OUR BUSINESS

    We operate ABOUT.COM, a network of more than 650 highly-targeted,
topic-specific web sites. Our network is differentiated by the high quality and
depth of content we provide to users through the efforts of knowledgeable human
guides who manage the sites, the volume of sites in our network and the
consistency of site structure and design across the network. The sites provide
high-quality original articles, moderated forums and chat rooms, newsletters,
easy access to related sites, tools, and functionality within the ABOUT.COM
network and extensive hand-picked links to web sites outside of ABOUT.COM. We
pre-screen, train and monitor our guides to ensure quality and consistency
across our network.

    Our network has been the fastest growing property among the top 25 Internet
properties ranked by Media Metrix since we launched the About.com brand in May
1999. According to Media Metrix, approximately 8.9 million unique users visited
ABOUT.COM in August 1999, making ABOUT.COM the number one
news/information/entertainment Internet property in terms of audience reach and
the fifteenth largest Internet property overall.

    We believe that the design of our network provides an attractive advertising
and electronic commerce platform for reaching highly concentrated groups of
users. Because our network is organized into sections and channels of related
sites, we provide advertisers and electronic commerce marketers the ability to
access specific audiences through our highly targeted sites or use our sections,
channels or network to reach broader audiences.

OUR GROWTH STRATEGY

    Our objective is to enhance our position as the leading Internet network of
topic-specific web sites. The key elements of our strategy include:

    - Enhancing channels

    - Increasing traffic

    - Continuing to build brand awareness

    - Maximizing revenues from highly-targeted advertising

CORPORATE INFORMATION

                                  RISK FACTORS

    ANY INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU
SHOULD CONSIDER CAREFULLY THE FOLLOWING INFORMATION ABOUT THESE RISKS, TOGETHER
WITH THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS, BEFORE YOU DECIDE TO
BUY OUR COMMON STOCK. IF ANY OF THE EVENTS DESCRIBED IN THE FOLLOWING RISK
FACTORS ACTUALLY OCCURS, OUR BUSINESS, RESULTS OF OPERATIONS OR FINANCIAL
CONDITION WOULD LIKELY SUFFER. IN THIS CASE, THE MARKET PRICE OF OUR COMMON
STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF THE MONEY YOU PAID TO BUY
OUR COMMON STOCK.

BECAUSE WE HAVE ONLY BEEN IN BUSINESS FOR A SHORT PERIOD OF TIME, THERE IS
  LIMITED INFORMATION UPON WHICH YOU CAN EVALUATE OUR BUSINESS.

    We were incorporated in June 1996 and launched our network in April 1997.
Accordingly, you can only evaluate our business based on our limited operating
history. As a young company, we face risks and uncertainties relating to our
ability to successfully implement our business plan. If we are unsuccessful in
addressing these risks and uncertainties, our business, results of operations
and financial condition will be materially adversely affected.

WE HAVE LOST MONEY EVERY QUARTER AND EVERY YEAR, AND WE EXPECT TO LOSE MONEY IN
  THE FUTURE.

    IF OUR REVENUES DO NOT INCREASE SUBSTANTIALLY, WE MAY NEVER BECOME
PROFITABLE. We have not generated enough revenues to exceed the substantial
amounts we have spent to create, launch and enhance ABOUT.COM and to grow our
business. Even if we do achieve profitability, we may not sustain or increase
profitability on a quarterly or annual basis in the future.

    A PORTION OF OUR HISTORICAL REVENUES HAVE BEEN DERIVED FROM BARTER
AGREEMENTS. Approximately 10% of our revenues in 1998 and approximately 7% of
our revenues in the first six months of 1999 were derived from agreements where
we traded advertisements on ABOUT.COM in exchange for advertisements on other
web sites without receiving any cash payments. We expect that these barter
revenues will continue to account for up to 10% of our total annual revenues in
the future.

    OUR COSTS OF REVENUES COMBINED WITH OUR OPERATING EXPENSES HAVE EXCEEDED OUR
REVENUES FOR ALL QUARTERS. We have historically funded our operations by selling
our stock and not by generating income from our business. At June 30, 1999, our
accumulated deficit was $59.3 million. We expect to continue to lose money for
the foreseeable future because we plan to continue to incur significant
expenses.

FLUCTUATIONS IN OUR OPERATING RESULTS MAY NEGATIVELY IMPACT OUR STOCK PRICE.

    Our quarterly operating results may fluctuate significantly in the future
due to a variety of factors that could affect our revenues or our expenses in
any particular quarter. It is possible that in some future periods our results
of operations may be below the expectations of public market analysts and
investors. In this event, the price of our common stock is likely to fall.

    You should not rely on our results of operations during any particular
quarter as an indication of our results for a full year or any other quarter.
Factors that may affect our quarterly results include:

    - the demand for advertising on ABOUT.COM;

    - the number of Internet users on, and the frequency of their use of,
      ABOUT.COM, since our advertising revenues are typically based on user
      traffic;

    - our ability to attract and retain advertisers and electronic commerce
      partners;

    - fees we may pay for distribution or content or other costs we may incur as
      we expand our operations;

                                       4
<PAGE>
    - our ability to meet the minimum number of advertisements that we are
      required to deliver to users by many of our advertising contracts, since
      our failure to do this would result in our deferring recognition of the
      related revenues and would reduce our available advertising inventory in
      subsequent periods;

    - changes in rates paid for advertising on ABOUT.COM; and

    - the timing and amount of our costs related to advertising sales and
      marketing efforts.

    Our operating expenses are based in part on our expectations of our future
revenues and are relatively fixed in the short term. Given our limited operating
history and our difficulties in accurately estimating the user traffic
historically experienced on our website, user traffic on our website is
difficult to forecast accurately. Consequently, since revenues from Internet
advertising will make up a significant amount of our revenues for the
foreseeable future, our revenues are difficult to forecast accurately. In
particular, we intend to continue to expend significant amounts to build and
enhance brand awareness of ABOUT.COM. We may be unable to adjust spending
quickly enough to offset any unexpected revenue shortfall. If we have a
shortfall in revenues in relation to our expenses, or if our expenses precede
increased revenues, then our results of operations and financial condition would
be materially adversely affected.

WE WILL ONLY BE ABLE TO EXECUTE OUR BUSINESS PLAN IF INTERNET USAGE GROWS.

    Our business would be adversely affected if Internet usage does not grow.
Internet usage may be inhibited for any of the following reasons:

    - the Internet infrastructure may not be able to support the demands placed
      on it, and its performance and reliability may decline as usage grows;

    - security and authentication concerns with respect to the transmission over
      the Internet of confidential information, such as credit card numbers, and
      attempts by unauthorized computer users, so-called hackers, to penetrate
      online security systems; and

    - privacy concerns, including those related to the ability of web sites to
      gather user information without the user's knowledge or consent.

WE WILL ONLY BE ABLE TO EXECUTE OUR BUSINESS PLAN IF INTERNET ADVERTISING
  INCREASES.

    OUR BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITION WOULD BE
MATERIALLY ADVERSELY AFFECTED IF THE INTERNET ADVERTISING MARKET DEVELOPS MORE
SLOWLY THAN WE EXPECT OR IF WE ARE UNSUCCESSFUL IN INCREASING OUR ADVERTISING
REVENUES. Revenues from Internet advertising will make up a significant amount
of our revenues for the foreseeable future. Since the Internet advertising
market is new and rapidly evolving, we cannot yet gauge its effectiveness as
compared to traditional advertising media.

    THE ADOPTION OF INTERNET ADVERTISING, PARTICULARLY BY THOSE ENTITIES THAT
HAVE HISTORICALLY RELIED UPON TRADITIONAL MEDIA FOR ADVERTISING, REQUIRES THE
ACCEPTANCE OF A NEW WAY OF CONDUCTING BUSINESS, EXCHANGING INFORMATION AND
ADVERTISING PRODUCTS AND SERVICES. Advertisers that have traditionally relied
upon other advertising media may be reluctant to advertise on the Internet.
These businesses may find Internet advertising to be less effective than
traditional advertising media for promoting their products and services. Many
potential advertising and electronic commerce partners have little or no
experience using the Internet for advertising purposes. Consequently, they may
allocate only limited portions of their advertising budgets to Internet
advertising.

    ADVERTISERS AND ELECTRONIC COMMERCE MARKETERS MAY NOT ADVERTISE ON ABOUT.COM
OR MAY PAY LESS FOR ADVERTISING ON ABOUT.COM IF THEY DO NOT BELIEVE THAT THEY
CAN RELIABLY MEASURE THE EFFECTIVENESS OF INTERNET ADVERTISING OR THE
DEMOGRAPHICS OF THE USER VIEWING THEIR ADVERTISEMENTS. We use both internal
measurements and measurements provided to us by third parties. If these third
parties are unable to

                                       5
<PAGE>
continue to provide these services, we would have to perform them ourselves or
obtain them from another provider. This could cause us to incur additional costs
or cause interruptions in our business while we are replacing these services. In
addition, we are implementing additional systems designed to record demographic
data on our customers. If we do not implement these systems successfully, we may
not be able to accurately evaluate the demographic characteristics of our
customers. Moreover, "filter" software programs that limit or prevent
advertising from being delivered to an Internet user's computer are available.
Widespread adoption of this software could adversely affect the commercial
viability of Internet advertising.

    TO THE EXTENT THAT MINIMUM GUARANTEED IMPRESSION LEVELS ARE NOT MET OVER THE
CONTRACT PERIOD, WE DEFER RECOGNITION OF THE CORRESPONDING PRO RATA PORTION OF
THE REVENUES RELATED TO SUCH UNFULFILLED OBLIGATION UNTIL THE GUARANTEED
IMPRESSION LEVELS ARE ACHIEVED. Advertising based on impressions, or the number
of times an advertisement is delivered to users, represents substantially all of
our current revenues. To the extent that minimum impression levels are not
achieved for any reason, we may be required to provide additional impressions
after the contract term, which would reduce our advertising inventory.

    OUR REVENUES COULD BE ADVERSELY AFFECTED IF WE ARE UNABLE TO ADAPT TO OTHER
INTERNET ADVERTISING PRICING MODELS IF THEY ARE ADOPTED. It is difficult to
predict which, if any, pricing models for Internet advertising will emerge as
industry standards. This makes it difficult to project our future advertising
rates and revenues.

WE MAY NOT BE ABLE TO ADAPT AS INTERNET TECHNOLOGIES AND CUSTOMER DEMANDS
  CONTINUE TO EVOLVE.

    To be successful, we must adapt to rapidly changing Internet technologies by
continually enhancing ABOUT.COM and introducing new services to address our
users' changing demands. We could incur substantial costs if we need to modify
our services or infrastructure in order to adapt to changes affecting providers
of Internet services. Our business, results of operations and financial
condition could be materially adversely affected if we incurred significant
costs to adapt, or cannot adapt, to these changes.

THE DEVELOPMENT OF OUR BRAND IS ESSENTIAL TO OUR FUTURE SUCCESS.

    If our brand marketing efforts are unsuccessful, our business, financial
condition and results of operations would be materially adversely affected. In
order to build our brand awareness, we must succeed in our brand marketing
efforts, provide high-quality services and increase user traffic on ABOUT.COM.
These efforts have required, and will continue to require, significant expenses.

WE MAY NOT BE ABLE TO COMPETE SUCCESSFULLY.

    Competition could result in less user traffic to ABOUT.COM, price reductions
for our advertising inventory, reduced margins or loss of market share, any of
which would have a material adverse effect on our business, results of
operations and financial condition. We face intense competition for users and
for advertisers. We expect this competition to increase because there are no
substantial barriers to entry in our market. Competition may also increase as a
result of industry consolidation. We may not be able to compete successfully.

    We compete for users and advertisers with the following:

    - Internet "portal" companies, including Excite, Lycos and Yahoo!;

    - Internet retrieval and directories companies, including AskJeeves and
      LookSmart;

    - online content web sites, including C--net, ESPN.com and ZDNet.com;

    - online community web sites, including iVillage;

                                       6
<PAGE>
    - online personal homepage services, including GeoCities and theglobe.com;

    - publishers and distributors of television, radio and print, including CBS,
      Disney, NBC and Time Warner;

    - general purpose consumer online services, including America Online and
      Microsoft Network; and

    - web sites maintained by Internet service providers, including AT&T
      Worldnet, Earthlink and MindSpring.

    Our ability to compete depends on many factors, many of which are outside of
our control. These factors include the quality of content provided by us and by
our competitors, the ease of use of services developed either by us or by our
competitors, the timing and market acceptance of new and enhanced services
developed either by us or by our competitors, and sales and marketing efforts by
us and our competitors.

    We believe that many of our existing competitors, as well as potential new
competitors, have longer operating histories, greater name recognition, larger
customer bases and significantly greater financial, technical and marketing
resources than we do. This may allow them to devote greater resources than we
can to the development and promotion of their services. These competitors may
also engage in more extensive research and development, adopt more aggressive
pricing policies and make more attractive offers to existing and potential
employees, guides, distribution partners and advertisers. Our competitors may
develop services that are equal or superior to ABOUT.COM or that achieve greater
market acceptance than ABOUT.COM. In addition, current and potential competitors
have established or may establish cooperative relationships among themselves or
with third parties to increase the ability of their services to address the
needs of advertisers and electronic commerce marketers. As a result, it is
possible that new competitors may emerge and rapidly acquire significant market
share.

WE DEPEND ON RELATIONSHIPS WITH THIRD PARTIES.

    Our business, results of operations and financial condition could be
materially adversely affected if we do not establish and maintain distribution
relationships on commercially reasonable terms or if any of our distribution
relationships do not result in increased user traffic on ABOUT.COM. A portion of
the users who come to ABOUT.COM come from third-party web sites with which we
have non-exclusive, short-term distribution relationships. Since these web sites
may not attract significant numbers of users themselves, ABOUT.COM may not
receive a significant number of additional users from these relationships.
Moreover, we may have to pay significant fees to establish additional
relationships or maintain existing relationships in the future.

    We have entered into, and may continue to enter into, agreements with
advertisers or other third-party web sites that require us to exclusively
feature these parties for certain aspects of ABOUT.COM. These exclusivity
agreements may limit our ability to enter into other advertising or sponsorship
agreements or other strategic relationships. Many companies we may pursue for
strategic relationships also offer competing services. As a result, these
competitors may be reluctant to enter into strategic relationships with us.

WE MAY NOT EFFECTIVELY MANAGE OUR GROWTH.

    In order to execute our business plan, we must grow significantly. This
growth will place a significant strain on our personnel, management systems and
resources. If we do not manage growth effectively, our business, results of
operations and financial condition would be materially adversely affected. We
expect that the number of our employees, including management-level employees,
will continue to increase for the foreseeable future. In addition, we expect
that the number of guides will continue to increase as new topic-specific sites
are established. We must continue to improve our

                                       7
<PAGE>
operational and financial systems and managerial controls and procedures, and we
will need to continue to expand, train and manage our workforce. We must also
maintain close coordination among our technical, accounting, finance, marketing,
sales and editorial organizations.

REGULATORY AND LEGAL UNCERTAINTIES COULD HARM OUR BUSINESS.

    Any new law or regulation pertaining to the Internet, or the application or
interpretation of existing laws, could decrease the demand for our network,
increase our cost of doing business or otherwise have a material adverse effect
on our business, results of operations and financial condition. There are, and
will be, an increasing number of laws and regulations pertaining to the
Internet. These laws or regulations may relate to liability for information
retrieved from or transmitted over the Internet, online content regulation, user
privacy, taxation and the quality of products and services. Moreover, the
applicability to the Internet of existing laws governing intellectual property
ownership and infringement, copyright, trademark, trade secret, obscenity,
libel, employment, personal privacy and other issues is uncertain and
developing. Please see "Business--Government Regulation and Legal
Uncertainties."

WE MAY BE LIABLE FOR THE CONTENT WE MAKE AVAILABLE ON THE INTERNET.

    We make content available on ABOUT.COM and on the web sites of our
advertisers and distribution and syndication partners. The availability of this
content could result in claims against us based on a variety of theories,
including defamation, obscenity, negligence, copyright or trademark
infringement. Other claims may be brought based on the nature, publication and
distribution of our content or based on errors or false or misleading
information provided on ABOUT.COM, including information deemed to constitute
professional advice such as legal, medical, financial or investment advice. We
could also be exposed to liability for third-party content accessed through
ABOUT.COM'S links to other websites or posted by users in chat rooms or bulletin
boards offered on our topic-specific sites. Our financial condition could be
materially adversely affected if we were found liable for information that we
make available. Implementing measures to reduce our exposure to this liability
may require us to spend substantial resources and limit the attractiveness of
our services to customers. Please see "Business-- Government Regulations and
Legal Uncertainties."

IF WE ARE UNABLE TO SUCCESSFULLY INTEGRATE FUTURE ACQUISITIONS INTO OUR
OPERATION, THERE COULD BE AN ADVERSE EFFECT ON OUR BUSINESS AND RESULTS OF
OPERATIONS.

    We may acquire complementary businesses, products and technologies in the
future. Some of the risks attendant to these acquisitions are:

    - difficulties and expenses of integrating the operations and personnel of
      acquired companies into our operations while preserving the goodwill of
      the acquired entity;

    - the additional financial resources that may be needed to fund the
      operations of acquired companies;

    - the potential disruption of our business;

    - our management's ability to maximize our financial and strategic position
      by incorporating acquired technology or businesses;

    - the difficulty of maintaining uniform standards, controls, procedures and
      policies;

    - the potential loss of key employees of acquired companies;

    - the impairment of relationships with employees and customers as a result
      of changes in management; and

    - increasing competition with other entities for desirable acquisition
      targets.

                                       8
<PAGE>
    Any of the above risks could prevent us from realizing significant benefits
from our acquisitions. In addition, the issuance of our common stock in
acquisitions will dilute our stockholder interests, while the use of cash will
deplete our cash reserves. Finally, if we are unable to account for our
acquisitions under the "pooling of interests" method of accounting, we may incur
significant, one-time write-offs and amortization charges. These write-offs and
charges could decrease our future earnings or increase our future losses.

WE WOULD BE UNABLE TO PROVIDE CONTENT WITHOUT THE EFFORTS OF OUR NETWORK OF
  GUIDES.

    Our business, results of operations and financial condition would be
materially adversely affected if our guides fail to provide us with adequate
content or if we fail to successfully replace former guides on a timely basis.
We are substantially dependent on our network of guides for providing in-depth,
high-quality, up-to-date content that covers thousands of subjects. Our guides
may not continue to provide us with a sufficient amount of high-quality content
covering a broad enough range of subjects. Furthermore, any number of guides may
discontinue their relationship with us. In addition, since the guides are
independent contractors, we have less control over the content production
process than if the guides were our employees.

WE COULD INCUR SIGNIFICANT WITHHOLDING TAXES AND EMPLOYEE BENEFITS EXPENSES IF
  THE GUIDES WERE DEEMED TO BE OUR EMPLOYEES RATHER THAN INDEPENDENT
  CONTRACTORS.

    One or more jurisdictions or taxing authorities, including the Internal
Revenue Service, may seek to treat the guides as our employees rather than
independent contractors. As a result, they may seek to impose taxes, interest or
penalties on us. In addition, employees are generally entitled to healthcare and
other benefits that are typically unavailable to independent contractors. Since
we believe that the guides are independent contractors, we would vigorously
oppose any claim to the contrary. However, our efforts to do so might not be
successful. We are not able to estimate accurately the quantitative effect that
these taxes or employee benefit costs would have on us if the guides were deemed
to be employees. Our business, results of operations and financial condition
would be materially adversely affected if these claims are made and we do not
prevail or if we are required to treat the guides as employees for tax or
employee benefit purposes or otherwise. Please see "Business--Government
Regulation and Legal Uncertainties."

WE DEPEND ON OUR KEY EXECUTIVES AND WILL NEED ADDITIONAL PERSONNEL TO GROW OUR
  BUSINESS.

    Our future success depends, in part, on the continued service of our key
management personnel, particularly Mr. Scott P. Kurnit, our President and Chief
Executive Officer, and Mr. William C. Day, our Chief Operating Officer. Although
we are the beneficiary of a key person life insurance policy on Mr. Kurnit's
life, the loss of his services, or the services of other key employees, would
have a material adverse effect on our business, results of operations and
financial condition. Our future success also depends on our ability to attract,
retain and motivate highly skilled employees, including advertising sales
personnel. Competition for employees in our industry is intense. We may be
unable to attract, assimilate or retain other highly qualified employees in the
future. We have from time to time in the past experienced, and we expect to
continue to experience in the future, difficulty in hiring and retaining highly
skilled employees with appropriate qualifications.

THE PERFORMANCE OF ABOUT.COM IS CRITICAL TO OUR BUSINESS AND TO OUR REPUTATION.

    Any system failure, including network, software or hardware failure, that
causes an interruption in our network or a decrease in responsiveness of
ABOUT.COM could result in reduced user traffic on ABOUT.COM and reduced revenue.
ABOUT.COM has in the past experienced slower response times and interruptions in
service for a variety of reasons. ABOUT.COM could also be affected by computer
viruses, electronic break-ins or other similar disruptions. Our insurance
policies have low coverage limits and

                                       9
<PAGE>
therefore our insurance may not adequately compensate us for any losses that may
occur due to any interruptions to our network.

    In January 1998, we entered into an Internet-hosting agreement with Global
Center, Inc. to maintain all of our production servers at Global Center's
Manhattan Data Center. This agreement was extended in January 1999 and is
terminable by either party upon 90 days' notice. Our operations depend on Global
Center's ability to protect its and our systems against damage from fire, power
loss, water damage, telecommunications failures, vandalism and other malicious
acts, and similar unexpected adverse events. Any disruption in the Internet
access provided by Global Center could have a material adverse effect on our
business, results of operations and financial condition.

    Our users and our guides depend on Internet service providers, online
service providers and other web site operators for access to ABOUT.COM. Each of
these providers has experienced significant outages in the past, and could
experience outages, delays and other difficulties due to system failures
unrelated to our systems.

WE MAY BE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY AND WE MAY BE LIABLE FOR
  INFRINGING THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS.

    Third parties may infringe or misappropriate our patents, trademarks or
other intellectual property, which could have a material adverse effect on our
business, results of operations or financial condition. While we enter into
confidentiality agreements with our material employees, guides, consultants and
strategic partners, and generally control access to and distribution of our
proprietary information, the steps we have taken to protect our intellectual
property may not prevent misappropriation. In addition, we do not know whether
we will be able to defend our proprietary rights since the validity,
enforceability and scope of protection of proprietary rights in Internet-related
industries is uncertain and still evolving.

    Third parties may assert infringement claims against us. From time to time
in the ordinary course of business we have been, and we expect to continue to
be, subject to claims of alleged infringement of the trademarks and other
intellectual property rights of third parties. These claims and any resultant
litigation, should it occur, could subject us to significant liability for
damages. In addition, even if we prevail, litigation could be time-consuming and
expensive to defend, and could result in the diversion of our time and
attention. Any claims from third parties may also result in limitations on our
ability to use the intellectual property subject to these claims unless we are
able to enter into agreements with the third parties making these claims.

SEASONAL FACTORS MAY AFFECT OUR QUARTERLY OPERATING RESULTS.

    Seasonality of user traffic on ABOUT.COM and our advertising revenues may
cause our total revenues to fluctuate. User traffic on web sites has typically
declined during the summer and year-end vacation and holiday periods. We believe
that advertising sales in traditional media, such as television and radio,
generally are lower in the first and third calendar quarters of each year.
Similar seasonal or other patterns may develop in our business.

WE WOULD LOSE REVENUES AND INCUR SIGNIFICANT COSTS IF OUR SYSTEMS OR MATERIAL
  THIRD-PARTY SYSTEMS ARE NOT YEAR 2000 COMPLIANT.

    The failure of our internal systems, or any material third-party systems, to
be Year 2000 compliant would have a material adverse effect on our business,
results of operations and financial condition. Although we have received
compliance information from our material third-party vendors, we have not
received compliance information from all of our third-party vendors. It is also
possible that our third-party vendors were mistaken in certifying that their
systems are Year 2000 compliant. As a result, we cannot be sure that our
internal system, as a whole, is Year 2000 compliant. In addition, there can be

                                       10
<PAGE>
no assurance that governmental agencies, utility companies, Internet access
companies, third-party service providers and others outside of our control will
be Year 2000 compliant. The failure by those entities to be Year 2000 compliant
could result in a systemic failure beyond our control, as a prolonged Internet,
telecommunications or electrical failure, which could also prevent us from
delivering ABOUT.COM, decrease the use of the Internet or prevent customers from
accessing ABOUT.COM, any of which could have a material adverse effect on our
business, results of operations and financial condition. Based on the results of
our Year 2000 assessment, we have determined that it is not necessary to develop
a Year 2000 contingency plan. Please see "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Impact of the Year 2000."

WE CANNOT PREDICT OUR FUTURE CAPITAL NEEDS AND WE MAY NOT BE ABLE TO SECURE
  ADDITIONAL FINANCING.

    We may need to raise additional funds in the future in order to fund more
aggressive brand promotion or more rapid expansion, to develop new or enhanced
services, to respond to competitive pressures or to make acquisitions. Any
required additional financing may not be available on terms favorable to us, or
at all. If adequate funds are not available on acceptable terms, we may be
unable to fund our expansion, successfully promote our brand, or take advantage
of acquisition opportunities, develop or enhance services, respond to
competitive pressures or take advantage of acquisition opportunities, any of
which could have a material adverse effect on our business, results of
operations and financial condition. If additional funds are raised by our
issuing equity securities, stockholders may experience dilution of their
ownership interest and the newly issued securities may have rights superior to
those of the common stock. If additional funds are raised by our issuing debt,
we may be subject to limitations on our operations, including limitations on the
payment of dividends. We currently anticipate that our net proceeds from this
offering, together with currently available funds, will be sufficient to meet
our anticipated needs through at least 2000. Please see "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."

FUTURE SALES OF COMMON STOCK BY OUR EXISTING STOCKHOLDERS COULD ADVERSELY AFFECT
  OUR STOCK PRICE.

    Sales of a substantial number of shares of our common stock in the public
market could cause the market price of our common stock to decline and could
impair our ability to raise additional capital through the sale of equity
securities.

    As of September 30, 1999, we had approximately 12,288,418 shares of common
stock outstanding, of which approximately       shares were freely transferable
without restriction or registration under the Securities Act. After this
offering, 3,500,000 additional shares will be freely transferable, or
approximately 4,025,000 shares if the underwriters exercise their over-allotment
option in full. The remaining       shares of common stock held by existing
stockholders as of September 30, 1999 are "restricted securities" as that term
is defined in Rule 144 under the Securities Act. Approximately       shares of
our common stock are subject to "lock-up" agreements that generally prohibit the
sale or other transfer of the shares for 90 days from the date of this
prospectus without the prior written consent of Donaldson, Lufkin & Jenrette
Securities Corporation, the lead manager of this offering. From time to time,
these shares will become eligible for sale, subject in most cases to the volume,
holding period and other limitations of Rule 144 and Rule 701. After this
offering, approximately       restricted securities held by non-affiliates will
be eligible for sale from time to time under Rule 144(k) without volume and
manner of sale restrictions. In addition, we have filed a registration statement
on Form S-8 with the Securities and Exchange Commission covering 3,349,885
shares of common stock reserved for issuance under our stock plans as of
September 30, 1999. Sales of a large number of of any of these shares could have
an adverse effect on the market price for our common stock.

                                       11
<PAGE>
AFTER THIS OFFERING, OUR OFFICERS AND DIRECTORS MAY STILL CONTROL US.

    Our executive officers and directors will, in the aggregate, beneficially
own approximately     % of the common stock following this offering. These
stockholders may be able to exercise control over all matters requiring approval
by our stockholders, including the election of directors and approval of
significant corporate transactions. This concentration of ownership may also
have the effect of delaying or preventing a change in control of us, which could
have a material adverse effect on our stock price. Please see "Principal and
Selling Stockholders."

OUR STOCK PRICE HAS BEEN AND MAY CONTINUE TO BE VOLATILE.

    The market price of our common stock has fluctuated in the past and is
likely to continue to be highly volatile and could be subject to wide
fluctuations. In addition, the Nasdaq National Market, where most publicly held
Internet companies are traded, has experienced extreme price and volume
fluctuations. These fluctuations often have been unrelated or disproportionate
to the operating performance of these companies. These broad market and industry
factors may materially adversely affect the market price of our common stock,
regardless of our actual operating performance. In the past, following periods
of volatility in the market price of a company's securities, securities class
action litigation often has been instituted against that company. Litigation
like this, if instituted, could result in substantial costs and a diversion of
management's attention and resources.

YOU WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION.

    The public offering price per share will significantly exceed the net
tangible book value per share. Accordingly, investors purchasing shares in this
offering will suffer immediate and substantial dilution of their investment.
Please see "Dilution."

                    FORWARD-LOOKING STATEMENTS; MARKET DATA

    Many statements made in this prospectus under the captions "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere are
forward-looking statements that are not based on historical facts. Because these
forward-looking statements involve risks and uncertainties, there are important
factors that could cause actual results to differ materially from those
expressed or implied by these forward-looking statements, including those
discussed under "Risk Factors."

    This prospectus includes market data about us and the Internet industry.
These data come from information published by Media Metrix, Inc., a media
research firm specializing in market and technology measurement on the Internet,
and International Data Corporation, also known as IDC, and Forrester Research,
both of which are providers of market and strategic information for the
information technology industry. These market data include projections that are
based on a number of assumptions. The assumptions include that:

    - no catastrophic failure of the Internet will occur;

    - the number of people online and the total number of hours spent online
      will increase significantly over the next five years;

    - the value of online advertising dollars spent per online user hour will
      increase;

    - the download speed of content will increase dramatically; and

    - Internet security and privacy concerns will be adequately addressed.

    This type of data is inherently imprecise and investors should not place
undue reliance on these data. If any one or more of the foregoing assumptions
turns out to be incorrect, actual results may differ from the projections based
on these assumptions. The failure of these markets to grow at these projected
rates may have a material adverse effect on our business, results of operations
and financial condition, as well as the market price of our common stock.

                                USE OF PROCEEDS

    We estimate that the net proceeds we will receive from the sale of the
3,000,000 shares of common stock offered by us, after deducting estimated
underwriting fees and estimated offering expenses payable by us, will be
approximately $168.9 million (up to $198.6 million if the underwriters'
over-allotment option is exercised in full), at an assumed offering price of
$59.875 per share. We will not receive any proceeds from the sale of shares by
existing stockholders.

    We intend to use the net proceeds of this offering to execute our business
plan and for general corporate purposes. As part of this plan, we intend to
enhance the value of our brand, to expand our advertising sales efforts and to
further develop our network. We may also explore acquisitions or minority
investments.

    While we may also use a portion of our proceeds for acquisitions of
businesses, technologies and product offerings or minority investments in
businesses, we have no present commitments or agreements relating to any
acquisitions or investments. The amounts we actually spend for any of the
foregoing purposes may vary significantly and will depend on a number of
factors, including our future revenue, cash generated by operations, if any, and
other factors described under "Risk Factors." Accordingly, management will have
significant flexibility in applying our net proceeds. Pending any such use, as
described above, we intend to invest the net proceeds in interest-bearing
investment grade instruments. See "Risk Factors--If we are unable to
successfully integrate future acquisitions into our operations, there could be
an adverse effect on our business and results of operations."

    We have not declared or paid any cash dividends on our capital stock since
inception and do not expect to pay any cash dividends for the foreseeable
future. We currently intend to retain future earnings, if any, to finance the
expansion of our business.

    We expect that there will be approximately 15,288,418 shares of common stock

                                    DILUTION

    Our net tangible book value as of June 30, 1999 was $59,536,400, or $4.90
per share. Our net tangible book value per share is equal to the amount of our
total assets less intangible assets and less total liabilities, divided by the
number of shares of common stock outstanding as of June 30, 1999.

    Assuming that we sell the 3,000,000 shares offered by us at a public
offering price of $59.88 per share, after deducting estimated underwriting fees
and estimated offering expenses payable by us, our net tangible book value as of
June 30, 1999 would have been $228,450,000, or $15.09 per share. This represents
an immediate increase in net tangible book value of $10.19 per share to existing
stockholders and an immediate dilution in net tangible book value of $44.79 per
share to investors purchasing shares in this offering. The following table
illustrates this per share dilution:

Operations" included elsewhere in this prospectus. These statements of
operations data for the period from June 27, 1996 (inception) through December
31, 1996 and for the years ended December 31, 1997 and 1998, and the balance
sheet data at December 31, 1997 and 1998 are derived from our audited
consolidated financial statements included elsewhere in this prospectus. The
balance sheets data as of December 31, 1996 have been derived from our audited
consolidated financial statements not included in this prospectus. Historical
results are not necessarily indicative of the results to be expected in the
future.

    The selected consolidated financial data as of June 30, 1999 and for each of
the six months ended June 30, 1998 and 1999 are derived from our unaudited
interim consolidated financial statements included elsewhere in this prospectus.
The unaudited consolidated financial statements have been prepared on
substantially the same basis as the audited financial statements and include all
adjustments, consisting only of normal recurring adjustments, that we consider
necessary for a fair presentation of our financial position and results of
operations for those periods. Operating results for the six months ended June
30, 1999 are not necessarily indicative of the results that may be expected for
the year ending December 31, 1999.

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

    THE FOLLOWING DISCUSSION OF OUR FINANCIAL CONDITION AND RESULTS OF
OPERATIONS SHOULD BE READ TOGETHER WITH OUR CONSOLIDATED FINANCIAL STATEMENTS
AND THE NOTES TO THOSE STATEMENTS INCLUDED ELSEWHERE IN THIS PROSPECTUS. THIS
DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. PLEASE SEE "RISK FACTORS" AND "FORWARD-LOOKING STATEMENTS; MARKET
DATA."

OVERVIEW

    For the period from our incorporation on June 27, 1996 through April 1997,
our operating activities related primarily to the initial development of
ABOUT.COM, recruitment of employees and guides, and the establishment of our
organizational and technical infrastructure. Since the launch of our network in
April 1997, revenues and operating expenses have increased as we enhanced our
network of guides, expanded our editorial and operating staff, improved
ABOUT.COM's functions and features and promoted ABOUT.COM to increase brand
awareness. As part of our marketing efforts, we have conducted online campaigns
and, beginning in June 1998, an offline campaign consisting of a national trade
magazine print campaign, and outdoor and radio advertisements in selected
cities. In the second quarter of 1999, we conducted a significant offline
campaign consisting of a national print and television advertising campaign in
connection with the launch of the About.com brand.

    To date, we have derived substantially all of our revenues from the sale of
advertisements on ABOUT.COM. We expect to derive our revenues principally from
the sale of advertising on ABOUT.COM for the foreseeable future. We currently
offer advertisers numerous sizes and types of advertising placements, including
banner advertisements, button advertisements and text links. We also offer
sponsorship programs and other promotional opportunities to build brand
awareness and drive user traffic to an advertiser's web site. To date, sales of
advertisements on ABOUT.COM have been generated primarily by our internal
advertising sales organization.

    Advertisers on ABOUT.COM enter into agreements of typically between two
months and two years in duration. Pursuant to these agreements, we generally
guarantee a minimum number of impressions, or the number of times that an
advertisement is delivered to users of ABOUT.COM, to be delivered over a
specified period of time at a fixed rate. Revenues from advertising sales are
recognized ratably in the period in which the advertisement is displayed,
provided that we have no significant remaining obligations, at the lesser of the
ratio of impressions delivered over total guaranteed impressions or the straight
line basis over the term of the contract, and collection of the resulting
receivable is probable. Payments received from advertisers prior to displaying
their advertisements on ABOUT.COM are recorded as deferred revenues and are
recognized as revenues ratably as the advertisements are displayed. To the
extent these minimum guaranteed impression levels are not met ratably over the
contract period, we defer recognition of the corresponding pro rata portion of
the revenues related to such unfulfilled obligation until the guaranteed
impression levels are achieved. When there is no guarantee that we deliver a
minimum number of impressions over a specified period, we recognize revenue in
the period in which the impressions are delivered.

    Some agreements with advertisers entitle us to a share of revenues generated
by sales of merchandise and services over a particular threshold resulting from
direct links from ABOUT.COM. Through June 30, 1999, we had not recognized any
material revenues from these revenue sharing agreements. Any revenues we derive
from these revenue sharing agreements will be recognized upon notification from
our advertisers of sales attributable to ABOUT.COM.

    Our agreements with our channel partners are typically at least 12 months in
duration and generally require our partners to make payments to us for
development, placement and advertising payments. We recognize any development
fees as the services are provided. We recognize any placement fees ratably over
the term of the agreement.

                                       18
<PAGE>
    Approximately 10% of our revenues during the year ended December 31, 1998
and approximately 7% of our revenues for the six month period ended June 30,
1999 were generated by agreements where we traded advertisements on ABOUT.COM in
exchange for advertisements on third-party web sites without receiving any cash
payment. The corresponding expenses from these barter arrangements, which equal
the amount of the barter revenues from these arrangements, are included as a
component of cost of revenues. We anticipate that barter revenues will continue
to account for up to 10% of our total annual revenues.

    Guide compensation is generally included as a component of cost of revenues.
We currently compensate guides at an amount equal to the greater of a monthly
minimum guarantee or a percentage of net advertising revenues generated in the
ABOUT.COM network. This revenue is distributed among the guides based on the
user traffic on their respective topic-specific sites as a percentage of traffic
for the whole network. Guides are also currently entitled to share a percentage
of net transaction revenues and net syndication revenues.

    In connection with our initial public offering, we granted fully vested,
non-qualified stock options to purchase 199,500 shares of common stock to a
substantial majority of our guides. The exercise price per share of these
options was $25.00 and the options have two-year terms. Since the guides are
independent contractors, we recorded non-cash compensation expense of
approximately $3.6 million during the quarter ended March 31, 1999, representing
the fair market value of the options at the date of grant. This amount is
presented in a separate line item above the gross profit (loss) line.

    Through June 30, 1999, we had recorded deferred compensation expense of
approximately $4.5 million in connection with the grant of stock options to
employees and directors, representing the difference between the deemed value of
the common stock at the date of grant for accounting purposes and the exercise
price of the related options. We amortize this non-cash expense over the vesting
period, typically four years, of the applicable options. Amortization of
deferred compensation expense was $478,000 for the year ended December 31, 1998
and $625,000 for the six months ended June 30, 1999, of which $9,000 is related
to deferred compensation expense for the grant of options to operations
personnel and has been included in the non-cash compensation expense line item
appearing above the gross profit (loss) line. We currently expect to amortize
the following amounts of deferred compensation expense annually: 1999--$1.1
million; 2000--$1.0 million; 2001--$1.0 million; and 2002-- $0.9 million.

    In June 1999, we acquired VantageNet, Inc. In connection with this
acquisition, we recorded goodwill and purchased intangibles of $2.5 million. We
are amortizing the goodwill and purchased intangibles related to this
acquisition over the expected period of benefit of 3 years.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998

    REVENUES.  Revenues consist primarily of advertising revenues on ABOUT.COM.
For the six months ended June 30, 1999, revenues increased to $6.1 million,
which included $452,000 of barter revenues, from $548,000, which included
$49,000 of barter revenues, for the six months ended June 30, 1998. This
period-to-period growth was primarily attributable to an increase in (1) the
number of advertisers and the average commitment per advertiser, (2) user
traffic on ABOUT.COM and (3) the number of our sales people. We anticipate that
revenues from advertising will continue to account for substantially all of our
revenues for the foreseeable future.

    COST OF REVENUES.  Since the launch of ABOUT.COM in April 1997, cost of
revenues has consisted primarily of guide compensation, third-party Internet
advertising sales organization fees, salaries of operating personnel, site
hosting and depreciation costs, barter advertising expenses and other product
costs. Cost of revenues increased to $5.2 million for the six months ended June
30, 1999 from

                                       19
<PAGE>
$1.3 million for the six months ended June 30, 1998. The increase in cost of
revenues was due to an increase in site hosting costs to support the increase in
web site traffic, as well as an increase in depreciation and staff costs
required to support the expansion of ABOUT.COM.

    NON-CASH COMPENSATION EXPENSE.  For the six months ended June 30, 1999 and
1998, non-cash compensation expense increased to $3.6 million from $20,000.
Non-cash compensation expense included amortization of deferred compensation
relating to the grant of options to operations personnel in the amounts of
$9,000 for the six months ended June 30, 1999 and $20,000 for the six months
ended June 30, 1998. Non-cash compensation expense for the six months ended June
30, 1999 also included a charge in the amount of $3.6 million relating to our
grant of stock options to the guides upon the closing of our initial public
offering.

    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
online and offline advertising costs, salaries and commissions of internal sales
and marketing personnel, public relations costs, payments to third-party
Internet companies to drive user traffic to ABOUT.COM and other marketing
related expenses. For the six months ended June 30, 1999 and 1998, sales and
marketing expenses increased to $23.8 million from $1.4 million. This
period-to-period increase was primarily attributable to the non-recurring
expenditures related to the launch of the About.com brand in the second quarter
as well as an increase in our general sales and marketing expenses.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of salaries and related costs for general corporate functions,
including finance, accounting, facilities and professional services. For the six
months ended June 30, 1999 and 1998, general and administrative expenses
increased to $3.3 million from $1.1 million. The increase in general and
administrative expenses was primarily attributable to increased salaries and
related expenses associated with hiring additional personnel, facility-related
expenses, and costs relating to our operation as a public company. We expect
that we will incur additional general and administrative expenses as we hire
additional personnel and incur additional costs related to the growth of our
business and our operation as a public company, including directors' and
officers' liability insurance, investor relations programs and professional
services fees.

    PRODUCT DEVELOPMENT.  Product development expenses include personnel and
consulting costs associated with the design, development and testing of
ABOUT.COM and our systems and editorial personnel costs. We expense our product
development costs as incurred. For the six months ended June 30, 1999 and 1998,
product development expenses increased to $2.9 million from $1.2 million. This
period-to-period increase was primarily attributable to increased staffing
levels to support our growth and development. We believe that timely deployment
of new and enhanced features and technology are critical to attaining our
strategic objectives. Accordingly, we intend to continue recruiting and hiring
experienced product development personnel and to make additional investments in
product development.

    NON-CASH COMPENSATION EXPENSE.  For the six months ended June 30, 1999 and
1998, amortization of deferred compensation expense relating to the grant of
options to non-operations personnel amounted to $616,000 and $231,000,
respectively.

    GOODWILL.  Goodwill amortization related to the acquisition of VantageNet
amounted to $33,000 for the six months ended June 30, 1999.

    OTHER INCOME (EXPENSE), NET.  Other income (expense), net includes interest
expense related to our debt and capital lease obligations, net of interest
income from our cash and cash equivalents. For the six months ended June 30,
1999 and 1998, other income (expense), net increased to $818,000 from
$(571,000). The increase in other income was primarily attributable to the
interest income generated by the increase in cash and cash equivalents from our
initial public offering.

                                       20
<PAGE>
    CUMULATIVE DIVIDENDS AND ACCRETION OF CONVERTIBLE PREFERRED
STOCK.  Cumulative dividends and accretion on our convertible preferred stock
amounted to $659,000 during the six months ended June 30, 1999. Each share of
convertible preferred stock was entitled to a cumulative dividend at a rate of
$0.135 per share per annum for the Series A convertible preferred stock, $0.162
per share per annum for the Series B convertible preferred stock and $0.176 per
share per annum for the Series C convertible preferred stock. Upon the closing
of our initial public offering, 3,346,715 shares of Series A convertible
preferred stock, 6,597,596 shares of Series B convertible preferred stock and
7,301,811 shares of Series C convertible preferred stock, representing all of
our outstanding shares of convertible preferred stock, automatically converted
into 6,139,640 shares of common stock.

PERIOD FROM JUNE 27, 1996 (INCEPTION) TO DECEMBER 31, 1996 COMPARED TO YEAR
  ENDED DECEMBER 31, 1997, COMPARED TO YEAR ENDED DECEMBER 31, 1998

    REVENUES.  We launched our web service in April 1997. Revenues were $0 for
the period from June 27, 1996 (inception) to December 31, 1996, $391,000 for the
year ended December 31, 1997, which included $73,000 of barter revenues, and
$3.7 million for the year ended December 31, 1998, which included $366,000 of
barter revenues. This growth was primarily attributable to an increase in (1)
the number of advertisers and the average commitment per advertiser, (2) user
traffic on ABOUT.COM and (3) the number of our sales people. During the year
ended December 31, 1998, we derived 12%, or $450,000, of our revenues from an
advertising arrangement with Citibank, which ended on December 31, 1998.

    COST OF REVENUES.  In 1996, our first year of operation, cost of revenues
consisted of guide compensation, site hosting and depreciation costs incurred in
connection with developing our service. Cost of revenues was $91,000 for the
period from June 27, 1996 (inception) to December 31, 1996, $1.9 million for the
year ended December 31, 1997 and $4.2 million for the year ended December 31,
1998. This period-to-period growth in cost of revenues was primarily
attributable to an increase in the fees paid to guides, which increased by $1.1
million from 1996 to 1997 and an additional $1.0 million from 1997 to 1998, and
in site hosting and operations costs, which increased by $492,000 from 1996 to
1997 and an additional $570,000 from 1997 to 1998, which was due to growth in
user traffic on ABOUT.COM. Commencing in June 1998, we engaged a third-party
Internet advertising sales representative organization to supplement our
internal advertising sales force in selling our advertising inventory in
exchange for a service fee. Fees paid to the third-party Internet advertising
sales organization accounted for an increase of $233,000 in cost of revenues
from 1997 to 1998.

    NON-CASH COMPENSATION EXPENSE.  There were no non-cash compensation expenses
for the period from June 27, 1996 (inception) to December 31, 1996 or for the
year ended December 31, 1997. For the year ended December 31, 1998, amortization
of deferred compensation expense relating to stock options granted to operations
personnel was $27,000.

    SALES AND MARKETING.  Sales and marketing expenses were $241,000 for the
period from June 27, 1996 (inception) to December 31, 1996, $1.8 million for the
year ended December 31, 1997, and $7.9 million for the year ended December 31,
1998. In 1996, we did not dedicate meaningful funds to sales and marketing as
ABOUT.COM was not launched until April 1997. The increase in sales and marketing
expenses from 1996 to 1997 was primarily attributable to the initiation of our
online advertising and other promotional expenditures, which increased by
$916,000, as well as increased sales and marketing personnel and related
expenses, which increased by $512,000. The increase in sales and marketing
expenses from 1997 to 1998 was primarily attributable to the initiation of our
offline marketing and the expansion of online advertising efforts, which
accounted for an increase of $4.9 million, of which $817,000 was expense related
to third-party Internet companies to drive user traffic to ABOUT.COM, as well as
increased sales and marketing personnel and related expenses, which increased by
$329,000.

                                       21
<PAGE>
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses were $1.1
million for the period from June 27, 1996 (inception) to December 31, 1996, $2.0
million for the year ended December 31, 1997, and $2.9 million for the year
ended December 31, 1998. The increase in general and administrative expenses was
primarily attributable to increased salaries and related expenses associated
with hiring additional personnel and facility-related expenses. The absolute
dollar increase in general and administrative expenses was primarily
attributable to increased salaries and related expenses associated with hiring
additional personnel, which increased by $694,000 from 1996 to 1997 and by
$622,000 from 1997 to 1998, and facility-related expenses, which increased by
$588,000 from 1996 to 1997 and by $622,000 from 1997 to 1998, to support the
growth in our operations.

    PRODUCT DEVELOPMENT.  Product development expenses were $948,000 for the
period from June 27, 1996 (inception) to December 31, 1996, $3.0 million for the
year ended December 31, 1997, and $3.1 million for the year ended December 31,
1998. We launched our site in April 1997. The increase in absolute dollars in
product development expenses from 1996 to 1997 was primarily attributable to
increased staffing levels required to design, develop and test modifications and
improvements to ABOUT.COM. Product development expenses remained relatively
constant from 1997 to 1998 due to nonrecurring consulting fees associated with
the pre-launch development of ABOUT.COM incurred during the first six months of
1997, offset by an increase in staffing levels in 1998 and 1999 to support the
growth and development of ABOUT.COM.

    NON-CASH COMPENSATION EXPENSE.  During 1998, amortization of deferred
compensation relating to stock options granted to non-operations personnel
amounted to $451,000.

    OTHER INCOME (EXPENSE), NET.  Other income (expense), net was $(57,000) for
the period from June 27, 1996 (inception) to December 31, 1996, $(299,000) for
the year ended December 31, 1997 and $(686,000) for the year ended December 31,
1998. The change was primarily attributable to interest accrued on outstanding
debt obligations and amortization of debt discount. During 1997, we provided
consulting services to Citibank for an aggregate amount of $450,000. Pursuant to
our agreement with Citibank, we agreed to provide strategic assistance in
creating, supporting and managing customized web sites around which communities
on specific areas of interest for the financial institution's customers would be
created. The term of the agreement was from June 20, 1997 through December 15,
1997. Fees generated by these services, net of expenses, were recorded as other
income, net, of which $350,000 was recorded for the year ended December 31,
1997. We did not provide consulting services during 1998 and do not anticipate
providing consulting services in the future.

    CUMULATIVE DIVIDENDS AND ACCRETION OF CONVERTIBLE PREFERRED
STOCK.  Cumulative dividends and accretion on our convertible preferred stock
amounted to $1.2 million in 1998.

    We have a limited operating history upon which to evaluate our business and
to predict revenues and plan operating expenses. In order to be successful, we
must attract more user traffic to ABOUT.COM and generate significant advertising
revenues. We expect our quarterly operating results to vary significantly in the
future due to a variety of factors, many of which are outside our control. Since
we expect to be substantially dependent on revenues from advertising for the
foreseeable future, our quarterly revenues are likely to be particularly
affected by user traffic levels on ABOUT.COM. We launched our service in April
1997 with a significant online marketing campaign. As a result, we spent
significant amounts on marketing in the second quarter of 1997 to help support
this launch. During the second half of 1997, our general and administrative
expenses declined due to reductions in compensation of our officers. Following
the completion of a private equity financing in April 1998, we used a portion of
the proceeds to begin our offline marketing campaign. During the second quarter
of 1999, we significantly increased our spending on marketing in connection with
the launch of our About.com brand. Please see "Risk Factors--Our quarterly
operating results may fluctuate."

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations primarily through the
private placement of equity securities, the incurrence of indebtedness and the
sale of common stock in our initial public offering. In March 1999, we received
net proceeds of approximately $81.0 million from our initial public offering and
a concurrent private placement of shares of our common stock.

    To date, we have experienced negative cash flows from operating activities.
Net cash used in operating activities was $6.0 million for the year ended
December 31, 1997 and $9.8 million for the year ended December 31, 1998. Net
cash used in operating activities was $4.3 million for the six months ended June
30, 1998 and $25.5 million for the six months ended June 30, 1999. Net cash used
in operating activities for these periods was primarily attributable to our net
losses during these periods, adjusted for certain non-cash items, and a higher
level of accounts receivable resulting from an increase in our revenues, which
was partially offset by increases in accounts payable and accrued expenses.

    Net cash used in investing activities was $148,000 for the year ended
December 31, 1997 and $2.9 million for the year ended December 31, 1998. Net
cash used in investing activities was $243,000 for the six months ended June 30,
1998 and $5.9 million for the six months ended June 30, 1999. Prior to 1999, all
net cash used in investing activities related to capital expenditures, primarily
for the acquisition of equipment. For the six months ended June 30, 1999, net
cash used in investing activities consisted primarily of $4.8 million of capital
expenditures, primarily for the acquisition of equipment,

                                       23
<PAGE>
$587,000 related to the acquisition of VantageNet and $488,000 related to the
purchase of certain intangible assets.

    Net cash provided by financing activities was $4.8 million for the year
ended December 31, 1997 and $23.1 million for the year ended December 31, 1998.
Net cash provided by financing activities was $8.8 million for the six months
ended June 30, 1998 and $82.3 million for the six months ended June 30, 1999.
Net cash provided by financing activities in 1997 was primarily attributable to
net proceeds received by us from the issuance of loans payable. Net cash
provided by financing activities in 1998 was primarily attributable to net
proceeds from the issuances of loans payable and preferred stock and the
exercise of warrants by investors in December 1998, and, to a lesser extent,
borrowings under a secured credit facility related to equipment financing. At
December 31, 1998, there was no additional
availability under this credit facility and the balance outstanding was
$438,000, of which $154,000 is due in 1999, $157,000 in 2000 and $126,500 in
2001. In January and February 1999, we entered into a lease line of credit for
$781,000 to finance capital equipment, of which $232,000 is due in 1999,
$269,000 in 2000, $273,000 in 2001 and $7,000 in 2002. Net cash provided by
financing activities for the six months ended June 30, 1999 consisted primarily
of approximately $81.0 million in net proceeds received by us in connection with
the closing of our initial public offering and concurrent placement in March
1999 and $619,000 of proceeds, net of repayments, from our secured credit
facility. Net cash provided by financing activities for the six months ended
June 30, 1998 consisted primarily of $8.7 million of net proceeds received by us
from the issuance of loans payable and preferred stock and, to a lesser extent,
proceeds from a secured credit facility related to equipment financing.

    As of June 30, 1999, we had $61.5 million of cash and cash equivalents. Our
principal capital commitments consisted of obligations outstanding under capital
and operating leases and a secured credit facility. We have spent approximately
$8.3 million on capital expenditures since inception, excluding capital lease
agreements. Although we have no material commitments for capital expenditures,
we anticipate that we will substantially increase our capital expenditures and
lease commitments consistent with our anticipated growth in operations,
infrastructure and personnel. We currently anticipate that we will continue to
experience significant growth in our operating expenses for the foreseeable
future and that our operating expenses will be a material use of our cash
resources.

    Our ability to generate significant revenues is uncertain. We have incurred
substantial costs to create, launch and enhance ABOUT.COM and to grow our
business. We incurred net losses of $2.4 million for the period from June 27,
1996 (inception) to December 31, 1996, $8.6 million for the year ended December
31, 1997, $15.6 million for the year ended December 31, 1998, $5.2 million for
the six months ended June 30, 1998 and $32.6 million for the six months ended
June 30, 1999. At June 30, 1999, we had an accumulated deficit of $59.3 million.
We expect losses from operations and negative cash flow to continue for the
foreseeable future as a result of our expansion plans and our continuing
significant increases in operating expenses in the next several years. Although
we have experienced revenue growth in recent periods, our revenues may not
remain at their current level or increase in the future. If our revenues do not
increase substantially, we may not achieve profitability. Even if we achieve
profitability, we may not sustain or increase profitability on a quarterly or
annual basis in the future.

    We currently anticipate that the net proceeds of this offering, together
with available funds, will be sufficient to meet our anticipated needs at least
through 2000. We may need to raise additional funds in the future in order to
fund more aggressive brand promotion or more rapid expansion, to develop new or
enhanced services, to respond to competitive pressures or to make acquisitions.
Any required additional financing may not be available on terms favorable to us,
or at all. If adequate funds are not available or not available on acceptable
terms, we may be unable to fund our expansion, successfully promote our brand,
develop or enhance our network, respond to competitive pressures or take
advantage of acquisition opportunities, which could have a material adverse
effect on our business, results of operations and financial condition. If we
raise additional funds by issuing equity securities, stockholders

                                       24
<PAGE>
may experience dilution of their ownership interest and those securities may
have rights superior to those of the holders of the common stock. If we raise
additional funds by issuing debt, we may be subject to certain limitations on
our operations, including limitations on the payment of dividends.

IMPACT OF THE YEAR 2000

    Many currently installed computer systems and software products are coded to
accept or recognize only two-digit entries in the date code field. These systems
may recognize a date using "00" as the year 1900 rather than the year 2000. As a
result, computer systems and/or software used by many companies and governmental
agencies may need to be upgraded to comply with Year 2000 requirements or risk
system failure or miscalculations causing disruptions of normal business
activities.

    We are exposed to the risk that the systems on which we depend to conduct
our operations are not Year 2000 compliant.

    STATE OF READINESS. We have completed the process of determining the Year
2000 readiness of our information technology systems, which include the hardware
and software necessary to provide and deliver ABOUT.COM and our non-information
technology systems, including telephone systems and other office equipment used
internally. Our assessment plan consisted of the following steps:

    - evaluating our date dependent code, software and hardware and evaluating
     external dependencies;

    - quality assurance testing of our internally-developed proprietary software
     and systems incorporated in ABOUT.COM;

    - contacting third-party vendors and licensors of material hardware,
     software and services; and

    - contacting vendors of material non-information technology systems used by
     us.

    To date, our assessment has determined the following:

    - Internally developed software and systems have been checked for date
     dependent code, and all material files and systems are Year 2000 compliant.

    - We have been informed by vendors of material hardware and software
     components of our information technology systems that the products we use
     are currently Year 2000 compliant.

    - Our hosting service, GlobalCenter, has certified that its systems are Year
     2000 compliant.

    - Commercial software upon which we are dependent is either Year 2000
     compliant or will be timely upgraded to be compliant in the normal course
     of business through upgrades or installation of software patches.

    - Substantially all hardware used in our network operations and all of the
     hardware used in our office operations has been certified as Year 2000
     compliant by our vendors.

    - Our telephone system, fax machines and mail systems have been certified as
     Year 2000 compliant.

    - Our landlords and third-party advertising sales representative and
     servicing organizations have not yet provided us with information regarding
     their Year 2000 compliance.

    COSTS.  We anticipate that no additional costs will be incurred for our year
2000 compliance efforts.

    RISKS.  Although we have received compliance information from our material
third-party vendors, we have not received compliance information from all of our
third-party vendors. In addition, it is possible that our third-party vendors
were untruthful or mistaken in certifying that their systems and

                                       25
<PAGE>
products are Year 2000 compliant. Being required to fix or replace material
third-party software, hardware or services on a timely basis could result in
lost revenues, increased operating costs, damage to our reputation, system
failures and other business interruptions, any of which could have a material
adverse effect on our business, results of operations and financial condition.

    In addition, governmental agencies, utility companies, Internet access
companies, third-party service providers and others outside our control may not
be Year 2000 compliant. The failure by those entities to be Year 2000 compliant
could result in a systemic failure beyond our control, such as a prolonged
Internet, telecommunications or electrical failure, which could also prevent us
from delivering ABOUT.COM, decrease the use of the Internet or prevent users
from accessing ABOUT.COM, any of which would have a material adverse effect on
our business, results of operations and financial condition.

    CONTINGENCY PLAN.  Based on the results of the Year 2000 assessment, we have
determined that it is not necessary to develop a contingency plan to address the
worst-case scenario that might occur if technologies we are dependent upon
actually are not Year 2000 compliant.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

    In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use," which provides guidance for determining
whether computer software is internal-use software and accounting for the
proceeds of computer software originally developed or obtained for internal use
and then subsequently sold to the public. Statement of Position 98-1 also
provides guidance on capitalization of the costs incurred for computer software
developed or obtained for internal use. We adopted Statement of Position 98-1 in
1999 and there has not been any material effect on the financial statements.

OVERVIEW

    We operate ABOUT.COM, a network of more than 650 highly-targeted,
topic-specific web sites. Our network is differentiated by the high quality and
depth of content we provide to users through the efforts of knowledgeable human
guides who manage the sites, the volume of sites in our network and the
consistency of site structure and design across the network. The sites provide
high-quality original articles, moderated forums and chat rooms, newsletters,
easy access to related sites, tools, and functionality within the ABOUT.COM
network and extensive hand-picked links to web sites outside of ABOUT.COM. We
pre-screen, train and monitor our guides to ensure quality and consistency
across our network.

    Our network has been the fastest growing property among the top 25 Internet
properties ranked by Media Metrix since we launched the About.com brand in May
1999. According to Media Metrix, approximately 8.9 million unique users visited
ABOUT.COM in August 1999, making ABOUT.COM the number one
news/information/entertainment Internet property in terms of audience reach and
the fifteenth largest Internet property overall.

    We believe that the design of our network provides an attractive advertising
and electronic commerce platform for reaching highly concentrated groups of
users. Because our network is organized into sections and channels of related
sites, we provide advertisers and electronic commerce marketers the ability to
access specific audiences through our highly targeted sites or use our sections,
channels or network to reach broader audiences.

INDUSTRY BACKGROUND

    GROWTH OF INTERNET USAGE

    The Internet is a significant global mass medium for conducting business,
collecting and exchanging information, communicating and entertaining.
International Data Corporation, or IDC, estimates that the number of Internet
users worldwide will grow from approximately 142.2 million at the end of 1998 to
approximately 502.4 million by the end of 2003, representing a compound annual
growth rate of 29%. As Internet usage continues to grow, advertisers and
electronic commerce marketers are increasingly using the web to locate
customers, advertise and facilitate transactions.

    ADVERTISING.  The Internet allows advertisers to more precisely target
desired audiences while tracking impression levels, user demographics and
advertisement effectiveness. According to Forrester Research, the total
worldwide dollar value of Internet advertising will increase from $3.3 billion
in 1999 to $24.1 billion in 2003.

    ELECTRONIC COMMERCE.  The Internet allows marketers to interact more
effectively with customers and to more easily obtain relevant data about buying
patterns, preferences and demands. According to IDC, the percentage of Internet
users buying goods and services on the Internet will increase from approximately
22% in 1998 to approximately 36% in 2003, and the total value of goods and
services purchased directly on the web will increase from approximately $27.0
billion in 1998 to approximately $842.7 billion in 2003.

    LOCATING INFORMATION ON THE INTERNET

    The proliferation of content is making it increasingly difficult and
time-consuming for users to navigate the Internet and to locate useful and
relevant information. According to IDC, the number of web pages will increase
from approximately 925 million at the end of 1998 to over 13 billion by the end
of 2003, representing a compound annual growth rate of 70%. A number of methods
and sources have emerged to enable Internet users to find information:

                                       27
<PAGE>
    INTERNET DIRECTORIES.  Internet directories generally list web sites by
specific topics of interest and contain links to these sites. With the rapid
growth of content available on the Internet, these directories are becoming
increasingly difficult to build and update with a high level of quality. In
addition, the creators of these directories often have limited relevant
knowledge about the directories' particular topic areas.

    INTERNET SEARCH ENGINES.  Internet search engines capture, store and index
web site information in order to retrieve web site listings in response to a
user query. These software programs have a limited ability to determine the
quality or relevance of the web sites they retrieve. Further, as the nature of
the available content has become more difficult to classify, many companies
offering search engines are being forced to employ significant editorial staffs
to ensure that responses to queries are satisfactory. Search engines based on
natural language have the added difficulty of accurately determining sentence
syntax and nuances.

    INTERNET PORTALS.  Many traditional Internet directories and search engines
have added commodity tools and features, such as weather, news feeds, stock
portfolios and personal home pages, and a limited amount of non-proprietary
content from other media. These portals provide Internet users with basic
information and static links on a broad range of topics. Because most portals
have many similar tools and features and provide limited original content, there
is little differentiation among them.

    TOPIC-SPECIFIC SITES.  More in-depth content is generally found on sites
focused on particular topics where individuals knowledgeable about those topics
create the content. Because these sites tend to be widely dispersed, Internet
users may need to visit a number of other, unaffiliated sites in order to
satisfy their information needs.

    USER-GENERATED CONTENT SITES.  Many web sites provide a forum for users to
generate and contribute relevant content. However, the quality of this content
varies significantly and the content is frequently unmanaged and poorly
organized and presented. As a result, advertisers may be reluctant to entrust
their brands to sites that rely upon user-generated content.

OUR SOLUTION

    We offer users a broad network of over 650 topic-specific sites in order to
help users locate information within and outside of our network. In doing so, we
create an environment in which advertisers can direct their messages to targeted
audiences ranging from all users of our network to the users of a specific site.

    HIGH-QUALITY, TOPIC-SPECIFIC SITES.  Each of our topic-specific sites is
overseen by a guide who is knowledgeable about the site's topic. Our experienced
editorial staff pre-screens, trains and oversees these guides in order to ensure
a quality user experience. As a result of this guide management process, our
sites incorporate high-quality original articles, information and relevant
hand-picked links to third-party web sites within and outside our network.

    NETWORK BENEFITS.  ABOUT.COM is designed to enable users to move rapidly and
efficiently throughout our networks and to find relevant information on a wide
range of topics. To facilitate user navigation, we group our web sites into
sections that are then incorporated into broad, topical channels. All of our
sites, sections and channels are designed and presented in a consistent manner
so that users moving through ABOUT.COM can easily find the information they are
seeking. By using standard templates and a patented guide-management
methodology, we can easily and cost-effectively add new sites to address new
topics of interest and to develop event-driven and seasonal web sites.

    ATTRACTIVE ADVERTISING AND ELECTRONIC COMMERCE PLATFORM.  We believe our
network offers a broad range of advertising and electronic commerce marketing
opportunities. By organizing related sites into channels and sections, we
provide advertisers and electronic commerce marketers with significant
flexibility to select the level of targeting that they want to achieve on
ABOUT.COM. Advertisers and

                                       28

electronic commerce marketers can access broad audiences by advertising across
our network or reach more targeted audiences by advertising in specific
channels, sections or web sites.

OUR STRATEGY

    Our objective is to enhance our position as the leading Internet network of
topic-specific web sites. The key elements of our strategy include:

    ENHANCING CHANNELS.  We believe that many of our topic-specific sites have
the opportunity to become market leaders in their given categories. Towards this
end, we will continue to internally develop the content and services offered at
the channel, section and site levels. In selected categories, we may choose to
partner with companies having tools or content that will enable us to expand the
information available in these categories and establish market leadership for
ABOUT.COM.

    INCREASING TRAFFIC.  We intend to increase user traffic to ABOUT.COM by
expanding the features available on our network and increasing cross-promotion
among our topic-specific sites. We believe these efforts will promote user
loyalty, increase repeat usage and extend duration per visit. In addition, we
have recently established an affiliate marketing program in which third parties
can incorporate features and tools from ABOUT.COM that enable their users to
link into our network to utilize those tools and access our content. We intend
to supplement these efforts to increase traffic by continuing to form selected
distribution and syndication partnerships.

    CONTINUING TO BUILD BRAND AWARENESS.  We believe that enhancing our brand
awareness is critical to attracting and retaining Internet users and
advertisers. In May 1999, we conducted a significant marketing campaign in
connection with the launch of ABOUT.COM. We intend to continue to build our
brand awareness through offline and online marketing efforts.

    MAXIMIZING REVENUES FROM HIGHLY-TARGETED ADVERTISING.  As traffic to our
network has increased, we have begun to emphasize premium-priced advertising
that provides our advertisers with highly-targeted audiences at the site level.
We have increased the number of sites on which we have sold site-specific
advertising from seven in March 1999 to 77 in June 1999. We believe we have
significant opportunities to sell premium-rate, targeted advertising on
additional sites, as well as across combinations of sites, sections and
channels.

CHANNEL STRUCTURE AND DEVELOPMENT

    Our network currently consists of more than 650 topic-specific sites, each
of which focuses on a particular topic and is overseen by a knowledgeable and
paid guide. For ease of use and for enhanced advertising opportunities, we have
grouped our more than 650 topic-specific sites into the following 18 channels,
which in turn are divided into the indicated sections:

    We will continue to enhance the content and services offered at the channel,
section and site levels. Towards this end, we have created a cross-discipline
team structure to focus on the needs of particular channels. In those areas
where we believe our internal offering can compete successfully on an
independent basis, the relevant channel teams will focus their energy on the
channel's further development. In other selected areas, we may choose to
strengthen our channel offering by combining the benefits of our network with
the tools or content of a third-party. These relationships can vary from
providing content for a particular area of a channel or section to sponsoring an
entire channel or section. They also enable us to increase the breadth of
content on our network without incurring significant development costs. These
third-party channel development agreements are typically at least 12 months in
duration and require our partners to make payments to us for development,
placement and advertising. To date, we have formed partnerships in the following
channels and sections:

    - AboutShopping with ShopNow.com;

    - AboutFinance with The Motley Fool;

    - AboutComputing/Technology with CMP Media, Inc.;

    - Auto Section with Cars.com; and

    - Careers Section with HotJobs.com.

    We have also entered into partnerships to enhance our service offerings
across several of our channels and sections. In the future, we may also expand
our channel and section offerings through the acquisition of complementary
businesses and technologies.

DISTRIBUTION AND SYNDICATION PARTNERSHIPS

    We believe that our distribution and syndication partnerships drive traffic
to ABOUT.COM. Through these partnerships, we typically provide content to a
partner's web site, and users can then link to ABOUT.COM for the full feature or
additional information on that topic. The flexibility and breadth of our content
enables us to partner with a broad range of Internet companies, including the
following:

    - Search engines and Internet directories such as AltaVista, Dogpile,
      GoTo.com, Metacrawler, Netscape Communications' NetSearch and RealNames;

    - Internet service providers such as BellSouth.net;

    - Content web sites such as CNN.com and Weather.com; and

    - Broadband cable-related sites such as AMC American Pop, American Movie
      Classics, Bravo, Home Box Office, Independent Film Channel,
      LifetimeTV.com, Romance Classics and Showtime.

    These agreements typically require us to make payments that are either fixed
or are based on the amount of user traffic directed from the partner's site to
ABOUT.COM. In addition, through our recently established affiliate marketing
program, third-party web sites can populate their site with our features and
content, and Internet users are linked to ABOUT.COM for additional content.
These agreements will require us to make payments that are based on the amount
of user traffic directed from the affiliate's site to ABOUT.COM. Through our
syndication partnerships, we provide content to a partner's web site for a fee.
We intend to continue to pursue distribution and syndication partnerships with
leading Internet service providers and popular web sites in the future.

ADVERTISING AND ELECTRONIC COMMERCE

    We believe our network provides a highly targeted platform for advertising
and electronic commerce over a broad range of consumer and business topics.
Sales of advertisements on ABOUT.COM

                                       31
<PAGE>
are being generated primarily by our internal advertising sales organization.
Our internal advertising sales force maintains close relationships with
advertisers by consulting regularly with them on design and placement of their
Internet-based advertising, by providing them with advertising measurement
analysis and by providing a high level of customer support. As of August 31,
1999, we had an internal advertising sales organization consisting of 35
professionals located in New York, Los Angeles and San Francisco. We intend to
increase the size of our internal advertising sales organization.

    Our advertisers typically enter into agreements with terms of between two
months and two years, under which they generally receive a guaranteed number of
impressions at a fixed rate. In some cases, these agreements entitle us to a
share of revenues generated by sales of merchandise or services over a
particular threshold resulting from direct links from ABOUT.COM. Advertisers
have significant flexibility in determining the placement of their
advertisements based on the level of targeting they want to achieve. We offer
numerous sizes and types of advertising placement, including banner
advertisements, button advertisements and text links. We also offer sponsorship
programs and other promotional opportunities to build brand awareness and to
drive traffic to the web sites of our advertisers.

    The following is a list of some of the advertisers that have advertised on
ABOUT.COM during the first three quarters of 1999:

<TABLE>

BBQ.com                IBM

</TABLE>

                                       32
<PAGE>
    For several of our advertisers we have developed electronic commerce
promotions that integrate original content from ABOUT.COM with traditional
commercial advertising. We provide links to these integrated promotional sites
by prominently displaying the advertisement within ABOUT.COM. For example, we
have developed an online book store for Borders.com that integrates Borders'
book offerings with book reviews independently written by ABOUT.COM guides. As
part of this promotion, guides can make recommendations for books related to
their topic-specific sites that are linked to the Borders online book store. As
of August 31, 1999, over 550 guides had created annotated links to Borders book
store within their topic-specific sites. We believe these features create a more
relevant, engaging purchasing vehicle for users, while enhancing the value of
our network as an electronic commerce platform.

BRAND PROMOTION AND MARKETING

    In May 1999, we changed our name from MiningCo.com to About.com. In support
of this initiative, we conducted a significant national print and television
campaign.

    We believe that an aggressive brand promotion campaign will increase usage
of ABOUT.COM, as well as attract additional advertisers and electronic commerce
partners. We market our service through online advertising and have been
advertising in selected cities through traditional offline media, including
outdoor and radio advertisements and a national trade magazine campaign. We also
utilize public relations, trade shows and ongoing customer communications
programs. We intend to expand our marketing and brand promotion initiatives.

GUIDE MANAGEMENT

    As of August 31, 1999, our 674 guides, 478 of whom had been guides for at
least one year, were located in over 40 states and 18 countries. Through the
topic-specific sites, these independent contractors create annotated Internet
directories and original content, and moderate personal interaction tools such
as bulletin boards and chat. As of August 31, 1999, the guides were directly
supported by a team of 50 of our employees, including 26 editors. Editors
regularly monitor each topic-specific site to assess the relevance and quality
of its features, the management of personal interaction tools and compliance
with our policies. Editors also provide weekly newsletters and host chats with
guides to better communicate topic-specific site tips, including news, ideas for
improving sites and marketing information.

    APPLICATION AND TRAINING.  We recruit our guides through various methods,
including searches of the Internet for topic-specific sites run by individuals,
user inquiries, referrals by existing guides and Internet-based classified job
listings. Guide applications are available on ABOUT.COM and are screened by a
team of editors who read and evaluate the applicant's sample feature article and
Internet directories, as well as assess the applicant's knowledge of his or her
topic. Once an application is accepted, the applicant becomes an associate guide
and is placed into a four-week preliminary training class. During this period,
the associate guide is taught how to construct and maintain one of our
topic-specific sites, how to administer a bulletin board and chat, and how to
create features and newsletters. At the same time, we review the associate
guide's feature articles and directories for quality of organization,
annotation, completeness, direct linking to relevant pages within web sites and
writing skills. If the associate guide meets our qualification criteria at the
end of this period, his or her web site becomes a live topic-specific site and
the associate guide becomes a guide.

    Following successful completion of the training class, each guide is placed
in a comprehensive 12-week follow-on training and quality control process.
During this period, the editorial staff provides guides with feedback on the
strengths and weaknesses of their sites and makes recommendations for further
improvements of both quality and consistency. At the end of this 12-week period,
the quality of

                                       33
<PAGE>
the guide's site is rated. This rating is regularly revisited by the editors and
is one of the factors that determines a guide's minimum compensation.

    GUIDE CONTRACTS.  Pursuant to the standard guide contract, we are granted an
exclusive perpetual license to use guide-developed ABOUT.COM content on the
Internet and on any other commercial online service, subject to the guide
sharing in any associated revenue. In addition, we also retain the right, on a
non-exclusive basis, to use the content in any offline media, subject to the
guide sharing in any associated revenue. The guides have agreed to share with us
any revenue derived from their use of this content in any offline media. The
standard guide contract is terminable by either party upon 15 days' prior
written notice.

    GUIDE COMPENSATION.  Guides are currently compensated based on the greater
of a monthly guarantee or a percentage of net advertising revenues generated by
the topic-specific sites on ABOUT.COM, which we distribute among the guides
based on the user traffic on each guide's respective topic-specific site. By
compensating guides based on the net advertising revenues of topic-specific
sites, the guides are provided incentives to help and encourage each other.
Guides are also currently entitled to share a percentage of net transaction
revenues and net syndication revenues. In addition, we may distribute a
discretionary bonus to guides based on outstanding content, exceptional
performance and longevity.

    ONLINE GUIDE LOUNGE.  We provide relevant information to the guides through
a password-protected web site and via bulletin boards, chat and newsletters. The
guide lounge includes a library of reference information for the guides,
including our policies, publishing regulations and other useful information. The
guide lounge also provides the guides with a platform for communicating with
each other.

OUR PROPRIETARY TEMPLATE

    We have developed a proprietary template for the consistent presentation of
each topic-specific site's navigational features, content and personal
interaction tools. This template includes:

    - a welcome page that promotes various aspects of a topic-specific site,
      including the guide's latest featured article;

    - the name, e-mail address and photograph of the guide managing the
      topic-specific site;

    - an Internet directory that provides annotated links to the guide's
      selected third-party Internet content;

    - an archive of the guide's original content features;

    - a guide-created e-mail newsletter to allow the site's users to stay in
      touch with developments on the site and the site's particular topic;

    - a guide-moderated bulletin board where users can post questions, opinions
      or information;

    - a chat room for users that is used for regularly scheduled, guide-hosted
      chat sessions and unscheduled open chat;

    - an events calendar maintained by the guide that lists various activities
      and events related to the site's specific topic; and

    - a guide biography page that provides users with background information
      regarding the guide.

    Our editors regularly identify noteworthy content features within the
topic-specific sites and combine this content in a variety of formats for users.
This content is used to create daily features on

                                       34
<PAGE>
pages within ABOUT.COM (e.g., "ABOUT.COM TODAY"), and to develop e-mail
newsletters. We believe that these features and newsletters are effective site
promotion and user retention tools.

OPERATING INFRASTRUCTURE

    Our operating infrastructure is designed to provide timely and efficient
delivery of the network to customers. Each page on a topic-specific site is
generated and delivered by one of our web and applications servers. Our network
uses FreeBSD, Solaris and Microsoft Windows NT for operating systems, and Apache
and IIS for Internet web server software. Our internal programming efforts are
written using a broad spectrum of programming languages.

    The administrative control center is our patented Internet-based site
management environment. This center enables our guides to remotely manage their
topic-specific sites at any time via a password-protected interface in order to
preview and upload content, view usage and feedback reports, and access
administrative tools for newsletters, chat, bulletin boards and events
calendars.

    In January 1998, we entered into an Internet-hosting agreement with
GlobalCenter to maintain all of our production servers at GlobalCenter's
Manhattan Data Center. This agreement was extended in January 1999 and is
terminable by either party upon 90 days' notice. GlobalCenter provides
comprehensive facilities management services, including human and technical
monitoring of all production servers 24 hours per day, seven days per week.
GlobalCenter provides the means of connectivity for ABOUT.COM's servers to
end-users via the Internet through high capacity transmission wires. These
connections link to many different parts of the Internet via a combination of
public and private peering agreements. The facility has two independent power
supplies, which are battery-powered, as well as two independent diesel
generators designed to provide power to these systems within seconds of a power
outage. The diesel generators can supply the data center's power for nine days
before refueling is required. GlobalCenter does not guarantee that our Internet
access will be uninterrupted, error-free or secure. Our operations are dependent
on GlobalCenter's ability to protect both its and our systems against damage
from fire, power loss, water damage, telecommunications failures, vandalism and
other malicious acts, and similar unexpected adverse events. Any disruption in
the Internet access provided by GlobalCenter could have a material adverse
effect on our business, results of operations and financial condition.

    ABOUT.COM must accommodate a high volume of traffic and has in the past and
may in the future experience slower response times and system downtime for a
variety of reasons. An increase in volume of users accessing ABOUT.COM could
lead to systems failures or slower response times and adversely affect
advertising revenues. Users may become dissatisfied by any system failure that
interrupts our ability to provide ABOUT.COM to them or results in slower
response time. ABOUT.COM could also be affected by computer viruses, electronic
break-ins or other similar disruptions. Our insurance policies have low coverage
limits and therefore insurance may not adequately compensate us for any losses
that may occur due to any failures in our system or interruptions in our
service. We are in the process of developing a comprehensive disaster recovery
plan to respond to system failures. Our business, results of operations and
financial condition could be materially adversely affected by any damage or
failure that interrupts or delays our operations.

    All of our production data is copied to backup tapes each night and these
backup tapes are rotated to a third-party facility for off-site storage. We keep
all of our production servers behind packet-filtered routers and do not allow
any outside access to any administrative functions. Strict password management
and physical security measures are followed.

    Our users and guides depend on Internet service providers, online service
providers and other web site operators for access to ABOUT.COM. Each of these
providers and operators has experienced significant outages in the past, and
could experience outages, delays and other difficulties due to system failures
unrelated to our systems. Moreover, the Internet infrastructure may not be able
to support

                                       35
<PAGE>
continued growth in its use. Any of these problems could materially adversely
affect our business, results of operations and financial condition.

GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES

    GENERAL.  There are an increasing number of laws and regulations pertaining
to the Internet. In addition, a number of legislative and regulatory proposals
are under consideration by federal, state, local and foreign governments and
agencies. Laws or regulations may be adopted with respect to the Internet
relating to liability for information retrieved from or transmitted over the
Internet, online content regulation, user privacy, taxation and quality of
products and services. Moreover, the applicability to the Internet of existing
laws governing issues such as intellectual property ownership and infringement,
copyright, trademark, trade secret, obscenity, libel, employment and personal
privacy is uncertain and developing. Any new legislation or regulation, or the
application or interpretation of existing laws, may decrease the growth in the
use of the Internet, which could in turn decrease the demand for our network,
increase our cost of doing business or otherwise have a material adverse effect
on our business, results of operations and financial condition.

    LIABILITY FOR INFORMATION RETRIEVED FROM ABOUT.COM AND FROM THE
INTERNET.  Content may be accessed on ABOUT.COM or on the web sites of our
distribution or syndication partners, and this content may be downloaded by
users and subsequently transmitted to others over the Internet. This could
result in claims against us based on a variety of theories, including
defamation, obscenity, negligence, copyright or trademark infringement or other
theories based on the nature, publication and distribution of this content.
These types of claims have been brought, sometimes successfully, against
providers of Internet services in the past. We could also be exposed to
liability with respect to third-party content that may be posted by users in
chat rooms or bulletin boards offered on the topic-specific sites. If any
information, including information deemed to constitute professional advice such
as legal, medical, financial or investment advice, provided on ABOUT.COM
contains errors or false or misleading information, third parties could make
claims against us for losses incurred in reliance on such information. ABOUT.COM
contains approximately 500,000 human-filtered annotated links to other web
sites. As a result, we may be subject to claims alleging that, by directly or
indirectly providing links to other web sites, we are is liable for copyright or
trademark infringement or the wrongful actions of third parties through their
respective web sites.

    The Communications Decency Act of 1996, or CDA, was enacted to prohibit the
transmission over the Internet of indecent, obscene or offensive content. While
selected parts of the CDA have been deemed unconstitutional, provisions
protecting providers of Internet services from claims related to third-party
content remain effective. Under the CDA, a provider of Internet services will
generally not be treated as a publisher or speaker of any information available
on its service but provided by a third-party content provider unless the
provider of Internet services exerts editorial control over the content or
embraces the content as its own. The Digital Millennium Act of 1998 provides
additional safe harbor defenses for Internet service providers under similar
conditions and upon compliance with procedural requirements specified in the
act. Our activities may prevent us from being able to take advantage of these
safe harbor provisions. In particular, while we do not edit the guide-developed
content prior to its availability on ABOUT.COM and only monitor this content to
ensure compliance with our policies, we may be subject to claims that we are the
publisher of the content available on the topic-specific sites. In addition,
since we have exclusive online rights to all guide-developed content on
ABOUT.COM, we aggregate this content for use on ABOUT.COM and for syndication
and distribution to third-party web sites and electronic commerce partners. We
may be subject to claims that we are the publisher of this aggregated
guide-developed content and to the extent that we exercise editorial control
over the content available on any site within our network, we increase the risk
that we will be found to be the publisher or speaker of that content. While we
attempt to reduce our exposure to this potential liability

                                       36
<PAGE>
through, among other things, provisions in guide agreements, user policies and
disclaimers, the enforceability and effectiveness of such measures are
uncertain.

    Our general liability insurance may not cover all potential claims to which
we are exposed and may not be adequate to indemnify us 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 our
business, results of operations and financial condition. Even if these claims do
not result in liability, we could incur significant costs in investigating and
defending against these claims. Potential liability for information disseminated
through ABOUT.COM could lead us to implement measures to reduce our exposure to
such liability, which may require the expenditure of substantial resources and
limit the attractiveness of our network to users.

    STATUS OF THE GUIDES AS INDEPENDENT CONTRACTORS.  We treat the guides as
independent contractors for tax and employee benefit purposes. One or more
jurisdictions may deem the guides to be our employees rather than independent
contractors and seek to impose taxes, interest and penalties on us. We could
have substantial tax and employee benefit liabilities if it were ultimately
determined that the guides are our employees. See "Risks Factors--We could incur
significant withholding taxes and employee benefits expenses if the guides were
deemed to be our employees rather than independent contractors."

    ONLINE CONTENT REGULATIONS.  Several federal, state and foreign statutes
prohibit the transmission of indecent, obscene or offensive content over the
Internet to particular groups of persons. Our network includes links to sites
with adult content. In addition, pending legislation seeks to ban Internet
gambling and federal and state officials have taken action against businesses
that operate Internet gambling activities. The enforcement of these statutes and
initiatives, and any future enforcement activities, statutes and initiatives,
may result in limitations on the type of content and advertisements available on
ABOUT.COM. Legislation regulating online content could dampen the growth in use
of the Internet generally and decrease the acceptance of the Internet as an
advertising and electronic commerce medium, which could have a material adverse
effect on our business, results of operations and financial condition.

    PRIVACY CONCERNS.  The Federal Trade Commission, or FTC, is considering
adopting regulations regarding the collection and use of personal identifying
information obtained from individuals when accessing web sites, with particular
emphasis on access by minors. These regulations may include requirements that
companies establish certain procedures to, among other things:

    - give adequate notice to users regarding information collection and
      disclosure practices;

    - provide users with the ability to have personal identifying information
      deleted from a company's database;

    - provide users with access to their personal information and with the
      ability to rectify inaccurate information;

    - clearly identify affiliations or a lack thereof with third parties that
      may collect information or sponsor activities on a company's web site; and

    - obtain express parental consent prior to collecting and using personal
      identifying information obtained from children under 13 years of age.

    These regulations may also include enforcement and redress provisions. While
we are implementing programs designed to enhance the protection of the privacy
of our users, including children, these programs may not conform with any
regulations adopted by the FTC. Moreover, even in the absence of those
regulations, the FTC has begun investigations into the privacy practices of
companies that collect information on the Internet. One investigation resulted
in a consent decree

                                       37
<PAGE>
pursuant to which an Internet company agreed to establish programs to implement
the principles noted above. We may become subject to a similar investigation, or
the FTC's regulatory and enforcement efforts may adversely affect our ability to
collect demographic and personal information from users, which could have an
adverse effect on our ability to provide highly targeted opportunities for
advertisers and electronic commerce marketers. Any of these developments would
have a material adverse effect on our business, results of operations and
financial condition.

    It is also possible that cookies, or 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, which are used to track demographic
information and to target advertising, may become subject to laws limiting or
prohibiting their use. 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 our use of cookies could limit the effectiveness of our targeting
of advertisements, which could have a material adverse effect on our business,
results of operations and financial condition.

    The European Union, or EU, has adopted a directive that imposes restrictions
on the collection and use of personal data. Under the directive, EU citizens are
guaranteed rights to access their data, rights to know where the data
originated, rights to have inaccurate data rectified, rights to recourse in the
event of unlawful processing and rights to withhold permission to use their data
for direct marketing. The directive could, among other things, affect U.S.
companies that collect information over the Internet from individuals in EU
member countries, and may impose restrictions that are more stringent than
current Internet privacy standard in the United States. In particular, companies
with offices located in EU countries will not be allowed to send personal
information to countries that do not maintain adequate standards of privacy. The
directive does not, however, define what standards of privacy are adequate. As a
result, the directive may adversely affect the activities of entities such as us
that engage in data collection from users in EU member countries.

    DATA PROTECTION.  Legislative proposals made by the federal government would
afford broader protection to owners of databases of information such as stock
quotes and sports scores. This protection already exists in the EU. If enacted,
this legislation could result in an increase in the price of services that
provide data to web sites and could create potential liability for unauthorized
use of these data. Either of these possibilities could have a material adverse
effect on our business, results of operations and financial condition.

    INTERNET TAXATION. A number of legislative proposals have been made at the
federal, state and local level, and by certain foreign governments, 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. Although
Congress recently placed a three-year moratorium on state and local taxes on
Internet access or on discriminatory taxes on electronic commerce, existing
state or local laws were expressly excepted from this moratorium. Further, once
this moratorium is lifted, some type of federal and/or state taxes may be
imposed upon Internet commerce. This legislation, or other attempts at
regulating commerce over the Internet, may substantially impede the growth of
commerce on the Internet and, as a result, adversely affect our opportunity to
derive financial benefit from those activities.

    REVENUE SHARING ARRANGEMENTS.  We enter into agreements with advertisers
under which we may be entitled to receive a share of revenues generated from the
purchase of goods and services through direct links from ABOUT.COM. These
agreements may expose us to additional legal risks and uncertainties, including
potential liabilities to customers of those products and services by virtue of
our involvement in providing access to those products or services, even if we do
not provide those products or services ourselves. Any indemnification provided
to us in our agreements with these parties, if available, may not be adequate.

                                       38
<PAGE>
    DOMAIN NAMES.  Domain names are Internet "addresses." The current system for
registering, allocating and managing domain names has been the subject of
litigation, including trademark litigation, and of proposed regulatory reform.
We have registered the domain name "ABOUT.COM." Although we are seeking to
register "ABOUT.COM" as a trademark in the United States, we may not
successfully obtain the registration and third parties may bring claims for
infringement against us for the use of this trademark. There can be no assurance
that our domain names will not lose their value, or that we will not have to
obtain entirely new domain names in addition to or in lieu of our current domain
names if reform efforts result in a restructuring in the current system.

    JURISDICTIONS.  Due to the global nature of the Internet, it is possible
that, although transmissions by us over the Internet originate primarily in New
York, the governments of other states and foreign countries might attempt to
regulate our transmissions or prosecute us for violations of their laws. These
laws may be modified, or new laws enacted, in the future. Any of the foregoing
developments could have a material adverse effect on our business, results of
operations and financial condition. In addition, as our network is available
over the Internet in multiple states and foreign countries, these jurisdictions
may claim that we are required to qualify to do business as a foreign
corporation in each of these states or foreign countries. We are qualified to do
business only in California, Georgia, Minnesota and New York, and failure by us
to qualify as a foreign corporation in a jurisdiction where we are required to
do so could subject us to taxes and penalties and could result in our inability
to enforce contracts in these jurisdictions. Any new legislation or regulation,
the application of laws and regulations from jurisdictions whose laws do not
currently apply to our business, or the application of existing laws and
regulations to the Internet and other online services could have a material
adverse effect on our business, results of operations and financial condition.

INTELLECTUAL PROPERTY

    We seek to protect our proprietary rights, but our actions may be inadequate
to protect our patents, trademarks or other proprietary rights or to prevent
others from claiming violations of their proprietary rights. We have one United
States patent, four patent applications on file with the United States Patent
and Trademark Office and one international patent application. We enter into
confidentiality agreements with our material employees, guides, consultants and
strategic partners, and generally controls access to and distribution of our
proprietary information. Despite our efforts to protect our proprietary rights
from unauthorized use or disclosure, parties may attempt to disclose, obtain or
use our proprietary information. The steps we have taken may not prevent
misappropriation of its proprietary information. Third parties may infringe or
misappropriate our proprietary rights, which could have a material adverse
affect on our business, results of operations and financial condition. The
validity, enforceability and scope of protection of proprietary rights in
Internet-related industries is uncertain and still evolving.

    Furthermore, third parties may assert infringement claims against us. From
time to time we have been, and we expect to continue to be, subject to claims in
the ordinary course of our business, including claims of alleged infringement of
the trademarks and other intellectual property rights of third parties by us or
our guides. These claims and any resultant litigation, should it occur, could
subject us to significant liability for damages and could result in the
invalidation of our proprietary rights. In addition, even if we prevail, any
litigation could be time-consuming and expensive to defend, and could result in
the diversion of management's time and attention, any of which could materially
adversely affect our business, results of operations and financial condition.
Any claims from third parties may also result in limitations on our ability to
use the trademarks and other intellectual property subject to those claims
unless we enter into agreements with the third parties responsible for those
claims, which may be unavailable on commercially reasonable terms.

COMPETITION

    We compete for users, advertisers and electronic commerce marketers with a
wide range of companies including the following:

    - Internet "portal" companies, including Excite, Lycos and Yahoo!;

    - Internet search engines and directories, including AskJeeves and
      LookSmart;

    - online content web sites, including C/net, ESPN.com and ZDNet.com;

    - online community web sites, including iVillage;

    - online personal homepage services, including GeoCities and theglobe.com;

    - publishers and distributors of television, radio and print, including CBS,
      Disney, NBC and Time Warner;

    - general purpose consumer online services, including America Online and
      Microsoft Network; and

    - web sites maintained by Internet service providers, including AT&T
      WorldNet, EarthLink and MindSpring.

    We believe that our ability to compete depends on many factors, many of
which are outside of our control. These factors include the quality of content
provided by us and our competitors, the ease of use of services developed either
by us or our competitors, the timing and market acceptance of new and enhanced
services developed either by us or our competitors, and sales and marketing
efforts of us and our competitors.

    We also compete with television, radio, cable and print (traditional
advertising media) for a share of advertisers' total advertising budgets. If
advertisers perceive the Internet or ABOUT.COM to be a limited or ineffective
advertising medium, advertisers may be reluctant to devote a significant portion
of their advertising budget to Internet advertising or to advertise on
ABOUT.COM.

    Please see "Risk Factors--We may not be able to compete successfully" for a
more detailed description of the risks of competition.

EMPLOYEES AND GUIDES

    As of August 31, 1999, we had 211 full-time employees, including 77 in
marketing and sales, 54 in content, editorial and guide support, 22 in finance
and administration and 58 in product development, operations and technical
support. As of August 31, 1999, we had 674 guides and an additional 81 guides in
training. None of the guides are employed by us, but rather they are engaged by
us as independent contractors. None of our employees are represented by a union.
We believe our relationship with our employees and the guides is good.

FACILITIES

    We are headquartered at 220 East 42nd Street, New York, New York, where we
lease an aggregate of approximately 42,000 square feet of space covering three
floors. The leases on these floors expire between 2000 and 2003. We also entered
into a six-month lease for approximately 3,000 square feet of commercial space
in Westchester, New York. We currently anticipate that we will require
additional space as more personnel are hired and we are actively searching for
larger space in New York City.

    We also lease a sales office located at 120 Montgomery Street, San
Francisco, California. The lease expires in July 2002 and is for approximately
3,515 square feet. In addition, we lease a product development office at 360
North Robert Street, St. Paul, Minnesota that expires in 2002 and covers
approximately 1,730 square feet.

LEGAL PROCEEDINGS

OPTION GRANTS IN LAST YEAR

    The following table sets forth information regarding options granted to the
named executive officers during the year ended December 31, 1998. Each option
represents the right to purchase one share of common stock and was granted under
our stock option plan. These options become exercisable at a rate of 25%
following one year from the date of grant with the remainder vesting ratably for
36 months thereafter. We have not granted any stock appreciation rights.

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

(1) During the year ended December 31, 1998, we granted options to purchase a
    total of 415,611 shares of common stock to employees.

(2) There was no public market for the common stock during 1998. For purposes of
    this table, the initial public offering price of $25.00 per share has been
    assumed to be the market price at the date of grant.

(3) Amounts in these columns represent hypothetical gains that could be achieved
    for the respective options if exercised at the end of the option term. The
    0%, 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the SEC and do not represent our estimate or
    projection of our future common stock prices. Actual gains, if any, on stock
    option exercises depend on our future performance and overall stock market
    conditions. The amounts reflected in the table may be more or less than the
    amounts actually achieved.

AGGREGATED OPTION EXERCISES IN THE YEAR ENDED DECEMBER 31, 1998 AND YEAR-END
  OPTION VALUES

    The following table sets forth information concerning the value realized
upon exercise of options during 1998 and the number and value of unexercised
options held by each of the named executive officers at December 31, 1998. There
was no public trading market for our common stock as of December 31, 1998.
Accordingly, the values set forth below have been calculated on the basis of the
initial public offering price of $25.00 per share, less the applicable exercise
price per share, multiplied by the number of shares underlying the options.

(1) Solely for purposes of this calculation, the fair market value of our common
    stock at the time of the exercise was deemed to be the initial public
    offering price of $25.00 per share. The exercise price of the options was
    $0.51 per share.

(2) Options to purchase 62,300 shares of common stock accelerated and became
    exercisable when our initial public offering closed. This resulted in an
    increase in the value of Mr. Day's unexercised in-the-money exercisable
    options of $1,525,727.

AMENDED AND RESTATED 1998 STOCK OPTION/STOCK ISSUANCE PLAN

    Our amended and restated 1998 stock option/stock issuance plan serves as the
successor equity incentive program to our 1997 employee incentive stock option
plan. The 1998 stock option/stock issuance plan became effective on July 2, 1998
upon adoption by the board of directors and was approved by the stockholders on
the same day. On February 1, 1999 the board approved the amended and restated
1998 stock option/stock issuance plan, which was approved by the stockholders on
the same day. A total of 1,886,800 shares of common stock were initially
authorized for issuance under the stock option plan. This initial share reserve
was comprised of the shares that remained available for issuance under the old
stock option plan on the effective date of the new stock option plan, including
the shares subject to outstanding options under that plan plus an increase of
890,000 shares. On February 5, 1999, the board authorized, and the stockholders
approved, an increase of 1,338,085 shares. Outstanding options under the old
stock option plan were incorporated into the new stock option plan upon the date
of the approval of the new stock option plan, and no further option grants are
being made under the old stock option plan. The incorporated options will
continue to be governed by their existing terms, unless the plan administrator
elects to extend one or more features of the new stock option plan to those
options.

    As of September 30, 1999 there were outstanding options to purchase a total
of 2,778,071 shares of common stock under the 1998 stock option plan, of which
options to purchase 833,006 shares were then exercisable. Since we have filed a
registration statement on Form S-8, any shares issued upon exercise of these
options will be immediately available for sale in the public market, subject to
the terms of any lock-up agreements entered into between these optionholders and
the underwriters.

    Except as otherwise noted in the previous paragraph or below, the
outstanding options under the old stock option plan contain substantially the
same terms and conditions summarized below for the discretionary option grant
program in effect under the 1998 stock option plan. The 1998 stock option plan
is divided into three separate components:

    - the discretionary option grant program under which eligible individuals in
      our employ or service (including officers, non-employee members of the
      board of directors, consultants and guides) may, at the discretion of the
      plan administrator, be granted options to purchase shares of common stock
      at an exercise price determined by the plan administrator;

    - the stock issuance program under which those individuals may, in the plan
      administrator's discretion, be issued shares of common stock directly,
      through the purchase of those shares at a price determined by the plan
      administrator or as a bonus tied to the performance of services; and

    - 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 100% of the fair market value of those shares on
      the grant date.

    In no event may any one participant in the 1998 stock option plan receive
option grants or direct stock issuances for more than 267,000 shares in the
aggregate per calendar year. Under the old stock option plan, only employees
were eligible to receive option grants and the exercise price could not be less
than the fair market value per share on the grant date.

    The discretionary option grant program and the stock issuance program are
administered by the compensation committee of the board of directors. The
compensation committee as plan administrator

                                       47
<PAGE>
has complete discretion to determine which eligible individuals are to receive
option grants or stock issuances, the time or times when option grants or stock
issuances are to be made, the number of shares subject to each 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 granted option is to remain outstanding. The administration of the
automatic option grant program is self-executing in accordance with the express
provisions of that program. Under the old stock option plan, only incentive
stock options were granted.

    The exercise price for the shares of common stock subject to option grants
made under the 1998 stock option 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 participants in the 1998 stock option plan in connection with
their acquisition of shares, by allowing those individuals to deliver a
full-recourse, interest-bearing promissory note in payment of the option
exercise price and any associated withholding taxes incurred in connection with
that acquisition.

    In the event of an acquisition of us, whether by merger or asset sale or a
sale by the stockholders of more than 50% of the total voting power of us that
is recommended by the board of directors, each outstanding option under the
discretionary option grant program that is not to be assumed by the successor
corporation or otherwise continued will automatically accelerate in full, and
all repurchase rights relating to shares under the discretionary option grant
program and stock issuance program will immediately lapse, except to the extent
our repurchase rights with respect to those shares are to be assigned to the
successor corporation or otherwise continued in effect. Under the 1998 stock
option plan, the plan administrator has the authority at the time of grant to
provide that the shares subject to options granted under the discretionary
option grant program will automatically vest:

    - upon an acquisition of us whether or not those options are assumed or
      continued, or

    - upon a hostile change in control of us effected through:

       - a tender offer for more than 50% of our outstanding voting stock, or

       - a proxy contest for the election of the board of directors, or

       - if the individual is terminated involuntarily or resigns for good
         reason within 12 months following an acquisition in which the
         individual's options were assumed or otherwise continued in effect or
         following a hostile change in control.

The vesting of outstanding shares under the stock issuance program may be
accelerated upon similar terms and conditions.

    Stock appreciation rights are authorized for issuance under the
discretionary option grant program, which rights provide the holders with the
election to surrender their outstanding options for an appreciation distribution
from us equal to the excess of the fair market value of the vested shares of
common stock subject to the surrendered option over the aggregate exercise price
payable for those shares. This appreciation distribution may be made in cash or
in shares of common stock. There are currently no outstanding stock appreciation
rights.

    The plan administrator has the authority to effect the cancellation of
outstanding options under the discretionary option grant program (including
options incorporated from the old stock option plan) in return for the grant of
new options for the same or different number of option shares with an exercise
price per share based upon the fair market value of the common stock on the new
grant date.

    Under the automatic option grant program, non-employee board of directors
members will be entitled to receive option grants. Each automatic grant will
have an exercise price equal to the fair

                                       48
<PAGE>
market value per share of common stock on the grant date and will have a maximum
term of 10 years, subject to earlier termination following the optionee's
cessation of board of directors service. Each automatic option will be
immediately exercisable; however, any shares purchased upon exercise of the
option will be subject to repurchase, at the option exercise price paid per
share, should the optionee's service as a non-employee member of the board of
directors cease prior to vesting in the shares. Each 20,000-share grant will
vest over a four-year period. Each annual 5,000-share grant will vest upon the
optionee's completion of one year of board of directors service measured from
the grant date. However, each outstanding option will immediately vest upon a
change in control of us or the death or disability of the optionee while serving
as a board of directors member. Please see "--Director Compensation."

    The board of directors may amend or modify the 1998 stock option plan at any
time, subject to any required stockholder approval. The 1998 stock option plan
will terminate on the earliest of:

    - July 1, 2008;

    - the date on which all shares available for issuance under the 1998 stock
      option plan have been issued as fully-vested shares; and

    - the termination of all outstanding options in connection with particular
      changes in control or ownership of us.

1999 NON-OFFICER STOCK OPTION/STOCK ISSUANCE PLAN

    The 1999 non-officer stock option/stock issuance plan was adopted by our
board of directors on August 20, 1999 and became effective upon that date. A
total of 400,000 shares of our common stock have been authorized for issuance
under this plan. This plan has two separate programs:

    - the discretionary option grant program, under which eligible individuals
      may be granted options to purchase shares of our common stock at an
      exercise price not less than the fair market value of those shares on the
      grant date; and

    - the stock issuance program, under which eligible individuals may be issued
      shares of common stock which will vest upon the attainment of performance
      milestones or upon the completion of a period of service or which are
      fully vested at issuance as a bonus for past services.

    The individuals eligible to participate in this plan include our employees
(other than officers) and any consultants we hire. This plan is administered by
the board or a committee appointed by our board. The committee will determine
which eligible individuals are to receive option grants or stock issuances under
this plan, the time or times when the grants or issuances are to be made, the
number of shares subject to each grant or issuance, the vesting schedule to be
in effect for the option grant or stock issuance and the maximum term for which
any granted option is to remain outstanding.

    The exercise price for any options granted under this plan may be paid in
cash or in shares of our 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.

    This plan includes the following change in control provisions which may
result in the accelerated vesting of outstanding option grants and stock
issuances:

    - In the event that we are acquired by merger, asset sale, or stock sale,
      each outstanding option under the discretionary option grant program which
      is not to be assumed by the successor corporation will immediately become
      exercisable for all the option shares, and all outstanding unvested shares
      will immediately vest, except to the extent our repurchase rights with
      respect to those shares are to be assigned to the successor corporation or
      the accelerated vesting is limited by the terms of the option grant.

                                       49
<PAGE>
    - The board will have complete discretion to grant one or more options which
      will become exercisable immediately prior to the change of control for all
      the option shares, whether or not those options are assumed in the
      acquisition.

    - The board may grant options such that the options will immediately vest if
      the optionee's services with us or the acquiring entity are subsequently
      terminated within a designated time period.

    - The board may grant options and structure repurchase rights so that the
      shares subject to those options or repurchase rights will immediately vest
      in connection with a successful tender offer for more than fifty percent
      of our outstanding voting stock or a change in the majority of our board
      through one or more contested elections. Such accelerated vesting may
      occur either at the time of such transaction or upon the subsequent
      termination of the individual's service within a designated time period.

    The board may amend or modify this plan at any time. The plan will terminate
no later than August 20, 2009.

1999 EMPLOYEE STOCK PURCHASE PLAN

    Our employee stock purchase plan became effective on March 22, 1999. The
purchase plan is designed to allow eligible employees of us and participating
subsidiaries to purchase shares of common stock, at semi-annual intervals,
through their periodic payroll deductions. As of September 30, 1999, a total of
125,000 shares of common stock were reserved for issuance under the purchase
plan.

    The purchase plan will be implemented in a series of successive purchase
periods, each with a duration of six months. Purchase periods will generally run
from the first business day in May to the last business day in October each year
and from the first business day in November to the last business day in April
the next year. However, the initial purchase period began on March 22, 1999 and
will end on October 31, 1999.

    Employees who are 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 are
eligible to enter the purchase plan on that start date.

    Payroll deductions may not exceed 15% of the participant's cash earnings.
The accumulated payroll deductions of each participant will be applied to the
purchase of shares on the participant's behalf on each purchase date. The
purchase price per share will equal 85% of the lower of the fair market value of
the common stock on the start of the purchase period or the fair market value on
the purchase date. No participant may purchase more than 500 shares on any
purchase date.

    In the event we are acquired by merger or asset sale, all outstanding
purchase rights will automatically be exercised immediately prior to the
effective date of the acquisition. The purchase price will be equal to 85% of
the lower of the fair market value per share of common stock on the start of the
purchase period in which that acquisition occurs or the fair market value per
share of common stock immediately prior to the acquisition.

    The purchase plan will terminate on the earliest of:

    - October 31, 2009;

    - the date on which all shares available for issuance under the purchase
      plan have been sold in accordance with the purchase plan; and

    - the date on which all purchase rights are exercised in connection with an
      acquisition of About.com by merger or asset sale

    Subject to stockholder approval for certain amendments, the board of
directors may at any time alter, suspend or discontinue the purchase plan.

SERIES A FINANCING

    Between March 1997 and January 1998, we issued convertible promissory notes
in an aggregate principal amount of $4,950,000 to a number of investors,
including the investors set forth in the table below. Pursuant to their terms,
the principal amount due on these notes was either automatically convertible
into shares of our capital stock upon the closing of our next equity financing
or due and payable on the earlier of the fifth anniversary of the delivery of
the notes or upon an event of default under the notes. These notes bore interest
at a variable rate equal to the prime rate published by a major financial
institution plus 2% per annum. On April 23, 1998, in consideration for the
cancellation of the principal amount of these notes and $70,000 in interest that
accrued on these notes prior to August 12, 1997, we issued to the noteholders a
total of 3,346,715 shares of Series A convertible preferred stock. The remaining
interest on these notes was evidenced by newly issued unsecured promissory notes
that, by their terms, were forgiven and cancelled upon the closing of our

                          DESCRIPTION OF CAPITAL STOCK

    Our authorized capital stock consists of 50,000,000 shares of common stock,
par value $.001 per share, and 5,000,000 shares of preferred stock, par value
$.001 per share.

COMMON STOCK

    As of September 30, 1999, there were 12,288,418 shares of common stock
outstanding and held of record by 117 stockholders.

    Holders of common stock are entitled to one vote for each share on all
matters submitted to a vote of stockholders. 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 dividends, if, as, and when declared by the board of directors out of
funds legally available for such purposes, subject to any dividend preferences
of any outstanding preferred stock. Upon our liquidation, dissolution or winding
up, the holders of common stock are entitled to share ratably in our assets
available for distribution, subject to the preferential rights of any
outstanding preferred stock. Holders of the common stock have no preemptive,
subscription, redemption or conversion rights. There are no shares of preferred
stock outstanding. 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 that we may designate and
issue in the future.

PREFERRED STOCK

    The board of directors has the authority, 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. The board of directors may fix or alter
the designations, preferences, rights and any qualifications, limitations or
restrictions of the shares of each of these series, including the dividend
rights, dividend rates, conversion rights, voting rights, terms of redemption,
redemption price or prices, liquidation preferences and the number of shares
constituting any series or designations of these series. We have no present
plans to issue any shares of preferred stock. Please see "--Anti-Takeover
Effects of Certain Provisions of Delaware Law and Our Certificate of
Incorporation and Bylaws."

OPTIONS

    Options to purchase a total of 3,624,885 shares of common stock may be
granted under the stock option plans. As of September 30, 1999, there were
outstanding under the stock option plans options to purchase a total of
2,778,071 shares of common stock, of which options to purchase 833,006 shares
were then exercisable. In addition, as of September 30, 1999, there were
outstanding options to purchase a total of 32,052 shares of common stock which
were not granted under the stock option plans, all of which were then
exercisable. Since we have filed a registration statement on Form S-8, any
shares issued upon exercise of these options will be immediately available for
sale in the public market, subject to the terms of any lock-up agreements
entered into between these optionholders and the underwriters. Please see "Risk
Factors--Future sales of common stock by our existing stockholders could
adversely affect our stock price", "Management--Amended and Restated 1998 Stock
Option/ Stock Issuance Plan" and "--1999 Non-Officer Stock Option/Stock Issuance
Plan."

COMMON STOCK WARRANTS

    As of September 30, 1999, there were outstanding warrants to purchase a
total of 65,860 shares of common stock at an average exercise price of $9.80 per
share. The warrants contain anti-dilution provisions providing for adjustments
of the exercise price and the number of shares of common stock underlying the
warrants upon the occurrence of any recapitalization, reclassification, stock
dividend, stock split, stock combination or similar transaction. The warrants
grant to their holders registration rights, described below, with respect to the
common stock issuable upon their exercise. Please see

                                       57
<PAGE>
"Risk Factors--Future sales of common stock by our existing stockholders could
adversely affect our stock price."

REGISTRATION RIGHTS

    Pursuant to the terms of the amended and restated investors' rights
agreement, some holders of shares of common stock are entitled to demand that we
register their shares for resale under the Securities Act. The holders of 50% or
more of the shares of common stock issued upon the conversion of each series of
convertible preferred stock are entitled to demand that we register their shares
under the Securities Act, subject to certain limitations. We are not required to
effect more than one demand registration for each group of holders. In addition,
these holders and Comcast are entitled to piggyback registration rights with
respect to the registration of shares of common stock under the Securities Act.
In the event that we propose to register any shares of common stock under the
Securities Act, including in connection with this offering, the holders of
shares having piggyback rights are entitled to receive notice of that
registration and are entitled to include their shares in the registration,
subject to limitations. Further, at any time after we become eligible to file a
registration statement on Form S-3, the holders of a portion of our shares of
common stock may require us to file on two occasions Form S-3 registration
statements under the Securities Act with respect to their shares of common
stock. These registration rights are subject to conditions and limitations,
among them the right of the underwriters of an offering to limit the number of
shares of common stock to be included in the registration. We are generally
required to bear all of the expenses of these registrations, except underwriting
discounts and selling commissions. Registration of any of the shares of common
stock held by security holders with registration rights would result in those
shares becoming freely tradable without restriction under the Securities Act.

ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF DELAWARE LAW AND OUR CERTIFICATE
  OF INCORPORATION AND BYLAWS

    We are subject to the provisions of Section 203 of the Delaware General
Corporation Law, or DGCL. Section 203 of the DGCL generally 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 that 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
exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, fifteen percent
(15%) or more of a corporation's voting stock. This statute could prohibit or
delay the accomplishment of mergers or other takeover or change in control
attempts and, accordingly, may discourage attempts to acquire us.

    In addition, certain provisions of our certificate and bylaws 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.

    BOARD OF DIRECTORS VACANCIES.  The certificate authorizes the board of
directors to fill vacant directorships or increase the size of the board of
directors. This may deter a stockholder from removing incumbent directors and
simultaneously gaining control of the board of directors by filling the
vacancies created by that removal with its own nominees.

    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 our stockholders may be called only by the
chairman of the board of directors or a majority of the board of directors.

                                       58
<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 deliver a written notice
to our principal executive offices within a prescribed time period. The bylaws
also specify 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, subject to limitations imposed by the Nasdaq National
Market. These additional shares may be utilized for a variety of corporate
purposes, including future public offerings to raise additional capital,
acquisitions and employee benefit plans. The existence of authorized but
unissued and unreserved common stock and preferred stock could render more
difficult or discourage an attempt to obtain control of us by means of a proxy
contest, tender offer, merger or otherwise.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

    Our certificate provides that, except to the extent prohibited by the DGCL,
our directors shall not be personally liable to us or our stockholders for
monetary damages for any breach of fiduciary duty as our directors. Under the
DGCL, the directors have a fiduciary duty to us that is not eliminated by this
provision of the certificate and, in appropriate circumstances, injunctions and
other nonmonetary relief will remain available. This provision also does not
affect the directors' responsibilities under any other laws, including the
Federal securities laws or state or Federal environmental laws.

    Section 145 of the DGCL enables 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. However, this provision does
not eliminate or limit the liability of a director:

    - for any breach of the director's duty of loyalty to the corporation or its
      stockholders,

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

    - for payments of dividends or approval of stock repurchases or redemptions
      that are prohibited by the DGCL or

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

    Our certificate provides that, except to the extent prohibited by DGCL, we
may 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, criminal, administrative or investigative, by reason of the fact
that the person is or was, or has agreed to become, a director or officer or is
or was serving, or has agreed to serve, at our request 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 that
person in connection with any threatened, pending or completed action, suit,
proceeding or appeal.

    We believe that the provisions of its certificate and bylaws and these
agreements are necessary to attract and retain qualified directors and executive
officers. Our bylaws also permit us to secure insurance on behalf of any
officer, director, employee or other agent for any liability arising out of his
or her actions, regardless of whether the DGCL would permit indemnification. We
have obtained liability insurance for our officers and directors.

    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent for which indemnification will be required
or permitted under the certificate. We are not aware of any threatened
litigation or proceeding that may result in a claim for indemnification.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for the common stock is American Stock
Transfer & Trust Company, New York, New York.

</TABLE>

    The underwriting agreement provides that the obligations of the underwriters
to purchase and accept delivery of the shares of common stock in this offering
require approval by their counsel of legal matters and other conditions. The
underwriters must purchase and accept delivery of all the shares of common stock
in the offering, other than those shares covered by the over-allotment option
described below, if they purchase any of the shares.

    The underwriters initially propose to offer some of the shares of common
stock directly to the public at the public offering price on the cover page of
this prospectus and some of the shares to dealers, including the underwriters,
at the public offering price less a concession not in excess of $      per
share. The underwriters may allow, and these dealers may re-allow to other
dealers, a concession not in excess of $      per share. After the initial
offering of the common stock, the representatives of the underwriters may change
the public offering price and other selling terms at any time without notice.

    The following table shows the underwriting fees to be paid to the
underwriters by us and the selling stockholders in this offering. These amounts
are shown assuming both no exercise and full exercise of the underwriters'
option to purchase additional shares of common stock.

    We and the selling stockholders have granted to the underwriters an option,
exercisable for 30 days after the date of this prospectus, to purchase, from
time to time, in whole or in part, up to an aggregate of 525,000 additional
shares of common stock at the public offering price less underwriting fees. The
underwriters may exercise this option solely to cover over-allotments, if any,
made in connection with this offering. To the extent that the underwriters
exercise this option, each underwriter will become obligated, under conditions
specified in the underwriting agreement, to purchase its pro rata portion of the
additional shares based on that underwriter's percentage underwriting commitment
as indicated in the preceding table.

    We and the selling stockholders have agreed to indemnify the underwriters
against civil liabilities specified in the underwriting agreement, including
liabilities under the Securities Act, or to contribute to payments that the
underwriters may be required to make because of these liabilities.

    We, all of our executive officers and directors, and all of the selling
stockholders have agreed, for a period of 90 days after the date of the
prospectus without the prior written consent of Donaldson, Lufkin & Jenrette,
not to:

    - offer, pledge, sell, contract to sell, sell any option or contract to
      purchase, purchase any option or contract to sell, grant any option, right
      or warrant to purchase or otherwise transfer or dispose of, directly or
      indirectly, any shares of common stock or any securities convertible into
      or exercisable or exchangeable for common stock; or

    - enter into any swap or other arrangement that transfers all or a portion
      of the economic consequences associated with the ownership of any common
      stock.

However, we may issue, and grant options to purchase, shares of common stock
under our option plans and our purchase plan. In addition, we may issue shares
of common stock in connection with any acquisition of another company if the
terms of that issuance provide that the common stock shall not be resold prior
to 90 days after the date of this prospectus without the prior written consent
of Donaldson, Lufkin & Jenrette.

    In addition, during this 90-day period, we have also agreed not to file any
registration statement for, and each of the executive officers, directors and
selling stockholders has agreed not to make any demand for or exercise any right
for, the registration of any shares of common stock or any securities
convertible into or exercisable or exchangeable for common stock without the
prior written consent of Donaldson, Lufkin & Jenrette, except for a registration
statement to register for resale the 400,000 shares reserved for issuance under
our 1999 Non-Officer Stock Option/Stock Issuance Plan.

    A copy of this prospectus in electronic format will be made available on the
Internet web sites hosted by E*OFFERING Corp. and E*TRADE Securities, Inc.
E*TRADE will accept conditional offers to purchase shares from all of its
customers that pass and complete an online eligibility profile. If the demand
for shares from the customers of E*TRADE exceeds the amount of shares allocated
to it, E*TRADE will use a random allocation methodology to distribute shares in
even lots of 100 shares per customer.

    Other than in the United States, no action has been taken by us, the selling
stockholders or the underwriters that would permit a public offering of the
shares of common stock offered by this prospectus in any jurisdiction where
action for that purpose is required. The shares of common stock offered by this
prospectus may not be offered or sold, directly or indirectly, nor may this
prospectus or any other offering material or advertisements associated with the
offer and sale of any shares of common stock offered by this prospectus be
distributed or published in any jurisdiction, except under circumstances that
will result in compliance with the applicable rules and regulations of that
jurisdiction. You should inform yourself about and observe any restrictions
relating to the offering of the common stock and the distribution of this
prospectus. This prospectus does not constitute an offer to sell or solicitation
of an offer to buy any shares of common stock offered by this prospectus in any
jurisdiction in which an offer or a solicitation is unlawful.

    The underwriters and dealers may engage in passive market making
transactions in the common stock in accordance with Rule 103 of Regulation M
promulgated by the Securities and Exchange Commission. In general, a passive
market maker may not bid for or purchase shares of common stock at a price that
exceeds the highest independent bid. In addition, the net daily purchases made
by any passive market maker generally may not exceed 30% of its average daily
trading volume in the common stock during a specified two-month period, or 200
shares, whichever is greater. A passive maker must identify passive market
making bids as such on the Nasdaq electronic inter-dealer reporting system.
Passive market making may stabilize or maintain the market price of the common
stock above independent market levels. Underwriters and dealers are not required
to engage in passive market making and may end passive market making activities
at any time.

    As a result of the offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the common stock.
Specifically, the underwriters may over-allot the offering, creating a syndicate
short position. The underwriters may bid for and purchase shares of common stock
in the open market to cover a syndicate short positions or to stabilize the
price of the common stock. In addition, the underwriting syndicate may reclaim
selling concessions from syndicate members if the syndicate repurchases
previously distributed common stock in syndicate covering transactions, in
stabilization transactions or in some other way or if Donaldson, Lufkin &
Jenrette receives a report that indicates clients of those syndicate members
have "flipped" shares of common stock. These activities may stabilize or
maintain the market price of the common stock above independent market levels.
The underwriters are not required to engage in these activities, and may end any
of these activities at any time.

                                 LEGAL MATTERS

    The validity of the shares of common stock offered by this prospectus will
be passed upon for us by Brobeck, Phleger & Harrison LLP, New York, New York,

The Board of Directors and Stockholders
About.com, Inc.:

    We have audited the accompanying balance sheets of About.com, Inc. as of

stockholders' deficit and cash flows for the period from June 27, 1996
(inception) to December 31, 1996 and for the years ended December 31, 1997 and
1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of About.com, Inc. as of
December 31, 1997 and 1998, and the results of its operations and its cash flows
for the period from June 27, 1996 (inception) to December 31, 1996 and for the
years ended December 31, 1997 and 1998 in conformity with generally accepted

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                  DECEMBER 31, 1997 AND 1998 AND JUNE 30, 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)

(1)  ORGANIZATION AND BUSINESS

    About.com, Inc. ("About.com" or the "Company") was incorporated in New York
on June 27, 1996 (inception) as General Internet Inc. and commenced operations
on that date. In December 1998, General Internet Inc. changed its corporate name
to MiningCo.com, Inc. and reincorporated in Delaware. In May 1999, MiningCo.com,
Inc. changed its corporate name to About.com, Inc. About.com's Internet service,
ABOUT.COM, is an Internet news, information and entertainment service.
About.com's primary revenue source is the sale of advertising.

    About.com's business is characterized by rapid technological change, new
product and service development and evolving industry standards. Inherent in the
Company's business are various risks and uncertainties, including its limited
operating history, uncertain profitability, history of losses, anticipated
continuing losses, the dependence on the Internet and risks associated with
Internet advertising.

(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

    (A) INITIAL PUBLIC OFFERING AND CONCURRENT PLACEMENT

    On February 23, 1999, About.com and Comcast Interactive Investments, Inc.
("Comcast") entered into a common stock purchase agreement pursuant to which
About.com agreed to sell $2,500,000 of common stock to Comcast. These common
shares were purchased directly from About.com in a private placement transaction
at a price of 93% of the initial public offering price per share (or $23.25 per
share). The underwriters did not receive any discount or commission related to
this transaction. The closing of the concurrent placement was contingent upon
the closing of About.com's initial public offering. ("IPO").

    On March 24, 1999, About.com completed its IPO which resulted in the
issuance of 3,450,000 shares of common stock at $25.00 per share (which included
450,000 shares in connection with the exercise of the underwriters'
over-allotment option) and the concurrent placement of 107,527 shares to Comcast
at $23.25 per share. In addition, upon the closing of the IPO, 3,346,715,
6,597,596 and 7,301,811 shares of Series A, B and C convertible preferred stock,
respectively, automatically converted into 6,139,640 shares of common stock and
$341,300 in unsecured promissory notes payable was forgiven. Net proceeds from
the offering and concurrent placement, after underwriting fees of $6.0 million
and offering costs of $1.7 million were approximately $81.0 million.

    (B) UNAUDITED INTERIM CONSOLIDATED FINANCIAL INFORMATION

    The interim consolidated financial statements of About.com as of June 30,
1999 and for the six months ended June 30, 1998 and 1999, included herein have
been prepared by the Company, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission ("SEC"). Certain
information and note disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the SEC's rules and regulations relating to
interim financial statements.

    In the opinion of management, the accompanying unaudited interim
consolidated financial statements reflect all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the financial position
as of June 30, 1999, and the results of operations and cash flows for the six

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                  DECEMBER 31, 1997 AND 1998 AND JUNE 30, 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)

(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
months ended June 30, 1998 and 1999. The results of operations for any interim
period are not necessarily indicative of About.com's results of operations for
any future interim period or for a full year.

    About.com's financial statements as of and for the six months ended June 30,
1999 include the consolidated accounts of About.com and its wholly-owned
subsidiary, VantageNet, Inc. from June 14, 1999 (date of acquisition) (see note
7). All significant intercompany transactions and balances have been eliminated
in consolidation.

    About.com has made certain reclassifications within its financial statements
to more accurately present the financial results of the Company. Accordingly,
certain prior period balances have been reclassified to conform to the current
period presentation.

    (C) USE OF ESTIMATES

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

    (D) CASH AND CASH EQUIVALENTS

    About.com considers all highly liquid securities with original maturities of
three months or less to be cash equivalents, which principally consist of money
market accounts.

    (E) PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is computed using the straight-line method over three
years, which is the estimated useful life of the related assets. Leasehold
improvements are amortized over their estimated useful lives, or the term of the
related lease, whichever is shorter. Equipment under capital leases is stated at
the present value of minimum lease payments and is amortized using the
straight-line method over the shorter of the lease term or the estimated useful
life of the assets.

    (F) GOODWILL

    Goodwill and other purchased intangible assets are stated net of accumulated
amortization of $33,700 at June 30, 1999. Goodwill and other purchased
intangible assets are being amortized on a straight-line basis over the expected
period of benefit of three years.

    (G) OTHER ASSETS

    Other assets include security deposits and costs incurred in connection with
the purchase of URL names. URL costs in the amount of $487,600 have been
capitalized and are being amortized over a 5-year period. As of June 30, 1999,
URL costs net of amortization amounted to $475,400.

                  DECEMBER 31, 1997 AND 1998 AND JUNE 30, 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)

(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (H) DEBT ISSUANCE COSTS

    Amortization of debt issuance costs is calculated on the straight-line
method over the life of the related debt instrument.

    (I) DEFERRED OFFERING COSTS

    Deferred offering costs at December 31, 1998 represented costs incurred in
connection with About.com's initial public offering. These costs were charged
against additional paid-in capital at the close of About.com's initial public
offering on March 24, 1999.

    (J) IMPAIRMENT OF LONG-LIVED ASSETS

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

    (K) INCOME TAXES

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

    (L) REVENUE AND EXPENSE RECOGNITION

    REVENUE RECOGNITION

    To date, substantially all of About.com's revenues have been derived from
the sale of advertisements on ABOUT.COM. About.com offers numerous sizes and
types of advertising placement, including banner advertisements, button
advertisements, text links and sponsorship programs. Advertising revenues are
derived principally from short-term advertising contracts in which About.com
typically guarantees a minimum number of impressions to advertisers over a
specified period of time for a fixed fee. Revenues from advertising sales are
recognized ratably in the period in which the advertisement is displayed,
provided that no significant About.com obligations remain, at the lesser of the
ratio of impressions delivered over total guaranteed impressions or the
straight-line basis over the term of the contract, and collection of the
resulting receivable is probable. Payments received from advertisers prior to
displaying their advertisements on ABOUT.COM are recorded as deferred revenue
and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                  DECEMBER 31, 1997 AND 1998 AND JUNE 30, 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)

(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
are recognized as revenue ratably as the advertisements are displayed. Pursuant
to its agreements with advertisers, About.com generally guarantees a minimum
number of impressions (times that an advertisement appears in pages viewed by
the users of ABOUT.COM) to be delivered over a specified period of time for a
fixed fee. To the extent minimum guaranteed impression levels are not met
ratably over the contract period, About.com defers recognition of the
corresponding pro-rata portion of the revenues relating to such unfulfilled
obligations until the guaranteed impression levels are achieved. When there is
no guarantee of a minimum number of impressions over a specified period of time,
About.com recognizes revenues in the period in which the advertisement is
displayed. About.com's short-term advertising agreements are generally
terminable by either party upon relatively short notice. In certain cases, these
agreements are longer in duration and entitle About.com to a share of revenues
generated by sales over a particular threshold resulting from direct links from
ABOUT.COM. To date, About.com has not recognized any revenues from these revenue
sharing agreements. About.com's revenue derived from these revenue sharing
agreements will be recognized by About.com upon notification from its
advertisers and electronic commerce partners of sales attributable to ABOUT.COM.

    A portion of About.com's revenues are from barter advertisements (agreements
whereby About.com trades advertisements on ABOUT.COM in exchange for
advertisements on third-party web sites). Barter advertising revenues and
expenses are recorded at the fair market value of services provided or received,
whichever is more determinable in the circumstances. Revenue from barter
advertising transactions is recognized as income when advertisements are
delivered on ABOUT.COM. Barter expense is recognized when About.com's
advertisements are run on third-party web sites, which is typically in the same
period when barter revenue is recognized. Barter expense is included as a
component of cost of revenues. Barter advertising revenues and expenses were $0,
$72,500 and $365,700 for the period from June 27, 1996 (inception) through
December 31, 1996 and for the years ended December 31, 1997 and 1998,
respectively. Barter advertising revenues and expenses for the six months ended
June 30, 1998 and 1999 were $49,200 and $452,000, respectively.

    A portion of About.com's revenues are from production and development fees.
Production and development fees represent HTML design services, graphic
services, engineering and database development and related services. About.com
charges clients for these services on either a fixed price or time and materials
basis. Revenue is recognized as these services are performed. These revenues
fluctuate based on the number of new programs initiated, types of services and
scope and complexity of each program. These revenues accounted for 2% of
revenues for the six months ended June 30, 1999.

    At December 31, 1998 and June 30, 1999, accounts receivable included
approximately $417,300 and $1,420,900 of unbilled receivables of which
$1,301,600 has been subsequently billed. Such unbilled receivables represent the
recognized sales value of short-term advertising contracts that were earned but
not billable to customers. The terms of the related advertising contracts
typically require billing at the end of 30, 60 or 90 days from the signing of
the contract.

    EXPENSE RECOGNITION--GUIDE COMPENSATION

    About.com's guides are compensated at an amount equal to the greater of a
monthly minimum guarantee or a percentage of net advertising revenues generated
by the entire network, which is

distributed among the guides based on the user traffic on their respective
sites. Net advertising revenues has been defined as total advertising revenues
received less particular types of non-cash revenues, third-party advertising
sales representative organization fees and marketing expenses. Guides are
currently entitled to a percentage of net transaction revenues and net
syndication revenues. In addition, management may distribute a semi-annual
discretionary bonus to guides. Guide compensation is included as a component of
cost of revenues, except for the non-cash compensation portion which was
recorded in connection with the grant of stock options to the guides and
presented as a separate line item above the gross profit (loss) line.

    EXPENSE RECOGNITION--DISTRIBUTION AND SYNDICATION PARTNERSHIPS

    About.com has entered into distribution and syndication partnership
agreements that drive traffic to ABOUT.COM. Through these partnerships,
About.com provides content to a partner's web site, and users can link to
ABOUT.COM by clicking on the content. About.com has agreements to provide
content to some of the leading Internet service providers, content web sites,
search engines/Internet directories and broadband cable-related sites. These
short-term agreements typically require About.com to make payments, which are
expensed, that are either fixed or are based on the amount of user traffic
directed from the partner's site to ABOUT.COM. About.com's fixed fees are paid
on a monthly basis and contracts in which fees are paid in advance are deferred
and amortized over the contract term.

    (M) PRODUCT DEVELOPMENT EXPENSES

    Product development expenses include personnel and consulting costs
associated with the design, development and testing of ABOUT.COM and About.com's
systems and editorial personnel costs. About.com generally expenses its product
development expenses as incurred. Software development costs are required to be
capitalized when a product's technological feasibility has been established by
completion of a working model of the product. To date, completion of a working
model of About.com's service and general release have substantially coincided.
As a result, About.com has not capitalized any software development costs since
those costs have not been significant.

    (N) ADVERTISING EXPENSES

    About.com expenses the costs of advertising its service as incurred. These
costs amounted to $60,000, $510,900, $5,262,800, $950,000 and $18,958,000 for
the period from June 27, 1996 (inception) through December 31, 1996, the years
ended December 31, 1997 and 1998 and the six months ended June 30, 1998 and
1999, respectively, and are included in sales and marketing in About.com's
statements of operations.

    (O) STOCK-BASED COMPENSATION

    About.com accounts for its employee stock option plans in accordance with
the provisions of Accounting Principles Board ("APB") Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations.
Compensation expense related to employee stock options is recorded only if, on
the date of grant, the fair value of the underlying stock exceeds the exercise
price. About.com

adopted the disclosure-only requirements of Statement of Financial Accounting
Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," which
allows entities to continue to apply the provisions of APB Opinion No. 25 for
transactions with employees and provide pro forma net income and pro forma
earnings per share disclosures for employee stock as if the fair-value-based
method of accounting in SFAS No. 123 had been applied to these transactions.

    About.com accounts for non-employee stock-based awards in which goods or
services are the consideration received for the equity instruments issued based
on the fair value of the consideration received or the fair value of the equity
instrument issued, whichever is more reliably measured.

    (P) BASIC AND DILUTED NET LOSS PER COMMON SHARE

    About.com adopted SFAS No. 128, "Computation of Earnings Per Share," during
the year ended December 31, 1997. In accordance with SFAS No. 128 and the SEC
Staff Accounting Bulletin No. 98, 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 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, all options,
warrants or other potentially dilutive instruments issued for nominal
consideration, prior to the anticipated effective date of an initial public
offering (including the 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. As a result, About.com has included 218,890 shares of common
stock in the calculation of basic and diluted net loss per common share for the
1996, 1997 and 1998 periods presented which relate to certain investor warrants
issued for nominal consideration, all of which were exercised in December 1998
when About.com exercised its right to call those warrants (see notes 9 and 11).

    Diluted net loss per common share for the period from June 27, 1996
(inception) through December 31, 1996 and the years ended December 31, 1997 and
1998 does not include the effects of options to purchase 0, 818,638, and
1,178,436 shares of common stock, respectively, 0, 427,003, and 68,708 common
stock warrants, respectively, or 0, 0 and 6,139,640 shares of convertible
preferred stock on an "as if" converted basis, respectively, as the effect of
their inclusion is anti-dilutive during each period. Diluted net loss per share
for the six months ended June 30, 1998 and 1999 does not include the effect of
options to purchase 935,243 and 2,821,811 shares of common stock and 729,376 and
65,860 warrants to purchase common stock, respectively.

    (Q) STOCK SPLIT

    In August 1996, About.com authorized and implemented a 1-for-40,000 common
stock split. Accordingly, all share and per share information in the
accompanying financial statements has been retroactively restated to reflect the
effect of the stock split.

    All common share and per share amounts in the accompanying financial
statements have been adjusted retroactively for a 1.00-for-2.809 reverse stock
split of About.com's common stock which was approved by the Board of Directors
and stockholders and effected on March 19, 1999.

    (R) RECENT ACCOUNTING PRONOUNCEMENTS

    As of January 1, 1998, About.com adopted the provisions of SFAS No. 130,
"Reporting Comprehensive Income", which establishes standards for reporting and
displaying comprehensive income and its components in a full set of general
purpose financial statements. The adoption of this standard has had no impact on
About.com's financial statements. Accordingly, About.com's comprehensive net
loss is equal to its net loss for all periods presented.

    In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information", which 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. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. SFAS No. 131 is
effective for fiscal years beginning after December 15, 1997. In the initial
year of application, comparative information for earlier years must be restated.
About.com has determined that it does not have any separately reportable
business segments.

    In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"), which provides guidance
for determining whether computer software is internal-use software and on
accounting for the proceeds of computer software originally developed or
obtained for internal use and then subsequently sold to the public. It also
provides guidance on capitalization of the costs incurred for computer software
developed or obtained for internal use. About.com adopted SOP 98-1 in 1999 and
there has not been any material effect on the financial statements.

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which establishes accounting and reporting
standards for derivative instruments, including derivative instruments embedded
in other contracts, and for hedging activities. SFAS No. 133 is effective for
all fiscal quarters of fiscal years beginning after June 15, 2000. This
statement is not expected to affect About.com as About.com currently does not
engage or plan to engage in derivative instruments or hedging activities.

(3)  BUSINESS AND CREDIT CONCENTRATIONS

    Financial instruments which subject About.com to concentrations of credit
risk consist primarily of cash and cash equivalents, accounts receivable,
accounts payable and accrued liabilities. The carrying amounts of these
instruments approximate fair value. The carrying amount of About.com's capital
leases and other equipment financing obligations approximates the fair value of
these instruments based upon management's best estimate of interest rates which
are similar to the rates obtained in its January and February 1999 lease line of
credit (see note 13).

(3)  BUSINESS AND CREDIT CONCENTRATIONS (CONTINUED)
    About.com maintains cash and cash equivalents with a domestic financial
institution. About.com performs periodic evaluations of the relative credit
standing of this institution. From time to time, About.com's cash balances with
this financial institution may exceed Federal Deposit Insurance Corporation
insurance limits.

    About.com's customers are concentrated in the United States. About.com
performs ongoing credit evaluations, generally does not require collateral and
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of each customer, historical trends and other information; to
date, such amounts have been within management's expectations.

    For the period from June 27, 1996 (inception) to December 31, 1996, there
were no customers that accounted for over 10% of total revenues generated by
About.com, or of gross accounts receivable at December 31, 1996.

    For the year ended December 31, 1997, one customer accounted for
approximately 19% of total revenues generated by About.com. No customers
accounted for over 10% of gross accounts receivable at December 31, 1997. As of
December 31, 1997, About.com had receivables in excess of $10,000 from three
separate customers totaling approximately $43,000.

    For the year ended December 31, 1998, one customer accounted for
approximately 12% of total revenues generated by About.com. This advertising
arrangement ended on December 31, 1998. For the year ended December 31, 1998, a
third-party Internet advertising sales representative organization accounted for
approximately 21% of About.com's total revenues and accounted for approximately
35% of gross accounts receivable at December 31, 1998, totaling approximately
$376,000.

    For the six months ended June 30, 1998, there was one customer and a
third-party Internet advertising sales representative organization accounted for
approximately 14% and 15%, respectively, of revenue generated by About.com. For
the six months ended June 30, 1999, no customer accounted for more than 10% of
revenue or gross receivables for the period then ended.

    In June 1997, About.com entered into a consulting agreement with a major
financial institution pursuant to which About.com agreed to provide consulting
assistance in connection with the development of a customized web site for an
aggregate amount of $450,000. Fees in connection with this agreement have been
recognized as performance occurred under the terms of the agreement, net of any
expenses, and have been recorded as other income for the year ended December 31,
1997. In connection with this agreement, About.com issued the financial
institution a warrant to purchase 35,600 shares of common stock at $14.05 per
share with an expiration date of December 31, 1999. The fair value of the
warrants, using the Black-Scholes model based upon the following assumptions:
risk-free interest rate of 6%; dividend yield of 0%; expected life of 2.5 years;
and volatility of 0%, was deemed insignificant on the date of grant.

(5)  INCOME TAXES

    No provision for US federal or state income taxes has been recorded for any
period as About.com has incurred operating losses since inception.

    Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
About.com's deferred tax assets for federal and state income taxes are as

not more likely than not that these assets will be realized. No income tax
benefit has been recorded for all periods presented because of the valuation
allowance.

    During the period from June 27, 1996 (inception) to December 31, 1996 and
the years ended December 31, 1997 and 1998, the valuation allowance for the
deferred tax assets increased by $1,121,000, $3,967,000, and $7,159,000,
respectively.

    As of December 31, 1997 and 1998, About.com had net operating loss
carryforwards for federal income tax purposes of approximately $10.6 million and
$26.3 million, respectively. There can be no assurance that About.com will
realize the benefit of the net operating loss carryforwards. The federal net
operating loss carryforwards are available to offset future taxable income and
expire at various dates beginning in fiscal year 2011 through 2013 if not
utilized.

    Due to the "change in ownership" provisions of the Internal Revenue Code,
the availability of About.com's net operating loss and credit carryforwards may
be subject to an annual limitation against taxable income in future periods,
which could substantially limit the eventual utilization of these carryforwards.

(6)  RELATED-PARTY TRANSACTIONS

    At December 31, 1997, Mr. Scott P. Kurnit, About.com's President and Chief
Executive Officer and Chairman of the Board of Directors, elected to defer
compensation in the amount of $414,700, for accrued but unpaid salary and
bonuses. In January 1998, Mr. Kurnit converted $300,000 of that amount into a
convertible note payable (see note 9). During 1998, Mr. Kurnit elected to defer
an additional $67,000 of compensation, which at December 31, 1998 totaled
$181,700.

    On April 20, 1998, About.com and a director of an investor in About.com
executed an advisory agreement, pursuant to which the individual agreed to
provide consulting and advisory services to About.com including, but not limited
to, introducing About.com to members of the investment community and assisting
About.com with respect to financial and strategic matters. In consideration for
his services under the advisory agreement, the individual was issued a warrant
to purchase up to an aggregate of 21,360 shares of About.com's common stock, at
an exercise price of $5.06 per share. The warrant is exercisable at any time
during the 10-year period commencing on the date of the closing of a qualified
initial public offering (which would include the IPO). The fair value of the
warrants, using the Black-Scholes model and the following assumptions: risk-free
interest rate of 6%, dividend yield of 0%, expected life of ten years, and
volatility of 0%, resulted in a compensation charge of $36,000 during 1998.
These warrants had not been exercised as of June 30, 1999.

(7)  ACQUISITION

    On June 14, 1999, About.com formed About.com Acquisition Corp. ("AAC"), a
Delaware corporation and a wholly-owned subsidiary of About.com. AAC was merged
with and into VantageNet, Inc., a Minnesota corporation ("VantageNet"), with
VantageNet as the surviving corporation. The merger was effected pursuant to the
Agreement and Plan of Reorganization, dated June 14, 1999, by and among
About.com, AAC, VantageNet and certain stockholders thereof. As a result of the

became a wholly-owned subsidiary of About.com. VantageNet is an Internet
marketing company which utilizes electronic surveys and/or polling tools.

    The consideration paid by About.com in connection with the merger consisted
of $550,000 in cash and 65,550 newly issued shares of common stock, par value
$0.001, of About.com. The total purchase price for this transaction was
approximately $2.5 million. The difference between the fair market value of
VantageNet's net tangible assets and the purchase price has been accounted for
as goodwill and other purchased intangible assets and is being amortized over
the expected period of benefit of three years.

(1) The Company computes net loss per share in accordance with provisions of FAS
    No. 128, "Earnings Per Share". Basic net loss per share is computed by
    dividing the net loss for the period by the weighted average number of
    common shares outstanding during the period. The weighted average common
    shares used to compute pro forma basic net loss per share includes the
    actual weighted average common shares outstanding for the historical year
    ended Decemer 31, 1998 and the six month periods ended June 30, 1998 and
    1999, respectively, plus the common shares issued in connection with the
    acquisition of VantageNet from January 1, 1998. The common stock issued in
    connection with the acquisition of VantageNet was 65,550 shares, which was
    adjusted for the weighted average period such shares were considered to be
    outstanding during 1999. In addition, diluted net loss per share is equal to
    basic net loss per share as common stock issuable upon exercise of the
    Company's employee stock options and upon exercise of outstanding warrants
    are not included because they are antidilutive. In future periods, the
    weighted average shares used to compute diluted earnings per share will
    include the incremental shares of common stock relating to outstanding
    options and warrants to the extent such incremental shares are dilutive.

    On October 17, 1996, About.com executed a secured 8.25% Promissory Note
("8.25% Note") in the original principal amount of $3,905,600. On August 27,
1997, the 8.25% Note was amended to, among other things, reduce the principal
amount outstanding thereunder to $3,255,600, reflecting a reduction of $650,000
which was converted into a convertible note payable. In connection with the
execution of the convertible note payable (see note 9), About.com issued
warrants to purchase 24,105 shares of About.com's common stock at an exercise
price of $4.21 per share. The fair value of the warrants, using a Black-Scholes
model and the following assumptions: risk-free interest rate of 5.7%, dividend
yield of 0%, expected life of ten years and volatility of 0%, was deemed
insignificant on the date of grant.

    On April 23, 1998, the 8.25% Note was amended again to, among other things,
(i) reduce the principal amount outstanding thereunder to $1,555,600, reflecting
a reduction of $1,700,000 which was simultaneously converted into 944,444 shares
of Series B convertible preferred stock ("Series B Preferred") (see notes 9 and
10), (ii) reduce the interest amount outstanding thereunder by $305,800, which
was simultaneously converted into 169,883 shares of Series B Preferred, and
(iii) provide that the remaining principal and interest would automatically
convert into shares of About.com's Series C convertible preferred stock ("Series
C Preferred") upon the closing of the next financing conducted by About.com if
the next sale of equity to new investors on or prior to March 31, 1999 was at a

share less than $3.00 per share (on a pre-split basis), otherwise the note was
due and payable on March 31, 1999. On November 13, 1998, About.com issued
913,856 shares of About.com's Series C Preferred at $1.95 per preferred share in
consideration for the cancellation of the remaining $1,555,600 of principal and
$226,400 of interest outstanding under the 8.25% Note. Upon the closing of the
IPO, these 913,856 shares of About.com's Series C Preferred converted into
325,333 shares of common stock.

    In January, June and July 1998, About.com issued to the holder of the 8.25%
Note warrants to purchase an additional 2,670, 2,111 and 4,119 shares of
About.com's common stock at an exercise price of $4.21 per share in
consideration for entering into a subordination agreement with another creditor
of About.com. The value attributed to the warrants, using a Black-Scholes
pricing model and the following assumptions: risk-free interest rate of 6.0%,
dividend yield of 0%, expected life of ten years and volatility of 0%, was
$18,000 in the aggregate, based upon the respective grant dates, which was
recorded as additional interest expense in 1998.

    NOTES PAYABLE--CREDIT FACILITY

    During January 1998, About.com entered into an asset backed credit facility
with Phoenix Leasing Incorporated ("Phoenix") which was funded as About.com
pledged fixed assets as security to Phoenix. During the year ended December 31,
1998, About.com received a total loan of $507,700 and pledged $507,700 of fixed
assets as security. The effective interest rate of the credit facility is 18%.
As of December 31, 1998, the balance outstanding was $437,500 of which $154,000
is due in 1999, $157,000 in 2000 and $126,500 in 2001. As of June 30, 1999, the
balance outstanding was $365,600 of which $143,600 is due within the next twelve
months.

    Between March 27, 1997 and January 15, 1998, About.com issued several
secured subordinated notes, which converted into Series A Notes ("Series A
Notes"), for an aggregate principal amount of $4,950,000, which amount included
(i) the conversion of $650,000 from the 8.25% Notes and (ii) the conversion of
$300,000 of deferred compensation owed to Mr. Kurnit. These notes bore interest
at a variable rate equal to the prime rate plus two percent per annum. At
December 31, 1997, prime rate plus 2% was 10.5%. Pursuant to their terms, the
principal due on the Series A Notes were automatically convertible into shares
of About.com's common stock or convertible preferred stock upon the closing of
the next equity financing conducted by About.com. The conversion price for these
notes, as provided for in the original note agreement, was $1.50 per preferred
share.

    In connection with the issuance of this debt, About.com issued warrants to
purchase 218,890 shares of About.com's common stock at an exercise price of
$0.03 per share and 90,858 shares of About.com's common shares at an exercise
price of $4.21 per share (which includes warrants to purchase 24,105 shares
relating to the conversion of $650,000 from the 8.25% Notes), all of which
expire ten years from their date of issuance; provided that, under certain
circumstances, About.com could cancel the warrants after providing the holders
thereof a reasonable period of time to exercise the warrants prior to their
cancellation. The value attributed to the warrants was $106,000 for warrants
issued with an exercise price of $0.03 and $31,000 for warrants issued with an
exercise price of $4.21 per share. These values were estimated, using a
Black-Scholes pricing model, based on the following assumptions: risk-free

interest rate of 6.0%, dividend yield of 0%, expected life of 10 years and
volatility of 0%. These amounts were recorded as an original issue debt discount
and amortized to interest expense over the life of the loans. In December 1998,
About.com exercised its right to call certain investor warrants which resulted
in the issuance of 218,890 shares of common stock at $0.03 per share and 66,753
shares of common stock at $4.21 per share for net cash proceeds of approximately
$287,600. The remaining 24,105 warrants with an exercise price of $4.21 per
share were cancelled.

    On April 23, 1998, About.com issued an aggregate of 3,346,715 shares of
Series A Preferred, at a purchase price of $1.50 per preferred share, to holders
of the Series A Notes, in consideration for the cancellation of all principal
owed under the Series A Notes and $70,000 of interest accrued under the Series A
Notes prior to August 12, 1997. All remaining interest under the Series A Notes
up through April 23, 1998 was evidenced by newly issued unsecured promissory
notes of About.com which amounted to $337,100 as of December 31, 1998. The notes
bore interest at 6% and had no due date. In accordance with the terms of the
note upon the closing of a qualified initial public offering (including the
IPO), all amounts due under these unsecured promissory notes were automatically,
by its original terms, forgiven and canceled. Accordingly, such amount has been
recorded as a contribution to additional paid-in capital upon the closing of the
IPO.

    Between November 1997 and February 1998, About.com issued several secured
subordinated notes ("Series B Notes") for an aggregate principal amount of
$2,800,000, of which $1,000,000 bore interest at a variable rate equal to the
prime rate plus two percent per annum and $1,800,000 bore interest at 10%
percent per annum and were due on demand. At December 31, 1997, prime rate plus
2% was 10.5%. Pursuant to their terms, the Series B Notes were automatically
convertible into shares of About.com's Series B Preferred upon the closing of
the next equity financing conducted by About.com. The conversion price for these
notes, as provided for in the original note agreement, was $1.80 per preferred
share.

    In connection with the issuance of this debt, About.com issued warrants to
purchase 250,192 shares of About.com's common stock at an exercise price of
$5.06 per share, all of which expire ten years from their date of issuance;
provided that, under certain circumstances, About.com may cancel the warrants
after providing the holders thereof a reasonable period of time to exercise the
warrants prior to their cancellation. The fair value of the warrants, using the
Black-Scholes model and the following assumptions: risk-free interest rate of
6.0%, dividend yield of 0%, expected life of 10 years and volatility of 0%, was
$150,000 and recorded as additional interest expense. In December 1998,
About.com exercised its right to call certain investor warrants which resulted
in the issuance of 250,192 shares of common stock at $5.06 per share for net
cash proceeds of approximately $1,266,000.

    On April 23, 1998, About.com issued 1,594,380 shares of Series B Preferred,
at a purchase price of $1.80 per share, to holders of the Series B Notes, in
consideration for the cancellation of all indebtedness of About.com under the
Series B Notes. Upon the closing of the IPO, these 1,594,380 shares of Series B
preferred converted into 567,601 shares of common stock.

    COMMON STOCK

    During 1996, About.com issued shares of common stock to its founders and
original employees at approximately $0.03 per share. About.com's right to
repurchase these shares in certain circumstances was to lapse over a period of
three years. During 1997, About.com's Board of Directors approved a resolution
to cancel these shares in exchange for incentive stock options. Accordingly, on
March 20, 1997, About.com canceled 367,802 common shares and exchanged these
shares on a one-for-one basis for participation in the 1997 Employee Stock
Incentive Plan. These incentive stock options were granted with an exercise
price equal to their fair market value, or $0.51 per share, at the date of grant
as determined by an independent valuation.

(12)  STOCK OPTION PLAN (CONTINUED)
    The weighted-average remaining life of the 1,128,649 options outstanding at
December 31, 1998 is 8.75 years.

    For the twelve months ended December 31, 1998, About.com recorded deferred
compensation expense of approximately $1,716,900, in connection with the grant
of certain options to employees and directors, representing the difference
between the deemed fair value of About.com's common stock at the date of grant
for accounting purposes and the exercise price of the related options. This
amount is presented as a reduction of stockholders equity (deficit) and
amortized over the vesting period, typically four years, of the applicable
options. About.com granted approximately 485,921 options at a weighted average
exercise price of $1.43 per share; all of which were granted at less than the
deemed fair value at the date of grant. About.com has amortized $478,000 of
deferred compensation for the year ended December 31, 1998 of which $27,000 has
been included in cost of revenues. About.com has amortized $278,100 of deferred
compensation for the six months ended June 30, 1999, which $9,400 has been
included in cost of revenue. About.com expects to amortize the following amounts
of deferred compensation annually: 1999--$423,900; 2000--$291,400;
2001--$291,400; and 2002--$232,200.

    In September 1997, About.com recorded compensation expense of approximately
$3,300 in connection with options granted outside of the Plan to consultants to
purchase 49,787 shares of common stock at an exercise price of $0.51 per share.
The fair value of the options was determined using the Black-Scholes model and
the following assumptions: risk-free interest rate of 5.7%, dividend yield of
0%, expected life of 10 years and volatility of 0%. None of these options had
been exercised as of June 30, 1999.

    About.com also recorded compensation expense of approximately $23,000 in
connection with options granted to consultants under the Plan in December 1998
to purchase 5,340 shares of common stock at an exercise price of $4.21 per
share. The fair value of the options was determined using the Black-Scholes
model and the following assumptions: risk-free interest rate of 6.0%, dividend
yield of 0%, and volatility of 0%. During the six months period ended June 30,
1999, 4,005 of these options have been exercised.

    In March 1999, About.com recorded a non-cash charge of $3.6 million for
guide compensation. About.com has granted full vested, non-qualified stock
options to purchase 199,500 shares of common stock at an exercise price of
$25.00 per share to substantial majority of its guides. The options have a two
year term. Accordingly, such amount was recorded as a non-cash compensation
expense in About.com's statement of operations for the six months ended June 30,
1999 with an offsetting increase in additional paid-in capital. During the six
months ended June 30, 1999, 250 options were exercised.

    Had About.com determined compensation expense based on the fair value on the
grant date for its stock options issued to employees under SFAS No. 123,
About.com's net loss would have been adjusted to the pro forma amounts indicated
below:

</TABLE>

    The per share weighted-average fair value of stock options granted during
1997 and 1998 was $0.09 and $3.87, respectively, on the date of grant using the
Black Scholes option pricing model with the following weighted-average
assumptions for 1997 and 1998: (i) risk-free interest rate--5.7% and 6%
respectively; (ii) dividend yield--0.0% for both years; and (iii) expected
life--3.4 and 4.4 years, respectively. As permitted under the provisions of SFAS
No. 123, and based on the historical lack of a public market for About.com's
options, no factor for volatility has been reflected in the option pricing
calculation.

    The Company's Employee Stock Purchase Plan ("ESPP") was adopted by the Board
of Directors in February 1999. The ESPP will provide eligible employees of the
Company the opportunity to apply a portion of their compensation to the purchase
of shares of the Company at a 15% discount. The Company has reserved 125,000
authorized but unissued shares of common stock for issuance under the ESPP.

(13)  COMMITMENTS AND CONTINGENCIES

    (A) LEASES

    About.com leases certain facilities in New York and White Plains
(Westchester County) and equipment under non-cancelable operating leases. These
leases generally provide for rental increases at specified intervals. In
addition, About.com is a lessee, under several capital lease agreements with
third parties for certain equipment. Total rent expense for the years ended
December 31, 1997 and December 31, 1998 was $320,900 and $320,600, respectively.

    In March and September 1999, About.com entered into two lease agreements to
expand its office space in New York. These leases expire on April 30, 2003 and
August 31, 2000, respectively. The minimum lease payments under these leases
amount to approximately $2.7 million and have been included above as part of the
minimum lease payment schedule.

    In January and February 1999, About.com entered into a lease line of credit
for $781,300 to finance capital equipment, of which $232,200 is due in 1999,
$268,800 in 2000, $273,300 in 2001, and $7,000 in 2002. The effective interest
rate of the credit facility was 16%. As of June 30, 1999, the balance
outstanding was $686,900, of which $242,000 is due within the next twelve
months.

    (B) EMPLOYMENT AGREEMENTS

    At December 31, 1998, About.com had employment agreements with two senior
employees which provide for severance benefits, among other items. In the event
these agreements are terminated, About.com may be liable for severance up to
$420,000 payable during the year following that termination.

    During January 1999, About.com entered into employment arrangements with two
employees. The employment arrangements provide for minimum salary levels, and
incentive compensation and severance benefits, among other items. About.com
granted 133,500 options in the aggregate to the two employees. The exercise
price of the options is $4.21 per share. As a result, About.com recorded
deferred compensation expense in the first quarter of 1999 of $2,775,400
relating to the 133,500 options for the difference between the deemed fair value
of About.com's common stock (the initial public offering price of $25.00 per
share for accounting purposes) and the exercise price of that option at the date
of grant of $4.21 per share. This amount has been presented as a reduction of
stockholders' equity and is being amortized over the four-year vesting period of
the applicable options. About.com has amortized $346,900 of deferred
compensation for the six months ended June 30, 1999 and expects to amortize the
following amounts of deferred compensation annually: 1999--$693,800;
2000--$693,800; 2001--$693,800; and 2002--$694,000.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The registrant's Second Amended and Restated Certificate of Incorporation
(the "certificate") provides that, except to the extent prohibited by the
Delaware General Corporation Law, as amended (the "DGCL"), the registrant's
directors shall not be personally liable to the registrant or its stockholders
for monetary damages for any breach of fiduciary duty as directors of the
registrant. Under the DGCL, the directors have a fiduciary duty to the
registrant 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 registrant, 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 the 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
registrant has applied for 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 registrant may 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

                                      II-1
<PAGE>
(whether civil, criminal, administrative or investigative) by reason of the fact
that that person is or was a director or officer of the registrant, or is or was
serving at the request of the registrant 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 any threatened, pending or completed action, suit or proceeding.

    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 under the certificate. The registrant is not aware of any
threatened litigation or proceeding that may result in a claim for any
indemnification.

ITEM 17. UNDERTAKINGS

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
this indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
those liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by that
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of counsel the matter has
been settled by controlling precedent, submit to a court

                                      II-4
<PAGE>
of appropriate jurisdiction the question whether this indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of that issue.

    The undersigned registrant hereby undertakes that:

        (1)  For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424 (b)(1) or
    (4), or 497(h) under the Securities Act of 1933, 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 this offering of these securities at
    that time shall be deemed to be the initial BONA FIDE offering thereof.

                1999 NON-OFFICER STOCK OPTION/STOCK ISSUANCE PLAN


                                   ARTICLE ONE

                               GENERAL PROVISIONS


         I.        PURPOSE OF THE PLAN

                   This 1999 Non-Officer Stock Option/Stock Issuance Plan is
intended to promote the interests of About.com, Inc., a Delaware 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 two 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,
         and

                             (ii)      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).

                   B.   The provisions of Articles One and Four 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.   The Board shall have the authority to administer the
Plan but may delegate such authority to a Committee.

                   B.   The Plan Administrator shall 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;


<PAGE>


                             (ii)      to determine, with respect to awards made
         under the Plan, 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 and the maximum term for which the option is to remain
         outstanding;

                             (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 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 the Committee and reassume
all powers and authority previously delegated to such committee.

                   D.   Service on the Committee shall constitute service as a
Board member, and members of the Committee shall accordingly be entitled to full
indemnification and reimbursement as Board members for their service on the
Committee. No member of the 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 Plan are as
follows:

                             (i)       Employees (other than officers of the
         Corporation), and

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

         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 market. The maximum number of shares of Common
Stock reserved for issuance over the term of the Plan shall not exceed 400,000
shares.


                                       2

<PAGE>


                   B.   Shares of Common Stock subject to outstanding options
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, 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.

                   C.   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 and (ii) the number and/or class of securities and the
exercise price per share in effect under each outstanding option under the Plan.
Such adjustments to the outstanding options are to be effected in a manner 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.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM

         I.        OPTION TERMS

                   Each option shall be a Non-Statutory Option and 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.

                   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 Four and the documents evidencing the option, be payable:

                             (i)       in cash,

                             (ii)      check made payable to the Corporation

                             (iii)     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

                             (iv)      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.

                   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.


                                       4

<PAGE>

                   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

                             (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.


                                       5

<PAGE>


                   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. An 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 Optionee and/or 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.       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 for vested shares 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.


                                       6

<PAGE>


                   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 price payable per share under each outstanding option, PROVIDED the
aggregate exercise price payable for such securities shall remain the same and
(ii) the maximum number and/or class of securities available for issuance over
the remaining term of the Plan.

                   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.

                             STOCK ISSUANCE 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
Four, 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.


                                       8

<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.

<PAGE>


                   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 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.

         I.        NO IMPAIRMENT OF AUTHORITY

                   Outstanding awards shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

         II.       FINANCING

                   The Plan Administrator may permit any Optionee or Participant
to pay the option exercise price under the Discretionary Option Grant Program or
the purchase price of shares issued under the Stock Issuance Program by
delivering a full-recourse, interest bearing promissory note payable in one or
more installments. The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion. In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

         III.      TAX WITHHOLDING

                   The Corporation's obligation to deliver shares of Common
Stock upon the exercise of options or the issuance or vesting of such shares
under the Plan shall be subject to the satisfaction of all applicable Federal,
state and local income and employment tax withholding requirements.

         IV.       EFFECTIVE DATE AND TERM OF THE PLAN

                   The Plan shall terminate upon the EARLIEST of (i) August __,
2009, (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

                   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.

         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.
