                               HealthCentral.com

Our Business

   Our company provides online healthcare content and the ability to purchase
health-related products online, or e-commerce, to consumers through our
HealthCentral.com network, which consists of the following websites:

  . www.HealthCentral.com. HealthCentral.com is our flagship website that
    provides original, trustworthy, up-to-date and personalized online
    healthcare information to consumers. The cornerstone of HealthCentral.com
    is our relationship with Dr. Dean Edell, a widely recognized television
    and radio personality. Dr. Edell has a daily syndicated radio program,
    which is broadcast on over 300 radio stations, as well as a brief radio
    rush hour broadcast. We believe these two radio broadcasts combined reach
    an estimated 13 million listeners per week. Dr. Edell also has a
    syndicated television report broadcast in over 50 television markets. In
    September 1999, according to an audit completed by Nielsen I/PRO,
    www.healthcentral.com attracted approximately 5.3 million page views, and
    according to Double Click 781,542 unique users.

  . www.HealthCentralRx.com. HealthCentralRx.com is our online drug store,
    offering over 23,000 stock keeping units, or SKUs, a term used to
    describe distinct retail products. HealthCentralRx.com has fulfillment
    agreements with Bergen Brunswig, a major drug distributor, for health and
    beauty aids, over-the-counter products and prescription drug orders.
    HealthCentralRx.com is one of five health anchor tenants on the America
    Online HealthOnline Pharmacy Channel.

  . www.RxList.com. RxList.com is our online database of over 4,000
    pharmaceuticals and other medicines, with extensive information on 600
    entries. RxList.com has been developed and enhanced since 1995.
    RxList.com has direct links from over 10,000 websites and search engines
    seeking drug information. According to Nielsen I/PRO, www.RxList.com
    attracted approximately 2.8 million page views in September 1999, and,
    according to DoubleClick, 364,000 unique users in that same month.

   We intend to expand our HealthCentral.com network through additional
websites and relationships. We recently entered into an agreement with
AltaVista under which we will be the exclusive healthcare content provider to
its website, subject to conditions, and we expect to launch a co-branded health
channel in the first quarter of 2000. We recently launched
www.peoplespharmacy.healthcentral.com, featuring pharmacy-related content
provided exclusively by the authors of The People's Pharmacy, a newspaper
column published in over 150 newspapers. We also recently launched a co-branded
health channel with MediaLinx, a Canadian portal, which focuses on Canadian
health content.

   In addition, we act as an application service provider, which means that we
design, host and maintain websites for healthcare institutions. These websites
are private label websites, which means that they are branded under our
clients' own names and brands rather than ours. Some of our current clients
include Brown and Toland, Scripps Clinic, Sutter Health and Catholic Healthcare
West.

Our Market Opportunity

   The Internet has become an increasingly popular source of healthcare
information and products. Consumer research conducted by Cyber Dialogue in 1999
found that 24.8 million U.S. adults search for health information on the
Internet, with the number expected to grow to 30 million in the year 2000. The
explosive

                                       3
<PAGE>

growth in demand for online health information has been driven by consumers
seeking to make better informed personal healthcare decisions. Consumers are
also increasingly purchasing healthcare products on the Internet. Forrester
Research estimates that almost one third of a surveyed group of Internet users
shopped for health and personal care products online during the previous six
months. In addition, Jupiter Communications estimates that consumer purchases
of healthcare goods are expected to grow from $2.4 million in 1998 to $1.7
billion in 2003.

Our Business Model

   We believe we are strongly positioned to integrate a wide range of health-
related content with a complete healthcare e-commerce solution. Through our
HealthCentral.com network, we derive revenue from advertisements and
e-commerce. Through our institutional Internet services business, we derive
revenue from annual license fees for applications, content, hosting and
maintenance services, as well as from development fees for customization
services. For the nine month period ended September 30, 1999, we had net losses
of $9.1 million, and as of September 30, 1999 we had an accumulated deficit of
$9.6 million. Our goal is to become the consumer's most trusted and complete
online source of healthcare information and products.

Our Strategy

   Our business strategy incorporates the following key elements:

  . build our brands and drive network traffic by using cross-media
    exposure--in television, radio and print media-- through our
    relationships with established medical professionals in traditional media
    such as Dr. Dean Edell and Joe and Teresa Graedon, through our
    relationships with AltaVista, America Online and MediaLinx and through
    television, radio and newspaper advertising;

  . cultivate multiple revenue streams of sponsorship and advertising fees
    principally from our flagship HealthCentral.com website and our
    RxList.com website, e-commerce revenue from HealthCentralRx.com, and fees
    and licensing revenue from products and services that we provide to our
    institutional clients;

  . continue to add unique and compelling content to our HealthCentral.com
    network;

  . attract a growing base of customers to HealthCentralRx.com and provide
    them with a superior shopping experience by offering them a complete line
    of drug store products and useful links to content on HealthCentral.com,
    RxList.com and PeoplesPharmacy.HealthCentral.com;

  . increase users' return visits to our network through interactive
    features;

  . maintain and strengthen a relationship of trust with our users and
    consumers; and

  . leverage our existing strategic relationships with AltaVista, America
    Online and Bergen Brunswig, and pursue additional complementary
    relationships.

Recent Acquisitions

   In October 1999, we acquired ePills Inc., an online pharmacy company, and
RxList.com, Inc., an online pharmaceutical database company. We recently
changed the name of ePills to "HealthCentralRx.com, Inc." All references to our
online drug store in this prospectus have been changed to reflect the new name.

   Our principal executive offices are located at 6001 Shellmound Street, Suite
800, Emeryville, CA 94608. Our telephone number at that location is (510) 250-
2500. Information contained on the websites on the HealthCentral.com network,
including www.healthcentral.com, www.rxlist.com and www.healthcentralrx.com,
does not constitute part of this prospectus.

   "HealthCentral.com," "Windom Health," "HealthCentralRx.com," "RxList.com,"
"HealthView" and "LifeView" are our trademarks. We are in the process of filing
for federal trademark registrations for the trademarks "HealthCentral.com,"
"HealthCentralRx.com" and "Windom Health Enterprises." This prospectus also
makes reference to trademarks of other companies.

                                  RISK FACTORS

   You should carefully consider the following risks in addition to other
information in this prospectus before purchasing our common stock. The risks
and uncertainties described below are the ones we currently deem to be material
and that we believe are specific to our company, our industry and this
offering. If any of these or other risks actually occurs, the trading price of
our common stock could decline, and you may lose all or a part of your
investment.

 Risks Related to Our Business

We only launched our HealthCentral.com website in November 1998 and our
HealthCentralRx.com website in September 1999, which makes it difficult for
investors to evaluate an investment in our common stock.

   We have a limited operating history on which you can evaluate our business.
You should consider an investment in our stock in light of the risks, expenses
and difficulties frequently encountered by early stage companies in new and
rapidly evolving markets such as the Internet healthcare market. These
challenges include our ability to:

  .  attract and retain a large audience of users to our HealthCentral.com
     network;

  .  compete effectively against better-established Internet health
     companies, such as drkoop.com, drugstore.com and planetRx;

  .  gain advertising and sponsorship revenue from vendors of health-related
     products and services;

  .  implement a successful e-commerce strategy through our
     HealthCentralRx.com subsidiary;

  .  create and maintain successful strategic alliances with portals,
     provider groups, content providers and other third parties;

  .  develop our institutional Internet services business;

  .  develop and upgrade our technology; and

  .  attract, retain and motivate qualified personnel.

We had an accumulated deficit of $9.6 million at September 30, 1999 and expect
our expenses to increase, and thus we may never become profitable.

   We expect our operating expenses to substantially exceed revenues for the
foreseeable future, and we may never become profitable. Since our inception, we
have had very limited revenues and have incurred net losses in each year. While
we are unable to predict accurately our future operating expenses, we currently
expect these expenses to increase substantially, as we, among other things:

  .  make substantial payments to both our existing and future business
     partners to gain advertising revenue, traffic or otherwise expand our
     HealthCentral.com network;

  .  promote our HealthCentral brand;

  .  develop or acquire unique health-related content;

  .  hire additional employees;

  .  develop and expand our systems infrastructure and support functions; and

  .  offer product promotions.

A failure to build our brand names quickly and significantly will result in
lower than expected revenues.

   If we do not gain significant brand recognition quickly, we may lose the
opportunity to build a critical mass of customers and our business may fail.
Some of our competitors, such as drkoop.com, drugstore.com and

                                       7
<PAGE>

planetRx have much stronger name recognition than we do. The increasing
competition in our markets makes building a brand more expensive and difficult
than it otherwise would be. To increase brand recognition, we will need to
increase substantially our sales and marketing efforts, our third party
alliances, and our content, product and service offerings, all of which are
expensive.

   We intend to market our HealthCentralRx.com brand in conjunction with the
Good Neighbor Pharmacy service mark, which we have licensed from Bergen
Brunswig. However, there already exists a Good Neighbor Pharmacy website and
one or more of the 2,000 independent pharmacies in the Good Neighbor Pharmacy
Network may develop their own websites for the promotion of their own stores.
This possible proliferation of websites using the Good Neighbor Pharmacy mark
could cause confusion and dilute our HealthCentralRx.com brand.

We depend on Dr. Dean Edell to provide us with unique content and credibility,
and any failure by Dr. Edell to participate in our business could result in
reduced site traffic and revenues.

   We rely on Dr. Dean Edell, one of our co-founders, to provide unique content
for, and drive traffic to, our HealthCentral.com network. Dr. Edell is not
contractually obligated to provide content or drive traffic to our network, and
he is not compensated for such activity. If Dr. Edell ceased providing us with
content or ceased mentioning our HealthCentral.com network on his television
and radio shows, we would have to find a replacement for this unique content or
an alternative means of driving traffic to our site, both of which would be
difficult and expensive to do.

   In addition, under his agreement with Premiere Radio Networks, the
syndicator of his radio show, Dr. Edell has agreed not to authorize the use of
his name or likeness to promote any product or service in any way that would
conflict with his programs' advertisers or potential advertisers, or would
impair his credibility as a program host.

   Any diminishment in Dr. Edell's reputation as a medical expert and advisor,
his death or incapacity, the expiration of his 15 year agreement with us, or
any other development that would cause us to lose the benefits of our
affiliation with Dr. Edell could diminish our standing with healthcare
consumers as a credible source of healthcare information. Although we maintain
key person life insurance for Dr. Edell, his role in our company is
sufficiently critical that the insurance would not adequately protect us in the
event of his death. See "Business--Strategic Relationships."

We face substantial competition from better established companies, which could
result in our failure to gain needed market share.

   Over 15,000 healthcare websites compete with us for users, advertisers,
content and product providers, institutional clientele and other sources of
online revenue. We compete with other dedicated healthcare websites, such as
drkoop.com, OnHealth.com and DiscoveryHealth.com. In addition, we compete with
online portal companies, healthcare providers and payors and consumer affinity
groups. See "Business--Competition--HealthCentral.com and RxList.com."

   Through HealthCentralRx.com, we compete with:

  . other online drug stores, such as drugstore.com and planetRx,

  . pharmacy benefit managers, or PBMs, that sell pharmaceuticals directly,

  . traditional brick-and-mortar drug stores, including drug store chains,
    supermarkets, mass market retailers and independent drug stores, many of
    whom have begun or have announced their intention to offer online
    services, and

  . hospitals, HMOs and mail order prescription drug providers, many of whom
    are beginning to offer products and services over the Internet.

                                       8
<PAGE>

   Most of our current and potential competitors enjoy substantial competitive
advantages, such as:

  .  greater name recognition and larger marketing budgets and resources;

  .  established marketing relationships with manufacturers and advertisers;

  .  larger customer and user bases;

  .  substantially greater financial, technical and other resources; and

  .  larger production and technical staffs.

   We believe that we may face a significant competitive challenge from our
online competitors forming alliances with brick and mortar drug stores, HMOs,
PBMs or other competitors, which could both strengthen our competitors and/or
preclude us from entering into similar relationships with their partners. For
instance, drugstore.com has formed an alliance with RiteAid, and planetRx has
formed a strategic alliance with Express Scripts, Inc. Increased competition
could result in price reductions, fewer customer orders, reduced margins and
loss of, or failure to build, market share.

   In the market for institutional Internet services, we compete mainly with
payors' and providers' internal systems development teams, with local web
development companies, and with other consumer-oriented websites that are
selling applications to institutions, such as drkoop.com, Baby Center's CHI
division and WebMD. Healthcare participants may determine that our tools and
website development and maintenance services are inferior to those of our
competitors, that our product mix is inappropriate for their needs, or that it
would be better for them to independently develop and manage their own
websites. See "Business--Competition--Institutional Internet Services."

We need to generate substantial revenues from our e-commerce business for
healthcare products, this market is unproven, and we have limited experience in
it.

 The healthcare e-commerce market is unproven.

   Our rate of revenue growth could be significantly less than that of online
merchants in other industries because the online market for pharmaceutical and
other health products is in its infancy. This market is significantly less
developed than the online market for books, music, software, toys, auctions and
a number of other consumer products. Even if Internet usage and electronic
commerce continues to increase, the rate of growth, if any, of the online
pharmacy and health products market could be significantly less than the online
market for other products.

 Consumers may reject the concept of an online drug store in favor of a brick-
 and-mortar drug store.

   Historically, many pharmaceutical products have been sold through the
personal referral of a physician or pharmacist, and thus there is no
established business model for the sale of healthcare products or services over
the Internet. Specific factors that could prevent widespread customer
acceptance of our online drug store include:

  .  lack of coverage of customer prescriptions by, or additional steps
     required to obtain reimbursement from, insurance carriers or pharmacy
     benefit managers;

  .  lack of consumer awareness of our online drug store;

  .  longer delivery times for Internet orders, delays in responses to
     customer inquiries and/or difficulties in returning products, as
     compared to brick-and-mortar drug stores;

  .  shipping charges and problems related to shipping, such as product
     damage or failure to ship the correct order;

  .  lack of face-to-face interaction with a pharmacist;

                                       9
<PAGE>

  .  failure to meet shoppers' pricing expectations for prescription drugs,
     over-the-counter medicines and health and beauty products;

  .  customer concerns about security and privacy with regard to transmitting
     personal health information over the Internet; and

  .  inability to meet immediate delivery or pick-up requirements for
     prescriptions for acute conditions.

 We have limited experience in the healthcare e-commerce market.

   HealthCentralRx.com was only incorporated in January 1999 and only launched
its website in September 1999, and thus we have limited experience to date in
the sale of healthcare products and services online. We may need to expand the
breadth and depth of our product offerings, which would be both expensive and
time-consuming.

We are dependent on Bergen Brunswig and Medi-Mail for fulfillment of our orders
and access to pharmacy benefit managers.

   In July and September 1999, HealthCentralRx.com entered into a series of
agreements with Bergen Brunswig and its Medi-Mail subsidiary relating to the
fulfillment of orders placed on our HealthCentralRx.com website for healthcare
products and access to the PlusCare Provider Network of pharmacy benefit
managers, or PBMs. This fulfillment mechanism is complex and will require us to
develop reporting systems and integrate Bergen Brunswig's fulfillment systems
with our web-based systems. Developing and integrating operational systems is
technically difficult and may be delayed, which could delay our receipt of
revenues and diminish customer acceptance. In addition, there are many
important details regarding pricing, revenue sharing and operational procedures
which Bergen Brunswig and we have not yet finalized. Because Bergen Brunswig is
our exclusive fulfillment partner for some products, any failure by Bergen
Brunswig to supply sufficient quantities and types of products in a timely
manner could result in customer dissatisfaction and harm our e-commerce
business. In addition, these agreements expire in five years, and they may not
be renewed on favorable terms, or at all. If for any reason we could not renew
these agreements or enter into similar contractual arrangements with a licensed
pharmacy, we could not operate our online pharmacy business without becoming a
licensed pharmacy ourselves. This process is extremely expensive and difficult.
If the intended benefits are not realized from our relationship with Bergen
Brunswig, customer perceptions, revenues and our ability to execute our e-
commerce strategy may be jeopardized.

   Notwithstanding assurances from Bergen Brunswig regarding PBM access, Bergen
Brunswig may be subject to restrictions in the agreements with its individual
PBMs that are unknown to us. In addition, these contracts are typically subject
to periodic renewal, and thus we are subject to the risk of these contracts not
being renewed at all, or being renewed on terms that are not favorable to us.
Many PBMs are in the early stages of evaluating the impact of the Internet and
online pharmacies on their businesses. Thus, PBMs may determine in the future
to move business away from Medi-Mail for a variety of reasons, including
competitive reasons. As a result of these contractual and business
uncertainties, our revenue may be less than currently expected. In addition,
under our Medi-Mail agreement we bear the ultimate credit risk of collecting
from both consumers and payors. Finally, after the earlier of January 24, 1999
or ten days after the closing of this offering, Bergen Brunswig will be able to
enter into additional agreements with other online pharmacy companies and grant
them access rights to these PBMs, which could diminish any competitive
advantage we may have. See "Business--Strategic Relationships--Bergen
Brunswig."

Because we need to make substantial cash outlays and do not expect a
significant near-term improvement in our cash flows, we may need to raise
additional capital in the future and may not be able to raise it on acceptable
terms, or at all.

   We expect the proceeds of our initial public offering, together with
existing cash and cash equivalents to fund our operations for approximately 12
months. We do not expect a significant improvement in cash flows

                                       10
<PAGE>

from operations over this period and we need to make substantial investments in
our marketing and sales, our e-commerce capability and our technology and other
operations infrastructure. Moreover, we are contractually obligated to pay
AltaVista $31.5 million over the next two years, America Online $12.3 million
over the next two years, $3 million in connection with our acquisition of
RxList.com and $1.25 million in connection with our acquisition of
HealthCentralRx.com. In addition, we may enter into additional business
relationships that require us to make additional cash payments.

   The sale of additional equity or convertible debt securities could result in
dilution to our stockholders. Any debt securities issued could have rights
senior to holders of common stock and could contain covenants that would
restrict our operations. Any additional financing may not be available in
amounts or on terms acceptable to us, if at all.

We are obligated to pay AltaVista and America Online combined approximately
$48.6 million in cash and stock over the next two years, and if we do not
receive expected revenues from these relationships, our business could suffer.

   We have a three-year agreement with AltaVista to develop a co-branded health
channel and a two-year agreement with America Online under which our online
drug store will be one of five health-related anchor tenants on the America
Online HealthOnline Pharmacy Channel. Each of these agreements requires us to
make large payments over the respective terms of the agreements in exchange for
minimum numbers of user impressions--$65.6 million in cash and stock to
AltaVista over the three year term, and $12.3 million in cash to America Online
over the two year term. Either AltaVista or we may terminate the AltaVista
agreement after two years, in which case our total payment obligation over the
first two years would be $34.5 million in cash and stock, of which $1 million
has been paid. However, even if AltaVista delivers the minimum required
impressions, we may not generate revenues exceeding the payments due under the
contract because AltaVista retains all of the advertising revenues generated
from the co-branded channel. In addition, we may not generate traffic from the
co-branded channel to the HealthCentral.com website sufficient to justify our
expenses. If we do not receive the revenues we currently expect from these
relationships, or if either the AltaVista Health Channel or the America Online
HealthOnline Pharmacy Channel is unsuccessful in attracting traffic to our
websites or in enhancing our brands, these substantial investments may not be
recovered.

Any errors in filling or packaging the prescription drugs that Medi-Mail or the
Good Neighbor Pharmacy Network dispense on our behalf may expose us to
liability and negative publicity.

   Pharmacy errors relating to prescriptions, dosage and other aspects of the
medication dispensing process could produce liability for us. Pharmacists are
required by law to offer counseling, without additional charge, to their
customers about medication, dosage, delivery systems, common side effects and
other information they deem important. With HealthCentralRx.com's proposed mail
order delivery through Medi-Mail, this counseling is expected to be
accomplished by telephone access to pharmacists, but also in part through
inserts included with the prescription, which may increase the risk of
miscommunication because the customer is not personally present. We also plan
to post product information on our HealthCentralRx.com and RxList.com websites,
which creates additional potential for claims to be made against us. Our
insurance may not cover potential claims of this type or may not be adequate to
protect us from all liability that may be imposed.

   In the future, we expect that prescription orders placed on our
HealthCentralRx.com website may be picked up in person at a pharmacy in the
Good Neighbor Pharmacy Network, as well as filled by mail order through
Medi-Mail. We have limited control over Medi-Mail and no control over any of
the pharmacies in the Good Neighbor Pharmacy Network, and they may make errors.
Pharmacy errors either by Medi-Mail, one of the pharmacies in the Good Neighbor
Pharmacy Network or our competitors may produce significant adverse publicity
either for us or the entire online pharmacy industry. Because our
HealthCentralRx.com service mark will be displayed with the Good Neighbor
Pharmacy Network mark, any negligence by any of the pharmacies in the Good
Neighbor Pharmacy Network in filling orders or advising customers regarding
prescription drugs,

                                       11
<PAGE>

whether through HealthCentralRx.com or otherwise, could harm our reputation or
result in lawsuits, with or without merit, against us. The amount of negative
publicity that we or the online pharmacy industry may receive as a result of
pharmacy or prescription processing errors could be disproportionate in
relation to the negative publicity received by traditional pharmacies making
similar mistakes. We believe that any negative publicity could erode consumer
trust and result in an immediate reduction in product purchases.

We may be sued by consumers as a result of the health-related products we sell
through HealthCentralRx.com.

   Consumers may sue us if any of our products or services that are sold
through our website are defective, fail to perform properly or injure the user,
even if such goods and services are provided by unrelated third parties. We
have some contractual limits on our recourse against Bergen Brunswig in the
case of some product liability claims. Liability claims could require us to
spend significant time and money in litigation or to pay significant damages
and could seriously damage our reputation.

Extensive and changing government regulation of the healthcare and pharmacy
industries is expensive to comply with and exposes us to the risk of
substantial government penalties.

   Numerous state and federal laws regulate our health business covering areas
such as:

  .  the practice of medicine and other healing arts professions;

  .  the sale of controlled products such as pharmaceuticals and other
     healthcare products;

  .  prohibitions against the offer, payment or receipt of remuneration to
     induce referrals to entities providing healthcare services or goods;

  .  dispensing and delivering prescription, over-the-counter drugs and other
     medical products;

  .  advertising drugs, cosmetics and nutritional supplements;

  .  storage, transmission and disclosure of medical information and
     healthcare records; and

  .  state insurance regulations.

   Further, because the Internet health business is novel, federal and state
agencies may apply laws and regulations to us in unanticipated ways, and may
produce new legislation regulating our business, which could increase our costs
or reduce or eliminate certain of our activities or our revenues. See
"Business--Government Healthcare Regulation" and "Business--Other Governmental
Regulation."

In order to gain market share, we need to continue to provide unique content,
which is expensive and difficult to obtain.

   To attract and retain users to our HealthCentral.com network, we need to
continue to provide unique and informative content. We will need to purchase or
license much of this content from third persons. Competition for content from
people with the professional reputation, name recognition and expertise that we
require is intense and increasing. This competition may increase the fees
charged by high quality content providers, resulting in increased expenses for
us. We will not only have to expend significant funds to obtain and improve our
content, but we must also properly anticipate and respond to consumer
preferences for this content. If we are unable to enter into agreements for the
delivery of desirable content, or lose any existing agreements, it could delay
market acceptance of the HealthCentral.com network.

If consumers perceive our healthcare content to be influenced by our
relationships with advertisers or health-related product vendors, our
reputation could suffer.

   We receive sponsorship revenues from advertisers of health-related products
on our websites and revenues from sales of health-related products. However,
our success in attracting and retaining users to our websites

                                       12
<PAGE>

depends on our being a trusted source of independent health-related
information. There has been recent press attention focused on possible
conflicts of interest within the online healthcare information industry. Any
consumer perception that our editorial content is influenced by our commercial
relationships could harm our reputation and business.

We rely on relationships with other Internet companies, which are short-term or
non-exclusive, to drive traffic and build brand awareness.

   We have entered into agreements with third parties such as AskJeeves.com,
Broadcast.com, NetPulse Communications, Snap.com and Yahoo! to provide them
with content in exchange for either impressions or traffic. Many of our current
agreements are, or possible future agreements may be, short-term, non-exclusive
or may be terminated at the convenience of either party. We may be unable to
develop and maintain these relationships and generate sufficient traffic and
revenues from them. In addition, these third parties may never achieve market
acceptance themselves.

We face the risk of systems interruptions and capacity constraints on the
HealthCentral.com network, possibly resulting in adverse publicity, revenue
losses and erosion of customer trust.

   Any systems problems in the HealthCentral.com network, including our
HealthCentralRx.com online drug store, such as system disruptions, slower
system response times, and degradation in customer service levels, could result
in negative publicity, cause our users to use our competitors' services, and
reduce our revenues. Additionally, if we fail to meet the website performance
standards in our contracts with our institutional clients, they may terminate
their agreements, require refunds or fail to renew contracts with us, any of
which could decrease our institutional revenues.

   From time to time, we have experienced temporary system interruptions for a
variety of reasons, including power and telecommunications failures, flaws in
our software and greater than expected site traffic. We are also vulnerable to
breaches in our security and natural disasters. We may not be able to correct
any problem in a timely manner. Because we outsource the server hosting
function to a third party, some systems interruptions may be outside of our
control. We have no formal disaster recovery plan, and our insurance may not
adequately compensate us for losses that may occur due to systems
interruptions.

We depend significantly on our relationship with DoubleClick to generate
advertising revenues, and DoubleClick can terminate this relationship on short
notice.

   A significant portion of our revenues consists of the sale of advertising,
all of which is currently derived through our relationship with DoubleClick, an
online advertising sales agency. DoubleClick is our exclusive representative
for advertising sold on our HealthCentral.com website, except for limited non-
cash barter arrangements, if any; however DoubleClick can enter into
advertising sales contracts with our competitors, and either party can
terminate the contract on 90 days notice. We have no control over DoubleClick's
sales efforts, and if it fails to sell advertising in accordance with our
expectations, our revenues would likewise be lower. In addition, while we
anticipate that we may transition part or all of our advertising sales
activities to our own direct sales force over time, if DoubleClick were to
terminate our agreement before we completed a buildup in our direct sales
force, we would be forced to accelerate this process, which would be expensive
and difficult to do.

Our business model relies on developing and hosting websites for institutional
clients in the healthcare industry; this institutional market is new and
unproven and the institutions may not accept our Internet solutions.

   We expect to derive a substantial amount of our revenues from license and
development fees related to the designing, hosting and maintenance of private
label websites for our institutional clients. To date, the healthcare industry
has resisted adopting new information technology solutions. Healthcare payors
and providers may

                                       13
<PAGE>

determine that our solutions are too costly to implement or unnecessary to
manage their relationships with consumers. Moreover, these healthcare industry
participants may be unwilling to allow sensitive information to be stored in
our databases.

If the Internet does not prove to be an effective or profitable marketing media
for advertisers, especially those in the health industry, our business model
could fail.

 The Internet is a relatively new advertising medium.

   Our success depends on the increased use of the Internet as an advertising
medium. This advertising medium is unproven and may not become an effective
medium as compared to traditional advertising media. If the market for Internet
advertising fails to develop or develops more slowly than we anticipate, then
our ability to generate advertising revenue would be diminished. Various
pricing models are currently used to sell advertising on the Internet. It is
difficult to predict which, if any, will emerge as the industry standard,
thereby making it difficult to project our future advertising rates and
revenues. Widespread adoption of filter software, which limits or prevents
advertising from being delivered to an Internet user's computer, could
adversely affect the commercial viability of Internet advertising, which could
significantly impair our ability to generate revenues from advertising. See
also "--A failure to build our brand names quickly and significantly will
result in lower than expected revenues."

 Companies buying advertising for healthcare products over the Internet face
 special advertising issues.

   Health-related companies, which comprise our advertising and sponsorship
target market, face special problems with regard to Internet advertising.
Historically, these companies have marketed their products through physicians
and pharmacologists, and thus direct-to-consumer marketing, whether on the
Internet or in traditional media, is relatively new and unproven. In addition,
advertising and product claims of companies marketing or selling drugs and
cosmetics, including over-the-counter drugs and nutritional supplements, are
subject to regulation and enforcement by the FDA, FTC and similar state
agencies.

Our quarterly operating results are subject to significant fluctuations, and
our stock price may decline if we do not meet quarterly expectations of
investors and analysts.

   Our quarterly revenues and operating results are difficult to predict and
may fluctuate significantly from quarter to quarter as a result of a variety of
factors, including:

  .  shifts in user traffic levels on HealthCentral.com and
     HealthCentralRx.com and associated costs;

  .  shifts in the rate at which visitors to our HealthCentralRx.com website
     convert into customers;

  .  demand for our products and mix of products sold;

  .  shifts in the nature and amount of publicity about us or our
     competitors;

  .  changes in our pricing policies or the pricing policies of our
     competitors;

  .  changes in the frequency and size of repeat purchases by customers of
     our online drug store;

  .  shifts in our ability, and that of our fulfillment partners, Bergen
     Brunswig and Medi-Mail, to ensure sufficient product supply;

  .  seasonal patterns of spending by advertisers and sponsors and trends in
     advertising rates;

  .  long sales cycles and delays in website development for institutional
     projects;

  .  costs related to acquisitions of businesses or the timing of payments to
     our strategic partners;

  .  fluctuations in expected revenues from our strategic relationships;

                                       14
<PAGE>

  .  changes in reimbursement policies and practices of pharmacy benefit
     managers and insurance companies for prescription drugs;

  .  our technological capabilities to accommodate any future growth in our
     operations or customers; and

  .  changes in government regulation.

   If we do not meet the expectations of investors and analysts in any given
quarter, our stock price could decline.

Our recent growth has strained our existing personnel and other resources, and
any failure to manage this growth could increase our operating costs.

   We have experienced and are currently experiencing a period of significant
growth, which has placed, and will continue to place, a significant strain on
our resources. Any failure to successfully manage our growth could distract
management attention and result in our failure to execute on our business plan.
As a result of the acquisition of our online drug store, HealthCentralRx.com,
we have added over 13 new employees, and we will need to assimilate the
operations of HealthCentralRx.com into our operations. Our senior management
has no prior operational experience in the online drug store business. In order
to manage this growth effectively, we have to implement new transaction-
processing, operational, reporting, and financial systems, expand and train our
employee base, and maintain close coordination among our technical, finance,
marketing, sales and editorial staffs. We also need to devote significant
management time and financial resources to website and content development,
strategic relationships, technology infrastructure and operational
infrastructure.

Our management team is new, and we need these individuals to work together
effectively to manage our growth.

   Because we only began operating our HealthCentral.com website in November
1998, virtually our entire management team is relatively new. Our future
success depends on the successful integration of this management team and their
ability to work together effectively. Also, we need to successfully integrate
HealthCentralRx.com's employees into our existing team.

In order to execute our growth plan we must attract, retain and motivate highly
skilled employees, and we face significant competition from other Internet,
healthcare and new media companies in doing so.

   If we fail to attract new personnel or retain and motivate our current
personnel, our business and future growth prospects could be severely harmed.
We need to hire additional personnel in virtually all operational areas,
including sales and marketing, production, research and development, customer
service and administration. Competition for personnel throughout the Internet
and healthcare industries is intense. We have from time to time in the past
experienced, and we expect to continue to experience in the future, difficulty
in hiring and retaining highly skilled employees with appropriate
qualifications.

Lengthy sales cycles for our private label websites for healthcare institutions
could adversely affect our revenue growth.

   We expect that the sales process for our institutional web site development
business will be lengthy and will involve a significant business and technical
evaluation and possible commitment of capital and other resources by our
customers. The sales of our solutions are subject to delays due to our
customers' internal budgets and procedures for approving capital expenditures
and deploying new technologies within their networks.

If we are unable to acquire the necessary web domain names, our brands and
reputation could be damaged, and we could lose customers.

   We currently hold the Internet domain names healthcentral.com,
peoplespharmacy.healthcentral.com, healthcentralrx.com and rxlist.com. The
regulation of domain names in the United States and in foreign

                                       15
<PAGE>

countries is subject to change. Regulatory bodies could establish additional
top-level domains, appoint additional domain name registrars or modify the
requirements for holding domain names. As a result, we may not acquire or
maintain the healthcentral.com, peoplespharmacy.healthcentral.com,
healthcentralrx.com or rxlist.com domain names in all of the countries in which
we conduct business.

   The relationship between regulations governing domain names and laws
protecting trademarks and similar proprietary rights is unclear. Therefore, we
could be unable to prevent third parties from acquiring domain names that
infringe or otherwise decrease the value of our brands, trademarks and other
proprietary rights. In addition, we may be unable to prevent third parties from
acquiring and using domain names relating to our brands. We are currently in
the process of purchasing the domain names doctoredell.com and dredell.com from
a third party. Any confusion that may result from information on or related to
any websites with domain names relating to our brands could impair both our
ability to capitalize upon our brands and our marketing strategy.

We may not achieve the expected benefits of the acquisition of
HealthCentralRx.com, and the integration of HealthCentralRx.com may result in a
disruption to our business or the distraction of our management and employees.

   We may not be able to successfully assimilate the HealthCentralRx.com
personnel and operations or fund or accomplish the execution of this e-commerce
business plan. The integration of HealthCentralRx.com into our business may
strain our existing technology and operations systems as we attempt to
assimilate HealthCentralRx.com into our existing operations. In addition, key
HealthCentralRx.com personnel may decide not to work for us. These difficulties
could disrupt our ongoing business, distract our management and employees or
increase our expenses.

Any future acquisitions of companies or technologies may result in disruptions
to our business and/or the distraction of our management.

   To date we have completed acquisitions of three companies, Windom Health,
HealthCentralRx.com and RxList.com. We may acquire or make investments in other
complementary businesses and technologies in the future. We may not be able to
identify other future suitable acquisition or investment candidates, and even
if we do identify suitable candidates, we may not be able to make these
acquisitions or investments on commercially acceptable terms, or at all. If we
do acquire or invest in other companies, we may not be able to realize the
benefits we expected to achieve at the time of entering into the transaction.
In any future acquisitions we will likely face the same risks as discussed
above with respect to the integration of the business of HealthCentralRx.com.
Further, we may have to incur debt or issue equity securities to pay for any
future acquisitions or investments, the issuance of which could be dilutive to
our existing stockholders.

Breaches in our security and other unexpected problems could result in lawsuits
by customers and a violation of federal law.

   We retain confidential customer and patient information on our servers. Any
breach of security from a physical break-in, computer virus, programming error
or attack by a third party or an unexpected natural disaster could subject us
to a lawsuit. We may be required to expend significant sums to protect against
security breaches or to alleviate problems caused by breaches. In addition, a
breach of privacy of patient health records could constitute a violation of
federal law. We do not have full redundancy for all of our computer and
telecommunications facilities and do not maintain a back-up data facility.

Any failure to protect our intellectual property rights could impair our
ability to establish our brands.

   If we fail to adequately protect our proprietary rights in our content,
technology, products and services, our competitors could use the intellectual
property that we have developed to enhance their products and services, which
could harm our business. We rely on a combination of copyright and trademark
laws, trade secrets, confidentiality provisions and other contractual
provisions to protect our proprietary rights, but these

                                       16
<PAGE>

legal means afford only limited protection. Unauthorized parties may attempt to
copy aspects of our websites or to obtain and use information that we regard as
proprietary. We have applied for a U.S. trademark registration for
"HealthCentral.com," but we may be unable to secure this registration. In
addition, our competitors or others may adopt service names similar to ours,
thereby impeding our ability to build our brand identity and potentially
confusing consumers. We also rely on a variety of technologies that are
licensed from third parties, including our database and Internet server
software. These third-party licenses may not be available to us on commercially
reasonable terms in the future. See "Business--Intellectual Property Rights."

We may be sued by third parties for infringement of their proprietary rights.

   The healthcare and Internet industries are characterized by the existence of
a large number of patents and frequent litigation based on allegations of
patent infringement or other violations of intellectual property rights. As the
number of entrants into our market increases, the possibility of an
intellectual property claim against us grows. Our content, technology, products
and services may not be able to sustain any third party claims or rights
against their use. Some of the information in our RxList.com database regarding
drug descriptions, clinical pharmacology, indications and usage, warnings and
the like is copied from package inserts, which accompany the particular drug.
We have not obtained licenses to reproduce this information from the various
pharmaceutical companies. Although we have not received a copyright claim to
date, we could face potential copyright infringement claims in this regard. Any
intellectual property claims, with or without merit, could be time-consuming
and expensive to litigate or settle and could divert management attention from
administering our core business.

As a publisher of online content, we may have liability for information we
provide on, or which is accessed from, the HealthCentral.com network.

   Because users of our network and the websites of our institutional licensees
access health-related information, including with regard to possible adverse
reactions or side effects from medications or a particular medical condition
they may have, or may distribute our content to others, third parties may sue
us for various causes of action based on the nature and content of materials
that we publish. We could also become liable if confidential information is
disclosed inappropriately. These types of claims have been brought successfully
against online services in the past. Others could also sue us for the content
and services that are accessible from our network through links to other
websites or through content and materials that may be posted by our users in
chat rooms or bulletin boards, none of which we edit.

   Any indemnification provisions that we may have in agreements may not be
adequate to protect us. Our insurance may not adequately protect us against
these types of claims. Further, our business is based on establishing the
HealthCentral.com network as a trustworthy and dependable provider of health
care information and services. Allegations of impropriety, even if unfounded,
could therefore harm our reputation and business.

Our business could be harmed if the software, computer technology and other
systems we use are not year 2000 compliant.

   Any failure of either our material systems or the systems of our vendors or
business partners, or other systems, such as those of telecommunications
companies or financial institutions or the Internet, to be able to distinguish
between twentieth century dates and twenty-first century dates could disrupt
our operations. Possible consequences of year 2000 problems include
difficulties in operating our websites effectively, protecting the
confidentiality of patient records on our servers, conducting our e-commerce
business or conducting other fundamental parts of our business. Our reasonably
likely worst-case scenario would be the failure of the application server
software that facilitates the business logic for our e-commerce business, which
would disrupt our e-commerce business until the server could be replaced. We
have not developed a contingency plan to

                                       17
<PAGE>

address situations that may result if we or our vendors are unable to achieve
year 2000 compliance, and do not intend to develop a contingency plan.

   We do not know whether external communications, content feeds and systems
outside of our direct control will function properly, and the success of our
business, and of our e-commerce strategy in particular, significantly depends
on the year 2000 compliance of the computer systems and financial services used
by consumers. A significant disruption in the ability of consumers to reliably
access the Internet or portions of it or to use their credit cards would have a
negative impact on the demand for our products and services and reduce our
revenues. Additionally, we have warranted in several of our contracts with our
institutional customers that our software, computer technology and other
services are year 2000 compliant. To the extent that we breach these
warranties, we may face significant liability under these contracts. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Compliance."

Our executive officers and directors own a large percentage of our voting stock
and could delay or prevent a change in our corporate control or other matters
requiring stockholder approval, even if favored by our other stockholders.

   Immediately after this offering, our executive officers and directors, and
their respective affiliates, will continue to own approximately 42.8% of our
outstanding common stock. Accordingly, these stockholders may, as a practical
matter, be able to exert significant influence over matters requiring approval
by our stockholders, including the election of directors and the approval of
mergers or other business combinations. This concentration could have the
effect of delaying or preventing a change in control that other shareholders
view as favorable.

It may be difficult for a third party to acquire us even if doing so would be
beneficial to our stockholders.

   Provisions of our certificate of incorporation, bylaws and Delaware law may
discourage, delay or prevent a merger or acquisition that a stockholder may
consider favorable. See "Management--Board Composition" and "Description of
Capital Stock--Delaware Anti-Takeover Law and Provisions of our Certificate of
Incorporation and Bylaws."

 Risks Related to Our Industry

The success of our business model is dependent on continued growth and
acceptance of the Internet and growth of the online market for healthcare
information, products and services.

   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 and sponsorships designed to reach those consumers. Our
business model also assumes that those consumers will purchase health-related
products online using our website and that healthcare organizations and other
Internet healthcare companies will partner with us to reach these consumers.
This business model is not yet proven and may not be successful. Our future
revenues and profits, if any, substantially depend upon the widespread
acceptance and use of the Internet as an important channel for the delivery of
healthcare information, products and services. The Internet may not prove to be
a viable commercial medium due to inadequate development of a reliable network,
delays in development of high speed modems, or delays in the adoption of new
standards required to handle increased levels of Internet activity.

If we do not respond to rapid technological changes affecting the Internet
healthcare industry, our products and services could become obsolete.

   Any failure to respond to technological advances and emerging industry
standards could impair our ability to attract and retain customers. As the
Internet and online commerce industry evolve, we must address the increasingly
sophisticated and varied needs of our prospective customers and respond to
technological advances

                                       18
<PAGE>

and emerging industry standards and practices on a cost-effective and timely
basis. We may not be able to successfully implement new technologies or adapt
our network, proprietary technology and transaction-processing systems to
customer requirements or emerging industry standards.

Governmental regulation of the Internet could increase our operating costs.

   We receive confidential medical and credit card information from our
customers and website visitors. Laws and regulations directly applicable to
communications or commerce over the Internet are becoming more prevalent, and
compliance with any new laws could increase our operating expenses. In
particular, many government agencies and consumers are focused on the privacy
and security of medical and pharmaceutical records. The law of the Internet,
however, remains largely unsettled, even in areas where there has been some
legislative action. The rapid growth and development of the market for online
commerce may prompt calls for more stringent consumer protection laws, both in
the United States and abroad, that may impose additional burdens on companies
conducting business online and, in particular, on companies that maintain
medical or pharmaceutical records.

   A number of proposals have been made to impose additional taxes on the sale
of goods through the Internet. Taxation of online commerce could impair the
growth of our e-commerce business and add to the complexity of our transaction
processing system. See "Business--Other Governmental Regulation."

The health industry is extremely dynamic and constantly changing, and thus our
business may be affected by pricing pressures and healthcare reform
initiatives.

   The pressures of cost management, consumer demand for quality and safety and
professional concern about consumer reliance on non-professional advice will
dominate the healthcare marketplace for the foreseeable future. Any efforts to
contain costs by managed care entities will place downward pressures on gross
margins from sales of prescription drugs and other over-the-counter healthcare
products. Healthcare reform initiatives may further impact our prescription
drug sales. Any company in the health business is subject to the risk of an
extremely changeable marketplace, which could result in our need to continually
modify our business model, which could harm our business.

 Risks Related to this Offering

Management has broad discretion over how the proceeds of this offering will be
used.

   Our management will have broad discretion with respect to the use of the net
proceeds from this offering. Presently, anticipated uses of the proceeds of
this offering and our existing cash balances include making cash payments of
$31.5 million over the next two years to AltaVista, $12.3 million over the next
two years to America Online, $3 million in connection with our acquisition of
RxList.com and $1.25 million in connection with our acquisition of
HealthCentralRx.com, and funding working capital, sales and marketing, website
and content development, infrastructure improvements, operating losses, and
potential acquisitions and strategic alliances. We have not yet determined the
allocation of net proceeds and our existing cash balances among the foregoing
purposes.

The market prices of Internet-related companies have been extremely volatile,
and an active trading market for our stock may not develop or be sustained.

   Recent initial public offerings by Internet companies have in many cases
been accompanied by exceptional share price and trading volume changes in the
first days and weeks after the securities were released for public trading. In
addition, if an active trading market does not develop, investors may have
difficulty selling shares of our stock at a desirable price, or at all.
Investors may not be able to resell their shares at or above the initial public
offering price. In the past, securities class action litigation has often been
brought against a company

                                       19
<PAGE>

after a period of volatility in the market price of its stock. Any securities
litigation claims brought against us could result in substantial expense and
the diversion of management's attention from our core business.

New investors will suffer immediate and substantial dilution in the tangible
net book value of their shares.

   We expect the initial public offering price will be substantially higher
than the net tangible book value per share of the common stock. As a result,
investors purchasing common stock in this offering will incur immediate
substantial dilution. The net tangible book value of a share of common stock
purchased at the assumed initial public offering price of $10.00 per share will
be only $3.69. In addition, we have issued options and warrants to acquire
common stock at prices significantly below the initial public offering price,
which will result in additional dilution when and if they are exercised.

Future sales of shares by existing stockholders could affect our stock price.

   If our stockholders sell substantial amounts of our common stock in the
public market following this offering, the market price of our common stock
could fall, potentially resulting in substantial losses to investors. Such
sales also might make it more difficult for us to sell equity or equity-related
securities in the future at a time and price that we deem appropriate. See
"Shares Eligible for Future Sale."

Some shares in this offering may have been offered in violation of the
Securities Act of 1933, which could give purchasers of these shares the right
to seek refunds or damages.

   Prior to the effectiveness of our registration statement for this offering,
Lehman Brothers sent a letter and other written materials, accompanied by a
preliminary prospectus, to approximately 114 employees, consultants and
directors of HealthCentral.com whom we had designated as potential purchasers
of up to 90,900 shares of common stock in a directed share program in
connection with this offering. We then sent a follow-up email to this group of
people regarding the directed share program, which did not contain a legend
delineated under Rule 134 of the Securities Act, and which thus may have
constituted a prospectus that does not meet the requirements of the Securities
Act. If this follow-up email did constitute a violation of the Securities Act
of 1933, the recipients of the email who purchased common stock in this
offering could have the right, for a period of one year from the date of their
purchase of common stock, to obtain recovery of the consideration paid in
connection with their purchase of common stock or, if they already sold the
stock, sue us for damages resulting from their purchase of common stock. These
refunds or damages could total up to $1 million, based on an assumed public
offering price of $11.00 per share, if the investors suffer a total loss of
their investment during this period and seek refunds or damages. If this were
to occur, our results of operations and cash position could suffer.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

   Some of the statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business" and elsewhere in this prospectus are forward-looking
statements. These statements relate to future events or our future financial
performance, and involve known and unknown risks, uncertainties and other
factors that may cause our or our industry's actual results, levels of
activity, performance or achievements to be materially different from any
future results, levels of activity, performance or achievements expressed or
implied by these forward-looking statements. Such factors include those listed
under "Risk Factors" in this prospectus.

   In some cases, you can identify forward-looking statements by words such as
"may," "will," "should," "expects," "plans," "anticipates," "believes,"
"estimates," "predicts," "potential" or "continue," or the negative of these
and other similar words.

   Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements.

                                USE OF PROCEEDS

   Our net proceeds from the sale of the 7,500,000 shares of common stock we
are offering are estimated to be $68.3 million, or $78.7 million if the
underwriters' over-allotment option is exercised in full, assuming an offering
price of $10.00 per share, after deducting the estimated underwriting discount
and commissions and the estimated offering expenses.

   We currently expect to use the net proceeds of this offering, along with our
existing cash balances, primarily to fund working capital and sales and
marketing, to make cash payments of $31.5 million over the next two years to
AltaVista, $12.3 million over the next two years to America Online, $3 million
in connection with our acquisition of RxList.com and $1.25 million in
connection with our acquisition of HealthCentralRx.com, and to fund website and
content development, infrastructure improvements and operating losses. In
addition, we may use a portion of the net proceeds for complementary
acquisitions of products, technologies and businesses, although we have no
present plans, commitments or agreements to make any major acquisitions. The
amount of cash that we actually expend for working capital purposes will vary
significantly depending on a number of factors, including future revenue
growth, if any, and the amount of cash, if any, we generate from operations. We
have not yet prepared a quantified business plan. Thus, we have not yet
specified the allocation of net proceeds and our existing cash balances among
the foregoing purposes. Thus, management will have significant discretion in
applying the net proceeds of this offering. Pending the uses described above,
we will invest the net proceeds in short-term, investment grade, interest-
bearing securities.

                                DIVIDEND POLICY

   We have never paid dividends on our common stock or preferred stock. We
currently intend to retain any future earnings to fund the development of our
business. Therefore, we do not currently anticipate paying any cash dividends
in the foreseeable future.

                                    DILUTION

   The pro forma net tangible book value per share of our common stock at
September 30, 1999 was $0.92. Pro forma net tangible book value per share
represents total pro forma tangible assets less liabilities, divided by pro
forma common shares outstanding. Pro forma net tangible book value reflects the
actual net tangible book value of the Company at September 30, 1999, and
includes the pro forma effects of the following events:

  . the automatic conversion of all outstanding shares of preferred stock
    into 5,050,955 shares of common stock;

  . 1,579,065 shares of common stock valued at $9.07 per share, of which
    86,969 shares were reserved for issuance pursuant to the assumption of
    options, issued to shareholders of HealthCentralRx.com in connection with
    our acquisition of HealthCentralRx.com in October 1999; and

  . 836,422 shares of common stock valued at $10.00 per share issued in
    connection with our acquisition of RxList.com in October 1999 and a total
    of $2.6 million in notes payable issued to shareholders of RxList.com.

   After giving effect to our sale of shares of common stock in this offering
and after deducting the estimated underwriting discounts and commissions and
our estimated offering expenses, our pro forma net tangible book value as of
September 30, 1999 would have been $81.8 million, or $3.69 per share. This
represents an immediate increase in pro forma net tangible book value of $2.77
per share to existing stockholders and an immediate dilution of $6.31 per share
to new investors. Dilution in pro forma net tangible book value per share
represents the difference between the amount per share paid by purchasers of
shares of our common stock in this offering and the pro forma net tangible book
value per share of our common stock immediately following this offering. The
following table illustrates this per share dilution:

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

   The following discussion and analysis should be read in conjunction with the
financial statements and related notes included elsewhere in this prospectus.
In addition to historical information, the discussion in this prospectus
contains certain forward-looking statements that involve risks and
uncertainties. HealthCentral.com's actual results could differ materially from
those anticipated by these forward looking statements due to factors discussed
under "Risk Factors," "Business" and elsewhere in this prospectus.

Overview

   HealthCentral.com was co-founded by Dr. Dean S. Edell and James J. Hornthal
in August 1996, and, beginning in July 1998, was primarily involved in capital
raising activities and recruiting management personnel. In August 1998,
HealthCentral.com and Windom Health, a company providing website development
and consulting services to healthcare institutions, entered into a License and
Management Agreement under which HealthCentral.com took over the daily
management of Windom Health and undertook the development of the
HealthCentral.com website. The website was based largely on Windom Health's
software architecture and was launched in November 1998. Since the launch of
the website, we have focused on refining the technological architecture of the
HealthCentral.com website, developing programs and content to market the
HealthCentral.com brand name and attract users to the network, recruiting
personnel and raising capital. In August 1999, we acquired Windom Health, and
in October 1999 we acquired HealthCentralRx.com, our online drug store, and
RxList.com, an online pharmaceutical database company.

   We have historically derived revenues from advertising activities consisting
of short-term banner advertisements. As of September 30, 1999 we had not
entered into any barter arrangements. We record advertising revenues in the
period the advertising impressions are delivered to customers. We currently use
an outside vendor, DoubleClick, to solicit potential advertisers, to serve the
ads to our website and to bill and collect for these services. This outside
vendor provides monthly reports indicating impressions delivered, the amount
billed for our advertising services and the related administrative fee. The
Company records advertising revenues, as reported by the outside vendor, net of
this administrative fee because we bear no collection risk for the gross amount
of the advertising fees. The Company's advertising contracts do not guarantee a
minimum number of impressions to be delivered.

   In the future, we intend to go beyond traditional banner advertising
arrangements and enter into sponsorship agreements in which we will provide our
customers with enhanced promotional opportunities, exclusivity arrangements and
the design of customized co-branded web pages. We expect to recognize
sponsorship revenues ratably over the term of the sponsorship agreement. We
expect that costs incurred in connection with sponsorship agreements will be
included in production, content and product development expense.

   We also act as an application service provider, which means that we design,
host and maintain private label websites for healthcare institutions. Revenues
derived from our application service contracts principally consist of license
fees for website development applications, consulting fees from custom website
development and hosting, and website maintenance fees. Our license, hosting and
maintenance fees are recognized ratably over the term of the license, generally
between 12 and 24 months. For consulting projects, revenues are recognized at
the time services are rendered based on charges for time and materials.

   In order to implement our e-commerce strategy, we acquired
HealthCentralRx.com in October 1999. In July and September 1999,
HealthCentralRx.com entered into a series of agreements with Bergen Brunswig
and its Medi-Mail subsidiary. These agreements include various arrangements
relating to the fulfillment of orders placed on our website for healthcare
products as well as access to the PlusCare Provider Network of pharmacy benefit
managers. Under these agreements, Bergen Brunswig will be our exclusive
fulfillment provider for over-the-counter and health and beauty aid products
and Medi-Mail will be our exclusive fulfillment provider for most prescription
drug orders. These types of arrangements are complex and many important details

                                       26
<PAGE>

regarding pricing, revenue sharing and operational procedures have not yet been
finalized. Once these detail arrangements have been completed, we expect to
recognize revenues from product sales for over-the-counter and health and
beauty aid products, net of discounts, when products are shipped to customers.
Further, we expect to recognize commissions for the use of our website from
sales made by Medi-Mail for all prescription drugs. In both instances, however,
we will retain the ultimate credit risk for all sales made by Bergen Brunswig
and Medi-Mail.

   HealthCentral.com incurred net losses of $1,000 in 1997, $446,000 in 1998
and $9.1 million for the nine months ended September 30, 1999. We anticipate
that we will incur additional operating losses for the foreseeable future.

Recent Events

   In September 1999, we entered into a three-year agreement with AltaVista to
develop a co-branded health channel. The agreement provides that, in exchange
for a minimum number of user impressions on the co-branded health channel, we
are obligated to pay AltaVista approximately $65.6 million in cash and stock
over the three-year term of the agreement; however, either AltaVista or we may
terminate the relationship after two years, in which case the aggregate payment
obligation over the first two years in cash and stock would be $34.5 million,
of which $1 million has already been paid. In addition, if AltaVista meets
given performance thresholds based on the number of impressions delivered in
excess of guaranteed minimum amounts, we will issue to AltaVista warrants to
purchase shares of common stock, with the number of shares depending on the
amount by which AltaVista exceeds the thresholds. These warrants will have
varying exercise prices. The fair value of any warrants earned will be measured
on the date the performance commitment is met in accordance with Emerging
Issues Task Force Issue No. 96-18 "Accounting for Equity Instruments that are
Issued to Other than Employees for Acquiring, or in Conjunction with Selling,
Goods or Services," and the warrants will be valued using the Black-Scholes
option pricing model in accordance with Statement of Financial Accounting
Standards No.123, "Accounting for Stock-Based Compensation." The fair value of
the warrants will be expensed immediately and included in sales and marketing
expense.

   In September 1999, we entered into a four year agreement with The People's
Pharmacy to operate a co-branded website. We are entitled to all advertising
revenues from the co-branded website in exchange for a cash payment of $50,000
per annum. We also granted options to purchase up to 250,000 shares of common
stock to the principals of The People's Pharmacy.

   In October 1999, we acquired HealthCentralRx.com in exchange for 1,579,065
shares of common stock, including 86,969 shares reserved for issuance pursuant
to the assumption of options held by HealthCentralRx.com stockholders, and the
assumption of liabilities, representing a total purchase price of approximately
$15.9 million. This acquisition was accounted for using the purchase method of
accounting. We recorded intangibles and goodwill of approximately $14.5
million, which will be amortized on a straight line basis over two to three
years. We also recorded a charge for acquired in-process research and
development of $250,000.

   In October 1999, we acquired RxList.com in exchange for 836,422 shares of
common stock and a total of $2.6 million in notes payable to the RxList.com
shareholders discounted at a deemed interest rate of 10% over 6 months,
representing a total purchase price of approximately $11 million. This
acquisition was accounted for using the purchase method of accounting. We
recorded intangibles and goodwill of approximately $11.3 million which will be
amortized on a straight line basis over two to three years.

Results of Operations

 Nine Months Ended September 30, 1999 and 1998

   Revenues. Revenues consist of advertising revenues from short-term banner
advertisements and institutional sales revenues derived from designing, hosting
and maintaining private label websites for healthcare institutions. Our total
revenues were $489,000 for the nine months ended September 30, 1999, consisting
of $408,000 in advertising revenues and $80,000 in institutional sales
revenues. We had nominal revenues during the nine months ended September 30,
1998.

                                       27

   Production, Content and Product Development. Production, content and product
development expenses consist primarily of personnel costs for our engineering
and production personnel, expenditures related to editorial content, payments
to editorial consultants, server maintenance costs, and software development
and operations expenses. Production, content and product development expenses
increased to $1.8 million for the nine months ended September 30, 1999 from
$43,000 for the nine months ended September 30, 1998, primarily as a result of
$1.3 million in production and engineering staff costs and $275,000 of
amortization expense related to a warrant issued in connection with a content
licensing agreement. We expect our production, content and product development
expenses to increase substantially in the future as we enhance our websites and
develop and license additional content.

   Sales and Marketing. Sales and marketing expenses consist primarily of
related personnel costs. Sales and marketing expenses were $1.6 million for the
nine months ended September 30, 1999, primarily attributable to $1.2 million in
advertising and public relations expenses and $200,000 in sales personnel
costs. We had nominal sales and marketing expenses during the nine months ended
September 30, 1998. We expect that sales and marketing expenses will increase
in absolute dollars for the foreseeable future, as we increase expenditures for
branding, promotion and marketing, enter into new promotional agreements, and
expand our sales and marketing staff.

   General and Administrative. General and administrative expenses consist
primarily of personnel costs and related costs for general corporate functions,
including executive management and finance and fees for legal and other
professional services. General and administrative expenses increased to $1.1
million for the nine months ended September 30, 1999 from $35,000 for the nine
months ended September 30, 1998. The increase was primarily related to $710,000
in personnel-related costs and $415,000 in legal and accounting expenses
incurred to support the growth of our business. We expect general and
administrative expenses to increase in the future as we hire additional
personnel and incur additional costs related to the growth of our business and
operation as a public company. In addition, we expect to expand our facilities
and incur associated expenses to support our anticipated growth.

   Stock Compensation.  Options granted in the fourth quarter of 1998 and in
1999 have been considered to be compensatory as their deemed value for
accounting purposes was greater than the exercise prices as determined by the
board of directors on the dates of grant. For the nine months ended September
30, 1999, we recorded $9.9 million of deferred stock compensation. We amortized
$4.1 million in stock compensation in the nine months ended September 30, 1999.
Deferred stock compensation is being amortized over the respective vesting
periods of the outstanding options, generally four years.

 Years Ended December 31, 1998, 1997 and Period Ended December 31, 1996

   Revenues. Our total revenues were $15,000 in 1998. There were no revenues in
1997 and 1996. We first recognized advertising revenues in November 1998 as a
result of the launch of the HealthCentral.com website.

   Production, Content and Product Development. Production, content and product
development expenses were $137,000 in 1998. There were no production, content
and product development expenses in 1997 and 1996. Production, content and
product development expenses in 1998 were attributable to personnel costs
associated with the development of the HealthCentral.com website.

   Sales and Marketing. Sales and marketing expenses were $142,000 in 1998,
primarily due to $38,000 in sales and marketing personnel expenses and $103,000
in public relations expenses. We had $1,000 in sales and marketing expenses in
1997.

   General and Administrative. General and administrative expenses were $79,000
in 1998, primarily due to $67,000 in personnel expenses and $6,000 in
professional services fees. We had no general and administrative expenses in
1997.

                                       28
<PAGE>

   Stock Compensation. Through December 31, 1998, we had recorded a total of
$389,000 of deferred stock compensation. We recognized amortization of stock
compensation of $105,000 for the year ended December 31, 1998.

   Income Taxes. No provision for federal and state income taxes has been
recorded as we have incurred net operating losses through the year ended
December 31, 1998. As of December 31, 1998, we had approximately $239,000 of
federal and state net operating loss carryforwards available to offset future
taxable income. Due to the change in our ownership interests in connection with
this offering and prior sales of our equity securities, our use of these
federal and state net operating loss carryforwards will be subject to certain
annual limitations.

Liquidity and Capital Resources

   Since our inception, we have financed operations primarily through the sale
of our preferred stock and the issuance of notes payable. As of September 30,
1999, we had $16.2 million in cash and cash equivalents. Net cash provided by
financing activities was $1.9 million in 1998, which was the result of our
preferred stock financing in December 1998. Net cash provided by financing
activities was $1,000 in 1997, which was the result of the sale of common
stock. Net cash provided by financing activities was $8,000 in 1996, which was
the result of the sale of common stock. In August and September 1999, we sold
4,038,455 shares of Series B preferred stock resulting in net cash proceeds of
approximately $18.3 million. As of September 30, 1999 we had also issued notes
payable in the amount of $1.5 million, which were subsequently converted into
shares of Series B convertible preferred stock.

   Net cash used in operating activities was $2.9 million in the nine months
ended September 30, 1999 and $287,000 in 1998. Net cash used in operating
activities in 1999 was comprised primarily of a $9.1 million net operating loss
and a $1.0 million increase in prepaid expenses, partially reduced by $4.1
million in non-cash stock compensation expense, $553,000 in depreciation and
amortization of fixed and intangible assets, $1.1 million increase in accounts
payable, $635,000 in accrued expenses and $276,000 in amortization of a prepaid
license. Net cash used in operating activities was $1,000 in 1997 and $86 in
1996, both of which were the result of net operating losses.

   Net cash used in investing activities was $1.7 million for the nine months
ended September 30, 1999 and $564,000 in 1998. Cash used in investing
activities in the nine months ended September 30, 1999 was primarily due to
cash paid to the Windom Health shareholders in connection with that
acquisition. Cash used in 1998 was related to bridge loans made to Windom
Health. There were no changes in cash flows as a result of investing activities
in 1996.

   Although we have no material commitments for capital expenditures, we
anticipate substantial increases in our capital expenditures, minimum
advertising payments and lease commitments consistent with our anticipated
growth in operations, infrastructure and personnel.

   In September 1999, we entered into a three-year agreement with AltaVista to
develop a co-branded health channel. The agreement provides that, in exchange
for a minimum number of user impressions on the co-branded health channel, we
are obligated to pay AltaVista approximately $65.6 million in cash and stock
over the three-year term of the agreement; however, either AltaVista or we may
terminate the relationship after two years, in which case our aggregate payment
obligation over the first two years in cash and stock would be $34.5 million,
of which $1 million has been paid. In addition, in August 1999,
HealthCentralRx.com entered into a two-year agreement with America Online under
which HealthCentralRx.com appears as one of five anchor tenants on the America
Online HealthOnline Pharmacy Channel and receives a minimum number of
advertising impressions in exchange for payments of $12.3 million.

   Our capital requirements depend on numerous factors, including market
acceptance of our HealthCentral.com network, and the resources we allocate to
building our network, marketing and selling our

                                       29
<PAGE>

products and services, and promoting our brand. We have experienced substantial
increases in our expenditures since our inception, consistent with growth in
our operations and personnel, and we anticipate that our expenditures will
continue to increase for the foreseeable future. We currently expect to use the
net proceeds of this offering, along with our existing cash balances, primarily
to fund working capital and sales and marketing, to make cash payments of $31.5
million over the next two years to AltaVista, $12.3 million over the next two
years to America Online, $3 million in connection with our acquisition of
RxList.com and $1.25 million in connection with our acquisition of
HealthCentralRx.com, and to fund website and content development,
infrastructure improvements and operating losses. Additionally, we will
continue to evaluate possible acquisitions of or investments in complementary
businesses, technologies, services or products. We currently believe that our
available cash and cash equivalents at September 30, 1999, combined with the
net proceeds from this offering, will be sufficient to meet our anticipated
needs for working capital and capital expenditures for at least the next 12
months. We may need to raise additional capital, however, in order to fund more
rapid expansion, including significant increases in personnel and office
facilities; to develop new or enhance existing services or products; to respond
to competitive pressures; to enter into significant promotional partnerships;
or to acquire or invest in complementary businesses, technologies, services or
products. In addition, in order to meet our long term liquidity needs, we may
need to raise additional funds, establish a credit facility or seek other
financing arrangements. Additional funding may not be available on favorable
terms or at all.

Recent Accounting Pronouncements

   In June, 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard No. 133, "Accounting for Derivatives and Hedging
Activities." Statement No. 133 establishes accounting and reporting standards
for derivative instruments, including certain derivative instruments embedded
in other contracts, and for hedging activities. In July 1999, the Board issued
Statement No. 137, "Accounting for Derivative Instruments and Hedging
Activities--Deferral of the Effective Date of FASB Statement No. 133." This
Statement deferred the effective date of Statement No. 133 until fiscal years
beginning after June 15, 2000. We will adopt Statement No. 133 during the year
ending December 31, 2001. To date, we have not engaged in derivative or hedging
activities and we are unable to predict the impact of adopting Statement No.
133 if we were to engage in derivative and hedging activities in the future.

Disclosures About Market Risk

   Our exposure to market risk is limited to interest income sensitivity, which
is affected by changes in the general level of U.S. interest rates. Our cash
equivalents are invested with high quality issuers and limit the amount of
credit exposure to any one issuer. Due to the short-term nature of our cash
equivalents, we believe that we are not subject to any material market risk
exposure.

   We do not have any foreign currency hedging or other derivative financial
instruments as of September 30, 1999.

Year 2000 Compliance

   We may be exposed to a loss of revenues and our operating expenses could
increase if the systems on which we depend to conduct our operations are not
year 2000 compliant. Our potential areas of exposure include products purchased
from third parties, or embedded technology, information technology, or IT,
systems, including computers and software, and non-information technology,
including telephone systems and other equipment used internally. We have
completed our year 2000 testing of our internally developed IT systems, which
consist of internally developed software for the operation of our websites.
These software systems perform health risk assessments, process customer
interactions and transactions and provide distribution, monitoring and back-up
capabilities. Based on our assessment to date, we believe that our internally
developed IT systems are year 2000 compliant. In addition, the vendors of all
of our hardware systems have stated that their systems are year 2000 compliant.

                                       30
<PAGE>

   Our embedded technology consists of third party software, which is used in
our accounting, database and security systems, all of which has been purchased
in the last few years. We have contacted all of our third party software
vendors. We have either received assurances that their software is year 2000
compliant, or we have relied on statements on their websites to this effect.

   We do not currently expect that any major internal computers, applications
or equipment will have to be upgraded or modified to be year 2000 compliant. We
have not developed a contingency plan in the case of a material year 2000
problem, and do not plan to develop a contingency plan. We have not used any
independent verification processes to confirm the reliability of our estimates
of our year 2000 risks and costs.

   We are in the process of developing and integrating reporting, transaction
processing and fulfillment mechanisms with each of Bergen Brunswig and its
Medi-Mail subsidiary in order to operate our online drug store. If Bergen
Brunswig, Medi-Mail or our HealthCentralRx.com subsidiary experience year 2000
problems, our order processing, customer service, product delivery,
reimbursement mechanisms and other aspects of our online drug store business
could be seriously impaired. Bergen Brunswig and Medi-Mail have informed us
that they are year 2000 compliant. Bergen Brunswig has informed us that they
have not used independent verification and validation processes to confirm the
reliability of their assessment of their year 2000 risks. We use a java-based
Locomotive application server to facilitate the business logic for our e-
commerce business. Because this software is java-based, we do not anticipate a
year 2000 problem, but we have not received assurances from the vendor
regarding year 2000 compliance. If this server failed as a result of year 2000
problems, it could take a few weeks and up to $100,000 to replace, which could
impair our e-commerce business. We believe this scenario is our reasonably
likely worst case scenario for year 2000 issues.

   Our non-information, or non-IT, systems consist of telephone systems,
copiers and other equipment used internally. We have not performed a year 2000
assessment of our non-IT systems.

   We do not expect to spend more than $15,000 to assess and remediate the year
2000 problem based on the size of our operations, the percentage of our
software that is relatively new and conforms to industry-standards, and our
lack of older legacy software. No IT projects have been deferred due to our
year 2000 efforts.

   If our production and operational facilities that support our websites are
not year 2000 compliant, portions of our websites may become inaccessible. A
disruption in our operations could cause our users and customers to stop doing
business with us. If our webhosting facilities are not year 2000 compliant, our
websites would be unavailable and we would not be able to deliver services to
our users until we could relocate our servers to an unaffected facility. If our
present efforts to address the year 2000 compliance issues are not successful,
or if suppliers, telecommunications companies, financial institutions and other
third parties on whom we depend to conduct our business do not successfully
address such issues, our business could be significantly disrupted.

                                    BUSINESS

Company Overview

   We provide original, trustworthy, up-to-date and personalized online
healthcare information and sell health-related products to consumers through
our HealthCentral.com network. In addition, we enable healthcare institutions
to provide healthcare information to their patients and consumers through our
institutional Internet services business.

   Through our HealthCentral.com network, we derive revenue from advertisements
and the online sale of health-related products, or e-commerce. Through our
institutional Internet services business we derive revenue from annual license
fees for applications, content, hosting and maintenance services, as well as
from development fees for customization services.

   We believe we are strongly positioned to integrate a wide range of health-
related content with a complete healthcare e-commerce solution. Our goal is to
become the consumer's most trusted and complete online source of healthcare
information and products. We intend to accomplish this by:

  . providing credible, original, engaging and personalized content through
    our HealthCentral.com network;

  . offering a broad range of products through our online drug store,
    HealthCentralRx.com;

  . offering our content to our e-commerce customers to help them make
    better-informed purchases of health-related products;

  . maintaining the strict independence of our editorial content; and

  . utilizing a cross-media promotion strategy -- involving exposure in
    television, radio and print media -- which leverages our relationships
    with established medical media personalities from traditional media.

   Our HealthCentral.com network of interactive websites offers consumer-
oriented health content and health related e-commerce. Our flagship
HealthCentral.com website currently offers health-related content provided by
media personalities such as Dr. Dean Edell. Our HealthCentralRx.com online drug
store offers approximately 23,000 SKUs of prescription pharmaceutical products,
health and beauty aids, parenting and personal care products and nutritional
supplements. RxList.com is our online database of over 4,000 pharmaceuticals
and other medicines, with extensive information on 600 entries. We recently
entered into an agreement with AltaVista under which we will be the exclusive
healthcare content provider to its website, subject to conditions, and we
expect to launch our co-branded health channel in the first quarter of 2000. We
recently launched our PeoplesPharmacy.HealthCentral.com website, featuring Joe
and Teresa Graedon, and our Canadian co-branded health channel on MediaLinx.

   In addition, we act as an application service provider, which means that we
design, host and maintain websites for healthcare institutions. These websites
are private label websites, which means that they are branded under our
clients' own names and brands rather than ours. Some of our largest clients
include Brown and Toland, Scripps Clinic, Sutter Health and Catholic Healthcare
West.

Industry Background

 The Growth of the Internet and Electronic Commerce

   The Internet has revolutionized the way in which people obtain and exchange
information and transact business. International Data Corporation, or IDC,
estimates that the number of Internet users will increase from 142 million at
the end of 1998 to 500 million by the end of 2003. The Internet has unique and
powerful characteristics that differentiate it from traditional channels of
retail distribution, which are often narrow in selection, inconvenient, limited
in product information and lacking in privacy. IDC estimates that worldwide
business-to-consumer sales over the Internet will increase from approximately
$11 billion in 1998 to approximately $93 billion by 2002.

                                       32
<PAGE>

 The Growth of the Internet Healthcare Market

   The Internet has become an increasingly popular source for healthcare
information and products. Consumer research conducted by Cyber Dialogue in 1999
found that 24.8 million U.S. adults search for health information on the
Internet, with the number of people retrieving health-related information
projected to grow to 30 million in 2000. This growth in demand for online
health information has been driven by consumers seeking to make better personal
health care decisions. Consumers are also increasingly purchasing healthcare
products online. Forrester Research estimates that almost one third of a
surveyed group of Internet users shopped for health and personal care products
online during the previous six months. According to Jupiter Communications, the
total online and offline market for health goods, which includes over-the-
counter as well as prescription drugs, is expected to grow from $133.6 billion
in 1998 to $205.2 billion in 2003, while the amount of online consumer
purchases of healthcare goods is expected to grow from $2.4 million in 1998 to
$1.7 billion in 2003.

 Healthcare Industry Trends

   Consumers are taking it upon themselves to seek more information about their
healthcare needs for the following reasons:

  .  Patients' access to their physicians has become significantly reduced
     due to managed care.

  .  Employers are increasingly shifting healthcare costs and decisions to
     their employees.

  .  Insurance plans allow individuals greater choice in healthcare options,
     at increased personal costs.

  .  Advances in medicine have broadened treatment options for many medical
     conditions.

   The advent of the Internet has provided a medium for consumers to seek such
information. Moreover, the Internet allows consumers to seek information on
sensitive or embarrassing health issues while maintaining anonymity and
confidentiality.

   Payors and providers, who are faced with increasing economic pressures as an
outcome of managed care, are increasingly competing for consumers. Physician
groups compete to increase their patient bases to spread their administrative
costs and increase their negotiating leverage with payors. This competition in
the provider market is exacerbated by an oversupply of specialist physicians in
many markets and underutilization in many hospitals. Due to this increased
competition for members and patients, both payors and providers are looking for
ways to develop and maintain the loyalty of their existing members and patients
and attract new members and patients. Internet-based services enable health
plans and providers to differentiate their services, decrease their customer
support costs, and improve ties with their members or patients.

   The consumer has also become the marketing focus of commercial healthcare
enterprises, such as pharmaceutical and other healthcare products companies.
While pharmaceutical manufacturers have traditionally marketed their
prescription products to physicians, these companies have recognized that
consumers want to learn about and exercise greater control over their drug
therapies across an ever-widening list of conditions. Pharmaceutical companies
have thus begun advertising their products directly to consumers, most notably
through television advertising. This direct-to-consumer, or DTC, advertising is
increasing rapidly. Jupiter Communications projects that overall health-related
advertising spending in all forms of media will increase to $10.8 billion by
2003, while DTC advertising for pharmaceutical products will grow to almost
$3.8 billion. Advertisers are also increasingly turning to the Internet as a
medium to deliver their message. Jupiter Communications projects that overall
online health and medical advertising spending, including online DTC
advertising, will increase to $356 million by 2003, up from $12.3 million in
1998.

 Internet Healthcare Market Opportunities

   Although the Internet enables consumers to access healthcare information,
products and services, several Internet healthcare opportunities have yet to be
fully addressed. Despite approximately 15,000 healthcare

                                       33
<PAGE>

websites, online healthcare information is typically provided in a generic,
impersonal and sometimes misleading manner, with the line between editorial
content and advertising blurred. In addition, Internet services offered to
healthcare institutions typically offer no customization capabilities or
branding opportunity to these institutions.

   The interactive nature of the Internet enables a unique combination of
content provision with product offerings. However, the markets for health-
related content and e-commerce have not been well integrated to date. Online
merchants of health-related products are beginning to overcome the challenges
of inconvenience, narrow selection and lack of privacy that face traditional
store-based retailers. Yet, we believe these online merchants generally do not
offer content that is both wide-ranging and personalized in combination with
their product offerings.

HealthCentral.com Solution

   We provide original, trustworthy, up-to-date and personalized online
healthcare information and sell health-related products to consumers through
our HealthCentral.com network. In addition, we enable healthcare institutions
to provide healthcare information to their patients and consumers through our
institutional Internet services business.

 Our HealthCentral.com Network

   Our consumer-focused network of interactive websites currently consists of
our flagship HealthCentral.com website, our RxList.com pharmaceutical database
and our HealthCentralRx.com online drug store. We recently launched our
PeoplesPharmacy.HealthCentral.com website and our MediaLinx Canadian affiliate,
and we plan to launch our AltaVista co-branded health channel in the first
quarter of 2000. We also have important affiliations with other online
promotional and portal companies. Our HealthCentral.com network is a global
consumer health information source--from current fitness issues to complex
diseases--as well as an online drug store through which consumers can purchase
health-related products.

   Unique, Trustworthy and Engaging Health Information Content. Our
HealthCentral.com network is built on the provision of unique and engaging
information from medical professionals who have established a high degree of
trust with consumers through traditional media. Currently our original content
comes from established media sources such as Dr. Dean Edell, one of the leading
physician broadcasters in the United States over the past twenty years, and Joe
and Teresa Graedon, who host their own internationally syndicated radio show
and write The People's Pharmacy, a nationally syndicated newspaper column.

   Online Prescription Pharmaceuticals and Other Health-Related
Products. HealthCentralRx.com offers approximately 23,000 SKUs, of which
approximately 12,000 are prescription pharmaceuticals and approximately 11,000
are health and beauty aids and over-the-counter medications.
HealthCentralRx.com has fulfillment agreements with Bergen Brunswig, a major
drug distributor, for health and beauty aids, over-the-counter products and,
through Bergen Brunswig's Medi-Mail mail order pharmacy subsidiary,
prescription drug orders. Through this relationship with Bergen Brunswig and
Medi-Mail, HealthCentralRx.com also has access to the Good Neighbor Pharmacy
Network, a coalition of approximately 2,000 participating retail pharmacies
nationwide, and the PlusCare Provider Network of third-party pharmaceutical
benefit management companies, or PBMs. Collectively, these PBMs provide
prescription drug benefits for approximately 80 million covered lives.

   Personalized Level of Service. We personalize the level of service for our
visitors to enable them to make informed personal health decisions. Our
proprietary tools were designed and developed over a 15-year period by Windom
Health, whose efforts were in part funded through an advanced technology
program under a shared grant of $20 million from governmental and private
sources. By using our interactive features, visitors can receive a personal
health report outlining their greatest health risks, find information tailored
to their interests and build their online personal health record. This
personalized content includes action guides relating to visitors' particular
health concerns and free e-mail newsletters on specific healthcare topics, for
which we currently have approximately 450,000 subscriptions.

 Institutional Internet Services

   Primary Online Consumer Interface for Institutional Clients. We act as an
application service provider for healthcare institutions by designing, hosting
and maintaining their private label websites. Unlike many of our competitors,
we provide these services on a private label basis, which means that the
websites are branded under our clients' own names and brands rather than ours.
These private label websites enable our institutional clients to build needed
brand loyalty to retain and attract members and patients. We receive both
development fees for building customized websites and an annual license fee for
our content and interactive tools.

   Multiple Levels of Service to Institutional Clients. With our private label
websites, our institutional clients are able to improve their patient support
and marketing efforts, reduce their administrative costs of interacting with
their patients and provide relevant health information, control and choice to
the consumer. We offer three levels of application services:

  . QuickStart. Our entry-level service package, called QuickStart, can be
    implemented in as few as two days and provides basic tools.

  . A La Carte Application Licenses. Institutions may license any combination
    of our content and interactive software tools to incorporate into their
    own websites. We also offer administrative tools for both updating
    content and measuring site usage. License fees, which include fees for
    maintenance but not technical support, depend on the combination of tools
    and content licensed.

  . Comprehensive Website Development. Our premium service features
    comprehensive website development, in which we integrate the
    institutional customer's content and tools with our content and tools,
    then continually update our content and maintain the website. We receive
    both a fee, based on time and materials, for developing the website and
    an annual license fee, which includes four hours per month of maintenance
    and customer support. We also customize our tools to suit the specific
    institutional client's needs, which leads to the development of unique
    tools that can often be repurposed for use on our consumer network or on
    other institutional websites.

Our Strategy

   Our goal is to become the consumer's most trusted and complete online source
of healthcare information and products. We intend to accomplish this objective
by the following:

   Build Our Brands and Drive Network Traffic Through Our Cross-Media
Exposure. Our cross-media strategy entails increasing our exposure through the
promotional efforts of established medical professionals in traditional media
such as television, radio and newspaper, and through select Internet portal
relationships. We believe our cross-media strategy is a cost-effective means
for increasing and sustaining our network traffic. We intend to continue
building our cross-media exposure to build brand awareness and drive traffic to
HealthCentral.com and other websites on the HealthCentral.com network,
including RxList.com and HealthCentralRx.com.

  . Dr. Dean Edell. Dr. Dean Edell is the host of the Dr. Dean Edell Show, a
    daily one hour radio program on over 300 radio stations, including the 20
    largest radio markets in the United States. Dr. Edell typically refers
    listeners to our HealthCentral.com network several times on his daily
    one-hour syndicated radio program. He also has Medical Minutes radio

   are the authors of ten books, including The People's Pharmacy, a New York
   Times No. 1 best seller. We recently launched a co-branded website,
   PeoplesPharmacy.HealthCentral.com.

  . Portal Relationships with AltaVista, America Online and MediaLinx. In
    September 1999, we entered into an agreement with AltaVista under which
    we will be the exclusive healthcare content provider to its website,
    subject to conditions, and we expect to launch a co-branded health
    channel in the first quarter of 2000. HealthCentralRx.com has a two-year
    agreement with America Online, under which HealthCentralRx.com is one of
    the five health-related anchor tenants on the America Online HealthOnline
    Pharmacy Channel. We also recently launched our co-branded health website
    with MediaLinx, which manages the largest Internet service provider in
    Canada.

  . Other Internet Affiliations. We have agreements with portals and other
    websites, including AskJeeves.com, Broadcast.com, Looksmart, NetPulse,
    Snap.com and Yahoo!.

   Cultivate Multiple Revenue Streams. Our strategy is to develop our multiple
revenue streams to spread our business risk and leverage our intellectual
property:

  . Sponsorship and Advertising Fees. Companies can sponsor, through
    exclusive advertising, Health Topic Centers, which are pages devoted to
    specific health issues written and compiled by our editorial staff, or
    free e-mail newsletters requested by users on specific health topics. We
    currently have approximately 450,000 subscriptions to these newsletters.
    We generate advertising fees from placing ads, all of which are clearly
    delineated from our editorial content, on our websites. DoubleClick
    currently acts as our advertising sales agent for our HealthCentral.com
    website and, since January 1999, 100% of our available ad inventory has
    been sold. DoubleClick also acts as our advertising sales agent for our
    RxList.com website. We also intend to derive fees from developing bridge
    sites that allow users to access commercial information from various
    pharmaceutical and other healthcare companies.

  . e-commerce. HealthCentralRx.com, our online drug store, offers
    prescription pharmaceutical products, health and beauty aids, parenting
    and personal care products and nutritional supplements.
    HealthCentralRx.com currently delivers prescriptions, over-the-counter
    items, and health and beauty aids by mail order. In the first half of
    2000, we expect to make prescriptions available for pickup, and in some
    cases same-day delivery, from the approximately 2,000 local pharmacies in
    the Good Neighbor Pharmacy Network .

  .  Institutional Internet Services. Our institutional clients pay us fees
     for licensing our tools and content, as well as development fees for
     customized website development. We have developed a personal health
     record that enables our institutional clients to provide their members
     or patients with Internet access to personal health data. This service
     is currently in beta testing at Catholic Healthcare West.

   Deliver Compelling and Unique Content to Consumers. We intend to continually
add credible and compelling content and provide interactive and personalized
tools to retain visitors to our HealthCentral.com network. Our production and
editorial staff of 21 employees develops, screens, edits and compiles content
for our HealthCentral.com network, so that the healthcare information we
provide continues to be original, topical and engaging for our visitors.

   Attract a Growing Base of Customers to HealthCentralRx.com and Provide
Visitors with a Superior Shopping Experience. We intend to grow our online drug
store business by:

  .  offering consumers useful links to information related to products by
     integrating selected content and tools from HealthCentral.com,
     RxList.com and PeoplesPharmacy.HealthCentral.com;

  .  strengthening the HealthCentral.com brand through traditional and online
     advertising;

  .  expanding our broad range of consumer products and services;

  .  offering the consumer the choice of mail order delivery, in-store pickup
     or, in some cases, delivery from any of the approximately 2,000
     pharmacies in the Good Neighbor Pharmacy Network;

                                       36
<PAGE>

  .  encouraging repeat purchasing patterns by allowing customers to store
     frequently purchased items in their own personal shopping lists;

  .  continually improving the shopping experience by adding new features to
     the site; and

  .  maintaining a high level of customer service.

   Leverage Personalization Features. Our database of visitor information will
allow us to improve the user's return visits to our network by providing the
user with targeted content of particular interest. Each page of our content is
reviewed by our editorial staff and linked to specific health conditions or
interests. While protecting all confidential patient information, we can
provide advertisers and electronic merchants with direct links to highly
specialized target markets, enabling them to use DTC advertising more
efficiently.

   Maintain and Cultivate a Relationship of Trust with Consumers. Through our
affiliations with trusted media personalities such as Dr. Dean Edell and Teresa
and Joe Graedon of The People's Pharmacy, we enjoy a privileged and trusted
status with those consumers who seek our HealthCentral.com network based on
their experience with those personalities. We hold that level of trust in high
regard and seek to maintain it by providing consumers with reliable editorial-
reviewed content and by keeping individual consumer information confidential.
We strive to clearly delineate our editorial content from our advertising.

   Leverage Strategic Relationships. We have strategic relationships with
AltaVista, America Online, and Bergen Brunswig, which we plan to leverage into
increased traffic, branding and market power. We intend to pursue additional
complementary relationships that would provide us with a competitive advantage.

   HealthCentralRx.com

   HealthCentralRx.com, our online drug store, was founded in January 1999 and
in September 1999 launched its website. HealthCentralRx.com has fulfillment
agreements with Bergen Brunswig, a major drug distributor, for health and
beauty aids, over-the-counter products and, through Bergen Brunswig's Medi-Mail
mail order pharmacy subsidiary, prescription drug orders. HealthCentralRx.com
also has an agreement with Bergen Brunswig for access to the PlusCare Provider
Network of pharmacy benefit managers, which has approximately 80 million
covered lives. We expect that access to the PlusCare Provider Network will
enable many of our customers' prescription drug orders to be covered by their
pharmacy benefit managers.

   HealthCentralRx.com also has a two-year agreement with America Online under
which it is one of five health anchor tenants on the America Online
HealthOnline Pharmacy Channel, only three of which currently market
prescription pharmaceuticals on America Online.

 Products Available on Our HealthCentralRx.com Website

   We provide our customers with access to over 23,000 SKUs of prescription
pharmaceuticals, health and beauty aids and health-related over-the-counter
products through our relationship with Bergen Brunswig. Products are organized
on the HealthCentralRx.com website into the following categories:

  . Health. The health category includes over-the-counter remedies, such as
    cough, cold, allergy and pain relief medications, and products for eye
    and ear care, family planning, and home health. Representative brands
    carried in our health category include Bayer, Advil, Excedrin,
    Robitussin, Vicks and Alka-Seltzer.

  . Personal Care. The personal care market category includes products
    related to deodorants, foot care, men's care, oral hygiene, soaps and
    women's care. Representative brands carried in our personal care product
    category include Gillette, Revlon, Desenex, Rogaine, Crest, Ivory and
    Playtex.

  . Supplements. The supplements category includes adult nutritionals, diet,
    herbs, minerals, natural health, sports and fitness, and vitamins.
    Representative brands carried in our supplements category include Slim-
    Fast, Twin Labs, Weider, Centrum, Geritol and Power Bar.

  . Beauty. The beauty category includes cosmetics, fragrances, hair care,
    nail care, skin care and sun protection products. Representative brands
    carried in our beauty category include Cover Girl, L'Oreal, Christian
    Dior, Vidal Sassoon and Clairol.

  . Parenting. The parenting category includes baby care, child care and
    prenatal products. Representative brands carried in our parenting
    category include Tylenol Infant's, Advil, and Huggies.

  . Prescriptions. This category consists of prescription medication for
    chronic illnesses, such as high blood pressure, osteoporosis and
    depression, as well as for acute illnesses. These orders are currently
    delivered by mail, and we expect to make these medications available for
    pickup and, in some cases same-day delivery, from a local pharmacy in the
    Good Neighbor Pharmacy Network in the first half of 2000.

 Shopping @ HealthCentralRx.com

   Customers at HealthCentralRx.com can fill prescriptions and shop for brand
name health and beauty aids online from the privacy and convenience of their
homes. The HealthCentralRx.com site has a virtual shopping bag that keeps a
running tab of selected items and prices, allowing shoppers to quickly purchase
their needed healthcare products. The shopping bag remains to the right of
their screen while browsing so that consumers do not have to click to a
different page to select each product. To quickly find a particular item,
shoppers can use our search engine, browsing the entire inventory by key word,
such as the product name, brand name or description. By the first half of 2000,
we expect to offer ailment-related focus centers for customers interested in
finding and researching products by relevant health topic, such as allergies
and asthma, back and neck, dietary control, stress relief, fitness, women's
health and pain relief.

   To further enhance the shopping experience, we plan to supply the following
interactive tools and decision-support functionality:

  . My HealthCentralRx.com--personalization manager that creates custom
    shopping lists and page layouts according to set preferences and past
    behavior.

  . Rx Reminder--customizable shopping calendar for pre-order and re-
    order/refill.

  . Healthy Chat--chat rooms with virtual pointers to reference material,
    e.g., product description, health information.

   Currently, our customers can have their general questions about account
information, ordering products, and shipping status addressed by
HealthCentralRx.com customer care representatives. In addition, licensed
pharmacists at Medi-Mail are available to provide guidance, advice or
information about prescription medications concerning correct use and dosage,
generic alternatives, potential side effects and drug interactions.

 Prescription Pharmaceutical Orders

   Orders placed on our HealthCentralRx.com website for prescription
pharmaceuticals are processed, adjudicated and fulfilled under our agreement
with Medi-Mail, a mail order pharmacy, which is a wholly owned subsidiary of
Bergen Brunswig.

  .  Accepting Prescriptions. Our customers can initiate the prescription
     process by any one of the following methods: ordering online, directing
     their physician to call or fax the prescription to Medi-Mail or having
     Medi-Mail contact their physician directly to obtain prescription
     information. Medi-Mail is licensed to fill prescriptions in 48 of the 50
     states. Licenses to fill prescriptions are pending in Michigan and
     Tennessee.

  .  Verifying Prescriptions. Medi-Mail's licensed pharmacists are required
     to verify the validity and completeness of prescription drug orders.

  .  Verifying Prescription Drug Coverage. Medi-Mail determines the
     availability of prescription drug coverage and obtains all necessary
     approvals from healthcare providers within one business day of the
     placement of the order. If health insurance coverage is not available or
     denied for any reason, Medi-Mail will advise us so that we can arrange
     for payment in full by the consumer. Medi-Mail will not ship any order
     unless we have advised them that we have received payment in full from
     the consumer.

  .  Drug Utilization Review. In the future, we intend to build a database
     for each customer based upon his or her historical prescription usage at
     HealthCentralRx.com. We expect that the pharmacists at Medi-Mail will
     eventually be able to crosscheck each prescription received for
     allergies, therapeutic overlap, overuse/underuse and drug interactions
     with other drugs or foods.

  .  Delivery of Prescription Products. We offer our customers various
     shipping options, including next-day delivery service. By the first half
     of 2000, we expect to provide our customers with the ability to pick up
     and, in some cases receive same-day delivery of, their prescription
     drugs at any of the approximately 2,000 pharmacies in the Good Neighbor
     Pharmacy Network.

                                       41

 Distribution and Order Fulfillment for Non-Prescription Healthcare Products

   We outsource our distribution and order fulfillment operations for health
and beauty aids and over-the-counter product orders on an exclusive basis with
Bergen Brunswig. Our agreement with Bergen Brunswig for these services ends in
August 2004.

   Orders for health and beauty aids and over-the-counter products are placed
on our website and then forwarded to Bergen Brunswig by electronic data
interchange. Each order provides a description of the product, SKU
designations, quantities, method of payment, requested method of delivery and
the designated delivery location. We expect that Bergen Brunswig will maintain
sufficient inventory in an effort to facilitate the delivery of orders placed
on our sites. We currently offer approximately 11,000 SKUs of health and beauty
aids and over-the-counter products on our sites. We offer a variety of shipping
options, including UPS 3-5 day ground service, UPS 2nd day air and UPS Next Day
Air.

</TABLE>

Strategic Relationships

   We have the following strategic relationships:

   Dr. Dean Edell. In May 1999, we entered into a 15-year agreement with Dr.
Edell, in which he granted us the exclusive right to the use of his name in
connection with our business and exclusive commercialization

                                       42
<PAGE>

rights to his services over the Internet, except for the publication of radio
transcripts and Internet broadcasts of his radio program. Under this agreement,
we own all content that Dr. Edell creates for our HealthCentral.com network.

   America Online. In August 1999, HealthCentralRx.com entered into a two-year
agreement with America Online, under which HealthCentral.com will appear as one
of five health-related anchor tenants on the America Online HealthOnline
Pharmacy Channel. HealthCentralRx.com is required to pay approximately $14
million over the term of the agreement for a minimum number of advertising
impressions.

   AltaVista. In September 1999, we entered into a three year agreement with
AltaVista for the creation of a co-branded website on the AltaVista Health
Channel. We are the exclusive content provider on this co-branded site unless
we fail to provide desired content within a given period. Under the agreement,
AltaVista must deliver a minimum of advertising impressions and will receive
payments from us of up to $65.6 million in cash and stock issued at fair market
value over the three year term. In addition, we have agreed to issue AltaVista
warrants to purchase stock if they meet higher performance thresholds. If
AltaVista fails to deliver the minimum advertising impressions, we reduce our
payments to them. Either AltaVista or we may cancel the agreement after two
years.

   Bergen Brunswig. Bergen Brunswig is one of our stockholders and a strategic
partner. In July and September 1999, we entered into a series of agreements
whereby Bergen Brunswig will provide us with fulfillment services for health
and beauty aids, over-the-counter products and prescription drug orders. The
fulfillment agreement with Bergen Brunswig for health and beauty aids and over-
the-counter products is a five-year agreement and provides our customers with
access to over 11,000 SKUs. Our pharmacy services fulfillment agreement is with
Bergen Brunswig's mail order pharmacy, Medi-Mail, and has a term of five years
and provides our customers with access to over 12,000 prescription
pharmaceutical SKUs. Our relationship with Bergen Brunswig provides us access
to the Good Neighbor Pharmacy Network of approximately 2,000 independent
pharmacies and access to the PlusCare Provider Network of over 70 pharmacy
benefit managers covering approximately 80 million lives. Each of the PBMs has
entered into an agreement with Bergen Brunswig, pursuant to which it provides
pharmacy benefits for customers of approximately 4,000 individual pharmacies.
Medi-Mail is one of these pharmacies that has access to the benefits provided
by the PlusCare Provider Network.

   The People's Pharmacy. In September 1999, we entered into a four-year
agreement with Joe and Teresa Graedon to launch a co-branded website,
PeoplesPharmacy.HealthCentral.com, to provide users with exclusive Internet
access to pharmacy-related content produced by the Graedons in the form of
books, newspaper columns, and radio shows. The People's Pharmacy, a newspaper
column written by the Graedons and syndicated by King Features, is published in
over 150 newspapers, including in markets such as New York, Baltimore, Los
Angeles, Boston and Chicago. They also host a weekly radio show that is
broadcast on over 500 stations around the world. The Graedons have agreed to
participate in an interactive pharmacy chat room on the co-branded site. We
make annual payments to the Graedons and have issued them an option to purchase
up to a maximum of 250,000 shares of our common stock.

   MediaLinx. We recently launched our co-branded website with MediaLinx, an
Internet portal in Canada. MediaLinx manages Sympatico, the largest Internet
service provider in Canada. We expect that Canadian users accessing MediaLinx
will have access to our co-branded channel offering Canadian-specific health
content and editorials.

   We also have promotional, content distribution and portal relationships with
AskJeeves.com, Broadcast.com, Looksmart, NetPulse, Snap.com and Yahoo!.

Technology

   Our engineering mission is to provide a secure and confidential repository
for user information, provide high performance and high quality software and
application systems, and develop reusable components and

                                       43
<PAGE>

tools that integrate with evolving healthcare standards. Our HealthCentral.com
and HealthCentralRx.com websites employ similar three-tier software
architectures, and each is hosted on a different third-party web hosting
service. We plan to integrate the RxList.com and HealthCentralRx.com
applications, services and databases into the HealthCentral.com network
architecture.

   Physical Architecture. We employ a reliable and scalable server architecture
in a mixed LINUX, UNIX and Windows NT environment. Our HealthCentral.com
network, as well as our institutional clients' websites, are protected by an
industry standard firewall. All sensitive data is stored on a separate, private
network that is not directly accessible from the Internet. In addition, there
is a security system that includes video surveillance of all servers 24 hours a
day and a well-defined audit mechanism.

   Software Architecture. We employ a three-tier software architecture, which
allows customization, updating and repair of each layer without interfering
with the operation of the other layers. Our architecture consists of:

  . a user interface layer, which allows quick customization of applications
    and allows non-technical staff to maintain and improve the user interface
    and look and feel of both the HealthCentral.com network and our
    institutional clients' websites.

  . an engine layer, which implements the business logic for our
    applications. Our engine was developed over a 15-year period by Windom
    Health and enhanced by participation in an advanced technology program
    grant.

  . a database layer, which holds all content and data related to our website
    on a private network not directly connected to the Internet. An
    institutional client may choose to have its database reside with us or
    remain at the client's location. Our database servers are Oracle, Sybase
    on Sun Solaris for high end applications and MS SQL servers for low-end
    applications. We are in the process of improving the scalability of our
    database servers.

Sales and Marketing

 HealthCentral.com and RxList.com

   Our current sales and marketing strategy is to quickly build our revenues,
brand recognition and brand loyalty from sponsorships and advertising. Our
advertising campaigns target both online and traditional audiences and are
designed to promote an enhanced customer experience.

   Our online advertising efforts are focused on Internet portals and other
websites. We employ DoubleClick, the largest Internet advertising company, to
conduct advertising and sponsorship sales for our HealthCentral.com and
RxList.com websites. Our senior management participates with DoubleClick
representatives in important sales efforts. Under the terms of the agreement,
we cannot sell advertising, with some exceptions, for our HealthCentral.com
website through alternate avenues; however, the agreement is terminable by
either party on 90 days notice. 100% of our advertising inventory for the
HealthCentral.com website has been sold each month from January 1999 through
August 1999. We intend to continue to use the unique resources of the Internet
as a means of marketing in an effort to drive traffic and repeat purchases.

 HealthCentralRx.com

   Our current sales and marketing strategy is to establish brand awareness and
build brand loyalty of HealthCentralRx.com in order to drive sales of
prescription and non-prescription items. Our advertising and promotional
activities target both online and offline audiences and are initially designed
to attract first-time customers. To induce customer loyalty, we intend to
employ frequency reward programs based upon repeat purchases, where customers
will be able to accumulate points for every purchase and redeem them for prizes
and free products. In the first half of 2000, we plan to target people who
suffer from chronic conditions by offering disease-specific information and
building communities around common health concerns and prevention and health
management topics.

                                       44
<PAGE>

   Our online marketing efforts are focused on identifying and marketing to
early adopters of healthcare e-commerce, who we believe are typically women and
Internet users 45 years or older. We intend to reach these groups through co-
marketing initiatives with affiliate websites targeting female and mature
demographics, e.g, women's interests, parenting and family, investing, travel
planning, real estate, and senior-oriented sites. We intend to employ incentive
programs for affiliate sites to co-register users for our newsletter, as well
as reward affiliates for directing traffic to our site that results in
purchases. We also intend to acquire or rent opt-in e-mail lists to market
through e-mail based communications. We also plan to reinforce our online
marketing efforts through branded giveaway items in our product packaging,
e.g., HealthCentralRx.com-branded pill boxes, thermometer strips, pens, water
bottle straps, first-aid kits and band-aids.

   In addition to marketing through online channels, we intend to use
traditional marketing and promotional efforts, including print media campaigns,
TV, radio and billboards. We intend to increase our brand awareness through
associating with health and family-related events. In addition, we are in the
process of executing an extensive co-branding effort with the Good Neighbor
Pharmacy Network to extend our brand both online and offline and differentiate
our service through affiliation with trusted brick-and-mortar pharmacies.

 Institutional Internet Services

   Our current sales and marketing strategy is to quickly build our
institutional customer base, while deriving revenues from licensing and
development fees. We are in the process of building our direct sales teams for
our institutional Internet services.

Competition

   To be competitive, we must increase our site traffic and market share both
rapidly and significantly. Thus, we must attract and retain users to our
HealthCentral.com network by offering unique content and services, including
the ability to purchase health-related products, of particular interest to our
users.

 HealthCentral.com and RxList.com

   There are currently over 15,000 Internet websites that provide health-
related information. As a result, our industry is fragmented and competition is
extremely intense. Our HealthCentral.com and RxList.com consumer websites
compete directly for users, advertisers, e-commerce merchants and other
partners with numerous Internet and non-Internet businesses, including:

  .  health-related websites targeted at consumers, such as drkoop.com,
     AllHealth.com, DiscoveryHealth.com, InteliHealth, Medscape.com,
     OnHealth.com, Thrive.com and WebMD.com;

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

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

  .  consumer affinity groups, such as the American Association of Retired
     Persons and SeniorNet, which offer online healthcare-related content to
     special demographic groups.

 HeathCentralRx.com

   The online e-commerce markets in the health, beauty, wellness, personal care
and pharmacy categories are fragmented and intensely competitive. Our
competitors in these areas can be divided into several groups:

  .  chain drugstores, such as CVS, Eckerd and Walgreen's, and independent
     drug stores;

  .  mass market retailers, such as Kmart, Target and Wal-Mart;

                                       45
<PAGE>

  .  supermarkets and warehouse clubs;

  .  online retailers of health, beauty, personal care and/or pharmaceutical
     products, such as planetRx and drugstore.com;

  .  mail-order pharmacies and prescription benefits managers, such as
     Express Scripts and Merck-Medco;

  .  Internet-portals and online service providers that feature shopping
     services, such as America Online, Yahoo!, Excite and Lycos; and

  .  cosmetics departments at major department stores.

   Each of these competitors operate within one or more of the health, beauty,
wellness, personal care and pharmacy product categories. In addition, nearly
all of our competitors have, or have announced their intention to have, the
capability to accept orders for products online. In particular, Walgreen's,
CVS, Albertson's and Wal-Mart already are accepting prescription refill or
other orders on their websites.

   Many of these competitors have substantial competitive advantages over us,
such as:

  .  greater name recognition;

  .  larger user bases;

  .  greater financial, technical and other resources;

  .  the ability to offer a wider array of online products and services; and

  .  more diversified content offerings.

   We believe the main competitive factors in the health-related e-commerce
market are the availability of branded products, selection, convenience, price,
quality of search tools, and reliability and speed of fulfillment for products
ordered.

 Institutional Internet Services

   In the market for institutional Internet services, we compete mainly with
payors' and providers' internal systems development teams, with local web
development companies, with consumer-oriented websites that are selling
applications to institutions, such as drkoop.com, WebMD and BabyCenter's CHI
division. The main competitive factors in the institutional Internet services
market are depth of content, cost, development and maintenance ability and the
ability to allow the institutional client to promote its own brand.

Intellectual Property Rights

   Our intellectual property rights are important to our business. We rely on a
combination of copyright, trade secret, trademark and trade dress laws,
confidentiality procedures and contractual provisions to protect our
proprietary rights. We are in the process of filing for federal trademark
registrations for the trademarks "HealthCentral.com," "HealthCentralRx.com" and
"Windom Health." We have a 15-year agreement with Dr. Edell, in which he has
granted us the exclusive right to the use of his name in connection with our
business and exclusive commercialization rights to his services over the
Internet, except for the publication of radio transcripts and Internet
broadcasts of his radio program. Under this agreement, all content that Dr.
Edell creates for our HealthCentral.com network is owned by us. Windom Health
developed some elements of HealthView, the Personal Health Record and the
general architecture of the HealthCentral.com consumer website during its
participation in a project funded by a grant from the National Institute of
Standards and Technology. Under the terms of the grant, Windom Health owns the
intellectual property it developed for the project and granted a nonexclusive,
nontransferable license to the U.S. government of that intellectual property.
In addition, we have various other exclusive contractual rights. See "--
Strategic Relationships."

                                       46
<PAGE>

   Our policy is to enter into confidentiality and invention assignment
agreements with all employees and consultants, and nondisclosure agreements
with all potential business partners. These protections, however, may not be
adequate to protect our intellectual property rights. In addition, we may be
sued by third parties alleging, with or without merit, that we have violated
their intellectual property rights. See "Risk Factors--Any failure to protect
our intellectual property rights impair our ability to establish our brands"
and "--We may be sued by third parties for infringement of their proprietary
rights."

Government Healthcare Regulation

   General. Numerous state and federal laws regulate our health business, as
described below. Generally, the laws and regulations governing the healthcare
industry have not been tested in relation to e-commerce in healthcare products
and/or the provision of healthcare information on the Internet. The laws may be
interpreted in such a way that we may not be permitted to conduct our business
as described. The requirement that we comply with any new legislation or
regulations, or any unanticipated application or interpretation of existing
laws or regulations, may decrease the growth in the use of the Internet, which
could in turn decrease the demand for our products, services and information
offered through our HealthCentral.com network, increase our cost of doing
business or otherwise harm our business. See "Risk Factors--Extensive and
changing government regulation of the healthcare industries is expensive to
comply with and exposes us to the risk of substantial governmental penalties."

   Regulation of the Practice of Medicine. The practice of medicine is
generally defined by state law and varies from state to state. Often it is
defined as engaging in, with or without compensation, diagnosis or treatment of
a physical or mental condition. The practice of medicine requires a license
under state law and, depending on state law, practice of medicine without a
license can be a civil or criminal violation. We have endeavored to structure
our site and, in particular our health risk assessment tools and our
descriptions of various healthcare products, to avoid violation of state
licensing requirements. For example, we have included within our website
disclaimers and other notices that we have deemed appropriate to advise users
that the information provided is not intended to be a substitute for
consultation with a licensed physician. However, the application of this area
of the law to Internet services such as ours is novel and a key element of our
strategy is to encourage consumers to associate us with Dr. Dean Edell, a
licensed physician. Also, we have not conducted a state by state survey of
licensing requirements and policies. Accordingly, a state regulatory authority
and/or one or more licensed physicians or physician advocacy groups or
consumers may allege that one or more elements of our business requires a
license to practice medicine under existing or future laws or statutes and/or
that the disclaimer is ineffective as to particular consumers who claim to rely
upon advice or information provided by us. Any application of practice of
medicine regulations to our business could harm our business or require us to
change our business model. Further, liability based on a determination that we
engaged in the practice of medicine without a license may cause us to be
excluded from coverage under the terms of our current general liability
insurance policy and may also subject us to a higher standard of care than
would be applicable to activities that do not require a professional license.

   Regulation of Other Healthcare Professions. We provide information on
pharmacology, nutrition and mental health on our website, including
electronically accessible information regarding prescription drugs and answers
to frequently asked questions about prescription drugs. The practice of
pharmacology, nutrition, psychology and certain personal counseling is also
defined by and regulated by state law, which also varies from state to state.
While we have taken the same precautions to avoid the practice of other
healthcare professions as we have with the practice of medicine, a local
professional licensing board, local professionals, professional advocacy
groups, or consumers may seek to impose state law licensing requirements on
some aspects of our business. Any application of the regulation of the practice
of another healthcare profession to our business could harm our business or
require us to change our business model. Further, any liability based on a
determination that we engaged in the practice of a healthcare profession
without a license may cause us to be excluded from coverage under the terms of
our current general liability insurance policy and may also subject us to a
higher standard of care than would be applicable to activities which do not
require a professional license.

   Regulation of Pharmacy Prescription Drug Activities. Our business of
providing prescription drugs and other medical products is subject to federal,
state and local regulations, many of which are specific to pharmacies. For
example, pursuant to the Omnibus Budget Reconciliation Act of 1990 and related
state and local regulations, pharmacists are required to offer counseling,
without additional charge, to prescription drug customers about medication,
dosage, delivery systems, common side effects, adverse effects or interactions
and therapeutic contraindications, proper storage, prescription refill, and
other information deemed significant by the pharmacists. In addition, the FTC
and many state agencies regulate advertising and product performance claims for
prescription drugs. Pharmacy operations are subject to federal, state and local
licensing and registration regulations with respect to the Controlled
Substances Act and federal Drug Enforcement Agency regulations, as well as
related state and local laws and regulations, relating to pharmacy operations,
including registration, security, recordkeeping, and reporting requirements
related to the purchase, storage and dispensing of controlled substances and
prescription drugs, and certain over-the-counter drugs. We have attempted to
structure our agreement with Medi-Mail, for the fulfillment of prescription
orders, such that we do not have to qualify as a pharmacy under federal, state
and territorial laws and regulations. Medi-Mail is required to provide
pharmacist support to respond to consumer inquiries, and we are required to
provide consumer accessible electronic information including answers to
frequently asked questions about prescription drugs. Nevertheless, because we
are the interface with the consumer for the purchasing of prescription drugs,
we may be the subject of FDA, FTC, DEA and state agency enforcement actions and
could be liable to the consumer in the case of adulterated drugs, false or
misleading advertising or claims or problems with the transport and sale of
controlled substances. While we have rights against the drug manufacturer as to
adulteration issues and rights against Medi-Mail for problems relating to
compounding and dispensing drugs, we may have liability if the manufacturer
and/or Medi-Mail cannot or will not indemnify us in a specific situation.

   The U.S. House of Representatives Committee on Commerce and the General
Accounting Office are currently investigating online pharmacies and online
prescribing, especially focused on those who prescribe drugs online and on
pharmacies that fill invalid prescriptions, including those that are written
online. The committee requested that the General Accounting Office undertake a
formal review of a number of issues pertaining to online pharmacies, including
an assessment of mechanisms to ensure that online pharmacies are obeying the
various state and federal regulations for the industry. Any regulatory issues
or investigation of our fulfillment partners could involve us and could harm
our business, even if we had no direct liability.

   The National Association of Boards of Pharmacy, a coalition of state
pharmacy boards, has developed a program, the Verified Internet Pharmacy
Practice Sites, or VIPPS, as a model for self-regulation for online pharmacies.
As of September 15, 1999, the first VIPPS certifications were issued to
drugstore.com, Merck-Medco Rx Services and planetRx.com, which are now entitled
to display the VIPPS seal on their websites. To the extent that consumers rely
upon the VIPPS seal, it may be a competitive disadvantage if Medi-
Mail/HealthCentralRx.com does not obtain certification. In addition, various
state legislatures are considering new legislation related to the regulation of
nonresident pharmacies. The inclusion of prescription drugs as a Medicare
benefit has been the subject of numerous bills in the U.S. Congress. Should
legislation on prescription drug coverage for Medicare recipients be enacted
into law, compliance with any corresponding rules and regulations would be
required.

   Regulation of the Sale of OTC Drugs, Nutritional Supplements, Cosmetics and
Medical Devices. The FDA and FTC and similar state agencies regulate drug and
cosmetic advertising and promotion, including direct-to-consumer advertising,
done by or on behalf of drug and cosmetic manufacturers and marketers. In
addition, the FDA regulates product safety for nutritional supplements as well
as over-the-counter drugs, medical devices and prescription drugs. Many of our
products and services are subject to FDA and FTC regulation and enforcement for
false advertising and misleading advertising, including overstatements
regarding product performance, especially regarding nutritional supplements.
While we have rights against the manufacturer as to adulteration issues and
product claims (to the extent we have received the claims as a result of the
manufacturer), we may have liability if the manufacturer cannot or will not
indemnify us in a specific situation.

   Application of State and Foreign Laws. Although our business offices are
located in California, our website is available to users all over the United
States and the world. Therefore, the governments of other

                                       48
<PAGE>

states and foreign countries also regulate our activity and our transmissions
and may take action against us for violations of their laws. For example, many
states have enacted laws related to telemedicine, where physicians are
practicing medicine by various means of communication over state lines. The
states have varied tremendously in their approaches to this issue, including,
among others, requiring full licensing of the out of state practitioner or by
requiring the involvement of a state licensed practitioner. The states have
uniformly asserted their right to regulate telemedicine activity, based upon
the location of patients in their state, and we would expect the states to take
the same approach as to other electronic activities directed to consumers in
their states. In addition, our pharmacy business requires that our fulfillment
partner be registered as a pharmacy in any state where it delivers prescription
drugs. We have not undertaken a state by state or a country by country review
of the health-related laws that could apply to our business. Violations of
these laws may be alleged or charged by state or foreign governments or may be
modified, or new laws may be enacted, in the future. Any of the foregoing could
harm our business.

   Liability for Health Information and Health Products. Due to the nature of
our business, we may become involved in litigation regarding the information
transmitted from our site with the risk of adverse publicity, significant
defense costs and substantial damage awards. In addition, if we are deemed to
be engaged in the practice of medicine or another healthcare profession,
including pharmacy, we could be subject to claims and/or malpractice liability
exposure for which we may not be insured. We may also be liable for personal
and property damage from products provided by us, including from prescription
drugs. Finally, the FDA could look to us first in enforcing a product recall.
In recent years, participants in the healthcare industry have been subject to
an increasing number of lawsuits alleging malpractice, product liability and
related legal theories, many of which involve large claims and significant
defense costs. We have legal rights against the manufacturer and fulfillment
companies, with some limits, for their activities related to the products we
provide. To date, we have not been the subject of any claim involving the
operation of our site. However, claims may be brought against us. Even if these
claims ultimately prove to be without merit, defending against them can be
time-consuming and expensive, and any adverse publicity associated with these
claims could adversely affect our business. Our liability insurance does not
provide coverage for professional malpractice, so these claims would not come
within the scope of or be covered by our insurance. We may not be able to
maintain existing coverage or expand its scope to address evolving risks, or
obtain increased amounts of coverage on acceptable terms or at all.

   Medical Information and Data. There are changing federal and state laws
governing the storage, transmission and disclosure of medical information and
healthcare records. Our site does and will contain information submitted by
users, in response to questions on our personal health risk assessment and in
connection with prescription drug and other healthcare product orders. We
expect that our site will also contain information compiled by users for their
personal healthcare histories. While this information is not intended to
constitute or be treated as medical records, users or regulatory agencies may
seek to characterize this information as medical records and impose
requirements and/or sanctions upon us related to the maintenance and handling
of medical records. Maintaining this information could also expose us to claims
if unauthorized persons gain access to it notwithstanding our efforts to
maintain its security. On November 3, 1999, the Department of Health and Human
Services issued proposed regulations regarding standards to protect the privacy
of individually identifiable health information. We or third parties involved
in transmitting information to or through our site may have to comply with such
regulations in the future.

   Federal and State Anti-Kickback Laws. Provisions of the Social Security Act
known as the Federal Anti-Kickback Law prohibit knowingly or willfully,
directly or indirectly, paying or offering to pay, or soliciting or receiving,
any remuneration in exchange for the referral of patients to a person
participating in, or for the order, purchase or recommendation of items or
services that are subject to reimbursement by, Medicare, Medicaid and similar
other federal or state healthcare programs. Violations may result in civil and
criminal sanctions and penalties. Civil penalties include exclusion from
government health programs. Criminal sanctions include imprisonment for up to
five years and fines of up to $25,000 or both, for each violation. Recent
federal legislation expanded the sanctions to include civil monetary penalties
up to $50,000 for each prohibited act and up to three times the total amount of
remuneration offered, paid, solicited or received, even in circumstances

                                       49
<PAGE>

where a portion of such remuneration is offered, paid, solicited or received
for a lawful purpose. Certain courts reviewing the statute have taken a broad
view of the Federal Anti-Kickback Law and have ruled that it can be violated if
only one purpose of a payment arrangement is to induce referrals. Many states
also have enacted similar local anti-kickback laws.

   At present, neither Medicare nor Medicaid reimburses outpatient prescription
drugs, with the exception of a few items. While we believe that we have
structured our fee relationships with our pharmacy and health product
affiliates so that the Federal Anti-Kickback Law is not implicated for any
items or services covered by it, the agency may take a contrary position,
especially if Medicare and Medicaid benefits are expanded to cover prescription
drugs. If this were to happen, our prescription drug arrangement with our e-
commerce pharmaceutical and healthcare supply affiliates, as currently
structured, may not qualify as among the practices exempted from federal
prosecution or other enforcement under the Federal Anti-Kickback Law by the
regulatory safe harbors promulgated by the Department of Health and Human
Services. Failure to meet a safe harbor, however, does not mean that an
arrangement violates the statute. Many activities engaged in by healthcare
providers and related entities fall outside the safe harbors yet are not deemed
illegal. While we believe that our fee arrangements are not illegal as to
products and services reimbursable by Medicare or other federal programs
covered by the statute, given the breadth of the Federal Anti-Kickback Law, the
limited scope of the existing safe harbors and the desire of the agencies to
eliminate programs that create financial incentives to provide excessive care,
we may face adverse regulatory positions. The Office of Inspector General is
authorized to issue advisory opinions regarding the interpretation and
applicability of the Federal Anti-Kickback Law, including whether an activity
or proposed activity constitutes grounds for the imposition of civil or
criminal sanctions. We have not sought this kind of opinion and are aware of no
opinion that has been issued regarding website sponsorships or planned sales
activities.

   In addition, most states have enacted anti-kickback, or illegal
remuneration, laws that are similar to the Federal Anti-Kickback laws. Some of
these state laws are very closely patterned on the Federal Anti-Kickback Law;
others, however, are broader and reach reimbursement by private payors, and
still others are more narrow, applying, for example, only to kickbacks paid or
received by providers. We have not conducted a survey of these laws in all
fifty states and therefore, our arrangements with our e-commerce affiliates may
result in investigation or prosecution by state regulators or attorneys
general.

   If our activities were deemed to be inconsistent with the Federal Anti-
Kickback Law or with state anti-kickback or illegal remuneration laws, we could
face civil and criminal penalties or be barred from such activities, any of
which could harm our business. Further, we could be required to restructure our
existing or planned sponsorship compensation arrangements and e-commerce
activities in a manner that could harm our business.

   Federal and State Self-Referral Prohibitions. The federal physician self-
referral statute, often identified as the Stark Law, generally forbids payments
under Medicare or Medicaid based on a physician referral for "designated health
services" to any entity with which the physician or an immediate family member
has a financial relationship. The financial relationship can be direct or
indirect. The financial relationship can take the form of an ownership or
investment interest or a compensation relationship. A referral, under the Stark
Law, can include prescribing or requesting designated health services, and also
establishing a plan of care for the designated health services. The Stark Law
applies to clinical laboratory services and other designated health services,
including outpatient prescription drugs and durable medical equipment.
Penalties for violating the Stark Law include denial of payment from Medicare
and Medicaid programs for any services referred to an entity in violation of
the Stark Law, civil monetary penalties of up to $15,000 for each offense and
exclusions from the Medicare and Medicaid programs. Many states have adopted
similar self-referral laws, which may extend to governmental and third-party
payors. We have not conducted a survey of these laws in all fifty states.

   We have attempted to structure our physician relationships and our
information delivered to customers so that we are not viewed as practicing
medicine, either directly or as a vehicle for the practice of medicine by an
affiliated physician. However, if we were deemed to be a vehicle for a
physician referral for services or

                                       50
<PAGE>

equipment covered by federal or state self-referral laws, the manner in which
we are paid by the referral recipient could subject us to action under Stark or
state self-referral laws, which could harm our business and subject us to
sanctions under these laws.

   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.

Other Governmental Regulation

   General. There is an increasing number of laws and regulations pertaining to
the Internet. In addition, a number of legislative and regulatory proposals are
under consideration by federal, state, local and foreign governments and
agencies. Laws or regulations may be adopted with respect to the Internet
relating to liability for information retrieved from or transmitted over the
Internet, online content regulation, user privacy, taxation and quality of
products and services. Moreover, it may take years to determine whether and how
existing laws such as those governing issues such as intellectual property
ownership and infringement, privacy, libel, copyright, trade mark, trade
secret, obscenity, personal privacy, taxation, regulation of professional
services, regulation of medical devices and the regulation of the sale of other
specified goods and services apply to the Internet and Internet advertising.
The requirement that we comply with any new legislation or regulation, or any
unanticipated application or interpretation of existing laws, may decrease the
growth in the use of the Internet, which could in turn decrease the demand for
our service, increase our cost of doing business or otherwise harm our
business.

   Online Content Regulations. Several federal and state statutes prohibit the
transmission of indecent, obscene or offensive content over the Internet to
certain persons. In addition, pending legislation seeks to ban Internet
gambling and federal and state officials have taken action against businesses
that operate Internet gambling activities. The enforcement of these statutes
and initiatives, and any future enforcement activities, statutes and
initiatives, may result in limitations on the type of content and
advertisements available on HealthCentral.com. Legislation regulating online
content could slow the growth in use of the Internet generally and decrease the
acceptance of the Internet as an advertising and e-commerce medium, which could
impair our ability to generate revenues.

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

  . give adequate notice to consumers regarding information collection and
    disclosure practices;

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

  . provide consumers with access to their personal information and with the
    ability to rectify inaccurate information;

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

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

                                       51
<PAGE>

   Such regulation may also include enforcement and redress provisions. While
we have implemented programs designed to enhance the protection of the privacy
of our users, these programs may not conform with any regulations adopted by
the FTC. Moreover, even in the absence of such regulations, the FTC has begun
investigations into the privacy practices of companies that collect information
on the Internet. One such investigation has resulted in a consent decree
pursuant to which an Internet company agreed to establish programs to implement
the principles noted above. We may become subject to such an investigation, or
the FTC's regulatory and enforcement efforts may adversely affect the ability
to collect demographic and personal information from users, which could have an
adverse effect on the our ability to provide highly targeted opportunities for
advertisers and e-commerce marketers. Any of these developments could harm our
business.

   It is also possible that cookies may become subject to laws limiting or
prohibiting their use. The term cookies refers to information keyed to a
specific server, file pathway or directory location that is stored on a user's
hard drive, possibly without the user's knowledge and which is used to track
demographic information and to target advertising. Most currently available
Internet browsers allow users to modify their browser settings to remove
cookies at any time or prevent cookies from being stored on their hard drives.
In addition, a number of Internet commentators, advocates and governmental
bodies in the United States and other countries have urged the passage of laws
limiting or abolishing the use of cookies. Limitations on or elimination of the
use of cookies could limit the effectiveness of the targeting of
advertisements, which could impair our ability to generate advertising revenue.

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

   Planned features of our website include the retention of personal
information about our users which we obtain with their consent. We have a
stringent privacy policy covering this information. However, if third persons
were able to penetrate our network security and gain access to, or otherwise
misappropriate, our users' personal information, we could be subject to
liability. This liability could include claims for misuses of personal
information, such as for unauthorized marketing purposes or unauthorized use of
credit cards. These claims could result in litigation, our involvement in
which, regardless of the outcome, could require us to expend significant
financial resources. Moreover, to the extent any of the data constitutes or is
deemed to constitute patient health records, a breach of privacy could violate
federal law.

   Data Protection. Legislative proposals have been made by the federal
government that would afford broader protection to owners of databases of
information, such as stock quotes and sports scores. This kind of protection
already exists in the EU. If enacted, this legislation could result in an
increase in the price of services that provide data to websites. In addition,
this legislation could create potential liability for unauthorized use of this
data.

   Internet Taxation. A number of legislative proposals have been made at the
federal, state and local level, and by foreign governments, that would impose
additional taxes on the sale of goods and services over the Internet, and some
states have taken measures to tax Internet-related activities. Although
Congress recently placed a three-year moratorium on state and local taxes on
Internet access or on discriminatory taxes on electronic commerce, existing
state or local laws were expressly excepted from this moratorium. Further, once
this moratorium is lifted, some type of federal and/or state taxes may be
imposed upon Internet commerce. This

                                       52
<PAGE>

legislation or other attempts at regulating commerce over the Internet may
substantially impair the growth of commerce on the Internet and, as a result,
adversely affect our opportunity to derive financial benefit from these
activities.

   Domain Names. Domain names are the user's Internet address. Domain names
have been the subject of significant trademark litigation in the United
States. Third parties may bring claims for infringement against us for the use
of the HealthCentral.com or the HealthCentralRx.com trademarks. Moreover,
because domain names derive value from the individual's ability to remember
these names, our domain names may lose their value if, for example, users
begin to rely on mechanisms other than domain names to access online
resources.

   The current system for registering, allocating and managing domain names
has been the subject of litigation and of proposed regulatory reform. Our
domain names may lose their value, or we may have to obtain entirely new
domain names in addition to or in lieu of our current domain names if
litigation or reform efforts result in a restructuring in the current system.

   State Insurance Regulation. In the future we may market insurance online.
The use of the Internet in the marketing of insurance products is a relatively
new practice. It is not clear whether or to what extent state insurance
licensing laws apply to these activities. If we were required to comply with
such licensing laws, compliance could be costly or impossible, which could
harm our business or require us to change our business plans.

   Jurisdiction. Due to the global reach of the Internet, it is possible that,
although our transmissions over the Internet originate primarily in the State
of California, the governments of other states and foreign countries might
attempt to regulate Internet activity and our transmissions or take action
against us for violations of their laws. Violations of these laws may be
alleged or charged by state or foreign governments, or these laws may be
modified, or new laws enacted, in the future. Any of the foregoing could harm
our business.

Employees

   As of October 15, 1999, we had 73 employees, of which 14 were employed in
sales and marketing, 25 were employed in engineering, 21 were employed in
production, and 13 were employed in general management and administration. We
believe that our relations with our employees is good.

Facilities

   We lease a total of approximately 22,600 square feet at our three
facilities in Emeryville, California. The lease for approximately 7,300 square
feet expires in March 2004, the lease for approximately 8,800 feet expires in
December 2003 and the lease for approximately 6,500 square feet expires in
June 2002. We have also entered into a license agreement to use facilities in
Stamford, Connecticut. This agreement renews every three months and the
current agreement will expire in November 1999.

Legal Proceedings

   We have no pending legal proceedings, however we may become subject to
lawsuits from time to time.

Board Composition

   Our bylaws currently provide for a board of directors consisting of nine
members. All directors hold office until the next annual meeting of our
stockholders and until their successors have been elected and qualified.
Although our principal stockholders have agreed to be bound by a voting
agreement providing for the election of all of our directors, this voting
agreement will terminate upon completion of this offering.

   In accordance with the terms of our amended and restated certificate of
incorporation to be effective upon completion of this offering, the board of
directors will be divided after the completion of this offering into the
following three classes, each serving staggered three-year terms: Class I,
whose initial term will expire at the annual meeting (or special meeting held
in lieu of the annual meeting) of stockholders in 2000; Class II, whose initial
term will expire at the annual meeting (or special meeting held in lieu of the
annual meeting) of stockholders in 2001; and Class III, whose initial term will
expire at the annual meeting (or special meeting held in lieu of the annual
meeting) of stockholders in 2002. As a result, only one class of directors will
be elected at each annual meeting of stockholders of HealthCentral.com, with
the other classes continuing for the remainder of their respective terms. These
provisions in our amended and restated certificate of incorporation may have
the effect of delaying or preventing changes in the control or management of
HealthCentral.com.

   Except for reimbursement for reasonable travel expenses relating to
attendance at board meetings and the grant of stock options, our directors do

   In addition, Mr. Greene was granted the following restricted stock awards
during 1998, each with a purchase price equal to the fair market value of our
common stock, as determined by our board of directors at the time granted:

  . In February 1998, Mr. Greene was issued 55,991 shares of common stock at
    a purchase price of $0.04 per share for a total purchase price of $2,429,
    which amount was paid through the cancellation of indebtedness owing for
    the performance of services previously rendered by Mr. Greene. At the end
    of the fiscal year ended December 31, 1998, this common stock was valued
    at $559,910, assuming that the fair market value as of that date was
    equal to the assumed offering price of $10.00 per share.

  . In September 1998, Mr. Greene was issued 23,916 shares of common stock at
    a purchase price of $0.25 per share, for a total purchase price of
    $5,931, in exchange for Mr. Greene's issuance to us of a promissory note.
    At the end of the fiscal year ended December 31, 1998, this common stock
    was valued at $239,160, assuming that the fair market value as of that
    date was equal to the assumed offering price of $10.00 per share.

Option Grants

   The following table shows information regarding a stock option granted to
Mr. Greene, our Chief Executive Officer and President. Mr. Greene was a
consultant during 1998, and, at December 31, 1998, he was our only executive
officer. No stock appreciation rights were granted to Mr. Greene during that
year.

   The stock option listed in the following tables was granted under the 1998
stock plan and has fully vested. The percentage below is based on a total of
149,718 shares subject to options granted by us during the year ended December
31, 1998 to all of our employees and consultants. The exercise price per share
of the option was equal to the fair market value of the common stock on the
date of grant as determined by the board of directors. Potential realizable
values assume that the assumed offering price of $10.00 per share was the fair
market value of the common stock on the date of grant and that the price of the
applicable stock increases from the date of grant until the end of the ten-year
option term at the annual rates specified. There is no assurance provided to
any executive officer or any other holder of our securities that the actual
stock price appreciation over the 10-year option term will be at the assumed 5%
and 10% levels or at any other defined level.

Employment and Consulting Agreements

   In August 1999, we entered into an employment agreement with Mr. Greene, our
Chief Executive Officer and President, which provides that Mr. Greene receives
an initial base salary of $235,000 and is eligible to receive a bonus of from
30% to 60% of his base salary depending on his achievement of performance
milestones. If Mr. Greene is terminated without cause before August 11, 2000,
he will receive monthly severance payments equal to his monthly base salary
until that date.

   A June 1999 offer letter to Mr. Toney, our Chief Financial Officer and
Senior Vice President, provides that Mr. Toney receives an initial base salary
of $200,000, with an incentive bonus of up to 30% of his base salary depending
on his achievement of performance milestones. In the first year of his
employment, Mr. Toney is guaranteed a bonus of at least 15% of his base salary.
If Mr. Toney is terminated without cause during the first year of his
employment, he will receive monthly severance payments equal to his monthly
base salary until the later of the one year anniversary of his employment start
date or six months after his termination date.

                                       58
<PAGE>

   Messrs. Greene and Toney also have change of control provisions, which
provide that fifty percent of their unvested shares and options vest on an
acquisition of our company, and that if they are terminated without cause
within 12 months after an acquisition of our company, the remaining unvested
shares vest automatically at that time.

   A March 1999 offer letter to Ms. Buddrus, our Vice President of Production,
provides that Ms. Buddrus receives a base salary of $110,000, with an incentive
bonus up to $40,000 depending on her achievement of performance milestones. An
August 1999 letter provides that if Ms. Buddrus is terminated without cause
during the first year of her employment, she will receive monthly severance
payments equal to her monthly salary until the later of the one year
anniversary of her employment start date or six months after her termination
date.

   In August 1999, we entered into employment agreements with Dr. Van Brunt,
our Senior Vice President of Operations, and Mr. Athanasoulis, our Vice
President of Engineering, in connection with our acquisition of Windom Health.
These employment agreements each provide that if the officer is terminated
without cause before August 11, 2000, he will receive monthly severance
payments equal to his monthly base salary until that date.

   In September 1999, the board of directors amended option agreements held by
our officers to provide that fifty percent of any unvested options vest on our
acquisition by another company and the remaining fifty percent vest monthly
over 12 months.

Stock Plans

   1999 Stock Plan. Our 1999 stock plan provides for the grant of incentive
stock options to employees, including employee directors, and the grant of
nonstatutory stock options and stock purchase rights to employees, directors
and consultants. The purposes of the 1999 plan are to attract and retain the
best available personnel, to provide additional incentives to our employees and
consultants and to promote the success of our business. The 1999 plan was
originally adopted by our board of directors in August 1999. At the time of
adoption, 250,000 shares of common stock were reserved for issuance under the
1999 plan. The 1999 plan was amended by our board of directors in September
1999 to increase the total number of shares reserved for issuance by 4,375,000
shares, and to incorporate certain other changes, after which amendment a total
of 4,625,000 shares of common stock has been reserved for issuance under the
plan. In addition, the 1999 plan was amended to provide for an automatic annual
increase on the first day of each of our fiscal years beginning in 2001, 2002,
2003, 2004 and 2005 equal to the lesser of 787,500 shares, 3.5% of our
outstanding common stock on the last day of the immediately preceding fiscal
year, or a lesser number of shares as the board of directors determines. These
amendments to the 1999 plan were approved by our stockholders in November 1999.
Unless terminated earlier by the board of directors, the 1999 plan will
terminate in August 2009.

   As of September 30, 1999, options to purchase 250,000 shares of common stock
were outstanding under the 1999 plan at a weighted average exercise price of
$1.28 per share, and no shares had been issued upon exercise of outstanding
options or pursuant to restricted stock purchase agreements.

   The 1999 plan may be administered by the board of directors or a committee
of the board, each known as the administrator. The administrator determines the
terms of options and stock purchase rights granted under the 1999 plan,
including the number of shares subject to the award, the exercise or purchase
price, and the vesting and/or exercisability of the award and any other
conditions to which the award is subject. In no event, however, may an employee
receive awards for more than 2,000,000 shares under the 1999 plan in any fiscal
year. Incentive stock options granted under the 1999 plan must have an exercise
price of at least 100% of the fair market value of the common stock on the date
of grant. The exercise price of nonstatutory stock options and the purchase
price of stock purchase rights is determined by the administrator, although we
expect that nonstatutory stock options and stock purchase rights granted to our
Chief Executive Officer and our four

                                       59
<PAGE>

other most highly compensated officers will generally equal at least 100% of
the grant date fair market value. Payment of the exercise or purchase price may
be made in cash or such other consideration as determined by the administrator.

   With respect to options granted under the 1999 plan, the administrator
determines the term of options, which may not exceed 10 years (or 5 years in
the case of an incentive stock option granted to a holder of more than 10% of
the total voting power of all classes of our stock). Generally, an option
granted under the 1999 plan is nontransferable other than by will or the laws
of descent and distribution, and may be exercised during the lifetime of the
optionee only by the optionee. However, the administrator may in its discretion
provide for the limited transferability of nonstatutory stock options granted
under the 1999 plan under certain circumstances. Stock issued pursuant to stock
purchase rights granted under the 1999 plan is generally subject to a
repurchase right exercisable by us upon the termination of the holder's
employment or consulting relationship with us for any reason (including death
or disability). This repurchase right will lapse in accordance with the terms
of the stock purchase right determined by the administrator at the time of
grant.

   If we are acquired by another corporation, the vesting and exercisability
applicable to outstanding options and stock purchase rights and to shares
outstanding under the 1999 plan will accelerate as to 50% of the award that is
unvested at the time of the transaction. In addition, outstanding options and
stock purchase rights may be assumed or an equivalent award substituted by our
acquiror. However, if the acquiror does not agree to such assumption or
substitution, outstanding awards will become fully vested and exercisable
immediately prior to consummation of the transaction and then terminate upon
such consummation. Outstanding awards will adjust in the event of a stock
split, stock dividend or other similar change in our capital. The administrator
has the authority to amend or terminate the 1999 plan, but no action may be
taken that impairs the rights of any holder of an outstanding option or stock
purchase right without the holder's consent. In addition, we must obtain
stockholder approval of amendments to the plan as required by applicable law.

   1998 Stock Plan. Our 1998 stock plan was adopted by our board of directors
and approved by our stockholders in August 1998. The 1998 plan provides for the
grant to employees, including employee directors, of incentive stock options
and the grant of nonstatutory stock options and stock purchase rights to
employees, consultants and directors. An aggregate of 3,000,000 shares of
common stock have been reserved for issuance under the 1998 plan. As of
September 30, 1999, options to purchase 1,756,157 shares of common stock at a
weighted average exercise price of $1.29 were outstanding, 398,916 shares with
a weighted average purchase price of $1.06 have been issued upon exercise of
options or stock purchase rights and 844,927 shares remain available for future
grant. Unless terminated earlier, the 1998 plan will terminate in August 2008.

   The terms of options and stock purchase rights issued under our 1998 plan
are generally the same as those that may be issued under our 1999 plan, except
that the 1998 plan imposes a limitation of 1,250,000 on the number of shares of
stock subject to options and stock purchase rights that may be granted to any
individual employee during a fiscal year.

   1999 Employee Stock Purchase Plan. Our 1999 employee stock purchase plan was
adopted by our board of directors in September 1999 and approved by our
stockholders in November 1999. A total of 1,250,000 shares of common stock has
been reserved for issuance under the 1999 purchase plan, none of which have
been issued as of the date of this offering. The number of shares reserved for
issuance under the 1999 purchase plan will be subject to an automatic annual
increase on the first day of each of our fiscal years beginning in 2001, 2002,
2003, 2004 and 2005 equal to the lesser of 437,500 shares, 2% of our
outstanding common stock on the last day of the immediately preceding fiscal
year, or a lesser number of shares as the board of directors determines. The
1999 purchase plan becomes effective upon the date of this offering. Unless
terminated earlier by the board of directors, the 1999 purchase plan shall
terminate in September 2019.

   The 1999 purchase plan, which is intended to qualify under Section 423 of
the Internal Revenue Code, will be implemented by a series of overlapping
offering periods of approximately 24 months' duration, with new offering
periods (other than the first offering period) commencing on February 1 and
August 1 of each

                                       60
<PAGE>

year. Each offering period will generally consist of four consecutive purchase
periods of six months' duration, at the end of which an automatic purchase will
be made for participants. The initial offering period is expected to commence
on the date of this offering and end on January 31, 2002; the initial purchase
period is expected to begin on the date of this offering and end on July 31,
2000, with subsequent purchase periods ending on January 31, 2001, July 31,
2001 and January 31, 2002. The 1999 purchase plan will be administered by the
board of directors or by a committee appointed by the board. Our employees
(including officers and employee directors), or of any majority-owned
subsidiary designated by the board, are eligible to participate in the 1999
purchase plan if they are employed by us or the subsidiary for at least 20
hours per week and more than five months per year. The 1999 purchase plan
permits eligible employees to purchase common stock through payroll deductions,
with the maximum payroll deduction rate capped at 20% of a participant's
compensation. The purchase price is equal to the lower of 85% of the fair
market value of the common stock at the beginning of each offering period or at
the end of each purchase period, subject to certain adjustments as provided in
the plan. Employees may end their participation in the 1999 purchase plan at
any time during an offering period, and participation ends automatically on
termination of employment.

   An employee is not eligible to participate in the 1999 purchase plan if
immediately after the grant of an option to purchase stock under the plan he or
she would own stock and/or hold outstanding options to purchase stock equaling
5% or more of the total voting power or value of all classes of our stock or
stock of our subsidiaries, or if such option would permit an employee's rights
to purchase stock under the 1999 purchase plan to accrue at a rate that exceeds
$25,000 of fair market value of such stock for each calendar year in which the
option is outstanding. In addition, no employee may purchase more than 2,500
shares of common stock under the 1999 purchase plan in any one purchase period.
If the fair market value of the common stock on a purchase date is less than
the fair market value at the beginning of the offering period, each participant
in that offering period will automatically be withdrawn from the offering
period as of the end of the purchase date and re-enrolled in the new twenty-
four month offering period beginning on the first business day following the
purchase date.

   If we merge or consolidate with or into another corporation or sell all or
substantially all of our assets, each right to purchase stock under the 1999
purchase plan will be assumed or an equivalent right substituted by our
acquiror. If our acquiror did not agree to assume or substitute stock purchase
rights, any offering period and purchase period then in progress would be
shortened and a new purchase date occurring prior to the closing of the
transaction would be set. Our board of directors has the power to amend or
terminate the 1999 purchase plan and to change or terminate offering periods as
long as such action does not adversely affect any outstanding rights to
purchase stock thereunder. However, the board of directors may amend or
terminate the 1999 purchase plan or an offering period even if it would
adversely affect outstanding options in order to avoid our incurring adverse
accounting charges.

   Assumed HealthCentralRx.com 1999 Stock Option Plan. We assumed the
HealthCentralRx.com 1999 Stock Option Plan in connection with our acquisition
of HealthCentralRx.com in October 1999. The HealthCentralRx.com 1999 option
plan provides for the grant to employees of incentive stock options and the
grant of nonstatutory stock options to employees, consultants and directors. As
of October 31, 1999, options to purchase 86,968 shares of common stock at a
weighted average exercise price of $2.38 were outstanding under this plan. We
do not currently anticipate granting any other options under this plan. Unless
terminated earlier, the HealthCentralRx.com 1999 option plan will terminate in
February 2009.

   The terms of options issued under our HealthCentralRx.com 1999 option plan
are generally the same as those that may be issued under our other 1999 plan,
except with respect to the following features. The HealthCentralRx.com 1999
option plan does not impose a limit on the number of shares of stock subject to
options that may be granted to any individual employee during a fiscal year,
and it does not allow for the granting of stock options with any
transferability rights.

   1999 Directors' Stock Option Plan. The 1999 directors' stock option plan was
adopted by the board of directors in September 1999 and approved by our
stockholders in November 1999. It will become effective upon the date of this
offering. A total of 312,500 shares of common stock has been reserved for
issuance under

                                       61
<PAGE>

the directors' plan, all of which remain available for future grants. The
directors' plan provides for the grant of nonstatutory stock options to our
nonemployee directors. The directors' plan is designed to work automatically
without administration; however, to the extent administration is necessary, it
will be performed by the board of directors. To the extent they arise, it is
expected that conflicts of interest will be addressed by abstention of any
interested director from both deliberations and voting regarding matters in
which the director has a personal interest. Unless terminated earlier, the
directors' plan will terminate in September 2009.

   The directors' plan provides that each person who becomes a nonemployee
director after the completion of this offering will be granted a nonstatutory
stock option to purchase 12,500 shares of common stock on the date on which he
or she first becomes a member of our board of directors. In addition, on the
date of each annual stockholders meeting, each nonemployee director who will
continue serving on the board following the meeting and who has been a director
of HealthCentral.com for at least six months prior to the meeting date will be
granted an option to purchase 6,250 shares of common stock.

   All options granted under the directors' plan will have a term of ten years
and an exercise price equal to the fair market value of the common stock on the
date of grant and will be nontransferable. All options granted under the
directors' plan to new directors shall vest monthly over four years from the
date of a grant and all options granted at the time of our annual stockholders
meeting will vest monthly over 12 months. If a nonemployee director ceases to
serve as a director for any reason other than death or disability, he or she
may, but only within 90 days after the date he or she ceases to be a director,
exercise options granted under the directors' plan. If he or she does not
exercise the option within this 90-day period, the option will terminate. If a
director's service terminates as a result of his or her disability or death, or
if a director dies within three months following termination for any reason,
the director or his or her estate will have 12 months after the date of
termination or death, as applicable, to exercise options that were vested as of
the date of termination.

   If we are acquired by another corporation, each option outstanding under the
directors' plan will be assumed or equivalent options substituted by our
acquirer, unless our acquirer does not agree to such assumption or
substitution, in which case the options will terminate upon consummation of the
transaction to the extent not previously exercised. In connection with any
acquisition, each director holding options under the directors' plan will have
the right to exercise his or her options immediately before the consummation of
the merger as to all shares underlying the options, including shares which
would not have been vested and exercisable but for the acquisition. Our board
of directors may amend or terminate the directors' plan as long as the action
does not adversely affect any outstanding option. We will obtain stockholder
approval for any amendment to the extent required by applicable law.

Limitation of Liability and Indemnification Matters

   Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except liability for:

  . any breach of their duty of loyalty to the corporation or its
    stockholders;

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

  . unlawful payments of dividends or unlawful stock repurchases or
    redemptions; or

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

   Such limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission. Our certificate of

                                       62
<PAGE>

incorporation and bylaws provide that we shall indemnify our directors and
executive officers and may indemnify our other officers and employees and other
agents to the fullest extent permitted by law. We believe that indemnification
under our bylaws covers at least negligence and gross negligence on the part of
the indemnified parties. Our bylaws also permit us to secure insurance on
behalf of any officer, director, employee or other agent for any liability
arising out of his or her actions in such capacity, regardless of whether the
bylaws would permit indemnification.

   We have entered into agreements to indemnify our directors and executive
officers in addition to indemnification provided for in our bylaws. These
agreements, among other things, provide for indemnification of our directors
and executive officers for expenses specified in the agreements, including
attorneys' fees, judgments, fines and settlement amounts incurred by any such
person in any action or proceeding arising out of such person's services as a
director or executive officer of HealthCentral.com, any subsidiary of
HealthCentral.com or any other entity to which the person provides services at
our request. In addition, we maintain directors' and officers' insurance. We
believe that these provisions and agreements are necessary to attract and
retain qualified persons as directors and executive officers.

   At present, we are not aware of any pending or threatened litigation or
proceeding involving a director, officer, employee or agent in which
indemnification would be required or permitted. We are not aware of any
threatened litigation or proceeding that might result in a claim for such
indemnification.

                          TRANSACTIONS WITH AFFILIATES

   Since January 1, 1996, we have issued shares of our convertible preferred
stock and warrants to purchase our common stock and preferred stock to
investors in private placement transactions as follows: a total of 1,012,500
shares of Series A preferred stock at a price of $2.00 per share and warrants
to purchase 486,000 shares of Series A preferred stock at a price of $2.00 per
share in December 1998, and a total of 4,038,455 shares of Series B preferred
stock at a price of $5.20 per share in August and September 1999. The following
table summarizes the shares of preferred stock purchased by, and warrants to
purchase shares of Series A preferred stock issued to, our executive officers,
directors, including Jeff Edwards, who resigned as a director in August 1999,
and 5% stockholders and persons and entities associated with them in these
private placement transactions. Current fair market values listed in the table
are based on the assumed offering price of $10.00 per share and the assumption
that all warrants to purchase Series A preferred stock will be exercised in
connection with this offering. All shares of our preferred stock will convert
into common stock on a 1-for-1 basis upon completion of this offering. Shares
and warrants held by affiliated persons and entities have been aggregated. See
"Principal Stockholders." In connection with the above transactions, we entered
into an agreement with the investors providing for registration rights with
respect to these shares. See "Description of Capital Stock--Registration
Rights."

   In connection with our acquisition of Windom Health in August 1999, we
issued cash, shares of our common stock and promissory notes to the following
individuals who are directors or executive officers:

  . 1,642,272 shares of common stock, approximately $39,795 in cash and a
    promissory note in the principal amount of $357,684 to Michael D.
    McDonald, the co-chairman of our board of directors;

  . 204,852 shares of common stock, approximately $4,960 in cash and a
    promissory note in the principal amount of $44,617 to Deryk Van Brunt,

    promissory note in the principal amount of $17,792 to Marcos A.
    Athanasoulis, our Vice President of Engineering.

   The amounts due under these promissory notes were paid in full in August
1999. The proceeds from our issuances of promissory notes in 1998 and 1999 were
used for working capital and general corporate purposes.

   In September 1996, we issued 1,152,500 shares to Preview Travel in exchange
for the assignment to us of distribution rights for content produced by Dr.
Dean S. Edell under a contract between Dr. Edell and News Travel Network, which
then was a subsidiary of Preview Travel. These shares were purchased in August
1997 by James J. Hornthal, one of our directors and a holder of 5% or more of
our outstanding stock. Mr. Hornthal is Preview Travel's chairman of its board
of directors and is also chairman of the board of directors of NewsNetCentral,
for which News Travel Network was a predecessor entity.

   In May 1999, we entered into a fifteen-year agreement with Dr. Edell, a
director and 5% stockholder, in which he granted us the exclusive right to the
use of his name in connection with our business and exclusive commercialization
rights to his services over the Internet, except for publication of radio
transcripts and Internet broadcasts of his radio program. Under this agreement,
we own all content that Dr. Edell creates for our HealthCentral.com network.
Dr. Edell has the right to review and reasonably approve all content and
advertising in the Dr. Dean section of our HealthCental.com website. We are not
obligated to make any payments of cash or equity under the terms of this
agreement.

   In August 1999, we entered into a Joint Development Agreement with Global
Health Initiatives, of which Dr. McDonald, one of the co-chairmen of our board
of directors, is the president and chairman of the board. This agreement
provides for our joint collaboration in the performance of services and
development of products, with pricing to be determined and agreed upon by the
parties on a project-by-project basis. Among other provisions, the agreement
provides that, other than with respect to consumer health informatics, we may
not compete with Global Health Initiatives in the areas of:

  . health care systems consulting;

  . enterprise engineering;

  . health information systems; or

  . virtual health management.

   In August 1999, we entered into a services agreement with NewsNet Central
and Dr. Edell, providing for the joint marketing of a consumer health
programming service that will include health-related video clips

                                       65
<PAGE>

produced by Dr. Edell. Mr. Hornthal is the co-chairman of our board of
directors and the chairman of the board of directors of NewsNet Central.

   In February 1999, we granted to Albert L. Greene an option to purchase 4,783
shares of common stock at an exercise price of $0.25 per share, which shares
have fully vested, and an immediately exercisable option to purchase 449,156
shares of common stock at an exercise price of $0.25 per share, which shares
vest over a 36 month period beginning in August 1999. Additionally, in October
1999, we granted to Mr. Greene an option to purchase 44,643 shares of common
stock at an exercise price of $10.08 per share, which shares vest over a 48
month period beginning October 1999.

   In June 1999, we granted to C. Fred Toney immediately exercisable options to
purchase an aggregate of 312,500 shares of our common stock at an exercise
price of $1.28 per share, which shares vest over a 48 month period beginning in
January 1999, the option's vesting commencement date. In connection with
Mr. Toney's early exercise of these options in July 1999, Mr. Toney entered
into restricted stock purchase agreements with us and issued to us promissory
notes in the aggregate principal amount of $400,000 bearing interest at 5.74%
per annum, compounded annually, with principal and interest due upon the
earliest of July 12, 2003 or the termination of Mr. Toney's service provider
relationship with us. Upon his termination, we may purchase unvested shares at
cost. The amount currently outstanding under the promissory notes is $400,000,
plus accrued interest.

   In August 1999, we granted to Marcos A. Athanasoulis an immediately
exercisable option to purchase 62,500 shares of our common stock at an exercise
price of $1.28 per share, which shares vest over a 48 month period beginning in
February 1999. In August 1999, we granted to Deryk Van Brunt an immediately
exercisable option to purchase 100,000 shares of our common stock at an
exercise price of $1.28 per share, which shares vest over a 48 month period
beginning in February 1999, and in September 1999, we granted to Dr. Van Brunt
an option to purchase 25,000 shares of our common stock at an exercise price of
$8.19 per share, which shares vest over a 48 month period beginning in
September 1999. In August 1999, we granted to Ann-Marie Buddrus, our Vice
President of Production, an immediately exercisable option to purchase 62,500
shares of our common stock at an exercise price of $1.28 per share, which
shares vest over a 48 month period beginning in September 1998.

   In October 1999, we granted to Robert M. Cudd, our Vice President of
Marketing, an option to purchase 125,000 shares of our common stock at an
exercise price of $10.08 per share, which shares vest over a 48 month period
beginning in October 1999.

   In August 1999, in connection with the closing of our acquisition of Windom
Health, we entered into a three-year consulting agreement with Michael D.
McDonald, the co-chairman of our board of directors, under which Dr. McDonald
has agreed to provide us with strategic consulting services related to our
institutional business. The consulting agreement provided for an $85,000 bonus
to be paid to him on the closing of our Series B preferred stock financing and
a monthly fee of $5,000 for his provision of consulting services. If we
terminate the consulting agreement without releasing Dr. McDonald from a
noncompetition provision, Dr. McDonald will continue to receive as severance
the monthly fee due for the remainder of the initial term of the consulting
agreement.

   We believe that all of our transactions with affiliates were entered into on
terms and conditions no less favorable to us than those that could have been
obtained from unaffiliated third parties. In addition, transactions with our
affiliates are approved by a majority of our board of directors, including a
majority of our independent and disinterested directors.

   Stock option grants to our directors are described under the caption
"Management--Board Compensation." Stock option grants and restricted stock
awards to Mr. Greene, our Chief Executive Officer, prior to January 1, 1999 are
described under the caption "Management--Executive Compensation." See
"Management--Employment and Consulting Agreements." We have entered into
indemnification agreements with all of our officers and directors. See
"Management--Limitation of Liability and Indemnification Matters." Some of our
shareholders are entitled to have their shares registered by us for resale. See
"Description of Capital Stock--Registration Rights."

                             PRINCIPAL STOCKHOLDERS

   The following table sets forth information known to us with respect to
beneficial ownership of our common stock as of September 30, 1999, as adjusted
to reflect the sale of common stock offered hereby, by:

  .  each person, or group of affiliated persons, known by us to own
     beneficially more than 5% of our outstanding common stock,

  .  each director,

  .  our Chief Executive Officer, and

  .  all directors and executive officers as a group.

   Except as otherwise noted, the address of each person listed in the table is
c/o HealthCentral.com, 6001 Shellmound Street, Suite 800, Emeryville, CA 94608.
Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and includes voting and investment power
with respect to shares. To our knowledge, except under applicable community
property laws or as otherwise indicated, the persons named in the table have
sole voting and sole investment control with respect to all shares beneficially
owned. The applicable percentage of ownership for each stockholder is based on
12,220,631 shares of common stock outstanding as of September 30, 1999 and an
assumed 19,720,631 shares outstanding after the completion of this offering, in
each case together with applicable options for that stockholder. Shares of
common stock issuable upon exercise of options and other rights beneficially
owned that are exercisable on or before November 29, 1999 are deemed
outstanding for the purpose of computing the percentage ownership of the person
holding those options and other rights but are not deemed outstanding for
computing the percentage ownership of any other person. A portion of the shares
issued to officers or issuable upon exercise of options by officers is subject
to repurchase by us at the original exercise price in the event of termination
of that officers' employment, which repurchase right lapses over time.

                          DESCRIPTION OF CAPITAL STOCK

   Upon the completion of this offering, we will be authorized to issue
100,000,000 shares of common stock, $0.001 par value, and 5,000,000 shares of
undesignated preferred stock, $0.001 par value. The following description of
our capital stock does not purport to be complete and is qualified in its
entirety by our certificate of incorporation and bylaws, which are included as
exhibits to the registration statement of which this prospectus forms a part,
and by the provisions of applicable Delaware law.

Common Stock

   As of September 30, 1999, there were 12,220,631 shares of common stock
outstanding, held of record by approximately 52 stockholders, which reflects
the conversion of all outstanding shares of preferred stock into common stock.
Upon completion of this offering, there will be 19,720,631 shares of common
stock outstanding, based upon shares outstanding as of September 30, 1999 and
assuming no exercise of the underwriters' overallotment option or additional
exercise of outstanding options or warrants after September 30, 1999.

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

Preferred Stock

   Upon the closing of the offering, all outstanding shares of preferred stock
will be converted into 5,050,955 shares of common stock and automatically
retired. Thereafter, the board of directors will have the authority, without
further action by the stockholders, to issue up to 5,000,000 shares of
preferred stock in one or more series and to designate the rights, preferences,
privileges and restrictions of each such series. The issuance of preferred
stock could have the effect of restricting dividends on the common stock,
diluting the voting power of the common stock, impairing the liquidation rights
of the common stock or delaying or preventing our change in control without
further action by the stockholders. We have no present plans to issue any
shares of preferred stock.

Warrants

   As of September 30, 1999, warrants were outstanding to purchase an aggregate
of 666,373 shares of common stock at a weighted average exercise price of $2.89
per share. Of these warrants, warrants to purchase an aggregate of 580,228
shares of common stock at a weighted average exercise price of $2.45 per share
will terminate upon the completion of this offering if not exercised prior to
such time. We also have committed to issue to Yahoo!, on or after March 2001, a
warrant to purchase that amount of shares equal to 0.5% of the shares of our
common stock outstanding as of March 2001, assuming the exercise and conversion
of all convertible and exercisable securities outstanding on that date, unless
our content license agreement with Yahoo! is terminated prior to this date.
Under our agreement with AltaVista regarding our co-branded health channel, if
AltaVista meets given performance thresholds, ranging from 25% to 150% based on
the number of impressions delivered in excess of guaranteed minimum amounts, we
will issue warrants to AltaVista to purchase shares of common stock, with the
number of shares depending on the amount by which AltaVista exceeds the
performance thresholds. These warrants will have varying exercise prices.

Registration Rights

   As of September 30, 1999, the holders of 11,382,508 shares of common stock
and warrants to purchase 498,249 shares of common stock are entitled to have
their shares registered by us under the Securities Act under the terms of an
agreement between us and the holders of these "registrable securities." Subject
to limitations specified in the agreement, these registration rights include
the following:

  .  The holders of registrable securities may require, on two occasions
     beginning six months after the date of this offering, that we use our
     best efforts to register the registrable securities for public resale,
     provided that the aggregate offering price for such registrable
     securities is at least $15,000,000. This right is subject to the ability
     of the underwriters to limit the number of shares included in the
     offering in view of market conditions.

  . If we register any common stock, either for our own account or for the
    account of other security holders, the holders of registrable securities
    are entitled to include their shares of common stock in such
    registration. This right is subject to the ability of the underwriters to
    limit the number of shares included in the offering in view of market
    conditions.

  . The holders of registrable securities may require us to register all or a
    portion of their registrable securities on Form S-3 when use of such form
    becomes available to us, provided that the proposed aggregate offering
    price is at least $1,000,000. The holders of registrable securities may
    not exercise this right more than twice in any twelve-month period.

   We will bear all registration expenses other than underwriting discount and
commissions, except in the case of registrations on Form S-3. All registration
rights terminate on the date five years following the closing of this offering,
or, with respect to each holder of registrable securities, at such time as the
holder is entitled to sell all of its shares in any three month period under
Rule 144 of the Securities Act.

   In addition to the registration rights described above, holders of the
shares of our common stock issued to the former HealthCentralRx.com and
RxList.com stockholders in connection with our acquisitions of
HealthCentralRx.com and RxList.com may request that we register their shares to
allow them to resell their shares in the public market on a registration
statement on Form S-1. These demand registration rights may be exercised,
subject to various restrictions, beginning 180 days after the closing of our
initial public offering.

Delaware Anti-Takeover Law and Provisions of our Certificate of Incorporation
and Bylaws

   Provisions of Delaware law and our certificate of incorporation and bylaws
could make more difficult our acquisition by a third party and the removal of
our incumbent officers and directors. These provisions, summarized below, are
expected to discourage coercive takeover practices and inadequate takeover bids
and to encourage persons seeking to acquire control of our company to first
negotiate with us. We believe that the benefits of increased protection of our
ability to negotiate with the proponent of an unfriendly or unsolicited
acquisition proposal outweigh the disadvantages of discouraging such proposals
because, among other things, negotiation could result in an improvement of
their terms.

   We are subject to Section 203 of the Delaware General Corporation Law, which
regulates corporate acquisitions. In general, Section 203 prohibits a publicly
held Delaware corporation from engaging in a business combination with an
interested stockholder for a period of three years following the date the
person became an interested stockholder, unless:

  . the board of directors approved the transaction in which such stockholder
    became an interested stockholder prior to the date the interested
    stockholder attained such status;

  . upon consummation of the transaction that resulted in the stockholder's
    becoming an interested stockholder, he or she owned at least 85% of the
    voting stock of the corporation outstanding at the time the transaction
    commenced, excluding shares owned by persons who are directors and also
    officers; or

                                       70
<PAGE>

  . on or subsequent to such date the business combination is approved by the
    board of directors and authorized at an annual or special meeting of
    stockholders.

   A business combination generally includes a merger, asset or stock sale, or
other transaction resulting in a financial benefit to the interested
stockholder. In general, an interested stockholder is a person who, together
with affiliates and associates, owns, or within three years prior to the
determination of interested stockholder status, did own, 15% or more of a
corporation's voting stock.

   Our certificate of incorporation and bylaws do not provide for the right of
stockholders to act by written consent without a meeting or for cumulative
voting in the election of directors. In addition, our certificate of
incorporation permits the board of directors to issue preferred stock with
voting or other rights without any stockholder action. Our certificate of
incorporation provides for the board of directors to be divided into three
classes, with staggered three-year terms. As a result, only one class of
directors will be elected at each annual meeting of stockholders. Each of the
two other classes of directors will continue to serve for the remainder of its
respective three-year term. These provisions, which require the vote of
stockholders holding at least two-thirds of the outstanding common stock to
amend, may have the effect of deterring hostile takeovers or delaying changes
in our management.

Transfer Agent and Registrar

   The transfer agent and registrar for the common stock is U.S. Stock Transfer
Corporation. The Transfer Agent's address and telephone number is 1745 Gardena
Avenue, Glendale, CA, 91204 (818) 502-1404.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no market for our common stock.
Future sales of substantial amounts of common stock in the public market could
adversely affect prevailing market prices. As described below, no shares
currently outstanding will be available for sale immediately after this
offering because of contractual restrictions on resale. Sales of substantial
amounts of our common stock in the public market after the restrictions lapse
could adversely affect the prevailing market price and impair our ability to
raise equity capital in the future.

   Upon completion of the offering, we will have 19,720,631 outstanding shares
of common stock, based upon shares outstanding as of September 30, 1999 and
assuming no exercise of options or warrants. Of these shares, the 7,500,000
shares sold in the offering, plus any shares issued upon exercise of the
underwriters' overallotment option, will be freely tradable without restriction
under the Securities Act, unless purchased by our "affiliates" as that term is
defined in Rule 144 under the Securities Act. In general, affiliates include
officers, directors or 10% stockholders.

   The remaining 12,220,631 shares outstanding are "restricted securities"
within the meaning of Rule 144. Restricted securities may be sold in the public
market only if registered or if they qualify for an exemption from registration
promulgated under the Securities Act. Sales of the restricted securities in the
public market, or the availability of such shares for sale, could adversely
affect the market price of the common stock.

   Our directors, officers and stockholders have entered into lock-up
agreements in connection with this offering generally providing that they will
not offer, sell, contract to sell or grant any option to purchase or otherwise
dispose of our common stock or any securities exercisable for or convertible
into our common stock owned by them for a period of 180 days after the date of
this prospectus without the prior written consent of Lehman Brothers Inc.
Notwithstanding possible earlier eligibility for sale under exemptions from
registration promulgated under the Securities Act, shares subject to lock-up
agreements will not be salable until such agreements expire or are waived by
Lehman Brothers Inc. Taking into account the lock-up agreements, and assuming
Lehman Brothers Inc. does not release stockholders from these agreements, the
following shares will be eligible for sale in the public market at the
following times:

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

  . Beginning 180 days after the effective date, approximately 4,899,906
    shares will be eligible for sale. All but 900,000 of such shares are held
    by affiliates.

  . Between 180 days and 365 days after the effective date, approximately
    6,168,225 shares will be eligible for sale under Rule 144 at various
    times. All but 3,432,732 shares are held by affiliates.

  . Beginning 365 days after the effective date, approximately 1,152,500
    additional shares will be eligible for sale under Rule 144. All of these
    shares are held by Dr. Dean Edell, an affiliate, and are subject to an
    agreement with us preventing the sale or other transfer of these shares
    for a period of 365 days from the effective date of this offering.

   In general, under Rule 144 as currently in effect, after the expiration of
the lock-up agreements, a person who has beneficially owned restricted
securities for at least one year would be entitled to sell within any three-
month period a number of shares that does not exceed the greater of:

  . one percent of the number of shares of common stock then outstanding,
    which will equal approximately 197,206 shares immediately after the
    offering, based upon shares outstanding as of September 30, 1999 and
    assuming no exercise of options or warrants; or

  . the average weekly trading volume of the common stock during the four
    calendar weeks preceding the sale.

                                       72
<PAGE>

   Sales under Rule 144 are also subject to requirements with respect to manner
of sale, notice, and the availability of current public information about us.

   Rule 701, as currently in effect, permits our employees, officers, directors
or consultants who purchased shares pursuant to a written compensatory plan or
contract to resell such shares in reliance upon Rule 144 but without compliance
with specific restrictions. Rule 701 provides that affiliates may sell their
Rule 701 shares under Rule 144 without complying with the holding period
requirement and that non-affiliates may sell such shares in reliance on Rule
144 without complying with the holding period, public information, volume
limitation or notice provisions of Rule 144.

   In addition, we intend to file a registration statement under the Securities
Act as promptly as possible after the effective date to register shares to be
issued pursuant to our employee benefit plans. As a result, any options or
rights exercised under the 1999 stock plan, the HealthCentralRx.com 1999 stock
option plan, the 1998 stock plan, the 1999 employee stock purchase plan, the
1999 directors' stock option plan or any other benefit plan after the
effectiveness of the registration statement will also be freely tradable in the
public market. However, such shares held by affiliates will still be subject to
the volume limitation, manner of sale, notice and public information
requirements of Rule 144 unless otherwise resalable under Rule 701. As of
September 30, 1999, there were outstanding options for the purchase of
2,006,157 shares of common stock.

</TABLE>

   The underwriting agreement provides that the underwriters' obligations to
purchase shares of common stock depend on the satisfaction of the conditions
contained in the underwriting agreement, and that if any of the shares of
common stock are purchased by the underwriters under the underwriting
agreement, then all of the shares of common stock which the underwriters have
agreed to purchase under the underwriting agreement must be purchased. The
conditions contained in the underwriting agreement include the requirement that
the representations and warranties made by us to the underwriters are true,
that there is no material change in the financial markets and that we deliver
to the underwriters customary closing documents.

   The following table shows the per share and total underwriting discounts and
commissions to be paid to the underwriters by us. These amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase 1,125,000 additional shares.

   The representatives have advised us that the underwriters propose to offer
the shares of common stock directly to the public at the public offering price
set forth on the cover page of this prospectus, and to dealers, who may include
the underwriters, at the public offering price less a selling concession not in
excess of $   share. The underwriters may allow, and the dealers may reallow, a
concession not in excess of $   per share to brokers and dealers. After the
offering, the underwriters may change the offering price and other selling
terms.

   We have granted to the underwriters an option to purchase up to an aggregate
of 1,125,000 additional shares of common stock, exercisable solely to cover
over-allotments, if any, at the public offering price less the underwriting
discounts and commissions shown on the cover page of this prospectus. The
underwriters may exercise this option at any time until 30 days after the date
of the underwriting agreement. If this option is exercised, each underwriter
will be committed, so long as the conditions of the underwriting agreement are
satisfied, to purchase a number of additional shares of common stock
proportionate to the underwriter's initial commitment as indicated in the
preceding table and we will be obligated, under the over-allotment option, to
sell the shares of common stock to the underwriters.

   We have agreed that, without the prior consent of Lehman Brothers Inc., we
will not directly or indirectly offer, sell or otherwise dispose of any shares
of common stock or any securities which may be converted into or exchanged for
any such shares of common stock for a period of 180 days from the date of this
prospectus. All of our executive officers and directors and certain other
stockholders, including all of the holders of the preferred stock and warrants,
have agreed under lock-up agreements that, without the prior written consent of

                                       74
<PAGE>

Lehman Brothers Inc., they will not, directly or indirectly, offer, sell or
otherwise dispose of any shares of common stock or any securities which may be
converted into or exchanged for any such shares for the period ending 180 days
after the date of this prospectus. Please see "Shares Eligible for Future
Sale."

   Prior to the offering, there has been no public market for the shares of
common stock. The initial public offering price has been negotiated between the
representatives and us. In determining the initial public offering price of the
common stock, the representatives will consider, among other things and in
addition to prevailing market conditions, our historical performance and
capital structure, estimates of our business potential and earning prospects,
an overall assessment of our management and the consideration of the above
factors in relation to market valuation of companies in related businesses.

   We have applied to the Nasdaq National Market for listing approval under the
symbol "HCEN."

   We have agreed to indemnify the underwriters against liabilities, including
liabilities under the Securities Act of 1933 and liabilities arising from
breaches of the representations and warranties contained in the underwriting
agreement, and to contribute to payments that the underwriters may be required
to make for these liabilities.

   We estimate that the total expenses of the offering, excluding underwriting
discounts and commissions, will be approximately $1.5 million.

   Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters
and selling group members to bid for and purchase shares of common stock. As an
exception to these rules, the representatives are permitted to engage in
transactions that stabilize the price of the common stock. These transactions
may consist of bids or purchases for the purposes of pegging, fixing or
maintaining the price of the common stock.

   The underwriters may create a short position in the common stock in
connection with the offering, which means that they may sell more shares than
are set forth on the cover page of this prospectus. If the underwriters create
a short position, then the representatives may reduce that short position by
purchasing common stock in the open market. The representatives also may elect
to reduce any short position by exercising all or part of the over-allotment
option.

   The underwriters have informed us that they do not intend to confirm sales
to discretionary accounts that exceed 5% of the total number of shares of
common stock offered by them.

   The representatives also may impose a penalty bid on underwriters and
selling group members. This means that if the representatives purchase shares
of common stock in the open market to reduce the underwriters' short position
or to stabilize the price of the common stock, they may reclaim the amount of
the selling concession from the underwriters and selling group members who sold
those shares as part of the offering.

   In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of those purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
an offering.

   Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the common stock. In addition, neither
we nor any of the underwriters makes any representation that the
representatives will engage in these transactions or that these transactions,
once commenced, will not be discontinued without notice.

                       Report of Independent Accountants

   The stock split described in Note 1 to the financial statements has not been
consummated at November 30, 1999. When it has been consummated, we will be in a
position to furnish the following report:

"To the Board of Directors and Stockholders of
HealthCentral.com

   In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash
flows present fairly, in all material respects, the financial position of
HealthCentral.com (a development stage company) and its subsidiary at December
31, 1997 and 1998 and September 30, 1999, and the results of their operations
and their cash flows for the period from August 12, 1996 (date of inception) to
December 31, 1996, and for each of the two years ended December 31, 1998 and
the nine months ended September 30, 1999, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audits to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statements presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above."

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 The Company

   HealthCentral.com (the "Company") was incorporated in California on August
12, 1996. The Company commenced operations in 1998 and provides online
healthcare information and products to consumers through the Company's
HealthCentral.com network. The Company operates in one business segment.

   In November 1999, the Company reincorporated in the state of Delaware. Also
in November 1999, the Board of Directors and shareholders of the Company
approved a 5-for-4 stock split of its common and preferred stock, which will be
effected prior to the completion of the offering.

   The Company has a limited operating history and its prospects are subject to
risks, expenses and uncertainties frequently encountered by companies in the
new and rapidly evolving markets for Internet products and services. These
risks include the failure to develop and expand the Company's online brands,
the rejection of the Company's products and services by Internet consumers,
vendors and/or advertisers, the inability of the Company to maintain and
increase the levels of traffic on its HealthCentral.com network of websites, as
well as other risks and uncertainties.

 Principles of consolidation and basis of presentation

   The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary, Windom Health Enterprises, Inc. All
significant intercompany balances and transactions have been eliminated in
consolidation.

 Development stage enterprise

   For the period from inception through September 30, 1999, the Company was a
development stage company, as planned principal operations had not yet begun to
generate significant revenue. In the development stage, all pre-operating costs
have been expensed as incurred.

 Use of estimates

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

 Interim financial statements (unaudited)

   The consolidated financial statements for the nine months ended September
30, 1998 are unaudited and should be read in conjunction with the Company's
annual financial statements for the year ended December 31, 1998. Such interim
financial statements have been prepared in conformity with the rules and
regulations of the Securities and Exchange Commission. Certain disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to such
rules and regulations pertaining to interim financial statements. In the
opinion of management, all adjustments (consisting of normal recurring
adjustments) necessary for a fair presentation have been included. The results
of operations of any interim period are not necessarily indicative of the
results of operations for the full year.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


 Cash and cash equivalents

   The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. The Company maintains
its cash in bank deposit accounts which, at times, may exceed federally insured
limits.

 Property and equipment

   Property and equipment are recorded at cost. Depreciation and amortization
are computed on a straight-line basis over the estimated useful lives of the
assets, as follows:

<TABLE>
   <S>                                                                 <C>
   Computer and network equipment .................................... 2-3 years
   Furniture and office equipment.....................................   5 years
</TABLE>

   Leasehold improvements are amortized on a straight-line basis over the life
of the lease, or the useful life of the assets, whichever is shorter.

 Impairment of long-lived assets

   The Company evaluates the recoverability of long-lived assets in accordance
with Statement of Financial Accounting Standards No. ("SFAS") 121. "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed of " . SFAS No. 121 requires recognition of impairment of long-lived
assets in the event the net book value of such assets exceeds the future
undiscounted cash flows attributable to such assets.

 Intangible assets

   Intangible assets consist primarily of goodwill, which is being amortized on
a straight line basis over three years.

   The Company considers potential impairments of its intangible assets on an
exception basis when evidence exists that events or changes in circumstances
may have made recovery of the carrying value unlikely. An impairment loss is
recognized when the expected undiscounted future net cash flows is less than
the carrying amount of the asset. No such losses have been identified to date.

 Pro forma stockholders' equity

   The pro forma stockholders' equity as of September 30, 1999 reflects the
conversion of all outstanding shares of convertible preferred stock into an
aggregate of 5,050,955 shares of common stock.

 Comprehensive income

   The Company adopted the provisions of SFAS No. 130, "Reporting Comprehensive
Income". This statement requires companies to classify items of other
comprehensive income by their nature in the financial statements and display
the accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of the balance
sheet. To date, the Company has not had any transactions that are required to
be reported in comprehensive income.

 Revenue recognition

   The Company records advertising revenues in the period the advertising
impressions are delivered to customers. The Company uses an outside vendor to
solicit customers to use its advertising services, to serve the

ads to its website and to bill and collect for these services. This outside
vendor provides monthly reports indicating the impressions delivered, amounts
billed for the Company's advertising services and the related administrative
fee. The Company records advertising revenues, as reported by the outside
vendor, net of this administrative fee as the Company bears no collection risk
for the gross amount of the advertising fees. The Company's advertising
contracts do not guarantee a minimum number of impressions to be delivered.

 Advertising expenses

   Internet advertising expenses are recognized based on the terms of the
individual agreements, but generally over the greater of the ratio of the
number of impressions received over the total number of contracted impressions,
or on a straight-line basis over the term of the contact. There were no
advertising expenses for the period from inception to December 31, 1996 or the
years ended December 31, 1997 and 1998. Advertising expense for the nine months
ended September 30, 1999 was $992,486 and has been included in sales and
marketing expense in the consolidated statement of operations.

 Net loss per share

   The Company computes net loss per share in accordance with SFAS No. 128,
"Earnings per Share" and SEC Staff Accounting Bulletin No. 98. Basic and
diluted net loss per share are computed by dividing the net loss available to
holders of common stock for the period by the weighted average number of shares
of common stock outstanding during the period. The calculation of diluted net
loss per share excludes potential common stock if their effect is antidilutive.
Potential common stock consists of restricted common stock, incremental common
shares issuable upon the exercise of stock options and warrants and shares
issuable upon conversion of the Series A and B convertible preferred stock.

   The following table sets forth potential shares of common stock that are not
included in the diluted net loss per share because to do so would be
antidilutive for the periods indicated:

lapse.

 Pro forma net loss per share (unaudited)

   Pro forma net loss per share for the year ended December 31, 1998 and the
nine months ended September 30, 1999 are computed using the weighted average
number of shares of common stock outstanding, including the pro forma effects
of the automatic conversion of the Company's Series A and Series B convertible
preferred stock into shares of the Company's common stock effective upon the
closing of the Company's initial public offering as if such conversion occurred
on January 1, 1998, or at the date of original issuance, if later. The
resulting pro forma adjustment includes an increase in the weighted average
shares used to compute pro forma basic net loss per share for the year ended
December 31, 1998 and the nine months ended September 30, 1999. The calculation
of pro forma diluted net loss per share excludes potential shares of common
stock as their effect would be antidilutive.

 Income taxes

   Deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax basis of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary
to reduce deferred tax assets to the amounts expected to be realized.

 Financial instruments

   Carrying amounts of certain of the Company's financial instruments,
including cash and cash equivalents, accounts receivable, accrued liabilities
and accounts payable, approximate fair value due to their short maturities.

 Stock options

   The Company accounts for employee stock compensation arrangements in
accordance with provisions of Accounting Principles Board Opinion ("APB") No.
25, "Accounting for Stock Issued to Employees," and complies with the
disclosure provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation." Under APB No. 25, stock compensation is based on the difference,
if any, on the date of grant, between the estimated fair value of the Company's
common stock and the exercise price. Deferred stock compensation is amortized
in accordance with Financial Accounting Standards Board ("FASB") Interpretation
No. ("FIN") 28. The Company accounts for stock issued to non-employees in
accordance with the provisions of SFAS No. 123 and Emerging Issues Task Force
Issue No. 96-18, "Accounting for Equity Instruments that are Issued to Other
than Employees for Acquiring, or in Conjunction with Selling, Goods or
Services."

 New accounting pronouncements

   In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivatives and
Hedging Activities." SFAS No. 133 establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. In July 1999, the FASB
issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities--Deferral of the Effective Date of FASB Statement No. 133." SFAS No.
137 deferred the effective date of SFAS No. 133 until fiscal years beginning
after June 15, 2000. The Company will adopt SFAS No. 133 during its year ending
December 31, 2001. To date, the Company has not engaged in derivative or
hedging activities.

NOTE 3--ACQUISITION OF WINDOM HEALTH ENTERPRISES, INC.:

   On May 6, 1999, the Company entered into a definitive merger agreement with
Windom Health Enterprises, Inc. ("Windom Health") and completed the merger on
August 12, 1999. Windom Health is engaged in offering institutions the ability
to license specialized tools and services to provide their members with
personalized online health information and health risk assessments.

   This transaction was recorded using the purchase method of accounting. The
allocation of the aggregate purchase price to the tangible and identifiable
intangible assets acquired and liabilities assumed in connection with this
acquisition was based on estimated fair values as determined by management. The
allocation is summarized below:

<TABLE>
   <S>                                                              <C>

   Acquired workforce..............................................     180,000
   In-process research and development.............................     555,000

</TABLE>

   The total purchase price of $12.7 million consisted of cash of $51,000, a
note payable of $458,000, 2,104,770 shares of the Company's common stock valued
at $9,311,514, assumed liabilities of $2,868,457 and estimated transaction
costs of $65,000. The deemed value of the Company's common stock on the date
the definitive merger agreement was signed was $4.42 per share.

   The valuation of the purchased in-process research development of $555,000
was based on the result of an independent appraisal using the income approach.
The income approach estimates the value of the asset based on its expected
economic benefit. The valuation analysis considered the contribution of the
core technology as well as the percentage of completion of the in-process
research and development. The expected cash flows associated with the in-
process research and development were discounted to the present value using a
rate of return that is commensurate with the risk of the asset. The purchased
in-process technology was not considered to have reached technological
feasibility and had no alternative future use.

NOTE 4--RELATED PARTY TRANSACTIONS:

   In August 1998, in association with a letter of intent relating to the
merger with Windom Health, the Company entered into a License and Management
Agreement (the "Agreement") with Windom Health. Pursuant to the Agreement, the
Company had full management responsibility for the operations of Windom Health.
In this capacity, the Company advanced Windom Health funds to finance its
operations. At December 31, 1998, the net outstanding balance due from Windom
Health amounted to $563,541. The cumulative amount due from Windom Health at
the merger date (August 12, 1999) was eliminated in consolidation.

   In April 1999, the Company borrowed an amount of $500,000 in the form of
convertible notes from a related party. The notes bore interest at 4.99% per
annum. In August 1999, the notes were canceled upon the issuance of 96,153
shares of the Company's Series B convertible preferred stock at $5.20 per
share. In August 1999, the Company borrowed an additional $300,000 under the
same agreement. The new notes bore interest at the rate of ten percent per
annum. In connection with this additional borrowing the Company issued warrants
to purchase 8,333 shares of the Company's Series B convertible preferred stock
at an exercise price of $3.60 per share. The warrants expire at the earlier of
(a) August 2002, (b) the closing of an acquisition or (c) the effective date of
the Company's initial public offering. The Company valued the warrants using
the Black-Scholes option pricing model using an expected life of two years, a
weighted average risk-free rate of 5.76% an expected dividend yield of zero
percent, a volatility of 70% and a deemed value of the common stock of $7.39
per share. The estimated fair value of the warrants of $39,008 was amortized
over the period of the borrowing agreement until the notes were canceled in
August 1999 upon the issuance of 57,691 shares of the Company's Series B
convertible stock at $5.20 per share.

   In July 1999, the Company borrowed $100,000 from an officer in the Company
pursuant to a convertible promissory note. The note bears interest at the rate
of ten percent per annum. In August 1999, the note was cancelled upon the
issuance of 19,230 shares of the Company's Series B convertible preferred stock
at $5.20 per share.

   In July 1999, the Company borrowed an aggregate of $600,000 from four
stockholders in the form of promissory notes. The notes bear interest at the
rate of ten percent per annum. In connection with these notes, the Company
issued warrants to purchase an aggregate of 16,664 shares of the Company's
common stock at $3.60 per share. The warrants expire upon the earliest of (a)
July 1, 2003, (b) the closing of an acquisition, or (c) immediately prior to
the effective date of the Company's registration statement under the Securities
Act of 1933 with respect to an initial public offering. The Company valued the
warrants using the Black-Scholes

average risk-free rate of 5.7%, an expected dividend yield of zero percent, a
volatility of 70% and deemed values of common stock of $6.07 and $6.92 per
share. The estimated fair value of the warrants of $64,017 was amortized over
the period the notes became exercisable and included within interest expense in
the statement of operations. In August 1999, the notes were canceled upon the
issuance of 115,383 shares of the Company's Series B convertible preferred
stock at $5.20 per share.

   In August 1999 in connection with the acquisition of Windom Health, the
Company entered into a three-year consulting agreement with Michael D.
McDonald, a member of the Board of Directors, which provided for an $85,000
bonus to be paid to him on the closing of the Company's Series B preferred
stock financing and a monthly fee of $5,000 for consulting services. If the
Company terminates the consulting agreement without releasing Dr. McDonald from
its noncompetition provision, Dr. McDonald will continue to receive, as
severance, the monthly fee due for the remainder of the initial term of the
consulting agreement.

   The holders of preferred stock have various rights and preferences as
follows:

 Voting

   Each share of Series A and Series B convertible preferred stock has voting
rights equal to an equivalent number of shares of common stock into which it is
convertible and votes together as one class with the common stock.

   As long as at least 1,250,000 shares of convertible preferred stock remain
outstanding, the Company must obtain approval from a majority of the holders of
convertible preferred stock in order to alter the Articles of Incorporation as
they relate to convertible preferred stock, authorize a dividend for any class
or series other than convertible preferred stock, create a new class of stock
or effect a merger, consolidation or sale of assets where the existing
shareholders retain less than 50% of the voting stock of the surviving entity.

 Dividends

   Holders of Series A and Series B convertible preferred stock are entitled to
receive noncumulative dividends at the per annum rate of $0.13 and $0.33 per
share respectively, when and if declared by the Board of Directors. The holders
of Series A and Series B convertible preferred stock are entitled to
participate in dividends on common stock, when and if declared by the Board of
Directors, based on the number of shares of common stock held on an as-if
converted basis. No dividends on convertible preferred stock or common stock

own less than 51% of the resulting voting power of the surviving entity, the
holders of Series A and Series B convertible preferred stock are entitled to
receive an amount of $2.00 and $5.20 per share respectively, plus any declared
but unpaid dividends, prior to and in preference to any distribution to the
holders of common stock. The remaining assets, if any, shall be distributed
ratably to the common stockholders. Should the Company's legally available
assets be insufficient to satisfy the liquidation preferences, the funds will
be distributed ratably to the Series A and Series B convertible preferred
stockholders.

 Conversion

   Each share of Series A and Series B convertible preferred stock is
convertible into shares of the Company's common stock, at the option of the
holder, on a one to one basis subject to adjustment for dilution. Each share of
Series A and Series B convertible preferred stock automatically converts into
the number of shares of common stock into which such shares are convertible at
the then effective conversion ratio upon (1) the closing of a public offering
of common stock in which the pre-money valuation of the Company, as defined in
the Articles of Incorporation, is at least $125 million with gross proceeds of
at least $15,000,000, (2) a merger, sale of substantially all of the assets or
other transactions which result in a change in control, or (3) the consent of
66 2/3% of convertible preferred stock.

 Warrants for convertible preferred stock

   In connection with the sale of Series A convertible preferred stock in
December 1998, the Company issued 486,000 shares of Series A convertible
preferred stock at an exercise price of $2.00 per share. These warrants are
outstanding and exercisable at December 31, 1998 and expire in five years. The
Company valued the warrants using the Black-Scholes option pricing model,
applying an expected life of five years, a weighted average risk-free rate of
4.36%, an expected dividend yield of zero percent, a volatility of 70% and a
deemed value of common stock of $1.52 per share. The estimated fair value of
the warrants of $408,629 has been netted against the proceeds of the offering.

   In May 1999, in connection with entering into facility leases, the Company
issued an aggregate of 12,249 Series A convertible preferred stock warrants at
an exercise price of $2.00 per share. The warrants expire at the earlier of (a)
two years following the closing of an initial public offering, or (b) May 2009.
The Company valued the warrants using the Black-Scholes option pricing model,
applying an expected life of ten years, a weighted average risk free rate of
5.39%, an expected dividend yield of zero percent, a volatility of 70% and a
deemed value of common stock of $4.59 per share. The fair value of the warrants
of $49,372 is being amortized over the period of the leases.

   In August, 1999, in connection with investment banking services provided
during the Series B preferred stock offering, the Company issued warrants to
purchase an aggregate of 69,231 shares of Series B preferred stock at an
exercise price of $5.20 per share. The warrants expire at the earlier of (a)
August 2001 (b) the closing of an acquisition or (c) immediately prior to the
effective date of the Company's registration statement under the Securities Act
of 1933 with respect to an initial public offering. The Company valued the
warrants using the Black-Scholes option pricing model, applying an expected
life of two years, a weighted average risk-free rate of 5.74%, an expected
dividend yield of zero percent, a volatility of 70% and a deemed value of
common stock of $7.95. The estimated fair value of the warrants of $301,317 was
netted against the proceeds from the offering.

Company subject to vesting over a one year period. At September 30, 1998,
there were 312,500 shares subject to this repurchase provision at the original
issuance price.

   In April 1999, in connection with a content license agreement, the Company
issued a warrant to purchase 73,896 shares of the Company's common stock at an
exercise price of $6.50 per share. The warrant is exercisable at the earlier
of a) May 2002, b) the one year anniversary of an initial public offering, c)
the sale of 50% of the Company's equity, or d) the date of termination of the
content license agreement or the date in which all of the Company's material
is removed from the website according to the agreement. The Company valued the
warrant using the Black-Scholes option pricing model, applying an expected
life of three years, a weighted average risk-free rate of 5.43%, an expected
dividend yield of zero percent, an expected volatility of 70% and a deemed
value of common stock of $4.97 per share. The fair value of the warrant of
$155,301 is being amortized over the period of the content license agreement.

   In June 1999, the Company granted an officer immediately exercisable
options to purchase as aggregate of 312,500 shares of common stock at an
exercise price of $1.28 per share. In July 1999, in connection with the
exercise of these options, the officer issued a promissory note in the amount
of $400,000 bearing interest at the rate of 5.74% per annum, due upon the
earlier of July 12, 2003 or the termination of employment. Under the
restricted stock purchase agreement, 100% of the shares exercised are
initially subject to repurchase and held in escrow by the Company. The shares
will be released from the repurchase option in accordance with the original
vesting schedule of the underlying common stock option grant.

NOTE 7--STOCK OPTION PLAN:

   In August 1998, the Company adopted the 1998 Stock Option Plan (the "1998
Plan"). The 1998 Plan provides for the granting of stock options to employees
and consultants of the Company. Options granted under the 1998 Plan may be
either incentive stock options or nonqualified stock options. Incentive stock
options ("ISO") may be granted only to employees (including officers and
directors who are also employees). Nonqualified stock options ("NSO") may be
granted to employees and consultants. An aggregate of 3,000,000 shares of
common stock have been reserved for issuance under the 1998 Plan.

   Options under the 1998 Plan may be granted for periods of up to ten years
and at prices no less than 85% of the estimated fair value of the shares on
the date of grant as determined by the Board of Directors, provided, however,
that a) the exercise price of an ISO and NSO shall not be less than 100% and
85% of the estimated fair value of the shares on the date of grant,
respectively, and b) the exercise price of an ISO and NSO granted to a 10%
stockholder shall not be less than 110% of the estimated fair value of the
shares on the date of grant.

   In August 1999, the Company adopted the 1999 Stock Option Plan (the "1999
Plan"). The 1999 Plan provides for the grant of incentive stock options to
employees, including employee directors, and of nonstatutory stock options and
stock purchase rights to employees, directors (including employee directors)
and consultants. At the time of adoption, 250,000 shares of common stock were
reserved for issuance under the 1999 Plan. The 1999 Plan was amended by the
Board of Directors in September 1999 to increase the total number of shares
reserved for issuance by 4,375,000 shares, and to incorporate certain other
changes, after which a total of 4,625,000 shares of common stock have been
reserved for issuance under the 1999 Plan.

   On October 5, 1999, the Company acquired HealthCentralRx.com, Inc.
HealthCentralRx.com operates an online drug store which provides retail sales
of prescription pharmaceuticals, over-the-counter products and health and
beauty aids on the Internet.

   This transaction was recorded using the purchase method of accounting. The
allocation of the aggregate purchase price to the tangible and identifiable
intangible assets acquired and liabilities assumed in connection with this
acquisition was based on estimated fair values as determined by management. The
preliminary purchase price allocation, which is subject to adjustment after the
closing date, is summarized below:

</TABLE>

   The total purchase price of $15,888,000 consisted of 1,492,096 shares of
common stock valued at $13,533,000 based upon the deemed value of the Company's
common stock of $9.07 per share on the date the definitive merger agreement was
signed. The purchase price also included the assumption of 86,969 employee
stock options valued at $6.11 per share, assumed liabilities of $1,653,000 and
estimated transaction costs of $171,000.

   The valuation of the purchased in-process research development of $250,000
was based on the result of an independent appraisal using the income approach.
The income approach estimates the value of the asset based on its expected
economic benefit. The valuation analysis considered the contribution of the
core technology as well as the percentage completion of the in-process research
and development. The expected cash flows associated with the in-process
research and development were discounted to the present value using a rate of
return that is commensurate with the risk of the asset. The purchased
in-process technology was not considered to have reached technological
feasibility and had no alternatives future use.

   Goodwill and other intangibles are being amortized on a straightline basis
over the estimated period of benefit of two to three years.

   On October 28, 1999, the Company acquired RxList.com. RxList.com maintains a
website that allows visitors to search for information regarding prescription
and other medications.

   This transaction was recorded using the purchase method of accounting. The
allocation of the purchase price to the tangible and identifiable intangible
assets acquired and liabilities assumed in connection with this acquisition was

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 The Company

   Windom Health Enterprises, Inc. (the "Company") was formed in 1984 and was
incorporated in California in 1988. The Company provides institutions,
including healthcare organizations, employers and pharmaceutical companies
specialized tools and services for the design, hosting and maintenance of
private label websites. In August 1999, the Company merged with
HealthCentral.com (See Note 5).

 Use of estimates

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

 Interim financial statements (unaudited)

   The financial statements as of June 30, 1999 and for the six months ended
June 30, 1998 and 1999 are unaudited and should be read in conjunction with the
Company's annual financial statements for the year ended December 31, 1998.
Such interim financial statements have been prepared in conformity with the
rules and regulations of the Securities and Exchange Commission. Certain
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations pertaining to interim financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring adjustments) necessary for a fair presentation have been included.
The results of operations of any interim period are not necessarily indicative
of the results of operations for the full year.

 Revenue recognition

   Institutional revenues derived from contracts with healthcare providers,
health product resellers, and third party organizations principally consist of
license fees for website development applications, consulting fees from custom
website development and hosting and maintenance fees related to the websites
maintenance. The Company recognizes software license revenue under Statement of
Position ("SOP") 97-2, Software Revenue Recognition, and SOP 98-9,
Modifications of SOP 97-2, Software Revenue Recognition, with Respect to
Certain Transactions. When contracts contain multiple elements and vendor-
specific objective evidence exists for all undelivered elements, the Company
accounts for the delivered elements in accordance with the "Residual Method"
prescribed by SOP 98-9. To date, vendor-specific objective evidence has not
been available for all undelivered elements and, accordingly, the Company has
recognized the revenues from licenses, hosting and maintenance ratably over the
term of the agreement, generally 12 to 24 months. For consulting projects,
revenues are recognized at the time services are rendered based on charges for
time and materials. Deferred revenues represent the amount of cash received or
invoices rendered prior to revenue recognition.

 Production, content and product development expense

   Production, content and product development expenses consist primarily of
salaries and benefits, consulting fees and other costs related to content
acquisition and licensing, software development, application development and
website operations.

   Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting for
the Costs of Computer Software to be Sold, Leased or Otherwise Marketed"
requires capitalization of certain software development costs subsequent to the
establishment of technological feasibility. To date, costs incurred following
the establishment of technological feasibility, but prior to general product
release, have been insignificant.

 Concentration of credit risk

   Financial instruments that potentially subject the Company to a
concentration of credit risk consist of cash and accounts receivable. The
Company's accounts receivable are derived from revenues earned from customers
located in the U.S. The Company performs ongoing credit evaluation of its
customers' financial condition and, generally, requires no collateral from its
customers. The Company maintains an allowance for doubtful accounts receivable
based upon the expected collectibility of accounts receivable.

   The Company has the following concentrations of revenues and trade accounts
receivables:

</TABLE>

 Financial instruments

   Carrying amounts of certain of the Company's financial instruments,
including accounts receivable, accounts payable, accrued expenses and other
liabilities approximate fair value due to their short maturities. Based upon
borrowing rates currently available to the Company for leases with similar
terms, the carrying value of capital lease obligations approximate fair value.

 Property and equipment

   Property and equipment are recorded at cost and are depreciated using the
straight-line method over the estimated useful lives which range from three to
five years. Leasehold improvements and equipment held under capital leases are
amortized using the straight-line method over the term of the lease or
estimated useful lives, whichever is shorter. Repairs and maintenance costs are
charged to expense when incurred. When assets are sold or retired, the cost and
the related accumulated depreciation are removed from the accounts, and any
resulting gain or loss is included in operations.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


 Impairment of long-lived assets

   The Company evaluates the recoverability of long-lived assets in accordance
with Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of"
("SFAS No. 121"). SFAS No. 121 requires recognition of impairment of long-lived
assets in the event the net book value of such assets exceeds the future
undiscounted cash flows attributable to such assets.

 Income taxes

   The Company elected to be treated as an S corporation for federal and
California income tax purposes in 1992. As a result, minimal income taxes were
payable at the corporate level. Rather, the Company's shareholders included
their respective portions of the Company's taxable income in their individual
income tax returns. On August 12, 1999, in connection with the merger with
HealthCentral.com, the Company became subject to the C corporation provisions
of the Internal Revenue Code. Accordingly, any earnings after this date will be
taxed at HealthCentral's federal and state corporate income tax rates.

   In August 1998, in association with the letter of intent relating to the
merger (Note 5), the Company entered into a License and Management Agreement
with HealthCentral.com. Pursuant to the agreement, HealthCentral.com had full
management responsibility for the operations of the Company. In this capacity,
HealthCentral.com advanced the Company funds to finance its operations. At
December 31, 1998 and June 30, 1999, the net amount due to HealthCentral.com
was $563,541 and $1,361,730 (unaudited), respectively.

   At December 31, 1997 and 1998 and June 30, 1999, the Company had an
outstanding balance of $53,539, $79,500 and $79,500 (unaudited), respectively,
due to a shareholder for past consulting services. This amount was repaid
concurrent with the merger. The Company also paid an additional $27,500 to the
shareholder for consulting services in 1998.

   Shareholder notes payable of $10,500 and $70,500 at December 31, 1997 and
1998, respectively, relate to advances made to the Company from a shareholder
to fund the Company's operations. The notes bear interest at 10%. In March
1999, $65,000 of this amount was repaid and the rest of the principal and
accrued interest was repaid concurrent with the merger.

NOTE 5--SUBSEQUENT EVENTS:

   In July 1999, a common stock bonus was granted by a shareholder on behalf of
the Company to two employees for past services rendered in the amounts of
104,779 and 41,784 shares of the Company's common stock. The deemed value of
these shares was $10.21 per share, resulting in compensation expense of
approximately $1.5 million in July 1999. The deemed value of the Company's
stock was determined based upon the deemed value of HealthCentral.com common
stock, the per share exchange ratio and the proximity of timing in closing the
merger with HealthCentral.com.

   On August 12, 1999, the Company merged with HealthCentral.com. The purchase
price paid by HealthCentral.com was comprised of notes payable of $458,000,
cash of $51,000 and 2,357,341 shares of HealthCentral.com common stock valued
at $3.95 per share. All the Company's outstanding stock was surrendered and the
Company's shareholders received their pro rata share of the purchase price.

                         NOTES TO FINANCIAL STATEMENTS
                                  (unaudited)

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 The Company

   HealthCentralRx.com, Inc. (the "Company") was incorporated on January 27,
1999 (date of inception) as a Delaware corporation. The Company is engaged in
the development of an online drug store to provide for retail sales of
prescription pharmaceuticals, over-the-counter products and health and beauty
aids on the Internet. Since inception, the Company has been primarily involved
in securing financing, recruiting personnel and developing its website. In
September 1999, the Company began operating its online drug store.

 Development stage enterprise

   For the period from inception (January 27, 1999) through September 30, 1999,
the Company was a development stage company, as planned principal operations
had not yet generated significant revenue. In the development stage, all pre-
operating costs have been expensed as incurred.

 Use of estimates

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

 Unaudited interim financial statements

   The financial statements as of September 30, 1999 and for the period from
inception to September 30, 1999 are unaudited. Such interim financial
statements have been prepared in conformity with the rules and regulations of
the Securities and Exchange Commission. Certain disclosures normally included
in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations pertaining to interim financial statements. In the opinion of
management, all adjustments (consisting of normal recurring adjustments)
necessary for a fair presentation have been included. The results of operations
of any interim period are not necessarily indicative of the results of
operations for the full year.

 Cash and cash equivalents

   Cash and cash equivalents consist primarily of cash. The Company considers
all highly liquid investments with an original maturity of three months or less
to be cash equivalents. The Company maintains its cash in bank deposit accounts
which, at times, may exceed federally insured limits.

 Fair value

   Carrying amounts of certain of the Company's financial instruments,
including cash and cash equivalents, accounts payable and accrued expenses
approximate fair value due to their short maturities.

 Property and equipment

   Property and equipment are recorded at cost and are depreciated using the
straight-line method over estimated useful lives which range from three to five
years. Leasehold improvements and equipment held under capital leases are
amortized using the straight-line method over the term of the lease or
estimated useful lives, whichever is shorter. Repairs and maintenance costs are
charged to expense when incurred. When assets are sold or retired, the cost and
the related accumulated depreciation are removed from the accounts, and any
resulting gain or loss is included in operations.

                                  (unaudited)

 Income taxes

   The Company accounts for income taxes under the asset and liability method
which recognizes deferred tax assets and liabilities for the expected future
tax consequences of temporary differences between the tax basis of assets and
liabilities and their financial statement reported amounts. The Company records
a valuation allowance against deferred tax assets when it is more likely than
not that such assets will not be realized.

 Revenue recognition

   The Company will recognize revenues for sales of over-the-counter and health
and beauty aid products, net of discounts, when products are shipped to
customers. The Company will recognize commission revenues for the use of its
website related to sales made by its pharmacy fulfillment partner for all
prescription drugs. The Company will be responsible for all refunds relating to
sales where a customer is not satisfied with the products received. The Company
will provide an estimated allowance for such returns in the period of the sale.
The Company will also retain credit risk for sales of all products made by its
fulfillment partners.

NOTE 3--NOTE PAYABLE TO STOCKHOLDERS:

   During the period from January 27, 1999 to September 30, 1999, stockholders
of the Company advanced the Company $1,250,000 in exchange for convertible
notes payable. The notes bear interest at 4.6% and are due on the earlier of 10
days after the Company completes an initial public offering ("IPO") or one year
after the closing of the purchase of the Company by HealthCentral.com (Note 8).
Upon the completion of an IPO by HealthCentral.com, the notes are no longer
convertible.

NOTE 4--STOCK OPTION PLAN:

   In February 1999, the Company adopted the 1999 Stock Option Plan (the
"Plan"). The Plan provides for the granting of stock options to employees,
officers, directors and consultants of the Company. Options granted under the
Plan may be either incentive stock options ("ISO") or nonqualified stock
options ("NSO"). ISOs may be granted only to Company employees. NSO's may be
granted to employees and consultants. The Company has reserved 240,000 shares
of common stock for issuance under the Plan.

   Options under the Plan may be granted for periods of up to ten years and at
prices no less than 100% of the estimated fair value of the shares at the time
of grant of such option, or not less than 110% of estimated fair value for
options granted to a 10% stockholder.

   From inception through September 30, 1999, the Company granted a total of
81,098 options to employees. In September 1999, 80,098 of the options were
exercised by a cashless exercise and were remeasured to fair value in
accordance with Emerging Issues Task Force Issue No. 87-6, "Adjustments
Relating to Stock Compensation Plans" as they did not meet the minimum holding
period requirement. The expense recognized from inception to September 30, 1999
was $596,396.

   In February 1999, the Company granted 55,810 of fully vested options to non-
employees. The Company valued these options using the Black-Scholes option
pricing model applying an expected life of two years, a weighted average risk-
free rate of 4.76%, an expected dividend yield of zero percent, a volatility of
70% and a deemed value of common stock of $0.23 per share. The estimated fair
value of these options was not significant.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 The Company

   RxList.com (the "Company") was formed in 1995 as a partnership and was
incorporated in California in July 1999. The Company maintains a website that
allows visitors to search for information regarding prescription medication.
The Company's website also provides links to other prescription medication and
general medical websites.

 Use of estimates

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

 Interim financial statements (unaudited)

   The financial statements for the nine months ended September 30, 1998 are
unaudited and should be read in conjunction with the Company's annual financial
statements for the year ended December 31, 1998. The interim financial
statements have been prepared in conformity with the rules and regulations of
the Securities and Exchange Commission. Certain disclosures normally included
in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations pertaining to interim financial statements. In the opinion of
management, all adjustments (consisting of normal recurring adjustments)
necessary for a fair presentation have been included. The results of operations
of any interim period are not necessarily indicative of the results of
operations for the full year.

 Cash and cash equivalents

   The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. The Company maintains
its cash in bank deposit accounts which, at times, may exceed federally insured
limits.

 Revenue recognition

   The Company records advertising revenues in the period the advertising
impressions are delivered to customers. The Company uses an outside vendor to
solicit customers to use its advertising services, to serve the ads to its
website and to bill and collect for these services. This outside vendor
provides monthly reports indicating the impressions delivered, amounts billed
for the Company's advertising services and the related administrative fee. The
Company records advertising revenues, as reported by the outside vendor, net of
this administrative fee as the Company bears no collection risk for the gross
amount of the advertising fees. The Company's advertising contracts do not
guarantee a minimum number of impressions to be delivered.

 Production, content and product development expense

   Production, content and product development expenses consist primarily of
consulting fees and other costs related to content acquisition and licensing
and website operations.

 Concentration of credit risk

   Financial instruments that potentially subject the Company to a
concentration of credit risk consist of cash and accounts receivable. The
Company's accounts receivable are derived from revenues earned from customers
located in the U.S. The Company performs ongoing credit evaluation of its
customers' financial condition and, generally, requires no collateral from its
customers. The Company maintains an allowance for doubtful accounts receivable
based upon the expected collectibility of accounts receivable.

   The Company currently has the following concentrations of revenues and
accounts receivables:

</TABLE>

 Financial instruments

   Carrying amounts of certain of the Company's financial instruments,
including accounts receivable and accrued expenses approximate fair value due
to their short maturities.

 Equipment

   Equipment is recorded at cost and depreciated using the straight-line method
over the estimated useful life which is three years. Repairs and maintenance
costs are charged to expense when incurred. When assets are sold or retired,
the cost and the related accumulated depreciation are removed from the
accounts, and any resulting gain or loss is included in operations.

 Impairment of long-lived assets

   The Company evaluates the recoverability of long-lived assets in accordance
with Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed of". SFAS No. 121 requires recognition of impairment of long-lived
assets in the event the net book value of such assets exceeds the future
undiscounted cash flows attributable to such assets.

 Income taxes

   The Company elected to be treated as an S corporation for federal and
California income tax purposes in July 1999. As a result, minimal income taxes
were payable at the corporate level. Rather, the Company's shareholders
included their respective portions of the Company's taxable income in their
individual income tax returns. From inception through June 1999 the Company's
partners recorded their respective portions of the Company's taxable income
(loss) in their individual tax returns.

NOTE 2--RELATED PARTIES:

   During the years ended December 31, 1997, 1998 and the nine months ended
September 30, 1999, IRC Medical Publishing ("IRC") paid expenses of $3,840,
$17,088 and $27,226, respectively, on behalf of the Company. Such amounts were
not reimbursed by the Company and, accordingly, were recorded as contributed
capital in the accompanying financial statements. One of the Company's founders
is an officer of IRC.

NOTE 3--SUBSEQUENT EVENT:

   In October 1999, the Company was acquired by HealthCentral.com. The purchase
price was comprised of 836,422 shares of HealthCentral.com common stock valued
at $10.00 per share and an aggregate of $2.6 million in notes payable which
bear interest at 5% per annum. All the Company's outstanding stock was
surrendered and the Company's shareholders received their pro rata share of the
purchase price.

                               HEALTHCENTRAL.COM

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

   On August 12, 1999 and October 5, 1999, HealthCentral.com acquired Windom
Health Enterprises, Inc. ("Windom Health") and HealthCentralRx.com, Inc.,
respectively, in transactions accounted for using the purchase method of
accounting. On October 28, 1999, HealthCentral.com acquired RxList.com, which
will also be accounted for using the purchase method of accounting. Under the
purchase method of accounting, the aggregate purchase price is allocated to the
tangible and identifiable intangible assets acquired and liabilities assumed on
the basis of their fair values on the acquisition date. The unaudited pro forma
combined balance sheet is based on the consolidated balance sheet of the
Company at September 30, 1999 and the balance sheets of HealthCentralRx.com and
RxList.com at September 30, 1999 assuming the transactions were consummated on
September 30, 1999. The unaudited pro forma combined statements of operations
are based on the individual statements of operations of the Company for the
year ended December 31, 1998 and the nine months ended September 30, 1999. The
operations of Windom Health and RxList.com have been included in the unaudited
pro forma combined statements of operations as though these acquisitions had
been consummated on January 1, 1998. The operations of HealthCentralRx.com have
been included in the unaudited pro forma combined statement of operations from
its inception (January 27, 1999).

   The pro forma information has been prepared in accordance with the rules and
regulations of the Securities and Exchange Commission and is provided for
illustrative purposes only. The pro forma information does not purport to be
indicative of the results that actually would have occurred had the
combinations been effected on the dates indicated above. The unaudited pro
forma financial statements, including the notes thereto, are qualified in their
entirety by reference to, and should be read in conjunction with Management's
Discussion and Analysis of Financial Condition and Results of Operations and
the consolidated financial statements and notes thereto, which are included
elsewhere herein.

   The total purchase price of $12.7 million consisted of cash of $51,000, a
note payable of $458,000, 2,104,770 shares of the Company's common stock valued
at $9,311,514, assumed liabilities of $2,868,457 and estimated transaction
costs of $65,000. The deemed value of the Company's common stock on the date
the definitive merger agreement was signed was $4.42 per share.

   The valuation of the purchased in-process research development of $555,000
was based on the result of an independent appraisal using the income approach.
The income approach estimates the value of the asset based on its expected
economic benefit. The valuation analysis considered the contribution of the
core technology as well as the percent complete of the in-process research and
development. The expected cash flows associated with the in-process research
and development were discounted to the present value using a rate of return
that is commensurate with the risk of the asset. The purchased in-process
technology was not considered to have reached technological feasibility and had
no alternatives future use.

   Goodwill and other intangibles are being amortized on a straightline basis
over the estimated period of benefit of two to three years.

   The total purchase price of $11.0 million consisted of 836,422 shares of the
Company's common stock valued at $8,364,216, an aggregate of $2.6 million in
notes payable issued to RxList.com shareholders discounted at a deemed interest
rate of 10% over 6 months and estimated transaction costs of $143,000. The
deemed value of the Company's common stock on the date the acquisition
agreement was signed was $10.00.

   Goodwill and other intangibles are being amortized on a straightline basis

   The unaudited pro forma condensed statements of operations exclude the
effect of the charges for in-process research and development. These amounts
are reflected as charges to the accumulated deficit in the unaudited pro forma
balance sheet.

   There were no material differences in the accounting policies of the

NOTE 2--UNAUDITED PRO FORMA COMBINED NET LOSS PER SHARE:

   The net loss per share and shares used in computing the net loss per share
for the year ended December 31, 1998 and the nine months ended September 30,
1999 are based upon the historical weighted average common shares outstanding.
Common stock issuable upon the exercise of the stock options and warrants has
been excluded from the computation of net loss per share as their effect would
be anti-dilutive. In addition to the shares used in computing the net loss per
share above, pro forma net loss per share is calculated as if the outstanding
shares of convertible preferred stock were converted to common stock at the
time of issuance.

   The 5,076,464 shares of common stock issued in connection with the
acquisitions have been included in the calculation of pro forma basic and
diluted net loss per share as follows:

award, or a corporation's board of directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended. Article XII of

Bylaws (Exhibit 3.5 hereto) provide for indemnification of HealthCentral.com's
directors, officers, employees and other agents to the maximum extent
permitted by Delaware Law. In addition, HealthCentral.com has entered into
Indemnification Agreements (Exhibit 10.24 hereto) with certain officers and

       every outstanding share of common stock will be split into 1.25 shares
       of common stock.

   (b) There were no underwritten offerings employed in connection with any of
the transactions set forth in Item 15(a).

   All of the foregoing information gives effect to the five-for-four split of
the Registrant's common stock to be effected prior to completion of the
offering. The issuances described in Items 15(a)(1) through 15(a)(11) as well
as the issuances in 15(a)(13) were deemed to be exempt from registration under
the Securities Act in reliance upon Section 4(2) thereof as transactions by an
issuer not involving any public offering. The issuances described in Items
15(a)(12) were deemed exempt from the registration under the Securities Act in
reliance upon Rule 701 promulgated thereunder in that they were offered and
sold either pursuant to written compensatory benefit plans or pursuant to a
written contract relating to compensation, as provided by Rule 701. In
addition, such issuances were deemed to be exempt from registration under
Section 4(2) of the Securities Act as transactions by an issuer not involving
any public offering. The issuances described in Items 15(a)(14) and (15) were
or will be exempt from registration under Section 2(3) of the Securities Act
on the basis that such transaction did not involve a "sale" of securities. The
recipients of securities in each such transaction represented their intentions
to acquire the securities for investment only and not with a view to or for
sale in connection with any distribution thereof and appropriate legends were
affixed to the securities issued in such transactions. All recipients had
adequate access, through their relationships with the Company, to information

Item 17. Undertakings

   The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

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

   The undersigned registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this registration statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

          (a) General.  The Plan shall be administered by the Board or a
              -------
Committee, or a combination thereof, as determined by the Board.  The Plan may
be administered by different administrative bodies with respect to different
classes of Participants and, if permitted by the Applicable Laws, the Board may
authorize one or more officers to grant Options or Stock Purchase Rights to
Employees and Consultants.

          (b) Administration with respect to Reporting Persons.  With respect to
              ------------------------------------------------
Options granted to Reporting Persons and Named Executives, the Plan may (but
need not) be administered so as to permit such Options to qualify for the
exemption set forth in Rule 16b-3(d) and to qualify as performance-based
compensation under Section 162(m) of the Code.

          (c) Committee Composition.  If a Committee has been appointed pursuant
              ---------------------
to this Section 4, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board.  From time to time the Board may
increase the size of any Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies (however caused) and remove all members of a Committee
and thereafter directly administer the Plan, all to the extent permitted by the
Applicable Laws and, in the case of a Committee administering the Plan pursuant
to Section 4(b) above, to the extent permitted or required by Rule 16b-3 and
Section 162(m) of the Code.

          (d) Powers of the Administrator.  Subject to the provisions of the
              ---------------------------
Plan and in the case of a Committee, the specific duties delegated by the Board
to such Committee, the Administrator shall have the authority, in its
discretion:

              (i)       to determine the Fair Market Value of the Common Stock,
in accordance with Section 2(p) of the Plan;

              (ii)      to select the Employees and Consultants to whom Options
and Stock Purchase Rights or any combination thereof may from time to time be
granted;

              (iii)     to determine whether and to what extent Options and
Stock Purchase Rights or any combination thereof are granted;

              (iv)      to determine the number of Shares of Common Stock to be
covered by each such award granted;

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

              (vi)      to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any award granted hereunder, which terms and
conditions include but are

                                      -5-
<PAGE>

not limited to the exercise or purchase price, the time or times when Options or
Stock Purchase Rights may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option, Optioned Stock, Stock
Purchase Right or Restricted Stock, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

              (vii)     to determine whether and under what circumstances an
Option may be settled in cash under Section 10(f) instead of Common Stock;

              (viii)    to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option shall have declined since the date the Option was granted and to
make any other amendments or adjustments to any Option that the Administrator
determines, in its discretion and under the authority granted to it under the
Plan, to be necessary or advisable, provided however that no amendment or
adjustment to an Option that would materially and adversely affect the rights of
any Optionee shall be made without the prior written consent of the Optionee;

              (ix)      to determine the terms and restrictions applicable to
Stock Purchase Rights and the Restricted Stock purchased by exercising such
Stock Purchase Rights;

              (x)       to initiate an Option Exchange Program;

              (xi)      to construe and interpret the terms of the Plan and
awards granted under the Plan; and

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

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

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

          (a) Recipients of Grants.  Nonstatutory Stock Options and Stock
              --------------------
Purchase Rights may be granted to Employees and Consultants.  Incentive Stock
Options may be granted only to Employees, provided however that Employees of
Affiliates shall not be eligible to receive Incentive Stock Options.  An
Employee or Consultant who has been granted an Option or Stock Purchase Right
may, if he or she is otherwise eligible, be granted additional Options or Stock
Purchase Rights.

          (b) Type of Option.  Each Option shall be designated in Option
              --------------
Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.  For

                                      -6-
<PAGE>

purposes of this Section 5(b), Incentive Stock Options shall be taken into
account in the order in which they were granted, and the Fair Market Value of
the Shares subject to an Incentive Stock Option shall be determined as of the
date of the grant of such Option.

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

     6.  Term of Plan.  The Plan shall become effective upon its adoption by the
         ------------
Board.  It shall continue in effect for a term of ten (10) years unless sooner
terminated under Section 16 of the Plan.

     7.  Term of Option.  The term of each Option shall be the term stated in
         --------------
the Option Agreement; provided however that the term shall be no more than ten
(10) years from the date of grant thereof or such shorter term as may be
provided in the Option Agreement and provided further that, in the case of an
Incentive Stock Option granted to a person who at the time of such grant is a
Ten Percent Holder, the term of the Option shall be five (5) years from the date
of grant thereof or such shorter term as may be provided in the Option
Agreement.

     8.  Limitation on Grants to Employees.  Subject to adjustment as provided
         ---------------------------------
in Section 14 below, the maximum number of Shares which may be subject to
Options and Stock Purchase Rights granted to any one Employee under this Plan
for any fiscal year of the Company shall be 2,000,000 (after giving effect to
the Company's 5-for-4 stock split effected in connection with its
reincorporation under the laws of Delaware and subject to further adjustment
pursuant to Section 14 below).

     9.  Option Exercise Price and Consideration.
         ---------------------------------------

          (a) Exercise Price.  The per Share exercise price for the Shares to be
              --------------
issued pursuant to exercise of an Option shall be such price as is determined by
the Administrator and set forth in the Option Agreement, but shall be subject to
the following:

              (i)       In the case of an Incentive Stock Option

                        (A) granted to an Employee who at the time of grant is a
Ten Percent Holder, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant; or

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

              (ii)      In the case of a Nonstatutory Stock Option, the per
Share exercise price shall be such price as is determined by the Administrator;
provided however that in the case of a Nonstatutory Stock option granted to a
person who, at the time of the grant of such Option, is a Named Executive of the
Company, the per Share Exercise Price shall be no less than 100% of the Fair
Market Value on the date of grant if such Option is intended to qualify as

                                      -7-
<PAGE>

performance-based compensation under Section 162(m) of the Code and if not so
intended shall be such price as is determined by the Administrator.

              (iii)     Notwithstanding the foregoing, Options may be granted
with a per Share exercise price other than as required above pursuant to a
merger or other corporate transaction.

          (b) Permissible Consideration.  The consideration to be paid for the
              -------------------------
Shares to be issued upon exercise of an Option, including the method of payment,
shall be determined by the Administrator (and, in the case of an Incentive Stock
Option, shall be determined at the time of grant) and may consist entirely of
(1) cash; (2) check; (3) delivery of Optionee's promissory note with such
recourse, interest, security and redemption provisions as the Administrator
determines to be appropriate (subject, if applicable, to the provisions of
Section 153 of the Delaware General Corporation Law); (4) cancellation of
indebtedness; (5) other Shares that (x) in the case of Shares acquired upon
exercise of an Option either have been owned by the Optionee for more than six
months on the date of surrender (or such other period as may be required to
avoid a charge to the Company's earnings) or were not acquired, directly or
indirectly, from the Company, and (y) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which the
Option is exercised; (6) authorization from the Company to retain from the total
number of Shares as to which the Option is exercised that number of Shares
having a Fair Market Value on the date of exercise equal to the exercise price
for the total number of Shares as to which the Option is exercised; (7) delivery
of a properly executed exercise notice together with such other documentation as
the Administrator and the broker, if applicable, shall require to effect
exercise of the Option and prompt delivery to the Company of the sale or loan
proceeds required to pay the exercise price and any applicable withholding
taxes; (8) any combination of the foregoing methods of payment; or (9) such
other consideration and method of payment for the issuance of Shares to the
extent permitted under the Applicable Laws.  In making its determination as to
the type of consideration to accept, the Administrator shall consider if
acceptance of such consideration may be reasonably expected to benefit the
Company and the Administrator may refuse to accept a particular form of
consideration at the time of any Option exercise if, in its sole discretion,
acceptance of such form of consideration is not in the best interests of the
Company at such time.

     10.  Exercise of Option.
          ------------------

          (a) Procedure for Exercise; Rights as a Stockholder. Any Option
              -----------------------------------------------
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, consistent with the terms of the Plan, and
reflected in the Option Agreement, including vesting requirements and/or
performance criteria with respect to the Company and/or the Optionee.  The
Administrator shall have the discretion to determine whether and to what extent
the vesting of Options shall be tolled during any unpaid leave of absence.

              An Option may not be exercised for a fraction of a Share.

              An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and the Company has
received full payment for the Shares with

                                      -8-
<PAGE>

respect to which the Option is exercised. Full payment may, as authorized by the
Administrator, consist of any consideration and method of payment allowable
under Section 9(b) of the Plan. Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Optioned Stock, not withstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such stock certificate promptly
upon exercise of the Option. No adjustment will be made for a dividend or other
right for which the record date is prior to the date the stock certificate is
issued, except as provided in Section 14 of the Plan.

              Exercise of an Option in any manner shall result in a decrease in
the number of Shares that thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b) Termination of Employment or Consulting Relationship.  In the
              ----------------------------------------------------
event of termination of an Optionee's Continuous Service Status, such Optionee
may, but only within three (3) months (or such other period of time as is
determined by the Administrator, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option) after the
date of such termination (but in no event later than the expiration date of the
term of such Option as set forth in the Option Agreement), exercise his or her
Option to the extent that the Optionee was entitled to exercise it at the date
of such termination.  To the extent that the Optionee was not entitled to
exercise the Option at the date of such termination, or if the Optionee does not
exercise such Option to the extent so entitled within the time specified herein,
the Option shall terminate.  Unless otherwise determined by the Administrator or
the Company, no termination shall be deemed to occur and this Section 10(b)
shall not apply if (i) the Optionee is a Consultant who becomes an Employee; or
(ii) the Optionee is an Employee who becomes a Consultant.

          (c) Disability of Optionee.   Notwithstanding Section 10(b) above,
              ----------------------

              (i)       In the event of termination of an Optionee's Continuous
Service Status as a result of his or her total and permanent disability (within
the meaning of Section 22(e)(3) of the Code), Optionee may, but only within
twelve (12) months (or such other period of time as is determined by the
Administrator, with such determination in the case of an Incentive Stock Option
made at the time of grant of the Option) from the date of such termination (but
in no event later than the expiration date of the term of such Option as set
forth in the Option Agreement), exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination. To the extent that
Optionee was not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate.

              (ii)      In the event of termination of an Optionee's Continuous
Service Status as a result of a disability which does not fall within the
meaning of total and permanent disability (as set forth in Section 22(e)(3) of
the Code), Optionee may, but only within six (6) months (or such other period of
time as is determined by the Administrator, with such determination in the case
of an Incentive Stock Option made at the time of grant of the Option) from the
date of such termination (but in no event later than the expiration date of the
term of

                                      -9-
<PAGE>

such Option as set forth in the Option Agreement), exercise the Option to the
extent otherwise entitled to exercise it at the date of such termination.
However, to the extent that such Optionee fails to exercise an Option which is
an Incentive Stock Option within three (3) months of the date of such
termination, the Option will not qualify for Incentive Stock Option treatment
under the Code. To the extent that Optionee was not entitled to exercise the
Option at the date of termination, or if Optionee does not exercise such Option
to the extent so entitled within six months (6) from the date of termination,
the Option shall terminate.

          (d) Death of Optionee.  Notwithstanding Section 10(b) above, in the
              -----------------
event of the death of an Optionee during the period of Continuous Service Status
since the date of grant of the Option, or within thirty (30) days following
termination of Optionee's Continuous Service Status, the Option may be
exercised, at any time within twelve (12) months (or such other period of time
as is determined by the Administrator, with such determination in the case of an
Incentive Stock Option made at the time of grant of the Option) following the
date of death (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), by Optionee's estate or by a
person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent of the right to exercise that had accrued at the date of
death or, if earlier, the date of termination of Optionee's Continuous Service
Status.  To the extent that Optionee was not entitled to exercise the Option at
the date of death or termination, as the case may be, or if Optionee does not
exercise such Option to the extent so entitled within the time specified herein,
the Option shall terminate.

          (e) Extension of Exercise Period.  The Administrator shall have full
              ----------------------------
power and authority to extend the period of time for which an Option is to
remain exercisable following termination of an Optionee's Continuous Service
Status from the periods set forth in Sections 10(b), 10(c) and 10(d) above or in
the Option Agreement to such greater time as the Administrator shall deem
appropriate, provided that in no event shall such Option be exercisable later
than the date of expiration of the term of such Option as set forth in the
Option Agreement.

          (f) Buyout Provisions.  The Administrator may at any time offer to buy
              -----------------
out for a payment in cash or Shares an Option previously granted under the Plan
based on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

     11.  Stock Purchase Rights.
          ---------------------

          (a) Rights to Purchase.  Stock Purchase Rights may be issued either
              ------------------
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan.  After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing of the terms, conditions and restrictions related to the
offer, including the number of Shares that such person shall be entitled to
purchase, the price to be paid, and the time within which such person must
accept such offer.  The purchase price of Shares subject to Stock Purchase
Rights shall be as determined by the Administrator in accordance with the
Applicable Laws.  The offer to purchase Shares subject to Stock Purchase Rights
shall be accepted by execution of a Restricted Stock Purchase Agreement in the
form determined by the Administrator.

                                      -10-
<PAGE>

          (b) Repurchase Option.  Unless the Administrator determines otherwise,
              -----------------
the Restricted Stock Purchase Agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's employment or consulting relationship with the Company for any
reason (including death or disability).  The purchase price for Shares
repurchased pursuant to the Restricted Stock Purchase Agreement shall be the
original purchase price paid by the purchaser and may be paid by cash or
cancellation of any indebtedness of the purchaser to the Company. The repurchase
option shall lapse at such rate as the Administrator may determine in accordance
with the Applicable Laws.

          (c) Other Provisions.  The Restricted Stock Purchase Agreement shall
              ----------------
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.  In
addition, the provisions of Restricted Stock Purchase Agreements need not be the
same with respect to each purchaser.

          (d) Rights as a Stockholder.  Once the Stock Purchase Right is
              -----------------------
exercised, the purchaser shall have the rights equivalent to those of a
stockholder, and shall be a stockholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company.  No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 14
of the Plan.

     12.  Taxes.
          -----

          (a) As a condition of the exercise of an Option or Stock Purchase
Right granted under the Plan, the Participant (or in the case of the
Participant's death, the person exercising the Option or Stock Purchase Right)
shall make such arrangements as the Administrator may require for the
satisfaction of any applicable federal, state, local or foreign withholding tax
obligations that may arise in connection with the exercise of Option or Stock
Purchase Right and the issuance of Shares.  The Company shall not be required to
issue any Shares under the Plan until such obligations are satisfied.

          (b) In the case of an Employee and in the absence of any other
arrangement, the Employee shall be deemed to have directed the Company to
withhold or collect from his or her compensation an amount sufficient to satisfy
such tax obligations from the next payroll payment otherwise payable after the
date of an exercise of the Option or Stock Purchase Right.

          (c) This Section 12(c) shall apply only after the date, if any, upon
which the Common Stock becomes a Listed Security.  In the case of Participant
other than an Employee (or in the case of an Employee where the next payroll
payment is not sufficient to satisfy such tax obligations, with respect to any
remaining tax obligations), in the absence of any other arrangement and to the
extent permitted under the Applicable Laws, the Participant shall be deemed to
have elected to have the Company withhold from the Shares to be issued upon
exercise of the Option or Stock Purchase Right that number of Shares having a
Fair Market Value determined as of the applicable Tax Date (as defined below)
equal to the amount required to be withheld.  For purposes of this Section 12,
the Fair Market Value of the Shares to be withheld shall be determined on the
date that the amount of tax to be withheld is to be determined under the
Applicable Laws (the "Tax Date").

                                      -11-
<PAGE>

          (d) If permitted by the Administrator, in its discretion, a
Participant may satisfy his or her tax withholding obligations upon exercise of
an Option or Stock Purchase Right by surrendering to the Company Shares that (i)
in the case of Shares previously acquired from the Company, have been owned by
the Participant for more than six (6) months on the date of surrender, and (ii)
have a Fair Market Value determined as of the applicable Tax Date equal to the
amount required to be withheld.

          (e) Any election or deemed election by a Participant to have Shares
withheld to satisfy tax withholding obligations under Section 12(c) or (d) above
shall be irrevocable as to the particular Shares as to which the election is
made and shall be subject to the consent or disapproval of the Administrator.
Any election by a Participant under Section 12(d) above must be made on or prior
to the applicable Tax Date.

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

     13.  Non-Transferability of Options and Stock Purchase Rights.  Options and
          --------------------------------------------------------
Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred or disposed of in any manner other than by will or by the laws of
descent or distribution; provided that the Administrator may in its discretion
and to the extent permitted by the Applicable Laws grant transferable
Nonstatutory Stock Options pursuant to Option Agreements specifying (i) the
manner in which such Nonstatutory Stock Options are transferable and (ii) that
any such transfer shall be subject to the Applicable Laws.  The designation of a
beneficiary by an Optionee will not constitute a transfer.  An Option or Stock
Purchase Right may be exercised, during the lifetime of the holder of Option or
Stock Purchase Right, only by such holder or a transferee permitted by this
Section 13.

     14.  Adjustments Upon Changes in Capitalization, Merger or Certain Other
          -------------------------------------------------------------------
Transactions.
------------

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------
stockholders of the Company, the number of Shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, the number of Shares set forth
in Sections 3(a)(i) and 8 above, and the number of Shares of Common Stock that
have been authorized for issuance under the Plan but as to which no Options or
Stock Purchase Rights have yet been granted or that have been returned to the
Plan upon cancellation or expiration of an Option or Stock Purchase Right, as
well as the price per Share of Common Stock covered by each such outstanding
Option or Stock Purchase Right, shall be proportionately adjusted for any
increase or decrease in the number of issued Shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination,
recapitalization or reclassification of the Common Stock, or any other increase
or decrease in the number of issued Shares of Common Stock effected without
receipt of consideration by the Company; provided however that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such

                                      -12-
<PAGE>

adjustment shall be made by the Administrator, whose determination in that
respect shall be final, binding and conclusive. Except as expressly provided
herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of Shares of Common Stock subject to an Option or Stock Purchase Right.

          (b) Dissolution or Liquidation.  In the event of the proposed
              --------------------------
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action.  To the extent it has
not been previously exercised, the Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

          (c) Corporate Transaction; Change in Control.  In the event of a
              ----------------------------------------
Corporate Transaction or a Change in Control, each outstanding Option and Stock
Purchase Right shall be assumed or an equivalent option or right shall be
substituted by the successor corporation or a Parent or Subsidiary of such
successor corporation (such entity, the "Successor Corporation"), unless the
                                         ---------------------
Successor Corporation does not agree to assume the outstanding Options or Stock
Purchase Rights or to substitute equivalent options or rights, in which case
such Options or Stock Purchase Rights shall terminate upon the consummation of
the transaction.  In the event of a transaction that qualifies as a Change of
Control (i) in which outstanding awards are being assumed or substituted, the
vesting and exercisability of each outstanding Option and Stock Purchase Right
shall accelerate such that the Options and Stock Purchase Rights shall become
vested and exercisable to the extent of 50% of the Shares then unvested, and any
repurchase right of the Company with respect to Shares issued upon exercise of
an Option or Stock Purchase Right shall lapse as to 50% of the Shares subject to
such repurchase right prior to consummation of the Change of Control, and (ii)
in which outstanding awards are terminating because the Successor Corporation
has not agreed to assume or substitute such awards, the vesting and
exercisability of each outstanding Option and Stock Purchase Right shall
accelerate such that the Options and Stock Purchase Rights shall become vested
and exercisable to the extent of 100% of the Shares then unvested, and any
repurchase right of the Company with respect to Shares issued upon exercise of
an Option or Stock Purchase Right shall lapse as to 100% of the Shares subject
to such repurchase right prior to consummation of the Change of Control, in each
case at such time and upon such conditions as the Administrator shall determine.
To the extent that an Option or Stock Purchase Right is not exercised prior to
consummation of a Corporate Transaction or Change of Control in which the Option
or Stock Purchase Right is not being assumed or substituted, such Option or
Stock Purchase Right shall terminate upon such consummation and the
Administrator shall notify the Optionee or holder of such fact at least five (5)
days prior to the date on which the Option or Stock Purchase Right terminates.

          For purposes of this Section 14, an Option shall be considered
assumed, without limitation, if, at the time of issuance of the stock or other
consideration upon a Corporate Transaction or Change of Control, as the case may
be, each holder of an Option would be entitled to receive upon exercise of the
Option the same number and kind of shares of stock or the same amount of
property, cash or securities as such holder would have been entitled to receive
upon the occurrence of the transaction if the holder had been, immediately prior
to such transaction, the holder of the number of Shares of Common Stock covered
by the Option at such time (after giving effect to any adjustments in the number
of Shares covered by the Option as provided for in this Section 14); provided,
however, that if such consideration received in the transaction was not solely
common stock of the Successor Corporation, the Administrator may, with the
consent of the Successor Corporation, provide for the consideration to be
received upon exercise of the

                                      -13-
<PAGE>

Option to be solely Common Stock of the Successor Corporation equal to the Fair
Market Value of the per Share consideration received by holders of Common Stock
in the transaction.

          (d) Certain Distributions.  In the event of any distribution to the
              ---------------------
Company's stockholders of securities of any other entity or other assets (other
than dividends payable in cash or stock of the Company) without receipt of
consideration by the Company, the Administrator may, in its discretion,
appropriately adjust the price per Share of Common Stock covered by each
outstanding Option or Stock Purchase Right to reflect the effect of such
distribution.

          (e) Limitation on Payments.  In the event that the vesting
              ----------------------
acceleration provided for in subsection (c) above (x) constitutes "parachute
payments" within the meaning of Section 280G of the Internal Revenue Code (the

"Code"), and (y) but for this Section 14(e) would be subject to the excise tax
-----
imposed by Section 4999 of the Code (or any corresponding provisions of state
income tax law), then such vesting acceleration shall be either

                 (A)  delivered in full, or

                 (B)  delivered as to such lesser extent which would result in
no portion of such severance benefits being subject to excise tax under Code
Section 4999,

whichever of the foregoing amounts, taking into account the applicable federal,
state and local income taxes and the excise tax imposed by Code Section 4999,
results in the receipt by the optionee on an after-tax basis of the greater
amount of acceleration benefits, notwithstanding that all or some portion of
such benefits may be taxable under Code Section 4999. Any determination required
under this Section 14(e) shall be made in writing by the Company's independent
accountants or other outside tax advisors, whose determination shall be based on
factual assertions provided by the Company, and which will be conclusive and
binding for all purposes on the Company and the optionee. In the event that (A)
above applies, then the optionee shall be responsible for any excise taxes
imposed with respect to such benefits. In the event that (B) above applies, then
each benefit provided hereunder shall be proportionately reduced to the extent
necessary to avoid imposition of such excise taxes.

     15.  Time of Granting Options and Stock Purchase Rights.  The date of grant
          --------------------------------------------------
of an Option or Stock Purchase Right shall, for all purposes, be the date on
which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Administrator;
provided however that in the case of any Incentive Stock Option, the grant date
shall be the later of the date on which the Administrator makes the
determination granting such Incentive Stock Option or the date of commencement
of the Optionee's employment relationship with the Company.  Notice of the
determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

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

          (a) Authority to Amend or Terminate.  The Board may at any time amend,
              -------------------------------
alter, suspend or discontinue the Plan, but no amendment, alteration, suspension
or discontinuation (other than an adjustment pursuant to Section 14 above) shall
be made that would materially and adversely affect the rights of any
Participant, without his or her consent.  In addition, to the extent necessary
and desirable to comply with the Applicable Laws, the Company shall obtain
stockholder approval of any Plan amendment in such a manner and to such a degree
as required.

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

     17.  Conditions Upon Issuance of Shares.  Notwithstanding any other
          ----------------------------------
provision of the Plan or any agreement entered into by the Company pursuant to
the Plan, the Company shall not be obligated, and shall have no liability for
failure, to issue or deliver any Shares under the Plan unless such issuance or
delivery would comply with the Applicable Laws, with such compliance determined
by the Company in consultation with its legal counsel.  As a condition to the
exercise of an Option or Stock Purchase Right, the Company may require the
person exercising such Option or Stock Purchase Right to represent and warrant
at the time of any such exercise that the Shares are being purchased only for
investment and without any present intention to sell or distribute such Shares
if, in the opinion of counsel for the Company, such a representation is required
by law.

                                      -14-
<PAGE>

     18.  Reservation of Shares.  The Company, during the term of this Plan,
          ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     19.  Agreements.  Options and Stock Purchase Rights shall be evidenced by
          ----------
Option Agreements and Restricted Stock Purchase Agreements, respectively, in
such form(s) as the Administrator shall from time to time approve.

     20.  Stockholder Approval.  If required by the Applicable Laws, continuance
          --------------------
of the Plan shall be subject to approval by the stockholders of the Company
within twelve (12) months before or after the date the Plan is adopted.  Such
stockholder approval shall be obtained in the manner and to the degree required
under the Applicable Laws.

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

      1.  Grant of Option.
          ---------------

          (a) General Terms.  HealthCentral.com (the "Company"), hereby grants
              -------------                           -------
to the Optionee named in the Notice of Stock Option Grant attached to this
Agreement ("Optionee"), an option (the "Option") to purchase the total number of
            --------                    ------
shares of Common Stock (the "Shares") set forth in the Notice of Stock Option
                             ------
Grant, at the exercise price per share set forth in the Notice of Stock Option
Grant (the "Exercise Price") subject to the terms, definitions and provisions of
            --------------
the 1999 Stock Plan (the "Plan") adopted by the Company, which is incorporated
                          ----
in this Agreement by reference.  In the event of a conflict between the terms of
the Plan and the terms of this Agreement, the terms of the Plan shall govern.
Unless otherwise defined in this Agreement, the terms used in this Agreement
shall have the meanings defined in the Plan.

          (b) Tax Status of Option.  Unless and to the extent designated a
              --------------------
Nonstatutory Stock Option in the Notice of Stock Option Grant, this Option is
intended to be an Incentive Stock Option as defined in Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), to the maximum extent
                                                ----
permitted under applicable tax law.  If any portion of this Option is designated
as an Incentive Stock Option it shall qualify as such only to the extent that
the aggregate fair market value of the Shares (generally, the Option's exercise
price) subject to this Option (and all other Incentive Stock Options granted to
Optionee by the Company or any Parent or Subsidiary) that first become
exercisable in any calendar year does not exceed $100,000.  To the extent that
the aggregate fair market value of such Shares exceeds $100,000, the Shares in
excess of such limit shall be treated as subject to a Nonstatutory Stock Option,
in accordance with Section 5 of the Plan.

      2.  Exercise of Option.  This Option shall be exercisable during its term
          ------------------
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Sections 9 and 10 of the Plan as follows:

          (a)  Right to Exercise.
               -----------------

               (i) This Option may not be exercised for a fraction of a share.

              (ii) In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by this
Section 2 and by Sections 6, 7 and 8 below.

             (iii) In no event may this Option be exercised after the Expiration
Date of the Option as set forth in the Notice of Stock Option Grant.

          (b)  Method of Exercise.
               ------------------

              (i) This Option shall be exercisable by delivering to the Company
a written notice of exercise (in the form attached as Exhibit A) which shall
                                                      ---------
state the election to exercise the Option, the number of Shares in respect of
which the Option is being exercised, and such other representations and
agreements as to the holder's investment intent with respect to such Shares of
Common Stock as may be required by the Company pursuant to the provisions of the
Plan. Such written notice shall be signed by Optionee and shall be delivered in
person or by certified mail to the Secretary of the Company. The written notice
shall be accompanied by payment of the Exercise Price. This Option

                                      -1-
<PAGE>

shall be deemed to be exercised upon receipt by the Company of such written
notice accompanied by the Exercise Price.

           (ii) As a condition to the exercise of this Option, Optionee agrees
to make adequate provision for federal, state or other tax withholding
obligations, if any, which arise upon the exercise of the Option or disposition
of Shares, whether by withholding, direct payment to the Company, or otherwise.

          (iii) No Shares will be issued pursuant to the exercise of an Option
unless such issuance and such exercise shall comply with all relevant provisions
of law and the requirements of any stock exchange upon which the Shares may then
be listed.  Assuming such compliance, for income tax purposes the Shares shall
be considered transferred to Optionee on the date on which the Option is
exercised with respect to such Shares.

     3.  Optionee's Representations.  In the event the Shares purchasable
         --------------------------
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), at the time this
                                         --------------
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.

     4.  Method of Payment.  Payment of the Exercise Price shall be by any of
         -----------------
the following, or a combination of the following, at the election of Optionee:
(a) cash; (b) check; (c) surrender of other Shares of Common Stock of the
Company that (i) either have been owned by Optionee for more than six (6) months
on the date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which the Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.

     5.  Restrictions on Exercise.  This Option may not be exercised until such
         ------------------------
time as the Plan has been approved by the stockholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("Regulation G") as
                                                          ------------
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     6.  Termination of Relationship.  In the event of termination of Optionee's
         ---------------------------
Continuous Service Status, Optionee may, to the extent otherwise so entitled at
the date of such termination (the "Termination Date"), exercise this Option
                                   ----------------
during the Termination Period set out in the Notice of Stock Option Grant.  To
the extent that Optionee was not entitled to exercise this Option at the date of
such termination, or if Optionee does not exercise this Option within the time
specified in the Notice of Stock Option Grant, the Option shall terminate.

     7.  Disability of Optionee.  Notwithstanding the provisions of Section 6
         ----------------------
above, in the event of termination of Optionee's Continuous Service Status as a
result of total and permanent disability (as

                                      -2-
<PAGE>

defined in Section 22(e)(3) of the Code), Optionee may, but only within twelve
(12) months from the date of termination of employment (but in no event later
than the Expiration Date of the Option as set forth in the Notice of Stock
Option Grant), exercise the Option to the extent otherwise so entitled at the
date of such termination. To the extent that Optionee was not entitled to
exercise the Option at the date of termination, or if Optionee does not exercise
such Option (to the extent otherwise so entitled) within the time specified in
this Agreement, the Option shall terminate.

     8.  Death of Optionee.  In the event of the death of Optionee (a) during
         -----------------
the term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Service Status since the date of grant of the Option,
or (b) within thirty (30) days after the termination of Optionee's Continuous
Service Status, the Option may be exercised, at any time within twelve (12)
months following the date of death (but in no event later than the Expiration
Date of the Option as set forth in the Notice of Stock Option Grant), by
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of death or termination, as applicable.  To the extent
that Optionee was not entitled to exercise this Option at the date of death or
termination, as applicable, or if Optionee's estate or the person who acquired
the right to exercise the Option as a result of Optionee's death does not
exercise this Option within the time specified in the Notice of Stock Option
Grant, the Option shall terminate

     9.  Non-Transferability of Option.  Except as otherwise provided in this
         -----------------------------
Section 9, this Option may not be transferred in any manner otherwise than by
will or by the laws of descent or distribution and may be exercised during the
lifetime of Optionee only by him or her.  However, Optionee, with the approval
of the Administrator, may transfer the Option to or for the benefit of one or
more members of Optionee's Immediate Family (as defined below), including,
without limitation, to a trust for the benefit of one or more members of
Optionee's Immediate Family or to a partnership or limited liability company
composed of one or more members of Optionee's Immediate Family, and subject to
such limits as the Administrator may establish.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and permitted
transferees of Optionee.  No transfer for consideration shall be permitted
except to a partnership or limited liability company composed of one or more
members of Optionee's Immediate Family.

     The foregoing right to transfer the Option shall apply to the right to
consent to amendments to this Agreement and, in the discretion of the
Administrator, shall also apply to the right to transfer ancillary rights
associated with the Option.  The term "Immediate Family" shall mean Optionee's
spouse or former spouse, parents, children, stepchildren, adoptive
relationships, sisters, brothers, grandchildren, nieces, nephews, mother-in-law,
father-in-law, sons-in-law, daughters-in-law, brothers-in-law or sisters-in-law
(and, for this purpose, shall also include Optionee). Optionee acknowledges and
agrees that Optionee shall be responsible for payment of any applicable income
and employment tax withholdings imposed upon the transfer and/or subsequent
exercise of a transferred Option, and such transfer and the transferee's right
to receive the shares subject to this Option upon exercise thereof is
conditioned on satisfaction of such withholding taxes as the Company determines
may be due.

     10.  Term of Option.  This Option may be exercised only within the term set
          --------------
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the Plan and the terms of this Option.

     11.  No Additional Employment Rights.  Optionee understands and agrees that
          -------------------------------
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an Employee or Consultant at the will of the Company (not through
the act of being hired, being granted this Option or acquiring Shares under this
Agreement).  Optionee further acknowledges and agrees that nothing in this
Agreement

                                      -3-
<PAGE>

or the Plan shall confer upon Optionee any right with respect to continuation as
an Employee or Consultant with the Company, nor shall it interfere in any way
with his or her right or the Company's right to terminate his or her employment
or consulting relationship at any time, with or without cause.

     12.  Tax Consequences.  Optionee acknowledges that he or she has read the
          ----------------
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE AND
DOES NOT ADDRESS STATE, LOCAL OR FOREIGN ISSUES, AND THAT THE TAX LAWS AND
REGULATIONS SUMMARIZED ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS OR
HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a) Exercise of Incentive Stock Option.  If this Option is an
              ----------------------------------
Incentive Stock Option, there will be no regular federal income tax liability
upon the exercise of the Option, although the excess, if any, of the fair market
value of the Shares on the date of exercise over the Exercise Price will be
treated as an item of alternative minimum taxable income for federal tax
purposes and may subject Optionee to the alternative minimum tax in the year of
exercise.

          (b) Exercise of Nonstatutory Stock Option.  If this Option does not
              -------------------------------------
qualify as an Incentive Stock Option, Optionee may incur regular federal income
tax liability upon the exercise of the Option.  Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the fair market value of the Shares on the date of
exercise over the Exercise Price.  In addition, if Optionee is an employee of
the Company, the Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

          (c) Disposition of Shares.  If this Option is an Incentive Stock
              ---------------------
Option and if Shares transferred pursuant to the Option are held for more than
one year after exercise and more than two years after the Date of Grant, any
gain realized on disposition of the Shares will be treated as long-term capital
gain for federal income tax purposes.  If Shares purchased under an Incentive
Stock Option are disposed of before the end of either of such two holding
periods, then any gain realized on such disposition will be treated as
compensation income (taxable at ordinary income rates) to the extent of the
excess, if any, of the lesser of (i) the fair market value of the Shares on the
date of exercise, or (ii) the sales proceeds, over the Exercise Price.  If this
Option is a Nonstatutory Stock Option, then gain realized on the disposition of
Shares will be treated as long-term or short-term capital gain depending on
whether or not the disposition occurs more than one year after the exercise
date.  In the case of either an Incentive Stock Option or a Nonstatutory Stock
Option, the long-term capital gain will be taxed for federal income tax and
alternative minimum tax purposes as a maximum rate of 20% if the Shares are held
more than one year after exercise.

          (d) Notice of Disqualifying Disposition.  If the Option granted to
              -----------------------------------
Optionee in this Agreement is an Incentive Stock Option, and if Optionee sells
or otherwise disposes of any of the Shares acquired pursuant to the Incentive
Stock Option on or before the later of (i) the date two years after the Date of
Grant, or (ii) the date one year after transfer of such Shares to Optionee upon
exercise of the Incentive Stock Option, Optionee shall notify the Company in
writing within thirty (30) days after the date of any such disposition.
Optionee agrees that Optionee may be subject to income tax withholding by the
Company on the compensation income recognized by Optionee from the early
disposition by payment in cash or out of the current earnings paid to Optionee.

     13.  Withholding Tax Obligations.
          ---------------------------

                                      -4-
<PAGE>

          (a) General Withholding Obligations.  As a condition to the exercise
              -------------------------------
of Option granted hereunder, Optionee shall make such arrangements as the
Administrator may require for the satisfaction of any federal, state, local or
foreign withholding tax obligations that may arise in connection with the
exercise, receipt or vesting of the Option.  The Company shall not be required
to issue any Shares under the Plan until such obligations are satisfied.
Optionee understands that, upon exercising a Nonstatutory Stock Option, he or
she will recognize income for tax purposes in an amount equal to the excess of
the then Fair Market Value of the Shares over the Exercise Price.  If Optionee
is an employee, the Company will be required to withhold from Optionee's
compensation, or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income.
Additionally, Optionee may at some point be required to satisfy tax withholding
obligations with respect to the disqualifying disposition of an Incentive Stock
Option. Optionee shall satisfy his or her tax withholding obligation arising
upon the exercise of this Option by one or some combination of the following
methods:  (i) by cash or check payment, (ii) out of Optionee's current
compensation, (iii) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares which (A) in the case of Shares previously
acquired from the Company, have been owned by Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value determined as of the
applicable Tax Date (as defined in Section 11(c) below) on the date of surrender
equal to the amount required to be withheld, or (iv) by electing to have the
Company withhold from the Shares to be issued upon exercise of the Option that
number of Shares having a Fair Market Value determined as of the applicable Tax
Date equal to the amount required to be withheld.

          (b) Stock Withholding to Satisfy Withholding Tax Obligations.  In the
              --------------------------------------------------------
event the Administrator allows Optionee to satisfy his or her tax withholding
obligations as provided in Section 11(a)(iii) or (iv) above, such satisfaction
must comply with the requirements of this Section (11)(b) and all Applicable
Laws.  All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

             (i) the election must be made on or prior to the applicable Tax
Date (as defined in Section 11(c) below);

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

            (iii) all elections shall be subject to the consent or
disapproval of the Administrator.

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

          (c) Definitions.  For purposes of this Section 11, the Fair Market
              -----------
Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined under the applicable laws (the
"Tax Date").
 --------

     14.  Signature.  This Stock Option Agreement shall be deemed executed by
          ---------
the Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

                             STOCK OPTION AGREEMENT
                             ----------------------

     1.  Grant of Option.
         ---------------

          (a) General Terms.  HealthCentral.com (the "Company"), hereby grants
              -------------                           -------
to the Optionee named in the Notice of Stock Option Grant attached to this
Agreement ("Optionee"), an option (the "Option") to purchase the total number of
            --------                    ------
shares of Common Stock (the "Shares") set forth in the Notice of Stock Option
                             ------
Grant, at the exercise price per share set forth in the Notice of Stock Option
Grant (the "Exercise Price") subject to the terms, definitions and provisions of
            --------------
the 1999 Stock Plan (the "Plan") adopted by the Company, which is incorporated
                          ----
in this Agreement by reference.  In the event of a conflict between the terms of
the Plan and the terms of this Agreement, the terms of the Plan shall govern.
Unless otherwise defined in this Agreement, the terms used in this Agreement
shall have the meanings defined in the Plan.

          (b) Tax Status of Option.  Unless and to the extent designated a
              --------------------
Nonstatutory Stock Option in the Notice of Stock Option Grant, this Option is
intended to be an Incentive Stock Option as defined in Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), to the maximum extent
                                                ----
permitted under applicable tax law.  If any portion of this Option is designated
as an Incentive Stock Option it shall qualify as such only to the extent that
the aggregate fair market value of the Shares (generally, the Option's exercise
price) subject to this Option (and all other Incentive Stock Options granted to
Optionee by the Company or any Parent or Subsidiary) that first become
exercisable in any calendar year does not exceed $100,000.  To the extent that
the aggregate fair market value of such Shares exceeds $100,000, the Shares in
excess of such limit shall be treated as subject to a Nonstatutory Stock Option,
in accordance with Section 5 of the Plan.

     2.  Exercise of Option.  This Option shall be exercisable during its term
         ------------------
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Sections 9 and 10 of the Plan as follows:

          (a)  Right to Exercise.
               -----------------

          (i)    This Option may not be exercised for a fraction of a share.

          (ii)   In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by this
Section 2 and by Sections 6, 7 and 8 below.

          (iii)  In no event may this Option be exercised after the Expiration
Date of the Option as set forth in the Notice of Stock Option Grant.

          (b)  Method of Exercise.
               ------------------

          (i) This Option shall be exercisable by delivering to the Company a
written notice of exercise (in the form attached as Exhibit A) which shall state
                                                    ---------
the election to exercise the Option, the number of Shares in respect of which
the Option is being exercised, and such other representations and agreements as
to the holder's investment intent with respect to such Shares of Common Stock as
may be required by the Company pursuant to the provisions of the Plan.  Such
written notice shall be signed by Optionee and shall be delivered in person or
by certified mail to the Secretary of the Company.  The written notice shall be
accompanied by payment of the Exercise Price.  This Option

                                      -1-
<PAGE>

shall be deemed to be exercised upon receipt by the Company of such written
notice accompanied by the Exercise Price.

          (ii) As a condition to the exercise of this Option, Optionee agrees to
make adequate provision for federal, state or other tax withholding obligations,
if any, which arise upon the exercise of the Option or disposition of Shares,
whether by withholding, direct payment to the Company, or otherwise.

          (iii)  No Shares will be issued pursuant to the exercise of an Option
unless such issuance and such exercise shall comply with all relevant provisions
of law and the requirements of any stock exchange upon which the Shares may then
be listed.  Assuming such compliance, for income tax purposes the Shares shall
be considered transferred to Optionee on the date on which the Option is
exercised with respect to such Shares.

     3.  Optionee's Representations.  In the event the Shares purchasable
         --------------------------
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), at the time this
                                         --------------
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.

     4.  Method of Payment.  Payment of the Exercise Price shall be by any of
         -----------------
the following, or a combination of the following, at the election of Optionee:
(a) cash; (b) check; (c) surrender of other Shares of Common Stock of the
Company that (i) either have been owned by Optionee for more than six (6) months
on the date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which the Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.

     5.  Restrictions on Exercise.  This Option may not be exercised until such
         ------------------------
time as the Plan has been approved by the stockholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("Regulation G") as
                                                          ------------
promulgated by the Federal Reserve Board.  As a condition to the exercise of
this Option, the Company may require Optionee to make any representation and
warranty to the Company as may be required by any applicable law or regulation.

     6.  Termination of Relationship.  In the event of termination of Optionee's
         ---------------------------
Continuous Service Status, Optionee may, to the extent otherwise so entitled at
the date of such termination (the "Termination Date"), exercise this Option
                                   ----------------
during the Termination Period set out in the Notice of Stock Option Grant.  To
the extent that Optionee was not entitled to exercise this Option at the date of
such termination, or if Optionee does not exercise this Option within the time
specified in the Notice of Stock Option Grant, the Option shall terminate.

     7.  Disability of Optionee.  Notwithstanding the provisions of Section 6
         ----------------------
above, in the event of termination of Optionee's Continuous Service Status as a
result of total and permanent disability (as

                                      -2-
<PAGE>

defined in Section 22(e)(3) of the Code), Optionee may, but only within twelve
(12) months from the date of termination of employment (but in no event later
than the Expiration Date of the Option as set forth in the Notice of Stock
Option Grant), exercise the Option to the extent otherwise so entitled at the
date of such termination. To the extent that Optionee was not entitled to
exercise the Option at the date of termination, or if Optionee does not exercise
such Option (to the extent otherwise so entitled) within the time specified in
this Agreement, the Option shall terminate.

     8.  Death of Optionee.  In the event of the death of Optionee (a) during
         -----------------
the term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Service Status since the date of grant of the Option,
or (b) within thirty (30) days after the termination of Optionee's Continuous
Service Status, the Option may be exercised, at any time within twelve (12)
months following the date of death (but in no event later than the Expiration
Date of the Option as set forth in the Notice of Stock Option Grant), by
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of death or termination, as applicable.  To the extent
that Optionee was not entitled to exercise this Option at the date of death or
termination, as applicable, or if Optionee's estate or the person who acquired
the right to exercise the Option as a result of Optionee's death does not
exercise this Option within the time specified in the Notice of Stock Option
Grant, the Option shall terminate

     9.  Non-Transferability of Option.  This Option may not be transferred in
         -----------------------------
any manner otherwise than by will or by the laws of descent or distribution.
The designation of a beneficiary does not constitute a transfer.  An Option may
be exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section.  The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.

     10.  Term of Option.  This Option may be exercised only within the term set
          --------------
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the Plan and the terms of this Option.

     11.  No Additional Employment Rights.  Optionee understands and agrees that
          -------------------------------
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an Employee or Consultant at the will of the Company (not through
the act of being hired, being granted this Option or acquiring Shares under this
Agreement).  Optionee further acknowledges and agrees that nothing in this
Agreement or the Plan shall confer upon Optionee any right with respect to
continuation as an Employee or Consultant with the Company, nor shall it
interfere in any way with his or her right or the Company's right to terminate
his or her employment or consulting relationship at any time, with or without
cause.

     12.  Tax Consequences.  Optionee acknowledges that he or she has read the
          ----------------
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE AND
DOES NOT ADDRESS STATE, LOCAL OR FOREIGN ISSUES, AND THAT THE TAX LAWS AND
REGULATIONS SUMMARIZED ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT HIS OR
HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a) Exercise of Incentive Stock Option.  If this Option is an
              ----------------------------------
Incentive Stock Option, there will be no regular federal income tax liability
upon the exercise of the Option, although the excess, if any, of the fair market
value of the Shares on the date of exercise over the Exercise Price will be
treated as an item of alternative minimum taxable income for federal tax
purposes and may subject Optionee to the alternative minimum tax in the year of
exercise.

                                      -3-
<PAGE>

          (b) Exercise of Nonstatutory Stock Option.  If this Option does not
              -------------------------------------
qualify as an Incentive Stock Option, Optionee may incur regular federal income
tax liability upon the exercise of the Option.  Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the fair market value of the Shares on the date of
exercise over the Exercise Price.  In addition, if Optionee is an employee of
the Company, the Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

          (c) Disposition of Shares.  If this Option is an Incentive Stock
              ---------------------
Option and if Shares transferred pursuant to the Option are held for more than
one year after exercise and more than two years after the Date of Grant, any
gain realized on disposition of the Shares will be treated as long-term capital
gain for federal income tax purposes.  If Shares purchased under an Incentive
Stock Option are disposed of before the end of either of such two holding
periods, then any gain realized on such disposition will be treated as
compensation income (taxable at ordinary income rates) to the extent of the
excess, if any, of the lesser of (i) the fair market value of the Shares on the
date of exercise, or (ii) the sales proceeds, over the Exercise Price.  If this
Option is a Nonstatutory Stock Option, then gain realized on the disposition of
Shares will be treated as long-term or short-term capital gain depending on
whether or not the disposition occurs more than one year after the exercise
date.  In the case of either an Incentive Stock Option or a Nonstatutory Stock
Option, the long-term capital gain will be taxed for federal income tax and
alternative minimum tax purposes as a maximum rate of 20% if the Shares are held
more than one year after exercise.

          (d) Notice of Disqualifying Disposition.  If the Option granted to
              -----------------------------------
Optionee in this Agreement is an Incentive Stock Option, and if Optionee sells
or otherwise disposes of any of the Shares acquired pursuant to the Incentive
Stock Option on or before the later of (i) the date two years after the Date of
Grant, or (ii) the date one year after transfer of such Shares to Optionee upon
exercise of the Incentive Stock Option, Optionee shall notify the Company in
writing within thirty (30) days after the date of any such disposition.
Optionee agrees that Optionee may be subject to income tax withholding by the
Company on the compensation income recognized by Optionee from the early
disposition by payment in cash or out of the current earnings paid to Optionee.

     13.  Withholding Tax Obligations.
          ---------------------------

          (a) General Withholding Obligations.  As a condition to the exercise
              -------------------------------
of Option granted hereunder, Optionee shall make such arrangements as the
Administrator may require for the satisfaction of any federal, state, local or
foreign withholding tax obligations that may arise in connection with the
exercise, receipt or vesting of the Option.  The Company shall not be required
to issue any Shares under the Plan until such obligations are satisfied.
Optionee understands that, upon exercising a Nonstatutory Stock Option, he or
she will recognize income for tax purposes in an amount equal to the excess of
the then Fair Market Value of the Shares over the Exercise Price.  If Optionee
is an employee, the Company will be required to withhold from Optionee's
compensation, or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income.
Additionally, Optionee may at some point be required to satisfy tax withholding
obligations with respect to the disqualifying disposition of an Incentive Stock
Option. Optionee shall satisfy his or her tax withholding obligation arising
upon the exercise of this Option by one or some combination of the following
methods:  (i) by cash or check payment, (ii) out of Optionee's current
compensation, (iii) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares which (A) in the case of Shares previously
acquired from the Company, have been owned by Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value determined as of the
applicable Tax Date (as defined in Section 11(c) below) on the date of surrender
equal to the amount required to be

                                      -4-
<PAGE>

withheld, or (iv) by electing to have the Company withhold from the Shares to be
issued upon exercise of the Option that number of Shares having a Fair Market
Value determined as of the applicable Tax Date equal to the amount required to
be withheld.

          (b) Stock Withholding to Satisfy Withholding Tax Obligations.  In the
              --------------------------------------------------------
event the Administrator allows Optionee to satisfy his or her tax withholding
obligations as provided in Section 11(a)(iii) or (iv) above, such satisfaction
must comply with the requirements of this Section (11)(b) and all Applicable
Laws.  All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (i)    the election must be made on or prior to the applicable Tax
Date (as defined in Section 11(c) below);

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

          (iii)  all elections shall be subject to the consent or
disapproval of the Administrator.

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

          (c) Definitions.  For purposes of this Section 11, the Fair Market
              -----------
Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined under the applicable laws (the
"Tax Date").
 --------

     14.  Signature.  This Stock Option Agreement shall be deemed executed by
          ---------
the Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

                                      -4-
<PAGE>

Applicable Laws, the Board may authorize one or more officers to grant Options
or Stock Purchase Rights to Employees and Consultants.

          (b) Administration with respect to Reporting Persons.  With respect to
              ------------------------------------------------
Options granted to Reporting Persons and Named Executives, the Plan may (but
need not) be administered so as to permit such Options to qualify for the
exemption set forth in Rule 16b-3(d) and to qualify as performance-based
compensation under Section 162(m) of the Code.

          (c) Committee Composition.  If a Committee has been appointed pursuant
              ---------------------
to this Section 4, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board.  From time to time the Board may
increase the size of any Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies (however caused) and remove all members of a Committee
and thereafter directly administer the Plan, all to the extent permitted by the
Applicable Laws and, in the case of a Committee administering the Plan pursuant
to Section 4(b) above, to the extent permitted or required by Rule 16b-3 and
Section 162(m) of the Code.

          (d) Powers of the Administrator.  Subject to the provisions of the
              ---------------------------
Plan and in the case of a Committee, the specific duties delegated by the Board
to such Committee, the Administrator shall have the authority, in its
discretion:

             (i) to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(p) of the Plan;

            (ii) to select the Employees and Consultants to whom Options and
Stock Purchase Rights or any combination thereof may from time to time be
granted;

            (iii) to determine whether and to what extent Options and Stock
Purchase Rights or any combination thereof are granted;

              (iv) to determine the number of Shares of Common Stock to be
covered by each such award granted;

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

              (vi) to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any award granted hereunder, which terms and
conditions include but are not limited to the exercise or purchase price, the
time or times when Options or Stock Purchase Rights may be exercised (which may
be based on performance criteria), any vesting acceleration or waiver of
forfeiture restrictions, and any restriction or limitation regarding any Option,
Optioned Stock, Stock Purchase Right or Restricted Stock, based in each case on
such factors as the Administrator, in its sole discretion, shall determine;

             (vii) to determine whether and under what circumstances an Option
may be settled in cash under Section 10(f) instead of Common Stock;

                                      -5-
<PAGE>

            (viii) to reduce the exercise price of any Option to the then
current Fair Market Value if the Fair Market Value of the Common Stock covered
by such Option shall have declined since the date the Option was granted and to
make any other amendments or adjustments to any Option that the Administrator
determines, in its discretion and under the authority granted to it under the
Plan, to be necessary or advisable, provided however that no amendment or
adjustment to an Option that would materially and adversely affect the rights of
any Optionee shall be made without the prior written consent of the Optionee;

             (ix) to determine the terms and restrictions applicable to Stock
Purchase Rights and the Restricted Stock purchased by exercising such Stock
Purchase Rights;

              (x) to initiate an Option Exchange Program;

             (xi) to construe and interpret the terms of the Plan and awards
granted under the Plan; and

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

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

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

          (a) Recipients of Grants.  Nonstatutory Stock Options and Stock
              --------------------
Purchase Rights may be granted to Employees and Consultants.  Incentive Stock
Options may be granted only to Employees; provided however that Employees of
Affiliates shall not be eligible to receive Incentive Stock Options.  An
Employee or Consultant who has been granted an Option or Stock Purchase Right
may, if he or she is otherwise eligible, be granted additional Options or Stock
Purchase Rights.

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

          (c) At-Will Relationship.  The Plan shall not confer upon the holder
              --------------------
of any Option or Stock Purchase Right any right with respect to continuation of
employment or consulting relationship with the Company, nor shall it interfere
in any way with such holder's

                                      -6-
<PAGE>

right or the Company's right to terminate his or her employment or consulting
relationship at any time, with or without cause.

     6.  Term of Plan.  The Plan shall become effective upon its adoption by the
         ------------
Board.  It shall continue in effect for a term of ten years unless sooner
terminated under Section 15 of the Plan.

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

     8.  Limitations on Grants to Employees.  Subject to adjustment as provided
         ----------------------------------
in Section 13 below, the maximum number of Shares which may be subject to
Options or Stock Purchase Rights granted to any one Employee under the Plan for
any fiscal year of the Company shall be 1,250,000 Shares (after giving effect to
the Company's 5-for-4 stock split effected in connection with its
reincorporation under the laws of Delaware and subject to further adjustment as
provided in Section 13 below).

     9.  Option Exercise Price and Consideration.
         ---------------------------------------

          (a) The per share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the Board and
set forth in the Option Agreement, but shall be subject to the following:

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

                   (A) granted to an Employee who, at the time of the grant of
such Incentive Stock Option, owns stock representing more than 10% of the total
combined voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant.

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

              (ii) In the case of a Nonstatutory Stock Option that is granted
prior to the date, if any, upon which the Common Stock becomes a Listed Security
and is:

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

                                      -7-
<PAGE>

                (B) granted to a person who, at the time of the grant of such
Option, is a Named Executive of the Company, the per Share Exercise Price shall
be no less than 100% of the Fair Market Value on the date of grant if such
Option is intended to qualify as performance-based compensation under Section
162(m) of the Code and if not so intended shall be such price as is determined
by the Administrator.

                (C) granted to any other eligible person, the per Share exercise
price shall be no less than 85% of the Fair Market Value per Share on the date
of grant if required by the Applicable Laws.

           (iii)  Notwithstanding the foregoing, Options may be granted with a
per Share exercise price other than as required above pursuant to a merger or
other corporate transaction.

          (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) cancellation of indebtedness, (5) other Shares
that (x) in the case of Shares acquired upon exercise of an Option, have been
owned by the Optionee for more than six months on the date of surrender or such
other period as may be required to avoid a charge to the Company's earnings, and
(y) have a Fair Market Value on the date of surrender equal to the aggregate
exercise price of the Shares as to which such Option shall be exercised, (6)
authorization for the Company to retain from the total number of Shares as to
which the Option is exercised that number of Shares having a Fair Market Value
on the date of exercise equal to the exercise price for the total number of
Shares as to which the Option is exercised, (7) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price and any applicable income or employment taxes, (8) delivery of an
irrevocable subscription agreement for the Shares that irrevocably obligates the
option holder to take and pay for the Shares not more than twelve months after
the date of delivery of the subscription agreement, (9) any combination of the
foregoing methods of payment, or (10) such other consideration and method of
payment for the issuance of Shares to the extent permitted under the Applicable
Laws.  In making its determination as to the type of consideration to accept,
the Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company and the Administrator may refuse to
accept a particular form of consideration at the time of any Option exercise if
it determines, in its sole discretion, that acceptance of such form of
consideration is not in the best interests of the Company at such time.

     10.  Exercise of Option.
          ------------------

          (a) Procedure for Exercise; Rights as a Shareholder.  Any Option
              -----------------------------------------------
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator and reflected in the Option Agreement, which
may include vesting requirements and/or performance criteria with respect to the
Company and/or the Optionee; provided however, that any Option granted prior to
the date, if any, upon which the Common Stock becomes a

                                      -8-
<PAGE>

Listed Security shall become exercisable at the rate of at least 20% per year
over five years from the date the Option is granted if required by the
Applicable Laws. In the event that any of the Shares issued upon exercise of an
Option (which exercise occurs prior to the date, if any, upon which the Common
Stock becomes a Listed Security) should be subject to a right of repurchase in
the Company's favor, such repurchase right shall lapse at the rate of at least
20% per year over five years from the date the Option is granted if required by
the Applicable Laws. Notwithstanding the above, in the case of an Option granted
to an officer, Director or Consultant of the Company or any Parent or Subsidiary
of the Company, the Option may become fully exercisable, or a repurchase right,
if any, in favor of the Company shall lapse, at any time or during any period
established by the Administrator. The Administrator shall have the discretion to
determine whether and to what extent the vesting of Options shall be tolled
during any unpaid leave of absence; provided however that in the absence of such
determination, vesting of Options shall be tolled during any such leave.

     An Option may not be exercised for a fraction of a Share.

     An Option shall be deemed exercised when written notice of such exercise
has been given to the Company in accordance with the terms of the Option by the
person entitled to exercise the Option and the Company has received full payment
for the Shares with respect to which the Option is exercised.  Full payment may,
as authorized by the Administrator, consist of any consideration and method of
payment allowable under Section 9(b) of the Plan.  Until the issuance (as
evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company) of the stock certificate evidencing
such Shares, no right to vote or receive dividends or any other rights as a
shareholder shall exist with respect to the Optioned Stock, not withstanding the
exercise of the Option.  The Company shall issue (or cause to be issued) such
stock certificate promptly upon exercise of the Option.  No adjustment will be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 13 of the
Plan.

     Exercise of an Option in any manner shall result in a decrease in the
number of Shares that thereafter may be available, both for purposes of the Plan
and for sale under the Option, by the number of Shares as to which the Option is
exercised.

          (b) Termination of Employment or Consulting Relationship.  Subject to
              ----------------------------------------------------
Section 10(c) below, in the event of termination of an Optionee's Continuous
Status as an Employee or Consultant with the Company, such Optionee may, but
only within three months (or such other period of time not less than 30 days as
is determined by the Administrator, with such determination in the case of an
Incentive Stock Option being made at the time of grant of the Option) after the
date of such termination (but in no event later than the expiration date of the
term of such Option as set forth in the Option Agreement), exercise his or her
Option to the extent that the Optionee was entitled to exercise it at the date
of such termination.  To the extent that the Optionee was not entitled to
exercise the Option at the date of such termination, or if the Optionee does not
exercise such Option to the extent so entitled within the time specified herein,
the Option shall terminate and the Optioned Stock underlying the unexercised
portion of the Option shall revert to the Plan.  No termination shall be deemed
to occur and this Section 10(b)

                                      -9-
<PAGE>

shall not apply if (i) the Optionee is a Consultant who becomes an Employee, or
(ii) the Optionee is an Employee who becomes a Consultant.

          (c)  Disability of Optionee.
               ----------------------

               (i) Notwithstanding Section 10(b) above, in the event of
termination of an Optionee's Continuous Status as an Employee or Consultant as a
result of his or her total and permanent disability (within the meaning of
Section 22(e)(3) of the Code), such Optionee may, but only within twelve months
from the date of such termination (but in no event later than the expiration
date of the term of such Option as set forth in the Option Agreement), exercise
the Option to the extent otherwise entitled to exercise it at the date of such
termination. To the extent that the Optionee was not entitled to exercise the
Option at the date of termination, or if the Optionee does not exercise such
Option to the extent so entitled within the time specified herein, the Option
shall terminate and the Optioned Stock underlying the unexercised portion of the
Option shall revert to the Plan.

              (ii) In the event of termination of an Optionee's Continuous
Status as an Employee or Consultant as a result of a disability which does not
fall within the meaning of total and permanent disability (as set forth in
Section 22(e)(3) of the Code), such Optionee may, but only within six months
from the date of such termination (but in no event later than the expiration
date of the term of such Option as set forth in the Option Agreement), exercise
the Option to the extent otherwise entitled to exercise it at the date of such
termination. However, to the extent that such Optionee fails to exercise an
Option which is an Incentive Stock Option (within the meaning of Section 422 of
the Code) within three months of the date of such termination, the Option will
not qualify for Incentive Stock Option treatment under the Code. To the extent
that the Optionee was not entitled to exercise the Option at the date of
termination, or if the Optionee does not exercise such Option to the extent so
entitled within six months from the date of termination, the Option shall
terminate and the Optioned Stock underlying the unexercised portion of the
Option shall revert to the Plan.

          (d) Death of Optionee.  In the event of the death of an Optionee
              -----------------
during the period of Continuous Status as an Employee or Consultant since the
date of grant of the Option, or within 30 days following termination of the
Optionee's Continuous Status as an Employee or Consultant, the Option may be
exercised, at any time within six months following the date of death (but in no
event later than the expiration date of the term of such Option as set forth in
the Option Agreement), by such Optionee's estate or by a person who acquired the
right to exercise the Option by bequest or inheritance, but only to the extent
of the right to exercise that had accrued at the date of death or, if earlier,
the date of termination of the Optionee's Continuous Status as an Employee or
Consultant.  To the extent that the Optionee was not entitled to exercise the
Option at the date of death or termination, as the case may be, or if the
Optionee does not exercise such Option to the extent so entitled within the time
specified herein, the Option shall terminate and the Optioned Stock underlying
the unexercised portion of the Option shall revert to the Plan.

          (e) Extension of Exercise Period.  The Administrator shall have full
              ----------------------------
power and authority to extend the period of time for which an Option is to
remain exercisable following

                                      -10-
<PAGE>

termination of an Optionee's Continuous Status as an Employee or Consultant from
the periods set forth in Sections 10(b), 10(c) and 10(d) above or in the Option
Agreement to such greater time as the Board shall deem appropriate, provided,
that in no event shall such option be exercisable later than the date of
expiration of the term of such Option as set forth in the Option Agreement.

          (f) Buy-Out Provisions.  The Administrator may at any time offer to
              ------------------
buy out for a payment in cash or Shares an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time such offer is made.

     11.  Stock Purchase Rights.
          ---------------------

          (a) Rights to Purchase.  Stock Purchase Rights may be issued either
              ------------------
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan.  After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing of the terms, conditions and restrictions related to the
offer, including the number of Shares that such person shall be entitled to
purchase, the price to be paid (which price, if required by the Applicable Laws,
shall not be less than 85% of the Fair Market Value of the Shares as of the date
of the offer, or, in the case of a person owning stock representing more than
10% of the total combined voting power of all classes of stock of the Company or
any Parent or Subsidiary, the price shall not be less than 100% of the Fair
Market Value of the Shares as of the date of the offer), and the time within
which such person must accept such offer, which shall in no event exceed 30 days
from the date upon which the Administrator made the determination to grant the
Stock Purchase Right.  The offer shall be accepted by execution of a Restricted
Stock Purchase Agreement in the form determined by the Administrator.

          (b) Repurchase Option.  Unless the Administrator determines otherwise,
              -----------------
the Restricted Stock Purchase Agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's employment with the Company for any reason (including death or
disability).  The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original purchase price paid by
the purchaser and may be paid by cancellation of any indebtedness of the
purchaser to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine; provided, however, that with respect to an Optionee
who is not an officer, director or Consultant of the Company or of any Parent or
Subsidiary of the Company, it shall lapse at a minimum rate of 20% per year if
required by the Applicable Laws.

          (c) Other Provisions.  The Restricted Stock Purchase Agreement shall
              ----------------
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.  In
addition, the provisions of Restricted Stock Purchase Agreements need not be the
same with respect to each purchaser.

          (d) Rights as a Shareholder.  Once the Stock Purchase Right is
              -----------------------
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder

                                      -11-
<PAGE>

when his or her purchase is entered upon the records of the duly authorized
transfer agent of the Company. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Stock Purchase
Right is exercised, except as provided in Section 13 of the Plan.

     12.  Taxes.
          -----

          (a) As a condition of the exercise of an Option or Stock Purchase
Right granted under the Plan, the Participant (or in the case of the
Participant's death, the person exercising the Option or Stock Purchase Right)
shall make such arrangements as the Administrator may require for the
satisfaction of any applicable federal, state, local or foreign withholding tax
obligations that may arise in connection with the exercise of Option or Stock
Purchase Right and the issuance of Shares.  The Company shall not be required to
issue any Shares under the Plan until such obligations are satisfied.

          (b) In the case of an Employee and in the absence of any other
arrangement, the Employee shall be deemed to have directed the Company to
withhold or collect from his or her compensation an amount sufficient to satisfy
such tax obligations from the next payroll payment otherwise payable after the
date of an exercise of the Option or Stock Purchase Right.

          (c) This Section 12(c) shall apply only after the date, if any, upon
which the Common Stock becomes a Listed Security.  In the case of Participant
other than an Employee (or in the case of an Employee where the next payroll
payment is not sufficient to satisfy such tax obligations, with respect to any
remaining tax obligations), in the absence of any other arrangement and to the
extent permitted under the Applicable Laws, the Participant shall be deemed to
have elected to have the Company withhold from the Shares to be issued upon
exercise of the Option or Stock Purchase Right that number of Shares having a
Fair Market Value determined as of the applicable Tax Date (as defined below)
equal to the amount required to be withheld.  For purposes of this Section 12,
the Fair Market Value of the Shares to be withheld shall be determined on the
date that the amount of tax to be withheld is to be determined under the
Applicable Laws (the "Tax Date").
                      --------

          (d) If permitted by the Administrator, in its discretion, a
Participant may satisfy his or her tax withholding obligations upon exercise of
an Option or Stock Purchase Right by surrendering to the Company Shares that (i)
in the case of Shares previously acquired from the Company, have been owned by
the Participant for more than six (6) months on the date of surrender, and (ii)
have a Fair Market Value determined as of the applicable Tax Date equal to the
amount required to be withheld.

          (e) Any election or deemed election by a Participant to have Shares
withheld to satisfy tax withholding obligations under Section 12(c) or (d) above
shall be irrevocable as to the particular Shares as to which the election is
made and shall be subject to the consent or disapproval of the Administrator.
Any election by a Participant under Section 12(d) above must be made on or prior
to the applicable Tax Date.

                                      -12-
<PAGE>

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

     13.  Adjustments Upon Changes in Capitalization, Merger or Certain Other
          -------------------------------------------------------------------
Transactions.
------------

          (a) Changes in Capitalization.  Subject to any required action by the
              -------------------------
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock that have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or that have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right and the number of Shares set forth in Section 8 above, as well as
the price per share of Common Stock covered by each such outstanding Option or
Stock Purchase Right, shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination, recapitalization or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option or Stock
Purchase Right.

          (b) Dissolution or Liquidation.  In the event of the proposed
              --------------------------
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least 15 days prior to such proposed action.  To the extent it has not been
previously exercised, the Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

          (c) Corporate Transaction; Change in Control.  In the event of a
              ----------------------------------------
Corporate Transaction or a Change in Control, each outstanding Option and Stock
Purchase Right shall be assumed or an equivalent option or right shall be
substituted by the successor corporation or a Parent or Subsidiary of such
successor corporation (such entity, the "Successor Corporation"), unless the
                                         ---------------------
Successor Corporation does not agree to assume the outstanding Options or Stock
Purchase Rights or to substitute equivalent options or rights, in which case
such Options or Stock Purchase Rights shall terminate upon consummation of the
transaction.  In the event of a transaction that qualifies as a Change of
Control (i) in which outstanding awards are being continued, assumed or
substituted, the vesting and exercisability of each outstanding Option and Stock
Purchase Right shall accelerate such that the Options and Stock Purchase Rights
shall become vested and exercisable to the extent of 50% of the Shares then
unvested, and any repurchase right of the Company with respect to Shares issued
upon exercise of an Option or

                                      -13-
<PAGE>

Stock Purchase Right shall lapse as to 50% of the Shares subject to such
repurchase right prior to consummation of the Change of Control, and (ii) in
which outstanding awards are terminating, the vesting and exercisability of each
outstanding Option and Stock Purchase Right shall accelerate such that the
Options and Stock Purchase Rights shall become vested and exercisable to the
extent of 100% of the Shares then unvested, and any repurchase right of the
Company with respect to Shares issued upon exercise of an Option or Stock
Purchase Right shall lapse as to 100% of the Shares subject to such repurchase
right prior to consummation of the Change of Control, in each case at such time
and upon such conditions as the Administrator shall determine. To the extent
that an Option or Stock Purchase Right is not exercised prior to consummation of
a Corporate Transaction or Change of Control in which the Option or Stock
Purchase Right is terminating, such Option or Stock Purchase Right shall
terminate upon such consummation.

          For purposes of this Section 13(c), an Option or a Stock Purchase
Right shall be considered assumed, without limitation, if, at the time of
issuance of the stock or other consideration upon such Change in Control, each
holder of an Option or Stock Purchase Right would be entitled to receive upon
exercise of the Option or Stock Purchase Right the same number and kind of
shares of stock or the same amount of property, cash or securities as such
holder would have been entitled to receive upon the occurrence of the
transaction if the holder had been, immediately prior to such transaction, the
holder of the number of Shares of Common Stock covered by the Option or the
Stock Purchase Right at such time (after giving effect to any adjustments in the
number of Shares covered by the Option or Stock Purchase Right as provided for
in this Section 13); provided however that if such consideration received in the
Change in Control was not solely common stock of the successor corporation or
its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon exercise of the
Option to be solely common stock of the successor corporation or its Parent
equal to the Fair Market Value of the per Share consideration received by
holders of Common Stock in the transaction.

          (d) Certain Distributions.  In the event of any distribution to the
              ---------------------
Company's shareholders of securities of any other entity or other assets (other
than dividends payable in cash or stock of the Company) without receipt of
consideration by the Company, the Administrator may, in its discretion,
appropriately adjust the price per Share of Common Stock covered by each
outstanding Option or Stock Purchase Right to reflect the effect of such
distribution.

          (e) Limitation on Payments.  In the event that the vesting
              ----------------------
acceleration provided for in subsection (c) above (x) constitutes "parachute
payments" within the meaning of Section 280G of the Internal Revenue Code (the

"Code"), and (y) but for this Section 13(e) would be subject to the excise tax
-----
imposed by Section 4999 of the Code (or any corresponding provisions of state
income tax law), then such vesting acceleration shall be either

                     (A)  delivered in full, or

                     (B)  delivered as to such lesser extent which would result
in no portion of such severance benefits being subject to excise tax under Code
Section 4999,

whichever of the foregoing amounts, taking into account the applicable federal,
state and local income taxes and the excise tax imposed by Code Section 4999,
results in the receipt by the optionee on an after-tax basis of the greater
amount of acceleration benefits, notwithstanding that all or some portion of
such benefits may be taxable under Code Section 4999. Any determination required
under this Section 13(e) shall be made in writing by the Company's independent
accountants or other outside tax advisors, whose determination shall be based on
factual assertions provided by the Company, and which will be conclusive and
binding for all purposes on the Company and the optionee. In the event that (A)
above applies, then the optionee shall be responsible for any excise taxes
imposed with respect to such benefits. In the event that (B) above applies, then
each benefit provided hereunder shall be proportionately reduced to the extent
necessary to avoid imposition of such excise taxes.

     14.  Non-Transferability of Options and Stock Purchase Rights.  Options and
          --------------------------------------------------------
Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised or purchased during the lifetime of
the Optionee or the holder of Stock Purchase Rights only by the Optionee or
holder of Stock Purchase Rights; provided however that the Administrator may in
its discretion grant transferable Nonstatutory Stock Options pursuant to Option
Agreements, or amend outstanding Option Agreements to allow for transferability
by, specifying (i) the manner in which such Nonstatutory Stock Options are
transferable and (ii) that any such transfer shall be subject to the Applicable
Laws.  The designation of a beneficiary by an Optionee will not constitute a
transfer.  An Option or Stock Purchase Right may be exercised, during the
lifetime of the holder of the Option or Stock Purchase Right, only by such
holder or a transferee permitted by this Section 14.

                                      -14-
<PAGE>

     15.  Time of Granting Options and Stock Purchase Rights.  The date of grant
          --------------------------------------------------
of an Option or Stock Purchase Right shall, for all purposes, be the date on
which the Administrator makes the determination granting such Option or Stock
Purchase Right, or such other date as is determined by the Board; provided,
however, that in the case of any Incentive Stock Option, the grant date shall be
the later of the date on which the Administrator makes the determination
granting such Incentive Stock Option or the date of commencement of the
Optionee's employment relationship with the Company.  Notice of the
determination shall be given to each Employee or Consultant to whom an Option or
Stock Purchase Right is so granted within a reasonable time after the date of
such grant.

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

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

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

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

     As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by law.

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

                                      -15-
<PAGE>

     19.  Agreements.  Options and Stock Purchase Rights shall be evidenced by
          ----------
written Option Agreements and Restricted Stock Purchase Agreements,
respectively, in such form(s) as the Administrator shall approve from time to
time.

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

     21.  Information and Documents to Optionees and Purchasers.  The Company
          -----------------------------------------------------
shall provide financial statements at least annually to each Optionee and to
each individual who acquired Shares pursuant to the Plan, during the period such
Optionee or purchaser has one or more Options or Stock Purchase Rights
outstanding, and in the case of an individual who acquired Shares pursuant to
the Plan, during the period such individual owns such Shares.  The Company shall
not be required to provide such information if the issuance of Options or Stock
Purchase Rights under the Plan is limited to key employees whose duties in
connection with the Company assure their access to equivalent information.  In
addition, at the time of issuance of any securities under the Plan, the Company
shall provide to the Optionee or the purchaser a copy of the Plan and any
agreement(s) pursuant to which securities granted under the Plan are issued.

                             STOCK OPTION AGREEMENT
                             ----------------------


     1.  Grant of Option.  HealthCentral.com, a California corporation (the
         ---------------
"Company"), hereby grants to _________ ("Optionee"), an option (the "Option") to
-------                                  --------                    ------

the Notice of Stock Option Grant (the "Exercise Price") subject to the terms,
                                       --------------
definitions and provisions of the HealthCentral.com 1998 Stock Plan (the "Plan")
                                                                          ----
adopted by the Company, which is incorporated herein by reference.  Unless
otherwise defined herein, the terms defined in the Plan shall have the same
defined meanings in this Option.

     If designated an Incentive Stock Option, this Option is intended to qualify
as an Incentive Stock Option as defined in Section 422 of the Code.

     2.  Exercise of Option.  This Option shall be exercisable during its Term
         ------------------
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Section 9 of the Plan as follows:

          (a)  Right to Exercise.
               -----------------

               (i)  This Option may not be exercised for a fraction of a share.

               (ii) In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 5, 6 and 7 below, subject to the limitation contained in Section
2(a)(i).

              (iii) In no event may this Option be exercised after the
Expiration Date of this Option as set forth in the Notice of Stock Option Grant.

          (b) Method of Exercise.  This Option shall be exercisable by execution
              ------------------
and delivery of the Exercise Notice and Restricted Stock Purchase Agreement
attached hereto as Exhibit A (the "Exercise Agreement") or of any other form of
                   ---------       ------------------
written notice approved for such purpose by the Company which shall state the
election to exercise the Option, the number of Shares in respect of which the
Option is being exercised, and such other representations and agreements as to
the holder's investment intent with respect to such shares of Common Stock as
may be required by the Company pursuant to the provisions of the Plan.  Such
written notice shall be signed by Optionee and shall be delivered in person or
by certified mail to the Secretary of the Company.  The written notice shall be
accompanied by payment of the Exercise Price.  This Option shall be deemed to be
exercised upon receipt by the Company of such written notice accompanied by the
Exercise Price.
<PAGE>

     No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of
applicable law and the requirements of any stock exchange upon which the Shares
may then be listed.  Assuming such compliance, for income tax purposes the
Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

     3.  Method of Payment.  Payment of the Exercise Price shall be by any of
         -----------------
the following, or a combination thereof, at the election of Optionee:

          (a)  cash or check;

          (b) cancellation of outstanding indebtedness;

          (c) surrender of other shares of Common Stock of the Company which (i)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by Optionee for more than six months on the date of surrender,
and (ii) have a Fair Market Value on the date of surrender equal to the Exercise
Price of the Shares as to which the Option is being exercised; or

          (d) if there is a public market for the Shares and they are registered
under the Exchange Act, delivery of a properly executed exercise notice together
with irrevocable instructions to a broker to deliver promptly to the Company the
amount of sale or loan proceeds required to pay the Exercise Price.

     4.  Restrictions on Exercise.  This Option may not be exercised until such
         ------------------------
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

     5.  Termination of Relationship.  In the event of termination of Optionee's
         ---------------------------
Continuous Status as an Employee or Consultant, Optionee may, to the extent
otherwise so entitled at the date of such termination (the "Termination Date"),
                                                            ----------------
exercise this Option during the Termination Period set forth in the Notice of
Stock Option Grant.  To the extent that Optionee was not entitled to exercise
this Option at such Termination Date, or if Optionee does not exercise this
Option within the Termination Period, the Option shall terminate.

     6.  Disability of Optionee.
         ----------------------

          (a) Notwithstanding the provisions of Section 5 above, in the event of
termination of Optionee's Continuous Status as an Employee or Consultant as a
result of Optionee's total and permanent disability (as defined in Section
22(e)(3) of the Code), Optionee may, but only within twelve months from the
Termination Date (but in no event later than the Expiration Date set forth in
the Notice of Stock Option Grant), exercise this Option to the extent
<PAGE>

Optionee was entitled to exercise it as of such Termination Date. To the extent
that Optionee was not entitled to exercise the Option as of the Termination
Date, or if Optionee does not exercise such Option (to the extent so entitled)
within the time specified in this Section 6(a), the Option shall terminate.

          (b) Notwithstanding the provisions of Section 5 above, in the event of
termination of Optionee's consulting relationship or Continuous Status as an
Employee as a result of disability not constituting a total and permanent
disability (as set forth in Section 22(e)(3) of the Code), Optionee may, but
only within six months from the Termination Date (but in no event later than the
Expiration Date set forth in the Notice of Stock Option Grant), exercise the
Option to the extent Optionee was entitled to exercise it as of such Termination
Date; provided, however, that if this is an Incentive Stock Option and Optionee
fails to exercise this Incentive Stock Option within three months from the
Termination Date, this Option will cease to qualify as an Incentive Stock Option
(as defined in Section 422 of the Code) and Optionee will be treated for federal
income tax purposes as having received ordinary income at the time of such
exercise in an amount generally measured by the difference between the Exercise
Price for the Shares and the Fair Market Value of the Shares on the date of
exercise.  To the extent that Optionee was not entitled to exercise the Option
at the Termination Date, or if Optionee does not exercise such Option to the
extent so entitled within the time specified in this Section 6(b), the Option
shall terminate.

     7.  Death of Optionee.  In the event of the death of Optionee (a) during
         -----------------
the Term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Status as an Employee or Consultant since the date of
grant of the Option, or (b) within 30 days after Optionee's Termination Date,
the Option may be exercised at any time within six months following the date of
death (but in no event later than the Expiration Date set forth in the Notice of
Stock Option Grant), by Optionee's estate or by a person who acquired the right
to exercise the Option by bequest or inheritance, but only to the extent of the
right to exercise that had accrued at the Termination Date.

     8.  Non-Transferability of Option.  Except as otherwise provided in this
         -----------------------------
Section 8, this Option may not be transferred in any manner otherwise than by
will or by the laws of descent or distribution and may be exercised during the
lifetime of Optionee only by him or her.  However, Optionee, with the approval
of the Administrator, may transfer the Option to or for the benefit of one or
more members of Optionee's Immediate Family (as defined below), including,
without limitation, to a trust for the benefit of one or more members of
Optionee's Immediate Family or to a partnership or limited liability company
composed of one or more members of Optionee's Immediate Family, and subject to
such limits as the Administrator may establish.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and permitted
transferees of Optionee.  No transfer for consideration shall be permitted
except to a partnership or limited liability company composed of one or more
members of Optionee's Immediate Family.

     The foregoing right to transfer the Option shall apply to the right to
consent to amendments to this Agreement and, in the discretion of the
Administrator, shall also apply to the right to transfer ancillary rights
associated with the Option.  The term "Immediate Family" shall
<PAGE>

mean Optionee's spouse or former spouse, parents, children, stepchildren,
adoptive relationships, sisters, brothers, grandchildren, nieces, nephews,
mother-in-law, father-in-law, sons-in-law, daughters-in-law, brothers-in-law or
sisters-in-law (and, for this purpose, shall also include Optionee). Optionee
acknowledges and agrees that Optionee shall be responsible for payment of any
applicable income and employment tax withholdings imposed upon the transfer
and/or subsequent exercise of a transferred Option, and such transfer and the
transferee's right to receive the shares subject to this Option upon exercise
thereof is conditioned on satisfaction of such withholding taxes as the Company
determines may be due.

     9.  Term of Option.  This Option may be exercised only within the Term set
         --------------
forth in the Notice of Stock Option Grant, subject to the limitations set forth
in Section 7 of the Plan.

     10.  Tax Consequences.  Set forth below is a brief summary as of the date
          ----------------
of this Option of certain of the federal and California tax consequences of
exercise of this Option and disposition of the Shares under the laws in effect
as of the Date of Grant.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX
LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

          (a) Exercise of Incentive Stock Option.  If this Option qualifies as
              ----------------------------------
an Incentive Stock Option, there will be no regular federal or California income
tax liability upon the exercise of the Option, although the excess, if any, of
the Fair Market Value of the Shares on the date of exercise over the Exercise
Price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject Optionee to the alternative minimum tax in
the year of exercise.

          (b) Exercise of Nonstatutory Stock Option.  If this Option does not
              -------------------------------------
qualify as an Incentive Stock Option, there may be a regular federal income tax
liability and a California income tax liability upon the exercise of the Option.
Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the Fair Market Value
of the Shares on the date of exercise over the Exercise Price.  If Optionee is
an employee, the Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

          (c) Disposition of Shares.  In the case of a Nonstatutory Stock
              ---------------------
Option, if Shares are held for at least one year, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
and California income tax purposes.  In the case of an Incentive Stock Option,
if Shares transferred pursuant to the Option are held for at least one year
after exercise and are disposed of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal and California income tax purposes.  In either case,
the long-term capital gain will be taxed for federal income tax and alternative
minimum tax purposes at a maximum rate of 20% if the Shares are held more than
one year after exercise.  If Shares purchased under an Incentive Stock Option
are disposed of within one year after exercise or within two years after the
Date of Grant, any gain realized on such disposition will be treated as
compensation income (taxable at ordinary income rates) to the
<PAGE>

extent of the difference between the Exercise Price and the lesser of (i) the
Fair Market Value of the Shares on the date of exercise, or (ii) the sale price
of the Shares.

          (d) Notice of Disqualifying Disposition of Incentive Stock Option
              -------------------------------------------------------------
Shares.  If the Option granted to Optionee herein is an Incentive Stock Option,
------
and if Optionee sells or otherwise disposes of any of the Shares acquired
pursuant to the Incentive Stock Option on or before the later of (i) the date
two years after the Date of Grant, or (ii) the date one year after the date of
exercise, Optionee shall immediately notify the Company in writing of such
disposition.  Optionee acknowledges and agrees that he or she may be subject to
income tax withholding by the Company on the compensation income recognized by
Optionee from the early disposition by payment in cash or out of the current
earnings paid to Optionee.

     11.  Withholding Tax Obligations.
          ---------------------------

          (a) General Withholding Obligations.  As a condition to the exercise
              -------------------------------
of Option granted hereunder, Optionee shall make such arrangements as the
Administrator may require for the satisfaction of any federal, state, local or
foreign withholding tax obligations that may arise in connection with the
exercise, receipt or vesting of the Option.  The Company shall not be required
to issue any Shares under the Plan until such obligations are satisfied.
Optionee understands that, upon exercising a Nonstatutory Stock Option, he or
she will recognize income for tax purposes in an amount equal to the excess of
the then Fair Market Value of the Shares over the Exercise Price.  If Optionee
is an employee, the Company will be required to withhold from Optionee's
compensation, or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income.
Additionally, Optionee may at some point be required to satisfy tax withholding
obligations with respect to the disqualifying disposition of an Incentive Stock
Option. Optionee shall satisfy his or her tax withholding obligation arising
upon the exercise of this Option by one or some combination of the following
methods:  (i) by cash or check payment, (ii) out of Optionee's current
compensation, (iii) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares which (A) in the case of Shares previously
acquired from the Company, have been owned by Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value determined as of the
applicable Tax Date (as defined in Section 11(c) below) on the date of surrender
equal to the amount required to be withheld, or (iv) by electing to have the
Company withhold from the Shares to be issued upon exercise of the Option that
number of Shares having a Fair Market Value determined as of the applicable Tax
Date equal to the amount required to be withheld.

          (b) Stock Withholding to Satisfy Withholding Tax Obligations.  In the
              --------------------------------------------------------
event the Administrator allows Optionee to satisfy his or her tax withholding
obligations as provided in Section 11(a)(iii) or (iv) above, such satisfaction
must comply with the requirements of this Section (11)(b) and all Applicable
Laws.  All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

              (i)  the election must be made on or prior to the applicable Tax
Date (as defined in Section 11(c) below);
<PAGE>

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

           (iii) all elections shall be subject to the consent or
disapproval of the Administrator.

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

          (c) Definitions.  For purposes of this Section 11, the Fair Market
              -----------
Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined under the applicable laws (the
"Tax Date").
 --------

     12.  Market Standoff Agreement.  In connection with the initial public
          -------------------------
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Optionee agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any securities of the Company (other
than those included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed 180 days) from the effective date of such registration as may be
requested by the Company or such managing underwriters and to execute an
agreement reflecting the foregoing as may be requested by the underwriters at
the time of the Company's initial public offering.

                            [Signature Page Follows]

     This Agreement may be executed in two or more counterparts, each of which
shall be deemed an original and all of which together shall constitute one
document.

            EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT
            -------------------------------------------------------

     This Agreement ("Agreement") is made as of ______________, by and between
                      ---------
HealthCentral.com, a California corporation (the "Company"), and _________
                                                  -------
("Purchaser").  To the extent any capitalized terms used in this Agreement are
-----------
not defined, they shall have the meaning ascribed to them in the 1998 Stock
Plan.

     1.  Exercise of Option.  Subject to the terms and conditions hereof,
         ------------------
Purchaser hereby elects to exercise his or her option to purchase __________

______________, (the "Option Agreement").  The purchase price for the Shares
                      ----------------
shall be $______________ per Share for a total purchase price of
$_______________.  The term "Shares" refers to the purchased Shares and all
                             ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

     2.  Time and Place of Exercise. The purchase and sale of the Shares under
         --------------------------
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement.  On such date, the Company

exercise price therefor by Purchaser by (a) check made payable to the Company,
(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, or (d) a combination of the foregoing.

     3.  Limitations on Transfer.  In addition to any other limitation on

transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares except in compliance with the
provisions below and applicable securities laws.

          (a) Right of First Refusal.  Before any Shares held by Purchaser or
              ----------------------
any transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
-------
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(a) (the "Right of First Refusal").
                   ----------------------

              (i) Notice of Proposed Transfer.  The Holder of the Shares shall
                  ---------------------------
deliver to the Company a written notice (the "Notice") stating:  (i) the
                                              ------
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the
name of each proposed purchaser
<PAGE>

or other transferee ("Proposed Transferee"); (iii) the number of Shares to be
                      -------------------
transferred to each Proposed Transferee; and (iv) the terms and conditions of
each proposed sale or transfer. The Holder shall offer the Shares at the same
price (the "Offered Price") and upon the same terms (or terms as similar as
            -------------
reasonably possible) to the Company or its assignee(s).

          (ii)  Exercise of Right of First Refusal.  At any time within 30 days
                ----------------------------------
after receipt of the Notice, the Company and/or its assignee(s) may, by giving
written notice to the Holder, elect to purchase all, but not less than all, of
the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection
(iii) below.

         (iii)  Purchase Price.  The purchase price ("Purchase Price") for the
                --------------                        --------------
Shares purchased by the Company or its assignee(s) under this Section 3(a) shall
be the Offered Price.  If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

          (iv)  Payment.  Payment of the Purchase Price shall be made, at the
                -------
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

           (v)  Holder's Right to Transfer. If all of the Shares proposed in the
                --------------------------
Notice to be transferred to a given Proposed Transferee are not purchased by the
Company and/or its assignee(s) as provided in this Section 3(a), then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within 60 days after the date of the Notice and provided further
that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

           (vi) Exception for Certain Family Transfers. Anything to the contrary
                --------------------------------------
contained in this Section 3(a) notwithstanding, the transfer of any or all of
the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family (as defined below) or a trust for the
benefit of Purchaser's Immediate Family shall be exempt from the provisions of
this Section 3(a). "Immediate Family" as used herein shall mean spouse, lineal
                    ----------------
descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section, and there shall be no further
transfer of such Shares except in accordance with the terms of this Section 3.

          (b)  Involuntary Transfer.
               --------------------

               (i) Company's Right to Purchase upon Involuntary Transfer. In the
                   -----------------------------------------------------
event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including divorce or death, but
excluding, in the event of death, a transfer to Immediate Family as set forth in
Section 3(a)(vi) above) of all or a portion of the Shares by the record holder
thereof, the Company shall have the right to purchase all of the Shares
transferred at the greater of the purchase price paid by Purchaser pursuant to
this Agreement or the Fair Market Value of the Shares on the date of transfer.
Upon such a transfer, the person acquiring the Shares shall promptly notify the
Secretary of the Company of such transfer. The right to purchase such Shares
shall be provided to the Company for a period of 30 days following receipt by
the Company of written notice by the person acquiring the Shares.

              (ii) Price for Involuntary Transfer. With respect to any stock to
                   ------------------------------
be transferred pursuant to Section 3(b)(i), the price per Share shall be a price
set by the Board of Directors of the Company that will reflect the current value
of the stock in terms of present earnings and future prospects of the Company.
The Company shall notify Purchaser or his or her executor of the price so
determined within 30 days after receipt by it of written notice of the transfer
or proposed transfer of Shares. However, if the Purchaser does not agree with
the valuation as determined by the Board of Directors of the Company, the
Purchaser shall be entitled to have the valuation determined by an independent
appraiser to be mutually agreed upon by the Company and the Purchaser and whose
fees shall be borne equally by the Company and the Purchaser.

          (c) Assignment.  The right of the Company to purchase any part of the
              ----------
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations.

          (d) Restrictions Binding on Transferees.  All transferees of Shares or
              -----------------------------------
any interest therein will receive and hold such Shares or interest subject to
the provisions of this Agreement.  Any sale or transfer of the Shares shall be
void unless the provisions of this Agreement are satisfied.

          (e) Termination of Rights.  The Right of First Refusal and the
              ---------------------
Company's right to repurchase the Shares in the event of an involuntary transfer
pursuant to Section 3(b) above shall terminate upon the first sale of Common
Stock of the Company to the general public pursuant to a registration statement
filed with and declared effective by the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Securities Act").
                                                   --------------

          (f) Market Standoff Agreement.  In connection with the initial public
              -------------------------
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any securities of the Company (other
than those included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such

                                      10
<PAGE>

period of time (not to exceed 180 days) from the effective date of such
registration as may be requested by the Company or such managing underwriters
and to execute an agreement reflecting the foregoing as may be requested by the
underwriters at the time of the Company's initial public offering.

     4.  Investment and Taxation Representations.  In connection with the
         ---------------------------------------
purchase of the Shares, Purchaser represents to the Company the following:

          (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Shares.  Purchaser is
purchasing the Shares for investment for his or her own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act.

          (b) Purchaser understands that the Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

          (c) Purchaser understands that the Shares are "restricted securities"
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, Purchaser must hold the Shares indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available.  Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale.  Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

          (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

     5.  Restrictive Legends and Stop-Transfer Orders.
         --------------------------------------------

          (a) Legends.  The certificate or certificates representing the Shares
              -------
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

               (i)  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                    REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
                    ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
                    CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF.



                                      11
<PAGE>

                    NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN
                    EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN
                    OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY
                    THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES
                    ACT OF 1933.

               (ii) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
                    TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
                    AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF
                    WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Refusal to Transfer.  The Company shall not be required (i) to

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


     1.  Grant of Option.  HealthCentral.com, a California corporation (the
         ---------------
"Company"), hereby grants to _________ ("Optionee"), an option (the "Option") to
-------                                  --------                    ------
purchase a total number of shares of Common Stock (the "Shares") set forth in
                                                        ------
the Notice of Stock Option Grant, at the exercise price per share set forth in
the Notice of Stock Option Grant (the "Exercise Price") subject to the terms,
                                       --------------
definitions and provisions of the HealthCentral.com 1998 Stock Plan (the "Plan")
                                                                          ----
adopted by the Company, which is incorporated herein by reference.  Unless
otherwise defined herein, the terms defined in the Plan shall have the same
defined meanings in this Option.

     If designated an Incentive Stock Option, this Option is intended to qualify
as an Incentive Stock Option as defined in Section 422 of the Code.

     2.  Exercise of Option.  This Option shall be exercisable during its Term
         ------------------
in accordance with the Vesting Schedule set out in the Notice of Stock Option
Grant and with the provisions of Section 9 of the Plan as follows:

          (a)  Right to Exercise.
               -----------------

               (i) This Option may not be exercised for a fraction of a share.

              (ii) In the event of Optionee's death, disability or other
termination of employment, the exercisability of the Option is governed by
Sections 5, 6 and 7 below, subject to the limitation contained in Section
2(a)(i).

             (iii) In no event may this Option be exercised after the Expiration
Date of this Option as set forth in the Notice of Stock Option Grant.

          (b) Method of Exercise.  This Option shall be exercisable by execution
              ------------------
and delivery of the Exercise Notice and Restricted Stock Purchase Agreement
attached hereto as Exhibit A (the "Exercise Agreement") or of any other form of
                   ---------       ------------------
written notice approved for such purpose by the Company which shall state the
election to exercise the Option, the number of Shares in respect of which the
Option is being exercised, and such other representations and agreements as to
the holder's investment intent with respect to such shares of Common Stock as
may be required by the Company pursuant to the provisions of the Plan.  Such
written notice shall be signed by Optionee and shall be delivered in person or
by certified mail to the Secretary of the Company.  The written notice shall be
accompanied by payment of the Exercise Price.  This Option shall be deemed to be
exercised upon receipt by the Company of such written notice accompanied by the
Exercise Price.
<PAGE>

     No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of
applicable law and the requirements of any stock exchange upon which the Shares
may then be listed.  Assuming such compliance, for income tax purposes the
Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

      3.  Method of Payment.  Payment of the Exercise Price shall be by any of
          -----------------
the following, or a combination thereof, at the election of Optionee:

          (a)  cash or check;

          (b) cancellation of outstanding indebtedness;

          (c) surrender of other shares of Common Stock of the Company which (i)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by Optionee for more than six months on the date of surrender,
and (ii) have a Fair Market Value on the date of surrender equal to the Exercise
Price of the Shares as to which the Option is being exercised; or

          (d) if there is a public market for the Shares and they are registered
under the Exchange Act, delivery of a properly executed exercise notice together
with irrevocable instructions to a broker to deliver promptly to the Company the
amount of sale or loan proceeds required to pay the Exercise Price.

      4.  Restrictions on Exercise.  This Option may not be exercised until such
          ------------------------
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

      5.  Termination of Relationship. In the event of termination of Optionee's
          ---------------------------
Continuous Status as an Employee or Consultant, Optionee may, to the extent
otherwise so entitled at the date of such termination (the "Termination Date"),
                                                            ----------------
exercise this Option during the Termination Period set forth in the Notice of
Stock Option Grant. To the extent that Optionee was not entitled to exercise
this Option at such Termination Date, or if Optionee does not exercise this
Option within the Termination Period, the Option shall terminate.

      6.  Disability of Optionee.
          ----------------------

          (a) Notwithstanding the provisions of Section 5 above, in the event of
termination of Optionee's Continuous Status as an Employee or Consultant as a
result of Optionee's total and permanent disability (as defined in Section
22(e)(3) of the Code), Optionee may, but only within twelve months from the
Termination Date (but in no event later than the Expiration Date set forth in
the Notice of Stock Option Grant), exercise this Option to the extent
<PAGE>

Optionee was entitled to exercise it as of such Termination Date. To the extent
that Optionee was not entitled to exercise the Option as of the Termination
Date, or if Optionee does not exercise such Option (to the extent so entitled)
within the time specified in this Section 6(a), the Option shall terminate.

          (b) Notwithstanding the provisions of Section 5 above, in the event of
termination of Optionee's consulting relationship or Continuous Status as an
Employee as a result of disability not constituting a total and permanent
disability (as set forth in Section 22(e)(3) of the Code), Optionee may, but
only within six months from the Termination Date (but in no event later than the
Expiration Date set forth in the Notice of Stock Option Grant), exercise the
Option to the extent Optionee was entitled to exercise it as of such Termination
Date; provided, however, that if this is an Incentive Stock Option and Optionee
fails to exercise this Incentive Stock Option within three months from the
Termination Date, this Option will cease to qualify as an Incentive Stock Option
(as defined in Section 422 of the Code) and Optionee will be treated for federal
income tax purposes as having received ordinary income at the time of such
exercise in an amount generally measured by the difference between the Exercise
Price for the Shares and the Fair Market Value of the Shares on the date of
exercise.  To the extent that Optionee was not entitled to exercise the Option
at the Termination Date, or if Optionee does not exercise such Option to the
extent so entitled within the time specified in this Section 6(b), the Option
shall terminate.

     7.  Death of Optionee.  In the event of the death of Optionee (a) during
         -----------------
the Term of this Option and while an Employee or Consultant of the Company and
having been in Continuous Status as an Employee or Consultant since the date of
grant of the Option, or (b) within 30 days after Optionee's Termination Date,
the Option may be exercised at any time within six months following the date of
death (but in no event later than the Expiration Date set forth in the Notice of
Stock Option Grant), by Optionee's estate or by a person who acquired the right
to exercise the Option by bequest or inheritance, but only to the extent of the
right to exercise that had accrued at the Termination Date.

     8.  Non-Transferability of Option.  This Option may not be transferred in
         -----------------------------
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by him or her.  The terms
of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of Optionee.

     9.  Term of Option.  This Option may be exercised only within the Term set
         --------------
forth in the Notice of Stock Option Grant, subject to the limitations set forth
in Section 7 of the Plan.

     10.  Tax Consequences.  Set forth below is a brief summary as of the date
          ----------------
of this Option of certain of the federal and California tax consequences of
exercise of this Option and disposition of the Shares under the laws in effect
as of the Date of Grant.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX
LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.
<PAGE>

          (a) Exercise of Incentive Stock Option.  If this Option qualifies as
              ----------------------------------
an Incentive Stock Option, there will be no regular federal or California income
tax liability upon the exercise of the Option, although the excess, if any, of
the Fair Market Value of the Shares on the date of exercise over the Exercise
Price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject Optionee to the alternative minimum tax in
the year of exercise.

          (b) Exercise of Nonstatutory Stock Option.  If this Option does not
              -------------------------------------
qualify as an Incentive Stock Option, there may be a regular federal income tax
liability and a California income tax liability upon the exercise of the Option.
Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the Fair Market Value
of the Shares on the date of exercise over the Exercise Price.  If Optionee is
an employee, the Company will be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

          (c) Disposition of Shares.  In the case of a Nonstatutory Stock
              ---------------------
Option, if Shares are held for at least one year, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
and California income tax purposes.  In the case of an Incentive Stock Option,
if Shares transferred pursuant to the Option are held for at least one year
after exercise and are disposed of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal and California income tax purposes.  In either case,
the long-term capital gain will be taxed for federal income tax and alternative
minimum tax purposes at a maximum rate of 20% if the Shares are held more than
one year after exercise.  If Shares purchased under an Incentive Stock Option
are disposed of within one year after exercise or within two years after the
Date of Grant, any gain realized on such disposition will be treated as
compensation income (taxable at ordinary income rates) to the extent of the
difference between the Exercise Price and the lesser of (i) the Fair Market
Value of the Shares on the date of exercise, or (ii) the sale price of the
Shares.

          (d) Notice of Disqualifying Disposition of Incentive Stock Option
              -------------------------------------------------------------
Shares.  If the Option granted to Optionee herein is an Incentive Stock Option,
------
and if Optionee sells or otherwise disposes of any of the Shares acquired
pursuant to the Incentive Stock Option on or before the later of (i) the date
two years after the Date of Grant, or (ii) the date one year after the date of
exercise, Optionee shall immediately notify the Company in writing of such
disposition.  Optionee acknowledges and agrees that he or she may be subject to
income tax withholding by the Company on the compensation income recognized by
Optionee from the early disposition by payment in cash or out of the current
earnings paid to Optionee.

     11.  Withholding Tax Obligations.
          ---------------------------

          (a) General Withholding Obligations.  As a condition to the exercise
              -------------------------------
of Option granted hereunder, Optionee shall make such arrangements as the
Administrator may require for the satisfaction of any federal, state, local or
foreign withholding tax obligations that may arise in connection with the
exercise, receipt or vesting of the Option.  The Company shall not be required
to issue any Shares under the Plan until such obligations are satisfied.
Optionee
<PAGE>

understands that, upon exercising a Nonstatutory Stock Option, he or
she will recognize income for tax purposes in an amount equal to the excess of
the then Fair Market Value of the Shares over the Exercise Price.  If Optionee
is an employee, the Company will be required to withhold from Optionee's
compensation, or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income.
Additionally, Optionee may at some point be required to satisfy tax withholding
obligations with respect to the disqualifying disposition of an Incentive Stock
Option. Optionee shall satisfy his or her tax withholding obligation arising
upon the exercise of this Option by one or some combination of the following
methods:  (i) by cash or check payment, (ii) out of Optionee's current
compensation, (iii) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares which (A) in the case of Shares previously
acquired from the Company, have been owned by Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value determined as of the
applicable Tax Date (as defined in Section 11(c) below) on the date of surrender
equal to the amount required to be withheld, or (iv) by electing to have the
Company withhold from the Shares to be issued upon exercise of the Option that
number of Shares having a Fair Market Value determined as of the applicable Tax
Date equal to the amount required to be withheld.

          (b) Stock Withholding to Satisfy Withholding Tax Obligations.  In the
              --------------------------------------------------------
event the Administrator allows Optionee to satisfy his or her tax withholding
obligations as provided in Section 11(a)(iii) or (iv) above, such satisfaction
must comply with the requirements of this Section (11)(b) and all applicable
laws.  All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

               (i) the election must be made on or prior to the applicable Tax
Date (as defined in Section 11(c) below);

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

               (iii)  all elections shall be subject to the consent or

                                1998 STOCK PLAN

            EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT
            -------------------------------------------------------

     This Agreement ("Agreement") is made as of ______________, by and between
                      ---------
HealthCentral.com, a California corporation (the "Company"), and _________
                                                  -------
("Purchaser").  To the extent any capitalized terms used in this Agreement are
-----------
not defined, they shall have the meaning ascribed to them in the 1998 Stock
Plan.

     1.  Exercise of Option.  Subject to the terms and conditions hereof,
         ------------------
Purchaser hereby elects to exercise his or her option to purchase __________
shares of the Common Stock (the "Shares") of the Company under and pursuant to
                                 ------
the Company's 1998 Stock Plan (the "Plan") and the Stock Option Agreement dated
                                    ----
______________, (the "Option Agreement").  The purchase price for the Shares
                      ----------------
shall be $______________ per Share for a total purchase price of
$_______________.  The term "Shares" refers to the purchased Shares and all
                             ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

     2.  Time and Place of Exercise. The purchase and sale of the Shares under
         --------------------------
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement.  On such date, the Company
will deliver to Purchaser a certificate representing the Shares to be purchased
by Purchaser (which shall be issued in Purchaser's name) against payment of the
exercise price therefor by Purchaser by (a) check made payable to the Company,
(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, or (d) a combination of the foregoing.

     3.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares except in compliance with the
provisions below and applicable securities laws.

         (a) Right of First Refusal.  Before any Shares held by Purchaser or
             ----------------------
any transferee of Purchaser (either being sometimes referred to herein as the

"Holder") may be sold or otherwise transferred (including transfer by gift or
-------
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(a) (the "Right of First Refusal").
                   ----------------------

             (i) Notice of Proposed Transfer.  The Holder of the Shares shall
                 ---------------------------
deliver to the Company a written notice (the "Notice") stating:  (i) the
                                              ------
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the
name of each proposed purchaser
<PAGE>

or other transferee ("Proposed Transferee"); (iii) the number of Shares to be
                      -------------------
transferred to each Proposed Transferee; and (iv) the terms and conditions of
each proposed sale or transfer. The Holder shall offer the Shares at the same
price (the "Offered Price") and upon the same terms (or terms as similar as
            -------------
reasonably possible) to the Company or its assignee(s).

          (ii) Exercise of Right of First Refusal.  At any time within 30 days
               ----------------------------------
after receipt of the Notice, the Company and/or its assignee(s) may, by giving
written notice to the Holder, elect to purchase all, but not less than all, of
the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection
(iii) below.

         (iii) Purchase Price.  The purchase price ("Purchase Price") for the
               --------------                        --------------
Shares purchased by the Company or its assignee(s) under this Section 3(a) shall
be the Offered Price.  If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

          (iv) Payment.  Payment of the Purchase Price shall be made, at the
               -------
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

           (v) Holder's Right to Transfer.  If all of the Shares proposed in the
               --------------------------
Notice to be transferred to a given Proposed Transferee are not purchased by the
Company and/or its assignee(s) as provided in this Section 3(a), then the Holder
may sell or otherwise transfer such Shares to that Proposed Transferee at the
Offered Price or at a higher price, provided that such sale or other transfer is
consummated within 60 days after the date of the Notice and provided further
that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee.  If the Shares described in the Notice are
not transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

          (vi) Exception for Certain Family Transfers.  Anything to the contrary
               --------------------------------------
contained in this Section 3(a) notwithstanding, the transfer of any or all of
the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family (as defined below) or a trust for the
benefit of Purchaser's Immediate Family shall be exempt from the provisions of
this Section 3(a).  "Immediate Family" as used herein shall mean spouse, lineal
                     ----------------
descendant or antecedent, father, mother, brother or sister.  In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section, and there shall be no further
transfer of such Shares except in accordance with the terms of this Section 3.

                                      -9-
<PAGE>

      (b)  Involuntary Transfer.
           --------------------

          (i) Company's Right to Purchase upon Involuntary Transfer.  In the
              -----------------------------------------------------
event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including divorce or death, but
excluding, in the event of death, a transfer to Immediate Family as set forth in
Section 3(a)(vi) above) of all or a portion of the Shares by the record holder
thereof, the Company shall have the right to purchase all of the Shares
transferred at the greater of the purchase price paid by Purchaser pursuant to
this Agreement or the Fair Market Value of the Shares on the date of transfer.
Upon such a transfer, the person acquiring the Shares shall promptly notify the
Secretary of the Company of such transfer.  The right to purchase such Shares
shall be provided to the Company for a period of 30 days following receipt by
the Company of written notice by the person acquiring the Shares.

          (ii) Price for Involuntary Transfer.  With respect to any stock to be
               ------------------------------
transferred pursuant to Section 3(b)(i), the price per Share shall be a price
set by the Board of Directors of the Company that will reflect the current value
of the stock in terms of present earnings and future prospects of the Company.
The Company shall notify Purchaser or his or her executor of the price so
determined within 30 days after receipt by it of written notice of the transfer
or proposed transfer of Shares.  However, if the Purchaser does not agree with
the valuation as determined by the Board of Directors of the Company, the
Purchaser shall be entitled to have the valuation determined by an independent
appraiser to be mutually agreed upon by the Company and the Purchaser and whose
fees shall be borne equally by the Company and the Purchaser.

      (c) Assignment.  The right of the Company to purchase any part of the
          ----------
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations.

      (d) Restrictions Binding on Transferees.  All transferees of Shares or
          -----------------------------------
any interest therein will receive and hold such Shares or interest subject to
the provisions of this Agreement.  Any sale or transfer of the Shares shall be
void unless the provisions of this Agreement are satisfied.

      (e) Termination of Rights.  The Right of First Refusal and the
          ---------------------
Company's right to repurchase the Shares in the event of an involuntary transfer
pursuant to Section 3(b) above shall terminate upon the first sale of Common
Stock of the Company to the general public pursuant to a registration statement
filed with and declared effective by the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Securities Act").
                                                   --------------

      (f) Market Standoff Agreement.  In connection with the initial public
          -------------------------
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any securities of the Company (other
than those included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such

                                     -10-
<PAGE>

period of time (not to exceed 180 days) from the effective date of such
registration as may be requested by the Company or such managing underwriters
and to execute an agreement reflecting the foregoing as may be requested by the
underwriters at the time of the Company's initial public offering.

     4.  Investment and Taxation Representations.  In connection with the
         ---------------------------------------
purchase of the Shares, Purchaser represents to the Company the following:

          (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Shares.  Purchaser is
purchasing the Shares for investment for his or her own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act.

          (b) Purchaser understands that the Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

          (c) Purchaser understands that the Shares are "restricted securities"
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, Purchaser must hold the Shares indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available.  Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale.  Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

          (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

     5.  Restrictive Legends and Stop-Transfer Orders.
         --------------------------------------------

          (a) Legends.  The certificate or certificates representing the Shares
              -------
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

               (i)  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                    REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
                    ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
                    CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF.


                                     -11-
<PAGE>

                    NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN
                    EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN
                    OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY
                    THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES
                    ACT OF 1933.

               (ii) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
                    TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
                    AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF
                    WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Refusal to Transfer.  The Company shall not be required (i) to
              -------------------
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

          (d) Removal of Legend.  When all of the following events have
              -----------------
occurred, the Shares then held by Purchaser will no longer be subject to the
legend referred to in Section 5(a)(ii):  (i) the termination of the Right of
First Refusal; and (ii) the expiration or termination of the market standoff
provisions of Section 3(f) (and of any agreement entered pursuant to Section
3(f)).  After such time, and upon Purchaser's request, a new certificate or
certificates representing the Shares not repurchased shall be issued without the
legend referred to in Section 5(a)(ii), and delivered to Purchaser.

     6.  No Employment Rights.  Nothing in this Agreement shall affect in any
         --------------------
manner whatsoever the right or power of the Company, or a Parent or Subsidiary
of the Company, to terminate Purchaser's employment or consulting relationship,
for any reason, with or without cause.

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

          (a) Governing Law.  This Agreement and all acts and transactions
              -------------
pursuant hereto and the rights and obligations of the parties hereto shall be

California, without giving effect to principles of conflicts of law.

forth the entire agreement and understanding of the parties relating to the
subject matter

amendment to this Agreement, nor any waiver of any rights under this Agreement,
shall be effective unless in writing signed by the parties to this Agreement.

          (c) Severability.  If one or more provisions of this Agreement are
              ------------
held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith.  In the event that the parties cannot reach a
mutually agreeable and enforceable replacement for such provision, then (i) such
provision shall be excluded from this Agreement, (ii) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (iii)
the balance of the Agreement shall be enforceable in accordance with its terms.

          (d) Construction.  This Agreement is the result of negotiations
              ------------
between and has been reviewed by each of the parties hereto and their respective

modified by written notice.

          (f) Counterparts.  This Agreement may be executed in two or more
              ------------
counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.

          (g) Successors and Assigns.  The rights and benefits of this Agreement
              ----------------------
shall inure to the benefit of, and be enforceable by the Company's successors
and assigns.  The rights and obligations of Purchaser under this Agreement may
only be assigned with the prior written consent of the Company.
