if at any time the
Board determines, in its absolute discretion, that the listing, registration or
qualification of Common Stock issuable pursuant to the Plan is required by any
securities exchange or under any state or federal law, or the consent or
approval of any governmental regulatory body is necessary or desirable as a
condition to, or in connection with, the issuance of Common Stock, no such
payment made or Common Stock issued, in whole or in part, unless listing,
registration, qualification, consent or approval has been effected or obtained
free of any conditions not acceptable to the Board.

     14.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------                                             
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary for the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have bene obtained.

     15.  Agreements.  Any Nonstatutory Stock Option granted shall be evidenced
          ----------                                                           
by a stock option agreement substantially similar to the Stock Option Agreement,
as may be amended from time to time by the Board, the terms of which are
incorporated in and deemed to be a part of the Plan.  Any Incentive Stock Option
granted shall be evidenced by a stock option agreement substantially similar to
the Stock Option Agreement, as modified to include such terms and conditions
which the Board deems necessary to comply with the provisions of Code Section
422.

     16.  Shareholder Approval.  Continuance of the Plan shall be subject to
          --------------------                                              
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted.  Such shareholder approval shall be obtained
in the degree and manner required under applicable state and federal law and the
rules of any Stock Exchange.  All Options issued under the Plan shall become
void in the event such approval is not obtained.

     17.  Information to Optionees.  The Company shall provide financial
          ------------------------                                      
statements at least annually to each Optionee during the period such Optionee
has one or more Options outstanding, and in the case of an individual who
acquired Shares pursuant to the Plan, during the period such individual owns
such Shares.

     NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and conditions hereinafter set forth and other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties hereto agree as follows:

     1.  GeoCities hereby grants to the Optionee the option to purchase ______
shares of Common Stock at a price per share of $________ upon the terms and
subject to the conditions set forth herein.

     2.  Subject to the conditions set forth herein, the right to exercise this
option shall accrue in periodic installments as follows:

          (i) commencing with the period of twelve (12) consecutive months
     beginning one (1) year after the date of this Agreement, this option may be
     exercised to the extent of ___________ shares;

          (ii) commencing with the period of twelve (12) consecutive months
     beginning two (2) years after the date of this Agreement, this option may
     be exercised to the extent of an additional ____________ shares;

          (iii)  commencing with the period of twelve (12) consecutive months
     beginning three (3) years after the date of this Agreement, this option may
     be exercised to the extent of an additional _____________ shares; and

          (iv) commencing with the period of twelve (12) consecutive months
     beginning four (4) years after the date of this Agreement, this option may
     be exercised to the extent of an additional ____________ shares.
<PAGE>
 
This option may be exercised, in whole or in part, subject to the limitations
imposed by the exercise schedule set forth above, at any time and from time to
time commencing with the respective dates on which each portion becomes
exercisable and continuing until the seventh (7th) anniversary of the date of
this Agreement, at which time the entire unexercised portion of this option
shall expire.

     3.  In the event of termination of the Optionee's employment for cause, as
defined below, this option shall immediately terminate.  If the Optionee's
employment is terminated for any reason other than for cause, then this option
may be exercised, to the extent this option was exercisable on the date of such
cessation of employment, within [three (3) months/thirty (30) days] after the
date he ceases to be an employee of GeoCities.  An approved leave of absence
shall not be deemed a termination of employment for purposes of this Agreement,
but no option may be exercised during any such leave of absence, except during
the first three (3) months thereof.  Solely for purposes of this paragraph 3,
"cause" shall mean any fair and honest cause or reason assigned in good faith by
the Board of Directors or any officer of GeoCities.

     4.  This option shall be exercisable by the Optionee only during his
lifetime.  This option shall be nontransferable by the Optionee, other than by
will or the laws of descent and distribution.

     5.  In the event of the Optionee's death or permanent and total disability
while in the employ of GeoCities, or during the period following termination of
employment during which the Optionee is permitted to exercise an option pursuant
to Paragraph 3 hereof, this option may be exercised, to the extent that it was
otherwise executable as of the date of such death, disability or termination of
employment, by the Optionee or his transferee within one (1) year after the date
the Optionee dies or becomes permanently and totally disabled.  The Optionee's
transferee shall be the person or persons entitled to exercise the option under
the Optionee's will, or, if no testamentary disposition of the option shall have
been made, his legal representative.  Any transferee exercising the option must
furnish GeoCities with:  (a) written confirmation of his status as transferee;
(b) evidence satisfactory to GeoCities to establish the validity of the transfer
of this option in compliance with this Agreement and with any laws or
regulations pertaining to said transfer; and (c) written acceptance of the terms
and conditions of this option as prescribed in this Agreement.

     6.  Subject to any required action of GeoCities's stockholders, the
existence of outstanding options hereunder shall not affect GeoCities's right or
power to make or authorize any or all adjustments, recapitalizations,
reorganizations or other changes in its capital structure or business; to
approve any merger or consolidation, issuance of bonds, debentures, preferred or
prior preference stock ahead of or affecting the Common Stock; to elect its
dissolution or liquidation or that of any of its subsidiaries; to sell or
transfer any of its business; or to do any other corporate act whether similar
to the events described above or otherwise.  If the number of outstanding shares
of Common Stock is increased or decreased or changed into or exchanged for a
different number or kind of securities, whether of GeoCities or any other
corporation, by reason of recapitalization, reclassification, stock split,
combination of shares, stock dividends or other similar event, the number and
kind of securities as to which outstanding options may be exercised, and the
option price at which outstanding options may be exercised may be adjusted by
the Board of Directors, whose determination shall be binding and final.

                                      -2-

     7.  This option may be exercised in accordance with the terms hereof by:
(a) giving written notice of such exercise to GeoCities, specifying the number
of whole shares to be purchased and accompanied by full payment of the purchase
price thereof, either in cash, by check, or by delivery to GeoCities of shares
of Common Stock already owned by the Optionee (duly endorsed in favor of
GeoCities or accompanied by a duly endorsed stock power) together with the
amount of any income tax GeoCities is required by law to withhold by reason of
such exercise, and (b) giving satisfactory assurances in writing, if requested
by GeoCities, signed by the person exercising this option, that the shares to be
purchased upon such exercise are being purchased for investment and not with the
view to distribution thereof.

     8.  (a)  Notwithstanding anything contained herein to the contrary, in the
event that the Optionee ceases to be employed by GeoCities for any reason
(including, without limitation, as a result of resignation, retirement,
dismissal with or without cause, death or disability), GeoCities shall have the
first right and option, and the holders of Senior Securities (as defined below)
shall have the second right and option, to purchase from the Optionee (or, in
the case of death, from the Optionee's legal representative) all shares of
Common Stock held by the Optionee on the date of cessation of employment or
purchased by the Optionee following such date as permitted under Sections 3 and
5 hereof.  In the event that GeoCities or any holder of Senior Securities shall
exercise such right and option, then the exercising party shall pay the
Optionee, as the purchase price for such shares of Common Stock, the Fair Market
Value (as defined below) of such shares.  GeoCities may exercise its first right
and option by delivering notice to Optionee and to each holder of Senior
Securities within ninety (90) days following the cessation of the Optionee's
employment or the subsequent purchase of shares, as applicable, of its intent to
exercise its repurchase right and the Fair Market Value, and shall have paid for
such shares in cash at the end of such 90th day (unless the Fair Market Value of
the shares has not been conclusively determined as of such date, in which case
GeoCities may, at its sole option, pay the Optionee the estimated Fair Market
Value at the end of such 90th day, subject to adjustment upon the final
determination of the Fair Market Value, or pay the Optionee promptly after the
Fair Market Value is determined in accordance with subparagraph (d) below).

          (b) If GeoCities fails to fully exercise its right to repurchase all
of the Optionee's shares of Common Stock after the cessation of the Optionee's
employment or the subsequent purchase of shares, as applicable, then GeoCities
shall give the Optionee and each holder of its Series A Preferred Stock, Series
B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock (other
than those shares of Series D Preferred Stock held by Venture Lending or its
approved transferees), or Common Stock issued upon conversion thereof
(collectively, the "Senior Securities"), notice ("Termination Notice") of such
fact, the number of shares of Common Stock available for purchase by each such
holder and GeoCities' determination of the Fair Market Value of such shares. The
holders of the Senior Securities shall have the right to purchase the Optionee's
Common Stock, on a pro-rata basis, by giving GeoCities notice of their intent to
exercise such option ("Notice of Election") within twenty (20) days after the
receipt of the Termination Notice from GeoCities, together with cash in the
amount of the purchase price (unless the Fair Market Value of the shares has not
been conclusively determined as of such date, in which case each such holder
shall pay the Optionee promptly after the Fair Market Value has been
conclusively determined in accordance with subparagraph (d) below).  For
purposes of this subparagraph (b), "pro rata basis" shall be equal to the
product obtained by multiplying (i) the number of the Optionee's shares not
purchased by GeoCities by (ii) a fraction, the numerator of which is the number
of shares of Senior Securities held by such 

                                      -3-
<PAGE>
 
holder (on an as-converted basis) and the denominator of which is the total
number of shares held by all the holders of Senior Securities (on an as-
converted basis).

          (c) Any holder of Senior Securities that fails to provide a timely
Notice of Election shall be deemed to have elected to not purchase any shares in
a transaction pursuant to this Paragraph 8.  If any holder of Senior Securities
elects (or is deemed to have elected) not to fully participate in a transaction
pursuant to this Paragraph 8, then GeoCities shall so notify the other holders
of Senior Securities who elected to participate (the "Repurchase Holders").
Such notice may be made by telephone if confirmed in writing within two (2)
days.  The Repurchase Holders shall have five (5) days from the date such notice
was given to agree to purchase their pro rata share of the unsold portion of the
Optionee's shares.  For purposes of this subparagraph (iv), a "pro rata share"
shall be equal to the product obtained by multiplying (i) the number of the
Optionee's shares in the unsold portion by (ii) a fraction, the numerator of
which is the number of shares of Senior Securities held by such Repurchase
Holder (on an as-converted basis) and the denominator of which is the total
number of shares held by all of the Repurchase Holders (on an as-converted
basis).

          (d) If the Optionee objects to the Fair Market Value as so proposed,
then the Optionee may request an appraisal by written notice of objection
delivered not later than ten (10) days after receipt of the Fair Market Value
set by GeoCities' Board of Directors.  If an appraisal is requested, the
Optionee and GeoCities shall jointly select an appraiser to determine the Fair
Market Value of the Optionee's shares.  If the Optionee and GeoCities cannot
agree on an appraiser, each shall select its own appraiser (each, a "Party
Appraiser") and the two Party Appraisers shall jointly select a third appraiser
(the "Arbitrating Appraiser").  Each of the Party Appraisers shall submit its
appraisal to the Arbitrating Appraiser, and the Arbitrating Appraiser shall
select one of such appraisals as the Fair Market Value.  All expenses of such
appraisal shall be paid by the Optionee, unless the Fair Market Value as
determined by such appraisal is at least five percent (5%) greater than the Fair
Market Value initially set by the Board of Directors, in which case GeoCities
and the holders of the Senior Securities shall pay for the appraisal in
proportion to each party's purchase of the Optionee's shares.

     9.  The Optionee may not sell or engage in any transaction which has
resulted in or will result in a change in the beneficial or record ownership of
any shares of Common Stock held by the Optionee, including without limitation a
voluntary or involuntary sale, assignment, transfer, pledge, hypothecation,
encumbrance, disposal, loan, gift, attachment or levy (a "Transfer"), except as
provided in this Agreement, and any such Transfer of shares of Common Stock or
attempted Transfer of shares of Common Stock in contravention of this Agreement
shall be void and ineffective for any purpose or confer on any transferee or
purported transferee any rights whatsoever.

     10.  (a)  Each time the Optionee proposes to Transfer (or is required by
operation of law or other involuntary transfer) any or all of the shares of
Common Stock standing in the Optionee's name or owned by him or her during the
term of this Agreement, the Optionee shall first offer such shares to GeoCities
and the holders of the Senior Securities in accordance with the following
provisions:

          (i) The Optionee shall deliver a written notice (a "Notice") to
     GeoCities stating (A) the Optionee's bona fide intention to Transfer such
     shares, (B) the name 

                                      -4-
<PAGE>
 
     and the address of the proposed transferee, (C) the number of shares to be
     transferred, and (D) the purchase price per share and terms of payment for
     which the Optionee proposes to Transfer such shares.

          (ii) Within thirty (30) days after receipt of the Notice, GeoCities
     shall have the first right to purchase or obtain such shares, upon the
     price and terms of payment designated in the Notice.  If the Notice
     provides for the payment of non-cash consideration, GeoCities at its option
     may pay the consideration in cash equal to GeoCities' good faith estimate
     of the present fair market value of the non-cash consideration offered.

          (iii)  If GeoCities elects not to purchase or obtain all of the shares
     designated in the Optionee's Notice, then GeoCities shall promptly provide
     written notice of such fact, together with a copy of the Notice, to the
     holders of the Senior Securities.  The holders of the Senior Securities
     shall have an additional thirty (30) days immediately following the receipt
     of the Notice from GeoCities in which to purchase the shares not purchased
     by GeoCities on a prorata basis upon the terms and conditions specified in
     subparagraph (ii) above by giving GeoCities notice of their intent to
     exercise such option ("Notice of Purchase") within thirty (30) days after
     the receipt of the Termination Notice from GeoCities.  For purposes of this
     subparagraph (iii), "pro rata" shall be equal to the product obtained by
     multiplying (i) the number of the Optionee's shares not purchased by
     GeoCities by (ii) a fraction, the numerator of which is the number of
     shares of Senior Securities held by such holder (on an as-converted basis)
     and the denominator of which is the total number of shares held by all the
     holders of Senior Securities (on an as-converted basis).

          (iv) Any holder of Senior Securities that fails to provide a timely
     Notice of Purchase shall be deemed to have elected to not purchase any
     shares in a transaction pursuant to this Paragraph 10.   If any holder of
     Senior Securities elects (or is deemed to have elected) not to fully
     participate in a transaction pursuant to this Paragraph 10, then GeoCities
     shall so notify the other holders of Senior Securities who elected to
     participate (the "Right of First Refusal Holders").  Such notice may be
     made by telephone if confirmed in writing within two (2) days. The Right of
     First Refusal Holders shall have five (5) days from the date such notice
     was given to agree to purchase their pro rata share of the unsold portion
     of the Optionee's shares.  For purposes of this subparagraph (iv), a "pro
     rata share" shall be equal to the product obtained by multiplying (i) the
     number of the Optionee's shares in the unsold portion by (ii) a fraction,
     the numerator of which is the number of shares of Senior Securities held by
     such Right of First Refusal Holder (on an as-converted basis) and the
     denominator of which is the total number of shares of Senior Securities
     held by all the Right of First Refusal Holders (on an as-converted basis).

          (v) If neither (x) GeoCities nor (y) any of the holders of the Senior
     Securities elects to purchase or obtain all of the shares designated in the
     Optionee's Notice, then the Optionee may Transfer the unsold shares
     referred to in the Notice to the proposed transferee, providing such
     Transfer (A) is completed within 180 days 

                                      -5-
<PAGE>
 
     after the expiration of the right of GeoCities and the holders of the
     Senior Securities to purchase or obtain such shares, (B) is made at the
     same price and terms designated in the Notice, and (C) the proposed
     transferee agrees to be bound by the terms and provisions of a buy-sell
     agreement substantially similar to the terms of Paragraphs 9 through 13 of
     this Agreement and to become a party to such an agreement immediately upon
     receipt of such shares. If such shares are not so transferred, the Optionee
     must give notice in accordance with this paragraph prior to any other or
     subsequent Transfer of such shares.

     (b) Notwithstanding Paragraph 9(a), the Optionee may Transfer for no or
nominal consideration shares to (i) the Optionee's spouse, parents,
grandparents, siblings, children or grandchildren or other members of the
Optionee's family (including relatives by marriage), or to a custodian, trustee
or other fiduciary for the account of the Optionee or members of his or her
family, or to any one other person designated by the Optionee, or (ii) by way of
bequest or inheritance upon death; provided that the Optionee or his
representative notifies GeoCities of such Transfer not less than ten (10) nor
more than ninety (90) days prior to the Transfer and that the proposed
transferee agrees to be bound by the terms and provisions of a buy-sell
agreement substantially similar to the terms of Paragraphs 8 through 13 of this
Agreement and to become a party to such an agreement immediately upon the
receipt of such shares.  Such buy-sell agreement shall provide that, for
purposes of the paragraph in such buy-sell agreement that is analogous to
Paragraph 8 of this Agreement, a cessation of the Optionee's employment with
GeoCities shall be deemed to be a cessation of employment by the transferee.

     11.  Notwithstanding any provisions to the contrary contained in this
Agreement, GeoCities' obligations to pay or complete payment for any shares to
be purchased by it under this Agreement are subject to its being legally
permitted to do so under the tests contained in Sections 500 and 501 of the
California General Corporation Law or any successor statute applicable thereto.
The inability of GeoCities to validly purchase any shares hereunder by reason of
its failure to meet the tests contained in Sections 500 and 501 of the
California General Corporation Law shall not be deemed to affect or limit in any
way the ability of the holders of the Senior Securities to purchase the shares.

     12.  Each certificate representing shares owned of record or beneficially
by a party to this Agreement shall be endorsed with the following legend:

          THE SHARES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO A STOCK OPTION
     AGREEMENT BETWEEN GEOCITIES AND THE HOLDER OF THE SHARES EVIDENCED BY THIS
     CERTIFICATE, PROVIDING FOR, AMONG OTHER MATTERS, THE RIGHT OF GEOCITIES AND
     CERTAIN SHAREHOLDERS THEREOF TO REPURCHASE THE SHARES AND THE RIGHT OF
     FIRST REFUSAL TO PURCHASE THE SHARES REPRESENTED BY THIS CERTIFICATE.  A
     COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL BUSINESS OFFICE OF
     GEOCITIES.

Under no circumstances shall any Transfer of any shares subject hereto be valid
until the proposed transferee thereof shall have agreed to be bound by the terms
and provisions of a buy-sell agreement 

                                      -6-
<PAGE>
 
substantially similar to the terms of Paragraphs 9 through 13 of this Agreement
and to become a party to such an agreement immediately upon receipt of such
shares; and notwithstanding any other provisions of this Agreement, no such
Transfer of any kind shall in any event result in the non-applicability of the
provisions hereof at any time to any of the shares subject hereto.

     13.  The restrictions on Transfer of shares set forth in this Agreement
shall terminate upon the consummation of a firm commitment underwritten public
offering from which GeoCities receives gross proceeds of not less than $20
million and in which the offering price per share (prior to underwriting
commissions and expenses) equals at least $10 (as adjusted for stock splits,
stock dividends, reorganizations and the like).

     14.  This Agreement is made solely for the benefit of the parties to this
Agreement and their respective successors and assigns, and, except as provided
in Paragraphs 8 through 13, no other person or entity shall have or acquire any
right by virtue of this Agreement.  Each holder of the Senior Securities shall
be a third-party beneficiary of Paragraphs 8 through 13 of this Agreement.

     15.  Unless the shares to be issued are at the time of issuance registered
under the Securities Act of 1933, as amended, this option is granted on the
condition that the purchase of stock hereunder shall be for investment purposes
and not with the view to resale or distribution.

     16.  Neither the Optionee nor any person claiming under or through him
shall be, or have any of the rights or privileges of, a stockholder of GeoCities
with respect to any of the shares issuable upon the exercise of this option,
unless and until certificates representing such shares shall have been issued
and delivered to him.

     17.  Any notice to be given to GeoCities under the terms of this Agreement
shall be addressed to GeoCities, in care of its President, at 1918 Main Street,
Third Floor, Santa Monica, California 90405-1030, or to such other address as
GeoCities may hereafter designate in writing.  Any notice to be given to the
Optionee shall be addressed to the Optionee at the address set forth beneath his
signature hereto, or at any other address as the Optionee may hereafter
designate in writing.  Any such notice shall be deemed to have been duly given
if and when personally delivered, or if mailed, two (2) business days following
its being deposited in the United States mails in a properly sealed envelope,
addressed as aforesaid, registered or certified, postage prepaid.

     18.  Except as otherwise provided herein, this option and the rights and
privileges conferred by this Agreement may not be transferred, assigned, pledged
or hypothecated by the Optionee in any way (whether by operation of law or
otherwise) and shall not be subject to sale under execution, attachment or
similar process.  Upon any attempt to transfer, assign, pledge, hypothecate or
otherwise dispose of this option, or of any right or privilege conferred hereby,
contrary to the provisions hereof, or upon any attempted sale under any
execution, attachment or similar process upon the rights and privileges
conferred hereby, this option and the rights and privileges conferred upon the
Optionee in this Agreement shall immediately become null and void.

     19.  Subject to the limitations on transferability contained herein, this
Agreement shall be binding upon and inure to the benefit of the heirs, legal
representatives, successors and assigns of the parties hereto.

                                      -7-

     20.  Nothing in this Agreement is intended, nor shall it be deemed, to
create any employment agreement between the Optionee and GeoCities or to impose
any obligation on the part of GeoCities to maintain Optionee's employment with
GeoCities, and any rights that the Optionee may have GeoCities with respect to
the Optionee's employment, other than as an at-will employee, shall be as set
forth in a written employment agreement between the Optionee and GeoCities, if
any.

     21.  The option granted to the Optionee under this Agreement is subject to
the adoption by the Board of Directors and shareholders of GeoCities of
GeoCities' 1997 Stock Option Plan, a copy of which is enclosed herewith.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement, in
duplicate, as of the day and year first above written.

                              GENERAL PROVISIONS
                              ------------------


    I.    PURPOSE OF THE PLAN

          This 1998 Stock Incentive Plan is intended to promote the interests of
GeoCities, a California corporation, by providing eligible persons with the
opportunity to acquire a proprietary interest, or otherwise increase their
proprietary interest, in the Corporation as an incentive for them to remain in
the service of the Corporation.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

    II.   STRUCTURE OF THE PLAN

          A. The Plan shall be divided into five separate equity programs:

          (i)   the Discretionary Option Grant Program under which eligible
persons may, at the discretion of the Plan Administrator, be granted options to
purchase shares of Common Stock,

          (ii)  the Salary Investment Option Grant Program under which eligible
employees may elect to have a portion of their base salary invested each year in
special options,

          (iii) the Stock Issuance Program under which eligible
persons may, at the discretion of the Plan Administrator, be issued shares of
Common Stock directly, either through the immediate purchase of such shares or
as a bonus for services rendered the Corporation (or any Parent or Subsidiary),

          (iv)  the Automatic Option Grant Program under which eligible non-
employee Board members shall automatically receive options at periodic intervals
to purchase shares of Common Stock, and

          (v)   the Director Fee Option Grant Program under which non-employee
Board members may elect to have all or any portion of their annual retainer fee
otherwise payable in cash applied to special options.
<PAGE>
 
          B.  The provisions of Articles One and Seven shall apply to all equity
programs under the Plan and shall govern the interests of all persons under the
Plan.

     III. ADMINISTRATION OF THE PLAN

          A.   Prior to the Section 12 Registration Date, the Discretionary
Option Grant and Stock Issuance Programs shall be administered by the Board.
Beginning with the Section 12 Registration Date, the following provisions shall
govern the administration of the Plan:

               (i)   The Board shall have the authority to administer the
Discretionary Option Grant and Stock Issuance Programs with respect to Section
16 Insiders but may delegate such authority in whole or in part to the Primary
Committee.

               (ii)  Administration of the Discretionary Option Grant and Stock
Issuance Programs with respect to all other persons eligible to participate in
those programs may, at the Board's discretion, be vested in the Primary
Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons.

               (iii) The Primary Committee shall have the sole and exclusive
authority to determine which Section 16 Insiders and other highly compensated
Employees shall be eligible for participation in the Salary Investment Option
Grant Program for one or more calendar years. However, all option grants under
the Salary Investment Option Grant Program shall be made in accordance with the
express terms of that program, and the Primary Committee shall not exercise any
discretionary functions with respect to the option grants made under that
program.

               (iv)   Administration of the Automatic Option Grant and Director
Fee Option Grant Programs shall be self-executing in accordance with the terms
of those programs.

          B.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full power and authority
subject to the provisions of the Plan:

               (i)   to establish such rules as it may deem appropriate for
proper administration of the Plan, to make all factual determinations, to
construe and interpret the provisions of the Plan and the awards thereunder and
to resolve any and all ambiguities thereunder;

               (ii)  to determine, with respect to awards made under the
Discretionary Option Grant and Stock Issuance Programs, which eligible persons
are to receive such awards, the time or times when such awards are to be made,
the number of shares to be covered by each such award, the vesting schedule (if
any) applicable to the award, the status of a granted option as either an
Incentive Option or a Non-Statutory Option and the maximum term for which the
option is to remain outstanding;

                                       2.
<PAGE>
 
               (iii) to amend, modify or cancel any outstanding award with the
consent of the holder or accelerate the vesting of such award; and

               (iv)  to take such other discretionary actions as permitted
pursuant to the terms of the applicable program.

Decisions of each Plan Administrator within the scope of its administrative
functions under the Plan shall be final and binding on all parties.

          C.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time.  The Board may also at any time terminate the functions
of any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

          D.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee.  No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any options or stock issuances under the Plan.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                    (i)   Employees,

                    (ii)  non-employee members of the Board or the board of 
     directors of any Parent or Subsidiary, and

                    (iii) consultants and other independent advisors who provide
     services to the Corporation (or any Parent or Subsidiary).

          B.   Only Employees who are Section 16 Insiders or other highly
compensated individuals shall be eligible to participate in the Salary
Investment Option Grant Program.

          C.   Only non-employee Board members shall be eligible to participate
in the Automatic Option Grant and Director Fee Option Grant Programs.

     V.   STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open

                                       3.
<PAGE>
 
market.  The maximum number of shares of Common Stock initially reserved for
issuance over the term of the Plan shall not exceed 2,670,940 shares.
Such authorized share reserve consists of (i) the number of shares which remain
available for issuance, as of the Plan Effective Date, under the Predecessor
Plan as last approved by the Corporation's stockholders, including the shares
subject to the outstanding options to be incorporated into the Plan and the
additional shares which would otherwise be available for future grant, plus (ii)
an increase authorized by the Board but subject to stockholder approval prior to
the Section 12 Registration Date.

          B.   No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 500,000 shares of Common Stock in the aggregate per calendar year,
beginning with the 1998 calendar year.

          C.   Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent those options
expire, terminate or are cancelled for any reason prior to exercise in full.
Unvested shares issued under the Plan and subsequently repurchased by the
Corporation, at the original exercise or issue price paid per share, pursuant to
the Corporation's repurchase rights under the Plan shall be added back to the
number of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent options
or direct stock issuances under the Plan.  However, should the exercise price of
an option under the Plan be paid with shares of Common Stock or should shares of
Common Stock otherwise issuable under the Plan be withheld by the Corporation in
satisfaction of the withholding taxes incurred in connection with the exercise
of an option or the vesting of a stock issuance under the Plan, then the number
of shares of Common Stock available for issuance under the Plan shall be reduced
by the gross number of shares for which the option is exercised or which vest
under the stock issuance, and not by the net number of shares of Common Stock
issued to the holder of such option or stock issuance.  Shares of Common Stock
underlying one or more stock appreciation rights exercised under the Plan shall
NOT be available for subsequent issuance.

          D.   If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities by which the share reserve is
to increase each calendar year pursuant to the automatic share increase
provisions of the Plan, (iii) the number and/or class of securities for which
any one person may be granted options, separately exercisable stock appreciation
rights and direct stock issuances under the Plan per calendar year, (iv) the
number and/or class of securities for which grants are subsequently to be made
under the Automatic Option Grant Program to new and continuing non-employee
Board members, (iv) the number and/or class of securities and the exercise price
per share in effect under each outstanding option under the Plan and (v) the
number and/or class of securities and price per share in effect under each
outstanding option incorporated into this Plan from the Predecessor Plan.  Such
adjustments to the outstanding options are to be effected in a manner

                                       4.
<PAGE>
 
which shall preclude the enlargement or dilution of rights and benefits under
such options. The adjustments determined by the Plan Administrator shall be
final, binding and conclusive.

                                       5.

                       DISCRETIONARY OPTION GRANT PROGRAM
                       ----------------------------------

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
                                    --------                                  
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   EXERCISE PRICE.
               -------------- 

               1.      The exercise price per share shall be fixed by the Plan
Administrator at the time of the option grant.

               2.      The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section II of
Article Seven and the documents evidencing the option, be payable in cash or
check made payable to the Corporation.  Should the Common Stock be registered
under Section 12 of the 1934 Act at the time the option is exercised, then the
exercise price may also be paid as follows:

                  (i)     shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

                  (ii)    to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable instructions to (a) a
     Corporation-approved brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by reason of such exercise and (b) the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

                                       6.
<PAGE>
 
          B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be exercisable
               ----------------------------                                   
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option.  However, no option shall have a term in excess of ten
(10) years measured from the option grant date.

          C.   CESSATION OF SERVICE.
               -------------------- 

          1.     The following provisions shall govern the exercise of any
options outstanding at the time of the Optionee's cessation of Service or death:

               (i)     Any option outstanding at the time of the Optionee's
     cessation of Service for any reason shall remain exercisable for such
     period of time thereafter as shall be determined by the Plan Administrator
     and set forth in the documents evidencing the option, but no such option
     shall be exercisable after the expiration of the option term.

               (ii)    Any option exercisable in whole or in part by the
     Optionee at the time of death may be subsequently exercised by his or her
     Beneficiary.

               (iii)   During the applicable post-Service exercise period, the
     option may not be exercised in the aggregate for more than the number of
     vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service.  Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised.  However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding to the extent the option is not otherwise at that time
     exercisable for vested shares.

               (iv)    Should the Optionee's Service be terminated for
     Misconduct or should the Optionee engage in Misconduct while his or her
     options are outstanding, then all such options shall terminate immediately
     and cease to be outstanding.

          2.     The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding:

               (i)     to extend the period of time for which the option is to
     remain exercisable following the Optionee's cessation of Service to such
     period of time as the Plan Administrator shall deem appropriate, but in no
     event beyond the expiration of the option term, and/or

                                       7.
<PAGE>
 
               (ii)    to permit the option to be exercised, during the
     applicable post-Service exercise period, for one or more additional
     installments in which the Optionee would have vested had the Optionee
     continued in Service.

          D.   STOCKHOLDER RIGHTS.  The holder of an option shall have no
               ------------------                                        
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   REPURCHASE RIGHTS.  The Plan Administrator shall have the
               -----------------                                        
discretion to grant options which are exercisable for unvested shares of Common
Stock.  Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, any or all of those unvested shares.  The terms upon which such
repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right.

          F.   LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of the
               ----------------------------------                             
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death.  Non-Statutory Options shall be
subject to the same restrictions, except that a Non-statutory Option may, to the
extent permitted by the Plan Administrator, be assigned in whole or in part
during the Optionee's lifetime to one or more members of the Optionee's
immediate family or to a trust established exclusively for one or more such
family members.  The terms applicable to the assigned portion shall be the same
as those in effect for the option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Seven shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall not be subject to the terms of this Section II.
                                 ---                                            

          A.   ELIGIBILITY.  Incentive Options may only be granted to Employees.
               -----------                                                      

          B.   EXERCISE PRICE.  The exercise price per share shall not be less
               --------------                                                 
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

          C.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the shares
               -----------------                                                
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during

                                       8.
<PAGE>
 
any one calendar year shall not exceed the sum of One Hundred Thousand Dollars
($100,000).  To the extent the Employee holds two (2) or more such options which
become exercisable for the first time in the same calendar year, the foregoing
limitation on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.

          D.   10% STOCKHOLDER.  If any Employee to whom an Incentive Option is
               ---------------                                                 
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

     III. CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   Each option outstanding at the time of a Change in Control but
not otherwise fully-vested shall automatically accelerate so that each such
option shall, immediately prior to the effective date of the Change in Control,
become exercisable for all of the shares of Common Stock at the time subject to
that option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock.  However, an outstanding option shall not so accelerate
if and to the extent:  (i) such option is, in connection with the Change in
Control, assumed or otherwise continued in full force and effect by the
successor corporation (or parent thereof) pursuant to the terms of the Change in
Control, (ii) such option is replaced with a cash incentive program of the
successor corporation which preserves the spread existing at the time of the
Change in Control on the shares of Common Stock for which the option is not
otherwise at that time exercisable and provides for subsequent payout in
accordance with the same vesting schedule applicable to those option shares or
(iii) the acceleration of such option is subject to other limitations imposed by
the Plan Administrator at the time of the option grant.

          B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Change in Control, except to
the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) or otherwise continue in full force and effect
pursuant to the terms of the Change in Control or (ii) such accelerated vesting
is precluded by other limitations imposed by the Plan Administrator at the time
the repurchase right is issued.

          C.   Immediately following the consummation of the Change in Control,
all outstanding options shall terminate and cease to be outstanding, except to
the extent assumed by the successor corporation (or parent thereof) or otherwise
expressly continued in full force and effect pursuant to the terms of the Change
in Control.

          D.   Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted, immediately after such Change in
Control, to apply to the number and class of securities which would have been
issuable to the Optionee in consummation of such Change in Control had the
option been exercised immediately prior to such Change in Control.  Appropriate
adjustments to reflect such Change in Control shall also be made to (i) the
exercise

                                       9.
<PAGE>
 
price payable per share under each outstanding option, provided the aggregate
                                                       --------              
exercise price payable for such securities shall remain the same, (ii) the
maximum number and/or class of securities available for issuance over the
remaining term of the Plan and (iii) the maximum number and/or class of
securities for which any one person may be granted options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year.

          E.   The Plan Administrator may at any time provide that one or more
options will automatically accelerate in connection with a Change in Control,
whether or not those options are assumed or otherwise continued in full force
and effect pursuant to the terms of the Change in Control.  Any such option
shall accordingly become exercisable, immediately prior to the effective date of
such Change in Control, for all of the shares of Common Stock at the time
subject to that option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock.  In addition, the Plan Administrator may at
any time provide that one or more of the Corporation's repurchase rights shall
not be assignable in connection with such Change in Control and shall terminate
upon the consummation of such Change in Control.

          F.   The Plan Administrator may at any time provide that one or more
options will automatically accelerate upon an Involuntary Termination of the
Optionee's Service within a designated period (not to exceed eighteen (18)
months) following the effective date of any Change in Control in which those
options do not otherwise accelerate.  Any options so accelerated shall remain
exercisable for fully-vested shares until the earlier of (i) the expiration of
                                              -------                         
the option term or (ii) the expiration of the one (1) year period measured from
the effective date of the Involuntary Termination.  In addition, the Plan
Administrator may at any time provide that one or more of the Corporation's
repurchase rights shall immediately terminate upon such Involuntary Termination.

          G.   The Plan Administrator may at any time provide that one or more
options will automatically accelerate in connection with a Hostile Take-Over.
Any such option shall become exercisable, immediately prior to the effective
date of such Hostile Take-Over, for all of the shares of Common Stock at the
time subject to that option and may be exercised for any or all of those shares
as fully-vested shares of Common Stock. In addition, the Plan Administrator may
at any time provide that one or more of the Corporation's repurchase rights
shall terminate automatically upon the consummation of such Hostile Take-Over.
Alternatively, the Plan Administrator may condition such automatic acceleration
and termination upon an Involuntary Termination of the Optionee's Service within
a designated period (not to exceed eighteen (18) months) following the effective
date of such Hostile Take-Over.  Each option so accelerated shall remain
exercisable for fully-vested shares until the expiration or sooner termination
of the option term.

                                      10.
<PAGE>
 
          H.   The portion of any Incentive Option accelerated in connection
with a Change in Control or Hostile Take Over shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded.  To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a Non-
Statutory Option under the Federal tax laws.

     IV.  STOCK APPRECIATION RIGHTS

          The Plan Administrator may, subject to such conditions as it may
determine, grant to selected Optionees stock appreciation rights which will
allow the holders of those rights to elect between the exercise of the
underlying option for shares of Common Stock and the surrender of that option in
exchange for a distribution from the Corporation in an amount equal to the
excess of (a) the Option Surrender Value of the number of shares for which the
option is surrendered over (b) the aggregate exercise price payable for such
shares.  The distribution may be made in shares of Common Stock valued at Fair
Market Value on the option surrender date, in cash, or partly in shares and
partly in cash, as the Plan Administrator shall in its sole discretion deem
appropriate.

                     SALARY INVESTMENT OPTION GRANT PROGRAM
                     --------------------------------------

     I.   OPTION GRANTS

          The Primary Committee may implement the Salary Investment Option Grant
Program for one or more calendar years beginning after the Underwriting Date and
select the Section 16 Insiders and other highly compensated Employees eligible
to participate in the Salary Investment Option Grant Program for each such
calendar year.  Each selected individual who elects to participate in the Salary
Investment Option Grant Program must, prior to the start of each calendar year
of participation, file with the Plan Administrator (or its designate) an
irrevocable authorization directing the Corporation to reduce his or her base
salary for that calendar year by an amount not less than Ten Thousand Dollars
($10,000.00) nor more than Fifty Thousand Dollars ($50,000.00).  The Primary
Committee shall have complete discretion to determine whether to approve the
filed authorization in whole or in part.  To the extent the Primary Committee
approves the authorization, the individual who filed that authorization shall be
granted an option under the Salary Investment Grant Program on the first trading
day in January for the calendar year for which the salary reduction is to be in
effect.

     II.  OPTION TERMS

          Each option shall be a Non-Statutory Option evidenced by one or more
documents in the form approved by the Plan Administrator; provided, however,
                                                          --------          
that each such document shall comply with the terms specified below.

          A.   EXERCISE PRICE.
               -------------- 

          1.  The exercise price per share shall be thirty-three and one-third
percent (33-1/3%) of the Fair Market Value per share of Common Stock on the
option grant date.

          2.  The exercise price shall become immediately due upon exercise of
the option and shall be payable in one or more of the alternative forms
authorized under the Discretionary Option Grant Program.  Except to the extent
the sale and remittance procedure specified thereunder is utilized, payment of
the exercise price for the purchased shares must be made on the Exercise Date.

          B.   NUMBER OF OPTION SHARES.  The number of shares of Common Stock
               -----------------------                                       
subject to the option shall be determined pursuant to the following formula
(rounded down to the nearest whole number):

               X = A / (B x 66-2/3%), where

               A is the dollar amount of the approved reduction in the
               Optionee's base salary for the calendar year, and

               B is the Fair Market Value per share of Common Stock on the
               option grant date.

          C.   EXERCISE AND TERM OF OPTIONS.  The option shall become
               ----------------------------                          
exercisable in a series of twelve (12) successive equal monthly installments
upon the Optionee's completion of each calendar month of Service in the calendar
year for which the salary reduction is in effect.  Each option shall have a
maximum term of ten (10) years measured from the option grant date.

          D.   CESSATION OF SERVICE.  Each option outstanding at the time of the
               --------------------                                             
Optionee's cessation of Service shall remain exercisable, for any or all of the
shares for which the option is exercisable at the time of such cessation of
Service, until the earlier of (i) the expiration of the option term or (ii) the
                   -------                                                     
expiration of the three (3)-year period following the Optionee's cessation of
Service.  To the extent the option is held by the Optionee at the time of his or
her death, the option may be exercised by his or her Beneficiary.  However, the
option shall, immediately upon the Optionee's cessation of Service, terminate
and cease to remain outstanding with respect to any and all shares of Common
Stock for which the option is not otherwise at that time exercisable.

     III. CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Change in Control or Hostile Take-Over while
the Optionee remains in Service, each outstanding option shall automatically
accelerate so that each such option shall, immediately prior to the effective
date of the Change in Control or Hostile Take-Over, become fully exercisable
with respect to the total number of shares of Common Stock at the time subject
to such option and may be exercised for any or all of those shares as fully-
vested shares of Common Stock.  Each such option accelerated in connection with
a Change in Control shall terminate upon the Change in Control, except to the
extent assumed by the successor corporation (or parent thereof) or otherwise
continued in full force and effect pursuant to the terms of the Change in
Control.  Each such option accelerated in connection with a Hostile Take-Over
shall remain exercisable until the expiration or sooner termination of the
option term.

                                      13.
<PAGE>
 
          B.  Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding options.  The Optionee shall in return be entitled to a
cash distribution from the Corporation in an amount equal to the excess of (i)
the Option Surrender Value of the shares of Common Stock at the time subject to
each surrendered option (whether or not the Optionee is otherwise at the time
vested in those shares) over (ii) the aggregate exercise price payable for such
shares.  Such cash distribution shall be paid within five (5) days following the
surrender of the option to the Corporation.

     IV.  REMAINING TERMS

          The remaining terms of each option granted under the Salary Investment
Option Grant Program shall be the same as the terms in effect for options made
under the Discretionary Option Grant Program.

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

     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening options.  Shares
of Common Stock may also be issued under the Stock Issuance Program pursuant to
share right awards which entitle the recipients to receive those shares upon the
attainment of designated performance goals or Service requirements.  Each such
award shall be evidenced by one or more documents which comply with the terms
specified below.

          A.   PURCHASE PRICE.
               -------------- 

               1.     The purchase price per share of Common Stock subject to
direct issuance shall be fixed by the Plan Administrator.

               2.     Subject to the provisions of Section II of Article Seven,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                    (i)     cash or check made payable to the Corporation, or

                    (ii)    past services rendered to the Corporation (or any 
     Parent or Subsidiary).

          B.   VESTING/ISSUANCE PROVISIONS.
               --------------------------- 

               1.     The Plan Administrator may issue shares of Common Stock
which are fully and immediately vested upon issuance or which are to vest in one
or more installments over the Participant's period of Service or upon attainment
of specified performance objectives. Alternatively, the Plan Administrator may
issue share right awards which shall entitle the recipient to receive a
specified number of vested shares of Common Stock upon the attainment of one or
more performance goals or Service requirements established by the Plan
Administrator.

               2.     Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to his or her unvested
shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

                                      15.
<PAGE>
 
               3.     The Participant shall have full stockholder rights with
respect to the issued shares of Common Stock, whether or not the Participant's
interest in those shares is vested. Accordingly, the Participant shall have the
right to vote such shares and to receive any regular cash dividends paid on such
shares.

               4.     Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock, or should the performance
objectives not be attained with respect to one or more such unvested shares of
Common Stock, then those shares shall be immediately surrendered to the
Corporation for cancellation, and the Participant shall have no further
stockholder rights with respect to those shares. To the extent the surrendered
shares were previously issued to the Participant for consideration paid in cash
or cash equivalent (including the Participant's purchase-money indebtedness),
the Corporation shall repay to the Participant the cash consideration paid for
the surrendered shares and shall cancel the unpaid principal balance of any
outstanding purchase-money note of the Participant attributable to the
surrendered shares.

               5.     The Plan Administrator may waive the surrender and
cancellation of one or more unvested shares of Common Stock (or other assets
attributable thereto) which would otherwise occur upon the cessation of the
Participant's Service or the non-attainment of the performance objectives
applicable to those shares. Such waiver shall result in the immediate vesting of
the Participant's interest in the shares of Common Stock as to which the waiver
applies. Such waiver may be effected at any time, whether before or after the
Participant's cessation of Service or the attainment or non-attainment of the
applicable performance objectives.

               6.     Outstanding share right awards shall automatically
terminate, and no shares of Common Stock shall actually be issued in
satisfaction of those awards, if the performance goals or Service requirements
established for such awards are not attained. The Plan Administrator, however,
shall have the authority to issue shares of Common Stock in satisfaction of one
or more outstanding share right awards as to which the designated performance
goals or Service requirements are not attained.

     II.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   All of the Corporation's outstanding repurchase rights shall
terminate automatically, and all the shares of Common Stock subject to those
terminated rights shall immediately vest in full, in the event of any Change in
Control, except to the extent (i) those repurchase rights are assigned to the
successor corporation (or parent thereof) or otherwise continue in full force
and effect pursuant to the terms of the Change in Control or (ii) such
accelerated vesting is precluded by other limitations imposed by the Plan
Administrator at the time the repurchase right is issued.

          B.   The Plan Administrator may at any time provide for the automatic
termination of one or more of those outstanding repurchase rights and the
immediate vesting of the shares of Common Stock subject to those terminated
rights upon (i) a Change in Control or Hostile Take-Over or (ii) an Involuntary
Termination of the Participant's Service within a

                                      16.
<PAGE>
 
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control or Hostile Take-Over in which those repurchase
rights are assigned to the successor corporation (or parent thereof) or
otherwise continue in full force and effect.

     III. SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

non-employee Board member for at least six (6) months.

               1.     The exercise price per share shall be equal to one hundred

          C.   OPTION TERM.  Each option shall have a term of ten (10) years
               -----------                                                  
measured from the option grant date.

          D.   EXERCISE AND VESTING OF OPTIONS.  Each option shall be
               -------------------------------                       
immediately exercisable for any or all of the option shares.  However, any
shares purchased under the option shall be subject to repurchase by the
Corporation, at the exercise price paid per share, upon the Optionee's cessation
of Board service prior to vesting in those shares.  Each initial 10,000-share
option shall vest, and the Corporation's repurchase right shall lapse, in a
series of four (4) successive equal annual installments upon the Optionee's
completion of each year of Board

                                      18.

               --------------------------                                 
govern the exercise of any options outstanding at the time of the Optionee's
cessation of Board service:

               (i)     Any option outstanding at the time of the Optionee's
     cessation of Board service for any reason shall remain exercisable for a
     twelve (12)-month period following the date of such cessation of Board
     service, but in no event shall such option be exercisable after the
     expiration of the option term.

               (ii)    Any option exercisable in whole or in part by the
     Optionee at the time of death may be subsequently exercised by his or her
     Beneficiary.

               (iii)   Following the Optionee's cessation of Board service, the
     option may not be exercised in the aggregate for more than the number of
     shares in which the Optionee was vested on the date of such cessation of
     Board service.  Upon the expiration of the applicable exercise period or
     (if earlier) upon the expiration of the option term, the option shall
     terminate and cease to be outstanding for any vested shares for which the
     option has not been exercised.  However, the option shall, immediately upon
     the Optionee's cessation of Board service, terminate and cease to be
     outstanding for any and all shares in which the Optionee is not otherwise
     at that time vested.

               (iv)    However, should the Optionee cease to serve as a Board
     member by reason of death or Permanent Disability, then all shares at the
     time subject to the option shall immediately vest so that such option may,
     during the twelve (12)-month exercise period following such cessation of
     Board service, be exercised for all or any portion of those shares as
     fully-vested shares of Common Stock.

     II.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Change in Control or Hostile Take-Over, the
shares of Common Stock at the time subject to each outstanding option but not
otherwise vested shall automatically vest in full so that each such option may,
immediately prior to the effective date of such Change in Control the Hostile
Take-Over, be exercised for all or any portion of those shares as fully-vested
shares of Common Stock.  Each such option accelerated in connection with a
Change in Control shall terminate upon the Change in Control, except to the
extent assumed by the successor corporation (or parent thereof) or otherwise
continued in full force and effect pursuant to the terms of the Change in
Control.  Each such option accelerated in connection with

                                      19.
<PAGE>
 
a Hostile Take-Over shall remain exercisable until the expiration or sooner
termination of the option term.

          B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Change in Control or Hostile
Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding options.  The Optionee shall in return be entitled to a
cash distribution from the Corporation in an amount equal to the excess of (i)
the Option Surrender Value of the shares of Common Stock at the time subject to
each surrendered option (whether or not the Optionee is otherwise at the time
vested in those shares) over (ii) the aggregate exercise price payable for such
shares.  Such cash distribution shall be paid within five (5) days following the
surrender of the option to the Corporation.

          D.   Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted to apply to the number and class of
securities which would have been issuable to the Optionee in consummation of
such Change in Control had the option been exercised immediately prior to such
Change in Control.  Appropriate adjustments shall also be made to the exercise
price payable per share under each outstanding option, provided the aggregate
                                                       --------

               ----------------------------                                  
service for any reason (other than death or Permanent Disability) while one or
more of his or her options are outstanding, then each such option shall remain
exercisable, for any or all of the shares for which the option is exercisable at
the time of such cessation of Board service, until the earlier of (i) the
                                                       -------           
expiration of the option term or (ii) the expiration of the three (3)-year

such option outstanding at the time of such cessation of Board service shall
immediately terminate and cease to remain outstanding with respect to any and
all shares of Common Stock for which the option is not otherwise at that time
exercisable.

          E.   DEATH OR PERMANENT DISABILITY.  Should the Optionee's service as

of his or her death, the option may be exercised by his or her Beneficiary.

     III. CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Change in Control or Hostile Take-Over while
the Optionee remains in Board service, each outstanding option shall
automatically accelerate so that each such option shall, immediately prior to
the effective date of the Change in Control or Hostile Take-Over, become fully
exercisable with respect to the total number of shares of Common Stock at the
time subject to such option and may be exercised for any or all of those shares
as fully-vested shares of Common Stock.  Each such option accelerated in
connection with a Change in Control shall terminate upon the Change in Control,
except to the extent assumed by the successor corporation (or parent thereof) or
otherwise expressly continued in full force and effect pursuant to the terms of
the Change in Control.  Each such option accelerated in connection with a
Hostile Take-Over shall remain exercisable until the expiration or sooner
termination of the option term.

shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Taxes) with
an aggregate Fair Market Value equal to the percentage of the Taxes (not to
exceed one hundred percent (100%)) designated by the holder.

     IV.  EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective immediately upon the Plan
Effective Date.  However, the Salary Investment Option Grant Program and
Director Fee Option Grant Program shall not be implemented until such time as
the Primary Committee or the Board may deem appropriate.  Options may be granted
under the Discretionary Option Grant or Automatic Option Grant Program at any
time on or after the Plan Effective Date.  However, no options granted under the
Plan may be exercised, and no shares shall be issued under the Plan, until the
Plan is approved by the Corporation's stockholders.  If such stockholder
approval is not obtained within twelve (12) months after the Plan Effective
Date, then all options previously granted under this Plan shall terminate and
cease to be outstanding, and no further options shall be granted and no shares
shall be issued under the Plan.

          B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further options or direct stock issuances shall be made under the
Predecessor Plan after the Section 12 Registration Date.   All options
outstanding under the Predecessor Plan on the Section 12 Registration Date shall
be incorporated into the Plan at that time and shall be treated as outstanding
options under the Plan.  However, each outstanding option so incorporated shall
continue to be governed solely by the terms of the documents evidencing such
option, and no provision of the Plan shall be deemed to affect or otherwise
modify the rights or obligations of the holders of such incorporated options
with respect to their acquisition of shares of Common Stock.

          C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Changes in Control, may, in the Plan Administrator's discretion, be extended
to one or more options incorporated from the Predecessor Plan which do not
otherwise contain such provisions.

          D.   The Plan shall terminate upon the earliest of (i) _____________],
                                                 --------       
(ii) the date on which all shares available for issuance under the Plan shall
have been issued as fully-vested shares or (iii) the termination of all
outstanding options in connection with a Change in Control. Upon such plan
termination, all outstanding options and unvested stock issuances shall
thereafter continue to have force and effect in accordance with the provisions
of the documents evidencing such grants or issuances.

     V.   AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to stock options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and Salary Investment Option Grant Programs and
shares of Common Stock may be issued under the Stock Issuance Program that are
in each instance in excess of the number of shares then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock available
for issuance under the Plan.  If such stockholder approval is not obtained
within twelve (12) months after the date the first such excess issuances are
made, then (i) any unexercised options granted on the basis of such excess
shares shall terminate and cease to be outstanding and (ii) the Corporation
shall promptly refund to the Optionees and the Participants the exercise or
purchase price paid for any excess shares issued under the Plan and held in
escrow, together with interest (at the applicable Short Term Federal Rate) for
the period the shares were held in escrow, and such shares shall thereupon be
automatically cancelled and cease to be outstanding.

     VI.  USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     VII. REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

     VIII.  NO EMPLOYMENT/SERVICE RIGHTS

            Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific duration
or interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                       1998 EMPLOYEE STOCK PURCHASE PLAN
                       ---------------------------------


     I.   PURPOSE OF THE PLAN

          This Employee Stock Purchase Plan is intended to promote the interests
of GeoCities, a California corporation, by providing eligible employees with the
opportunity to acquire a proprietary interest in the Corporation through
participation in a payroll-deduction based employee stock purchase plan designed
to qualify under Section 423 of the Code.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.  ADMINISTRATION OF THE PLAN

          The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423.  Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

     III. STOCK SUBJECT TO PLAN

          A.   The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market.  The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed Three
Hundred Thousand (300,000) shares.

          B.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and class of securities issuable under
the Plan, (ii) the maximum number and class of securities purchasable per
Participant and in the aggregate on any one Purchase Date and (iii) the number
and class of securities and the price per share in effect under each outstanding
purchase right in order to prevent the dilution or enlargement of benefits
thereunder.
<PAGE>
 
     IV.  PURCHASE PERIODS

          A.   Shares of Common Stock shall be offered for purchase under the
Plan through a series of successive purchase periods until such time as (i) the
maximum number of shares of Common Stock available for issuance under the Plan
shall have been purchased or (ii) the Plan shall have been sooner terminated.

          B.   Each purchase period shall have a duration of six (6) months.
Purchase periods shall run from the first business day in February each year to
the last business day in July of the same year and from the first business day
in August each year to the last business day in January of the following year.
However, the first purchase period shall commence at the Effective Time and
terminate on the last business day in January 1999.

     V.   ELIGIBILITY

          A.   Each individual who is an Eligible Employee on the start date of
any purchase period under the Plan may enter that purchase period on such start
date.

          B.   To participate in the Plan for a particular purchase period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before the start date of the purchase period.

     VI.  PAYROLL DEDUCTIONS

          A.   The payroll deduction authorized by the Participant for purposes
of acquiring shares of Common Stock under the Plan may be any multiple of one
percent (1%) of the Base Salary paid to the Participant during each purchase
period, up to a maximum of ten percent (10%).  The deduction rate so authorized
shall continue in effect throughout the purchase period.  the Participant may
not increase his or her rate of payroll deduction during a purchase period.
However, the Participant may, at any time during the purchase period, reduce his
or her rate of payroll deduction to become effective as soon as possible after
filing the appropriate form with the Plan Administrator.  The Participant may
not, however, effect more than one (1) such reduction per purchase period.

          B.   Payroll deductions shall begin on the first pay day following the
start date of the purchase period and shall (unless sooner terminated by the
Participant) continue through the pay day ending with or immediately prior to
the last day of the purchase period.  The amounts so collected shall be credited
to the Participant's book account under the Plan, but no interest shall be paid
on the balance from time to time outstanding in such account.  The amounts
collected from the Participant shall not be required to be held in any
segregated account or trust fund and may be commingled with the general assets
of the Corporation and used for general corporate purposes.

                                      2.
<PAGE>
 
          C.   Payroll deductions shall automatically cease upon the termination
of the Participant's purchase right in accordance with the provisions of the
Plan.

          D.   The Participant's acquisition of Common Stock under the Plan on
any Purchase Date shall neither limit nor require the Participant's acquisition
of Common Stock on any subsequent Purchase Date.

     VII. PURCHASE RIGHTS

          A.   GRANT OF PURCHASE RIGHT.  A Participant shall be granted a
               -----------------------                                   
separate purchase right on the start date of each purchase period in which he or
she participates.  The purchase right shall provide the Participant with the
right to purchase shares of Common Stock on the Purchase Date upon the terms set
forth below.  The Participant shall execute a stock purchase agreement embodying
such terms and such other provisions (not inconsistent with the Plan) as the
Plan Administrator may deem advisable.

          Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

          B.   EXERCISE OF THE PURCHASE RIGHT.  Each purchase right shall be
               ------------------------------                               
automatically exercised on the Purchase Date, and shares of Common Stock shall
accordingly be purchased on behalf of each Participant (other than Participants
whose payroll deductions have previously been refunded pursuant to the
Termination of Purchase Right provisions below) on each such Purchase Date.  The
purchase shall be effected by applying the Participant's payroll deductions for
the purchase period ending on such Purchase Date to the purchase of whole shares
of Common Stock at the purchase price in effect for that purchase period.

          C.   PURCHASE PRICE.  The purchase price per share at which Common
               --------------                                               
Stock will be purchased on the Participant's behalf on each Purchase Date shall
be equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value
                                             -----                             
per share of Common Stock on the start date of the purchase period or (ii) the
Fair Market Value per share of Common Stock on that Purchase Date.

          D.   NUMBER OF PURCHASABLE SHARES.  The number of shares of Common
               ----------------------------                                 
Stock purchasable by a Participant on each Purchase Date shall be the number of
whole shares obtained by dividing the amount collected from the Participant
through payroll deductions during the purchase period ending with that Purchase
Date by the purchase price in effect for that Purchase Date.  However, the
maximum number of shares of Common Stock purchasable per Participant on any one
Purchase Date shall not exceed One Thousand (1,000) shares, subject to periodic
adjustments in the event of certain changes in the Corporation's capitalization.
In addition, the maximum aggregate number of shares of Common Stock purchasable
by all Participants on any

                                      3.
<PAGE>
 
one Purchase Date shall not exceed Twelve Thousand Five Hundred (12,500) shares,
subject to periodic adjustments in the event of certain changes in the
Corporation's capitalization.

          E.   EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not applied to
               -------------------------                                        
the  purchase of shares of Common Stock on any Purchase Date because they are
not sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date.  However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable on the Purchase Date
shall be promptly refunded.

          F.   TERMINATION OF PURCHASE RIGHT.  The following provisions shall
               -----------------------------                                 
govern the termination of outstanding purchase rights:

               (i)   A Participant may, at any time prior to the last day of the
     purchase period, terminate his or her outstanding purchase right by filing
     the appropriate form with the Plan Administrator (or its designate), and no
     further payroll deductions shall be collected from the Participant with
     respect to the terminated purchase right.  Any payroll deductions collected
     during the purchase period in which such termination occurs shall, at the
     Participant's election, be immediately refunded or held for the purchase of
     shares on the next Purchase Date.  If no such election is made at the time
     such purchase right is terminated, then the payroll deductions collected
     with respect to the terminated right shall be refunded as soon as possible.

               (ii)  The termination of such purchase right shall be
     irrevocable, and the Participant may not subsequently rejoin the purchase
     period for which the terminated purchase right was granted. In order to
     resume participation in any subsequent purchase period, such individual
     must re-enroll in the Plan (by making a timely filing of the prescribed
     enrollment forms) on or before the start date of the new purchase period.

               (iii) Should the Participant cease to remain an Eligible
     Employee for any reason (including death, disability or change in status)
     while his or her purchase right remains outstanding, then that purchase
     right shall immediately terminate, and all of the Participant's payroll
     deductions for the purchase period in which the purchase right so
     terminates shall be immediately refunded.  However, should the Participant
     cease to remain in active service by reason of an approved unpaid leave of
     absence, then the Participant shall have the right, exercisable up until
     the last business day of the purchase period in which such leave commences,
     to (a) withdraw all the payroll deductions collected to date on his or her
     behalf for that purchase period or (b) have such funds held for the
     purchase of shares on his or her behalf on the next scheduled Purchase
     Date.  In no event, however, shall any further payroll deductions be
     collected on the Participant's behalf during such leave.  Upon the
     Participant's return to active

                                      4.
<PAGE>
 
     service (i) within ninety (90) days following the commencement of such
     leave or, (ii) prior to the expiration of any longer period for which such
     Participant's right to reemployment with the Corporation is guaranteed by
     either statute or contract, his or her payroll deductions under the Plan
     shall automatically resume at the rate in effect at the time the leave
     began.  However, should the Participant's leave of absence exceed ninety
     (90) days and his or her re-employment rights not be guaranteed by either
     statute or contract, then the Participant's status as an Eligible Employee
     will be deemed to terminate on the ninety-first (91st) day of that leave,
     and such Participant's purchase right for the purchase period in which that
     leave began shall thereupon terminate.  An individual who returns to active
     employment following such a leave shall be treated as a new Employee for
     purposes of the Plan and must, in order to resume participation in the
     Plan, re-enroll in the Plan (by making a timely filing of the prescribed
     enrollment forms) on or before the start date of the new purchase period.

          G.   CHANGE IN CONTROL.  Each outstanding purchase right shall
               -----------------                                        
automatically be exercised, immediately prior to the effective date of any
Change in Control by applying the payroll deductions of each Participant for the
purchase period in which such Change in Control occurs to the purchase of whole
shares of Common Stock at a purchase price per share equal to eighty-five
percent (85%) of the lower of (i) the Fair Market Value per share of Common
                     -----                                                 
Stock on the start date of the purchase period in which such Change in Control
occurs or (ii) the Fair Market Value per share of Common Stock immediately prior
to the effective date of such Change in Control.  However, the applicable
limitation on the number of shares of Common Stock purchasable per Participant
shall continue to apply to any such purchase, but not the limitation applicable
to the maximum number of shares of Common Stock purchasable in the aggregate.

          The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Change in Control, and
Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Change in Control.

          H.   PRORATION OF PURCHASE RIGHTS.  Should the total number of shares
               ----------------------------                                    
of Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

          I.   ASSIGNABILITY.  The purchase right shall be exercisable only by
               -------------                                                  
the Participant and shall not be assignable or transferable by the Participant.

          J.   STOCKHOLDER RIGHTS.  A Participant shall have no stockholder
               ------------------                                          
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased

                                      5.
<PAGE>
 
on the Participant's behalf in accordance with the provisions of the Plan and
the Participant has become a holder of record of the purchased shares.

   VIII.  ACCRUAL LIMITATIONS

          A.   No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right granted under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

          B.   For purposes of applying such accrual limitations to the purchase
rights granted under the Plan, the following provisions shall be in effect:

               (i)  The right to acquire Common Stock under each outstanding
     purchase right shall accrue on the Purchase Date in effect for the period
     on which such right is granted.

               (ii) No right to acquire Common Stock under any outstanding
     purchase right shall accrue to the extent the Participant has already
     accrued in the same calendar year the right to acquire Common Stock under
     one (1) or more other purchase rights at a rate equal to Twenty-Five
     Thousand Dollars ($25,000) worth of Common Stock (determined on the basis
     of the Fair Market Value per share on the date or dates of grant) for each
     calendar year such rights were at any time outstanding.

          C.   If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular purchase period, then the payroll
deductions which the Participant made during that purchase period with respect
to such purchase right shall be promptly refunded.

          D.   In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

          A.   The Plan was adopted by the Board on July 6, 1998 and shall
become effective at the Effective Time, provided no purchase rights granted

under the Plan shall be exercised, and no shares of Common Stock shall be issued
hereunder, until (i) the Plan shall have been approved by the stockholders of
the Corporation and (ii) the Corporation shall have complied with all applicable
requirements of the 1933 Act (including the registration of the shares of Common
Stock issuable under the Plan on a Form S-8 registration statement filed with
the Securities and Exchange Commission), all applicable listing requirements of
any stock exchange (or the Nasdaq National Market, if applicable) on which the
Common Stock is listed for trading and all other applicable requirements
established by law or regulation.  In the event such stockholder approval is not
obtained, or such compliance is not effected, within twelve (12) months after
the date on which the Plan is adopted by the Board, the Plan shall terminate and
have no further force or effect, and all sums collected from Participants during
the initial purchase period hereunder shall be refunded.

          B.   Unless sooner terminated by the Board, the Plan shall terminate
upon the earliest of (i) the last business day in July 2008, (ii) the date on
         --------                                                            
which all shares available for issuance under the Plan shall have been sold
pursuant to purchase rights exercised under the Plan or (iii) the date on which
all purchase rights are exercised in connection with a Corporate Transaction.
No further purchase rights shall be granted or exercised, and no further payroll
deductions shall be collected, under the Plan following such termination.

     X.   AMENDMENT/TERMINATION OF THE PLAN

          A.   The Board may alter, amend, suspend or terminate the Plan at any
time to become effective immediately following the close of any purchase period.
However, the Plan may be amended or terminated immediately upon Board action, if
and to the extent necessary to assure that the Corporation will not recognize,
for financial reporting purposes, any compensation expense in connection with
the shares of Common Stock offered for purchase under the Plan, should the
financial accounting rules applicable to the Plan at the Effective Time be
subsequently revised so as to require the recognition of compensation expense in
the absence of such amendment or termination.

          B.   In no event may the Board effect any of the following amendments
or revisions to the Plan without the approval of the Corporation's stockholders:
(i) increase the number of shares of Common Stock issuable under the Plan or the
maximum number of shares purchasable per Participant on any one Purchase Date,
except for permissible adjustments in the event of certain changes in the
Corporation's capitalization, (ii) alter the purchase price formula so as to
reduce the purchase price payable for the shares of Common Stock purchasable
under the Plan or (iii) modify eligibility requirements for participation in the
Plan.

terminate such person's employment  at any time for any reason, with or without
cause.

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

               (a) Exhibits E-1 and E-2 contain, respectively, an accurate and

                                       4
<PAGE>
 
complete description of all registered and unregistered trademarks and
tradenames in or related to the Company Products, and a list of all licenses and
other agreements relating thereto.  Exhibit E-3 sets forth a list of all
licenses and other agreements with third parties (the "Third Party Licenses")
relating to any software, copyrights, technology, know-how or processes that the
Company has licensed or is otherwise authorized by such third parties to use,
market, distribute or incorporate into products distributed by the Company (such
software, technology, know-how and processes are collectively referred to as the
"Third Party Technology").  The Company (i) owns all right, title and interest
in and to or has obtained licenses to use all technology, intellectual property,
software tools, copyrights, know-how, processes, patents, trademarks, trade
secrets, tradenames and other proprietary rights (collectively, "Rights") used
in or necessary for the conduct of its business as conducted to the date hereof
(the "Business") and (ii) will, prior to entering areas of new business
currently being contemplated, own or obtain all Rights used in or necessary for
the conduct of its business as so contemplated, including without limitation
(with respect to both clauses (i) and (ii) above), the technology and all
proprietary rights developed or discovered in connection with or contained in
the Company's products (the "Company Products"), free and clear of all
liabilities, charges, liens, pledges, mortgages, restrictions, adverse claims,
security interests, rights of others and encumbrances (including, without
limitation, distribution rights) (all of which are referred to as "Proprietary
Rights").  The foregoing representation and warranty as it relates to Third
Party Technology is limited to the Company's interest pursuant to the Third
Party Licenses, all of which are valid and enforceable and in full force and
effect and which grant the Company such right to Third Party Technology as are
employed in or necessary to the Business of the Company as conducted or proposed
to be conducted.  All of the Company's registered patents, trademarks and
copyrights in any of the Company Products and applications therefor, if any, are
valid and in full force and effect, and consummation of the transactions
contemplated hereby will not alter or impair any such rights.  No claims have
been asserted against the Company (and to the best knowledge of the Company
there are no claims which are likely to be asserted against the Company or which
have been asserted against others) by any person challenging the Company's use
or distribution of any patents, trademarks, tradenames, copyrights, trade
secrets, software, technology, know-how or processes utilized by the Company
(inclUding, without limitation, the Third Party Technology) or challenging or
questioning the validity or effectiveness of any license or agreement relating
thereto (including, without limitation, the Third Party Licenses).  To the best
knowledge of the Company, none of the Company Products nor the use of any
patents, trademarks, tradenames, copyrights, software, technology, know-how or
processes by the Company in its current Business infringes on the rights of,
constitutes misappropriation of, or in any way involves unfair competition with
respect to, any proprietary information or intangible property right of any
third person or entity, including without limitation, any patent, trade secret,
copyright, trademark or tradename.

               (b) The Company has not granted any third party any right to
manufacture, reproduce, distribute, market or exploit any of the Company
Products or any adaptations, translations or derivative works based on the
Company Products or any portion thereof.  Except with respect to the rights of
third parties to the Third Party Technology, no 

                                       5
<PAGE>
 
third party has any right to manufacture, reproduce, distribute, market or
exploit any works or materials of which any of the Company products are a
"derivative work" as that term is defined in the United States Copyright Act,
Title 17, U.S.C. Section 101.

               (c) All designs, drawings, specifications, source code, object
code, documentation, flow charts and diagrams incorporating, embodying or
reflecting any of the Company Products (the "Company Components"), if any,
constitute original creations of and were written, developed and created solely
and exclusively by employees of the Company without the assistance of any third
party or entity or were created by third parties who assigned ownership of their
rights to the Company in valid and enforceable consultant confidentiality and
invention assignment agreements. The Company has at all times used commercially
reasonable efforts to treat the Company Products and the Company Components as
containing trade secrets and has not disclosed or otherwise dealt with such
items in such a manner as to cause the loss of such trade secrets by release
into the public domain.

               (d) No employee of the Company is in violation of any term of any
employment contract, patent disclosure agreement, confidentiality agreement or
any other contract or agreement relating to the relationship of any such
employee with the Company or, to the best knowledge of the Company, any other
party because of the nature of the business conducted by the Company or proposed
to be conducted by the Company.

               (e) Notwithstanding the foregoing, the Company states and the
Purchasers acknowledge and agree that the Company is a service provider on the
electronic network commonly known as the Internet, and that the Business is
unique in that the Company has not created, nor does it own, the content of each
Personal Home Page and third-party advertising that may be found within the
Company Products ("Excluded Rights").   The parties agree that the term
Proprietary Rights does not include, and the Company hereby disclaims the
representations and warranties of this Section 3.6 (except for the
representation in Section 3.6(a) as to assertion of claims against the Company
or claims which to the knowledge of the Company are likely to be asserted) as to
Excluded Rights found within the Company Products.  Personal Home Pages are
subject to the Company's Personal Home Page Policy, and the Company's rights as
to the Personal Home Pages are set forth in the Personal Home Page Policy (a
copy of which has been provided to special counsel to the Purchasers).  The
Company does not own or control the content of any Personal Home Page,  except
as set forth in the Personal Home Page Policy.  The Purchasers further
acknowledge and agree that the Internet is global in scope, and that the
representations and warranties of the Company made in this Section 3.6 are
limited to the laws of the United States.   The Company is unaware, however, of
any third party having rights in the Proprietary Rights under the laws of any
foreign jurisdiction that are superior to those of the Company, or of any
violation by the Company of the laws of any foreign jurisdiction.

          3.7  Compliance with Other Instruments, None Burdensome, etc.  The
               --------------------------------------------------------     
Company is not in violation of any term of its Restated Articles or Bylaws, nor
is the Company in violation of or in default in any material respect under the
terms of any mortgage, 

                                       6
<PAGE>
 
indenture, contract, agreement, instrument, judgment or decree, the violation of
which would have a material adverse effect on the Company, and to the best
knowledge of the Company is not in violation of any order, statute, rule or
regulation applicable to the Company. The execution, delivery and performance of
and compliance with this Agreement or the Rights Agreement, the issuance and
sale of the Preferred Shares and the issuance of the Common Shares upon
conversion of the Preferred Shares will not (a) result in any such violation, or
(b) be in conflict with or constitute a default under any such term, or (c)
result in the creation of any mortgage, pledge, lien, encumbrance or charge upon
any of the properties or assets of the Company pursuant to any such term. To the
best knowledge of the Company, there is no such term which adversely affects, or
in the future may materially adversely affect, the business, prospects,
conditions, affairs or operations of the Company or any of its properties or
assets.

          3.8  Proprietary Agreements.  Each officer, director, employee and
               ----------------------                                       
consultant of the Company has executed an agreement regarding confidentiality
and proprietary information, the form of which has been approved by special
counsel to the Purchasers. The Company is not aware that any of its officers,
directors or employees is in violation thereof and will use its best efforts to
prevent any such violation.  David Bohnett and John Rezner and other key
technical employees have executed an agreement regarding the assignment of
inventions, the form of which has been approved by special counsel to the
Purchasers.  The Company is not aware that any of its officers, directors or
employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of his or her best efforts to promote the interests of the Company or
that would conflict with the Company's business as conducted or as proposed to
be conducted or that would prevent any such employee from assigning inventions
to the Company.  Neither the execution nor delivery of this Agreement or the
Rights Agreement, nor the carrying on of the Company's business as proposed,
will, to the Company's best knowledge, conflict with or result in a breach of
the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any of such employees is now
obligated.   The Company does not believe that it is or will be necessary for
the Company to utilize any inventions of any of its employees made prior to
their employment by the Company.

          3.9  Litigation, etc.  There is no action, proceeding or investigation
               ----------------                                                 
pending against the Company or its officers or directors, or to the best
- --------                                                                
knowledge of the Company, against employees or consultants of the Company (or,
to the best knowledge of the Company, any basis therefor or threat thereof): (1)
which might result, either individually or in the aggregate, in (a) any material
adverse change in the business, prospects, conditions, affairs or operations of
the Company or in any of its properties or assets, or (b) any material
impairment of the right or ability of the Company to carry on its business as
now conducted or as proposed to be conducted, or (c) any material liability on
the part of the Company; or (2) which questions the validity of this Agreement,
the Rights Agreement or any action taken or to be taken in connection herewith,
including in each case, without limitation, actions pending or threatened
involving the prior employment of any of the Company's employees, the use in
connection with the Company's business of any information or techniques
allegedly proprietary 

                                       7
<PAGE>
 
to any of its former employees, or their obligations under any agreements with
prior employers. The Company is not a party to or subject to the provisions of
any order, writ, injunction, judgment or decree of any court or government
agency or instrumentality. There is no action, suit, proceeding or investigation
by the Company currently pending or which the Company currently intends to
initiate.

          3.10 Governmental Consent, etc.   No consent, approval or
               --------------------------                          
authorization of or designation, registration, declaration or filing with any
governmental authority on the part of the Company is required in connection
with:  (a) the valid execution and delivery of this Agreement or the Rights
Agreement, or (b) the offer, sale or issuance of the Preferred Shares, or the
issuance of the Common Shares issuable upon conversion of the Preferred Shares,
or (c) the obtaining of the consents, permits and waivers specified in
subsection 5.1(b)  hereof, except the filing of the Restated Articles and, if

qualifications, if required, will have been timely filed or obtained after the
sale of the Preferred Shares.

          3.11 Offering.  In reliance on the representations and warranties of
               --------                                                       
the Purchasers in Section 4 hereof, the offer, sale and issuance of the
Preferred Shares in conformity with the terms of this Agreement will not result
in a violation of the requirements of Section 5 of the Securities Act of 1933,

requirements of the Law or other applicable blue sky laws.

          3.12 Taxes.  The Company has filed all tax returns that are required

to have been filed with appropriate federal, state, county and local
governmental agencies or instrumentalities, except where the failure to do so
would not in the aggregate result in additional liability totaling $25,000 or
more.  The Company has paid or established reserves for all income, franchise
and other taxes, assessments, governmental charges, penalties, interest and
fines due and payable by it on or before the First Closing.  There is no pending
dispute with any taxing authority relating to any of such returns and the
Company has no knowledge of any proposed liability for any tax to be imposed
upon the properties or assets of the Company.  There is no tax lien, whether
imposed by any federal, state or local taxing authority, outstanding against the
assets, properties or business of the Company.   Neither the Company nor any of
its present or former shareholders has ever filed an election pursuant to
Section 1362 of the Internal Revenue Code of 1986, as amended (the "Code"), that

complete description of all registered and unregistered trademarks and
tradenames in or related to the Company Products, and a list of all licenses and
other agreements relating thereto. Exhibit E-3 sets forth a list of all licenses
                                   -----------                                  
and other agreements with third parties (the "Third Party Licenses") relating to
any software, copyrights, technology, know-how or processes that the Company has
licensed or is otherwise authorized by such third parties to use, market,
distribute or incorporate into products distributed by the Company (such
software, technology, know-how and processes are collectively referred to as the
"Third Party Technology"). The Company (i) owns all right, title and interest in
and to or has obtained licenses to use all technology, intellectual property,
software tools, copyrights, know-how, processes, patents, trademarks, trade
secrets, tradenames and other proprietary rights (collectively, "Rights") used
in or necessary for the conduct of its business as conducted to the date hereof
(the "Business") and (ii) will, prior to entering areas of new business
currently being contemplated, own or obtain all Rights used in or necessary for
the conduct of its business as so contemplated, including without limitation
(with respect to both clauses (i) and (ii) above), the technology and all
proprietary rights developed or discovered in connection with or contained in
the Company's products (the "Company Products"), free and clear of all
liabilities, charges, liens, pledges, mortgages, restrictions, adverse claims,
security interests, rights of others and encumbrances (including, without
limitation, distribution rights) (all of which are referred to as "Proprietary
Rights"). The foregoing representation and warranty as it relates to Third Party
Technology is limited to the Company's interest pursuant to the Third Party
Licenses, all of which are valid and enforceable and in full force and effect
and which grant the Company such right to Third Party Technology 

                                       4
<PAGE>
 
as are employed in or necessary to the Business of the Company as conducted or
proposed to be conducted. All of the Company's registered patents, trademarks
and copyrights in any of the Company Products and applications therefor, if any,
are valid and in full force and effect, and consummation of the transactions
contemplated hereby will not alter or impair any such rights. No claims have
been asserted against the Company (and to the best knowledge of the Company
there are no claims which are likely to be asserted against the Company or which
have been asserted against others) by any person challenging the Company's use
or distribution of any patents, trademarks, tradenames, copyrights, trade
secrets, software, technology, know-how or processes utilized by the Company
(including, without limitation, the Third Party Technology) or challenging or
questioning the validity or effectiveness of any license or agreement relating
thereto (including, without limitation, the Third Party Licenses). To the best
knowledge of the Company, none of the Company Products nor the use of any
patents, trademarks, tradenames, copyrights, software, technology, know-how or
processes by the Company in its current Business infringes on the rights of,
constitutes misappropriation of, or in any way involves unfair competition with
respect to, any proprietary information or intangible property right of any
third person or entity, including without limitation, any patent, trade secret,
copyright, trademark or tradename.

              (b)  The Company has not granted any third party any right to
manufacture, reproduce, distribute, market or exploit any of the Company
Products or any adaptations, Translations or derivative works based on the
Company Products or any portion thereof. Except with respect to the rights of
third parties to the Third party Technology, no third party has any right to
manufacture, reproduce, distribute, market or exploit any works or materials of
which any of the Company Products are a "derivative work" as that term is
defined in the United States Copyright act, Title 17, U.S.C. Section 101.

              (c)  All designs, drawings, specifications, source code, object
code, documentation, flow charts and diagrams incorporating, embodying or
reflecting any of the Company Products (the "Company Components"), if any,
constitute original creations of and were written, developed and created solely
and exclusively by employees of the Company without the assistance of any third
party or entity or were created by third parties who assigned ownership of their
rights to the Company in valid and enforceable consultant confidentiality and
invention assignment agreements. The Company has at all times used commercially
reasonable efforts to treat the Company Products and the Company Components as
containing trade secrets and has not disclosed or otherwise dealt with such
items in such a manner as to cause the loss of such trade secrets by release
into the public domain.

              (d)  No employee of the Company is in violation of any term of any
employment contract, patent disclosure agreement, confidentiality agreement or
any other contract or agreement relating to the relationship of any such
employee with the Company or, to the best knowledge of the Company, any other
party because of the nature of the business conducted by the Company or proposed
to be conducted by the Company.

              (e)  Notwithstanding the foregoing, the Company states and the 
Purchasers acknowledge and agree that the Company is a service provider on the
electronic network commonly known as the Internet, and that the Business is
unique in that the Company has not created, nor does it own, the content of each
Personal Home Page and third-party 

                                       5
<PAGE>
 
advertising that may be found within the Company Products ("Excluded Rights").
The parties agree that the term Proprietary Rights does not include, and the
Company hereby disclaims the representations and warranties of this Section 3.6
(except for the representation in Section 3.6(a) as to assertion of claims
against the Company or claims which to the knowledge of the Company are likely
to be asserted) as to Excluded Rights found within the Company Products.
Personal Home Pages are subject to the Company's Personal Home Page Policy, and
Company's rights as to the Personal Home Pages are set forth in the Personal
Home Page Policy (a copy of which has been provided to special counsel to the
Purchasers). The Company does not own or control the content of any Personal
Home Page, except as see forth in the Personal Home Page Policy. The Purchasers
further acknowledge and agree that the Internet is global in scope, and that the
representations and warranties of the Company made in this Section 3.6 are
limited to the laws of the United States. The Company is unaware, however, of
any third party having rights in the Proprietary Rights under the laws of any
foreign jurisdiction that are superior to those of the Company, or of any
violation by the Company of the laws of any foreign jurisdiction.

        3.7  Compliance with Other Instruments, None Burdensome, etc.  The
             --------------------------------------------------------
Company is not in violation of any term of its Restated Articles or Bylaws, nor
is the Company in violation of or in default in any material respect under the
terms of any mortgage, indenture, contract, agreement, instrument, judgment or
decree, the violation of which would have a material adverse effect on the
Company, and to the best knowledge of the Company is not in violation of any
order, statute, rule or regulation applicable to the Company. The execution,
delivery and performance of and compliance with this Agreement or the Rights
Agreement, [he issuance and sale of the Preferred Shares and the issuance of the
Common Shares upon conversion of the Preferred Shares will not (a) result in any
such violation, or (b) be in conflict with or constitute a default under any
such term, or (c) result in the creation of any mortgage, pledge, lien,
encumbrance or charge upon any of the properties or assets of the Company
pursuant to any such term. To the best knowledge of the Company, there is no
such term which adversely affects, or in the future may materially adversely
affect, the business, prospects, conditions, affairs or operations of the
Company or any of its properties or assets.

        3.8  Proprietary Agreements. Each officer, director, employee and
             ----------------------        
consultant of the Company has executed an agreement regarding confidentiality
and proprietary information, the form of which has been approved by special
counsel to the Purchasers. The Company is not aware that any of its officers,
directors or employees is in violation thereof and will use its best efforts to
prevent any such violation. David Bohnett and John Rezner and other key
technical employees have executed an agreement regarding the assignment of
inventions, the form of which has been approved by special counsel to the
Purchasers. The Company is not aware that any of its officers, directors or
employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of his or her best efforts to promote the interests of the Company or
that would conflict with the Company's business as conducted or as proposed to
be conducted or that would prevent any such employee from assigning inventions
to the Company. Neither the execution nor delivery of this Agreement or the
Rights Agreement, nor the carrying on of the Company's business as proposed,
will, to the Company's best knowledge, conflict with or result in a breach of
the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any of such employees is now
obligated. The Company does not believe that it is or

                                       6
<PAGE>
 
will be necessary for the Company to utilize any inventions of any of its
employees made prior to their employment by the Company.

         3.9  Litigation, etc.  There is no action, proceeding or investigation 
              ----------------  
pending against the Company or its officers or directors, or to the best
knowledge of the Company, against employees or consultants of the Company (or,
to the best knowledge of the Company, any basis therefor or threat thereof): (1)
which might result, either individually or in the aggregate, in (a) any material
adverse change in the business, prospects, conditions, affairs or operations of
the Company or in any of its properties or assets, or (b) any material
impairment of the right or ability of the Company to carry on its business as
now conducted or as proposed to be conducted, or (c) any material liability on
the part of the Company; or (2) which questions the validity of this Agreement,
the Rights Agreement or any action taken or to be taken in connection herewith,
including in each case, without limitation, actions pending or threatened
involving the prior employment of any of the Company's employees, the use in
connection with the Company's business of any information or techniques
allegedly proprietary to any of its former employees, or their obligations under
any agreements with prior employers. The Company is not a party to or subject to
the provisions of any order, writ, injunction, judgment or decree of any court
or government agency or instrumentality. There is no action, suit, proceeding or
investigation by the Company currently pending or which the Company currently
intends to initiate.

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

               --------   
the Purchasers in Section 4 hereof, the offer, sale and issuance of the
Preferred Shares in conformity with the terms of this Agreement will not result
in a violation of the requirements of Section 5 of the Securities Act of 1933,
as amended (the "Securities Act") or the qualification or registration

engage in activities which would result in a conflict of interest with the
Company. The Company's obligations hereunder include, but are not limited to,

ability and attention to the business of the Company (provided, however, the
Company's employees may engage in other professional activity if such activity

employees from engaging or participating in any business that is in competition
with the business of the Company.

              ------------------------   
efforts to qualify as a "Qualified Small Business" as defined in Section 1202(d)

of CMG @Ventures, Chase Venture Capital Associates, L.P., The fl@tiron Fund LLC,

to prevent any employee from violating the confidentiality and proprietary

employees.

              --------------------   
repurchase any shares of its Common Stock or Series C Preferred Stock so long as
the Preferred Shares are outstanding, except that the Company shall be entitled

Company or the proposed transfer by an employee, director or consultant of
shares of its Common Stock or Series C Preferred Stock, or pursuant to the terms

Purchaser's expense, to visit and inspect the Company's properties, to examine

and accounts with its officers, all at such reasonable times as may be requested

pursuant to this Section 6.8 to provide access to any information which it
reasonably considers to be a trade secret or similar confidential information.

         6.9  Reserve for Conversion Shares.  The Company shall at all times 
              -----------------------------   
reserve and keep available out of its authorized but unissued shares of Common
Stock, for the purpose of effecting the conversion of the Preferred Shares and
otherwise complying with the terms of this Agreement, such number of its duly
authorized shares of Common Stock as shall be sufficient to

                                      17
<PAGE>
 
effect the conversion of the Preferred Shares from time to time outstanding or
otherwise to comply with the terms of this Agreement. If at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of the Preferred Shares or otherwise to comply with the
terms of this Agreement, the Company will forthwith take such corporate action
as may be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes. The
Company will obtain any authorization, consent, approval or other action by or
make any filing with any court or administrative body that may be required under
applicable state securities laws in connection with the issuance of shares of

change in beneficiary and shall not borrow against any such policy. If requested
by Purchasers holding at least a majority of the outstanding Preferred Shares,
the Company will add one designee of the Purchasers as a notice parry for each
such policy and shall request that the issuer of each policy provide such
designee with ten (10) days' notice before such policy is terminated (for
failure to pay premiums or otherwise) or assigned or before any change is made
in the beneficiary thereof.

         6.11  Transactions with Affiliates.  Except for transactions 
               ----------------------------   
contemplated by this Agreement or as otherwise approved by the Board of

unanimous approval of the members of the Compensation Committee (as defined in

options previously granted to William Bohnett and Stanley Newman to purchase

per annum from the date of such grant and (ii) the shares issuable upon exercise
of such option are subject to repurchase, first by the Company and second, by
the holders of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock, rata, upon termination of
employment or upon the attempted transfer of such shares by a holder thereof.

         6.13  Committees.  The Company shall continue to maintain a

         3.6  Proprietary Rights.
              ------------------ 

              (a)  Exhibits El and E-2 contain, respectively, an accurate and
                   -------------------
complete description of all registered and unregistered trademarks and trade
names in or related to the Company Products, and a list of all licenses and
other agreements relating thereto. Exhibit E-3 sets forth a list of all licenses
                                   -----------
and other agreements with third parties (the "Third Party Licenses") relating to
any software, copyrights, technology, know-how or processes that the Company has
licensed or is otherwise authorized by such third parties to use, market,
distribute or incorporate into products distributed by the Company (such
software, technology, know-how and processes are collectively referred to as the
"Third Party Technology"). The Company (i) owns all right, title and interest in
and to or has obtained licenses to use all technology, intellectual property,
software tools, copyrights, know-how, processes, patents, trademarks, trade
secrets, trade names and other proprietary rights (collectively, "Rights") used
in or necessary for the conduct of its business as conducted to the date hereof
(the "Business") and (ii) will, prior to entering areas of new business
currently being contemplated, own or obtain all Rights used in or necessary for
the conduct of its business as so contemplated, including without limitation
(with respect to both clauses (i) and (ii) above), the technology and all
proprietary rights developed or discovered in connection with or contained in
the Company's products (the "Company Products"), free and clear of all
liabilities, charges, liens, pledges, mortgages, restrictions, adverse claims,
security interests, rights of others and encumbrances (including, without
limitation, distribution rights) (all of which are referred to as "Proprietary
Rights"). The foregoing representation and warranty as it relates to Third Party
Technology is limited to the Company's interest pursuant to the Third Party
Licenses, all of which are valid and enforceable and in full force and effect
and which grant the Company such right to Third Party Technology as are employed
in or necessary to the Business of the Company as conducted or proposed to be
conducted. All of the Company's registered patents, trademarks and copyrights in
any of the Company Products and applications therefor, if any, are valid and in
full force and effect, and consummation of the transactions contemplated hereby
will not alter or impair any such rights. No claims have been asserted against
the Company (and to the best knowledge of the Company there are no claims which
are likely to be asserted against the Company or which have been asserted
against others) by any person challenging the Company's use or distribution of
any patents, trademarks, trade names, copyrights, trade secrets, software,
technology, know-how or processes utilized by the Company (including, without
limitation, the Third Party Technology) or challenging or questioning the
validity or effectiveness of any license or agreement relating thereto
(including, without limitation, the Third Party Licenses). To the best knowledge
of the Company, none of the Company Products nor the use of any patents,
trademarks, trade names, copyrights, software, technology, know-how or processes
by the Company in its current Business infringes on the rights of, constitutes
misappropriation of, or in any way involves unfair 

                                      -5-
<PAGE>
 
competition with respect to, any proprietary information or intangible property
right of any third person or entity, including without limitation, any patent,
trade secret, copyright, trademark or trade name.

                   (b)  The Company has not granted any third party any right to
manufacture, reproduce, distribute, market or exploit any of the Company
Products or any adaptations, translations or derivative works based on the
Company Products or any portion thereof Except with respect to the rights of
third parties to the Third Party Technology, no third party has any right to
manufacture, reproduce, distribute, market or exploit any works or materials of
which any of the Company Products are a "derivative work" as that term is
defined in the United States Copyright Act, Title 17, U.S.C. Section 101.

                   (c)  All designs, drawings, specifications, source code,
object code, documentation, flow charts and diagrams incorporating, embodying or
reflecting any of the Company Products (the "Company Components"), if any,
constitute original creations of and were written, developed and created solely
and exclusively by employees of the Company without the assistance of any third
party or entity or were created by third parties who assigned ownership of their
rights to the Company in valid and enforceable consultant confidentiality and
invention assignment agreements. The Company has at all times used commercially
reasonable efforts to treat the Company Products and the Company Components as
containing trade secrets and has not disclosed or otherwise dealt with such
items in such a manner as to cause the loss of such trade secrets by release
into the public domain.

                   (d)  No employee of the Company is in violation of any term
of any employment contract, patent disclosure agreement, confidentiality
agreement or any other contract or agreement relating to the relationship of any
such employee with the Company or, to the best knowledge of the Company, any
other party because of the nature of the business conducted by the Company or
proposed to be conducted by the Company.

                   (e)  Notwithstanding the foregoing, the Company states and
the Purchasers acknowledge and agree that the Company is a service provider on
the electronic network commonly known as the Internet, and that the Business is
unique in that the Company has not created, nor does it own, the content of each
Personal Home Page and third-party advertising that may be found within the
Company Products ("Excluded Rights"). The parties agree that the term
Proprietary Rights does not include, and the Company hereby disclaims the
representations and warranties of this Section 3.6 (except for the
representation in Section 3.6(a) as to assertion of claims against the Company
or claims which to the knowledge of the Company are likely to be asserted) as to
Excluded Rights found within the Company Products. Personal Home Pages are
subject to the Company's Personal Home Page Policy, and the Company's rights as
to the Personal Home Pages are set forth in the Personal Home Page Policy (a
copy of which has been provided to Venture Law Group). The Company does not own
or control the content of any Personal Home Page, except as set forth in the
Personal Home Page Policy. The Purchasers further acknowledge and agree that the
Internet is global in scope, and that the representations and warranties of the
Company made in this Section 3.6 are limited to the laws of the United States.
The Company is unaware, however, of any third party having rights in the
Proprietary Rights under the laws of any foreign jurisdiction that are superior
to those of the Company, or of any violation by the Company of the laws of any
foreign jurisdiction.

              3.7  Compliance with Other Instruments, None Burdensome, etc. The
                   -------------------------------------------------------
Company is not in violation of any term of its Restated Articles or Bylaws, nor
is the Company in violation of or in default in any material respect under the
terms of any mortgage, indenture, contract, agreement, instrument, judgment or
decree, the violation of which would have a material adverse effect on the
Company, and to the best knowledge of the Company is not in violation of any
order, statute, rule or regulation applicable to the Company. The execution,
delivery and performance of and compliance with the Transaction Agreements, the
issuance and sale of the Preferred Shares and the issuance of the Common Shares
upon conversion of the Preferred Shares or other shares of Preferred Stock will
not (a) result in any such violation, or (b) be in conflict with or constitute a
default under any such term, or (c) result in the creation of any mortgage,
pledge, lien, encumbrance or charge upon any of the properties or assets of the
Company pursuant to any such term. To the best knowledge of the Company, there
is no such term which adversely affects, or in the future may materially
adversely affect, the business, prospects, conditions, affairs or operations of
the Company or any of its properties or assets.

              3.8  Proprietary Agreements. Each officer, director, employee and
                   ----------------------
consultant of the Company has executed an agreement regarding confidentiality
and proprietary information. The Company is not aware that any of its officers,
directors or employees is in violation thereof and will use its best efforts to
prevent any such violation. All employees have executed an agreement regarding
the assignment of inventions, the form of which has been approved by Venture Law
Group. The Company is not aware that any of its officers, directors or employees
is obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement, or subject to any judgment, decree or order of
any court or administrative agency, that would interfere with the use of his or
her best efforts to promote the interests of the Company or that would conflict
with the Company's business as conducted or as proposed to be conducted or that
would prevent any such employee from assigning inventions to the Company.
Neither the execution nor delivery of this Agreement or the Rights Agreement,
nor the carrying on of the Company's business as proposed, will, to the
Company's best knowledge, conflict with or result in a breach of the terms,
conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees is now obligated. The
Company does not believe that it is or will be necessary for the Company to
utilize any inventions of any of its employees made prior to their employment by
the Company.

              3.9  Litigation, etc. There is no action, proceeding or
                   ---------------
investigation pending against the Company or its officers or directors, or to
the best knowledge of the Company, against employees or consultants of the
Company (or, to the best knowledge of the Company, any basis therefor or threat
thereof: (1) which might result, either individually or in the aggregate, in (a)
any material adverse change in the business, prospects, conditions, affairs or
operations of the Company or in any of its properties or assets, or (b) any
material impairment of the right or ability of the Company to carry on its
business as now conducted or as proposed to be conducted, or (c) any material
liability on the part of the Company; or (2) which questions the validity of
this Agreement, the Rights Agreement or any action taken or to be taken in
connection herewith, including in each case, without limitation, actions pending
or threatened involving the prior employment of any of the Company's employees,
the use in connection with the Company's business of any information or
techniques allegedly proprietary to any of its former employees, or their
obligations under any agreements with prior employers. The Company is not a
party to or subject to the provisions of any order, writ, injunction, judgment
or

          8.  Registration of Yahoo Stock.
              ---------------------------

              8.1  Registration.
                   ------------ 

                   (a)  Registrable Shares. For purposes of this Agreement,
                        ------------------
"Registrable Shares" shall mean any and all shares of Yahoo Stock delivered at
any of the Closings by any of the Purchasers as payment of the purchase price
for the Shares to the Company and the Sellers (individually, a "Holder", and
collectively, the "Holders"), including any shares of Yahoo Stock that have been
sold or otherwise transferred by the Company or the Sellers who initially
received such Yahoo Stock. The transferees of such Yahoo Stock shall be entitled
to the same rights under this Section 8.1 as the initial Holder from which the
Registrable Shares were received and shall be deemed a Holder for the purposes
of this Section 8.1.

                   (b)  Required Registration. As soon as practicable following
                        ---------------------
the signing of this Agreement (and no later than January 8, 1998), Yahoo shall
prepare and file with the Commission a registration statement on Form S-3 (or
such successor or other appropriate form) under the Securities Act with respect
to the Registrable Shares (the "Registration Statement"), use its best efforts
to cause such Registration Statement to become effective as soon as practicable
thereafter and effect all such registrations, qualifications and compliances
(including, without limitation, obtaining appropriate qualifications under
applicable state securities or "blue sky" laws and compliance with any other
applicable governmental requirements or regulations) to permit or facilitate the
public resale of Registrable Shares (provided however that Yahoo shall not be
required in connection therewith to qualify to do business or to file a general
consent to service of process in any such state or jurisdiction), in each case
so that such Registration Statement and all other such registrations,
qualifications and compliances may become effective as soon as practical
thereafter.

                   (c)  Effectiveness; Suspension Right.
                        ------------------------------- 

                        (i)  Yahoo will use its best efforts to maintain the
effectiveness of the Registration Statement and other applicable registrations,
qualifications and compliances until at least the expiration of six (6) months
from the Third Closing Date (the "Registration Effective Period"), and from time
to time will amend or supplement the Registration Statement and the prospectus
contained therein as and to the extent necessary to comply with the Securities
Act, the Exchange Act and any applicable state securities statute or regulation,
subject to the following limitations and qualifications.

                        (ii) Following the date on which the Registration
Statement is first declared effective, the Holders will be permitted (subject in
all cases to Section 8.2 below) to offer and sell Registrable Shares during the
Registration Effective Period in the manner described in the Registration
Statement provided that the Registration Statement remains effective and has not
been suspended.

                                      -20-
<PAGE>
 
                        (iii) Notwithstanding any other provision of this
Section 8.1 but subject to Section 8.2, Yahoo shall have the right at any time
to require that all Holders suspend further open market offers and sales of
Registrable Shares whenever, and for so long as, in the reasonable judgment of
Yahoo after consultation with counsel there is or may be in existence material
undisclosed information or events with respect to Yahoo (the "Suspension
Right"). In the event Yahoo exercises the Suspension Right, such suspension will
continue for the period of time reasonably necessary for disclosure to occur at
a time that is not detrimental to Yahoo and its shareholders or until such time
as the information or event is no longer material, each as determined in good
faith by Yahoo after consultation with counsel. Yahoo will promptly give the
Holders notice of any such suspension and will use all reasonable efforts to
minimize the length of the suspension.

                   (d)  Expenses. The costs and expenses to be borne by Yahoo
                        --------
for purposes of this Section 8.1 shall include, without limitation, printing
expenses (including such number of prospectuses for circulation by each selling
Holder as may be reasonably requested by such selling Holder), legal fees and
disbursements of counsel for Yahoo, "blue sky" expenses, accounting fees and
filing fees, but shall not include underwriting commissions or similar charges,
legal fees and disbursements of counsel for the selling Holders.

                   (e)  Indemnification.
                        --------------- 

                        (i)  To the extent permitted by law, Yahoo will
indemnify and hold harmless each Holder, any underwriter (as defined in the
Securities Act) for such Holder, each such Holders' and underwriters' officers,
directors, shareholders or partners and each person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation"): (A) any untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (B) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (C) any violation or alleged violation by Yahoo of
the Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law; and Yahoo will pay to each such Holder, each such underwriter
(and each holder's and underwriter's respective officers, directors,
shareholders or partners), and to each such controlling person, any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this Section 8.1 (e)(i) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of Yahoo; nor shall
Yahoo be liable in any such case for any such loss, claim, damage, liability, or
action to the extent that it arises out of or is based upon (a) a Violation
which occurs in reliance upon and in conformity with written information
furnished expressly for use in the Registration Statement by any such Holder, or
(b) a Violation that would not have occurred if such Holder had delivered to the
purchaser the 

                                      -21-
<PAGE>
 
version of the Prospectus most recently provided by Yahoo to the Holder as of
the date of such sale.

                        (ii)  To the extent permitted by law, each selling
Holder will indemnify and hold harmless Yahoo, each of its directors, each of
its officers who has signed the Registration Statement, each person, if any, who
controls Yahoo within the meaning of the Securities Act, any underwriter, any
other Holder selling securities pursuant to the Registration Statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation
(which includes without limitation the failure of the Holder to comply with the
prospectus delivery requirements under the Securities Act, and the failure of
the Holder to deliver the most current prospectus provided by Yahoo prior to
such sale), in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in the Registration Statement or such
Violation is caused by the Holder's failure to deliver to the purchaser of the
Holder's Registrable Shares a prospectus (or amendment or supplement thereto)
that had been made available to the Holder by Yahoo; and each such Holder will
pay any legal or other expenses reasonably incurred by any person intended to be
indemnified pursuant to this Section 8.1(e)(ii) in connection with investigating
or defending any such loss, claim, damage, liability, or action; provided,
however, that the indemnity agreement contained in this Section 8.1(e)(ii) shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld. The aggregate
indemnification and contribution liability of each Holder under this Section
8.1(e)(ii) shall not exceed the net proceeds received by such Holder in
connection with sale of shares pursuant to the Registration Statement.

                        (iii) Each person entitled to indemnification under this
Section 8.1(e) (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought and shall permit the Indemnifying Party to assume the defense of any such
claim and any litigation resulting therefrom, provided that counsel for the
Indemnifying Party who conducts the defense of such claim or any litigation
resulting therefrom shall be approved by the Indemnified Party (whose approval
shall not unreasonably be withheld), and the Indemnified Party may participate
in such defense at such party's expense, and provided further that the failure
of any Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 8.1 unless the
Indemnifying Party is materially prejudiced thereby. No Indemnifying Party, in
the defense of any such claim or litigation, shall (except with the consent of
each Indemnified Party, which consent shall not be unreasonably withheld)
consent to entry of any judgment or enter into any settlement that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation. Each Indemnified Party shall furnish such information
regarding itself or the claim in question as an Indemnifying Party may
reasonably request in writing and as shall be reasonably required in connection
with the defense of such claim and litigation resulting therefrom.

                                      -22-
<PAGE>
 
                        (iv) To the extent that the indemnification provided for
in this Section 8.1(e) is held by a court of competent jurisdiction to be
unavailable to an Indemnified Party with respect to any loss, liability, claim,
damage or expense referred to herein, then the Indemnifying Party, in lieu of
indemnifying such Indemnified Party hereunder, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such loss, liability,
claim, damage or expense in such proportion as is appropriate to reflect the
relative fault of the Indemnifying Party on the one hand and of the Indemnified
Party on the other in connection with the statements or omissions which resulted
in such loss, liability, claim, damage or expense, as well as any other relevant
equitable considerations. The relative fault of the Indemnifying Party and of
the Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Indemnifying Party or by the Indemnified Party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

              8.2  Procedures for Sale of Shares Under Registration Statement.
                   ---------------------------------------------------------- 

                   (a)  Notice and Approval. If any Holder shall propose to sell
                        -------------------
any Registrable Shares pursuant to the Registration Statement, it shall notify
Yahoo of its intent to do so (including the proposed manner and timing of all
sales) at least two (2) full trading days prior to such sale, and the provision
of such notice to Yahoo shall conclusively be deemed to reestablish and
reconfirm an agreement by such Holder to comply with the registration provisions
set forth in this Agreement. Unless otherwise specified in such notice, such
notice shall be deemed to constitute a representation that any information
previously supplied by such Holder in writing expressly for inclusion in the
Registration Statement (as the same may have been superseded by subsequent such
information supplied by such Holder in writing) is accurate as of the date of
such notice. At any time within such two (2) trading-day period, Yahoo may
refuse to permit the Holder to resell any Registrable Shares pursuant to the
Registration Statement; provided, however, that in order to exercise this right,
Yahoo must deliver a certificate in writing to the Holder to the effect that a
delay in such sale is necessary because a sale pursuant to the Registration
Statement in its then-current form without the addition of material, non-public
information about Yahoo, could constitute a violation of the federal securities
laws. Notwithstanding the foregoing, Yahoo will ensure that in any event (i) the
Holders shall have at least twenty (20) trading days available to sell
Registrable Shares during each calendar quarter for a period of six (6) months
immediately following the Third Closing Date (with such minimum time period
being prorated for partial quarters to the extent reasonably practical to do
so), and (ii) the Holders shall have at least ten (10) consecutive trading days
available to sell Registrable Shares after each of the Second and Third Closing
Dates, commencing immediately after each Closing Date.

                   (b)  Delivery of Prospectus. For any offer or sale of any of
                        ----------------------
the Registrable Shares by a Holder in a transaction that is not exempt under the
Securities Act, the Holder, in addition to complying with any other federal
securities laws, shall deliver a copy of the final prospectus (or amendment of
or supplement to such prospectus) of Yahoo covering the Registrable Shares in
the form furnished to the Holder by Yahoo to the purchaser of any of the
Registrable Shares on or before the settlement date for the purchase of such
Registrable Shares.

                   (c)  Copies of Prospectuses. Subject to the provisions of
                        ----------------------
this Section 8.2, when a Holder is entitled to sell and gives notice of its
intent to sell Registrable Shares pursuant to the Registration Statement, Yahoo
shall, within two (2) trading days following the request, furnish to such Holder
a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such Registrable Shares, such prospectus shall not as of the date
of delivery to the Holder include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing.
