                               HealthCentral.com

Our Business

   Our company provides online healthcare content and 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 who has a daily syndicated radio program that is
    broadcast on over 300 radio stations, and a syndicated television report
    broadcast in over 50 television markets, reaching a combined 20 million
    individuals per week. In August 1999, according to an audit completed by
    Nielsen I/PRO, www.healthcentral.com attracted five million page views,
    and according to Double Click 599,400 unique users.

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

   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. In the fourth quarter of 1999, we intend
to launch www.peoplespharmacy.healthcentral.com, featuring pharmacy-related
content provided exclusively by the authors of The People's Pharmacy, a
newspaper column published three times a week in over 100 markets. We also have
an agreement with MediaLinx, a Canadian portal, to launch a co-branded health
channel focusing on Canadian health content, which we intend to launch in the
fourth quarter of 1999.

   In addition, we act as an application service provider for healthcare
institutions by designing, hosting and maintaining private label websites for
them. 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 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 31.6% of surveyed Internet users shopped for
healthcare 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, sponsorships
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. 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
    through our relationships with established medical professionals in
    traditional media such as Dr. Dean Edell and Joe and Teresa Graedon,
    through our portal deals with AltaVista, America Online and MediaLinx and
    through television, radio and newspapers;

  . cultivate our multiple revenue streams of sponsorship and advertising
    fees principally from our flagship HealthCentral.com website, e-commerce
    revenue from ePills.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 ePills.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 and
    PeoplesPharmacy.HealthCentral.com;

  . leverage personalization features and interactive tools to increase
    users' return visits to our network;

  . 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.

   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 and www.epills.com, does not constitute part of
this prospectus.

                                  ePills Inc.

   In September 1999, we entered into an acquisition agreement with ePills

                                  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, but are not the only risks we face. 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 have a limited operating history, which makes it difficult for investors to
evaluate an investment in our common stock.

   We launched our HealthCentral.com network in November 1998, and our
ePills.com website was launched in September 1999. We therefore have a limited
operating history on which you can evaluate our business. We may not be able to
achieve revenue growth or profitability. 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;

  .  gain advertising and sponsorship revenue;

  .  implement a successful e-commerce strategy;

  .  maintain our current, and build new, strategic alliances with portals,
     physician 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 have a history of losses and expect our expenses to increase, and thus may
never become profitable.

   Since our inception, we have had very limited revenues and have incurred net
losses in each year. As of June 30, 1999, we had an accumulated deficit of
approximately $2.4 million. While we are unable to predict accurately our
future operating expenses, we currently expect these expenses to increase
substantially, as we, among other things:

  .  enter into third party alliances to expand our HealthCentral.com
     network;

  .  promote our brands;

  .  develop or acquire content;

  .  hire additional employees;

  .  increase our sales and marketing activities, including making
     substantial payments to advertising partners;

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

  .  offer product promotions.

   We expect our operating expenses to substantially exceed revenues for the
foreseeable future, and we may never become profitable.

                                       8
<PAGE>

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

 We must build our brands in a market dominated by better established
 competitors.

   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 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 need to build three separate brand names for each of HealthCentral.com,
 ePills.com and Windom Health, and this brand management strategy is expensive
 and difficult.

   We intend to build separate brands around our HealthCentral.com consumer
network, including our ePills.com online drug store, and our Windom Health
institutional Internet services. This brand management strategy is based on our
intention to separate e-commerce and institutional activities from the
provision of health information to consumers so that our commercial activities
do not impair perceptions of the trustworthiness of our content. This brand
management strategy may be more expensive and less effective than a strategy
based on one brand. If this strategy confuses consumers or if our e-commerce or
institutional Internet services taints the trustworthiness of our content in
consumers' minds, then our business could suffer.

   In addition, we intend to market our ePills.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 ePills.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, neither of which he
is paid for or contractually obligated to do. 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. If Dr. Edell started charging us a fee
for either of these activities, our expenses would increase.

   In addition, Premiere Radio Networks, the syndicator of Dr. Edell's radio
show, owns the exclusive rights to broadcast and redistribute Dr. Edell's radio
shows in all forms of media, including the Internet. Under his agreement with
Premiere Radio Networks, 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 and could harm our
business. Although we do maintain key person life insurance for Dr. Edell, his
role in providing unique content and marketing for the HealthCentral.com
network is sufficiently critical that the insurance would not adequately
protect us in the event of his loss. 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, e-
commerce transactions, institutional clientele and other sources of online
revenue, and the number of online participants in the healthcare market is
increasing at a rapid rate. In addition, traditional media and healthcare
providers compete for consumers' attention both through traditional means as
well as through new Internet initiatives.

 HealthCentral.com Website

   We currently compete directly for users, advertisers and content providers
with numerous Internet and non-Internet businesses, including:

  .  health-related online services or websites targeted at consumers;

  .  online and Internet portal companies;

  .  healthcare providers and payors, which offer healthcare information
     through the Internet; and

  .  other consumer affinity groups that offer healthcare-related content to
     special demographic groups.

See "Business--Competition--HealthCentral.com."

 ePills.com Online Drug Store

   Through ePills.com, we compete with online companies that sell
pharmaceuticals as well as over-the-counter drug and health, beauty and
personal care items, such as drugstore.com and planetRx, and pharmacy benefit
managers, or PBMs, that sell pharmaceuticals directly.

   We compete with traditional brick-and-mortar drug stores, including drug
store chains, discount drug stores, supermarkets, combination food and drug
stores, mass market retailers, independent drug stores and local merchants. See
"--We need to generate substantial revenues from our e-commerce business for
healthcare products, and yet this market is unproven and we have limited
experience in it--Consumers may reject the concept of an online drug store in
favor of a brick-and-mortar drug store." Many of these brick-and-mortar drug
stores are also beginning to offer online services. We also compete with
hospitals, HMOs and mail order prescription drug providers, all of whom are or
may begin offering products and services over the Internet.

   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
competitors forming alliances with each other. For instance, drugstore.com has
formed an alliance with RiteAid. In addition, PBMs and HMOs could form
alliances with our competitors that would prevent them from also entering into
relationships with us. For example, planetRx has formed a strategic alliance
with Express Scripts, Inc.

   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. Increased competition could result in price reductions, fewer customer
orders, reduced margins and loss of, or failure to build, market share, any of
which could harm our business. See "Business--Competition--ePills.com."


                                       10
<PAGE>

 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, 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, our product
mix is inappropriate for their needs, or that it would be more efficient and
desirable for them to independently develop and manage the process of
exchanging information with their consumers over the Internet. See "Business--
Competition--Institutional Internet Services."

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

 The healthcare e-commerce market is unproven.

   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. Our rate of
revenue growth could therefore be significantly less than that of other online
merchants.

 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 insurance carriers or
     pharmacy benefit managers;

  .  lack of consumer awareness of our online drug store;

  .  delivery time associated with Internet orders, as compared to the
     immediate receipt of products at a physical store;

  .  shipping charges, which do not apply to shopping at brick-and-mortar
     pharmacies;

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

  .  pricing that does not meet customer expectations of finding the lowest
     price on the Internet;

  .  additional steps and delays in ensuring insurance coverage for
     prescription products;

  .  customer concerns about the security of online transactions and the
     privacy of their personal health information;

  .  product damage from shipping or shipments of wrong or expired products
     from our fulfillment partners, resulting in a failure to establish
     customers' trust in buying pharmacy and other health products online;

  .  acute conditions that require immediate access to prescriptions;

  .  delays in responses to customer inquiries or in deliveries to customers;
     and

  .  difficulties in returning or exchanging orders.

                                       11

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

   ePills.com was only incorporated in January 1999 and only launched its
website in September 1999, and thus ePills.com has no experience to date in the
sale of healthcare products and services online. Prior to our acquisition of
ePills.com, we had no experience in the online sale of health products. If we
do not successfully develop our e-commerce operation, our business could fail.

We rely on Bergen Brunswig and Medi-Mail for fulfillment of our orders and
access to pharmacy benefit managers, and this relationship involves many risks.

   In July and September 1999, ePills.com entered into a series of agreements
with Bergen Brunswig and its Medi-Mail subsidiary. These agreements are central
to our e-commerce strategy, and they include various arrangements relating to
the fulfillment of orders placed on our ePills.com website for healthcare
products and access to the PlusCare Provider Network of pharmacy benefit
managers. Under these agreements, Bergen Brunswig will be our exclusive
fulfillment provider for health and beauty and over-the-counter products and
Medi-Mail will be our exclusive fulfillment provider for most prescription drug
orders. This type of arrangement is complex, and there are many important
details regarding pricing, revenue sharing and operational procedures which
ePills.com and Bergen Brunswig have not yet finalized. This arrangement will
thus require a great deal of effort to operate successfully, and there are many
risks related to these relationships, including some that we may not have
foreseen. 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 ePills.com's relationship with
Bergen Brunswig, customer perceptions, revenues and our ability to execute our
e-commerce strategy may be jeopardized.

   We expect that Medi-Mail will fill prescription orders placed on
ePills.com's website by mail, and that Bergen Brunswig will fulfill orders for
over-the-counter and health and beauty aid products placed through ePills.com
by mail. This fulfillment mechanism is complex and will require us to integrate
Bergen Brunswig's fulfillment systems with our web-based systems. Integrating
different information systems is technically difficult and may be delayed,
which could delay our receipt of revenues and diminish customer acceptance.

   ePills.com has an agreement with Bergen Brunswig regarding access to the
PlusCare Provider Network of over 70 pharmacy benefit managers. These PBMs
provide 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. 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. Furthermore, 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 four
months 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.

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 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

                                       12
<PAGE>

obligated to pay AltaVista $32.5 million and America Online $14.1 million over
the course of the next two years. The extent and timing of our capital
requirements will depend upon several factors, including:

  .  the rate of our sales and marketing spending;

  .  our ability to generate revenue from advertising, e-commerce and our
     institutional Internet services;

  .  our ability to increase traffic on our HealthCentral.com website;

  .  the cost of expanding our content offerings; and

  .  the cost of technology upgrades and systems integration related to our
     network infrastructure.

   The sale of additional equity or convertible debt securities could result in
additional 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. In either case, our ability to
fund our operations, take advantage of unanticipated opportunities, develop or
enhance editorial content or our e-commerce business, or otherwise respond to
competitive pressure would be significantly limited.

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.

   In September 1999 we entered into a three year agreement with AltaVista to
develop a co-branded health channel. The agreement calls for our payment of an
aggregate of $65.6 million in cash and stock issued at fair market value to
AltaVista over the three-year term in exchange for a minimum number of user
impressions on the co-branded health channel; 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. Our payment obligations to AltaVista are reduced if AltaVista fails to
meet its minimum impressions obligations. In addition, in August 1999,
ePills.com entered into a two year agreement with America Online under which
ePills.com will appear as an anchor tenant on the America Online Health Online
Pharmacy and receive a minimum number of advertising impressions in exchange
for payments of $14.1 million. These transactions are premised on the
assumption that the traffic we obtain from these arrangements will permit us to
increase awareness of our brand and generate revenues in excess of the payments
we make. However, even if AltaVista delivers the minimum 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 sufficient to justify our
expenses because users visiting our co-branded health channel may remain there
for a limited number of page views before they will be redirected to the
HealthCentral.com network. If we do not receive the revenues we currently
expect from these relationships, or if the AltaVista Health Channel or the
America Online HealthOnline Pharmacy Channel is unsuccessful in attracting
traffic to our websites or in enhancing our brands, our business will suffer.

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 that our insurance
may not cover. ePills.com will be the first point of contact for the consumer
in processing a prescription order. As the most visible participant in the
medication distribution chain, ePills.com may have more exposure to liability
claims.

   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 ePills.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 or may not have
provided all relevant information. We also plan to post product information on
our ePills.com website.

                                       13

Providing information on pharmaceutical and other products creates the
potential for claims to be made against us for negligence, personal injury,
wrongful death, product liability, malpractice, invasion of privacy or other
legal theories based on our product or service offerings. 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 ePills.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 ePills.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, whether through ePills.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 products we sell through e-
commerce.

   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.
As a result, any such claims, whether or not successful, could seriously damage
our reputation and our business.

The health information and health products we provide are subject to extensive
and changing governmental regulation.

   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 and over the counter drugs; and

  .  advertising of drugs and cosmetics.

   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."

Our strategy to provide unique healthcare content and drive traffic to our
HealthCentral.com network through cross-media exposure may not be successful.

   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

                                       14
<PAGE>

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 as a result of
early termination, it could delay market acceptance of the HealthCentral.com
network and/or disrupt end-user services until equivalent content, if any, can
be secured.

   Additionally, our ability to increase our own brand awareness and website
traffic from relationships with third party content providers is contingent
upon the status of these content providers as healthcare experts, the size of
their audiences and their willingness to promote our brands, all of which are
outside of our control.

We rely on relationships with other Internet companies to drive traffic and
build brand awareness.

   We have entered into agreements with other 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 or possible future agreements are short-term, non-exclusive or
may be terminated at the convenience of either party. If we are unable to
develop and maintain these relationships and generate sufficient traffic and
revenues from them, our business could suffer. In addition, those companies
that provide us with impressions or links to our network may never achieve
market acceptance or commercial success themselves, which could reduce our
revenues below our expectations and otherwise negatively impact the likelihood
of our success.

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 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.

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.

   The satisfactory performance, reliability and availability of the
HealthCentral.com network, including the ePills.com online drug store, is
critical to our reputation and our ability to attract and retain customers and
to maintain adequate customer service levels. System problems may include:

  .  unanticipated system disruptions;

  .  slower system response times;

  .  degradation in levels of service;

  .  impaired quality; and

  .  delays in reporting accurate information.

   Any of these systems problems could result in negative publicity and reduce
the attractiveness of our website to consumers and reduce our advertising, e-
commerce and institutional revenues. Any service lapses could cause our users
to instead use the online services of our competitors or revert to traditional
drug stores.

   Additionally, the satisfactory performance of the websites we build for our
institutional clients is critical to our business. If we fail to meet the
website performance standards in our contracts with our institutional clients,
they may terminate their agreements with us, or require that we refund part or
all of the license fees. Inadequate performance could also cause our renewal
rates of institutional licenses to significantly decrease below our
expectations, which would directly and significantly impact our business.

                                       15
<PAGE>

   From time to time, we have experienced temporary system interruptions for a
variety of reasons, including power failures, flaws in our software and greater
than expected site traffic. 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, and thus we
may not be able to exercise sufficient control to remedy the problem quickly or
at all.

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 on
the HealthCentral.com website, 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

and providers may determine that our solutions are too costly to implement or
unnecessary to manage their relationship 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. Our revenues could be adversely affected if we are unable to adapt to
new forms of Internet advertising. Moreover, filter software programs are now
available that limit or prevent advertising from being delivered to an Internet
user's computer. Widespread adoption of this software could adversely affect
the commercial viability of Internet advertising, 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. Advertising
and product claims of companies marketing or

                                       16
<PAGE>

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 for many reasons,
including:

  .  seasonal and cyclical patterns of spending by advertisers and sponsors;

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

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

  .  our ability to enhance our technology to accommodate any future growth
     in our operations or customers;

  .  changes in the growth rate of Internet usage;

  .  user traffic levels on HealthCentral.com; and

  .  costs related to potential acquisitions of technology or businesses.

   Our quarterly revenues and operating results will also be significantly
influenced by the success of our e-commerce activities. In addition to the
reasons specified above, revenues and expenses from selling health, personal
care, supplements, beauty, parenting and pharmacy products may fluctuate from
quarter to quarter due to a number of factors, including:

  .  demand for our products;

  .  the availability or timeliness of reimbursement from pharmacy benefit
     managers and insurance companies for prescription drugs;

  .  our ability to attract visitors to our website and convert those
     visitors into customers;

  .  the frequency of repeat purchases by customers;

  .  average order size;

  .  the mix of products sold;

  .  our ability, and that of our fulfillment partners, to ensure sufficient
     product supply;

  .  changes in our pricing policies or the pricing policies of our
     competitors; 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. Any shortfall in revenues relative to
our expectations could cause a significant decline in our quarterly operating
results.

We have recently experienced and are currently experiencing rapid growth in our
business, and our inability to manage this growth could harm our business.

   We have experienced and are currently experiencing a period of significant
growth. This growth has placed, and the future growth we anticipate in our
operations will continue to place, a significant strain on our resources. As a
result of the ePills.com acquisition, we have added over 13 new employees,
including managerial, technical and operations personnel, and we will need to
assimilate the operations of ePills.com into our operations. In order to manage
this growth effectively, we have to implement new transaction-processing,
operational and financial systems, procedures and controls, expand, train and
manage our employee base, and maintain close coordination among our technical,
accounting, finance, marketing, sales and editorial staffs. We also need to
devote significant management time and financial resources to website and
content development,

                                       17
<PAGE>

strategic relationships, technology infrastructure and finance and
administrative infrastructure. Our failure to successfully implement, improve
and integrate new systems and procedures, and otherwise manage our growth would
adversely affect our results of operations.

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
ePills.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 will be severely harmed. We
will need to hire additional personnel in virtually all operational areas,
including sales and marketing, production and research and development.
Competition for personnel throughout the Internet and healthcare industry is
intense. We may be unable to retain our key employees or attract, assimilate or
retain other highly qualified employees in the future. We have from time to
time in the past experienced, and we expect to continue to experience in the
future, difficulty in hiring and retaining highly skilled employees with
appropriate qualifications.

Lengthy sales cycles for our institutional solutions could adversely affect our
revenue growth.

   A key element of our institutional strategy is to market our solutions
directly to large healthcare organizations. We expect that the sales process
will be lengthy and will involve a significant technical evaluation and
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 large 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 and epills.com, as well as various other
related names. Domain names generally are regulated by Internet regulatory
bodies. The regulation of domain names in the United States and in foreign
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 or epills.com
domain name 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 brand name, 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. The domain names doctoredell.com and
dredell.com are currently registered in the name of, and operated by, a third
party, and the domain name epill.com is registered in the name of, and operated
by, e-pill LLC, a company in the business of developing and marking medication
reminder products. The URLs e-pills.com and epill.com are also owned by third
parties. Any confusion that may result from information on or related to these
websites either presently or in the future, or on any other websites with
domain names relating to our brands, could impair both our ability to
capitalize upon our brands and our marketing strategy.

                                       18
<PAGE>

We may not achieve the expected benefits of the acquisition of ePills.com, and
the integration of ePills.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 ePills.com personnel and
operations or fund or accomplish the execution of this e-commerce business
plan. The integration of ePills.com into our business may strain our existing
technology and operations systems as we attempt to assimilate ePills.com into
our existing operations. In addition, key ePills.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 two acquisitions, Windom Health and ePills.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 ePills.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. We
use encryption and authentication technology licensed from third parties to
provide security and authentication for the secure transmission of confidential
information, such as buyer credit card numbers and non-anonymous patient
medical information. In addition, we maintain industry standard security
measures such as firewalls, video surveillance and secure facilities. Despite
the implementation of these security measures, our infrastructure may be
vulnerable to breaches from physical break-ins, computer viruses, programming
errors or attacks by third parties. Our systems are also vulnerable to damage
or interruption from fire, flood, power loss, telecommunications failure,
earthquakes and similar events. We do not have full redundancy for all of our
computer and telecommunications facilities and do not maintain a back-up data
facility. Any breach of security or 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 may incur additional expenses if new regulations
regarding the use of personal information are adopted or if any regulator
chooses to investigate our privacy practices.

Any failure or inability to protect our intellectual property rights could
adversely affect our ability to establish our brands.

   Our success depends significantly on our ability to protect our proprietary
rights in our content, technology, products and services. We also rely on a
variety of technologies that are licensed from third parties, including our
database and Internet server software, which is used in the HealthCentral.com
network to perform key functions. These third-party licenses may not be
available to us on commercially reasonable terms in the future. If we are not
adequately protected, 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

                                       19
<PAGE>

combination of copyright and trademark laws, trade secrets, confidentiality
provisions and other contractual provisions to protect our proprietary rights,
but these legal means afford only limited protection. See "Business--
Intellectual Property."

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.

   We may not be able to operate under the tradename "ePills.com."

   We are aware that another company has filed an "intent to use" application
for the trademark "E-Pill." 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 content and services relating to a medical condition they may
have or may distribute our content to others, third parties may sue us for,
among other things, defamation, negligence, intellectual property infringement,
personal injury or other causes of action based on the nature and content of
materials that we publish or distribute. 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.

   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 our material systems, our vendors' material systems or the
Internet to be able to distinguish between twentieth century dates and twenty-
first century dates could harm our business. 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.

   We are in the final stages of assessing the year 2000 readiness of the
software, computer technology and other services that we use that may not be
year 2000 compliant. Although we have attempted to isolate our systems to
minimize the expected period of downtime for our websites, in the event of
systems difficulties, we have not yet developed a contingency plan to address
situations that may result if we or our vendors are unable to achieve year 2000
compliance. We understand that Medi-Mail, our pharmacy fulfillment provider, is
not currently year 2000 compliant, but expects to be by November 1, 1999. If
Medi-Mail has year 2000 problems, we could face delays in processing and
fulfillment of prescription drug orders placed on ePills.com. Our third party
vendors may not all be year 2000 compliant, and we rely upon the vendors to
implement patches or other contingency plans. The cost of developing and
implementing such measures could be expensive.

                                       20
<PAGE>

   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 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   % 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 access important
healthcare needs through electronic commerce 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 effective
medium of business and communication and as an important channel for the
delivery of healthcare information, products and services. We need to attract a
significant number of consumers, institutions and other participants in the
healthcare industry to our network. Rapid growth in the use of and interest in
the Internet has occurred only recently and, to date, consumers have generally
looked to healthcare professionals, not the Internet, as their principal source
for health and wellness information. As a result, acceptance and use of the
Internet may not continue to develop at historical rates, and a sufficiently
broad base of consumers may not adopt, and continue to use, the Internet and
other online services as a medium of acquiring healthcare information, products
and services.

   In addition, the Internet may not be accepted as a viable long-term
commercial marketplace for a number of reasons, including potentially
inadequate development of the necessary network infrastructure or delayed

                                       21
<PAGE>

development of enabling technologies and performance improvements. Our success
will depend, in large part, upon third parties maintaining the Internet
infrastructure to provide a reliable network backbone with the speed, data
capacity, security and hardware necessary for reliable Internet access and
services.

Internet capacity constraints could impede the development of our business.

   Our success depends upon a robust communications industry and infrastructure
for providing Internet access and carrying Internet traffic. 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, delays in the
adoption of new standards required to handle increased levels of Internet
activity, or increased government regulation. If the Internet continues to
experience significant growth in the number of users and level of transactions,
then the Internet infrastructure may not be able to continue to support the
demands placed on it. To the extent that our service is interrupted, our users
will be inconvenienced, our commercial customers will suffer from a loss in
advertising or service delivery and our reputation could be diminished.

If we do not respond to rapid technological changes, our services could become
obsolete and our business would be seriously harmed.

   As the Internet and online commerce industry evolve, we must license leading
technologies useful in our business, enhance our existing services, develop new
services and technology that address the increasingly sophisticated and varied
needs of our prospective customers and respond to technological advances 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. If we are unable to do so, it
could adversely impact our ability to build our brands and attract and retain
customers.

Governmental regulation of the Internet could affect our business.

   Laws and regulations directly applicable to communications or commerce over
the Internet are becoming more prevalent. The most recent session of the U.S.
Congress resulted in Internet laws regarding children's privacy, copyrights,
taxation and the transmission of sexually explicit material. The European Union
recently enacted its own privacy regulations. 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. It may
take years to determine whether and how existing laws such as those governing
privacy, libel and taxation apply to Internet websites like ours. 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, companies that maintain medical or pharmaceutical records. The
adoption or modification of laws or regulations relating to the Internet
business could adversely affect our ability to attract and serve customers. For
a more complete description of the risks we face relating to government
regulation of the Internet as it relates to our business, please see
"Business--Other Governmental Regulation."

The health industry is extremely dynamic and constantly changing, and thus our
business may be affected in unexpected ways.

   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. Health care 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, and investors will be relying on the judgment of
our management regarding the application of these proceeds. Presently,
anticipated uses include working capital, sales and marketing, funding
contractual obligations, including cash payments in the aggregate amount of
$46.6 million to AltaVista and America Online, website and content development,
infrastructure improvement, funding operating losses and potential
acquisitions. We may also use a portion of the proceeds for strategic alliances
and acquisitions and to repay debt. We have not yet determined the aggregate
amount of net proceeds to be used specifically for the foregoing purposes.

The liquidity of our common stock is uncertain because it has not been publicly
traded.

   There has not been a public market for our common stock. We cannot predict
the extent to which investor interest in our company will lead to the
development of an active, liquid trading market. Active trading markets
generally result in lower price volatility and more efficient execution of buy
and sell orders for investors. The initial public offering price for the shares
will be determined by negotiations between us and the representatives of the
underwriters and may not be indicative of prices that will prevail in the
trading market.

The stock market has experienced significant price and trading volume
fluctuations, and the market prices of Internet-related companies have been
extremely volatile.

   Recent initial public offerings by Internet companies have been accompanied
by exceptional share price and trading volume changes in the first days and
weeks after the securities were released for public trading. Investors may not
be able to resell their shares at or above the initial public offering price.

   If our future quarterly operating results are below the expectations of
securities analysts or investors, the price of our common stock would likely
decline. In the past, securities class action litigation has often been brought
against a company 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 initial public offering price of $   per share will be only
$  . In addition, we have issued options and warrants to acquire common stock
at prices significantly below the initial public offering price. You may incur
additional dilution if holders of stock options or warrants, whether currently
outstanding or subsequently granted, exercise their options or warrants to
purchase common stock.

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. Based on
shares outstanding as of August 31, 1999, upon completion of this offering, we
will have outstanding          shares of common stock, assuming no exercise of
the underwriters' over-allotment option assuming no exercise of options or
warrants. This includes

                                       23
<PAGE>

           shares that we are selling in the offering, which may be resold
immediately in the public market. The remaining 13,528,790 shares will become
eligible for resale in the public market as follows:

  . 5,095,195 shares will be eligible for sale 180 days from the effective
    date, due to agreements the holders of these shares have with us and the
    underwriters.

  . 7,142,795 shares will be eligible for resale within 180 days and 365 days
    after the effective date due to the requirements of federal securities
    laws.

  . 1,290,800 shares will be eligible for sale 365 days from the date of this
    prospectus due to an agreement the holder of these shares has with us

                                     *****

               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. Moreover, neither we nor any other
person assumes responsibility for the accuracy and completeness of such
statements. We are under no duty to update any of the forward-looking
statements after the date of this prospectus to conform such statements to
actual results.

                                USE OF PROCEEDS

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

   We currently expect to use the net proceeds primarily for working capital,
sales and marketing, funding contractual obligations, including cash payments
in the aggregate amount of $46.6 million to America Online and AltaVista over
the next two years, website and content development, infrastructure
improvements and funding 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 we
generate from operations. 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 June
30, 1999 was $   . 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 June 30, 1999, and includes the pro forma effects
of the following events:

  . the automatic conversion of all outstanding shares of preferred stock
    into 5,657,065 shares of common stock

  . the acquisition of Windom Health in August 1999, including $51,000 in
    cash, $458,000 in notes payable and 2,357,341 shares of common stock
    valued at $3.95 per share issued to shareholders of Windom Health in
    connection with the acquisition;

  . the net proceeds of $19.8 million from the sale of 4,523,065 shares of
    Series B preferred stock in August and September 1999; and

  . the acquisition of ePills.com in September 1999, including 1,776,923
    shares of common stock valued at $8.10 per share issued to, or reserved
    for issuance pursuant to the assumption of options held by, shareholders
    of ePills.com in connection with the acquisition.

   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
June 30, 1999 would have been $  , or $   per share. This represents an
immediate increase in pro forma net tangible book value of $   per share to
existing stockholders and an immediate dilution of $   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

                    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 website development and consulting
services company 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 September 1999, we acquired ePills.com, our
online drug store.

   We have historically derived revenue from advertising sales, generally
short-term banner advertisements or sponsorships. We record advertising
revenues in the period the advertising services are provided to customers. We
currently use an outside vendor, DoubleClick, to solicit customers to use its
advertising services, to serve the ads to our website and to bill and collect
for these services. This outside vendor provides monthly reports indicating the
amount billed for our advertising services and the related administrative fee.
Advertising revenues, as reported by the outside vendor, are recorded net of
this administrative fee as we bear no collection risk for the gross amount of
the advertising fees. In addition, our ePills.com subsidiary will provide us
with e-commerce revenues from sales of health-related products through our
online drug store.

   In order to implement our e-commerce strategy, we acquired ePills.com in
September 1999. In July and September 1999, ePills.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 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 $86 in 1996, $1,148 in 1997,
$446,235 in 1998 and $1,958,509 for the six months ended June 30, 1999. We
anticipate that we will incur additional operating losses for the foreseeable
future.

Recent Events

   In May 1999, pursuant to a letter of intent executed in 1998, we entered
into a definitive agreement to specify the terms of our acquisition of Windom
Health. The acquisition was completed on August 12, 1999, at which date Windom
Health became a wholly-owned subsidiary of HealthCentral.com. In connection
with the

                                       30
<PAGE>

acquisition, we issued 2,357,341 shares of common stock, notes payable in the
aggregate amount of $458,000 and paid cash of $51,000, representing a total
purchase price of approximately $13.8 million.

   This acquisition was accounted for using the purchase method of accounting.
We recorded intangibles and goodwill of approximately $12,455,000, 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 $555,000.

   In August and September 1999, we sold 4,523,065 shares of Series B preferred
stock to investors resulting in total net proceeds of $19.8 million. Each share
of Series B preferred stock is convertible into one share of common stock upon
closing of this offering.

   In September 1999, we acquired ePills.com in exchange for 1,776,923 shares
of common stock issued to, or reserved for issuance pursuant to the assumption
of options held by, ePills.com stockholders, and the assumption of liabilities,
representing a total purchase price of approximately $14.9 million. This
acquisition was accounted for using the purchase method of accounting. We
recorded intangibles and goodwill of approximately $13,197,000 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.

   If AltaVista meets given performance thresholds under our agreement
regarding our co-branded health channel, 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. If the market value of our common stock
exceeds the warrant exercise price on the date of issuance or during the
exercise period, there would be a deferred compensation charge associated with
the exercise of each of these warrants.

Results of Operations

 Six Months Ended June 30, 1999 and 1998

   Revenues. Revenues consist of advertising revenues principally from short-
term banner advertisements or sponsorships. Our total revenues increased to
$126,546 for the six months ended June 30, 1999 from $0 for the six months
ended June 30, 1998. The 1999 revenues resulted primarily from initial
advertising revenues after the launch of the HealthCentral.com website in
November 1998.

   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 $496,197 for the six months ended June 30, 1999 from $0 for the
six months ended June 30, 1998. The 1999 expenses were primarily attributable
to personnel-related costs in connection with recruiting our production and
engineering staff for the HealthCentral.com website and new content. 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 increased to $435,458 for
the six months ended June 30, 1999 from $0 for the six months ended June 30,
1998. The 1999 sales and marketing expenses were primarily attributable to
salaries and benefits paid to new sales personnel. 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
$257,988 for the six months ended June 30, 1999 from $2,619 for the six months
ended June 30, 1998. The increase was primarily

                                       31
<PAGE>

related to personnel and legal expense in order 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.

   Amortization of 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 six months
ended June 30, 1999, we had recorded a total of $3,055,553 of deferred stock
compensation. We recognized amortization of stock compensation of $902,931 for
the six months ended June 30, 1999. Deferred stock compensation is being
amortized over the respective vesting periods of the outstanding options,
generally 4 years. We expect amortization expense to substantially increase in
future periods for options granted after June 30, 1999.

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

   Revenues. Our total revenues were $15,259 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 $136,788 in 1998. There were no expenses in 1997 and
1996. Expenses in 1998 were primarily attributable to personnel costs
associated with the development of the HealthCentral.com website.

   Sales and Marketing. Sales and marketing expenses were $141,516 in 1998, an
increase of $140,668 over 1997 expenditures of $848. The increase in sales and
marketing expenses was primarily attributable to personnel related expenditures
as a result of the commencement of our sales and marketing efforts.

   General and Administrative. General and administrative expenses were $78,549
in 1998, an increase of $78,249 over 1997 expenditures of $300. The increase in
general and administrative expenses in 1998 was primarily due to increases in
personnel and professional services, travel and facilities-related expenses
incurred to support the commencement and growth of our operations.

   Amortization of Stock Compensation. Through December 31, 1998, we had
recorded a total of $389,122 of deferred stock compensation. We recognized
amortization of stock compensation of $104,641 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 a note payable. As of June 30, 1999,
we had $69,383 in cash and cash equivalents. Net cash provided by financing
activities was $1,935,025 in 1998, which was primarily the result of our
preferred stock financing in December 1998. Net cash provided by financing
activities was $507 in 1997, which was the result of the sale of common stock.
Net cash provided by financing activities was $7,500 in 1996, which was the
result of the sale of common stock. In August and September 1999, we sold
4,523,065 shares of Series B preferred stock resulting in net cash proceeds of
approximately $19.8 million.

   Net cash used in operating activities was $723,979 in the six months ended
June 30, 1999 and $286,706 in 1998, which was primarily the result of net
operating losses and increases in prepaid expenses, partially

                                       32
<PAGE>

reduced by non-cash stock compensation expense and increases in deferred
revenue. Net cash used in operating activities was $1,148 in 1997, which was
primarily the result of a net operating loss. Net cash used in operating
activities in 1996 was $86.

   Net cash used in investing activities was $798,189 for the six months ended
June 30, 1999, $563,541 in 1998 and $0 in 1997. Cash used in investing
activities in 1999 and 1998 was primarily related to bridge loans to Windom
Health. There were no changes in cash flows as a result of investing activities
in 1996.

   As of June 30, 1999, our principal commitment consisted of an obligation
outstanding under the terms of a $500,000 bridge loan. This loan was repaid in
full in August 1999. 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.
In addition, in August 1999, ePills.com entered into a two-year agreement with
America Online under which ePills.com will appear as an anchor tenant on the
America Online HealthOnline Pharmacy Channel and receive a minimum number of
advertising impressions in exchange for payments of $14.1 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 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. Additionally, we will continue to evaluate possible
acquisitions of or investments in complementary businesses, technologies,
services or products and plan to expand our sales and marketing programs. We
currently believe that our available cash and cash equivalents at September 24,
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

                                       33
<PAGE>

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 June 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 are dependent to conduct our operations are
not year 2000 compliant. Our potential areas of exposure include products
purchased from third parties, information technology, including computers and
software, and non-information technology, including telephone systems and other
equipment used internally. The reasonably likely worst case scenario for year
2000 issues would be if a significant defect exists in key hardware or software
and if a solution for such a problem were not immediately available. If a
problem is detected in these subsystems during our year 2000 compliance testing
process, these components will need to be revised or replaced.

   We do not currently have a complete contingency plan to deal with the worst-
case scenario that might occur if technologies we are dependent upon are not
year 2000 compliant and fail to operate effectively after the year 2000. We
intend to develop a plan for this scenario upon the completion of our
compliance assessment plan. This contingency plan is expected to be completed
by early in the fourth quarter of 1999.

   All areas that are vital to our operations are being tested and validated
for year 2000 compliance. We have completed our year 2000 compliance assessment
plan and expect to complete our compliance testing and related documentation by
the end of the fourth quarter. Until our testing is complete we will not be
able to evaluate whether our systems will need to be revised or replaced, or
the cost involved. We have contacted all our major third party vendors. Of
these vendors, 100% have had written statements concerning their year 2000
compliance and strategy on their websites or in their software documentation.
Of the vendors that have replied, 60% are representing that they are year 2000
compliant, while 40% are still in the process of fixing any known year 2000
problems or have already identified specific patches available that we will
need to install and verify. To the extent that vendors fail to provide
certification that they are year 2000 compliant, we will seek to terminate and
replace those relationships.

   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 vendors
that sell industry-standard software upon which we rely to ensure compliance,
and the lack of dependency on older legacy software in our systems.

   In the event that our production and operational facilities that support our
websites are not year 2000 compliant, portions of our websites may become
inaccessible. A prolonged disruption in our operations could cause our business
clients and consumers to stop doing business with us. Our review of our systems
has shown that there is no single application that would make our websites
totally unavailable and we believe that we can quickly address any difficulties
that may arise. In the event that 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 such time as 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 distributors, suppliers and other third parties with whom we
conduct business do not successfully address such issues, our business could be
significantly disrupted.

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.

 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

                                       35
<PAGE>

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 31.6% of surveyed Internet users shopped for
healthcare 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 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.

                                       36

   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, and our ePills.com online drug store.
We also plan to launch our PeoplesPharmacy.HealthCentral.com website and our
MediaLinx Canadian affiliate in the fourth quarter of 1999, and 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. ePills.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. ePills.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, ePills.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 various interactive tools, 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 400,000 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 enables 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 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 ePills.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 daily Medical Minutes
    radio programs typically aired during morning and evening rush hour
    traffic. Dr. Edell reaches 13 million radio listeners weekly, according
    to the Arbitron report. Dr. Edell also has a daily syndicated television
    report, which is broadcast in over 50 markets, including seven of the
    20 largest television markets in the United States. According to AC
    Nielsen, Dr. Edell reaches over 7 million television viewers each week.
    We expect that the television broadcast will be rebranded as The
    HealthCentral.com Report upon annual syndication renewals beginning in
    October 1999.

  . The People's Pharmacy. Teresa and Joe Graedon write The People's
    Pharmacy, a newspaper column, syndicated by King Features and published
    three times a week in over 100 markets, including

                                       38
<PAGE>

   New York, Baltimore, Los Angeles, Boston and Chicago. The Graedons also
   host a weekly radio show that is broadcast on over 500 stations in more
   than 100 countries. In addition, they are the authors of ten books,
   including The People's Pharmacy, a New York Times No. 1 best seller. In
   the fourth quarter of 1999, we expect to launch 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. In August 1999, ePills.com entered
    into a two-year agreement with America Online, under which ePills.com
    will appear as one of the five health-related anchor tenants on the
    America Online HealthOnline Pharmacy Channel. In the fourth quarter of
    1999, we expect to launch 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. We currently receive revenue from three different sources:

  . 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 400,000 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. 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. ePills.com, our online drug store, offers prescription
    pharmaceutical products, health and beauty aids, parenting and personal
    care products and nutritional supplements. ePills.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 28 employees and consultants 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 ePills.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 and
     PeoplesPharmacy.HealthCentral.com;

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

  .  expanding our broad range of consumer products and services;


                                      39
<PAGE>

  .  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;

  .  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 increased competitive
advantage.

   ePills.com

   ePills.com, our online drug store, was founded in January 1999 and in
September 1999 launched its website. ePills.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. ePills.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.

   ePills.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 ePills.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 ePills.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. Chronic illnesses represent
    approximately 73% of the U.S. prescription drug market according to
    Advanstar Communications. 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 @ ePills.com

   Customers at ePills.com can fill prescriptions and shop for brand name
health and beauty aids online from the privacy and convenience of their homes.
The ePills.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 ePills.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 ePills.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 ePills.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
     ePills.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.

 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.

Customers

 Consumer

   In August 1999, according to an audit completed by Nielsen I/PRO,
www.healthcentral.com attracted 5 million page views and 1,174,726 total

measured 599,400 unique users during that same month. Page views are the total
number of complete pages retrieved and viewed by visitors to the
HealthCentral.com website. Each single-session use of the website constitutes a
visit, and a unique user is an individual visitor to the HealthCentral.com
website.

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

                                       45
<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, ePills.com entered into a two-year agreement
with America Online, under which ePills.com will appear as one of five health-
related anchor tenants on the America Online HealthOnline Pharmacy Channel.
ePills.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 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
three times a week in over 100 markets, including New York, Baltimore, Los
Angeles, Boston and Chicago. They also host a weekly radio show that is
broadcast on over 500 stations in more than 100 countries. 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 200,000 shares of our common stock.

   MediaLinx. In the fourth quarter of 1999, we expect to launch 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

                                       46
<PAGE>

tools that integrate with evolving healthcare standards. Our HealthCentral.com
and ePills.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 ePills.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

   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 website.
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 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.

 ePills.com

   Our current sales and marketing strategy is to establish brand awareness and
build brand loyalty of ePills.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.

                                       47
<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., ePills.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

   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 consumer website competes 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.

 ePills.com

   The online e-commerce markets in the health, beauty, wellness, personal care
and pharmacy categories are fragmented and intensely competitive, with no clear
dominant leader in any of our market categories. 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;

                                       48
<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.

 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 intend to file for federal trademark registrations for
the mark HealthCentral.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."

   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 or inability
to protect our intellectual property rights could adversely affect 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
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; and

  .  advertising of drugs, cosmetics and nutritional supplements.

   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.

   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/ePills.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.


                                       51

   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 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.

   Use of Medical Information and Data. There are changing federal and state
laws governing the storage 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.

   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 where
a portion of such remuneration is offered, paid, solicited or received for a
lawful purpose. Certain courts

                                       52
<PAGE>

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 equipment covered by federal or state self-
referral laws, the manner in which we are paid by the referral

                                       53
<PAGE>

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.

   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

                                       54
<PAGE>

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 have 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 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.

                                       55
<PAGE>

   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 ePills.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 September 15, 1999 we had 47 employees, of which 6 were employed in
sales and marketing, 15 were employed in engineering, 17 were employed in
production, and 9 were employed in general management and administration. We
believe that our relations with our employees is good.

Facilities

   We lease an aggregate of approximately 16,100 square feet at our two
facilities in Emeryville, California. The lease for approximately 7,300 square
feet expires in March 2004 and the lease for approximately 8,800 feet expires
in December 2003. 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 into the following three classes, each serving
staggered three-year terms, after the completion of this offering: 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.

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.

                                       61
<PAGE>

   Messrs. Greene and Toney also have change of control provisions, which
provide that fifty percent (50%) 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 vests on our
acquisition by another company and the remaining fifty percent vests 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 of nonstatutory
stock options and stock purchase rights to employees, directors (including
employee 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, 280,000 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 4,900,000 shares, and to incorporate certain other
changes, after which amendment a total of 5,180,000 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 882,000 shares, 3.5% of our outstanding common stock on the last day
of the immediately preceding fiscal year, or such lesser number of shares as
the board of directors determines. This amendment to the 1999 plan will be
submitted for approval by our stockholders prior to the completion of this
offering. Unless terminated earlier by the board of directors, the 1999 plan
will terminate in August 2009.

   As of August 31, 1999, options to purchase 280,000 shares of common stock
were outstanding under the 1999 plan at a weighted average exercise price of
$1.14 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

                                       62
<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 such 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, each outstanding option and stock
purchase right may be assumed or an equivalent award substituted by our
acquirer. However, if the acquirer does not agree to such assumption or
substitution, outstanding awards will become fully vested and exercisable
immediately prior to the consummation of the transaction. 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
in August 1998 and approved by our stockholders in August 1998. The 1998 plan
provides for the grant to employees of incentive stock options and the grant of
nonstatutory stock options and stock purchase rights to employees, consultants
and directors. An aggregate of 3,360,000 shares of common stock have been
reserved for issuance under the 1998 plan. As of August 31, 1999, options to
purchase 1,890,177 shares of common stock at a weighted average exercise price
of $0.67 were outstanding under this plan, 376,758 shares with a weighted
average purchase price of $1.08 have been issued upon exercise of options or
stock purchase rights and 1,093,064 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
with respect to the following features. The 1998 plan imposes a limitation of
1,400,000 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. In addition, the 1998 plan does not allow for the granting of
nonstatutory stock options with any transferability rights.

   1999 Employee Stock Purchase Plan. Our 1999 employee stock purchase plan was
adopted by our board of directors in September 1999 and will be submitted for
approval by our stockholders prior to completion of this offering. A total of
1,400,000 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
490,000 shares, 2% of our outstanding common stock on the last day of the
immediately preceding fiscal year, or such 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 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

                                       63
<PAGE>

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 any such 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, which in any event may not
exceed 20% of an employee's base salary. 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 such
employee 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 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 2,800 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 shall 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 exercise 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.

   1999 Directors' Stock Option Plan. The 1999 directors' stock option plan was
adopted by the board of directors in September 1999 and will be submitted for
approval by our stockholders prior to completion of this offering. It will
become effective upon the date of this offering. A total of 350,000 shares of
common stock has been reserved for issuance under 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 such 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 14,000 shares of common stock on the date on which
such individual 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 7,000 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 on the date of grant
and will be nontransferable. All options granted under the

                                       64
<PAGE>

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 such 90-day period, the option shall 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 such action
does not adversely affect any outstanding option and we 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
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.

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

services and development of products. 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 (1) health care
systems consulting, (2) enterprise engineering, (3) health information systems

shares of common stock at an exercise price of $0.22 per share, which shares

January 1999, the option's vesting commencement date. In connection with

notes in the aggregate principal amount of $400,000 bearing interest at 5.74%

plus accrued interest.

   In August 1999, we granted to Marcos A. Athanasoulis an immediately
exercisable option to purchase 70,000 shares of our common stock at an exercise

at an exercise price of $7.31 per share, which shares vest over a 48 month
period beginning in September 1999. In August 1999, we granted to Ann-Marie
Buddrus an immediately exercisable option to purchase 70,000 shares of our
common stock at an exercise price of $1.14 per share, which shares vest over a
48 month period beginning in September 1998.

   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, a member of our board of directors, which 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.

                             PRINCIPAL STOCKHOLDERS

   The following table sets forth information known to us with respect to
beneficial ownership of our common stock as of August 31, 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
13,528,790 shares of common stock outstanding as of August 31, 1999 and an
assumed     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 within 60 days after August 31, 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.

                          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 August 31, 1999, there were 13,528,790 shares of common stock
outstanding, held of record by approximately 46 stockholders, which reflects
the conversion of all outstanding shares of preferred stock into common stock.
Upon completion of this offering, there will be    shares of common stock
outstanding, assuming no exercise of the underwriters' overallotment option or
additional exercise of outstanding options or warrants after August 31, 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 5,657,065 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 August 31, 1999, warrants were outstanding to purchase an aggregate of
744,361 shares of common stock at a weighted average exercise price of $2.57
per share. Of these warrants, warrants to purchase an aggregate of 649,857
shares of common stock at a weighted average exercise price of $2.19 per share
will terminate upon the completion of this offering if not exercised prior to
such time. In addition, as of August 31, 1999, we 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.


Registration Rights

   As of August 31, 1999, the holders of 12,660,093 shares of common stock and
warrants to purchase 558,040 shares of common stock (the "registrable
securities") 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
the registrable securities. Subject to limitations specified in the agreement,
these registration rights include the following:

                                       71
<PAGE>

  .  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 25% of
the shares of our common stock issued to the former ePills.com stockholders in
connection with our acquisition of ePills.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 HealthCentral.com 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

  . 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.

                                       72
<PAGE>

   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 permit 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    outstanding shares of
common stock, based upon shares outstanding as of August 31, 1999 and assuming
no exercise of options or warrants. Of these shares, the    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 13,528,790 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 securityholders 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 5,095,195
    shares will be eligible for sale pursuant to Rule 144. All but 938,000 of
    such shares are held by affiliates.

  . Between 180 days and 365 days after the effective date, approximately
    7,142,795 shares under Rule 144 at various times. All but 3,756,345
    shares are held by affiliates.

  . Beginning 365 days after the effective date approximately 1,290,800
    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    shares immediately after the offering;
    or

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

                                       74
<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 registration statements under the Securities
Act as promptly as possible after the effective date to register shares to be
issued pursuant to our employee benefit plans. As a result, any options or
rights exercised under the 1999 Stock 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 statements 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 August 31, 1999, there were outstanding options
for the purchase of 1,890,177 shares of common stock.

   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    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           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

                                       76
<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 $    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.

   Any offers in Canada will be made only under an exemption from the
requirements to file a prospectus in the relevant province of Canada where the
sale is made.

initial public offering price set forth on the cover page of this prospectus.
These persons must commit to purchase no later than the close of business on

for sale to the general public will be reduced to the extent these persons
purchase the reserved shares.

   A prospectus in electronic format is being made available on an Internet
website maintained by Wit Capital. In addition, all dealers purchasing shares
from Wit Capital in the offering have agreed to make a prospectus in electronic
format available on websites maintained by each of these dealers. Purchases of
shares from Wit Capital are to be made through an account at Wit Capital in
accordance with Wit Capital's procedures for opening an account and transacting
in securities.

   Wit Capital, a member of the National Association of Securities Dealers,
Inc., will participate in the offering as one of the representatives. The
National Association of Securities Dealers, Inc. approved the membership of Wit
Capital on September 4, 1997. Since that time, Wit Capital has acted as an
underwriter, e-manager or selected dealer in over 125 public offerings. Except
for its participation as a representative in the offering, Wit Capital has no
relationship with us or any of our affiliates.

                       Report of Independent Accountants

   The reincorporation and stock split described in Note 1 to the financial
statements has not been consummated at September 24, 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 balance sheets and the related 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) at December 31, 1997 and 1998, and the results of its operations
and its 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, 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 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 September 1999, the Company's Board of Directors authorized 1) the
reincorporation of the Company in Delaware, and 2) a 1.4-for-1 stock split of
its common and preferred stock, both subject to shareholder approval.

   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.

 Development stage enterprise

   For the period from inception through June 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 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.

 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.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


 Pro forma stockholders' equity

   The pro forma stockholders' equity as of June 30, 1999 reflects the
conversion of all outstanding shares of convertible preferred stock into an
aggregate of 1,134,000 shares of common stock.

 Comprehensive income

   The Company adopted the provisions of Statement of Financial Accounting
Standards ("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
services are provided 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 amounts billed for the Company's
advertising services and the related administrative fee. Advertising revenues,
as reported by the outside vendor, are recorded net of this administrative fee
as the Company bears no collection risk for the gross amount of the advertising
fees.

 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 six months
ended June 30, 1999 was $157,374 (unaudited).

 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 ("SAB") 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 convertible
preferred stock.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   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:

 Pro forma net loss per share (unaudited)

   Pro forma net loss per share for the year ended December 31, 1998 and the
six months ended June 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 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
six months ended June 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 2--RELATED PARTY TRANSACTIONS

   In August 1998, in association with a letter of intent relating to a merger
transaction (Note 8), the Company entered into a License and Management
Agreement (the "Agreement") with Windom Health Enterprises, Inc. ("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 and June 30, 1999, the net outstanding balance due from Windom Health
amounted to $563,541 and $1,361,730 (unaudited), respectively. The cumulative

</TABLE>

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

 Voting

   Each share of Series A 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 1,400,000 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 convertible preferred stock are entitled to receive
noncumulative dividends at the per annum rate of $0.14 per share, when and if
declared by the Board of Directors. The holders of Series A will also be
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 have been declared by the Board from inception through December 31, 1998.

 Liquidation

   In the event of any liquidation, dissolution or winding up of the Company,
including a merger, acquisition or sale of assets where the beneficial owners
of the Company's common stock and convertible preferred stock own less than 51%
of the resulting voting power of the surviving entity, the holders of Series A

preferred stock are entitled to receive an amount of $1.79 per share, 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 convertible preferred
stockholders.

 Conversion

   Each share of Series A 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
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 at a
per share price of at least $3.57 per share with gross proceeds of at least
$7,500,000, (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 warrants to purchase 544,320 shares of Series
A convertible preferred stock at an exercise price of $1.79 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 $1.36 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 13,720 Series A convertible preferred stock warrants at
an exercise price of $1.79 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 $4.10 per share. The fair value of the warrants
of $49,372 is being amortized over the period of the leases.

NOTE 4--COMMON STOCK:

   The Company's Articles of Incorporation, as amended, authorize the Company
to issue 26,600,000 shares of $0.001 par value common stock. A portion of the
shares sold are subject to a right of repurchase by the Company subject to
vesting over a one year period. At December 31, 1998, there were 20,090 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 80,784 shares of the Company's common stock at an
exercise price of $5.81 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 $4.44 per share. The fair value of the warrant of
$152,843 will be amortized over the period of the content license agreement.

NOTE 5--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.

   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.

   During the period from January 1, 1998 through June 30, 1999, the Company
recorded $3,444,675 of deferred stock compensation in accordance with SFAS 123
and Emerging Issues Task Force 96-18, related to options granted to
consultants in 1998 and 1999. During this period the Company determined the
fair value of each option grant using the Black-Scholes option pricing model
with the following assumptions: expected lives of one to four years; weighted
average risk-free rates between 4.2% and 5.9%; expected dividend yield of zero
percent; expected volatility of 70% and deemed values of common stock between
$1.36 and $5.36 per share. Stock compensation expense is being recognized in
accordance with FIN 28 over the vesting periods of the related options,
generally four years. The Company recognized stock compensation expense of
$104,641 and $902,931 (unaudited) for the year ended December 31, 1998 and the
six months ended June 30, 1999, respectively. The Company will recognize
material amounts of stock compensation expense in the future resulting from
additional options granted after June 30, 1999.

   The total purchase price of $13.8 million consisted of cash of $51,000, a
note payable of $458,000, 2,357,341 shares of the Company's common stock valued
at $9,311,514, assumed liabilities of $3,956,000 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 $3.95 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 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.

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

   In September 1999, the Company entered into an acquisition agreement with
ePills, Inc. ("ePills"). ePills operates an online drug store which provides
retail sales of prescription pharmaceuticals, over-the-counter products and
health and beauty aids on the Internet.

number of shares reserved for issuance by 4,900,000 shares, and to incorporate
certain other changes, after which amendment a total of 5,180,000 shares of

                         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. License revenues are recognized ratably over the term of the
license, generally between 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

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.

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.

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

 The Company

   ePills 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 June 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 June 30, 1999 and for the period from
inception to June 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.

 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 is responsible for all refunds relating to
sales where a customer is not satisfied with the products received. The Company
provides an estimated allowance for such returns in the period of the sale. The
Company also retains credit risk for sales of all products made by its
fulfillment partners.

   Depreciation expense was $2,700 for the period ended June 30, 1999.

NOTE 3--NOTE PAYABLE TO STOCKHOLDERS:

   During the period from January 27, 1999 to June 30, 1999, stockholders of
the Company advanced the Company $270,000 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 6).
Upon the completion of an IPO by HealthCentral.com, the notes are no longer
convertible. As of August 31, 1999, the balance due under the convertible notes
payable was $1,250,000.

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 June 30, 1999, the Company granted a total of 69,690
options to employees. Deferred stock compensation based on the deemed value of
common stock over the exercise prices on the dates of grant was not
significant.

   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.

NOTE 6--SUBSEQUENT EVENTS:

 Agreements

   In August 1999, the Company entered into an agreement with Bergen Brunswig
Drug Company to be its fulfillment service provider for over-the-counter and
health and beauty aid products and provide related services to the Company's
customers in the United States. In September 1999, in connection with the
agreement, the Company sold Bergen Brunswig 337,500 shares of common stock for
cash of $5.215 per share for an aggregate purchase price of $1.76 million.

   In August 1999, the Company also entered into an agreement with Medi-Mail,
Inc. (a subsidiary of Bergen Brunswig) in which Medi-Mail is to provide
pharmacy dispensing and related support services for the Company and its
consumers, including the processing, adjudication or verification and
fulfillment of prescription drug orders received by the Company through its
website and their delivery to the Company's shipper. In August 1999, in
connection with this agreement, the Company issued Medi-Mail a warrant to
purchase 52,630 shares of common stock at an exercise price of $3.70 per share,
which was exercised in connection with the signing of the acquisition agreement
with HealthCentral.com. The Company valued the warrant using the Black-Scholes
option pricing model, applying an expected life of one year, a weighted average
risk free rate of 5.88%, an expected dividend yield of zero percent, a
volatility of 70% and a deemed value of common stock of $8.10 per share. The
estimated fair value of the warrant of $253,045 will be amortized over the
period of the agreement.

   In August 1999, the Company entered into a two year agreement with America
Online, Inc. ("AOL"), under which the Company will appear as one of five
health-related anchor tenants on the AOL HealthOnline Pharmacy. The Company is
required to pay AOL approximately $14.1 million over the term of the agreement.

 Acquisition

   In September 1999, all of the Company's outstanding common stock was
acquired by HealthCentral.com for consideration of 1,776,923 shares of
HealthCentral.com common stock valued at $8.10 per share, the assumption of
8,460 stock options valued at $9.70 per share and the assumption of $332,000 of
liabilities.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

   On August 12, 1999 and September 24, 1999, HealthCentral.com acquired Windom
Health Enterprises, Inc. ("Windom Health") and ePills Inc. ("ePills.com"),
respectively, in transactions 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 individual
balance sheet of the Company at June 30, 1999 and the balance sheets of Windom
Health and ePills.com at June 30, 1999 assuming the transactions were
consummated on that date. 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 six months ended June 30, 1999.
The operations of Windom Health have been included in the unaudited pro forma
combined statements of operations as though that acquisition had been
consumated on January 1, 1998. The operations of ePills.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

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

NOTE 1--BASIS OF PRESENTATION

 Windom Health

   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 offers institutions, including healthcare
organizations, employers and pharmaceutical companies the ability to license
specialized tools and services to provide their members with personalized on-
line 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
preliminary allocation is summarized below:

<TABLE>

                                                                    Amortization
                                                                        Life
                                                                    ------------

                                                        ===========
</TABLE>

   The total purchase price of $13.8 million consisted of cash of $51,000, a
note payable of $458,000, 2,357,341 shares of the Company's common stock valued
at $9,311,514, assumed liabilities of $3,956,000 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 $3.95 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.

 ePills.com

   In September 1999, the Company entered into an acquisition agreement with
ePills. ePills is engaged in the development of an online drug store to provide
retail sales of prescription pharmaceuticals, over-the-counter products and
health and beauty aids on the Internet.

</TABLE>

   The total purchase price $14.9 million consisted of 1,776,923 shares of the
Company's common stock valued at $14,393,076, assumption of 11,844 shares of
employee stock options valued at $6.93 per share, assumed liabilities of
$332,000 and estimated transaction costs of $100,000. The deemed value of the
Company's common stock on the date the definitive merger agreement was signed
was $8.10 per share.

   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.

   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
Company, Windom Health or ePills.com for the periods presented.

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 six months ended June 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.

Item 14. Indemnification of Directors and Officers

   Section 145 of the Delaware General Corporation Law authorizes a court to
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
our certificate of incorporation (Exhibit 3.3 hereto) and Article VI of our
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
directors. The Underwriting Agreement (Exhibit 1.1) also provides for cross-
indemnification among HealthCentral.com and the underwriters with respect to
certain matters, including matters arising under the Securities Act.

Item 15. Recent Sales of Unregistered Securities

     (a) Since September 1, 1996, the Registrant has issued and sold the
following unregistered securities:

  (1) In December 1998, the Registrant issued and sold shares of Series A
      Preferred Stock convertible into an aggregate of 1,134,000 shares of
      common stock, and warrants to purchase 544,320 shares of Series A
      Preferred Stock at a purchase price of $1.79 to investors.

  (2) In May 1999, the Registrant issued a warrant to purchase 13,720 shares
      of Series A Preferred Stock at a purchase price of $1.79 per share to
      individuals affiliated with a lender in connection with a financing
      transaction.

  (3) In April 1999, the Registrant issued a warrant to purchase 80,784
      shares of Common Stock at a purchase price of $5.81 per share to a
      strategic partner.

  (4) In July 1999, the Registrant issued promissory notes in the aggregate
      principal amount of $600,000 to investors and warrants to purchase an
      aggregate of 18,666 shares of common stock at a purchase price of $3.21
      per share to investors.

                                     II-1
<PAGE>

  (5) In July 1999, we issued a promissory note in the principal amount of
      $100,000 to an individual. The principal amount of this note was
      converted into shares of Series B Preferred Stock and the interest was
      paid in full in September 1999.

  (6) In August 1999, the Registrant issued 2,357,341 shares of its common
      stock to individuals in connection with an acquisition of a company.

  (7) In August and September 1999, the Registrant issued and sold shares of
      Series B Preferred Stock convertible into an aggregate of 4,523,065
      shares of common stock to investors for an aggregate purchase price of
      $20,999,998.50.

  (8) In August 1999, we issued promissory notes in the aggregate principal
      amount of $300,000 and warrants to purchase 9,332 shares of Series B
      Preferred Stock at a purchase price of $3.21 per share to a stockholder
      in connection with a bridge financing. The principal amount of this
      note was converted into shares of Series B Preferred Stock and the
      interest was paid in full in September 1999.

  (9) In August, 1999 the Registrant issued to Hambrecht & Quist LLC a
      warrant to purchase 77,539 shares of Series B Preferred Stock at a
      purchase price of $4.64 per share.

  (10) As of August 31, 1999, 376,758 shares of common stock had been issued
       upon exercise of options or pursuant to restricted stock purchase
       agreements and 1,890,177 shares of common stock were issuable upon
       exercise of outstanding options under the Registrant's 1998 Stock
       Plan.

  (11) In August 1998, the Registrant effected a 1.844-for-1 split of its
       outstanding common stock in which every outstanding share of common
       stock was split into 1.844 shares of common stock.

  (12) Prior to the completion of this offering, the Registrant intends to
       effect a 1.4-for-1 split of its outstanding common stock in which
       every outstanding share of common stock will be split into 1.4 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 1.4-for-1 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)(9) 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)(10) 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)(11) and (12) 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 where affixed to the securities issued in such
transactions. All recipients had adequate access, through their relationships
with the Company, to information about the Registrant.

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.

                                  ARTICLE II

     The purpose of the Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of

                                  ARTICLE III

     (A) Classes of Stock.  The Corporation is authorized to issue two classes
         ----------------
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
                                          ------------       ---------------
The total number of shares which the Corporation is authorized to issue is
Twenty Six Million Nine Hundred Thousand (26,900,000) shares, each with a par
value of $0.001 per share.  Twenty Two Million Two Hundred Thousand (22,200,000)
shares shall be Common Stock and Four Million Seven Hundred Thousand (4,700,000)

     (B) Rights, Preferences and Restrictions of Preferred Stock.  The Preferred
         -------------------------------------------------------
Stock authorized by these Second Amended and Restated Articles of Incorporation
(the "Restated Articles") may be issued from time to time in one or more series.
The first series of Preferred Stock shall be designated "Series A Preferred
                                                         ------------------
Stock" and shall consist of One Million Two Hundred Eight Thousand Six Hundred
- -----
(1,208,600) shares. The second series of Preferred Stock shall be designated
"Series B Preferred Stock" and shall consist of Three Million Four Hundred
- -------------------------
Thousand (3,400,000) shares.  The rights, preferences, privileges, and
restrictions granted to and imposed on the Series A and Series B Preferred Stock
are as set forth below in this Article III(B).
<PAGE>

          1.   Dividend Provisions.  The holders of shares of Series A and
               -------------------
Series B Preferred Stock shall be entitled to receive dividends, out of any
assets legally available therefor, prior and in preference to any declaration or
payment of any dividend (payable other than in Common Stock or other securities
and rights convertible into or entitling the holder thereof to receive, directly
or indirectly, additional shares of Common Stock of the Corporation) on the
Common Stock of the Corporation, at the rate of (i) $0.20 per share per annum on
each outstanding share of Series A Preferred Stock (as adjusted for stock
splits, stock dividends or recapitalizations and the like with respect to such
shares) and (ii) $0.52 per share per annum on each outstanding share of Series B
Preferred Stock (as adjusted for stock splits, stock dividends or
recapitalizations and the like with respect to such shares), in each case
payable quarterly when, as and if declared by the Board of Directors. Such
dividends shall not be cumulative.

          2.   Liquidation.
               -----------

               (a)  Preference.  In the event of any liquidation, dissolution or
                    ----------
winding up of the Corporation, either voluntary or involuntary, the holders of
the Series A and Series B Preferred Stock shall be entitled to receive, prior
and in preference to any distribution of any of the assets of the Corporation to
the holders of Common Stock by reason of their ownership thereof, an amount per
share equal to (i) $2.50 per share for each outstanding share of Series A
Preferred Stock then held by them (the "Original Series A Issue Price") and (ii)
$6.50 per share for each outstanding share of Series B Preferred Stock then held
by them (the "Original Series B Issue Price"), plus declared but unpaid
dividends on such share (subject to adjustment of such fixed dollar amounts for
any stock splits, stock dividends, combination, recapitalizations or the like).
If, upon the occurrence of such event, the assets and funds thus distributed
among the holders of the Series A and Series B Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, the entire assets and funds of the Corporation
legally available for distribution shall be distributed ratably among the
holders of the Series A and Series B Preferred Stock in proportion to the
preferential amount each such holder is otherwise entitled to receive.

               (b)  Remaining Assets.  Upon the completion of the distribution
                    ----------------
required by subsection (a) of this Section 2, all of the remaining assets of the
Corporation available for distribution to shareholders shall be distributed
among the holders of the Common Stock pro rata based on the number of shares of
Common Stock held by each.

               (c)  Certain Acquisitions.
                    --------------------

                    (i)  Deemed Liquidation.  For purposes of this Section 2, a
                         ------------------
liquidation, dissolution or winding up of the Corporation shall be deemed to
occur if the Corporation shall sell, convey, or otherwise dispose of all or
substantially all of its property or business or merge into or consolidate with
any other corporation (other than a wholly-owned subsidiary corporation) or
effect any other transaction or series of related transactions in which the
shareholders of the Corporation immediately prior thereto own less than a
majority of outstanding shares of voting stock of the Corporation (or its
successor or parent) immediately

                                      -2-
<PAGE>

thereafter, provided that this Section 2(c)(i) shall not apply to a merger
            --------
effected solely for the purpose of changing the domicile of the Corporation.

                    (ii)  Valuation of Consideration.  In the event of a deemed
                          --------------------------
liquidation as described in Section 2(c)(i) above, if the consideration received
by the Corporation is other than cash, its value will be deemed its fair market
value. Any securities shall be valued as follows:

                         (A)  Securities not subject to investment letter or
other similar restrictions on free marketability:

                              (1) If traded on a securities exchange or The
Nasdaq National Market, the value shall be deemed to be the average of the
closing sale prices of the securities on such exchange over the thirty-day
period ending three (3) days prior to the closing;

                              (2) If actively traded over-the-counter other than
through The Nasdaq National Market, the value shall be deemed to be the average
of the closing bid or sale prices (whichever is applicable) over the thirty-day
period ending three (3) days prior to the closing; and

                              (3) If there is no active public market, the value
shall be the fair market value thereof, as determined in good faith by the Board
of Directors of the Corporation.

                         (B)  The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in Section 2(c)(ii)(A) to reflect the approximate fair
market value thereof, as mutually determined in good faith by the Board of
Directors of the Corporation and the holders of a majority of the shares of
Preferred Stock outstanding.

                    (iii) Notice of Transaction.  The Corporation shall give
                          ---------------------
each holder of record of Series A and Series B Preferred Stock written notice of
a transaction described in 2(c)(i) not later than ten (10) days prior to the
shareholders' meeting called to approve such transaction, or ten (10) days prior
to the closing of such transaction, whichever is earlier, and shall also notify
such holders in writing of the final approval of such transaction. The first of
such notices shall describe the material terms and conditions of the impending
transaction and the provisions of this Section 2, and the Corporation shall
thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place sooner than ten (10) days after the
Corporation has given the first notice provided for herein or sooner than ten
(10) days after the Corporation has given notice of any material changes
provided for herein; provided, however, that such periods may be shortened upon
the written consent of the holders of Preferred Stock that are entitled to such
notice rights or similar notice rights and

                                      -3-
<PAGE>

that represent at least a majority of the voting power of all then outstanding
shares of such Preferred Stock.

                    (iv) Effect of Noncompliance.  In the event the
                         -----------------------
requirements of this Section 2(c) are not complied with, the Corporation shall
forthwith either cause the closing of the transaction to be postponed until such
requirements have been complied with, or cancel such transaction, in which event
the rights, preferences and privileges of the holders of the Series A and Series
B Preferred Stock shall revert to and be the same as such rights, preferences
and privileges existing immediately prior to the date of the first notice
referred to in Section 2(c)(iii) hereof.

          3.   Redemption.  The Preferred Stock is not redeemable.
               ----------

          4.   Conversion.  The holders of the Series A and Series B Preferred
               ----------
Stock shall have conversion rights as follows (the "Conversion Rights"):
                                                    -----------------

               (a)  Right to Convert.  Subject to Section 4(c), each share of
                    ----------------
Series A and Series B Preferred Stock shall be convertible, at the option of the
holder thereof, at any time after the date of issuance of such share, at the
office of the Corporation or any transfer agent for such stock, into such number
of fully paid and nonassessable shares of Common Stock as is determined by
dividing (i) $2.50 in the case of the Series A Preferred Stock and (ii) $6.50 in
the case of the Series B Preferred Stock by the Conversion Price applicable to
such share, determined as hereafter provided, in effect on the date the
certificate is surrendered for conversion. The initial Conversion Price per
share shall be $2.50 for shares of Series A Preferred Stock and $6.50 for shares
of Series B Preferred Stock. Such initial Conversion Price shall be subject to
adjustment as set forth in Section 4(d).

               (b)  Automatic Conversion.  Each share of Series A and Series B
                    --------------------
Preferred Stock shall automatically be converted into shares of Common Stock at
the Conversion Price at the time in effect for such share immediately upon the
earlier of (i) except as provided below in Section 4(c), the Corporation's sale
of its Common Stock in a firm commitment underwritten public offering (the
"IPO") pursuant to a registration statement under the Securities Act of 1933, as
 ---
amended (the "Securities Act"), in which the Pre-Money Valuation (as defined
              --------------
below) of the Company is at least $125 million and which results in aggregate
cash proceeds to the Corporation of not less than $15,000,000 (net of
underwriting discounts and commissions) or (ii) the date specified by written
consent or agreement of the holders of two thirds (66 2/3%) of the then
outstanding shares of Preferred Stock, voting as a single class on an as-
converted basis.  Upon such automatic conversion, any declared but unpaid
dividends shall be paid in accordance with Section 4(c). For the purpose of this
subsection the term "Pre-Money Valuation" means the product obtained by
                     -------------------
multiplying (i) the per share public offering price by (ii) the number of shares
of Common Stock outstanding on the date on which the Form S-1 registration
statement for the IPO (the "Form S-1") is filed (assuming, for the purpose of
                            --------
calculating such number of shares of Common Stock (1) the conversion of all
shares of Preferred Stock then outstanding, (2) the exercise and conversion of
all options and warrants then outstanding, and (3) the issuance,

                                      -4-
<PAGE>

exercise and conversion of all shares then reserved for issuance under the
Company's stock and option plans).

               (c)  Mechanics of Conversion.  Before any holder of Series A or
                    -----------------------
Series B Preferred Stock shall be entitled to convert the same into shares of
Common Stock, such holder shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the Corporation or of any transfer
agent for such series of Preferred Stock, and shall give written notice to the
Corporation at its principal corporate office, of the election to convert the
same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. The Corporation shall,
as soon as practicable thereafter, issue and deliver at such office to such
holder of Preferred Stock, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of such series of Preferred Stock to be converted, and
the person or persons entitled to receive the shares of Common Stock issuable
upon such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock as of such date. If the conversion is in
connection with an underwritten offering of securities registered pursuant to
the Securities Act the conversion may, at the option of any holder tendering
such Preferred Stock for conversion, be conditioned upon the closing with the
underwriters of the sale of securities pursuant to such offering, in which event
the person(s) entitled to receive Common Stock upon conversion of such Preferred
Stock shall not be deemed to have converted such Preferred Stock until
immediately prior to the closing of such sale of securities.

               (d)  Conversion Price Adjustments of Preferred Stock for Certain
                    -----------------------------------------------------------
Dilutive Issuances, Splits and Combinations.  The Conversion Price of the Series
- -------------------------------------------
A and Series B Preferred Stock shall be subject to adjustment from time to time
as follows:

                    (i)  Issuance of Additional Stock below Purchase Price.  If
                         -------------------------------------------------
the Corporation shall issue, after the date upon which any shares of Series B
Preferred Stock were first issued (the "Purchase Date"), any Additional Stock
                                        -------------
(as defined below) without consideration or for a consideration per share less
than the Conversion Price for a series in effect immediately prior to the
issuance of such Additional Stock, the Conversion Price for such series in
effect immediately prior to each such issuance shall automatically be adjusted
as set forth in this Section 4(d)(i), unless otherwise provided in this Section
4(d)(i).

                         (A)  Price Adjustment. Whenever the Conversion Price
                              ----------------
is adjusted pursuant to this Section 4(d)(i), the new Conversion Price shall be
determined by multiplying the Conversion Price then in effect by a fraction, (x)
the numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such issuance (the "Outstanding Common") plus the number of
                                         ------------------
shares of Common Stock that the aggregate consideration received by the
Corporation for such issuance would purchase at such Conversion Price; and (y)
the denominator of which shall be the number of shares of Outstanding Common
plus the number of shares of such Additional Stock.  For purposes of the
foregoing calculation,

                                      -5-
<PAGE>

the term "Outstanding Common" shall include shares of Common Stock deemed issued
pursuant to Section 4(d)(i)(E) below.

                         (B)  Definition of "Additional Stock".  For purposes
                              --------------------------------
of this Section 4(d)(i), "Additional Stock" shall mean any shares of Common
                          ----------------
Stock issued (or deemed to have been issued pursuant to Section 4(d)(i)(E)) by
the Corporation after the Purchase Date) other than

                              (1) Common Stock issued pursuant to a transaction
described in Section 4(d)(ii) hereof,

                              (2) Shares of Common Stock issuable or issued to
employees, consultants or directors of the Corporation pursuant to restricted
stock purchase or stock option plans or agreements approved by the Board of
Directors of the Corporation,

                              (3) Capital stock, or options or warrants to
purchase capital stock, issued to financial institutions or other lenders or
lessors in connection with loans, leases, equipment financings or similar
transactions,

                              (4) Shares of Common Stock or Preferred Stock
issuable upon exercise of warrants outstanding as of the date of these Amended
and Restated Articles of Incorporation (and issuable on the conversion of shares
issuable upon such exercise),

                              (5) Capital stock or warrants or options to
purchase capital stock issued in connection with bona fide acquisitions, mergers
or similar transactions, the terms of which are approved by the Board of
Directors of the Corporation,

                              (6) Shares of Common Stock issued or issuable upon
conversion of the Series A or Series B Preferred Stock,

                              (7) Shares of Common Stock issued or issuable in a
public offering prior to or in connection with which all outstanding shares of
Preferred Stock will be converted to Common Stock, and

                              (8) Securities issued in connection with research
and development partnerships, licensing or collaborative arrangements and
similar transactions approved by the Board of Directors of the Corporation.

                         (C)  No Fractional Adjustments.  No adjustment of the
                              -------------------------
Conversion Price for the Series A or Series B Preferred Stock shall be made in
an amount less than one cent per share, provided that any adjustments which are
not required to be made by reason of this sentence shall be carried forward and
shall be either taken into account in any subsequent adjustment made prior to
three years from the date of the event giving rise to the adjustment being
carried forward, or shall be made at the end of three years from the date of the
event giving rise to the adjustment being carried forward.

                                      -6-
<PAGE>

                         (D)  Determination of Consideration.  In the case of
                              ------------------------------
the issuance of Common Stock for cash, the consideration shall be deemed to be
the amount of cash paid therefor before deducting any reasonable discounts,
commissions or other expenses allowed, paid or incurred by the Corporation for
any underwriting or otherwise in connection with the issuance and sale thereof.
In the case of the issuance of the Common Stock for a consideration in whole or
in part other than cash, the consideration other than cash shall be deemed to be
the fair value thereof as determined by the Board of Directors irrespective of
any accounting treatment.

                         (E)  Deemed Issuances of Common Stock.  In the case of
                              --------------------------------
 the issuance (whether before, on or after the Purchase Date) of options to
purchase or rights to subscribe for Common Stock, securities by their terms
convertible into or exchangeable for Common Stock or options to purchase or
rights to subscribe for such convertible or exchangeable securities, the
following provisions shall apply for all purposes of this Section 4(d)(i):

                              (1)  The aggregate maximum number of shares of
Common Stock deliverable upon exercise (assuming the satisfaction of any
conditions to exercisability, including without limitation, the passage of time,
but without taking into account potential antidilution adjustments) of such
options to purchase or rights to subscribe for Common Stock shall be deemed to
have been issued at the time such options or rights were issued and for a
consideration equal to the consideration (determined in the manner provided in
Section 4(d)(i)(D)), if any, received by the Corporation upon the issuance of
such options or rights plus the minimum exercise price provided in such options
or rights (without taking into account potential antidilution adjustments) for
the Common Stock covered thereby.

                              (2)  The aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange (assuming the
satisfaction of any conditions to convertibility or exchangeability, including,
without limitation, the passage of time, but without taking into account
potential antidilution adjustments) for any such convertible or exchangeable
securities or upon the exercise of options to purchase or rights to subscribe
for such convertible or exchangeable securities and subsequent conversion or
exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal
to the consideration, if any, received by the Corporation for any such
securities and related options or rights (excluding any cash received on account
of accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Corporation (without taking into
account potential antidilution adjustments) upon the conversion or exchange of
such securities or the exercise of any related options or rights (the
consideration in each case to be determined in the manner provided in Section
4(d)(i)(D).

                              (3)  In the event of any change in the number of
shares of Common Stock deliverable or in the consideration payable to the
Corporation upon exercise of such options or rights or upon conversion of or in
exchange for such convertible or exchangeable securities, including, but not
limited to, a change resulting from the antidilution provisions thereof, the
Conversion Price of the Series A or the Series B Preferred Stock, to the extent
in any way affected by or computed using such options, rights or securities,
shall be

                                      -7-
<PAGE>

recomputed to reflect such change, but no further adjustment shall be made for
the actual issuance of Common Stock or any payment of such consideration upon
the exercise of any such options or rights or the conversion or exchange of such
securities.

                              (4)  Upon the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Series A or Series B Preferred Stock, to
the extent in any way affected by or computed using such options, rights or
securities or options or rights related to such securities, shall be recomputed
to reflect the issuance of only the number of shares of Common Stock (and
convertible or exchangeable securities which remain in effect) actually issued
upon the exercise of such options or rights, upon the conversion or exchange of
such securities or upon the exercise of the options or rights related to such
securities.

                              (5)  The number of shares of Common Stock deemed
issued and the consideration deemed paid therefor pursuant to Sections
4(d)(i)(E)(1) and 4(d)(i)(E)(2) shall be appropriately adjusted to reflect any
change, termination or expiration of the type described in either Section
4(d)(i)(E)(3) or 4(d)(i)(E)(4).

                         (F)  No Increased Conversion Price.  Notwithstanding
                              -----------------------------
any other provisions of this Section (4)(d)(i), except to the limited extent
provided for in Sections 4(d)(i)(E)(3) and 4(d)(i)(E)(4), no adjustment of the
Conversion Price pursuant to this Section 4(d)(i) shall have the effect of
increasing the Conversion Price above the Conversion Price in effect immediately
prior to such adjustment.

                   (ii)  Stock Splits and Dividends.  In the event the
                         --------------------------
Corporation should at any time or from time to time after the Purchase Date fix
a record date for the effectuation of a split or subdivision of the outstanding
shares of Common Stock or the determination of holders of Common Stock entitled
to receive a dividend or other distribution payable in additional shares of
Common Stock or other securities or rights convertible into, or entitling the
holder thereof to receive directly or indirectly, additional shares of Common
Stock (hereinafter referred to as "Common Stock Equivalents") without payment of
                                   ------------------------
any consideration by such holder for the additional shares of Common Stock or
the Common Stock Equivalents (including the additional shares of Common Stock
issuable upon conversion or exercise thereof), then, as of such record date (or
the date of such dividend distribution, split or subdivision if no record date
is fixed), the Conversion Price of the Series A and Series B Preferred Stock
shall be appropriately decreased so that the number of shares of Common Stock
issuable on conversion of each share of such series shall be increased in
proportion to such increase of the aggregate of shares of Common Stock
outstanding and those issuable with respect to such Common Stock Equivalents
with the number of shares issuable with respect to Common Stock Equivalents
determined from time to time in the manner provided for deemed issuances in
Section 4(d)(i)(E).

                   (iii) Reverse Stock Splits.  If the number of shares of
                         --------------------
Common Stock outstanding at any time after the Purchase Date is decreased by a
combination of the outstanding shares of Common Stock, then, following the
record date of such combination, the

                                      -8-
<PAGE>

Conversion Price for the Series A and Series B Preferred Stock shall be
appropriately increased so that the number of shares of Common Stock issuable on
conversion of each share of such series shall be decreased in proportion to such
decrease in outstanding shares.

               (e)  Other Distributions.  In the event the Corporation shall
                    -------------------
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, assets (excluding cash
dividends) or options or rights not referred to in Section 4(d)(ii), then, in
each such case for the purpose of this Section 4(e), the holders of Series A and
Series B Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of the Corporation into which their shares of Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

               (f)  Recapitalizations.  If at any time or from time to time
                    -----------------
there shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or Section 2) provision shall be made so that the holders of the
Series A and Series B Preferred Stock shall thereafter be entitled to receive
upon conversion of such Preferred Stock the number of shares of stock or other
securities or property of the Corporation or otherwise, to which a holder of
Common Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the holders of such Preferred Stock after the recapitalization to the end that
the provisions of this Section 4 (including adjustment of the Conversion Price
then in effect and the number of shares purchasable upon conversion of such
Preferred Stock) shall be applicable after that event and be as nearly
equivalent as practicable.

               (g)  No Impairment.  The Corporation will not, by amendment of
                    -------------
its Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 4 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of Preferred Stock against impairment.

               (h)  No Fractional Shares and Certificate as to Adjustments.
                    ------------------------------------------------------

                    (i) No fractional shares shall be issued upon the conversion
of any share or shares of the Series A or Series B Preferred Stock, and the
number of shares of Common Stock to be issued shall be rounded to the nearest
whole share. The number of shares issuable upon such conversion shall be
determined on the basis of the total number of shares of Series A and Series B
Preferred Stock the holder is at the time converting into Common Stock and the
number of shares of Common Stock issuable upon such aggregate conversion.

                                      -9-
<PAGE>

                    (ii) Upon the occurrence of each adjustment or readjustment
of the Conversion Price of Series A or Series B Preferred Stock pursuant to this
Section 4, the Corporation, at its expense, shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and prepare and
furnish to each holder of such Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Corporation shall, upon the written
request at any time of any holder of Series A or Series B Preferred Stock,
furnish or cause to be furnished to such holder a like certificate setting forth
(A) such adjustment and readjustment, (B) the Conversion Price for the Series A
or Series B Preferred Stock at the time in effect, and (C) the number of shares
of Common Stock and the amount, if any, of other property which at the time
would be received upon the conversion of a share of the Series A or Series B
Preferred Stock.

               (i)  Notices of Record Date.  In the event of any taking by the
                    ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A and Series B Preferred Stock, at least ten
(10) days prior to the date specified therein, a notice specifying the date on
which any such record is to be taken for the purpose of such dividend,
distribution or right, and the amount and character of such dividend,
distribution or right.

               (j)  Reservation of Stock Issuable Upon Conversion.  The
                    ---------------------------------------------
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A and Series B Preferred Stock, such
number of its shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all outstanding shares of such series of Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect the conversion of all then outstanding
shares of such series of Preferred Stock, in addition to such other remedies as
shall be available to the holder of such Preferred Stock, the Corporation will
take such corporate action as may, in the opinion of its counsel, be necessary
to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purposes, including, without limitation,
engaging in best efforts to obtain the requisite shareholder approval of any
necessary amendment to these articles.

               (k)  Notices.  Any notice required by the provisions of this
                    -------
Section 4 to be given to the holders of shares of Series A or Series B Preferred
Stock shall be deemed given if deposited in the United States mail, postage
prepaid, and addressed to each holder of record at his address appearing on the
books of the Corporation.

          5.   Voting Rights.  The holder of each share of Series A and Series B
               -------------
Preferred Stock shall have the right to one vote for each share of Common Stock
into which such Preferred Stock could then be converted, and with respect to
such vote, such holder shall have full voting rights and powers equal to the
voting rights and powers of the holders of Common

                                      -10-
<PAGE>

Stock, and shall be entitled, notwithstanding any provision hereof, to notice of
any shareholders' meeting in accordance with the bylaws of the Corporation, and
shall be entitled to vote, together with holders of Common Stock, with respect
to any question upon which holders of Common Stock have the right to vote.
Fractional votes shall not, however, be permitted and any fractional voting
rights available on an as-converted basis (after aggregating all shares into
which shares of Preferred Stock held by each holder could be converted) shall be
rounded to the nearest whole number (with one-half being rounded upward).

          6.   Protective Provisions.  So long as at least 1,000,000 shares of
               ---------------------
Preferred Stock are outstanding (as adjusted for stock splits, stock dividends
or recapitalizations), the Corporation shall not without first obtaining the
approval (by vote or written consent, as provided by law) of the holders of at
least a majority of the then outstanding shares of Preferred Stock, voting
together as a class:

               (a) effect a transaction described in Section 2(c)(i) above;

               (b) alter or change the rights, preferences or privileges of the
shares of Preferred Stock so as to affect adversely such shares;

               (c) increase the total number of authorized shares of Preferred
Stock;

               (d) authorize or issue any other equity security, including any
other security convertible into or exercisable for any equity security, having a
preference over, or being on a parity with, the Preferred Stock with respect to
voting, dividends, conversion, redemptions or upon liquidation;

               (e) redeem, purchase or otherwise acquire (or pay into or set
funds aside for a sinking fund for such purpose) any share or shares of
Preferred Stock or Common Stock; provided, however, that this restriction shall
                                 --------  -------
not apply to the repurchase of shares of Common Stock from employees, officers,
directors, consultants or other persons performing services for the Corporation
or any subsidiary pursuant to agreements under which the Corporation has the
option to repurchase such shares at cost upon the occurrence of certain events,
such as the termination of such employment or consulting relationship, or
through the exercise of any right of first refusal;

               (f) pay or declare any dividends on Common Stock (other than in
Common Stock of the Company); or

               (g) take any action that would result in the taxation of the
holders of Preferred Stock under Section 305 of the Internal Revenue Code.

          7.   Status of Converted Stock.  In the event any shares of  Preferred
               -------------------------
Stock shall be converted pursuant to Section 4 hereof, the shares so converted
shall be canceled and shall not be issuable by the Corporation.  The Articles of
Incorporation of the Corporation shall be appropriately amended to effect the
corresponding reduction in the Corporation's authorized capital stock.

                                      -11-

          8.   Repurchase of Shares.  In connection with repurchases by the
               --------------------
Corporation of its Common Stock pursuant to its agreements with certain of the
holders thereof, Sections 502 and 503 of the California General Corporation Law
shall not apply in whole or in part with respect to such repurchases.

     (C)  Common Stock.
          ------------

          1.   Dividend Rights.  Subject to the prior rights of holders of all
               ---------------
classes of stock at the time outstanding having prior rights as to dividends,
the holders of the Common Stock shall be entitled to receive, when and as
declared by the Board of Directors, out of any assets of the Corporation legally
available therefor, such dividends as may be declared from time to time by the
Board of Directors.

          2.   Liquidation Rights.  Upon the liquidation, dissolution or winding
               ------------------
up of the Corporation, the assets of the Corporation shall be distributed as

     (C)  Any amendment or repeal or modification of the foregoing provisions of

affect any right or protection of a director of the Corporation existing at the
time of such repeal or modification."

                                 *     *     *

     3.   The foregoing amendment has been approved by the Board of Directors of
this corporation.

     4.   The foregoing amendment was approved by the holders of the requisite

     (A) Classes of Stock.  The Corporation is authorized to issue two classes
         ----------------
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
                                          ------------       ---------------
The total number of shares which the Corporation is authorized to issue is
Twenty Six Million Nine Hundred Thousand (26,900,000) shares, each with a par
value of $0.001 per share.  Twenty Two Million Two Hundred Thousand (22,200,000)
shares shall be Common Stock and Four Million Seven Hundred Thousand (4,700,000)
shares shall be Preferred Stock.

     (B) Rights, Preferences and Restrictions of Preferred Stock.  The Preferred
         -------------------------------------------------------
Stock authorized by this Amended and Restated Certificate of Incorporation (the
"Restated
<PAGE>

Certificate") may be issued from time to time in one or more series. The first
series of Preferred Stock shall be designated "Series A Preferred Stock" and
                                               ------------------------
shall consist of One Million Two Hundred Eight Thousand Six Hundred (1,208,600)
shares. The second series of Preferred Stock shall be designated "Series B
                                                                  --------
Preferred Stock" and shall consist of Three Million Four Hundred Thousand
- ---------------
(3,400,000) shares. The rights, preferences, privileges, and restrictions
granted to and imposed on the Series A and Series B Preferred Stock are as set
forth below in this Article IV(B).

          1.  Dividend Provisions.  The holders of shares of Series A and Series
              -------------------
B Preferred Stock shall be entitled to receive dividends, out of any assets
legally available therefor, prior and in preference to any declaration or
payment of any dividend (payable other than in Common Stock or other securities
and rights convertible into or entitling the holder thereof to receive, directly
or indirectly, additional shares of Common Stock of the Corporation) on the
Common Stock of the Corporation, at the rate of (i) $0.20 per share per annum on
each outstanding share of Series A Preferred Stock (as adjusted for stock
splits, stock dividends or recapitalizations and the like with respect to such
shares) and (ii) $0.52 per share per annum on each outstanding share of Series B
Preferred Stock (as adjusted for stock splits, stock dividends or
recapitalizations and the like with respect to such shares), in each case
payable quarterly when, as and if declared by the Board of Directors.  Such
dividends shall not be cumulative.

          2.  Liquidation.
              -----------

              (a) Preference.  In the event of any liquidation, dissolution or
                  ----------
winding up of the Corporation, either voluntary or involuntary, the holders of
the Series A and Series B Preferred Stock shall be entitled to receive, prior
and in preference to any distribution of any of the assets of the Corporation to
the holders of Common Stock by reason of their ownership thereof, an amount per
share equal to (i) $2.50 per share for each outstanding share of Series A
Preferred Stock then held by them (the "Original Series A Issue Price") and (ii)
$6.50 per share for each outstanding share of Series B Preferred Stock then held
by them (the "Original Series B Issue Price"), plus declared but unpaid
dividends on such share (subject to adjustment of such fixed dollar amounts for
any stock splits, stock dividends, combination, recapitalizations or the like).
If, upon the occurrence of such event, the assets and funds thus distributed
among the holders of the Series A and Series B Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, the entire assets and funds of the Corporation
legally available for distribution shall be distributed ratably among the
holders of the Series A and Series B Preferred Stock in proportion to the
preferential amount each such holder is otherwise entitled to receive.

              (b) Remaining Assets.  Upon the completion of the distribution
                   ----------------
required by subsection (a) of this Section 2, all of the remaining assets of the
Corporation available for distribution to shareholders shall be distributed
among the holders of the Common Stock pro rata based on the number of shares of
Common Stock held by each.

              (c) Certain Acquisitions.
                  --------------------

                  (i) Deemed Liquidation.  For purposes of this Section 2, a
                      ------------------
liquidation, dissolution or winding up of the Corporation shall be deemed to
occur if the
<PAGE>

Corporation shall sell, convey, or otherwise dispose of all or substantially all
of its property or business or merge into or consolidate with any other
corporation (other than a wholly-owned subsidiary corporation) or effect any
other transaction or series of related transactions in which the shareholders of
the Corporation immediately prior thereto own less than a majority of
outstanding shares of voting stock of the Corporation (or its successor or
parent) immediately thereafter, provided that this Section 2(c)(i) shall not
                                --------
apply to a merger effected solely for the purpose of changing the domicile of
the Corporation.

                    (ii)  Valuation of Consideration. In the event of a deemed
                          --------------------------
liquidation as described in Section 2(c)(i) above, if the consideration received
by the Corporation is other than cash, its value will be deemed its fair market
value. Any securities shall be valued as follows:

                          (A)  Securities not subject to investment letter or
other similar restrictions on free marketability:

                               (1)  If traded on a securities exchange or The
Nasdaq National Market, the value shall be deemed to be the average of the
closing sale prices of the securities on such exchange over the thirty-day
period ending three (3) days prior to the closing;

                               (2)  If actively traded over-the-counter other
than through The Nasdaq National Market, the value shall be deemed to be the
average of the closing bid or sale prices (whichever is applicable) over the
thirty-day period ending three (3) days prior to the closing; and

                               (3)  If there is no active public market, the
value shall be the fair market value thereof, as determined in good faith by the
Board of Directors of the Corporation.

                          (B)  The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in Section 2(c)(ii)(A) to reflect the approximate fair
market value thereof, as mutually determined in good faith by the Board of
Directors of the Corporation and the holders of a majority of the shares of
Preferred Stock outstanding.

                    (iii) Notice of Transaction.  The Corporation shall give
                          ---------------------
each holder of record of Series A and Series B Preferred Stock written notice of
a transaction described in 2(c)(i) not later than ten (10) days prior to the
shareholders' meeting called to approve such transaction, or ten (10) days prior
to the closing of such transaction, whichever is earlier, and shall also notify
such holders in writing of the final approval of such transaction. The first of
such notices shall describe the material terms and conditions of the impending
transaction and the provisions of this Section 2, and the Corporation shall
thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place
<PAGE>

sooner than ten (10) days after the Corporation has given the first notice
provided for herein or sooner than ten (10) days after the Corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened upon the written consent of the holders of Preferred
Stock that are entitled to such notice rights or similar notice rights and that
represent at least a majority of the voting power of all then outstanding shares
of such Preferred Stock.

                    (iv) Effect of Noncompliance.  In the event the requirements
                         -----------------------
of this Section 2(c) are not complied with, the Corporation shall forthwith
either cause the closing of the transaction to be postponed until such
requirements have been complied with, or cancel such transaction, in which event
the rights, preferences and privileges of the holders of the Series A and Series
B Preferred Stock shall revert to and be the same as such rights, preferences
and privileges existing immediately prior to the date of the first notice
referred to in Section 2(c)(iii) hereof.

          3.   Redemption.  The Preferred Stock is not redeemable.
               ----------

          4.   Conversion.  The holders of the Series A and Series B Preferred
               ----------
Stock shall have conversion rights as follows (the "Conversion Rights"):
                                                    -----------------

               (a)  Right to Convert.  Subject to Section 4(c), each share of
                    ----------------
Series A and Series B Preferred Stock shall be convertible, at the option of the
holder thereof, at any time after the date of issuance of such share, at the
office of the Corporation or any transfer agent for such stock, into such number
of fully paid and nonassessable shares of Common Stock as is determined by
dividing (i) $2.50 in the case of the Series A Preferred Stock and (ii) $6.50 in
the case of the Series B Preferred Stock by the Conversion Price applicable to
such share, determined as hereafter provided, in effect on the date the
certificate is surrendered for conversion. The initial Conversion Price per
share shall be $2.50 for shares of Series A Preferred Stock and $6.50 for shares
of Series B Preferred Stock. Such initial Conversion Price shall be subject to
adjustment as set forth in Section 4(d).

               (b)  Automatic Conversion.  Each share of Series A and Series B
                    --------------------
Preferred Stock shall automatically be converted into shares of Common Stock at
the Conversion Price at the time in effect for such share immediately upon the
earlier of (i) except as provided below in Section 4(c), the Corporation's sale
of its Common Stock in a firm commitment underwritten public offering (the
"IPO") pursuant to a registration statement under the Securities Act of 1933, as
 ---
amended (the "Securities Act"), in which the Pre-Money Valuation (as defined
              --------------
below) of the Company is at least $125 million and which results in aggregate
cash proceeds to the Corporation of not less than $15,000,000 (net of
underwriting discounts and commissions) or (ii) the date specified by written
consent or agreement of the holders of two thirds (66 2/3%) of the then
outstanding shares of Preferred Stock, voting as a single class on an as-
converted basis.  Upon such automatic conversion, any declared but unpaid
dividends shall be paid in accordance with Section 4(c). For the purpose of this
subsection the term "Pre-Money Valuation" means the product obtained by
                     -------------------
multiplying (i) the per share public offering price by (ii) the number of shares
of Common Stock outstanding on the date on which the Form S-1 registration
statement
<PAGE>

for the IPO (the "Form S-1") is filed (assuming, for the purpose of calculating
                  --------
such number of shares of Common Stock (1) the conversion of all shares of
Preferred Stock then outstanding, (2) the exercise and conversion of all options
and warrants then outstanding, and (3) the issuance, exercise and conversion of
all shares then reserved for issuance under the Company's stock and option
plans).

               (c)  Mechanics of Conversion.  Before any holder of Series A or
                    -----------------------
Series B Preferred Stock shall be entitled to convert the same into shares of
Common Stock, such holder shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the Corporation or of any transfer
agent for such series of Preferred Stock, and shall give written notice to the
Corporation at its principal corporate office, of the election to convert the
same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. The Corporation shall,
as soon as practicable thereafter, issue and deliver at such office to such
holder of Preferred Stock, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of such series of Preferred Stock to be converted, and
the person or persons entitled to receive the shares of Common Stock issuable
upon such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock as of such date. If the conversion is in
connection with an underwritten offering of securities registered pursuant to
the Securities Act the conversion may, at the option of any holder tendering
such Preferred Stock for conversion, be conditioned upon the closing with the
underwriters of the sale of securities pursuant to such offering, in which event
the person(s) entitled to receive Common Stock upon conversion of such Preferred
Stock shall not be deemed to have converted such Preferred Stock until
immediately prior to the closing of such sale of securities.

               (d)  Conversion Price Adjustments of Preferred Stock for Certain
                    -----------------------------------------------------------
Dilutive Issuances, Splits and Combinations.  The Conversion Price of the Series
- -------------------------------------------
A and Series B Preferred Stock shall be subject to adjustment from time to time
as follows:

                    (i)  Issuance of Additional Stock below Purchase Price.  If
                         -------------------------------------------------
the Corporation shall issue, after the date upon which any shares of Series B
Preferred Stock were first issued (the "Purchase Date"), any Additional Stock
                                        -------------
(as defined below) without consideration or for a consideration per share less
than the Conversion Price for a series in effect immediately prior to the
issuance of such Additional Stock, the Conversion Price for such series in
effect immediately prior to each such issuance shall automatically be adjusted
as set forth in this Section 4(d)(i), unless otherwise provided in this Section
4(d)(i).

                         (A)  Price Adjustment. Whenever the Conversion Price is
                              ----------------
adjusted pursuant to this Section 4(d)(i), the new Conversion Price shall be
determined by multiplying the Conversion Price then in effect by a fraction, (x)
the numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such issuance (the "Outstanding Common") plus the number of
                                         ------------------
shares of Common Stock that the aggregate consideration received by the
Corporation for such issuance would purchase at such Conversion
<PAGE>

Price; and (y) the denominator of which shall be the number of shares of
Outstanding Common plus the number of shares of such Additional Stock. For
purposes of the foregoing calculation, the term "Outstanding Common" shall
include shares of Common Stock deemed issued pursuant to Section 4(d)(i)(E)
below.

                         (B)  Definition of "Additional Stock". For purposes of
                              -------------------------------
this Section 4(d)(i), "Additional Stock" shall mean any shares of Common Stock
                       ----------------
issued (or deemed to have been issued pursuant to Section 4(d)(i)(E)) by the
Corporation after the Purchase Date) other than

                              (1)  Common Stock issued pursuant to a transaction
described in Section 4(d)(ii) hereof,

                              (2)  Shares of Common Stock issuable or issued to
employees, consultants or directors of the Corporation pursuant to restricted
stock purchase or stock option plans or agreements approved by the Board of
Directors of the Corporation,

                              (3)  Capital stock, or options or warrants to
purchase capital stock, issued to financial institutions or other lenders or
lessors in connection with loans, leases, equipment financings or similar
transactions,

                              (4)  Shares of Common Stock or Preferred Stock
issuable upon exercise of warrants outstanding as of the date of these Amended
and Restated Certificate of Incorporation (and issuable on the conversion of
shares issuable upon such exercise),

                              (5)  Capital stock or warrants or options to
purchase capital stock issued in connection with bona fide acquisitions, mergers
or similar transactions, the terms of which are approved by the Board of
Directors of the Corporation,

                              (6) Shares of Common Stock issued or issuable upon
conversion of the Series A or Series B Preferred Stock,

                              (7)  Shares of Common Stock issued or issuable in
a public offering prior to or in connection with which all outstanding shares of
Preferred Stock will be converted to Common Stock, and

                              (8)  Securities issued in connection with research
and development partnerships, licensing or collaborative arrangements and
similar transactions approved by the Board of Directors of the Corporation.

                         (C)  No Fractional Adjustments.  No adjustment of the
                              -------------------------
Conversion Price for the Series A or Series B Preferred Stock shall be made in
an amount less than one cent per share, provided that any adjustments which are
not required to be made by reason of this sentence shall be carried forward and
shall be either taken into account in any subsequent adjustment made prior to
three years from the date of the event giving rise to the
<PAGE>

adjustment being carried forward, or shall be made at the end of three years
from the date of the event giving rise to the adjustment being carried forward.

                         (D)  Determination of Consideration.  In the case of
                              ------------------------------
the issuance of Common Stock for cash, the consideration shall be deemed to be
the amount of cash paid therefor before deducting any reasonable discounts,
commissions or other expenses allowed, paid or incurred by the Corporation for
any underwriting or otherwise in connection with the issuance and sale thereof.
In the case of the issuance of the Common Stock for a consideration in whole or
in part other than cash, the consideration other than cash shall be deemed to be
the fair value thereof as determined by the Board of Directors irrespective of
any accounting treatment.

                         (E)  Deemed Issuances of Common Stock.  In the case of
                              --------------------------------
the issuance (whether before, on or after the Purchase Date) of options to
purchase or rights to subscribe for Common Stock, securities by their terms
convertible into or exchangeable for Common Stock or options to purchase or
rights to subscribe for such convertible or exchangeable securities, the
following provisions shall apply for all purposes of this Section 4(d)(i):

                              (1)  The aggregate maximum number of shares of
Common Stock deliverable upon exercise (assuming the satisfaction of any
conditions to exercisability, including without limitation, the passage of time,
but without taking into account potential antidilution adjustments) of such
options to purchase or rights to subscribe for Common Stock shall be deemed to
have been issued at the time such options or rights were issued and for a
consideration equal to the consideration (determined in the manner provided in
Section 4(d)(i)(D)), if any, received by the Corporation upon the issuance of
such options or rights plus the minimum exercise price provided in such options
or rights (without taking into account potential antidilution adjustments) for
the Common Stock covered thereby.

                              (2)  The aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange (assuming the
satisfaction of any conditions to convertibility or exchangeability, including,
without limitation, the passage of time, but without taking into account
potential antidilution adjustments) for any such convertible or exchangeable
securities or upon the exercise of options to purchase or rights to subscribe
for such convertible or exchangeable securities and subsequent conversion or
exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal
to the consideration, if any, received by the Corporation for any such
securities and related options or rights (excluding any cash received on account
of accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Corporation (without taking into
account potential antidilution adjustments) upon the conversion or exchange of
such securities or the exercise of any related options or rights (the
consideration in each case to be determined in the manner provided in Section
4(d)(i)(D).

                              (3)  In the event of any change in the number of
shares of Common Stock deliverable or in the consideration payable to the
Corporation upon exercise of such options or rights or upon conversion of or in
exchange for such convertible or
<PAGE>

exchangeable securities, including, but not limited to, a change resulting from
the antidilution provisions thereof, the Conversion Price of the Series A or the
Series B Preferred Stock, to the extent in any way affected by or computed using
such options, rights or securities, shall be recomputed to reflect such change,
but no further adjustment shall be made for the actual issuance of Common Stock
or any payment of such consideration upon the exercise of any such options or
rights or the conversion or exchange of such securities.

                              (4)  Upon the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Series A or Series B Preferred Stock, to
the extent in any way affected by or computed using such options, rights or
securities or options or rights related to such securities, shall be recomputed
to reflect the issuance of only the number of shares of Common Stock (and
convertible or exchangeable securities which remain in effect) actually issued
upon the exercise of such options or rights, upon the conversion or exchange of
such securities or upon the exercise of the options or rights related to such
securities.

                              (5)  The number of shares of Common Stock deemed
issued and the consideration deemed paid therefor pursuant to Sections
4(d)(i)(E)(1) and 4(d)(i)(E)(2) shall be appropriately adjusted to reflect any
change, termination or expiration of the type described in either Section
4(d)(i)(E)(3) or 4(d)(i)(E)(4).

                         (F)  No Increased Conversion Price.  Notwithstanding
                              -----------------------------
any other provisions of this Section (4)(d)(i), except to the limited extent
provided for in Sections 4(d)(i)(E)(3) and 4(d)(i)(E)(4), no adjustment of the
Conversion Price pursuant to this Section 4(d)(i) shall have the effect of
increasing the Conversion Price above the Conversion Price in effect immediately
prior to such adjustment.

                    (ii) Stock Splits and Dividends.  In the event the
                         --------------------------
Corporation should at any time or from time to time after the Purchase Date fix
a record date for the effectuation of a split or subdivision of the outstanding
shares of Common Stock or the determination of holders of Common Stock entitled
to receive a dividend or other distribution payable in additional shares of
Common Stock or other securities or rights convertible into, or entitling the
holder thereof to receive directly or indirectly, additional shares of Common
Stock (hereinafter referred to as "Common Stock Equivalents") without payment of
                                   ------------------------
any consideration by such holder for the additional shares of Common Stock or
the Common Stock Equivalents (including the additional shares of Common Stock
issuable upon conversion or exercise thereof), then, as of such record date (or
the date of such dividend distribution, split or subdivision if no record date
is fixed), the Conversion Price of the Series A and Series B Preferred Stock
shall be appropriately decreased so that the number of shares of Common Stock
issuable on conversion of each share of such series shall be increased in
proportion to such increase of the aggregate of shares of Common Stock
outstanding and those issuable with respect to such Common Stock Equivalents
with the number of shares issuable with respect to Common Stock Equivalents
determined from time to time in the manner provided for deemed issuances in
Section 4(d)(i)(E).
<PAGE>

                    (iii)  Reverse Stock Splits.  If the number of shares of
                           --------------------
Common Stock outstanding at any time after the Purchase Date is decreased by a
combination of the outstanding shares of Common Stock, then, following the
record date of such combination, the Conversion Price for the Series A and
Series B Preferred Stock shall be appropriately increased so that the number of
shares of Common Stock issuable on conversion of each share of such series shall
be decreased in proportion to such decrease in outstanding shares.

               (e)  Other Distributions.  In the event the Corporation shall
                    -------------------
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, assets (excluding cash
dividends) or options or rights not referred to in Section 4(d)(ii), then, in
each such case for the purpose of this Section 4(e), the holders of Series A and
Series B Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of the Corporation into which their shares of Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of the Corporation entitled to receive such distribution.

               (f)  Recapitalizations.  If at any time or from time to time
                    -----------------
there shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or Section 2) provision shall be made so that the holders of the
Series A and Series B Preferred Stock shall thereafter be entitled to receive
upon conversion of such Preferred Stock the number of shares of stock or other
securities or property of the Corporation or otherwise, to which a holder of
Common Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the holders of such Preferred Stock after the recapitalization to the end that
the provisions of this Section 4 (including adjustment of the Conversion Price
then in effect and the number of shares purchasable upon conversion of such
Preferred Stock) shall be applicable after that event and be as nearly
equivalent as practicable.

               (g)  No Impairment.  The Corporation will not, by amendment of
                    -------------
its Certificate of Incorporation or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all
such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of Preferred Stock against impairment.

               (h)  No Fractional Shares and Certificate as to Adjustments.
                    ------------------------------------------------------

                    (i)  No fractional shares shall be issued upon the
conversion of any share or shares of the Series A or Series B Preferred Stock,
and the number of shares of Common Stock to be issued shall be rounded to the
nearest whole share. The number of shares issuable upon such conversion shall be
determined on the basis of the total number of shares of
<PAGE>

Series A and Series B Preferred Stock the holder is at the time converting into
Common Stock and the number of shares of Common Stock issuable upon such
aggregate conversion.

                    (ii) Upon the occurrence of each adjustment or readjustment
of the Conversion Price of Series A or Series B Preferred Stock pursuant to this
Section 4, the Corporation, at its expense, shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and prepare and
furnish to each holder of such Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such
adjustment or readjustment is based. The Corporation shall, upon the written
request at any time of any holder of Series A or Series B Preferred Stock,
furnish or cause to be furnished to such holder a like certificate setting forth
(A) such adjustment and readjustment, (B) the Conversion Price for the Series A
or Series B Preferred Stock at the time in effect, and (C) the number of shares
of Common Stock and the amount, if any, of other property which at the time
would be received upon the conversion of a share of the Series A or Series B
Preferred Stock.

               (i)  Notices of Record Date.  In the event of any taking by the
                    ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A and Series B Preferred Stock, at least ten
(10) days prior to the date specified therein, a notice specifying the date on
which any such record is to be taken for the purpose of such dividend,
distribution or right, and the amount and character of such dividend,
distribution or right.

               (j)  Reservation of Stock Issuable Upon Conversion.  The
                    ---------------------------------------------
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A and Series B Preferred Stock, such
number of its shares of Common Stock as shall from time to time be sufficient to
effect the conversion of all outstanding shares of such series of Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock shall not be sufficient to effect the conversion of all then outstanding
shares of such series of Preferred Stock, in addition to such other remedies as
shall be available to the holder of such Preferred Stock, the Corporation will
take such corporate action as may, in the opinion of its counsel, be necessary
to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purposes, including, without limitation,
engaging in best efforts to obtain the requisite shareholder approval of any
necessary amendment to this certificate.

               (k)  Notices.  Any notice required by the provisions of this
                    -------
Section 4 to be given to the holders of shares of Series A or Series B Preferred
Stock shall be deemed given if deposited in the United States mail, postage
prepaid, and addressed to each holder of record at his address appearing on the
books of the Corporation.
<PAGE>

          5.   Voting Rights.  The holder of each share of Series A and Series B
               -------------
Preferred Stock shall have the right to one vote for each share of Common Stock
into which such Preferred Stock could then be converted, and with respect to
such vote, such holder shall have full voting rights and powers equal to the
voting rights and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any shareholders' meeting in
accordance with the bylaws of the Corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote.  Fractional votes shall not,
however, be permitted and any fractional voting rights available on an as-
converted basis (after aggregating all shares into which shares of Preferred
Stock held by each holder could be converted) shall be rounded to the nearest
whole number (with one-half being rounded upward).

          6.   Protective Provisions.  So long as at least 1,000,000 shares of
               ---------------------
Preferred Stock are outstanding (as adjusted for stock splits, stock dividends
or recapitalizations), the Corporation shall not without first obtaining the
approval (by vote or written consent, as provided by law) of the holders of at
least a majority of the then outstanding shares of Preferred Stock, voting
together as a class:

               (a) effect a transaction described in Section 2(c)(i) above;

               (b) alter or change the rights, preferences or privileges of the
shares of Preferred Stock so as to affect adversely such shares;

               (c) increase the total number of authorized shares of Preferred
Stock;

               (d) authorize or issue any other equity security, including any
other security convertible into or exercisable for any equity security, having a
preference over, or being on a parity with, the Preferred Stock with respect to
voting, dividends, conversion, redemptions or upon liquidation;

               (e) redeem, purchase or otherwise acquire (or pay into or set
funds aside for a sinking fund for such purpose) any share or shares of
Preferred Stock or Common Stock; provided, however, that this restriction shall
                                 --------  -------
not apply to the repurchase of shares of Common Stock from employees, officers,
directors, consultants or other persons performing services for the Corporation
or any subsidiary pursuant to agreements under which the Corporation has the
option to repurchase such shares at cost upon the occurrence of certain events,
such as the termination of such employment or consulting relationship, or
through the exercise of any right of first refusal;

               (f) pay or declare any dividends on Common Stock (other than in
Common Stock of the Company); or

               (g) take any action that would result in the taxation of the
holders of Preferred Stock under Section 305 of the Internal Revenue Code.
<PAGE>

     (C)  Common Stock.
          ------------

          1.  Dividend Rights.  Subject to the prior rights of holders of all
              ---------------
classes of stock at the time outstanding having prior rights as to dividends,
the holders of the Common Stock shall be entitled to receive, when and as
declared by the Board of Directors, out of any assets of the Corporation legally
available therefor, such dividends as may be declared from time to time by the
Board of Directors.

          2.  Liquidation Rights.  Upon the liquidation, dissolution or winding
              ------------------
up of the Corporation, the assets of the Corporation shall be distributed as
provided in Section 2 of Division (B) of this Article IV.

          3.  Redemption.  The Common Stock is not redeemable.
              ----------

          4.  Voting Rights.  The holder of each share of Common Stock shall
              -------------
have the right to one vote, and shall be entitled to notice of any shareholders'
meeting in accordance with the bylaws of the Corporation, and shall be entitled
to vote upon such matters and in such manner as may be provided by law.

     3.  The Certificate of Incorporation of this corporation shall be amended

                                                             -----------

     The purpose of the Corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of
Delaware.

                                   ARTICLE IV

     (A) Classes of Stock.  The Corporation is authorized to issue two classes
         ----------------
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
                                          ------------       ---------------
The total number of shares which the Corporation is authorized to issue is
105,000,000 shares, each with a par value of $0.001 per share. 100,000,000 of
such shares shall be Common Stock, and 5,000,000 of such shares shall be
Preferred Stock.

     (B) The Preferred Stock may be issued from time to time in one or more

<PAGE>

number of shares constituting any such series and the designation thereof, or
any of them; and to increase or decrease the number of shares of any series
subsequent to the issuance of shares of that series, but not below the number of
shares of such series then outstanding. In case the number of shares of any
series shall be so decreased, the shares constituting such decrease shall resume
the status which they had prior to the adoption of the resolution originally
fixing the number of shares of such series.


                                   ARTICLE V

     The number of directors of the Corporation shall be fixed from time to time
by a bylaw or amendment thereof duly adopted by the Board of Directors.


                                   ARTICLE VI

     "Listing Event" as used in this Amended and Restated Certificate of
      -------------
Incorporation shall mean the first annual meeting of stockholders following such
time as the Corporation meets the criteria set forth in subdivisions (1), (2) or
(3) of Section 2115(c) the California Corporations Code as of the record date of
such meeting.

     For the management of the business and for the conduct of the affairs of
the Corporation, and in further definition, limitation and regulation of the
powers of the Corporation, its directors and its stockholders or any class
thereof, as the case may be, it is further provided that, effective upon the
occurrence of the Listing Event:

          (i) The number of directors which shall constitute the entire Board of
Directors, and the number of directors in each class, shall be fixed exclusively
by one or more resolutions adopted from time to time by the Board of Directors.
The Board of Directors shall be divided into three classes, designated as Class
I, Class II and Class III, respectively.  Directors shall be assigned to each
class in accordance with a resolution or resolutions adopted by the Board of
Directors.  Until changed by a resolution of the Board of Directors, Class I
shall consist of three directors, each of whom shall be designated by the Board
of Directors; Class II shall consist of three directors, each of whom shall be
designated by the Board of Directors; and Class III shall consist of three
directors, each of whom shall be designated by the Board of Directors.

          Upon the occurrence of the Listing Event, the terms of office of the
Class I directors shall expire, and Class I directors shall be elected for a
full term of three years.  At the first annual meeting of stockholders following
the Listing Event, the term of office of the Class II directors shall expire,
and Class II directors shall be elected for a full term of three years. At the
second annual meeting of stockholders following the Listing Event, the term of
office of the Class III directors shall expire, and Class III directors shall be
elected for a full term of three years.  At each succeeding annual meeting of
stockholders, directors shall be elected for a full term of three years to
succeed the directors of the class whose terms expire at such annual meeting.

          Any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal, or other causes shall be filled by
either (i) the affirmative vote of the

                                      -2-
<PAGE>

holders of a majority of the voting power of the then-outstanding shares of
voting stock of the corporation entitled to vote generally in the election of
directors (the "Voting Stock") voting together as a single class; or (ii) by the
                ------------
affirmative vote of a majority of the remaining directors then in office, even
though less than a quorum of the Board of Directors. Newly created directorships
resulting from any increase in the number of directors shall, unless the Board
of Directors determines by resolution that any such newly created directorship
shall be filled by the stockholders, be filled only by the affirmative vote of
the directors then in office, even though less than a quorum of the Board of
Directors. Any director elected in accordance with the preceding sentence shall
hold office for the remainder of the full term of the class of directors in
which the new directorship was created or the vacancy occurred and until such
director's successor shall have been elected and qualified.

          In addition to the requirements of law and any other provisions hereof
(and notwithstanding the fact that approval by a lesser vote may be permitted by
law or any other provision hereof), the affirmative vote of the holders of at
least 66 2/3 percent of the voting power of the then outstanding shares of stock
of all classes and all series of the Corporation entitled to vote generally in
the election of directors, voting together as a single class, shall be required
to amend, alter, repeal, or adopt any provision inconsistent with this Section
(i) of this Article VI.

          (ii) There shall be no right with respect to shares of stock of the
Corporation to cumulate votes in the election of directors.

          (iii)  Any director, or the entire Board of Directors, may be removed
from office at any time (i) with cause by the affirmative vote of the holders of
at least a majority of the voting power of the then-outstanding shares of the
Voting Stock, voting together as a single class; or (ii) without cause by the
affirmative vote of the holders of at least 66-2/3% of the voting power of the
then-outstanding shares of the Voting Stock.


                                  ARTICLE VII

     No action shall be taken by the stockholders of the Corporation other than
at an annual or special meeting of the stockholders, upon due notice and in
accordance with the provisions of the Corporation's bylaws.


                                  ARTICLE VIII

     The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Amended and Restated Certificate of Incorporation,
in the manner now or hereafter prescribed by statute, and all rights conferred
upon stockholders herein are granted subject to this reservation.

     Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide. The books of the Corporation may be kept

Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of the Corporation.


                                   ARTICLE XI

     The Corporation shall have perpetual existence.


                                  ARTICLE XII

     (A) To the fullest extent permitted by the General Corporation Law of
Delaware, as the same may be amended from time to time, a director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director.
If the General Corporation Law of Delaware is hereafter amended to authorize,
with the approval of a corporation's stockholders, further reductions in the
liability of the Corporation's directors for breach of fiduciary duty, then a
director of the Corporation shall not be liable for any such breach to the
fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     (B) Any repeal or modification of the foregoing provisions of this Article
XII shall not adversely affect any right or protection of a director of the
Corporation with respect to any acts or omissions of such director occurring
prior to such repeal or modification.


                                  ARTICLE XIII

     (A) To the fullest extent permitted by applicable law, the Corporation is
also authorized to provide indemnification of (and advancement of expenses to)
such agents (and any other persons to which Delaware law permits the Corporation
to provide indemnification) though bylaw provisions, agreements with such agents
or other persons, vote of stockholders or disinterested directors or otherwise,
in excess of the indemnification and advancement otherwise permitted by Section
145 of the Delaware General Corporation Law, subject only to limits created by
applicable Delaware law (statutory or non-statutory), with respect to actions
for breach of duty to a corporation, its stockholders, and others.

     (B) Any repeal or modification of any of the foregoing provisions of this
Article XIII shall not adversely affect any right or protection of a director,
officer, agent or other person existing at the time of, or increase the
liability of any director of the Corporation with respect to any acts or
omissions of such director, officer or agent occurring prior to such repeal or
modification."

or more persons (determined as provided in Section 605 of the Code) on the
record date for the shareholders' meeting, or (iv) by telegraphic or other
written communication.  Notices not personally delivered shall be sent charges
prepaid and shall be addressed to the shareholder at the address of that
shareholder appearing on the books of the corporation or given by the
shareholder to the corporation for the purpose of notice.  If no such address
appears on the corporation's books or is given, notice shall be deemed to have
been given if sent to that shareholder by mail or telegraphic or other written
communication to the corporation's principal executive office, or if published
at least once in a newspaper of general circulation in the county where that
office is located.  Notice shall be deemed to have been given at the time when
delivered personally or deposited in the mail or sent by telegram or other means
of written communication.

          If any notice addressed to a shareholder at the address of that
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at that address, then all future notices or reports shall be deemed to have been
duly given without further mailing if the same shall be available to the
shareholder on written demand of the shareholder at the principal executive
office of the corporation for a period of one (1) year from the date of the
giving of the notice.

          An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

     2.6  Quorum.
          ------

          The presence in person or by proxy of the holders of a majority of the
shares entitled to vote thereat constitutes a quorum for the transaction of
business at all meetings of shareholders.  The shareholders present at a duly
called or held meeting at which a quorum is present may continue to do business
until adjournment, notwithstanding the withdrawal of enough shareholders to
leave less than a quorum, if any action taken (other than adjournment) is
approved by at least a majority of the shares required to constitute a quorum.

     2.7  Adjourned Meeting; Notice.
          -------------------------

          Any shareholders' meeting, annual or special, whether or not a quorum
is present, may be adjourned from time to time by the vote of the majority of
the shares represented at that meeting, either in person or by proxy.  In the
absence of a quorum, no other business may be transacted at that meeting except
as provided in Section 2.6 of these bylaws.

          When any meeting of shareholders, either annual or special, is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place are

                                      -3-
<PAGE>

announced at the meeting at which the adjournment is taken. However, if a new
record date for the adjourned meeting is fixed or if the adjournment is for more
than forty-five (45) days from the date set for the original meeting, then
notice of the adjourned meeting shall be given. Notice of any such adjourned
meeting shall be given to each shareholder of record entitled to vote at the
adjourned meeting in accordance with the provisions of Sections 2.4 and 2.5 of
these bylaws. At any adjourned meeting the corporation may transact any business
which might have been transacted at the original meeting.

     2.8  Voting.
          ------

          The shareholders entitled to vote at any meeting of shareholders shall
be determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 702 through 704 of the Code (relating to
voting shares held by a fiduciary, in the name of a corporation or in joint
ownership).

          The shareholders' vote may be by voice vote or by ballot; provided,
however, that any election for directors must be by ballot if demanded by any
shareholder at the meeting and before the voting has begun.

          Except as provided in the last paragraph of this Section 2.8, or as
may be otherwise provided in the articles of incorporation, each outstanding
share, regardless of class, shall be entitled to one vote on each matter
submitted to a vote of the shareholders.  Any shareholder entitled to vote on
any matter may vote part of the shares in favor of the proposal and refrain from
voting the remaining shares or, except when the matter is the election of
directors, may vote them against the proposal; but, if the shareholder fails to
specify the number of shares which the shareholder is voting affirmatively, it
will be conclusively presumed that the shareholder's approving vote is with
respect to all shares which the shareholder is entitled to vote.

          If a quorum is present, the affirmative vote of the majority of the
shares represented and voting at a duly held meeting (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or a vote by
classes is required by the Code or by the articles of incorporation.

          At a shareholders' meeting at which directors are to be elected, a
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes which such shareholder normally
is entitled to cast) if the candidates' names have been placed in nomination
prior to commencement of the voting and the shareholder has given notice prior
to commencement of the voting of the shareholder's intention to cumulate votes.
If any shareholder has given such a notice, then every shareholder entitled to
vote may cumulate votes for candidates in nomination either (i) by giving one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which that shareholder's shares are
normally entitled or (ii) by distributing the shareholder's votes on the same
principle among any or all of the candidates, as the shareholder thinks fit.
The candidates receiving the highest number of affirmative votes, up to the
number of directors to be elected, shall be elected; votes against any candidate
and votes withheld shall have no legal effect.

     2.9  Validation Of Meetings; Waiver Of Notice; Consent.
          -------------------------------------------------

          The transactions of any meeting of shareholders, either annual or
special, however called and noticed, and wherever held, shall be as valid as
though taken at a meeting duly held after regular call and notice, if a quorum
is present either in person or by proxy, and if, either before or after the
meeting, each person entitled to vote, who was not present in person or by
proxy, signs a written waiver of notice or a consent to the holding of the
meeting or an approval of the minutes thereof.  The waiver of notice or consent
or approval need not specify either the business to be transacted or the purpose
of any annual or special meeting of shareholders, except that if action is taken
or proposed to be taken for approval of any of those matters specified in the
second paragraph of Section 2.4 of these bylaws, the waiver of notice or consent
or approval shall state the general nature of the proposal.  All such waivers,
consents, and approvals shall be filed with the corporate records or made a part
of the minutes of the meeting.

          Attendance by a person at a meeting shall also constitute a waiver of
notice of and presence at that meeting, except when the person objects at the
beginning of the meeting to the transaction of any business because the meeting
is not lawfully called or convened.  Attendance at a meeting is not a waiver of
any right to object to the consideration of matters required by the Code to be
included in the notice of the meeting but not so included, if that objection is
expressly made at the meeting.

     2.10 Shareholder Action By Written Consent Without A Meeting.
          -------------------------------------------------------

          Any action which may be taken at any annual or special meeting of
shareholders may be taken without a meeting and without prior notice, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take that action at a meeting at which all
shares entitled to vote on that action were present and voted.

          In the case of election of directors, such a consent shall be
effective only if signed by the holders of all outstanding shares entitled to
vote for the election of directors.  However, a director may be elected at any
time to fill any vacancy on the Board of Directors, provided that it was not
created by removal of a director and that it has not been filled by the
directors, by the written consent of the holders of a majority of the
outstanding shares entitled to vote for the election of directors.

          All such consents shall be maintained in the corporate records.  Any
shareholder giving a written consent, or the shareholder's proxy holders, or a
transferee of the shares, or a personal representative of the shareholder, or
their respective proxy holders, may revoke the consent by a writing received by
the secretary of the corporation before written consents of the number of shares
required to authorize the proposed action have been filed with the secretary.

          If the consents of all shareholders entitled to vote have not been
solicited in writing and if the unanimous written consent of all such
shareholders has not been received, then the secretary shall give prompt notice
of the corporate action approved by the shareholders without a meeting.  Such
notice shall be given to those shareholders entitled to vote who have

                                      -5-
<PAGE>

not consented in writing and shall be given in the manner specified in Section
2.5 of these bylaws. In the case of approval of (i) a contract or transaction in
which a director has a direct or indirect financial interest, pursuant to
Section 310 of the Code, (ii) indemnification of a corporate "agent," pursuant
to Section 317 of the Code, (iii) a reorganization of the corporation, pursuant
to Section 1201 of the Code, or (iv) a distribution in dissolution other than in
accordance with the rights of outstanding preferred shares, pursuant to Section
2007 of the Code, the notice shall be given at least ten (10) days before the
consummation of any action authorized by that approval.

     2.11 Record Date For Shareholder Notice, Voting, Or Giving Consents.
          --------------------------------------------------------------

          For purposes of determining the shareholders entitled to notice of any
meeting or to vote thereat or entitled to give consent to corporate action
without a meeting, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty (60) days nor less than ten (10) days before
the date of any such meeting nor more than sixty (60) days before any such
action without a meeting, and in such event only shareholders of record on the
date so fixed are entitled to notice and to vote or to give consents, as the
case may be, notwithstanding any transfer of any shares on the books of the
corporation after the record date, except as otherwise provided in the Code.

          If the Board of Directors does not so fix a record date:

          (a) the record date for determining shareholders entitled to notice of
or to vote at a meeting of shareholders shall be at the close of business on the
business day next preceding the day on which notice is given or, if notice is
waived, at the close of business on the business day next preceding the day on
which the meeting is held; and

          (b) the record date for determining shareholders entitled to give
consent to corporate action in writing without a meeting, (i) when no prior
action by the board has been taken, shall be the day on which the first written
consent is given, or (ii) when prior action by the board has been taken, shall
be at the close of business on the day on which the board adopts the resolution
relating to that action, or the sixtieth (60th) day before the date of such
other action, whichever is later.

          The record date for any other purpose shall be as provided in Article
VIII of these bylaws.

     2.12 Proxies.
          -------

          Every person entitled to vote for directors, or on any other matter,
shall have the right to do so either in person or by one or more agents
authorized by a written proxy signed by the person and filed with the secretary
of the corporation.  A proxy shall be deemed signed if the shareholder's name is
placed on the proxy (whether by manual signature, typewriting, telegraphic
transmission or otherwise) by the shareholder or the shareholder's attorney-in-
fact.  A validly executed proxy which does not state that it is irrevocable
shall continue in full force and effect unless (i) the person who executed the
proxy revokes it prior to the time of voting by delivering a writing to the
corporation stating that the proxy is revoked or by executing a subsequent proxy

                                      -6-
<PAGE>

and presenting it to the meeting or by voting in person at the meeting, or (ii)
written notice of the death or incapacity of the maker of that proxy is received
by the corporation before the vote pursuant to that proxy is counted; provided,
however, that no proxy shall be valid after the expiration of eleven (11) months
from the date of the proxy, unless otherwise provided in the proxy.  The dates
contained on the forms of proxy presumptively determine the order of execution,
regardless of the postmark dates on the envelopes in which they are mailed.  The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Sections 705(e) and 705(f) of the Code.

     2.13 Inspectors Of Election.
          ----------------------

          Before any meeting of shareholders, the Board of Directors may appoint
an inspector or inspectors of election to act at the meeting or its adjournment.
If no inspector of election is so appointed, then the chairman of the meeting
may, and on the request of any shareholder or a shareholder's proxy shall,
appoint an inspector or inspectors of election to act at the meeting.  The
number of inspectors shall be either one (l) or three (3).  If inspectors are
appointed at a meeting pursuant to the request of one (l) or more shareholders
or proxies, then the holders of a majority of shares or their proxies present at
the meeting shall determine whether one (l) or three (3) inspectors are to be
appointed.  If any person appointed as inspector fails to appear or fails or
refuses to act, then the chairman of the meeting may, and upon the request of
any shareholder or a shareholder's proxy shall, appoint a person to fill that
vacancy.

          Such inspectors shall:

          (a) determine the number of shares outstanding and the voting power of
each, the number of shares represented at the meeting, the existence of a
quorum, and the authenticity, validity, and effect of proxies;

          (b) receive votes, ballots or consents;

          (c) hear and determine all challenges and questions in any way arising
in connection with the right to vote;

          (d) count and tabulate all votes or consents;

          (e) determine when the polls shall close;

          (f)  determine the result; and

          (g) do any other acts that may be proper to conduct the election or
vote with fairness to all shareholders.

                                  ARTICLE III


                                   DIRECTORS
                                   ---------


     3.1  Powers.
          ------

          Subject to the provisions of the Code and any limitations in the
articles of incorporation and these bylaws relating to actions required to be
approved by the shareholders or by the outstanding shares, the business and
affairs of the corporation shall be managed and all corporate powers shall be
exercised by or under the direction of the Board of Directors.

     3.2  Number Of Directors.
          -------------------

          The number of directors of the corporation shall be not less than
three (3) nor more than five (5).  The exact number of directors shall be three
(3) until changed, within the limits specified above, by a bylaw amending this
Section 3.2, duly adopted by the Board of Directors or by the shareholders.  The
indefinite number of directors may be changed, or a definite number may be fixed
without provision for an indefinite number, by a duly adopted amendment to the
articles of incorporation or by an amendment to this bylaw duly adopted by the
vote or written consent of holders of a majority of the outstanding shares
entitled to vote; provided, however, that an amendment reducing the fixed number
or the minimum number of directors to a number less than five (5) cannot be
adopted if the votes cast against its adoption at a meeting, or the shares not
consenting in the case of an action by written consent, are equal to more than
sixteen and two-thirds percent (16-2/3%) of the outstanding shares entitled to
vote thereon.  No amendment may change the stated maximum number of authorized
directors to a number greater than two (2) times the stated minimum number of
directors minus one (1).

          No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

     3.3  Election And Term Of Office Of Directors.
          ----------------------------------------

          Directors shall be elected at each annual meeting of shareholders to
hold office until the next annual meeting.  Each director, including a director
elected to fill a vacancy, shall hold office until the expiration of the term
for which elected and until a successor has been elected and qualified.

     3.4  Resignation And Vacancies.
          -------------------------

          Any director may resign effective on giving written notice to the
chairman of the board, the president, the secretary or the Board of Directors,
unless the notice specifies a later time for that resignation to become
effective.  If the resignation of a director is effective at a future time, the
Board of Directors may elect a successor to take office when the resignation
becomes effective.

                                      -8-
<PAGE>

          Vacancies in the Board of Directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote or
written consent of the shareholders or by court order may be filled only by the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present (which shares voting affirmatively
also constitute a majority of the required quorum), or by the unanimous written
consent of all shares entitled to vote thereon.  Each director so elected shall
hold office until the next annual meeting of the shareholders and until a
successor has been elected and qualified.

          A vacancy or vacancies in the Board of Directors shall be deemed to
exist (i) in the event of the death, resignation or removal of any director,
(ii) if the Board of Directors by resolution declares vacant the office of a
director who has been declared of unsound mind by an order of court or convicted
of a felony, (iii) if the authorized number of directors is increased, or (iv)
if the shareholders fail, at any meeting of shareholders at which any director
or directors are elected, to elect the number of directors to be elected at that
meeting.

          The shareholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election
other than to fill a vacancy created by removal, if by written consent, shall
require the consent of the holders of a majority of the outstanding shares
entitled to vote thereon.

     3.5  Place Of Meetings; Meetings By Telephone.
          ----------------------------------------

          Regular meetings of the Board of Directors may be held at any place
within or outside the State of California that has been designated from time to
time by resolution of the board.  In the absence of such a designation, regular
meetings shall be held at the principal executive office of the corporation.
Special meetings of the board may be held at any place within or outside the
State of California that has been designated in the notice of the meeting or, if
not stated in the notice or if there is no notice, at the principal executive
office of the corporation.

          Any meeting, regular or special, may be held by conference telephone
or similar communication equipment, so long as all directors participating in
the meeting can hear one another; and all such directors shall be deemed to be
present in person at the meeting.

     3.6  Regular Meetings.
          ----------------

          Regular meetings of the Board of Directors may be held without notice
if the times of such meetings are fixed by the Board of Directors.

     3.7  Special Meetings; Notice.
          ------------------------

may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two directors.

                                      -9-
<PAGE>

          Notice of the time and place of special meetings shall be delivered
personally or by telephone (including a voice messaging system or other system
or technology designed to record and communicate messages), facsimile,
electronic mail, or other electronic means, to each director or sent by first-
class mail or telegram, charges prepaid, addressed to each director at that
director's address as it is shown on the records of the corporation.  If the
notice is mailed, it shall be deposited in the United States mail at least four
(4) days before the time of the holding of the meeting.  If the notice is
delivered personally or by telephone, telegram, facsimile, electronic mail or
other electronic means, it shall be delivered at least forty-eight (48) hours
before the time of the holding of the meeting.  Any oral notice given personally
or by telephone, facsimile or electronic mail may be communicated either to the
director or to a person at the office of the director who the person giving the
notice has reason to believe will promptly communicate it to the director.  The
notice need not specify the purpose or the place of the meeting, if the meeting
is to be held at the principal executive office of the corporation.

     3.8  Quorum.
          ------

          A majority of the authorized number of directors shall constitute a
quorum for the transaction of business, except to adjourn as provided in Section
3.10 of these bylaws.  Every act or decision done or made by a majority of the
directors present at a duly held meeting at which a quorum is present shall be
regarded as the act of the Board of Directors, subject to the provisions of
Section 310 of the Code (as to approval of contracts or transactions in which a
director has a direct or indirect material financial interest), Section 311 of
the Code (as to appointment of committees), Section 317(e) of the Code (as to
indemnification of directors), the articles of incorporation, and other
applicable law.

          A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

     3.9  Waiver Of Notice.
          ----------------

          Notice of a meeting need not be given to any director (i) who signs a
waiver of notice or a consent to holding the meeting or an approval of the
minutes thereof, whether before or after the meeting, or (ii) who attends the
meeting without protesting, prior thereto or at its commencement, the lack of
notice to such director.  All such waivers, consents, and approvals shall be
filed with the corporate records or made part of the minutes of the meeting.  A
waiver of notice need not specify the purpose of any regular or special meeting
of the Board of Directors.

     3.10 Adjournment.
          -----------

          A majority of the directors present, whether or not constituting a
quorum, may adjourn any meeting to another time and place.

                                      -10-
<PAGE>

     3.11 Notice Of Adjournment.
          ---------------------

          Notice of the time and place of holding an adjourned meeting need not
be given unless the meeting is adjourned for more than twenty-four (24) hours.
If the meeting is adjourned for more than twenty-four (24) hours, then notice of
the time and place of the adjourned meeting shall be given before the adjourned
meeting takes place, in the manner specified in Section 3.7 of these bylaws, to
the directors who were not present at the time of the adjournment.

     3.12 Board Action By Written Consent Without A Meeting.
          -------------------------------------------------

          Any action required or permitted to be taken by the Board of Directors
may be taken without a meeting, provided that all members of the board
individually or collectively consent in writing to that action.  Such action by
written consent shall have the same force and effect as a unanimous vote of the
Board of Directors.  Such written consent and any counterparts thereof shall be
filed with the minutes of the proceedings of the board.

     3.13 Fees And Compensation Of Directors.
          ----------------------------------

          Directors and members of committees may receive such compensation, if
any, for their services and such reimbursement of expenses as may be fixed or
determined by resolution of the Board of Directors.  This Section 3.13 shall not
be construed to preclude any director from serving the corporation in any other
capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

     3.14 Approval Of Loans To Officers.
          -----------------------------

          The corporation may, upon the approval of the Board of Directors
alone, make loans of money or property to, or guarantee the obligations of, any
officer of the corporation or its parent or subsidiary, whether or not a
director, or adopt an employee benefit plan or plans authorizing such loans or
guaranties provided that (i) the Board of Directors determines that such a loan
or guaranty or plan may reasonably be expected to benefit the corporation, (ii)
the corporation has outstanding shares held of record by 100 or more persons
(determined as provided in Section 605 of the Code) on the date of approval by
the Board of Directors, and (iii) the approval of the Board of Directors is by a
vote sufficient without counting the vote of any interested director or
directors.

                                  ARTICLE IV

                                  COMMITTEES
                                  ----------

     4.1  Committees Of Directors.
          -----------------------

          The Board of Directors may, by resolution adopted by a majority of the
authorized number of directors, designate one (1) or more committees, each
consisting of two or more

                                      -11-
<PAGE>

directors, to serve at the pleasure of the board. The board may designate one
(1) or more directors as alternate members of any committee, who may replace any
absent member at any meeting of the committee. The appointment of members or
alternate members of a committee requires the vote of a majority of the
authorized number of directors. Any committee, to the extent provided in the
resolution of the board, shall have all the authority of the board, except with
respect to:

          (a)  the approval of any action which, under the Code, also requires
shareholders' approval or approval of the outstanding shares;

          (b)  the filling of vacancies on the Board of Directors or in any
committee;

          (c)  the fixing of compensation of the directors for serving on the
board or any committee;

          (d)  the amendment or repeal of these bylaws or the adoption of new
bylaws;

          (e)  the amendment or repeal of any resolution of the Board of
Directors which by its express terms is not so amendable or repealable;

          (f)  a distribution to the shareholders of the corporation, except at
a rate or in a periodic amount or within a price range determined by the Board
of Directors; or

          (g)  the appointment of any other committees of the Board of Directors
or the members of such committees.

     4.2  Meetings And Action Of Committees.
          ---------------------------------

          Meetings and actions of committees shall be governed by, and held and
taken in accordance with, the provisions of Article III of these bylaws, Section
3.5 (place of meetings), Section 3.6 (regular meetings), Section 3.7 (special
meetings and notice), Section 3.8 (quorum), Section 3.9 (waiver of notice),
Section 3.10 (adjournment), Section 3.11 (notice of adjournment), and Section
3.12 (action without meeting), with such changes in the context of those bylaws
as are necessary to substitute the committee and its members for the Board of
Directors and its members; provided, however, that the time of regular meetings

the request of the corporation as an employee or agent of another corporation,

          Expenses incurred in defending any civil or criminal action or
proceeding for which indemnification is required pursuant to Section 6.1 or for
which indemnification is permitted pursuant to Section 6.2 following
authorization thereof by the Board of Directors shall be paid by the corporation
in advance of the final disposition of such action or proceeding upon receipt of
an undertaking by or on behalf of the indemnified party to repay such amount if
it shall ultimately be determined that the indemnified party is not entitled to
be indemnified as authorized in this Article VI.

     6.4  Indemnity Not Exclusive.
          -----------------------

directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the articles of
incorporation.

insurance on behalf of any person who is or was a director, officer, employee or

whether or not the corporation would have the power to indemnify him against
such liability under the provisions of this Article VI.

     6.6  Conflicts.
          ---------

          No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

          (1)  That it would be inconsistent with a provision of the articles of
incorporation, these bylaws, a resolution of the shareholders or an agreement in
effect at the time of the accrual of the alleged cause of the action asserted in
the proceeding in which the expenses were incurred or other amounts were paid,
which prohibits or otherwise limits indemnification; or

          (2)  That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

written demand of any shareholder or holder of a voting trust certificate, at
any time during usual business hours, for a purpose reasonably related to the
holder's interests as a shareholder or as the holder of a voting trust

trust certificate, at any reasonable time during usual business hours, for a
purpose reasonably related to the holder's interests as a shareholder or as the

by an agent or attorney and shall include the right to copy and make extracts.
Such rights of inspection shall extend to the records of each subsidiary
corporation of the corporation.

holders of record.

     7.6  Financial Statements.

person making the request, within thirty (30) days thereafter, a copy of a
balance sheet as of the end of such fiscal year and an income statement and

request to the corporation for an income statement of the corporation for the
three-month, six-month or nine-month period of the then current fiscal year
ended more than thirty (30) days before the date of the request, and for a
balance sheet of the corporation as of the end of that period, then the chief
financial officer shall cause such statement or statements to be prepared, if
not already prepared, and shall deliver personally or mail such statement or
statements to the person making the request within thirty (30) days after the
receipt of the request.  If the corporation has not sent to the shareholders its
annual report for the last fiscal year, the statements referred to in the first
paragraph of this Section 7.6 shall likewise be delivered or mailed to the
shareholder or shareholders within thirty (30) days after the request.

          The quarterly income statements and balance sheets referred to in this
section shall be accompanied by the report, if any, of any independent
accountants engaged by the corporation or by the certificate of an authorized
officer of the corporation that the financial statements were prepared without
audit from the books and records of the corporation.

other corporation or corporations standing in the name of this corporation.  The
authority herein granted may be exercised either by such person directly or by
any other person authorized to do so by proxy or power of attorney duly executed
by the person having such authority.


                                 ARTICLE VIII

                                GENERAL MATTERS
                                ---------------

     8.1  Record Date For Purposes Other Than Notice And Voting.
          -----------------------------------------------------

          For purposes of determining the shareholders entitled to receive
payment of any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect of any other lawful
action (other than action by shareholders by written consent without a meeting),
the Board of Directors may fix, in advance, a record date, which shall not be
more than sixty (60) days before any such action.  In that case, only
shareholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding

                                      -19-
<PAGE>

any transfer of any shares on the books of the corporation after the record date
so fixed, except as otherwise provided in the Code.

          If the Board of Directors does not so fix a record date, then the
record date for determining shareholders for any such purpose shall be at the
close of business on the day on which the board adopts the applicable resolution
or the sixtieth (60th) day before the date of that action, whichever is later.

     8.2  Checks; Drafts; Evidences Of Indebtedness.
          -----------------------------------------

          From time to time, the Board of Directors shall determine by
resolution which person or persons may sign or endorse all checks, drafts, other
orders for payment of money, notes or other evidences of indebtedness that are
issued in the name of or payable to the corporation, and only the persons so
authorized shall sign or endorse those instruments.

     8.3  Corporate Contracts And Instruments;  How Executed.
          --------------------------------------------------

          The Board of Directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the Board of Directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

     8.4  Certificates For Shares.
          -----------------------

          A certificate or certificates for shares of the corporation shall be
issued to each shareholder when any of such shares are fully paid.  The Board of
Directors may authorize the issuance of certificates for shares partly paid
provided that these certificates shall state the total amount of the
consideration to be paid for them and the amount actually paid.  All
certificates shall be signed in the name of the corporation by the chairman of
the board or the vice chairman of the board or the president or a vice president
and by the chief financial officer or an assistant treasurer or the secretary or
an assistant secretary, certifying the number of shares and the class or series
of shares owned by the shareholder.  Any or all of the signatures on the
certificate may be facsimile.

          In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed on a certificate ceases to be that
officer, transfer agent or registrar before that certificate is issued, it may
be issued by the corporation with the same effect as if that person were an
officer, transfer agent or registrar at the date of issue.

     8.5  Lost Certificates.
          -----------------

          Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation

                                      -20-
<PAGE>

and canceled at the same time. The Board of Directors may, in case any share
certificate or certificate for any other security is lost, stolen or destroyed,
authorize the issuance of replacement certificates on such terms and conditions
as the board may require; in such case, the board may require indemnification of
the corporation secured by a bond or other adequate security sufficient to
protect the corporation against any claim that may be made against it, including
any expense or liability, on account of the alleged loss, theft or destruction
of the certificate or the issuance of the replacement certificate.

     8.6  Construction; Definitions.
          -------------------------

          Unless the context requires otherwise, the general provisions, rules
of construction, and definitions in the Code shall govern the construction of
these bylaws.  Without limiting the generality of this provision, the singular
number includes the plural, the plural number includes the singular, and the
term "person" includes both a corporation and a natural person.

the corporation, then the authorized number of directors may be changed only by
an amendment of the articles of incorporation.

     9.2  Amendment By Directors.
          ----------------------

          Subject to the rights of the shareholders as provided in Section 9.1

directors pursuant to a bylaw providing for a variable number of directors), may

     2.1  Place of Meetings.
          -----------------

          Meetings of stockholders shall be held at any place, within or outside

office of the Corporation.

     2.2  Annual Meeting.
          --------------

     (a)  The annual meeting of stockholders shall be held each year on a date
and at a time designated by the Board of Directors. At the meeting, directors

     (b)  Nominations of persons for election to the Board of Directors of the
Corporation and the proposal of business to be transacted by the stockholders
may be made at an annual meeting of stockholders (i) pursuant to the
Corporation's notice with respect to such meeting, (ii) by or at the direction

who is entitled to vote at the meeting and who has complied with the notice

     (c)  In addition to the requirements of Section 2.5, for nominations or
other business to be properly brought before an annual meeting by a stockholder
pursuant to clause (iii) of paragraph (b) of this Section 2.2, the stockholder
must have given timely notice thereof in writing to the secretary of the
Corporation and such business must be a proper matter for stockholder action
under the General Corporation Law of Delaware. To be timely, a stockholder's
notice shall be delivered to the secretary at the principal executive offices of
the Corporation not less than 20 days nor more than 90 days prior to the first
anniversary of the preceding year's annual meeting of stockholders; provided,
however, that in the event that the date of the annual meeting is more than 30
days prior to or more than 60 days after such anniversary date, notice by the
stockholder to be timely must be so delivered not earlier than the 90th day
prior to such annual meeting and not later than the close of business on the

proposes to nominate for election or reelection as a director all information
relating to such person that is required to be disclosed in solicitations of
proxies for election of directors, or is otherwise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "Exchange Act") (including such person's written consent to being named in
the proxy statement as a nominee and to serving as a director if elected); (ii)
as to any other business that the stockholder proposes to bring before the
meeting, a brief description of such business, the reasons for conducting such
business at the meeting and any material interest in such business of such
stockholder and the beneficial owner, if any, on whose behalf the proposal is
made; and (iii) as to the stockholder giving the notice and the beneficial
owner, if any, on whose behalf the nomination or proposal is made (A) the name
and address of such stockholder, as they appear on the Corporation's books, and
of such beneficial owner and (B) the class and number of shares of the
Corporation which are owned beneficially and of record by such stockholder and
such beneficial owner.

     (d)  Only such business shall be conducted at an annual meeting of
stockholders as shall have been brought before the meeting in accordance with
the procedures set forth in this Section 2.2. The chairman of the meeting shall
determine whether a nomination or any business proposed to be transacted by the
stockholders has been properly brought before the meeting and, if any proposed
nomination or business has not been properly brought before the meeting, the
chairman shall declare that such proposed business or nomination shall not be
presented for stockholder action at the meeting.

     (e)  For purposes of this Section 2.2, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or a comparable national news service.

     (f)  Nothing in this Section 2.2 shall be deemed to affect any rights of
stockholders to request inclusion of proposals in the Corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

made at a special meeting of stockholders at which directors are to be elected
pursuant to such notice of meeting (i) by or at the direction of the Board of
Directors or (ii) by any stockholder of the Corporation who is a stockholder of
record at the time of giving of notice provided for in Section 2.5, who shall be
entitled to vote at the meeting and who complies with the notice procedures set
forth in Section 2.5.

     2.4  Notice of Stockholder's Meetings; Affidavit of Notice.

          All notices of meetings of stockholders shall be in writing and shall
be sent or otherwise given in accordance with this Section 2.4 of these Bylaws
not less than 10 nor more than 60 days before the date of the meeting to each
stockholder entitled to vote at such meeting (or such longer or shorter time as
is required by Section 2.5 of these Bylaws, if applicable). The notice shall
specify the place, date, and hour of the meeting, and, in the case of a special
meeting, the purpose or purposes for which the meeting is called.

          Written notice of any meeting of stockholders, if mailed, is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the Corporation. An
affidavit of the secretary or an assistant secretary or of the transfer agent of
the Corporation that the notice has been given shall, in the absence of fraud,
be prima facie evidence of the facts stated therein.

     2.5  Advance Notice of Stockholder Nominees.
          --------------------------------------

          Only persons who are nominated in accordance with the procedures set
forth in this Section 2.5 shall be eligible for election as directors.
Nominations of persons for election to the Board of Directors of the Corporation
may be made at a meeting of stockholders by or at the direction of the Board of
Directors or by any stockholder of the Corporation entitled to vote for the
election of directors at the meeting who complies with the notice procedures set
forth in this Section 2.5. Such nominations, other than those made by or at the
direction of the Board of Directors, shall be made pursuant to timely notice in
writing to the secretary of the Corporation. To be timely, a stockholder's
notice shall be delivered to or mailed and received at the principal executive
offices of the Corporation not less than 60 days nor more than 90 days prior to
the meeting; provided, however, that in the event that less than 60 days' notice
or prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholder to be timely must be so received not
later than the close of business on the 10th day following the day on which such
notice of the date of the meeting was mailed or such public disclosure was made.
Such stockholder's notice shall set forth (a) as to each person whom the
stockholder proposes to nominate for election or re-election as a director, (i)
the name, age, business address and residence address of such person, (ii) the
principal occupation or employment of such person, (iii) the class and number of
shares of the Corporation which are beneficially owned by

                                      -7-
<PAGE>

such person and (iv) any other information relating to such person that is
required to be disclosed in solicitations of proxies for election of directors,
or is otherwise required, in each case pursuant to Regulation 14A under the
Exchange Act (including, without limitation, such person's written consent to
being named in the proxy statement as a nominee and to serving as a director if
elected); and (b) as to the stockholder giving the notice (i) the name and
address, as they appear on the Corporation's books, of such stockholder and (ii)
the class and number of shares of the Corporation which are beneficially owned
by such stockholder. At the request of the Board of Directors any person
nominated by the Board of Directors for election as a director shall furnish to
the secretary of the Corporation that information required to be set forth in a
stockholder's notice of nomination which pertains to the nominee. No person
shall be eligible for election as a director of the Corporation unless nominated
in accordance with the procedures set forth in this Section 2.5. The chairman of
the meeting shall, if the facts warrant, determine and declare to the meeting
that a nomination was not made in accordance with the procedures prescribed by
the Bylaws, and if he or she should so determine, he or she shall so declare to
the meeting and the defective nomination shall be disregarded.

     2.6  Quorum.
          ------

     The holders of a majority of the stock issued and outstanding and entitled
to vote thereat, present in person or represented by proxy, shall constitute a
quorum at all meetings of the stockholders for the transaction of business
except as otherwise provided by statute or by the Certificate of Incorporation.
If, however, such quorum is not present or represented at any meeting of the
stockholders, then either (a) the chairman of the meeting or (b) the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented. At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

     2.7  Adjourned Meeting; Notice.
          -------------------------

          When a meeting is adjourned to another time or place, unless these
Bylaws otherwise require, notice need not be given of the adjourned meeting if
the time and place thereof are announced at the meeting at which the adjournment
is taken. At the adjourned meeting the Corporation may transact any business
that might have been transacted at the original meeting. If the adjournment is

shall be determined in accordance with the provisions of Section 2.11 of these
Bylaws, subject to the provisions of Sections 217 and 218 of the General
Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors
and joint owners of stock and to voting trusts and other voting agreements).

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

          Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the Certificate of Incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the Certificate of Incorporation or these Bylaws.

thereof or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board of Directors may fix, in advance, a record date, which shall
not be more than 60 nor less than 10 days before the date of such meeting, nor
more than 60 days prior to any other action. If the Board of Directors does not
so fix a record date:

          (a)  The record date for determining stockholders entitled to notice
of or to vote at a meeting of stockholders shall be at the close of business on
the day next preceding the day on which notice is given, or, if notice is
waived, at the close of business on the day next preceding the day on which the
meeting is held.

          (b)  The record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

          A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

     2.12  Proxies.
           -------

           Each stockholder entitled to vote at a meeting of stockholders may
authorize another person or persons to act for such stockholder by a written
proxy, signed by the stockholder and filed with the secretary of the
Corporation, but no such proxy shall be voted or acted upon after three years
from its date, unless the proxy provides for a longer period. A proxy shall be
deemed signed if the stockholder's name is placed on the proxy (whether by
manual signature, typewriting, telegraphic transmission or otherwise) by the
stockholder or the stockholder's attorney-in-fact. The revocability of a proxy
that states on its face that it is irrevocable shall be governed by the
provisions of Section 212(e) of the General Corporation Law of Delaware.

                                  ARTICLE III

                                   DIRECTORS
                                   ---------

     3.1   Powers.
           ------

           Subject to the provisions of the General Corporation Law of Delaware
and any limitations in the Certificate of Incorporation or these Bylaws relating
to action required to be approved by the stockholders or by the outstanding
shares, the business and affairs of the Corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the Board of
Directors.

     3.2   Number of Directors.
           -------------------

           The number of directors of the corporation shall be seven (7) until
changed by a bylaw amending this Section 3.2, duly adopted by the board of
directors or by the shareholders.

     3.3   Election, Qualification and Term of Office of Directors.
           -------------------------------------------------------

           Except as provided in Section 3.4 of these Bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Directors need not be stockholders unless so required by the
Certificate of Incorporation or these Bylaws, wherein other qualifications for
directors may be prescribed. Each director, including a director elected to fill
a vacancy, shall hold office until his or her successor is elected and qualified
or until his or her earlier resignation or removal.

           Elections of directors need not be by written ballot.

     3.4   Resignation and Vacancies.
           -------------------------

           Any director may resign at any time upon written notice to the
attention of the secretary of the Corporation. When one or more directors so
resigns and the resignation is effective at a future date, a majority of the
directors then in office, including those who have so

                                     -10-
<PAGE>

resigned, shall have power to fill such vacancy or vacancies, the vote thereon
to take effect when such resignation or resignations shall become effective, and
each director so chosen shall hold office as provided in this section in the
filling of other vacancies. A vacancy created by the removal of a director by
the vote of the stockholders or by court order may be filled only by the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present (which shares voting affirmatively
also constitute a majority of the quorum. Each director so elected shall hold
office until the next annual meeting of the stockholders and until a successor
has been elected and qualified.

          Unless otherwise provided in the Certificate of Incorporation or these
Bylaws:

          (a)  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

          (b)  Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
Certificate of Incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

          If at any time, by reason of death or resignation or other cause, the
Corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the Certificate of Incorporation or these Bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

          If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole Board of Directors (as constituted immediately prior to any such
increase), then the Court of Chancery may, upon application of any stockholder
or stockholders holding at least 10% of the total number of the shares at the
time outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

these Bylaws, members of the Board of Directors, or any committee designated by
the Board of Directors, may

                                     -11-
<PAGE>

participate in a meeting of the Board of Directors, or any committee, by means
of conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other, and such
participation in a meeting shall constitute presence in person at the meeting.

     3.6  Regular Meetings.
          ----------------

          Regular meetings of the Board of Directors may be held without notice
at such time and at such place as shall from time to time be determined by the
Board of Directors.

     3.7  Special Meetings; Notice.
          ------------------------

may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two directors.

          Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the Corporation.  If the notice is mailed, it
shall be deposited in the United States mail at least four days before the time
of the holding of the meeting.  If the notice is delivered personally or by
telephone or by telegram, it shall be delivered personally or by telephone or to
the telegraph company at least 48 hours before the time of the holding of the

either to the director or to a person at the office of the director who the
person giving the notice has reason to believe will promptly communicate it to
the director.  The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
Corporation.

     3.8  Quorum.
          ------

          At all meetings of the Board of Directors, a majority of the
authorized number of directors shall constitute a quorum for the transaction of
business and the act of a majority of the directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute or by the Certificate of
Incorporation.  If a quorum is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

          A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

General Corporation Law of Delaware or of the Certificate of Incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.  Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the directors, or members of a committee of directors, need be specified in
any written waiver of notice unless so required by the Certificate of
Incorporation or these Bylaws.

     3.10  Board Action by Written Consent without a Meeting.
           -------------------------------------------------

           Unless otherwise restricted by the Certificate of Incorporation or
these Bylaws, any action required or permitted to be taken at any meeting of the
Board of Directors, or of any committee thereof, may be taken without a meeting
if all members of the Board of Directors or committee, as the case may be,
consent thereto in writing and the writing or writings are filed with the
minutes of proceedings of the Board of Directors or committee.  Written consents
representing actions taken by the board or committee may be executed by telex,
telecopy or other facsimile transmission, and such facsimile shall be valid and
binding to the same extent as if it were an original.

     3.11  Fees and Compensation of Directors.
           ----------------------------------

           Unless otherwise restricted by the Certificate of Incorporation or
these Bylaws, the Board of Directors shall have the authority to fix the

from serving the Corporation in any other capacity and receiving compensation
therefor.

     3.12  Approval of Loans to Officers.
           -----------------------------

           The Corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the Corporation or of its
subsidiary, including any officer or employee who is a director of the
Corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
Corporation.  The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without limitation, a pledge of shares of
stock of the Corporation.  Nothing in this Section 3.2 contained shall be deemed
to deny, limit or restrict the powers of guaranty or warranty of the Corporation
at common law or under any statute.

     3.13  Removal of Directors.
           --------------------

Incorporation or by these Bylaws, any director or the entire Board of Directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that if the stockholders of the Corporation are entitled to cumulative voting,
if less than the entire Board of Directors is to be removed, no director may be
removed without cause if the votes cast against his removal would be sufficient
to elect him if then cumulatively voted at an election of the entire Board of
Directors.

           No reduction of the authorized number of directors shall have the
effect of removing any director prior to the expiration of such director's term
of office.

unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.  Any such

in the Bylaws of the Corporation, shall have and may exercise all the powers and
authority of the Board of Directors in the management of the business and
affairs of the Corporation, and may authorize the seal of the Corporation to be
affixed to all papers that may require it; but no such committee shall have the
power or authority to (a) amend the Certificate of Incorporation (except that a
committee may, to the extent authorized in the resolution or resolutions

permitted by the General Corporation Law of Delaware, indemnify each of its
directors and officers against expenses (including attorneys' fees), judgments,
fines, settlements and other amounts actually and reasonably incurred in
connection with any proceeding, arising by reason of the fact that such person
is or was an agent of the Corporation.  For purposes of this Section 6.1, a
"director" or "officer" of the Corporation includes any person (a) who is or was
a director or officer of the Corporation, (b) who is or was serving at the
request of the Corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (c) who was a director
or officer of a Corporation which was a predecessor corporation of the
Corporation or of another enterprise at the request of such predecessor
corporation.

     6.2   Indemnification of Others.
           -------------------------

           The Corporation shall have the power, to the maximum extent and in
the manner permitted by the General Corporation Law of Delaware, to indemnify
each of its employees and agents (other than directors and officers) against
expenses (including attorneys' fees), judgments, fines, settlements and other
amounts actually and reasonably incurred in connection with any proceeding,
arising by reason of the fact that such person is or was an agent of the
Corporation.

<PAGE>

For purposes of this Section 6.2, an "employee" or "agent" of the Corporation
(other than a director or officer) includes any person (a) who is or was an
employee or agent of the Corporation, (b) who is or was serving at the request
of the Corporation as an employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, or (c) who was an employee or agent of
a corporation which was a predecessor corporation of the Corporation or of
another enterprise at the request of such predecessor corporation.

     6.3  Payment of Expenses in Advance.
          ------------------------------

          Expenses incurred in defending any action or proceeding for which
indemnification is required pursuant to Section 6.1 or for which indemnification
is permitted pursuant to Section 6.2 following authorization thereof by the
Board of Directors shall be paid by the Corporation in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by or on
behalf of the indemnified party to repay such amount if it shall ultimately be
determined that the indemnified party is not entitled to be indemnified as
authorized in this Article VI.

     6.4  Indemnity Not Exclusive.
          -----------------------

          The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any Bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the Certificate of
Incorporation

     6.5  Insurance.
          ---------

          The Corporation may purchase and maintain insurance on behalf of any
person who is or was a director, officer, employee or agent of the Corporation,
or is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,
whether or not the Corporation would have the power to indemnify him or her
against such liability under the provisions of the General Corporation Law of
Delaware.

     6.6  Conflicts.
          ---------

          No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

          (a)  That it would be inconsistent with a provision of the Certificate
of Incorporation, these Bylaws, a resolution of the stockholders or an agreement
in effect at the time of the accrual of the alleged cause of the action asserted
in the proceeding in which the expenses were incurred or other amounts were
paid, which prohibits or otherwise limits indemnification; or

                                     -19-
<PAGE>

           (b) That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.


                                  ARTICLE VII

                              RECORDS AND REPORTS
                              -------------------

     7.1   Maintenance and Inspection of Records.
           -------------------------------------

           The Corporation shall, either at its principal executive offices or
at such place or places as designated by the Board of Directors, keep a record
of its stockholders listing their names and addresses and the number and class
of shares held by each stockholder, a copy of these Bylaws as amended to date,
accounting books, and other records.

           Any stockholder of record, in person or by attorney or other agent,
shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
Corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder.  In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder.  The demand under oath shall be directed to the
Corporation at its registered office in Delaware or at its principal place of
business.

     7.2   Inspection by Directors.
           -----------------------

           Any director shall have the right to examine the Corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his or her position as a director.  The Court of
Chancery is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought.  The Court may summarily order
the Corporation to permit the director to inspect any and all books and records,
the stock ledger, and the stock list and to make copies or extracts therefrom.
The Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

     7.3   Annual Statement to Stockholders.
           --------------------------------

           The Board of Directors shall present at each annual meeting, and at
any special meeting of the stockholders when called for by vote of the
stockholders, a full and clear statement of the business and condition of the
Corporation.

                                GENERAL MATTERS
                                ---------------

     8.1   Checks.
           ------

           From time to time, the Board of Directors shall determine by
resolution which person or persons may sign or endorse all checks, drafts, other
orders for payment of money, notes or other evidences of indebtedness that are
issued in the name of or payable to the Corporation, and only the persons so
authorized shall sign or endorse those instruments.

     8.2   Execution of Corporate Contracts and Instruments.
           ------------------------------------------------

           The Board of Directors, except as otherwise provided in these Bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
Corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the Board of Directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the Corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

     8.3   Stock Certificates; Partly Paid Shares.
           --------------------------------------

           The shares of the Corporation shall be represented by certificates,
provided that the Board of Directors of the Corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the Corporation.  Notwithstanding the adoption of such a resolution by the Board
of Directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the Corporation by the chairman or vice-chairman of
the Board of Directors, or the chief executive officer or the president or vice-
president, and by the chief financial officer or an assistant treasurer, or the
secretary or an assistant secretary of the Corporation representing the number
of shares registered in certificate form.  Any or all of the signatures on the
certificate may be a facsimile.  In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon a
certificate has ceased to be such officer, transfer agent or registrar before
such certificate is issued, it may be issued by the Corporation with the same
effect as if he or she were such officer, transfer agent or registrar at the
date of issue.

           The Corporation may issue the whole or any part of its shares as
partly paid and subject to call for the remainder of the consideration to be
paid therefor.  Upon the face or back of each stock certificate issued to
represent any such partly paid shares, upon the books and records of the
Corporation in the case of uncertificated partly paid shares, the total amount
of the consideration to be paid therefor and the amount paid thereon shall be
stated.  Upon the declaration of any dividend on fully paid shares, the
Corporation shall declare a dividend upon

                                     -21-
<PAGE>

partly paid shares of the same class, but only upon the basis of the percentage
of the consideration actually paid thereon.

     8.4   Special Designation on Certificates.
           -----------------------------------

           If the Corporation is authorized to issue more than one class of
stock or more than one series of any class, then the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights shall be set forth
in full or summarized on the face or back of the certificate that the
Corporation shall issue to represent such class or series of stock; provided,
however, that, except as otherwise provided in Section 202 of the General
Corporation Law of Delaware, in lieu of the foregoing requirements there may be
set forth on the face or back of the certificate that the Corporation shall
issue to represent such class or series of stock a statement that the
Corporation will furnish without charge to each stockholder who so requests the
powers, the designations, the preferences, and the relative, participating,
optional or other special rights of each class of stock or series thereof and
the qualifications, limitations or restrictions of such preferences and/or
rights.

     8.5   Lost Certificates.
           -----------------

           Except as provided in this Section 8.5, no new certificates for
shares shall be issued to replace a previously issued certificate unless the
latter is surrendered to the Corporation and canceled at the same time. The
Corporation may issue a new certificate of stock or uncertificated shares in the
place of any certificate previously issued by it, alleged to have been lost,
stolen or destroyed, and the Corporation may require the owner of the lost,
stolen or destroyed certificate, or the owner's legal representative, to give
the Corporation a bond sufficient to indemnify it against any claim that may be
made against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate or uncertificated shares.

     8.6   Construction; Definitions.
           -------------------------

           Unless the context requires otherwise, the general provisions, rules
of construction, and definitions in the Delaware General Corporation Law shall
govern the construction of these Bylaws.  Without limiting the generality of
this provision, the singular number includes the plural, the plural number
includes the singular, and the term "person" includes both a corporation and a
natural person.

     8.7   Dividends.
           ---------

           The directors of the Corporation, subject to any restrictions
contained in (a) the General Corporation Law of Delaware or (b) the Certificate
of Incorporation, may declare and pay dividends upon the shares of its capital
stock.  Dividends may be paid in cash, in property, or in shares of the
Corporation's capital stock.

                                     -22-
<PAGE>

           The directors of the Corporation may set apart out of any of the
funds of the Corporation available for dividends a reserve or reserves for any
proper purpose and may abolish any such reserve. Such purposes shall include but
not be limited to equalizing dividends, repairing or maintaining any property of
the Corporation, and meeting contingencies.

     8.8   Fiscal Year.
           -----------

           The fiscal year of the Corporation shall be fixed by resolution of
the Board of Directors and may be changed by the Board of Directors.

     8.9   Seal.
           ----

           The Corporation may adopt a corporate seal, which may be altered at
pleasure, and may use the same by causing it or a facsimile thereof, to be
impressed or affixed or in any other manner reproduced.

     8.10  Transfer of Stock.
           -----------------

           Upon surrender to the Corporation or the transfer agent of the
Corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignation or authority to transfer, it shall be the
duty of the Corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate, and record the transaction in its books.

     8.11  Stock Transfer Agreements.
           -------------------------

           The Corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the Corporation to restrict the transfer of shares of stock of the Corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the General Corporation Law of Delaware.

     8.12  Registered Stockholders.
           -----------------------

           The Corporation shall be entitled to recognize the exclusive right of
a person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                   ARTICLE IX

                                   AMENDMENTS
                                   ----------

           The Bylaws of the Corporation may be adopted, amended or repealed by
the stockholders entitled to vote; provided, however, that the Corporation may,
in its Certificate of Incorporation, confer the power to adopt, amend or repeal
Bylaws upon the directors.  The fact

                                     -23-
<PAGE>

that such power has been so conferred upon the directors shall not divest the
stockholders of the power, nor limit their power to adopt, amend or repeal
Bylaws.

                                             ---------------------------
outstanding" shall be determined by the number of shares of Common Stock
- -----------
outstanding which are, and the number of shares of Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities;

               (d)  The term "Holder" means any person owning or having the
                              ------
right to acquire Registrable Securities or any assignee thereof in accordance
with Section 1.12 of this Agreement;

               (e)  The term "Form S-3" means such form under the Securities Act

underwritten public offering by the Company of shares of its Common Stock
pursuant to a registration statement under the Securities Act, in which the Pre-

          1.2  Request for Registration.
               ------------------------

                                      -2-
<PAGE>

               (a)  If the Company shall receive at any time after the earlier
of (i) January 1, 2003, or (ii) six (6) months after the effective date of the
first registration statement for a public offering of securities of the Company
(other than a registration statement relating either to the sale of securities
to employees of the Company pursuant to a stock option, stock purchase or
similar plan or an SEC Rule 145 transaction), a written request from the Holders
of fifty percent (50%) of the Registrable Securities then outstanding that the
Company file a registration statement under the Securities Act covering the
registration of all of their Registrable Securities then outstanding and with
anticipated aggregate proceeds in excess of $15,000,000, then the Company shall,
within ten (10) days of the receipt thereof, give written notice of such request
to all Holders and shall, subject to the limitations of subsection 1.2(b), use
its best efforts to effect as soon as practicable, and in any event within 60
days of the receipt of such request, the registration under the Securities Act
of all Registrable Securities which the Holders request to be registered within
twenty (20) days of the mailing of such notice by the Company in accordance with
Section 3.3.

               (b)  If the Holders initiating the registration request hereunder
("Initiating Holders") intend to distribute the Registrable Securities covered
  ------------------
by their request by means of an underwriting, they shall so advise the Company
as a part of their request made pursuant to this Section 1.2 and the Company
shall include such information in the written notice referred to in subsection
1.2(a). The underwriter will be selected by a majority in interest of the
Initiating Holders and shall be reasonably acceptable to the Company. In such
event, the right of any Holder to include his Registrable Securities in such
registration shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting (unless otherwise mutually agreed by a majority in interest of the
Initiating Holders and such Holder) to the extent provided herein. All Holders
proposing to distribute their securities through such underwriting shall
(together with the Company as provided in subsection 1.5(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting. Notwithstanding any other provision of this
Section 1.2, if the underwriter advises the Initiating Holders in writing that
marketing factors require a limitation of the number of shares to be
underwritten, then the Company shall so advise all Holders of Registrable
Securities which would otherwise be underwritten pursuant hereto, and the number
of shares of Registrable Securities that may be included in the underwriting
shall be allocated among all Holders thereof, including the Initiating Holders,
in proportion (as nearly as practicable) to the amount of Registrable Securities
of the Company owned by each Holder; provided, however, that the number of
                                     --------  -------
shares of Registrable Securities to be included in such underwriting shall not
be reduced unless all other securities are first entirely excluded from the
underwriting.

               (c)  Notwithstanding the foregoing, if the Company shall furnish
to Holders requesting a registration statement pursuant to this Section 1.2, a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company, it would be seriously
detrimental to the Company and its shareholders for such registration statement
to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
for a period of not

                                      -3-
<PAGE>

more than 120 days after receipt of the request of the Initiating Holders;
provided, however, that the Company may not utilize this right more than once in
- --------  -------
any twelve-month period.

               (d)  In addition, the Company shall not be obligated to effect,
or to take any action to effect, any registration pursuant to this Section 1.2:

                    (i)    After the Company has effected two (2) registrations
pursuant to this Section 1.2 and such registrations have been declared or
ordered effective;

                    (ii)   During the period starting with the date sixty (60)
days prior to the Company's good faith estimate of the date of filing of, and
ending on a date one hundred eighty (180) days after the effective date of, a
registration subject to Section 1.3 hereof; provided that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective; or

                    (iii)  If the Initiating Holders propose to dispose of
shares of Registrable Securities that may be immediately registered on Form S-3
pursuant to a request made pursuant to Section 1.4 below.

          1.3  Company Registration. If (but without any obligation to do so)
               --------------------
the Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than the Holders) any of its
stock under the Securities Act in connection with the public offering of such
securities solely for cash (other than a registration relating solely to the
sale of securities to participants in a Company stock plan or a transaction
covered by Rule 145 under the Securities Act, a registration in which the only
stock being registered is Common Stock issuable upon conversion of debt
securities which are also being registered, or any registration on any form
which does not include substantially the same information as would be required
to be included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at such time, promptly give each Holder of at
least 250,000 shares of Registrable Securities, as adjusted for stock splits,
stock dividends and the like (a "Major Investor") written notice of such
                                 --------------
registration. Upon the written request of each Holder given within twenty (20)
days after mailing of such notice by the Company in accordance with Section 3.3,
the Company shall, subject to the provisions of Section 1.8, cause to be
registered under the Securities Act all of the Registrable Securities that each
such Holder has requested to be registered.

          1.4  Form S-3 Registration. In case the Company shall receive from any
               ---------------------
Major Investor a written request or requests that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Major
Investor, the Company will:

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

               (b)  as soon as practicable, effect such registration and all
such qualifications and compliances as may be so requested and as would permit
or facilitate the sale

                                      -4-
<PAGE>

and distribution of all or such portion of such Holder's or Holders' Registrable
Securities as are specified in such request, together with all or such portion
of the Registrable Securities of any other Holder or Holders joining in such
request as are specified in a written request given within 15 days after receipt
of such written notice from the Company; provided, however, that the Company
                                         --------  -------
shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 1.4: (i) if Form S-3 is not available for
such offering by the Holders; (ii) if the Holders, together with the holders of
any other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public (net of any underwriters' discounts or
commissions) of less than $1,000,000; (iii) if the Company shall furnish to the
Holders a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such Form S-3
Registration to be effected at such time, in which event the Company shall have
the right to defer the filing of the Form S-3 registration statement for a
period of not more than 120 days after receipt of the request of the Holder or
Holders under this Section 1.4; provided, however, that the Company shall not
                                --------  -------
utilize this right more than once in any twelve month period; (iv) if the
Company has, within the twelve (12) month period preceding the date of such
request, already effected two registrations on Form S-3 for the Holders pursuant
to this Section 1.4; (v) in any particular jurisdiction in which the Company
would be required to qualify to do business or to execute a general consent to
service of process in effecting such registration, qualification or compliance;
or (vi) during the period ending one hundred eighty (180) days after the
effective date of a registration statement subject to Section 1.3.

               (c)  Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. Registrations effected pursuant to this
Section 1.4 shall not be counted as demands for registration or registrations
effected pursuant to Sections 1.2 or 1.3, respectively.

          1.5  Obligations of the Company. Whenever required under this Section
               --------------------------
1 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

               (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to one hundred twenty (120) days. The
Company shall not be required to file, cause to become effective or maintain the
effectiveness of any registration statement that contemplates a distribution of
securities on a delayed or continuous basis pursuant to Rule 415 under the
Securities Act.

               (b)  Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to

                                      -5-
<PAGE>

the disposition of all securities covered by such registration statement for up
to one hundred twenty (120) days.

               (c)  Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

               (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
- --------
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

               (e)  In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

               (f)  Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing, such obligation to continue for one hundred twenty (120) days.

               (g)  Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

               (h)  Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

               (i)  Use its best efforts to furnish, at the request of any
Holder requesting registration of Registrable Securities pursuant to this
Section 1, on the date that such Registrable Securities are delivered to the
underwriters for sale in connection with a registration pursuant to this Section
1, if such securities are being sold through underwriters, or, if such
securities are not being sold through underwriters, on the date that the
registration statement with respect to such securities becomes effective, (i) an
opinion, dated such date, of the counsel representing the Company for the
purposes of such registration, in form and substance as is customarily given to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities and
(ii) a letter dated such date, from the independent certified public accountants
of the Company, in form and substance as is customarily given by independent
certified public accountants to underwriters

                                      -6-
<PAGE>

in an underwritten public offering, addressed to the underwriters, if any, and
to the Holders requesting registration of Registrable Securities.

          1.6  Furnish Information. It shall be a condition precedent to the
               -------------------
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities. The Company shall have no obligation with respect to any
registration requested pursuant to Section 1.2 or Section 1.4 of this Agreement
if, as a result of the application of the preceding sentence, the number of
shares or the anticipated aggregate offering price of the Registrable Securities
to be included in the registration does not equal or exceed the number of shares
or the anticipated aggregate offering price required to originally trigger the
Company's obligation to initiate such registration as specified in subsection
1.2(a) or subsection 1.4(b)(2), whichever is applicable.

          1.7  Expenses of Registration.
               ------------------------

               (a)  Demand Registration. All expenses other than underwriting
                    -------------------
discounts and commissions incurred in connection with registrations, filings or
qualifications pursuant to Section 1.2, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel for the selling Holders selected by the Holders of
a majority of the Registrable Securities to be registered with the approval of
the Company, which approval shall not be unreasonably withheld, shall be borne
by the Company; provided, however, that the Company shall not be required to pay
                --------  -------
for any expenses of any registration proceeding begun pursuant to Section 1.2 if
the registration request is subsequently withdrawn at the request of the Holders
of a majority of the Registrable Securities to be registered (in which case all
participating Holders shall bear such expenses), unless the Holders of a
majority of the Registrable Securities agree to forfeit their right to one
demand registration pursuant to Section 1.2.

               (b)  Company Registration. All expenses other than underwriting
                    --------------------
discounts and commissions incurred in connection with registrations, filings or
qualifications of Registrable Securities pursuant to Section 1.3 for each Holder
(which right may be assigned as provided in Section 1.12), including (without
limitation) all registration, filing, and qualification fees, printers' and
accounting fees, fees and disbursements of counsel for the Company and the
reasonable fees and disbursements of one counsel for the selling Holder or
Holders selected by the Holders of a majority of the Registrable Securities to
be registered with the approval of the Company, which approval shall not be
unreasonably withheld, shall be borne by the Company.

               (c)  Registration on Form S-3. All expenses incurred in
connection with a registration requested pursuant to Section 1.4, including
(without limitation) all registration, filing, qualification, printers' and
accounting fees and the reasonable fees and disbursements of one counsel for the
selling Holder or Holders selected by the Holders of a

                                      -7-
<PAGE>

majority of the Registrable Securities to be registered with the approval of the
Company, which approval shall not be unreasonably withheld, and counsel for the
Company, and any underwriters' discounts or commissions associated with
Registrable Securities, shall be borne pro rata by the Holder or Holders
participating in the Form S-3 Registration.

               1.8  Underwriting Requirements. In connection with any offering
                    -------------------------
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters determine in their sole
discretion will not jeopardize the success of the offering (the securities so
included to be apportioned pro rata among the selling shareholders according to
the total amount of securities entitled to be included therein owned by each
selling shareholder or in such other proportions as shall mutually be agreed to
by such selling shareholders) but in no event shall (i) the amount of securities
of the selling Holders included in the offering be reduced below thirty percent
(30 %) of the total amount of securities included in such offering, unless such
offering is the initial public offering of the Company's securities, in which
case, the selling shareholders may be excluded entirely if the underwriters make
the determination described above and no other shareholder's securities are
included, or (ii) any of the Costella Kirsch Shares be included if any
Registrable Securities other than the Costella Kirsch Shares are excluded, or
(iii) any shares of Common Holders' Stock be included if any Registrable
Securities other than the shares of Common Holders' Stock and Costella Kirsch
Shares are excluded. For purposes of the preceding parenthetical concerning
apportionment, for any selling shareholder that is a Holder of Registrable
Securities and that is a partnership or corporation, the partners, retired
partners and shareholders of such Holder, or the estates and family members of
any such partners and retired partners and any trusts for the benefit of any of
the foregoing persons shall be deemed to be a single "selling shareholder," and
                                                      -------------------
any pro-rata reduction with respect to such "selling shareholder" shall be based
upon the aggregate amount of shares carrying registration rights owned by all
entities and individuals included in such "selling shareholder," as defined in
this sentence.

          1.9  Delay of Registration. No Holder shall have any right to obtain
               ---------------------
or seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

          1.10 Indemnification.  In the event any Registrable Securities are
               ---------------
included in a registration statement under this Section 1:

                                      -8-
<PAGE>

               (a)  To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Securities
Act) for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), against any losses, claims,
                              ------------
damages, or liabilities (joint or several) to which they may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement
                                         ---------
or alleged untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading, or (iii) any violation
or alleged violation by the Company of the Securities Act, the Exchange Act, any
state securities law or any rule or regulation promulgated under the Securities
Act, the Exchange Act or any state securities law; and the Company will pay to
each such Holder, underwriter or controlling person, as incurred, any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
                                                              --------  -------
that the indemnity agreement contained in this subsection 1.10(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld), nor shall the Company be
liable to any Holder, underwriter or controlling person for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by any such Holder, underwriter or controlling person.

               (b)  To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter,
any other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such
Holder will pay, as incurred, any legal or other expenses reasonably incurred by
any person intended to be indemnified pursuant to this subsection 1.10(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
                      --------  -------
in this subsection 1.10(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; provided, that in no event shall any indemnity under this subsection
          --------
1.10(b) exceed the net proceeds from the offering received by such Holder,
except in the case of willful fraud by such Holder.

                                      -9-
<PAGE>

               (c)  Promptly after receipt by an indemnified party under this
Section 1.10 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.10, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
                             --------  -------
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the reasonable fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.10, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.10.

               (d)  If the indemnification provided for in this Section 1.10 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage or expense as well as any other relevant equitable
considerations; provided, that in no event shall any contribution by a Holder

under this Subsection 1.10(d) exceed the net proceeds from the offering received
by such Holder, except in the case of willful fraud by such Holder. The relative
fault of the indemnifying party and of the indemnified party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission to state a material fact relates to
information supplied by the indemnifying party or by the indemnified party and
the parties' relative intent, knowledge, access to information, and opportunity
to correct or prevent such statement or omission.

               (e)  Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

               (f)  The obligations of the Company and Holders under this
Section 1.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

               ---------------------------------------------
making available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

               (a)  make and keep public information available, as those terms
are understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public so long as the
Company remains subject to the periodic reporting requirements under Sections 13
or 15(d) of the Exchange Act;

               (b)  take such action, including the voluntary registration of
its Common Stock under Section 12 of the Exchange Act, as is necessary to enable
the Holders to utilize Form S-3 for the sale of their Registrable Securities,
such action to be taken as soon as practicable after the end of the fiscal year
in which the first registration statement filed by the Company for the offering
of its securities to the general public is declared effective;

               (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

               (d)  furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144 (at
any time after ninety (90) days after the effective date of the first
registration statement filed by the Company), the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements), or that it qualifies as a registrant whose securities may be
resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of
the most recent annual or quarterly report of the Company and such other reports
and documents so filed by the Company, and (iii) such other information as may
be reasonably requested in availing any Holder of any rule or regulation of the
SEC which permits the selling of any such securities without registration or
pursuant to such form.

          1.12 Assignment of Registration Rights.  The rights to cause the
               ---------------------------------
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to (i) a transferee
or assignee of all of such Holder's Registrable Securities, (ii) another Holder
of Registrable Securities who prior to such assignment or transfer held
Registrable Securities, (iii) a transferee or assignee of at least ten percent
(10%) of the Company's securities outstanding at the time of such transfer or
assignment, or (iv) an affiliated limited partnership, limited partner, general
partner or other affiliate of a Major Investor, provided the Company is, within
                                                --------
a reasonable time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned; and provided, further, that
                                                       --------  -------
such assignment shall be effective only if immediately following such transfer
the further disposition of such securities by the transferee or assignee is
restricted under the Securities Act, and provided, further, that in any such
                                         --------  -------
transfer or assignment such transferee or assignee shall not be a person

                                      -11-
<PAGE>

or entity reasonably deemed by the Company to be a competitor of the Company.
For the purposes of determining the number of shares of Registrable Securities
held by a transferee or assignee, the holdings of transferees and assignees of a
partnership who are partners or retired partners of such partnership (including
spouses and ancestors, lineal descendants and siblings of such partners or
spouses who acquire Registrable Securities by gift, will or intestate
succession) shall be aggregated together and with the partnership; provided that
all assignees and transferees who would not qualify individually for assignment
of registration rights shall have a single attorney-in-fact for the purpose of
exercising any rights, receiving notices or taking any action under Section 1.

          1.13 Limitations on Subsequent Registration Rights. From and after the
               ---------------------------------------------
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of a majority of the outstanding Registrable Securities, enter
into any agreement with any holder or prospective holder of any securities of
the Company which would allow such holder or prospective holder (a) to include
such securities in any registration filed under Section 1.2 hereof, unless under
the terms of such agreement, such holder or prospective holder may include such
securities in any such registration only to the extent that the inclusion of his
securities will not reduce the amount of the Registrable Securities of the
Holders which is included or (b) to make a demand registration which could
result in such registration statement being declared effective prior to the
earlier of either of the dates set forth in subsection 1.2(a) or within one
hundred twenty (120) days of the effective date of any registration effected
pursuant to Section 1.2.

          1.14 Market-Standoff Agreement.
               -------------------------

               (a)  Market-Standoff Period; Agreement.  In connection with a
                    ---------------------------------
public offering of the Company's securities and upon request of the Company or
the underwriters managing such offering of the Company's securities, each Holder
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 such public offering.

               (b)  Limitations. The obligations described in Section 1.14(a)
                    -----------
shall apply only if all officers and directors of the Company enter into similar
agreements, and shall not apply to a registration relating solely to employee
benefit plans, or to a registration relating solely to a transaction pursuant to
Rule 145 under the Securities Act.

               (c)  Stop-Transfer Instructions.  In order to enforce the
                    --------------------------
foregoing covenants, the Company may impose stop-transfer instructions with
respect to the securities of each Holder (and the securities of every other
person subject to the restrictions in Section 1.14(a)).

               (d)  Transferees Bound. Each Holder agrees that it will not
                    -----------------
transfer securities of the Company unless each transferee agrees in writing to
be bound by all of the

                                      -12-
<PAGE>

provisions of this Section 1.14, provided that this Section 1.14(d) shall not
                                 --------
apply to transfers pursuant to a registration statement.

          1.15 Termination of Registration Rights. No Holder shall be entitled
               ----------------------------------
to exercise any right provided for in this Section 1 after the earlier of (i)
five (5) years following the consummation of a Qualified IPO, or (ii) such time
as Rule 144 or another similar exemption under the Securities Act is available
for the sale of all of such Holder's shares during a three (3)-month period
without registration.

     2.   Covenants of the Company.
          ------------------------

          2.1  Delivery of Financial Statements. The Company shall deliver to
               --------------------------------
each Major Investor (other than a Major Investor reasonably deemed by the
Company to be a competitor of the Company):

               (a)  as soon as practicable, but in any event within ninety (90)
days after the end of each fiscal year of the Company, an income statement for
such fiscal year, a balance sheet of the Company and statement of shareholder's
equity as of the end of such year, and a statement of cash flows for such year,
such year-end financial reports to be in reasonable detail, prepared in
accordance with generally accepted accounting principles ("GAAP"), and audited
                                                           ----
and certified by an independent public accounting firm of nationally recognized
standing selected by the Company;

               (b)  as soon as practicable, but in any event within thirty (30)
days after the end of each of the first three (3) quarters of each fiscal year
of the Company, an unaudited profit or loss statement, a statement of cash flows
for such fiscal quarter and an unaudited balance sheet as of the end of such
fiscal quarter; and

               (c)  as soon as practicable, but in any event thirty (30) days
prior to the end of each fiscal year, a budget for the next fiscal year,
prepared on a monthly basis.

          2.2  Inspection. The Company shall permit each Major Investor (except
               ----------
for a Major Investor reasonably deemed by the Company to be a competitor of the
Company), at such Holder's expense, to visit and inspect the Company's
properties, to examine its books of account and records and to discuss the
Company's affairs, finances and accounts with its officers, all at such
reasonable times as may be requested by the Investor; provided, however, that
                                                      --------  -------
the Company shall not be obligated pursuant to this Section 2.2 to provide
access to any information which it reasonably considers to be a trade secret or
similar confidential information.

          2.3  Right of First Offer. Subject to the terms and conditions
               --------------------
specified in this Section 2.3, the Company hereby grants to each Major Investor
a right of first offer with respect to future sales by the Company of its Shares
(as hereinafter defined). For purposes of this Section 2.3, a Major Investor
includes any general partners and affiliates of a Major Investor. A Major
Investor who chooses to exercise the right of first offer may designate as
purchasers under such right itself or its partners or affiliates (other than a
person or entity reasonably deemed by the Company to be a competitor of the
Company) in such proportions as it deems appropriate.

                                      -13-
<PAGE>

          Each time the Company proposes to offer any shares of, or securities
convertible into or exercisable for any shares of, any class of its capital
stock ("Shares"), the Company shall first make an offering of such Shares to
        ------
each Major Investor in accordance with the following provisions:

               (a)  The Company shall deliver a notice by certified mail
("Notice") to the Major Investors stating (i) its bona fide intention to offer
  ------
such Shares, (ii) the number of such Shares to be offered, and (iii) the price
and terms, if any, upon which it proposes to offer such Shares.

               (b)  Within 15 calendar days after delivery of the Notice, the
Major Investors may elect to purchase or obtain, at the price and on the terms
specified in the Notice, up to that portion of such Shares which equals the
proportion that the number of shares of Common Stock issued or issuable upon
conversion and exercise of all convertible or exercisable securities then held,
by such Major Investor bears to the total number of shares of Common Stock then
issued or issuable upon conversion and exercise of all convertible or
exercisable securities.

               (c)  The Company may, during the 45-day period following the
expiration of the period provided in subsection 2.3(b) hereof, offer the
remaining unsubscribed portion of the Shares to any person or persons at a price
not less than, and upon terms no more favorable to the offeree than those
specified in the Notice. If the Company does not enter into an agreement for the
sale of the Shares within such period, or if such agreement is not consummated
within 60 days of the execution thereof, the right provided hereunder shall be
deemed to be revived and such Shares shall not be offered unless first reoffered
to the Holders in accordance herewith.

               (d)  The right of first offer in this paragraph 2.3 shall not be
applicable (i) to the issuance or sale of shares of Common Stock (or options
therefor) to employees, consultants and directors, pursuant to plans or
agreements approved by the Board of Directors, (ii) to or after consummation of
a Qualified IPO, (iii) to the issuance of securities pursuant to the conversion
or exercise of convertible or exercisable securities, (iv) to the issuance of
securities in connection with a bona fide acquisition of or by the Company,
whether by merger, consolidation, sale of assets, sale or exchange of stock or
otherwise, (v) to the issuance of securities to financial institutions or other
lenders or lessors in connection with loans, leases, equipment financings, or
similar transactions, (vi) to the issuance or sale of the Series B Shares, (vii)
to the issuance of securities in connection with research and development
partnerships, licensing or collaborative arrangements and similar transactions
approved by the Board of Directors, or (viii) to the issuance of securities
that, with unanimous approval of the Board of Directors of the Company, are not
offered to any existing shareholder of the Company.

          2.4  Termination of Covenants.
               ------------------------

               (a)  The covenants set forth in this Section 2 shall terminate as
to each Holder and be of no further force or effect upon the earlier of the
following dates: (i) immediately prior to the consummation of a Qualified IPO,
(ii) when the Company shall sell, convey, or otherwise dispose of all or
substantially all of its property or business or merge into or

                                      -14-
<PAGE>

consolidate with any other corporation (other than a wholly-owned subsidiary
corporation) or effect any other transaction or series of related transactions
in which the shareholders of the Company immediately prior thereto own less than
a majority of the outstanding shares of voting stock of the Company (or its
successor or parent) immediately thereafter, provided that this subsection (ii)
shall not apply to a merger effected exclusively for the purpose of changing the
domicile of the Corporation, or (iii) when the Company first becomes subject to
the periodic reporting requirements of Sections 13 or 15(d) of the Exchange Act.

     3.   Miscellaneous.
          -------------

          3.1  Successors and Assigns. Except as otherwise provided in this
               ----------------------
Agreement, the terms and conditions of this Agreement shall inure to the benefit
of and be binding upon the respective permitted successors and assigns of the
parties (including transferees of any of the Series A Shares, Series B Shares or
any Common Stock issued upon conversion thereof). Nothing in this Agreement,
express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as
expressly provided in this Agreement.

          3.2  Amendments and Waivers.  Any term of this Agreement may be
               ----------------------
amended or waived only with the written consent of the Company and the holders
of a majority of the Registrable Securities then outstanding, not including the
Common Holders' Stock; provided that if such amendment would reasonably affect
the Common Holders' Stock (i) in a manner different than the Registrable
Securities other than the shares of Common Holders' Stock and (ii) in a manner
adverse to the interests of the holders of the Common Holders' Stock, then such
amendment shall require the consent of the holder or holders of a majority of
the Common Holders' Stock. Any amendment or waiver effected in accordance with
this paragraph shall be binding upon each holder of any Registrable Securities
then outstanding, each future holder of all such Registrable Securities, and the
Company.

          3.3  Notices. Unless otherwise provided, any notice required or
               -------
permitted by this Agreement shall be in writing and shall be deemed sufficient
upon delivery, when delivered personally or by overnight courier or by facsimile
transmission (as evidenced by sender's confirmation receipt), or forty-eight
(48) hours after being deposited in the U.S. mail, as certified or registered
mail, with postage prepaid, and addressed to the party to be notified at such
party's address or fax number as set forth below or on exhibits attached hereto
                                                       --------
or as subsequently modified by written notice.

          3.4  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 (a) such
provision shall be excluded from this Agreement, (b) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (c) the
balance of the Agreement shall be enforceable in accordance with its terms.

                                      -15-

          3.5  Governing Law. This Agreement and all acts and transactions
               -------------
pursuant hereto shall be governed, construed and interpreted in accordance with
the laws of the State of California, without giving effect to principles of
conflicts of laws.

          3.6  Counterparts. This Agreement may be executed in two or more
               ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

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

               --------------------
acquired by affiliated entities or persons shall be aggregated together for the
purpose of determining the availability of any rights under this Agreement.

               ---------------------------------------------------------------
Prior Rights Agreement. Pursuant to Section 3.2 of the Prior Rights Agreement,
- ----------------------
the Company and the undersigned holders of the requisite majority of Registrable
Securities needed to amend the Prior Rights Agreement, do hereby (i) waive the
Right of First Offer (including any notice provision) contained in Section 2.3
of the Prior Rights Agreement with respect to the issuance of the Series B
Shares and (ii) hereby amend and restate the Prior Rights Agreement to read in
its entirety as set forth in this Agreement.

make grants to Reporting Persons under the Plan, which Committee shall be

Rule 16b-3. Once appointed, such Committee shall continue to serve in its
designated capacity until otherwise directed by the Board. From time to time the
Board may increase the size of the Committee and appoint additional members
thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies, however caused, and remove all members of
the Committee and thereafter directly make grants to Reporting Persons under the
Plan, all to the extent permitted by Rule 16b-3.

               (iii)  Administration With Respect to Consultants and Other
                      ----------------------------------------------------
Employees.  With respect to grants of Options or Stock Purchase Rights to
- ---------
Employees or Consultants who are not Reporting Persons, the Plan shall be
administered by (A) the Board or (B) a Committee designated by the Board, which

Laws. Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused, and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws.

          (c)  Powers of the Administrator.  Subject to the provisions of the
               ---------------------------
Plan and in the case of a Committee, the specific duties delegated by the Board
to such Committee, and subject to the approval of any relevant authorities,
including the approval, if required, of any Stock Exchange, 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(o) of the Plan;

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

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

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

               (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;

                                      -5-
<PAGE>

               (vii)  to determine whether and under what circumstances an
Option may be settled in cash under Section 9(g) 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;

               (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.   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:

                      (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.

                      (B)  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.

               (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

                                      -7-
<PAGE>

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.

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

          (a)  Procedure for Exercise; Rights as a Shareholder.  Any Option
               -----------------------------------------------
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator 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 Listed Security shall
become exercisable at the rate of at least 20% per year over five years from the
date the Option is granted.  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. 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

                                      -8-
<PAGE>

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 8(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 12 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 9(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 and not
exceeding three months) 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 9(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.
               ----------------------

               (i)    Notwithstanding Section 9(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

                                      -9-
<PAGE>

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

          (g)  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.

                                      -10-
<PAGE>

     10.  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 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.

          (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 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 12
of the Plan.

     11.  Stock Withholding to Satisfy Withholding Tax Obligations.  At the
          --------------------------------------------------------
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph. When an Optionee incurs tax liability in
connection with an Option or Stock Purchase Right, which tax liability is
subject to tax withholding under applicable tax laws, and the Optionee is
obligated to pay the Company an amount required to be withheld under applicable
tax laws, the Optionee may satisfy the withholding tax obligation by one or some

                                      -11-
<PAGE>

combination of the following methods: (a) by cash or check payment, (b) out of
the Optionee's current compensation, (c) if permitted by the Administrator, in
its discretion, by surrendering to the Company Shares that (i) in the case of
Shares previously acquired from the Company, have been owned by the Optionee for
more than six months on the date of surrender, and (ii) have a Fair Market Value
on the date of surrender equal to or less than the amount required to be
withheld, or (d) by electing to have the Company withhold from the Shares to be
issued upon exercise of the Option, or the Shares to be issued in connection
with the Stock Purchase Right, if any, that number of Shares having a Fair
Market Value equal to the amount required to be withheld. For this purpose, the
Fair Market Value of the Shares to be withheld shall be determined on the date
that the amount of tax to be withheld is to be determined (the "Tax Date").
                                                                --------

     Any surrender by a Reporting Person of previously owned Shares to satisfy
tax withholding obligations arising upon exercise of this Option must comply
with the applicable provisions of Rule 16b-3.

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

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

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

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

     12.  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, 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

                                      -12-
<PAGE>

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)  Change in Control.  In the event of a Change in Control, each
               -----------------
outstanding Option or 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, unless such successor corporation does
not agree to assume the outstanding Options or Stock Purchase Rights or to
substitute equivalent options or rights, in which case the vesting of such
Option or stock obtainable upon exercise of any Stock Purchase Right outstanding
or previously granted under the Plan, shall automatically be accelerated in full
such that the Option shall be exercisable as to 100% of the Shares or the
Company's Repurchase Option shall terminate as to 100% of the Shares, as
applicable, upon the consummation of the Change of Control transaction.

          For purposes of this Section 12(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 12); 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

                                      -13-
<PAGE>

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.

     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 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, after the date, if any,
upon which the Common Stock becomes a Listed Security, the Administrator may in
its discretion 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 the Option or Stock Purchase Right, only by
such holder or a transferee permitted by this Section 13.

     14.  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.

     15.  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.

     16.  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

                                      -14-
<PAGE>

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.

     17.  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.

     18.  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.

     19.  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.

     20.  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 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
<PAGE>

Expiration Date set forth in the Notice of Stock Option Grant), exercise this
Option to the extent 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. 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. However, the timing of this income recognition
may be deferred for up to 6 months if Optionee is subject to Section 16 of the
Exchange Act. 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
<PAGE>

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: (a) by cash payment, (b) out of Optionee's current compensation, (c) if
permitted by the Administrator, in its discretion, by surrendering to the
Company Shares which (i) 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 (ii) have a Fair Market Value on the date of surrender equal to
or greater than Optionee's marginal tax rate times the ordinary income
recognized, or (d) by electing to have the Company withhold from the Shares to
be issued upon exercise of the Option that number of Shares having a Fair Market
Value equal to the amount required to be withheld. For this purpose, the Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined (the "Tax Date").
                                                           --------

     If Optionee is subject to Section 16 of the Exchange Act (an "Insider"),
                                                                   -------
any surrender of previously owned Shares to satisfy tax withholding obligations
arising upon exercise of this Option must comply with the applicable provisions
of Rule 16b-3 promulgated under the Exchange Act ("Rule 16b-3").
                                                   ----------

     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:

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

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

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

     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.

                    (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
<PAGE>

intention to sell or otherwise transfer such Shares; (ii) the name of each
proposed purchaser 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.
<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
<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
<PAGE>

                      WITH, THE SALE OR DISTRIBUTION THEREOF. 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
               -------------

modification of or 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. The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party.

          (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

                        COMMON STOCK PURCHASE AGREEMENT
                        -------------------------------

     This Common Stock Purchase Agreement (the "Agreement") is made as of August
                                                ---------
30, 1996 by and between Dr. Dean Online, Inc., a California corporation (the
"Company"), and ________________("Purchaser").
 -------                          ---------

     1.  Sale of Stock.  Subject to the terms and conditions hereof, on the
         -------------
Closing Date (as defined below) the Company will issue and sell to Purchaser,
and Purchaser agrees to purchase from the Company, ____________shares of the
Company's Common Stock (the "Shares") at a purchase price of ___________ per
                             ------

         -------
(the "Closing") shall be held at the principal office of the Company
      -------
simultaneously with the execution of this Agreement by the parties or at such
other time and place as the Company and Purchaser shall agree (the "Closing
                                                                    -------

certain Distribution Agreement, dated October 1, 1995, between NTN and
Purchaser.

     3.  Limitations on Transfer.  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.  If, at any time after the date of this
              ----------------------
Agreement, Purchaser or Purchaser's transferee desires to sell or transfer
Shares, Purchaser shall first offer such Shares for sale to the Company by means
of a written notice (the "Transfer Notice") stating the name, address and phone
                          ---------------
number of each proposed transferee and the terms and conditions upon which
Purchaser proposes to dispose of such Shares.  For a period of thirty (30) days
following receipt by the Company of the Transfer Notice, the Company shall have
a right to purchase such Shares upon the same terms as (or terms as similar as
reasonably possible to) the terms contained in the Transfer Notice (the "Right
                                                                         -----
of First Refusal").  If the Company desires to exercise the Right of First
- ----------------
Refusal, it shall so notify Purchaser in writing within such thirty day period.
In the event the Shares are not disposed of on the terms proposed in the
Transfer Notice within thirty (30) days following the lapse of the Right of
First Refusal, or if at any time Purchaser proposes to change the price or other
terms to make them more favorable to the buyer, then the Shares shall once again
be subject to the Right of First Refusal.

         (b)  Involuntary Transfer.  In the event, at any time after the date of
              --------------------
this Agreement, of any transfer by operation of law or other involuntary

record holder thereof, (i) the person acquiring the
<PAGE>

Shares shall promptly notify the Secretary of the Company of such transfer and
(ii) the Company shall have an option, for a period of thirty (30) days
following receipt of such notice, to purchase all of the Shares so transferred.
The price per Share shall be set by the Board of Directors of the Company to
reflect the current value of the Shares in terms of present earnings and future
prospects of the Company. The decision of the Board of Directors as to the
purchase price shall be final.

          (c)  Assignment.  The Company's right to purchase any 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 requirements of this Agreement are met.

          (e)  Termination of Right of First Refusal. The Right of First Refusal
               -------------------------------------
shall terminate at such time as a Public Market exists for the Company's capital
stock (or any other stock issued in exchange for the Shares purchased under this
Agreement).  For the purpose of this Agreement, a "Public Market" shall be
                                                   -------------
deemed to exist if (i) such stock is listed on a national securities exchange
(as that term is used in the Securities Exchange Act of 1934, as amended) or
(ii) such stock is traded on the over-the-counter market and prices are
published daily on business days in a recognized financial journal.  Upon
termination of the Right of First Refusal, a new certificate or certificates
representing the Shares not repurchased shall be issued, on request, without the
legend referred to in Section 5(b) below and delivered to Purchaser.

          (f)  Lockup.  Notwithstanding the foregoing, Purchaser and Purchaser's
               ------
transferees will not, without the prior written consent of the Company, offer,
sell, contract to sell or grant any option to purchase or otherwise dispose of
any of the Shares for a period of 180 days following the effectiveness of a
registration statement under the Securities Act of 1933, as amended, in
connection with the Company's initial public offering of securities.

          (g)  Exempt Transfers.  The restrictions on transfer of this Section 3
               ----------------
shall not apply to a transfer of Shares to Purchaser's ancestors or descendants
or spouse or to a trustee for their benefit, provided that such transferees
shall agree in writing to take such Shares subject to all the terms of this
Agreement, including restrictions on further transfer.

     4.   Investment 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 Purchaser's own account only and not
with a view to, or for resale in connection with,

                                      -2-
<PAGE>

any "distribution" thereof within the meaning of the Securities Act of 1933, as
amended (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 further acknowledges and understands that the Shares
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. Purchaser
further acknowledges and understands that the Company is under no obligation to
register the Shares. Purchaser understands that the certificate evidencing the
Shares will be imprinted with a legend which prohibits the transfer of the
Shares unless they are registered or such registration is not required in the
opinion of counsel for the Company.

          (d)  Purchaser is aware of the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof (or from an affiliate of such issuer), in a non-public
offering subject to the satisfaction of certain of the conditions specified by
Rule 144, including, among other things: (1) the sale being made through a
broker in an unsolicited "brokers transaction" or in transactions directly with
a market maker (as said term is defined under the Securities Exchange Act of
1934); and, in the case of an affiliate, (2) the availability of certain public
information about the Company, and the amount of securities being sold during
any three month period not exceeding the limitations specified in Rule 144(e),
if applicable.

     In the event that the Company does not qualify under Rule 701, then the
Shares may be resold in certain limited circumstances subject to the provisions
of Rule 144, which requires among other things: (1) the resale occurring not
less than two years after the party has purchased, and made full payment for,
within the meaning of Rule 144, the Shares to be sold; and, in the case of an
affiliate, or of a non-affiliate who has held the Shares less than three years,
(2) the availability of certain public information about the Company, (3) the
sale being made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as such term is defined under the
Securities Exchange Act of 1934), and (4) the amount of securities being sold
during any three month period not exceeding the specified limitations stated
therein, if applicable. Purchaser further acknowledges that payment for the
Shares with a promissory note is not deemed payment unless the note is secured
by assets other than the Shares.

          (e)  Purchaser further understands that at the time Purchaser wishes
to sell the Shares there may be no public market upon which to make such a sale,
and that, even if such a public market then exists the Company may not be
satisfying the current public information requirements of Rule 144, and that, in
such event, Purchaser will be precluded from selling the Shares under Rule 144
even if the two-year minimum holding period had been satisfied.

                                      -3-
<PAGE>

          (f)  Purchaser further understands that in the event all of the
applicable requirements of Rule 701 and Rule 144 are not satisfied, registration
under the Securities Act, compliance with Regulation A or some other
registration exemption will be required; and that, notwithstanding the fact that
Rule 701 and Rule 144 are not exclusive, the staff of the Securities and
Exchange Commission has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 701 and Rule 144 will have a substantial burden of proof
in establishing that an exemption from registration is available for such offers
or sales and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

     5.   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):

          (a) "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.  NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR
THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
1933."

          (b) "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."

          (c) Any legend required to be placed thereon by the California
Commissioner of Corporations.

     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, for any reason, with or
without cause.

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

          (a) Governing Law.  This Agreement and all acts and transactions

writing signed by the parties to this Agreement. The failure by either party to
enforce any rights under this Agreement shall not be construed as a waiver of
any rights of such party.

          (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 (x) such
provision shall be excluded from this Agreement, (y) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (z) the
balance of the Agreement shall be enforceable in accordance with its terms.

          (d)  Construction.  This Agreement is the result of negotiations

                        [HAMBRECHT & QUIST LETTERHEAD]

March 22, 1999

Albert Greene
President and Chief Executive Officer
HealthCentral, Inc.
2600 Tenth Street
Berkeley, CA 94710

Dear Al:

Hambrecht & Quist LLC ("Hambrecht & Quist" or the "Placement Agent") is pleased
to represent HealthCentral.com ("HealthCentral" or the "Company") as its
exclusive placement agent in connection with the proposed private placement of a
new issue of preferred stock or a similar financial security (the "Securities").
This letter sets forth the terms and conditions under which the Company and
Hambrecht & Quist agree to work in connection with the proposed sale of the
Securities.

Exclusive Agency; Best Efforts

Hambrecht & Quist will use its best efforts to place approximately $15.0 million
of the Securities at a price to which the Company and Hambrecht & Quist shall
mutually agree. The Company will not offer any of the Securities for sale to, or
solicit any offers to buy from, any person or persons, whether directly or
indirectly, otherwise than through Hambrecht & Quist; provided, however, that
under no circumstances shall Hambrecht & Quist be liable for failure to obtain
or produce the proposed financing.

Fees and Expenses

The Company will pay Hambrecht & Quist an initial retainer of $25,000 upon
receiving an appropriate amount of bridge financing to be mutually agreed upon
by the Company and Hambrecht & Quist. This retainer is nonrefundable but shall
be credited against any further fees payable to Hambrecht & Quist as part of
this engagement. In addition, the Company will promptly reimburse Hambrecht &
Quist upon request for all of its reasonable out-of-pocket expenses, including
the reasonable fees and expenses of counsel to the Placement Agent not in excess
of $35,000. As is customary in private placements, the Company will also pay the
fees and expenses of one counsel for the purchasers of the Securities up to a
maximum amount which shall be agreed between the Company and the lead
purchasers. Finally, the Company agrees to indemnify Hambrecht & Quist in
accordance with the Standard Form of Indemnification Agreement set forth as
Exhibit A hereto.

As compensation for its services as Placement Agent hereunder, the Company will
pay to Hambrecht & Quist at each closing for the sale of Securities a cash fee
to 6.0% of the value of the Securities sold at such closing, together with
warrants equal in value to 2.0% of the Securities sold at such closing;
provided, however, that the minimum aggregate cash consideration, if any, to be
paid to Hambrecht & Quist in connection with this engagement shall not be less
than $350,000.

In the event the Company enters into a strategic transaction involving a
significant portion of the equity of the Company instead of, or in addition to,
completing the proposed private placement, the Company agrees to pay Hambrecht &
Quist a cash fee for its services equal to the greater of (i) the fee Hambrecht
& Quist would have earned for the proposed private placement (subject to the
limitations contained in this letter) or (ii) a fee for acting as financial
advisor to the Company in connection with such strategic transaction (such fee
to be consistent with market practice for such services when provided by
nationally recognized investment banking firms).

Confidential Private Placement Memorandum

The Company hereby authorizes the Placement Agent to transmit to the prospective
purchasers of the Securities a Confidential Private Placement Memorandum with
attached exhibits and such supplements as may from time to time be prepared or
approved by the Company (collectively, the "Memorandum"). The Memorandum will
contain information and financial data concerning the Company and will be
prepared, reviewed, and approved by the management of the Company. The documents
comprising the Memorandum are
<PAGE>

the only documents that are to be delivered to the prospective purchasers by
Hambrecht & Quist and the Company in connection with the offering of the
Securities.

The Company agrees that the Memorandum will not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. The Company will advise Hambrecht & Quist
immediately of the occurrence of any event or any other change known to the
Company which results in the Memorandum containing an untrue statement of a
material fact or omitting to state a material fact required to be stated therein
or necessary to make the statements contained therein, in light of the
circumstances under which they were made, not misleading. The Company agrees
that Hambrecht & Quist shall be entitled to rely upon all reports of the Company
and information, whether written or oral, supplied to Hambrecht & Quist by or on
behalf of the Company, and Hambrecht & Quist shall not in any respect to be
responsible for the accuracy or completeness of any such report or information
or assume any obligation to verify the same. Hambrecht & Quist will not make any
representation to any person which is materially different from the information
contained in the Memorandum.

Termination

This agreement may be terminated by the Company or Hambrecht & Quist, with or
without cause, effective 5 days following receipt by the non-terminating party
of written notice of such termination. Any such termination shall not (except as
otherwise provided herein) affect the compensation, reimbursement, right of
first refusal or indemnification provisions set forth herein, all of which will
remain in full force and effect. In addition, if any person introduced to the
Company by Hambrecht & Quist during the term of this engagement purchases
Securities during the 9-month period following termination of this agreement,
the Company shall pay Hambrecht & Quist upon the closing of such sale, a cash
fee equal to the amount of the cash fee that would be payable had this agreement
not been terminated.

Miscellaneous

Notwithstanding its engagement as placement agent hereunder, Hambrecht & Quist
may not, without its prior written consent, be quoted or referred to in any
document, release or communication prepared, issued or transmitted by the
Company (including any entity controlled by, or under common control with, the
Company and any director, officer, employee or agent thereof).

Following completion of this engagement, Hambrecht & Quist shall have the right
to place advertisements in financial and other newspapers and journals at its
own expense describing its services to the Company hereunder.

This agreement shall be binding upon the Company, Hambrecht & Quist and their
respective successors and assigns and shall be governed and construed in
accordance with the laws of the State of California without giving effect to the
conflicts of laws principles thereof.

If the foregoing correctly sets forth our understanding, please so indicate by
executing this letter, together with the enclosed duplicate originals, in the
space indicated and returning two (2) of these originals for our files. By so
doing, the Company represents and warrants that it has obtained, or within 15
calendar days will obtain, Board of Directors' or other approval of this
agreement necessary to cause this agreement to be duly authorized, executed and
delivered by the Company.

                             HAMBRECHT & QUIST LLC

                  Standard Form of Indemnification Agreement

The following provisions regarding indemnification are an integral part of the
letter agreement (the "Letter Agreement") to which they are attached between
Hambrecht & Quist LLC (the "Placement Agent") and the Company named therein.
Capitalized terms used but not defined below have the meanings given to them in
the Letter Agreement.

Indemnification by the Company

In connection with the services which the Placement Agent has agreed to render
to the Company in the Letter Agreement, the Company shall indemnify the
Placement Agent, each of its directors, officers, employees, and agents and each
person, if any, who controls the Placement Agent within the meaning of Section
15 of the Securities Act of 1933, as amended (the "Act") (collectively, the
Placement Agent), and hold the Placement Agent harmless to the fullest extent
permitted by law against any and all losses, claims, damages, and liabilities
(and actions in respect thereof) to which the Placement Agent may become subject
in connection with (i) the Placement Agent's use of information contained in the
Memorandum that is materially inaccurate or alleged to be materially inaccurate
in any respect (as a result of misrepresentation, omission, failure to update or
otherwise) that is provided to the Placement Agent by the Company or its
representatives, agents, or advisors, regardless of whether the Placement Agent
knew or should have known of such inaccuracy, (ii) the breach of any
representation, warranty or covenant of the Company contained in the Letter
Agreement, or (iii) any other aspect of the rendering by the Placement Agent of
services under the Letter Agreement, unless it is finally judicially determined
that losses, claims, damages, or liabilities relating thereto were incurred
solely as a result of the bad faith, intentional wrongdoing or willful
misconduct of the Placement Agent. Notwithstanding the foregoing, the Company
shall not be required to indemnify the Placement Agent for matters for which the
Company is indemnified by the Placement Agent hereafter.

Indemnification by the Placement Agent

The Placement Agent shall indemnify the Company and each person, if any, who
controls the Company within the meaning of Section 15 of the Act, and hold such
person harmless to the fullest extent permitted by law, against any and all
losses, claims, damages, and liabilities (and actions in respect thereof) to
which such person may become subject if such loss, claim, damage, liability or
action arises out of or is based upon (i) any untrue statement of a material
fact contained in the Memorandum (as amended or supplemented) or the omission to
state therein a material fact necessary to make the statements therein not
misleading, but in each case only to the extent that the untrue statement or
omission was made in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Placement Agent specifically for
inclusion therein, or (ii) any known violation by the Placement Agent of the
provisions of Rule 502(c) of Regulation D.

Notice of Indemnification

Each party hereto agrees that, upon the service of a summons or other initial
legal process upon it in any action or suit instituted against it, or upon
receipt of written notification of the commencement of any investigation or
inquiry of, or proceeding against, it in respect of which indemnify may be
sought hereunder, it will promptly give written consent notice (the "Notice") of
such service or notification to the party or parties from whom indemnification
may be sought hereunder. No indemnification otherwise provided for hereunder
shall be available to any party who shall fail so to give the notice if the
party to whom such Notice was not given was unaware of the action, suit,
investigation, inquiry or proceeding to which the Notice would have related and
was prejudiced by the failure to give the Notice, but the omission so to notify
such indemnifying party or parties of any such service or notification shall not
relieve such indemnifying party or parties from any liability which it or they
may have to the indemnified party for contribution or otherwise than on account
of such indemnify agreement.

Defense by Indemnifying Party

Any indemnifying party shall be entitled at its own expense to participate in
the defense of any action, suit or proceeding against, or investigation or
inquiry of, an indemnified party. Any indemnifying party shall be entitled, if
it so elects by giving written notice (the "Notice of Defense") to the
indemnified party within a reasonable time after receipt of the Notice, to
assume (alone or in conjunction with any other indemnifying party or parties)
the entire defense of such action, suit, investigation, inquiry or

                                       4
<PAGE>

proceedings, in which event such defense shall be conducted at the expense of
the indemnifying party or parties, by counsel chosen by such indemnifying party
or parties and reasonably satisfactory to the indemnified party or parties;
provided, however, that (i) if the indemnified party or parties reasonably
determine that there may be a conflict between the positions of the indemnifying
party or parties and of the indemnified party or parties in conducting the
defense of such action, suit, investigation, inquiry or proceeding or that there
may be legal defenses available to such indemnified party or parties different
from or in addition to those available to the indemnifying party or parties,
then counsel for the indemnified party or parties shall be entitled to conduct
the defense to the extent reasonably determined by such counsel to be necessary
to protect the interests of the indemnified party or parties, and (ii) in any
event, the indemnified party or parties shall be entitled to have counsel chosen
by such indemnified party or parties participate in, but not conduct, the
defense.

If, within a reasonable time after receipt of the Notice, an indemnifying party
gives a Notice of Defense, and counsel chosen by the indemnifying party or
parties is reasonable satisfactory to the indemnified party or parties, the
indemnifying party or parties will not be liable for any legal or other expenses
subsequently incurred by the indemnified party or parties in connection with the
defense of the action, suit, investigation, inquiry or proceeding, except that
(x) the indemnifying party or parties shall bear the legal and other expenses
incurred in connection with the conduct of the defense as referred to in clause
(i) of the proviso to the preceding paragraph, and (y) the indemnifying party or
parties shall bear such other expenses as it or they have authorized to be
incurred by the indemnified party or parties. If, within a reasonable time after
the receipt of the Notice, no Notice of Defense has been given, the indemnifying
party or parties shall be responsible for any legal or other expenses incurred
by the indemnified party or parties in connection with the defense of the
action, suit, investigation, inquiry or proceeding. The indemnifying party shall
not be liable for settlement of any such action effected without its written
consent, but if settled with its written consent, or if there be a final
judgment for the plaintiff in any such action, the indemnifying party shall
indemnify with respect to such settlement or judgment.

Contribution if Indemnification Not Available

If for any reason the foregoing indemnity is unavailable to the indemnified
party or insufficient to hold the indemnified party harmless, then the
indemnifying party shall contribute to the amount paid or payable by the
indemnified party as a result of such claims, liabilities, losses, damages or
expenses, in such proportions as is appropriate to reflect not only the relative
benefits received by the indemnifying party, on the one hand, and the
indemnified party, on the other hand, but also the relative fault of the
indemnifying party and the indemnified party, as well as any relevant equitable
considerations. Notwithstanding any contrary provisions in this agreement, the
aggregate contribution of the Placement Agent to all claims, liabilities,
losses, damages, and expenses shall not exceed the amount of fees actually
received by the Placement Agent pursuant to its engagement by the Company. It is
hereby further agreed that the relative benefits to the Company, on the one
hand, and Placement Agent, on the other hand, with respect to the transaction
contemplated in the Letter Agreement shall be deemed to be in the same
proportion as (i) the net proceeds actually received by the Company resulting
from the sale of the Securities bears to (ii) the fees paid to Placement Agent
with respect to such sale. The indemnifying party agrees that its
indemnification commitments herein set forth shall apply whether or not the
indemnified party is a formal party to any such actions or proceedings, that
such commitments shall be in addition to any liability that the indemnifying
party may have to the indemnified party at common law or otherwise, and that
such commitments shall survive any termination of the Letter Agreement.

Survival and Effect

This indemnity agreement and the representations and warranties of the parties
contained in the Letter Agreement shall remain in full force and effect
regardless of any investigation made by or on behalf of the Placement Agent, and
shall survive any termination of such Letter Agreement or the issuance and
delivery of the Securities.

                                  BACKGROUND
                                  ----------

         This Agreement is entered into in connection with and is ancillary to
an Agreement and Plan of Reorganization (the "Plan") dated as of May 6, 1999
                                              ----
among Parent, HC Acquisition Corp., a Delaware corporation and wholly owned
subsidiary of Parent ("Merger Sub"), and Windom Health Enterprises, a California
                       ----------
corporation ("Company"), pursuant to which the Company is to merge with and into
              -------
Merger Sub, Merger Sub will continue as the surviving corporation in the merger,
and the shares of Company capital stock outstanding immediately prior to the
effective time of the merger will be converted into shares of Parent Common
Stock, all as set forth in the Plan (the "Merger"). The date on which the Merger
                                          ------
becomes effective will be the effective date of this Agreement (the "Effective
                                                                     ---------
Date").

         Consultant is the majority shareholder and Chairman of the Board of
Company and has been actively involved in the development and/or marketing of
Company's products. Parent intends to continue the business of Company after the
Merger and integrate such business into Parent's ongoing business as a
subsidiary of Parent. To preserve and protect the assets of Company, including
Company's goodwill, customers and trade secrets of which Consultant has and will
have knowledge in his or her role as an employee of Parent and to preserve and
protect Parent's goodwill and business interests going forward, and in
consideration for Parent's entering into and performing under the Plan,
Consultant has agreed to enter into this Agreement. Parent and Consultant have
entered into a Consulting Agreement (the "Consulting Agreement") concurrently
                                          --------------------
with execution of this Agreement.

         Consultant and Parent believe the limitations as to time, geographical
area and scope of activity contained in this Agreement are reasonably necessary
to, and no greater than that required to, protect the goodwill and business
interests of Parent.

               1. For the period beginning on the Effective Date and ending on
the three-year anniversary of the Effective Date, Consultant will not
individually or as an employee, consultant, partner, officer, director or
shareholder or in any other capacity whatsoever (including through GHI) of or
for any person, firm, partnership, company or corporation other than Parent or
its subsidiaries, work as an employee or consultant, sell products or services
to, or own, manage, operate, sell, control or participate in the ownership,
management, operation, sales or control of any business engaged, in the
geographical areas referred to in Section 3 below, in the provision of health
information, products and services directly to the general public (including
linkages between consumers and health providers, payors and ancillary entities)
in various media, including but not limited to radio, television, internet,
interactive television, interactive cable and satellite (the "Restricted
                                                              ----------
Business").
- --------
<PAGE>

               2.   For the period beginning on the Effective Date and ending 36
months thereafter, Consultant shall not directly or indirectly solicit, induce,
recruit or encourage any of Parent's employees or consultants to terminate their
relationship with Parent, or attempt any of the foregoing, either for the
benefit of Consultant or any other person or entity. For the period beginning on
the Effective Date and ending 36 months thereafter, Consultant shall not solicit
any licensor to or customer of the Parent or licensee of the Parent's products
that are known to Consultant with respect to any Restricted Business.

               3.   The geographical areas in which the restrictions provided
for in this Agreement apply include all cities, counties and states of the
United States, and all other countries in which Parent or Company has engaged in
sales or otherwise conducted business or selling or licensing efforts in any
aspect of the Restricted Business at any time prior hereto or during the term of
this Agreement. Consultant acknowledges that the scope and period of
restrictions and the geographical area to which the restrictions imposed in this
Section 3 applies are fair and reasonable and are reasonably required for the
protection of Parent and that this Agreement accurately describes the business
to which the restrictions are intended to apply.

               4.   Consultant acknowledges that any breach of the covenants of
this Agreement will result in immediate and irreparable injury to Parent and,
accordingly, consents to the application of injunctive relief and such other
equitable remedies for the benefit of Parent as may be appropriate in the event
such a breach occurs or is threatened. The foregoing remedies will be in
addition to all other legal remedies to which Parent may be entitled hereunder,
including, without limitation, monetary damages.

               5.   Termination. Notwithstanding any provision in this Agreement
                    -----------
to the contrary, either party may at any time terminate the Consulting Agreement
between Parent and Consultant of even date herewith (the "Consulting Agreement")
                                                          --------------------
and all obligations thereunder, in which case this Agreement shall terminate in
its entirety and be of no further force or effect, provided however that if the
                                                   ----------------
Company terminates Consultant's Consultancy (as defined in the Consulting
Agreement) for Cause (as defined in the Consulting Agreement), then,
notwithstanding anything to the contrary in this Section 5, this Agreement shall
remain in full force and effect..

               6.   Miscellaneous.

                         ----------
agreement and supersedes and replaces all prior agreements between Parent and
Consultant or Company and Consultant concerning the subject matter hereof. This
Agreement may not be changed or modified in whole or in part except by a writing
signed by the party against whom enforcement of the change or modification is
sought.

                    (c)  Successors and Assigns. This Agreement will not be
                         ----------------------
assignable by either Consultant or Parent, except that the rights and

interpreted according to the substantive laws of the State of California without
regard to such state's conflicts law.

                    (e)  No Waiver. The failure of either party to insist on
                         ---------
strict compliance with any of the terms of this Agreement in any instance or
instances will not be deemed to be a waiver of any term of this Agreement or of
that party's right to require strict compliance with the terms of this Agreement
in any other instance.

                    (f)  Severability. It is the intent of the parties that the

contained herein are reasonably and properly required for the adequate
protection of the interests of Parent. If for any reason a court of competent
jurisdiction or binding arbitration proceeding finds any provision of this
Agreement, or the application thereof, to be invalid or unenforceable, this
Agreement will be deemed amended to revise that provision or portion to the
minimum extent necessary to render it enforceable. Such amendment will apply
only with respect to the operation of this paragraph in the particular
jurisdiction in which such adjudication was made, and the remaining provisions
of this Agreement will be interpreted so as best to reasonably effect the intent
of the parties. The parties further agree that the court or arbitrator shall
replace any such invalid or unenforceable provisions with valid and enforceable
provisions designed to achieve, to the extent possible, the business purposes
and intent of such unenforceable provisions.

                    (h)  Dispute Resolution. To the fullest extent permitted by
                         ------------------
law, any dispute, claim or controversy of any kind (including but not limited to
tort, contract and statute) arising under, in connection with, or relating to
this Agreement or Consultant's employment, shall be resolved exclusively by
binding arbitration in Alameda County, California in accordance with the
commercial rules of the American Arbitration Association then in effect. Parent
and Consultant agree to waive any objection to personal jurisdiction or venue in
any forum located in Alameda County, California. No claim, lawsuit or action of
any kind may be filed by either party to this Agreement (other than to enforce
any such arbitration); arbitration is the exclusive dispute resolution mechanism
between the parties hereto. Judgment may be entered on the arbitrator's award in

                                           ----
among Parent, HC Acquisition Corp., a Delaware corporation and wholly owned
subsidiary of Parent ("Merger Sub"), and Windom Health Enterprises, a California
                       ----------
corporation ("Company"), pursuant to which Company is to merge with and into
              -------
Merger Sub, Merger Sub will continue as the surviving corporation in the merger,
and the shares of Company capital stock outstanding immediately prior to the
effective time of the merger will be converted into shares of Parent Common
Stock, all as set forth in the Plan (the "Merger"). The date on which the Merger
                                          ------
becomes effective will be the effective date of this Agreement (the "Effective
                                                                     ---------
Date").
- ----

     Employee is V.P., Engineering of Company and has been actively involved in
the development and/or marketing of Company's products. Parent intends to
continue the business of Company after the Merger and integrate such business
into Parent's ongoing business as a subsidiary of Parent.

     Employee acknowledges and agrees that, prior to or concurrently with the
execution of this Agreement, Employee has terminated, or will terminate,
Employee's employment agreement dated 11/1/95 between the Company and Employee
(the "Windom Employment Agreement"), and that neither the Company, the Merger
      ---------------------------
Sub or Parent will have any obligations under the Windom Employment Agreement,
including but not limited to the obligation to issue Employee any options to
purchase shares, or shares of capital stock, of Parent.

     To preserve and protect the assets of Company, including Company's
goodwill, customers and trade secrets of which Employee has and will have
knowledge in Employee's role as an employee of Parent and to preserve and
protect Parent's goodwill and business interests going forward, and in
consideration for Parent's entering into and performing under the Plan, Employee
has agreed to enter into this Agreement.

     In addition, as required by and defined in Section 5 below, Employee is
concurrently herewith entering into a Proprietary Information and Non-
Solicitation Agreement in favor of Parent designed to protect Parent's
proprietary rights.

     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements
of the parties contained herein, Parent and Employee hereby agree as follows:

     1.  Duties. Employee will be employed as a full-time employee of Parent and
         ------
initially will serve as V.P., Engineering, and agrees to perform such services
as are commensurate with such a position and as may be required or directed by
the Chief Executive
<PAGE>

Officer of Parent. Employee agrees to perform such other duties and
responsibilities as may be reasonably required of him by the Chief Executive
Officer of Parent. Employee agrees that, to the best of Employee's ability and
experience, Employee will at all times conscientiously perform all of the duties
and obligations assigned to Employee in accordance with this Agreement.

hereafter be consented to by Parent in its sole discretion, Employee will not
engage in any other business or render any commercial or professional services,

compensation or otherwise, provided that Employee may (i) provide incidental
assistance to family members on matters of family business, and (ii) sit on the
boards of charitable and nonprofit organizations which do not compete with
Parent, provided in each case that such activities do not conflict with or
interfere with Employee's obligations to Parent. Employee may make personal
investments in nonpublicly traded corporations, partnerships or other entities,
which do not at the time of such investment provide health information, products
and services directly to the general public (including linkages between
consumers and health providers, payors and ancillary entities) in various media,
including but not limited to radio, television, Internet, interactive
television, interactive cable and satellite (the foregoing description of

a part of this Agreement.

     6.   Termination. Employee's employment with the Company will be on an "at

         c.  Acceleration of Vesting in Event of Change of Control.
             -----------------------------------------------------

             (i)     Definition of Change of Control. A "Change of Control"
                     -------------------------------     -----------------
means an acquisition of HealthCentral.com, whether by merger (except for a
merger effected solely for the purpose of changing the domicile of
HealthCentral.com) or any other transaction or series of related transactions in
which the shareholders of HealthCentral.com immediately prior thereto own less
than 50% of the outstanding shares of capital stock of HealthCentral.com (or its
successor or parent) immediately thereafter.

             (ii)    Acceleration Upon Change of Control. Upon the closing of a
                     -----------------------------------
Change of Control, fifty percent (50%) of your options to purchase Common Stock
of HealthCentral.com and/or shares of restricted stock of HealthCentral.com that
are unvested as of the date of the Change of Control (the "Unvested Shares")
                                                           ---------------
shall immediately become vested.

             (iii)   Vesting of Remaining Unvested Shares. Upon a change of
                     ------------------------------------
Control, the remainder of the Unvested Shares for which vesting was not
accelerated pursuant to Section 5 (c)(ii) shall continue to vest at the same
monthly rate as prior to the Change of Control (i.e., if 200 shares vested per
month prior to the Change of Control, the remaining Unvested Shares will
continue to vest at a rate of 200 shares per month after the Change of Control)
and in accordance with the applicable stock option or restricted stock purchase
agreement.

             (iv)    Acceleration of Vesting on Termination Following A change
                     ---------------------------------------------------------
of Control. If HealthCentral.com (or its successor or parent) terminates you
- ----------
without Cause (as defined below) within twelve months after a Change of Control,
then the remaining Unvested Shares shall immediately become vested on such
termination date.

             (iv)    Effects on Pooling Accounting. Notwithstanding anything to
                     -----------------------------
the contrary in this Section 5, if such potential vesting acceleration would
cause a contemplated Change of Control transaction that was intended to be
accounted for as a "pooling-of-interests" transaction to become ineligible for
                    --------------------
such accounting treatment under generally accepted accounting principles, as
determined by HealthCentral.com's independent public accountants prior to the
Change of Control, the vesting of such shares and/or options shall not be so
accelerated.

weeks X 40 hours) or 5 hours, each pay period.

     7.  Confidential Information and Invention Assignment Agreement. Your

acceptance of this offer and commencement of employment with HealthCentral.com

provision were so excluded and (iii) the balance of the Agreement shall be
enforceable in accordance with its terms.

Ladies and Gentlemen:

          Pursuant to a Common Stock Purchase Agreement dated August 30, 1996,
HealthCentral.com (the "Company") sold and issued 1,844,000 shares of its Common
                        -------
Stock (the "Shares") to Dr. Dean Edell ("the Shareholder").  The Company and the
            ------                       ---------------
Shareholder recognize that, in order to provide the Company with an enhanced
opportunity to raise additional capital for the benefit of all shareholders,
including of the Shareholder, it is necessary and appropriate for the
Shareholder to agree to subject 50% of the Shares, or 922,000 shares of Common
Stock (as adjusted for any future stock splits, combinations, recapitalizations
and the like) (the "Locked-Up Securities"), to certain restrictions on transfer.
                    --------------------

          The Shareholder understands that certain investors (the "New
                                                                   ---
Investors") are simultaneously entering into a Series B Preferred Stock Purchase
- ---------
Agreement with the Company (the "Purchase Agreement") of even date herewith
                                 ------------------
pursuant to which the Company desires to sell to the New Investors and the New
Investors desire to purchase from the Company shares of the Company's Series B
Preferred Stock. A condition to the New Investors' obligations under the
Purchase Agreement is that the Company and the Shareholder enter into this
agreement (this "Letter") in which the Shareholder agrees to subject the Locked-
                 ------
Up Securities to certain restrictions on transfer as described below.

          In consideration of the execution of the Purchase Agreement by the New
Investors, and for other consideration, the sufficiency of which is hereby
acknowledged, the Shareholder agrees that, for a period beginning upon the date
hereof and ending upon the earlier of (i) two years from the date hereof, or
(ii) one year after the consummation of a firm commitment public offering by the
Company of its shares of Common Stock under the Securities Act of 1933, as
amended  (the "Lock-Up Period"), without the prior written consent of the
               --------------
Company and the holders of a majority of the shares of the Company's Preferred
Stock (or Common Stock issuable upon conversion thereof) held by the New
Investors then outstanding, the Shareholder will not, directly or indirectly,
offer, sell, contract to sell, grant any option or warrant for the sale of,
register, or otherwise transfer, dispose of, loan, pledge or grant any rights
with respect to (any one of which being referred to herein as a "Disposition")
                                                                 -----------
the Locked-Up Securities.  The foregoing restriction is expressly agreed to
preclude the Shareholder from
<PAGE>

engaging in any hedging or other transaction which is designed to or reasonably
expected to lead to or result in a Disposition of the Locked-Up Securities
during the Lock-Up Period, even if such Locked-Up Securities would be disposed
of by someone other than the Shareholder. The lock-up restriction described in
this paragraph shall not apply to: (a) the 922,000 shares (as adjusted for any
future stock splits, combinations, recapitalizations and the like) currently
held of record by the Shareholder that are not considered Locked-Up Securities
pursuant to this Letter, (b) transactions relating to securities acquired in
open market transactions during the Lock-Up Period, (c) bona fide gifts,
provided the donee or donees thereof agree to be bound by this Lock-Up
Agreement, or (d) dispositions to any trust for the direct or indirect benefit
of the Shareholder or the immediate family of the Shareholder, provided that
such trust agrees in writing to be bound by the terms of this Letter.

          The Shareholder agrees and consents to the entry of stop transfer
instructions with the transfer agent for the Company's capital stock against any
transfer of shares of capital stock of the Company in contravention of the
restrictions set forth above.  The Shareholder confirms that it understands that
the New Investors and the Company will rely upon the representations set forth
in this letter in proceeding with the sale of the Series B Preferred Stock under
the Purchase Agreement.

          The Shareholder hereby represents and warrants that the Shareholder
has full power and authority to enter into this Letter, and that, upon request,
the Shareholder will execute any additional documents necessary or desirable in
connection with the enforcement hereof.  The Shareholder understands and
acknowledges that the restrictions set forth in this Letter serve as additional
restrictions on transfer for the Locked-Up Securities, and do not diminish in
any way the restrictions agreed to by the Shareholder and imposed upon the
securities held by the Shareholder in Section 1.14 of the First Amended and
Restated Investors' Rights Agreement between the Company and certain investors,
including the Shareholder, and the restrictions agreed to by the Shareholder and
imposed upon the securities held by the Shareholder in Section 3(f) of the
Common Stock Purchase Agreement between the Company and the Shareholder, or any
other restriction on transfer which the Shareholder may agree to be bound by in
the future.  This Letter may be executed in counterparts.

     The Shareholder has executed this Letter as of the day and year first set

                               HEALTHCENTRAL.COM

                          CHANGE OF CONTROL AGREEMENT


     This Change of Control Agreement (this "Agreement") is made and entered
                                             ---------
into by and between Albert L. Greene (the "Employee") and HealthCentral.com, a
                                           --------
California corporation (the "Company"), effective as of ______________, ____.
                             -------

                                   RECITALS

     A.   It is expected that the Company from time to time will consider the
possibility of an acquisition by another company or other change of control.
The Board of Directors of the Company (the "Board") recognizes that such
                                            -----
consideration can be a distraction to the Employee and can cause the Employee to
consider alternative employment opportunities. The Board has determined that it
is in the best interests of the Company and its stockholders to assure that the
Company will have the continued dedication and objectivity of the Employee,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Company.

     B.   The Board believes that it is in the best interests of the Company and
its stockholders to provide the Employee with an incentive to continue his or
her employment and to motivate the Employee to maximize the value of the Company
upon a Change of Control for the benefit of its stockholders.

     C.   The Board believes that it is imperative to provide the Employee with
certain benefits, upon a Change of Control and upon Employee's termination of
employment thereafter, that provide the Employee with enhanced financial
security and incentive and encouragement to the Employee to remain with the
Company notwithstanding the possibility of a Change of Control.

     D.   Certain capitalized terms used in this Agreement are defined in
Section 6 below.

     The parties hereto agree as follows:

     1.   TERM OF AGREEMENT.  This Agreement shall terminate upon the date that
all obligations of the parties hereto with respect to this Agreement have been
satisfied.

     2.   AT-WILL EMPLOYMENT.  The Company and the Employee acknowledge that the
Employee's employment is and shall continue to be at-will, as defined under
applicable law.  If the Employee's employment terminates for any reason,
including (without limitation) any termination prior to a Change of Control, the
Employee shall not be entitled to any payments, benefits, damages, awards or
compensation other than as provided by this Agreement or as may otherwise be
available in accordance with the Company's established employee plans and
practices or pursuant to other agreements with the Company.
<PAGE>

     3.   CHANGE OF CONTROL.

          (a)  Acceleration Upon Change of Control.  Upon a Change of Control,
fifty percent (50%) of the Employee's options to purchase Common Stock of the
Company and/or shares of restricted stock of the Company that are unvested as of
the date of the Change of Control (the "Unvested Shares") shall immediately
                                        ---------------
become vested.

          (b)  Vesting of Remaining Unvested Shares.  Upon a Change of Control,
the remainder of the Unvested Shares for which vesting was not accelerated
pursuant to Section 3(a) shall continue to vest at the same monthly rate as
prior to the Change of Control (i.e., if 200 shares vested per month prior to
the Change of Control, the remaining Unvested Shares will continue to vest at
the rate of 200 shares per month after the Change of Control) and in accordance
with the applicable stock option or restricted stock purchase agreement.

          (c)  Termination Following a Change of Control.  If the Employee's
employment terminates as a result of Involuntary Termination other than for
Cause at any time within 12 months following a Change of Control, then, subject
to Section 4, all of the remaining Unvested Shares then held by the Employee
shall automatically be accelerated in full so as to become completely vested as
of the date of such Involuntary Termination.

          (d)  Pooling of Interests. Notwithstanding any other provision of this
Agreement, in the event that any potential vesting acceleration pursuant to the
foregoing Sections 3(a), (b) or (c) would cause a contemplated Change of Control
transaction that was intended to be accounted for as a "pooling-of-interests"
transaction to become ineligible for such accounting treatment under generally
accepted accounting principles, as determined by the Company's independent
public accountants (the "Accountants") prior to the Change of Control,
Employee's stock options and restricted stock shall not have their vesting so
accelerated.

          (e)  Voluntary Resignation; Termination For Cause. If the Employee's
employment terminates by reason of the Employee's voluntary resignation (and is
not an Involuntary Termination), or if the Employee is terminated for Cause,
then the Employee shall not be entitled to receive any benefits except for those
(if any) as may then be established under the Company's then existing severance
and benefits plans and practices or pursuant to other agreements with the
Company.

          (f)  Disability; Death. If the Company terminates the Employee's
employment as a result of the Employee's Disability, or such Employee's
employment is terminated due to the death of the Employee, then the Employee
shall not be entitled to receive any benefits except for those (if any) as may
then be established under the Company's then existing severance and benefits
plans and practices or pursuant to other agreements with the Company.

          (g)  Termination Apart from Change of Control.  In the event the
Employee's employment is terminated for any reason, either prior to the
occurrence of a Change of Control or after the twelve-month period following a
Change of Control, then the Employee shall not be entitled to receive any
benefits except for those (if any) as may then be established
<PAGE>

under the Company's existing severance and benefits plans and practices or
pursuant to other agreements with the Company.

     4.   LIMITATION ON PAYMENTS.  In the event that the any of the Employee's
benefits provided for in this Agreement or otherwise payable to the Employee (i)
constitute "parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code"), and (ii) but for this
Section 4, 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
benefits shall be either

          (a)  delivered in full, or

          (b)  delivered as to such lesser extent which would result in no
portion of such benefits being subject to excise tax under Section 4999 of the
Code, whichever of the foregoing amounts, taking into account the applicable
federal, state and local income taxes and the excise tax imposed by Section
4999, results in the receipt by the Employee on an after-tax-basis, of the
greater amount of benefits, notwithstanding that all or some portion of such
benefits may be taxable under Section 4999 of the Code. Unless the Company and
the Employee otherwise agree in writing, any determination required under this
Section 4 shall be made in writing by the Accountants, whose determination shall
be conclusive and binding upon the Employee and the Company for all purposes.
For purposes of making the calculations required by this Section 4, the
Accountants may make reasonable assumptions and approximations concerning
applicable taxes and may rely on reasonable, good faith interpretations
concerning the application of Sections 280G and 4999 of the Code. The Company
and the Employee shall furnish to the Accountants such information and documents
as the Accountants may reasonably request in order to make a determination under
this Section. The Company shall bear all costs the Accountants may reasonably
incur in connection with any calculations contemplated by this Section 4. In the
event that subsection (a) above applies, then Employee shall be responsible for
any excise taxes imposed with respect to such benefits. In the event that
subsection (b) above applies, then each benefit provided hereunder shall be
proportionately reduced to the extent necessary to avoid imposition of such
excise taxes.

     5.   DEFINITION OF TERMS.  The following terms used in this Agreement shall
have the following meanings:

          (a)  "Cause" shall mean (i) gross negligence or willful misconduct in
                -----
the performance of the Employee's duties to the Company; (ii) repeated
unexplained or unjustified absence from the Company; (iii) a material and
willful violation of any federal or state law or any agreement with the Company;
(iv) refusal or failure to act in accordance with any specific direction or
order of the Company; (v) commission of any act of fraud with respect to the
Company; or (vi) conviction of a felony or a crime involving moral turpitude
causing material harm to the standing and reputation of the Company, in each
case as determined by the Board of Directors of the Company.
<PAGE>

          (b)  "Change of Control" means the consummation of any of the
                -----------------
following events:

               (i)    the sale of all or substantially all of the assets of the
Company; or

               (ii)   a merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the
voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) at least fifty percent (50%) of
the total voting power represented by the voting securities of the Company or
such surviving entity outstanding immediately after such merger or
consolidation; or

               (iii)  a tender or exchange offer or other transaction or series
of transactions resulting in less than a majority of the outstanding voting
shares of the surviving corporation being held, immediately after such
transaction or series of transactions, by the holders of the voting shares of
the Company outstanding immediately prior to such transaction or series of
transactions.

          (c)  "Disability" shall mean that the Employee has been unable to
                ----------
perform his or her Company duties as the result of his or her incapacity due to
physical or mental illness, and such inability, at least 26 weeks after its
commencement, is determined to be total and permanent by a physician selected by
the Company or its insurers and reasonably acceptable to the Employee or the
Employee's legal representative (such Agreement as to acceptability not to be
unreasonably withheld).  Termination resulting from Disability may only be
effected after at least 30 days' written notice by the Company of its intention
to terminate the Employee's employment.  In the event that the Employee resumes
the performance of substantially all of his or her duties hereunder before the
termination of his or her employment becomes effective, the notice of intent to
terminate shall automatically be deemed to have been revoked.

          (d)  "Involuntary Termination" shall mean (i) without the Employee's
                -----------------------
express written consent, the significant reduction of the Employee's duties,
authority or responsibilities, relative to the Employee's duties, authority or
responsibilities as in effect immediately prior to such reduction, or the
assignment to Employee of such reduced duties, authority or responsibilities;
(ii) without the Employee's express written consent, a substantial reduction,
without good business reasons, of the facilities and prerequisites (including
office space and location) available to the Employee immediately prior to such
reduction; (iii) a reduction by the Company in the base salary of the Employee
as in effect immediately prior to such reduction; (iv) a material reduction by
the Company in the kind or level of employee benefits, including bonuses, to
which the Employee was entitled immediately prior to such reduction with the
result that the Employee's overall benefits package is significantly reduced;
(v) the relocation of the Employee to a facility or a location more than thirty
(30) miles from the Employee's then present location, without the Employee's
express written consent; (vi) any purported termination of the Employee by the
Company which is not effected for Disability or for Cause, or any purported
termination for which the grounds relied upon are not valid; (vii) the failure
of the Company to obtain the assumption of this Agreement by any successors
contemplated in Section 6(a) below;
<PAGE>

or (viii) any act or set of facts or circumstances which would, under California
case law or statute, constitute a constructive termination of the Employee.

          (e)  "Termination Date" shall mean (i) if this Agreement is terminated
                ----------------
by the Company for Disability, thirty (30) days after notice of termination is
given to the Employee (provided that the Employee shall not have returned to the
performance of the Employee's duties on a full-time basis during such thirty
(30)-day period), (ii) if the Employee's employment is terminated by the Company
for any other reason, the date on which a notice of termination is given,
provided that if within thirty (30) days after the Company gives the Employee
notice of termination, the Employee notifies the Company that a dispute exists
concerning the termination or the benefits due pursuant to this Agreement, then
the Termination Date shall be the date on which such dispute is finally
determined, either by mutual written agreement of the parties, or by a final
judgment, order or decree of a court of competent jurisdiction (the time for
appeal therefrom having expired and no appeal having been perfected), or (iii)
if this Agreement is terminated by the Employee, the date on which the Employee
delivers the notice of termination to the Company.

     6.   SUCCESSORS.

          (a)  Company's Successors.  Any successor to the Company (whether
direct or indirect and whether by purchase, merger, consolidation, liquidation
or otherwise) to all or substantially all of the Company's business and/or
assets shall assume the obligations under this Agreement and agree expressly to
perform the obligations under this Agreement in the same manner and to the same
extent as the Company would be required to perform such obligations in the
absence of a succession.  For all purposes under this Agreement, the term
"Company" shall include any successor to the Company's business and/or assets
 -------
which executes and delivers the assumption agreement described in this Section
6(a) or which becomes bound by the terms of this Agreement by operation of law.

          (b)  Employee's Successors. The terms of this Agreement and all rights
of the Employee hereunder shall inure to the benefit of, and be enforceable by,
the Employee's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

     7.   NOTICE.

          (a)  General.  Notices and all other communications contemplated by
this Agreement shall be in writing and shall be deemed to have been duly given
when personally delivered or five (5) days after being mailed by U.S. registered
or certified mail, return receipt requested and postage prepaid.  In the case of
the Employee, mailed notices shall be addressed to him or her at the home
address which he or she most recently communicated to the Company in writing.
In the case of the Company, mailed notices shall be addressed to its corporate
headquarters, and all notices shall be directed to the attention of its
Secretary.

          (b)  Notice of Termination.  Any termination by the Company for Cause
or by the Employee as a result of a voluntary resignation and any Involuntary
Termination shall be
<PAGE>

communicated by a notice of termination to the other party hereto given in
accordance with Section 7(a) of this Agreement. Such notice shall indicate the
specific termination provision in this Agreement relied upon, shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination under the provision so indicated, and shall specify the termination
date (which shall be not more than 30 days after the giving of such notice). The
failure by the Employee to include in the notice any fact or circumstance which
contributes to a showing of Involuntary Termination shall not waive any right of
the Employee hereunder or preclude the Employee from asserting such fact or
circumstance in enforcing his or her rights hereunder.

                               HEALTHCENTRAL.COM

                LICENSE AND CONFIDENTIAL INFORMATION AGREEMENT
                ----------------------------------------------

     This License and Confidential Information Agreement is entered into this
14th day of May, 1999 between Dean Edell, M.D. (the "Founder") and
HealthCentral.com, a California corporation (the "Company").

     A.  The Founder is a founding shareholder of the Company and owns 1,844,000
shares of Common Stock of the Company (the "Founder's Shares").  The Company is
engaged in the business of providing health care services, products and
information via the internet and other interactive media, excluding radio and
television (the "Business").

     B.  The Founder owns the trade name, trademark and servicemark "Dr. Dean
Edell" (the "Trademark").  The parties desire that the Company use the
Trademark, as well as Founder's likeness and image (together with Trademark, the
"Name") in connection with the Business and own the Work (as defined below) that
the Founder creates for or provides to the Company.

     Therefore, the parties agree as follows:

     1.  Exclusive License to Use Name in Company's Business.  In consideration
         ---------------------------------------------------
of the rights granted to Founder in Section 5, Founder hereby grants to Company
(including its successors and assigns) an exclusive, worldwide, transferable,
royalty-free right and license (with the right to sublicense) to use and
reproduce the Name solely in connection with the Company's Business. The Company
agrees to maintain the same or improved standards of quality for the
information, services and products that it provides in the Business as those
established and in effect as of the date of this Agreement. The Company
covenants and agrees that it will not intentionally permit, do or commit any act
that would degrade, tarnish or deprecate the Founder or the Founder's public
image in society or standing in the community. Founder hereby represents and
warrants that he has all right, title and interest in the Name.

     2.  Assignment of Work Relating to Company's Business.  During the course
         -------------------------------------------------
of Founder's relationship as a director or advisor of the Company (which
advisory or director relationship between the Company and Founder, whether
commenced prior to or upon the date of this Agreement shall be referred to
herein as the "Relationship"), Founder shall from time to time, and as mutually
               ------------
agreed between Founder and the Company, provide to or create for the Company
articles and other written or electronically transmitted information relating to
the Company's Business (the "Work"). The Founder hereby assigns and agrees to
assign to the Company or its designee, Founder's entire right, title, and
interest throughout the world in and to the Work and all intellectual property
rights thereto. Founder further acknowledges that all Work that is made by
Founder (solely or jointly with others) within the scope of and during the
period of the Relationship is "works made for hire," and that the Company will
be the owner of all copyrights relating to the Work. Founder agrees to perform,
during and after the Relationship, all acts deemed reasonably necessary by the
Company to permit and assist it, at its expense, in obtaining and enforcing the
full benefits, enjoyment, rights and title throughout the world in the Work and
all intellectual property rights thereto.

     3.  Confidentiality Obligation.  Founder agrees to hold in confidence and
         --------------------------
not to use (except in connection with the provision of services as a director or
advisor and in the best interests of the Company) or disclose to any third
person or entity, either during or after the termination of the Relationship,
any Confidential Information Founder obtains or creates during the period of the
<PAGE>

Relationship, whether or not during working hours, until such Confidential
Information becomes generally known by the public. Founder agrees not to make
copies of such Confidential Information except as authorized by the Company.
Upon termination of the Relationship, Founder will return or deliver to the
Company all tangible forms of such Confidential Information in his possession or
control. As used in this Agreement, the term "Confidential Information" means
                                              ------------------------
information pertaining to the Business of the Company disclosed to Founder by
the Company either directly or indirectly in writing, orally or by drawings or
observation of parts or equipment or created by Founder during the Relationship
and relating to the Business.

     4.  No Conflicts.  Founder represents that the performance of all the terms
         ------------
of this Agreement and provision of services as a director and advisor to the
Company does not and will not breach any agreement to keep in confidence
proprietary information, knowledge or data acquired by Founder in confidence or
in trust prior to the Relationship, and Founder will not disclose to the
Company, or induce the Company to use, any confidential or proprietary
information or material belonging to any previous employer or others. Founder
has not entered into, and agrees not to enter into, any written or oral
agreement that conflicts with the provisions of this Agreement.

     5.  Approval of Content and Advertising.  Founder has the right to review
         -----------------------------------
and reasonably approve (within ten business days after receipt) all content and
advertising to be located on the "Dr. Dean" section of the Company's
"HealthCentral.com" web site.  Founder agrees that he will not unreasonably
withhold his consent to the Company's choice of any such content and/or
advertising.

     6.  Competitive Protection. Founder agrees that the Company shall be the
         ----------------------
sole vehicle through which his services will be commercialized in the Internet
field (except for the publication of radio broadcast transcripts over the
Internet, pursuant to an agreement between Founder and Premier Radio Networks,
Inc. dated January 1, 1998). During the term of this Agreement, Founder will not
invest in, or provide any services, including but not limited to services as an
author, host or contributor, or publicity or advertising services to, nor will
Founder participate in the development, production or promotion of any products
or services offered by, any person or entity which the Company's Board of
Directors (in a vote in which Founder abstains) reasonably deems to be a
competitor in the Business.

     7.  Term and Termination for Breach.  This Agreement (and all licenses
         -------------------------------
hereunder) shall be deemed to be effective beginning on the first day of the
Relationship and shall terminate on May 13, 2014 (the "Expiration Date"). A
party may terminate this Agreement in advance of the Expiration Date if the
other party has breached a material provision of this Agreement and has not
cured such breach within thirty (30) days after receiving written notice of such
breach from the nonbreaching party. If Founder terminates this Agreement
pursuant to this Section 7, Sections 1, 5 and 6 of this Agreement shall
terminate, but all other provisions of this Agreement shall survive such
termination until the Expiration Date. If the Company terminates this Agreement
pursuant to this Section 7, Section 5 of this Agreement shall terminate, but all
other provisions of this Agreement shall survive such termination until the
Expiration Date.
<PAGE>

     8.  Miscellaneous.  This Agreement sets forth the entire agreement between
         -------------
the Company and Founder relating to the subject matter herein, and supersedes
any oral, written or other communications or agreements concerning the subject
matter of this Agreement. This Agreement may be amended or waived only by a
written instrument signed by the parties. This Agreement shall be governed by
the laws of the State of California applicable to contracts entered into and
performed entirely within the State, without giving effect to principles of
conflict of law. 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.
This Agreement (a) shall survive the Relationship, (b) inures to the benefit of
successors and assigns of the Company, and (c) is binding upon Founder`s heirs
and legal representatives. Any notice given hereunder shall be in writing and
shall be sent to the address for the party on the signature page below (and as
may be changed by prior written notice to the other party) and shall deemed to
be delivered: 1) upon receipt, if by express overnight courier, personal
delivery or facsimile transmission (as evidenced by sender's confirmation
receipt), or 2) 48 hours after posting in the U.S. mail, by either certified or
registered mail.

     This Agreement is entered into as of this 14 day of May, 1999.

                                  OFFICE LEASE

  THIS LEASE is made and entered into by and between Landlord and Tenant as
of the Lease Date. Landlord and Tenant hereby agree as follows:

  1.  Definitions.

    1.1 Terms Defined. The following terms have the meanings set forth below.
Certain other terms have the meanings set forth in the Basic Lease Information
or elsewhere in this Lease.

    Alterations: Alterations, additions or other improvements to the Premises
made by or on behalf of Tenant (but not including the alterations, additions or
other improvements, if any, made by or behalf of Tenant during the initial
improvement of the Premises pursuant to and governed by the provisions of the
Work Letter attached hereto as Exhibit C).

    Base Operating Expenses and Base Real Estate Taxes: The Operating Expenses
and the Real Estate Taxes paid or incurred by Landlord in the Base Year.

    Building: The office building consisting of an 8-story tower and parking at
grade located on the Land, commonly known as 6001 Shellmound Street, Emeryville,
California.

    Marketplace: The Land, the Building, the Shopping Center, landscaping, paved
walkways, driveways and all other improvements at any time located on the Land,
and all appurtenances related thereto, commonly known as The Marketplace.

    Escalation Rent: Tenant's Percentage Share of the total dollar increase, if
any, in Operating Expenses and in Real Estate Taxes, each as paid or incurred by
Landlord in each calendar year, or part thereof, after the Base Year, over the
amount of Base Operating Expenses and Base Real Estate Taxes. If the Building or
the Marketplace is less than ninety-five percent (95%) occupied during any part
of any year (including the Base Year), Landlord shall make an appropriate
adjustment of the variable components of Operating Expenses and Real Estate
Taxes for that year, as reasonably determined by landlord using sound accounting
and management principles, to determine the amount of Operating Expenses and
Real Estate Taxes that would have been incurred during such year if the Building
and the Marketplace had been ninety-five percent (95%) occupied during the
entire year (and, if applicable, if the tenant improvements in the Building had
been fully constructed and the Land, the Marketplace, the Building, and all
tenant improvements in the Building and the Marketplace had been fully assessed
for Real Estate Tax purposes). This amount shall be considered to have been the
amount of Operating Expenses and Real Estate Taxes for that year. For purposes
hereof, "variable components" include only those component expenses that are
affected by variations in occupancy levels.

    Expansion Area:  That portion of the 8th Floor of the Building commonly
referred to as Suite 800, containing approximately 3,423 square feet of Rentable
Area and located adjacent to the Initial Premises.

    Impositions:  Taxes, assessments, charges, excises and levies, business
taxes, licenses, permits, inspection and other authorization fees, transit
development fees, assessments or charges for housing funds, service payments in
lieu of taxes and any other fees or charges of any kind at any time levied,
assessed, charged or imposed by any federal, state or local entity, (i) upon,
measured by or reasonably attributable to the cost or value of Tenant's
equipment, furniture, fixtures or other personal property located in the
Premises, or the cost or value of any alterations, additions or other
improvements to the Premises made by or on behalf of Tenant during the initial
improvement of the Premises pursuant to and governed by the Work Letter and any
subsequent Alterations; (ii) upon, or measured by, any Rent payable hereunder,
including any gross receipts tax; (iii) upon, with respect to or by reason of
the development, possession, leasing, operation, management, maintenance,
alteration, repair, use or occupancy by Tenant of the Premises, or any portion
thereof; or (iv) upon this Lease transaction, or any document to which Tenant is
a party creating or transferring any interest or estate in the Premises.
Impositions do not include Real Estate Taxes, franchise, transfer, inheritance
or capital stock taxes, or income taxes measured by the net income of Landlord
from all sources, unless any such taxes are levied or assessed against Landlord
as a substitute for, in whole or in part, any Imposition.

    Initial Premises:  That portion of the 8th floor of the Building commonly
referred to as Suite 850, containing approximately 3,855 square feet of Rentable
Area and located adjacent to the Expansion Area.

amortized over the maximum time period allowed by applicable law.

                                      11
<PAGE>

    Rentable Area: As to a floor leased entirely by Tenant, all areas within
exterior permanent Building walls measured to the inside glass surface of outer
Building walls, including restrooms, janitor, telephone and electrical closets,
mechanical areas, and columns and projections necessary to the Building, but
excluding public stairs, elevator shafts and pipe shafts. As to a floor only a
portion of which is leased by Tenant, the aggregate of (i) the Leased Area (as
defined below) of the portion of the floor occupied by Tenant, plus (ii) the
result obtained by multiplying (1) the area of the Common Area (as defined
below) on such floor by (2) a fraction whose numerator is the Leased Area of
Tenant's portion of the floor and whose denominator is the Leased Area of all
tenant space on such floor, plus (iii) in the event that Landlord must enlarge
or alter in any way, shape or fashion the Common Area to accommodate Tenant's
Leased Area, the total additional Common Area space. For purposes hereof,
"Leased Area" shall mean all floor area in a tenant space, measured to the
inside glass surface of exterior Building walls, to the center of corridors and
other permanent partitions, and to the center of partitions that separate tenant
space from adjoining tenant spaces, without deductions for columns and
projections necessary to the Building; and "Common Area" shall mean the total
area on a floor consisting of restrooms, janitor, telephone and electrical
closets, mechanical areas and public corridors providing access to tenant space
on such floor, but excluding public stairs, elevator shafts and pipe shafts.

    Shopping Center: The retail center and movie theater located on the Land.

    Tenant's Percentage Share: The percentage figure specified in the Basic
Lease Information. Landlord and Tenant acknowledge that Tenant's Percentage
Share has been obtained by dividing the Rentable Area of the Premises, as
specified in the Basic Lease Information by the total Rental Area of the
Building, and multiplying such quotient by one hundred (100). In the event
Tenant's Percentage Share is changed during a calendar year by reason of a
change in the Rentable Area of the Premises or a change in the total Rentable
Area of the Building, Tenant's Percentage Share shall thereafter mean the result
obtained by dividing the then Rentable Area of the Premises by the then total
Rentable Area of the Building and multiplying such quotient by one hundred
(100). For the purposes of determining Tenant's Percentage Share of Escalation
Rent, Tenant's Percentage Share shall be determined on the basis of the number
of days during such calendar year at each such Percentage Share.

    Term: The period from the Commencement Date to the Expiration Date.

    Wattage Allowance: The product obtained by multiplying the Rentable Area of
the Premises by 4.5 watts. "Lighting Wattage Allowance" means thirty-three
percent (33%) of the Wattage Allowance.

    1.2. Effect of Certain Defined Terms. The parties acknowledge that the
Rentable Area of the Premises and the Building have been finally determined by
the parties as part of this Lease for all purposes, including the calculation of
Tenant's Percentage Share and will not, except as otherwise provided in this
Lease, be changed.

  2. Lease of Premises. Landlord leases to Tenant and Tenant leases from
Landlord the Premises, together with the non-exclusive right to use, in common
with others, the lobbies, entrances, stairs, elevators, plazas, pedestrian
walkways, restrooms, and other public portions of the Building, all subject to
the terms, covenants and conditions set forth in this Lease. All the windows and
exterior walls of the Premises, the terraces adjacent to the Premises, if any,
and any space in the Premises used for shafts, columns, projections, stacks,
pipes, conduits, ducts, electric utilities, sinks or other Building facilities,
and the use thereof and access thereto through the Premises for the purposes of
management, operation, maintenance and repairs, are reserved to Landlord.

  3. Term; Condition and Acceptance of Premises.

    3.1 Commencement and Acceptance.

      3.1.1. Initial Premises. Except as hereinafter provided, and unless sooner

Tenant following temporary approval by the applicable building inspector
sufficient to permit Tenant to legality occupy the Initial Premises and
substantial completion of all improvements to be constructed by Landlord
pursuant to the Work Letter, except for punchlist items which do not materially

(ii) the date

                                      12
<PAGE>

Tenant enters into occupancy of the entire Initial Premises and commences the
operation of its normal business activities. No delay in delivery of the Initial
Premises for any reason whatsoever shall operate to extend the Expiration Date
or the Term. Upon the occurrence of the Commencement Date, Landlord and Tenant
shall execute a Confirmation of Lease Term in the form as set forth in Exhibit E
attached to this Lease. Tenant's occupancy of all or any portion of the Initial
Premises shall constitute Tenant's acceptance of the Initial Premises in the
condition called for by this Lease.

      3.1.2. Expansion Area. Landlord shall deliver the Expansion Area to Tenant
on the earlier of: (i) the date Landlord offers to deliver possession of the
Expansion Area to Tenant following temporary approval by the applicable building
inspector sufficient to permit Tenant to legally occupy the Expansion Area and
substantial completion of all improvements to be constructed by Landlord
pursuant to the Work Letter, except for punchlist items which do not materially
interfere with Tenant's ability to use the Expansion Area and such work as
Landlord is required to perform but cannot complete until Tenant performs
necessary portions of construction work it has elected or is required to do, or
(ii) the date Tenant enters into occupancy of the entire Expansion Area and
commences the operation of its normal business activities, but in no event later
than September 1, 1999. Tenant's occupancy of all or any portion of the
Expansion Area shall constitute Tenant's acceptance of the Expansion Area in the
condition called for by this Lease.

    3.2 Option to Extend.

      3.2.1. Exercise of Option to Extend Term. If no "Suspension Condition" (as
hereinafter defined) exists at the time of Tenant's exercise of its option to
extend the initial Term or at the commencement of the Extended Term, as the case
may be, Tenant shall have one (1) option ("Extension Option") to extend the
initial Term for one (1) additional period of five (5) years ("Extended Term").
To exercise Tenant's option with respect to the Extended Term, Tenant shall give
notice to Landlord not less than twelve (12) months prior to the expiration of
the initial Term ("Election Notice"). A "Suspension Condition" shall mean the
existence of any event or condition of material default with respect to any
obligation under this Lease where notice of default has been given by Landlord
and such default has not been cured by Tenant within the applicable notice and
cure period specified in this Lease. Tenant's exercise of the Extension Option
shall in no way result in, or constitute, a waiver by Landlord of any default by
Tenant under this Lease.

      3.2.2. Fair Market Rent. If Tenant properly and timely exercise Tenant's
option to extend pursuant to Section 3.2.1 above, such extension shall be upon
all of the same terms, covenants and conditions of this Lease; provided,
however, that the Base Rent applicable to the Premises for the Extended Term
shall be the greater of: (i) the Base Rent and Escalation Rent as of the last
month of the initial Term, or (ii) the "Fair Market Rent" for space comparable
to the Premises as of the commencement of the Extended Term. "Fair Market Rent"
shall mean the annual rental being charged for space comparable to the Premises
in a steel-frame comparable first-class office building in the
Berkeley/Emeryville area, taking into account location, parking, condition and
improvements to the space. Landlord shall not be obligated to pay any leasing
commissions or consulting fees in connection with such expansions. All other
terms and conditions of the Lease, which may be amended from time to time by the
parties in accordance with the provisions of the Lease, shall remain in full
force and effect and shall apply during the Extended Term, except that there
shall be no further option to extend, there shall be no further rent
concessions, there shall be no tenant improvement allowance and similar
provisions.

      3.2.3. Determination of Rent. Within forty-five (45) days after the date
of the Election Notice, Landlord and Tenant shall negotiate in good faith in an
attempt to determine Fair Market Rent for the Extended Term. If they are unable
to agree within said forty-five (45) day period, then the Fair Market Rent shall
be determined as provided in Section 3.2.4 below.

      3.3.4. Appraisal. If it becomes necessary to determine the Fair Market
Rent for the Premises by appraisal, the real estate appraiser(s) indicated in
this Section 3.2.4, each of whom shall be members of the Appraisal Institute and
each of whom have at least five (5) years experience appraising office space
located in the vicinity of the Premises, shall be appointed and shall act in
accordance with the following procedures:

      (i)   If the parties are unable to agree on the Fair Market Rent within
the allowed time, either party may demand an appraisal by giving written notice
to the other party, which demand to be effective must state the name, address
and qualifications of an appraiser selected by the party demanding the appraisal
("Notifying Party"). Within twenty (20) days following the Notifying Party's
appraisal demand, the other party ("Non-Notifying Party") shall either approve
the appraiser selected by the Notifying Party or select a second properly
qualified appraiser by giving written notice of the name, address and
qualification of said appraiser to the Notifying Party. If the Non-Notifying
Party fails to select an appraiser within the twenty (20) day period, the
appraiser selected by the Notifying Party shall be deemed selected by both
parties and no other appraiser shall be selected. If two (2) appraisers are
selected, they shall select a third appropriately qualified appraiser. If the
two (2) appraisers fail to

                                      13
<PAGE>

select a third qualified appraiser, the third appraiser shall be appointed by
the then presiding judge of the county where the Premises are located upon
application by either party.

      (ii)  If only one appraiser is selected, that appraiser shall notify the
parties in simple letter form of its determination of the Fair Market Rent for
the Premises within fifteen (15) days following his or her selection, which
appraisal shall be conclusively determinative and binding on the parties as the
appraised Fair Market Rent.

      (iii) If multiple appraisers are selected, the appraisers shall meet not
later than ten (10) days following the selection of the last appraiser. At such
meeting, the appraisers shall attempt to determine the Fair Market Rent for the
Premises as of the commencement date of the Extended Term by the agreement of at
least two (2) of the appraisers.

      (iv)  If two (2) or more of the appraisers agree on the Fair Market Rent
for the Premises at the initial meeting, such agreement shall be determinative
and binding upon the parties hereto and the agreeing appraisers shall forthwith
notify both Landlord and Tenant of the amount set by such agreement. If multiple
appraisers are selected and two (2) appraisers are unable to agree on the Fair
Market Rent for the Premises, each appraiser shall submit to Landlord and Tenant
his or her respective independent appraisal of the Fair Market Rent for the
Premises, in simple letter form, within twenty (20) days following appointment
of the final appraiser. The parties shall then determine the Fair Market Rent
for the Premises by averaging the appraisals; provided that any high or low
appraisal, differing from the middle appraisal by more than ten percent (10%) of
the middle appraisal, shall be disregarded in calculating the average.

      (v)  If only one (1) appraiser is selected, then each party shall pay one-
half (1/2) of the fees and expenses of that appraiser. If three (3) appraisers
are selected, each party shall bear the fees and expenses of the appraiser it
selects and one-half (1/2) of the fees and expenses of the third appraiser.

      (vi) Notwithstanding anything to the contrary contained in this Section
3.2, in no event shall the Base Rent for the Extended Term be less than the Base
Rent plus Escalation Rent payable by Tenant during the month immediately
preceding the Extended Term.

      3.2.5. Restriction on Assignment. The Extension Option shall be personal
to HealthCentral.com, a California corporation, shall not be assignable or
transferable, and shall terminate upon any assignment or sublease of all or any
portion of the Premises greater than ten percent (10%) of the Rentable Area of
the Premises.

      3.2.6. Amendment to Lease. Immediately after the Fair Market Rent has been
determined, the parties shall enter into an amendment to this Lease setting
forth the Base Rent for the Extended Term and shall also state the new
Expiration Date of the Term of the Lease.

  4. Rent.

    4.1 Obligation to Pay Base Rent. Tenant shall pay Base Rent to Landlord, in
advance, in equal monthly installments, commencing on or before the Commencement
Date, and thereafter on or before the first day of each calendar month during
the Term. If the Commencement Date and/or Expiration Date is other than the
first day of a calendar month, the installment of Base Rent for the first and/or
last fractional month of the Term shall be prorated on a daily basis. The sum of
Eight Thousand Two Hundred Eighty-Eight and 00/100 Dollars ($8,288.00)
representing an advance payment of the first monthly installment of Base Rent
for the Premises, shall be paid by Tenant to Landlord upon the execution of this
Lease by Landlord and Tenant.

    4.2  Manner of Rent Payment. All Rent shall be paid by Tenant without
notice, demand, abatement, deduction or offset, in lawful money of the United
States of America, payable to Landlord, at Landlord's Address as set forth in
the Basic Lease Information, or to such other person or at such other place as
Landlord may from time to time designate by notice to Tenant.

    4.3  Additional Rent. All Rent not characterized as Base Rent or Escalation
Rent shall constitute additional rent, and if payable to Landlord shall, unless
otherwise specified in this Lease, be due and payable thirty (30) days after
Tenant's receipt of Landlord's invoice therefor.

                                      14
<PAGE>

    4.4  Late Payment of Rent Interest. Tenant acknowledges that late payment by
Tenant of any Rent will cause Landlord to incur administrative costs not
contemplated by this Lease, the exact amount of which are extremely difficult
and impracticable to ascertain based on the facts and circumstances pertaining
as of the Lease Date. Accordingly, if any  Rent is not paid by Tenant when due,
Tenant shall pay to Landlord, with such Rent, a late charge equal to eight
percent (8%) of such Rent. Any Rent, other than late charges, due Landlord under
this Lease, if not paid when due, shall also bear interest from the date due
until paid, at the rate of ten percent (10%) per annum or, if a higher rate is
legally permissible, at the highest rate legally permitted. The parties
acknowledge that such late charge and interest represent a fair and reasonable
estimate of the administrative costs and loss of use of funds Landlord will
incur by reason of a late Rent payment by Tenant, but Landlord's acceptance of
such late charge and/or interest shall not constitute a waiver of Tenant's
default with respect to such Rent or prevent Landlord from exercising any other
rights and remedies provided under this Lease, at law or in equity.

  5. Calculation and Payments of Escalation Rent. During each full or partial
calendar year of the Term subsequent to the Base Year, Tenant shall pay to
Landlord Escalation Rent in accordance with the following procedures:

    5.1. Payment of Estimated Escalation Rent. During December of the Base Year
and December of each subsequent calendar year, or as soon thereafter as
practicable, Landlord shall give Tenant notice of its estimate of Escalation
Rent due for the next ensuing calendar year. On or before the first day of each
month during such next ensuing calendar year, Tenant shall pay to Landlord in
advance, in addition to Base Rent, one-twelfth (1/12th) of such estimated
Escalation Rent. In the event such notice is given after December 31st of any
year during the Term, (i) Tenant shall continue to pay Escalation Rent on the
basis of the prior calendar year's estimate until the month after such notice is
given, (ii) subsequent payments by Tenant shall be based of the estimate of
Escalation Rent based on the estimate set forth in Landlord's notice, Tenant
shall also pay the difference, if any, between the amount previously paid for
such calendar year and the amount which Tenant would have paid through such
month based on Landlord's noticed estimate, Landlord shall credit such excess
amount against the next monthly payments of Escalation Rent due from Tenant. If
at any time Landlord reasonably determines that the Escalation Rent for the
current calendar year will vary from Landlord's estimate by more than five
percent (5%), Landlord may, by notice to Tenant, revise its estimate for such
calendar year, and subsequent payments by Tenant for such calendar year shall be
based upon such revised estimate.

    5.2. Escalation Rent Statement and Adjustment. Within one hundred twenty
(120) days after the close of each calendar year, or as soon thereafter as
practicable, Landlord shall deliver to Tenant a statement of the actual
Escalation Rent for such calendar year, accompanied by a statement prepared by
Landlord showing in reasonable detail the Operating Expenses and the Real Estate
Taxes comprising the actual Escalation Rent. If Landlord's statement shows that
Tenant owes an amount less than the payments previously made by Tenant for such
calendar year, Landlord shall credit the difference first against any sums then
owed by Tenant to Landlord and then against the next payment or payments of Rent
due Landlord, except that if a credit amount is due Tenant after termination of
this Lease, Landlord shall pay to Tenant any excess remaining after Landlord
credits such amount against any sums owed by Tenant to Landlord. If Landlord's
statement shows that Tenant owes an amount more than the payments previously
made by Tenant for such calendar year, Tenant shall pay the difference to
Landlord within fifteen (15) days after delivery of the statement.

    5.3. Proration for Partial Year. If this Lease terminates other than on the
last day of a calendar year (other than due to Tenant's default), the amount of
Escalation Rent for such fractional calendar year shall be prorated on a daily
basis. Upon such termination, Landlord may, at its option, calculate the
adjustment in Escalation Rent prior to the time specified in Section 5.2 above.
Tenant's obligation to pay Escalation Rent, as set forth in Section 5.2, above,
shall survive the expiration or termination of this Lease. If Tenant has
overpaid Escalation Rent applicable to any period after the expiration of the
Term, Landlord shall refund the overpayment to Tenant.

  6. Impositions Payable by Tenant. Tenant shall pay all Impositions prior to
delinquency. If billed directly to Tenant, Tenant shall pay such Impositions and
concurrently deliver to Landlord evidence of such payments. If any Impositions
are billed to Landlord or included in bills to Landlord for Real Estate Taxes or
other charges, then Tenant shall pay to Landlord all such amounts within thirty
(30) days after delivery of Landlord's invoice therefor. If applicable law
prohibits Tenant from reimbursing Landlord for an Imposition, but Landlord may
lawfully increase the Base Rent to account for Landlord's payment of such
Imposition, the Base Rent payable to Landlord shall be increased to net to
Landlord the same return without reimbursement of such Imposition as would have
been received by Landlord with reimbursement of such Imposition. Tenant's
obligation to pay Impositions which have accrued and remain unpaid upon the
expiration or earlier termination of this Lease shall survive the expiration or
earlier termination of this Lease.

  7. Use of Premises.

                                      15
<PAGE>

          7.1. Permitted Use. The Premises shall be used solely for the
Permitted Use and for no other use of purpose.

          7.2. No Violation of Legal and Insurance Requirements. Tenant shall
not do or permit to be done, or bring or keep or permit to be brought or kept,
in or about the Premises, or any other portion of the Marketplace, anything
which (i) is prohibited by or will in any way conflict with any law, ordinance,
rule or regulation; (ii) would invalidate or be in conflict with the provisions
of any insurance policy carried by Landlord or Tenant on any portion of the
Marketplace or Premises, or any property therein, or (iii) would cause a
cancellation of any such insurance, increase the existing rate of or affect any
such Landlord's insurance, or subject Landlord to any liability or
responsibility for injury to any person or property. If Tenant does or permits
anything to be done which increases the cost of any of Landlord's insurance, or
which results in the need, in Landlord's reasonable judgment, for additional
insurance by Landlord or Tenant with respect to any portion of the Marketplace
or Premises, then Tenant shall reimburse Landlord, upon demand, for any such
additional costs or the costs of such additional insurance, and/or procure such
additional insurance at Tenant's sole cost and expense. Exercise by Landlord of
such right to require reimbursement of additional costs (including the costs of
procuring of additional insurance) shall not limit or preclude Landlord from
prohibiting Tenant's impermissible use of the Premises or from invoking any
other right or remedy available to Landlord under this Lease.

          7.3. Compliance with Legal Insurance and Life Safety Requirements.
Except as provided in clauses (i) through (iii) below, Tenant, at its cost and
expense, shall promptly comply with all laws, ordinances, rules, regulations,
orders and other governmental requirements, the requirements of any board of
fire underwriters or other similar body, any directive or occupancy certificate
issued pursuant to any law by any public officer or officers, the provisions of
all recorded documents affecting any portions of the Marketplace and all life
safety programs, procedures and rules implemented or promulgated by Landlord
("Laws"). Tenant shall not, however, be required to comply with Laws requiring
Tenant to make structural changes to the Premises unless necessitated, in whole
or in part, by (i) Tenant's use or occupancy of, or business conducted in, the
Premises, (ii) any acts or omissions of Tenant, its employees, agents,
contractors, invitees or licensees, or (iii) Alterations (including any
alterations, additions or other improvements to the Premises made by or on
behalf of Tenant during the initial improvement of the premises pursuant to the
Work Letter).

          7.4. No Nuisance. Tenant shall not (i) do or permit anything to be
done in or about the Premises, or any other portion of the Marketplace, which
would injure or annoy, or obstruct or interfere with the rights of, Landlord or
other occupants of the Marketplace, or others lawfully in or about the
Marketplace; (ii) use or allow the Premises to be used in any manner
inappropriate for a Class A office building, or for any improper or
objectionable purposes; or (iii) cause, maintain or permit any nuisance or waste
in, on or about the Premises, or any other portion of the Marketplace.

          7.5. Hazardous Substances. The term "hazardous substances" as used in
the Lease, is defined as follows:

     Any element, compound, mixture, solution, particle or substance, which
     presents danger or potential danger of damage or injury to health, welfare
     or to the environment including, but not limited to: (i) those substances
     which are inherently or potentially radioactive, explosive, ignitable,
     corrosive, reactive, carcinogenic or toxic and (ii) those substances which
     have been recognized as dangerous or potentially dangerous to health,
     welfare or to the environment by any federal, municipal, state, county or
     other government or quasi-governmental authority and/or any department or
     agency thereof.

     Tenant represents and warrants to Landlord and agrees that at all times
during the term of this Lease and any extensions or renewals thereof, Tenant
shall:

          (i)  promptly comply at Tenant's sole cost and expense, with all laws,
     orders, rules, regulations, certificates of occupancy, or other
     requirements, as the same now exist or may hereafter be enacted, amended or
     promulgated, of any federal, municipal, state, county or other governmental
     or quasi-governmental authorities and/or any department or agency thereof
     relating to the manufacturing, processing, distributing, using, producing,
     treating, storing (above or below ground level), disposing or allowing to
     be present (the "Environmental Activity") of hazardous substances in or
     about the Premises (each, a "Law", and all of them, "Laws").

          (ii) indemnify and hold Landlord, its agents and employees, harmless
     from any and all demands, claims, causes of action, penalties, liabilities,
     judgments, damages (including consequential damages) and expenses
     including, without limitation, court costs and reasonable attorneys' fees
     incurred by Landlord as a result of (a) Tenant's failure or delay in
     properly complying with any Law, or (b) any adverse effect which results
     from the Environmental Activity, whether Tenant or Tenant's subtenants or
     any
<PAGE>

     of their respective agents, employees, contractors or invitees, with or
     without Tenant's consent has caused, either intentionally or
     unintentionally, such Environmental Activity. If any action or proceeding
     is brought against Landlord, its agents or employees by reason of any such
     claim, Tenant, upon notice from Landlord, will defend such claim at
     Tenant's expense with counsel reasonably satisfactory to Landlord. This
     indemnity obligation by Tenant of Landlord will survive the expiration or
     earlier termination of this Lease.

          (iii) promptly disclose to Landlord by delivering, in the manner
     prescribed for delivery of notice in this Lease, a copy of any forms,
     submissions, notices, reports, or other written documentation (each, a
     "Communication") relating to any Environmental Activity, whether any such
     Communication is delivered to Tenant or any of its subtenants or is
     requested of Tenant or any of its subtenants by any federal, municipal,
     state, county or other government or quasi-governmental authority and/or
     any department or agency thereof.

          (iv)  in the event there is a release of any hazardous substance as a
     result of or in connection with any Environmental Activity by Tenant or any
     of Tenant's subtenants or any of their respective agents, employees,
     contractors or invitees, which must be remediated under any Law, Landlord
     shall perform the necessary remediation; and Tenant shall reimburse
     Landlord for all costs thereby incurred within fifteen (15) days after
     delivery of a written demand therefor from Landlord (which shall be
     accompanied by reasonable substantiation of such costs). In the
     alternative, Landlord shall have the right to require Tenant, at its sole
     cost and expense, to perform the necessary remediation in accordance with a
     detailed plan of remediation which shall have been approved in advance in
     writing by Landlord. Landlord shall give notice to Tenant within thirty
     (30) days after Landlord receives notice or obtains knowledge of the
     required remediation. The rights and obligations of Landlord and Tenant set
     forth in this subparagraph (iv) shall survive the expiration or earlier
     termination of this Lease.

          (v)   notwithstanding any other provisions of this Lease, allow
     Landlord, any authorized representative of Landlord, access and the right
     to enter and inspect the Premises for Environmental Activity, at any time
     deemed reasonable by Landlord, without prior notice to Tenant.

     Compliance by Tenant with any provision of this Section 7.5 shall not be
deemed a waiver of any other provision of this Lease. Without limiting the
foregoing, Landlord's consent to any Environmental Activity shall not relieve
Tenant of its indemnity obligations under the terms hereof.

          7.6. Special Provisions Relating to The Americans With Disabilities
Act of 1990. 7.6.1. Allocation of Responsibility to Landlord. As between
Landlord and Tenant, Landlord shall be responsible that the public entrances,
stairways, corridors, elevators and elevator lobbies and other public areas in
the Building and in the Marketplace comply with the requirements of Title III of
the Americans with Disabilities Act of 1990 (42 U.S.C. 12181, et seq., The
Provisions Governing Public Accommodations and Services Operated by Private
Entities), and all regulations promulgated thereunder, and all amendments,
revisions or modifications thereto now or hereafter adopted or in effect in
connection therewith (hereinafter collectively referred to as the "ADA"), and to
take such actions and make such alterations and improvements as are necessary
for such compliance. All costs incurred by Landlord in discharging its
responsibilities under this Section 7.6] shall be included in Operating Expenses
as provided in Section 1.1.

               7.6.2. Allocation of Responsibility to Tenant. As between
Landlord and Tenant, Tenant, at its sole cost and expense, shall be responsible
that the Premises, all Alterations to the Premises, Tenant's use and occupancy
of the Premises, and Tenant's performance of its obligations under this Lease,
comply with the requirements of the ADA, and to take such actions and make such
Alterations as are necessary for such compliance; provided, however, that Tenant
shall not make any such Alterations except upon Landlord's prior written consent
pursuant to the terms and conditions of this Lease. Tenant shall protect,
defend, indemnify and hold Landlord harmless from and against any claim, demand,
cause of action, obligation, liability, loss, cost or expense (including
reasonable attorneys' fees) which may be asserted against or incurred by
Landlord as a result of Tenant's failure in any respect to comply with its
obligations set forth hereinabove in this Section 7.6.2. Tenant's indemnity
obligations set forth in the immediately preceding sentence shall survive the
expiration or earlier termination of this Lease.

               7.6.3. General. Notwithstanding anything in this Lease to the
contrary, no act or omission of Landlord, including any approval, consent or
acceptance by Landlord or Landlord's agents, employees or other representatives,
shall be deemed an agreement, acknowledgment, warranty, or other representation
by Landlord that Tenant has complied with the ADA or that any action, alteration
or improvement by Tenant complies or will comply with the ADA or constituents a
waiver by Landlord of Tenant's obligations to comply with the ADA under this
Lease or otherwise. Any failure of Landlord to comply with the obligations of
the ADA shall not
<PAGE>

relieve Tenant from any obligations under this Lease or constitute or be
construed as a constructive or other eviction of Tenant or disturbance of
Tenant's use and possession of the Premises.

     8. Building Services.

          8.1. Maintenance of Marketplace. Landlord shall maintain the
Marketplace (other than the Premises and the premises of other tenants of the
Marketplace) in good order and condition, except for ordinary wear and tear,
damage by casualty or condemnation, or damage occasioned by the act or omission
of Tenant or Tenant's employees, agents, contractors, licensees or invitees,
which damage shall be repaired by Landlord at Tenant's expense. Landlord's
maintenance of, and provision of services to, the Building shall be performed in
a manner consistent with that of comparable Class A office buildings in the
Emeryville/Oakland, California area. Landlord shall have the right in connection
with its maintenance of the Marketplace hereunder (i) to change the arrangement
and/or location of any amenity, installation or improvement in the public
entrances, stairways, corridors, elevators and elevator lobbies, and other
public areas in the Building, or other public areas of the Marketplace, and (ii)
to utilize portions of the public areas in the Building and the Marketplace from
time to time for entertainment, displays, product shows, leasing of kiosks or
such other uses that in Landlord's sole judgment tend to attract the public, so
long as such uses do not materially interfere with or impair Tenant's access to
or use or occupancy of the Premises. Landlord shall not be in default under this
Lease or liable for any damages directly or indirectly resulting from or
incidental to, nor shall the rental reserved in this Lease be abated by reason
of, Landlord's failure to make any repair or to perform any maintenance required
to be made or performed by Landlord under this Section 8.1, unless such failure
shall persist for an unreasonable time after written notice of the need for such
repair or maintenance is given to Landlord by Tenant.

          8.2. Building Standard Services. Landlord shall cause to be furnished
to Tenant: (i) tepid and cold water to those points of supply and in volumes
provided for general use of tenants in the Building; (ii) electricity up to the
Wattage Allowance for lighting and the operation of electrically powered office
equipment; (iii) heat, ventilation and air conditioning to the extent reasonably
required for the comfortable occupancy by Tenant of the Premises during the
period from 8:00 a.m. to 6:00 p.m. on weekdays (except Building holidays
determined by Landlord), or such shorter period as may be prescribed by any
applicable policies, regulations or guidelines adopted by any federal, state or
local governmental or quasi-governmental entities or utility suppliers; (iv)
passenger elevator service; (v) freight elevator service subject to then
applicable Building standard procedures and scheduling; (vi) lighting
replacement for Building standard lights; (vii) restroom supplies; (viii) window
washing as determined by Landlord; (ix) janitor service on a five (5) day per
week basis (excluding Building holidays), except for portions of the Premises
used for preparing or consuming food or beverages; and (x) security if and to
the extent deemed appropriate by Landlord for the Marketplace (but not
individually for Tenant or the Premises), except that Landlord shall not be
liable in any manner for acts of others, criminal or otherwise, or for any
direct, consequential or other loss, damage, death or injury related to any
interruption, discontinuance, malfunction, circumvention or failure of such
security service. Landlord may establish in the Premises or other portions of
the Marketplace such measures as are required by laws, ordinances, rules or
regulations or as it deems necessary or appropriate to conserve energy,
including automatic switching of lights and/or more efficient forms of lighting.

          8.3. Interruption or Unavailability of Services. Rent shall not abate,
no constructive or other eviction shall be construed to have occurred, Tenant
shall not be relieved from any of its obligations under this Lease, and Landlord
shall not be in default hereunder or liable for any damages directly or
indirectly resulting from, the failure of Landlord to furnish, or delay in
furnishing, any maintenance or services under this Article 8 as a result of
repairs, alterations, improvements or any circumstances beyond Landlord's
reasonable control. Landlord shall use reasonable diligence to remedy any
failure or interruption in the furnishing of such maintenance or services.

          8.4. Tenant's Use of Excess Electricity and Water. Tenant shall not,
without Landlord's prior consent, given or withheld in Landlord's sole
discretion, (i) install in the Premises (A) lighting, the aggregate average
daily power usage of which exceeds the Lighting Wattage Allowance, or lighting
and equipment, the aggregate average daily power usage of which exceeds the
Wattage Allowance, or which requires a voltage other than 110 volts single-
phase, (B) heat generating equipment or lighting other than lights deemed
standard for the Building, or (C) supplementary air conditioning facilities, or
(ii) permit occupancy levels in excess of one person per one hundred eighty
(180) square feet of Rentable Area. If, pursuant to this Section 8.4, heat-
generating equipment or lighting other than Building standard lights are
installed or used in the Premises, or occupancy levels are greater than set
forth above, or if the Premises or fixtures therein are reconfigured by
Alterations, and such equipment, lighting, occupancy levels or Premises
reconfiguration affects the temperature otherwise maintained by the Building air
conditioning system, or if equipment is installed in the Premises which requires
a separate temperature-controlled room, Landlord may, at Landlord's election
after notice to Tenant or upon Tenant's request, install supplementary air
conditioning facilities in the Premises, or otherwise modify the ventilating and
air
<PAGE>

conditioning serving the Premises, in order to maintain the temperature
otherwise maintained by the Building air conditioning system or to serve such
separate temperature-controlled room. Tenant shall pay the cost of any
transformers, additional risers, panel boards and other facilities, if, when and
to the extent required to furnish power for, and all maintenance and service
costs of, any supplementary air conditioning facilities or modified ventilating
and air conditioning, or for lighting and/or equipment the power usage of which
exceeds the standards set forth in this Section 8.4. The capital, maintenance
and service costs of such facilities and modifications shall be paid by Tenant
as Rent. Landlord, at its election and at Tenant's expense, may also install and
maintain an electric current meter or water meter (together with all necessary
wiring and related equipment) at the Premises to measure the power and/or water
usage of such lighting, equipment or ventilation and air conditioning equipment,
or may otherwise cause such usage to be measured by reasonable methods.

          8.5. Provision of Additional Services. If Tenant desires services in
additional amounts or at different times than set forth in Section 8.2 above, or
any other services that are not provided for in this Lease, Tenant shall make a
request for such services to Landlord with such advance notice as Landlord may
reasonably require. If Landlord provides such services to Tenant, Tenant shall
pay Landlord's charges for such services within thirty (30) days after Tenant's
receipt of Landlord's invoice, except that (i) electricity shall be charged at
Landlord's actual cost, (ii) the initial charge for additional HVAC service
provided by the Building central system shall be at the rate of $28.00 per hour
per full floor (the "HVAC Additional Rate"); (iii) the initial charge for
additional lighting service provided by the Building central system shall be at
the rate of $4.25 per hour per full floor (the "Lighting Additional Rate");
provided, however, that Landlord shall have the right, from time to time during
the Term, to increase the HVAC Additional Rate and the Lighting Additional Rate
to reflect increases in Landlord's actual cost for providing additional HVAC
service and lighting service. Notwithstanding the foregoing, if at any time the
holder of the beneficial interest of deed of trust encumbering the Marketplace,
Teachers Insurance and annuity Association ("Teachers), becomes the Landlord
under this Lease, then during the time that Teachers is the Landlord under this
Lease the amounts charged by Landlord under items (i), (ii) and (iii) of this
Section 8.5 shall be charged at Landlord's actual cost.

     9.  Maintenance of Premises. Tenant shall, at all times during the Term, at
Tenant's cost and expense, keep the Premises in good condition and repair,
except for ordinary wear and tear and damage by casualty or condemnation. Except
as may be specifically set forth in this Lease (including the Work Letter
attached to this Lease as Exhibit C), Landlord has no obligation to alter,
remodel, improve, repair, decorate or paint the Premises, or any part thereof,
or any obligation respecting the condition, maintenance and repair of the
Premises or any other portion of the Marketplace. Tenant hereby waives all
rights, including those provided in California Civil Code Section 1941 or any
successor statute, to make repairs which are Landlord's obligation under this
Lease at the expense of Landlord or to receive any setoff or abatement of Rent
or in lieu thereof to vacate the premises or terminate this Lease.

     10. Alterations to Premises.

         10.1. Landlord Consent; Procedure. Tenant shall not make or permit to
be made any structural Alterations without Landlord's prior consent, which
consent may be granted or withheld in Landlord's sole discretion, not make or
permit to be made any non-structural Alterations without Landlord's prior
consent, which consent shall not be unreasonably withheld. Any Alterations to
which Landlord has consented shall be made in accordance with procedures as then
established by Landlord and the provisions of this Article 10.

         10.2. General Requirements. All Alterations shall be made at Tenant's
cost and expense. Tenant shall be solely responsible for compliance with
applicable laws, ordinances, rules and regulations in connection with all
Alterations. Tenant shall be responsible for the cost of any additional
alterations required by applicable laws, ordinances, rules and regulations to be
made by Landlord to any portion of the Marketplace as a result of Alterations.
Tenant shall promptly commence or cause the commencement of construction of all
Alterations and complete or cause completion of the same with due diligence as
soon as possible after commencement in order to cause the least disruption to
Marketplace operations and occupants and to continue Tenant's business in the
Premises. In connection with installing or removing Alterations, Tenant shall
pay Landlord's then standard charges for review and approval of Tenant's plans,
specifications and working drawings, and administration by Landlord (or its
agent) of the construction, installation or removal of Alterations, and
restoration of the Premises to their previous condition.

         10.3. Removal of Alterations. If required by Landlord at the time
Landlord provides consent to an Alteration and Landlord so notifies Tenant of
such requirement at the time of Landlord's consent, Tenant shall, prior to the
expiration of the Term or termination of this Lease, remove such Alteration at
Tenant's cost and expense and restore the Premises to the condition existing
prior to the installation of such Alteration. If Tenant fails so to do, then
Landlord may remove such Alteration and perform such restoration and

<PAGE>

Tenant shall reimburse Landlord for Landlord's cost and expense incurred to
perform such removal and restoration (which obligation of Tenant shall survive
the expiration or earlier termination of this Lease). Tenant shall repair at its
cost and expense all damage to the Premises or Marketplace caused by the removal
of such Alteration. Subject to the foregoing provisions regarding removal, all
Alterations (including any above Building standard improvements to the Premises)
shall be Landlord's property and from and after the expiration or earlier
termination of this Lease shall remain on the Premises without compensation to
Tenant.

     11. Liens. Tenant shall keep the Premises and the Marketplace free from any
liens arising out of any work performed or obligations incurred by or for, or
materials furnished to, Tenant pursuant to this Lease or otherwise. Landlord
shall have the right to post and keep posted on the Premises any notices
required by law or which Landlord may deem to be proper for the protection of
Landlord, the Premises and the Marketplace from such liens and to take any other
action at the expense of Tenant that Landlord deems necessary or appropriate to
prevent, remove or discharge such liens. Tenant shall protect, defend, indemnify
and hold Landlord harmless from and against any claim, demand, cause of action,
obligation, liability, loss, cost or expense (including reasonable attorney's
fees) which may be asserted against or incurred by Landlord as a result of
Tenant's failure to comply with the foregoing obligation (which indemnity
obligation shall survive the expiration or earlier termination of this Lease).

     12. Damage or Destruction.

          12.1. Obligation to Repair. Except as otherwise provided in this
Article 12, if the Premises, or any other portion of the Marketplace necessary
for Tenant's use and occupancy of the Premises, are damaged or destroyed by fire
or other casualty, Landlord shall, within thirty (30) days after such event,
notify Tenant of the estimated time, in Landlord's reasonable judgment, required
to repair such damage or destruction. If Landlord's estimate of time is less
than one hundred twenty (120) days after the date of damage or destruction, then
(i) Landlord shall proceed with all due diligence to repair the Premises, and/or
the portion of the Marketplace necessary for Tenant's use and occupancy of the
Premises, to substantially the condition existing immediately before such damage
or destruction, as permitted by and subject to then applicable laws, ordinances,
rules and regulations; (ii) this Lease shall remain in full force and effect;
and (iii) to the extent such damage or destruction did not result from the
negligence or willful act or omission of Tenant or Tenant's subtenants or any of
their respective employees, agents, contractors, invitees or licensees, Base
Rent shall abate for such part of the Premises rendered unusable by Tenant in
the conduct of its business during the time such part is so unusable, in the
proportion that the Rentable Area contained in the unusable part of the Premises
bears to the total Rentable Area of the Premises.

          12.2. Landlord's Election. If Landlord determines that the necessary
repairs cannot be completed within one hundred twenty (120) days after the date
of damage or destruction, or if such damage or destruction arises from causes
not covered by Landlord's insurance policy then in force, Landlord may elect, in
its notice to Tenant pursuant to Section 12.1, to (i) terminate this Lease or
(ii) repair the Premises or the portion of the Marketplace necessary for
Tenant's use and occupancy of the Premises pursuant to the applicable provisions
of Section 12.1 above. If Landlord terminates this Lease, then this Lease shall
terminate as of the date of occurrence of the damage or destruction.

          12.3. Cost of Repairs. Landlord shall pay the cost for repair of the
Marketplace and all improvements in the Premises, other than any Alterations.
Tenant shall pay the costs to repair all Alterations (but Landlord shall make
available to Tenant for such purpose any insurance proceeds received by Landlord
for such purpose under Landlord's insurance policy then in force). Tenant shall
also replace or repair, at Tenant's cost and expense, Tenant's movable
furniture, equipment, trade fixtures and other personal property in the Premises
which Tenant shall be responsible for insuring during the Term of this Lease.

          12.4. Damage at End of Term. Notwithstanding anything to the contrary
contained in this Article 12, if the Premises, or any other portion thereof or
of the Marketplace, are damaged or destroyed by fire or other casualty within
the last eighteen (18) months of the Term, then either Landlord or Tenant shall
have the right to terminate this Lease by notice to the other given within
ninety (90) days after the date of such event. Such termination shall be
effective on the date specified in Landlord's or Tenant's notice to terminate,
but in no event later than the end of such 90-day period.

          12.5. Waiver of Statutes. The respective rights and obligations of
Landlord and Tenant in the event of any damage to or destruction of the
Premises, or any other portion of the Marketplace, are governed exclusively by
this Lease. Accordingly, Tenant hereby waives the provisions of any law to the
contrary, including California Civil Code Sections 1932(2) and 1993(4) providing
for the termination of a lease upon destruction of the leased property.

     13. Eminent Domain.
<PAGE>

          13.1. Effect of Taking. Except as otherwise provided in this Article
13, if all or any part of the Premises is taken as a result of the exercise of
the power of eminent domain or condemned for any public or quasi-public purpose,
or if any transfer is made in avoidance of such exercise of the power of eminent
domain (collectively, "taken" or a "taking"), this Lease shall terminate as to
the part of the Premises so taken as of the effective date of such taking. On a
taking of a portion of the Premises, Landlord and Tenant shall each have the
right to terminate this Lease by notice to the other given within thirty (30)
days after the effective date of such taking, if the portion of the Premises
taken is of such extent and nature so as to materially impair Tenant's business
use of the balance of the Premises, as reasonably determined by the party giving
such notice. Such termination shall be operative as of the effective date of the
taking. Landlord may also terminate this Lease on a taking of any other portion
of the Marketplace if Landlord reasonably determines that such taking is of such
extent and nature as to render the operation of the remaining Marketplace
economically infeasible or to require a substantial alteration or reconstruction
of such remaining portion. Landlord shall elect such termination by notice to
Tenant given within thirty (30) days after the effective date of such taking,
and such termination shall be operative as of the effective date of such taking
of the Premises which does not result in a termination of this Lease, the Base
Rent shall thereafter be reduced as of the effective date of such taking in the
proportion that the Rentable area of the Premises so taken bears to the total
Rentable Area of the Premises.

          13.2. Condemnation Proceeds. Except as hereinafter provided, in the
event of any taking, Landlord shall have the right to all compensation, damages,
income, rent or awards made with respect thereto (collectively an "award"),
including any award for the value of the leasehold estate created by this Lease.
No award to Landlord shall be apportioned and, subject to Tenant's rights
hereinafter specified, Tenant hereby assigns to Landlord any right of Tenant in
any award made for any taking. So long as such claim will not reduce any award
otherwise payable to Landlord under this Section 13.2, Tenant may seek to
recover, at its cost and expense, as a separate claim, any damages or awards
payable on a taking of the Premises to compensate for the unamortized cost paid
by Tenant for the alterations, additions or improvements, if any, made by or on
behalf of Tenant during the initial improvement of the Premises pursuant to the
Work Letter and for any Alterations, or for Tenant's personal property taken, or
for interference with or interruption of Tenant's business (including goodwill),
or for Tenant's removal and relocation expenses.

          13.3. Restoration of Premises. On a taking of the Premises which does
not result in a termination of this Lease, Landlord and Tenant shall restore the
Premises as nearly as possible to the condition they were in prior to the taking
in accordance with the applicable provisions and allocation of responsibility
for repair and restoration of the Premises on damage or destruction pursuant to
Article 12 above, and both parties shall use any awards received by such party
attributable to the Premises for such purpose.

          13.4. Taking at End of Term. Notwithstanding anything to the contrary
contained in this Article 13, if the Premises, or any other portion thereof or
of the Marketplace, are taken within the last three hundred sixty-five (365)
days of the Term, then Landlord shall have the right, in its sole discretion, to
terminate this Lease by notice to Tenant given within ninety (90) days after the
date of such taking. Such termination shall be effective on the date specified
in Landlord's notice to Tenant, but in no event later than the end of such 90-
day period.

          13.5. Tenant Waiver. The rights and obligations of Landlord and Tenant
on any taking of the premises or any other portion of the Marketplace are
governed exclusively by this Lease. Accordingly, Tenant hereby waives the
provisions of any law to the contrary, including California Code of Civil
Procedure Sections 1265.120 and 1265.130, or any similar successor statute.

     14. Insurance.

          14.1. Liability Insurance. Landlord, with respect to the Marketplace,
and Tenant, at its cost and expense with respect to the Premises, shall each
maintain or cause to be maintained, from the Lease Date and throughout the Term,
a policy or policies of Commercial General Liability insurance with limits of
liability not less than Two Million Dollars ($2,000,000.00) per occurrence and
in the aggregate. Each policy shall contain coverage for blanket contractual
liability, personal injury liability, and premises operations, coverage deleting
liquor liability exclusions and, as to Tenant's insurance, fire legal liability.
Landlord shall have the right to approve the deductible under each policy of
Tenant's liability insurance, such approval not to be unreasonably withheld.

          14.2. Form of Policies. All insurance required by this Article 14
shall be issued on an occurrence basis by solvent companies qualified to do
business in the State of California. Any insurance required under this Article
14 may be maintained under a "blanket policy", insuring other parties and other
locations, so long as the amount and coverage required to be provided hereunder
is not thereby diminished. Notwithstanding the foregoing, Landlord shall have
the right to self-insure against any of the risks required to be
<PAGE>

insured against under this Article 14. Tenant shall provide Landlord a copy of
each policy of insurance or a certificate thereof certifying that the policies
contain the provisions required hereunder. Tenant shall deliver such policies or
certificates to Landlord within (30) days after the Lease Date, but in no event
less than ten (10) business days prior to the Commencement Date or such earlier
date as Tenant or Tenant's contractors, agents, licensees, invitees or employees
first enter the Premises and, upon renewal, not less than thirty (30) days prior
to the expiration of such coverage. All evidence of insurance provided to
Landlord shall provide (i) that Landlord, Landlord's managing agent and any
other person requested by Landlord who has an insurable interest, is designated
as an additional insured without limitation as to coverage afforded under such
policy; (ii) for severability of interests or that the acts or omissions of one
of the insureds or additional insureds shall not reduce or affect coverage
available to any other insured or additional insured; (iii) that the insurer
agrees not to cancel or alter the policy without at least thirty (30) days prior
written notice to all additional insureds; (iv) that the aggregate liability
applies solely to the Premises and the remainder of the Marketplace; and (v)
that Tenant's insurance is primary and noncontributing with any insurance
carried by Landlord.

          14.3. Workers' Compensation Insurance. Tenant, at its sole cost and
expense, shall maintain Workers' Compensation insurance as required by law and
employer's liability insurance in an amount of not less than Five Hundred
Thousand Dollars ($500,000).

          14.4. Additional Tenant Insurance. Tenant, at its sole cost and
expense, shall maintain such other insurance as Landlord may reasonably require
from time to time, but in no event may Landlord require any other insurance
which is (i) not then being required of comparable tenants leasing comparable
amounts of space in comparable buildings in the vicinity of the Building or (ii)
not then available at commercially reasonable rates.

     15.  Waiver of Subrogation Rights. Notwithstanding anything to the contrary
contained in this Lease, Landlord and Tenant, for themselves and their
respective insurers, agree to and do hereby release each other of and from any
and all claims, demands, actions and causes of action that each may have or
claim to have against the other for loss or damage to property, both real and
personal, notwithstanding that any such loss or damage may be due to or result
from the negligence of either of the parties hereto or their respective
employees or agents. Each party shall, to the extent such insurance endorsement
is lawfully available at commercially reasonable rates, obtain or cause to be
obtained, for the benefit of the other party, a waiver of any right of
subrogation which the insurer of such party may acquire against the other party
by virtue of the payment of any such loss covered by such insurance.

     16.  Tenant's Waiver of Liability and Indemnification

          16.1. Waiver and Release. Except to the extent due to the gross
negligence of willful misconduct of Landlord, Landlord shall not be liable to
Tenant or Tenant's employees, agents, contractors, licensees or invitees for,
and Tenant waives and releases Landlord and Landlord's managing agent from, all
claims for loss or damage to any property or injury, illness or death of any
person in, upon or about the Premises and/or any other portion of the
Marketplace (including claims caused in whole or in part by the act, omission,
or neglect of other tenants, contractors, licensees, invitees or other occupants
of the Marketplace or their agents or employees). The waiver and release
contained in this Section 16.1 extends to the officers, directors, shareholders,
partners, employees, agents and representatives of Landlord.

          16.2. Indemnification of Landlord. From and after the date Tenant
enters into occupancy of the Premises, Tenant shall indemnify, defend, protect
and hold Landlord harmless of and from any and all loss, liens, liability,
claims, causes of action, damages, injury, cost or expense arising out of or in
connection with (i) the making of any alterations, additions or other
improvements made by or on behalf of Tenant during the initial improvement of
the Premises pursuant to the Work Letter or any Alterations, or (ii) injury to
or death of persons or damage to property occurring or resulting directly or
indirectly from: (A) the use of occupancy of, or the conduct of business in, the
Premises by Tenant or its subtenants or any of their respective officers,
directors, employees, agents, contractors, invitees or licensees; (B) any other
occurrence or condition in or on the Premises; and (C) acts, neglect or
omissions of Tenant, or its subtenants or any of their respective officers,
directors, employees, agents, contractors, invitees or licensees, in or about
any portion of the Marketplace. Tenant's indemnity obligation includes
reasonable attorneys' fees and costs, investigation costs and all other
reasonable costs and expenses incurred by Landlord. If Landlord disapproves the
legal counsel proposed by Tenant for the defense of any claim indemnified
against hereunder, Landlord shall have the right to appoint its own legal
counsel, the reasonable fees, costs and expenses of which shall be included as
part of Tenant's indemnity obligation hereunder. The indemnification contained
in this Section 16.2 shall extend to the officers, directors, shareholders,
partners, employees, agents and representatives of Landlord.

          16.3. Indemnification of Tenant. Landlord shall indemnify, defend,
protect and hold Tenant harmless of and from any and all loss, liens, liability,
causes of action, damage, injury, cost or expense arising out of or in
connection with (i) any breach or default by
<PAGE>

Landlord in the performance of any of its obligations under this Lease, or (ii)
any loss or damage to property or injury to person occurring in the public
entrances, stairways, corridors, elevators and elevator lobbies, and other
public areas in the Building or other public areas in the Marketplace (except
for such loss, damage or injury for which Tenant is obligated to indemnify
Landlord under Section 16.2).

     17. Assignment and Subletting.

          17.1. Compliance Required. Tenant shall not, directly or indirectly,
voluntary or by operation of law, sell, assign or otherwise transfer this Lease,
or any interest herein (collectively, "assign" or "assignment"), or sublet the
Premises, or any part thereof, or permit the occupancy of the Premises by any
person other than Tenant (collectively, "sublease" or "subletting", the assignee
or sublessee under an assignment or sublease being referred to as a
"transferee"), without Landlord's prior consent given or withheld in accordance
with the express standards and conditions of this Article 17 and compliance with
the other provisions of this Article 17. Any assignment or subletting made in
violation of this Article 17 shall be void. As used herein, an "assignment"
includes any sale or other transfer (such as by consolidation, merger or
reorganization) of a majority of the voting stock of Tenant, if Tenant is a
corporation, or any sale or other transfer of a majority of the beneficial
interest in Tenant, if Tenant is any other form of entity; provided, however,
that the sale of a majority of the voting stock of HealthCentral.com pursuant to
an initial public offering of such stock shall not constitute an assignment
under this Article 17 and the sale of less than fifty percent (50%) of the
voting stock of HealthCentral.com pursuant to a private placement of such stock
shall not constitute an assignment under this Article 17. Tenant acknowledges
and agrees that the limitations on Tenant's right to sublet or assign which are
set forth in this Article 17 are reasonable and, in particular, that the express
standards and conditions upon Tenant's right to assign or sublet which are set
forth in this Article 17 are reasonable as of the Lease Date.

          17.2. Request by Tenant; Landlord Response. If Tenant desires to
effect an assignment or sublease, Tenant shall submit to Landlord a request for
consent together with the identity of the parties to the transaction, the nature
of the transferee's proposed business use for the Premises, the proposed
documentation for and terms of the transaction, and all other information
reasonably requested by Landlord concerning the proposed transaction and the
parties involved therein, including certified financial information, credit
reports, the business background and references regarding the transferee, and an
opportunity to meet and interview the transferee. Within twenty (20) days after
the later of such interview or the receipt of all such information required by
Landlord, or within thirty (30) days after the date of Tenant's request to
Landlord if Landlord does not request additional information or an interview,
Landlord shall have the right, by notice to Tenant, to: (i) consent to the
assignment or sublease, subject to the terms of this Article 17; (ii) decline to
consent to the assignment or sublease; (iii) in the case of a subletting, to
sublet from Tenant the portion of the Premises proposed to be sublet on the
terms and conditions set forth in Tenant's request to Landlord, unless the rent
terms exceed the allocable Rent payable by Tenant hereunder, in which event only
such Rent shall be payable by Landlord under such subletting; or (iv) terminate
this Lease as to the affected portion of the Premises as of the date specified
by Tenant as the effective date of the proposed assignment or sublease, in which
event Tenant will be relieved of all unaccrued obligations hereunder as to such
portion as of such date, other than those obligations which survive termination
of this Lease. If Landlord elects so to terminate, Tenant shall have the right,
by notice to Landlord within five (5) days after Landlord's exercise of such
right, to rescind its request for the proposed assignment or subletting, in
which event this Lease shall not terminate and shall remain in full force and
effect.

          17.3. Conditions for Landlord Approval. In the event Landlord elects
not to sublet from Tenant or terminate this Lease (in whole or in part) as
provided in clauses (iii) and (iv) of Section 17.2, Landlord shall not
unreasonably withhold its consent to a proposed subletting or assignment by
Tenant. Without limiting the grounds on which it may be reasonable for Landlord
to withhold its consent to an assignment or sublease, Tenant agrees that
Landlord would be acting reasonably in withholding its consent in the following
instances: (i) if Tenant is in default under this Lease; (ii) if the transferee
is a governmental or quasi-governmental agency, foreign or domestic; (iii) if
the transferee is an existing tenant in the Building; (iv) if, in Landlord's
sole judgment, the transferee's business, use and/or occupancy of the Premises
would (A) violate any of the terms of this Lease or the lease of any other
tenant in the Marketplace, or (B) not be comparable to and compatible with the
types of use by other tenants in the Building, (C) fall within any category of
use for which Landlord would not then lease space in the Building under its
leasing guidelines and policies then in effect, (D) require any Alterations
which would reduce the value of the existing leasehold improvements in the
Premises, or (E) result in increased density per floor or require increased
services by Landlord; (v) in the case of a sublease, it would result in more
than three (3) occupancies in the Premises, including Tenant and subtenants;
(vi) if the financial condition of the transferee does not meet the requirements
applied by Landlord for other tenants in the Building under leases with
comparable terms, or in Landlord's sole judgment the business reputation of the
transferee is not consistent with that of other tenants of the Building; or
(vii) in the case of a sublease, the rent payable by the subtenant is less than
the then prevailing rate being charged by Landlord for the lease of comparable
<PAGE>

space in the Building. If Landlord consents to an assignment or sublease, the
terms of such assignment or sublease transaction shall not be modified without
Landlord's prior written consent pursuant to this Article 17. Landlord's consent
to an assignment or subletting shall not be deemed consent to any subsequent
assignment or subletting.

          17.4. Costs and Expenses. As a condition to the effectiveness of any
assignment or subletting under this Article 17, Tenant shall pay to Landlord a
processing fee of Five Hundred Dollars ($500.00) and all reasonable costs and
expenses, including attorneys' fees and disbursements, incurred by Landlord in
evaluating Tenant's requests for assignment or sublease, whether or not Landlord
consents to an assignment or sublease. Tenant shall pay the processing fee with
Tenant's request for Landlord's consent and under Section 17.2. Tenant shall
also pay to Landlord all costs and expenses incurred by Landlord due to a
transferee taking possession of the Premises, including freight elevator
operations, security service, janitorial service and rubbish removal.

          17.5. Payment of Excess Rent and Other Consideration. Tenant shall
also pay to Landlord, promptly upon Tenant's receipt thereof, one hundred
percent (100%) of any and all rent, sums or other consideration, howsoever
denominated, realized by Tenant in connection with any assignment or sublease
transaction in excess of the Base Rent and Escalation Rent payable hereunder
(prorated to reflect the Rent allocable to the portion of the Premises if a
sublease), after first deducting, (i) in the case of an assignment, the
unamortized reasonable cost of Alterations paid for by Tenant and reasonable
real estate commissions paid by Tenant in connection with such assignment and,
(ii) in the case of a sublease, the reasonable cost of Alterations made to the
Premises at Tenant's cost to effect the sublease, and the reasonable amount of
any real estate commissions paid by Tenant, both amortized over the term of the
sublease.

          17.6. Assumption of Obligations; Further Restrictions on Subletting.
Each assignee shall, concurrently with any assignment, assume all obligations of
Tenant under this Lease. Each sublease shall be made subject to this Lease and
all of the terms, covenants and conditions contained herein, and the surrender
of this Lease by Tenant, or a mutual cancellation thereof, or the termination of
this Lease in accordance with its terms, shall not work a merger and shall, at
the option of Landlord, terminate all or any existing subleases or operate as an
assignment to Landlord of any or all such sublease. No sublessee (other than
Landlord) shall have the right further to sublet. Any assignment by a sublease
of its sublease shall be subject to Landlord's prior consent in the same manner
as a sublease by Tenant. No sublease, once consented to by Landlord, shall be
modified without Landlord's prior consent. No assignment or sublease shall be
binding on Landlord unless the transferee delivers to Landlord a fully executed
counterpart of the assignment or sublease which contains the assumption by the
assignee, or recognition by the sublease, of the provisions of this Section
17.6, in form and substance satisfactory to Landlord, but the failure or refusal
of a transferee to deliver such instrument shall not release or discharge such
transferee from the provisions and obligations of this Section 17.6, but such
failure shall constitute a default by Tenant under this Lease.

          17.7. No Release. No assignment or sublease shall release Tenant from
its obligations under this Lease, whether arising before or after the assignment
or sublease. The acceptance of Rent by Landlord from any other person shall not
be deemed a waiver by Landlord of any provision of this Article 17. On a default
by any assignee of Tenant in the performance of any of the terms, covenants or
conditions of this Lease, Landlord may proceed directly against Tenant without
the necessity of commencing or exhausting remedies against such assignee. No
consent by Landlord to any further assignments or sublettings of this Lease, or
any modification, amendment or termination of this Lease, or extension, waiver
or modification of payment or any other obligations under this Lease, or any
other action by Landlord with respect to any assignee or sublessee, or the
insolvency, or bankruptcy or default of any such assignee or sublessee, shall
affect the continuing liability of Tenant for its obligations under this Lease
and Tenant waives any defense arising out of or based thereon, including any
suretyship defense of exoneration. Landlord shall have no obligation to notify
Tenant or obtain Tenant's consent with respect to any of the foregoing matters.

          17.8. No Encumbrance. Notwithstanding anything to the contrary
contained in this Article 17, Tenant shall have no right to encumber, pledge,
hypothecate or otherwise transfer this Lease, or any of Tenant's interest or
rights hereunder, as security for any obligations or liability of Tenant.

     18.  Rules and Regulations. Tenant shall observe and comply, and shall
cause its sublessees, employees, agents, contractors, licensees and invitees to
observe and comply, with the Rules and Regulations of the Marketplace, a copy of
which are attached to this Lease as Exhibit D, and, after notice thereof, with
all modifications and additions thereto from time to time promulgated in writing
by Landlord. Landlord shall not be responsible to Tenant, or Tenant's
sublessees, employees, agents, contractors, licensees or invitees, for
noncompliance with any Rules and Regulations of the Marketplace by any other
tenant, sublessee, employee, agent, contractor,
<PAGE>

licensee, invitee or other occupant of the Marketplace. Landlord shall use
reasonable efforts to enforce the Rules and Regulations in a non-discriminatory
manner.

     19. Entry of Premises by Landlord.

          19.1. Right to Enter. Upon twenty-four hour advance notice to Tenant
(except in emergencies or in order to provide regularly scheduled or other
routine Building standard services or additional services requested by Tenant,
or post notices of nonresponsibility or other notices permitted or required by
law when no such notice shall be required), Landlord and its authorized agents,
employees, and contractors may enter the Premises at reasonable hours to: (i)
inspect the same; (ii) determine Tenant's compliance with its obligations
hereunder; (iii) exhibit the same to prospective purchasers, lenders or tenants;
(iv) supply any services to be provided by Landlord hereunder; (v) post notices
of nonresponsibility or other notices permitted or required by law, (vi) make
repairs, improvements or alterations, or perform maintenance in or to, the
Premises or any other portion of the Marketplace, including Building systems;
and (vii) perform such other functions as Landlord deems reasonably necessary or
desirable. Landlord may also grant access to the Premises to government or
utility representatives and bring and use on or about the Premises such
equipment as reasonably necessary to accomplish the purposes of Landlord's
entry. Landlord shall use reasonable good faith efforts to effect all entries
and perform all work hereunder in such manner as to minimize interference with
Tenant's use and occupancy of the Premises. Landlord shall have and retain keys
with which to unlock all of the doors in or to the Premises (excluding Tenant's
vaults, safes and similar secure areas designated in writing by Tenant in
advance), and Landlord shall have the right to use any and all means which
Landlord may deem proper in an emergency in order to obtain entry to the
Premises including secure areas.

          19.2. Tenant Waiver of Claims. Tenant Waives any claim for damages for
any inconvenience to or interference with Tenant's business, or any loss of
occupancy or quiet enjoyment of the Premises, or any other loss, occasioned by
any entry effected or work performed under this Article 19, and Tenant shall not
be entitled to any abatement of Rent by reason of exercise of any such right of
entry or performance of such work. No entry to the Premises by Landlord or
anyone acting under Landlord shall constitute a forcible or unlawful entry into,
or a detainer of, the Premises or any eviction, actual or constructive of Tenant
from the Premises, or any portion thereof.

     20.  Default and Remedies.

          20.1. Events of Default. The occurrence of any of the following events
shall constitute a default by Tenant under this Lease:

               a. Nonpayment of Rent. Failure to pay any Rent when due.

               b. Unpermitted Assignment. An assignment or sublease made in
contravention of any of the provisions of Article 17 above.

               c. Other Obligation. Failure to perform or fulfill any other
obligation, covenant, condition or agreement under this Lease.

               d. Bankruptcy and Insolvency. A general assignment by Tenant for
the benefit of creditors, any action or proceeding commenced by Tenant under any
insolvency or bankruptcy act or under any other statute or regulation for
protection from creditors, or any such action commenced against Tenant and not
discharged within thirty (30) days after the date of commencement; the
employment or appointment of a receiver or trustee to take possession of all or
substantially all of Tenant's assets or the Premises; the attachment, execution
or other judicial seizure of all or substantially all of Tenant's assets or the
Premises, if such attachment or other seizure remains undismissed or
undischarged for a period of ten (10) days after the levy thereof; the admission
by Tenant in writing of its inability to pay its debts as they become due; or
the filing by Tenant of a petition seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, the filing by Tenant of an answer
admitting or failing timely to contest a material allegation of a petition filed
against Tenant in any such proceeding or, if within thirty (30) days after the
commencement of any such proceeding against Tenant, such proceeding is not
dismissed. For purposes of this Section 20.1(d), "Tenant" means Tenant and any
partner of Tenant, if Tenant is a partnership, or any person or entity
comprising Tenant, if Tenant is comprised of more than one person or entity, or
any guarantor of Tenant's obligations, or any of them, under this Lease.
<PAGE>

     20.2.  Notice to Tenant. Upon the occurrence of any default, Landlord shall
give Tenant notice thereof. Such notice shall replace rather than supplement any
equivalent or similar statutory notice, including any notices required by
California Code of Civil Procedure Section 1161 or any similar or successor
statute; and giving of such notice in the manner required by Article 28 shall
replace and satisfy any service-of-notice procedures set forth in any statute,
including those required by California Code of Civil Procedure Section 1162 or
any similar or successor statute. If a time period is specified below for cure
of such default, then Tenant may cure such default within such time period. To
the fullest extent allowed by law, Tenant hereby waives any right under law now
or hereinafter enacted to any other time period for cure of default.

            a.  Nonpayment of Rent. For failure to pay Rent, within five (5)
days after Landlord's notice, unless Tenant has failed more than two (2) times
during any calendar year timely to pay any Rent, in which event no cure period
shall apply for the balance of such calendar year.

            b.  Other Obligations. For failure to perform any obligation,
covenant, condition or agreement under this Lease (other than nonpayment of
Rent, an assignment or subletting in violation of Article 17 or Tenant's
abandonment of the Premises) within ten (10) days after Landlord's notice or, if
the failure is of a nature requiring more than ten (10) days to cure, then an
additional thirty (30) days after the expiration of such 10-day period, but only
if Tenant commences cure within such 10-day period and thereafter diligently
pursues such cure to completion within such additional 30-day period. If Tenant
has failed to perform any such obligation, covenant, condition or agreement more
than two (2) times during any calendar year and notice of such event of default
has been given by Landlord in each instance, then no cure period shall apply for
the balance of such calendar year.

            c.  No Cure Period. No cure period shall apply for any other event
of default specified in Section 20.1.

     20.3.  Remedies Upon Occurrence of Default. On the occurrence of a default
which Tenant fails to cure after notice and expiration of the time period for
cure, if any, specified in Section 20.2. above, Landlord shall have the right
either (i) to terminate this Lease and recover possession of the Premises, or
(ii) to continue this Lease in effect and enforce all Landlord's rights and
remedies under California Civil Code Section 1951.4 (by which Landlord may
recover Rent as it becomes due, subject to Tenant's right to assign pursuant to
Article 17). Landlord may store any property of Tenant located in the Premises
at Tenant's expense or otherwise dispose of such property in the manner provided
by law. If Landlord does not terminate this Lease, Tenant shall in addition to
continuing to pay all Rent when due, also pay Landlord's costs of attempting to
relet the Premises, any repairs and alterations necessary to prepare the
Premises for such reletting, and brokerage commissions and attorney's fees
incurred in connection therewith, less the rents, if any, actually received from
such reletting. Notwithstanding Landlord's election to continue this Lease in
effect, Landlord may at any time thereafter terminate this Lease pursuant to
this Section 20.3.

     20.4.  Damages Upon Termination. If and when Landlord terminates this Lease
pursuant to Section 20.3. Landlord may exercise all its rights and remedies
available under California Civil Code Section 1951.2, including the right to
recover from Tenant the worth at the time of award of the amount by which the
unpaid Rent for the balance of the Term after the time of award exceeds the
amount of such Rent loss that the Tenant proves could have been reasonably
avoided. As used herein and in Civil Code Section 1951.2, "time of award" means
either the date upon which Tenant pays to Landlord the amount recoverable by
Landlord, or the date of entry of any determination, order or judgment of any
court or other legally constituted body determining the amount recoverable,
whichever occurs first.

     20.5.  Computation of Certain Rent for Purposes of Default. For purposes of
computing unpaid Rent pursuant to Section 20.4 above, Escalation Rent for the
balance of the Term shall be determined by averaging the amount paid by Tenant
as Escalation Rent for the calendar year prior to the year in which the default
occurred (or, if the prior year is the Base Year or such default occurs during
the Base Year, Escalation Rent shall be based on Landlord's operating budget for
the Building for the Base Year), increasing such average amount for each
calendar year (or portion thereof) remaining in the balance of the Term at a per
annum compounded rate equal to the mean average rate of increase for the
preceding five (5) calendar years in the United States Department of Labor,
Bureau of Labor Statistics, Consumer Price Index (All Urban Consumers, All
Items, 1982-1984 = 100) for the Metropolitan Area of which San Francisco,
California, is a part, and adding together the resulting amounts. If such Index
is discontinued or revised, such computation shall be made by reference to the
index designated as the successor or substitute index by the United States
Department of Labor, Bureau of Labor Statistics, or its successor agency, and if
none is designated, by a comparable index as determined by Landlord in its sole
discretion, which would likely achieve a comparable result to that achieved by
the use of the Consumer Price Index. If the base year of the Consumer Price
Index is changed, then the conversion factor specified by the Bureau, or
successor agency, shall be utilized to determine the Consumer Price Index.
<PAGE>

       20.6.  Landlord's Right to Cure Defaults. If Tenant fails to pay Rent
(other than Base Rent and Escalation Rent) required to be paid by it hereunder,
or fails to perform any other obligation under this Lease, and Tenant fails to
cure such default within the applicable cure period, if any, specified in
Section 20.2 above, then Landlord may, without waiving any of Landlord's rights
in connection therewith or releasing Tenant from any of its obligations or such
default, make any such payment or perform such other obligation on behalf of
Tenant. All payments so made by Landlord, and all costs and expenses incurred by
Landlord to perform such obligations, shall be due and payable by Tenant as Rent
immediately upon receipt of Landlord's demand therefor.

       20.7. Remedies Cumulative. The rights and remedies of Landlord under this
Lease are cumulative in addition to, and not in lieu of, any other rights and
remedies available to Landlord at law or in equity. Landlord's pursuit of any
such right or remedy shall not constitute a waiver or election of remedies with
respect to any other right or remedy.

   21. Subordination, Attornment and Nondisturbance.

       21.1. Subordination and Attornment This Lease and all of Tenant's rights
hereunder shall be subordinate to any ground lease or underlying lease, and the
lien of any mortgage, deed of trust, or any other security instrument now or
hereafter affecting or encumbering the Marketplace, or any part thereof or
interest therein, and to any and all advances made on the security thereof or
Landlord's interest therein, and to all renewals, modifications, consolidations,
replacements and extensions thereof (an "encumbrance", the holder of the
beneficial interest thereunder being referred to as an "encumbrancer"). An
encumbrancer may, however, subordinate its encumbrance to this Lease, and if an
encumbrancer so elects by notice to Tenant, this Lease shall be deemed prior to
such encumbrance. If any encumbrance to which this Lease is subordinate is
foreclosed, or a deed in lieu of foreclosure is given to the encumbrancer
thereunder, Tenant shall attorn to the purchaser at the foreclosure sale or to
the grantee under the deed in lieu of foreclosure; and if any encumbrance
consisting of a ground lease or underlying lease to which this Lease is
subordinate is terminated, Tenant shall attorn to the lessor thereof. Tenant
shall execute, acknowledge and deliver in the form requested by Landlord or any
encumbrancer, any documents required to evidence or effectuate the subordination
hereunder, or to make this Lease prior to the lien of any encumbrance, or to
evidence such attornment.

        21.2  Nondisturbance. If any encumbrance to which this Lease is
subordinate is foreclosed, or a deed in lieu of foreclosure is given to the
encumbrancer thereunder, or if any encumbrance consisting of a ground lease or
underlying lease to which this Lease is subordinate is terminated, this Lease
shall not terminate, and the rights and possession of Tenant under this Lease
shall not be disturbed if (i) no default by Tenant then exists under this Lease;
(ii) Tenant attorns to the purchaser, grantee, or successor lessor as provided
in Section 21.1 above or, if requested, enters into a new lease for the balance
of the Term upon the same terms and provisions contained in this Lease; and
(iii) Tenant enters into a written agreement in a form reasonably acceptable to
such encumbrancer with respect to subordination, attornment and non-disturbance.

   22.  Sale or Transfer by Landlord; Lease Non-Recourse.

        22.1  Release of Landlord on Transfer. Landlord may at any time
transfer, in whole or in part, its right, title and interest under this Lease
and in the Marketplace, or any portion thereof. If the original Landlord
hereunder, or any successor to such original Landlord, transfers (by sale,
assignment or otherwise) its right, title or interest in the Building, all
liabilities and obligations of the original Landlord or such successor under
this Lease accruing after such transfer shall terminate, the original Landlord
or such successor shall automatically be released therefrom, and thereupon all
such liabilities and obligations shall be binding upon the new owner. Tenant
shall attorn to each such new owner.

        22.2  Lease Nonrecourse to Landlord. Landlord shall in no event be
personally liable under this Lease, and Tenant shall look solely to Landlord's
interest in the Building, for recovery of any damages for breach of this Lease
by Landlord or on any judgment in connection therewith. None of the persons or
entities comprising or representing Landlord (whether partners, shareholders,
officers, directors, trustees, employees, beneficiaries, agents or otherwise)
shall ever be personally liable under this Lease or liable for any such damages
or judgment and Tenant shall have no right to effect any levy of execution
against any assets of such persons or entities on account of any such liability
or judgment. Any lien obtained by Tenant to enforce any such judgment, and any
levy of execution thereon, shall be subject and subordinate to all encumbrances
as specified in Article 21 above.

   23.  Estoppel Certificate.
<PAGE>

        23.1. Procedure and Content. From time to time, and within ten (10) days
after written notice by Landlord, Tenant shall execute, acknowledge, and deliver
to Landlord a certificate as specified by Landlord certifying: (i) that this
Lease is unmodified and in full force and effect (or, if there have been
modifications, that this Lease is in full force and effect, as modified, and
identifying each modification); (ii) the Commencement Date and Expiration Date;
(iii) that Tenant has accepted the Premises (or the reasons Tenant has not
accepted the Premises), and if Landlord has agreed to make any alterations or
improvements to the Premises, that Landlord has properly completed such
alterations or improvements (or the reasons why Landlord has not done so); (iv)
the amount of the Base Rent and current Escalation Rent, if any, and the date to
which such Rent has been paid; (v) that Tenant has not committed any event of
default, except as to any events of default specified in the certificate, and
whether there are any existing defenses against the enforcement of Tenant's
obligations under this Lease; (vi) that no default of Landlord id claimed by
Tenant, except as to any defaults specified in the certificate; and (vii) such
other matters as may be requested by Landlord.

        23.2  Effect of Certificate. Any such certificate may be relied upon by
any prospective purchaser of any part or interest in the Marketplace or
encumbrancer (as defined in Section 21.1) and, at Landlord's request, Tenant
shall deliver such certificate to Landlord and/or to any such entity and shall
agree to such notice and cure provisions and such other matters as such entity
may reasonably require. In addition, at Landlord's request, Tenant shall provide
to Landlord for delivery to any such entity such information, including
financial information, that may reasonably be requested by any such entity. Any
such certificate shall constitute a waiver by Tenant of any claims Tenant may
have in contravention to the information contained in such certificate and
Tenant shall be estopped from asserting any such claim. If Tenant fails or
refuses to give a certificate hereunder within the time period herein specified,
then the information contained in such certificate as submitted by Landlord
shall be deemed correct for all purposes, but Landlord shall have the right to
treat such failure or refusal as a default by Tenant. Any prospective purchaser
or encumbrancer shall sign a confidentiality agreement regarding the non-
disclosure of Tenant's financial information prior to delivery of such
information to the prospective purchaser or encumbrancer.

   24.  No Light, Air or View Easement. Nothing contained in this Lease shall be
deemed, either expressly or by implication, to create any easement for light and
air or access to any view. Any diminution or shutting off of light, air or view
to or from the Premises by any structure which now exists or which may hereafter
be erected, whether by Landlord or any other person, shall in no way affect this
Lease or Tenant's obligations hereunder, entitle Tenant to any reduction of
Rent, or impose any liability on Landlord.

   25.  Holding Over. No holding over by Tenant shall operate to extend the
Term. If Tenant remains in possession of the Premises after expiration or
termination of this Lease, unless otherwise agreed by Landlord in writing, then
(i) Tenant shall become a tenant at sufferance upon all the applicable terms and
conditions of this Lease, except that Base Rent shall be increased to equal 200%
of the Base Rent then in effect, (ii) Tenant shall indemnify, defend, protect
and hold harmless Landlord, and any tenant to whom Landlord has leased all or
part of the Premises, from any and all liability, loss, damages, costs or
expense (including loss of Rent to Landlord or additional rent payable by such
tenant and reasonable attorneys' fees) suffered or incurred by either Landlord
or such tenant resulting from Tenant's failure timely to vacate the Premises;
and (iii) such holding over by Tenant shall constitute a default by Tenant.

   26.  Security Deposit.

        26.1  Deposit Required; Adjustment to Amount of Security Deposit. Tenant
shall deposit with Landlord the Initial Security Deposit upon the execution of
this Lease by Tenant. On or before July 1, 1999, Tenant shall either (i) provide
written evidence, certified to be true, correct and complete by an authorized
officer of Tenant and otherwise satisfactory to Landlord, that Tenant has raised
equity in addition to that shown on Tenant's financial statement dated December
31, 1998 in the amount of at least Four Million and 00/100 Dollars
($4,000,000.00) (the "Additional Capital") or (ii) deposit with Landlord Twenty
Two Thousand Five Hundred and 00/100 Dollars ($22,500.00) (the "Additional
Security Deposit") in addition to the Initial Security Deposit that Tenant
deposited with Landlord upon execution of the Lease. For purposes of this Lease,
the term "Security Deposit" as used herein shall refer only to the Initial
Security Deposit prior to July 1, 1999, and on and after July 1, 1999, the term
"Security Deposit" shall refer to both the Initial Security Deposit and the
Additional Security Deposit (to the extent Tenant is required to deposit with
Landlord the Additional Security Deposit as provided above). If Tenant fails to
provide to Landlord satisfactory evidence of the Additional Capital on or before
July 1, 1999 and fails to deposit the Additional Security Deposit with Landlord
on or before July 1, 1999, monthly Base Rent shall increase to Fifteen Thousand
Six Hundred Forty Seven and 00/100 ($15,647.00) commencing on July 1, 1999. If
Tenant raises the Additional Capital after July 1, 1999, Landlord shall return
the Additional Security Deposit provided that Tenant shall have provided written
evidence of the Additional Capital, certified to be true, correct and complete
by an authorized officer of Tenant and otherwise satisfactory to Landlord.
<PAGE>

        26.2  Consequence of Default. The Security Deposit shall be held by
Landlord as security for the performance by Tenant of all its obligations under
this Lease. If Tenant fails to pay any Rent due hereunder, or otherwise commits
a default with respect to any provision of this Lease, Landlord may use, apply
or retain all or any portion of the Security Deposit for the payment of any such
Rent or for the payment of any other amounts expended or incurred by Landlord by
reason of Tenant's default, or to compensate Landlord for any loss or damage
which Landlord may incur thereby (and in this regard Tenant hereby waives the
provisions of California Civil Code Section 1950.7(c) and any similar or
successor statute providing that Landlord may claim from a security deposit only
those sums reasonably necessary to remedy defaults in the payment of Rent, to
repair damage caused by Tenant, or to clean the Premises). Exercise by Landlord
of its rights hereunder shall not constitute a waiver of, or relieve Tenant from
any liability for, any default. If Tenant performs all of Tenant's obligations
hereunder, the Security Deposit, or so much thereof as has not theretofore been
applied by Landlord, shall be returned, without interest, to Tenant (or, at
Landlord's option, to the last assignee, if any, of Tenant's interest under this
Lease) within thirty (30) days after the later of (i) the date of expiration or
earlier termination of this Lease, or (ii) vacation of the Premises by Tenant if
the Premises has been left in the condition specified by this Lease. Landlord's
receipt and retention of the Security Deposit shall not create any trust or
fiduciary relationship between Landlord and Tenant and Landlord need not keep
the Security Deposit separate from its general accounts. Upon termination of the
original Landlord's (or any successor owner's) interest in the Premises, the
original Landlord (or such successor) shall be released from further liability
with respect to the Security Deposit upon the original Landlord's (or such
successor's) compliance with California Civil Code Section 1950.7(d), or
successor statute.

   27.  Waiver.  Failure of Landlord to declare a default by Tenant upon
occurrence thereof, or delay in taking any action in connection therewith, shall
not waive such default, but Landlord shall have the right to declare such
default at any time after its occurrence. To be effective, a waiver of any
provision of this Lease, or any default, shall be in writing and signed by the
waiving party. Any waiver hereunder shall not be deemed a waiver of subsequent
performance of any such provision or subsequent defaults. The subsequent
acceptance of Rent hereunder, or endorsement of any check by Landlord, shall not
be deemed to constitute an accord and satisfaction or a waiver of any preceding
default by Tenant, except as to the particular Rent so accepted, regardless of
Landlord's knowledge of the preceding default at the time of acceptance of the
Rent. No course of conduct between Landlord and Tenant, and no acceptance of the
keys to or possession of the Premises by Landlord before the Expiration Date
shall constitute a waiver of any provision of this Lease or of any default, or
operate as a surrender of this Lease.

   28.  Notice and Consents; Tenant's Agent for Service. All notices, approvals,
consents, demands and other communications from one party to the other given
pursuant to this Lease shall be in writing and shall be made by personal
delivery, by use of a reputable overnight courier service or by deposit in the
United States mail, certified, registered or Express, postage prepaid and return
receipt requested. Notices shall be addressed if to Landlord, to Landlord's
Address, and if to Tenant, to Tenant's Address. Landlord and Tenant may each
change their respective Addresses from time to time by giving written notice to
the other of such change in accordance with the terms of this Article 28, at
least ten (10) days before such change is to be effected. Any notice given in
accordance with this Article 28 shall be deemed to have been given (i) on the
date of personal delivery or (ii) on the earlier of the date of delivery or
attempted delivery (as shown by the return receipt or other delivery record) if
sent by courier service or mailed.

   29.  Tenant's Authority. Tenant, and each of the persons executing this Lease
on behalf of Tenant, represent and warrant that (i) Tenant is a duly formed,
authorized and existing corporation, partnership or trust (as the case may be),
(ii) Tenant is qualified to do business in California, (iii) Tenant has the full
right and authority to enter into this Lease and to perform all of Tenant's
obligations hereunder, and (iv) each person signing on behalf of Tenant is
authorized to do so. Tenant shall deliver to Landlord, upon Landlord's request,
such certificates, resolutions, or other written assurances authorizing Tenant's
execution and delivery of this Lease, and such financial information regarding
Tenant and its constituent members, as requested by Landlord from time to time
or at any time in order for Landlord to assess Tenant's then authority and/or
ability to meet its obligations under this Lease.

   30.  Automobile Parking.

        30.1.  Tenant Appurtenant Parking Rights. Subject to the terms and
conditions contained in this Article 30, Landlord shall make available to Tenant
parking spaces in the parking areas designated by Landlord for parking in the
Marketplace (such areas being hereinafter collectively referred to as the
"Parking Facility"). For purposes of this Lease, the term "Minimum Spaces" shall
mean an amount equal to four (4) parking space for each 1,000 square feet of
Rentable Area leased by Tenant in the Building. Tenant shall at all times
provide to Landlord, upon Landlord's request, a list of all of the vehicle
makes, colors and license plate numbers of all vehicles of Tenant's employees.
Tenant's use of the parking spaces to be made available to Tenant shall be on a
non-exclusive basis in common with other tenants in the Marketplace; and parking
in such spaces shall be on a first-come-first-served, unassigned, non-reserved
basis. The parking spaces to be made available to Tenant shall be in locations
designated by Landlord; and Landlord reserves
<PAGE>

the right to designate different locations from time to time without any
liability to Tenant and Tenant agrees that any such designation of a different
location shall not give rise to any claims or offset against Landlord hereunder.
Without limiting the generality of the foregoing, Landlord may restrict certain
portions of the Parking Facility for the exclusive use of one or more tenants of
the Marketplace (and their employees and agents) and may designate other areas
in the Parking Facility to be used at large only by licensees, customers and
invitees of tenants of the Marketplace; and Landlord may in its sole and
absolute discretion restrict or prohibit the use of the Parking Facility by any
vehicles other than passenger automobiles such as full-sized vans or trucks.
Notwithstanding the foregoing, Landlord shall not exercise any of the foregoing
rights in a manner which would permanently reduce the total number of parking
spaces available to Tenant on a non-exclusive basis to a number less than the
Minimum Spaces. Tenant shall not permit any vehicles belonging to Tenant or any
of Tenant's subtenants or any of their respective employees, agents, customers,
contractors or invitees to be loaded, unloaded or parked in areas other than
those designated by Landlord for such activities. In its use of the Parking
Facilities Tenant shall comply (and shall cause each of its subtenants and each
of their respective employees, agents, customers, contractors and invitees to
comply) with any and all parking regulations and rules established from time to
time by Landlord or Landlord's parking operator. Landlord or Landlord's parking
operator shall have the right to cause to be removed any vehicles of Tenant, its
subtenants or any of their respective employees, agents, licesees, customers or
invitees, that are parked in violation of any of the provisions of this Article
30 or of the regulations and rules then established by Landlord, and to charge
all of the costs incurred by Landlord in connection with such removal to Tenant
and Tenant shall pay the amount of all such costs to Landlord as additional rent
within five (5) days after receipt of written demand from Landlord. Any such
removal shall be without liability of any kind to Landlord or Landlord's parking
operator or their respective employees or agents; and Tenant shall protect,
defend, indemnify and hold Landlord and Landlord's parking operator and their
respective employees and agents from and against any and all claims, losses,
damages, demands, costs and expenses (including reasonable attorneys' fees)
which may be asserted against or incurred by any of such indemnified parties
arising out of or in connection with such removal of any automobiles.

        30.2.  Parking Fee. During the initial Term, Landlord shall impose no
charge on Tenant for use of the Parking Facility. After the expiration of the
initial Term, Landlord shall have the right to impose on Tenant a charge for the
use of the Parking Facility. If Landlord imposes any such parking fee (the "Base
Parking Fee") after the expiration of the initial Term, then on the first day of
each and every calendar month thereafter, Tenant shall pay to Landlord the Base
Parking Fee for each parking space utilized by employees of Tenant or its
subtenants. If Tenant shall fail to pay the Base Parking Fee to Landlord as and
when required, Tenant shall have no further right to utilize the parking spaces
for which Tenant shall have failed to pay the Base Parking Fee. Landlord
reserves the right to separately charge Tenant's guests and visitors for
parking. Landlord or Landlord's parking operator shall have the right from time
to time to adjust the amount of the Base Parking Fee to the then-prevailing fair
market rate as reasonably determined by Landlord or its parking operator. Any
such adjustment shall be effective as of the first day of the first calendar
month following Tenant's receipt of such adjustment from Landlord. If any
governmental authority having jurisdiction charges Landlord a fee for parking
during the Term, Landlord shall have the right to include as Operating Expenses
such parking fees.

        30.3   Allocation of Risk. Landlord shall have no obligation to monitor
the use of the Parking Facility. The use of the Parking Facility by the
employees of Tenant and its subtenants shall be at the sole risk of Tenant, its
subtenants and their respective employees. Unless caused by the sole active
gross negligence or willful misconduct of Landlord, Landlord shall have no
responsibility or liability for any injury or damage to any person or property
by or as a result of the use of the Parking Facility by Tenant and its
subtenants and their respective employees, whether by theft, collision, criminal
activity, or otherwise; and Tenant hereby assumes, for itself, its subtenants
and their respective employees, all risks associated with any such occurrences
in or about the Parking Facility.

   31.  Tenant to Furnish Financial Statements. In order to induce Landlord to
enter into this Lease, Tenant agrees that it shall promptly deliver to Landlord,
from time to time, upon Landlord's written request, financial statements
(including a balance sheet and statement of income and expenses on an annualized
basis) reflecting Tenant's then current financial condition. Such statements
shall be delivered to Landlord within fifteen (15) days after Tenant's receipt
of Landlord's request. Tenant represents and warrants that all financial
statements, records, and information furnished by Tenant to Landlord in
connection with this Lease are and shall be true, correct and complete in all
respects.

   32.  Tenant's Signs. Without Landlord's prior consent, which Landlord may
withhold in its sole discretion, Tenant shall not place on the Premises or on
the Building any exterior signs nor any interior signs that are visible from the
exterior of the Premises or Building. Tenant shall pay all costs and expenses
relating to any such sign approved by Landlord, including without limitation,
the cost of the installation and maintenance of the sign. On the date of
expiration or earlier termination of this Lease, Tenant, at its sole cost and
expense, shall remove all signs and repair any damage caused by such removal.
<PAGE>

   33.  Miscellaneous.

        33.1. No Joint Venture. This Lease does not create any partnership or
joint venture or similar relationship between Landlord and Tenant.

        33.2. Successors and Assigns. Subject to the provisions of Article 17
regarding assignment, all of the provisions, terms, covenants and conditions
contained in this Lease shall bind, and inure to the benefit of, the parties and
their respective successors and assigns.

        33.3. Construction and Interpretation. The words "Landlord" and "Tenant"
include the plural as well as the singular. If there is more than one person
comprising Tenant, the obligations under this Lease imposed on Tenant are joint
and several. References to a party or parties refers to Landlord or Tenant, or
both, as the context may require. The captions preceding the Articles, Sections
and subsections of this Lease are inserted solely for convenience of reference
and shall have no effect upon, and shall be disregarded in connection with the
construction and interpretation of this Lease. Use in this Lease of the words
"including", "such as", or words of similar import when following a general
manner, shall not be construed to limit such matter to the enumerated items or
matters whether or not language of nonlimitation (such as "without limitation")
is used with reference thereto. All provisions of this Lease have been
negotiated at arm's length between the parties and after advice by counsel and
other representatives chosen by each party and the parties are fully informed
with respect thereto. Therefore, this Lease shall not be construed for or
against either party by reason of the authorship or alleged authorship of any
provision hereof, or by reason of the status of the parties as Landlord or
Tenant, and the provisions of this Lease and the Exhibits hereto shall be
construed as a whole according to their common meaning in order to effectuate
the intent of the parties under the terms of this Lease.

        33.4  Severability. If any provision of this Lease, or the application
thereof to any person or circumstance, is determined to be illegal, invalid or
unenforceable, the remainder of this Lease, or its application to persons or
circumstances other than those as to which it is illegal, invalid or
unenforceable, shall not be affected thereby and shall remain in full force and
effect, unless enforcement of this Lease as so invalidated would be unreasonable
or grossly inequitable under the circumstances, or would frustrate the purposes
of this Lease.

        33.5  Entire Agreement; Amendments. This Lease, together with the
Exhibits hereto and any Addenda identified on the Basic Lease Information,
contains all the representations and the entire agreement between the parties
with respect to the subject matter hereof and any prior negotiations,
correspondence, memoranda, agreements, representations or warranties are
replaced in total by this Lease, the Exhibits hereto and such Addenda. Neither
Landlord nor Landlord's agents have made any warranties or representations with
respect to the Premises or any other portion of the Marketplace, except as
expressly set forth in this Lease. This Lease may be modified or amended only by
an agreement in writing signed by both parties.

                                   EXHIBIT C

                         TENANT IMPROVEMENT AGREEMENT

This Tenant Improvement Agreement ("Agreement") is part of the Lease ("Lease")
relating to certain premises (defined therein as the "Initial Premises" and the
"Expansion Area" and collectively as the "Premises") which are more particularly
shown in Exhibit A of the Lease. Landlord and Tenant agree as follows with
respect to the Improvements to be installed in the Premises (the "Tenant
Improvements"):

1. PLANS AND SPECIFICATIONS

   A. General Parameters. The plans and specifications for the construction of
      the Tenant Improvements shall be developed by Landlord and Tenant. In
      developing the preliminary space plans (the "Space Plans"), final space
      plans and working drawings, and in determining whether any change orders
      shall be requested, Tenant's architect shall initially create such plans
      and drawings, with the input of Landlord and/or Landlord's architect, and
      any plans shall be subject to the approval of Landlord and its architect
      which may be withheld in the subjective, good faith, discretion of
      Landlord. Landlord and Tenant acknowledge that the design and aesthetic
      characteristics of the Tenant Improvements are an important consideration
      to Landlord. The parties further acknowledge that matters of aesthetics
      are not easily reduced to an "objective" reasonableness standard. Landlord
      agrees, however, that its actions with respect to the approval or
      disapproval of the Plans shall be made in good faith. Accordingly, the
      parties intend that the "subjective, good faith," standards set forth in
      this Lease for Landlord's review and approval of the plans shall take into
      account Landlord's right to exercise its subjective aesthetic judgement in
      a good faith manner. In addition to the foregoing, Tenant agrees that the
      plans shall include acoustical separation requested by Landlord in the
      walls separating the Premises from the remainder of the Building. Tenant
      shall cause all plans, drawings and specifications for the Tenant
      Improvements, whether preliminary or final, to be prepared by licensed
      architects and, where appropriate, licensed mechanical, electrical and
      structural engineers.

  B.  Preparation of Space Plans. Within ten (10) days after the full execution
      of the Lease, Tenant shall prepare and submit to Landlord two sets of
      comprehensive Space Plans. The Space Plans shall be subject to Landlord's
      prior written approval in accordance with the provisions of this Work
      Letter. Within ten (10) days after receipt of the Space Plans, Landlord
      shall return one set of the same with Landlord's approval noted thereon
      (which approval may be subject to landlord's suggested modifications), or
      with Landlord's disapproval noted thereon (which disapproval shall be
      accompanied by Landlord's suggested modifications). If Landlord has
      approved the Space Plans subject to modifications, such modifications
      shall be deemed to be acceptable to and approved by Tenant, unless Tenant
      shall prepare and resubmit to Landlord, within an additional ten (10)
      days, revised space Plans for further consideration by Landlord. If
      Landlord has disapproved the Space Plans, Tenant shall promptly prepare
      and resubmit to Landlord revised Space Plans, with changes highlighted,
      and Landlord shall approve or disapprove the same within ten (10) days
      after receipt thereof.

  C.  Working Drawings. Within twenty (20) days after the approval of the Space
      Plans by Landlord, Tenant shall prepare and submit to Landlord two sets of
      (i) fully dimensioned scale drawings for the Tenant Improvements
      (including plans, elevations, sections, perspective renderings and sample
      boards), and (ii) specifications for the Tenant Improvements (including a
      specification and justification of Tenant's utility requirements)
      (collectively, the "Working Drawings"). The Working Drawings shall be
      subject to Landlord's written approval, which approval shall not be
      unreasonably withheld. Within ten (10) business days after receipt of the
      Working Drawings, Landlord shall return one set of the same with
      Landlord's approval noted thereon (which approval may be subject to
      Landlord's suggested modifications), or with Landlord's disapproval noted
      thereon (which disapproval shall be accompanied by Landlord's suggested
      modifications). If Landlord has approved the Working Drawings subject to
      modifications, such modifications shall be deemed to be acceptable to and
      approved by Tenant, unless Tenant shall prepare and resubmit revised
      Working Drawings for further consideration by Landlord within ten (10)
      days after receipt of Landlord's comments. If Landlord has disapproved the
      Working Drawings, Tenant shall promptly prepare and resubmit revised
      Working Drawings, with changes highlighted, to Landlord and Landlord shall
      approve or disapprove the same within ten (10) business days after receipt
      thereof. The Working Drawings which have been approved by Landlord and
      Tenant are hereinafter referred to as the "Approved Working Drawings."
<PAGE>

  D.  Landlord's Approval. Landlord, in its sole discretion, may withhold its
      approval of any plans (including any change orders affecting such
      documents), to the extent such documents require work that:

      (i)   Landlord reasonably believes will increase the cost of operation or
            maintenance of any of the systems of the Building;

      (ii)  does not conform to applicable building code or is not approved by
            any governmental, quasi-governmental, or utility authority with
            jurisdiction over the Premises;

      (iii) is not of a first-class character, quality or appearance, consistent
            with the overall character, quality and appearance of the Building;

  E.  Cost Estimates. Landlord shall obtain a cost estimate from its contractor
      based on the approved preliminary plans and specifications and Approved
      Working Drawings, respectively, and Tenant shall have three (3) business
      days after the date of submission to Tenant of each cost estimate to
      approve or disapprove. A cost estimate shall be deemed approved if Tenant
      fails to disapprove it within the three (3) business day period. If Tenant
      disapproves a cost estimate, Tenant shall have five (5) business days
      after the date of disapproval to reduce the cost estimate by agreeing to
      modifications to the plans and specifications or to the Approved Working
      Drawings, which modifications shall be subject to the prior written
      approval of Landlord. If Tenant disapproves a cost estimate but fails to
      approve modifications which will reduce the cost estimate within the five
      (5) business day period, Landlord may either terminate this Agreement and
      the Lease or proceed with construction on the basis of the last cost
      estimate submitted to Tenant.

  F.  Tenant's Approval. Whenever Tenant's approval is required pursuant to the
      terms of this Agreement, the approval shall not be unreasonably withheld
      or delayed. Tenant's approvals or disapprovals shall be in writing.

  G.  Termination. If this Agreement and the Lease are terminated by Landlord
      pursuant to any of the provisions of this Agreement, the parties' rights
      and obligations hereunder shall be discharged; provided, however, Tenant
      shall pay Landlord, within ten (10) days after the date of Tenant's
      receipt of a statement for the same, the costs incurred by Landlord
      through the date of termination in connection with the preparation of any
      plans, drawings, and specifications and all costs incurred by Landlord in
      applying for any governmental approvals, including a building permit,
      required for construction of the Tenant Improvements.

2. CONSTRUCTION OF TENANT IMPROVEMENTS.

  A.  Construction by Landlord. Landlord shall cause construction of the Tenant
      Improvements to be completed in a good and workmanlike manner with the
      costs to be expended by Landlord not to exceed the amount of Eighty-Seven
      Thousand Three Hundred Thirty-Six and 00/100 Dollars ($87,336.00) (the
      "Base Allowance"); provided, however, until such time as Tenant either
      provides evidence of the Additional Capital (as defined in Section 26.1 of
      the Lease) or deposits with Landlord the Additional Security Deposit (as
      defined in Section 26.1 of the Lease), Landlord shall have no obligation,
      notwithstanding any thing to the contrary contained herein, to expend more
      than Forty Six Thousand Two Hundred Sixty and 00/100 Dollars ($46,260.00)
      (the "Reduce Base Allowance") for the Tenant Improvements. Upon delivery
      of evidence of the Additional Capital or deposit of the Additional
      Security Deposit in accordance with Section 26.1, Landlord shall agree to
      expend the balance of the Base Allowance for the Tenant Improvements. If
      the entire Base Allowance (or the Reduced Base Allowance, as applicable)
      is not expended by Landlord, then such unused portion shall be treated as
      a credit against the Tenant's next monthly payment(s) of Base Rent.

  B.  Tenant Improvements Cost. The Tenant Improvements cost ("Tenant
      Improvements Cost") to be paid by Landlord, subject to the provisions of
      Section 3 of this Agreement, shall include, but not be limited to:

      (i)  All costs of preliminary and final architectural and engineering
           plans, drawings and specifications for the Tenant Improvements, and
           engineering costs associated with completion of the State of
           California energy utilization calculations under Title 24
           legislation;

      (ii) All costs of obtaining building permits and other necessary
           authorizations from the applicable governmental authority (e.g., the
           City in which the Building is located);
<PAGE>

     (iii)  All costs of interior design and finish schedule plans, drawings and
            specifications including as-built drawings;

     (iv)   All direct and indirect costs of procuring and installing Tenant
            Improvements in the Premises, including the contractor's fee for
            profit, contractor's fee for overhead, the cost of all of
            contractor's on-site supervisory and administrative staff, office,
            equipment and temporary services provided in connection with
            construction of the Tenant Improvements;

     (v)    All fees payable to Landlord's architect, engineer or space planner
            if they are required to redesign any portion of the Tenant
            Improvements following Tenant's approval of the preliminary or
            working drawings;

     (vi)   Sewer connection fees, if any;

     (vii)  The fee charged by any construction cost consultant and/or
            construction manager employed in connection with the Tenant
            Improvement; and

     (viii) Fire and Builder's All-Risk insurance and public liability
            insurance premiums and fees.

3. EXCESS TENANT IMPROVEMENTS COST.  If the total Tenant Improvements Cost is
   more than the Base Allowance or the Reduced base Allowance, as applicable,
   then, the excess Tenant Improvements Cost shall be paid by Tenant to
   Landlord, in cash, within ten (10) days after receipt of a statement from
   Landlord, as additional rent.

4. CHANGE REQUESTS.

   A. No changes to the Approved Working Drawings requested by Tenant shall be
      made without Landlord's prior approval, which approval shall not be
      unreasonably withheld; provided, however, that no change request shall
      affect the structure of the Building. Any changes to the Approved Working
      Drawings shall be in writing and shall be signed by both Landlord and
      Tenant prior to the change being made. Tenant shall not instruct or direct
      Contractor workmen, subcontractors, material suppliers, or others
      performing the Tenant Improvements construction. Tenant shall direct all
      inquiries and requests relating to the construction work to Landlord or
      Landlord's designated agent. Tenant shall be responsible for any added
      costs or delays resulting from Tenant's actions which are contrary to this
      Paragraph 4.

   B. (i) Tenant shall pay Landlord in cash, within thirty (30) days after
      receipt of an itemized written bill from Landlord, any additional costs
      for changes requested by Tenant, including, without limitation,
      architectural fees and increases in construction costs caused by the
      delay; (ii) a change request shall constitute an agreement by Tenant to
      any reasonable delay in substantial completion caused by reviewing,
      processing and implementing the change; and (iii) the Lease, at Landlord's
      option, shall commence on the date it would have otherwise commenced but
      for any such delays.

   C. As soon as reasonably possible after receipt of a written change request
      from Tenant, Landlord shall notify Tenant of Landlord's approval or
      disapproval of the request; and, if the request is approved, of an
      estimated increase or decrease in costs and an estimate of the effect the
      change shall have on the projected date for substantial completion of the
      Tenant Improvements.

   D. Landlord shall have the authority, without the consent of Tenant, to order
      minor changes in the Tenant Improvements not involving an increase in cost
      to Tenant or a delay in the Commencement Date and not inconsistent with
      the intent of the Approved Working Drawings.

5. COOPERATION. Landlord and Tenant shall cooperate and diligently assist the
   architect, engineer or space planner in completing the Approved Working
   Drawings and specifications and the Contractor in completing construction of
   the Tenant Improvements.

6. CONDITION OF TENANT IMPROVEMENTS. Within seven (7) days after the
   Commencement Date, Tenant shall "walk-through" the Premises with Landlord and
   they shall complete a punch-list of items needing additional work by
   Landlord. Other than the items specified in the punch-list, by taking
   possession of the Premises, Tenant shall be deemed to have accepted the
   Premises and the Building in good, clean and completed condition and repair,
   subject to all applicable laws, codes and ordinances.
<PAGE>

   The punch-list shall not include any damage to the Premises or the Building
   caused by Tenant's move-in, which damage shall be promptly repaired or
   corrected by Tenant at its sole expense. If Tenant fails to complete a punch-
   list with Landlord's cooperation within the seven (7) day period specified
   above, it shall be deemed that there are no items needing additional work or
   repair. Contractor shall complete all reasonable punch-list items within
   thirty (30) days after the walk-through inspection or as soon as practicable
   thereafter and upon notification of completion of the punch-list items,
   Tenant shall approve or state its reasons for disapproval of the completed
   items in writing to Landlord within seven (7) days or such items shall be
   deemed approved by Tenant.

7. TENANT DELAYS. If the date of delivery of the Premises to Tenant by Landlord
   is delayed beyond the date anticipated by Landlord, and if the cause of the
   delay in the delivery of the Premises is attributable to Tenant, then the
   date of delivery of the Premises for purposes of calculating the Commencement
   Date and the commencement of Rent shall be the date the delivery of the
   Premises would have occurred but for such delay. Payments for any partial
   month shall be prorated on the basis of a thirty (30) day month. Delays
   attributable to Tenant shall include those caused by:

   A.  Tenant's failure to furnish information to Landlord for the preparation
       of plans and drawings for the Tenant Improvements in accordance with this
       Exhibit C;

   B.  Tenant's request for special materials, finishes or installations which
       are not readily available;

   C.  Tenant's failure to reasonably approve plans and working drawings in
       accordance with this Exhibit C;

   D.  Tenant's change requests pursuant to this Exhibit C that result in
       delays;

   E.  Tenant's failure to approve cost estimates if any approvals are required
       pursuant to this Exhibit C; and

   F.  Interference with Landlord's work caused by Tenant or by Tenant's agents.

8. TENANT IMPROVEMENTS COST AND RENT ADJUSTMENT STATEMENT. Within one hundred
   twenty (120) days after the Commencement Date, Landlord shall provide Tenant
   with a statement of the Tenant Improvements Cost. The statement shall include
   the balance due Landlord, if any (which shall be paid within ten (10) days as
   additional rent).

                       LANDLORD'S CONSENT AND AGREEMENT
                                  (Sublease)

     This Landlord's Consent and Agreement (the "Consent") is attached to that
certain Sublease (the "Sublease"), dated July 22, 1999 (the "Effective Date"),
between Burnham Pacific Operating Partnership, L.P., a Delaware limited
partnership ("Sublessor") and HealthCentral.com, Inc., a California corporation
("Sublessee"). Terms used in this Consent shall have the meaning set forth in
the Sublease.

     The undersigned, Christie Avenue Partners - JS, a California limited
partnership ("Landlord"), under the lease referred to as the "Lease" in the
Sublease hereby consents to the subletting described in the Sublease upon the
following express terms and conditions. Terms used in this Consent shall have
the meaning set forth in the Sublease and the Lease.

     1. The Sublease is subject and subordinate to the Lease and to all of the
terms, covenants, conditions, provisions and agreements set forth in the Lease.
The Sublease shall automatically terminate on the termination of the Lease.

     2. The Sublessee shall perform faithfully and be bound by all of the terms,
covenants, conditions, provisions and agreements of the Lease, for the period of
such subletting and to the extent of the Subleased Premises.

     3. Neither such subletting nor this Consent shall:

          (a) release or discharge Sublessor from any liability, whether past,
present or future, under the Lease;

          (b) operate as a consent or approval by Landlord to or of any of the
terms, covenants, conditions, provisions or agreements of the Sublease and
Landlord shall not be bound thereby;

          (c) be construed to modify, waive or affect any of the terms,
covenants, conditions, provisions or agreements of the Lease or to waive any
breach thereof, or any of Landlord's rights as Landlord thereunder; or to
enlarge or increase Landlord's obligations as Landlord thereunder, or

          (d) be construed as a consent by Landlord to any further subletting
either by Sublessor or by Sublessee or to any assignment by Sublessor of the
Lease or assignment by Sublessee of the Sublease, whether or not the Sublease
purports to permit the same and, without limiting the generality of the
foregoing, both Sublessor and Sublessee agree that the Sublessee has no right
whatsoever to assign, mortgage or encumber the Sublease nor to sublet any
portion of the Subleased Premises or permit any portion of the Subleased
Premises to be used or occupied by any other party.

     4. Sublessor shall not be released from any liability under the Lease
because of Landlord's failure to give notice of default under or in respect of
the terms, covenants, conditions, provisions or agreements of the Lease.

     5. In the event of Sublessor's default under the provisions of the Lease,
the rent due from the Sublessee under the Sublease shall be deemed assigned to
Landlord and Landlord shall have the right, upon such default, at any time at
Landlord's option, to give notice of such assignment to the Sublessee, and
Sublessee shall thereafter pay all rent under the Sublease directly to Landlord.
Landlord shall credit Sublessor with any rent received by Landlord under such
assignment but the acceptance of any payment on account of rent from the
Sublessee as the result of any such default shall in no manner whatsoever be
deemed an attornment by the Sublessee to Landlord, or serve to release Sublessor
from liability under the terms, covenants, conditions, provisions or agreements
under the Lease.

     6. Both Sublessor and Sublessee shall be and continue to be liable for the
payment of all bills rendered by Landlord for charges incurred by Landlord for
services and materials supplied to the Subleased Premises.
<PAGE>

     7.  The term of the Sublease shall expire and come to an end on its natural
expiration date or any premature termination date thereof or concurrently with
any premature termination of the Lease (whether by consent or other right, now
or hereafter agreed to by Landlord or Sublessor), or by operation of law or at
Landlord's option in the event of default by Sublessor.

     8.  This Consent is not assignable, nor shall this Consent be a consent to
any amendment, modification, extension or renewal of the Sublease, without
Landlord's prior written consent.

     9.  Sublessor and Sublessee covenant and agree that, under no circumstances
shall Landlord be liable for any brokerage commission or other charge or expense
in connection with the Sublease, and Sublessor and Sublessee agree to indemnify
Landlord against same and against any cost or expense (including but not limited
to counsel fees) incurred by Landlord in resisting any claim for any such
brokerage commission.

     10. Sublessor and Sublessee understand and acknowledge that Landlord's
consent hereto is not a consent to any improvement or alteration work being
performed in Subleased Premises, that Landlord's consent must be separately
sought for such work.

     11. Notwithstanding any provision of the Sublease or this Consent to the
contrary, Sublessee agrees that Landlord shall not be (i) liable for any act or
omission of Sublessor under the Sublease, (ii) liable for any act or omission by
any party which occurred prior to the termination date, (iii) subject to any
offsets or defenses which Sublessee may have against Sublessor, (iv) bound by
any payment of rent or other sums made by Sublessee for any advance period under
the Sublease, (v) bound by any security deposits which Sublessee might have paid
to Sublessor or any other party, or (v) bound by any amendment or modification
of the Sublease made without Landlord's prior written consent, which may be
withheld in the sole and absolute discretion of Landlord.

     12. This Consent shall for all purposes be construed in accordance with and
governed by the laws of the State of California.

     13. This Consent shall not be effective until executed by all the parties
hereto.

     14. If any one or more of the provisions contained in this Consent shall be
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained in this Consent shall not
in any way be affected or impaired thereby.

     15. Landlord shall be named as an additional insured under all insurance
required to be carried by Sublessee pursuant to Section 10 of the Sublease, and
Sublessor shall furnish Landlord with a certificate of insurance within thirty
(30) days of the commencement of the term of the Sublease.

     The execution of a copy of this Consent by Sublessor and by the Sublessee
shall indicate your joint and several confirmation of the foregoing conditions
and of your agreement to be bound thereby and shall constitute Sublessee's
acknowledgment that it has received a copy of the Lease.

     IN WITNESS WHEREOF, the parties hereto have executed this Consent as of the
day and year of the Sublease.

Master Lease.

5.   TERM.

Date"), or when Lessor consents to this Sublease (if such consent is required

          month, the rent for the partial months shall be prorated on a per diem
          basis. Additional provisions: from and after January 1, 2002, the

          Lessor all or a portion of the expenses of operating the building
          and/or project of which the Premises are a part ("Operating Costs"),
          including but not limited to taxes, utilities, or insurance, then

          percent (100%) of the amounts payable by Sublessor for Operating Costs
          incurred during the Term. Such additional rent shall be payable as and

          xxxxx provides for the payment by Sublessor of Operating Costs on the
          basis of an estimation thereof, then as and when adjustments between
          estimated and actual Operating Costs are made under the xxxxxx Lease,
          the obligations of Sublessor and Sublessee hereunder shall be adjusted
          in a like manner and if any such adjustment shall occur after the
          expiration of earlier termination of the Term, then the obligations of
          the Sublessor and Sublessee under the Subsection 6.2 shall survive
          such expiration or termination. Sublessor shall, upon request by
          Sublessee, furnish Sublessee with copies of all statements submitted
          by Lessor of actual or estimated Operating Costs during the Term.

7.   SECURITY DEPOSIT.

     Sublessee shall deposit with Sublessor upon execution of this Sublease the
     sum of Twelve Thousand Five Hundred Eighteen and no/100 Dollars
     ($12,518.00) as security for Sublessor's faithful performance of
     Sublessee's obligations hereunder ("Security Deposit"). If Sublessee fails
     to pay rent or other charges when due under this Sublease, or fails to
     perform any of its other obligations hereunder, Sublessor may use or apply
     all or any portion of the Security Deposit, for the payment of any rent or
     other amount then due hereunder and unpaid, for the payment of any other
     sum for which Sublessor may become obligated by reason of Sublessee's
     default or breach, or for any loss or damage sustained by Sublessor as a
     result of Sublessee's default or breach. If Sublessor so uses any portion
     of the Security Deposit Sublessee shall, within ten (10) days after written
     demand by sublessee, restore the security deposit to the full amount
     originally deposited, and Sublessee's failure to do so shall constitute a
     default under the Sublease, Sublessor shall not be required to keep the
     Security Deposit separate from its general accounts, and shall have no
     obligation or liability for payment of interest on the Security Deposit. In
     the event Sublessor assigns its interest in this Sublease, Sublessor shall
     deliver to its assignee so much of the Security Deposit as is then held by
     Sublessor. Within ten (10) days after the Term has expired, or Sublessee
     has vacated the Premises, or any final adjustment pursuant to Subsection
     6.2 hereof has been made, whichever shall last occur, and provided
     Sublessee is not then in default of any of its obligations hereunder, the
     Security Deposit, or so much thereof as had not theretofore been applied by
     Sublessor, shall be returned to Sublessee.

8.   USE OF PREMISES.

     The Premises shall be used and occupied only for general office use, and
     for no other use or purposes.

9.   ASSIGNMENT AND SUBLETTING.

     Sublessee shall not assign this Sublease or further sublet all or any part
     of the Premises without the prior written consent of Sublessor (and the
     consent of Lessor, if such is required under the terms of the Master
     Lease).

10.  OTHER PROVISIONS OF SUBLEASE.

     All applicable terms and conditions of the Master Lease are incorporated
     into and made a part of this Sublease as if Sublessor were the lessor
     thereunder Sublessee the lessee thereunder, and the Premises the Master
     Premises, except for the following: Section 3.2.

     Sublessee assumes and agrees to perform the Lessee's obligations under the
     Master Lease during the Term to the extent that such obligations are
     applicable to the Premises, except that the obligation to pay rent to
     Lessor under the Maser Lease shall be considered performed by Sublessee to
     the extent and in the amount rent is paid to Sublessor in accordance with
     Section 6 of the Sublease. Sublessee shall not commit or suffer any act or
     omission that will violate any of the provisions of the Master Lease.
     Sublessor shall exercise due diligence in attempting to cause Lessor to
     perform the obligations under the Master Lease for the benefit of the
     Sublessee. If the Master Lease terminates, this Sublease shall terminate
     and the parties shall be relieved of any further liability or obligation
     under this Sublease, provided, however, that the Master Lease terminates as
     a result of a default or breach by sublessor or Sublessee under the
     Sublease and/or the Master Lease, then the defaulting party shall be liable
     to the
<PAGE>

     nondefaulting party for the damage suffered as a result of such
     termination. Notwithstanding the foregoing, if the Master Lease gives
     Sublessor any right to terminate the Master Lease in the event of the
     partial or total damage, destruction, or condemnation of the Master
     Premises or the building or project of which the Master Premises are a
     part, the exercise of such right by Sublessor shall not constitute a
     default or breach hereunder.

11.  ATTORNEYS' FEES.

     If Sublessor, Sublessee, or Broker shall commence an action against the
     other arising out of or in connection with this Sublease, the prevailing
     party shall be entitled to recover its costs of suit and reasonable
     attorney's fees.

12.  AGENCY DISCLOSURE.

     real estate broker in connection with this transaction except CB COMMERCIAL
     REAL ESTATE GROUP, INC., who represents Sublessee and Colliers
     International, who represents Sublessor.

14.  NOTICES.

the business of the partnership or entity which constitutes Landlord as the same
are distinguished from the costs of operation of the Marketplace. Landlord
further agrees that since one of the purposes of the Operating Expenses
provisions is to allow Landlord to require Tenant to pay for the costs
attributable to its Premises, Landlord agrees that Landlord will not collect or
be entitled to collect Operating Expenses from all of its tenants in an amount
which is in excess of one hundred percent (100%) of the Operating Expenses
actually paid by Landlord in connection with the operation of the Marketplace.
Subject to the provisions of this definition, the determination of Operating
Expenses shall be made by Landlord in accordance with generally accepted
accounting principles and practices consistently applied. To reflect the fact
that the Building constitutes approximately 44.9% of the Marketplace, the term
"Operating Expenses" shall include the following: (i) 100% of Operating
Expenses, as defined above, paid or incurred with respect to the Building, (ii)
44.9% of Operating Expenses, as defined above, paid or incurred with respect to
the Marketplace in general, and (iii) fifty (50%) percent of the second floor
lobby expenses in the brick building.

     Real Estate Taxes: 44.9% of all taxes, assessments and charges now or
hereafter levied or assessed upon, or with respect to, the Marketplace or any
portion thereof, or any personal property of Landlord used in the operation
thereof or located therein, or Landlord's interest in the Marketplace or such
personal property, by any federal, state or local entity, including: (i) all
real property
<PAGE>

taxes and general and special assessments; (ii) charges, fees or assessments for
transit, housing, day care, open space, art, police, fire or other governmental
services or benefits to the Marketplace; (iii) service payments in lieu of
taxes; (iv) any tax, fee or excise on the use or occupancy of any part of the
Marketplace, or on rent for space in the Marketplace; (v) any other tax, fee or
excise, however described, that may be levied or assessed as a substitute for,
or as an addition to, in whole or in part, any other Real Estate Taxes, and (vi)
reasonable fees and expenses, including those of consultants or attorneys,
incurred in connection with proceedings to contest, determine or reduce Real
Estate Taxes. Real Estate Taxes do not include: (A) franchise, transfer,
inheritance or capital stock taxes, or income taxes measured by the net income
of Landlord from all sources, unless any such taxes are levied or assessed
against Landlord as a substitute for, in whole or in part, any Real Estate Tax;
(B) Impositions and all similar amounts payable by tenants of the Marketplace
under their leases; and (C) penalties, fines, interest or charges due for late
payments of Real Estate Taxes by Landlord. If any Real Estate Taxes or payable,
or may at the option of the taxpayer be paid, in installments, such Real Estate
Taxes shall, together with any interest that would otherwise be payable with
such installments, be deemed to have been paid in installments, amortized over
the maximum time period allowed by applicable law.

     Rent: Base Rent, Impositions, Operating Expenses, Real Estate Taxes and all
other additional charges and amounts payable by Tenant in accordance with this
Lease.

     Rentable Area: As to a floor leased entirely by Tenant, all areas within
exterior permanent Building walls measured to the inside glass surface of outer
Building walls, including restrooms, janitor, telephone and electrical closets,
mechanical areas, and columns and projections necessary to the Building, but
excluding public stairs, elevator shafts and pipe shafts. As to a floor only a
portion of which is leased by Tenant, the aggregate of (i) the Leased Area (as
defined below) of the portion of the floor occupied by Tenant, plus (ii) the
result obtained by multiplying (1) the area of the Common Area (as defined
below) on such floor by (2) a fraction whose numerator is the Leased Area of
Tenant's portion of the floor and whose denominator is the Leased Area of all
tenant space on such floor, plus (iii) in the event that Landlord must enlarge
or alter in any way, shape or fashion the Common Area to accommodate Tenant's
Leased Area, the total additional Common Area space. For purposes hereof,
"Leased Area" shall mean all floor area in a tenant space, measured to the
inside glass surface of exterior Building walls, to the center of corridors and
other permanent partitions, and to the center of portions that separate tenant
space from adjoining tenant spaces, without deduction for columns and
projections necessary to the Building; and "Common Area" shall mean the total
area on a floor consisting of restrooms, janitor, telephone and electrical
closets, mechanical areas and public corridors providing access to tenant space
on such floor, but excluding public stairs, elevator shafts and pipe shafts.

     Tenant's Percentage Share: The percentage figure specified in the Basic
Lease Information. Landlord and Tenant acknowledge that Tenant's Percentage
Share has been obtained by (i) dividing the Rentable Area of the Premises, as
specified in the Basic Lease Information by the total Rentable Area of the
Building, and multiplying such quotient by one hundred (100). In the event
Tenant's Percentage Share is changed during a calendar year by reason of a
change in the Rentable Area of the Premises or a change in the total Rentable
Area of the Building, Tenant's Percentage Share shall thereafter mean the result
obtained by dividing the then Rentable Area of the Premises by the then total
Rentable Area of the Building and multiplying such quotient by one hundred
(100). For the purposes of determining Tenant's Percentage Share of Impositions,
Operating Expenses and Real Estate Taxes, Tenant's Percentage Share shall be
determined on the basis of the number of days during such calendar year at each
such Percentage Share.

     Tenant's Marketplace Proportionate Share: That percentage determined by
dividing the Rentable Area of the Premises by the total Rentable Area of the
Marketplace. Landlord and Tenant agree that Tenant's Marketplace Proportionate
Share is 4.01% (which equals the quotient expressed as a percentage of 8815
divided by 219,925.

     Term: The period from the Commencement Date to the Expiration Date.

     Wattage Allowance: The product obtained by multiplying the Rentable Area of
the Premises by 4.5 watts. "Lighting Wattage Allowance" means thirty-three
percent (33%) of the Wattage Allowance.

     1.2. Effect of Certain Defined Terms. The parties acknowledge that the
Rentable Area of the Premises and the Building have been finally determined by
the parties as part of this Lease for all purposes, including the calculation of
Tenant's Percentage Share and will not, except as otherwise provided in this
Lease, be changed.

     2.   Lease of Premises.
<PAGE>

          2.1. Premises.  Landlord leases to Tenant and Tenant leases from
Landlord the Premises, together with the non-exclusive right to use, in common
with others, the lobbies, entrances, stairs, elevators, plazas, pedestrian
walkways, restrooms, and other public portions of the Building, all subject to
the terms, covenants and conditions set forth in this Lease. All the windows and
exterior walls of the Premises, the terraces adjacent to the Premises, if any,
and any space in the Premises used for shafts, columns, projections, stacks,
pipes, conduits, ducts, electric utilities, sinks or other Building facilities,
and the use thereof and access thereto through the Premises for the purposes of
management, operation, maintenance and repairs, are reserved to Landlord.

     3.   Term: Condition and Acceptance of Premises.

          3.1  Commencement and Acceptance.  Except as hereinafter provided, and
unless sooner terminated pursuant to the provisions of this Lease, the Term of
this Lease shall commence on the Commencement Date and end on the Expiration
Date. Landlord shall deliver the Premises to Tenant on the Commencement Date in
their "as-is" condition without obligation to make any alterations or
improvements to the Premises. If Landlord, for any reason whatsoever, cannot
deliver the Premises to Tenant in the condition specified herein by the
Commencement Date, this Lease shall not be void or voidable, and Landlord shall
not be in default or liable to Tenant for any loss or damage resulting
therefrom, but, subject to the provisions of Section 7 of the Work Letter, in
such event Base Rent shall be waived for the period between the Commencement
Date and the actual date that Landlord delivers the Premises to Tenant. No delay
in delivery of the Premises for any reason whatsoever shall operate to extend
the Expiration Date or the Term. In the event that the Premises are delivered to
Tenant on any date other than the Commencement Date set forth in the Basic Lease
Information of this Lease, Landlord and Tenant shall execute a Confirmation of
Lease Term in the form as set forth in Exhibit E attached to this Lease.
Tenant's occupancy of all or any portion of the Premises shall constitute
Tenant's acceptance of the Premises in the condition called for by this Lease.

          3.2  Option to Extend.

               3.2.1. Exercise of Option to Extend Term. If no "Suspension
Condition" (as hereinafter defined) exists at the time of Tenant's exercise of
its option to extend the initial Term or at the commencement of the Extended
Term, as the case may be, Tenant shall have one (1) option ("Extension Option")
to extend the initial Term for one (1) additional period of five (5) years
("Extended Term"). To exercise Tenant's option with respect to the Extended
Term, Tenant shall give notice to Landlord not less than nine (9) months prior
to the expiration of the initial Term ("Election Notice"). A "Suspension
Condition" shall mean the existence of any event or condition of material
default with respect to any obligation under this Lease where notice of default
has been given by Landlord and such default has not been cured by Tenant within
the applicable notice and cure period specified in this Lease. Tenant's exercise
of the Extension Option shall in no way result in, or constitute, a waiver by
Landlord of any default by Tenant under this Lease.

               3.2.2. Fair Market Rent. If Tenant properly and timely exercises
Tenant's option to extend pursuant to Section 3.2.1 above, such extension shall
be upon all of the same terms, covenants and conditions of this Lease, provided,
however, that the Base Rent applicable to the Premises for the Extended Term
shall be the greater of: (i) the Base Rent as of the last month of the initial
Term, or (ii) one hundred percent (100%) of the "Fair Market Rent" for space
comparable to the Premises as of the commencement of the Extended Term. "Fair
Market Rent" shall mean the annual rental being charged for space comparable to
the Premises in comparable office buildings in the Berkeley/Emeryville area,
taking into account location, parking, condition and improvements to the space.
Neither Landlord nor Tenant shall pay any leasing commissions or consulting fees
payable in connection with such extensions, unless such leasing commissions or
consulting fees arise solely out of a contractual relationship between either
Tenant or Landlord and a broker or consultant, in which event such fees shall be
the sole responsibility of the contracting party. All other terms and conditions
of the Lease, which may be amended from time to time by the parties in
accordance with the provisions of the Lease, shall remain in full force and
effect and shall apply during the Extended Term, except that there shall be no
further option to extend, there shall be no further rent concessions, there
shall be no tenant improvements allowance and similar provisions.

               3.2.3 Determination of Rent. Within thirty (30) days after the
date of the Election Notice, Landlord and Tenant shall negotiate in good faith
in an attempt to determine Fair Market Rent for the Extended Term. If they are
unable to agree within said thirty (30) day period, then the Fair Market Rent
shall be determined as provided in Section 3.2.4 below.

               3.2.4 Appraisal. If it becomes necessary to determine the Fair
Market Rent for the Premises by appraisal, the real estate appraiser(s)
indicated in this Section 3.2.4, each of whom shall be members of the Appraisal
Institute and each of whom have at least five (5) years experience appraising
office space located in the vicinity of the Premises, shall be appointed and
shall not in accordance with the following procedures:
<PAGE>

               (i) If the parties are unable to agree on the Fair Market Rent
within the allowed time, either party may demand an appraisal by giving written
notice to the other party; which demand to be effective must state the name,
address and qualifications of an appraiser selected by the party demanding the
appraisal ("Notifying Party"). Within twenty (20) days following the Notifying
Party's appraisal demand, the other party ("Non-Notifying Party") shall either
approve the appraiser selected by the Notifying Party or select a second
properly qualified appraiser by giving written notice of the name, address and
qualification of said appraiser to the Notifying Party. If the Non-Notifying
Party fails to select an appraiser within the twenty (20) day period, the
appraiser selected by the Notifying Party shall be deemed selected by both
parties and no other appraiser shall be selected. If two (2) appraisers are
selected, they shall select a third approximately qualified appraiser. If the
two (2) appraisers fail to select a third qualified appraiser, the third
appraiser shall be appointed by the then presiding judge of the county where the
Premises are located upon application by either party.

               (ii) If only one appraiser is selected, that appraiser shall
notify the parties in simple letter form of its determination of the Fair Market
Rent for the Premises within fifteen (15) days following his or her selection,
which appraisal shall be conclusively determinative and binding on the parties
as the appraised Fair Market Rent.

               (iii) If multiple appraisers are selected, the appraisers shall
meet not later than ten (10) days following the selection of the last appraiser.
At such meeting, the appraisers shall attempt to determine the Fair Market Rent
for the Premises as of the commencement date of the Extended Term in question by
the agreement of at least two (2) of the appraisers.

               (iv) If two (2) or more of the appraisers agree on the Fair
Market Rent for the Premises at the initial meeting, such agreement shall be
determinative and binding upon the parties hereto and the agreeing appraisers
shall forthwith notify both Landlord and Tenant of the amount set by such
agreement. If multiple appraisers are selected and two (2) appraisers are unable
to agree on the Fair Market Rent for the Premises, each appraiser shall submit
to Landlord and Tenant his or her respective independent appraisal of the Fair
Market Rent for the Premises, in simple letter form, within twenty (20) days
following appointment of the final appraiser. The parties shall then determine
the Fair Market Rent for the Premises by averaging the appraisals; provided that
any high or low appraisal, differing from the middle appraisal by more than ten
percent (10%) of the middle appraisal, shall be disregarded in calculating the
average.

               (v) If only one (1) appraisal is selected, then each party shall
pay one-half (1/2) of the fees and expenses of that appraiser. If three (3)
appraisers are selected, each party shall bear the fees and expenses of the
appraiser it selects and one-half (1/2) of the fees and expenses of the third
appraiser.

               (vi) Notwithstanding anything to the contrary contained in this
Section 3.2, in no event shall the Base Rent for the Exercised Term be less than
the Base Rent payable by Tenant during the month immediately preceding the
Extended Term.

        3.2.5. Restriction on Assignment. The Extension Option shall be personal
to Tenant and any entity controlled by or under common control of Burnham
Pacific Properties, Inc., a Maryland corporation, shall not be assignable or
transferable (except in connection with an Exempt Transfer or an Exempt
Sublease), and shall terminate upon any assignment or sublease of all or any
portion of the Premises greater than ten percent (10%) of the Rentable Area of
the Premises (except in connection with an Exempt Transfer or an Exempt
Sublease).

        3.2.6. Amendment to Lease. Immediately after the Fair Market Rent has
been determined, the parties shall enter into an amendment to this Lease setting
forth the Base Rent for the Extended Term and shall also state the new
Expiration Date of the Term of the Lease.

     4. Rent.

        4.1. Obligation to Pay Base Rent. Tenant shall pay Base Rent to
Landlord, in advance, in equal monthly installments, commencing on or before the
Commencement Date, and thereafter on or before the first day of each calendar
month during the Term. If the Commencement Date and/or Expiration Date is other
than the first day of a calendar month, the installment of Base Rent for the
first and/or last fractional month of the Term shall be prorated on a daily
basis. On full execution of this Lease, Tenant shall pay to Landlord the first
month's Base Rent.
<PAGE>

          4.2. Manner of Rent Payment. All Rent shall be paid by Tenant without
notice, demand, abatement, deduction or offset, in lawful money of the United
States of America, payable to Landlord, at Landlord's Address as set forth in
the Basic Lease information, or to such other person or at such other place as
Landlord may from time to time designate by notice to Tenant.

          4.3. Additional Rent. All Rent not characterized as Base Rent or
Impositions, Operating Expenses and Real Estate Taxes shall constitute
additional rent, and if payable to Landlord shall, unless otherwise specified in
this Lease, be due and payable fifteen (15) days after Tenant's receipt of
Landlord's invoice therefor.

          4.4. Late Payment of Rent; Interest. Tenant acknowledges that late
payment by Tenant of any Rent will cause Landlord to incur administrative costs
not contemplated by this Lease, the exact amount of which are extremely
difficult and impracticable to ascertain based on the facts and circumstances
pertaining as of the Lease Date. Accordingly, if any Rent is not paid by Tenant
within five (5) days after Landlord's delivery of notice of payment due, Tenant
shall pay to Landlord, with such Rent, a late charge equal to five percent (5%)
of such Rent; provided, however, that if Tenant is obligated to pay two (2) late
charges in any calendar year, then during the remainder of the calendar year
Tenant shall be obligated to pay a late charge equal to eight percent (8%) of
such unpaid Rent if such Rent is not paid on or before the due date. Any Rent,
other than late charges, due Landlord under this Lease, if not paid when due,
shall also bear interest from the date due until paid, at the rate of ten
percent (10%) per annum or, if a higher rate is legally permissible, at the
highest rate legally permitted. The parties acknowledge that such late charge
and interest represent a fair and reasonable estimate of the administrative
costs and loss of use of funds Landlord will incur by reason of a late Rent
payment by Tenant, but Landlord's acceptance of such late charge and/or interest
shall not constitute a waiver of Tenant's default with respect to such Rent or
prevent Landlord from exercising any other rights and remedies provided under
this Lease, at law or in equity.

     5.   Calculation and Payments of Rent. During each full or partial calendar
year of the Term, Tenant shall pay to Landlord Impositions, Operating Expenses
and Real Estate Taxes in accordance with the following procedures:

          5.1. Payment of Estimated Rent. At the Commencement Date and December
of each subsequent calendar year, or as soon thereafter as practicable, Landlord
shall given Tenant notice of its estimate of Impositions, Operating Expenses and
Real Estate Taxes due for the next ensuing calendar year. On or before the first
day of each month during such next ensuing calendar year, Tenant shall pay to
Landlord in advance, in addition to Base Rent, one-twelfth (1/12th) of such
estimated Impositions, Operating Expenses and Real Estate Taxes. In the event
such notice is given after December 31st of any year during the Term, (i) Tenant
shall continue to pay Impositions, Operating Expenses and Real Estate Taxes on
the basis of the prior calendar year's estimate until the month after such
notice is given, (ii) subsequent payments by Tenant shall be based of the
estimate of Impositions, Operating Expenses and Real Estate Taxes set forth in
Landlord's notice, and (iii) with the first monthly payment of Impositions,
Operating Expenses and Real Estate Taxes based on the estimate set forth in
Landlord's notice, Tenant shall also pay the difference, if any, between the
amount previously paid for such calendar year and the amount which Tenant would
have paid through the month in which such notice is given, based on Landlord's
noticed estimate or, in the alternative, if such amount previously paid by
Tenant for such calendar year through the month in which such notice is given
exceeds the amount which Tenant would have paid through such month based on
Landlord's noticed estimate. Landlord shall credit such excess amount against
the next monthly payments of Impositions, Operating Expenses and Real Estate
Taxes due from Tenant. If at any time Landlord reasonably determines that the
Impositions, Operating Expenses and Real Estate Taxes for the current calendar
year will vary from Landlord's estimate by more than five percent (5%), Landlord
may, by notice to Tenant, revise its estimate for such calendar year, and
subsequent payments by Tenant for such calendar year shall be based upon such
revised estimate.

          5.2. Statement and Adjustment. Within one hundred twenty (120) days
after the close of each calendar year, or as soon thereafter as practicable,
Landlord shall deliver to Tenant a statement of the actual Rent for such
calendar year, accompanied by a statement prepared by Landlord showing in
reasonable detail the Operating Expenses, Impositions and the Real Estate Taxes
comprising the actual Rent. If Landlord's statement shows that Tenant owes an
amount less than the payments previously made by Tenant for such calendar year,
Landlord shall credit the difference first against any sums then owed by Tenant
to Landlord and then against the next payment or payments of Rent due Landlord,
except that if a credit amount is due Tenant after termination of this Lease,
Landlord shall pay to Tenant any excess remaining after Landlord credits such
amount against any sums owed by Tenant to Landlord. If Landlord's statement
shows that Tenant owes an amount more than the payments previously made by
Tenant for such calendar year, Tenant shall pay the difference to Landlord
within fifteen (15) days after delivery of the statement. Tenant shall have the
right to audit Landlord's calculation of Operating Expenses, subject to the
following limitations: (i) such audit shall be conducted no more than one time
per calendar year, (ii) Tenant shall pay all of Landlord's reasonable costs and
expenses (including a reasonable allocation of Landlord's internal overhead
costs) incurred in connection with facilitating and monitoring such audit, (iii)
such audit
<PAGE>

may not be conducted by a person or entity whose compensation is in any way
calculated based on the results of such audit, (iv) Landlord shall pay Tenant's
reasonable out-of-pocket cost (but not to exceed $3,000.00) of any such audit
undertaken by Tenant in accordance with the foregoing which is reasonably
approved by Landlord and which discloses an overstatement of Operating Expenses
of more than five percent (5%), and (v) if at the time of the performance of the
audit the Landlord under this lease is Teacher's, defined below, then Tenant
shall only have the right to examine Teacher's books which related to the
Operating Expenses in question.

          5.3. Proration for Partial Year. If this Lease terminates other than
on the last day of a calendar year (other than due to Tenant's default), the
amount of Rent for such fractional calendar year shall be prorated on a daily
basis. Upon such termination, Landlord may, at its option, calculate the
adjustment in Rent prior to the time specified in Section 5.2 above. Tenant's
obligation to pay Rent, as set forth in Paragraph 5.2, above, shall survive the
expiration or termination of this Lease. Upon expiration, either Landlord or
Tenant, as the case may be, shall make any payments to the other necessary to
refund or any excess or underpayment of Rent.

     6.   Impositions Payable by Tenant.  Tenant shall pay all Impositions prior
to delinquency. If billed directly to Tenant, Tenant shall pay such Impositions
and concurrently deliver to Landlord evidence of such payments. If any
Impositions are billed to Landlord or included in bills to Landlord for Real
Estate Taxes or other charges, then Tenant shall pay to Landlord all such
amounts within fifteen (15) days after delivery of Landlord's invoice therefor.
If applicable law prohibits Tenant from reimbursing Landlord for an Imposition,
but Landlord may lawfully increase the Base Rent to account for Landlord's
payment of such Imposition, the Base Rent payable to Landlord shall be increased
to net to Landlord the same return without reimbursement of such Imposition as
would have been received by Landlord with reimbursement of such Imposition.
Tenant's obligation to pay Impositions which have accrued and remain unpaid upon
the expiration or earlier termination of this Lease shall survive the expiration
of earlier termination of this Lease.

     7.   Use of Premises.

          7.1  Permitted Use. The Premises shall be used solely for the
Permitted Use and for no other use or purpose.

          7.2. No Violation of Level and Insurance Requirements. Tenant shall
not do or permit to be done, or bring or keep or permit to be brought or kept,
in or about the Premises, or any other portion of the Marketplace, anything
which (i) is prohibited by or will in any way conflict with any law, ordinance,
rule or regulation; (ii) would invalidate or be in conflict with the provisions
of any insurance policy carried by Landlord or Tenant on any portion of the
Marketplace or Premises, or any property therein; or (iii) would cause a
cancellation of any such insurance, increase the existing rate of or affect any
such Landlord's insurance, or subject Landlord to any liability or
responsibility for injury to any person or property. If Tenant does or permits
anything to be done which increases the cost of any of Landlord's insurance, or
which results in the need, in Landlord's reasonable judgment, for additional
insurance by Landlord or Tenant with respect to any portion of the Marketplace
or Premises, then Tenant shall reimburse Landlord, upon demand, for any such
additional costs or the costs of such additional insurance, and/or procure such
additional insurance at Tenant's sole cost and expense. Exercise by Landlord of
such right to acquire reimbursement of additional costs (including the costs of
procuring of additional insurance) shall not limit or preclude Landlord from
prohibiting Tenant's impermissible use of the Premises or from invoking any
other right or remedy available to Landlord under this Lease.

          7.3. Compliance with Legal Insurance and Life Safety Requirements.
Except as provided in clauses (i) through (iii) below, Tenant, at its cost and
expense, shall promptly comply with all laws, ordinances, rules, regulations,
orders and other governmental requirements, the requirements of any board of
five underwriters or other similar body, any directive or occupancy certificate
issued pursuant to any law by any public officer or officers, the provisions of
all recorded documents affecting any portion of the Marketplace and all life
safety programs, procedures and rules implemented or promulgated by Landlord
("Laws"). Tenant shall not, however, be required to comply with Laws requiring
Tenant to make structural changes to the Premises unless necessitated, in whole
or in part, by (i) Tenant's use or occupancy of, or business conducted in, the
Premises, (ii) any acts or omissions of Tenant, its employees, agents,
contractors, invitees or licensees, or (iii) Alterations (including any
alterations, additions or other improvements to the Premises made by or on
behalf of Tenant during the initial improvement of the Premises pursuant to the
Work Letter).

          7.4. No Nuisance. Tenant shall not (i) do or permit anything to be
done in or about the Premises, or any other portion of the Marketplace, which
would injure or annoy, or obstruct or interfere with the rights of, Landlord or
other occupants of the Marketplace, or others lawfully in or about the
Marketplace; (ii) use or allow the Premises to be used in any manner
inappropriate for a Class A office building, or for any improper or
objectionable purposes; or (iii) cause, maintain or permit any nuisance or waste
in, on or about the Premises, or any other portion of the Marketplace.

          7.5. Hazardous Substances. The term "hazardous substances" as used in
    the Lease, is defined as follows:

    Any element, compound, mixture, solution, particle or substance, which
    presents danger or potential danger of damage or injury to health, welfare
    or to the environment including, but not limited to: (i) those substances
    which are inherently or potentially radioactive, explosive, ignitable,
    corrosive, reactive, carcinogenic or toxic and (ii) those substances which
    have been recognized as dangerous or potentially dangerous to health,
    welfare or to the environment by any federal, municipal, state, county or
    other governmental or quasi-governmental authority and/or any department or
    agency thereof.

    Tenant represents and warrants to Landlord and agrees that all times during
the term of this Lease and any extensions or renewals thereof, Tenant shall:

          (i)   promptly comply at Tenant's sole cost and expense, with all
    laws, orders, rules, regulations, certificates of occupancy, or other
    requirements, as the same now exist or may hereafter be enacted, amended or
    promulgated, of any federal, municipal, state, county or other governmental
    or quasi-governmental authorities and/or any department or agency thereof
    relating to the manufacturing, processing, distribution, using, producing,
    treating, storing (above or below ground level), disposing or allowing to be
    present (the "Environmental Activity") of hazardous substances in or about
    the Premises (each, a "Law", and all of them, "Laws") by Tenant, its
    assignees and subtenants, and their respective agents, employees,
    contractors and invitees, and Tenant shall not allow the release or escape
    of any hazardous substances in or about the Building.

          (ii)  indemnify and hold Landlord, its agents and employees, harmless
    from any and all demands, claims, causes of action, penalties, liabilities,
    judgments, damages (including consequential damages) and expenses including,
    without limitation, court costs and reasonable attorneys' fees incurred by
    Landlord as a result of (a) Tenant's failure or delay in properly complying
    with any Law, or (b) any adverse effect which results from the Environmental
    Activity, whether Tenant or Tenant's subtenants or any of their respective
    agents, employees, contractors or invitees, with or without Tenant's consent
    has caused, either intentionally or unintentionally, such Environmental
    Activity. If any action or proceeding is brought against Landlord, its
    agents or employees by reason of any such claim, Tenant, upon notice from
    Landlord, will defend such claim at Tenant's expense with counsel reasonably
    satisfactory to Landlord. This indemnity obligation by Tenant of Landlord
    will survive the expiration or earlier termination of this Lease.

          (iii) promptly disclose to Landlord by delivering, in the manner
    prescribed for delivery of notice in this Lease, a copy of any forms,
    submissions, notices, reports, or other written documentation (each, a
    "Communication") relating to any Environmental Activity, whether any such
    Communication is delivered to Tenant or any of its subtenants or is
    requested of Tenant or any of its subtenants by any federal, municipal,
    state, county or other government or quasi-governmental authority and/or any
    department or agency thereof.

          (iv)  in the event there is a release of any hazardous substance as a
result of or in connection with any Environmental Activity by Tenant or any of
Tenant's subtenants or any of their respective agents, employees, contractors or
invitees, which must be remediated under any Law, Landlord shall perform the
necessary remediation; and Tenant shall reimburse Landlord for all costs thereby
incurred within fifteen (15) days after delivery of a written demand therefor
from Landlord (which shall be accompanied by reasonable substantiation of such
costs). In the alternative, Landlord shall have the right to require Tenant, at
its sole cost and expense, to perform the necessary remediation in accordance
with a detailed plan of remediation which shall have been approved in advance in
writing by Landlord. Landlord shall give notice to Tenant within thirty (30)
days after Landlord receives notice or obtains knowledge of the required
remediation. The rights and obligations of Landlord and Tenant set forth in this
subparagraph (iv) shall survive the expiration or earlier termination of this
Lease.

          (v)   notwithstanding any other provisions of this Lease, allow
Landlord, and any authorized representative of Landlord, access and the right to
enter and inspect the Premises for Environmental Activity, at any time deemed
reasonable by Landlord, without prior notice to Tenant.

          (vi)  Tenant shall not (either with or without negligence) cause or
permit the escape, disposal or release of any biologically or chemically active
or other hazardous substances, or materials. Tenant shall not allow the storage
or use of such substances or materials in any manner not sanctioned by law or by
the highest standards prevailing in the industry for the storage and use of such
substances or materials, nor allow to be brought into the Project any such
materials or substances except to use in the ordinary course of Tenant's
<PAGE>

business, and then only after written notice is given to Landlord of the
identity of such substances or materials. Without limitation, hazardous
substances and materials shall include those described in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended; 42
U.S.C. Section 9601 et seq., the Resource Conservation and Recover Act, as
amended 42 U.S.C. Section 6901 et seq., any applicable state or local laws and
the regulations adopted under these acts. If any lender or governmental agency
shall ever require testing to ascertain whether or not there has been any
release of hazardous materials, then the reasonable costs thereof shall be
reimbursed by Tenant to Landlord upon demand as additional charges if such
requirement applies to the Premises. In addition, Tenant shall execute
affidavits, representations and the like from time to time at Landlord's request
concerning Tenant's best knowledge and belief regarding the presence of
hazardous substances or materials on the Premises. In all events, Tenant shall
indemnify Landlord in the manner elsewhere provided in this lease from any
release of hazardous materials on the Premises occurring while Tenant is in
possession, or elsewhere if caused by Tenant or persons acting under Tenant. The
within covenants shall survive the expiration or earlier termination of the
lease term.

    Compliance by Tenant with any provision of this Section 7.5 shall not be
deemed a waiver of any other provision of this Lease. Without limiting the
foregoing, Landlord's consent to any Environmental Activity shall not relieve
Tenant of its indemnity obligations under the terms hereof.

          7.6. Special Provisions Relating to The Americans With Disabilities
     Act of 1990.

               7.6.1. Allocation of Responsibility to Landlord. As between
Landlord and Tenant, Landlord shall be responsible that the public entrances,
stairways, corridors, elevators and elevators lobbies and other public areas in
the Building and in the Marketplace comply with the requirements of Title III of
the Americans with Disabilities Act of 1990 (42 U.S.C. 12181, et seq., The
Provisions Governing Public Accommodations and Services Operated by Private
Entities), and all regulations promulgated thereunder, and all amendments,
revisions or modifications thereto now or hereafter adopted or in effect in
connection therewith (hereinafter collectively referred to as the "ADA"), and to
take such actions and make such alterations and improvements as are necessary
for such compliance. All costs incurred by Landlord in discharging its
responsibilities under this Section 7.6.1 shall be included in Operating
Expenses as provided in Section 1.1.

               7.6.2. Allocation of Responsibility to Tenant. As between
Landlord and Tenant, at its sole cost and expense, shall be responsible that the
Premises, all Alterations to the Premises, Tenant's use and occupancy of the
Premises, and Tenant's performance of its obligations under this Lease, comply
with the requirements of the ADA, and to take such actions and make such
Alterations as are necessary for such compliance; provided, however, that Tenant
shall not make any such Alterations except upon Landlord's prior written consent
pursuant to the terms and conditions of this Lease. Tenant shall protect,
defend, indemnify and hold Landlord harmless from and against any claim, demand,
cause of action, obligation, liability, loss, cost or expense (including
reasonable attorneys' fees) which may be asserted against or incurred by
Landlord as a result of Tenant's failure in any respect to comply with its
obligations set forth hereinabove in this Section 7.6.2. Tenant's indemnity
obligations set forth in the immediately preceding sentence shall survive the
expiration or earlier termination of this Lease.

               7.6.3. General. Notwithstanding anything in this Lease to the
contrary, no act or omission of Landlord, including any approval, consent or
acceptance by Landlord or Landlord's agents, employees or other representatives,
shall be deemed an agreement, acknowledgment, warranty, or other representation
by Landlord that Tenant has complied with the ADA or that any action, alteration
or improvement by Tenant complies or will comply with the ADA or constitutes a
waiver by Landlord of Tenant's obligations to comply with the ADA under this
Lease or otherwise. Any failure of Landlord to comply with the obligations of
the ADA shall not relieve Tenant from any obligations under this Lease or
constitute or be construed as a constructive or other eviction of Tenant or
disturbance of Tenant's use and possession of the Premises.

     8.   Building Services.

          8.1. Maintenance of Marketplace. Landlord shall maintain the
Marketplace (other than the Premises and the premises of other tenants of the
Marketplace) in good order and condition, except for ordinary wear and tear,
damage by casualty or condemnation, or damage occasioned by the act or omission
of Tenant or Tenant's employees, agents, contractors, licensees or invitees,
which damage shall be repaired by Landlord at Tenant's expense (subject to the
provisions of Section 15). Landlord's maintenance of, and provision of services
to, the Building shall be performed in a manner consistent with that of
comparable office buildings in the Emeryville/Oakland, California area. Landlord
shall have the right in connection with its maintenance of the Marketplace
hereunder (i) to change the arrangement and/or location of any amenity,
installation or improvement in the public entrances, stairways, corridors,
<PAGE>

elevators and elevator lobbies, and other public areas in the Building, or other
public areas of the Marketplace, and (ii) to utilize portions of the public
areas in the Building and the Marketplace from time to time for entertainment,
displays, product shows, leasing of kiosks or such other uses that in Landlord's
sole judgment tend to attract the public, so long as such uses do not materially
interfere with or impair Tenant's access to or use or occupancy of the Premises.
Landlord shall not be in default under this Lease or liable for any damages
directly or indirectly resulting from or incidental to, nor shall the rental
reserved in this Lease be abated by reason of Landlord's failure to make any
repair or to perform any maintenance required to be made or performed by
Landlord under this Section 8.1, unless such failure shall persist for an
unreasonable time after written notice of the need for such repair or
maintenance is given to Landlord by Tenant.

          8.2. Building Standard Services. Landlord shall cause to be furnished
to Tenant: (i) tepid and cold water to those points of supply and in volumes
provided for general use of tenants in the Building; (ii) electricity up to the
Wattage Allowance for lighting and the operation of electrically powered office
equipment; (iii) heat, ventilation and air conditioning to the extent reasonably
required for the comfortable occupancy by Tenant of the Premises during the
period from 8:00 a.m. to 6:00 p.m. on weekdays (except Building holidays

applicable policies, regulations or guidelines adopted by any federal, state or
local governmental or quasi-governmental entities or utility suppliers; (iv)
elevator service; (v) lighting replacement for Building standard lights; (vi)
restroom supplies; (vii) window washing as determined by Landlord; and (viii)
security if and to the extent deemed appropriate by Landlord for the Marketplace

any direct, consequential or other loss, damage, death or injury related to any
interruption, discontinuance, malfunction, circumvention or failure of such
security service. Landlord shall use reasonable efforts to cause the services
described in items (i) - (iv) above to be provided 24 hours per day. Landlord
may establish in the Premises or other portions of the Marketplace such measures
as are required by laws, ordinances, rules or regulations or as it deems
necessary or appropriate (and are customary in comparable buildings in the
vicinity of the Building) to conserve energy, including automatic switching of
lights and/or more efficient forms of lighting.

          8.3. Interruption or Unavailability of Services. Rent shall not abate,
no constructive or other eviction shall be construed to have occurred, Tenant
shall not be relieved from any of its obligations under this Lease, and Landlord
shall not be in default hereunder or liable for any damages directly or
indirectly resulting from, the failure of Landlord to furnish, or delay in
furnishing, any maintenance or services under this Article 8 as a result of
repairs, alterations, improvements or any circumstances beyond Landlord's
reasonable control. Landlord shall use reasonable diligence to remedy any
failure or interruption in the furnishing of such maintenance or services and
Landlord shall use reasonable efforts to minimize interference with Tenant's
operation in connection with any repairs, alterations, or improvements
undertaken by Landlord.

          8.4. Tenant's Use of Excess Electricity and Water. Tenant shall not
without Landlord's prior consent, which shall not be unreasonably withheld, (1)
install in the Premises (A) lighting, the aggregate average daily power usage of
which exceeds the Lighting Wattage Allowance, or lighting and equipment, the
aggregate average daily power usage of which exceeds the Wattage Allowance, or
which requires a voltage other than 110 volts single-phase, (B) heat generating
equipment or lighting other than lights deemed standard for the Building, or (C)
supplementary air conditioning facilities, or (ii) permit occupancy levels in
excess of one person per two hundred (200) feet of Rentable Area. If, pursuant
to this Section 8.4, heat-generating equipment or lighting other than Building
standard lights are installed or used in the Premises, or occupancy levels are
greater than set forth above, or if the Premises or fixtures therein are
reconfigured by Alterations, and such equipment, lighting, occupancy levels or
Premises reconfiguration affects the temperature otherwise maintained by the
Building air conditioning system, or if equipment is installed in the Premises
which requires a separate temperature-controlled room, Landlord may, at
Landlord's election after notice to Tenant or upon Tenant's request, install
supplementary air conditioning facilities in the Premises, or otherwise modify
the ventilating and air conditioning serving the Premises, in order to maintain
the temperature otherwise maintained by the Building air conditioning system or
to serve such separate temperature-controlled room. Tenant shall pay the cost of
any transformers, additional risers, panel boards and other facilities if, when
and to the extent required to furnish power for, and all maintenance and service
costs of, any supplementary air conditioning facilities or modified ventilating
and air conditioning, or for lighting and/or equipment the power usage of which
exceeds the standards set forth in this Section 8.4. The capital, maintenance
and service costs of such facilities and modifications shall be paid by Tenant
as Rent, Landlord, at its election and at Tenant's expense, may also install and
maintain an electric current meter or water meter (together with all necessary
wiring and related equipment) at the Premises to measure the power and/or water
usage of such lighting, equipment or ventilation and air conditioning equipment,
or may otherwise cause such usage to be measured by reasonable methods.

          8.5. Provision of Additional Services. If Tenant desires services in
additional amounts or at different times than set forth in Section 8.2 above, or
any other services that are not provided for in this Lease, Tenant shall make a
request for such services to
<PAGE>

Landlord with such advance notice as Landlord may reasonably require. If
Landlord provides such services to Tenant, Tenant shall pay Landlord's charges
for such services within fifteen (15) days after Tenant's receipt of Landlord's
invoice.

     9.   Maintenance of Premises. Tenant shall, at all times during, the Term,
at Tenant's cost and expense, keep the Premises in good-condition and repair,
except for ordinary wear and tear and damage by casualty or condemnation. Except
as may be specifically set forth in this Lease, Landlord has no obligation to
alter, remodel, improve, reprint, decorate or paint the Premises, or any part
thereof, or any obligation respecting the condition, maintenance and repair of
the Premises or any other portion of the Marketplace. Tenant hereby waives all
rights, including those provided in California Civil Code Section 19.41 or any
successor statute, to make repairs which are Landlord's obligation under this
Lease at the expense of Landlord or to receive any setoff or abatement of Rent
or in lieu thereof to vacate the Premises or terminate this Lease.

    10.   Alterations to Premises.

          10.1. Landlord Consent Procedure. Tenant shall not make or permit to
be made any Alterations without Landlord's prior consent, which consent shall
not be unreasonably withheld, and in this regard Landlord's consent shall not be
required for nonstructural interior alterations costing less than $10,000 per
work of improvement. Any alterations to which Landlord has consented shall be
made in accordance with procedures as then established by Landlord and the
provisions of this Article 10.

          10.2. General Requirements. All alterations shall be made at Tenant's
cost and expense. Tenant shall be solely responsible for compliance with
applicable laws, ordinances, rules and regulations in connection with all
Alterations. Tenant shall be responsible for the cost of any additional
alterations required by applicable laws, ordinances, rules and regulations to be
made by Landlord to any portion of the Marketplace as a result of Alterations.
Tenant shall promptly commence or cause the commencement of construction of all
Alterations and complete or cause completion of the same with due diligence as
soon as possible after commencement in order to cause the least disruption to
Marketplace operations and occupants and to continue Tenant's business in the
Premises. In connection with installing or removing Alterations, Tenant shall
pay Landlord's then standard charges for review and approval of Tenant's plans,
specifications and working drawings, and administration by Landlord (or its
agent) of the construction, installation or removal of Alterations, and
restoration of the Premises to their previous condition.

          10.3. Removal of Alterations. If required by Landlord at the time
Landlord provides consent to an Alteration, Tenant shall, prior to the
expiration of the Term or termination of this Lease, remove such Alteration at
Tenant's cost and expense and restore the Premises to the condition existing
prior to the installation of such Alteration. If Tenant fails so to do, then
Landlord may remove such alteration and perform such restoration and Tenant
shall reimburse Landlord for Landlord's cost and expense incurred to perform
such removal and restoration (which obligation of Tenant shall survive the
expiration or earlier termination of this Lease). Tenant shall repair at its
cost and expense all damage to the Premises or Marketplace caused by the removal
of such Alteration. Subject to the foregoing provisions regarding removal, all
Alterations (including any above Building standard improvements to the Premises)
shall be Landlord's property and from and after the expiration or earlier
termination of this Lease remain on the Premises without compensation to Tenant.

     11.  Liens. Tenant shall keep the Premises and the Marketplace free from
any liens arising out of any work performed or obligations incurred by or for,
or materials furnished to, Tenant pursuant to this Lease or otherwise. Landlord
shall have the right to post and keep posted on the Premises any notices
required by law or which Landlord may deem to be proper for the protection of
Landlord, the Premises and the Marketplace from such liens and to take any other
action at the expense of Tenant that Landlord deems necessary or appropriate to
prevent, remove or discharge such liens. Tenant shall protect, defend, indemnify
and hold Landlord harmless from and against any claim, demand, cause of action,
obligation, liability, loss, cost or expense (including reasonable attorney's
fees) which may be asserted against or incurred by Landlord as a result of
Tenant's failure to comply with the foregoing obligation (which indemnity
obligation shall survive the expiration or earlier termination of this Lease).

     12.  Damage of Destruction.

          12.1. Obligation to Repair. Except as otherwise provided in this
Article 12 if the Premises, or any other portion of the Marketplace necessary
for Tenant's use and occupancy of the Premises, are damaged or destroyed by fire
or other casualty, Landlord shall, within thirty (30) days after such event,
notify Tenant of the estimated time, in Landlord's reasonable judgment, required
to repair such damage or destruction. If Landlord's estimate of time is less
than two hundred seventy (270) days after the date of damage or destruction,
then (i) Landlord shall proceed with all due diligence to repair the Premises,
and/or the portion of the Marketplace
<PAGE>

necessary for Tenant's use and occupancy of the premises, to substantially the
condition existing immediately before such damage or destruction, as permitted
by and subject to then applicable laws, ordinances, rules and regulations; (ii)
this Lease shall remain in full force and effect; and (iii) to the extent such
damage or destruction did not result from the negligence or willful act or
omission of Tenant or Tenant's subtenants or any of their respective employees,
agents, contractors, invitees or licensees, Base Rent shall share for such part
of the Premises rendered unusable by Tenant in the conduct of its business
during the time such part is so unusable, in the proportion that the Rentable
Area continued in the unusable part of the Premises bears to the total Rentable
Area of the Premises.

          12.2. Landlord's Election. If Landlord determines that the necessary
repairs cannot be completed within two hundred seventy (270) days after the date
of damage or destruction, or if such damage or destruction arises from causes
not covered by Landlord's insurance policy then in force ("Uninsured Loss") and
the Uninsured Loss exceeds 2% of the replacement cost of the Building, Landlord
may elect, in its notice to Tenant pursuant to Section 12.1 to (i) terminate
this Lease or (ii) repair the Premises or the portion of the Marketplace
necessary for Tenant's use and occupancy of the Premises pursuant to the
applicable provisions of Section 12.1 above. In addition, if Landlord determines
that the necessary repairs cannot be completed within two hundred seventy (270)
days after the date of damage or destruction, then Tenant shall have the right
for a period of twenty (20) days after receipt of Landlord's notice, to elect to
terminate this Lease. If Landlord or Tenant terminates this Lease, then this
Lease shall terminate as of the date of occurrence of the damage or destruction.

          12.3. Cost of Repairs. Landlord shall pay the cost for repair of the
Marketplace and all improvements in the Premises, other than any Alterations.
Tenant shall pay the costs to repair all Alterations. Tenant shall also replace
or repair, at Tenant's cost and expense. Tenant's movable furniture, equipment,
trade fixtures and other personal property in the Premises which Tenant shall be
responsible for insuring during the Term of this Lease.

          12.4. Damages at End of Term. Notwithstanding anything to the contrary
contained in this Article 12, if the Premises, or any other portion thereof or
of the Marketplace, are damaged or destroyed by fire or other casualty within
the last eighteen (18) months of the Term, then Landlord shall have the right,
in its sole discretion, to terminate this Lease by notice to Tenant given within
ninety (90) days after the date of such event. Such termination shall be
effective on the date specified in Landlord's notice to Tenant, but in no event
later than the end of such 90-day period.

          12.5. Waiver of Statutes. The respective rights and obligations of
Landlord and Tenant in the event of any damage to or destruction of the
Premises, or any other portion of the Marketplace, are governed exclusively by
this Lease. Accordingly, Tenant hereby waives the provisions of any law to the
contrary, including California Civil Code Sections 1932(2) and 1933(4) providing
for the termination of a lease upon destruction of the leased property.

     13.  Eminent Domain.

          13.1. Effect of Taking. Except as otherwise provided in this Article
13, if all or any part of the Premises is taken as a result of the exercise of
the power of eminent domain or condemned for any public or quasi-public purpose,
or if any transfer is made in avoidance of such exercise of the power of eminent
domain (collectively, "taken" or a "taking"), this Lease shall terminate as to
the part of the Premises so taken as of the effective date of such taking. On a
taking of a portion of the Premises, Landlord and Tenant shall each have the
right to terminate this Lease by notice to the other given within thirty (30)
days after the effective date of such taking, if the portion of the Premises
taken is of such extent and nature so as to materially impair Tenant's business
use of the balance of the Premises, as reasonably determined by the party giving
such notice. On a taking of a portion of the Marketplace, Tenant shall have the
right to terminate this Lease by notice to Landlord given within thirty (30)
days after the effective date of such taking, if the portion of the Marketplace
(but not the Premises) taken is of such extent and nature so as to materially
impair Tenant's ability to use the Premises, as reasonably determined by Tenant.
Such termination shall be operative as of the effective date of the taking.
Landlord may also terminate this Lease on a taking of any other portion of the
Marketplace if Landlord reasonably determines that such taking is of such extent
and nature as to render the operation of the remaining Marketplace economically
infeasible or to require a substantial alteration or reconstruction of such
remaining portion. Landlord shall elect such termination by notice to Tenant
given within thirty (30) days after the effective date of such taking, and such
termination shall be operative as of the effective date of such taking. Upon a
taking of the Premises which does not result in a termination of this Lease, the
Base Rent shall thereafter be reduced as of the effective date of such taking in
the proportion that the Rentable Area of the Premises so taken bears to the
total Rentable Area of the Premises.
<PAGE>

          13.2. Condemnation Proceeds. Except as hereinafter provided, in the
event of any taking, Landlord shall have the right to all compensation, damages,
income, rent or awards made with respect thereto (collectively an "award"),
including any award for the value of the leasehold estate created by this Lease.
No award to Landlord shall be apportioned and, subject to Tenant's rights
hereinafter specified, Tenant hereby assigns to Landlord any right of Tenant in
any award made for any taking. So long as such claim will not reduce any award
otherwise payable to Landlord under this Section 13.2. Tenants may seek to
recover, at its cost and expense, as a separate claim, any damages or awards
payable on a taking of the Premises to compensate for the unamortized cost paid
by Tenant for the alterations, additions or improvements, if any, made by or on
behalf of Tenant during the initial improvement of the Premises pursuant to the
Work Letter and for any Alterations, or for Tenant's personal property taken, or
for interference with or interruption of Tenant's business (including goodwill),
or for Tenant's removal and relocation expenses.

          13.3. Restoration of Premises. On a taking of the Premises which does
not result in a termination of this Lease, Landlord and Tenant shall restore the
Premises as nearly as possible to the condition they were in prior to the taking
in accordance with the applicable provisions and allocation of responsibility
for repair and restoration of the Premises on damage or destruction pursuant to
Article 12 above, and both parties shall use any awards received by such party
attributable to the Premises for such purpose.

          13.4. Taking at End of Term. Notwithstanding anything to the contrary
contained in this Article 13, if the Premises, or any other portion thereof or
of the Marketplace, are taken within the last three hundred sixty-five (365)
days of the Term, then Landlord shall have the right, in its sole discretion, to
terminate this Lease by notice to Tenant given within ninety (90) days after the
date of such taking. Such termination shall be effective on the date specified
in Landlord's notice to Tenant, but in no event later than the end of such 90-
day period.

          13.5. Tenant Waiver. The rights and obligations of Landlord and Tenant
on any taking of the Premises or any other portion of the Marketplace are
governed exclusively by this Lease. Accordingly, Tenant hereby waives the
provisions of any law to the contrary, including California Code of Civil
Procedure Sections 1265.120 and 1265.130, or any similar successor statute.

     14.  Insurance.

          14.1. Liability Insurance. Landlord, with respect to the Marketplace,
and Tenant, at its cost and expense with respect to the Premises, shall each
maintain or cause to be maintained, from the Lease Date and throughout the Term,
a policy or policies of Commercial General Liability insurance with limits of
liability not less than Two Million Dollars ($2,000,000.00) per occurrence and
in the aggregate. Each policy shall contain coverage for blanket contractual
liability, personal injury liability, and premises operations, coverage deleting
liquor liability exclusions and, as to Tenant's insurance, fire legal liability.
Landlord shall have the right to approve the deductible under each policy of
Tenant's liability insurance, such approval not to be unreasonably withheld. In
addition, Landlord shall, at its sole cost and expense, keep in force an
extended coverage property damage insurance policy (excluding earthquake
coverage) on the Building in an amount not less than 100% of the replacement
cost of the Building; provided, however, that if at any time during the Term
such insurance is not available at commercially reasonable rates, then Landlord
shall, to the extent such insurance is available at commercially reasonable
rates, obtain extended coverage property damage insurance with the maximum
amount of coverage that is available at commercially reasonable rates.

          14.2. Form of Policies. All insurance required by this Article 14
shall be issued on an occurrence basis by solvent companies qualified to do
business in the State of California. Any insurance required under this Article
14 may be maintained under a "blanket policy", insuring other parties and other
locations, so long as the amount and coverage required to be provided hereunder
is not thereby diminished. Notwithstanding the foregoing, Landlord shall have
the right to self-insure against any of the risks required to be insured against
under this Article 14. Tenant shall provide Landlord a copy of each policy of
insurance or a certificate thereof certifying that the policies contain the
provisions required hereunder. Tenant shall deliver such policies or
certificates to Landlord within (30) days after the Lease Date, but in no event
less than ten (10) business days prior to the Commencement Date or such earlier
date as Tenant or Tenant's contractors, agents, licensees, invitees or employees
first enter the Premises and, upon renewal, not less than thirty (30) days prior
to the expiration of such coverage. All evidence of insurance provided to
Landlord shall provide (i) that Landlord, Landlord's managing agent and any
other person requested by Landlord who has an insurable interest is designated
as an additional insured without limitation as to coverage afforded under such
policy; (ii) for severability of interests or that the acts or omissions of one
of the insureds or additional insureds shall not reduce or affect coverage
available to any other insured or additional insured; (iii) that the insurer
agrees not to cancel or alter the policy without at least thirty (30) days prior
written notice to all additional insureds; (iv) that the aggregate liability
applies solely to the Premises and the remainder of the Marketplace; and (v)
that Tenant insurance is primary and noncontributing with any insurance carried
by Landlord.
<PAGE>

          14.3. Workers' Compensation Insurance. Tenant, at its sole cost and
expense, shall maintain Workers' Compensation insurance as required by law and
employer's liability insurance in an amount of not less than Five Hundred
Thousand Dollars ($500,000).

          14.4. Additional Tenant Insurance. Tenant, at its sole cost and
expense, shall maintain such other insurance as Landlord may reasonably require
from time to time, but in no event may Landlord require any other insurance
which is (i) not then being required of comparable tenants leasing comparable
amounts of space in comparable buildings in the vicinity of the Building or (ii)
not then available at commercially reasonable rates.

     15.  Waiver of Subrogation Rights. Notwithstanding anything to the contrary
contained in this Lease, Landlord and Tenant, for themselves and their
respective insurers, agree to and do hereby release each other of and from any
and all claims, demands, actions and causes of action that each may have or
claim to have against the other for loss or damage to property, both real and
personal, notwithstanding that any such loss or damage may be due to or result
from the negligence of either of the parties hereto or their respective
employees or agents. Each party shall, to the extent such insurance endorsement
is lawfully available at commercially reasonable rates, obtain or cause to be
obtained, for the benefit of the other party, a waiver of any right of
subrogation which the insurer of such party may acquire against the other party
by virtue of the payment of any such loss covered by such insurance.

     16.  Tenant's Waiver of Liabilities and Indemnification.

          16.1. Waiver and Release. Except to the extent due to the gross
negligence or willful misconduct of Landlord, Landlord shall not be liable to
Tenant or Tenant's employees, agents, contractors, licensees or invitees for,
and Tenant waives and releases Landlord and Landlord's managing agent from, all
claims for loss or damage to any property or injury, illness or death of any
person in, upon or about the Premises and/or any other portion of the
Marketplace (including claims caused in whole or in part by the act, omission,
or neglect of other tenants, contractors, licensees, invitees or other occupants
of the Marketplace or their agents or employees). The waiver and release
contained in this Section 16.1 extends to the officers, directors, shareholders,
partners, employees, agents and representatives of Landlord.

          16.2. Indemnification of Landlord. Tenant shall indemnify, defend,
protect and hold Landlord harmless of and from any and all loss, liens,
liability, claims, causes of action, damage, injury, cost or expense arising out
of or in connection with (i) the making of any alterations, additions or other
improvements made by or on behalf of Tenant during the initial improvement of
the Premises pursuant to the Work Letter or any Alterations, or (ii) injury to
or death of persons or damage to property occurring or resulting directly or
indirectly from: (A) the use or occupancy of, or the conduct of business in, the
Premises by Tenant or its subtenants or any of their respective officers,
directors, employees, agents, contractors, invitees or licensees; (B) any other
occurrence or condition in or on the Premises; and (C) acts, neglect or
omissions of Tenant, or its subtenants or any of their respective officers,
directors, employees, agents, contractors, invitees or licensees, in or about
any portion of the Marketplace. Tenant's indemnity obligation includes
reasonable attorneys' fees and costs, investigation costs and all other
reasonable costs and expenses incurred by Landlord. If Landlord disapproves the
legal counsel proposed by Tenant for the defense of any claim indemnified
against hereunder, Landlord shall have the right to appoint its own legal
counsel, the reasonable fees, costs and expenses of which shall be included as
part of Tenant's indemnity obligation hereunder. The indemnification contained
in this Section 16.2 shall extend to the officers, directors, shareholders,
partners, employees, agents and representatives of Landlord.

          16.3. Indemnification of Tenant. Landlord shall indemnify, defend,
protect and hold Tenant harmless of and from any and all loss, liens, liability,
claims, causes of action, damage, injury, cost or expense arising out of or in
connection with (i) any breach or default by Landlord in the performance of any
of its obligations under this Lease, or (ii) any loss or damage to property or
injury to person occurring in the public entrances, stairways, corridors,
elevators and elevator lobbies, and other public areas in the Building or the
other public areas in the Marketplace (except for such loss, damage or injury
for which Tenant is obligated to indemnify Landlord under Section 16.2).

     17.  Assignment and Subletting.

          17.1. Compliance Required. Tenant shall not, directly or indirectly,
voluntary or by operation of law, sell, assign or otherwise transfer this Lease,
or any interest herein (collectively, "assign" or "assignment"), or sublet the
Premises, or any part thereof, or permit the occupancy of the Premises by any
person other than Tenant (collectively, "sublease" or "subletting", the assignee
or sublessee under and assignment or sublease being referred to as a
"transferee"), without Landlord's prior consent given or withheld in
<PAGE>

accordance with the express standards and conditions of this Article 17 and
compliance with the other provisions of this Article 17. Any assignment or
subletting made in violation of this Article 17 shall be void. As used herein,
on "assignment" includes any sale or other transfer (such as by consolidation,
merger or reorganization) of a majority of the voting stock of Tenant, if Tenant
is a corporation, or any sale or other transfer of a majority of the beneficial
interest in Tenant, if Tenant is any other form of entity. Tenant acknowledges
and agrees that the limitations on Tenant's right to sublet or assign which are
set forth in this Article 17 are reasonable and, in particular, that the express
standards and conditions upon Tenant's right to assign or sublet which are set
forth in this Article 17 are reasonable as of the Lease Date. Notwithstanding
the foregoing, an assignment shall not include any of the following
(collectively, "Exempt Transfers"): (i) the sale of substantially all of the
assets of Tenant, so long as the purchaser of such assets assumes all of
Tenant's obligations under this Lease; (ii) the transfer of any stock at any
time that the shares of Tenant are publicly traded; and (iii) any merger;
consolidation or other nonbankruptcy reorganization so long as the net worth of
the survivor is the same or better as the Tenant immediately prior to the
consummation of the transaction and so longs as the survivor assumes all of the
Tenant's obligations under this Lease. In addition to the foregoing, Landlord
shall have no right to disapprove a sublease to any entity controlling,
controlled by, or under common control with Tenant (an "Exempt Sublease"). The
transferee under an Exempt Transfer or an Exempt Sublease shall be referred to
as an "Exempt Transferee".

          17.2. Request by Tenant Landlord Response. If Tenant desires to effect
an assignment of sublease, Tenant shall submit to Landlord a request for consent
together with the identity of the parties to the transaction, the nature of the
transferee's proposed business use for the Premises, the proposed documentation
for and terms of the transaction, and all other information reasonably requested
by Landlord concerning the proposed transaction and the parties involved
therein, including certified financial information, credit reports, the business
background and references regarding the transferee, and an opportunity to meet
and interview the transferee. Within twenty (20) days after the later of such
interview or the receipt of all such information required by Landlord, or within
thirty (30) days after the date of Tenant's request to Landlord if Landlord does
not request additional information or an interview, Landlord shall have the
right, by notice to Tenant, to: (i) consent to the assignment or sublease,
subject to the terms of this Article 17; (ii) decline to consent to the
assignment or sublease; (iii) in the case of a subletting, to sublet from Tenant
the portion or the Premises proposed to be sublet on the terms and conditions
set forth in Tenant's request to Landlord, unless the rent terms exceed the
allocable Rent payable by Tenant hereunder, in which event only such Rent shall
be payable by Landlord under such subletting; or (iv) terminate this Lease as to
the affected portion of the Premises as of the date specified by Tenant as the
effective date of the proposed assignment or sublease, in which event Tenant
will be relieved of all unsecured obligations hereunder as to such portion as of
such date, other than those obligations which survive termination of this Lease.
If Landlord elects so to terminate, Tenant shall have the right, by notice to
Landlord within five (5) days after Landlord's exercise of such right, to resend
its request for the proposed assignment or subletting, in which event this Lease
shall not terminate and shall remain in full force and effect. Notwithstanding
the foregoing or the following, Landlord shall have no right to exercise the
Termination Option with respect to any Exempt Sublease.

          17.3. Conditions for Landlord Approval. In the event Landlord elects
not to sublet from Tenant or terminate this Lease (in whole or in part) as
provided in clauses (iii) and (iv) of Section 17.2, Landlord shall not
unreasonably withhold its consent to a proposed subletting or assignment by
Tenant. Without limiting the grounds on which it may be reasonable for Landlord
to withhold its consent to an assignment or sublease, Tenant agrees that
Landlord would be acting reasonably in withholding its consent in the following
instances: (i) if Tenant is in default under this Lease; (ii) if the transferee
is a governmental or quasi-governmental agency, foreign or domestic; (iii) if
the transferee is an existing tenant in the Building (iv) if, in Landlord's sole
judgment, the transferee's business, use and/or occupancy of the Premises would
(A) violate any of the terms of this Lease or the lease of any other tenant in
the Marketplace, or (B) not be comparable to and compatible with the types of
use by other tenants in the Building, (C) fall within any category of use for
which Landlord would not then lease space in the Building under its leasing
guidelines and policies then in effect, (D) require any Alterations which would
reduce the value of the existing leasehold improvements in the Premises, or (E)
result in increased density per floor or require increased services by Landlord;
(v) in the case of a sublease, it would result in more than three (3)
occupancies in the Premises, including Tenant and subtenants; (vi) if the
financial condition of the transferee does not meet the requirements applied by
Landlord for other tenants in the Building under leases with comparable terms,
or in Landlord's sole judgment the business reputation of the transferee is not
consistent with that of other tenants of the Building; or (vii) in the case of a
sublease, the rent payable by the subtenant is less than the then prevailing
rate being charged by Landlord for the lease of comparable space in the
Building. If Landlord consents to an assignment or sublease, the terms of such
assignment or sublease transaction shall not be modified without Landlord's
prior written consent pursuant to this Article 17. Landlord's consent to an
assignment or subletting shall not be deemed consent to any subsequent
assignment or subletting.

          17.4. Costs and Expenses. As a condition to the effectiveness of any
assignment or subletting under this Article 17, Tenant shall pay to Landlord a
processing fee of Five Hundred Dollars ($500.00) and all reasonable costs and
expenses, including attorneys'
<PAGE>

fees and disbursements, incurred by Landlord in evaluating Tenant's requests for
assignment or sublease, whether or not Landlord consents to an assignment or
sublease. Tenant shall pay the processing fee with Tenant's request for
Landlord's consent under Section 17.2. Tenant shall also pay to Landlord all
costs and expenses incurred by Landlord due to a transferee taking possession of
the Premises, including freight elevator operation, security service, janitorial
service and rubbish removal.

          17.5. Payment of Excess Rent and Other Consideration. Tenant shall
also pay to Landlord, promptly upon Tenant's receipt thereof, fifty-percent
(50%) of any and all rent sums or other consideration, howsoever denominated,
realized by Tenant in connection with any assignment or sublease transaction in
excess of the Base Rent and Impositions, Operating Expenses and Real Estate
Taxes payable hereunder (prorated to reflect the Rent allocable to the portion
of the Premises if a sublease), after first deducting, (i) in the case of an
assignment, the unamortized reasonable cost of Alterations paid for by Tenant
and reasonable real estate commissions paid by Tenant in connection with such
assignment and, (ii) in the case of a sublease, the reasonable cost of
Alterations made to the Premises at Tenant's cost to effect the sublease, and
the reasonable amount of any real estate commissions paid by Tenant, both
amortized over the term of the sublease.

          17.6. Assumption of Obligations; Further Restrictions on Subletting.
Each assignee shall, concurrently with any assignment, assume all obligations of
Tenant under this Lease. Each sublease shall be made subject to this Lease and
all of the terms, covenants and conditions contained herein; and the surrender
of this Lease by Tenant, or a mutual cancellation thereof, or the termination of
this Lease in accordance with its terms, shall not work a merger and shall, at
the option of Landlord, terminate all or any existing subleases or operate as an
assignment to Landlord of any or all such subleases. No sublessee (other than
Landlord) shall have the right further to sublet. Any assignment by a sublessee
of its sublease shall be subject to Landlord's prior consent in the same manner
as a sublease by Tenant. No sublease, once consented to by Landlord, shall be
modified without Landlord's prior consent. No assignment or sublease shall be
binding on Landlord unless the transferee delivers to Landlord a fully executed
counterpart of the assignment or sublease which contains the assumption by the
assignee, or recognition by the sublessee, of the provisions of this Section
17.6 in form and substance satisfactory to Landlord, but the failure or refusal
of a transferee to deliver such instrument shall not release or discharge such
transferee from the provisions and obligations of this Section 17.6 but such
failure shall constitute a default by Tenant under this Lease.

          17.7. No Release. No assignment or sublease shall release Tenant from
its obligations under this Lease, whether arising before or after the assignment
or sublease. The acceptance of Rent by Landlord from any other person shall not
be deemed a waiver by Landlord of any provisions of this Article 17. On a
default by any assignee of Tenant in the performance of any of the terms,
covenants or conditions of this Lease, Landlord may proceed directly against
Tenant without the necessity of commencing or exhausting remedies against such
assignee. No consent by Landlord to any further assignments or sublettings of
this Lease, or any modification, amendment or termination of this Lease, or
extension, waiver or modification or payment or any other obligations under this
Lease, or any other action by Landlord with respect to any assignee or
sublessee, or the insolvency, or bankruptcy or default of any such assignee or
sublessee, shall affect the continuing liability of Tenant for its obligations
under this Lease and Tenant waives any defense arising out of or based thereon,
including any suretyship defense of exoneration. Landlord shall have no
obligation to notify Tenant or obtain Tenant's consent with respect to any of
the foregoing matters.

          17.8. No Encumbrance. Notwithstanding anything to the contrary
contained in this Article 17, Tenant shall have no right to encumber, pledge,
hypothecate or otherwise transfer this Lease, or any of Tenant's interest or
rights hereunder, at security for any obligation or liability of Tenant.

     18.  Rules and Regulations. Tenant shall observe and comply, and shall
cause its sublessees, employees, agents, contractors, licensees and invitees to
observe and comply, with the Rules and Regulations of the Marketplace, a copy of
which are attached to this Lease as Exhibit D, and, after notice thereof, with
all modifications and additions thereto from time to time promulgated in writing
by Landlord, but only to the extent such modifications and additions are
reasonable, non-discriminatory, and not materially inconsistent with any of the
rights of Tenant granted by this Lease. Landlord shall not be responsible to
Tenant, or Tenant's sublessees, employees, agents, contractors, licensees or
invitees, for noncompliance with any Rules and Regulations of the Marketplace by
any other tenant, sublessee, employee, agent, contractor, licensee, invitee or
other occupant of the Marketplace.

     19.  Entry of Premises by Landlord.

          19.1. Right to Enter. Upon reasonable advance notice to Tenant (except
in emergencies or in order to provide regularly scheduled or other routine
Building standard services or additional services requested by Tenant, or post
notices of non-responsibility
<PAGE>

or other notices permitted or required by law when no such notice shall be
required), Landlord and its authorized agents, employees, and contractors may
enter the Premises at reasonable hours to: (i) inspect the same; (ii) determine
Tenant's compliance with its obligations hereunder; (iii) exhibit the same to
prospective purchasers, lenders or tenants; (iv) supply any services to be
provided by Landlord hereunder;; (v) post notices of non-responsibility or other
notices permitted or required by law; (vi) make repairs, improvements or
alterations, or perform maintenance in or to, the Premises or any other portion
of the Marketplace, including Building systems; and (vii) perform such other
functions as Landlord deems reasonably necessary or desirable. Landlord may also
grant access to the Premises to government or utility representatives and bring
and use on or about the Premises such equipment as reasonably necessary to
accomplish the purposes of Landlord's entry. Landlord shall use reasonable good
faith efforts to effect all entries and perform all work hereunder in such
manner as to minimize interference with Tenant's use and occupancy of the
Premises. Landlord shall have and retain keys with which to unlock all of the
doors in or to the Premises (excluding Tenant's vaults, safes and similar secure
areas designated in writing by Tenant in advance), and Landlord shall have the
right to use any and all means which Landlord may deem proper in an emergency in
order to obtain entry to the Premises, including secure areas.

          19.2. Tenant Waiver of Claims. Tenant waives any claim for damages for
any inconvenience to or interference with Tenant's business, or any loss of
occupancy or quiet enjoyment of the Premises, or any other loss, occasioned by
any entry effected or work performed under this Article 19, and Tenant shall not
be entitled to any abatement of Rent by reason of the exercise of any such right
of entry or performance of such work. No entry to the Premises by Landlord or
anyone acting under Landlord shall constitute a forcible or unlawful entry into,
or a detainer of, the Premises or an eviction, actual or constructive, of Tenant
from the Premises, or any portion thereof.

     20.  Default and Remedies.

          20.1. Events of Default. The occurrence of any of the following events
shall constitute a default by Tenant under this Lease:

               a. Nonpayment of Rent. Failure to pay any Rent when due.

               b.  Unpermitted Assignment. An assignment or sublease made in
contravention of any of the provisions of Article 17 above.

               c.  Abandonment. Abandonment of the Premises for a continuous
period in excess of five (5) business days. For purposes hereof, "abandonment"
means cessation by Tenant of the conduct of its business in the Premises or
removal from the Premises of the personal property, equipment and furnishings
used by Tenant in its business in the Premises.

               d. Other Obligations. Failure to perform or fulfill any other
obligation, covenant, condition or agreement under this Lease.

               e. Bankruptcy and Insolvency. A general assignment by Tenant for
the benefit of creditors, any action or proceeding commenced by Tenant under any
insolvency or bankruptcy act or under any other statute or regulation for
protection from creditors, or any such action commenced against Tenant and not
discharged within sixty (60) days after the date of commencement, the employment
or appointment of a receiver or trustee to take possession of all or
substantially all of Tenant's assets or the Premises where possession is not
returned to Tenant within thirty (30) days; the attachment, execution or other
judicial seizure of all or substantially all of Tenant's assets or the Premises,
if such attachment or other seizure remains undismissed or undischarged for a
period of fifteen (15) days after the levy thereof, the admission by Tenant in
writing of its inability to pay its debts as they become due; or the filing by
Tenant of a petition seeking any reorganization, arrangement, composition,
readjustment, liquidation, dissolution or similar relief under any present or
future statute, law or regulation, the filing by Tenant of an answer admitting
or failing timely to contest a material allegation of a petition filed against
Tenant in any such proceeding or, if within thirty (30) days after the
commencement of any such proceeding against Tenant, such proceeding is not
dismissed. For purposes of this Section 20.1(e), "Tenant" means Tenant and any
partner of Tenant, if Tenant is a partnership, or any person or entity
comprising Tenant, if Tenant is comprised of more than one person or entity, or
any guarantor of Tenant's obligations, or any of them, under this Lease.

          20.2. Notice to Tenant. Upon the occurrence of any default, Landlord
shall give Tenant notice thereof. Such notice shall replace rather than
supplement any equivalent or similar statutory notice, including any notices
required by California Code of Civil Procedure Section 1161 or any similar or
successor statute; and giving of such notice in the manner required by Article
28 shall replace and satisfy any service-of-notice procedures set forth in any
statute, including those required by California Code of Civil Procedure Section
1162 or any similar or successor statute. If a time period is specified below
for cure of such default, then Tenant
<PAGE>

may cure such default within such time period. To the fullest extent allowed by
law, Tenant hereby waives any right under law now or hereinafter enacted to any
other time period for cure of default.

        a. Nonpayment of Rent. For failure to pay Rent, within five (5) days
after Landlord's notice, unless Tenant has failed more than two (2) times during
any calendar year timely to pay any Rent, in which event no cure period shall
apply for the balance of such calendar year.

        b. Other Obligations. For failure to perform any obligation, covenant,
condition or agreement under this Lease (other than nonpayment of Rent, an
assignment or subletting in violation of Article 17 or Tenant's abandonment of
the Premises) within ten (10) days after Landlord's notice or, if the failure is
of a nature requiring more than ten (10) days to cure, then an additional thirty
(30) days after the expiration of such 10-day period, but only if Tenant
commences cure within such 10-day period and thereafter diligently pursues such
cure to completion within such additional 30-day period. If Tenant has failed to
perform any such obligation, covenant, condition or agreement more than two (2)
times during any calendar year and notice of such event of default has been
given by Landlord in each instance, then no cure period shall apply for the
balance of such calendar year.

        c. No Cure Period. No cure period shall apply for any other event of
default specified in Section 20.1.

    20.3. Remedies Upon Occurrence of Default. On the occurrence of a default
which Tenant fails to cure after notice and expiration of the time period for
cure, if any, specified in Section 20.2. above, Landlord shall have the right
either (i) to terminate this Lease and recover possession of the Premises, or
(ii) to continue this Lease in effect and enforce all Landlord's rights and
remedies under California Civil Code Section 1951.4 (by which Landlord may
recover Rent as it becomes due, subject to Tenant's right to assign pursuant to
Article 17). Landlord may store any property of Tenant located in the Premises
at Tenant's expense or otherwise dispose of such property in the manner provided
by law. If Landlord does not terminate this Lease, Tenant shall in addition to
continuing to pay all Rent when due, also pay Landlord's costs of attempting to
relet the Premises, any repairs and alterations necessary to prepare the
Premises for such reletting, and brokerage commissions and attorney's fees
incurred in connection therewith, less the rents, if any, actually received from
such reletting. Notwithstanding Landlord's election to continue this Lease in
effect, Landlord may at any time thereafter terminate this Lease pursuant to
this Section 20.3.

    20.4. Damages Upon Termination. If and when Landlord terminates this Lease
pursuant to Section 20.3. Landlord may exercise all its rights and remedies
available under California Civil Code Section 1951.2, including the right to
recover from Tenant the worth at the time of award of the amount by which the
unpaid Rent for the balance of the Term after the time of award exceeds the
amount of such Rent loss that the Tenant proves could have been reasonably
avoided. As used herein and in Civil Code Section 1951.2, "time of award" means
either the date upon which Tenant pays to Landlord the amount recoverable by
Landlord, or the date of entry of any determination, order or judgment of any
court or other legally constituted body determining the amount recoverable,
whichever occurs first.

    20.5. Computation of Certain Rent for Purposes of Default. For purposes of
computing unpaid Rent pursuant to Section 20.4 above, Escalation Rent for the
balance of the Term shall be determined by averaging the amount paid by Tenant
as Escalation Rent for the calendar year prior to the year in which the default
occurred (or, if the prior year is the Base Year or such default occurs during
the Base Year, Escalation Rent shall be based on Landlord's operating budget for
the Building for the Base Year), increasing such average amount for each
calendar year (or portion thereof) remaining in the balance of the Term at a per
annum compounded rate equal to the mean average rate of increase for the
preceding five (5) calendar years in the United States Department of Labor,
Bureau of Labor Statistics, Consumer Price Index (All Urban Consumers, All
Items, 1982-1984 = 100) for the Metropolitan Area of which San Francisco,
California, is a part, and adding together the resulting amounts. If such Index
is discontinued or revised, such computation shall be made by reference to the
index designated as the successor or substitute index by the United States
Department of Labor, Bureau of Labor Statistics, or its successor agency, and if
none is designated, by a comparable index as determined by Landlord in its sole
discretion, which would likely achieve a comparable result to that achieved by
the use of the Consumer Price Index. If the base year of the Consumer Price
Index is changed, then the conversion factor specified by the Bureau, or
successor agency, shall be utilized to determine the Consumer Price Index.

    20.6. Landlord's Right to Cure Defaults. If Tenant fails to pay Rent (other
than Base Rent and Escalation Rent) required to be paid by it hereunder, or
fails to perform any other obligation under this Lease, and Tenant fails to cure
such default within the applicable cure period, if any, specified in Section
20.2 above, then Landlord may, without waiving any of Landlord's rights in
connection therewith or releasing Tenant from any of its obligations or such
default, make any such payment or perform such other obligation on behalf of
Tenant. All payments so made by Landlord, and all costs and expenses
<PAGE>

incurred by Landlord to perform such obligations, shall be due and payable by
Tenant as Rent immediately upon receipt of Landlord's demand therefor.

    20.7. Remedies Cumulative. The rights and remedies of Landlord under this
Lease are cumulative in addition to, and not in lieu of, any other rights and
remedies available to Landlord at law or in equity. Landlord's pursuit of any
such right or remedy shall not constitute a waiver or election of remedies with
respect to any other right or remedy.

  21. Subordination, Attornment and Nondisturbance.

    21.1. Subordination and Attornment. This Lease and all of Tenant's rights
hereunder shall be subordinate to any ground lease or underlying lease, and the
lien of any mortgage, deed of trust, or any other security instrument now or
hereafter affecting or encumbering the Marketplace, or any part thereof or
interest therein, and to any and all advances made on the security thereof or
Landlord's interest therein, and to all renewals, modifications, consolidations,
replacements and extensions thereof (an "encumbrance", the holder of the
beneficial interest thereunder being referred to as an "encumbrancer"). An
encumbrancer may, however, subordinate its encumbrance to this Lease, and if an
encumbrancer so elects by notice to Tenant, this Lease shall be deemed prior to
such encumbrance. If any encumbrance to which this Lease is subordinate is
foreclosed, or a deed in lieu of foreclosure is given to the encumbrancer
thereunder, Tenant shall attorn to the purchaser at the foreclosure sale or to
the grantee under the deed in lieu of foreclosure; and if any encumbrance
consisting of a ground lease or underlying lease to which this Lease is
subordinate is terminated, Tenant shall attorn to the lessor thereof. Tenant
shall execute, acknowledge and deliver in the form requested by Landlord or any
encumbrancer, any documents required to evidence or effectuate the subordination
hereunder, or to make this Lease prior to the lien of any encumbrance, or to
evidence such attornment.

    21.2. Nondisturbance. If any encumbrance to which this Lease is subordinate
is foreclosed, or a deed in lieu of foreclosure is given to the encumbrancer
thereunder, or if any encumbrance consisting of a ground lease or underlying
lease to which this Lease is subordinate is terminated, this Lease shall not
terminate, and the rights and possession of Tenant under this Lease shall not be
disturbed if (i) no default by Tenant then exists under this Lease; (ii) Tenant
attorns to the purchaser, grantee, or successor lessor as provided in Section
21.1 above or, if requested, enters into a new lease for the balance of the Term
upon the same terms and provisions contained in this Lease; and (iii) Tenant
enters into a written agreement in a form reasonably acceptable to such
encumbrancer with respect to subordination, attornment and non-disturbance.

  22. Sale or Transfer by Landlord; Lease Non-Recourse.

    22.1. Release of Landlord on Transfer. Landlord may at any time transfer, in
whole or in part, its right, title and interest under this Lease and in the
Marketplace, or any portion thereof. If the original Landlord hereunder, or any
successor to such original Landlord, transfers (by sale, assignment or
otherwise) its right, title or interest in the Building, all liabilities and
obligations of the original Landlord or such successor under this Lease accruing
after such transfer shall terminate, the original Landlord or such successor
shall automatically be released therefrom, and thereupon all such liabilities
and obligations shall be binding upon the new owner. Tenant shall attorn to each
such new owner.

    22.2. Lease. Nonrecourse to Landlord. Landlord shall in no event be
personally liable under this Lease, and Tenant shall look solely to Landlord's
interest in the Building, for recovery of any damages for breach of this Lease
by Landlord or on any judgment in connection therewith. None of the persons or
entities comprising or representing Landlord (whether partners, shareholders,
officers, directors, trustees, employees, beneficiaries, agents or otherwise)
shall ever be personally liable under this Lease or liable for any such damages
or judgment and Tenant shall have no right to effect any levy of execution
against any assets of such persons or entities on account of any such liability
or judgment. Any lien obtained by Tenant to enforce any such judgment, and any
levy of execution thereon, shall be subject and subordinate to all encumbrances
as specified in Article 21 above.

  23. Estoppel Certificate.

    23.1. Procedure and Content. From time to time, and within ten (10) days
after written notice by Landlord, Tenant shall execute, acknowledge, and deliver
to Landlord a certificate as specified by Landlord certifying: (i) that this
Lease is unmodified and in full force and effect (or, if there have been
modifications, that this Lease is in full force and effect, as modified, and
identifying each
<PAGE>

modification); (ii) the Commencement Date and Expiration Date; (iii) that Tenant
has accepted the Premises (or the reasons Tenant has not accepted the Premises),
and if Landlord has agreed to make any alterations or improvements to the
Premises, that Landlord has properly completed such alterations or improvements
(or the reasons why Landlord has not done so); (iv) the amount of the Base Rent
and current Escalation Rent, if any, and the date to which such Rent has been
paid; (v) that Tenant has not committed any event of default, except as to any
events of default specified in the certificate, and whether there are any
existing defenses against the enforcement of Tenant's obligations under this
Lease; (vi) that no default of Landlord id claimed by Tenant, except as to any
defaults specified in the certificate; and (vii) such other matters as may be
requested by Landlord.

    23.2. Effect of Certificate. Any such certificate may be relied upon by any
prospective purchaser of any part or interest in the Marketplace or encumbrancer
(as defined in Section 21.1) and, at Landlord's request, Tenant shall deliver
such certificate to Landlord and/or to any such entity and shall agree to such
notice and cure provisions and such other matters as such entity may reasonably
require. In addition, at Landlord's request, Tenant shall provide to Landlord
for delivery to any such entity such information, including financial
information, that may reasonably be requested by any such entity. Any such
certificate shall constitute a waiver by Tenant of any claims Tenant may have in
contravention to the information contained in such certificate and Tenant shall
be estopped from asserting any such claim. If Tenant fails or refuses to give a
certificate hereunder within the time period herein specified, then the
information contained in such certificate as submitted by Landlord shall be
deemed correct for all purposes, but Landlord shall have the right to treat such
failure or refusal as a default by Tenant. Any prospective purchaser or
encumbrancer shall sign a confidentiality agreement regarding the non-disclosure
of Tenant's financial information prior to delivery of such information to the
prospective purchaser or encumbrancer.

  24. No Light, Air or View Easement. Nothing contained in this Lease shall be
deemed, either expressly or by implication, to create any easement for light and
air or access to any view. Any diminution or shutting off of light, air or view
to or from the Premises by any structure which now exists or which may hereafter
be erected, whether by Landlord or any other person, shall in no way affect this
Lease or Tenant's obligations hereunder, entitle Tenant to any reduction of
Rent, or impose any liability on Landlord.

  25. Holding Over. No holding over by Tenant shall operate to extend the Term.
If Tenant remains in possession of the Premises after expiration or termination
of this Lease, unless otherwise agreed by Landlord in writing, then (i) Tenant
shall become a tenant at sufferance upon all the applicable terms and conditions
of this Lease, except that Base Rent shall be increased to equal 200% of the
Base Rent then in effect, (ii) Tenant shall indemnify, defend, protect and hold
harmless Landlord, and any tenant to whom Landlord has leased all or part of the
Premises, from any and all liability, loss, damages, costs or expense (including
loss of Rent to Landlord or additional rent payable by such tenant and
reasonable attorneys' fees) suffered or incurred by either Landlord or such
tenant resulting from Tenant's failure timely to vacate the Premises; and (iii)
such holding over by Tenant shall constitute a default by Tenant.

  26. Security Deposit.

    26.1 Deposit Required; Adjustment to Amount of Security Deposit. Tenant
shall deposit with Landlord the Initial Security Deposit upon the execution of
this Lease by Tenant. On or before July 1, 1999, Tenant shall either (i) provide
written evidence, certified to be true, correct and complete by an authorized
officer of Tenant and otherwise satisfactory to Landlord, that Tenant has raised
equity in addition to that shown on Tenant's financial statement dated December
31, 1998 in the amount of at least Four Million and 00/100 Dollars
($4,000,000.00) (the "Additional Capital") or (ii) deposit with Landlord Twenty
Two Thousand Five Hundred and 00/100 Dollars ($22,500.00) (the "Additional
Security Deposit") in addition to the Initial Security Deposit that Tenant
deposited with Landlord upon execution of the Lease. For purposes of this Lease,
the term "Security Deposit" as used herein shall refer only to the Initial
Security Deposit prior to July 1, 1999, and on and after July 1, 1999, the term
"Security Deposit" shall refer to both the Initial Security Deposit and the
Additional Security Deposit (to the extent Tenant is required to deposit with
Landlord the Additional Security Deposit as provided above). If Tenant fails to
provide to Landlord satisfactory evidence of the Additional Capital on or before
July 1, 1999 and fails to deposit the Additional Security Deposit with Landlord
on or before July 1, 1999, monthly Base Rent shall increase to Fifteen Thousand
Six Hundred Forty Seven and 00/100 ($15,647.00) commencing on July 1, 1999. If
Tenant raises the Additional Capital after July 1, 1999, Landlord shall return
the Additional Security Deposit provided that Tenant shall have provided written
evidence of the Additional Capital, certified to be true, correct and complete
by an authorized officer of Tenant and otherwise satisfactory to Landlord.

    26.2 Consequence of Default. The Security Deposit shall be held by Landlord
as security for the performance by Tenant of all its obligations under this
Lease. If Tenant fails to pay any Rent due hereunder, or otherwise commits a
default with respect to any provision of this Lease, Landlord may use, apply or
retain all or any portion of the Security Deposit for the payment of any such
Rent or for the payment of any other amounts expended or incurred by Landlord by
reason of Tenant's default, or to compensate Landlord for any loss or damage
which Landlord may incur thereby (and in this regard Tenant hereby waives the
provisions of California Civil Code Section 1950.7(c) and any similar or
successor statute providing that Landlord may claim from a security deposit only
those sums reasonably necessary to remedy defaults in the payment of Rent, to
repair damage caused by Tenant, or to clean the Premises). Exercise by Landlord
of its rights hereunder shall not constitute a waiver of, or relieve Tenant from
any liability for, any default. If Tenant performs all of Tenant's obligations
hereunder, the Security Deposit, or so much thereof as has not theretofore been
applied by Landlord, shall be returned, without interest, to Tenant (or, at
Landlord's option, to the last assignee, if any, of Tenant's interest under this
Lease) within thirty (30) days after the later of (i) the date of expiration or
earlier termination of this Lease, or (ii) vacation of the Premises by Tenant if
the Premises has been left in the condition specified by this Lease. Landlord's
receipt and retention of the Security Deposit shall not create any trust or
fiduciary relationship between Landlord and Tenant and Landlord need not keep
the Security Deposit separate from its general accounts. Upon termination of the
original Landlord's (or any successor owner's) interest in the Premises, the
original Landlord (or such successor) shall be released from further liability
with respect to the Security Deposit upon the original Landlord's (or such
successor's) compliance with California Civil Code Section 1950.7(d), or
successor statute.

  27. Waiver. Failure of Landlord to declare a default by Tenant upon occurrence
thereof, or delay in taking any action in connection therewith, shall not waive
such default, but Landlord shall have the right to declare such default at any
time after its occurrence. To be effective, a waiver of any provision of this
Lease, or any default, shall be in writing and signed by the waiving party. Any
waiver hereunder shall not be deemed a waiver of subsequent performance of any
such provision or subsequent defaults. The subsequent acceptance of Rent
hereunder, or endorsement of any check by Landlord, shall not be deemed to
constitute an accord and satisfaction or a waiver of any preceding default by
Tenant, except as to the particular Rent so accepted, regardless of Landlord's
knowledge of the preceding default at the time of acceptance of the Rent. No
course of conduct between Landlord and Tenant, and no acceptance of the keys to
or possession of the Premises by Landlord before the Expiration Date shall
constitute a waiver of any provision of this Lease or of any default, or operate
as a surrender of this Lease.

  28. Notice and Consents; Tenant's Agent for Service. All notices, approvals,
consents, demands and other communications from one party to the other given
pursuant to this Lease shall be in writing and shall be made by personal
delivery, by use of a reputable overnight courier service or by deposit in the
United States mail, certified, registered or Express, postage prepaid and return
receipt requested. Notices shall be addressed if to Landlord, to Landlord's
Address, and if to Tenant, to Tenant's Address. Landlord and Tenant may each
change their respective Addresses from time to time by giving written notice to
the other of such change in accordance with the terms of this Article 28, at
least ten (10) days before such change is to be effected. Any notice given in
accordance with this Article 28 shall be deemed to have been given (i) on the
date of personal delivery or (ii) on the earlier of the date of delivery or
attempted delivery (as shown by the return receipt or other delivery record) if
sent by courier service or mailed.

  29. Tenant's Authority.  Tenant, and each of the persons executing this Lease
on behalf of Tenant, represent and warrant that (i) Tenant is a duly formed,
authorized and existing corporation, partnership or trust (as the case may be),
(ii) Tenant is qualified to do
<PAGE>

business in California, (iii) Tenant has the full right and authority to enter
into this Lease and to perform all of Tenant's obligations hereunder, and (iv)
each person signing on behalf of Tenant is authorized to do so. Tenant shall
deliver to Landlord, upon Landlord's request, such certificates, resolutions, or
other written assurances authorizing Tenant's execution and delivery of this
Lease, and such financial information regarding Tenant and its constituent
members, as requested by Landlord from time to time or at any time in order for
Landlord to assess Tenant's then authority and/or ability to meet its
obligations under this Lease.

  30. Automobile Parking.

    30.1. Tenant Appurtenant Parking Rights. Subject to the terms and conditions
contained in this Article 30, Landlord shall make available to Tenant parking
spaces in the parking areas designated by Landlord for parking in the
Marketplace (such areas being hereinafter collectively referred to as the
"Parking Facility"). For purposes of this Lease, the term "Minimum Spaces" shall
mean an amount equal to four (4) parking space for each 1,000 square feet of
Rentable Area leased by Tenant in the Building. Tenant shall at all times
provide to Landlord, upon Landlord's request, a list of all of the vehicle
makes, colors and license plate numbers of all vehicles of Tenant's employees.
Tenant's use of the parking spaces to be made available to Tenant shall be on a
non-exclusive basis in common with other tenants in the Marketplace; and parking
in such spaces shall be on a first-come-first-served, unassigned, non-reserved
basis. The parking spaces to be made available to Tenant shall be in locations
designated by Landlord; and Landlord reserves the right to designate different
locations from time to time without any liability to Tenant and Tenant agrees
that any such designation of a different location shall not give rise to any
claims or offset against Landlord hereunder. Without limiting the generality of
the foregoing, Landlord may restrict certain portions of the Parking Facility
for the exclusive use of one or more tenants of the Marketplace (and their
employees and agents) and may designate other areas in the Parking Facility to
be used at large only by licensees, customers and invitees of tenants of the
Marketplace; and Landlord may in its sole and absolute discretion restrict or
prohibit the use of the Parking Facility by any vehicles other than passenger
automobiles such as full-sized vans or trucks. Notwithstanding the foregoing,
Landlord shall not exercise any of the foregoing rights in a manner which would
permanently reduce the total number of parking spaces available to Tenant on a
non-exclusive basis to a number less than the Minimum Spaces. Tenant shall not
permit any vehicles belonging to Tenant or any of Tenant's subtenants or any of
their respective employees, agents, customers, contractors or invitees to be
loaded, unloaded or parked in areas other than those designated by Landlord for
such activities. In its use of the Parking Facilities Tenant shall comply (and
shall cause each of its subtenants and each of their respective employees,
agents, customers, contractors and invitees to comply) with any and all parking
regulations and rules established from time to time by Landlord or Landlord's
parking operator.  Landlord or Landlord's parking operator shall have the right
to cause to be removed any vehicles of Tenant, its subtenants or any of their
respective employees, agents, licesees, customers or invitees, that are parked
in violation of any of the provisions of this Article 30 or of the regulations
and rules then established by Landlord, and to charge all of the costs incurred
by Landlord in connection with such removal to Tenant and Tenant shall pay the
amount of all such costs to Landlord as additional rent within five (5) days
after receipt of written demand from Landlord. Any such removal shall be without
liability of any kind to Landlord or Landlord's parking operator or their
respective employees or agents; and Tenant shall protect, defend, indemnify and
hold Landlord and Landlord's parking operator and their respective employees and
agents from and against any and all claims, losses, damages, demands, costs and
expenses (including reasonable attorneys' fees) which may be asserted against or
incurred by any of such indemnified parties arising out of or in connection with
such removal of any automobiles.

    30.2. Parking Fee. During the initial Term, Landlord shall impose no charge
on Tenant for use of the Parking Facility. After the expiration of the initial
Term, Landlord shall have the right to impose on Tenant a charge for the use of
the Parking Facility. If Landlord imposes any such parking fee (the "Base
Parking Fee") after the expiration of the initial Term, then on the first day of
each and every calendar month thereafter, Tenant shall pay to Landlord the Base
Parking Fee for each parking space utilized by employees of Tenant or its
subtenants. If Tenant shall fail to pay the Base Parking Fee to Landlord as and
when required, Tenant shall have no further right to utilize the parking spaces
for which Tenant shall have failed to pay the Base Parking Fee. Landlord
reserves the right to separately charge Tenant's guests and visitors for
parking.  Landlord or Landlord's parking operator shall have the right from time
to time to adjust the amount of the Base Parking Fee to the then-prevailing fair
market rate as reasonably determined by Landlord or its parking operator.  Any
such adjustment shall be effective as of the first day of the first calendar
month following Tenant's receipt of such adjustment from Landlord. If any
governmental authority having jurisdiction charges Landlord a fee for parking
during the Term, Landlord shall have the right to include as Operating Expenses
such parking fees.

    30.3. Allocation of Risk. Landlord shall have no obligation to monitor the
use of the Parking Facility. The use of the Parking Facility by the employees of
Tenant and its subtenants shall be at the sole risk of Tenant, its subtenants
and their respective employees. Unless caused by the sole active gross
negligence or willful misconduct of Landlord, Landlord shall have no
responsibility or liability for any injury or damage to any person or property
by or as a result of the use of the Parking Facility by Tenant and its
subtenants and their respective employees, whether by theft, collision, criminal
activity, or otherwise; and Tenant hereby assumes, for itself, its subtenants
and their respective employees, all risks associated with any such occurrences
in or about the Parking Facility.

  31. Tenant to Furnish Financial Statements. In order to induce Landlord to
enter into this Lease, Tenant agrees that it shall promptly deliver to Landlord,
from time to time, upon Landlord's written request, financial statements
(including a balance sheet and statement of income and expenses on an annualized
basis) reflecting Tenant's then current financial condition. Such statements
shall be delivered to Landlord within fifteen (15) days after Tenant's receipt
of Landlord's request. Tenant represents and warrants that all financial
statements, records, and information furnished by Tenant to Landlord in
connection with this Lease are and shall be true, correct and complete in all
respects.

  32. Tenant's Signs. Without Landlord's prior consent, which Landlord may
withhold in its sole discretion, Tenant shall not place on the Premises or on
the Building any exterior signs nor any interior signs that are visible from the
exterior of the Premises or Building. Tenant shall pay all costs and expenses
relating to any such sign approved by Landlord, including without limitation,
the cost of the installation and maintenance of the sign. On the date of
expiration or earlier termination of this Lease, Tenant, at its sole cost and
expense, shall remove all signs and repair any damage caused by such removal.

  33. Miscellaneous.
<PAGE>

    33.1. No Joint Venture. This Lease does not create any partnership or joint
venture or similar relationship between Landlord and Tenant.

    33.2. Successors and Assigns. Subject to the provisions of Article 17
regarding assignment, all of the provisions, terms, covenants and conditions
contained in this Lease shall bind, and inure to the benefit of, the parties and
their respective successors and assigns.

    33.3. Construction and Interpretation. The words "Landlord" and "Tenant"
include the plural as well as the singular. If there is more than one person
comprising Tenant, the obligations under this Lease imposed on Tenant are joint
and several. References to a party or parties refers to Landlord or Tenant, or
both, as the context may require. The captions preceding the Articles, Sections
and subsections of this Lease are inserted solely for convenience of reference
and shall have no effect upon, and shall be disregarded in connection with the
construction and interpretation of this Lease. Use in this Lease of the words
"including", "such as", or words of similar import when following a general
manner, shall not be construed to limit such matter to the enumerated items or
matters whether or not language of nonlimitation (such as "without limitation")
is used with reference thereto. All provisions of this Lease have been
negotiated at arm's length between the parties and after advice by counsel and
other representatives chosen by each party and the parties are fully informed
with respect thereto. Therefore, this Lease shall not be construed for or
against either party by reason of the authorship or alleged authorship of any
provision hereof, or by reason of the status of the parties as Landlord or
Tenant, and the provisions of this Lease and the Exhibits hereto shall be
construed as a whole according to their common meaning in order to effectuate
the intent of the parties under the terms of this Lease.

    33.4. Severability. If any provision of this Lease, or the application
thereof to any person or circumstance, is determined to be illegal, invalid or
unenforceable, the remainder of this Lease, or its application to persons or
circumstances other than those as to which it is illegal, invalid or
unenforceable, shall not be affected thereby and shall remain in full force and
effect, unless enforcement of this Lease as so invalidated would be unreasonable
or grossly inequitable under the circumstances, or would frustrate the purposes
of this Lease.

    33.5. Entire Agreement; Amendments. This Lease, together with the Exhibits
hereto and any Addenda identified on the Basic Lease Information, contains all
the representations and the entire agreement between the parties with respect to
the subject matter hereof and any prior negotiations, correspondence, memoranda,
agreements, representations or warranties are replaced in total by this Lease,
the Exhibits hereto and such Addenda. Neither Landlord nor Landlord's agents
have made any warranties or representations with respect to the Premises or any
other portion of the Marketplace, except as expressly set forth in this Lease.
This Lease may be modified or amended only by an agreement in writing signed by
both parties.

    33.6. Governing Law. This Lease shall be governed by and construed pursuant
to the laws of the State of California.

    33.7. Litigation Expenses. If either party brings any action or proceeding
against the other (including any cross-complaint, counterclaim or third party
claim) to enforce or interpret this Lease or otherwise arising out of this
Lease, the prevailing party in such action or proceeding shall be entitled to
its costs and expenses of suit, including reasonable attorneys' fees and
accountants' fees.

    33.8. Standards of Performance and Approvals. Unless otherwise provided in
this Lease, (i) each party shall act in a reasonable manner in exercising or
undertaking its rights, duties and obligations under this Lease and (ii)
whenever approval, consent or satisfaction (collectively, an "approval") is
required of a party pursuant to this Lease or an Exhibit hereto, such approval
shall not be unreasonably withheld or delayed. Unless provision is made for a
specific time period, approval (or disapproval) shall be given within thirty
(30) days after receipt of the request for approval. Nothing contained in this
Lease shall, however, limit the right of a party to act or exercise its business
judgement in a subjective manner with respect to any matter as to which it has
been (A) specifically granted such right, (B) granted the right to act in its
sole discretion or sole judgment, or (C) granted the right to make a subjective
judgment hereunder, whether "objectively" reasonable under the circumstances and
any such exercise shall not be deemed inconsistent with any covenant of good
faith and fair dealing implied by law to be part of this Lease. The parties have
set forth in this Lease their entire understanding with respect to the terms,
covenants, conditions and standards pursuant to which their obligations are to
be judged and their performance measured, including the provisions of Article 17
with respect to assignments and sublettings.

    33.9.  Brokers. Landlord shall pay to Landlord's Broker and Tenant's Broker
as specified in the Basic Lease Information of this Lease, a commission in
connection with each Broker's negotiation of this Lease pursuant to a separate
agreement or agreements between Landlord and such Broker. Other than such
Brokers, Landlord and Tenant each represent and warrant to the other that no
broker, agent, or finder has procured or was involved in the negotiation of this
Lease and no such broker, agent or finder is or may be entitled to a commission
or compensation in connection with this Lease. Landlord and Tenant shall each
indemnify, defend, protect
<PAGE>

and hold the other harmless from and against any and all liability, loss,
damages, claims costs and expenses (including reasonable attorneys' fees)
resulting from claims that may be asserted against the indemnified party in
breach of the foregoing warranty and representation.

    33.10. Memorandum of Lease. Tenant shall, upon request of Landlord, execute,
acknowledge and deliver a short form memorandum of this Lease (and any amendment
hereto) in form suitable for recording. In no event shall this Lease or any
memorandum thereof be recorded by Tenant.

    33.11. Quiet Enjoyment. Upon paying the Rent and performing all its
obligations under this Lease, Tenant may peacefully and quietly enjoy the
Premises during the Term as against all persons or entities claiming by or
through Landlord, subject, however, to the provisions of this Lease any
encumbrances as specified in Article 21.

    33.12. Surrender of Premises. Upon the Expiration Date or earlier
termination of this Lease, Tenant shall quietly and peacefully surrender the
Premises to Landlord in the condition specified in Article 9 above. On or before
the Expiration Date or earlier termination of this Lease, Tenant shall remove
all of its personal property from the Premises and repair at its cost and
expense all damage to the Premises or Marketplace caused by such removal. All
personal property of Tenant not removed hereunder shall be deemed, at Landlord's
option, to be abandoned by Tenant and Landlord may store such property in
Tenant's name at Tenant's expense and/or dispose of the same in any manner
permitted by law.

    33.13. Name of Building Address. Tenant shall not use the name of the
Building or Marketplace for any purpose other than as the address of the
business conducted by Tenant in the Premises. Tenant shall, in connection with
all correspondence, mail or deliveries made to or from the Premises, use the
official Building address specified from time to time by Landlord.

    33.14. Exhibits. The Exhibits specified in the Basic Lease Information are
by this reference made a part hereof.

    33.15. Time of the Essence. Time is of the essence of this Lease and of the
performance of each of the provisions contained in this Lease.

  IN WITNESS WHEREOF, the parties have executed this Lease as of the Lease Date.

                          JOINT DEVELOPMENT AGREEMENT
                                BASE AGREEMENT

          THIS BASE AGREEMENT, dated as of August 12, 1999, is made by and
among Global Health Initiatives, a _________ corporation having offices in
Potomac, Maryland ("GHI"), Windom Health Enterprises, a California corporation
having offices in Berkeley, California ("Windom"), and HealthCentral.com, a

("HealthCentral.com").

          WHEREAS, the parties wish from time to time to enter into agreements
covering various projects that may be undertaken from time to time by the
parties involving:

          1)             services provided by GHI to Windom, HealthCentral.com
             or their customers;

          2)             services provided by Windom or HealthCentral.com to GHI
             or GHI's customers;

          3)             products provided by GHI to Windom or HealthCentral.com
             that are used to create jointly owned products; and

          4)             products provided by Windom or HealthCentral.com to GHI
             that are used to create jointly owned products.

          WHEREAS, the parties wish to specify the general terms and conditions
of such agreements by establishing this Base Agreement which may be incorporated
by reference into specific Project Agreements to be entered into from time to
time by the parties.

          NOW, THEREFORE, and in consideration of the mutual covenants herein
set forth and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

1.   A specific project will be defined in its own Project Agreement. The basic
     format for a Project Agreement is attached hereto as Annex A. Each Project
                                                          -------
     Agreement together with this Base Agreement forms a separate agreement,
     although the parties may refer to this Base Agreement together with all of
     its Project Agreements collectively as the Joint Development Agreement (the
     "JDA"). Only projects specified in a Project Agreement shall be subject to
     the JDA. The projects specified on Annex B shall not be subject to the JDA,
                                        -------
     rather they may be pursued individually (and not jointly) by the party as
     indicated on such Annex.

2.   The parties shall use their best efforts to perform the services, deliver
     the products or otherwise perform the obligations as specified in the
     Project Agreement.

3.   Unless otherwise specified in the Project Agreement for a particular
     project, (a) whenever a project principally involves one party acting as a
     sales agent for another party, the sales agent is entitled to a commission
     payable out of the project revenue in an amount equal to 10% of
<PAGE>

     the total project revenue and (b) whenever one party acts as a project
     manager for another party, the project manager is entitled to a fee payable
     out of the project revenue of 25% of the total project revenue.

4.   The JDA is a non-exclusive worldwide product and service agreement.

5.   The parties are acting as independent contractors and not as partners under
     the JDA.

6.   GHI's areas of service expertise will include (a) high level solution
     consulting; (b) integration and sales of integrated health care-specific
     enterprise engineering sales; (c) integration, sales and project management
     of next generation health information systems; and (d) development, sales
     and support of virtual health management services (e.g., demand management,
     disease management and population health services).

7.   GHI's products will include large scale domestic and international health
     information systems spanning clinical, administrative, telemedicine,
     educational, personal health, community network and population database
     systems.

8.   Windom's and HealthCentral.com's products will include personal and
     community health information systems.

9.   In the provision of services or products specified in each Project
     Agreement, (a) GHI may partner with other firms, as it deems appropriate,
     including in the areas of providing personal and community health
     information systems, and (b) Windom or HealthCentral.com may partner with
     other firms, as it deems appropriate, including in the areas of providing
     clinical, administrative, telemedicine, educational and population database
     information systems.

10.  The parties will continue to individually own any of their respective
     assets that they may make available to each other pursuant to the JDA. The
     parties will jointly own any products jointly produced as specified in the
     Project Agreement.

11.  Each party is entitled to a reasonable accounting of all revenue generated
     by a project that is the subject of a Project Agreement. Such revenue may
     only be used (a) to maintain operations and marketing for such project, (b)
     as specified in the applicable Project Budget, or (c) in a manner that is
     mutually agreed by the parties hereto.

12.  Each party will use its best efforts to develop a reasonable formula for
     sharing revenue from any co-branded assets and related services that may be
     developed or provided by the parties pursuant to the JDA.

13.  A Project Agreement must be executed by GHI, Windom and HealthCentral.com
     and may be executed by other persons or entities mutually acceptable to
     GHI, Windom and HealthCentral.com that wish to participate in the provision
     of products, licenses or services pursuant to the JDA, including
     distribution companies (e.g., international Internet providers) and content
     companies (e.g., Healthwise). Any party signing a Project Agreement agrees
     to

                                      -2-
<PAGE>

     be bound by all of the terms and conditions of this Base Agreement as
     if, and to the same extent that, such party were a party to this Base
     Agreement.

14.  Each party acknowledges that by reason of its relationship to the other
     hereunder it will have access to certain information and materials
     concerning the other parties' operations, business, plans, customers,
     technology and products that are confidential and of substantial value to
     such party, which value would be impaired if such information were
     disclosed to third parties. Each party agrees that it will not use in any
     way for its own account or the account of any third party, nor disclose to
     any third party, any information received by it which is marked
     confidential or which is disclosed orally and the confidential nature of
     which is confirmed in writing within 30 days after disclosure by the other
     party, and a written summary is provided by the disclosing party to the
     receiving party ("Confidential Information"). Each party shall protect the
     confidential nature of such Confidential Information with at least the
     level of care it takes to protect its own confidential information of
     similar value, but in no event with less than reasonable care. No party
     shall publish any Confidential Information of another party without that
     other party's written permission. In the event of termination of the JDA
     (or any part thereof), there shall be no use or disclosure by any party of
     any Confidential Information of another party.

15.  No party may assign its rights, duties or obligations under the JDA
     (whether by operation of law or otherwise) without the prior written
     consent of the other parties hereto, except that Windom's rights, duties
     and obligations may be assigned by operation of law to a wholly-owned
     subsidiary of HealthCentral.com pursuant to the currently contemplated
     merger.

16.  GHI shall not compete with Windom or HealthCentral.com in the area of
     public or institutional Consumer Heath Informatics product and service
     development. GHI will as a result receive "most favored customer" pricing
     at least as favorable as the pricing given to any other customer of Windom
     or HealthCentral.com purchasing similar or lesser quantities over similar
     or greater periods under substantially similar terms and conditions from
     Windom or HealthCentral.com on projects in which it is seeking to include
     consumer health informatics into its projects. To reciprocate GHI will
     grant Windom and HealthCentral.com first right of refusal on equal or
     better quality and with most favored customer pricing proposals on consumer
     health informatics development and service within GHI projects.

17.  Windom and HealthCentral.com shall not compete with GHI in the areas of (1)
     health care systems consulting, (2) enterprise engineering, (3) health
     information systems or (4) virtual health management, except, in the case
     of each of clauses (1) through (4) in this paragraph above, with respect to
     consumer health informatics. HealthCentral.com will as a result receive
     most favored customer pricing from GHI on projects in which it is seeking
     to include system consulting, enterprise engineering, broad health
     information systems development or virtual health management into its
     projects. To reciprocate HealthCentral.com and Windom will grant GHI first
     right of refusal on equal or better quality and most favored customer
     pricing proposals on consumer health informatics development and service
     within HealthCentral.com and Windom projects.

                                      -3-

18.  Notwithstanding Section 17 above, the JDA shall not restrict
     HealthCentral.com's ability to (1) provide personal health record products
     and services (including disease and demand management products and
     services) within virtual health management systems, or (2) enter into
     contracts or other arrangements (including investments and joint business
     development) with health information systems vendors. HealthCentral.com may
     also engage in providing linkages between personal health records held by
     the consumer, on the one hand, and clinical records, lab reports, radiology
     reports, and other types of reports generated or used by health
     professionals (including doctors and health care institutions), on the
     other hand.

19.  As used herein, "virtual health management" means the provision of health
     services through an information intense health network. Virtual health
     management systems may include traditional health and medical services, but
     they tend to focus on demand management, disease management and population
     health services in an integrated model of service delivery. The informed
     and empowered consumer is key to virtual health management. Effective
     interactive media and health information infrastructure are essential pre-
     requisites to virtual health management.

20.  The JDA shall terminate on the later of (a) the 5th anniversary of the date
     of the last Project Agreement, (b) the 2nd anniversary of completion or
     mutual abandonment of the last project undertaken hereunder, or (c) if no
     Project Agreement is ever executed and delivered by the parties, on or
     before the 5th anniversary of the date of this Base Agreement.

21.  The JDA shall be governed by and construed in accordance with the laws of
     the State of California (without regard to its choice of law principles).

22.  The JDA may be executed in counterparts, each of which constitute an
     original and all of which together constitute one and the same instrument.

23.  This Base Agreement, together with its Annexes including any Project
     Agreements attached hereto, constitute the entire agreement between the
     parties hereto concerning the subject matter hereof and supercede all prior
     oral or written agreements, arrangements and discussions with respect to
     such subject matter.

24.  If any provision in the JDA is determined to be invalid, void or
     unenforceable, in any respect, the remaining provisions of the JDA other
     than those held to be invalid, void or unenforceable, shall remain in full
     force and effect and in no way be affected, impaired or invalidated
     thereby, so long as the economic or legal substance of the transactions
     contemplated by the JDA is not affected in any manner adverse to any party.

                                      -4-

Agreement as "Confidential Information", provided, however, that after the
initial press release issued pursuant to the condition of paragraph 13.1 of this
Agreement, either party may disclose the existence of this Agreement and, in
general, the relationship between the Graedon Parties and HealthCentral.

          7.2 Ownership.

(iii) any Intellectual Property Rights to both of the foregoing.

     8.   Termination.
          -----------

          8.1  Term.
               ----

          (a)  Initial Term. This Agreement will become effective as of the
Effective Date and, unless sooner terminated as provided below, or as otherwise

Shares (the "Remaining Option Shares") shall vest (i) at the rate of 1/48/th/

Common Stock (i) to be issued in exchange for all outstanding shares of common
stock of the Company ("Company Common Stock") and (ii) reserved for issuance
                       --------------------
pursuant to options to acquire Company Common Stock ("Company Stock Options")
                                                      ---------------------
assumed in the Merger shall be 1,269,231 shares, as appropriately adjusted to
reflect the effect of any stock split, reverse stock split, stock dividend or
the like with respect to the Buyer Common Stock occurring after the date
hereof and prior to the Effective Time (the "Merger Share Number").
                                             -------------------

          (b)  Conversion of Company Common Stock.  Subject to the terms and
               ----------------------------------
conditions of this Agreement and the Certificate of Merger as of the Effective
Time, by virtue of the Merger and without any action on the part of the holder
of any shares of Company Common Stock, at the Effective Time, each share of
Company Common Stock issued and outstanding immediately prior to the Effective
Time (other than shares to be canceled pursuant to Section 1.6(d)) shall be
converted into the right to receive, subject to the provisions of Section
1.6(e) and Section 1.11 that number of shares of Buyer Common Stock determined
by dividing (i) the Merger Share Number less the Excess Expense Shares (as
defined in Section 5.7), if any (ii) by the Aggregate Company Shares (the
"Common Exchange Ratio"). The "Aggregate Company Shares" means the aggregate
 ---------------------         ------------------------
number of shares of Company Common Stock outstanding or issuable upon exercise
of outstanding Company Stock Options, whether or not exercisable, immediately
prior to the Effective Time. The aggregate number of shares of Buyer Common
Stock issued to the holders of Company Common Stock in the Merger are the
"Merger Shares."
 -------------

          (c)  No Conversion of Warrants or Other Rights to Purchase Company
               -------------------------------------------------------------
Common Stock.  Subject to Section 1.6(f), at the Effective Time, each warrant
- ------------
and other right to purchase Company Common Stock issued and outstanding
immediately prior to the Effective Time shall be exercised (to the extent such
warrant or right is exercisable at such time) or terminated.

          (d)  Cancellation of Company Common Stock Owned by Company.  At the
               -----------------------------------------------------
Effective Time, all shares of Company Common Stock that are owned by Company
as treasury

                                      -3-
<PAGE>

stock immediately prior to the Effective Time shall be canceled and
extinguished without any conversion thereof.

          (e)  Fractional Shares.  No fraction of a share of Buyer Common
               -----------------
Stock will be issued, but in lieu thereof each holder of shares of Company
Common Stock who would otherwise be entitled to a fraction of a share of Buyer
Common Stock (after aggregating all fractional shares of Buyer Common Stock to
be received by such holder) shall receive from Buyer such whole number of
shares of Buyer Common Stock as is equal to the precise number of shares of
Buyer Common Stock to which such person would be entitled, rounded up or down
to the nearest whole number (with a fractional interest equal to .5 rounded to
the next greater number).

          (f)  Company Stock Options.
               ---------------------

          (1)  At the Effective Time, all Company Stock Options then
outstanding under the ePills Inc. 1999 Stock Option Plan (the "Option Plan"),
                                                               -----------
whether vested or unvested, shall be assumed by Buyer in accordance with this
Section 1.6(f). Each Company Stock Option so assumed by Buyer at the Effective
Time will continue to have, and be subject to, the same terms and conditions
set forth in the Option Plan immediately prior to the Effective Time
(including, without limitation, any repurchase rights), except that (i) each
Company Stock Option will be exercisable (or will become exercisable in
accordance with its terms) for that number of whole shares of Buyer Common
Stock equal to the product of the number of shares of Company Common Stock
that were underlying such Company Stock Option immediately prior to the
Effective Time multiplied by the Common Exchange Ratio, rounded up or down to
the nearest whole number of shares of Buyer Common Stock (in accordance with
Section 1.6(e)), and (ii) the per share exercise price for the shares of Buyer
Common Stock issuable upon exercise of such assumed Company Stock Option will
be equal to the quotient determined by dividing the exercise price per share
of Company Common Stock at which such Company Stock Option was exercisable
immediately prior to the Effective Time by the Common Exchange Ratio, rounded
up or down to the nearest whole cent (in accordance with Section 1.6(e),
provided however that in the case of any Company Stock Option to which Section
422 of the Internal Revenue Code of 1986, as amended (the "Code") applies, the
                                                           ----
option price, the number of shares purchasable pursuant to such option and the
terms and conditions of exercise of such option shall be determined in order
to comply with Section 424(a) of the Code. In connection with the assumption
by Buyer of the Company Stock Options pursuant to this Section 1.6(f), Company
shall be deemed to have assigned to Buyer, effective at the Effective Time,
Company's right, if any, to repurchase unvested shares of Company Common Stock
issuable upon the exercise of the Company Stock Options or previously issued
upon the exercise of options granted under the Option Plan, in accordance with
the terms of the Option Plan and the related stock option agreements and stock
purchase agreements entered into under the Option Plan.

               (2)  As soon as practicable after the Effective Time, Company
and Buyer shall deliver to the participants in the Option Plan appropriate
notice setting forth such participants' rights pursuant thereto, that Buyer
has assumed all obligations of the Company under the Option Plan and that the
grants pursuant to the Option Plan shall continue in effect on

                                      -4-
<PAGE>

the same terms and conditions (subject to the adjustments required by this
Section 1.6 after giving effect to the Merger). Buyer shall comply with the
terms of the Option Plan and the parties intend that, to the extent required
by, and subject to the provisions of, such Option Plan and Sections 422 and
424(a) of the Code, that Options which qualified as incentive stock options
prior the Effective Time continue to qualify as incentive stock options after
the Effective Time, and this provision shall be interpreted consistent with
that intent. At or prior to the Effective Time, Buyer shall provide the
Company with evidence that it has taken all corporate action necessary to
reserve for issuance sufficient shares of Buyer Common Stock for delivery upon
exercise of Company Stock Options assumed by it in accordance with this
Section 1.6. As soon as practicable following the closing of an initial public
offering of the Company's Common Stock, Buyer shall file a registration
statement on Form S-8 (or any successor form) with respect to the assumed
Company Stock Options.

     1.7  Surrender of Certificates.
          -------------------------

          (a)  Buyer to Provide Merger Shares. Promptly after the Effective
               ------------------------------
Time, Buyer shall make available for exchange in accordance with this Article I,
through such reasonable procedures as Buyer may adopt, the shares of Buyer
Common Stock issuable pursuant to Section 1.6(b) in exchange for shares of
Company Common Stock outstanding immediately prior to the Effective Time, less
such number of shares of Buyer Common Stock as are to be deposited into an
escrow fund (the "Escrow Fund") pursuant to Section 1.11.   The portion of the
                  -----------
Escrow Fund contributed on behalf of each holder of Company Common Stock
immediately prior to the Effective Time (a "Company Stockholder") shall be in
                                            -------------------
proportion to the aggregate number of Merger Shares which such Company
Stockholder would otherwise be entitled to receive in the Merger by virtue of
such Company Stockholder's percentage ownership of outstanding shares of Company
Common Stock immediately prior to the Effective Time (the "Pro Rata Portion").
                                                           ----------------

          (b)  Exchange Procedures.  The Company will deliver to Buyer at
               -------------------
closing all certificates (the "Certificates") which immediately prior to the
                               ------------
Effective Time represented outstanding shares of Company Common Stock, whose
shares were converted into the right to receive Merger Shares pursuant to
Section 1.6, with duly and validly executed stock powers transferring such
Certificates to Merger Sub. Upon surrender of a Certificate for cancellation
to Buyer, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing the number of whole shares of
Buyer Common Stock which such holder has the right to receive pursuant to
Section 1.6 (less the number of shares of Buyer Common Stock to be deposited
in the Escrow Fund on such holder's behalf pursuant to Section 1.11 hereof)
and the Certificate so surrendered shall forthwith be canceled. Until so
surrendered, each outstanding Certificate that, prior to the Effective Time,
represented shares of Company Common Stock will be deemed from and after the
Effective Time, for all corporate purposes, other than the payment of
dividends, to evidence the ownership of the number of full shares of Buyer
Common Stock into which such shares of Company Capital Stock shall have been
so converted in accordance with Section 1.6. Buyer shall be responsible for
the payment of all transfer or other taxes required by reason of the issuance
of certificates for shares of Buyer Common Stock to Company Stockholders who
are United States residents.

                                      -5-
<PAGE>

          (c)  Transfers of Ownership.  If any certificate for shares of Buyer
               ----------------------
Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the
person requesting such exchange will have paid to Buyer any transfer or other
taxes required by reason of the issuance of a certificate for shares of Buyer
Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Buyer or any
agent designated by it that such tax has been paid or is not payable.

          (d)  No Liability.  Notwithstanding anything to the contrary in this
               ------------
Section 1.7, none of the Buyer, the Surviving Corporation or any party hereto
shall be liable to any person for any amount properly paid to a public
official pursuant to any applicable abandoned property, escheat or similar
law.

     1.8  No Further Ownership Rights in Company Common Stock.  The shares of
          ---------------------------------------------------
Buyer Common Stock issued upon the surrender for exchange of shares of Company
Common Stock in accordance with the terms hereof (together with the Escrow
Shares) shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Common Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation
of shares of Company Common Stock which were outstanding immediately prior to
the Effective Time. If, after the Effective Time, Certificates are presented
to the Surviving Corporation for any reason, they shall be canceled and
exchanged as provided in this Article I.

     1.9  No Change in Rights as a Result of Merger.  The Company has no
          -----------------------------------------
repurchase rights with regard to any shares of its capital stock outstanding.

     1.10 Tax Consequences.  It is intended by the parties hereto that the
          ----------------
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code and will be reported as such by the Company, the Buyer, the Surviving
Corporation and the Company Stockholders for all purposes.

     1.11 Escrow Agreement.  At the Effective Time or such later time as
          ----------------
determined in accordance with Section 1.12, Buyer will, on behalf of the Company
Stockholders deposit in escrow certificates representing ten percent (10%) of
the Merger Shares. Such shares shall be held in escrow on behalf of the Company
Stockholders in accordance with each holder's Pro Rata Portion. Such shares
(collectively, the "Escrow Shares") shall be held and applied pursuant to the
                    -------------
provisions of an escrow agreement (the "Escrow Agreement") to be executed
                                        ----------------
pursuant to Sections 6.2 and 6.3. The Escrow Agreement shall terminate six
months after the Closing, provided that if a notice of claim is given in
accordance with the Escrow Agreement before the expiration of such six month
period, an amount equal to any claimed amount which has not been resolved at
such termination date shall be retained in escrow until the resolution of such
claim.  All calculations to determine the number of Escrow Shares to be
delivered by each Company Stockholder into escrow as aforesaid shall be rounded
down to the nearest whole share.

     1.12 Dissenting Shares.
          -----------------

                                      -6-
<PAGE>

          (a)  Notwithstanding any provision of this Agreement to the
contrary, any shares of Company Common Stock held by a holder who has
exercised such holder's appraisal rights in accordance with Section 262 of
Delaware Law, and who, as of the Effective Time, has not effectively withdrawn
or lost such appraisal rights ("Dissenting Shares"), shall not be converted
                                -----------------
into or represent a right to receive Buyer Common Stock pursuant to Section
1.6, but the holder of the Dissenting Shares shall only be entitled to such
rights as are granted by Delaware Law.

          (b)  Notwithstanding the provisions of Section 1.12(a), if any
Company Stockholder who demands his appraisal rights with respect to such
shares under Section 1.12(a) shall effectively withdraw or lose (through
failure to perfect or otherwise) his rights to receive payment for such shares
under Delaware Law, then, as of the later of the Effective Time or the
occurrence of such event, such holder's shares shall automatically be
converted into and represent only the right to receive Buyer Common Stock upon
surrender of the Certificate or Certificates representing such shares;
provided that if such holder effectively withdraws or loses his right to
- --------
receive payment for such shares after the Effective Time, then, at such time
Buyer will deposit in the escrow created pursuant to the Escrow Agreement
additional Certificates representing such holder's Pro Rata Portion of the
Escrow Shares.

          (c)  The Company shall give Buyer (i) prompt notice of any written
demands for payment with respect to any shares of capital stock of the Company
pursuant to the appraisal rights under Delaware Law, withdrawals of such
demands, and any other instruments served pursuant to Delaware Law and
received by the Company and (ii) the opportunity to participate at its own
expense in all negotiations and proceedings with respect to demands for
appraisal rights under Delaware Law. The Company shall not, except with the
prior written consent of Buyer, voluntarily make any payment with respect to
any demands for appraisal rights with respect to Company Common Stock or offer
to settle or compromise any such demands.

the Escrow Shares and (ii) any other shares of Buyer Common Stock held by
Buyer stockholders who have the right to and elect to sell shares in such an
offering (the "Registrable Securities"), provided, however, that the Buyer

shall not be obligated to file any such

registration statement if Buyer shall furnish to the Stockholders' Agent a
certificate signed by the Chief Executive Officer of Buyer stating that, in
the good faith judgment of the Board of Directors or Chief Executive Officer
of Buyer, it would be seriously detrimental to Buyer and its stockholders for
the Resale S-1 Registration Statement to be filed on or before the date filing
would otherwise be required, and it is therefore in the best interests of
Buyer to defer the filing of the Resale S-1 Registration Statement, in which
case Buyer may delay the filing of the Resale S-1 Registration Statement not
in excess of forty-five (45) days after the original filing deadline.

               (3)  as soon as practicable, effect such registration and all
such qualifications and compliances as may be reasonably so requested and as
would permit and facilitate the sale and distribution of all or such portion
of such Holder's or Holders' Registrable Securities as are specified in such
request, together with all or such portion of the Registrable Securities of
any other Holder(s) and other Buyer stockholders joining in such request as
are specified in a written request given within ten (10) days after receipt of
such written notice from the Company; provided, however, that the Company
                                      --------  -------
shall not be obligated to cause any such registration, qualification or
compliance, pursuant to this Section 5.9 to become effective:

                    (i)   prior to the date six (6) months following the
effective date of the Buyer's initial public offering or later than the date
eleven (11) months after the Closing of the Merger.

                    (ii)  if the Holder(s), together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities at an aggregate price to the public of
less than $1,500,000; or

                    (iii) if the Company has already effected one (1)
registration for the Holder(s) pursuant to this Section 5.9.

          (b)  Requirement to Keep Effective.  The Buyer shall use its
               -----------------------------
reasonable best efforts to cause the Resale S-1 Registration Statement to
remain effective until the first to occur of (i) the one year anniversary of
the Closing Date of the Merger or (ii) the date by which all Registrable
Securities are sold.

          (c)  Expenses of Registration.  Buyer shall pay all Registration
               ------------------------
Expenses (as hereafter defined) in connection with any registration,
qualification or compliance pursuant to this Section 5.9, and each Holder
shall pay all Selling Expenses (as hereafter defined) and other expenses that
are not Registration Expenses relating to the Registrable Securities resold by
him or her. For purposes of this Section 5.9 "Registration Expenses" shall
                                              ---------------------
mean all expenses, except as otherwise stated below, incurred by Buyer in
complying with Sections 5.9(a), 5.9(b) and 5.9(d), including, without
limitation, all registration, qualification and filing fees, printing
expenses, escrow fees, fees and disbursements of counsel for Buyer, blue sky
fees and expenses and the expense of any special audits incident to or
required by any such registration and the reasonable fees and expenses of one
counsel for all of the selling Holders up to a maximum of $25,000. For
purposes of this Section 5.9(c), "Selling Expenses" shall mean all selling
                                  ----------------

                                      -35-
<PAGE>

discounts, commissions and stock transfer or other Taxes applicable to the
Registrable Securities and all fees and disbursements of counsel for any
Holder.

          (d)  Registration Procedures.  In the case of any registration
               -----------------------
effected by Buyer pursuant to this Section 5.9, Buyer will keep each Holder
advised in writing as to the initiation of each registration and as to the
completion thereof. Buyer will:

               (1)  Promptly prepare and file with the SEC such amendments and
supplements to the Registration Statement and the prospectus used in
connection with the Registration Statement as may be necessary to comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by the Registration Statement;

               (2)  Furnish such number of prospectuses (including preliminary
prospectuses) and other documents incident thereto, including any amendment of
or supplement to the prospectus, as a Holder from time to time may reasonably
request;

               (3)  Subject to Section 5.9(h) hereof, notify each Holder of
Registrable Securities covered by the Registration Statement at any time when
a prospectus relating thereto is required to be delivered under the Securities
Act of the happening of any event as a result of which the prospectus included
in the Registration Statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing, and at the request of any such
Holder, prepare and furnish to such Holder a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that,
as thereafter delivered to the purchasers of such shares, such prospectus
shall not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing;

               (4)  Cause all such Registrable Securities registered pursuant
to the Registration Statement to be listed on each securities exchange or
quotation system on which similar securities issued by Buyer are then listed
or quoted, and in connection therewith, file with the Nasdaq National Market
an application for listing of additional shares with respect to the
Registrable Securities;

               (5)  Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to the Registration Statement and a CUSIP
number for all such Registrable Securities, in each case not later than the
effective date of the Registration Statement;

               (6)  Use its reasonable best efforts to register or qualify the
Registrable Securities covered by the Registration Statement under such other
securities or blue sky laws of such jurisdiction within the United States and
Puerto Rico as shall be reasonably appropriate for the distribution of the
Registrable Securities covered by the Registration Statement; provided,
                                                              --------
however, that Buyer shall not be required in connection therewith or as a
- -------
condition thereto to qualify to do business in or file a general consent to
service of process in any jurisdiction wherein it would not but for the
requirements of this paragraph be obligated to do so; and

                                      -36-
<PAGE>

               (7)  Otherwise use its reasonable best efforts to comply with
all applicable rules and regulations of the SEC, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering a period of at least twelve months, but not more than eighteen
months, beginning with the first month after the effective date of the
Registration Statement, which earnings statement shall satisfy the provisions
of Section 11(a) of the Securities Act.

          (e)  Information by Holder.  Each Holder of Registrable Securities
               ---------------------
shall furnish to Buyer such information regarding such Holder and the
distribution proposed by such Holder as Buyer may reasonably request in
connection with any registration, qualification or compliance referred to in
this Section 5.9, but only to the extent that such information is required in
order for Buyer to comply with its obligations under all applicable securities
and other laws and to ensure that the Registration Statement relating to such
Registrable Securities conforms to the applicable requirements of the
Securities Act and the rules and regulations thereunder. Each Holder covenants
that it will promptly notify Buyer of any changes in the information set forth
in the Registration Statement or otherwise provided by such Holder to Buyer
regarding such Holder or such Holder's plan of distribution as a result of
which the Registration Statement or any prospectus relating to the Registrable
Securities contains or would contain an untrue statement of a material fact
regarding such Holder or its intended method of distribution of such
Registrable Securities or omits to state any material fact regarding such
Holder or its intended method of distribution of such Registrable Securities
required to be stated therein or necessary to make the statements therein, not
misleading.

          (f)  Indemnification and Contribution.
               --------------------------------

               (1)  Buyer agrees to indemnify and hold harmless each Holder
from and against any losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) to which such Holder may become subject (under
the Securities Act or otherwise) insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or
are based upon, any untrue statement, alleged untrue statement, omission or
alleged omission of a material fact in the Registration Statement, any
prospectus included in the Registration Statement, or any amendment or
supplement to the Registration Statement or any such prospectus, or any
violation or alleged violation by Buyer of the Securities Act, the Exchange
Act, any state law, rule or regulation promulgated thereunder, and Buyer will,
as incurred, reimburse such Holder for any legal or other expenses reasonably
incurred in investigating, defending or preparing to defend any such action,
proceeding or claim; provided, however, that the indemnity contained in this
Section 5.9(f)(1) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability, or action if such settlement is effected
without the consent of Buyer (which consent shall not be unreasonably
withheld), nor shall Buyer shall not be liable in any such case to the extent
that such loss, claim, damage or liability arises out of, or is based upon (A)
an untrue statement or alleged untrue statement made in such Registration
Statement in reliance upon and in conformity with written information
furnished to Buyer by such Holder in an instrument executed by such Holder and
specifically stated to be for use in the preparation of the Registration
Statement, (B) the failure of such Holder to comply with any of the covenants
and agreements contained in Sections 5.9(h) or 5.9(j) hereof, or (C)

                                      -37-
<PAGE>

any untrue statement in any prospectus that is corrected in any subsequent
prospectus that was delivered to the Holder prior to the pertinent sale or
sales by the Holder.

               (2)  Each Holder, severally and not jointly, agrees to
indemnify and hold harmless Buyer from and against any losses, claims, damages
or liabilities (or actions or proceedings in respect thereof) to which Buyer
may become subject (under the Securities Act or otherwise) insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) arise out of, or are based upon (A) an untrue statement, alleged
untrue statement, omission or alleged omission of a material fact in the
Registration Statement, any prospectus included in the Registration Statement,
or any amendment or supplement to the Registration Statement or any such
prospectus in reliance upon and in conformity with written information
furnished to Buyer by such Holder in an instrument executed by such Holder and
specifically stated to be for use in preparation of the Registration
Statement, or any violation or alleged violation by Holder of the Securities
Act, the Exchange Act, any state law, rule or regulation promulgated
thereunder, provided, however, the indemnity contained in this Section
5.9(f)(2) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability, or action if such settlement is effected without the
consent of Holder (which consent shall not be unreasonably withheld), and
provided that no Holder shall be liable in any such case for any untrue
statement included in any Prospectus which statement has been corrected in a
writing delivered to Buyer at least two business days before the sale from
which such loss arose, (B) the failure of such Holder to comply with any of
the covenants and agreements contained in Sections 5.9(h) or 5.9(j) hereof, or
(C) any untrue statement in any Prospectus that is corrected in any subsequent
Prospectus that was delivered to the Holder prior to the pertinent sale or
sales by the Holder; and each Holder, severally and not jointly, will, as
incurred, reimburse Buyer for any legal or other expenses reasonably incurred
in investigating, defending or preparing to defend any such action, proceeding
or claim. In no event shall the amount payable by any Holder to Buyer pursuant
to this Section 5.9(f) by reason of a sale of Buyer Common Stock by such
Holder exceed the amount of the net proceeds to such Holder from the sale of
Buyer Common Stock from which such liability arose.

               (3)  Promptly after receipt by any indemnified person under
subsections (1) or (2) above of a notice of a claim or the beginning of any
action in respect of which indemnity is to be sought against an indemnifying
person pursuant to this Section 5.9(f), such indemnified person shall notify
the indemnifying person in writing of such claim or of the commencement of
such action (provided, however, that no failure to provide such notice shall
relieve any indemnifying person of any liability hereunder except to the
extent that such indemnifying person is prejudiced thereby), and, subject to
the provisions hereinafter stated, in case any such action shall be brought
against an indemnified person and the indemnifying person shall have been
notified thereof, the indemnifying person shall be entitled to participate
therein, and, to the extent that it shall wish, to assume the defense thereof,
with counsel reasonably satisfactory to the indemnified person. After notice
from the indemnifying person to such indemnified person of the indemnifying
person's election to assume the defense thereof, the indemnifying person shall
not be liable to such indemnified person for any legal expenses subsequently
incurred by such indemnified person in connection with the defense thereof;
provided, however, that, if the indemnifying person shall propose that the
same counsel represent it and the indemnified person, and if counsel for the
indemnified person shall reasonably have

                                      -38-
<PAGE>

concluded that there is an actual conflict of interest posed by the
representation proposed by the indemnifying person, the indemnified person
shall be entitled to retain its own counsel reasonably satisfactory to the
indemnifying person at the expense of such indemnifying person; provided,
however that if more than one indemnified person makes a claim against an
indemnifying person based on substantially similar facts, the indemnifying
person shall not be responsible for the fees of more than one counsel for all
indemnified persons whose claims are based on substantially similar facts.

               (4)  If the indemnification provided for in this Section 5.9(f)
is unavailable to or insufficient to hold harmless an indemnified party under
subsection (1) or (2) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages
or liabilities (or actions in respect thereof), in such proportion as is
appropriate to reflect the relative fault of each such party, as well as any
other relevant equitable considerations, provided, however, that any
contribution by a Holder shall not exceed the net proceeds to such Holder for
the sale of Buyer Common Stock from which such liability arose, except in the
case of willful fraud by such Holder. The relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by Buyer on the one hand or a
Holder on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Buyer and the Holders agree that it would not be just and equitable if
contribution pursuant to this Section 5.9(f) were determined by any method of
allocation which does not take account of the equitable considerations
referred to above in this Section 5.9(f)(4). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, or liabilities
(or actions in respect thereof) referred to above in this Section 5.9(f)(4)
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action, proceeding or claim. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled
to contribution from any person who was not guilty of such fraudulent
misrepresentation.

               (5)  The obligations of the Buyer and the Holders under this
Section 5.9(f) shall be in addition to any liability which Buyer and the
respective Holders may otherwise have and shall extend, upon the same terms
and conditions, to each director and officer of Buyer or any Holder, and to
each person, if any, who controls Buyer or any Holder within the meaning of
the Securities Act or the Exchange Act.

          (g)  Restrictive Legend.  Each certificate representing Merger
               ------------------
Shares shall bear substantially the following legends (in addition to any
legends required under applicable securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT PURPOSES ONLY AND HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933. THE

                                      -39-
<PAGE>

     SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION
     OR AN EXEMPTION THEREFROM.

     ADDITIONALLY, THE TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE
     IS SUBJECT TO CERTAIN RESTRICTIONS SPECIFIED IN THE AGREEMENT AND PLAN OF
     REORGANIZATION AMONG THE ISSUER, HC2 ACQUISITION CORP., AND EPILLS INC.
     DATED ___________________, 1999 (THE "AGREEMENT"), WHICH INCLUDES AN
     OBLIGATION TO NOTIFY THE ISSUER PRIOR TO ANY SALE OR OTHER TRANSACTION,
     AND NO TRANSFER OF SHARES SHALL BE VALID OR EFFECTIVE ABSENT COMPLIANCE
     WITH SUCH RESTRICTIONS. ALL SUBSEQUENT HOLDERS OF THIS CERTIFICATE WILL
     HAVE AGREED TO BE BOUND BY CERTAIN OF THE TERMS OF THE AGREEMENT,
     INCLUDING SECTION 5.9 OF THE AGREEMENT. COPIES OF THE AGREEMENT MAY BE
     OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE REGISTERED HOLDER OF
     THIS CERTIFICATE TO THE SECRETARY OF THE ISSUER.

The legend contained in this Section 5.9(g) shall be removed from a certificate
in connection with any sale in compliance with the terms of this Agreement and
pursuant to the Resale S-1 Registration Statement, or pursuant to Rule 144 (if
accompanied by any legal opinion reasonably required by the Buyer), but shall
not be removed in any other circumstance without Buyer's prior written consent
(which consent shall not be unreasonably withheld or delayed and shall be
granted if such legend is no longer appropriate).

          (h)  Transfer of Shares After Registration.
               -------------------------------------

               (1)  Restriction.  No Holder may make any sale of any Merger
                    -----------
Shares except (A) in accordance with the Resale S-1 Registration Statement, in
which case Holder must comply with the requirement of delivering a current
prospectus, (B) in accordance with Rule 144, or (C) pursuant to an exemption
from the registration requirements of the Securities Act, if accompanied by an
opinion of counsel that registration is not necessary, which opinion and
counsel shall be reasonably satisfactory to Buyer.

               (2)  Notice to Buyer of Proposed Sale and Right of Buyer to
                    ------------------------------------------------------
Suspend Use of Registration Statement. If, at any time during the period after
- -------------------------------------
the Registration Statement has been declared effective and on or before the
date that is one year after the Closing of the Merger, any Holder shall
propose to sell any Registrable Securities pursuant to the Resale S1
Registration Statement, it shall submit written notice to the Buyer (a "Notice
                                                                        ------
of Sale") by facsimile transmission of such intention which shall include the
- -------
name of the Holder, the number of shares of Registrable Securities that such
holder intends to sell and the Holder's telephone and facsimile numbers. (If
the Notice of Sale is actually received on a day other than a business day, it
will be deemed received on the next business day; the date on which the Notice
of Sale is received is referred to as the "Notice Date;" the time on which the
                                           -----------
Notice of Sale is received is

                                      -40-
<PAGE>

referred to as the "Notice Time".) Upon receiving a Notice of Sale from a
                    -----------
Holder, the Buyer will notify the Holder as soon as reasonably practicable
(but in no event later than the same time as the Notice Time on the next
business day following the Notice Date) whether (i) the Buyer believes that
the prospectus contained in the Registration Statement, as then amended or
supplemented, is available for immediate use, whereupon the Buyer shall so
notify the Holder(s) and the Holder(s) will have a period of five (5) trading
days following such notification in which to sell its Registrable Securities
or (ii) the Buyer believes that it is necessary or appropriate to file a
supplement or file a post-effective amendment to the registration statement or
the prospectus or any document incorporated therein by reference or file any
other report or document so that, as thereafter delivered to the purchasers of
the Registrable Securities, the prospectus will not contain an untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein not misleading (a "Prospectus Update"). If the
                                               -----------------
Buyer notifies the Holder(s) that it believes it may be necessary or
appropriate to effectuate a Prospectus Update and the Buyer is not exercising
any right it may have under Section 5.9(i) to postpone the Prospectus Update,
the Buyer will thereupon use all reasonable efforts to effectuate such
Prospectus Update as soon as reasonably possible, and not later than three (3)
business days after the Notice of Sale is received by the Buyer, except that
the Buyer will have up to an additional two (2) business days to effectuate
such Prospectus Update if, because of the particular circumstances involved,
the Buyer could not effectuate the Prospectus Update earlier, despite all
reasonable diligence. As soon as the Prospectus Update has been effectuated,
the Buyer will notify each Holder who has submitted a Notice of Sale that the
prospectus is available for use, whereupon each such Holder will have a period
of five (5) trading days in which to sell its Registrable Securities.

          (i)  The Buyer will be entitled to postpone, for the minimum period
provided below, the filing of any Prospectus Update otherwise required to be
prepared and filed by it pursuant hereto if, at the time it receives a Notice
of Sale, the Buyer determines in its reasonable judgment, after consultation
with counsel, that (i) the Buyer would be required to prepare and file any
financial statements (other than those it customarily prepares or before it
customarily files such financial statements), (ii) the Buyer would be required
to file an amendment to the registration statement to describe facts or events
which individually or in the aggregate represent a fundamental change in the
information contained in the registration statement within the meaning of Item
512 of Regulation S-K promulgated under the Securities Act, or (iii) the
filing would require the premature announcement of any financing, acquisition,
corporate reorganization, contract or other material corporate transaction or
development involving the Buyer such as the Buyer reasonably determines would
be materially detrimental to the interests of the Buyer and its shareholders.
The postponement will be for the minimum period reasonably required for the
Buyer to prepare and file the necessary documents, in the case of a
postponement pursuant to (i) or (ii) above, or the minimum period reasonably
required to avoid such premature disclosure, in the case of (iii) above, and
which period will not be in excess of thirty (30) days unless, because of the
unusual nature of the particular circumstances, it is necessary that the
period extend beyond thirty (30) days. The Buyer will promptly give each
Holder who has submitted a Notice of

                                      -41-
<PAGE>

Sale notice of any postponement exercised pursuant to this Section 5.9(i). As
soon as the Prospectus Update has been effectuated following a postponement
effected pursuant to this Section 5.9(i), the Buyer will notify each Holder
who has submitted a Notice of Sale that the prospectus is available for use,
whereupon each such Holder will have a period of five (5) trading days in
which to sell its Registrable Securities.

          (j)  The Holder(s) may not sell shares of Registrable Securities
under this Section 5.9 without first (i) complying with the Notice of Sale
requirements of Section 5.9(h)(2) and (ii) allowing the Buyer to prepare
Prospectus Updates (including any permitted postponements thereof) as set
forth in Sections 5.9(h)(2) and 5.9(i). A Holder will submit a Notice of Sale
only if in good faith it actually intends to sell the Registrable Securities
within such five (5) trading day period and with the understanding that a
Notice of Sale is to be made only on the occasion that the sale of Registrable
Securities is actually contemplated and not on a continual basis. A Holder
will notify the Buyer by facsimile transmission promptly after it has
completed or otherwise ceased sales following submission of a Notice of Sale.
The Holder(s) will provide to the Buyer all information in the Holder(s)'
possession or control, and will take all actions, as may be required in order
to permit the Buyer to comply with all applicable requirements of the
Securities Act and any applicable state securities laws.

          (k)  Notwithstanding anything herein to the contrary, Buyer shall
keep a registration statement effective and available pursuant to this Section
5.9 for a minimum of thirty (30) days (after taking into account any periods
of delay permitted under Sections 5.9(h) and (i) above), shall permit the
Holders to sell the Merger Shares covered by such registration statement for a
minimum of thirty (30) days, and under no circumstances shall the Buyer be
required to keep a registration statement effective and available pursuant to
this Section 5.9 for greater than thirty (30) days (after taking into account
any periods of delay permitted under Sections 5.9(h) and (i) above).

          (l)  Rule 144 Reporting. With a view to making available the
               ------------------
benefits of certain rules and regulations of the SEC which may at any time
permit the sale of the Registrable Securities to the public without
registration, Buyer agrees to use its reasonable best efforts to:

               (1)  Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the Merger;

               (2)  File with the SEC in a timely manner all reports and other
documents required of Buyer under the Securities Act and the Exchange Act; and

               (3)  So long as a Holder owns any Registrable Securities, to
furnish to that Holder forthwith upon request a written statement by Buyer as
to its compliance with the reporting requirements of said Rule 144, and of the
Securities Act and the Exchange Act, a copy of the most recent annual or
quarterly report of Buyer, and such other reports and documents of Buyer as
such Holder may reasonably request in availing itself of any rule or
regulation of the SEC allowing such Holder to sell any such Registrable
Securities without registration.

including without limitation, attorneys' fees and costs, reasonably incurred
by the other party to the arbitration.

                           INDEMNIFICATION AGREEMENT
                           -------------------------


     This Indemnification Agreement (the "Agreement") is made as of ___________
                                          ---------
____, 1999, by and between HealthCentral.com, a Delaware corporation (the
"Company"), and <IndemniteeName> (the "Indemnitee").
 -------                               ----------

                                   RECITALS
                                   --------

     The Company and Indemnitee recognize the increasing difficulty in obtaining
liability insurance for directors, officers and key employees, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance.  The Company and Indemnitee further recognize the
substantial increase in corporate litigation in general, subjecting directors,
officers and key employees to expensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely limited.
Indemnitee does not regard the current protection available as adequate under
the present circumstances, and Indemnitee and agents of the Company may not be
willing to continue to serve as agents of the Company without additional
protection.  The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, and to indemnify its directors,
officers and key employees so as to provide them with the maximum protection
permitted by law.

                                   AGREEMENT
                                   ---------

     In consideration of the mutual promises made in this Agreement, and for
other good and valuable consideration, receipt of which is hereby acknowledged,
the Company and Indemnitee hereby agree as follows:

     1.   Indemnification.
          ---------------

          (a)  Third Party Proceedings.  The Company shall indemnify Indemnitee
               -----------------------
if Indemnitee is or was a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Company) by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company, or any subsidiary of the
Company, by reason of any action or inaction on the part of Indemnitee while an
officer or director or by reason of the fact that Indemnitee is or was serving
at the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) actually and reasonably incurred by
Indemnitee in connection with such action, suit or proceeding if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe Indemnitee's
conduct was unlawful.  The termination of any action, suit or proceeding by
judgment, order,
<PAGE>

settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that Indemnitee did not act in good
faith and in a manner which Indemnitee reasonably believed to be in or not
opposed to the best interests of the Company, or, with respect to any criminal
action or proceeding, that Indemnitee had reasonable cause to believe that
Indemnitee's conduct was unlawful.

          (b)  Proceedings By or in the Right of the Company.  The Company shall
               ---------------------------------------------
indemnify Indemnitee if Indemnitee was or is a party or is threatened to be made
a party to any threatened, pending or completed action or proceeding by or in
the right of the Company or any subsidiary of the Company to procure a judgment
in its favor by reason of the fact that Indemnitee is or was a director,
officer, employee or agent of the Company, or any subsidiary of the Company, by
reason of any action or inaction on the part of Indemnitee while an officer or
director or by reason of the fact that Indemnitee is or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) and, to the fullest extent permitted by
law, amounts paid in settlement (if such settlement is approved in advance by
the Company, which approval shall not be unreasonably withheld), in each case to
the extent actually and reasonably incurred by Indemnitee in connection with the
defense or settlement of such action or suit if Indemnitee acted in good faith
and in a manner Indemnitee reasonably believed to be in or not opposed to the
best interests of the Company and its stockholders, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which Indemnitee shall have been finally adjudicated by court order or judgment
to be liable to the Company in the performance of Indemnitee's duty to the
Company and its stockholders unless and only to the extent that the court in
which such action or proceeding is or was pending shall determine upon
application that, in view of all the circumstances of the case, Indemnitee is
fairly and reasonably entitled to indemnity for such expenses which such court
shall deem proper.

          (c)  Mandatory Payment of Expenses.  To the extent that Indemnitee has
               -----------------------------
been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Section 1(a) or Section 1(b) or the defense of any
claim, issue or matter therein, Indemnitee shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by Indemnitee in
connection therewith.

     2.   No Employment Rights.  Nothing contained in this Agreement is intended
          --------------------
to create in Indemnitee any right to continued employment.

     3.   Expenses; Indemnification Procedure.
          -----------------------------------

          (a)  Advancement of Expenses.  The Company shall advance all expenses
               -----------------------
incurred by Indemnitee in connection with the investigation, defense, settlement
or appeal of any civil or criminal action, suit or proceeding referred to in
Section l(a) or Section 1(b) hereof (including amounts actually paid in
settlement of any such action, suit or proceeding).  Indemnitee hereby
undertakes to repay such amounts advanced only if, and to the extent that, it
shall ultimately be determined that Indemnitee is not entitled to be indemnified
by the Company as authorized hereby.

                                      -2-
<PAGE>

          (b)  Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
               --------------------------------
condition precedent to his or her right to be indemnified under this Agreement,
give the Company notice in writing as soon as practicable of any claim made
against Indemnitee for which indemnification will or could be sought under this
Agreement.  Notice to the Company shall be directed to the Chief Executive
Officer of the Company and shall be given in accordance with the provisions of
Section 12(d) below.  In addition, Indemnitee shall give the Company such
information and cooperation as it may reasonably require and as shall be within
Indemnitee's power.

          (c)  Procedure.  Any indemnification and advances provided for in
               ---------
Section 1 and this Section 3 shall be made no later than twenty (20) days after
receipt of the written request of Indemnitee.  If a claim under this Agreement,
under any statute, or under any provision of the Company's Certificate of
Incorporation or Bylaws providing for indemnification, is not paid in full by
the Company within twenty (20) days after a written request for payment thereof
has first been received by the Company, Indemnitee may, but need not, at any
time thereafter bring an action against the Company to recover the unpaid amount
of the claim and, subject to Section 11 of this Agreement, Indemnitee shall also
be entitled to be paid for the expenses (including attorneys' fees) of bringing
such action.  It shall be a defense to any such action (other than an action
brought to enforce a claim for expenses incurred in connection with any action,
suit or proceeding in advance of its final disposition) that Indemnitee has not
met the standards of conduct which make it permissible under applicable law for
the Company to indemnify Indemnitee for the amount claimed, but the burden of
proving such defense shall be on the Company and Indemnitee shall be entitled to
receive interim payments of expenses pursuant to Section 3(a) unless and until
such defense may be finally adjudicated by court order or judgment from which no
further right of appeal exists.  It is the parties' intention that if the
Company contests Indemnitee's right to indemnification, the question of
Indemnitee's right to indemnification shall be for the court to decide, and
neither the failure of the Company (including its Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its stockholders) to have made a determination that indemnification of
Indemnitee is proper in the circumstances because Indemnitee has met the
applicable standard of conduct required by applicable law, nor an actual
determination by the Company (including its Board of Directors, any committee or
subgroup of the Board of Directors, independent legal counsel, or its
stockholders) that Indemnitee has not met such applicable standard of conduct,
shall create a presumption that Indemnitee has or has not met the applicable
standard of conduct.

          (d)  Notice to Insurers.  If, at the time of the receipt of a notice
               ------------------
of a claim pursuant to Section 3(b) hereof, the Company has director and officer
liability insurance in effect, the Company shall give prompt notice of the
commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies.  The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

          (e)  Selection of Counsel.  In the event the Company shall be
               --------------------
obligated under Section 3(a) hereof to pay the expenses of any proceeding
against Indemnitee, the Company, if appropriate, shall be entitled to assume the
defense of such proceeding, with counsel approved by Indemnitee, upon the
delivery to Indemnitee of written notice of its election so to do.  After

                                      -3-
<PAGE>

delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees of counsel subsequently incurred by
Indemnitee with respect to the same proceeding, provided that (i) Indemnitee
shall have the right to employ counsel in any such proceeding at Indemnitee's
expense; and (ii) if (A) the employment of counsel by Indemnitee has been
previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense or (C) the Company shall not, in
fact, have employed counsel to assume the defense of such proceeding, then the
fees and expenses of Indemnitee's counsel shall be at the expense of the
Company.

     4.   Additional Indemnification Rights; Nonexclusivity.
          -------------------------------------------------

          (a)  Scope.  Notwithstanding any other provision of this Agreement,
               -----
the Company hereby agrees to indemnify the Indemnitee to the fullest extent
permitted by law, notwithstanding that such indemnification is not specifically
authorized by the other provisions of this Agreement, the Company's Certificate
of Incorporation, the Company's Bylaws or by statute.  In the event of any
change, after the date of this Agreement, in any applicable law, statute, or
rule which expands the right of a Delaware corporation to indemnify a member of
its board of directors or an officer, such changes shall be deemed to be within
the purview of Indemnitee's rights and the Company's obligations under this
Agreement.  In the event of any change in any applicable law, statute or rule
which narrows the right of a Delaware corporation to indemnify a member of its
board of directors or an officer, such changes, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement shall have
no effect on this Agreement or the parties' rights and obligations hereunder.

          (b)  Nonexclusivity.  The indemnification provided by this Agreement
               --------------
shall not be deemed exclusive of any rights to which Indemnitee may be entitled
under the Company's Certificate of Incorporation, its Bylaws, any agreement, any
vote of stockholders or disinterested members of the Company's Board of
Directors, the General Corporation Law of the State of Delaware, or otherwise,
both as to action in Indemnitee's official capacity and as to action in another
capacity while holding such office.  The indemnification provided under this
Agreement shall continue as to Indemnitee for any action taken or not taken
while serving in an indemnified capacity even though he or she may have ceased
to serve in any such capacity at the time of any action, suit or other covered
proceeding.

     5.   Partial Indemnification.  If Indemnitee is entitled under any
          -----------------------
provision of this Agreement to indemnification by the Company for some or a
portion of the expenses, judgments, fines or penalties actually or reasonably
incurred in the investigation, defense, appeal or settlement of any civil or
criminal action, suit or proceeding, but not, however, for the total amount
thereof, the Company shall nevertheless indemnify Indemnitee for the portion of
such expenses, judgments, fines or penalties to which Indemnitee is entitled.

     6.   Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge
          ---------------------
that in certain instances, Federal law or public policy may override applicable
state law and prohibit the Company from indemnifying its directors and officers
under this Agreement or otherwise.  For example, the Company and Indemnitee
acknowledge that the Securities and Exchange

                                      -4-
<PAGE>

Commission (the "SEC") has taken the position that indemnification is not
                 ---
permissible for liabilities arising under certain federal securities laws, and
federal legislation prohibits indemnification for certain ERISA violations.
Indemnitee understands and acknowledges that the Company has undertaken or may
be required in the future to undertake with the SEC to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

     7.   Officer and Director Liability Insurance.  The Company shall, from
          ----------------------------------------
time to time, make the good faith determination whether or not it is practicable
for the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement. Among other
considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. In all policies of
director and officer liability insurance, Indemnitee shall be named as an
insured in such a manner as to provide Indemnitee the same rights and benefits
as are accorded to the most favorably insured of the Company's directors, if
Indemnitee is a director; or of the Company's officers, if Indemnitee is not a
director of the Company but is an officer; or of the Company's key employees, if
Indemnitee is not an officer or director but is a key employee. Notwithstanding
the foregoing, the Company shall have no obligation to obtain or maintain such
insurance if the Company determines in good faith that such insurance is not
reasonably available, if the premium costs for such insurance are
disproportionate to the amount of coverage provided, if the coverage provided by
such insurance is limited by exclusions so as to provide an insufficient
benefit, or if Indemnitee is covered by similar insurance maintained by a parent
or subsidiary of the Company.

     8.   Severability.  Nothing in this Agreement is intended to require or
          ------------
shall be construed as requiring the Company to do or fail to do any act in
violation of applicable law.  The Company's inability, pursuant to court order,
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement.  The provisions of this Agreement shall be severable as provided
in this Section 8.  If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

     9.   Exceptions.  Any other provision herein to the contrary
          ----------
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a)  Claims Initiated by Indemnitee.  To indemnify or advance expenses
               ------------------------------
to Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by Indemnitee and not by way of defense, except with respect to
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors finds it to be appropriate;

                                      -5-
<PAGE>

          (b)  Lack of Good Faith.  To indemnify Indemnitee for any expenses
               ------------------
incurred by Indemnitee with respect to any proceeding instituted by Indemnitee
to enforce or interpret this Agreement, if a court of competent jurisdiction
determines that each of the material assertions made by Indemnitee in such
proceeding was not made in good faith or was frivolous;

          (c)  Insured Claims.  To indemnify Indemnitee for expenses or
               --------------
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) to the
extent such expenses or liabilities have been paid directly to Indemnitee by an
insurance carrier under a policy of officers' and directors' liability insurance
maintained by the Company; or

          (d)  Claims under Section 16(b).  To indemnify Indemnitee for expenses
               --------------------------
or the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

     10.  Construction of Certain Phrases.
          -------------------------------

          (a)  For purposes of this Agreement, references to the "Company" shall
                                                                  -------
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, and employees or agents, so that
if Indemnitee is or was a director, officer, employee or agent of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, Indemnitee shall stand in
the same position under the provisions of this Agreement with respect to the
resulting or surviving corporation as Indemnitee would have with respect to such
constituent corporation if its separate existence had continued.

          (b)  For purposes of this Agreement, references to "other enterprises"
                                                              -----------------
shall include employee benefit plans; references to "fines" shall include any
                                                     -----
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
                   -------------------------------------
service as a director, officer, employee or agent of the Company which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants, or beneficiaries;
and if Indemnitee acted in good faith and in a manner Indemnitee reasonably
believed to be in the interest of the participants and beneficiaries of an
employee benefit plan, Indemnitee shall be deemed to have acted in a manner "not
                                                                             ---
opposed to the best interests of the Company" as referred to in this Agreement.
- --------------------------------------------

     11.  Attorneys' Fees.  In the event that any action is instituted by
          ---------------
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, the court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous.  In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this

                                      -6-
<PAGE>

Agreement, Indemnitee shall be entitled to be paid all court costs and expenses,
including attorneys' fees, incurred by Indemnitee in defense of such action
(including with respect to Indemnitee's counterclaims and cross-claims made in
such action), unless as a part of such action the court determines that each of
Indemnitee's material defenses to such action were made in bad faith or were
frivolous.

     12.  Miscellaneous.
          -------------

          (a)  Governing Law.  This Agreement and all acts and transactions
               -------------

Delaware, without giving effect to principles of conflict of law.

          (b)  Entire Agreement; Enforcement of Rights.  This Agreement sets
               ---------------------------------------

subject matter herein and merges all prior discussions between them.  No
modification of or 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.  The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party.

               ------------
between and has been reviewed by each of the parties hereto and their respective

against any one of the parties hereto.

          (d)  Notices.  Any notice, demand or request required or permitted to

          (g)  Subrogation.  In the event of payment under this Agreement, the
               -----------
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
to effectively bring suit to enforce such rights.
