Our Business

   We are a leading independent source of original, informative, timely and
trusted consumer-oriented health and wellness information, products and
services on the Web. Our website, onhealth.com, is a consumer-focused online
health destination dedicated to the management of personal and family health
and well-being. We employ ten full-time staff editors and writers and we use
over 100 health and medical writers and contributors, enabling us to update our
website daily with original health-related features. By providing users with a
broad range of original in-depth reporting, substantive resources and
references, community discussions, direct access to experts, interactive tools
and exclusive search capabilities, onhealth.com combines the strength of
credible journalism with the power of online interactivity.

   We launched our website in July 1998. During July 1999, according to Media
Metrix, onhealth.com had nearly 1,200,000 unique users, an increase of 182%
from March 1999, which ranks the website as one of the most trafficked consumer
health content websites in July 1999. In addition, in June 1999 onhealth.com
attracted 1,563,785 visits, an increase of 61% from our March 1999 visits,
according to Internet Profile Corporation. We have launched a coordinated
traditional media advertising and public relations campaign designed to build
our brand through the use of television, radio, outdoor, print and online
media. We also distribute in excess of 60,000 daily and weekly broadcast e-
mails to registered users who have requested our Daily Briefing, Weekly
Newsletter and Health Info Tracker. This private and personalized e-mail allows
our users to stay current on the health-related subjects most important to
themselves and their families. To date, we have developed distribution
partnerships and content sharing relationships resulting in over 950 websites
that drive traffic to our website. We intend to aggressively expand our content
and distribution partnerships with both online and traditional media partners
that can direct additional users to our website.

   Because we are not aligned or affiliated with any one individual,
institution or medical organization, we are able to provide an independent
voice and serve as a trusted consumer advocate for health-related issues. We
believe this will allow us to build a loyal and dedicated audience that will
fuel multiple revenue opportunities. While we believe the demographics of our
users are highly attractive to advertisers, we are developing our website to
generate revenue opportunities from multiple sources, including
advertising/sponsorships, e-commerce transactions and content syndication. We
have a shopping area on our website designed to offer our users a wide variety
of health and wellness products including prescription and over-the-counter
drugs, vitamins, herbs, books, magazines, foods, home products and gifts.

Our Market Opportunity

   According to Cyber Dialogue, an industry research firm, during 1998,
approximately 22 million adults in the United States searched online for health
and medical information. Cyber Dialogue estimates that approximately 70% of the
persons searching for health and medical information online

                                       1
<PAGE>

believe the Internet empowers them by providing them with information before
and after they go to a doctor's office. Cyber Dialogue also estimates that in
the year 2000, the number of adults in the United States searching for online
health and medical information will grow to approximately 33 million. In
addition, the Internet is enabling advertisers and online merchants to
inexpensively reach vast, yet highly targeted audiences, and to measure in
real-time the effectiveness of their programs.

   The quality and breadth of health oriented websites varies widely and to
date no clear brand has emerged as the leading provider of trusted consumer-
oriented health and wellness information on the Internet. Most of these
websites do little more than repurpose and repackage non-proprietary content
without tailoring such content for the consumer and providing context, insight
or analysis. Many offer little disclosure about their affiliations, the sources
of their information and potential conflicts of interest. Additionally, many
health websites are poorly designed, difficult to navigate and do not
understand the needs of women as the principle gatekeepers of the healthcare
dollar. Accordingly, we believe there is a substantial and growing unmet need
for a well-known, trusted, comprehensive health-related website that addresses
consumers' health needs accurately and intelligently while providing a
satisfying consumer experience. Moreover, we believe that such a website will
have the ability to generate significant revenue from a variety of sources,
including advertising and commerce.

Our Strategy

   Our goal is to become the premier source of consumer-oriented health and
wellness information and services on the Internet. We intend to achieve this
goal by implementing the following strategies:

  . leveraging and enhancing our expansive proprietary health content;

  . providing consumers with a compelling Internet health experience;

  . establishing onhealth.com as the premier brand for health and wellness
    information on the Internet;

  . capitalizing on revenue generating opportunities; and

  . engaging in selective acquisitions and strategic partnerships.

Our History

   Until January 1998, our traditional line of business had been the
development, production and distribution of medical CD-ROM titles. We also
supplied video, animation and graphic assets to a health and medical cable
television channel. In late 1997, our Board of Directors revised our business
strategy and brought in an entirely new management team and other key employees
skilled in the development of Internet websites, and in 1998, we focused on the
development of a consumer-oriented health and wellness website.

                                  Risk Factors
- --------------------------------------------------------------------------------

   You should carefully consider the risks and uncertainties described below,
as well as the other information included or incorporated by reference in this
prospectus and the accompanying prospectus supplement, before making an
investment decision. Our business, financial condition and operating results
could be adversely affected by any of the following factors, in which event the
trading price of our common stock could decline, and you could lose part or all
of your investment. The risks and uncertainties described below and in the
accompanying prospectus supplement are not the only ones that we face.
Additional risks and uncertainties not presently known to us, or that we
currently think are immaterial, may also impair our business operations.

Risks Related to Our Business

We have a history of losses and negative cash flow and anticipate continued
losses.

   Since our inception, we have incurred significant losses and negative cash
flow, and as of June 30, 1999, had an accumulated deficit of approximately
$100.7 million. We have not achieved profitability and expect to continue to
incur operating losses for the foreseeable future as we fund operating and
capital expenditures in areas such as expansion of our network, advertising,
brand promotion, content development, sales and marketing, and operating
infrastructure. Our business model assumes that consumers will be attracted to
and use healthcare information and related content available on our Internet-
based consumer healthcare network which will, in turn, allow us the opportunity
to sell advertising designed to reach those consumers. Our business model also
assumes that those consumers will access important healthcare needs through
electronic commerce using our website and that local healthcare organizations
will affiliate with us. This business model is not yet proven, and we cannot
assure you that we will ever achieve or sustain profitability or that our
operating losses will not increase in the future.

Since we recently changed our business focus, we essentially are a new company
and accordingly are subject to those risks associated with a new company.

   Even though we were founded in 1990, we have only been active online since
1996 and the onhealth.com website was not actually launched until July 1998. As
a result, our company is essentially a new venture. Therefore, we do not have a
significant operating history upon which you can evaluate us and our prospects,
and you should not rely upon our past performance to predict our future
performance. In transitioning to our new business model, we are substantially
changing our business operations, sales and implementation practices, customer
service and support operations and management focus. We are also facing new
risks and challenges, including a lack of meaningful historical financial data
upon which to plan future budgets, competition from a wider range of sources,
the need to develop strategic relationships and other risks described below. We
cannot guarantee that we will be able to successfully transition to our new
business model.

   Our ability to generate profits, if any, will depend on our ability to:

  . attract consumers to our website;

  . attract advertisers to our website;

  . generate e-commerce revenue from our website; and

  . control costs.

   We anticipate continued significant operating losses at least through 2000,
as our website is improved and marketed and the OnHealth network is enhanced.
We cannot assure you that we will ever attain profitability.


                                       4
<PAGE>

Our business model relies to a large extent on advertising revenue from our
website. We cannot provide any assurance that we will generate significant
advertising revenue.

   Our future is highly dependent on increased use of the Internet as an
advertising medium. We expect to derive a substantial amount of our revenue
from advertising and sponsorships. The Internet advertising market is new,
extremely competitive and rapidly evolving, and we cannot yet predict its
effectiveness as compared to traditional media advertising. As a result, demand
and market acceptance for Internet advertising solutions are uncertain. Most of
our current or potential advertising customers have little or no experience
advertising over the Internet and have allocated only a limited portion of
their advertising budgets to Internet advertising. 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. Such customers may find Internet advertising to be less effective for
promoting their products and services relative to traditional advertising
media. We cannot assure you that the market for Internet advertising will
continue to emerge or become sustainable. If the market for Internet
advertising fails to develop or develops more slowly than we expect, then our
ability to generate advertising revenue would be materially adversely affected.
To date, advertisers have not, by their actions, shown that they believe in the
Internet as a legitimate advertising medium.

   Advertising rates quoted by different vendors vary widely, making it
difficult for us to project future levels of advertising revenue. Internet
advertising rates are based in part on third-party estimates of an individual's
use of an Internet website. These estimates of use are called impressions. Such
estimates are often based on sampling techniques or other imprecise measures,
and may materially differ from our own estimates. We do not know if advertisers
will accept our or other parties' measurements of impressions. Since the
Internet advertising industry is in its infancy, universally accepted standards
measuring the effectiveness of a particular Internet advertisement have not
been established or widely embraced. Our advertising revenue could be adversely
affected if we are unable to adapt to new forms of Internet advertising.

   Moreover, filter software programs are available that limit or prevent
advertising from being delivered to an Internet user's computer. Widespread
adoption of this software could adversely affect the commercial viability of
Internet advertising and, therefore, our business.

In order to compete for advertising dollars with the growing number of Internet
websites, we must establish, maintain and strengthen our brand.

   In order to expand our audience of users and increase our online traffic, we
must establish, maintain and strengthen our brand. For us to be successful in
establishing our brand, we believe healthcare consumers must perceive us as a
trusted source of healthcare information, and advertisers and merchants must
perceive us as an effective marketing and sales channel for their products and
services. As discussed in this prospectus, we are increasing substantially our
marketing budget in our efforts to establish brand recognition and brand
loyalty. Our business could be materially adversely affected if our marketing
efforts are not productive or if we cannot strengthen our brand.

   In addition, to remain competitive with other Internet companies, including
the numerous other Internet health-related websites, we must continue to
enhance and improve the responsiveness, functionality and features of our
website and develop other products and services. This will require us to:

  . develop or license increasingly complex technology; and

  . create an easy to use and functional e-commerce component to our website.

   We may not succeed in developing or introducing such features, functions,
products and services in order to attract consumers. Such failure would
adversely affect our business, results of operations and financial condition.

                                       5
<PAGE>

Since our advertising contracts are for short terms and often guarantee a
minimum number of impressions, we cannot be sure that we will continue to
attract Internet advertisers.

   The majority of our advertising contracts have been for terms averaging
three months in length, with relatively few longer-term advertising contracts.
We cannot assure you that our current advertisers will continue to purchase
advertisements on our website. In addition, our advertising contracts typically
guarantee the advertiser a minimum number of impressions. To the extent that
minimum impression levels are not achieved for any reason, we may be required
to make good or provide additional impressions after the contract term.
Providing additional impressions may adversely affect the availability of
advertising inventory. This may, in turn, adversely affect our business,
results of operations and financial condition.

We depend on third-party relationships, many of which are short-term or
terminable, to generate traffic on our website.

   In order to expand our network, we have entered into a number of strategic
relationships which involve the payment of funds for prominent or exclusive
carriage of our healthcare information and services. These transactions are
premised on the assumption that the traffic we obtain from these arrangements
will permit us to earn revenue in excess of the payments made to partners. This
assumption is not yet proven, and if we are unsuccessful in generating
sufficient resources to offset these expenditures, we will likely be unable to
operate our business. We have entered into distribution relationships with
several companies, and we intend to enter into additional relationships in the
future. Most of these distribution relationships are short term in nature and
may not be renewed or may be canceled by our distribution partner. Although we
view our distribution relationships as a key factor in our overall business
strategy, our distribution partners may not view their relationships with us as
significant to their business, and they may later decide to end their
commitment to us or even decide to compete directly with us in the future. We
cannot guarantee that any distribution partner will perform its obligations as
agreed or contemplated or that we would be able to specifically enforce any
distribution agreement. Our arrangements with our distribution partners
generally do not establish minimum performance requirements, but instead rely
on the voluntary efforts of our distribution partners. Therefore, we cannot
guarantee that these relationships will be successful.

   Most of our arrangements with third-party Internet websites:

  . do not require future minimum commitments to use our services;

  . are not exclusive; and

  . are short-term or may be terminated at the convenience of the other
    party.

   In addition, we do not have agreements with many website operators that
provide links to onhealth.com, and those operators with which we do may
terminate such links at any time without notice. As a result, we cannot assure
you that our existing relationships will result in sustained business
relationships or the generation of significant revenue for us. Failure of one
or more of our strategic relationships to achieve or maintain market acceptance
or commercial success or the termination of one or more successful strategic
relationships could have a material adverse effect on our business, results of
operation and financial condition.

Since our website relies on some content that we do not create, it is possible
that we may not be able to provide such content in the future.

   While we produce much of the editorial content found on our website, some of
our content is licensed from third parties. Accordingly, we rely on the
expertise, technical capability, name recognition and willingness to syndicate
content for branding and distribution of others. As health-related content

                                       6
<PAGE>

grows on the web, there will be increasing competition for the best health
information suppliers. This may result in certain content becoming unavailable
or in significantly higher content prices. Such an outcome could make our
website less attractive or useful for a user and could have a material adverse
effect on our business and financial performance.

Our business is changing rapidly, which could cause our quarterly operating
results to vary and our stock price to fluctuate.

   Our revenue and operating results may vary significantly from quarter to
quarter due to a number of factors, not all of which are in our control. If we
have a shortfall in revenue in relation to our expenses, or if our expenses
precede increased revenue, then our results of operations would be materially
adversely affected. This would likely affect the market price of our common
stock in a manner which may be unrelated to our long-term operating
performance. Important factors which could cause our results to fluctuate
materially include:

  . our ability to attract and retain users;

  . our ability to attract and retain advertisers and sponsors;

  . our ability to attract and retain customers and maintain customer
    satisfaction for our existing and future e-commerce offerings;

  . new Internet websites, services or products introduced by us or our
    competitors;

  . the level of Internet and other online services usage;

  . our ability to upgrade and develop our systems and infrastructure and
    attract new personnel in a timely and effective manner;

  . our ability to successfully integrate operations and technologies from
    any acquisitions, joint ventures or other business combinations or
    investments; and

  . technical difficulties or system downtime affecting the operation of our
    website.

   In addition, as our market develops, seasonal and cyclical patterns may
emerge. These patterns may affect our revenue. We cannot yet predict to what
extent our operations will prove to be seasonal. Due to the factors noted above
and the other risks discussed in this section, you should not rely on quarter-
to-quarter comparisons of our results of operations as indicators of future
performance. It is possible that in some future periods our operating results
may be below the expectations of public market analysts and investors. In this
event, the price of our common stock may underperform or decrease.

Our success depends in large part on the continuing efforts of two individuals.
In addition, our success depends on our ability to continue to attract, retain
and motivate highly skilled employees.

   Our development and operation is substantially dependent on the services of
our President and Chief Executive Officer, Robert N. Goodman, and on our
Executive Vice President and General Manager, Rebecca Farwell. If we lost the
services of either Mr. Goodman or Ms. Farwell, our business would be severely
affected. Our ability to execute our growth plan and be successful also depends
on our continuing ability to attract, retain and motivate other highly skilled
employees. As we continue to grow, we will need to hire additional personnel in
all operational areas. Competition for personnel throughout the Internet
industry is intense. We may be unable to retain our key employees or attract,
assimilate or retain other highly qualified employees in the future. We have
from time to time in the past experienced, and we expect to continue to
experience in the future, difficulty in hiring and

                                       7
<PAGE>

retaining highly skilled employees with appropriate qualifications. If we do
not succeed in attracting new personnel or retaining and motivating our current
personnel, our business will be adversely affected.

To successfully compete in the Internet health field, we must continue to
improve the product we offer and increase the number of people using our
website.

   To do so, we will have to significantly increase our operating expenses to:

  . develop new distribution channels;

  . fund greater levels of research and development;

  . add editorial content;

  . increase our sales and marketing operations;

  . broaden our customer support capabilities; and

  . establish brand identity and strategic alliances.

   Such planned expansions, however, will require substantial capital. We
cannot guarantee that such capital will be available, or if available, that the
terms on which such capital is available will be acceptable to us. If we raise
additional cash through the issuance of equity or convertible debt securities:

  . the percentage ownership of our shareholders will be reduced;

  . shareholders may experience additional dilution upon the conversion of
    any such debt securities; and

  . such securities may have rights, preferences or privileges senior to
    those of the holders of common stock.

Any future acquisitions we make of companies or technologies may result in
disruptions to our business and/or the distraction of our management, due to
difficulties in assimilating acquired personnel and operations.

   We may acquire or make investments in complementary businesses,
technologies, services or products if appropriate opportunities arise. From
time to time we engage in discussions and negotiations with companies regarding
our acquiring or investing in such companies' businesses, products, services or
technologies, and we regularly engage in such discussions and negotiations in
the ordinary course of our business. Some of those discussions also contemplate
the other party making an investment in our company. We cannot assure you that
we will be able to identify future suitable acquisition or investment
candidates, or if we do identify suitable candidates, that we will be able to
make such acquisitions or investments on commercially acceptable terms or at
all. If we acquire or invest in another company, we could have difficulty in
assimilating that company's personnel, operations, technology and software. In
addition, the key personnel of the acquired company may decide not to work for
us. If we make other types of acquisitions, we could have difficulty in
integrating the acquired products, services or technologies into our
operations. These difficulties could disrupt our ongoing business, distract our
management and employees, increase our expenses and adversely affect our
results of operations. Furthermore, we may incur indebtedness or issue equity
securities to pay for any future acquisitions. The issuance of equity
securities would be dilutive to our existing shareholders.

Much of our website relies on owned or licensed intellectual property and we
cannot be sure that such rights are protected from the use of others, including
potential competitors.

   We regard much of our website and its technology as proprietary and try to
protect it by relying on trademarks, copyrights, trade secret laws and
confidentiality agreements with consultants. In

                                       8
<PAGE>

connection with our license agreements with third parties, we seek to control
access to and distribution of our technology, documentation and other
proprietary information. Even with all of these precautions, it could be
possible for someone else to either copy or otherwise obtain and use our
proprietary information without our authorization or to develop similar
technology independently. Effective trademark, copyright and trade secret
protection may not be available in every country in which our services are made
available through the Internet, and policing unauthorized use of our
proprietary information is difficult and expensive. We cannot be sure that the
steps we have taken will prevent misappropriation of our proprietary
information. Such misappropriation could have a material adverse effect on our
business. In the future, we may need to go to court to either enforce our
intellectual property rights, to protect our trade secrets or to determine the
validity and scope of the proprietary rights of others. Such litigation might
result in substantial costs and diversion of resources and management
attention.

   We currently license from third parties certain technologies incorporated
into onhealth.com. As we continue to introduce new services that incorporate
new technologies, we may be required to license additional technology from
others. We cannot be sure that these third-party technology licenses will
continue to be available on commercially reasonable terms, if at all.

We may have liability for products sold over, or information retrieved from,
our website.

   Because any of the materials on our website may be downloaded or viewed, and
such materials could be sent to others, we could be sued for:

  . defamation;

  . negligence;

  . copyright or trademark infringement;

  . medical malpractice or personal injury; or

  . other theories based on the nature and content of such materials.

   We could also be exposed to liability with respect to third-party
information that may be accessible:

  . through our website, or

  . through content and materials that may be posted by our users on
    discussion boards that we offer.

   Such claims might include, that by directly or indirectly providing links to
websites operated by third parties, we are liable for copyright or trademark
infringement or other wrongful actions by such third parties through such
websites. It is also possible that, if any third-party information provided on
our website contains errors, third parties could make claims against us for
losses they incur relying on such information. Insurance may not be adequate to
cover any such potential liabilities. Even if such claims do not result in
liability, we could incur significant costs in investigating and defending
against such claims.

   In addition, patients who file lawsuits against doctors often name as
defendants all persons or companies with any relationship to the doctors. As a
result, patients may file lawsuits against us based on advice rendered by
physicians through our website. In addition, a court or government agency may
take the position that our delivery of health information, or information
delivered by a third-party website that a consumer accesses through our
website, exposes us to malpractice or other personal injury liability for
wrongful delivery of healthcare services or erroneous health information. We
cannot assure you that the amount of insurance we maintain with insurance
carriers will be sufficient to cover

                                       9
<PAGE>

all of the losses we might incur from these claims and legal actions. In
addition, insurance for some risks is difficult, impossible or too costly to
obtain, and as a result, we may not be able to purchase insurance for some
types of risks.

We are party to litigation with a former officer of the Company.

   In June 1999, Jon Fisse, our former Chief Operating Officer, resigned from
OnHealth before we were able to reach agreement on the terms of his employment
agreement. Shortly thereafter, Mr. Fisse filed a lawsuit in the United States
District Court for the Southern District of New York asserting that OnHealth
terminated Mr. Fisse and violated his rights in connection with his separation
from OnHealth. As a result, Mr. Fisse is seeking damages which include
severance compensation, stock option benefits and compensatory and punitive
damages for allegedly defamatory statements contained in our press release
which announced Mr. Fisse's departure. The same day, we filed a declaratory
judgement action in the United States District Court for the Western District
of Washington seeking to declare that Mr. Fisse terminated his employment and
that we owe him no future remuneration or stock option benefits. If Mr. Fisse
were to be successful on all of his claims, our business and financial
condition could be materially and adversely affected. We believe we have valid
defenses against all of Mr. Fisse's claims and intend to defend against such
claims vigorously. See "Business--Legal Proceedings."

We have recently experienced and are currently experiencing rapid growth in our
business. If we are unable to manage this growth our business could be harmed.

   We have experienced and are currently experiencing a period of significant
growth. This growth has placed, and the future growth we anticipate in our
operations will continue to place, a significant strain on our resources. As
part of this growth, we will have to implement new operational and financial
systems and procedures and controls, expand, train and manage our employee
base, and maintain close coordination among our technical, accounting, finance,
marketing, sales and editorial staffs. If we are unable to manage our growth
effectively, our business, results of operations and financial condition could
be adversely affected. In addition, all of the members of our senior management
joined us in late 1997, 1998 or early 1999. Thus, we have a very new management
team which has not worked together for very long. We cannot assure you that our
management team will be able to work together effectively or successfully
manage our growth.

It is possible that we may have year 2000 problems. As a result, our computer
systems could fail.

   We could be affected by Year 2000 issues related to non-compliant
information technology systems or non-IT systems that we operate or that are
operated by third parties. We have substantially completed assessment of our
internal and external IT systems and non-IT systems. At this point in our
assessment, we are not currently aware of any Year 2000 problems relating to
systems we operate or that are operated by third parties that would have a
material adverse effect on our business, results of operations or financial
condition, without taking into account our efforts to avoid such problems.
Based on our assessment to date, we do not anticipate that costs associated
with remediating our non-compliant IT systems or non-IT systems will be
material, although there can be no assurance to such effect.

   We believe that the most likely worst case Year 2000 scenario is a failure
beyond our control, such as a prolonged telecommunications or electrical
failure. Such a failure would:

  . prevent us from operating our business;

  . prevent users from accessing our website; and

  . change the behavior of advertising customers or persons accessing our
    website.

                                       10
<PAGE>

   We believe that the primary business risks, in the event of such failure,
would include:

  . lost advertising revenue;

  . increased operating costs, loss of customers or persons accessing our
    website; and

  . other business interruptions of a material nature, as well as claims of
    mismanagement, misrepresentation or breach of contract.

   Any such problems would have a material adverse effect on our business. We
have not made any contingency plans to address such risks.

Our network could be penetrated. This could result in a disruption in our
website.

   Experienced programmers or hackers could attempt to penetrate our network
security. Because a hacker who is able to penetrate our network security could
misappropriate proprietary information or cause interruptions in our products
and services, we may be required to expend capital and resources to protect
against or to alleviate problems caused by such parties. In addition, we may
not have a timely remedy against a hacker who is able to penetrate our network
security. Such purposeful security breaches could have a material adverse
effect on our business, results of operations and financial condition. In
addition, the inadvertent transmission of computer viruses could expose us to a
risk of loss or litigation and potential liability.

If today's economic conditions deteriorate, our future results of operations
would be adversely affected.

   Time spent on the Internet by individuals, purchases of new computers and
purchases of membership subscriptions to Internet websites are typically
discretionary for consumers and may be particularly affected by adverse trends
in the general economy. The success of our operations depends to a significant
extent upon discretionary consumer spending, including economic conditions
affecting disposable consumer income such as employment, wages and salaries,
business conditions, interest rates, availability of credit and taxation. In
addition, our business strategy relies on advertising by, and agreements with,
other Internet companies. Any significant deterioration in general economic
conditions that adversely affected these companies could also have a material
adverse effect on our business.

We have no plans to pay cash dividends, and investors should not buy our common
stock expecting to receive dividends.

   We intend to retain all of our earnings, if any, for use in the business and
do not anticipate paying any cash dividends in the foreseeable future.

Our business may face additional risks and uncertainties not presently known to
us which could cause our business to suffer.

   In addition to the risks specifically identified in this Risk Factors
section or elsewhere in this prospectus, we may face additional risks and
uncertainties not presently known to us or that we currently deem immaterial
which ultimately impair our business, results of operations and financial
condition.

Risks Related to Our Industry

Consumers and the healthcare industry must accept the Internet as a source of
healthcare content and services for our business model to be successful.

   To be successful, we must attract to our network a significant number of
consumers as well as other participants in the healthcare industry. To date,
consumers have generally looked to healthcare professionals as their principal
source for health and wellness information. Our business model assumes that
consumers will use healthcare information available on our network, that
consumers will access

                                       11
<PAGE>

important healthcare needs through electronic commerce using our website, and
that local healthcare organizations will affiliate with us. This business
model is not yet proven, and if we are unable to successfully implement our
business model, our business will be materially adversely affected.

The Internet industry is highly competitive and changing rapidly, and we may
not have the resources to compete adequately.

   The number of Internet websites offering users healthcare content, products
and services is vast and increasing at a rapid rate. These companies compete
with us for users, advertisers, e-commerce transactions and other sources of
online revenue. In addition, traditional media and healthcare providers
compete for consumers' attention both through traditional means as well as
through new Internet initiatives. We believe that competition for healthcare
consumers will continue to increase as the Internet develops as a
communication and commercial medium.

   There are a number of competitors delivering online health content who will
also seek advertising revenue, and it is likely that more competitors will
emerge in the near future. Such competitors include, among others:
WebMD/Healtheon, Mayo Health O@sis, drkoop.com, Mediconsult, Medscape and
InteliHealth. Many of these competitors have more cash available to spend,
longer operating histories and stronger brand recognition than we do. Some
have internal distribution or other opportunities to support their business
that we neither have nor are able to replicate for a reasonable investment. As
expressed above, we believe that the number of other health care Internet
companies that rely on Internet-based advertising revenue will increase
substantially in the future. Accordingly, we will likely face increased
competition, resulting in increased pricing pressures on our advertising
rates, which could have a material adverse effect on our business.

   We believe that the principal competitive factors in attracting advertisers
to our website include:

  . the amount of traffic on our website;

  . brand recognition;

  . customer service;

  . the demographics of our user base;

  . our ability to offer targeted audiences; and

  . the overall cost effectiveness of the advertising medium we offer.

Our business is dependent on the continuous, reliable and secure operation of
our website and related tools and functions we provide.

   All companies that rely on the Internet are dependent upon the continuous,
reliable and secure operation of Internet servers and related hardware and
software. If that service is interrupted, consumers would be inconvenienced
and commercial clients would suffer from a loss in advertising or transaction
delivery. This would result in a revenue loss to us. Even though our computer
and communications hardware are protected through physical and software
safeguards, they are still vulnerable to fire, earthquake, flood, power loss,
telecommunications failures, physical or software break-ins and similar
events. We do not have a complete back-up for all of our computer and
telecommunications facilities and do not carry business interruption insurance
to protect us in the event of a catastrophe. Such an event could lead to
significant negative impacts on our business. We also depend on third parties
to provide users with web browsers and Internet and online services necessary
for access to our website. In the past, users have occasionally experienced
difficulties with Internet and online services due to system failures,
including failures unrelated to our systems. Any sustained disruption in
Internet access provided by third parties could have a material adverse effect
on our business.

   We retain confidential customer information in our database. Therefore, it
is critical that our facilities and infrastructure remain secure and are
perceived by consumers to be secure. Despite the

                                      12
<PAGE>

implementation of security measures, our infrastructure may be vulnerable to
physical break-ins, computer viruses, programming errors or similar disruptive
problems. A material security breach could damage our reputation or result in
liability to us.

Since we operate an Internet-based network, our business is subject to
government regulation relating to the Internet which could impair our
operations.

   Because of the increasing use of the Internet as a communication and
commercial medium, the government has adopted and may adopt additional laws and
regulations with respect to the Internet covering such areas as:

  . user privacy,

  . pricing,

  . content,

  . taxation,

  . copyright protection, and

  . the distribution of health care products or advice over the Internet.

   Since we operate a healthcare network over the Internet, our business is
subject to government regulation specifically relating to medical devices, the
practice of medicine and pharmacology, healthcare regulation, insurance and
other matters unique to the healthcare area. Laws and regulations have been or
may be adopted with respect to the provision of healthcare-related products and
services online, covering areas such as:

  . the regulation of medical devices;

  . the practice of medicine and pharmacology and the sale of controlled
    products such as pharmaceuticals online;

  . the regulation of government and third-party cost reimbursement; and

  . the regulation of insurance sales.

   FDA Regulation of Medical Devices. Some computer applications and software
are considered medical devices and are subject to regulation by the United
States Food and Drug Administration. We do not believe that our current
applications or services will be regulated by the FDA; however, our
applications and services may become subject to FDA regulation. Additionally,
we may expand our application and service offerings into areas that subject us
to FDA regulation. We have no experience in complying with FDA regulations. We
believe that complying with FDA regulations would be time consuming, burdensome
and expensive and could delay or prevent our introduction of new applications
or services.

   Regulation of the Practice of Medicine and Pharmacology. The practice of
medicine and pharmacology requires licensing under applicable state law. We
have endeavored to structure our website and affiliate relationships to avoid
violation of state licensing requirements, but a state regulatory authority may
at some point allege that some portion of our business violates these statutes.
Any such allegation could result in a material adverse effect on our business.
Further, any liability based on a determination that we engaged in the practice
of medicine without a license may be excluded from coverage under the terms of
our current general liability insurance policy.

   Federal and State Healthcare Regulation. We earn a service fee when users on
our website purchase prescription pharmacy products from certain of our e-
commerce partners. Federal and state anti-kickback laws prohibit granting or
receiving referral fees in connection with sales of pharmacy products that are
reimbursable under federal Medicare and Medicaid programs and other
reimbursement programs. Although there is uncertainty regarding the
applicability of these regulations to our e-commerce revenue strategy, we
believe that the service fees we receive from our e-commerce partners are for
the primary purpose of marketing and do not constitute payments that would
violate federal or state "anti-kickback" laws. However, if our program were
deemed to be inconsistent with

                                       13
<PAGE>

federal or state law, we could face criminal or civil penalties. Further, we
would be required either not to accept any transactions which are subject to
reimbursement under federal or state healthcare programs or to restructure our
compensation to comply with any applicable anti-kickback laws or regulations.
In addition, similar laws in several states apply not only to government
reimbursement but also to reimbursement by private insurers. If our activities
were deemed to violate any of these laws or regulations, it could cause a
material adverse affect on our business, results of operations and financial
condition.

Internet capacity constraints may impair the ability of consumers to access our
website, which could hinder our ability to generate advertising revenue.

   Our success will depend upon the ability of the communications industry to
provide Internet access and carry Internet traffic. The Internet may not prove
to be a viable commercial medium because of:

  . inadequate development of the necessary infrastructure such as a reliable
    network backbone;

  . timely development of complementary products such as high speed modems;

  . delays in the development or adoption of new standards and protocols
    required to handle increased levels of Internet activity; or

  . increased government regulation.

   If the Internet continues to experience significant growth in the number of
users and the level of use, then the Internet infrastructure may not be able to
continue to support the demands placed on it.

Market prices of emerging Internet companies have been highly volatile, and the
market for our stock may exhibit volatility as well.

   The stock market has experienced significant price and trading volume
fluctuations, and the market prices of technology companies, particularly
Internet-related companies, have been extremely volatile. Exceptional share
price and trading volume changes have accompanied recent public offerings by
Internet companies in the first days and weeks after the securities were
released for public trading. Investors may not be able to resell their shares
at or above the initial public offering price. In the past, following periods
of volatility in the market price of a public company's securities, securities
class action litigation has often been instituted against that company. Such
litigation could result in substantial costs and a diversion of management's
attention and resources.

                                Use of Proceeds
- --------------------------------------------------------------------------------

   We expect to use the net proceeds from sales pursuant to this prospectus to
finance operations while we continue to incur operating losses, to expand our
marketing efforts and for general corporate purposes, including advertising and
brand promotion, distribution and marketing relationships and the remainder for
content development and licensing and working capital. We may also use a
portion of the proceeds for the acquisition of, or investment in, companies,
technologies or assets that complement our business.

   Pending these uses, we intend to invest the net proceeds from this offering
in short term, investment grade, interest bearing instruments.

          Management's Discussion and Analysis of Financial Condition
                           and Results of Operations
- --------------------------------------------------------------------------------

Overview

   We are a leading independent source of original, informative, timely and
trusted consumer-oriented health and wellness information, products and
services on the Web. Our website, onhealth.com, is a consumer-driven online
health destination dedicated to the management of family health and well-being.
By providing users with original in-depth reporting, substantive resources and
references, community discussions, direct access to experts, interactive tools
and exclusive "smart" search capabilities, onhealth.com combines the strength
of credible journalism with the power of online interactivity.

   Until January 1998, our traditional line of business had been CD-ROM
development, production and distribution. We were also a supplier of video,
animation and graphic assets to a health and medical cable television channel.
In late 1997, our Board of Directors revised our business strategy and brought
in an entirely new management team and other key employees skilled in the
development of Internet websites. In 1998, we focused on developing an
Internet-delivered, consumer-oriented health and wellness website. Accordingly,
our revenue model as compared to prior years, has changed to concentrate on
online revenue sources as opposed to CD-ROM based product sales and licensing.

   In July 1998, we relaunched the onhealth.com website and focused on
generating advertising revenue. We have a wide variety of advertisers on our
website including healthcare and other non-healthcare advertisers. In March
1999, we launched a shopping area on our site designed to offer our consumers
the ability to purchase a wide variety of health and wellness products and
related products. To date, we have e-commerce relationships with drugstore.com,
VitaminShoppe, Amazon.com, SelfCare, American Greetings, ProFlowers, Whole
Foods Market, greenmarketplace.com and enews.com, and expect to continue to add
additional categories and partners.

   Net revenue for the six month period ended June 30, 1999 increased by
$296,000, or 61%, to $781,000, from $485,000 in the same period in 1998. The
increase in revenue is primarily due to increased online revenue generated by
our onhealth.com web site, which was redesigned and relaunched in July 1998,
partially offset by a reduction in contract development and other revenue. An
increase in user traffic and the number of site sponsorship and advertising
clients over the same six month period in the prior year accounted for the
increase in online revenue. E-commerce revenue is the result of new contracts
entered into during 1999. The decrease in contract development revenue and
other generally reflects our shift toward online efforts. We do not anticipate
receiving any significant

                                       17
<PAGE>

revenue from contract development and other or product sales and licensing in
the future. E-commerce revenue includes fees for guaranteed impressions,
exclusivity fees and revenue sharing. The negative product sales and licensing
revenues in 1998 are a result of CD ROM product returns.

Gross margin

   Gross margin as a percentage of net revenue for the six month period ended
June 30, 1999 was 87% compared to a negative gross margin of 53% for the same
period in the previous year. The improvement in gross margin for the first six
months of 1999 was primarily due to the high margins of online revenue in
relation to the gross margins achieved in the first six months of 1998 for CD-
ROM revenue. The negative gross margin in 1998 was the result of CD-ROM royalty
expenses, CD-ROM inventory write-offs and royalty expenses related to cable
television licensing revenue. In 1999, cost of revenue consists primarily of
third-party royalties relating to content sales, costs of advertising and
sponsorship revenues, and costs of e-commerce.

Operating expenses

   Total operating expenses for the six month period ended June 30, 1999
increased $7.8 million or 186%, to $12.1 million from $4.2 million. The
increase was primarily due to increased sales and marketing efforts related to
the Company's onhealth.com web site and increased product development,
editorial and design expenses.

   Product development, editorial and design. The increase in product
development, editorial and design expenses for the six month period ended June
30, 1999 of $1.5 million, or 96%, from the same period in 1998 was primarily
due to an increase in the use of outside contractors and headcount. Product
development, editorial and design expenses consist primarily of compensation,
consulting fees, third-party content acquisition costs and web site maintenance
and enhancement costs related to the Company's onhealth.com web site.

   Sales and marketing. The increase in sales and marketing expenses for the
six month period ended June 30, 1999 of $5.6 million, or 390%, from the same
period in 1998 was primarily the result of increased advertising expenses
related to the Company's onhealth.com web site and increased headcount.
Marketing expenses include costs related to the launch of a broad-based
consumer targeted advertising campaign expected to commence in the third
quarter of 1999.

   General and administrative. The increase in general and administrative
expenses for the six month period ended June 30, 1999 of $764,000 or 62%, from
the same period in 1998 was primarily due to an increase in legal fees and
settlements, travel and headcount. Legal fees and settlements include $273,000
for settlement and legal costs related to the final settlement of the T. Randal
Productions lawsuit, which is in addition to the $677,000 which had been
accrued at December 31, 1998.

Interest Income

   The increase in interest income for the six month period ended June 30, 1999
of $175,000, or 324%, from the same period in 1998 is due to the interest
earned on cash received from the private placement completed during the first
quarter of 1999.

Other income, net

   Other income, net for the six month period ended June 30, 1998 includes a
$562,000 gain related to the collection of a previously reserved receivable,
$1,000 of other income and a $281,000 expense related to cable television
licensing royalties.

</TABLE>

   Net revenue for 1996, 1997 and 1998 of $9.4 million, $3.7 million and $1.5
million, respectively, represents a decrease of 60% from 1997 to 1998 and 60%
from 1996 to 1997. The 1997 to 1998 decrease is due to a substantial reduction
in product sales and licensing revenue of $1.2 million, or 62%, a reduction in
contract development revenue and other of $840,000, or 69%, and a reduction in
cable television licensing revenue of $493,000, or 100%. These decreases were
partially offset by a $330,000, or 569%, increase in online revenue. The 1998
product sales and licensing revenue includes a $603,000 payment related to
minimum sales requirements from a terminated CD-ROM distribution agreement. The
decrease from 1996 to 1997 is due to a substantial reduction in product sales
and licensing revenue of $3.1 million, or 61%, a substantial reduction in cable
television licensing revenue of $1.5 million, or 75%, and a decrease in online
revenue from $1.0 million to $58,000.

Product sales and licensing revenue

   Product sales and licensing revenue has declined steadily over the past few
years. The decrease generally reflects market conditions for CD-ROM products,
our cancellation of a CD-ROM distribution agreement, and the lack of new CD-ROM
product releases as we shifted our focus toward online efforts. In 1995, we
entered into a five year distribution agreement which allowed for the
promotion, marketing and distribution of certain of our CD-ROM products. The
agreement also provided for minimum levels of sales through the year 2000. In
December 1998, we received a $603,000 payment related to minimum sales
requirements from the termination of the CD-ROM distribution agreement. We do
not anticipate receiving any product sales or licensing revenue from CD-ROM
products in the future as we have discontinued this line of business.

Online revenue

   From 1997 to 1998, online revenue increased from $58,000 to $388,000, an
increase of $330,000, or 569%. This increase reflects increased advertising
revenue and website sponsorship from our website which we re-designed and re-
launched in July 1998. The 1997 online revenue of $58,000 included website
sponsorships, advertising and premium services revenue related to onhealth.com
and the former O@sis website. In September 1997, we entered into an agreement
with Mayo Foundation which included the full transfer to Mayo of our ownership
interest in the O@sis website. The $1,000,000 of online revenue in 1996 relates
to nonrefundable advances paid to us under an exclusive agreement signed with
AT&T in October 1995 and the discontinuance by AT&T of the AT&T Health website
in August 1996.

Contract development revenue and other

   From 1997 to 1998, contract development revenue and other decreased
$840,000, or 69%. The decrease generally reflected our shift toward online
efforts. From 1996 to 1997, contract development revenue and other decreased
slightly, representing management's efforts to control costs and focus on more
profitable contracts.

                                       19
<PAGE>

Cable television licensing revenue

   Cable television licensing revenue reflects revenue from our content and
royalty agreement with America's Health Network ("AHN"). Under the agreement,
we began licensing multimedia content to AHN in May 1995 and were to receive
minimum licensing royalties over the life of the agreement. The revenue was
being recognized evenly over the expected life of the agreement. Due to the
gradual increase in actual payments versus the straight-line revenue
recognition policy, we recorded a receivable for the difference between the
revenue recognized and the cash received during the early years of the
contract. The $1.5 million decrease in revenue from 1996 to 1997 was a result
of us not receiving payments due to AHN's financial difficulties. In June 1997,
as a result of not receiving our quarterly payment, we fully reserved the
outstanding AHN receivable.

Gross margin

   Gross margin as a percentage of net revenue was 50% in 1998 compared to 32%
in 1997. The improvement in gross margin in 1998 was primarily due to the high
margins on online revenue and the product sales distribution agreement
termination revenue.

   Gross margin as a percentage of net revenue was 32% in 1997 compared to 46%
in 1996. The decrease in gross margin in 1997 was partially due to continued
lower gross profits realized on CD-ROM retail sales, but was primarily due to
decreases in higher margin cable television licensing and online revenue.

Operating expenses

   In 1998, product development, editorial and design costs were principally
related to our website. In 1997, development costs included primarily
onhealth.com development costs and CD-ROM development costs. From 1997 to 1998,
product development expenses decreased from $4.2 million to $3.7 million, a
decrease of $499,000, or 12%. The decrease reflects the lack of new 1998 CD-ROM
product releases, and a shift towards online publishing.

   Product development, editorial and design expenses. Product development
expenses were $4.2 million for 1997, a decrease of $1.4 million, or 25%, from
1996, due to our release of fewer CD-ROM products and our shift to online
publishing.


   Sales and Marketing. Sales and marketing expenses in 1998 were $5.6 million
as compared to $1.3 million in 1997, an increase of $4.3 million, or 318%. The
increase primarily relates to increased marketing activities for our website.
In July 1998, we began a marketing campaign to promote the launch of the
website which included online and radio advertising. In addition, we incurred
distribution costs related to agreements signed in July 1998 with GeoCities and
Go Network.


   Sales and marketing expenses were $1.3 million in 1997, compared to $2.7
million in 1996. The decrease of 50% was a result of the release of fewer CD-
ROM titles in 1997, decreases in expenditures to promote our products and a
smaller expense structure created by the downsizing of operations in late 1996.

   General and Administrative. General and administrative expenses were $2.4
million in 1998, compared to $6.9 million in 1997, a decrease of $4.5 million,
or 65%. General and administrative expenses consist primarily of compensation
to administrative and executive personnel, fees for professional services,
facility costs and bad debt expenses. The large decrease in 1998 relative to
1997 reflects substantially reduced legal costs, reduced bad debt costs, and
general cost cutting measures including reduced rent costs from our relocation
to smaller facilities. The 1997 costs also included certain special charges
including costs to relocate the Company from Minneapolis to Seattle.


   General and administrative expenses were $6.9 million in 1997 compared to
$6.4 million in 1996. The increase of 8% was due to extensive litigation and
special charges in 1997. We recorded $808,000

                                       20
<PAGE>

in expenses related to a settlement of litigation with Viridis, Inc. and
received an adverse jury award of $480,000, plus interest from a dispute with
T. Randal Productions, et al. in 1997. In the fourth quarter of 1997, we
recorded charges of $1.6 million for the relocation of our headquarters from
Minneapolis to Seattle. These charges included $610,000 in severance to
officers and employees and $962,000 for asset dispositions and lease
termination costs. Also in 1997, we wrote-off $1.7 million in other assets
related to an agreement with Time Life, Inc. Excluding the litigation and
special charges, our reduction in general and administrative expenses was the
result of the downsizing of the facilities and personnel and management's
efforts to streamline operating costs.

Net interest income (expense)

   Net interest income was $84,000 in 1998 compared to net interest expense of
$158,000 in 1997. The net interest income in 1998 relative to net interest
expense in 1997 reflects the lack of debt in 1998 relative to 1997. The 1997
net interest expense includes interest expense of $264,000 related to $3.5
million in convertible subordinated debentures, which were outstanding for ten
months in 1997. These debentures were converted to common stock in October
1997.

   Net interest expense was $158,000 in 1997 compared to net interest income of
$169,000 in 1996. The net interest expense in 1997 versus net interest income
in 1996 reflects lower interest income earned from cash and cash equivalents
balances in 1997 relative to 1996 and higher interest expenses in 1997 related
to 1996. The interest expense relates to $3.5 million in convertible
subordinated debentures that were outstanding for two months in 1996 versus ten
months in 1997.

Other income (expense)

   Other expense was $4,000 in 1998 compared to other income of $473,000 in
1997. The 1998 other expense of $4,000 included a $285,000 loss related to
fixed asset disposals, a $562,000 gain related to the collection of a
previously reserved accounts receivable, and a $281,000 revenue-sharing payment
related to the collection of the receivable.

   The 1997 other income of $473,000 included a $2.7 million cash payment that
we received in connection with the transfer of ownership of the O@sis website
to Mayo. This was partially offset by other expense of $2.2 million in
connection with our conversion of convertible subordinated debentures to common
stock in October 1997. These debentures were originally issued in November
1996. The expense represents the excess of the fair market value of common
stock issued over the fair value of the common stock issuable pursuant to the
original conversion terms of the debentures.

Limitation on Use of Net Operating Loss and Other Tax Credit Carryforwards

   At December 31, 1998, we had available net operating loss carryforwards of
approximately $81.9 million and available research and development credits of
approximately $339,000 for federal income tax purposes. The net operating loss
carryforwards and the credits expire at various times through 2013. These
carryforwards are subject to the limitations of Internal Revenue Code Section
382, which provides limitations on the availability of net operating losses to
offset current taxable income if significant ownership changes have occurred
for federal tax purposes. We incurred "ownership changes," pursuant to
regulations currently in effect under Internal Revenue Code Section 382, as a
result of sales of our preferred stock in 1992 and 1993 and may have incurred
ownership changes since that time.

Liquidity and Capital Resources

   At July 31, 1999, we had positive working capital of $1,976,000 compared
with negative working capital of $1.2 million at December 31, 1998. At July 31,
1999, we had cash and cash equivalents of $1.4 million. During the first six
months of 1999, total cash used by operating activities was $9.5 million, which
was principally due to our net loss for the period partially off-set by an
increase in current liabilities. During the year ended December 31, 1998, total
cash used by operating activities was $10.0 million, which was primarily due to
the net loss of $10.9 million. During the six

                                       21

months of 1999, investing activities used net cash of $532,000 for purchases of
computer equipment. During the year ended December 31, 1998, investing
activities used net cash of $472,000 for purchases of computer equipment.
During the first six months of 1999, financing activities provided cash of
$16.8 million: $14.1 million, net of financing costs, from the private
placement of common stock in January 1999, $1.6 million, from the exercise of
warrants, and $1.1 million from the exercise of stock options. During the year
ended December 31, 1998, financing activities provided cash of $10.1 million:
$5.7 million from the private placement of common stock, $5.0 million from the
issuance of convertible redeemable preferred stock and $1.1 million from the
exercise of stock options.

   We believe that our cash and cash equivalents, together with the proceeds we
expect to receive from sales pursuant to this prospectus, will be sufficient to
fund our operations through December 31, 1999. Operations generated a negative
cash flow during 1996, 1997 and 1998, and we expect a significant use of cash
in 1999 and 2000 as we market and expand our website. Any material unforeseen
increase in expenses or reductions in projected revenue will likely require us
to seek additional debt or equity financing. If additional cash is required we
may need to reduce our expenditures or curtail certain operations. We cannot be
sure that additional capital, on a debt or equity basis, will be found, or if
found that it will be on economically viable terms.

Year 2000

   The Year 2000 issue refers to the potential for system and processing
failures of date-related data resulting from computer-controlled systems using
two digits rather than four to define the applicable year. For example,
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in similar normal business activities.

   We could be affected by Year 2000 issues related to non-compliant IT systems
or non-IT systems that we operate or that are operated by third parties. We
have substantially completed assessment of our internal and external (third-
party) IT systems and non-IT systems. At this point in our assessment, we are
not currently aware of any Year 2000 problems relating to systems we operate or
that are operated by third parties that would have a material effect on our
business, results of operations or financial condition, without taking into
account our efforts to avoid such problems. Based on our assessment to date, we
do not anticipate that costs associated with remediating our non-compliant IT
systems or non-IT systems will exceed $100,000, although there can be no
assurance to such effect, and any such cost will be funded through operating
cash flows. To date, we have not incurred any significant costs related to the
assessment of, and preliminary efforts in connection with, our Year 2000
project and the development of a remediation plan. We do not currently expect
that the Year 2000 issue will materially adversely affect our financial
condition or results of operations. We cannot guarantee that our systems or the
systems of other companies on which our systems rely will be timely converted
or that other companies will convert their systems at all or in a manner
compatible with our systems. If there is a delay in converting these systems or
if the conversions are not compatible, it could have a material adverse effect
on our business, financial condition and results of operations.

   To the extent that our assessment is finalized without identifying any
additional material non-compliant IT systems we operate or that are operated by
third parties, the most reasonably likely worst case Year 2000 scenario is a
systemic failure beyond our control, such as a prolonged telecommunications or
electrical failure. Such a failure could prevent us from operating our
business, prevent users from accessing our website, or change the behavior of
advertising customers or persons accessing our website. We believe that the
primary business risks, in the event of such failure, would include, but not be
limited to, lost advertising revenue, increased operating costs, loss of
customers or persons accessing our website, or other business interruptions of
a material nature, as well as claims of mismanagement, misrepresentation, or
breach of contract, any of which could have a material adverse effect on our
business, results of operations and financial condition. We have not made any
contingency plans to address such risks.

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

Business Overview

   We are a leading independent source of original, informative, timely and
trusted consumer-oriented health and wellness information, products and
services on the Web. Our website, onhealth.com, is a consumer-focused online
health destination dedicated to the management of personal and family health
and well-being. We employ ten full-time staff editors and writers and we use
over 100 health and medical writers and contributors, enabling us to update our
website daily with original health-related features. By providing users with a
broad range of original in-depth reporting, substantive resources and
references, community discussions, direct access to experts, interactive tools
and exclusive Personal Health Info Tracker search capabilities, onhealth.com
combines the strength of credible journalism with the power of online
interactivity.

   We launched our website in July 1998. During July 1999, according to Media
Metrix, onhealth.com attracted nearly 1,200,000 unique users, an increase of
182% from our March 1999 unique users, which ranks onhealth.com as one of the
most trafficked consumer health content websites in July 1999. According to
Internet Profile Corporation, in June 1999, onhealth.com attracted 1,563,785
visits, an increase of 61% from our March 1999 visits. We have launched a
coordinated traditional media advertising and public relations campaign
designed to build our brand through the use of television, radio, outdoor,
print and online media. We also distribute in excess of 60,000 daily and weekly
broadcast e-mails to registered users who have requested our Daily Briefing,
Weekly Newsletter and Health Info Tracker. This private and personalized e-mail
allows our users to stay current on the health-related subjects most important
to themselves and their families. To date, we have developed distribution
partnerships and content sharing relationships resulting in over 950 websites
that drive traffic to our website. We intend to aggressively expand our content
and distribution partnerships with both online and traditional media partners
that can direct additional users to our website.

   Because we are not aligned or affiliated with any one individual,
institution or medical organization, we are able to provide an independent
voice and serve as a trusted consumer advocate for health-related issues. We
believe this will allow us to build a loyal and dedicated audience that will
fuel multiple revenue opportunities. While we believe the demographics of our
users are highly attractive to advertisers, we are developing our website to
generate revenue opportunities from multiple sources, including
advertising/sponsorships, e-commerce transactions and content syndication. We
have a shopping area on our website designed to offer our users a wide variety
of health and wellness products including prescription and over-the-counter
drugs, vitamins, herbs, books, magazines, foods, home products and gifts.

Industry

   We believe that the aging of the U.S. population, the rise of restrictive
managed care programs and the emergence of the Internet have combined to create
substantial demand for resources and communities that enable consumers to
better understand and control the decisions that affect their personal health.

   The Internet is emerging as an important alternative to traditional media
enabling millions of consumers to seek information, communicate and conduct
commerce. According to International Data Corporation, the number of Internet
users worldwide will grow from approximately 100 million in 1998 to 320 million
by 2002. The Internet is empowering consumers by providing immediate, low cost
access to highly topical, interactive content and communities. In addition, the
Internet is enabling advertisers and online merchants to inexpensively reach
vast, yet highly targeted audiences, and to measure in real-time the
effectiveness of their programs. We believe that healthcare industry

                                       23
<PAGE>

constituents will benefit from the Internet's unique attributes as an open,
low-cost, flexible technology for the exchange of information and for commerce.

   The healthcare industry is the single largest segment of the U.S. economy,
representing approximately $1.2 trillion in spending or 14% of the U.S. gross
domestic product. Over the past decade, the healthcare industry has changed
radically as employers seeking to reduce their healthcare costs have turned
from indemnity insurance to managed health plans. Approximately 180 million
people, or 90% of the insured U.S. population, are now subject to some form of
managed care. We believe that consumers increasingly question the motivations
of their caregivers and are more inclined to take an active role in the
decisions that affect their health and wellness as well as that of their
families.

   Consumers are seeking more information in order to actively manage their
personal health and wellness. However, traditional sources of healthcare
information such as print publications, are often voluminous, reference-
oriented and outdated while other media, including television and radio, lack
the analysis and insight consumers demand. As a result, many consumers are
turning to the Internet to obtain health information. According to Cyber
Dialogue, an industry research firm, during 1998, approximately 22 million
adults in the United States searched online for health and medical information.
Cyber Dialogue estimates that approximately 70% of the persons searching for
health and medical information online believe the Internet empowers them by
providing them with information before and after they go to a doctor's office.
Cyber Dialogue also estimates that in the year 2000, the number of adults in
the United States searching for online health and medical information will grow
to approximately 33 million, and they will spend approximately $150 billion for
all types of health-related products and services.

   Industry research has indicated that women tend to be the health care
decision-makers within their households and therefore are the primary seekers
of health and wellness information. Internet use among women has increased
rapidly in recent years (from 5% of all users in early 1994 to an estimated 51%
by the end of 1999). These trends are of particular importance to advertisers
since women are estimated to have disproportionate control or influence over
consumer spending in the United States. Spending on advertising targeted to
women is generally considered to represent the largest single category of
advertising in the United States. According to industry experts, women control
66% of family healthcare expenditures, make 75% of all healthcare decisions and
control or influence over 80% of all purchase decisions. In addition, industry
research indicates that women spend less time than men surfing the Internet and
tend to spend more time visiting destinations that meet their needs.

   There are currently over 15,000 websites providing health information. The
quality and breadth of these websites varies widely and to date no clear brand
has emerged as the leading provider of trusted consumer-oriented health and
wellness information on the Internet. Most of these websites do little more
than repurpose and repackage non-proprietary content without tailoring such
content for the consumer and providing context, insight or analysis. Many offer
little disclosure about their affiliations, the sources of their information
and potential conflicts of interest. Additionally, many health websites are
poorly designed, difficult to navigate and do not understand the needs of women
as the principle gatekeepers of the healthcare dollar. Accordingly, we believe
there is a substantial and growing unmet need for a well-known, trusted,
comprehensive health-related website that addresses consumers' health needs
accurately and intelligently while providing a satisfying consumer experience.
Moreover, we believe that such a website will have the ability to generate
significant revenue from a variety of sources, including advertising and
commerce.

Our Strategy

   Our goal is to become the premier source of consumer-oriented health and
wellness information and services on the Internet. We intend to achieve this
goal by implementing the following strategies:

                                       24
<PAGE>

   Leverage and Enhance Our Expansive Proprietary Health Content. We believe
that the breadth, depth and quality of the proprietary health content we
provide, together with the fact that our content is tailored for the consumer,
substantially differentiates onhealth.com from other health information
websites and represents a competitive advantage. During the remainder of 1999,
we will aggressively add reference material, condition center partners,
applications, tools and personalization functionality. In addition, we have
partnered exclusively in certain disease areas with best-of-breed content
partners including the Cleveland Clinic, Beth Israel Deaconess Cancer Center,
the Mount Sinai Cardiovascular Institute, the Scripps Clinic and the
International Diabetes Center. Our content, which is archived and searchable,
ranges from clinical medicine to alternative medicine and from reference
material to journalistic exploration of relevant health topics. We are not
affiliated with any single health system, payor or individual, and we are free
to provide multiple perspectives on health topics. We intend to continue to
differentiate OnHealth by expanding and enhancing our proprietary consumer
health content.

   Provide Consumers with a Compelling Health Experience. We are highly focused
on providing consumers who visit our website with a compelling experience that
not only addresses their initial needs, but also gives them multiple reasons to
spend more time at and return more often to our website. Accordingly, our
website is designed for easy navigation and is intended to be both informative
and engaging. Our experienced creative team understands the multi-dimensional
nature of publishing on the Internet. The team is adept at mixing information,
images, interactive tools, personalization and rich media.

   Establish Onhealth.com as the Premier Brand for Health and Wellness
Information on the Internet. We intend to establish onhealth.com as the premier
health brand that consumers associate with trustworthiness and view as their
one-stop, complete resource for health and wellness information on the
Internet. To this end, we have launched a coordinated advertising and public
relations campaign using television, radio, outdoor, print and online media. We
plan to also continue to expand our distribution agreements with search
engines, portals and Internet service providers. Currently, over 950 websites
drive traffic to onhealth.com, including Snap.com, Yahoo and AOL's Digital
City's Network. Our management team is experienced at building consumer brands
for Internet and traditional media companies including MSNBC, The Discovery
Channel, ABCNEWS.com, Starwave/ESPN Internet Ventures and Conde Nast
Publications. We believe that employing traditional media branding techniques
will be critical to establishing a leading brand.

   Capitalize on Revenue Generating Opportunities. We intend to leverage the
growth in our consumer base by exploiting opportunities to develop multiple
revenue streams including advertising/sponsorship, e-commerce/transaction,
syndication of content and subscription to premium services. In the first
quarter of 1999, we launched a health products shopping area on our website and
we plan to continue to expand our relationships with leading web e-tailers to
offer consumers a full range of health and wellness related products and
services. Unlike many of our competitors, we have an opportunity to leverage
our proprietary content and interactive tools through syndication to provide an
additional revenue stream. We also believe that health consumers are interested
in premium subscription offerings such as personalized smoking cessation and
dietary programs, personalized health and condition reports and direct access
to leading medical experts. By pursuing diversified revenue opportunities, we
seek to reduce our dependence on and exposure to any single revenue stream.

   Engage in Selective Acquisitions and Strategic Partnerships. We believe that
there will be significant consolidation in the online health category. We have
a focused business development effort, and are seeking acquisition and
strategic partnership opportunities. We are continually evaluating strategic
relationships with various distribution and media outlets that can serve to
drive traffic to our website and/or increase opportunities to generate e-
commerce/transaction revenue. We intend to pursue

                                       25
<PAGE>

acquisitions that have the potential to augment our current operations in six
primary categories: content, applications, products, revenue, traffic and
intellectual capital/people.

The OnHealth Website

   Onhealth.com provides timely and relevant coverage of health news and
issues, substantive resources and references, community discussions, direct
access to experts, interactive tools and exclusive Health Info Tracker search
capabilities to enable consumers to actively manage the health and well-being
of themselves and their families. On our website, consumers will find complete
coverage of important health issues and broad database reference materials in
an interactive, visually pleasing and personalized format. The site consists of
the following services and features, many of which are unique to OnHealth.

Branding

   Our objective is to create the premier consumer health and wellness brand on
the Internet. While there has been a proliferation of health-related websites
on the Internet, we believe that no single participant has developed a
preeminent, recognizable brand with online consumers. We have launched a
coordinated traditional media advertising and public relations campaign
designed to build the OnHealth brand through the use of television, radio,
outdoor, print and online media. We have set a preliminary integrated budget of
$25 million to be spent over the next year and we have retained TBWA/Chiat/Day
and Fleishman-Hillard to assist us in this undertaking.

   Our management team has a proven track record of developing content and
building leading consumer brands at Internet and traditional media companies
such as MSNBC, The Discovery Channel, ABCNEWS.com, Starwave/ESPN Internet
Ventures and Conde Nast Publications. We believe that the strength of our
management team is a key factor that differentiates us from many of the other
Internet health companies. While many online providers of health information
have established branding strategies based on high profile alliances with
Internet search engines, portals and service

                                       34
<PAGE>

providers, we believe that a traditional media advertising strategy is an
essential component to establishing any consumer brand and especially an
Internet brand. Due to management's background, we are able to immediately
apply a traditional media branding philosophy to the Internet based service we
provide.

   The public relations activities coordinated through Fleishman-Hillard will
complement the advertising program and will likely include intensive media
relations support for the July relaunch of the website. This support will take
the form of an aggressive media outreach to the consumer and business press
with the goal of generating awareness of the website re-launch and brand
campaign.

Revenue Model

   We intend to leverage the growth in our consumer base by exploiting
opportunities to develop multiple revenue streams including
advertising/sponsorship, e-commerce/transaction and syndication of content and
interactive tools. In the first quarter of 1999, we launched a health products
shopping area at our website and we plan to continue to expand our
relationships with leading web e-tailers to offer consumers a full range of
health-related products and services. Unlike many of our competitors, we have
an opportunity to leverage our proprietary content and interactive tools
through syndication to provide an additional revenue stream. We also believe
that health consumers are interested in premium subscription offerings such as
personalized smoking cessation and dietary programs, personalized health and
condition reports and direct access to leading medical experts. By pursuing
diversified revenue opportunities, we seek to reduce our dependence on and
exposure to any single revenue stream.

Advertising/Sponsorship Sales

   Advertising on the Internet is rapidly becoming a viable commercial medium.
According to Jupiter Communications, advertising revenue on the Internet is
forecast to grow from $1.9 billion in 1998 to $4.4 billion in 2000 and $7.7
billion in 2002. We believe the demographics of our audience and our ability to
target specific users of our website are attractive to healthcare advertisers
and non-healthcare advertisers. We believe we have been able to create a
differentiated and productive advertising environment by providing the
following:

  . targeted programs to reach the most desirable consumers;

  . a wide variety and depth of sponsorship areas;

  . long-term exclusive relationships for highly prized condition-specific
    content;

  . creative, beyond-banner programs that appeal to more aggressive
    advertisers; and

  . personalization and key word targets that provide flexible cross-site
    delivery.

   We currently have over 50 different advertisers, five of which have signed
year-long commitment packages each ranging in total revenue to us from $150,000
to $400,000. A partial list of healthcare advertisers we have attracted
includes: Johnson & Johnson, AstraZeneca Pharmaceuticals, SmithKline Beecham,
Pfizer, Schering-Plough, Glaxo Wellcome, Eli Lilly, Merck, Hoffman LaRoche,
Butler Dental, Biogen, Hoechst Marion Roussel and SelfCare.

   Our consumer-oriented content also provides attractive audiences for non-
healthcare advertisers. In addition to covering a broad range of wellness
editorial (fitness, nutrition, stress reduction, pregnancy, childbirth, sexual
health, health for seniors, alternative medicine, herbs and vitamins), we are
developing a number of pre-packaged health-related sponsorship packages for
non-endemic advertisers in areas that could include healthy eating, healthy
travel, healthy pet, fiscally fit, auto safety, Y2K baby, fitness file and
holiday packages.

   A partial list of the non-healthcare advertisers we have attracted includes:
IBM, Citibank, Dr. Scholl's, Kellogg's, Ford, Talkway, Call Connect.com, GM
Buypower, GM Goodwrench, Pontiac, Buick LeSabre, Procter & Gamble, Infantime,
Women.com, Lifewise Family Financial Services, ESPN, Disney and Microsoft.

E-commerce

   Transactions. Our model for e-commerce is to generate revenue by focusing on
three areas: fees for guaranteed impressions, exclusivity fees and revenue
sharing. We believe our shopping channel has many advantages for the consumer,
including:

  . Information from our articles, databases, experts and community, all from
    one location, so that consumers can learn to manage their health and use
    that information to make better-informed purchases of products and
    services.

  . OnHealth TimeSavers enable consumers to read about, discuss and purchase
    various products. Every day, consumers can get information on timely
    subjects, share ideas with others and buy the products they need to help
    maintain their good health.

  . Carefully selected online retailers who offer the best combination of
    products and services, customer service, reliable and secure online
    transaction capability and competitive prices.

   We recently partnered with drugstore.com as our exclusive online drugstore,
VitaminShoppe as our exclusive vitamins and herbs merchant, and SelfCare as our
exclusive merchant in the Holistic Woman section. In addition to these partner
relationships, we have established various affiliate relationships. Under the
terms of the agreements governing affiliate relationships, we share in the
revenue from purchases made by consumers directed to the partner website from
our website. Affiliate merchants include Amazon.com, American Greeting Cards
Online, ProFlowers, Whole Foods Market, greenmarketplace.com and enews.com.

   In the near term, we anticipate that there will be approximately eight to
ten total categories in our shopping channel, all representing healthy living
extensions. Examples of additional categories to be added could include cooking
supplies, travel, healthy pets, insurance and music. We also plan to add an
assortment of gift baskets pertaining to health and life events, such as
sending a child to college or having a baby.

   Longer-term shopping channel plans include offering e-commerce products and
services that have an interconnection to our audience and subject matter,
through a combination of partnering with various e-commerce websites, as well
as developing or acquiring our own e-commerce offerings. Products are expected
to include medical/health-related supplies, everyday health and wellness
essentials, baby products, beauty products, home and garden, toys, music,
videos and financial services. We plan to continue to deepen the level and
types of services we offer based on consumer needs and requests, including
special commerce events, customized discounts on health products and more time-
saving buying opportunities focused on wellness and health management.

   We intend to introduce premium services in the fourth quarter of 1999.
Possible examples of paid subscription services include: Ask a Doctor, where
users can submit questions to a doctor for a fee; and smoking cessation, weight
loss, stress management and pre-natal care programs.

Syndication Opportunities

   We believe that our original content and interactive tools can be leveraged
into a broader revenue platform. Syndication of content and interactive tools
is a significant add-on revenue opportunity that arises naturally from our
strategy and branding program. Since we own a significant amount of our content
and interactive tools, we have the ability to syndicate content, interactive
tools and subsets of the website to other websites, offline media and/or
private label websites. We believe that syndication opportunities exist with
hospitals, pharmacy benefit management companies, corporations, health
maintenance organizations and associations, among others.

                                       36

Technology and Systems

   Our website uses Internet hardware and software technologies from, among
others, Compaq, Intergraph, F5 and Cisco, and software from Microsoft,
Netgravity and eShare. Exodus IT-class co-location facilities provide a secure,
high availability and high bandwidth environment for our production servers and
testing servers. Exodus provides redundant OC-3 and OC-12 backbone connections
to the Internet, uninterruptible power supplies with diesel generator backup,
housed in a copper-lined, earthquake-resistant building located in south
Seattle. Direct connections to the hosting facility via T1 and DSL lines allow
our main office to reliably connect to the production environment and the
Internet.

   All mission-critical database servers are designed to be redundant and
employ warm-backup technology to minimize downtime and maximize data integrity.
Multiple web servers and advertising servers are utilized to provide high-
availability. Traffic is balanced between all available servers through load
balancing, server monitoring hardware.

   We believe that onhealth.com has been designed to be a stable and scaleable
solution sufficient for our foreseeable needs. See "Risk Factors -- Our
business is dependent on the continuous, reliable and secure operation of our
website and related tools and functions we provide."

Competition

   The editorial environment in interactive media is new, highly competitive
and rapidly evolving. Since the Internet's commercialization in the mid 1990s,
the number of websites on the Internet competing for consumers' attention and
spending has proliferated with no substantial barriers to entry, and we expect
that competition will continue to intensify.

   Our website competes directly for advertisers, users, e-commerce customers
and merchants, distribution and syndication partners and other affiliates with
numerous Internet and non-Internet businesses, including:

  . health-related online services or websites targeted at consumers, such as
    accenthealth.com, ahn.com, americasdoctor.com, betterhealth.com,
    drkoop.com, drweil.com, healthcentral.com, healthgate.com,
    intelihealth.com, mayohealth.org, mediconsult.com, thriveonline.com and
    webmd.com;

  . online and Internet portal companies, such as America Online, Inc., Lycos
    Corporation, Microsoft Network, Excite, Inc., Infoseek Corporation, and
    Yahoo! Inc.;

  . electronic merchants and conventional retailers that provide healthcare
    goods and services competitive to those available from links on our
    website;

  . hospitals, HMOs, managed care organizations, insurance companies and
    other healthcare providers and payors which offer healthcare information
    through the Internet; and

  . other consumer affinity groups, such as the American Association of
    Retired Persons, SeniorNet and ThirdAge Media, Inc. which offer
    healthcare-related content to specific demographic groups.

   We believe that the principal competitive factors in attracting and
retaining users is the depth, breadth and timeliness of content, the ability to
offer compelling and relevant content and brand recognition. Other important
factors in attracting and retaining users include ease of use, service quality
and cost. In addition, we also compete with traditional media, including print
and television for users and advertising dollars. Our known and prospective
competitors are often significantly larger and better financed than us and may
be better able to afford a more intense competitive environment than OnHealth.
See "Risk Factors -- The Internet is highly competitive and changing rapidly,
and we may not have the resources to compete adequately."

                                       37

Intellectual Property

   We regard our copyrights, service marks, trademarks, trade secrets,
proprietary technology and similar intellectual property as critical to our
success, and we rely on trademarks, copyrights, and trade secrets to protect
our proprietary rights. While we try to assure that the quality of the OnHealth
brand is maintained through such actions, there can be no assurance that steps
we have taken and continue to take to protect our proprietary rights will be
adequate or that third parties will not infringe on our intellectual property.
In addition, there can be no assurance that third parties will not assert
infringement claims against us which, even if not meritorious, could result in
the expenditure of substantial resources and management effort. See "Risk
Factors -- Much of our website relies on owned or licensed intellectual
property and we cannot be sure that such rights are protected from the use of
others, including potential competitors."

Employees

   As of June 30, 1999, we employed 61 people on a full-time basis. When
conditions demand it, we also use part-time employees. None of our employees
are represented by a labor union and we consider our relationship with our
employees to be good. We believe that some measure of our future success is
dependent upon attracting and retaining qualified employees, and competition
for hiring such employees is intense.

Legal Proceedings

   From time to time, we have been involved in legal proceedings in the normal
course of our operations. Other than as described below, we are not currently a
party to any pending or, to our knowledge, threatened legal proceedings in
which an adverse decision could have a material impact on our results of
operations or financial position. In June 1999, Jon Fisse, our newly named
Chief Operating Officer resigned from the Company before the Company and Mr.
Fisse were able to agree on the terms of his employment agreement. We have
filed a declaratory judgement action in the United States District Court for
the Western District of Washington seeking to declare that Mr. Fisse terminated
his employment and that we owe him no future remuneration or stock option
benefits. On the same day Mr. Fisse filed a lawsuit in the United States
District Court for the Southern District of New York, asserting that OnHealth
terminated Mr. Fisse and violated his rights in connection with his separation
from OnHealth. As a result, Mr. Fisse is seeking damages which include
severance compensation, stock option benefits and compensatory and punitive
damages for allegedly defamatory statements contained in our press release
which announced Mr. Fisse's departure. We believe we have valid defenses
against Mr. Fisse's claims and intend to defend against such claims vigorously.

Facilities

   We lease approximately 7,000 square feet of space where our principal
executive and administrative offices are located at 808 Howell Street, Suite
400, Seattle, Washington 98101. The lease expires June 30, 2003. We also
maintain approximately 1,500 square feet of office space in Seattle that is
subleased on a month-to-month basis. In October 1998, we subleased
approximately 525 square feet of office space located at 420 Lexington Avenue,
Suite 300, New York, New York 10170. This sublease expires in September 1999.
Beginning September 1, 1999 we have leased 8,250 square feet of office space
located at 536 Broadway, New York, New York. This lease expires October 31,
2004.

                         Description of Our Securities
- --------------------------------------------------------------------------------

Common Stock

   Our Articles of Incorporation authorize us to issue 100,000,000 shares of
common stock and 1,000,000 shares of preferred stock. As of June 30, 1999,
there were 16,222,420 shares of common stock outstanding and no shares of
preferred stock outstanding. Each holder of a share of common stock gets one
vote per share on all matters submitted to a vote of shareholders but may not
cumulate votes for the election of directors. Holders of common stock also are
entitled to receive dividends as may be declared by the Board of Directors out
of funds legally available. In the event of our dissolution, liquidation or
winding up, holders of common stock are entitled to share in all assets which
remain after the satisfaction of any claims of creditors or of the holder of
any securities senior to the common stock. Holders of common stock have no
preemptive, subscription, redemption or conversion rights. All the outstanding
shares of common stock are fully paid and nonassessable.

Warrants

   As of June 30, 1999, we had outstanding warrants to purchase 224,662 shares
of common stock with various parties with varying exercise prices and
termination dates. Certain of these warrant holders have piggy-back
registration rights.

Provisions Affecting Acquisitions and Business Combinations

   The Washington Business Corporations Act contains certain provisions that
may have the effect of delaying or discouraging another person or company from
a hostile takeover of us. Chapter 23B.19 of the Washington Business
Corporations Act prohibits a target corporation, with certain exceptions, from
engaging in certain significant business transactions (such as a merger or sale
of assets) with a person or group of persons which beneficially acquires 10% or
more of the corporation's voting securities (an "Acquiring Entity") for a
period of five years after such acquisition, unless the transaction is approved
by a majority of the members of the target corporation's board of directors
prior to the date of the transaction. An Acquiring Entity is further prohibited
from engaging in significant business transactions with the target corporation
unless the per share consideration paid to holders of outstanding shares of
common stock and other classes of stock of the target corporation meet certain
minimum criteria. These provisions may have the effect of delaying, deterring
or preventing a change in control of the Company.

Director and Officer Indemnification

   The Washington Business Corporations Act provides that a Washington
corporation may include provisions in its articles of incorporation relieving
each of its directors of monetary liability arising out of his or her conduct
as a director for breach of his or her fiduciary duty, except liability for:
(i) acts or omissions of a director finally adjudged to be intentional
misconduct or a knowing violation of law, (ii) conduct in violation of Section
23B.08.310 of the Washington Business Act (which section relates to unlawful
distributions), or (iii) any transaction with respect to which it is finally
adjudged that a director personally received benefit in money, property or
services to which the director was not legally entitled. Our Articles of
Incorporation include such provisions. Our Articles of Incorporation and Bylaws
provide that we are obligated, to the fullest extent permitted by law, to
indemnify and advance expenses to each of our currently acting and former
directors and officers, and may so indemnify and advance expenses to each of
our current and former employees and agents. We believe that the foregoing
provisions are necessary to attract and retain qualified persons as directors
and officers.

    the rules of the SEC, shares not actually outstanding are nevertheless
    deemed to be beneficially owned by a person if such person has the right to
    acquire the shares within 60 days. Pursuant to such SEC rules, shares
    deemed beneficially owned by virtue of a person's right to acquire them are
    also treated as outstanding when calculating the percent of class owned by
    such person and when determining the percentage owned by a group.

                              Plan of Distribution
- --------------------------------------------------------------------------------

   We may offer and sell the shares covered by this prospectus from time to
time. We may sell the shares of common stock in one or more transactions in the
over-the-counter market, on the Nasdaq SmallCap Market or the Nasdaq National
Market or other exchange on which the shares may be listed, including through
block trades or ordinary broker's transactions, or in privately negotiated
transactions, through the writing of options on the shares or a combination of
such methods of sale, at fixed prices that may be changed, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices or at negotiated prices. Alternatively, we may offer the shares to or
through underwriters, brokers or dealers who may act solely as agents, or who
may acquire shares as principals. Such underwriters may include Warburg Dillon
Read LLC, SG Cowen Securities Corporation and CIBC World Markets Corp., among
others. We may pay usual and customary or specifically negotiated brokerage
fees or commissions in connection with such sales. In connection with such
sales, we and any participating brokers or dealers may be deemed "underwriters"
as such term is defined in the Securities Act and the commissions paid or
discounts allowed to any of such underwriters, brokers, dealers or agents, in
addition to any profits received on resale of the shares if any such
underwriters, brokers, dealers or agents should purchase any shares as a
principal, may be deemed to be underwriting discounts or commissions under the
Securities Act.

   If we use an underwriter or underwriters in the sale of common stock, we
will execute an underwriting agreement with the underwriter or underwriters at
the time we reach an agreement for sale. We will set forth in the prospectus
supplement the names of the specific managing underwriter or underwriters, as
well as any other underwriters, and the terms of the transactions, including
compensation of the underwriters and dealers. Underwriters and others
participating in any offering of common stock may engage in transactions that
stabilize, maintain or otherwise affect the price of the common stock. We will
describe any of these activities in the prospectus supplement.

   If a dealer is used in the sale of common stock, we or an underwriter will
sell common stock to the dealer, as principal. The dealer may then resell the
securities to the public at varying prices to be determined by the dealer at
the time of resale. The prospectus supplement will set forth the name of the
dealer and the terms of the transactions.

   We may indemnify any underwriter or broker-dealer that participates in
transactions involving the sale of the shares against liabilities resulting
therefrom. Among these liabilities for which indemnification may be provided
are those arising under the Securities Act. The prospectus supplement will
describe the terms and conditions of indemnification or contribution.

   We may be subject to the anti-manipulation rules of Regulation M under the
Exchange Act which apply to sales of shares in the market and to other
activities we may wish to conduct.

   In order to comply with the securities laws of certain states, if
applicable, the shares may only be sold in such jurisdictions through
registered or licensed brokers or dealers. In addition, in certain states the
shares may not be sold unless they have been registered or qualified for sale
in the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.

   In connection with distributions of the shares or otherwise, we may enter
into hedging transactions with broker-dealers or other financial institutions.
In connection with a hedging transaction, broker-dealers or other financial
institutions may engage in short sales of the shares in the course of hedging
the positions they assume with us. We may also sell the shares short and
deliver the shares offered hereby to close out such short positions. We may
also enter into option or other transactions with broker-dealers or other
financial institutions which require the delivery to such broker-dealer or
other financial institution of shares offered hereby, which shares such broker-
dealer or other financial institution may resell pursuant to this prospectus,
as supplemented or amended to reflect such

                                       43

transaction. We may also loan or pledge shares to a broker-dealer or other
financial institution, and, upon a default, such broker-dealer or other
financial institution may effect sales of the pledged shares pursuant to this
prospectus, as supplemented or amended to reflect such transaction. In
addition, any shares that qualify for sale pursuant to Rule 144 may, at the
option of the holder thereof, be sold under Rule 144 rather than pursuant to
this prospectus.

   We will make copies of this prospectus, with any supplements or amendments,
available to purchasers at or prior to the time of any sale of the shares
offered by this prospectus and the applicable prospectus supplement.

               Report of Ernst & Young LLP, Independent Auditors

The Board of Directors and Shareholders
OnHealth Network Company

   We have audited the accompanying balance sheets of OnHealth Network Company
as of December 31, 1997 and 1998 and the related statements of operations,
shareholders' equity and cash flows for each of the three years in the period
ended December 31, 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 OnHealth Network Company at
December 31, 1997 and 1998, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

                         Notes to Financial Statements
  (Information as of and for the six months ended June 30, 1999 is unaudited)

Note 1. Description of Business and Summary of Significant Accounting Policies

 Description of the Business

   OnHealth Network Company, formerly known as IVI Publishing, Inc. (the
"Company"), is engaged in a single business consisting of electronic publishing
of health and medical information in interactive multimedia formats.

 Interim Financial Information

   The unaudited interim financial information as of June 30, 1999 and for the
six months ended June 30, 1998 and 1999 includes all adjustments (consisting
only of normal recurring adjustments), which, in the opinion of management, are
necessary for a fair presentation of the interim information. 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.

 Use of Estimates

   The financial statements have been prepared in conformity with generally
accepted accounting principles, which require management to make estimates and
assumptions that affect the amounts and disclosures reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

 Fair Value of Financial Instruments

   Financial instruments of the Company consist of cash and cash equivalents,
accounts receivable, other current assets, accounts payable and other accrued
expenses. The Company's other financial instruments generally approximate their
fair values for all periods presented based on the short-term nature of these
instruments.

 Cash and Cash Equivalents

   The Company considers all highly liquid investments with a maturity of three
months or less at the time of purchase to be cash equivalents. For all periods
presented, cash and cash equivalents consisted principally of United States
Government obligations for which the carrying amount approximates fair value.

 Inventories

   All inventories are stated at the lower of cost (first-in, first-out method)
or market and consist of packaging supplies and finished goods.

 Furniture and Equipment

   Furniture and equipment are stated at cost and are depreciated using the
straight-line method over the shorter of the estimated useful lives of the
respective assets, generally five to seven years.

 Concentration of Credit Risk and Significant Customers

   The Company is potentially subject to a concentration of credit risk from
its trade accounts, which are not collateralized. The Company performs periodic
credit reviews of its customers and maintains reserves for potential losses for
uncollectible accounts. Such losses have historically been within management's
expectations.

represents 40% of the net revenue in 1998 was the result of a $603,000 payment
received from the customer related to minimum sales requirements from a
terminated CD-ROM distribution agreement. Two customers represented 77% and 27%
of accounts receivable at December 31, 1997. At December 31, 1998, two
customers comprised 36% and 20% of outstanding accounts receivable.

 Revenue Recognition

   The Company's revenue consists of fees for online services, product sales
and licensing revenue, contract development revenue, and fees relating to the
licensing of its content for use on cable television.

   Online revenue is generated through the sale of advertising and sponsorship
of the Company's onhealth.com website. Advertising and sponsorship revenue is
earned based upon the number of impressions delivered.

   Product sales and licensing revenue consists of retail distribution sales,
direct mail sales, and product sales and royalties on licenses to original
equipment manufacturers (OEM's). The revenue is recognized upon shipment of the
product or in accordance with the licensing agreements. An allowance for return
is recorded at the time revenue is recognized.

   Contract development revenue is generated through the use of the Company's
personnel and facilities for the creation of custom multimedia products. The
contract revenue is recognized on a percentage-of-completion basis or at a
specific hourly rate, depending on the terms of the contract.

   Revenue relating to the licensing of the Company's health and medical
content for use on cable television channels is recognized when payments are
received. The Company recognized revenue under its cable television agreement
with America's Health Network ("AHN") during 1996 and 1997. (See Note 12).

   Revenue for 1996, 1997 and 1998 and for the six months ended June 30, 1998
and 1999 are as follows (in thousands):

 Product Development, Editorial and Design Costs

   Product development, editorial and design costs consist principally of
payroll and related expenses for development, editorial, systems and
telecommunications operations personnel and consultants, systems and
telecommunications infrastructure and costs of acquired content. To date, all
product development, editorial and design costs have been expensed as incurred.

 Advertising Costs

   Advertising costs are expensed as they are incurred. Advertising costs in
1996, 1997, and 1998 were $556,000, $190,000 and $3,409,000, respectively.

 Income Taxes

   Income taxes are provided based on earnings reported for financial statement
purposes. Deferred income taxes are provided for temporary differences between
financial reporting and income tax basis of assets and liabilities under the
liability method.

 Stock Based Compensation

   Pursuant to Statement of Financial Accounting Standards ("SFAS") No. 123,
"Accounting for Stock-Based Compensation," the Company is required to disclose
the effects on the net loss and per share data as if the Company had elected to
use the fair value approach to account for all its employee stock-based
compensation plans. The Company follows the disclosure-only provisions of SFAS
No. 123 but applies Accounting Principles Board Opinion No. 25 "Accounting for
Stock Issued to Employees" (APB 25) and related interpretations in accounting
for its employee stock options. Under APB 25, when the exercise price of
employee stock options equals the market price of the underlying stock on the
date of grant, no compensation expense is recorded.

 Loss Per Common Share

   Basic earnings per share ("EPS") excludes any dilutive effects of common
stock equivalents--options, warrants and convertible securities--and is
computed by dividing income available to common shareholders by the weighted-
average number of common shares outstanding during the period. Diluted EPS is
computed by dividing net income available to common shareholders by the
weighted-average number of shares of common stock and common stock equivalents
outstanding.

   The effects of common stock equivalents are excluded from the computation
for all periods presented as their effects are anti-dilutive.

 Reclassifications

   Certain reclassifications have been made for consistent financial statement
presentation.

 Impact of Recently Issued or Adopted Accounting Standards

   SFAS No. 130, "Reporting Comprehensive Income," was issued in June 1997.
This Statement, adopted by the Company on January 1, 1998, establishes
standards for reporting and display of comprehensive income and its components
(revenues, expenses, gains and losses) in a full set of general-purpose
financial statements. This statement requires that all items that are required
to be recognized under accounting standards as components of comprehensive
income be reported in a financial statement that is displayed with the same
prominence as other financial statements. This statement does not affect the
results of operations or financial position of the Company. For the years ended
December 31, 1996, 1997 and 1998, the Company had no items that would have been
classified as other comprehensive income.

   SFAS No. 131, "Disclosures About Segments of an Enterprise and Related
Information," was issued in June 1997 and redefined how operating segments are
determined. SFAS No. 131 requires

                                      F-9
<PAGE>

                            OnHealth Network Company
                   Notes to Financial Statements (Continued)

disclosure of certain financial and descriptive information about a company's
operating segments. This statement was adopted by the Company on January 1,
1998. Provisions of this statement require annual disclosure in the year of
adoption and interim reporting for periods thereafter. This statement does not
affect the results of operations or financial position of the Company. The
Company operates in one principal business segment across domestic markets.

   SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities," was issued in June 1998 and establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. The statement is
effective for all fiscal years beginning after June 15, 2000. The impact of the
adoption of the provisions of this statement on the results of operations or
the financial position of the Company has not yet been determined.

   In March 1998, the Accounting Standards Executive Committee issued Statement
of Position 98-1 ("SOP 98-1"), "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use." SOP 98-1 requires all costs related to
the development of internal use software other than those incurred during the
application development stage to be expensed as incurred. Costs incurred during
the application development stage are required to be capitalized and amortized
over the estimated useful life of the software. SOP 98-1 is effective for the
Company's fiscal year ending December 31, 1999. Adoption is not expected to
have a material effect on the Company's financial statements as the Company's
policies are substantially in compliance with SOP 98-1.

Note 2. Liquidity

   The Company has experienced recurring losses from operations and has
generated an accumulated deficit from inception to December 31, 1998 of
approximately $89,515,000. At December 31, 1998, the Company had a working
capital deficiency of $1,158,000 and total shareholders' deficit of $301,000.
In January 1999, the Company completed a $14.3 million issuance of the
Company's common stock. The Company believes that its cash and cash
equivalents, including the $14.3 million received in January 1999 private
placement, will be sufficient to fund its operations through December 31, 1999.
Operations generated a negative cash flow during 1996, 1997 and 1998 and the
Company expects a significant use of cash in 1999 as it markets and expands its
website. Any material unforeseen increase in expenses or reductions in
projected revenue will likely require the Company to seek additional debt or
equity financing. If additional cash is required, the Company may need to
reduce its expenditures or curtail certain operations. There can be no
assurance that additional capital, on a debt or equity basis, will be found, or
if found that it will be on economically viable terms.

Note 4. Common Stock

   On October 30, 1998, the Company completed a $3,690,000 private placement
involving the issuance of 1,000,898 shares of common stock at $3.69 per share.
On December 14, 1998, the Company completed a $2,000,000 private placement
involving the issuance of 542,419 shares of common stock at $3.69 per share.
The shares of common stock issued on October 30, 1998 and December 14, 1998
were issued to two accredited investors. The terms of these issuances
potentially obligated the Company to issue additional shares of common stock
(depending on the future performance of the Company's common stock (the "Reset
Provisions")). Such Reset Provisions only relate to those shares purchased by
the two investors on October 30, 1998 and December 14, 1998. As of March 12,
1999, all of the shares of common stock subject to the Reset Provisions have
been sold and no such Reset Provisions apply to any of the Company's
outstanding common stock.

   In January 1999, the Company completed a $14.3 million private placement
which resulted in the issuance of 2,596,000 shares of the Company's common
stock at $5.50 per share.

Note 5. Convertible Subordinated Debentures

   In November 1996, the Company issued $3,500,000 of 9% Convertible
Subordinated Debentures ($3,325,000 net of debt issue costs). These debentures
were converted into common stock on

                                      F-11
<PAGE>

                            OnHealth Network Company
                   Notes to Financial Statements (Continued)

October 28, 1997 at a rate of $2.00 per share, resulting in the issuance of
1,750,000 shares of Common Stock. The original conversion price was $3.25 per
share. The excess of the fair value of the Common Stock issued over the fair
value of the shares issuable pursuant to the original conversion terms was
$2,229,000 and was recorded as an other expense at the date of conversion.

Note 6. Convertible Redeemable Preferred Stock

   In 1995, the Company issued 2,000 shares of 6% Series A Convertible
Redeemable Preferred Stock (the "6% Series A Preferred Stock") for $2,000,000
($1,845,000 net of brokerage expenses) to Davidson & Associates, Inc.
("Davidson"), a distributor of multimedia educational and entertainment
software. The 6% Series A Preferred Stock was converted into 1,000,000 shares
of the Company's common stock on October 30, 1997, at a rate of $2.00 per
share. The original conversion price was $11.21 per share. The excess of the
fair value of the Common Stock issued over the fair value of the shares
issuable pursuant to the original conversion terms was $2,875,000 and was
recorded as a deemed preferred dividend at the date of conversion. This deemed
dividend increased the net loss applicable to common shareholders in the
calculation of the 1997 net loss per share as shown in the statements of
operations.

   In April 1998, the Company issued 5,000 shares of the Company's 5% Series B
Convertible Redeemable Preferred Stock (the "Series B Preferred Stock") for
$5,000,000. The Series B Preferred Stock was convertible at various increasing
discount rates to the market value of the common stock. This discount
aggregated $702,000 and was recorded as preferred stock accretion over the
various periods of conversion. During 1998, 3,630 shares of the Series B
Preferred Stock were converted into 732,605 shares of the Company's common
stock and 1,470 of such preferred shares were redeemed. The excess of the
redemption price over the carrying value of the preferred shares redeemed was
$220,000 and was recorded as a preferred stock deemed dividend. The preferred
stock accretion and deemed dividend increased the net loss applicable to common
shareholders in the calculation of the 1998 net loss per share as shown in the
statements of operations.

Note 7. Stock Options and Warrants

   In December 1997, the Company's Board of Directors adopted the 1997 Stock
Option Plan ("1997 Plan") for its employees, directors and consultants. The
1997 Plan, which is administered by the Board of Directors, permits the Company
to grant stock options for the purchase of Common Stock. The purpose of the
1997 Stock Option Plan is to promote the success of the Company by facilitating
the employment and retention of competent personnel and by furnishing incentive
to directors, officers and employees of the Company and consultants and
advisors to the Company, upon whose efforts the success of the Company will
depend to a large degree. Incentive stock options ("ISOs") and non-qualified
stock options may be granted pursuant to the 1997 Plan.

   The Company also has a 1991 Stock Option Plan (the "1991 Plan") for its
employees. The 1991 Plan, which is administered by the Board of Directors,
permits the Company to grant stock options for the purchase of Common Stock.
The 1991 Plan provides for the granting of ISOs and non-qualified stock
options. In the case of ISOs, the exercise price must be at least equal to the
fair market value per share of the Common Stock on the date of grant. In the
case of non-qualified stock options, the exercise price must be at least 85% of
the fair market value per share on the date of grant. Options generally expire
nine to ten years from the date of grant.

   In addition, the Company has a Director Stock Option Plan pursuant to which
current non-employee directors are eligible to receive options to purchase
shares of the Company's common stock at the market price on the date of grant.

   From time to time, the Company's Board of Directors may grant stock options
outside of the existing stock option plans. In 1997, the Board of Directors
adopted the 1997-1998 New Hire Stock Option Plan. This plan provides for the
granting of 1,213,500 non-qualified stock options to newly hired employees in
late 1997 through early 1998. In 1997, the Company granted options to purchase
522,500 shares at prices ranging from $2.31 to $2.50 per share. These options
expire in 2007. In

1998, the Company granted options to purchase 996,000 shares at prices ranging
from $2.75 to $7.88 per share. These options expire in 2008. The options
granted under this plan had a weighted average price per share of $3.33. Of the
options granted in 1997 and 1998, 40,000 and 265,000 stock options,
respectively, were canceled in 1998 and none were exercised.

   The pro forma information regarding net loss and net loss per share required
by SFAS No. 123 has been determined as if the Company had accounted for its
employee stock options under the fair value method of SFAS No. 123. The fair
value for these options has been estimated at the date of grant using a Black-
Scholes option pricing model with the following weighted-average assumptions
for 1996, 1997 and 1998:

</TABLE>

   The weighted-average fair value of options granted during 1996, 1997 and
1998 was $2.99, $1.74, and $2.97, respectively. The Black-Scholes option
valuation model was developed for use in estimating the fair value of traded
options that have no vesting restrictions and are fully transferable. In
addition, option valuation models require the input of highly subjective
assumptions including the expected stock price volatility. Because the
Company's employee stock options have characteristics significantly different
from those of traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

   For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows:

   The pro forma effect on the net loss for 1996, 1997, and 1998 is not
representative of the pro forma effect on the net loss in future years because
it does not take into consideration pro forma compensation expense related to
grants made prior to 1995.

   As of December 31, 1997 and 1998 the Company had warrants outstanding to
purchase 547,260 and 678,577 shares of Common Stock at prices ranging from
$3.25 per share to $30.94 per share. Warrants outstanding at December 31, 1998
expire from 1999 through 2003. The warrants were generally issued to

Note 11. Income Taxes

   At December 31, 1998, the Company has net operating loss carryforwards of
$81,910,000 for income tax purposes and unused research and development credits
of $339,000 that expire at various times through 2013. These carryforwards are
subject to the limitations of Internal Revenue Code Section 382. This section
provides limitations on the availability of net operating losses to offset
current taxable income if significant ownership changes have occurred for
federal tax purposes. For financial reporting purposes, a valuation allowance
has been recognized to completely reserve for the deferred tax assets related
to those carryforwards. The reserve has been established because of the
uncertainty of future taxable income, which is necessary to realize the
benefits of the net operating loss carryforwards.

   Components of the Company's deferred tax assets and liabilities are as
follows:

Note 12. Investment in America's Health Network

   In March 1994, the Company acquired an equity position in America's Health
Network ("AHN"), a health information cable television network that combines
live programming with medical consumer product sales. The network launched on
March 25, 1996.

   In the first quarter of 1994, the Company expensed its entire investment of
$2,000,000 along with the related investment banking fees of approximately
$263,000. This approach to the investment was made on the basis that the
invested amounts are not assured of recoverability through future revenue
streams. As of December 31, 1998 and 1997, the Company's underlying equity in
its investment in AHN was approximately $100,000 and $500,000 based on
approximately 1% and 4% of AHN's net assets, respectively. However, because the
Company expensed its investment, its equity in AHN's net assets is not
recognized on the balance sheet.

   In May 1995, the Company entered into a content and royalty agreement with
AHN. Under the agreement the Company licensed its multimedia content to AHN
starting in May 1995 and was to receive minimum licensing royalties over the
life of the agreement. This revenue was being recognized evenly over the
expected life of the contract. Due to the gradual increase in actual payments
versus the straight-line revenue recognition policy, a receivable was recorded
for the difference between the revenue recognized and the cash received during
the early years of the contract. In June 1997, as a result of the Company not
receiving its quarterly payment, the outstanding AHN receivable was fully
reserved. Due to the uncertainty of future payments, the Company began
recognizing revenue on a cash basis. In December 1997 and in early 1998, AHN
made payments which were applied against the receivable. At December 31, 1998,
the Company has a fully reserved receivable of $153,000 and AHN had failed to
make three scheduled payments totaling $1,688,000. The Company recorded $0,
$493,000 and $1,972,000 in license royalty revenue in 1998, 1997 and 1996,
respectively.

Note 13. Agreement with AT&T

   In October 1995, the Company entered into a four year agreement with AT&T
whereby the Company agreed to provide content for AT&T's HealthSite, a division
of AT&T's Personal Online Service ("POS"), in exchange for guaranteed revenues.
In August 1996, AT&T discontinued the HealthSite, and subsequently discontinued
POS. The Company received the 1996 guaranteed revenue payment of $1,000,000

released from the Company's "right of first offer" on Mayo health products
produced for electronic media, and Mayo assumed operating expenses incurred for
the website retroactive to January 1, 1997 which were recorded as a reduction
to product development expenses. The Company recorded the $2,700,000 payment as
other income and recorded the $300,000 payment as contract development revenue
during the third and fourth quarters, respectively, of 1997.

Note 16. Related Party Transactions

   During 1996, 1997 and 1998, the Company subleased approximately 20,000
square feet of its Eden Prairie office space to Reality Interactive, Inc.
Reality Interactive, Inc. and the Company share a common Board member. The
lease was terminated in 1998.

   During 1996, two officers of the Company participated in the Company's debt
offering. The total amount of debt issued by the Company to these individuals
was $120,000. Additionally, three directors of the Company participated in the
debt offering, either individually or through affiliated organizations. The
total amount of debt issued by the Company to these individuals and
organizations was $550,000. On October 28, 1997, this debt was converted into
common stock at a rate of $2.00 per share (see "Note 5. Convertible
Subordinated Debentures").

Note 17. Legal Proceedings

   In February 1996, an action in the District Court of Hennepin County
(Minnesota) was brought by T. Randal Productions et al. against the Company and
one current and two former employees. The plaintiffs made various allegations,
including misappropriation of corporate opportunities and trade secrets by the
Company and its employees and sought award of monetary damages, exemplary
damages and royalties substantially in excess of $10.0 million. In November
1997, a jury found that there was no joint venture between T. Randal and the
company and/or any of its employees but awarded T. Randal $480,000 plus
interest for damages sustained to its business. Plaintiffs moved for a new
trial, amended findings and for judgment notwithstanding the verdict. The jury
verdict was upheld by the trial court. The plaintiffs appealed this decision to
the Minnesota Court of Appeals. In March 1999, the Minnesota Court of Appeals
affirmed the decision of the trial court. The Company believes the plaintiffs
will petition for a rehearing which Company counsel believes will not be
successful. The plaintiffs also have an action pending against certain
affiliates of the Company on the same grounds on which the action against the
Company was based. The Company has indemnified these affiliates against any
damages arising out of these claims. Counsel has advised the Company that the
jury verdict in the action against the Company should be controlling in this
action against the affiliates. As of December 31, 1998, the Company has accrued
$480,000 plus estimated court costs.

Note 18. Relocation of Operations

   During early 1998, the Company relocated its primary operating facilities
from Minneapolis, Minnesota to Seattle, Washington. As a result, certain of the
Company's Minnesota leasehold improvements and computer and software equipment
having a carrying value of $721,000 were not transferable or were not utilized
in the Company's Seattle operations. In 1997, the Company had estimated and
recorded the related relocation expense of $721,000 as a General and
Administrative expense. In addition, in 1997 the Company recorded $252,000 and
$610,000 in general and administrative expenses related to lease termination
costs and severance for former officers and employees, respectively.

Note 19. Subsequent Events (unaudited)

   On June 1, 1999, the Company made a payment of $950,000 to T. Randal
Productions in full satisfaction of a judgment against the Company.

                   Notes to Financial Statements (Continued)


   In June 1999, Jon Fisse, the Company's newly named Chief Operating Officer,
resigned from the Company before the Company and Mr. Fisse were able to agree
on the terms of his employment agreement. The Company has filed a declaratory
judgement action in the United States District Court for the Western District
of Washington seeking to declare that Mr. Fisse terminated his employment and
that it owes him no future remuneration or stock option benefits. On the same
day Mr. Fisse filed a lawsuit in the United States District Court for the
Southern District of New York, asserting that the Company terminated Mr. Fisse
and violated his rights in connection with his separation from the Company. As
a result, Mr. Fisse is seeking damages which include severance compensation,
stock option benefits and compensatory and punitive damages for allegedly
defamatory statements contained in a press release announcing Mr. Fisse's
departure. The Company believes it has valid defenses against Mr. Fisse's
claims and intends to defend against such claims vigorously. However, the
outcome of this lawsuit may have a material adverse effect on the Company's
financial position and results of operations.

   On June 15, 1999, the shareholders approved an increase in the number of
authorized shares of the Company's common stock to 100,000,000 from 29,000,000.
