                                  THE COMPANY

    HealthGate is an Internet provider of reliable, objective, comprehensive and
up-to-date healthcare information helping physicians and other healthcare
professionals, patients and health-conscious consumers make better informed
healthcare decisions. We have aggregated and developed what we believe are the
most extensive health and medical libraries of any online provider, currently
totaling approximately 27 million different pages of health and medical
information from approximately 300 sources representing 27 independent content
providers. In September 1999, our users viewed approximately 3.82 million
content pages on our own Web sites.

    Given the depth and breadth of our content, we provide healthcare
information to a wide range of online users. We facilitate user-friendly access
to our content libraries by segmenting them into collections for professionals,
patients and consumers. Content from any collection is available to any type of
user under a variety of pricing structures, including free access, per
transaction fee access and subscription. Our online library targeted to
physicians and other healthcare professionals includes internationally
recognized journals such as the NEW ENGLAND JOURNAL OF MEDICINE, bibliographic
databases such as MEDLINE, handbooks such as the Drug Information Handbook,
decision support materials such as the Poisoning and Toxicology Compendium and
Continuing Medical Education programs from the Boston University School of
Medicine and Professional Postgraduate Services. Our patient focused online
library includes patient education materials such as a series of over 3,000
patient education brochures published by the Clinical Reference Systems division
of Access Health. We have also created "Healthy Living" Webzines, a proprietary
series of consumer health magazines distributed exclusively through the Web, and
have produced Wellness Centers, which are compilations of selected information
from our online libraries for consumers, on 100 of the most prevalent illnesses,
diseases and medical conditions.

    We adapt and integrate this diverse content through our internally developed
software programs, which include our proprietary ReADER-Registered Trademark-
natural language searching software, designed to facilitate the search and
retrieval of relevant information in response to each user's searching needs. In
addition, our activePress-TM- service uses our technology to provide text
conversion and Web site development and hosting services for traditional print
publishers.

    We distribute our content through a network of proprietary and affiliated
Web sites that comprise the HealthGate Network. The HealthGate Network includes:

    - our own Web sites, www.healthgate.com and www.bewell.com in the United
      States and www.healthgate.co.uk in the United Kingdom;


    - customized, co-branded CHOICE-Registered Trademark- Web sites for
      institutions, principally hospitals, and businesses, which carry both
      HealthGate's and the entity's name, are designed as a seamless component
      of the entity's own Web site and, for certain institutions and businesses,
      complement the healthcare information, products and services they already
      offer or sell through their own Web sites; and



    - other co-branded third party Web sites to which we provide our proprietary
      and licensed content, including the Health Channel of www.snap.com for
      which we will be designated as an anchor tenant provider of health content
      following the completion of this offering.


                                       5
<PAGE>

    We have established marketing and distribution affiliations with Columbia
Information Systems, a subsidiary of Columbia/HCA Healthcare Corporation, GE
Medical Systems, the medical diagnostic equipment and services division of
General Electric Company and Data General Corporation, an information technology
and services company recently acquired by EMC Corporation. Columbia Information
Systems may provide up to 280 customized co-branded CHOICE Web sites to
hospitals and other health affiliates of Columbia/HCA Healthcare. GE Medical
Systems and Data General Corporation serve as value added resellers of versions
of our CHOICE Web product to their target hospital and health institution
customers.


    Subject specific Web sites dedicated to healthcare are one of the most
popular segments of the Internet. A July 1999 research report published by Cyber
Dialogue, Inc., an industry research firm, estimates that approximately
25 million adults in the United States search online for health and medical
information, a number which Cyber Dialogue projects will grow to approximately
30 million in 2000. We believe that with our extensive content libraries and
distribution network we are positioned to capture a leading share of the online
health audience as this industry continues to grow.

    Our strategy includes the following key elements:

    - providing leading healthcare content and technology;

    - expanding the HealthGate Network;

    - continuing to build the HealthGate brand;

    - broadening the range of offered products and services;

    - pursuing acquisitions and additional strategic affiliations; and

    - continuing to grow internationally.

    We currently generate revenue from the following activities:

    - syndicating content to third party Web sites;

    - providing our activePress Web publishing services to traditional print
      publishers;

    - offering banner advertising and sponsorship of discrete portions of our
      content libraries to pharmaceutical companies, other healthcare
      advertisers and other businesses and organizations;

    - participating in electronic commerce opportunities, also known as
      e-commerce, including selling articles from full-text journals, monthly
      online subscriptions and medical text books; and

    - developing co-branded CHOICE Web sites for hospitals and other
      institutions, and distributing content through these CHOICE Web sites.


    For the nine months ended September 30, 1999, the above activities generated
approximately 33%, 32%, 20%, 10% and 5%, respectively, of our total revenue.


    We are incorporated under the laws of the State of Delaware and our
executive offices are located at 25 Corporate Drive, Suite 310, Burlington,
Massachusetts 01803. Our telephone number is (781) 685-4000.

                                  RISK FACTORS


    An investment in our business involves significant risks. We urge you to
carefully read the section entitled "Risk Factors" beginning on page 10 of this
prospectus, which more fully describes the risks listed below and other risks
facing us, before making an investment decision.


    - Our business model is unproven, and we operate in the highly competitive
      and rapidly evolving Internet industry.


    - We have a history of significant losses. For the nine months ended
      September 30, 1999, we lost approximately $10.5 million and as of
      September 30, 1999, we had an accumulated deficit of approximately $29.3
      million. We also anticipate incurring losses, which may be substantial,
      for the foreseeable future.


    - We have received a report from our independent accountants containing an
      explanatory paragraph stating that our historical losses and negative cash
      flows from operations raise substantial doubt about our ability to
      continue as a going concern.

    - We must effectively manage the rapid growth of our business to be
      successful.

    - In June 1999 we received a letter from our independent accountants, which
      discussed a material weakness in our internal controls related to revenue
      recognition. This issue resulted in the restatement of our unaudited
      financial statements for the three months ended March 31, 1999. We have
      implemented additional financial and management controls and procedures to
      address this issue.

    YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW BEFORE MAKING AN
INVESTMENT DECISION. YOU SHOULD ALSO REFER TO THE OTHER INFORMATION IN THIS
PROSPECTUS, INCLUDING OUR FINANCIAL STATEMENTS AND THE RELATED NOTES. THE RISKS
AND UNCERTAINTIES DESCRIBED BELOW ARE THOSE THAT WE CURRENTLY BELIEVE MAY
MATERIALLY AFFECT OUR COMPANY. ADDITIONAL RISKS AND UNCERTAINTIES THAT WE ARE
UNAWARE OF OR THAT WE CURRENTLY DEEM IMMATERIAL ALSO MAY BECOME IMPORTANT
FACTORS THAT AFFECT OUR COMPANY.

    THIS PROSPECTUS ALSO CONTAINS FORWARD LOOKING STATEMENTS THAT INVOLVE RISKS
AND UNCERTAINTIES. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE
ANTICIPATED IN THESE FORWARD LOOKING STATEMENTS AS A RESULT OF CERTAIN FACTORS,
INCLUDING THE RISKS FACED BY US DESCRIBED BELOW AND ELSEWHERE IN THIS
PROSPECTUS.

                         RISKS RELATED TO OUR BUSINESS

WE HAVE A LIMITED OPERATING HISTORY AND HAVE RECENTLY INTRODUCED NEW SERVICES
WHICH MAKES AN EVALUATION OF OUR BUSINESS BASED ON PAST OPERATING RESULTS
DIFFICULT.

    We have been in business since February 1994, but we did not generate
revenue until January 1996. Through December 31, 1996, the majority of our
activities were related to development of products and services, exploration of
different sales and marketing channels, the build-up of hardware and software
infrastructure to support our www.healthgate.com Web site and the establishment
of the business, operations and financing of our company. Since 1997, we have
introduced new services and experienced significant growth in our operating
revenue relative to prior periods. Therefore, our historical financial
information is of limited value in evaluating our future operating results. An
investor in our common stock must consider the risks, expenses and difficulties
frequently encountered by companies in the early stages of development,
especially companies in a rapidly changing market like the market for Internet
services.

WE HAVE A HISTORY OF LOSSES, WE EXPECT THAT LOSSES WILL CONTINUE FOR THE
FORESEEABLE FUTURE AND OUR INDEPENDENT ACCOUNTANTS HAVE EXPRESSED SUBSTANTIAL
DOUBT ABOUT OUR ABILITY TO CONTINUE AS A GOING CONCERN.


    We have lost money in every period since we started our business and we had
an accumulated deficit of approximately $10.5 million as of December 31, 1998
and $29.3 million as of September 30, 1999. We plan to invest heavily to
continue to develop and expand our content libraries, to market our CHOICE Web
sites, to attract traffic to our Web sites at www.healthgate.com and
www.healthgate.co.uk, to increase our customer base, to upgrade our technology,
to expand internationally and to continue to build the HealthGate brand. As a
result, we expect to continue to lose money for the foreseeable future. We can
not assure you that we will ever achieve or sustain profitability or that our
operating losses will not increase in the future. We have received a report from
our independent accountants containing an explanatory paragraph stating that our
historical losses and negative cash flows from operations raise substantial
doubt about our ability to continue as a going concern. We will need to
successfully complete this offering or successfully execute our alternative
financing and operational plans to eliminate this uncertainty.


OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY WHICH MAY AFFECT THE
MARKET PRICE OF OUR COMMON STOCK IN A MANNER UNRELATED TO OUR LONG-TERM
PERFORMANCE.

    We expect our quarterly revenue, expenses and operating results to fluctuate
significantly in the future, which could affect the market price of our common
stock in a manner unrelated to our long-term operating performance. Quarterly
fluctuations could result from a number of factors, including:

    - the amount and timing of costs to expand our operations;

                                       10
<PAGE>
    - addition of new content providers or changes in our relationships with our
      most important content providers, which may require more expenditures in
      the early stages of these relationships;

    - the level of usage of the HealthGate Network which could impact, among
      other things, recognition of revenue in connection with advertising and
      sponsorship sales that are tied to the number of times advertisement or
      sponsorship banners are displayed to users;

    - seasonality of spending by the advertising industry, which is generally
      lower in the first and third calendar quarters; and

    - the amount and timing of expenses required to integrate operations and
      technologies from acquisitions, joint ventures or other business
      combinations or investments.

    We expect to increase the level of activity and spending in our operations,
particularly in sales and marketing and research and development. We base our
expense levels in part upon our expectations concerning future revenue and these
expense levels are predominantly fixed in the short-term. If we have lower
revenue than expected, we may not be able to reduce our spending in the
short-term in response. Any shortfall in revenue would have a direct impact on
our results of operations. In this event, the price of our common stock may
fall. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

NON-CASH EXPENSES RELATED TO RECENTLY ISSUED WARRANTS AND STOCK WILL ADVERSELY
AFFECT FUTURE OPERATING RESULTS.


    Beginning in the fiscal quarter ending June 30, 1999, we are amortizing as
an expense over a 12 month period the $10.3 million value of a warrant we issued
to General Electric Company in June 1999 in connection with our development and
distribution agreement with GE Medical Systems, a division of General Electric.
The value of this warrant was determined using the Black-Scholes option pricing
model. The value of this warrant may be adjusted on the effective dates of
certain events defined in this warrant should any of these events occur. In the
event the exercise price of this warrant is adjusted, its fair value will
increase. In addition, beginning in the fiscal quarter ending December 31, 1999,
we expect to begin amortizing as an expense over a three-year period the fair
value of a warrant that we issued to CIS Holdings Inc. in connection with our
marketing and reseller agreement with Columbia Information Systems. Based on the
currently anticipated range of the offering price for this offering, we expect
the fair value of this warrant to range from $10.7 million to $13.1 million,
calculated using the Black-Scholes option pricing model. In addition, beginning
in the fiscal quarter ending March 31, 2000, we expect to begin recognizing as
an expense over a one-year period the fair value of the common stock that we
issued to Snap in connection with our strategic alliance. The value of these
shares was $4.5 million at the time of issuance. Assuming the co-branded
Snap/HealthGate Web site is launched on March 1, 2000 and no adjustment is made
to the fair value of the GE Medical Systems warrant, we expect the total
non-cash expense associated with these recently issued warrants and the common
stock issued to Snap to range from $12.1 million to $12.9 million for fiscal
2000. The non-cash expenses associated with these warrants and the common stock
issued to Snap will have an adverse effect on our operating results and may
cause the market price of our common stock to fall. See "Business--Strategic
Affiliations and Relationships--Marketing and Distribution."


OUR BUSINESS PROSPECTS WILL SUFFER IF WE ARE NOT ABLE TO SUCCESSFULLY BUILD
RECOGNITION FOR THE HEALTHGATE BRAND.

    We believe that increasing awareness of the HealthGate brand is important to
our ability to attract additional users, customers, advertisers, sponsors and
strategic partners. We believe the importance of brand recognition will increase
in the future as the number of Web sites providing healthcare information
products and services increases. We plan to allocate significant resources to
develop and build brand recognition by expanding the reach of the HealthGate
Network, primarily through

                                       11
<PAGE>
increasing the number of CHOICE Web sites, promoting these CHOICE Web sites and
our own Web sites and through our alliance with Snap and Xoom. However, we can
not assure you that our efforts to build brand awareness will be successful.

OUR AGREEMENT WITH SNAP REQUIRES A SIGNIFICANT OUTLAY OF CASH AND THE SUCCESS OF
OUR BUSINESS WILL DEPEND IN PART ON THE SUCCESS OF OUR STRATEGIC ALLIANCE WITH
SNAP.


    We have agreed to pay Snap a minimum of $10.3 million for the first twelve
months of our strategic alliance and a minimum of $15.0 million in each of the
following two years to promote our name, our www.healthgate.com Web site, our
co-branded CHOICE Web sites and our other products and services. We have also
agreed to pay Snap up to an additional $5.0 million in the first year,
$10.0 million in the second year and $15.0 million in the third year of the
agreement if Snap delivers more than a minimum number of click-throughs to the
co-branded Snap/HealthGate Web site in the respective years. If our strategic
alliance with Snap does not lead to a significant increase in our sales of
advertising and sponsorship and in sales of products and services offered
through the co-branded Snap/HealthGate Web site and throughout the HealthGate
Network, our business, results of operations and financial condition may be
materially, adversely affected. In addition, if our strategic alliance with Snap
is terminated by Snap for a material breach by us, we have agreed to pay Snap
55% of the fees due to Snap under the agreement for the remaining term of the
agreement, which could also have a material adverse effect on our business,
results of operations and financial condition.


WE FACE INTENSE COMPETITION IN PROVIDING OUR INTERNET-BASED HEALTHCARE
INFORMATION PRODUCTS AND SERVICES AND WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY.

    The market for Internet services and products is relatively new, intensely
competitive and rapidly changing. Since the Internet's commercialization in the
early 1990s, the number of Web sites on the Internet competing for users'
attention has proliferated with no substantial barriers to entry. There are more
than 15,000 Web sites offering users healthcare content, products and services,
and we expect that competition will continue to grow. With low barriers to entry
in a relatively new and rapidly evolving industry, the types of entities against
which we compete, directly and indirectly, for subscribers, consumers, content
and service providers, advertisers, sponsors and acquisition candidates is
broad. Presently, our competitors include the following types of companies:

    - publishers and distributors of traditional print media targeted to
      healthcare professionals, patients and health-conscious consumers, many of
      which have established or may establish their own Web sites;

    - large healthcare information systems companies, such as McKesson HBOC and
      Shared Medical Systems;


    - online services or Web sites targeted to the healthcare industry
      generally, such as Healtheon/ WebMD, Medscape, Inteli-health, OnHealth and
      drkoop.com;


    - public sector and non-profit Web sites that provide healthcare information
      without advertising or commercial sponsorships, such as the National
      Library of Medicine and the American Medical Association;

    - Web sites, such as Yahoo!, America Online and Lycos, which provide access
      to healthcare related information and services; and

    - vendors of healthcare information, products and services distributed
      through other means, including direct sales, mail and fax messaging.

    Many of our competitors enjoy significant competitive advantages including:
greater resources that can be devoted to the development, promotion and sale of
their products and services; longer operating histories; greater brand
recognition; and larger customer bases.

                                       12
<PAGE>
    We also compete with other Web sites, traditional print media and other
sources of healthcare information for a share of total advertising budgets. If
advertisers perceive the Internet or the HealthGate Network to be limited or
ineffective advertising media, they may be reluctant to devote a portion of
their advertising budget to Internet advertising or to advertising on the
HealthGate Network. See "Business--Competition."

OUR BUSINESS IS EXPANDING RAPIDLY AND OUR BUSINESS PROSPECTS MAY SUFFER IF WE
ARE NOT ABLE TO EFFECTIVELY MANAGE THE GROWTH OF OUR OPERATIONS AND SUCCESSFULLY
INTEGRATE RECENT ADDITIONS TO OUR SENIOR MANAGEMENT TEAM.


    Since we began our business in 1994, we have significantly expanded our
operations over a short period of time. We have grown from three employees at
the end of 1994 to 88 full-time employees as of October 31, 1999, and we expect
to add a significant number of additional personnel in the near future. Several
members of our senior management joined us in 1999, including Mary B. Miller,
our Chief Financial Officer, and Richard J. Fecher, our Vice President of Sales.
We believe the successful integration of our senior management will be critical
to our ability to effectively manage our growth. Our rapid growth has placed a
substantial strain on our management, operational and financial resources and
systems. Our future success will depend in large part on our ability to
implement, improve and effectively utilize our operational, management,
marketing and financial resources and systems and train and manage our
employees. We can not guarantee that our management team will be able to
effectively manage the growth of our operations or that our systems, procedures
and controls will be adequate to support our expanding operations.


WE HAVE HAD TO RESTATE OUR FINANCIAL STATEMENTS FOR THE FIRST QUARTER OF 1999
AND IF WE ARE NOT ABLE TO MONITOR AND FOLLOW OUR NEWLY IMPLEMENTED INTERNAL
CONTROLS, OUR BUSINESS PROSPECTS AND THE PRICE OF OUR COMMON STOCK MAY SUFFER.

    On June 30, 1999, we received a letter from our independent accountants
which discussed a material weakness in our internal controls related to revenue
recognition. This material weakness resulted in the restatement of our unaudited
financial statements for the three months ended March 31, 1999 to reverse
$82,000 of revenue, as discussed in the "Management's Discussion and Analysis of
Financial Condition and Results of Operations" section. The letter emphasized
the need for a clearly defined, formal revenue accounting model for the
contracts underlying each type of transaction that generates revenue for us. In
addition, the letter emphasized the need for ongoing and proper communication
among our financial, operational and sales personnel and between us and our
independent accountants regarding key terms and conditions relating to our
contractual relationships. We have implemented additional financial and
management policies and procedures which we believe will address these concerns.
These controls and procedures will require continued monitoring and updating as
our business continues to evolve. If we are unsuccessful in following or
monitoring these internal controls and procedures, we may not be able to
accurately report our financial condition or our results of operations. If we
are unable to accurately report financial information, we could be subject to,
among other things, fines, securities litigation and a general loss of investor
confidence, any one of which could adversely affect our business prospects and
the price of our common stock.

WE MAY NOT BE ABLE TO SUCCESSFULLY IMPLEMENT OUR GROWTH AND ACQUISITION
STRATEGY.

    Key elements of our growth strategy include making acquisitions of, or
significant investments in, complementary companies, products or technologies to
increase our content libraries, technological capabilities and customer base and
entering into other strategic affiliations. To date, we have not made any major
acquisitions or investments. For our acquisition strategy to be successful, we
will need to identify content sources, technologies and businesses that are
complementary to ours, integrate disparate technologies and corporate cultures
and possibly manage a geographically dispersed company. We may also lose key
employees while integrating any new companies. For these reasons, we may not

                                       13
<PAGE>
be successful in integrating any acquired businesses or technologies and may not
achieve anticipated revenue and cost benefits. Simultaneously pursuing
acquisitions, strategic affiliations and other elements of our growth strategy
could be expensive, time consuming and may strain our resources. If we are not
successful in implementing our growth and acquisition strategy, our business,
results of operations and the market price of our common stock could be
adversely affected.

    In addition, we may be required to amortize significant amounts of goodwill
and other intangible assets in connection with future acquisitions, which could
adversely affect our results of operations and the market price of our common
stock.

COMPETITION FOR HIGHLY-SKILLED PERSONNEL IS INTENSE AND THE SUCCESS OF OUR
BUSINESS DEPENDS ON OUR ABILITY TO ATTRACT AND RETAIN KEY PERSONNEL.

    Our performance depends on the continued services and performance of our
executive officers and key employees, including William S. Reece, our President,
Chief Executive Officer and Chairman of the Board, Mary B. Miller, our Chief
Financial Officer and Treasurer, Mark A. Israel, our Chief Technology Officer,
Richard J. Fecher, our Vice President of Sales, and Rick Lawson, our Vice
President of Content and Secretary. We maintain key person life insurance
payable to us on Mr. Reece in the amount of $1 million. We do not maintain key
person life insurance policies on any other officers or employees. Our future
success also depends on our ability to identify, attract, hire, train, retain
and motivate highly skilled technical, managerial, editorial, marketing and
customer service personnel. Competition for highly-skilled personnel is intense.
In particular, skilled technical employees are highly sought after in the Boston
area, and we can not guarantee that we will be able to attract or retain these
employees.

THE SUCCESS OF OUR BUSINESS WILL DEPEND ON OUR ABILITY TO SELL ADVERTISING ON
THE HEALTHGATE NETWORK.


    We derived approximately 20% of our revenue in the nine months ended
September 30, 1999 from the sale of general and targeted banner advertising,
including barter revenue, and sponsorships of discrete topic areas on the
HealthGate Network, compared to 28% of our revenue in the nine months ended
September 30, 1998 and 27% of our revenue in the year ended December 31, 1998.
In general, barter revenue has been decreasing as a percentage of revenue.
Barter advertising revenue was $73,000 or 4% of total revenue for the nine
months ended September 30, 1999 compared to $350,000 or 19% of total revenue for
the nine months ended September 30, 1998 and $436,000 or 18% of total revenue
for the year ended December 31, 1998. We anticipate that barter revenue will
continue to decrease as a percentage of total revenue in the future. Barter
revenue is not a source of cash available to fund our operations. Under our
sponsorship arrangements, a sponsor's name or a message selected by the sponsor
is included on each page of the topic area together with a click-through link to
the sponsor's Web site.


    Our future success depends on our ability to generate and increase revenue
from advertising and sponsorship which will depend on a number of factors,
including:

    - the development of the Internet as an advertising medium;

    - the amount of traffic on the HealthGate Network and the number of
      registered and unique users of our content; and

    - our ability to achieve and demonstrate registered and unique user
      demographic characteristics that are attractive to sponsors and
      advertisers.

    Most of our advertisements to date have been displayed on our own Web sites
and have been sold on the basis of the number of impressions, or times that an
advertisement appears in page views downloaded by users, rather than on the
number of click-throughs, or user requests for additional information made by
clicking on the advertisement. We can not guarantee that our advertising
customers will accept our internal and third party measurements of these
impressions received by advertisements on the HealthGate Network, or that these
measurements will be free from errors. If we

                                       14
<PAGE>
are unable to accurately measure these impressions or have our advertising
customers accept these measurements, advertisers may not be willing to buy
advertising space from us. In addition, there are currently a variety of pricing
models for selling advertising on the Internet. It is difficult to predict which
model, if any, will emerge as the industry standard. This uncertainty makes it
difficult to project our future advertising rates and revenue that we may
generate from advertising.

THE SUCCESS OF OUR BUSINESS WILL DEPEND ON OUR ABILITY TO SELL A SUBSTANTIAL
NUMBER OF CO-BRANDED CHOICE WEB SITES.

    A key element of our strategy is to expand the HealthGate Network by
establishing co-branded CHOICE Web sites. We commercially introduced our CHOICE
Web site product in early 1999 and as of September 30, 1999 had delivered 39
CHOICE Web sites to enterprise clients.


    Under our CHOICE Web site arrangements, we are paid a fee for developing,
implementing and hosting a CHOICE Web site for our customer. In addition, the
arrangements typically provide the opportunity for us to place third party
advertising and sponsorship on the customer's CHOICE Web site. We collect the
fees for this advertising and sponsorship from the third party and pay a
commission to the customer. However, as part of our agreements with 14 of our
initial CHOICE customers, we have guaranteed that we will pay minimum
advertising and sponsorship commissions to these customers in amounts
approximately equal to the fees paid to us by the customer for the initial term
of their CHOICE agreements and, in a few cases, in amounts that exceed those
fees. We are obligated to pay these guaranteed commissions to the customer,
generally on a quarterly basis, regardless of whether or not we have actually
sold any advertising or sponsorship on the CHOICE Web site. The initial terms of
these agreements generally range from one to three years. We have entered into
these types of arrangements for promotional purposes to establish our CHOICE Web
site product but have discontinued the use of these arrangements as a standard
practice. However, we can not assure you that we will not use this or a similar
type of promotion in the future.



    For those CHOICE Web sites for which we have guaranteed advertising and
sponsorship commissions, we do not recognize revenue unless the guaranteed
commissions are less than the fee for developing, implementing and hosting paid
to us. Any excess of fees paid to us over guaranteed commissions is recognized
as revenue ratably over the term of the agreement. If the advertising and
sponsorship commissions that we guarantee to the customer exceed the fees paid
to us, we recognize the excess as expense upon signing the agreement. As we sell
advertising or sponsorship on these CHOICE Web sites to third parties, we will
recognize advertising revenue from these CHOICE Web sites. For those CHOICE Web
sites for which we do not guarantee advertising and sponsorship commissions, we
recognize as revenue the fee paid to us by the customer ratably over the term of
the agreement. To date, we have sold advertising or sponsorship on only five
CHOICE Web sites, four of which are part of the initial 14 CHOICE Web sites for
which we have guaranteed to pay minimum advertising and sponsorship commissions.
We cannot guarantee that we will be successful in selling advertising or
sponsorship on these or additional sites in the future.


    Our CHOICE product is new and unproven and we can not assure you that we
will be able to sell additional CHOICE products without advertising and
sponsorship guarantees or without lowering the price of the product. Our CHOICE
product is an important part of our business model and if we are unable to sell
a substantial number of CHOICE Web sites, our business prospects, results of
operations and the market price of our common stock could be materially
adversely affected.

THE PERFORMANCE OF OUR WEB SITES AND COMPUTER SYSTEMS IS CRITICAL TO OUR
BUSINESS AND OUR BUSINESS WILL SUFFER IF WE EXPERIENCE SYSTEM FAILURES.

    The performance of our Web sites and computer systems is critical to our
reputation and ability to attract and retain users, customers, advertisers and
subscribers. We provide products and services based on sophisticated computer
and telecommunications software and systems, which often experience development
delays and may contain undetected errors or failures when introduced into our
existing

                                       15
<PAGE>
systems. Although we have only experienced one minor unscheduled service
interruption of approximately four hours since the beginning of 1998, we can not
guarantee that we will not experience more significant service interruptions in
the future. We are also dependent upon Web browsers and Internet service
providers to provide Internet users access to our Web sites. Many of them have
experienced significant outages in the past and could experience outages, delays
and other difficulties in the future due to system failures. For example, on
August 7, 1996, a major Internet service provider experienced a service outage
of over 20 hours. We also depend on certain information providers to deliver
information and data feeds to us on a timely basis. Our Web sites could
experience disruptions or interruptions in service due to the failure or delay
in the transmission or receipt of this information. System errors or failures
that cause a significant interruption, for example, 24 hours or more, in the
availability of our content or an increase in response time on our Web sites
could cause us to lose potential or existing users, customers, advertisers or
subscribers and could result in damage to our reputation and brand name or a
decline in our stock price.

    Given our reliance on our own and third party computer and
telecommunications software and systems, any of the following occurrences could
cause response time delays or system failures on our Web sites:

    - a sudden and significant increase in the number of users of our Web sites;

    - any failure or delay in the transmission or receipt of downloads from our
      content providers;

    - any disruption in our Internet access through our third party Internet
      service providers;

    - any failure of our third party Internet service providers to handle higher
      volumes of users; and

    - fire, hurricanes, power loss, break-ins, computer viruses and other events
      beyond our control.

    In March 1999, we entered into a one year Internet Data Center Services
Agreement with Exodus Communications, Inc. to house all of our central computer
facility servers at Exodus's Internet Data Center in Waltham, Massachusetts. We
do not presently maintain fully redundant systems at separate locations, so our
operations depend on Exodus's ability to protect the systems in its data center
against damage from fire, power loss, water damage, telecommunications failure,
vandalism and similar events. Although Exodus provides comprehensive facilities
management services, including human and technical monitoring of all production
servers, Exodus does not guarantee that our Internet access will be
uninterrupted, error-free or secure. We have also developed a disaster recovery
plan to respond to system failures. We can not guarantee that our disaster
recovery plan is capable of being implemented successfully, if at all. Finally,
we maintain property insurance for our equipment, but do not maintain business
interruption insurance. We can not guarantee that our insurance will be adequate
to compensate us for all losses that may occur as a result of any system
failure.

WE RETAIN CONFIDENTIAL CUSTOMER INFORMATION IN OUR DATABASE AND IF WE FAIL TO
PROTECT THIS INFORMATION AGAINST SECURITY BREACHES WE MAY LOSE CUSTOMERS.

    We retain confidential customer information in our database. Therefore, it
is critical that our facilities and infrastructure remain secure and that they
are perceived by consumers to be secure. Despite the implementation of security
measures, our infrastructure may be vulnerable to physical break-ins, computer
viruses, programming errors or similar disruptive problems. A material security
breach could damage our reputation or result in liability to us. We believe that
maintaining the trust of our customers is important for us to be able to grow
our business and, therefore, we believe that any damage to our reputation or
liability arising from one or more security breaches could adversely affect our
business, results of operations and the market price of our common stock.

                                       16
<PAGE>
WE MAY NEED ADDITIONAL CAPITAL IN THE FUTURE TO SUPPORT OUR GROWTH AND SUCH
ADDITIONAL FINANCING MAY NOT BE AVAILABLE TO US.

    We expect that the net proceeds from this offering, combined with our
current cash resources, will be sufficient to meet our requirements for at least
the next 12 months. However, as we continue our efforts to grow our business in
the rapidly changing and highly competitive market for Internet-based healthcare
products and services, we may need to raise additional financing to support
expansion, develop new or enhanced products and services, respond to competitive
pressures, acquire complementary businesses or technologies or take advantage of
unanticipated business opportunities. In addition, as a result of our recent
strategic alliance with Snap, we have substantial financial commitments to Snap
over the next three years. If this strategic alliance does not lead to a
significant increase in our sales of advertising and sponsorship and in sales of
products and services offered through the co-branded Snap/HealthGate Web site
and throughout the HealthGate Network, we may need to raise more capital sooner
than we had originally anticipated. We may need to raise additional funds by
selling debt or equity securities, by entering into strategic relationships or
through other arrangements. We may be unable to raise any additional amounts on
reasonable terms when they are needed. Any additional equity financing may cause
investors to experience dilution, and any additional debt financing may result
in restrictions on our operations or our ability to pay dividends in the future.

OUR BUSINESS PROSPECTS MAY SUFFER IF WE ARE NOT ABLE TO KEEP UP WITH THE RAPID
TECHNOLOGICAL DEVELOPMENTS IN THE INTERNET INDUSTRY.

    The Internet industry is characterized by rapid technological developments,
evolving industry standards, changes in user and customer requirements and
frequent new service and product introductions and enhancements. The
introduction of new technology or the emergence of new industry standards and
practices could render our systems and, in turn, our products and services,
obsolete and unmarketable or require us to make significant unanticipated
investments in research and development to upgrade our systems in order to
maintain the marketability of our products. To be successful, we must continue
to license or develop leading technology, enhance our existing products and
services and respond to emerging industry standards and practices on a timely
and cost-effective basis. If we are unable to successfully respond to these
developments, particularly in light of the rapid technological changes in the
Internet industry generally and the highly competitive market in which we
operate, our business, results of operations and the market price of our common
stock could be adversely affected.

THE YEAR 2000 PROBLEM COULD SIGNIFICANTLY DISRUPT OUR OPERATIONS, CAUSING A
DECLINE IN CASH FLOW AND REVENUE AND OTHER DIFFICULTIES.

    Many currently installed computer systems and software products are unable
to distinguish between twentieth century dates and twenty-first century dates.
As a result, many companies' software and computer systems may need to be
upgraded or replaced to comply with these Year 2000 requirements. Our business
is dependent on the operation of numerous systems that could potentially be
impacted by Year 2000 related problems.

    As of June 30, 1999, we have completed internal assessments of our Year 2000
readiness, with an emphasis on our operating and administrative systems and the
proprietary software systems and third party software and hardware we use to
deliver services to our customers, and are not aware of any Year 2000 problems
that could reasonably be expected to have a material adverse effect on our
business. Many of our vendors of material software, hardware and services have
indicated that the products we use are currently Year 2000 compliant. However,
we can not guarantee that we have identified or will identify all Year 2000
compliance problems in our infrastructure that may require substantial revisions
and fixes. Also, despite our testing and reviews, we may experience Year 2000
problems related to the third party software, hardware or other systems on which
we are reliant, and any of these problems may be time consuming or expensive to
fix.

                                       17
<PAGE>
    We believe that the most reasonably likely worst case scenario would result
in a prolonged Internet, telecommunications or electrical failure which would
affect our ability to meet our commitments to our customers or decrease the use
of the Internet, thus preventing our users from accessing our services. We have
given a warranty in our activePress agreements with Blackwell Science and our
CHOICE Web site agreement with Columbia Information Systems that our
applications and services are Year 2000 compliant. If our applications and
services fail to be Year 2000 compliant, these agreements could be terminated or
we could be liable for damages, either of which could have a material adverse
effect on our business. In addition, the purchasing patterns of customers or
potential customers may be affected by Year 2000 questions, and any significant
delays in purchasing decisions could also affect us. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Compliance Readiness Disclosure."

WE MAY BE SUBJECT TO LIABILITY FOR INFORMATION RETRIEVED FROM OUR WEB SITE.

    As a publisher and distributor of online information, we may be subject to
third party claims for defamation, negligence, copyright or trademark
infringement or other theories based on the nature and content of information
supplied on our Web sites. We could also become liable if confidential
information is disclosed inappropriately. These types of claims have been
brought, sometimes successfully, against online service providers in the past.
We could be subject to liability with respect to content that may be accessible
through our Web sites or third party Web sites linked from our Web sites. For
example, claims could be made against us if material deemed inappropriate for
viewing by children could be accessed through our Web sites or if a
professional, patient or consumer relies on healthcare information accessed
through our Web sites to their detriment. Even if any of the kinds of claims
described above do not result in liability to us, we could incur significant
costs in investigating and defending against them and in implementing measures
to reduce our exposure to this kind of liability. Our insurance may not cover
potential claims of this type or may not be adequate to cover all costs incurred
in defense of potential claims or to indemnify us for all liability that may be
imposed.

WE DEPEND ON OUR CONTENT PROVIDERS, AS THE SUCCESS OF OUR BUSINESS DEPENDS ON
OUR ABILITY TO PROVIDE A COMPREHENSIVE LIBRARY OF HEALTHCARE INFORMATION.

    With the exception of our Healthy Living series of Webzines, we license all
of our content from third parties. With a few exceptions, these licenses are
generally non-exclusive, have an initial term of one year and are renewable. In
addition, a significant number of these licenses permit cancellation by the
content provider upon 30 to 90 days notice. We can not guarantee that we will be
able to continue

to license our present content or sufficient additional content to provide a
diverse and comprehensive library. In the future, we may not be able to license
content at reasonable cost. In addition, one or more of our publishers or other
content providers may grant one of our competitors an exclusive arrangement with
respect to a significant database or periodical, or elect to compete directly
against us by making its content exclusively available through its own Web site.
Presently, we believe it would be difficult to replace the NEW ENGLAND JOURNAL
OF MEDICINE and the journals made available by Blackwell Science with other
journals of the same reputation. These sources are committed to us through April
2001 and December 2001, respectively, but if either of them chooses not to renew
the agreements they have with us, our business could be adversely affected
because the quality of our content is important in attracting online users,
advertisers and CHOICE customers.

WE RELY ON OUR WEB-BASED MAGAZINES TO INCREASE TRAFFIC ON OUR WEB SITES.

    A key element of our strategy involves our continued development of our
Healthy Living series of consumer oriented Webzines. Articles for our Webzines
are written by freelance medical writers who we engage to write specific
articles. If these medical writers and our editorial board are not successful in
producing articles for our Webzines that are topical, informative and timely, we
may fail to attract a significant number of users to our Web sites. Without
substantial traffic on our Web sites, we will be severely hindered in selling
advertising on our Web pages and in building the brand name recognition we
believe is necessary to be competitive.

                                       18

THE MAJORITY OF OUR REVENUE HAS HISTORICALLY BEEN DERIVED FROM A FEW CUSTOMERS
AND THE LOSS OF ANY OF THESE CUSTOMERS COULD ADVERSELY AFFECT OUR BUSINESS.


    Historically, we have generated a substantial portion of our revenue from a
few customers. For the nine months ended September 30, 1999, two customers,
Blackwell Science, one of our largest stockholders, and WebMD, accounted for
33%, and 12%, respectively, of our total revenue. For the year ended
December 31, 1998, Blackwell Science and WebMD accounted for 44% and 18%,
respectively of our total revenue. We expect to continue to generate a
substantial portion of our revenue in the near future from these customers and
the loss of any of them could adversely affect our business. Our agreements with
Blackwell Science run through December 2001. We are presently negotiating with
WebMD concerning the terms of the annual renewal of the agreement which was
contemplated for October 30, 1999. During our negotiations, we are continuing to
provide content to WebMD under the same terms as provided under our earlier
agreement. We can not assure you that we will be able to reach mutually
agreeable terms of renewal with WebMD, and, if we do not, we may lose WebMD as a
customer. Because WebMD represented 12% of our total revenue for the nine months
ended September 30, 1999, the loss of WebMD as a customer may have a material
adverse effect on our business and results of operations.



OUR RELATIONSHIP WITH BLACKWELL SCIENCE, GENERAL ELECTRIC AND COLUMBIA
INFORMATION SYSTEMS MAY GIVE RISE TO CONFLICTS OF INTEREST AND, ON A COMBINED
BASIS, THESE ENTITIES WILL BE ABLE TO EXERCISE SIGNIFICANT CONTROL OVER
HEALTHGATE.



    Blackwell Science and one of its affiliates will beneficially own
approximately 12.5% of our outstanding common stock after this offering and
Blackwell and another of its affiliates are our largest customer, accounting for
approximately 33% of our revenue for the nine months ended September 30, 1999
and 44% of our revenue for the year ended December 31, 1998. Because Blackwell
and its affiliates are significant customers and stockholders, our relationship
with them could give rise to conflicts of interest. In the event we attempt to
expand into Europe or Asia, we have agreed to negotiate in good faith with
Blackwell Science to determine in what manner Blackwell Science may serve as our
primary strategic alliance partner in connection with such expansion.



    Based on its current holdings, General Electric is expected to beneficially
own approximately 21.9% of our outstanding common stock after this offering,
including 1,189,800 shares issuable under a warrant. If the initial public
offering price is $10.00 and Snap purchases $5,000,000 (500,000 shares) of our
common stock for which it has expressed a non-binding interest, General Electric
is expected to beneficially own approximately 24.7% of our outstanding common
stock after this offering. Additionally, we have entered into a development and
distribution agreement with GE Medical Systems, an operating division of General
Electric, pursuant to which GE Medical Systems has an exclusive worldwide right
to sell GE Medical Systems branded enhanced CHOICE Web sites to hospitals and
other patient care facilities and the exclusive right to sell our standard
CHOICE Web site product to a select group of hospitals and other patient care
facilities. We have also entered into a strategic alliance with Snap, in which
NBC, a subsidiary of General Electric, owns a majority interest. Because General
Electric is both a strategic affiliate and stockholder, our relationship with
them could give rise to conflicts of interest.


    After this offering, Columbia/HCA Healthcare Corporation, through its
indirect, wholly-owned subsidiary CIS Holdings, Inc., will beneficially own
approximately 10.6% of our outstanding common stock, based on the 1,941,035
shares issuable under the warrant we issued to CIS Holdings. We have also
entered into a development agreement and a marketing and reseller agreement with
Columbia Information Systems, which is also an indirect wholly-owned subsidiary
of Columbia/HCA. Because Columbia/HCA is both a strategic affiliate and the
beneficial owner of a significant percentage of our stock, our relationship with
them could give rise to conflicts of interest.

                                       19
<PAGE>

    Blackwell Science, General Electric and Columbia/HCA may influence the terms
on which we do business with them in the future or the terms on which we do
business with other providers of healthcare products and services who compete
with them.



    Furthermore, after this offering Blackwell Science, General Electric and
Columbia/HCA, together with their respective affiliates, will beneficially own
approximately 42.6% of our common stock, including shares issuable under
warrants and assuming Snap purchases $5,000,000 (500,000 shares) of our common
stock at the estimated initial public offering price of $10.00, for which it has
expressed a non-binding interest. If these unaffiliated entities act together,
they will be able to significantly influence the management and affairs of
HealthGate and will have the ability to control most matters requiring
stockholder approval, including the election of directors and approval of
significant corporate transactions. This concentration of ownership may have the
effect of delaying, deferring or preventing an acquisition of HealthGate and may
adversely affect the market price of our common stock. See "Principal
Stockholders."


OUR BUSINESS MAY BE ADVERSELY AFFECTED IF WE ARE NOT ABLE TO EFFECTIVELY PROTECT
OUR INTELLECTUAL PROPERTY RIGHTS.


    We regard our trademarks, service marks, copyrights, trade secrets and
similar intellectual property as important to our business, and we rely upon
trademark and copyright law, trade secret protection and confidentiality and/or
license agreements with our employees, customers, strategic partners and others
to protect our rights in this property. We have registered our "HealthGate,"
"HealthGate Data," "CHOICE," "MedGate" and "ReADER" trademarks in the U.S. and
we have pending U.S. applications for our HealthGate logo and "activePress"
trademarks. Effective trademark, copyright and trade secret protection may not
be available in every country in which our products and services are distributed
or made available through the Internet. Therefore, we can not guarantee that the
steps we have taken to protect our proprietary rights will be adequate to
prevent infringement or misappropriation by third parties or will be adequate
under the laws of some foreign countries which may not protect HealthGate's
proprietary rights to the same extent as do the laws of the United States.


    It is possible that other businesses will adopt product or service names
similar to ours. This may hinder our ability to build brand identity and
possibly lead to customer confusion. In the future, we may have to litigate
against these businesses and others to enforce and protect our trademarks,
service marks, trade secrets, copyrights and other intellectual property rights.
Any enforcement litigation would divert management resources and be expensive
and may not effectively protect our intellectual property.


    Although we believe that our proprietary rights do not infringe on the
intellectual property rights of others, other parties may assert infringement
claims against us or claim that we have violated a patent or infringed a
copyright, trademark or other proprietary rights belonging to them. These
claims, even if they are without merit, could result in our spending a
significant amount of time and money to dispose of them. We received a letter
dated July 27, 1999 from TechSearch L.L.C. claiming ownership of a patent that
claims exclusive rights to all electronic methods of on-demand remote retrieval
of graphic and audiovisual information. The letter asserted that the use of our
Web site, www.healthgate.com, infringes the patent. In the letter, TechSearch
offered to license the patent perpetually and retroactively to us for a one-time
fee of between $50,000 and $150,000 depending upon the number of "hits" per day
on our web site. We are currently investigating this matter. At this time,
however we are unable to predict its outcome.



    We license almost all of our content from third parties. Under most of our
license agreements, the licensor has agreed to defend and indemnify us for
losses with respect to third-party claims that the licensed content infringes
third-party proprietary rights. However, we can not assure you that these
provisions will be adequate to protect us from infringement claims.


                                       20
<PAGE>
OUR BUSINESS MAY BE ADVERSELY AFFECTED IF WE ARE UNABLE TO CONTINUE TO LICENSE
SOFTWARE THAT IS NECESSARY FOR THE DEVELOPMENT OF PRODUCT AND SERVICE
ENHANCEMENTS.

    We rely on a variety of technologies that are licensed from third parties,
including our database software and Internet server software, which is used in
our Web sites to perform key functions. These third party licenses may not be
available to us on commercially reasonable terms in the future. The loss of or
inability to maintain any of these licenses could delay the introduction of
software enhancements, interactive tools and other features until equivalent
technology could be licensed or developed.

                         RISKS RELATED TO OUR INDUSTRY

OUR BUSINESS PROSPECTS DEPEND ON THE CONTINUED GROWTH IN USE OF THE INTERNET.

    We believe that our future success will require the continued development
and widespread acceptance of the Internet and online services as a medium for
obtaining and distributing healthcare and medical information. Internet use is
at an early stage of development and may be inhibited by a number of factors,
such as:

    - Internet infrastructure which is not able to support the demands placed on
      it, or its performance and reliability declining as usage increases;

    - security concerns with respect to transmission over the Internet of
      confidential information, such as credit card numbers;

    - privacy concerns; and

    - governmental regulation.

OUR BUSINESS PROSPECTS ARE UNCERTAIN, AS THE MARKET FOR ONLINE HEALTHCARE
INFORMATION AND SERVICES IS STILL DEVELOPING.

    The online healthcare information market is in the early stages of
development, is rapidly evolving and is characterized by an increasing number of
market entrants who have introduced competing products and services. As is
typical in the case of a new and rapidly evolving industry, demand and market
acceptance for recently introduced products and services are subject to a high
level of uncertainty and risk. Therefore, it is difficult to predict with any
assurance the size of the market for online healthcare information or its growth
rate. We can not guarantee that physicians, hospitals and other healthcare
providers and consumers will view obtaining healthcare information through the
Internet as an acceptable way to address their healthcare information needs.

OUR BUSINESS PROSPECTS DEPEND ON THE USE OF THE INTERNET AS AN ADVERTISING
MEDIUM.

    Most potential advertisers and their advertising agencies have only limited
experience with the Internet as an advertising medium and have not devoted a
significant portion of their advertising expenditures to Internet-based
advertising. Therefore, it is too early to know whether advertisers or
advertising agencies will be persuaded to allocate portions of their budgets to
Internet-based advertising or, if so persuaded, whether they will find
Internet-based advertising to be an effective means of promoting their products
and services relative to traditional print and broadcast media. Acceptance of
the Internet among advertisers and advertising agencies will depend, to a large
extent, on the level of use of the Internet by consumers and upon growth in the
commercial use of the Internet, neither of which has yet been proven.

    There is intense competition for advertising revenue on high-traffic Web
sites which has resulted in significant price competition. Currently, there are
a variety of pricing models for selling advertising on the Internet. Several of
the most popular pricing models are based on the number of impressions or

                                       21
<PAGE>
click-throughs, the duration over which an advertisement is displayed or the
number of keywords to which the advertisement will be linked. It is difficult to
predict which, if any, will emerge as the industry standard. This uncertainty
makes it difficult to project our future advertising rates and revenue that we
may generate from advertising. In addition, filter software programs that limit
or prevent advertising from being delivered to a Web users' computers are
available. It is unclear whether this type of software will become widely
accepted. However, if it does, it would negatively affect Internet-based
advertising, as advertisers will be less likely to advertise on the Internet if
they have no assurance they will reach their desired audience.

GOVERNMENT REGULATION OF THE INTERNET MAY RESULT IN INCREASED COSTS OF USING THE
INTERNET WHICH COULD ADVERSELY AFFECT OUR BUSINESS.

    Currently, there are a number of laws that regulate communications or
commerce on the Internet. Several telecommunications carriers have petitioned
the Federal Communications Commission to regulate Internet service providers and
online service providers in a manner similar to long distance telephone carriers
and to impose access fees on these providers. Regulation of this type, if
imposed, could substantially increase the cost of communicating on the Internet
and adversely affect our business, results of operations and the market price of
our common stock.

PRIVACY-RELATED REGULATION OF THE INTERNET COULD ADVERSELY AFFECT OUR BUSINESS.

    Internet user privacy has become an issue both in the United States and
abroad. The Federal Trade Commission and government agencies in some states and
countries have been investigating certain Internet companies regarding their use
of personal information. Any regulations imposed to protect the privacy of
Internet users may affect the way in which we currently collect and use personal
information.

    The European Union (EU) has adopted a directive that imposes restrictions on
the collection and use of personal data, guaranteeing citizens of EU member
states certain rights, including the right of access to their data, the right to
know where the data originated and the right to recourse in the event of
unlawful processing. We can not assure you that this directive will not
adversely affect our activities in EU member states.

    As is typical with most Web sites, our Web sites place certain information
(cookies) on a user's hard drive without the user's knowledge or consent. This
technology enables Web site operators to target specific users with a particular
advertisement and to limit the frequency with which a user is shown a particular
advertisement. Some currently available Internet browsers allow users to modify
their browser settings to remove cookies at any time or to prevent cookies from
being stored on their hard drives. In addition, some Internet commentators,
privacy advocates and governmental bodies have suggested limiting or eliminating
the use of cookies. If this technology is reduced or limited, the Internet may
become less attractive to advertisers and sponsors.

    A feature of our own Web sites includes the retention of personal
information about our users. We have a stringent privacy policy covering this
information. However, if third parties were able to penetrate our network
security and gain access to, or otherwise misappropriate, our users' personal
information, we could be subject to liability. Such 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. We could incur additional expenses
if new regulations regarding the use of personal information are introduced or
if any regulator chooses to investigate our privacy practices.

                                       22
<PAGE>
TAX TREATMENT OF COMPANIES ENGAGED IN INTERNET COMMERCE MAY ADVERSELY AFFECT THE
INTERNET INDUSTRY AND OUR COMPANY.

    Tax authorities on the federal, state, and local levels are currently
reviewing the appropriate tax treatment of companies engaged in Internet
commerce. New state tax regulations may subject us to additional state sales,
income and other taxes. A recently passed federal law places a temporary
moratorium on certain types of taxation on Internet commerce. We can not predict
the effect of current attempts at taxing or regulating commerce over the
Internet. It is also possible that the governments of other states and foreign
countries also might attempt to regulate our transmission of content on our Web
sites and throughout the rest of the HealthGate Network. Any new legislation,
regulation or application or interpretation of existing laws would likely
increase our cost of doing business and may adversely affect our results of
operations and the market price of our common stock.

WE MAY BE SUBJECT TO LIABILITY FOR CLAIMS THAT THE DISTRIBUTION OF MEDICAL
INFORMATION TO CONSUMERS CONSTITUTES PRACTICING MEDICINE OVER THE INTERNET.

    States and other licensing and accrediting authorities prohibit the
unlicensed practice of medicine. We do not believe that our publication and
distribution of healthcare information online constitutes practicing medicine.
However, we can not guarantee that one or more states or other governmental
bodies will not assert claims contrary to our belief. Any claims of this nature
could result in our spending a significant amount of time and money to defend
and dispose of them.

                         RISKS RELATED TO THIS OFFERING

BECAUSE WE ARE AN INTERNET BASED COMPANY, OUR COMMON STOCK PRICE MAY BE VOLATILE
AND YOU MAY NOT BE ABLE TO SELL YOUR SHARES AT OR ABOVE THE INITIAL PUBLIC
OFFERING PRICE.

    The stock market in general, and the market for technology and Internet
related companies in particular, has experienced extreme price and volume
fluctuations, in particular over the last 12 months. These broad market and
industry fluctuations may adversely affect the market price of our common stock,
regardless of our actual operating performance. The initial public offering
price for the shares of our common stock 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 market. You may not be able to resell your
shares at or above the initial public offering price due to a number of factors,
including:

    - changes in the market valuations of other Internet or online service
      companies;

    - actual or anticipated quarterly fluctuations in our operating results;

    - changes in expectations of future financial performance or changes in
      estimates of securities analysts;

    - announcements of technological innovations;

    - announcements relating to strategic relationships, acquisitions or
      industry consolidation;

    - customer relationship developments; and

    - conditions affecting the Internet or healthcare industries.

VOLATILITY OF OUR COMMON STOCK PRICE MAY EXPOSE US TO SECURITIES LITIGATION.

    In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted. Due to the extreme price and volume fluctuations historically
experienced by Internet related stocks, particularly over the last 12 months, we
may be particularly susceptible to this kind of litigation. If this were to
happen to us, litigation would be

                                       23
<PAGE>
expensive and would divert management's attention from then-existing business
operations. In addition, any litigation that resulted in liability against us
could adversely affect our business, financial condition and the market price of
our common stock.

OUR MANAGEMENT HAS BROAD DISCRETION IN SPENDING THE PROCEEDS OF THIS OFFERING
AND MAY DO SO IN WAYS WITH WHICH OUR STOCKHOLDERS DISAGREE.

    Other than the repayment of approximately $2.0 million of outstanding
indebtedness under a subordinated term loan and the payment of $10.3 million to
Snap due in the first year of our strategic alliance agreement, we have no
specific plans for the net proceeds of this offering. We intend to use the
remainder of the net proceeds for general corporate purposes, including working
capital, expansion of our sales and marketing efforts, content development and
licensing, and advertising and brand promotion. We may also use a portion of the
proceeds for the acquisition of or investment in companies, technologies or
assets that complement our business. However, we have not determined the amounts
we plan to expend in any of these areas or the timing of these expenditures.
Consequently, our board of directors and management will have significant
flexibility in using the net proceeds of this offering. Because of the number
and variability of factors that determine our use of the net proceeds of this
offering, we cannot assure you that such uses will not vary from our current
intentions or that stockholders will agree with the uses we have chosen. See
"Use of Proceeds."

INVESTORS WILL INCUR IMMEDIATE DILUTION.


    The initial offering price of our common stock will be substantially higher
than the pro forma net tangible book value per share of the outstanding common
stock immediately after the offering. If you purchase common stock in this
offering, you will incur immediate and substantial dilution in the pro forma net
tangible book value per share of the common stock from the price you pay for
common stock. Assuming an initial public offering price of $10.00 per share, you
will experience a net tangible book value dilution per share of $8.17. We also
have a large number of outstanding stock options and warrants to purchase the
common stock with exercise prices significantly below the estimated initial
public offering price of the common stock. To the extent that these options and
warrants are exercised, there will be further dilution. See "Dilution."


OUR OFFICERS, DIRECTORS AND THEIR AFFILIATED ENTITIES WILL HAVE SIGNIFICANT
CONTROL OF HEALTHGATE AFTER THIS OFFERING.

    After this offering, our officers and directors will own approximately 22%
of our outstanding common stock. In addition, entities with which our outside
directors are affiliated will own approximately 23.4% of our outstanding common
stock. If our officers, directors and their affiliated entities act together,
they will be able to significantly influence the management and affairs of
HealthGate and will have the ability to control most matters requiring
stockholder approval, including the election of directors and approval of
significant corporate transactions. This concentration of ownership may have the
effect of delaying, deferring or preventing an acquisition of HealthGate and may
adversely affect the market price of our common stock. See "Principal
Stockholders."

OUR CERTIFICATE OF INCORPORATION AND BYLAWS INCLUDE ANTI-TAKEOVER PROVISIONS
WHICH MAY DETER OR PREVENT A TAKEOVER ATTEMPT.

    Some provisions of our certificate of incorporation and bylaws and
provisions of Delaware law may deter or prevent a takeover attempt, including an
attempt that might result in a premium over the

                                       24
<PAGE>
market price for our common stock. See "Description of Capital
Stock--Anti-takeover Effects of Provisions of the Restated Charter and Restated
Bylaws." These provisions include:

    STAGGERED BOARD OF DIRECTORS.  Our board of directors is divided into three
classes serving terms currently expiring in 2000, 2001 and 2002 and directors
may only be removed for cause. These provisions may limit the ability of holders
of common stock to remove our board of directors through a proxy contest.

    STOCKHOLDER PROPOSALS.  Our stockholders must give advance notice, generally
60 days prior to the relevant meeting, for stockholder nominations of candidates
for our board of directors and for certain other business to be conducted at any
stockholders' meeting. This limitation on stockholder proposals could inhibit a
change of control by delaying action on any proposed change in control until the
annual meeting of stockholders.

    PREFERRED STOCK.  Our certificate of incorporation authorizes our board of
directors to issue up to 10 million shares of preferred stock having such rights
as may be designated by our board of directors, without shareholder approval.
This issuance of preferred stock could inhibit a change in control by making it
more difficult to acquire the majority of our voting stock.

    DELAWARE ANTITAKEOVER STATUTE.  The Delaware corporation law restricts
certain business combinations with interested stockholders upon their acquiring
15% or more of our common stock. This statute may have the effect of inhibiting
a non-negotiated merger or other business combination.

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

    The market price for our common stock could fall substantially if our
stockholders sell large amounts of our common stock in the public market
following this offering. These sales, or the possibility that these sales may
occur, could also make it more difficult for us to sell equity or equity related
securities if we need to do so in the future to address then-existing financing
needs. The number of shares of common stock available for sale in the public
market is limited by restrictions under federal securities law requiring the
registration or exemption from registration in connection with the sale of
securities. In addition, sales of our common stock are restricted by lock-up
agreements that we, our directors and officers and most of our existing
stockholders have entered into with the underwriters. The lock-up agreements
restrict us, our directors and officers and substantially all of our existing
stockholders, from selling or otherwise disposing of any shares for a period of
180 days after the date of this prospectus without the prior written consent of
SG Cowen Securities Corporation. SG Cowen Securities Corporation may, however,
in its sole discretion and without notice, release all or any portion of the
shares from the restrictions in the lock-up agreements.

    After this offering, we will have 16,445,472 outstanding shares of common
stock. These shares will become eligible for sale in the public market as
follows:

   2,435,395                  At various times thereafter, subject to applicable
                              holding period requirements
</TABLE>


    We intend to file one or more registration statements to register shares of
common stock subject to outstanding stock options and common stock reserved for
issuance under our stock option plan after the expiration of the 180-day lockup.
We expect the additional registration statement to become effective immediately
upon filing. In addition, upon completion of this offering and the conversion of
our outstanding preferred stock into common stock, which will happen upon the
completion of this


                                       25
<PAGE>

offering, the holders of approximately 8,030,556 shares of our common stock will
have the right to require us to register their shares for sale to the public.
Substantially all of these shares are subject to the 180-day lock-up, described
above. If these holders cause a large number of shares to be registered and sold
in the public market, our stock price could fall. See "Shares Eligible for
Future Sale."


WE HAVE NO INTENTION TO PAY DIVIDENDS ON OUR COMMON STOCK.

    We have never declared or paid any cash dividends on our common stock. We
currently intend to retain all future earnings to finance the expansion of our
business.

<PAGE>
                                USE OF PROCEEDS

    We estimate that the net proceeds to us from the sale of the 3,750,000
shares of common stock in this offering will be approximately $32.5 million
($37.7 million if the underwriters' over-allotment is exercised in full),
assuming an initial public offering price of $10.00 per share and after
deducting estimated underwriting discounts and commissions and offering expenses
payable by us. The principal reasons for this offering are to provide working
capital, to create a public market for our common stock and to facilitate our
future access to public capital markets.


    We expect to use $10,250,000 of the net proceeds of this offering to pay the
first year fees due to Snap under our strategic alliance agreement with Snap. We
have also agreed to pay Snap up to an additional $5.0 million in the first year
if Snap delivers more than a minimum number of click-throughs to the co-branded
Snap/HealthGate Web site and would expect to use a portion of the net proceeds
to pay this additional fee.


    We expect to use $2,000,000 of the net proceeds of this offering to repay
all of the indebtedness outstanding under a subordinated note. This note bears
interest at the fixed rate of 13% per year and is scheduled to mature on
March 26, 2003.

    We expect to use the remainder of the net proceeds of this offering for
general corporate purposes, including working capital, but we have no current
plan for the amounts we may spend on any specific aspect of our business or the
timing of these expenditures. We may also use a portion of the proceeds for the
acquisition of or investment in companies, technologies or assets that
complement our business. However, we have no present understandings, commitments
or agreements with respect to any potential acquisitions or investments. As a
result, our management will have broad discretion to allocate the net proceeds
from this offering. Pending these uses, we intend to invest the net proceeds of
this offering in short term, investment grade, interest bearing instruments.

                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our common stock. We
currently intend to retain all future earnings to finance the expansion of our
business and, therefore, do not anticipate declaring or paying any cash
dividends on our common stock in the foreseeable future.

                                    DILUTION


    The pro forma net tangible book value of HealthGate as of September 30, 1999
was $(2,014,000), or $(.16) per share of common stock. Pro forma net tangible
book value per share represents the amount of total tangible assets less total
liabilities, divided by the number of shares of common stock outstanding after
giving effect to the issuance of 500,000 shares of common stock to Snap in
November 1999 and to the conversion of all outstanding preferred stock into
7,530,556 shares of common stock upon the closing of the offering.



    After giving effect to the sale of 3,750,000 shares of common stock we are
offering at an assumed initial public offering price of $10.00 per share and
after deducting estimated underwriting discounts and commissions and offering
expenses, HealthGate's pro forma net tangible book value as of September 30,
1999 would have been approximately $30.0 million, or $1.83 per share. This
represents an immediate increase in pro forma net tangible book value of $1.99
per share to existing stockholders and an immediate dilution of $8.17 per share
to new investors purchasing shares of common stock in the offering. The
following table illustrates this dilution:

    This discussion and table assumes no exercise of options outstanding under
HealthGate's stock option plans. As of November 19, 1999, there were options
outstanding to purchase a total of 2,610,684 shares of common stock at a
weighted average exercise price of $4.31 per share. As of November 19, 1999,
there were outstanding warrants to purchase 477,546 shares of our common stock
with a weighted average exercise price of $.13 per share, a warrant to purchase
1,189,800 shares of our common stock with an exercise price of $9.49 per share
(subject to adjustment), and a warrant to purchase 1,941,035 shares of our
common stock with an exercise price per share equal to the initial public
offering price (subject to adjustment). To the extent that any of these options
or warrants are exercised, there will be further dilution to new investors.

1999, are derived from unaudited financial statements included elsewhere in this
prospectus. In the opinion of management, the unaudited financial statements
have been prepared on a basis consistent with the audited financial statements
which appear elsewhere in this prospectus. The historical results are not
necessarily indicative of the operating results to be expected in the future.


    Unaudited pro forma basic and diluted net loss per share have been
calculated assuming the conversion of all outstanding preferred stock into
common stock, as if the shares had converted immediately upon their issuance.

FINANCIAL STATEMENTS AND RELATED NOTES WHICH APPEAR ELSEWHERE IN THIS
PROSPECTUS. THE FOLLOWING DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT
INVOLVE RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM

PARTICULARLY UNDER THE HEADING "RISK FACTORS."

OVERVIEW

    HealthGate is an Internet provider of reliable, objective, comprehensive and
up-to-date healthcare information helping physicians and other healthcare
professionals, patients and health-conscious consumers make better informed
healthcare decisions. We have aggregated and developed what we believe are the
most extensive health and medical libraries of any online provider, currently
totaling approximately 27 million different pages of health and medical
information from approximately 300 sources. This content includes
internationally recognized journals, authoritative government sources and
extensive bibliographic databases representing 27 independent content providers.
We adapt and integrate this diverse content through our internally developed
software programs, which include our proprietary ReADER-Registered Trademark-
natural language searching software, in order to facilitate search and retrieval
of relevant information. In addition, we use our technology to provide text
conversion and Web site hosting services for traditional print publishers,
thereby increasing the online healthcare resources accessible through our
content libraries.


    We distribute our content through a network of proprietary and affiliated
Web sites that comprise the HealthGate Network. The HealthGate Network includes
(1) our own Web sites, www.healthgate.com and www.bewell.com in the United
States and www.healthgate.co.uk in the United Kingdom; (2) customized,
co-branded CHOICE Web sites for institutions, principally hospitals and
businesses, which carry both HealthGate's and the entity's name, are designed as
a seamless component of the entity's own Web site and, for certain institutions
and businesses, complement the healthcare information, products and services
they already offer or sell through their own Web sites; and (3) other co-branded
third party Web sites to which we syndicate our proprietary and licensed
content, including the Health Channel of www.snap.com for which we will be
designated as an anchor tenant provider of health content following the
completion of this offering.



REVENUE


    We derive revenue primarily from (1) services and (2) online advertising,
sponsorship and e-commerce.


SERVICES REVENUE


    To date, services revenue has been derived principally from development,
implementation and hosting fees associated with our activePress service and, to
a lesser extent, from syndicating our content to third party Web sites. Revenue
from activePress services and content syndication is recognized ratably over the
terms of the agreements which generally range from one to two years.

    We commercially introduced our CHOICE Web site product in early 1999 and as
of September 30, 1999 had delivered 39 CHOICE Web sites to enterprise clients.

    Under our CHOICE Web site arrangements, we are generally paid an upfront fee
for developing, implementing and hosting a CHOICE Web site for our customer. In
addition, the arrangements typically provide the opportunity for us to place
third party advertising and sponsorship on the customer's CHOICE Web site. We
collect the fees for this advertising and sponsorship from the third

                                       33
<PAGE>
party and pay a commission to the customer. However, as part of our agreements
with 14 of our initial CHOICE customers, we guaranteed that we will pay minimum
advertising and sponsorship commissions to these customers in amounts
approximately equal to the fees paid to us by the customer for the initial term
of their CHOICE agreements and, in a few cases, in amounts that exceed those
fees. Once these customers have paid the upfront fee to us or, if applicable,
our authorized reseller, we are obligated to pay these guaranteed commissions to
the customer, generally on a quarterly basis, regardless of whether or not we
have actually sold any advertising or sponsorship on the CHOICE Web site. We
have entered into these types of arrangements for promotional purposes to
establish our CHOICE Web site product but beginning in July 1999 have
discontinued the use of these arrangements as a standard practice.

    Revenue from fees received for CHOICE Web site development, implementation
and hosting is recognized ratably over the term of the underlying agreement
between us, our CHOICE customer and, if applicable, our authorized reseller,
which generally ranges from one to three years. For those arrangements in which
we have guaranteed advertising and sponsorship commissions, we do not recognize
revenue unless the guaranteed commissions are less than the fees paid to us.
Rather, we recognize payments made to us as a customer deposit. Any excess of
fees paid to us over guaranteed commissions is recognized as revenue ratably
over the term of the agreement. If the advertising and sponsorship commissions
that we guarantee to the customer exceed the fees paid to us, we recognize the
excess as expense upon signing the agreement. For arrangements in which we sell
through a reseller, we do not recognize any revenue until an agreement between
us, our CHOICE customer and our authorized reseller has been finalized and the
CHOICE Web site has been delivered. As we sell advertising or sponsorship on
these CHOICE Web sites to third parties, we will recognize advertising revenue
from these CHOICE Web sites. As of September 30, 1999, we have sold advertising
or sponsorship on only five CHOICE Web sites. Payments made to customers under
advertising and sponsorship commission guarantees are recorded as reductions of
the related customer deposit.


    Of the 39 CHOICE Web sites that we had delivered as of September 30, 1999,
we have arrangements with 14 of these CHOICE customers under which we guarantee
to them advertising and sponsorship commissions.



ONLINE ADVERTISING, SPONSORSHIP AND E-COMMERCE REVENUE


    Advertising and sponsorship revenue includes revenue from banner advertising
and sponsorship of discrete portions of our content libraries. Advertising
revenue is derived principally from short-term advertising contracts in which we
typically guarantee a minimum number of impressions to be delivered to users
over a specified period of time for a fixed fee. Advertising revenue is
recognized in the period in which the advertisement is displayed at the lesser
of the ratio of impressions delivered over total guaranteed impressions or on a
straight line basis over the term of the contract, provided that we do not have
any significant obligations remaining. To the extent that minimum guaranteed
impressions are not met, we defer recognition of the corresponding revenue until
the guaranteed impressions are delivered. We use NetGravity's AdServer software
to track banner advertising impressions and issue a NetGravity Traffic Report
weekly to our advertisers. Our advertising statistics are audited to assure
accuracy by the Audit Bureau of Circulation Interactive, an independent audit
bureau in the advertising industry. Sponsorship revenue is derived principally
from contracts ranging from one to six months. Sponsorships are designed to
support broad marketing objectives, including brand promotion, awareness,
product introductions, online research and the integration of advertising with
editorial content. Sponsorship revenue is generally recognized ratably over the
terms of the applicable agreements.

    Advertising and sponsorship revenue also includes barter revenue, which
represents an exchange by us of advertising space on our own Web sites for
reciprocal advertising space on other Web sites.

                                       34
<PAGE>
Revenue from barter transactions is recognized during the period in which we
display the advertisements. Barter transactions are recorded at the estimated
fair value of the advertisements provided, unless the fair value of the
advertising services received is more evident. Barter expenses are recognized
when our advertisements are run on the reciprocal Web sites, which is typically
in the same period during which the advertisements are run on our own Web sites.
Barter expenses are included in sales and marketing expenses. These barter
transactions have no impact on our cash flows and, typically, no significant
impact on our results of operations. We anticipate that barter revenue will
continue to decrease as a percentage of total revenue in the future as we
continue to focus on selling advertising for cash.

    E-commerce revenue has been derived principally from individual user online
subscriptions and from transaction fees for fee-based access to portions of our
own Web sites. Revenue from user subscriptions is recognized ratably over the
subscription period, and revenue from transaction-based fees is recognized when
the related service is provided. E-commerce revenue declined during 1998 and in
the first six months of 1999 as we elected to provide more content for free
through our own Web sites in order to attract additional users to our own Web
sites. However, we expect that transactional fees associated with our providing
full-text journal articles from our activePress clients, including additional
Blackwell Science journals and the NEW ENGLAND JOURNAL OF MEDICINE, which is
expected to be fully operational by the end of 1999, will result in an increase
in e-commerce revenue beginning at the end of 1999. Additionally, we are
exploring other e-commerce opportunities to offer products and services to our
users.


    Our business model is still in an emerging stage, and revenue and income
potential from our business is unproven. Our limited operating history makes an
evaluation of our business and our prospects difficult. Investors should not use
our past results as a basis to predict future performance. We have incurred net
losses since inception and had an accumulated deficit of approximately
$10.5 million as of December 31, 1998 and $29.3 million as of September 30,
1999. We intend to significantly increase our sales and marketing efforts and
expenditures. We also intend to continue to invest in content development and
licensing and advertising and brand promotion. As a result, we expect to incur
additional losses for the foreseeable future, and we can not assure investors
that we will ever achieve significant revenue or profitability or, if either
significant revenue or profitability is achieved, that we will be able to
sustain them. See "Risk Factors--We have a limited operating history and have
recently introduced new services which makes an evaluation of our business based
on past operating results difficult." Also, see "Risk Factors--We have a history
of losses, we expect that losses will continue for the foreseeable future and
our independent accountants have expressed substantial doubt about our ability
to continue as a going concern."



NON-CASH EXPENSES



    We recorded deferred compensation of $2,307,000 in the nine months ended
September 30, 1999, representing the difference between the exercise price of
stock options granted and the fair market value of the underlying common stock
at the date of grant. The difference is recorded as a reduction of stockholders'
equity and is being amortized over the vesting period of the applicable options,
typically three years. Of the total deferred compensation amount, $509,000 had
been amortized as of September 30, 1999. The amortization of deferred
compensation is recorded as an operating expense. We currently expect to
amortize the following remaining amounts of deferred compensation as of
September 30, 1999 in the periods indicated:

    In June 1999, we entered into a development and distribution agreement with
GE Medical Systems. Under the terms of this agreement, GE Medical Systems may
sell our standard CHOICE Web site product and GE Medical Systems branded
enhanced versions of our CHOICE Web site product through its worldwide sales
force into its worldwide customer base of hospitals and other patient care
facilities. We believe that this agreement will benefit us through the
association of the GE Medical Systems name with HealthGate in general, and our
CHOICE product in particular, and through the efforts of GE Medical Systems to
distribute both our standard CHOICE product and the GE Medical Systems enhanced
versions of our CHOICE product. Therefore, in connection with this agreement, in
June 1999, we issued a warrant to General Electric Company for the purchase of
up to 1,189,800 shares of our common stock. The warrant has a term of five years
and an exercise price of $9.49 per share (subject to potential adjustments for
certain equity offerings subsequent to the warrant's issuance and other events)
and is immediately exercisable. The fair value of this warrant was determined to
be $10.3 million using the Black-Scholes option pricing model. This amount has
been recorded as marketing and distribution rights, and will be amortized as
sales and marketing expense on a straight-line basis over the one year
contractual term of the related development and distribution agreement. During
the nine months ended September 30, 1999, we recorded amortization expense of
$2,941,000. In the event the exercise price of this warrant is adjusted, its
fair value will increase. See "Business--Strategic Affiliations and
Relationships--Marketing and Distribution."



    In November 1999, we entered into a three-year marketing and reseller
agreement with Columbia Information Systems under which Columbia Information
Systems agreed to endorse us as the preferred provider of patient and consumer
oriented health content for Web sites owned or operated by Columbia/HCA
hospitals and affiliates. We believe that this agreement will benefit us,
generally, through the association of the Columbia Information Systems and
Columbia/HCA names with HealthGate and through their performance of the specific
terms described in the Business section under the heading "Strategic
Affiliations and Relationships--Marketing and Distribution--Columbia Information
Systems, Inc." Therefore, in connection with this agreement, we issued a warrant
to CIS Holdings, Inc. for the purchase of up to 1,941,035 shares of our common
stock. The warrant has a term of three years, an exercise price per share equal
to the initial public offering price (subject to adjustment in certain
circumstances) and is exercisable on the earlier of the consummation of this
offering, certain private placements of securities, a sale of HealthGate or
March 31, 2000. We expect to record the fair value of this warrant as marketing
and distribution rights, and amortize the value as a sales and marketing expense
on a straight-line basis over the three-year contractual term of the related
agreement. Based on the currently anticipated offering price range, we expect
the value of this warrant to range from approximately $10.7 million to $13.1
million. If the initial public offering price is above the currently anticipated
offering price range, this value will be higher. See "Business--Strategic
Affiliations and Relationships--Marketing and Distribution."



    In October 1999, we entered into a three-year strategic alliance agreement
with Snap! LLC and Xoom.com, Inc. Under this agreement, following HealthGate's
payments of fees to Snap, as described below, Snap will provide various services
to us to promote our name, our www.healthgate.com Web site, our co-branded
CHOICE Web sites and the products and services we offer. In exchange for the
services provided to us by Snap during the first year of the agreement, we have
agreed to pay Snap a minimum fee of $10.0 million and 500,000 shares of our
common stock, plus a $250,000 production and content integration fee. We have
agreed to pay Snap minimum fees of $15.0 million in each of the second and third
years of the agreement for the services provided to us by Snap in those years.
We have also agreed to pay Snap up to an additional $5.0 million in the first
year, $10.0 million in the second year and $15.0 million in the third year of
the agreement if Snap delivers more than a minimum number of click-throughs to
the co-branded Snap/HealthGate Web site in the respective years. We expect to
amortize the fair value of 250,000 shares of our common stock as a sales and
marketing expense on a straight-line basis over the first year of the related

the agreement. The value of these shares was $4.5 million at the time of
issuance. However, the final value of these shares will be determined when Snap
and Xoom have combined with certain assets of NBC to form NBC Internet, which
combination is presently expected to occur prior to December 31, 1999. See
"Business--Strategic Affiliations and Relationships--Marketing and
Distribution."


RESTATEMENT OF 1999 FIRST QUARTER REVENUE

    During the three months ended March 31, 1999, we recognized services revenue
of $82,000 related to two CHOICE Web site agreements. During the second quarter
of 1999, it was learned that certain material terms related to advertising and
sponsorship commissions guaranteed to the customers of these sites had not been
finalized at March 31, 1999. Accordingly, we have restated our results of
operations for the three months ended March 31, 1999 to reverse the $82,000 of
services revenue related to these sites. These amounts were recorded as customer
deposits. In the opinion of management, all adjustments necessary to revise the
quarterly financial statements have been recorded. Below is a summary of our
results of operations for the three months ended March 31, 1999:

    We have implemented additional financial and management controls and
procedures which we believe will improve the controls surrounding the
recognition of revenues. See "Risk Factors--We have had to restate our financial
statements for the first quarter of 1999 and if we are not able to monitor and
follow our newly implemented internal controls, our business prospects and the
price of our common stock may suffer."


RESULTS OF OPERATIONS


    Through December 31, 1996, we were a development stage company, and the
majority of our activities were related to development of products and services,
exploration of different sales and marketing channels, the build-up of hardware
and software infrastructure to support our www.healthgate.com Web site and the
establishment of the business, operations and financing of our company. In 1997,
1998 and the nine months ended September 30, 1999, we experienced growth in our
business and introduced new services. Therefore, while comparisons are drawn
below, in many instances meaningful conclusions cannot be drawn from them.

COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 1999 WITH THE NINE MONTHS
ENDED SEPTEMBER 30, 1998


REVENUE


    Total revenue was $1,736,000 for the nine months ended September 30, 1999
compared to $1,845,000 for the nine months ended September 30, 1998, a decrease
of $109,000 or 6%. Services revenue for the nine months ended September 30, 1999
increased to $1,214,000 from $1,110,000 for the nine months ended September 30,
1998, due primarily to an increase in the revenue derived from content
syndication fees. Advertising and sponsorship revenue decreased by $171,000 to
$350,000 in the nine months ended September 30, 1999 from $521,000 in the nine
months ended September 30, 1998, due primarily to a $277,000 decrease in barter
advertising arrangements for the nine months ended September 30, 1999 to $73,000
from $350,000 for the nine months ended September 30, 1998. This decrease is due
to our continued reduction in emphasis on barter arrangements and increased
focus on selling advertising for cash. Advertising paid for with cash increased
by $106,000 to $277,000 in the nine months ended September 30, 1999 from
$171,000 in the nine months ended September 30, 1998. E-commerce revenue
decreased to $172,000 in the nine months ended September 30, 1999 from $214,000
in the nine months ended September 30, 1998. This net decrease in e-commerce
revenue was due primarily to a decrease in subscription revenue resulting from a
decrease in the number of monthly subscriptions purchased by individuals. This
decrease in monthly subscriptions resulted in large part from our continued
implementation of our plan to provide more content for free through our own Web
sites in order to attract additional users to our own Web sites and generate
additional advertising revenue. In the nine months ended September 30, 1999, two
customers represented 45% of total revenue, Blackwell Science (33%) and WebMD
(12%). In the nine months ended September 30, 1998, two customers represented
62% of total revenue, Blackwell Science (44%) and WebMD (18%).



    Of the 39 CHOICE Websites that we have delivered as of September 30, 1999,
we have arrangements with 14 of these CHOICE customers under which we have
guaranteed advertising and sponsorship commissions in an amount approximately
equal to the fees paid by the customer, regardless of whether we sell any
advertising or sponsorship on the customer's CHOICE Web site. For any agreements
with guarantees, we have not recognized fees paid by the customer as revenue but
as a customer deposit, up to the amount of the applicable guarantee. We entered
into this type of arrangement for promotional purposes, but have discontinued
the use of this arrangement as a standard practice. For these CHOICE customers,
we recognize as revenue the excess of the fee paid over the guarantee owed
ratably over the terms of these customers' agreements.


COSTS AND EXPENSES


    COST OF REVENUE.  Cost of revenue consists primarily of salaries and related
costs for personnel directly involved with providing our Web services, royalties
associated with licensed content, and related equipment and software costs. Cost
of revenue increased 76% to $1,445,000 in the nine months ended September 30,
1999 from $822,000 in the nine months ended September 30, 1998, due primarily to
higher royalty expense for more licensed content and higher depreciation costs
related to additional equipment purchases.



    RESEARCH AND DEVELOPMENT.  Research and development expenses consist
primarily of salaries and related costs associated with the development and
support of our Web-based service offerings. Research and development expenses
increased 240% to $3,053,000 in the nine months ended September 30, 1999 from
$897,000 in the nine months ended September 30, 1998, due primarily to
additional salaries and related costs from the hiring of technical and
development personnel.



    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
salaries, commissions and related costs for sales and marketing personnel, as
well as the cost of advertising, marketing and promotional activities. Sales and
marketing expenses increased to $5,718,000 in the nine months ended
September 30, 1999 from $1,033,000 in the nine months ended September 30, 1998.
During the nine


                                       38
<PAGE>

months ended September 30, 1999, a non-cash expense of $2,941,000 was recorded
for the amortization of a warrant to purchase 1,189,800 shares of our common
stock issued to General Electric Company in connection with a development and
distribution arrangement. The fair value of this warrant was determined using
the Black-Scholes option pricing model and is being amortized on a straight-line
basis over 12 months of the contractual arrangement. The remaining increase of
$1,744,000 in sales and marketing expenses was primarily due to additional
salaries and related costs associated with the newly hired sales and marketing
personnel, and increased advertising and brand promotion activities.



    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of salaries and related costs for executive and administrative
personnel, as well as legal, accounting and insurance costs. General and
administrative expenses increased 148% to $1,667,000 in the nine months ended
September 30, 1999 from $672,000 in the nine months ended September 30, 1998.
This increase was due primarily to salaries and related costs for newly hired
administrative personnel, higher salaries and related costs for existing
personnel and increased professional services fees. In addition, we amortized
$509,000 of the total deferred compensation relating to stock options as an
expense in the nine months ended September 30, 1999. The remaining total
deferred compensation is being amortized over the vesting period of the
individual options.


INTEREST EXPENSE, NET


    Interest expense, net of interest income, increased to $323,000 in the nine
months ended September 30, 1999 from $182,000 in the nine months ended
September 30, 1998. The increase was due primarily to interest incurred on a
$2,000,000 subordinated note and an increase in interest expense associated with
capital leases. Interest expense for the nine months ended September 30, 1999
also included debt discount and issuance cost amortization totaling $64,000
related to the subordinated note.


INCOME TAXES


    We have incurred significant losses for all periods from inception through
September 30, 1999. A valuation allowance has been recorded for the entire
deferred tax asset as a result of uncertainties regarding the utilization of the
asset due to HealthGate's lack of earnings history.


COMPARISON OF YEAR ENDED DECEMBER 31, 1998 WITH YEAR ENDED DECEMBER 31, 1997

REVENUE


    Total revenue was $2,434,000 in 1998 compared to $1,285,000 in 1997, an
increase of $1,149,000 or 89%. Services revenue in 1998 was $1,486,000, which
was comprised primarily of revenue from our activePress arrangement with
Blackwell Science, one of our stockholders, and revenue from content syndication
arrangements. Services revenue in 1997 was not significant. Advertising and
sponsorship revenue decreased to $665,000 in 1998 from $863,000 in 1997, due
primarily to a decrease in revenue under barter advertising arrangements to
$436,000 in 1998 from $607,000 in 1997. In addition, advertising and sponsorship
revenue derived from cash sales decreased to $229,000 in 1998 from $256,000 in
1997, due to our editorial decision to eliminate sponsor-provided content areas.
During 1998, we began to place less emphasis on barter arrangements and focus
more on selling advertising for cash. We anticipate that barter revenue will
continue to decrease as a percentage of total revenue in the future. E-commerce
revenue decreased to $283,000 in 1998 from $333,000 in 1997. This decrease in
e-commerce revenue was due primarily to a decrease of $24,000 in transaction
based fees resulting from a decrease in the number of full text journal
transactions and due to a decrease of $26,000 in subscription revenue
attributable to a decrease in the number of subscriptions. During this time, we
elected to provide more content for free through our own Web sites in order to
generate additional advertising revenue by attracting additional users to our
own Web sites. In 1998, two customers


                                       39
<PAGE>

represented 62% of total revenue, Blackwell Science (44%) and WebMD (18%). In
1997, two customers represented 37% of total revenue, Lycos (19%) and Blackwell
Science (18%).


COSTS AND EXPENSES

    COST OF REVENUE.  Cost of revenue consists primarily of salaries and related
costs for personnel directly involved with providing our Web services, royalties
associated with licensed content, and related equipment and software costs. Cost
of revenue increased 29% to $1,181,000 in 1998 from $912,000 in 1997. The
increase was primarily attributable to higher royalty expenses for licensed
content.

    RESEARCH AND DEVELOPMENT.  Research and development expenses consist
primarily of salaries and related costs associated with the development and
support of our Web-based service offerings. Research and development expenses
increased 63% to $1,450,000 in 1998 from $891,000 in 1997, due primarily to
salaries associated with newly hired development personnel and related
recruiting costs. We anticipate that research and development expenses will
continue to increase as HealthGate develops and enhances its Web-based service
offerings, and hires additional technical and development personnel.

    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
employee salaries, commissions and related costs, as well as the cost of
advertising, marketing and promotional activities. Sales and marketing expenses
decreased 5% to $1,414,000 in 1998 from $1,496,000 in 1997, due primarily to a
corresponding decrease in expenses under barter advertising arrangements to
$418,000 in 1998 from $617,000 in 1997. The decrease in barter advertising
expenses was the result of our entering fewer barter advertising arrangements in
1998. The decrease in barter advertising expenses was partially offset by
increased salaries and related costs associated with newly hired sales and
marketing staff. We expect that sales and marketing expenses will increase as we
continue to expand our sales, marketing and advertising activities and hire
additional personnel for our sales and marketing force.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of salaries and related costs for executive and administrative
personnel, as well as legal, accounting and insurance costs. General and
administrative expenses increased 78% to $929,000 in 1998 from $521,000 in 1997.
The increase was due primarily to salaries and related costs associated with
newly hired administrative personnel, higher salaries and related costs
attributable to existing personnel and increased fees for professional services.
We expect that general and administrative expenses will continue to grow as we
increase our staffing to support expanded operations and facilities, and incur
expenses related to being a public company.

INTEREST EXPENSE, NET

    Interest expense, net of interest income, increased to $327,000 in 1998 from
$6,000 in 1997. The increase was due primarily to interest incurred on a
$2,000,000 convertible note payable to Blackwell Science and a $2,000,000
subordinated note, both issued in 1998, and to an increase in interest expense
associated with capital leases. Interest expense in 1998 includes debt discount
and debt issuance cost amortization totaling $54,000 related to the subordinated
note.

INCOME TAXES

    As of December 31, 1998, HealthGate generated a net operating loss
carryforward of $8,492,000. HealthGate's net operating loss carryforwards expire
beginning in 2010. Certain future changes in the share ownership of HealthGate,
as defined in the Tax Reform Act of 1996, may restrict the utilization of
carryforwards. A valuation allowance has been recorded for the entire deferred
tax asset as a result of uncertainties regarding the utilization of the asset
due to HealthGate's lack of earnings history.

COMPARISON OF YEAR ENDED DECEMBER 31, 1997 WITH YEAR ENDED DECEMBER 31, 1996

REVENUE

    Total revenue was $1,285,000 in 1997 compared to $408,000 in 1996, an
increase of $877,000 or 215%. The increase in total revenue was due primarily to
growth in advertising and sponsorship revenue, and to a lesser extent, an
increase in e-commerce revenue resulting from a higher volume of fee-based
transactions on our Web sites. Included in total revenue is revenue from barter
advertising transactions, which increased to $607,000 in 1997 from $125,000 in
1996. In 1997, two customers represented 37% of total revenue, Lycos (19%) and
Blackwell Science (18%). In 1996, two customers represented 26% of total
revenue, Infoseek (15%) and Lycos (11%); additionally, a single research and
development arrangement represented 21% of total revenue.

COSTS AND EXPENSES

    COST OF REVENUE.  Cost of revenue increased 85% to $912,000 in 1997 from
$492,000 in 1996. The increase in cost of revenue resulted primarily from
expanding our infrastructure to support increased activity on our Web sites, and
included higher salary and related costs, increased royalty costs associated
with licensed content and increased costs related to equipment and software.

    RESEARCH AND DEVELOPMENT.  Research and development expenses decreased 9% to
$891,000 in 1997 from $980,000 in 1996. The decrease was due primarily to a
reduction in costs associated with outside engineers and consultants, as we
realized cost savings by transitioning most development work to our own
employees. This decrease was partially offset by salaries associated with newly
hired development personnel and related costs.

    SALES AND MARKETING.  Sales and marketing expenses increased 39% to
$1,496,000 in 1997 from $1,080,000 in 1996. The increase was due primarily to
higher advertising costs, and to salaries and related costs associated with new
staff hired to support our expanded sales and marketing efforts. Barter
advertising expenses included in total sales and marketing expenses increased to
$617,000 in 1997 from $115,000 in 1996, as a result of increased barter
advertising arrangements in 1997.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses decreased
8% to $521,000 in 1997 from $568,000 in 1996. This decrease was due primarily to
reduced professional services costs, partially offset by increased salaries and
related costs associated with administrative personnel.

INTEREST EXPENSE, NET

    Interest expense, net of interest income, decreased to $6,000 in 1997 from
$14,000 in 1996, due primarily to increased interest income earned on higher
average cash balances invested.

LIQUIDITY AND CAPITAL RESOURCES


    Since inception, we have financed our operations primarily by the private
placement of debt and equity securities. In the period 1994 through 1997, we
received net proceeds of $4,434,000 from the issuance of several series of
redeemable convertible preferred stock. During 1998, we received net proceeds of
$3,929,000 through the issuance of a $2,000,000 convertible note payable to
Blackwell Science and a $2,000,000 subordinated note with detachable warrants.
The $2,000,000 subordinated note, which we plan to repay with a portion of the
proceeds of this offering, is secured by substantially all of our tangible and
intangible assets. We have generally financed computer and related hardware
needs through equipment lease financing arrangements. In August 1999, we entered
into an equipment leasing arrangement for up to $500,000 in financing for
computer equipment and furniture and fixtures and as of September 30, 1999, we
had entered into leases for $388,000 under this arrangement. As of
September 30, 1999, we had approximately $808,000 of cash and cash equivalents.


                                       41
<PAGE>

    In April 1999, we issued 546,028 shares of newly authorized Series E
redeemable convertible preferred stock for gross proceeds of $6,250,000. In
connection with the issuance of the Series E preferred stock, we paid $300,000
of fees and expenses to a placement agent, paid $111,000 of other issuance costs
and issued to the placement agent warrants to purchase 21,654 shares of our
common stock at an exercise price of $2.89 per share with an ascribed value of
$200,000. The placement fee, other issuance costs and warrant value was
reflected as a reduction of the proceeds from the Series E preferred stock
issuance. An additional 174,729 shares of Series E preferred stock were issued
upon conversion of the $2,000,000 convertible note payable to Blackwell Science.
The Series E preferred stock ranks senior in liquidation to the other classes of
preferred stock, and has certain veto rights. The Series E preferred stock
accrues cumulative annual dividends at 7% of its liquidation value (initially
$8,250,000). The dividends are compounded annually and, unless paid, are added
to the Series E preferred stock liquidation value. Concurrently with the closing
of this offering, we plan to pay in cash all accrued dividends on the Series E
preferred stock. At September 30, 1999, accrued dividends on the Series E
preferred stock totaled approximately $269,000. The Series E preferred stock is
convertible into a number of shares of common stock determined by dividing the
liquidation value by a conversion price per share of $2.89. The conversion price
is to be adjusted for certain dilutive events.



    At the time of issuance, each share of Series E preferred stock was
convertible into one share of common stock, which represents a discount from the
fair value of common stock on the date of the Series E issuance. The value
attributable to this conversion right represents an incremental yield, or a
beneficial conversion feature, which was recognized as a return to the preferred
stockholders. This amount, equal to the proceeds from the Series E offering, was
reported as accretion of preferred stock to redemption value of $7,639,000 in
the consolidated statement of operations in the period ended September 30, 1999
and represents a non-cash charge in the determination of net loss attributable
to common stockholders.



    For the nine months ended September 30, 1999, the cash used in operations
was $5,361,000. Cash used during this period was primarily due to the net loss
of $10,466,000, offset partially by depreciation and amortization of $3,408,000
(which includes a non-cash warrant expense of $2,941,000), non-cash compensation
expense of $509,000, an increase of $376,000 in accounts receivable and unbilled
accounts receivable, an increase of $21,000 in prepaid expenses and other
current assets, an increase of $1,462,000 in deferred offering costs related to
this offering, an increase of $128,000 in other assets, an increase of
$1,401,000 in accounts payable, an increase of $229,000 in accrued payroll, an
increase of $555,000 in customer deposits for CHOICE Web sites, an increase of
$403,000 in other accrued expenses (which consists primarily of $187,000 for
advertising and sponsorship commitments, $138,000 in professional fees, and
$78,000 in real property lease obligations) and an increase of $587,000 in
deferred revenue. For the nine months ended September 30, 1998, the cash used in
operations was $1,813,000. Cash used during this period was primarily due to the
net loss of $1,761,000, offset partially by depreciation and amortization of
$289,000, a net increase of $77,000 in accounts receivable and unbilled accounts
receivable, an increase of $56,000 in prepaid expenses and other current assets,
a decrease in other assets of $17,000, a decrease of $240,000 in accounts
payable, an increase of $170,000 in accrued payroll, and a decrease of $151,000
in deferred revenue. Increases in operating assets and liabilities were
primarily due to the growth of our business and operations during these periods.



    Cash used for investing activities consisted primarily of purchases of
property and equipment of $410,000 and $235,000, respectively, during the nine
months ended September 30, 1999 and 1998. We also entered into capital leases
for computer equipment totaling $523,000 and $503,000 during the nine months
ended September 30, 1999 and 1998, respectively.



    Cash provided by financing activities during the nine months ended
September 30, 1999 consisted primarily of net proceeds received from the
issuance of the Series E redeemable convertible preferred stock and common stock
of $5,848,000 partially offset by payments for capital lease obligations of
$230,000. During the nine months ended September 30, 1998, we received net
proceeds from the


                                       42
<PAGE>

issuance of a subordinated note payable and warrants of $3,929,000 which was
partially offset by payments for capital lease obligations of $177,000. At
September 30, 1999, we had outstanding commitments under capital leases of
$890,000 and under operating leases for equipment and office space of $568,000.
In addition, future minimum payments under content license agreements totaled
$1,609,000 at September 30, 1999. We expect our commitments under content
licensing to increase as we expand our content libraries.


    In October 1999, we entered into a three-year strategic alliance agreement
with Snap! LLC and Xoom.com, Inc. In exchange for the services provided to us by
Snap during the first year of the agreement, we have agreed to pay Snap a
minimum fee of $10.0 million and 500,000 shares of our common stock, plus a
$250,000 production and content integration fee. The $10.3 million cash
component of the first year minimum fee due to Snap is payable within thirty
days after the registration statement filed with the SEC in connection with this
offering is declared effective by the SEC. We have agreed to pay Snap minimum
fees of $15.0 million in each of the second and third years of the agreement for
the services provided to us by Snap in those years. We have also agreed to pay
Snap up to an additional $5.0 million in the first year, $10.0 million in the
second year and $15.0 million in the third year of the agreement if Snap
delivers more than certain minimum click-throughs to the co-branded
Snap/HealthGate Web site in the respective years. If Snap terminates the
agreement based on certain material breaches caused by us, we have agreed to
continue to pay Snap 55% of all fees payable by us under the agreement for the
remaining term of the agreement. If Snap and Xoom have not combined with certain
assets of NBC to form NBC Internet on or before March 31, 2000, we may terminate
the agreement and Snap must return to us all payments, including the common
stock we have issued to them as partial payment for the first year minimum fee,
made prior to the termination.

    We currently anticipate that our available cash resources combined with the
net proceeds from this offering will be sufficient to meet our anticipated
working capital and capital expenditure requirements for at least twelve months
after the date of this prospectus. However, we may need to raise additional
funds within the next twelve months to further expand sales and marketing,
develop new or enhanced products and services, respond to competitive pressures,
acquire or invest in complementary businesses or take advantage of unanticipated
opportunities. We can not guarantee that additional funding, if needed, will be
available on terms acceptable to us, or at all.


    We have received a report from our independent accountants containing an
explanatory paragraph stating that our historical losses and negative cash flows
from operations raise substantial doubt about our ability to continue as a going
concern because, as of the date they rendered their opinion, we did not have
access to sufficient committed capital to meet our projected operating needs
through at least September 30, 2000. The proceeds of this offering would
materially exceed the cash required for us to continue operations through at
least September 30, 2000. If this offering is not successful, we intend to
obtain alternative financing through the private placement of debt or equity and
reduce expenditures to minimize our requirements for additional financial
resources. We believe that, if this offering is not completed, we will be able
to successfully execute our alternative plans.


YEAR 2000 COMPLIANCE READINESS DISCLOSURE

IMPACT OF THE YEAR 2000

    Many currently installed computer systems and software products are unable
to distinguish between twentieth century dates and twenty-first century dates.
As a result, many companies' software and computer systems may need to be
upgraded or replaced to comply with these Year 2000 requirements. Our business
is dependent on the operation of numerous systems that could potentially be
impacted by Year 2000 related problems. Those systems include, among others:
hardware and software systems used by us to deliver services to our customers,
including our proprietary software systems as well as hardware and software
supplied by third parties; communications networks, such as

                                       43
<PAGE>
the Internet and private intranets, which we depend on to provide content to our
customers; internal systems of our customers and suppliers; hardware and
software we use internally to manage our business; and non-information
technology systems and services we use in our business such as the
telecommunications and building systems.

STATE OF READINESS

    COSTS.  To date, we have not incurred material costs in identifying or
evaluating Year 2000 compliance issues, although consideration of the Year 2000
question is an integral part of all our on-going developmental and operational
reviews. Most of our expenses to date have related to and are expected to
continue to relate to the operating costs associated with time spent by
employees in the evaluation process and Year 2000 compliance testing generally.
We presently anticipate that future expenditures will be less than $200,000. As
a young company, we purchased or developed new hardware and software at a time
when our suppliers and developers were sensitive to issues surrounding the
Year 2000 problem.


    RISKS.  We have completed internal assessments of our Year 2000 readiness,
with emphasis on our operating and administrative systems and the proprietary
software systems and third party software and hardware we use to deliver
services to our customers and users, and are not aware of any Year 2000 problems
that could reasonably be expected to have a material adverse effect on our
business. Our assessment plans have consisted of internal testing of our
systems, contacting third party vendors of hardware, software and services to us
and to our users, assessing and implementing repairs or replacements as required
and developing contingency plans in the event of Year 2000 problems arising as
the year ends. HealthGate has contacted its major vendors for software, hardware
and related services. These vendors have indicated that they are Year 2000
compliant. However, we can not guarantee that we have identified or will
identify all Year 2000 compliance problems in our infrastructure that may
require substantial revisions and fixes. Also, despite our testing and reviews,
we may experience Year 2000 problems related to the third party software,
hardware or other systems on which we are reliant, and any of these problems may
be time consuming or expensive to fix. We have given a warranty in our
activePress agreements with Blackwell Science and our CHOICE Web site agreement
with Columbia Information Systems that our applications and services are Year
2000 compliant. If our applications and services fail to be Year 2000 compliant,
these agreements could be terminated or we could be liable for damages, either
of which could have a material adverse effect on our business. In addition, the
purchasing patterns of customers or potential customers may be affected by Year
2000 questions, and any significant delays in making purchasing decisions could
either directly or indirectly affect us.


    In addition, we cannot be assured that the governmental agencies, utility
companies, Internet access companies, third party providers and others outside
our control will be Year 2000 compliant. The failure by these entities to be
Year 2000 compliant could result in a systemic failure beyond our control. We
believe that the most reasonably likely worst case scenario would result in a
prolonged Internet, telecommunications or electrical failure which would affect
our ability to meet our commitments to our customers or prevent our users from
accessing our Web sites or services, either of which, in turn, could have a
material adverse effect on our business, results of operations and financial
condition.

CONTINGENCY PLAN

    We have been engaged in an ongoing assessment of our readiness and have
developed contingency plans to address Year 2000 problems that may arise. The
results of our analyses and the responses received from third party vendors and
service providers were taken into account in developing these plans.

                                       44

RECENT ACCOUNTING PRONOUNCEMENTS

    We adopted Statement of Financial Accounting Standards (SFAS) No. 130,
"Reporting Comprehensive Income," effective January 1, 1998. This statement
requires a full set of general purpose financial statements to be expanded to
include the reporting of "comprehensive income." Comprehensive income is
comprised of two components, net income and other comprehensive income. During
the years ended December 31, 1996, 1997 and 1998, we had no items qualifying as
other comprehensive income; accordingly, the adoption of SFAS No. 130 had no
impact on our financial statements.


    In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information,"
which supersedes SFAS No. 14, "Financial Reporting for Segments of a Business
Enterprise." This statement changes the way public business enterprises report
segment information, including financial and descriptive information about their
selected segment information in interim and annual financial statements. Under
SFAS No. 131, operating segments are defined as revenue-producing components of
the enterprise which are generally used internally for evaluating segment
performance. SFAS No. 131 is effective for our fiscal year ended December 31,
1998 and had no effect on our financial position or results of operations. We
operate in one segment, which is providing healthcare and related information to
institutions and individuals through the Internet.



    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." The new standard establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. SFAS No. 133 is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000. HealthGate does
not expect SFAS No. 133 to have a material effect on its financial position or
results of operations.

                                    BUSINESS

OVERVIEW

    HealthGate is an Internet provider of reliable, objective, comprehensive and
up-to-date healthcare information helping physicians and other healthcare
professionals, patients and health-conscious consumers make better informed
healthcare decisions. We have aggregated and developed what we believe are the
most extensive health and medical libraries of any online provider, currently
totaling approximately 27 million different pages of health and medical
information from approximately 300 sources. This content includes
internationally recognized journals, authoritative government sources and
extensive bibliographic databases representing 27 independent content providers.
We adapt and integrate this diverse content through our internally developed
software programs, which include our proprietary ReADER-Registered Trademark-
natural language searching software, designed to facilitate the search and
retrieval of relevant information in response to each user's searching needs.

    Given the depth and breadth of our content, we provide healthcare
information to a wide range of online users, including physicians and other
healthcare professionals, patients and health-conscious consumers. We facilitate
user-friendly access to our content libraries by segmenting them into
collections for these three principal user groups. Content from any collection
is available to any type of user under a variety of pricing structures,
including free access, per transaction fee access and subscription. Our online
library targeted to physicians and other healthcare professionals includes
internationally recognized journals such as the NEW ENGLAND JOURNAL OF MEDICINE,
bibliographic databases such as MEDLINE, handbooks such as the Drug Information
Handbook, decision support materials such as the Poisoning and Toxicology
Compendium and Continuing Medical Education programs from the Boston University
School of Medicine and Professional Postgraduate Services. Our patient focused
online library includes patient education materials such as a series of over
3,000 patient education brochures published by the Clinical Reference Systems
division of Access Health. We have also created "Healthy Living" Webzines, a
proprietary series of consumer health magazines distributed exclusively through
the Web, and have produced Wellness Centers, which are compilations of selected
information from our online libraries for consumers, on 100 of the most
prevalent illnesses, diseases and medical conditions. In addition, we use our
technology to provide text conversion and Web site hosting services for
traditional print publishers, thereby increasing the number of online healthcare
resources accessible through our content libraries. While we aggregate and
develop content with the goal of meeting the specific needs of professionals,
patients and health-conscious consumers, we do not restrict access to the target
audience, for instance, giving patients and consumers access to more in-depth
information like leading medical journals written for medical professionals.


    We distribute our content through a network of proprietary and affiliated
Web sites that comprise the HealthGate Network. The HealthGate Network includes
(1) our own Web sites, www.healthgate.com and www.bewell.com in the United
States and www.healthgate.co.uk in the United Kingdom; (2) customized,
co-branded CHOICE-Registered Trademark- Web sites for institutions, principally
hospitals, and businesses, which carry both HealthGate's and an enterprise
client's name, are designed as a seamless component of an enterprise client's
Web site and, for certain institutions and businesses, complement the healthcare
information, products and services they already offer or sell through their own
Web sites; and (3) other third party co-branded Web sites to which we syndicate
our proprietary and licensed content, including the Health Channel of
www.snap.com for which we will be designated as an anchor tenant provider of
health content following the completion of this offering.


    We currently generate revenue from the following activities:

    - syndicating content to third party Web sites;

    - providing our activePress-TM- Web publishing services to traditional print
      publishers;

                                       46
<PAGE>
    - offering banner advertising and sponsorship of discrete portions of our
      content libraries to pharmaceutical companies, other healthcare
      advertisers and other businesses and organizations;

    - participating in e-commerce opportunities, including selling articles from
      full-text journals, monthly online subscriptions and medical text books;
      and

    - developing co-branded CHOICE Web sites for enterprise clients and
      distributing content through these CHOICE Web sites.

INDUSTRY BACKGROUND

    During the past decade, the Internet has emerged as a significant global
communications medium and an effective alternative to many forms of traditional
media. The Internet enables consumers to instantly retrieve information,
communicate with others and engage in e-commerce. As a result, Internet use is
growing rapidly. According to Jupiter Communications, an industry research firm,
the number of Internet users in the United States is expected to grow from
approximately 63 million in 1998 to approximately 116 million by 2002.

    The rapid growth of the Internet as a tool for communication, entertainment
and e-commerce has resulted in a proliferation of Web sites dealing with myriad
topics, products and services. Web sites such as America Online and Yahoo!
developed in response to Internet users' need for a simple means of navigating
the Internet. As the number of Internet users has increased, discrete user
groups have developed that share the same interests, such as people searching
for health and medical information, world and national news headlines and
personal investment information. These groups have, in turn, created a demand
for more focused subject specific Web sites. These subject specific Web sites
are a growing segment of the Internet. Among the most popular topics of these
types of Web sites is healthcare. A July 1999 research report published by Cyber
Dialogue, Inc., an industry research firm, estimates that approximately
25 million adults in the United States search online for health and medical
information, a number which Cyber Dialogue projects will grow to approximately
30 million in 2000.

    This demand for online healthcare content is creating many opportunities for
businesses to reach new consumers and expand their relationships with existing
customers. According to Cyber Dialogue, people that use the Internet to retrieve
online medical information are an attractive audience to businesses because
these individuals are typically older and more affluent than the general online
population. The Internet, unlike traditional media sources, allows businesses to
effectively target these consumers in an interactive manner. Through banner ads
and sponsorships, businesses are able to dynamically market their goods and
services in an efficient manner. According to Jupiter Communications, online
health and medical advertising in the U.S. is expected to grow from
$12.3 million in 1998 to $265.1 million in 2002. In addition to providing a new
marketing medium, the Internet has become a new distribution channel for
businesses, through which they can sell products to consumers.

    We believe that the company that establishes a clear brand identity as a
reliable source of comprehensive online healthcare information and services will
have a significant opportunity to capture a leading share of the online health
audience as this industry continues to grow.

BUSINESS STRATEGY

    Our objective is to capture a leading share of the online health audience as
this industry continues to grow. We plan to achieve this objective by delivering
a broad array of healthcare content and related

                                       47
<PAGE>
services to healthcare professionals, patients and consumers through the
HealthGate Network. Our strategy includes the following key elements:

    PROVIDE LEADING HEALTHCARE CONTENT AND TECHNOLOGY.  We seek to continually
expand our health and medical content libraries to enable healthcare
professionals, patients and consumers to easily satisfy their health-related
information needs without leaving the HealthGate Network. We are currently
focusing on expanding our content in the areas of prescription and over the
counter drugs, mental health, toxicology, decision support, alternative health
and geriatrics. In addition to continually expanding our content, we intend to
continue integrating content with technology in order to enhance the online user
experience. We are currently pursuing technology initiatives designed to provide
enhanced alert services, more sophisticated database searching capabilities and
personalization and content customization for the individual users. Given the
diversity of health-related Web sites, and the varying degrees of quality and
amount of information available on these Web sites, we believe professionals,
patients and consumers have a desire to be able to access reliable, objective,
comprehensive and up-to-date information on specific topics in a user-friendly
manner. We plan to continue to lead the way in making this information
accessible to both healthcare professionals and lay people.

    EXPAND THE HEALTHGATE NETWORK.  The HealthGate Network consists of (1) our
own Web sites, www.healthgate.com, www.bewell.com and www.healthgate.co.uk;
(2) clients' co-branded CHOICE Web sites; and (3) other co-branded Web sites,
which will include a co-branded Snap/HealthGate Web site, and other third party
Web sites, including the Health Channel of www.snap.com for which we have been
designated as an anchor tenant provider of health content, and Inteli-Health and
WebMD, which carry our syndicated content under license agreements. We plan to
increase the number of CHOICE Web sites on the HealthGate Network through
expanded marketing efforts, using both our in-house sales force and value added
resellers, such as Data General Corporation and GE Medical Systems, which resell
our products and services together with their complementary products and
services. We intend to further expand the HealthGate Network by continuing to
syndicate portions of our content libraries to other health-related Web sites.
By expanding the HealthGate Network, we believe we will be able to continue to
increase user traffic, thereby enabling us to generate increased revenue from
advertising, sponsorships and e-commerce opportunities.

    CONTINUE TO BUILD THE HEALTHGATE BRAND.  We believe that increased awareness
of the HealthGate brand will be important to our ability to continue to build
our user base and to attract additional customers, advertisers, sponsors and
strategic affiliates. We plan to allocate significant resources to continue to
build brand recognition by expanding the reach of the HealthGate Network. We
recently entered into a strategic alliance with Snap under which they will
provide various services to us to promote our name, our www.healthgate.com Web
site, our co-branded CHOICE Web Sites and the products and services we offer. We
believe that our relationship with Snap will increase awareness of the
HealthGate brand and help drive traffic to the HealthGate Network. Additionally,
by continuing to increase the number of co-branded CHOICE Web sites, we plan to
attract new users and build online communities, which are linked groups of users
with similar health related interests, by leveraging the name recognition of
local enterprises, including hospitals and other healthcare organizations,
corporations and academic institutions. We build brand awareness on our
www.healthgate.com, www.bewell.com and www.healthgate.co.uk Web sites by
offering users free access to a portion of our content libraries. Moreover, we
will continue to syndicate content under license agreements that require
licensees to display our name prominently on the syndicated content pages. These
agreements also require these licensees to enable users to reach our
www.healthgate.com Web site from the licensee's Web site by clicking on a
HealthGate link. In addition, we plan to build recognition of the HealthGate
brand through online and traditional media advertising, including advertising on
CHOICE Web sites, other promotional activities and marketing initiatives, and
through additional strategic affiliations, such as our affiliations with
Columbia Information Systems and Snap and Xoom.

                                       48
<PAGE>
    BROADEN THE RANGE OF PRODUCTS AND SERVICES.  We believe that broadening the
variety of products and services offered through the HealthGate Network will
allow us to better serve existing users, attract new users and keep our users on
the HealthGate Network for longer periods per visit. We intend to enhance our
offering of products and services to provide physician counseling services,
clinical trial recruitment and an integrated platform for linking clinical
information and patient education materials with electronic medical records. We
plan to leverage the HealthGate Network, including our enterprise-based CHOICE
accounts, to market these new, predominantly fee-based products and services. We
believe that these products and services will also make the HealthGate Network
even more attractive to potential advertisers and sponsors seeking a targeted
audience. Additionally, we are pursuing e-commerce partners to further leverage
revenue opportunities from the HealthGate Network user base.

    PURSUE ACQUISITIONS AND ADDITIONAL STRATEGIC AFFILIATIONS.  We intend to
pursue an acquisition and affiliation strategy focusing on proprietary content
and complementary technologies and services. Acquiring providers of proprietary
content will allow us to customize acquired content to better meet the needs of
our users and clients, as well as allow us to increase our user base. We also
plan to continue to pursue additional strategic affiliations with content
providers to expand our libraries, similar to our activePress content
affiliations with Blackwell Science and the NEW ENGLAND JOURNAL OF MEDICINE. In
addition, we intend to pursue exclusive strategic affiliations with content
providers to produce additional unique content, similar to our arrangement to
produce a consumer version of the NEW ENGLAND JOURNAL OF MEDICINE with the
Massachusetts Medical Society. We also plan to pursue strategic affiliations
with companies that offer complementary technologies, products and services,
such as Web site design and development firms, electronic medical records
providers and online prescription information and transaction service companies.

    CONTINUE TO GROW INTERNATIONALLY.  Interest in obtaining reliable healthcare
information is universal. We believe that a significant opportunity exists to
establish HealthGate as the premier supplier of healthcare information over the
Internet in markets outside the United States. Building upon the expertise
gained from the May 1998 launch of our www.healthgate.co.uk Web site, which was
specifically developed for United Kingdom users, we intend to establish
additional HealthGate country specific Web sites. Our strategy includes
licensing and creating content of specific interest to a particular country's
users, in addition to providing internationally recognized English language
sources of medical information, such as MEDLINE, and customizing and translating
the user interface into the local language. In addition, we plan to continue
syndicating portions of our content libraries to online providers in foreign
markets. For example, we have established relationships with online providers in
Italy and Australia who are providing co-branded HealthGate syndicated content
as part of their product offerings.

HEALTHGATE CONTENT

    We believe we offer professionals, patients and consumers one of the most
reliable, objective, comprehensive and up-to-date collections of health and
medical information available on the Internet, with presently over 27 million
different pages of healthcare information from approximately 300 sources. Our
content libraries are updated regularly with the latest available health and
medical information, on a daily, weekly or monthly basis, or as appropriate. We
segment our content libraries into appropriate collections to facilitate access
for professionals, patients and consumers. However, content from any collection
is available to any type of user under a variety of pricing structures. For
example, a patient who might typically access one of our free Healthy Living
Webzines for general information about a particular medical condition, illness
or disease is also able to access relevant articles in the
professionally-oriented NEW ENGLAND JOURNAL OF MEDICINE for a one time
transaction fee in order to explore the most recent and authoritative scientific
studies of that condition, illness or disease.

                                       49
<PAGE>
    Generally, certain licensed content, including MEDLINE, CANCERLIT and
AIDSLINE, is free to users throughout the HealthGate Network. Other licensed
content, including PsycINFO, CINAHL and the EMBASE Cardiology Consultant, is
accessible for a fee on a transaction specific basis or through subscription
plans. In order to meet the needs of their communities of users, CHOICE Web site
clients and licensees of our syndicated content pay us to make selected portions
of our libraries available to their users.

    We compile our online libraries in three ways: (1) licensing content from
healthcare and medical information providers; (2) developing proprietary
in-house content; and (3) licensing content from our activePress publishing
clients in conjunction with providing these clients with Web site development
and hosting services. These categories of content are described in the following

HEALTHGATE PROPRIETARY CONTENT

    This category currently includes eleven Web-based consumer health magazines
we produce called Healthy Living. The Webzines in the Healthy Living series
cover subjects such as men's health, women's health, parenting, nutrition,
travel medicine, sexuality, sports medicine, mental health, prescription and
over-the-counter drugs, alternative health and aging. Articles for these
publications are written by medical writers, physicians, dentists, dieticians
and nurses exclusively for us. These articles discuss current health trends,
newly published research findings, health-related lifestyle issues and late
breaking topics recommended by the Healthy Living Editorial Board. This
Editorial Board is comprised of five physicians affiliated with institutions
including the Harvard University School of Medicine, Boston University School of
Medicine, Massachusetts General Hospital and Dana Farber Cancer Institute. In
order to assure accurate and high quality content, all articles are reviewed
prior to publication by medical editors and by our Editorial Board. Several
Healthy Living Webzines have been recognized for their quality by the American
Medical Writers Association, Tufts University School of Nutrition, Lycos and the
Disney Go Network.

ACTIVEPRESS CONTENT

    This category currently includes the NEW ENGLAND JOURNAL OF MEDICINE,
published by the Massachusetts Medical Society, and all medical, scientific and
technical journals published by the worldwide publishing units of Blackwell
Science. Through our activePress service, we convert these journals for delivery
through the Internet and provide access to the converted journals by developing
and hosting these publishers' Web sites. In addition to being paid a fee for our
activePress development, implementation and hosting services, we receive the
right to distribute these journals through our www.healthgate.com and
www.healthgate.co.uk Web sites. We are also able to distribute the Blackwell
Science journals throughout the rest of the HealthGate Network.

STRATEGIC AFFILIATIONS AND RELATIONSHIPS



    We believe that strategic affiliations and relationships enable us to
acquire content more rapidly, develop and further distribute our products and
services, generate additional traffic on our own Web sites and CHOICE Web sites,
enhance the HealthGate brand and capitalize on additional revenue opportunities.
We have entered into strategic affiliations and relationships for healthcare
content, related products and services, marketing and online distribution and
syndication with the following companies:



CONTENT




    BLACKWELL SCIENCE, LTD.  Through our activePress service, we are the
exclusive developer on the Web of a collection of 200 full text journals for
Blackwell Science. Blackwell Science is the largest publisher of medical
societies' journals and one of the world's largest medical publishers. We have
converted and currently offer online all 200 peer reviewed journal titles
covered by our initial agreement with Blackwell Science. As part of this
service, we link these journals with the MEDLINE bibliographic database and make
them available to Blackwell Science's individual and institutional subscribers
through the www.blackwell-synergy.com Web site, developed and hosted by us. Our
hosting services include storing, maintaining and updating all converted
journals on our computer system, providing links between these journals and
other relevant databases, providing secure transaction processing through the
Web site and managing advertising and sponsorship for the Web site. In addition
to the revenue derived from the development and hosting of the
www.blackwell-synergy.com Web site, we receive a fee for each online subscriber
to a Blackwell journal and a transactional fee for each Blackwell journal
article purchased through the HealthGate Network. We have the right to syndicate
these journals throughout the HealthGate Network and share revenue from
syndication with Blackwell Science. In September 1999, we entered into a new
two-year activePress agreement to expand and extend our activePress relationship
with Blackwell Science through December 2001. Under the terms of this new
agreement, effective January 1, 2000, we will enhance Blackwell Science's Web
site and convert and bring online an additional 72 full text journals.


    NEW ENGLAND JOURNAL OF MEDICINE.  In April 1999, we entered into an
agreement with the Massachusetts Medical Society, publisher of the NEW ENGLAND
JOURNAL OF MEDICINE, the most cited publication in medicine, to be the exclusive
developer and host of an enhanced Web site for the JOURNAL using our activePress
service. Through this enhanced Web site, developed using our activePress
service, the JOURNAL will offer electronic subscriptions and be able to provide
individual article delivery and links to the MEDLINE bibliographic database,
thereby improving reader access to this important resource. As part of this
agreement, when this enhanced Web site is re-launched, we will have the right to
distribute the JOURNAL through our own Web sites, through CHOICE Web sites, and,
with the prior approval of the publisher, through syndication to third party Web
sites. In addition to the revenue derived from the development and hosting of
this Web site, we receive a fee for each online subscriber to the JOURNAL and a
transactional fee for each JOURNAL article purchased by a non-subscriber. The
initial term of our activePress agreement with the Massachusetts Medical Society
runs through April 2001 and is renewable annually by mutual agreement. Until the
JOURNAL's enhanced Web site is re-launched, which we currently expect to occur
by the end of 1999, HealthGate users and JOURNAL subscribers are able to access
the JOURNAL's existing Web site through a link from HealthGate's own Web site.
During this interim period, HealthGate users will be able to access various
portions of the JOURNAL's existing Web site, but only JOURNAL subscribers will
be able to access the past issues of the JOURNAL available online.


    CONSUMER VERSION OF THE NEW ENGLAND JOURNAL OF MEDICINE.  In June 1999, we
entered into an agreement with the Massachusetts Medical Society to create a
Web-based consumer version of the NEW ENGLAND JOURNAL OF MEDICINE. Under this
agreement, we will be the exclusive distributor of this unique version of the
JOURNAL, although, beginning six months after delivering the first issue to us,
the Society

                                       52
<PAGE>
may make this version of the JOURNAL available on its own Web sites. We will pay
an annual fee of $500,000 for the Society to re-write all original articles
appearing each week in the JOURNAL in common, non-technical language. We, in
turn, plan to use our technology platform to adapt and integrate this content
and to link it to MEDLINE, to drug databases, to other content sources and to
relevant sites on the Web. We currently intend to make the publication available
through subscription. We plan to sell both targeted advertising and sponsorship
on these pages. Revenue derived from the consumer version of the JOURNAL will be
shared by the Society and us. We expect to release the consumer version of the
JOURNAL in early 2000. The initial term of this agreement is two years from the
date on which the Society delivers the first issue to us and is renewable for
two additional 18 month periods by mutual agreement.


PRODUCTS AND SERVICES



    PHYSICIANS WORLD COMMUNICATIONS GROUP.  We have an agreement with Physicians
World Communications Group, an independent medical education company in the
United States. Professional Postgraduate Services, a division of Physicians
World, is accredited by the Accreditation Council for Continuing Medical
Education to offer Category 1 Continuing Medical Education (CME) credit.
Physicians World pays us to format original CME programs for the Web to enhance
the ease of use and quality of the educational experience by adding
interactivity, graphics and audio and video components. We share the revenue
with Physicians World generated from physicians purchasing these programs
through the HealthGate Network. We have agreed to develop CME programs for Web
distribution exclusively with Physicians World, with the exception of CME
programs developed by Boston University School of Medicine and online continuing
healthcare professional education programs related to our recent arrangement
with HealthStream, Inc.



    BOSTON UNIVERSITY SCHOOL OF MEDICINE.  We have an agreement with Boston
University School of Medicine to distribute Continuing Medical Education
programs developed by the School of Medicine through our own Web sites, through
our CHOICE Web sites and through licensees of our syndicated content. Boston
University is accredited by the Accreditation Council for Continuing Medical
Education to offer Category 1 CME credit. We include 34 different CME programs
from Boston University in our content libraries. We plan to develop additional
programs with Boston University through this relationship.



    HEALTHSTREAM, INC.  In September 1999, we entered into a continuing
education services agreement with HealthStream, Inc., a provider of computer and
Web-based education and training services for the healthcare industry. This
agreement provides for the creation of a Web site, hosted by HealthStream and
co-branded by both HealthStream and HealthGate, and allows us to distribute
HealthStream's Category 1 Continuing Medical Education programs and other
accredited continuing education programs for nursing and allied health
professionals to users of our www.healthgate.com Web site and our co-branded
CHOICE Web sites. We expect that this HealthStream/HealthGate Web site will be
operational by the end of the first quarter of 2000. We will share the revenue
generated from physicians and other healthcare professionals purchasing these
online programs. As part of this agreement, HealthStream will pay us a minimum
of $250,000 annually for, among other things, sponsorship on our own Web sites
and on our co-branded CHOICE Web sites. The initial term of our continuing
education services agreement with HealthStream is two years and is renewable
annually by mutual agreement. Pursuant to a separate marketing services
agreement with HealthStream we have committed to spend $100,000 annually to
promote the co-branded HealthStream/HealthGate Web site. We have also agreed to
purchase a minimum of $150,000 of CME courses annually from HealthStream for
distribution to healthcare professionals for promotional purposes. We expect to
record revenue under this arrangement net of any amounts made to purchase CME
courses.


    Physicians take CME courses in order to: (1) comply with state licensure
requirements; (2) qualify for lower insurance premiums; and (3) fulfill
membership requirements of professional associations.

                                       53

Generally, Category 1 CME courses are considered by most physicians to be more
valuable than other types of CME courses. Approximately 20 hours of Category 1
credit is required annually by most states for physician re-licensure.


MARKETING AND DISTRIBUTION


    COLUMBIA INFORMATION SYSTEMS, INC.  In November 1999, we entered into a
three-year development agreement with Columbia Information Systems, Inc., a
subsidiary of Columbia/HCA Healthcare Corporation, to design, develop and
maintain customized, co-branded CHOICE Web sites for up to 280 Columbia/HCA
hospitals and affiliates. In addition, we will design, develop and maintain a
health portal site for Columbia Information Systems. We will also provide
content and services to both Columbia Information Systems' health portal site
and its customized, co-branded CHOICE Web site product. The agreement provides
for an annual license fee of $3.5 million to be paid by Columbia Information
Systems for all products and services that we provide under the agreement. The
annual license fee is subject to prospective adjustment in certain events,
including the delivery by us of fewer than 200 or more than 280 customized,
co-branded CHOICE Web sites. However, if we deliver fewer than 200 customized,
co-branded CHOICE Web sites, the adjustment is limited to a minimum annual
license fee of $2.5 million. In addition, we will share advertising and
sponsorship revenues and certain e-commerce revenues. The agreement may be
terminated without cause by Columbia Information Systems on June 1, 2001, upon
payment of a $1.0 million termination fee to HealthGate. We expect to have the
customized co-branded CHOICE Web site product ready for initial distribution in
the fourth quarter of 1999 and to have the health portal site operational in the
first quarter of 2000.


    In November 1999, we entered into a separate three-year marketing and
reseller agreement with Columbia Information Systems under which Columbia
Information Systems agreed to endorse us as the preferred provider of patient
and consumer oriented health content for Web sites owned or operated by
Columbia/HCA hospitals and affiliates. We believe as an endorsed preferred
provider, it is more likely that Columbia/HCA hospitals and affiliates will use
our products and services. The agreement provides us, among other things, the
right to make a first offer to provide services for adding content to the
Columbia Information Systems' health portal site and any Web site owned or
operated by or affiliated with Columbia Information Systems or Columbia/HCA. We
also have the exclusive right to host on the Internet content provided to us by
healthcare providers owned, controlled or operated by any entity owned or
controlled by Columbia/HCA Healthcare Corporation. To date, we have not hosted
Columbia/HCA content. Further, Columbia Information Systems may, for a
commission, market and sell our CHOICE Web site product to entities unaffiliated
with Columbia/HCA, subject to our approval.



    In connection with this agreement, we have issued a warrant to CIS Holdings,
Inc. for the purchase of up to 1,941,035 shares of our common stock. The warrant
has a term of three years and will be exercisable on the earlier of the
consummation of this offering, certain private placements of securities, a sale
of HealthGate or March 31, 2000. The exercise price per share will be equal to
our initial public offering price. If an initial public offering is not
completed by March 31, 2000, the exercise price per share will be the common
equivalent price per share received by HealthGate in its next qualifying private
placement. If neither an initial public offering nor a qualifying private
placement occur before March 31, 2000, the exercise price per share will be
adjusted to $3.46 on March 31, 2000. In the event we issue common stock or other
equity or debt instruments which are convertible into common stock for an amount
less than the current exercise price, then the exercise price and number of
shares of this warrant will be adjusted accordingly. These adjustment provisions
will terminate upon the completion of an initial public offering. If HealthGate
is sold prior to the consummation of its initial public offering or a qualifying
private placement, the exercise price per share will be adjusted to $3.46 per
share effective with such sale. The shares of common stock issuable under the
warrant will have registration rights similar to those granted to holders of our
Series A, B, C and D Stock. We


                                       54
<PAGE>

expect to record the fair value of this warrant as marketing and distribution
rights, and amortize the value as a sales and marketing expense on a
straight-line basis over the three year contractual term of the related
agreement. Based on the currently anticipated offering price range, we expect
the value of this warrant to range from approximately $10.7 million to
$13.1 million. If the initial public offering price is above the currently
anticipated offering price range, this value will be higher.



    SNAP! LLC AND XOOM.COM, INC.  In October 1999, we entered into a three-year
strategic alliance agreement with Snap! LLC and Xoom.com, Inc. Snap and Xoom are
expected to combine with certain assets of NBC to form NBC Internet, which
combination is expected to occur prior to December 31, 1999. Under our strategic
alliance agreement, Snap will provide the services, described below, to promote
our name, our www.healthgate.com Web site, our co-branded CHOICE Web sites and
the products and services we offer, and we will design, develop and host a
co-branded Snap/HealthGate Web site, which will provide the features and
functionality of our www.healthgate.com Web site. After the co-branded
Snap/HealthGate Web site is brought online, which is scheduled to occur
following our payment of fees to Snap with a portion of the proceeds from this
offering, Snap will feature us as the anchor tenant, giving us the exclusive
right to be the most prominent content provider, for seven of the major content
areas within the Health Channel which is part of Snap's Web site located at
www.snap.com. Both Snap's Health Channel and the co-branded Snap/HealthGate Web
site will contain portions of our content libraries and link to our
www.healthgate.com Web site to provide users access to our complete content
libraries. If Snap adds new content areas to its Health Channel, we have a right
of first offer to provide health-related content to the new areas as long as our
content continues to be of at least the same quality as that of our top
competitors. We will also have the exclusive right to sell advertising on the
co-branded Snap/HealthGate Web site. Snap will display various promotions for
us, at discounted rates, designed to deliver click-throughs to the co-branded
Snap/HealthGate Web site, our co-branded CHOICE Web sites and our
www.healthgate.com Web site from Snap's www.snap.com Web site and other Web
sites affiliated with Snap. Snap has agreed to deliver a minimum number of these
promotions during each year of the agreement, but it will be able to satisfy
these minimums by displaying them within the six months following the relevant
year. If these minimums are not delivered within those six months, Snap must
refund a pro rata portion of the fee paid by us under the agreement. In
addition, Snap will create and run a series of television ads on the NBC
television network, local television stations or cable services featuring in
part the health-related content areas of its Web sites and our name, brand or
services.



    In exchange for the services provided to us by Snap during the first year of
the agreement, we have agreed to pay Snap a minimum fee of $10.0 million and
500,000 shares of our common stock, plus a $250,000 production and content
integration fee. The $10.3 million cash component of the first year minimum fee
due to Snap is payable within thirty days after the registration statement filed
with the SEC in connection with this offering is declared effective by the SEC.
We have agreed to pay Snap minimum fees of $15.0 million in each of the second
and third years of the agreement for the services provided to us by Snap in
those years. We have also agreed to pay Snap up to an additional $5.0 million in
the first year, $10.0 million in the second year and $15.0 million in the third
year of the agreement if Snap delivers more than a minimum number of
click-throughs to the co-branded Snap/ HealthGate Web site in the respective
years. Either Snap or we may terminate this agreement if the other party commits
a material breach. If Snap terminates the agreement based on a material breach
by us, including non-payment, insolvency, or failure to deliver or timely update
content, we have agreed to continue to pay Snap 55% of all fees payable by us
under the agreement for the remaining term of the agreement. If Snap and Xoom do
not combine with certain assets of NBC to form NBC Internet on or before March
31, 2000, we may terminate the agreement and Snap must return to us all
payments, including the common stock we have issued to them as partial payment
for the first year minimum fee, made prior to the termination.


                                       55
<PAGE>

    As part of this agreement, Xoom shall have the right to use information we
collect on users of the co-branded Snap/HealthGate Web site and, with our
consent, users of our www.healthgate.com Web site for Xoom's direct marketing
efforts. In exchange, Xoom will send up to one promotional email per month for
us. Xoom will also pay us a fee for each unique user who purchases a product via
e-commerce as a result of a Xoom email to individuals for whom we provided user
information to Xoom from our user database.


    GE MEDICAL SYSTEMS.  In June 1999, we entered into a development and
distribution agreement with GE Medical Systems, the medical diagnostic equipment
and services division of General Electric Company. Under the terms of this
agreement, we will develop and host GE Medical Systems branded enhanced versions
of our CHOICE Web site product. GE Medical Systems will have an exclusive
worldwide right to sell these enhanced CHOICE Web sites to hospitals and other
patient care facilities. GE Medical Systems will also have the exclusive right
to sell our standard CHOICE Web site product to a select group of hospitals and
other patient care facilities. In addition, GE Medical Systems will have the
non-exclusive right to sell our standard CHOICE Web site product to other
healthcare institutions, subject, in certain cases, to our prior consent. GE
Medical Systems has a worldwide customer base of hospitals and other patient
care institutions and a sales and marketing organization dedicated to
healthcare. GE Medical Systems' customer base presents an attractive audience
for both our own CHOICE Web sites and the enhanced GE Medical Systems branded
versions of our CHOICE Web sites. Revenue derived from CHOICE Web sites sold by
GE Medical Systems will be shared by GE Medical Systems and us. The initial term
of our development and distribution agreement with GE Medical Systems is one
year and is renewable annually by mutual agreement.


    In connection with the development and distribution agreement, we issued to
General Electric Company a warrant for the purchase of up to 1,189,800 shares of
our common stock. The warrant has a term of five years, an exercise price of
$9.49 per share and is immediately exercisable. In the event HealthGate issues
common stock or other equity or debt instruments which are convertible into
common stock for an amount less than the current exercise price of this warrant,
then the exercise price and number of shares issuable under this warrant will be
adjusted accordingly. These adjustment provisions will terminate upon the
completion of an initial public offering. However, if we fail to complete an
initial public offering, a private placement of securities, or a sale of
HealthGate by December 31, 1999, the exercise price will be adjusted to $3.46
per share on January 1, 2000. In the event the exercise price of this warrant is
adjusted, its fair value will increase. The shares of common stock issuable
under the warrant will have registration rights similar to the registration
rights provided to GE Capital Equity Investments, Inc. and Blackwell Science.
See "Shares Eligible for Future Sale--Registration Rights."



    The fair value of the warrant of $10.3 million was recorded as marketing and
distribution rights in assets, and will be amortized as sales and marketing
expense on a straight-line basis over the one year contractual term of the
related development and distribution agreement. During the nine months ended
September 30, 1999, amortization expense totaled $2,941,000. In the event the
exercise price of the warrant is adjusted downward, its fair value will
increase.



    DATA GENERAL CORPORATION.  We have a marketing relationship with Data
General Corporation, an information technology products and services company
which has recently been acquired by EMC Corporation. Data General has a current
customer base of approximately 2,500 hospitals and healthcare institutions
worldwide and a sales and marketing group dedicated to healthcare. Data
General's healthcare customer base presents an attractive target market for our
CHOICE Web sites. As a value added reseller, Data General will offer our
co-branded CHOICE Web site product to complement the suite of products and
services that it currently offers to its customers, which products and services
include electronic medical records services, imaging and archival software and
Web-authoring tools. Data General will distribute our CHOICE Web site product to
its customers by purchasing it from us and then reselling it to specific
enterprises based on a CHOICE end-user license


                                       56
<PAGE>

agreement entered into between HealthGate and the specific enterprise. We have
granted Data General an exclusive right to resell our CHOICE Web site product to
a defined group of its current customers until December 31, 1999. This exclusive
right may be extended if Data General achieves sales targets, to be determined
by mutual agreement, by that date. Data General has agreed that, during the term
of the agreement, it will not market any other products or services that are
similar to our CHOICE Web site product. The initial term of our agreement with
Data General runs through June 2001 and is renewable for one additional year by
mutual agreement.


SYNDICATION




    We have syndication relationships with three high-traffic, health-related
Web sites to distribute portions of our content libraries through licensing
agreements. Our present syndication relationships are with WebMD, Inteli-health
and the American Medical Association. In addition to providing licensing fees to
us, these agreements, in most cases, provide for sharing advertising and
sponsorship revenue generated through these third party Web sites. The license
fees from syndicating our content are classified as services revenue. Through
licensed syndication, we are able to leverage the user bases of these HealthGate
Network Web sites to drive additional traffic to our content libraries in order
to further increase awareness of the HealthGate brand and develop additional
advertising and sponsorship and e-commerce revenue opportunities. Our name,
embedded with a link to our www.healthgate.com Web site, is displayed on each
page viewed by the user accessing our syndicated content through third party Web
sites.


HEALTHGATE'S PRODUCTS AND SERVICES

    We have established four distinct product and service offerings: (1) our own
Web sites; (2) CHOICE Web sites; (3) content syndication; and (4) activePress
services. The target groups for these products and services cover a broad
spectrum of customers and users, providing multiple revenue sources, as
summarized in the following chart.

</TABLE>

    In addition, we have established an alliance with Snap and Xoom to supply
portions of our content libraries to users of the Snap Web portal site and to
design, develop and host a co-branded Snap/ HealthGate Web site. We anticipate
that our relationship with Snap will drive traffic to the co-branded
Snap/HealthGate Web site, resulting in additional traffic to our own
www.healthgate.com Web site and our co-branded CHOICE Web sites that we host for
hospitals. We believe that additional traffic to these sites will increase
awareness of the HealthGate brand and develop additional advertising,
sponsorship and e-commerce revenue opportunities.

THE WWW.HEALTHGATE.COM AND WWW.HEALTHGATE.CO.UK WEB SITES

    We provide healthcare information, products and services through our own Web
sites, www.healthgate.com in the United States and www.healthgate.co.uk in the
United Kingdom. The www.healthgate.com Web site, targeted to a wide range of
users, was the first to provide free Web access to the complete MEDLINE
database. This site provides a range of medical information, from basic
background information on general health matters, wellness, illnesses and
diseases to in-depth scientific research on specific medical conditions, from a
variety of licensed and proprietary content sources. The content available on
this site is divided into collections targeted to professionals, patients or
consumers. However, content from all collections is available to any type of
user. For example, a patient can access an article on a specific medical
condition in the professionally oriented NEW ENGLAND JOURNAL OF MEDICINE.
Content sources include patient education and wellness information,
bibliographic databases, Continuing Medical Education programs and decision
support materials. Presently, our consumer information is accessible through
www.healthgate.com and www.bewell.com, our companion consumer Web site. We plan
to combine our www.bewell.com Web site with our www.healthgate.com Web site by
the end of 1999.

    The healthgate.co.uk site, launched in May 1998, is our first
country-specific Web site. In addition to internationally recognized sources of
medical information, such as MEDLINE, this site provides access to content of
specific interest to users in the United Kingdom. We use our existing technology

                                       58
<PAGE>
platform to provide easy access to the information on this site. We also use our
technology platform to conform our content to local cultural and language
nuances.

    Users may access portions of our content libraries on our own Web sites for
free. Other licensed content, such as PsycINFO, CINAHL, the EMBASE Cardiology
Consultant, and articles from the journals we make available, are available for
a fee on a transaction specific basis.

CO-BRANDED CHOICE WEB SITES FOR ENTERPRISE CLIENTS

    Our CHOICE Web sites are customized, co-branded Web sites linked to an
enterprise's own Web site to provide an enterprise with the ability to offer
online healthcare information to its communities of users. We market CHOICE Web
sites to the following types of enterprises:

    - HEALTHCARE INSTITUTIONS--Healthcare Institutions include hospitals,
      managed care organizations and physician groups. These institutions may
      wish to provide online healthcare information to their staff and patients
      and better market their services to the local community.

    - INTEGRATED DELIVERY NETWORKS--Integrated Delivery Networks are networks of
      hospitals and clinics. Integrated Delivery Networks can utilize CHOICE Web
      sites as part of their suite of services to achieve better brand
      recognition while still maintaining the personalized level of service from
      each individual component in their network.

    - CORPORATE ENTITIES--Our CHOICE Web sites enable businesses to license our
      content to complement their own information that they distribute on the
      Web and the products and services they sell on the Web. In addition, our
      CHOICE Web sites enable any business to provide its employees health and
      wellness information through corporate intranets and extranets. By
      providing information for health and wellness programs, businesses may be
      able to lower their direct healthcare costs, reduce sick days and increase
      worker productivity.

    - COLLEGES AND UNIVERSITIES--Students, faculty and staff can use our CHOICE
      Web sites to access information needed for research papers, theses,
      dissertations and for information concerning their own health.

    We establish co-branded Web sites customized for our CHOICE clients to
provide healthcare information from our content libraries and related services
tailored to the needs of the specific enterprise's users. Our content and
services are offered to the CHOICE client in separate modules so that the
enterprise client can choose to have all or individual segments of our content
libraries and services available through its CHOICE Web site. The three basic
content modules divide our content libraries into:

    - a professional series, which offers clinically oriented content such as
      MEDLINE;

    - a patient series, which includes 3,000 different condition-specific
      informational brochures; and

    - a consumer series, featuring general introductory magazine articles from
      our Healthy Living Webzines.

    We are continually developing additional service modules for our CHOICE
clients. For example, we recently added the following new module options:

    - PRINTING MODULE FOR PATIENT BROCHURES. Allows printing of customized
      patient information brochures using content from our content libraries
      with a signature look and feel unique to the specific CHOICE customer,
      using customized headers and footers, including organization name, logo,
      physician name, contact information and other appropriate information.

                                       59
<PAGE>
    - RESOURCE LOCATOR MODULE, WITH CONTENT SENSITIVE LINKS. Allows information
      retrieval on any of the hospital's physicians, facilities, special
      services or programs, using the hospital's or independent information
      databases, such as OneSource, a database of physicians.

    We further customize the CHOICE Web site by designing it to be a seamless
component of the enterprise's existing Web site. We have developed a number of
templates for CHOICE Web site design from which we are able to conform the
design with the enterprise's own Web site. Because we use a standard format for
our content and have developed flexible Web site templates, we are generally
able to bring CHOICE Web sites online within 10 to 15 business days of signing
an agreement with a CHOICE client.

    To date, we have sold CHOICE Web sites under agreements that provide for
development, implementation and hosting fees to be paid by the enterprise client
for a term of one to three years. As of September 30, 1999, we had delivered 39
co-branded CHOICE Web sites providing health information to 32 hospitals,
including Swedish Medical Center (Seattle, Washington), St. Joseph's Hospital, a
unit of Carondelet Health Systems (Kansas City, Missouri) and Winchester
Hospital (Winchester, Massachusetts), one university, Indiana State University
(Terre Haute, Indiana), one corporate wellness center, Data General Corporation,
and 5 businesses, including GlobeRx.com, Handbag.com, Med-Emerg International,
Nichols TXEN and ProxyMed. The CHOICE client can also choose to participate in
advertising and sponsorship and e-commerce opportunities for its CHOICE Web
site. The revenue from these opportunities is allocated between the CHOICE
client and us. We sold 14 of our initial CHOICE Web sites on a promotional
basis, under which we guarantee certain amounts of advertising and sponsorship
revenue to these CHOICE sites, generally in amounts equal to the fees to be paid
by these customers. We intend to market our CHOICE Web site product to
additional target enterprise clients including Integrated Delivery Networks, but
have not yet sold a CHOICE Web site to this target client group.

        Professionals can access databases, reference materials, the latest news
    and CME courses to assist in patient care and in research.

        Patients can search 3,000 different brochures for information on
    specific, illnesses and conditions.

        Health-conscious consumers can access HealthGate's Webzines to help them
    lead a healthier lifestyle.]

CONTENT SYNDICATION


    We selectively syndicate portions of our content libraries to other
high-traffic, health-related Web sites pursuant to licensing agreements. Through
syndication, we are able to drive additional traffic to the HealthGate Network
in order to further increase awareness of the HealthGate brand and develop
additional advertising, sponsorship and e-commerce revenue opportunities. Our
name, embedded with a link to our www.healthgate.com Web site, is displayed on
each page viewed by the user accessing our syndicated content through third
party Web sites. In addition to generating revenue from licensing fees for the
syndication of our content, most of these syndication arrangements provide for
sharing advertising and sponsorship revenue generated through these Web sites.
To date, however, we have only realized revenue from these licensing fees and
have not recognized any revenue from advertising and sponsorship or e-commerce
on these Web sites. Presently, we have syndication affiliations with WebMD,
Inteli-health and the American Medical Association. For the nine months ended
September 30, 1999, our content syndication arrangement with WebMD accounted for
12% of our total revenue. We are presently negotiating with WebMD concerning the
terms and provisions of the annual renewal of the agreement which was
contemplated for October 30, 1999. During our negotiations, we are continuing to
provide content to WebMD under the same terms as provided under our earlier
agreement. We can not assure you that we will be able to reach mutually
agreeable terms of renewal with WebMD and, if we do not, we may lose WebMD as a
customer.


ACTIVEPRESS SERVICE FOR PUBLISHERS

    Our activePress service, which was launched in 1998, provides a full service
Web-based solution to publishers and other parties that wish to offer Web-based
access to print materials or databases. Through this service, healthcare
publishers can reach an Internet audience through Web sites that we develop and
host. The activePress service utilizes our existing technology platform and
expertise to develop and host Web sites, convert the publisher's information for
the Internet and link the published information with relevant databases, such as
MEDLINE, enabling the publisher to deliver an enhanced electronic version of the
print publication to subscribers, institutions and authorized third parties. As
a result of these relationships, we also hold Web hosting rights to these
publications, requiring anyone seeking an online article from one of these
journals to access the publication either through the activePress enabled site
or through the HealthGate Network.

    activePress service revenue includes fees for converting, hosting and
storing information and providing development, support and maintenance.
Additionally, transactional revenue is derived from fees associated with users'
access to the publisher's content. These fees, which may be paid by the user or
the publisher, are derived on a per subscriber, per page or per article basis.


    Blackwell Science and Massachusetts Medical Society, the publisher of the
NEW ENGLAND JOURNAL OF MEDICINE, are currently clients of our activePress
service. See "--Strategic Affiliations and Relationships--Content."


WEB PORTAL ALLIANCE


    We will provide access to selected portions of our content libraries to
users of Snap, a Web portal site. Web portal sites aggregate content from
various sources and make the content, or links to the content, available on a
single Web site, organized into related groupings of content, typically called
channels. Following our payment of fees to Snap with a portion of the proceeds
from this offering, HealthGate will be the anchor tenant, or most prominent
provider of healthcare information, for seven of the major content areas of
Snap's Health Channel. Our name will be prominently displayed throughout the
Snap Health Channel. Users of the Snap Health Channel will see selected portions
of our content libraries on the Snap Web site. When Snap users wish to access a
complete article, not just the portion available on the Snap Web site, they will
link from the Snap Health Channel to a co-


                                       62
<PAGE>

branded Snap/HealthGate Web site that we will design, develop and host or our
www.healthgate.com Web site.


    We anticipate that our relationship with Snap will drive traffic to the
co-branded Snap/HealthGate Web site, resulting in additional traffic to our own
www.healthgate.com Web site and our co-branded CHOICE Web sites that we host for
hospitals. We believe that additional traffic to these sites will increase
awareness of the HealthGate brand and develop additional advertising,
sponsorship and e-commerce revenue opportunities. In addition to promoting the
HealthGate brand, we will have exclusive rights to sell advertising on the
co-branded Snap/HealthGate Web site.

ADVERTISING AND SPONSORSHIP

    The depth and breadth of our content and the variety of our distribution
channels developed for specific audiences of healthcare consumers offer
advertisers and sponsors opportunities to target their messages to particular
user groups. Advertisers may target groups by demographics such as gender and
geographic location or advertise more broadly to the general population of
health information users. The HealthGate Network's underlying technology
platform recognizes a wide range of information about individual users. This, in
turn, allows us to selectively target banner advertisements to users viewing
specific topics or content sources. For example, we can place a banner
advertisement for Tylenol on users' screens searching our content for
information on headaches. We also intend to offer advertisers the opportunity to
employ one-to-one advertising or niche marketing. This type of advertising
allows advertisers to target individual users based on registration details,
both through banner advertising and through e-mail.

    We track banner advertising impressions and click-through rates for these
advertisements and issue a NetGravity Traffic Report weekly to our advertisers.
Statistics provided to both potential and current advertisers about our traffic
patterns are audited by Audit Bureau of Circulation Interactive to assure
accuracy.

    Recent advertisers on the HealthGate Network, predominantly on our own Web
sites, have included the following pharmaceutical companies, manufacturers of
consumer and health goods, providers of health information and others.

    - Pharmaceutical companies, including American Home Products (Enbrel),
      Johnson & Johnson (Tylenol and Procrit), Pfizer (Zyrtec) and Biogen
      (Avonex);

    - Consumer health goods, including HealthShop.com (vitamins and
      supplements), SelfCare (health aids), Dr. Scholls (health aids) and
      CVS.com (online drugstore);

    - Providers of health information, including Medical Economics (books) and
      MedBookStore.com (books); and

    - Others, including Entrepreneur Magazine, the U.S. Air Force, the U.S.
      Army, NextCard and Ameritrade.


    In October 1999, approximately 8.5 million advertisements were displayed on
our own Web sites, approximately 4.1 million of which were sold for cash to
advertisers, approximately 54,000 of which were used to fulfill barter
arrangements and the remainder of which were used for internal marketing
purposes.


    We offer sponsorship opportunities to companies that wish to target specific
topics, content sources or CHOICE Web sites. Sponsorships are designed to
support broad marketing objectives, including branding and product
introductions, generally on an exclusive basis. For example, sponsorships allow
businesses to have their name, message or products appear together with a link
to their own Web site in every page of a Healthy Living Webzine, a CHOICE Web
site or a condition specific Wellness Center. Sponsorships are sold for specific
periods of time and portions of the Web site.

                                       63

    The following screen illustrates opportunities for advertising and
sponsorship within a co-branded CHOICE Web site:

   [Screen shot of a co-branded CHOICE Web site, with lines indicating logo,
      advertising, sponsorship and additional feature areas of the page.]

E-COMMERCE

    Currently, we use e-commerce to provide portions of our licensed content,
including PsycINFO, CINAHL, the EMBASE Cardiology Consultant and full-text
journals via the activePress service on a pay per view or transaction fee basis.
In addition, we provide users the opportunity to purchase medical textbooks and
other print products from MedBookStore, a Web-based medical bookstore offered by
Medsite Publishing, and photocopies of articles not available from our
collection of full-text journals from Infotrieve, a document delivery service.
Also, users can subscribe to certain fee-based content sources on a monthly
basis.

    We believe that significant opportunities exist to provide additional
healthcare related products to professionals, patients and consumers using our
technology platform and the HealthGate Network. In order to pursue these
opportunities, we are exploring options for expanding the products and services
currently offered using e-commerce.

SALES AND MARKETING

    We sell our products and services through our own direct sales force and
through value added resellers. Our direct sales force consists of two teams: (1)
CHOICE Web site sales; and (2) advertising and sponsorship sales. We divide the
United States and Canada into seven direct sales regions for CHOICE Web site
sales and assign direct sales representatives to each region. Our CHOICE Web
site sales team consists of two groups, outside sales and inside sales. The
outside sales group is responsible for delivering focused and targeted marketing
for CHOICE Web sites, content syndication customers and other customers,
increasing consumer awareness of the HealthGate brand and establishing campaigns
to develop brand loyalty. Our inside sales group is responsible for facilitating
the entire sales process, identifying leads through telemarketing and supporting
our customers. The inside sales group's support functions include maintenance of
customer and prospect databases, online demonstration sessions, preparation of
presentations and proposals and development of relationships with current and
future clients. Our advertising and sponsorship sales efforts are conducted from
our headquarters in Burlington, Massachusetts.

    In addition to our direct sales force, we have established a value added
reseller relationship with Data General. Through this relationship, we leverage
the cross selling opportunities offered by Data General's worldwide healthcare
sales force in their sales calls to their customer base of approximately 2,500
hospitals and healthcare institutions worldwide.


    In June 1999, we entered into a development and distribution relationship
with GE Medical Systems pursuant to which GE Medical Systems will be able to
sell our CHOICE Web site product and GE Medical Systems branded enhanced
versions of our CHOICE Web site product through its worldwide sales force into
its worldwide customer base of hospitals and other patient care facilities. See
"--Strategic Affiliations and Relationships--Marketing and Distribution."


    In Europe, our sales efforts are coordinated through our subsidiary,
HealthGate Europe, Limited, based in London. HealthGate Europe concentrates its
efforts on licensing our syndicated content to third parties and developing
additional activePress relationships.


    We presently market our products and services through traditional means,
including direct mail, print advertising and telemarketing. We also use
Web-based banner advertising and sponsorship on our


                                       64
<PAGE>

own Web sites, portions of the HealthGate Network and other third-party sites,
targeted linking on the HealthGate Network and e-mail alerts to registered users
of our own Web sites. Additionally, we have agreed to purchase a significant
amount of advertising and sponsorship on Snap.com and related Web sites as part
of our strategic alliance agreement with Snap, as described under "--Strategic
Affiliations and Relationships--Marketing and Distribution." We intend to
purchase additional advertising and sponsorship on certain CHOICE Web sites. We
are also considering adding radio and television advertising to our marketing
efforts.


    We expect to use a portion of the net proceeds of this offering to expand
our sales and marketing efforts. See "Use of Proceeds."

CUSTOMER SERVICE

    We are committed to providing a high level of service and support to our
clients and users. We believe that customer service is important to our ability
to attract and retain clients and users. We provide service and support via a
toll-free telephone number, e-mail and, on the Web site itself, through help
screens and Frequently Asked Questions (FAQ) areas. The customer service staff
includes medical librarians who are experienced in medical information
retrieval.

TECHNOLOGY PLATFORM

    Our technology, consisting of internally developed and commercially
available software programs, is designed to leverage the benefits of modular
components so that all elements of our various content libraries and other
databases can be channeled into one unified platform. From this platform, we can
quickly and easily adapt all of this content and other data for numerous online
applications, such as: (1) standardizing the appearance of disparate content
sources; (2) integrating advertising and sponsorship; and (3) facilitating
information retrieval for our customers and users. In addition, the modular
composition of our technology platform enables us to reuse, update, scale,
extend and replace components as needed. As content is added to our technology
platform and moves through the various modules during processing, each
individual module adds specific and unique features and functionality to the
content.

    There are three specific groups of modules: (1) Content Standardization; (2)
Content Enhancement; and (3) Content Delivery. Unless otherwise noted, all
modules are either available through the HealthGate Network or through our
activePress service. We plan to integrate modules presently available only
through our activePress service into the HealthGate Network.

CONTENT STANDARDIZATION

    CONTENT NORMALIZATION.  The content normalization module converts original
content, regardless of format supplied by the content provider, into a single,
consistent Extensible Markup Language (XML) format. XML is a markup language
used to identify structures and their roles within a document. For example,
words within a document are classified as structures. The specific words in the
document's footnotes are indicative of the role these words, or structures, have
in the document. Meta-information, or information describing the content
supplied by the provider, is retained. However, this module adds additional
tagging to the provider-supplied meta-information for use in the searching,
topics and dynamic formatting modules. The use of XML in the content
normalization module enables us to offer, through other modules, multiple
product offerings with different features, while using the same content from the
same repository.

    CONTENT ANALYSIS.  The content analysis module attaches value-added
information to content. For example, footnotes, endnotes or bibliographies from
journal articles are linked to abstracts or more detailed information found in
other content sources such as MEDLINE. Features under development include the
linking of drug trade names to a pharmaceutical source, identifying company
names and

                                       65
<PAGE>
providing appropriate links to other sources and associating content with
various conditions, illnesses or related topics.

    CONTENT MATCHING.  The content matching module integrates three separate
databases enabling them to interact and relay information to each other as a
user moves through our various content sources. The different databases are
Users, Content Sources and Usage. The content matching module tracks individual
users (Users) through the HealthGate Network, recording what content they use
(Content Source), and recording the transaction for later use (Usage).

CONTENT ENHANCEMENT

    AUTHENTICATION, ACCESS CONTROL AND E-COMMERCE.  The authentication, access
control and e-commerce module confirms a user's identity, allows the user access
to the various content sources and records any transaction or usage for that
user. This module is analogous to a content store, offering access to content on
a fee per use basis. These sales can be via a one-time credit card transaction
or through institutional access. This module allows us to package content
through different methods to different user groups using various pricing models.
For example, information from a particular journal can be sold to the user by
year, by the issue, by the article, or even by the page.

    SEARCHING.  The searching module, using our ReADER search software that
provides a natural language searching tool, enables professionals, patients and
consumers access to content without regard for the level of their expertise,
knowledge of medical terms, or knowledge of specific database searching
commands. For example, if a user searches the MEDLINE database for the common
concept "CAT Scan," the ReADER tool would translate that phrase into a search
for the medical term "Tomography, X-Ray Computed" yielding more relevant
results.

    TOPICS.  The topics module creates topic hierarchies or organizes specific
content for the professionals, patients, or consumers according to pre-defined
algorithms. Topics are created using both searching and keyword technologies.
Patient and consumer topics are organized by medical condition. Professional
topics are organized by medical specialty. Topics allow for quick access to the
latest information without requiring the user to search multiple content
sources.

    ADVERTISING.  The advertising module enables us to target specific
advertisements to individuals or groups based on demographic information, user
registration, or specific content sources. For example, a user searching for
information on headaches could be shown an advertisement for Tylenol. This
module also handles scheduling of advertisements, reporting of results to
advertisers and the placement and screening of advertisements.

    PERSONALIZATION.  The personalization module enables content to be
customized for the individual user. Among the features provided through this
module are user-managed subscriptions and commerce, e-mail updates and saved
searches. A new feature under development will allow a user to create a
customized Web page displaying only information based upon a user provided
profile. Personalization is currently available through our activePress service
and is being integrated into the HealthGate Network.

    RELEVANT INFORMATION LINKING.  The relevant information linking module
enables dynamic cross-referencing or linking among related content and features.
For example, content targeted for the physician can be linked to corresponding
patient education materials, enabling the physician to produce a customized
brochure handout, written specifically for the patient, without accessing
multiple content sources.

    COMMUNITY BUILDING.  Currently under development, the community building
module will enable users to interact and establish relationships with other
users possessing similar health-oriented interests. For example, discussion
groups can be formed around specific conditions, individual journal articles, or

                                       66
<PAGE>
treatment options. An option currently available called "Send to a Friend"
enables users to send e-mail, with a link to a specific article from content
available from HealthGate, to friends or colleagues.

    ADAPTIVE PROFILING.  Currently under development, the adaptive profiling
module modifies what a user sees or is alerted to based upon the user's
behavior, usage of a particular content source and navigation by the user
through the site.

CONTENT DELIVERY

    DYNAMIC FORMATTING.  The dynamic formatting module allows for active layout
of content for presentation to the user. Formatting can be based upon a specific
user's registration information, the type of content the user is viewing, the
CHOICE Web site and access point. The utilization of Extensible Style Language
(XSL) allows for quick and efficient formatting modifications. For example, XSL
converts or transforms information stored in XML into other data formats, such
as Hypertext Markup Language (HTML), used to construct most Web pages. This
module gives us the option of having multiple product offerings with different
features, while using the same content from the same repository.

COMPETITION

    The market for Internet services and products is relatively new, intensely
competitive and rapidly changing. With no substantial barriers to entry, over
15,000 Web sites presently offer users healthcare content and products and
services, and we expect that competition will continue to grow. We compete,
directly and indirectly, for subscribers, consumers, content and service
providers, advertisers, sponsors and acquisition candidates with a variety of
companies from traditional healthcare print publishers and distributors, to
health focused and general Web sites, to large healthcare information systems
companies.

    Many of our competitors enjoy significant competitive advantages including:
greater resources that can be devoted to the development, promotion and sale of
their products and services; longer operating histories; greater brand
recognition; and larger customer bases.

    We believe that the principal competitive factors in our target markets are
comprehensiveness of content, integration with existing technologies, brand name
recognition, performance, ease of use, pricing, features and quality of support.
We also believe that we are the only provider among our competitors to serve all
of our target markets and that the combination of the depth and breadth of our
content libraries and the flexibility of our technology platform allows us to
compete favorably in each of our target markets. See "Risk Factors--We face
intense competition in providing our Internet-based healthcare information
products and services and we may not be able to compete effectively."

    We syndicate portions of our content to other competing health related Web
sites, including WebMD and Inteli-health. We believe that the benefits of
content syndication, including additional traffic to the HealthGate Network,
increased awareness of the HealthGate brand and additional advertising and
sponsorship and e-commerce opportunities, outweigh the disadvantages of a
potential increase in competition that may result from our content syndication
to these competitors. See "Business--HealthGate's Products and Services--Content
Syndication."

GOVERNMENTAL REGULATION

    Currently, there are a number of laws that regulate communications or
commerce on the Internet. Federal, state, local and foreign governments and
agencies are considering laws and regulations that address issues such as user
privacy, pricing, online content regulation, taxation and the characteristics
and quality of online products and services. In addition, several
telecommunications carriers have petitioned the Federal Communications
Commission to regulate Internet service providers and online

                                       67
<PAGE>
service providers in a manner similar to long distance telephone carriers and to
impose access fees on these providers. Regulation of this type, if imposed,
could substantially increase the cost of communicating on the Internet.

    Internet user privacy has become an issue both in the United States and
abroad. The Federal Trade Commission and government agencies in some states and
countries have been investigating certain Internet companies regarding their use
of personal information. Any regulations imposed to protect the privacy of
Internet users may affect the way in which we currently collect and use personal
information.

    As is typical with most Web sites, our Web sites place "cookies" on a user's
hard drive without the user's knowledge or consent. This technology enables Web
site operators to target specific users with a particular advertisement and to
limit the frequency with which a user is shown a particular advertisement.
Certain currently available Internet browsers allow users to modify their
browser settings to remove cookies at any time or to prevent cookies from being
stored on their hard drives. If this technology is reduced or limited, the
Internet may become less attractive to advertisers and sponsors.

    It may take years to determine the extent to which existing laws related to
issues such as intellectual property ownership and infringement, libel,
obscenity and personal privacy are applicable to the Internet and for new laws
to be adopted. Any new laws or regulations relating to the Internet, or the
application or interpretation of existing laws, could slow the growth in the use
of the Internet, decrease demand for our Web sites or otherwise materially
adversely affect our business. See "Risk Factors--Government regulation of the
Internet may result in increased costs of using the Internet which could
adversely affect our business," "--Privacy-related regulation of the Internet
could adversely affect our business," "--Tax treatment of companies engaged in
Internet commerce may adversely affect the Internet industry and our company"
and "--We may be subject to liability for claims that the distribution of
medical information to consumers constitutes practicing medicine on the
Internet."

INTELLECTUAL PROPERTY

    We regard our intellectual property as important to our business, and we
rely upon trademark and copyright law, trade secret protection and
confidentiality and/or license agreements with our employees, customers,
strategic partners and others to protect our rights in this property. Effective
trademark, copyright and trade secret protection may not be available in every
country in which our products and media properties are distributed or made
available through the Internet. Therefore, we can not guarantee that the steps
we have taken to protect our proprietary rights will be adequate to prevent
infringement or misappropriation by third parties or will be adequate under the
laws of some foreign countries which may not protect our proprietary rights to
the same extent as do the laws of the United States.

    We license almost all of our content from third parties. Although under most
of our license agreements, the licensor has agreed to defend and indemnify us
for losses with respect to third-party claims that the licensed content
infringes third-party proprietary rights, we can not assure you that these
provisions will be adequate to protect us from infringement claims.


    We also rely on a variety of technologies that are licensed from third
parties, including our database and Internet server software, which is used for
our Web sites to perform key functions. These third-party licenses may not be
available to us on commercially reasonable terms in the future. The loss of or
inability to maintain any of these licenses could delay the introduction of
software enhancements, interactive tools and other features until equivalent
technology can be licensed or developed. See "Risk Factors--Our business may
suffer if we are not able to effectively protect our intellectual property
rights."

LEGAL PROCEEDINGS


    We are not currently a party to or aware of any material legal proceedings
involving us.



    We received a letter dated July 27, 1999 from TechSearch L.L.C. claiming
ownership of a patent that claims exclusive rights to all electronic methods of
on-demand remote retrieval of graphic and audiovisual information. The letter
asserted that the use of our Web site, www.healthgate.com, infringes the patent.
In the letter, TechSearch offered to license the patent perpetually and
retroactively to us for a one-time fee of between $50,000 and $150,000 depending
upon the number of "hits" per day on our web site. We are currently
investigating this matter. At this time, however, we are unable to predict its
outcome.

BOARD COMMITTEES

    AUDIT COMMITTEE.  The Audit Committee consists of Messrs. de Castro, Friend
and Horgen. The Audit Committee's primary responsibilities are to assist the
board of directors by making recommendations to the board regarding the
selection of independent auditors, reviewing the results and scope of the audit
and other services provided by our independent auditors, and reviewing our

    COMPENSATION COMMITTEE.  The Compensation Committee consists of Dr. Blair
and Messrs. Conibear and Horgen. The Compensation Committee makes
recommendations to the board concerning salaries and incentive compensation for
our employees and consultants, including all executive officers and the Chief
Executive Officer.

DIRECTOR COMPENSATION

    Directors of HealthGate who are also our employees will not receive
additional compensation for serving as directors. As compensation for their
services in 1996 through 1998, in December 1996, each of our non-employee
directors was granted stock options for the purchase of 29,745 shares of our
common stock under our 1994 Stock Option Plan. These options have an exercise
price of $1.16 per share, vested in three equal annual installments in 1996,
1997, and 1998 and expire in December 2001.

    As compensation for their services in 1999 through 2001, in January 1999,
each of our non-employee directors was granted stock options for the purchase of
9,915 shares of our common stock under our 1994 Stock Option Plan. These options
have an exercise price of $0.89 per share, vest in three equal annual
installments in January 1999, 2000 and 2001 based on continuing service as a
director through each applicable period and expire in January 2004.

                                       72

    In addition, Mr. de Castro was granted options to purchase an additional
9,915 shares of our common stock in November 1997 for consulting services he
rendered to us after the option grant date and prior to December 31, 1998. This
option had an exercise price of $0.49 per share, was fully vested during 1998
and was exercised by Mr. de Castro in October 1999.

    Our directors do not receive cash remuneration for their services as
directors. We currently reimburse our non-employee directors for the
out-of-pocket expenses they incur in connection with rendering services as
directors.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    None of our executive officers serves as a member of the board of directors
or compensation committee of any entity that has one or more of its executive
officers serving as a member of our board of directors or Compensation
Committee. Our Compensation Committee currently consists of Dr. Blair and
Messrs. Conibear and Horgen, none of whom has ever been an officer or employee
of HealthGate.

(1) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. These gains
    are based on assumed rates of stock price appreciation of 5% and 10%
    compounded annually from the date the respective options were granted to
    their expiration date. These assumptions are not intended to forecast future
    appreciation of our stock price. The potential realizable value computation
    does not take into account federal or state income tax consequences of
    option exercises or sales of appreciated stock. The actual gains, if any, on
    the stock option exercises will depend on the future performance of the
    common stock, the optionee's continued employment through applicable vesting
    periods and the date on which the options are exercised and the underlying
    shares are sold.

(2) In 1998, we granted options to employees to purchase an aggregate of 826,911
    shares of common stock.

(3) Includes a non-qualified option for 39,660 shares fully vested upon grant
    and an incentive stock option for 257,790 shares, 1/3 of which vested on
    January 23, 1999, 1/3 of which will vest on January 23, 2000, and the
    remaining 1/3 of which will vest on January 23, 2001, subject to

(1) There was no public trading market for the common stock on December 31,
    1998. Accordingly, for purposes of this table, the values in these columns
    have been calculated assuming an initial public offering price of $9.00 per

EMPLOYEE BENEFIT PLANS

    1994 STOCK OPTION PLAN.  Our 1994 Stock Option Plan was adopted by the board
of directors and approved by the stockholders in June 1994. The 1994 Stock
Option Plan provides for the grant of "incentive stock options" intended to
qualify under Section 422 of the Internal Revenue Code and stock options that do
not so qualify. The granting of incentive stock options is subject to the
limitations set forth in the 1994 Stock Option Plan. Our directors, officers,
employees and consultants are eligible to receive grants under the 1994 Stock
Option Plan. The purpose of the 1994 Stock Option Plan is to promote the
interests of HealthGate and our stockholders by encouraging and enabling
eligible employees and other persons affiliated with HealthGate to acquire stock
in HealthGate. We believe that the granting of options will stimulate the
efforts of these persons, strengthen their desire to remain with HealthGate,
provide them with more aligned interests in HealthGate's success and assure a
closer identification between them and HealthGate.


    The 1994 Stock Option Plan is administered by our board of directors, which,
subject to the limitations on incentive stock options discussed above, has
authority to determine the optionees, the number of shares covered by an option,
the option exercise price, the term of the option, the vesting schedule and
other terms and conditions. The 1994 Stock Option Plan provides for the grant of
options covering up to 3,599,997 shares of common stock. If an option expires,
terminates or is forfeited for any reason during the term of the 1994 Stock
Option Plan without having been exercised in full, the shares subject to the
unexercised portion of such option will again be available for grant pursuant to
the 1994 Stock Option Plan.



    As of November 19, 1999, options for a total of 2,469,495 shares of common
stock are outstanding under the 1994 Stock Option Plan. In addition, 97,871
shares of common stock have been purchased under the 1994 Stock Option Plan
pursuant to exercises of options. A total of 1,032,631 shares remain available
for issuance under the 1994 Stock Option Plan.


    401(K) PLAN.  We have established a tax-qualified employee savings and
retirement plan, or the 401(k) Plan, which covers all of our full-time employees
who have completed three months of service. Under the 401(k) Plan, eligible
employees may defer up to 15% of their pre-tax earnings, subject to the Internal
Revenue Service's annual contribution limit. The 401(k) Plan permits additional
discretionary matching contributions by us on behalf of all participants in the
401(k) Plan in such a percentage amount as may be determined annually by the
board of directors. To date, we have made no matching contributions. The 401(k)
Plan is intended to qualify under Section 401 of the Internal Revenue Code so

    We may terminate Mr. Reece's employment for malfeasance, nonfeasance or

directors. If we terminate Mr. Reece's employment for malfeasance, nonfeasance
or breach of the employment agreement, Mr. Reece will be entitled to receive a

                              CERTAIN TRANSACTIONS

    Pursuant to the terms of various leases, ranging in terms from at-will to
two years, in 1996, 1997 and 1998, we leased our main offices in Malden,
Massachusetts from Leonard School Associates, Inc., the owner of these offices
until December 1998. Pursuant to these leases, in 1996 we paid rent of
approximately $58,000, in 1997 we paid rent of approximately $84,000 and in 1998
we paid rent of approximately $89,000. Leonard School Associates is owned in
part by Barry M. Manuel, M.D. Dr. Manuel holds options to purchase 22,209 shares
of our common stock, and holds, for himself and through trusts for which he is
the trustee and has sole voting power, an aggregate of 1,189,800 shares of our
common stock. Dr. Manuel is also the father-in-law of William S. Reece, our
Chairman, President and Chief Executive Officer.

    In March 1998, we entered into an Electronic Journal Software Development
and Management Agreement with Blackwell Science. Blackwell Science is the
holder, together with Blackwell Wissenshafts-Verlag GmbH, a wholly-owned
subsidiary of Blackwell Science, of all of our issued and outstanding Series D
Convertible Preferred Stock, and Jonathan Conibear, one of our directors, is an
Executive Director of Blackwell Science. Pursuant to this agreement, we have
agreed to develop and host a Web site for Blackwell Science's journals and other
publications. We completed the development of this Web site in 1998. Blackwell
Science has paid a total of $1,400,000 for the development and hosting of the
Web site through December 1999. During 1998 and 1997, our revenue from Blackwell
Science represented 44% and 18% of our total revenue for those respective years.
In September 1999 we entered into a new activePress Journal Hosting and Delivery
Agreement with Blackwell Science pursuant to which the term of our services
relating to hosting and maintaining Blackwell Science's Web site was extended
through December 2001 and the scope of our services to be provided to Blackwell
Science will be expanded beginning January 1, 2000. Total fees payable to us
during the extended term are expected to be in excess of $800,000 annually. In
April 1999, we paid Blackwell Science $68,000 as a referral fee for their
assistance in adding several additional journals to our online libraries. In
addition, pursuant to the terms of a Stock Purchase Agreement dated as of
December 20, 1996 between HealthGate and Blackwell Science, in the event we
attempt to expand into Europe or Asia, we have agreed to negotiate in good faith
with Blackwell Science to determine in what manner Blackwell Science may serve
as our primary strategic alliance partner in connection with such expansion.

    In May 1998, we purchased certain of the assets, principally computer
hardware and software and office furnishings, of Systems Architects, Inc. for
$70,000 in cash. Systems Architects, Inc. was a company owned by Hamid
Tabatabaie, our former Vice President of Sales and Marketing.

    In September 1998, we received a $2,000,000 convertible bridge loan from
Blackwell Science. The loan accrued interest at a rate of 12% per year. The
principal amount of this loan was converted into 174,729 Series E preferred
stock in April 1999 concurrently with, and at the same per share price as, the
private placement of Series E preferred stock to GE Capital Equity Investments,
Inc. Upon conversion, all accrued and unpaid interest due on this loan was paid
to Blackwell Science in cash.

    In connection with the sale of Series B preferred stock to Nichols Research
Corporation in 1996, we agreed to use certain consulting services of Nichols
Research. In 1996, we paid Nichols Research approximately $203,000 for these
consulting services. Additionally in 1996, we paid Nichols Research
approximately $90,900 under a capital lease arrangement for computer equipment.
Nichols Research is one of our stockholders and Chris Horgen, one of our
directors, is Chairman of the Board of Directors of Nichols Research.

    In April 1999, pursuant to the terms of a Stock Purchase Agreement, we
issued and sold 546,028 shares of our Series E preferred stock to GE Capital
Equity Investments for an aggregate consideration of $6,250,000 in cash.


    In June 1999, we entered into a development and distribution agreement with
GE Medical Systems pursuant to which we will develop GE Medical Systems branded
enhanced versions of our CHOICE


                                       77
<PAGE>

Web site product. In connection with this agreement, we issued to General
Electric Company a warrant for the purchase of up to 1,189,800 shares of our
common stock. The warrant has a term of five years, an exercise price of $9.49
per share (subject to potential adjustments for certain equity offerings
subsequent to the warrant's issuance and other events) and is immediately
exercisable. See "Business--Strategic Affiliations and Relationships--Marketing
and Distribution." GE Capital Equity Investments, Inc., a stockholder of
HealthGate is an affiliate of General Electric Company.



    In October 1999, we entered into a three-year strategic alliance agreement
with Snap! LLC and Xoom.com, Inc. Under this agreement, Snap will provide
various services to us to promote our name, our www.healthgate.com Web site, our
co-branded CHOICE Web sites and the products and services we offer, and we will
design, develop and host a co-branded Snap/HealthGate Web site, which will
provide the features and functionality of our www.healthgate.com Web site. After
the co-branded Snap/ HealthGate Web site is brought online, which is scheduled
to occur following this offering, Snap will feature us as the anchor tenant,
giving us the exclusive right to be the most prominent content provider, for
seven of the major content areas within the Health Channel, which is part of
Snap's Web site located at www.snap.com. In exchange for the services provided
to us by Snap during the first year of the agreement, we have agreed to pay Snap
a minimum fee of $10.0 million and 500,000 shares of our common stock, plus a
$250,000 production and content integration fee. We have agreed to pay Snap
minimum fees of $15.0 million in each of the second and third years of the
agreement for the services provided to us by Snap in those years. We have also
agreed to pay Snap up to an additional $5.0 million in the first year,
$10.0 million in the second year and $15.0 million in the third year of the
agreement if Snap delivers more than certain minimum click-throughs to the
co-branded Snap/ HealthGate Web site. The minimum click-through threshold is
8,333,000 for year one, 9,375,000 for year two and 10,714,000 for year three.
NBC, a subsidiary of General Electric, owns a majority interest in Snap.


    In November 1999, we entered into a three-year development agreement with
Columbia Information Systems. Under this agreement, we will design, develop and
maintain a health portal site for Columbia Information Systems and design,
develop and maintain customized, co-branded CHOICE Web sites for up to 280
Columbia/HCA hospitals and affiliates. The agreement provides for an annual
license fee of $3.5 million to be paid by Columbia Information Systems for all
products and services that we provide under the agreement. The annual license
fee is subject to prospective adjustment in certain events, including the
delivery by us of fewer than 200 or more than 280 customized, co-branded CHOICE
Web sites. However, if we deliver fewer than 200 customized, co-branded CHOICE
Web sites, the adjustment is limited to a minimum annual license fee of $2.5
million. In addition, we will share advertising and sponsorship revenues and
certain e-commerce revenues. The agreement may be terminated without cause by
Columbia Information Systems on June 1, 2001, upon payment of a $1 million
termination fee to HealthGate.


    In November 1999, we also entered into a separate three-year marketing and
reseller agreement with Columbia Information Systems, under which Columbia
Information Systems agreed to endorse us as the preferred provider of patient
and consumer oriented health content for Web sites owned or operated by
Columbia/HCA hospitals and affiliates. The agreement provides us, among other
things, the right to make a first offer to provide services for adding content
to the Columbia Information Systems health portal site and any Web sites owned
or operated by or affiliated with Columbia Information Systems or Columbia/HCA.
We also have the exclusive right to host on the Internet content provided to us
by healthcare providers owned, controlled or operated by any entity owned or
controlled by Columbia/HCA Healthcare Corporation. In addition, Columbia
Information Systems may, for a commission, market and sell our CHOICE Web site
product to entities unaffiliated with Columbia/HCA, subject to our approval. In
connection with this agreement, we have issued to CIS Holdings, Inc., an
indirect, wholly-owned subsidiary of Columbia/HCA HealthCare Corporation and an
affiliate of Columbia Information Systems, a warrant for the purchase of up to
1,941,035 shares of our common stock. The warrant has a term of three years, an
exercise price per share equal to the initial public offering price (subject to
adjustment in certain circumstances) and is exercisable on the earlier to occur
of this offering, certain private placements of securities, a sale of HealthGate
or March 31, 2000.

    Our amended and restated charter and our amended and restated bylaws will
each become effective upon the closing of this offering. Upon the effectiveness
of the amended and restated charter, our authorized capital stock will consist
of 100,000,000 shares of common stock, $.01 par value per share, and 10,000,000
shares of preferred stock, $.01 par value per share.

    The description set forth below gives effect to the filing of the amended
and restated charter and the adoption of the amended and restated bylaws. The
following summary is qualified in its entirety by reference to our amended and
restated charter and bylaws, copies of which are filed as exhibits to the
registration statement of which this prospectus is a part.

COMMON STOCK

    Holders of common stock are entitled to one vote per share for each share
held of record on all matters submitted to a vote of stockholders. Holders of
common stock do not have cumulative voting rights, and therefore the holders of
a majority of the shares of common stock voting for the election of directors
may elect all of our directors standing for election. Subject to preferences
that may be applicable to the holders of outstanding shares of preferred stock,
if any, the holders of common stock are entitled to receive dividends as may be
declared by the board of directors. In the event of a liquidation, dissolution
or winding up of our affairs, whether voluntary or involuntary, and subject to
the rights of the holders of outstanding shares of preferred stock, if any, the
holders of shares of common stock shall be entitled to receive, on a pro rata
basis, all of our remaining assets available for distribution to our
stockholders. The holders of common stock have no preemptive, redemption,
conversion or subscription rights. All outstanding shares of common stock are,
and the shares of common stock to be issued pursuant to this offering will be,
fully paid and non-assessable.

                                       81
<PAGE>
PREFERRED STOCK

    The board is authorized to issue, subject to any limitations prescribed by
Delaware law, preferred stock in one or more series. At the time of issuance,
and without further vote or action by the stockholders, the board can:

    - establish the number of shares to be included in each series;

    - fix the powers, designations, preferences and relative participating,
      optional or other special rights, and the qualifications, limitations or
      restrictions thereof, of the shares of each series; and

    - increase or decrease the number of shares of any series, subject to the
      existing number of authorized shares of preferred stock.

    The board is authorized to issue preferred stock with voting, conversion and
other rights and preferences that could adversely affect the voting power or
other rights of the holders of common stock. Therefore, although we have no
current plans to issue shares of preferred stock, the issuance of preferred
stock or of rights to purchase preferred stock could have the effect of making
it more difficult for a third party to acquire, or of discouraging a third party
from attempting to acquire, a majority of the outstanding voting stock of
HealthGate.

WARRANTS

    HealthGate has issued warrants to purchase an aggregate of 477,546 shares of
common stock, subject to certain antidilution adjustments. Warrants to purchase
455,892 shares have an exercise price of $0.00005 per share, may be exercised at
any time and expire in March 2008. Warrants to purchase 21,654 shares have an
exercise price of $2.89 per share, may be exercised at any time after April 20,
2000 and expire on April 21, 2002. Holders of warrants to purchase 455,892
shares of common stock are entitled to registration rights covering the shares
of common stock issuable upon exercise of these warrants. See "Shares Eligible
for Future Sale--Registration Rights."

    Additionally, in connection with a development and distribution agreement
with GE Medical Systems, on June 17, 1999, HealthGate issued to General Electric
Company a warrant for the purchase of up to 1,189,800 shares of common stock
with an exercise price of $9.49 per share (subject to potential adjustments for
certain equity offerings subsequent to the warrant's issuance and other events)
and is immediately exercisable. General Electric will also have registration
rights covering the shares of common stock issuable under the warrant.


    In connection with our marketing and reseller agreement with Columbia
Information Systems, we issued to CIS Holdings, Inc. a warrant for the purchase
of up to 1,941,035 shares of common stock with an exercise price per share equal
to our initial public offering price (subject to adjustment in certain
circumstances). The warrant will be exercisable on the earlier to occur of the
consummation of this offering, certain private placements of securities, a sale
of HealthGate or March 31, 2000. CIS Holdings will also have registration rights
covering the shares of common stock issuable under the warrant. See
"Business--Strategic Affiliations and Relationships--Marketing and Distribution"

    The amended and restated charter and the amended and restated bylaws contain
certain provisions that could discourage potential takeover attempts and make
more difficult attempts by stockholders to change HealthGate's management. The
amended and restated charter authorizes the board to issue, without stockholder
approval, shares of preferred stock in one or more series and to fix the voting
powers, preferences and rights and the qualifications, limitations and
restrictions of those shares. Although we have no current plans to issue
preferred stock, the issuance of preferred stock or of rights

                                       82
<PAGE>
to purchase preferred stock could make it more difficult for a third party to
acquire, or discourage a third party from attempting to acquire, a majority of
our outstanding voting stock.

    The amended and restated charter also provides for the division of the board
of directors into three classes as nearly equal in size as possible with
staggered three-year terms and for removal of directors only for cause. The
classification of the board of directors and the limitation on removal of
directors only for cause could make it more difficult for a third party to
acquire, or discourage a third party from attempting to acquire, control of
HealthGate. The amended and restated charter further provides that stockholders
may act only at stockholders' meetings and not by written consent in lieu of a
stockholders' meeting. The amended and restated bylaws provide that nominations
for directors may not be made by stockholders at any annual or special meeting
unless the stockholder intending to make a nomination notifies HealthGate of its
intentions a specified number of days, generally 60, in advance of the meeting
and furnishes to HealthGate certain information regarding itself and the
intended nominee. These provisions could delay any stockholder actions that are
favored by the holders of a majority of our outstanding stock until the next
stockholders' meeting. These provisions may also discourage another person or
entity from making a tender offer for HealthGate's common stock, because that
person or entity, even if it acquired a majority of the outstanding common stock
could only take action at a duly called stockholders' meeting and not by written
consent. The amended and restated bylaws also provide that special meetings of
stockholders may be called only by the Chief Executive Officer or a majority of
the directors. In addition, a stockholder wishing to bring business before any
annual or special meeting of stockholders must give advance notice to the
corporation, generally 60 days prior to the meeting, describing the proposal and
providing information regarding all stockholders known to be supporting the
proposal, including any material interest the supporting stockholders may have
in the proposal.

LIMITATION OF LIABILITY

    The amended and restated charter provides that no director will be
personally liable to HealthGate or to any stockholder for monetary damages
arising out of such director's breach of fiduciary duty, except to the extent
that the elimination or limitation of liability is not permitted by the Delaware
General Corporation Law. The Delaware General Corporation Law, as currently in
effect, permits charter provisions eliminating the liability of directors for
breach of fiduciary duty, except that directors remain liable for:

    (1) any breach of the director's duty of loyalty to a company or its
       stockholders;

    (2) any acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

    (3) any payment of a dividend or approval of a stock purchase that is
       illegal under Section 174 of the Delaware General Corporation Law; or

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

    A principal effect of this provision of the amended and restated charter is
to limit or eliminate the potential liability of our directors for monetary
damages arising from breaches of their duty of care, unless the breach involves
one of the four exceptions described in (1) through (4) above. The provision
does not prevent stockholders from obtaining injunctive or other equitable
relief against directors, nor does it shield directors from liability under
federal or state securities laws.

    The amended and restated charter and the amended and restated bylaws further
provide for the indemnification of directors and officers to the fullest extent
permitted by Section 145 of the Delaware General Corporation Law, including
circumstances in which indemnification is otherwise discretionary. HealthGate
has entered into indemnification agreements with each of its directors and
officers, pursuant to which HealthGate has agreed to indemnify such directors to
the fullest extent permitted by law for amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position.

    The transfer agent and registrar for the common stock is American Stock

                        SHARES ELIGIBLE FOR FUTURE SALE

    Upon completion of this offering, we will have 16,445,472 shares of common
stock outstanding, including 7,530,556 shares of common stock issuable upon
conversion of our outstanding preferred stock (assuming no exercise of the
underwriters' over-allotment option and no exercise of outstanding options and
warrants). Of these shares, the 3,750,000 shares we are offering will be freely
tradable in the public market without restriction or further registration under
the Securities Act of 1933. However, any shares purchased by our "affiliates,"
as that term is defined in Rule 144 under the Securities Act, may generally only
be sold in compliance with the limitations of Rule 144 described below. The
remaining 12,695,472 shares of common stock outstanding upon completion of this
offering will be "restricted securities" as that term is defined in Rule 144
under the Securities Act. Restricted securities may not be sold except in
compliance with the registration requirements of the Securities Act or an
applicable exemption under the Securities Act, including an exemption pursuant
to Rule 144.

SALES OF RESTRICTED SECURITIES

    Upon completion of this offering, 281,936 of the restricted securities will
become eligible for sale in the public market pursuant to Rule 144. Upon the
expiration of the lock-up agreements entered into by us, our executive officers
and directors and all principal stockholders and most of our other stockholders
in connection with this offering, 9,978,141 of the restricted securities may be
sold pursuant to Rules 144 or 701, subject in some cases to the volume and other
limitations imposed by those rules. The remaining 2,435,395 shares will be
eligible for sale upon the expiration of a one-year holding period, subject to
the restrictions and conditions of Rule 144.

    In general, under Rule 144 as currently in effect, a person, including any
affiliate of HealthGate who has beneficially owned shares for at least one year,
will be entitled to sell in "brokers' transactions" or directly to market makers
within any three-month period commencing 90 days after the date of this
prospectus, a number of restricted securities that does not exceed the greater
of (1) 1% of the class of such shares then outstanding (approximately 164,455
shares immediately after this offering); or (2) the average weekly trading
volume of the common stock during the four calendar weeks immediately preceding
the sale. In addition, a person who is not an affiliate of HealthGate at any
time during the three months preceding any sale by such person, and who has
beneficially owned the shares proposed to be sold for at least two years, is
entitled to sell such shares under Rule 144(k) without regard to the limitations
described above.

    In addition, existing holders with an aggregate of 8,255,626 shares of
common stock have the right to require registration of their shares under
certain circumstances. However, holders of 8,076,976 shares of this common stock
have entered into lock-up agreements with respect to these shares, which provide
that they will not sell or otherwise dispose of any shares of common stock
without the prior written consent of SG Cowen Securities Corporation for a
period of 180 days from the date of this prospectus. SG Cowen Securities
Corporation may, in its sole discretion and at any time without notice, release
all or any portion of the securities subject to lock-up agreements. See
"Registration Rights" and "Underwriting."

    As of November 19, 1999, options to purchase an aggregate of 1,003,893
shares of common stock were fully vested. Holders of fully vested options to

their shares under certain circumstances. Of the total shares issuable pursuant
to vested options, 858,477 are subject to 180-day lock-up agreements. As of

director of, or consultant or advisor to HealthGate who purchases shares from
HealthGate pursuant to a written compensatory stock option or other benefit plan
or written contract relating to compensation is eligible to resell such shares,
in each case commencing 90 days after the date of this prospectus, in reliance
on Rule 144, but without compliance with certain restrictions contained in
Rule 144. Shares acquired pursuant to Rule 701 may be sold by nonaffiliates
without regard to the holding period, volume limitations, information or notice
requirements of Rule 144, and by affiliates without regard to the holding period
requirement.

    We intend to file one or more registration statements on Form S-8 under the
Securities Act to register all shares of common stock subject to outstanding
stock options and common stock issuable pursuant to our 1994 Stock Option Plan.
We expect to file these registration statements following the expiration of the

statements will be eligible for sale in the public markets.

have also entered into a registration agreement with CIS Holdings granting
registration rights with respect to 1,941,035 shares of common stock issuable
upon exercise of a warrant. See "Business--Strategic Affiliations and
Relationships--Marketing and Distribution." The registration rights relating to
the securities issuable upon exercise of this warrant are substantially similar
to the registration rights of the Registrable Securities described below. In
addition, we have granted piggy-back registration rights, which are subject to
the limitations on priority of registration permitted under all of our other
existing registration agreements, with respect to 500,000 shares of common stock
held by Snap.


    DEMAND REGISTRATION RIGHTS.  Subject to certain limitations in the
registration agreements, the holders of at least 40% of the Registrable
Securities may require, on two occasions at any time after six months from the
closing of this offering, that we use our best efforts to register all or part
of the Registrable Securities on Form S-1 or any similar long-form registration
statement. In addition, subject to certain limitations in the registration
agreements, the holders of at least 25% of the Registrable Securities may also
require, on four occasions at any time six months from the closing of this
offering, that we use our best efforts to register all or a portion of the

statement when use of one or more of these forms becomes available to us.

    Subject to certain limitations in the registration agreement between us and
GE Capital Equity Investments, Blackwell Science and a Blackwell affiliate, the
holders of the GE-Blackwell Securities may require, on two occasions at any time
six months from the closing of this offering, that we use our best efforts to
register all or part of the GE-Blackwell Securities for public resale on
Form S-1 or any similar long-form registration, provided that the aggregate
offering value of each such long-form registration includes the lesser of:

    - at least 30% of the common stock issuable upon conversion of the initial
      87,364 shares of Series E Stock issued to GE Capital Equity Investments,
      and

      anticipated offering price of at least $5 million. In addition, subject to
      limitations in the registration agreements currently, the holders of the
      GE-Blackwell Securities may also require, on four occasions at any time
      six months from the closing of this offering, that we use our best efforts

    PIGGYBACK REGISTRATION RIGHTS.  If we register any of our common stock,
either for our own account or for the account of other security holders, and the
registration form to be used may be used for the registration of the Registrable

Securities and the GE-Blackwell Securities are entitled to include their shares
of common stock in the

                                       86

registration. A majority of the holders of Registrable Securities and
GE-Blackwell Securities have waived their rights to register securities in
connection with this offering.

    In all cases, a holder's right to include shares in a demand or piggyback
registration is subject:

    - to the registration priority arrangement reached among HealthGate and the
      holders of the Registrable Securities or GE-Blackwell Securities; and

    - in an underwritten registration, to the ability of the underwriters to
      limit the number of shares included in the offering.

    All fees, costs and expenses of all of the registrations will be paid by us,
and all selling expenses (e.g. underwriting discounts, selling commissions and
stock transfer taxes) relating to the Registrable Securities or GE-Blackwell
Securities will be paid by the holders of the securities being registered.

underwriting agreement with respect to the shares being offered. Subject to
certain conditions, each underwriter has severally agreed to purchase the number

prospectus. SG Cowen Securities Corporation, Volpe Brown Whelan & Company, LLC
and Warburg Dillon Read LLC are the representatives of the underwriters.

    The underwriting agreement provides that the obligations of the underwriters
are conditional and may be terminated at their discretion based on their
assessment of the state of the financial markets. The obligations of the
underwriters may also be terminated upon the occurrence of the other events
specified in the underwriting agreement. The underwriters are severally
committed to purchase all of the common stock being offered by us if any shares
are purchased, other than those covered by the over-allotment option described
below.

    The underwriters, at the request of HealthGate, have reserved for sale to
HealthGate employees, friends and family members of employees and to employees
of companies with which HealthGate does business, at the initial public offering
price, up to five percent of the shares of common stock to be sold in this
offering. The number of shares available for sale to the general public will be
reduced to the extent that any reserved shares are purchased.


    At the request of HealthGate, the underwriters will reserve up to
$5.0 million of common stock at the initial public offering price for sale to
Snap! LLC. National Broadcasting Company, Inc., a subsidiary of General Electric
Company, owns a majority interest in Snap. This amount would represent an
aggregate of 500,000 shares, based on an assumed initial public offering price
of $10.00 per share, the mid-point of the price range indicated on the cover of
this prospectus. The number of shares reserved for sale to Snap! LLC will reduce
the number of shares available to the general public. We cannot assure you that
any of these reserved shares will be purchased by Snap. Snap will agree that, if
it purchases any shares of common stock of HealthGate, it will not sell or
otherwise dispose of such shares for a period of 180 days following the date of
this prospectus. Any reserved shares not so purchased by Snap will be offered by
the underwriters to the general public on the same basis as the other shares
offered hereby.


    The underwriters propose to offer the common stock directly to the public at
the public offering price set forth on the cover page of this prospectus. The
underwriters may offer the common stock to securities dealers at that price less
a concession not in excess of $   per share. Securities dealers may reallow a
concession not in excess of $   per share to other dealers. After the shares of
the common stock are released for sale to the public, the underwriters may vary
the offering price and other selling terms from time to time.

    We have granted to the underwriters an option to purchase up to 562,500
additional shares of common stock at the public offering price set forth on the
cover of this prospectus to cover over-allotments, if any. The option is
exercisable for a period of 30 days. If the underwriters exercise their
over-allotment option, the underwriters have severally agreed to purchase shares
in approximately the same proportion as shown in the table above.

    We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act, and to contribute to payments
that the underwriters may be required to make in respect of those liabilities.


    HealthGate, our directors and executive officers, all principal stockholders
and other existing stockholders who hold an aggregate of 12,413,536 shares,
together with the holders of options to purchase 1,612,118 shares of common
stock and holders of warrants to purchase 3,586,727 shares of common stock, have
agreed with the underwriters that for a period of 180 days following the date of
this prospectus, without the prior written consent of SG Cowen Securities
Corporation, they will not dispose of or hedge any shares of common stock or any
securities convertible into or exchangeable for common stock.


    The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions, penalty bids and passive market making in
accordance with Regulation M under the Securities Exchange Act of 1934.
Over-allotment involves syndicate sales in excess of the offering size, which
creates a syndicate short position. Stabilizing transactions permit bids to
purchase the underlying security so long as the stabilizing bids do not exceed a
specified maximum. Syndicate covering transactions involve purchases of the
common stock in the open market after the distribution has been completed in
order to cover syndicate short positions. Penalty bids permit the
representatives to reclaim a selling concession from a syndicate member when the
common stock originally sold by such syndicate member is purchased in a
syndicate covering transaction to cover syndicate short positions. In passive
market making, market makers in the common stock who are underwriters or
prospective underwriters may, subject to certain limitations, make bids for or
purchases of the common stock until the time, if any, at which a stabilizing bid
is made. These stabilizing transactions, syndicate covering transactions and
penalty bids may cause the price of the common stock to be higher than it would
otherwise be in the absence of these transactions. These transactions may be
effected on the Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

    The underwriters have advised us that they do not intend to confirm sales in
excess of 5% of the common stock offered hereby to any account over which they
exercise discretionary authority.

    Prior to this offering, there has been no public market for the common
stock. Consequently, the initial public offering price was determined by
negotiations between us and the underwriters. Among the factors considered in
these negotiations were prevailing market conditions, the market capitalizations
and the stages of development of other companies that we and the underwriters
believe to be comparable to us, estimates of our business potential, our results
of operation in recent periods, the present state of our development and other
factors deemed relevant.

    We estimate that our out of pocket expenses for this offering, not including
the underwriting discount, will be approximately $2,387,500.

Shearman & Sterling, New York, New York.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of HealthGate Data Corp.


The common stock split described in Note 1 to the financial statements has not
been consummated at November 23, 1999. When it has been consummated, we will be
in a position to furnish the following report:



"In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of changes in common stock and other
stockholders' deficit and of cash flows present fairly, in all material
respects, the financial position of HealthGate Data Corp. and its subsidiary at
December 31, 1997 and 1998, and the results of their operations and their cash
flows for each of the three years in the period 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
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.


The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has incurred losses and negative cash flows
from operations since inception, which raise substantial doubt about the
Company's ability to continue as a going concern. Management's plans in regard
to these matters are also described in Note 1. The financial statements do not
include any adjustments that might result from the outcome of this uncertainty."

SUPPLEMENTAL DISCLOSURE OF CASH FLOW INFORMATION
HealthGate paid cash for interest of approximately $24,000, $28,000 and $242,000
for the years ended December 31, 1996, 1997 and 1998, respectively, and $152,000
(unaudited) and $439,000 (unaudited) for the nine months ended September 30,
1998 and 1999, respectively.



SUPPLEMENTAL DISCLOSURE OF NON-CASH FINANCING ACTIVITIES
HealthGate entered into capital leases for certain computer equipment totaling
approximately $87,000, $71,000 and $577,000 during the years ended December 31,
1996, 1997 and 1998, respectively, and $503,000 (unaudited) and $523,000
(unaudited) during the nine months ended September 30, 1998 and 1999,
respectively.


In connection with the issuance of the Series E redeemable convertible preferred
stock in April 1999, HealthGate issued a placement agent a warrant to purchase
up to 21,654 shares of HealthGate common stock at an exercise price of $2.89 per
share. A value of $200,000 was ascribed to the warrant. Also in April 1999, a
$2,000,000 convertible note payable to a related party was converted into
174,729 shares of HealthGate's Series E redeemable convertible preferred stock
(Note 3).

In June 1999, HealthGate issued a warrant to a related party in connection with
a development and distribution agreement. The fair value of the warrant of
$10,300,000 was recorded as marketing and distribution rights, and will be
amortized as a sales and marketing expense on a straight-line basis over the one
year contractual term of the related development and distribution agreement.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    HealthGate Data Corp. ("HealthGate") is an Internet provider of healthcare
information designed to help physicians and other healthcare professionals,
patients and health-conscious consumers make better-informed healthcare
decisions. HealthGate was incorporated in the State of Delaware on February 8,
1994.

    HealthGate is subject to risks and uncertainties common to growing
technology-based companies, including rapid technological developments, reliance
on continued development and acceptance of the Internet, intense competition and
a limited operating history.

    The Company intends to declare a 3.966 for 1 stock split, subject to
shareholder approval. All share and per share amounts presented have been
restated to reflect the stock split.

    HealthGate has sustained losses and negative cash flows from its operations
since inception. These matters raise substantial doubt about HealthGate's
ability to continue as a going concern for at least the next twelve months.
Management currently intends to raise financing through a firm commitment
underwritten initial public offering, the proceeds of which are expected to
exceed cash requirements for the next twelve months. If the initial public
offering is not successfully completed, management intends to obtain alternative
financing through the private placement of debt or equity, and reduce
expenditures so as to minimize requirements for additional financial resources.
Management believes that, if this offering is not completed, HealthGate will be
able to successfully execute its alternative plans. The financial statements do
not include any adjustments that might result from the outcome of this
uncertainty.

    Significant accounting polices followed in the preparation of the financial
statements are as follows:

PRINCIPLES OF CONSOLIDATION

    The consolidated financial statements include the accounts of HealthGate and
its wholly-owned subsidiary, HealthGate Europe Limited. All material
intercompany balances and transactions have been eliminated.

TRANSLATION OF FOREIGN CURRENCIES

    The functional currency of HealthGate's foreign subsidiary is the local
currency. Adjustments resulting from the translation of the financial statements
of HealthGate's subsidiary into U.S. dollars, and foreign currency transaction
gains and losses included in the results of operations, have not been
significant.

CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES

    HealthGate considers all highly liquid debt instruments purchased with an
original maturity of three months or less to be cash equivalents. HealthGate
invests its excess cash in money market funds backed by U.S. Government
securities, U.S. Treasury securities and commercial paper which are subject to
minimal credit and market risk. HealthGate's cash equivalents are classified as
available for sale and recorded at amortized cost, which approximates fair
value. HealthGate's marketable securities are classified as held-to-maturity and
recorded at amortized cost, which approximates fair value.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION

    HealthGate derives revenue primarily from user subscriptions and transaction
based fees, Web site development and hosting arrangements, content syndication
arrangements and the sale of advertising and sponsorships under short-term
contracts. Revenue from user subscriptions is recognized ratably over the
subscription period, and revenue from usage fees is recognized when the service
is provided. Revenue from Web site development and hosting arrangements and
content syndication arrangements is recognized ratably over the terms of the
underlying agreements between HealthGate, the customer and, if applicable,
HealthGate's authorized reseller, which generally range from one to three years.
For any arrangement in which HealthGate guarantees advertising commissions to
the customer, HealthGate records fees paid by the customer as a customer
deposit, up to the amount of the applicable guarantee. Payments made to
customers under these guarantees are recorded as reductions of the related
customer deposit. The excess of the fee paid by the customer to HealthGate over
guaranteed advertising and sponsorship commissions, if any, is recognized as
revenue ratably over the term of the underlying agreement. For those
arrangements in which HealthGate guarantees advertising and sponsorship
commissions in excess of the fees paid by the customer, the excess is recorded
as expense upon signing the agreement. For arrangements in which HealthGate
sells through a reseller, HealthGate does not recognize any revenue until an
agreement has been finalized between HealthGate, its customer and its authorized
reseller and Web site has been delivered.

    Advertising revenue is derived principally from short-term advertising
contracts, in which HealthGate typically guarantees a minimum number of
impressions to be delivered to users over a specified period of time for a fixed
fee. Advertising revenue is recognized in the period in which the advertisement
is displayed, at the lesser of the ratio of impressions delivered over total
guaranteed impressions or a straight line basis over the term of the contract,
provided that no significant HealthGate obligations remain. To the extent that
minimum guaranteed impressions are not met, HealthGate defers recognition of the
corresponding revenue until the guaranteed impressions are delivered.
Sponsorship revenue is recognized ratably over the terms of the applicable
agreements, which generally range from one to six months.


    Advertising and sponsorship revenue also includes barter revenue, which
represents an exchange by HealthGate of advertising space on HealthGate's Web
sites for reciprocal advertising space on other Web sites. Revenue from
advertising barter transactions is recognized during the period in which the
advertisements are displayed by HealthGate. Barter transactions are recorded at
the estimated fair value of the advertisements provided, unless the fair value
of the advertisments received is more evident. Barter expenses are recognized
when HealthGate's advertisements are run on the reciprocal Web sites, which is
typically in the same period as when the advertisements are run on HealthGate's
Web sites. Barter expenses are included in sales and marketing expenses. During
the years ended December 31, 1996, 1997 and 1998, revenue from barter
transactions was $125,000, $607,196 and $435,889, respectively. During the nine
months ended September 30, 1998 and 1999, revenue from barter transactions was
$350,192 and $72,538, respectively.


    Revenue from a research arrangement was recognized pursuant to the agreement
as the related work was performed. During the year ended December 31, 1996,
total revenue recognized and costs incurred under this arrangement were $87,171
and $81,442, respectively.

1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
FAIR VALUE OF FINANCIAL INSTRUMENTS


    The carrying amounts of HealthGate's financial instruments, which include
cash equivalents, accounts receivable, accounts payable, accrued expenses and
notes payable, approximate their fair values at December 31, 1997 and 1998.


CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS


    Financial instruments which potentially expose HealthGate to concentrations
of credit risk consist primarily of trade accounts receivable. To minimize risk,
ongoing credit evaluations of customers' financial condition are performed,
although collateral generally is not required. At December 31, 1997, one
customer accounted for 63% of gross accounts receivable. At December 31, 1998,
two customers accounted for 20% and 11% of gross accounts receivable, and a
related party accounted for 42% of gross accounts receivable. At September 30,
1999, one customer accounted for 37% of gross accounts receivable. For the year
ended December 31, 1996, two customers accounted for 15% and 11% of total
revenue, and revenue from a research arrangement accounted for 21% of total
revenue. For the year ended December 31, 1997, one customer accounted for 19% of
total revenue, and a related party accounted for 18% of total revenue. For the
year ended December 31, 1998, one customer accounted for 18% of total revenue
and a related party accounted for 44% of total revenue. For the nine months
ended September 30, 1998, one customer accounted for 18% of total revenue and a
related party accounted for 44% of total revenue. For the nine months ended
September 30, 1999, one customer accounted for 12% of total revenue and a
related party accounted for 33% of total revenue.


RESEARCH AND DEVELOPMENT AND SOFTWARE DEVELOPMENT COSTS

    Costs incurred in the research and development of HealthGate's products are
expensed as incurred, except for certain software development costs. Costs
associated with the development of computer software are expensed prior to the
establishment of technological feasibility (as defined by Statement of Financial
Accounting Standards ("SFAS") No. 86, "Accounting for the Costs of Computer
Software to be Sold, Leased or Otherwise Marketed") and capitalized thereafter
if material to HealthGate's financial position or results of operations. Costs
eligible for capitalization have been insignificant to date and, accordingly, no
amounts have been capitalized.

FIXED ASSETS

    Fixed assets are recorded at cost and depreciated over their estimated
useful lives, generally one to three years, using the straight-line method.
Fixed assets held under capital leases which involve a transfer of ownership are
amortized over the estimated useful life of the asset. Other fixed assets held
under capital leases are amortized over the shorter of the lease term or the
estimated useful life of the related asset. Repairs and maintenance costs are
expensed as incurred.

ACCOUNTING FOR STOCK-BASED COMPENSATION

    HealthGate accounts for stock-based awards to employees using the intrinsic
value method as prescribed by Accounting Principles Board ("APB") Opinion No.
25, "Accounting for Stock Issued to Employees," and related interpretations.
Accordingly, no compensation expense is recorded for options issued to employees
in fixed amounts and with fixed exercise prices at least equal to the fair
market

value of HealthGate's common stock at the date of grant. HealthGate has adopted
the provisions of SFAS No. 123, "Accounting for Stock-Based Compensation," for
disclosure purposes only (Note 5). All stock-based awards to non-employees are
accounted for at their fair value in accordance with SFAS No. 123 and related
interpretations.

ADVERTISING COSTS


    Advertising costs are charged to operations as incurred. Advertising costs
were approximately $410,000, $790,000, $456,000, $370,000, and $223,000 in the
years ended December 31, 1996, 1997 and 1998 and nine months ended
September 30, 1998 and 1999, respectively, of which approximately $115,000,
$617,000, $418,000, $332,000 and $73,000, respectively, related to barter
transactions.


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 the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

UNAUDITED PRO FORMA BALANCE SHEET


    The unaudited pro forma balance sheet at September 30, 1999 gives effect to
the issuance of 500,000 shares of common stock to Snap in November 1999 (Note
11). Upon the closing of HealthGate's anticipated initial public offering, all
shares of redeemable convertible preferred stock outstanding at September 30,
1999 (Note 4) will automatically convert into 7,530,556 shares of common stock.
This conversion has been reflected in the unaudited pro forma balance sheet as
of September 30, 1999.


UNAUDITED INTERIM FINANCIAL DATA AND RESTATEMENT OF THE THREE MONTHS ENDED
  MARCH 31, 1999


    The interim financial data for the nine months ended September 30, 1998 and
1999 have been derived from unaudited financial statements of HealthGate.
Management believes HealthGate's unaudited financial statements have been
prepared on the same basis as the audited financial statements.


    During the three months ended March 31, 1999, HealthGate recognized services
revenue of $82,000 related to two Web site development and hosting arrangements.
During the second quarter of 1999, it was learned that certain material terms
related to advertising and sponsorship commissions guaranteed to the customers
of these sites had not been finalized at March 31, 1999. Accordingly, HealthGate
has restated its results of operations for the three months ended March 31, 1999
to reverse the $82,000 of services revenue related to these sites. These amounts
were recorded as customer deposits. In the opinion of management, all
adjustments necessary to revise the quarterly financial

</TABLE>

ACTUAL AND UNAUDITED PRO FORMA NET LOSS PER SHARE

    Net loss per share is computed in accordance with SFAS No. 128, "Earnings
Per Share." Basic net loss per share is computed by dividing net loss
attributable to common stockholders by the weighted average number of shares of
common stock outstanding. Diluted net loss per share does not differ from basic
net loss per share since potential common shares from conversion of preferred
stock and exercise of stock options and warrants are anti-dilutive for all
periods presented. Unaudited pro forma basic and diluted net loss per share have
been calculated assuming the conversion of all outstanding shares of preferred
stock into common shares, as if the shares had converted immediately upon their
issuance.

COMPREHENSIVE INCOME


    HealthGate adopted SFAS No. 130, "Reporting Comprehensive Income," effective
January 1, 1998. This statement requires a full set of general purpose financial
statements to be expanded to include the reporting of "comprehensive income."
Comprehensive income is comprised of two components, net income and other
comprehensive income. During the years ended December 31, 1996, 1997 and 1998
and the nine months ended September 30, 1998 and 1999, HealthGate had no items
qualifying as other comprehensive income; accordingly, the adoption of SFAS No.
130 had no impact on HealthGate's financial statements.

1. NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
SEGMENT REPORTING

    In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information," which supersedes SFAS No. 14, "Financial
Reporting for Segments of a Business Enterprise." This statement changes the way
public business enterprises report segment information, including financial and
descriptive information about their selected segment information in interim and
annual financial statements. Under SFAS No. 131, operating segments are defined
as revenue-producing components of the enterprise which are generally used
internally for evaluating segment performance. SFAS No. 131 became effective for
HealthGate's fiscal year ended December 31, 1998 and had no effect on
HealthGate's financial position or results of operations. HealthGate operates in
one segment, which is providing healthcare information and related information
to institutions and individuals through the Internet.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." The new standard establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. SFAS No. 133 is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000. HealthGate does
not expect SFAS No. 133 to have a material effect on its financial position or
results of operations.

2. FIXED ASSETS

    Fixed assets consist of the following:

3. NOTES PAYABLE

    On March 26, 1998, HealthGate issued a $2,000,000 subordinated note payable
(the "Note") with detachable warrants, for net cash proceeds of approximately
$1,929,000. The Note bears interest at an annual rate of 13.0%, payable monthly.
The principal amount is due on March 26, 2003, but may be prepaid without
penalty. The Note is secured by substantially all of HealthGate's tangible and
intangible assets, and limits HealthGate's ability to issue additional debt.

    In connection with the Note, HealthGate issued warrants to purchase 341,076
shares of its common stock at an exercise price per share of $.00005. Further,
on December 31, 1998, HealthGate issued warrants to purchase an additional
114,816 shares at an exercise price of $.00005 per share, as HealthGate did not
achieve a minimum 1998 revenue target defined in the agreement. Under the terms
of the Note agreement, HealthGate will be required to issue warrants to purchase
an additional 178,470 shares, 184,221 shares and 190,170 shares at an exercise
price of $.00005 per share if the Note is outstanding on March 26, 2000, 2001
and 2002, respectively. The number of shares and exercise price of the issued
and contingently issuable warrants are to be adjusted for certain dilutive and
anti-dilutive events. The warrants are exercisable for a period of ten years
from March 26, 1998. The terms of the warrant agreement place certain
restrictions on the number of options, warrants and other convertible securities
which HealthGate may issue. These restrictions will expire upon an initial
public offering of HealthGate's common stock. HealthGate ascribed a value of
$261,000 to the warrants issued in March 1998 and $293,000 to the warrants
issued in December 1998, based on the fair value at the time of issuance. The
amount which was ascribed to the warrants was recorded as additional paid-in
capital and a discount from the face value of the Note. The discount is being
amortized to interest expense over the life of the note using the effective
interest method.

    On September 29, 1998, the Company issued a convertible note (the
"Convertible Note") in the principal amount of $2,000,000 to an existing
preferred stockholder. The Convertible Note bore interest at an annual rate of
12%, and was due on March 31, 1999. In April 1999, the Convertible Note was
converted into 174,729 shares of the HealthGate's Series E redeemable
convertible preferred stock (Note 4). Since the Convertible Note was converted
into preferred stock in April 1999, it has been classified as long-term in
HealthGate's balance sheet at December 31, 1998.

CONVERSION


    Each preferred share is convertible into common stock at the option of the
preferred stockholder or automatically upon the closing of an initial public
offering of HealthGate's common stock in which proceeds from the public equal or
exceed $10,000,000. The number of common shares to which a holder of the
preferred stock is entitled upon conversion is based upon the conversion rates
defined by HealthGate's Amended and Restated Certificate of Incorporation,
(approximately 1,209.15 for 1, 1,584.02 for 1, 549.89 for 1 and 797.24 for 1 for
holders of Series A, B, C and D preferred stock, respectively, at December 31,
1998). At December 31, 1998, the outstanding preferred stock is convertible into
a total of 4,672,034 common shares. The conversion rates are to be adjusted for
certain dilutive and anti-dilutive events. HealthGate has reserved approximately
1,209,200, 1,584,100, 549,900 and 1,329,000 shares of common stock for the
conversion of Series A, B, C and D preferred stock, respectively.


LIQUIDATION, DISSOLUTION OR WINDING UP OF HEALTHGATE

    In the event of any liquidation, dissolution or winding up of HealthGate,
the holders of Series A, B, C and D preferred stock are entitled to receive, on
a pro-rata basis, $500, $1,600, $1,000 and $1,500 per share, respectively, plus
all accrued and unpaid dividends.

VOTING, REGISTRATION AND OTHER RIGHTS

    The holders of the preferred stock are entitled to vote, together with the
holders of common stock, on all matters submitted to stockholders for a vote.
Each preferred stockholder is entitled to the number of votes equal to the
number of shares of common stock into which each Series A, B, C and D share is
convertible at the time of such vote.

DIVIDENDS

    The holders of the Series A, B, C and D preferred stock are entitled to
receive cumulative annual dividends in the amount of $50, $160, $100 and $150
per share, respectively, whether or not declared by the Board of Directors.
These dividends are payable upon liquidation, dissolution or winding-up of
HealthGate, or upon redemption of the respective preferred stock.

REDEMPTION

    On each of the fifth, sixth and seventh anniversaries of the applicable
series closing date, HealthGate is required to redeem 33-1/3 percent of the
Series A, B, C, D and E preferred stock at a redemption price equal to $500,
$1,600, $1,000 and $1,500 per share, respectively, plus accrued and unpaid
dividends through the redemption date.


    Required redemption amounts for each of the five years following
December 31, 1998, for the preferred stock, excluding any cumulative and unpaid
dividends, are as follows:

ISSUANCE OF PREFERRED STOCK

    In April 1999, HealthGate issued 546,028 shares of newly authorized Series E
redeemable convertible preferred stock to GE Capital Equity Investments, Inc.,
an affiliate of General Electric Company (Note 5), for gross proceeds of
$6,250,000. In connection with the issuance of the Series E preferred stock,
HealthGate paid $300,000 of fees to a placement agent, paid other issue costs of
$111,426, and issued the placement agent a warrant to purchase up to 21,654
shares of HealthGate common stock at an exercise price of $2.89 per share. The
Company has ascribed a value to the warrant of $200,000. The placement fee,
other issue costs and warrant value have been reflected as a reduction of the
proceeds from the Series E preferred stock issuance. An additional 174,729
shares of Series E preferred stock were issued upon conversion of a convertible
note (Note 3). The Series E preferred stock ranks senior in liquidation to other
classes of preferred stock, and has certain veto rights. The Series E preferred
stock accrues cumulative annual dividends at 7% of its liquidation value

4. REDEEMABLE CONVERTIBLE PREFERRED STOCK (CONTINUED)
(initially $8,250,000). The dividends are compounded annually and, unless paid,
are added to the Series E preferred stock liquidation value. The Series E
preferred stock is convertible into a number of shares of common stock
determined by dividing the liquidation value by a conversion price per share of
$2.89. The conversion price is to be adjusted for certain dilutive events.


    When issued, each share of Series E preferred stock was convertible into
3.966 shares of common stock, which represents a discount from the fair value of
common stock on the date of the Series E issuance. The value attributable to
this conversion right represents an incremental yield, or a beneficial
conversion feature, which will be recognized as a return to the preferred
stockholders. This amount, equal to the net proceeds from the Series E offering
of approximately $7,639,000, which includes conversion of the convertible note,
has been recorded as accretion of preferred stock to redemption value in the
consolidated statement of operations in the period ended September 30, 1999, and
represents a non-cash charge in the determination of net loss attributable to
common stockholders.


5. COMMON STOCK AND OTHER STOCKHOLDERS' DEFICIT

COMMON STOCK

    Each share of common stock entitles the holder to one vote on all matters
submitted to a vote of HealthGate's stockholders. Common stockholders are
entitled to receive dividends, if any, as may be declared by the Board of
Directors, subject to any preferential dividend rights of the preferred
stockholders.

    A 50-for-1 split of HealthGate's common stock became effective on January
23, 1998. All shares of common stock, options, and warrants and per share
amounts included in the accompanying financial statements have been adjusted to
give retroactive effect to the stock split for all periods presented.

STOCK OPTION PLANS

    In June 1994, HealthGate adopted the HealthGate Data Corp. 1994 Stock Option
Plan (the "1994 Plan") which provides for the granting of both incentive stock
options and nonqualified options to employees, directors and consultants. The
1994 Plan, as amended, allows for a maximum of 2,577,900 options to purchase
shares of common stock to be issued prior to December 2004. The exercise price
of any incentive stock option granted under the 1994 Plan shall not be less than
the fair market value of the stock on the date of grant, as determined in good
faith by the Board of Directors, or less than 110% of the fair value in the case
of optionees holding more than 10% of the total combined voting power of all
classes of HealthGate's stock. Options granted under the 1994 Plan are
exercisable for a period of not longer than ten years from the date of grant, or
five years in the case of optionees holding more than 10% of the combined voting
power of all classes of HealthGate's stock.

    HealthGate applies APB 25 and related interpretations in accounting for
employee and director options granted under the 1994 Plan. Since inception
(February 8, 1994) through December 31, 1998, no compensation expense has been
recognized for options granted to employees under this plan. During 1996 and
1997, HealthGate granted options to purchase 29,745 and 9,915 shares of common
stock, respectively, to a member of its Board of Directors for consulting
services rendered. The options vested during 1997 and 1998 as the consulting
services were provided. The compensation expense related to these options was
not significant. Had compensation cost attributable to the 1994 Plan and other
options been determined based on the fair value of the options at the grant
date, consistent with

the provisions of FAS 123, HealthGate's net loss and net loss per share would
have been increased to the pro forma amounts indicated below:

    Because the determination of the fair value of all options granted after
HealthGate becomes a public entity will include an expected volatility factor,
additional option grants are expected to be made subsequent to December 31,
1998, and most options vest over several years, the above pro forma effects are
not necessarily indicative of the pro forma effects on future years.

    Under SFAS No. 123, the fair value of each employee option grant is
estimated on the date of grant using the Black-Scholes option pricing model to
apply the minimum value method with the following weighted-average assumptions
used for grants made during the following periods:

DEFERRED COMPENSATION


    During the nine months ended September 30, 1999, HealthGate granted stock
options to purchase 382,806 shares of its common stock with exercise prices
ranging from $.88 to $9.49 per share. HealthGate recorded compensation expense
and deferred compensation relating to these options totaling approximately
$509,000 and $2,307,000, respectively, representing the differences between the
estimated fair market value of the common stock on the date of grant and the
exercise price. Compensation related to options which vest over three years was
recorded as a component of stockholders' deficit and is being amortized over the
vesting periods of the related options.


ISSUANCE OF WARRANT TO RELATED PARTY


    On June 11, 1999, HealthGate entered into a development and distribution
agreement with GE Medical Systems ("GEMS"), an operating division of General
Electric Company and an affiliate of a Series E preferred stock investor
(Note 4). HealthGate believes that this agreement will benefit it through the
association of the GE Medical Systems name with HealthGate in general, and its
CHOICE product in particular, and through the efforts of GE Medical Systems to
distribute both its standard CHOICE product and the GE Medical Systems enhanced
versions of its CHOICE product. Therefore, in connection with this agreement,
HealthGate issued to General Electric Company a warrant to purchase up to
1,189,800 shares of HealthGate's common stock at an exercise price per share of
$9.49. The warrant is immediately exercisable, and has a term of five years. In
the event HealthGate issues common stock or other equity or debt instruments
which are convertible into common stock for an amount less than the current
exercise price of this warrant, then the exercise price and number of shares of
this warrant will be adjusted accordingly. These adjustment provisions terminate
upon the completion of a qualifying initial public offering, as described in the
agreement. However, if HealthGate fails to complete an initial public offering,
a private placement of securities, or a sale of HealthGate by December 31, 1999,
the exercise price will be adjusted to $3.46 per share on January 1, 2000. The
fair value of this warrant was determined to be $10,300,000 using the
Black-Scholes option pricing model, based on the following assumptions: 100%
volatility, a term of 5 years, and an interest rate of 5.6%. In the event the
exercise price of this warrant is adjusted, its fair value will increase. The
value of the warrant has been recorded as marketing and distribution rights, and
will be amortized as a sales and marketing expense on a straight-line basis over
the one year contractual term of the related

    Realization of total deferred tax assets is dependent upon the generation of
future taxable income. HealthGate has provided a valuation allowance for the
full amount of its deferred tax assets, since realization of these future
benefits is not sufficiently assured.

    Income taxes computed using the federal statutory income tax rate differs
from HealthGate's effective tax primarily due to the following:

</TABLE>



    At December 31, 1998, HealthGate has net operating loss carryforwards and
research and development tax credit carryforwards of approximately $8,492,000
and $82,000, respectively, available for federal and foreign purposes to reduce
future taxable income and future tax liabilities, respectively. If not utilized,
these carryforwards will expire at various dates ranging from 2010 to 2018.
Under the provisions of the Internal Revenue Code, certain substantial changes
in HealthGate's ownership may have limited, or may limit in the future, the
amount of net operating loss and research and development tax credit
carryforwards which could be used annually to offset future taxable income and
income tax liability. The amount of any annual limitation is determined based
upon HealthGate's value prior to an ownership change.

7. 401(K) PLAN


    During 1996, HealthGate established a defined contribution savings plan
under Section 401(k) of the Internal Revenue Code. This plan covers
substantially all employees who meet minimum age and service requirements and
allows participants to defer a portion of their annual compensation on a pre-
tax basis. Company contributions to the plan may be made at the discretion of
the Board of Directors. There were no contributions made to the plan by
HealthGate during the years ended December 31, 1996, 1997 or 1998 or during the
nine months ended September 30, 1998 or 1999.


8. OTHER RELATED PARTY TRANSACTIONS

    Through December 1998, a stockholder of HealthGate was a partial owner of
the building in which HealthGate leased office space. HealthGate incurred rental
costs of approximately $58,000, $84,000 and $89,000 under this lease agreement
during the years ended December 31, 1996, 1997 and 1998, respectively.

    In connection with the Series B preferred stock purchase agreement,
HealthGate was required to use the services of the sole Series B investor for
certain consulting work. During 1996, HealthGate incurred consulting costs with
this investor totaling approximately $203,000. HealthGate also leases certain
computer equipment from this investor under a noncancelable capital lease
arrangement. Payments under this lease during the years ended December 31, 1996,
1997 and 1998 totaled approximately $90,900, $1,500 and $7,500, respectively.

    In May 1998, HealthGate purchased certain fixed assets from an employee in
connection with total consideration of $70,000.


    In addition, during the nine months ended September 30, 1999, HealthGate
paid a referral fee of $68,000 to a related party in connection with the
addition of certain content sources.


9. COMMITMENTS AND CONTINGENCIES

    As of September 30, 1999, HealthGate had outstanding commitments under
capital leases of $890,000 and under operating leases for equipment and office
space of $568,000.



    HealthGate has entered into agreements to license content for its services
from various unrelated third parties. Future minimum license payments under
these agreements as of September 30, 1999 totaled approximately $1,609,000,
which includes annual payments of $500,000 for two years for a content
development and distribution agreement with the New England Journal of Medicine.


    On July 27, 1999, HealthGate received a letter alleging that HealthGate's
Web site induces users to infringe a patent held by a company (the "Holder"). In
lieu of pursuing a patent infringement claim against HealthGate, the Holder
offered to provide HealthGate with a license for unlimited use of the patent for
a one-time payment of between $50,000 and $150,000. HealthGate is currently
investigating this matter. At this time, HealthGate is unable to predict its
outcome.

10. GEOGRAPHIC AND SEGMENT INFORMATION

    HealthGate operates in one segment, which is providing healthcare and

United States for all periods presented.

11. SUBSEQUENT EVENTS


    In November 1999, HealthGate entered a marketing and reseller agreement with
Columbia Information Systems. HealthGate believes that this agreement will
benefit it through the general association of the Columbia Information Systems
and Columbia/HCA names with HealthGate, through the right to make a first offer
to provide services for adding additional content to the Columbia Information
Systems health portal site and any Web sites owned or operated by Columbia/HCA
or their controlled affiliates, and, among other things, through the efforts of
Columbia Information Systems to distribute HealthGate products. In connection
with this agreement, HealthGate issued a warrant to CIS Holdings, Inc., a
related party, for the purchase of up to 1,941,035 shares of HealthGate's common
stock. CIS Holdings, Inc. is an indirect, wholly-owned subsidiary Columbia/HCA
Healthcare Corporation and an affiliate of Columbia Information Systems. The
warrant has a term of three years, and will be exercisable on the earlier to
occur of the consummation of HealthGate's initial public offering, a qualifying
earlier private placement of securities or sale of HealthGate, or March 31,
2000. The exercise price per share will be equal to our initial public offering
price. If an initial public

11. SUBSEQUENT EVENTS (CONTINUED)

offering is not completed by March 31, 2000, the exercise price per share will
be the common equivalent price per share received by HealthGate in its next
qualifying private placement, as defined in the warrant agreement. If neither an
initial public offering nor a qualifying private placement occur before March
31, 2000, the exercise price per share will be adjusted to $3.46 on March 31,
2000. In the event HealthGate issues common stock or other equity or debt
instruments which are convertible into common stock for an amount less than the
current exercise price, then the exercise price and number of shares of this
warrant will be adjusted accordingly. These adjustment provisions will terminate
upon the completion of an initial public offering. If HealthGate is sold prior
to the consummation of its initial public offering or a qualifying private
placement, the exercise price will be adjusted to $3.46 per share, effective
with such sale. The value of this warrant will be recorded as marketing and
distribution rights, and will be amortized as a sales and marketing expense on a
straight-line basis over the three year contractual term of the related
marketing and reseller agreement.



    In October 1999, HealthGate entered into a three-year strategic alliance
agreement with Snap! LLC and Xoom.com, Inc. Under this agreement, Snap will
provide various services to promote HealthGate's name, its www.healthgate.com
Web site, its co-branded CHOICE Web sites and the products and services
HealthGate offers. In exchange for the services provided to HealthGate by Snap
during the first year of the agreement, HealthGate has agreed to pay Snap a
minimum fee of $10,000,000 in cash and has issued 500,000 shares of HealthGate
common stock, plus a $250,000 production and content integration fee. The value
of these shares was determined to be $4,500,000 on the date issued. HealthGate
has agreed to pay Snap minimum fees of $15,000,000 in cash in each of the second
and third years of the agreement for the services provided to HealthGate by Snap
in those years. HealthGate has also agreed to pay Snap up to an additional
$5,000,000 in the first year, $10,000,000 in the second year and $15,000,000 in
the third year of the agreement if Snap delivers more than certain minimum
click-throughs to the co-branded Snap/HealthGate Web site in the respective
years. Either Snap or HealthGate may terminate this agreement if the other party
commits a material breach. If Snap terminates the agreement based on certain
material breaches caused by HealthGate, HealthGate has agreed to continue to pay
Snap 55% of all fees payable by HealthGate under the agreement for the remaining
term of the agreement. If Snap terminates the agreement because HealthGate's
registration statement filed with the Securities and Exchange Commission in
connection with its contemplated initial public offering is not effective on or
before February 28, 2000 or because HealthGate fails to issue to Snap the shares
of common stock as provided in the agreement, HealthGate has agreed to enter
into an agreement with Snap to purchase $450,000 of advertising impressions from
Snap. If Snap and Xoom have not combined with certain assets of NBC to form NBC
Internet on or before March 31, 2000, HealthGate may terminate the agreement and
Snap must return to HealthGate all payments, including the common stock
HealthGate has issued to them as partial payment for the first year minimum fee,
made prior to the termination. National Broadcasting Company, Inc., a subsidiary
of General Electric, owns a majority interest in Snap.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Article IX of HealthGate's Restated Charter provides as follows:

    To the maximum extent permitted by the General Corporation Law of the State
of Delaware as the same exists or may hereafter be amended, no director of the
Corporation shall be personally liable to the Corporation or to any of its
stockholders for monetary damages arising out of such director's breach of
fiduciary duty as a director of the Corporation. No amendment to or repeal of
the provisions of this paragraph shall apply to or have any effect on the
liability or the alleged liability of any director of the Corporation with
respect to any act or failure to act of such director occurring prior to such
amendment or repeal.

    Section 10 of HealthGate's Restated Bylaws provides as follows:

    Section 10. INDEMNIFICATION

    10.1 Officers, Directors and Others. Each person who was or is made a party
or is threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he, or a person of whom
he or she is the legal representative, is or was a director or officer of the
corporation or is or was serving at the request of the corporation as a
director, officer, employee, fiduciary, or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, shall be indemnified and
held harmless by the corporation to the fullest extent which it is empowered to
do so unless prohibited from doing so by the General Corporation Law of the
State of Delaware, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
corporation to provide broader indemnification rights than said law permitted
the corporation to provide prior to such amendment) against all expense,
liability and loss (including attorneys' fees actually and reasonably incurred
by such person in connection with such proceeding) and such indemnification
shall inure to the benefit of his or her heirs, executors and administrators;
provided, however, that, except as provided in Section 10.2 hereof, the
corporation shall indemnify any such person seeking indemnification in
connection with a proceeding initiated by such person only if such proceeding
was authorized by the board of directors. The right to indemnification conferred
in this Section 10 shall be a contract right and, subject to Sections 10.2 and
10.5 hereof, shall include the right to be paid by the corporation the expenses
incurred in defending any such proceeding in advance of its final disposition.
The corporation may, by action of the board of directors, provide

                                      II-1
<PAGE>
indemnification to employees and agents of the corporation with the same scope
and effect as the foregoing indemnification of directors and officers.

    10.2 Procedure; Timing. Any indemnification of a director or officer of the
corporation under Section 10.1 or advance of expenses under Section 10.5 shall
be made promptly, and in any event within thirty days, upon the written request
of the director or officer. If a determination by the corporation that the
director or officer is entitled to indemnification pursuant to this Section 10
is required, and the corporation fails to respond within sixty days to a written
request for indemnity, the corporation shall be deemed to have approved the
request. If the corporation denies a written request for indemnification or
advancing of expenses, in whole or in part, or if payment in full pursuant to
such request is not made within thirty days, the right to indemnification or
advances as granted by this Section 10 shall be enforceable by the director or
officer in any court of competent jurisdiction. Such person's costs and expenses
incurred in connection with successfully establishing his or her right to
indemnification, in whole or in part, in any such action shall also be
indemnified by the corporation. It shall be a defense to any such action (other
than an action brought to enforce a claim for expenses incurred in defending any
proceeding in advance of its final disposition where the required undertaking,
if any, has been tendered to the corporation) that the claimant has not met the
standards of conduct which make it permissible under the General Corporation Law
of the State of Delaware for the corporation to indemnify the claimant for the
amount claimed, but the burden of such defense shall be on the corporation.
Neither the failure of the corporation (including its board, independent legal
counsel or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in the General Corporation Law of the State of Delaware, nor an actual
determination by the corporation (including its board, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

    10.3 Rights Not Exclusive. The rights to indemnification and the payment of
expenses incurred in defending a proceeding in advance of its final disposition
conferred in this Section 10 shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, provision of the
Restated Certificate, bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.

    10.4 Insurance. The corporation may purchase and maintain insurance on its
own behalf and on behalf of any person who is or was a director, officer,
employee, fiduciary or agent of the corporation 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, whether or not the corporation would have the power to indemnify such
person against such liability under this Section 10.

    10.5 Expenses. Expenses incurred by any person described in Section 10.1 in
defending a proceeding shall be paid by the corporation in advance of such
proceeding's final disposition unless otherwise determined by the board in the
specific case upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that he or she
is not entitled to be indemnified by the corporation. Such expenses incurred by
other employees and agents may be so paid upon such terms and conditions, if
any, as the board deems appropriate.

    10.6 Other Persons. Persons who are not covered by the foregoing provisions
of this Section 10 and who are or were employees or agents of the corporation,
or who are or were serving at the request of the corporation as employees or
agents of another corporation, partnership, joint venture, trust or other
enterprise, may be indemnified to the extent authorized at any time or from time
to time by the board.

    10.7 Contract Right. The provisions of this Section 10 shall be deemed to be
a contract right between the corporation and each director or officer who serves
in any such capacity at any time while

                                      II-2
<PAGE>
this Section 10 and the relevant provisions of the General Corporation Law of
the State of Delaware or other applicable law are in effect, and any repeal or
modification of this Section 10 or any such law shall not affect any rights or
obligations then existing with respect to any state of facts or proceeding then
existing.

    10.8 Use of "corporation". For purposes of this Section 10, references to
"the corporation" 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 any person who 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, member, manager, employee
or agent of another corporation, limited liability company, partnership, joint
venture, trust or other enterprise, shall stand in the same position under this
Section 10 with respect to the resulting or surviving corporation as he or she
would have with respect to such constituent corporation if its separate
existence had continued.

                        OTHER INDEMNIFICATION PROVISIONS

    Section 145 of the Delaware General Corporation Law, as amended, provides
that a corporation has the power to indemnify a director, officer, employee or
agent of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, in any criminal proceeding, if such person
had no reasonable cause to believe his conduct was unlawful; provided that, in
the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent that the adjudicating court determines that such indemnification is
proper under the circumstances.

    Under Section 6(b) of the Underwriting Agreement, the underwriters are
obligated, under certain circumstances, to indemnify directors and officers of
the Registrant against certain liabilities, including liabilities under the
Securities Act. Reference is made to the form of Underwriting Agreement filed as
Exhibit 1.1 hereto.

    The Registrant intends to obtain insurance which insures the officers and
directors of the Registrant against certain losses and which insures the
Registrant against certain of its obligations to indemnify such officers and
directors.

    The Registrant has entered into indemnification agreements with each of its
directors and officers, pursuant to which the Registrant has agreed to indemnify
such directors to the fullest extent permitted by law for amounts paid and
expenses incurred in connection with an action or proceeding to which he or she
is or is threatened to be made a party by reason of such position.

    At present, there is no pending litigation or proceeding involving a
director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any director or officer.

    All other schedules have been intentionally omitted because they are either
not required or the information has been included in the Notes to the

Statement.

ITEM 17. UNDERTAKINGS

    (a) 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 provisions described under "Item
14--Indemnification of Directors and Officers" above, 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.

    (b) 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.

    (c) The undersigned Registrant hereby undertakes to provide to the
underwriter at the closing specified in the underwriting agreements,
certificates in such denominations and registered in such names as required by
the underwriter to permit prompt delivery to each purchaser.

Dear Sirs:

         1. INTRODUCTORY. HealthGate Data Corp., a Delaware corporation (the
"Company"), proposes to issue and sell, pursuant to the terms of this Agreement,
to the several Underwriters named in Schedule A hereto (the "Underwriters")
3,750,000 shares of Common Stock, $0.01 par value (the "Firm Stock") of the
Company. SG Cowen Securities Corporation ("SG Cowen"), Volpe Brown Whelan &
Company and Warburg Dillon Read LLC shall act as representatives (the
"Representatives") of the several Underwriters.

                  The Company also proposes to issue and sell to the several
Underwriters up to an additional 562,500 shares of Common Stock (the "Optional
Stock"), if and to the extent that the Representatives shall have determined to

relating to the Common Stock. The registration statement on Form S-1 (File

and as such prospectus shall have been amended from time to time prior to the
date of the Prospectus.

Agreement and to perform its obligations hereunder (including to issue, sell and

authorized, executed and delivered by the Company and is a valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms, except to the extent that rights to indemnity and contribution
hereunder may be limited by federal or state securities laws or the public
policy underlying such laws.

                  (o) The Company and its subsidiaries are in all material
respects in compliance with, and conduct their business in conformity with, all
applicable federal, state, local and foreign laws, rules and regulations of any
court or governmental agency or body; to the knowledge of the Company, otherwise
than as set forth in the Registration Statement and the Prospectus, no
prospective change in any of such federal or state laws, rules or regulations
has been adopted which, when made effective, would have a material adverse
effect on the operations of the Company and its subsidiaries.

                  (p) Except for an amendment to the Company's 1997 federal tax
return which the Company plans to file, the Company and its subsidiaries have
filed all necessary federal, state, local and foreign income, payroll, franchise
and other tax returns and have paid all taxes shown as due thereon or with
respect to any of their properties, and there is no tax deficiency that has
been, or to the knowledge of the Company is likely to be, asserted against the
Company or any of its subsidiaries or any of their respective properties or
assets that would adversely affect the financial position, business or
operations of the Company and its subsidiaries.

                  (q) No person or entity has the right to require registration
of shares of Common Stock or other securities of the Company because of the
filing or effectiveness of the Registration Statement or otherwise, except for
persons and entities who have expressly waived such right or who have been given
proper notice and have failed to exercise such right within the time or times
required under the terms and conditions of such right.

                  (r) Neither the Company nor any of its officers, directors or
affiliates has taken or will take, directly or indirectly, any action designed
or intended to stabilize or manipulate the price of any security of the Company,
or which caused or resulted in, or which might in the future reasonably be
expected to cause or result in, stabilization or manipulation of the price of
any security of the Company.

                  (s) The Company has provided you with all financial statements
since 1994 to the date hereof that are available to the officers of the Company,
including financial statements for the months of January, February, March,
April, May, June, July, August and September of 1999.

                  (t) The Company and its subsidiaries own or possess the right
to use all patents, trademarks (including "ReADER"), trademark registrations,
service marks (including "HealthGate", "HealthGate Data" and "MedGate"), service
mark registrations, trade names, copyrights, licenses, inventions, trade secrets
and rights described in the Prospectus as being


                                        6

<PAGE>


owned by it or necessary for the conduct of their respective businesses (and the
Company has trademark registration applications pending for the trademarks
"CHOICE" and "activePress", and for the HealthGate logo design), and the Company
is not aware of any claim to the contrary or any challenge by any other person
to the rights of the Company and its subsidiaries with respect to the foregoing.
To the best of the Company's knowledge, the Company's business as now conducted
and as proposed to be conducted does not and will not infringe or conflict with
in any material respect patents, trademarks, service marks, trade names,
copyrights, trade secrets, licenses or other intellectual property or franchise
right of any person. Except as described in the Prospectus, no claim has been
made against the Company alleging the infringement by the Company of any patent,
trademark, service mark, trade name, copyright, trade secret, license in or
other intellectual property right or franchise right of any person.

                  (u) The Company and its subsidiaries have performed all
material obligations required to be performed by them under all contracts
required by Item 601(b)(10) of Regulation S-K under the Securities Act to be
filed as exhibits to the Registration Statement, and neither the Company nor any
of its subsidiaries nor any other party to such contract is in default under or
in breach of any such obligations. Neither the Company nor any of its
subsidiaries has received any notice of such default or breach.

                  (v) The Company has reviewed its operations and that of its
subsidiaries to evaluate the extent to which the business or operations of the
Company or any of its subsidiaries will be affected by the Year 2000 Problem
(that is, any significant risk that computer hardware or software applications
used by the Company and its subsidiaries will not, in the case of dates or time
periods occurring after December 31, 1999, function at least as effectively as
in the case of dates or time periods occurring prior to January 1, 2000); as a
result of such review, (i) the Company has no reason to believe, and does not
believe, that (A) there are any issues related to the Company's preparedness to
address the Year 2000 Problem that are of a character required by, described or
referred to in the Registration Statement or Prospectus which have not been
accurately described in the Registration Statement or Prospectus and (B) the
Year 2000 Problem will have any material adverse change, or any development
involving a prospective material adverse change in or affecting the condition
(financial or otherwise), earnings, business, management, prospects, net worth
or results of operations of the Company and its subsidiaries considered as a
whole, or result in any material loss or interference with the business or
operations of the Company and its subsidiaries, taken as a whole; and (ii) the
Company reasonably believes, after due inquiry, that the licensors, internet
service providers, suppliers, vendors, subscribers or other material third
parties used or served by the Company and such subsidiaries are addressing or
will address the Year 2000 Problem in a timely manner, except to the extent that
a failure to address the Year 2000 Problem by any licensor, internet service
provider, supplier, vendor, subscriber or material third party would not have
any material adverse change, or any development involving a prospective material
adverse change in or affecting the condition (financial or otherwise), earnings,
business, management, prospects, net worth or results of operations of the
Company and its subsidiaries considered as a whole.

                  (w) The Company is not involved in any labor dispute nor is
any such dispute


                                        7

<PAGE>


threatened. The Company is not aware that (A) any executive, key employee or
significant group of employees of the Company or any subsidiary plans to
terminate employment with the Company or any such subsidiary or (B) any such
executive or key employee is subject to any noncompete, nondisclosure,
confidentiality, employment, consulting or similar agreement that would be
violated by the present or proposed business activities of the Company and its
subsidiaries. Neither the Company nor any subsidiary has or expects to have any
liability for any prohibited transaction or funding deficiency or any complete
or partial withdrawal liability with respect to any pension, profit sharing or
other plan which is subject to the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), to which the Company or any subsidiary makes or ever
has made a contribution and in which any employee of the Company or any
subsidiary is or has ever been a participant. With respect to such plans, the
Company and each subsidiary is in compliance in all material respects with all
applicable provisions of ERISA.

                  (x) The Company has obtained the written agreement described
in Section 8(j) of this Agreement from each of its officers, directors,
principal stockholders and other existing holders of Common Stock as set forth
on Schedule B attached hereto.

                  (y) The Company and its subsidiaries have, and the Company and
its subsidiaries as of the Closing Date will have, good and marketable title in
fee simple to all real property and good and marketable title to all personal
property owned or proposed to be owned by them which is material to the business
of the Company and its subsidiaries, in each case free and clear of all liens,
encumbrances and defects except such as are described in the Prospectus or such
as would not materially affect the value of such property and would not
interfere with the use made and proposed to be made of such property by the
Company and its subsidiaries and would not have a material adverse effect on the
Company and its subsidiaries considered as a whole; and any real property and
buildings held under lease by the Company and its subsidiaries or proposed to be
held after giving effect to the transactions described in the Prospectus are, or
will be as of the Closing Date, held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and buildings by the
Company and its subsidiaries, and as would not have a material adverse effect on
the Company and its subsidiaries considered as a whole, in each case except as
described in or contemplated by the Prospectus.

                  (z) The Company and its subsidiaries are insured by insurers
of recognized financial responsibility against such losses and risks and in such
amounts as are prudent and customary in the businesses in which they are engaged
or propose to engage after giving effect to the transactions described in the
Prospectus; and neither the Company nor any subsidiary of the Company has any
reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue their business at a cost that
would not materially and adversely affect the condition, financial or otherwise,
or the earnings, business or operations of the Company and its subsidiaries
considered as a whole, except as described in or contemplated by the Prospectus.

                  (aa) Other than as contemplated by this Agreement, there is no
broker, finder


                                        8

<PAGE>


or other party that is entitled to receive from the Company any brokerage or
finder's fee or other fee or commission as a result of any of the transactions
contemplated by this Agreement.

                  (bb) The Company and each of its subsidiaries maintain a
system of internal accounting controls sufficient to provide reasonable
assurances that (i) the Company has adequately addressed the material weaknesses
in the Company's internal accounting controls identified by
PricewaterhouseCoopers LLC in its letter to the Company dated June 30, 1999;
(ii) transactions are executed in accordance with management's general or
specific authorization; (iii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain accountability for assets; (iv) access to
assets is permitted only in accordance with management's general or specific
authorization; and (v) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

                  (cc) To the Company's knowledge, neither the Company nor any
of its subsidiaries nor any employee or agent of the Company or any of its
subsidiaries has made any payment of funds of the Company or any of its
subsidiaries or received or retained any funds in violation of any law, rule or
regulation, which payment, receipt or retention of funds is of a character
required to be disclosed in the Prospectus.

                  (dd) Neither the Company nor any of its subsidiaries is or,
after application of the net proceeds of this offering as described under the
caption "Use of Proceeds" in the Prospectus, will become an "investment company"
or an entity "controlled" by an "investment company" as such terms are defined
in the Investment Company Act of 1940, as amended.

                  (ee) Each certificate signed by any officer of the Company and
delivered to the Underwriters or counsel for the Underwriters shall be deemed to
be a representation and warranty by the Company as to the matters covered
thereby.

                  3. PURCHASE BY, AND SALE AND DELIVERY TO, THE UNDERWRITERS.
The Company agrees to sell to the Underwriters, and each Underwriter, on the
basis of the representations, warranties, covenants and agreements herein
contained, but subject to the terms and conditions herein set forth, agrees,
severally and not jointly, to purchase from the Company, the respective numbers
of Firm Stock set forth in Schedule A hereto opposite its names, subject to
adjustment in accordance with Section 12 hereof, at U.S.$ _______ per share (the
"Purchase Price").

                  The Company will deliver the Firm Stock to the Representatives
for the respective accounts of the several Underwriters in the form of
definitive certificates, issued in such names and in such denominations as the
Representatives may direct by notice in writing to the Company given at or prior
to 12:00 Noon, New York Time, on the second full business day preceding the
First Closing Date (as defined below) or, if no such direction is received, in
the names of the respective Underwriters or in such other names as the
Representatives may designate (solely for the purpose of administrative
convenience) and in such denominations as the Representatives may determine,
against payment of the aggregate Purchase Price therefor in


                                        9

<PAGE>


immediately available funds (same day funds), all at the offices of Shearman &
Sterling, 599 Lexington Avenue, New York, New York 10022. The time and date of
the delivery and closing shall be at 10:00 A.M., New York Time, on _________,
1999, in accordance with Rule 15c6-1 of the Exchange Act. The time and date of
such payment and delivery are herein referred to as the "First Closing Date".
The First Closing Date and the location of delivery of, and the form of payment
for, the Firm Stock may be varied by agreement among the Company and the
Representatives. The First Closing Date may be postponed pursuant to the
provisions of Section 12.

                  The Company shall make the certificates for the Firm Stock
available to the Representatives for examination on behalf of the Underwriters
not later than 10:00 A.M., New York Time, on the business day preceding the
First Closing Date at the offices of SG Cowen, Financial Square, New York, New
York 10005.

                  It is understood that SG Cowen, individually and not as a
Representative of the several Underwriters, may (but shall not be obligated to)
make payment to the Company on behalf of any Underwriter or Underwriters, for
the Common Stock to be purchased by such Underwriter or Underwriters. Any such
payment by SG Cowen shall not relieve such Underwriter or Underwriters from any
of its or their other obligations hereunder.

                  The several Underwriters agree to make an initial public
offering of the Firm Stock at the initial public offering price as soon after
the effectiveness of the Registration Statement as in their judgment is
advisable. The Representatives shall promptly advise the Company of the making
of the initial public offering. The Company is advised by you that the Firm
Stock is to be offered to the public initially at U.S.$ ______ a share (the
"Public Offering Price") and to certain dealers selected by you at a price that
represents a concession not in excess of U.S.$ ____ a share under the Public
Offering Price, and that any Underwriter may allow, and such dealers may
reallow, a concession, not in excess of U.S.$ _____ a share, to any Underwriter
or to certain other dealers.

                  For the purpose of covering any over-allotments in connection
with the distribution and sale of the Firm Stock as contemplated by the
Prospectus, the Company hereby grants to the Underwriters an option to purchase,
severally and not jointly, up to 562,500 shares of Optional Stock. The price per
share to be paid for the Optional Stock shall be the Purchase Price. The option
granted hereby may be exercised as to all or any part of the Optional Stock at
any time, and from time to time, not more than thirty (30) days subsequent to
the effective date of this Agreement. No Optional Stock shall be sold and
delivered unless the Firm Stock previously has been, or simultaneously is, sold
and delivered. The right to purchase the Optional Stock or any portion thereof
may be surrendered and terminated at any time upon notice by the Underwriters to
the Company.

                  The option granted hereby may be exercised by the Underwriters
by giving written notice from SG Cowen to the Company setting forth the number
of shares of the Optional Stock to be purchased by the Underwriters and the date
and time for delivery of and payment for


                                       10

<PAGE>


the Optional Stock. Each date and time for delivery of and payment for the
Optional Stock (which may be the First Closing Date, but not earlier) is herein
called the "Option Closing Date" and shall in no event be earlier than two (2)
business days nor later than ten (10) business days after written notice is
given. (The Option Closing Date and the First Closing Date are herein called the
"Closing Dates".) Optional Stock shall be purchased for the account of each
Underwriter in the same proportion as the number of shares of Firm Stock set
forth opposite such Underwriter's name in Schedule A hereto bears to the total
number of shares of Firm Stock (subject to adjustment by the Underwriters to
eliminate odd lots). Upon exercise of the option by the Underwriters, the
Company agrees to sell to the Underwriters the number of shares of Optional
Stock set forth in the written notice of exercise and the Underwriters agree,
severally and not jointly and subject to the terms and conditions herein set
forth, to purchase the number of such shares determined as aforesaid.

                  The Company will deliver the Optional Stock to the
Underwriters in the form of definitive certificates, issued in such names and in
such denominations as the Representatives may direct by notice in writing to the
Company given at or prior to 12:00 Noon, New York Time, on the second full
business day preceding the Option Closing Date or, if no such direction is
received, in the names of the respective Underwriters or in such other names as
SG Cowen may designate (solely for the purpose of administrative convenience)
and in such denominations as SG Cowen may determine, against payment of the
aggregate Purchase Price therefor in immediately available funds, at the offices
of Shearman & Sterling, 599 Lexington Avenue, New York, New York 10022. The
Company shall make the certificates for the Optional Stock available to the
Underwriters for examination not later than 10:00 A.M., New York Time, on the
business day preceding the Option Closing Date at the offices of SG Cowen,
Financial Square, New York, New York 10005. The Option Closing Date and the
location of delivery of, and the form of payment for, the Option Stock may be
varied by agreement between among the Company and SG Cowen. The Option Closing
Date may be postponed pursuant to the provisions of Section 12.

                  4. COVENANTS AND AGREEMENTS OF THE COMPANY. The Company
covenants and agrees with the several Underwriters that:

                  (a) The Company will (i) if the Company and the
Representatives have determined not to proceed pursuant to Rule 430A of the
Rules and Regulations, use its best efforts to cause the Registration Statement
to become effective, (ii) if the Company and the Representatives have determined
to proceed pursuant to Rule 430A of the Rules and Regulations, use its best
efforts to comply with the provisions of and make all requisite filings with the
Commission pursuant to Rule 430A and Rule 424 of the Rules and Regulations and
(iii) if the Company and the Representatives have determined to deliver a
Prospectus pursuant to Rule 434 of the Rules and Regulations, to use its best
efforts to comply with all the applicable provisions thereof. The Company will
advise the Representatives promptly as to the time at which the Registration
Statement becomes effective, will advise the Representatives promptly of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of the institution of any proceedings for that
purpose, and will use its best efforts to prevent the issuance of any such stop
order and to obtain as soon as possible the lifting thereof, if


                                       11

<PAGE>


issued. The Company will advise the Representatives promptly of the receipt of
any comments of the Commission or any request by the Commission for any
amendment of or supplement to the Registration Statement or the Prospectus or
for additional information and will not at any time file any amendment to the
Registration Statement or supplement to the Prospectus which shall not
previously have been submitted to the Representatives a reasonable time prior to
the proposed filing thereof or to which the Representatives shall reasonably
object in writing or which is not in compliance with the Securities Act and the
Rules and Regulations.

                  (b) The Company will prepare and file with the Commission,
promptly upon the request of the Representatives, any amendments or supplements
to the Registration Statement or the Prospectus which in the opinion of the
Representatives may be necessary to enable the several Underwriters to continue
the distribution of the Common Stock and will use its best efforts to cause the
same to become effective as promptly as possible.

                  (c) If at any time after the effective date of the
Registration Statement when a prospectus relating to the Common Stock is
required to be delivered under the Securities Act any event relating to or
affecting the Company or any of its subsidiaries occurs as a result of which the
Prospectus would include an untrue statement of a material fact, or omit to
state any material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, or if, in the
opinion of counsel for the Underwriters, it is necessary at any time to amend or
supplement the Prospectus to comply with applicable law, the Company will
promptly notify the Representatives thereof and will prepare, file with the
Commission and furnish, at its own expense, to the Underwriters and to the
dealers (whose names and addresses you will furnish to the Company) to which
Common Stock may have been sold by you on behalf of the Underwriters and to any
other dealers upon request, either amendments or supplements to the Prospectus
so that the statements in the Prospectus as so amended or supplemented will not,
in the light of the circumstances when the Prospectus is delivered to a
purchaser, be misleading or so that the Prospectus, as amended or supplemented,
will comply with applicable law.

                  (d) The Company will deliver to the Representatives, at or
before the Closing Dates, signed copies of the Registration Statement, as
originally filed with the Commission, and all amendments thereto including all
financial statements and exhibits thereto, and will deliver to the
Representatives such number of copies of the Registration Statement, including
such financial statements but without exhibits, and all amendments thereto, as
the Representatives may reasonably request. The Company will deliver or mail to,
upon the order of the Representatives, from time to time until the effective
date of the Registration Statement, as many copies of the Pre-effective
Prospectus as the Representatives may reasonably request. The Company will
deliver or mail to, upon the order of the Representatives, on the date of the
initial public offering, and thereafter from time to time during the period when
delivery of a prospectus relating to the Common Stock is required under the
Securities Act, as many copies of the Prospectus, in final form or as thereafter
amended or supplemented as the Representatives may reasonably request; provided,
however, that the expense of the preparation and delivery of any prospectus
required for use nine (9) months or more after the effective date of the
Registration Statement shall be borne by the Underwriters required to deliver
such prospectus.


                                       12

<PAGE>


                  (e) The Company will make generally available to its
shareholders as soon as practicable, but not later than fifteen (15) months
after the effective date of the Registration Statement, an earning statement
which will be in reasonable detail (but which need not be audited) and which
will comply with Section 11(a) of the Securities Act, covering a period of at
least twelve (12) months beginning after the "effective date" (as defined in
Rule 158 under the Securities Act) of the Registration Statement.

                  (f) The Company will cooperate with the Representatives to
enable the Common Stock to be registered or qualified for offering and sale by
the Underwriters and by dealers under the securities laws of such jurisdictions
as the Representatives may designate and at the request of the Representatives
will make such applications and furnish such consents to service of process or
other documents as may be required of it as the issuer of the Common Stock for
that purpose; provided, however, that the Company shall not be required to
qualify to do business or to file a general consent (other than that arising out
of the offering or sale of the Common Stock) to service of process in any such
jurisdiction where it is not now so subject. The Company will, from time to
time, prepare and file such statements and reports as are or may be required of
it as the issuer of the Common Stock to continue such qualifications in effect
for so long a period as the Representatives may reasonably request for the
distribution of the Common Stock. The Company will advise the Representatives
promptly after the Company becomes aware of the suspension of the qualifications
or registration of (or any such exception relating to) the Common Stock of the
Company for offering, sale or trading in any jurisdiction or of any initiation
or threat of any proceeding for any such purpose, and in the event of the
issuance of any orders suspending such qualifications, registration or
exception, the Company will, with the cooperation of the Representatives use its
best efforts to obtain the withdrawal thereof.

                  (g) The Company will furnish to its shareholders as soon as
practicable after the end of each fiscal year an annual report containing
financial statements certified by independent public accountants, will furnish
to its shareholders as soon as practicable after the end of each of the first
three quarters of each fiscal year (beginning with the fiscal quarter ending
after the effective date of the Registration Statement) consolidated summary
financial information of the Company and its subsidiaries for such quarter in
reasonable detail.

                  (h) During the period of three (3) years from the date hereof,
the Company will deliver to the Representatives and, upon request, to each of
the other Underwriters, as soon as they are available, copies of each annual
report of the Company, including the opinion thereon of the Company's
independent public accountants, and each other report furnished by the Company
to its shareholders and will deliver to the Representatives, (i) as soon as they
are available, copies of any other reports (financial or other) or
communications which the Company shall publish or otherwise make available to
any of its shareholders as such, (ii) as soon as practicable after the filing
thereof, copies of each proxy statement, Annual Report on Form 10-K, Quarterly
Report on Form 10-Q, Report on Form 8-K or other report and financial statements
filed by the Company with the Commission, or the NASD or any securities exchange
and (iii) from time to time such other information concerning the Company as you
may request. So long as the Company has active subsidiaries, such financial
statements will be on a consolidated basis


                                       13

<PAGE>


to the extent the accounts of the Company and its subsidiaries are consolidated
in reports furnished to its shareholders generally. Separate financial
statements shall be furnished for all subsidiaries whose accounts are not
consolidated but which at the time are significant subsidiaries as defined in
the Rules and Regulations.

                  (i) The Company will use its best efforts to list the Common
Stock, subject to official notice of issuance, on the Nasdaq National Market
concurrently with the effectiveness of the Registration Statement.

                  (j) The Company will maintain a transfer agent and registrar
for its Common Stock.

                  (k) Prior to filing its quarterly statements on Form 10-Q, the
Company will have its independent auditors perform a limited quarterly review of
its quarterly numbers.

                  (l) The Company will not, for a period of 180 days following
the date of the final prospectus filed by the Company with the Securities and
Exchange Commission in connection with such public offering without the prior
written consent of SG Cowen, on behalf of the several Underwriters, (1) directly
or indirectly, offer, sell, assign, transfer, encumber, pledge, contract to
sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, lend, or otherwise
dispose of, other than by operation of law, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock
(including, without limitation, Common Stock which may be deemed to be
beneficially owned by the undersigned in accordance with the rules and
regulations promulgated under the Securities Act) or (2) enter into any swap or
other arrangement that transfers to another, in whole or in part, any of the
economic consequences of ownership of Common Stock whether any such transaction
described in clause (1) or (2) above is to be settled by delivery of Common
Stock or such other securities, in cash or otherwise, other than the Company's
sale of Common Stock hereunder, the Company's issuance of stock options under
the Company's 1994 Stock Option Plan, and the Company's issuance of Common Stock
upon the exercise of warrants and stock options which are presently outstanding
and described in the Prospectus.

                  (m) The Company will apply the net proceeds from the sale of
the Common Stock as set forth in the description under "Use of Proceeds" in the
Prospectus, which description complies in all respects with the requirements of
Item 504 of Regulation S-K.

                  (n) The Company will supply you with copies of all
correspondence to and from, and all documents issued to and by, the Commission
in connection with the registration of the Common Stock under the Securities
Act.

                  (o) Prior to each of the Closing Dates the Company will
furnish to you, as soon as they have been prepared, copies of any unaudited
interim consolidated financial statements of the Company and its subsidiaries
for any periods subsequent to the periods covered


                                       14

<PAGE>


by the financial statements appearing in the Registration Statement and the
Prospectus.

                  (p) Prior to each of the Closing Dates the Company will issue
no press release or other communications directly or indirectly and hold no
press conference with respect to the Company or any of its subsidiaries, the
financial condition, results of operations, business, prospects, assets or
liabilities of any of them, or the offering of the Common Stock, without your
prior written consent. For a period of twelve (12) months following the first
Closing Date, the Company will use its best efforts to provide to you copies of
each press release or other public communications with respect to the financial
condition, results of operations, business, prospects, assets or liabilities of
the Company at least twenty-four (24) hours prior to the public issuance thereof
or such longer advance period as may reasonably be practicable.

                  5. PAYMENT OF EXPENSES. (a) The Company will pay (directly or
by reimbursement) all costs, fees and expenses incurred in connection with
expenses incident to the performance of the obligations of the Company under
this Agreement and in connection with the transactions contemplated hereby,
including but not limited to (i) all expenses and taxes incident to the issuance
and delivery of the Common Stock to the Representatives; (ii) all expenses
incident to the registration of the Common Stock under the Securities Act; (iii)
the costs of preparing stock certificates (including printing and engraving
costs); (iv) all fees and expenses of the registrar and transfer agent of the
Common Stock; (v) all necessary issue, transfer and other stamp taxes in
connection with the issuance and sale of the Common Stock to the Underwriters;
(vi) fees and expenses of the Company's counsel and the Company's independent
accountants; (vii) all costs and expenses incurred in connection with the
preparation, printing filing, shipping and distribution of the Registration
Statement, each Pre-effective Prospectus and the Prospectus (including all
exhibits and financial statements) and all amendments and supplements provided
for herein, the "Agreement Among Underwriters" between the Representatives and
the Underwriters, the Master Selected Dealers' Agreement, the Underwriters'
Questionnaire and the Blue Sky memoranda (including related fees and expenses of
counsel to the Underwriters) and this Agreement; (viii) all filing fees,
attorneys' fees and expenses incurred by the Company or the Underwriters in
connection with exemptions from the qualifying or registering (or obtaining
qualification or registration of) all or any part of the Common Stock for offer
and sale under the Blue Sky or other securities laws of such jurisdictions as
the Representatives may designate; (ix) all fees and expenses paid or incurred
in connection with filings made with the NASD; (x) all fees and expenses paid or
incurred in connection with listing the Common Stock on Nasdaq; (xi) the
Company's expenses incurred in connection with the roadshow; and (xii) all other
costs and expenses incident to the performance of their obligations hereunder
which are not otherwise specifically provided for in this Section.

                  (b) In addition to its other obligations under Section 6(a)
hereof, the Company agrees that, as an interim measure during the pendency of
any claim, action, investigation, inquiry or other proceeding arising out of or
based upon (i) any statement or omission or any alleged statement or omission,
(ii) any act or failure to act or any alleged act or failure to act or (iii) any
breach or inaccuracy in their representations and warranties, it will reimburse
each Underwriter (and to the extent applicable, each officer, director, or
controlling person) on a


                                       15

<PAGE>


quarterly basis for all reasonable legal or other expenses incurred in
connection with investigating or defending any such claim, action,
investigation, inquiry or other proceeding, notwithstanding the absence of a
judicial determination as to the propriety and enforceability of the Company's
obligation to reimburse each Underwriter for such expenses and the possibility
that such payments might later be held to have been improper by a court of
competent jurisdiction. To the extent that any such interim reimbursement
payment is so held to have been improper, each Underwriter shall promptly return
it to the Company, together with interest, compounded daily, determined on the
basis of the prime rate (or other commercial lending rate for borrowers of the
highest credit standing) announced from time to time by _______, New York, New
York (the "Prime Rate"). Any such interim reimbursement payments which are not
made to an Underwriter in a timely manner as provided below shall bear interest
at the Prime Rate from the due date for such reimbursement. This expense
reimbursement agreement will be in addition to any other liability which the
Company may otherwise have. The request for reimbursement will be sent to the
Company.

                  (c) In addition to its other obligations under Section 6(b)
hereof, each Underwriter severally agrees that, as an interim measure during the
pendency of any claim, action, investigation, inquiry or other proceeding
arising out of or based upon any statement or omission, or any alleged statement
or omission, described in Section 6(d) hereof which relates to information
furnished to the Company pursuant to Section __ hereof, it will reimburse the
Company (and, to the extent applicable, each officer, director, or controlling
person) on a quarterly basis for all reasonable legal or other expenses incurred
in connection with investigating or defending any such claim, action,
investigation, inquiry or other proceeding, notwithstanding the absence of a
judicial determination as to the propriety and enforceability of the
Underwriters' obligation to reimburse the Company (and, to the extent
applicable, each officer, director, or controlling person) for such expenses and
the possibility that such payments might later be held to have been improper by
a court of competent jurisdiction. To the extent that any such interim
reimbursement payment is so held to have been improper, the Company (and, to the
extent applicable, each officer, director, or controlling person) shall promptly
return it to the Underwriters together with interest, compounded daily,
determined on the basis of the Prime Rate. Any such interim reimbursement
payments which are not made to the Company within thirty (30) days of a request
for reimbursement shall bear interest at the Prime Rate from the date of such
request. This indemnity agreement will be in addition to any liability which
such Underwriter may otherwise have.


                  (d) It is agreed that any controversy arising out of the
operation of the interim reimbursement arrangements set forth in paragraph (b)
and/or (c) of this Section 5, including the amounts of any requested
reimbursement payments and the method of determining such amounts, shall be
settled by arbitration conducted under the provisions of the Constitution and
Rules of the Board of Governors of the New York Stock Exchange, Inc. or pursuant
to the Code of Arbitration Procedure of the NASD. Any such arbitration must be
commenced by service of a written demand for arbitration or written notice of
intention to arbitrate, therein electing the arbitration tribunal. In the event
the party demanding arbitration does not make such designation of an arbitration
tribunal in such demand or notice, then the party responding to said demand or
notice is authorized to do so. Such an arbitration would be limited to the
operation of the interim reimbursement provisions contained in paragraph (b) of
this Section 5 and would not resolve the


                                       16

<PAGE>


ultimate propriety or enforceability of the obligation to reimburse expenses
which is created by the provisions of Section 6.

                  6. INDEMNIFICATION AND CONTRIBUTION. (a) The Company agrees to
indemnify and hold harmless each Underwriter and each person, if any, who
controls such Underwriter within the meaning of the Securities Act and the
respective officers, directors, partners, employees, representatives and agents
of each of such Underwriter (collectively, the "Underwriter Indemnified Parties"
and, each, an "Underwriter Indemnified Party"), against any losses, claims,
damages, liabilities or expenses (including the reasonable cost of investigating
and defending against any claims therefor and counsel fees incurred in
connection therewith), joint or several, which may be based upon the Securities
Act, or any other statute or at common law, (i) on the ground or alleged ground
that any Pre-effective Prospectus, the Registration Statement or the Prospectus
(or any Pre-effective Prospectus, the Registration Statement or the Prospectus
as from time to time amended or supplemented) includes or allegedly includes an
untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading, unless
such statement or omission was made in reliance upon, and in conformity with,
written information furnished to the Company by any Underwriter, directly or
through the Representatives, specifically for use in the preparation thereof or
(ii) for any act or failure to act or any alleged act or failure to act by any
Underwriter in connection with, or relating in any manner to, the Common Stock
or the offering contemplated hereby, and which is included as part of or
referred to in any loss, claim, damage, liability or expense arising out of or
based upon matters covered by clause (i) above (provided that the Company shall
not be liable under this clause (ii) to the extent that it is determined in a
final judgment by a court of competent jurisdiction that such loss, claim,
damage, or liability or expense resulted directly from any such acts or failures
to act undertaken or omitted to be taken by such Underwriter through its gross
negligence or willful misconduct). The Company will be entitled to participate
at its own expense in the defense or, if it so elects, to assume the defense of
any suit brought to enforce any such liability, but if the Company elects to
assume the defense, such defense shall be conducted by counsel chosen by it and
reasonably acceptable to the Underwriters. In the event the Company elects to
assume the defense of any such suit and retain such counsel, any Underwriter
Indemnified Parties, defendant or defendants in the suit, may retain additional
counsel but shall bear the fees and expenses of such counsel unless (i) the
Company shall have specifically authorized the retaining of such counsel or (ii)
the parties to such suit include any such Underwriter Indemnified Parties, and
the Company and such Underwriter Indemnified Parties at law or in equity have
been advised by counsel to the Underwriters that one or more legal defenses may
be available to it or them which may not be available to the Company, in which
case the Company shall not be entitled to assume the defense of such suit
notwithstanding its obligation to bear the fees and expenses of such counsel,
provided that the Company shall not, in connection with any proceeding or
related proceeding in the same jurisdiction, be liable for the fees and expenses
of more than one separate firm representing the Underwriter; provided, further,
that in no case is the Company to be liable with respect to any claims made
against the Underwriter unless the Underwriter shall have notified the Company
in writing within a reasonable time after the summons or other first legal
process giving information of the nature of the claim shall have been served
upon the Underwriter, but failure to notify the Company of such


                                       17

<PAGE>


claim shall not relieve it from any liability which it may have to the
Underwriter otherwise than on account of its indemnity agreement contained in
this paragraph. This indemnity agreement is not exclusive and will be in
addition to any liability which the Company might otherwise have and shall not
limit any rights or remedies which may otherwise be available at law or in
equity to each Underwriter Indemnified Party.

                  (b) Each Underwriter severally and not jointly agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed the Registration Statement and each person, if any, who
controls the Company within the meaning of the Securities Act (collectively, the
"Company Indemnified Parties"), against any losses, claims, damages, liabilities
or expenses (including, unless the Underwriter or Underwriters elect to assume
the defense, the reasonable cost of investigating and defending against any
claims therefor and counsel fees incurred in connection therewith), joint or
several, which arise out of or are based in whole or in part upon the Securities
Act, the Exchange Act or any other federal, state, local or foreign statute or
regulation, or at common law, on the ground or alleged ground that any
Pre-effective Prospectus, the Registration Statement or the Prospectus (or any
Pre-effective Prospectus, the Registration Statement or the Prospectus, as from
time to time amended and supplemented) includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
in which they were made, not misleading, but only insofar as any such statement
or omission was made in reliance upon, and in conformity with, written
information furnished to the Company by such Underwriter, directly or through
the Representatives, specifically for use in the preparation thereof; provided,
however, that in no case is such Underwriter to be liable with respect to any
claims made against any Company Indemnified Party against whom the action is
brought unless such Company Indemnified Party shall have notified such
Underwriter in writing within a reasonable time after the summons or other first
legal process giving information of the nature of the claim shall have been
served upon the Company Indemnified Party, but failure to notify such
Underwriter of such claim shall not relieve it from any liability which it may
have to any Company Indemnified Party otherwise than on account of its indemnity
agreement contained in this paragraph. Such Underwriter shall be entitled to
participate at its own expense in the defense, or, if it so elects, to assume
the defense of any suit brought to enforce any such liability, but, if such
Underwriter elects to assume the defense, such defense shall be conducted by
counsel chosen by it. In the event that any Underwriter elects to assume the
defense of any such suit and retain such counsel, the Company Indemnified
Parties and any other Underwriter or Underwriters or controlling person or
persons, defendant or defendants in the suit, shall bear the fees and expenses
of any additional counsel retained by them, respectively. The Underwriter
against whom indemnity may be sought shall not be liable to indemnify any person
for any settlement of any such claim effected without such Underwriter's
consent. This indemnity agreement is not exclusive and will be in addition to
any liability which such Underwriter might otherwise have and shall not limit
any rights or remedies which may otherwise be available at law or in equity to
any Company Indemnified Party;

                  (c) If the indemnification provided for in this Section 6 is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages,
liabilities or expenses (or actions in respect thereof) referred to


                                       18

<PAGE>


herein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities or expenses (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Underwriters on the other from the offering of the Common Stock.
If, however, the allocation provided by the immediately preceding sentence is
not permitted by applicable law, then each indemnifying party shall contribute
to such amount paid or payable by such indemnified party in such proportion as
is appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses (or actions in respect thereof), as
well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Underwriters on the other shall
be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus. The relative
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Underwriters and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable
if contribution were determined by pro rata allocation (even if the Underwriters
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to above. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages, liabilities or expenses (or actions in respect thereof)
referred to above shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating,
defending, settling or compromising any such claim. Notwithstanding the
provisions of this subsection (d), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the shares of the Common Stock underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. The Underwriters'
obligations to contribute are several in proportion to their respective
underwriting obligations and not joint. 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.

                  7. SURVIVAL OF INDEMNITIES, REPRESENTATIONS, WARRANTIES, ETC.
The respective indemnities, covenants, agreements, representations, warranties
and other statements of the Company, and the several Underwriters, as set forth
in this Agreement or made by them respectively, pursuant to this Agreement,
shall remain in full force and effect, regardless of any investigation made by
or on behalf of any Underwriter, the Company or any of its officers or directors
or any controlling person, and shall survive delivery of and payment for the
Common Stock.

                  8. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The respective
obligations of the


                                       19

<PAGE>

several Underwriters hereunder shall be subject to the accuracy, at and (except
as otherwise stated herein) as of the date hereof and at and as of each of the
Closing Dates, of the representations and warranties made herein by the Company,
to compliance at and as of each of the Closing Dates by the Company with its

satisfied at or prior to each of the Closing Dates, and to the following
additional conditions:

no stop order suspending the effectiveness thereof shall have been issued and no
proceedings for that purpose shall have been initiated or, to the knowledge of

any request for additional information on the part of the Commission (to be
included in the Registration Statement or the Prospectus or otherwise) shall
have been complied with to the reasonable satisfaction of the Representative.
Any filings of the Prospectus, or any supplement thereto, required pursuant to
Rule 424(b) or Rule 434 of the Rules and Regulations, shall have been made in
the manner and within the time period required by Rule 424(b) and Rule 434 of
the Rules and Regulations, as the case may be.

                  (b) The Representatives shall have been satisfied that there
shall not have occurred any change, on a consolidated basis, prior to each of
the Closing Dates in the condition (financial or otherwise), properties,
business, management, prospects, net worth or results of operations of the
Company and its subsidiaries considered as a whole, or any change in the capital
stock, short-term or long-term debt of the Company and its subsidiaries
considered as a whole, such that (i) the Registration Statement or the
Prospectus, or any amendment or supplement thereto, contains an untrue statement
of fact which, in the opinion of the Representatives, is material, or omits to
state a fact which, in the opinion of the Representatives, is required to be
stated therein or is necessary to make the statements therein not misleading, or
(ii) it is unpracticable in the reasonable judgment of the Representatives to
proceed with the public offering or purchase the Common Stock as contemplated
hereby.

                  (c) The Representatives shall be satisfied that no legal or
governmental action, suit or proceeding affecting the Company which is material
and adverse to the Company or which affects or may affect the Company's ability
to perform their respective obligations under this Agreement shall have been
instituted or threatened and there shall have occurred no material adverse
development in any existing such action, suit or proceeding.

                  (d) At the time of execution of this Agreement, the
Representatives shall have received from PricewaterhouseCoopers LLP, independent
certified public accountants, a letter, dated the date hereof, in form and

Dates, the statements made in the letter furnished by such accountants pursuant
to paragraph (d) of this Section 8.

effectiveness of the Registration Statement or at such earlier time after the
Registration Statement becomes effective as the Representatives may determine on
and by notice to the Company or by release of any of the Common Stock for sale

newspaper advertisement relating to the Common Stock or upon the release by you
of telegrams (i) advising the Underwriters that the shares of Common Stock are

                  10. TERMINATION. This Agreement (except for the provisions of
Section 5) may be terminated by the Company at any time before it becomes
effective in accordance with Section 9 by notice to the Representatives and may
be terminated by the Representatives at any time before it becomes effective in
accordance with Section 9 by notice to the Company. In the event of any
termination of this Agreement under this or any other provision of this
Agreement, there shall be no liability of any party to this Agreement to any
other party, other than as provided in Sections 5, 6 and 11 and other than as
provided in Section 12 as to the liability of defaulting Underwriters.

                  This Agreement may be terminated after it becomes effective by

an outbreak or escalation of hostilities between the United States and any
foreign power or of any other insurrection or armed conflict involving the
United States or (B) any change in financial markets or any calamity or crisis
which, in the judgment of the Representatives, makes it impractical or
inadvisable to offer or sell the Common Stock on the terms contemplated by the
Prospectus; (iv) if there shall have been any development or prospective
development involving particularly the business or properties or securities of
the Company or any of its subsidiaries or the transactions contemplated by this
Agreement, which, in the judgment of the Representatives, makes it impracticable
or inadvisable to offer or deliver the Common Stock on the terms contemplated by
the Prospectus; (v) if there shall be any litigation or proceeding, pending or
threatened, which, in the judgment of the Representatives, makes it
impracticable or inadvisable to offer or deliver the Common Stock on the terms
contemplated by the Prospectus; or (vi) if there shall have occurred any of the
events specified in the immediately preceding clauses (i) - (v) together with
any other such event that makes it, in the judgment of the Representatives,
impractical or inadvisable to offer or deliver the Common Stock on the terms
contemplated by the Prospectus.

                  11. REIMBURSEMENT OF UNDERWRITERS. Notwithstanding any other
provisions hereof, if this Agreement shall not become effective by reason of any
election of the Company pursuant to the first paragraph of Section 10 or shall
be terminated by the Representatives under Section 8 or Section 10, the Company
will bear and pay the expenses specified in Section 5 hereof and, in addition to
the obligations pursuant to Section 6 hereof, the Company will reimburse the
reasonable out-of-pocket expenses of the several Underwriters (including
reasonable fees and disbursements of counsel for the Underwriters) incurred in
connection with this Agreement and the proposed purchase of the Common Stock,
and promptly upon demand the Company will pay such amounts to you as
Representatives.

                  12. SUBSTITUTION OF UNDERWRITERS. If any Underwriter or
Underwriters shall default in its or their obligations to purchase shares of
Stock hereunder and the aggregate number of shares which such defaulting
Underwriter or Underwriters agreed but failed to purchase does not exceed ten
percent (10%) of the total number of shares underwritten, the other Underwriters
shall be obligated severally, in proportion to their respective commitments
hereunder, to purchase the shares which such defaulting Underwriter or
Underwriters agreed but failed to purchase. If any Underwriter or Underwriters
shall so default and the aggregate number of shares with respect to which such
default or defaults occur is more than ten percent (10%) of the total number of
shares underwritten and arrangements satisfactory to the Representatives and the
Company for the purchase of such shares by other persons are not made within
forty-eight (48) hours after such default, this Agreement shall terminate.

                  If the remaining Underwriters or substituted Underwriters are
required hereby or agree to take up all or part of the shares of Stock of a
defaulting Underwriter or Underwriters as provided in this Section 12, (i) the
Company shall have the right to postpone the Closing Dates


                                       23

<PAGE>


for a period of not more than five (5) full business days in order that the
Company may effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees promptly to file any amendments to the
Registration Statement or supplements to the Prospectus which may thereby be
made necessary, and (ii) the respective numbers of shares to be purchased by the
remaining Underwriters or substituted Underwriters shall be taken as the basis
of their underwriting obligation for all purposes of this Agreement. Nothing
herein contained shall relieve any defaulting Underwriter of its liability to
the Company or the other Underwriters for damages occasioned by its default
hereunder. Any termination of this Agreement pursuant to this Section 12 shall
be without liability on the part of any non-defaulting Underwriter or the
Company, except for expenses to be paid or reimbursed pursuant to Section 5 and
except for the provisions of Section 6.

                  13. NOTICES. All communications hereunder shall be in writing

SG COWEN SECURITIES CORPORATION,

  As Representatives of the several Underwriters named in Schedule A
c/o SG Cowen
Financial Square

                            Re: HEALTHGATE DATA CORP.
                        3,750,000 Shares of Common Stock

Dear Sirs:

                  We have acted as counsel for HealthGate Data Corp., a Delaware
corporation (the "Company"), in connection with the sale by the Company and
purchase of 3,750,000 shares of Common Stock, par value $0.01 per share, of the
Company (the "Shares") by the several Underwriters listed in Schedule A to the
Underwriting Agreement, dated June ___, 1999, among the Company and SG Cowen,
Volpe Brown Whelan and Company, LLC and Warburg Dillon Read LLC, as
Representatives of the several Underwriters named therein (the "Underwriting
Agreement"). This opinion is being furnished pursuant to Section 8(f) of the
Underwriting Agreement. All defined terms not defined herein shall have the
meanings ascribed to them in the Underwriting Agreement.

                  We have examined and are familiar with originals or copies,
certified or otherwise authenticated to our satisfaction, of documents,
corporate records, legal materials and other writings which we consider relevant
for purposes of this opinion.

                  We are of the opinion that:

                  1. The Company and each of its subsidiaries have been duly
incorporated and are validly existing as corporations in good standing under the
laws of their respective jurisdictions of incorporation, are duly qualified to
do business and are in good standing as foreign corporations in each
jurisdiction in which their respective ownership or lease of property or the
conduct of their respective businesses requires such qualification, except where
the failure to not qualify would not have a material adverse effect on the
Company and its subsidiaries taken


<PAGE>


as a whole, and have all power and authority necessary to own or hold their
respective properties and conduct the businesses in which they are engaged.

                  2. The Company has an authorized capitalization as set forth
in the Prospectus, and all of the issued shares of capital stock of the Company
have been duly and validly authorized and issued, are fully paid and
non-assessable and all of the Shares to be issued and sold by the Company to the
Underwriters pursuant to the Underwriting Agreement have been duly and validly
authorized and, when issued and delivered against payment therefor as provided
for in the Underwriting Agreement, shall be duly and validly issued, fully paid
and non-assessable; and all of the issued shares of capital stock of each
subsidiary of the Company have been duly and validly authorized and issued and
are fully paid, non-assessable and are owned directly or indirectly by the
Company, free and clear of all liens, encumbrances, equities or claims.

                  3. There are no preemptive or other rights to subscribe for or
to purchase, nor any restriction upon the voting or transfer of, any of the
Shares pursuant to the Company's Certificate of Incorporation or By-Laws or any
agreement or other instrument.

                  4. Except as described in the Prospectus, there are no legal
or governmental proceedings pending to which the Company or any of its
subsidiaries is a party or of which any property or assets of the Company or any
of its Subsidiaries is the subject which, if determined adversely to the Company
or any of its subsidiaries, could have a material adverse effect on the Company
and its subsidiaries; and, to the best of our knowledge, no such proceedings are
threatened or contemplated by governmental authorities or other third parties.

                  5. The Company and each of its subsidiaries own or possess all
patents, trademarks, trademark registrations, service marks, service mark
registrations, trade names, copyrights, licenses, inventions, trade secrets and
rights described in the Prospectus as being owned by them or any of them, and,
except as described in the Prospectus, we are not aware of any claim to the
contrary or any challenge by any other person to the rights of the Company or
any of its subsidiaries with respect to the foregoing.

                  6. The Company and each of its subsidiaries have, and the
Company and each of its subsidiaries as of the Closing Dates will have, good and
marketable title in fee simple to all real property and good and marketable
title to all personal property owned or proposed to be owned by them which is
material to the business of the Company or any of its subsidiaries, in each case
free and clear of all liens, encumbrances and defects, except such as are
described in the Prospectus or such as would not have a material adverse effect
on the Company and its subsidiaries taken as a whole; and any real property and
buildings held under lease by the Company and its subsidiaries or proposed to be
held after giving effect to the transactions described in the Prospectus are, or
will be as of the Closing Dates, held by them under valid, subsisting and
enforceable leases with such exceptions as would not have a material adverse
effect on the Company and its subsidiaries considered as a whole.


                                       I-2

<PAGE>


                  7. The Company has full corporate power and authority to enter
into the Underwriting Agreement and to perform its obligations thereunder
(including to issue, sell and deliver the Shares), and the Underwriting
Agreement has been duly and validly authorized, executed and delivered by the
Company and is a valid and binding obligation of the Company, enforceable
against the Company in accordance with its terms, except to the extent that
rights to indemnification and contribution thereunder may be limited by federal
or state securities laws or the public policy underlying such laws.

                  8. The execution, delivery and performance of the Underwriting
Agreement and the consummation of the transactions therein contemplated will not
result in a breach or violation of any of the terms or provisions of or
constitute a default under any material indenture, mortgage, deed of trust, note
agreement or other agreement or instrument to which the Company or any of its
subsidiaries is a party or by which any of them or any of their properties is or
may be bound, the Certificate of Incorporation, Bylaws or other organizational
documents of the Company or any of its subsidiaries, or any law, order, rule or
regulation of any court or governmental agency or body having jurisdiction over
the Company or any of its subsidiaries or any of their properties or result in
the creation of a lien.

                  9. No consent, approval, authorization or order of any court
or governmental agency or body is required for the consummation by the Company
of the transactions contemplated by the Underwriting Agreement, except such as
may be required by the National Association of Securities Dealers, Inc. (the
"NASD") or under the Securities Act or the securities or "Blue Sky" laws of any
jurisdiction in connection with the purchase and distribution of the Shares by
the Underwriters.

                  10. To the best of our knowledge after reasonable
investigation, the Company and each of its subsidiaries are in compliance with,
and conduct their businesses in conformity with, all applicable federal, state,
local and foreign laws, rules and regulations, including, but not limited to,
those of any governmental agency, court or tribunal; to the best of our
knowledge, no prospective change in any of such federal, state, local or foreign
laws, rules or regulations has been adopted which, when made effective, would
have a material adverse effect on the operations of the Company and its
subsidiaries.

                  11. The Registration Statement was declared effective under
the Securities Act as of __________, 1999, the Prospectus was filed with the
Commission pursuant to Rule 424(b) of the Rules and Regulations on __________,
1999 and no stop order suspending the effectiveness of the Registration
Statement has been issued and no proceeding for that purpose is pending or, to
the best of our knowledge, threatened by the Commission.

                  12. The Registration Statement and the Prospectus and any
amendments or supplements thereto comply as to form in all respects with the
requirements of the Securities Act and the Rules and Regulations and the
documents incorporated by reference in the Prospectus, when they became
effective or were filed with the Commission, as the case may be, complied as to
form in all respects with the requirements of the Securities Act or the Exchange
Act, as applicable, and the Rules and Regulations; and any amendment or
supplement to any such


                                       I-3

<PAGE>


incorporated document, when they became effective or were filed with the
Commission, as the case may be, complied as to form in all respects with the
requirements of the Securities Act or the Exchange Act, as applicable, and the
Rules and Regulations.

                  13. To the best of our knowledge, there are no contracts or
other documents which are required by the Securities Act or by the Rules and
Regulations to be described in the Prospectus or filed as exhibits to the
Registration Statement which have not been described in the Prospectus or filed
as exhibits to the Registration Statement or incorporated therein by reference
as permitted by the Rules and Regulations.

                  14. Other than as described in the Prospectus, there are no
contracts, agreements or understandings between the Company and any person
granting such person the right (other than rights which have been waived or
satisfied) to require the Company to file a registration statement under the
Securities Act with respect to any securities of the Company owned or to be
owned by such person or to require the Company to include such securities in the
securities registered pursuant to this Registration Statement or in any
securities being registered pursuant to any other registration statement filed
by the Company under the Securities Act.

                  15. The descriptions in the Registration Statement and
Prospectus of statutes, rules, regulations, legal or governmental proceedings,
contracts and other documents are accurate and such descriptions fairly present
the information required to be disclosed; and to the best of our knowledge,
there are no legal or governmental proceedings, statutes, rules or regulations,
or any contracts or documents of a character required to be described in the
Registration Statement or Prospectus or to be filed as exhibits to the
Registration Statement which are not described and filed as required.

                  16. The statements under the captions "Risk Factors", and
"Government Regulation", to the extent they reflect matters of federal law
arising under the laws of the United States or legal conclusions relating to
such law, accurately summarize and fairly present the legal and regulatory
matters described therein.

                  17. The Company and each of its subsidiaries are not, nor will
they be immediately after receiving the proceeds from the sale of the Shares, an
"investment company" or an entity "controlled" by an "investment company" as
such terms are defined in the Investment Company Act of 1940, as amended.

                  The foregoing opinion is limited to matters governed by the
Federal laws of the United States of America, the general corporate law of the
State of Delaware and the laws of the Commonwealth of Massachusetts.

                  We have acted as counsel to the Company on a regular basis,
have acted as counsel to the Company in connection with previous financing
transactions and have acted as counsel to the Company in connection with the
preparation and filing of the Registration Statement and the Prospectus. The
Company has from time to time engaged other counsel for certain matters.
Although we have not undertaken to determine independently, and do not


                                       I-4

<PAGE>


assume any responsibility for, the accuracy, completeness or fairness of the
statements in the Registration Statement except as set forth in paragraph 15 of
our opinion, based on the foregoing, no facts have come to our attention which
lead us to believe that (i) the Registration Statement or any amendment thereto,
as of the Effective Date, contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein not misleading, or that the Prospectus
contains any untrue statement of a material fact or omits to state a material
fact Required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading or (ii) any document incorporated by reference in the Prospectus or
any amendment or supplement to any such incorporated document made by the
Company, when they became effective or were filed with the Commission, as the
case may be, contained, in the case of a registration statement which became
effective under the Securities Act, any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein not misleading, or, in the case of
documents filed under the Exchange Act with the Commission, contained any untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading (it being understood that we express no opinion
with respect to the financial statements and the notes thereto and the schedules
and other financial and statistical data included in the Registration Statement
or the Prospectus).

                  Our opinion is subject to the following qualifications:

                  (a) Insofar as this opinion relates to factual matters, we
have relied upon the certificates and documents described herein and upon
discussions with officers of the Company. Although nothing has come to our
attention leading us to question, or giving us reasonable grounds to question,
the accuracy of such certificates, documents and discussions, we have not made
any independent review or investigation.

                  (b) We have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified or photostatic
copies, the accuracy and completeness of all records made available to us by the
Company and the enforceability of the Underwriting Agreement against the
Underwriters to the extent such enforceability is necessary to render our
opinion.

                  (c) The enforceability of any provisions in the Underwriting
Agreement may be subject to and affected by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the rights of creditors
generally, and the remedies of specific performance, injunction and other forms
of equitable relief may be subject to certain tests of equity jurisdiction,
equitable defenses and judicial discretion.

                  (d) In connection with opinions expressed herein as being made
"to our knowledge", our examination has been limited to discussions with the
officers of the Company and our knowledge of the affairs of the Company as their
counsel, and we have made no independent investigations as to the accuracy or
completeness of any representations, warranties,


                                       I-5

<PAGE>


data or other information, written or oral, made or furnished by the Company to
us or to you.

                  This opinion is rendered only to you and solely for your
benefit in connection with the transactions contemplated by the Underwriting
Agreement and may not be relied upon by any other person for any purpose without
the prior written consent of the undersigned. We disclaim any obligation to
advise you of any developments in matters covered by this opinion that occur
after the date of this opinion.

                  Our opinions herein are limited to the laws of The
Commonwealth of Massachusetts and the general corporate law of the State of
Delaware and the Federal laws of the United States of America, and we express no
opinion as to any matter governed by the laws of any other jurisdiction.

                                Very truly yours,



                                RICH, MAY, BILODEAU & FLAHERTY, P.C.

HealthGate Data Corp.

Gentlemen and Ladies:

         We have acted as counsel to HealthGate Data Corp., a Delaware
corporation (the "Company"), in connection with (a) the preparation of the
Company's Registration Statement on Form S-1, File No. 333-76899 (the
"Registration Statement"), initially filed on April 23, 1999 with the
Securities and Exchange Commission under the Securities Act of 1933, for the
registration of an aggregate of 4,312,500 shares of the Company's common
stock, par value $.01 per share (the "Shares"), and (b) the Underwriting
Agreement (the "Agreement"), to be entered into between the Company and SG
Cowen Securities Corporation, Volpe Brown Whelan & Company and Warburg Dillon
Read, as Representatives of the Underwriters, the form of which is attached
as Exhibit 1.1 to the Registration Statement.

         Of the 4,312,500 Shares included in the Registration Statement,
3,750,000 Shares (the "Firm Shares") will be issued and sold by the Company
to the several Underwriters to be named in Schedule A to the Agreement (the
"Underwriters"); and, solely for the purpose of covering over-allotments, the
Company proposes to sell to the Underwriters up to an additional 562,500
shares (the "Additional Shares").

         We have examined the originals, or certified, conformed or reproduction
copies, of all such records, agreements, instruments and documents as we have
deemed relevant or necessary as the basis for the opinions hereinafter
expressed. In all such examinations, we have assumed the genuineness of all
signatures on original or certified copies and the conformity to original or
certified copies of all copies submitted to us as conformed or reproduction
copies. As to various questions of fact relevant to our opinion, we have relied
upon statements or certificates of public officials, officers or representatives
of the Company and others.

         Based upon the foregoing, we are of the opinion that the Firm Shares
and the Additional Shares to be sold by the Company to the Underwriters, when
issued, delivered and paid for in accordance with the terms of the Agreement,
will be validly issued, fully paid and non-assessable.

         We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the Prospectus forming a part of the Registration Statement.


                                      Very truly yours,

                                      /s/ Rich, May, Bilodeau & Flaherty, P.C.

      Agreement:

      The Publishers grant HealthGate an exclusive right to carry out the

3.    Duration

      3.1.  This Agreement shall commence on 1 January 1998. The initial term of
            the Services, unless terminated as set out herein, shall continue up
            to and including 28 February 2000 ("the Initial Term").

5.    Milestones and Deliverables

      5.1.  If HealthGate fails to complete the System development by the System
            Completion Date, unless such failure results from the Publishers'
            default in performing its obligations under this Agreement or from
            an extension of time agreed in writing, the Publishers may in their
            discretion notify HealthGate accordingly, and if such failure is not
            remedied within 28 calendar days, HealthGate, recognising the loss
            caused to the Publishers, will on demand from the Publishers pay to
            the Publishers a sum calculated at the rate of 1% of the value of
            the contract in respect of every 28 days which elapse from the
            System Completion Date to the actual date of completion of the
            System. Such sums of money will be paid by HealthGate to the
            Publishers not as a penalty but as and for the ascertained and
            liquidated damages owing and payable by HealthGate to the Publishers
            by reason of such failure to meet the System Completion Date.

      5.2.  If HealthGate fails to complete the System by the end of the tenth
            week after the System Completion Date then the Publishers (unless
            such failure demonstrably results from the Publishers' default in
            the performance of its obligations under this Agreement) will be
            entitled without prejudice to any other rights or remedies they may
            have under this Agreement or at law or in equity to terminate this
            Agreement immediately by written notice.

      5.3.  If any delay in meeting the System Completion Date is in any way due
            to the Publishers' fault, HealthGate will nevertheless, if the
            Publishers so requests, continue with the work on the Project with a
            view to completing it as soon as reasonably possible in the
            circumstances, and the Development Timetable will be adjusted
            accordingly.

6.    Project Management

      6.1.  HealthGate and the Publishers shall each designate the name,
            address, telephone number, fax number, and e-mail address of a
            Project Manager and a Deputy Project Manager. The Project Managers
            shall be responsible for arranging all meetings, visits, and
            consultations between the parties, and for the transmission and
            receipt of technical information between the parties. The parties'
            initial Project Manager and Deputy Project Manager is set forth on
            the Third Schedule hereto.

      6.2.  If HealthGate has reason to believe that any estimate of any time is
            likely to be exceeded or that it is likely that the Development
            Timetable will not be complied with, HealthGate will immediately
            inform the Publishers' Project Manager by written notice.

      Content in loadable electronic format to HealthGate as specified in the
      Specification. HealthGate shall remotely load the Content into a staging
      area.

8.    Procurement of Hardware

      HealthGate shall maintain the Site on HealthGate's web server and/or other
      servers through the term of this Agreement insofar as it relates to the
      Services. HealthGate shall acquire and maintain all necessary equipment
      and hardware (collectively the "Hardware") for Site. The Hardware shall be
      capable of storing the Content, including future issues of the Journals
      within the Content. HealthGate shall replace and upgrade such Hardware to
      satisfy the requirements of the Specification. The Hardware for the Site
      shall include redundancy so that the Site may remain operational despite
      an equipment failure. The Hardware shall be located at HealthGate's
      computer facilities in Malden, Massachusetts. The Hardware may be
      relocated only with Publishers' written consent, which consent shall not
      be unreasonably withheld. HealthGate, at its cost and expense, shall
      maintain adequate access via telecommunications to the Site at service
      levels that shall be maintained at the same extent as HealthGate provides
      to its own users.

9.    Testing, Acceptance and Delivery

      9.1.  Upon completion of the Development Work HealthGate and the
            Publishers shall run acceptance tests to assure compliance with the
            Specification. Load testing will be conducted at HealthGate. Such
            period of acceptance testing shall not exceed 2 weeks from date of
            delivery for testing.

      9.2.  Upon passing the acceptance tests, the System shall be deemed
            Accepted

      9.3.  Upon Acceptance as provided in Clause 9.2 HealthGate shall deliver
            into escrow the source code, source listings and information for the
            Proprietary Software included in the System in accordance with the
            terms of the Escrow Agreement.

      9.4.  In the event that the system fails to pass any of the prescribed
            acceptance tests or fails to satisfy the Publishers' requirements,
            the Publishers shall afford HealthGate the opportunity of
            rectifying, replacing and retesting the System. In the event that
            the System or any part thereof again fails to be accepted, such
            acceptance shall not be unreasonably withheld, or to satisfy the
            Publishers' requirements of which the Publishers shall be the sole
            judge, the Publishers shall (as time is of the essence of this
            Agreement) be entitled, in addition to any other rights it may have
            under this Agreement or in law, to have HealthGate remove the
            Content from the System (in whole or in part as the Publishers so

                                       6


<PAGE>

            instructs) and HealthGate shall be liable to refund forthwith any
            moneys paid by the Publishers for such rejected System or part
            thereof. Notwithstanding the foregoing, upon acceptance of System
            launch, as noted in Clause 19.2.4, HealthGate shall be entitled to
            retain all monies paid by Publishers to this point.

            In such circumstances HealthGate shall be entitled to retain the
            first $250,000 paid by the Publishers to develop the Specification.

10.   Licence

      10.1. Proprietary Software

            HealthGate hereby grants to the Publishers a non-exclusive
            non-transferable licence to use the Proprietary Software for the
            purposes of this Agreement

            Save in relation to the Publishers' logos, trademarks, and content,
            HealthGate may use and/or licence the Proprietary Software for
            itself or for others without any compensation or liability to the
            Publishers.

            All Proprietary Software and Source Code remain the property of
            HealthGate. Publishers may not use either Proprietary Software or
            Source Code held in escrow to develop a product that competes with
            those services offered by HealthGate. HealthGate, in its sole
            discretion, retains the right to determine if Publishers are
            utilizing either the Proprietary Software or Source Code in
            violation of this Agreement.

      10.2. Option for Licence

            10.2.1. On termination of the provision of the Services by
                    HealthGate to the Publishers for whatever reason, HealthGate
                    shall at the Publishers' option:

                          (i) grant to the Publishers a non-exclusive
                    non-transferable licence to use the Proprietary Software for
                    the purposes of using, developing, enhancing and maintaining
                    the Site and carrying out any or all of the activities
                    previously carried out by HealthGate or on its behalf under
                    this Agreement

                          (ii) exercise best endeavours to grant to the
                    Publishers a non-exclusive non-transferable licence to use
                    the Third Party Software for the Site when and to the extent
                    requested by the Publishers.

            10.2.2. The annual fee for the licence in Clause 10.2.1 for the
                    Software, to include the Proprietary Software and the Third
                    Party Software, shall be $150,000 per annum, including
                    standard upgrades and maintenance, provided that if
                    HealthGate is not able to grant a licence of the Third Party
                    Software, then the Publishers shall be at liberty to licence
                    the Third Party Software from its owners and/or licensors
                    direct, and/or to

                                       7

<PAGE>

                    license alternative software, and shall deduct the fees for
                    such licences from the $150,000 per annum for the Software.

            10.2.3. The Publishers shall have the right to terminate the licence
                    referred to in Clause 10.2.1 by giving three months' notice
                    in writing to HealthGate.

      12.2. The Service Levels will be subject to review at any time by
            agreement between the Project Managers and in any event will be
            formally reviewed every 12 months during the term of this Agreement.

      12.3. HealthGate will provide usage statistics relating to the Services as
            described in the specification on a monthly basis, or such other

            Services.

13.   Permitted Users, Pricing and Subscription Information

      13.1. The Publishers shall have sole authority concerning determining

            to the Publishers' subscribers and other third party users for
            access to the Publishers' Content on the Site. The Site shall be
            designed to permit automated loading and maintenance of subscription
            data from the Publishers' fulfilment systems. The Specification
            details the procedures for loading such subscription information
            (including both bulk entry and single entry information) and timing
            for access to the Site for users included on such updated
            subscription data.

            access the Site and to authorize access to users in terms within the

            any event the service fee may not exceed 30% of the Article Fee for
            the particular article, or $US 4, whichever is the higher. Within 60
            days of the end of each calendar month, HealthGate shall forward to
            Publishers the net Article Fees actually collected (exclusive of
            HealthGate's service fee).

            individual articles and other items, on terms to be agreed between
            the Publishers and such third party intermediaries. Neither the
            Publishers nor the third party intermediaries shall be required to
            pay a service fee or any other additional fee for this service, nor
            shall HealthGate be permitted to collect a service fee, its
            remuneration being as provided in Clause 19 and in Schedule 2 (Use
            Fees).

16.   Links

      The Site shall support and include in-bound links, as may be mutually
      agreed upon, to the Publishers' Content (including citations and
      references within articles), from bibliographic databases, including
      HealthGate, PubMed, ISI's Web of Science, and other sites, and as required
      by the Publishers from time to time. HealthGate shall not be responsible
      for setting up links from sites which it does not host. The Site shall

            Services by notice in writing to HealthGate to be given on or before
            30 September 1999. If the Publishers exercise their right to renew,
            the term of the Services shall be extended by one further year, up
            to and including 28 February 2001. The Use Fees shall remain the

            exceed $7000 for additional journals, $2000 maintenance fee on
            existing journals and $2000 per Gigabyte.

      17.2  If the Publishers exercise their right of renewal under Clause 17.1,
            then the Publishers shall have a further right of renewal for each
            of the subsequent three years, provided that the right to renew
            shall be conditional upon the Publishers having exercised their
            right in the previous year, and giving notice on or before the 30
            September before the renewal is to take effect.

18.   Assistance upon Termination

      Publishers for any reason:

            mutually satisfactory license to the Publishers or, at the
            Publishers' option, to a replacement contractor. The period of

            assumption of the Services by the Publishers or, at the Publishers'
            option, by a replacement contractor;

      18.3. If the Publishers so require, HealthGate will use its best
            endeavours to procure the transfer at the Publishers' expense, to
            the Publishers or to a third party nominated by the Publishers at
            the Publishers' sole discretion, of any Third Party Software
            licences HealthGate may have obtained in its own name in order to
            provide the Services and used for that purpose exclusively; and

      18.4. HealthGate will be obliged to satisfy the Publishers that it has
            erased the Publishers Content and all copies, and that it has no
            ability to reproduce the Publishers Content in any way.

20.   Advertising

            upon from time to time and detailed in the Specification. The rate
            structure for advertising shall be mutually agreed upon.

      20.2. All advertising is subject to review and approval by the Publishers
            and the Publishers reserve the right to refuse any proposed

            party shall receive 30% of all advertising sales for advertising
            sales originated by the other party (provided, in the event that
            advertising is sold at rates less than fair market rates such 30%
            figure shall be equitably increased to reflect the fair market value
            of the advertising. Said fair market rates shall be determined by
            mutual agreement of both parties). No deduction shall be made for
            commissions payable to sales representatives or employees of any
            party.

Blackwell/Munksgaard publications and services to existing readers online, as
well as develop an audience of new Internet users. Since the focus of this
project is to expand readership and usage, the design of this project will be
driven by user needs and interests.

The following scenarios illustrate how to optimally meet the needs and offer the
widest selection of services to Blackwell/Munksgaard users through a series of
chronological steps and options. A user is defined as any party (including
individuals or other systems) that will interface with the Blackwell/Munksgaard
Journal Publishing system.

      For any but the most casual browser, general registration is encouraged,
      and outlined below.

      1.    Registration procedure: If a non-registered user would like to
            access certain areas or services, there will be a link provided to
            the registration area.

            Once the user has entered the registration area, s/he will be asked
            to provide full name, email address, and postal address. After this
            information has been entered, the user will be provided with a
            dialog box to enter a self-selected user name and password.

      2.    Creating user name: The user name is checked for uniqueness against
            all user names, then added to the database. If the name has already
            been registered, the user will be provided with three suggested
            names, or the option to create another user name of their own
            choice.

      3.    Confirmation of registration: Once a unique user name and password
            have been assigned, the user may choose to continue the purchase
            process by linking to pages that will enable him/her to enter credit
            card information (see "Credit Card Subscription Registration"
            below). If no purchase is desired at this time, the user will end
            the registration process at this point S/he will see a page that
            confirms their registration. Shortly afterwards, the user will also
            receive an email acknowledging their registration, and providing
            instructions on what to do if they forget their user name and
            password. This will also serve to ensure that the user's email
            address as entered in the registration form is correct.

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

Credit Card Subscription Registration

      Users will now be able to order subscriptions to Blackwell/Munksgaard
      journals and publications online via a simple registration and secure
      payment process. In this scenario, the user chooses to pay with a credit
      card.

      1.    Registration: When the user enters the registration area, s/he will
            be asked to provide their user name and password. (See "General
            Registration" above).

      2.    Tracking marketing efforts: A feature to track the efficacy of
            marketing campaigns may also be incorporated. In addition to
            entering the above subscriber information, the user will also be
            asked to provide information pertaining to offer codes, or other
            identifying characteristics of marketing offers.

      3.    Separating society memberships: Users are asked if they are a member
            of a society participating in the online journals. If they select a
            society, their registration information will be checked with an
            updated automated listing of existing society members. Since a
            society member is entitled to pre-defined journal subscriptions
            under a separate agreement, this is done to ensure that a society
            member is not charged. If the registering user is determined to be a
            society member, follow the "Society Member Registration" scenario
            instead.

      4.    Selecting a subscription plan: After entering the registration
            information, the user will be prompted to select a subscription
            plan.

      5.    Charging subscriptions: Once the subscription plan has been
            selected, the user will then be shown a page that provides a secure
            connection for credit card information. The user will be asked to
            give the credit card number, type (VISA, MasterCard, AMEX,
            Discover), and expiration date.

      6.    Transaction receipt: The credit card is then validated and the user
            is shown the cost that has been charged to the credit card. A
            receipt is displayed on the screen, as well as emailed to the user.

      7.    Thanks/Email notification of future publications: After the
            registration process is completed, the user will see a page thanking
            them for their subscription order. As an added feature, new users
            will be offered the option of having the table of contents of each
            new issue emailed to them upon publication.

      8.    Next destination: When the above information is provided, the user
            will then be given access to the cover page of the journal that has
            just been ordered.

Society Member / Institutional Subscriber Self Registration

      If a user is determined to be a Society member or a paid subscriber not
      know to the system (pre-subscribed by Blackwell/Munksgaard), the following
      scenario applies:

      1.    Access from marketing efforts: Society membership benefits include
            subscriptions to pre-defined print journals. In accordance with
            marketing efforts, inserts promoting online journal registration and
            the URL for the Blackwell/Munksgaard site will be provided in these
            journals. Members may also find out about online service via other
            marketing efforts, such as newsletters, leaflets, direct mail or
            other web sites.

      2.    Registration info: Once the user accesses the site, he/she will be
            provided with a form asking for basic registration information (see
            "Credit Card Subscription Registration," steps 1-7).

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

      3.    Membership options: If the name has been matched and verified online
            as a Society member, the user is presented with a listing of
            publications and journals, etc. which they may access with existing
            membership privileges.

            If the user is not verified as a current Society member, the user
            will be asked to provide standard registration information (see
            "Credit Card Subscription Registration").

            In addition to the publication listings, users will be given one of
            three options as defined by the publisher to receive these
            subscriptions:

            a. Exclusive online access

            b. Print subscription and optional online access

            c. Full access via both print subscription and online

      4.    Content for purchase: Once users have selected their subscription
            method, they will be shown additional content available for
            purchase.

      5.    Creating identity code for user: When content for purchase has been
            selected by the user, s/he will see a form that enables them to
            create a user name and password. Once the information has been
            entered, another dialog box will prompt them to confirm the
            password.

      6.    Assuring uniqueness of code: The user name is checked for uniqueness
            against all user names, and added to the list. If the user name has
            already been registered, they will be provided with three suggested
            names, or the option to create another user name of their own
            choice.

      7.    Purchasing additional content: If the user chooses to purchase any
            of the additional content, the purchase will be charged to the
            credit card information previously provided. The credit card is
            validated and charged. If the credit card is declined, the user is
            prompted to try again.

      8.    Transaction receipt: Once the credit card has been validated, the
            page shows the cost that has been charged to the credit card.
            Receipt is presented on the screen, as well as emailed to the user.

      9.    Final step of purchasing process: As the final step in the
            purchasing process, the user will see a page that thanks them for
            their order, and shows a listing of all content purchased in the
            last transaction.

            After purchasing process has been completed, the user will then be
            given access to their selected content. A confirmation email will be
            sent welcoming the user to our service.

Purchase Order or Deposit Account for Institutional Subscribers

      For those institutions that wish to order subscriptions to
      Blackwell/Munksgaard journals, publications, and single full-text articles
      on a consistent basis, an open purchase order or deposit account may be
      established. The following scenario outlines how a customer would have
      access via this method.

      1.    Initial set-up: The customer will make the initial contact to
            Blackwell/Munksgaard to set up the account. Open purchase orders and
            deposit accounts may be established through either
            Blackwell/Munksgaard or HealthGate.

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

      2.    Access code: After the account has been established, users will then
            be given a special access code to access the Site. When registering
            the user will be able to use the access code instead of providing us
            with credit card information (Access to publications via IP address
            verification is an option for institutional accounts).

      3.    Registration: When the user completes registration the same way as a
            normal customer, except that they enter the access code rather than
            provide billing information. Any charges or purchases will be
            applied to their account.

      4.    Account expiration: If the account expires, or reaches the monetary
            cap assigned, the user will be shown a page that prompts them to
            contact Blackwell/Munksgaard to renew the account. This page will
            also provide the option to continue and have purchases applied to a
            credit card. A report will be available warning Blackwell/Munksgaard
            of accounts that are close to expiring.

Transaction Registration /Single Document Purchase by non registered user

      This scenario outlines the way in which a user would be able to purchase a
      single article (document) while browsing the abstract of the article.

      1.    Promoting full text articles: Abstracts are available to all users
            free of charge; registration is not required. However, if the user
            would like to buy the full text of any given article, pricing
            information for the article will be listed at the end of the
            abstract, with a link to purchase the article.

      2.    Purchasing full text -- registered users: After selecting the link
            to purchase the article, the user is given the option to log in,
            using the previously assigned registration user name and password.
            After logging in, a page showing full text articles and journal
            subscriptions for purchase will be provided. The user will make
            his/her selections, and the credit card information page will
            appear. (Go to step #5)

      3.    Purchasing full text -- new users: If the user has never registered
            before, they will be asked to register.

      4.    Registration: When the user enters the registration area, s/he will
            be asked to provide basic identifying information (See "General
            Registration" above).

      5.    Credit card info: The user will then be shown a page that provides a
            secure connection for credit card information. The user will be
            asked to give the credit card number, type (VISA, MasterCard, AMEX,
            Discover), and expiration date.

      6.    Credit card validation: The credit card is validated, and the user
            is given confirmation that they are about to be charged for the
            requested full text article(s) and/or journal subscription(s).

      7.    Fax delivery/other purchase options: An option to have the article
            faxed to them for an additional fee (to be determined) is also
            offered.

      8.    Transaction confirmation: Once the user has completed the above
            steps, a receipt listing all purchases is shown on the page; a copy
            will also be emailed to them.

      9.    Transaction cancellation: If the user cancels the transaction, then
            they are returned to the abstract of the article.

      10.   Content access: After the user confirms the charge, s/he is given
            access to the content for a specified period of time (hours/days to
            be determined.)

            Articles are provided to the user in both PDF and HTML format

- --------------------------------------------------------------------------------
Purchases
- --------------------------------------------------------------------------------

      The scenarios below outline single document purchases. There also will be
      a facility to purchase multiple documents in a shopping basked like
      manner.

Single Document Purchase Registered User with CC Information

      In this scenario, a registered user requests a document to which they do
      not currently have access. For example, they may be viewing an abstract
      from a journal that is not part of their subscription, or they may be
      referencing a new document (full text) In this scenario we assume that the
      user has a credit card on file or an open purchase order (PO).

      1.    Registration update: At the end of an abstract, a link is provided
            which enables the user to purchase a related document or product
            (i.e., full text article, journal subscription, book, etc.) The link
            brings the user to a page that offers purchase options, lists the
            price of the full text article and allows registered users to enter
            their user name and password. Non-registered users would have to
            register in order to enter credit card information.

      2.    Login: Registered users will log on, confirming registration. Then
            they will be shown a price confirmation and delivery options.

      3.    Optional fax delivery: If the requested document is an article, the
            user will be offered an option to have the article faxed for an
            additional fee (to be determined).

      4.    Transaction confirmation: Once the user has completed the above
            steps, a receipt listing all purchases is shown on the page; a copy
            will also be emailed to them.

      5.    Transaction cancellation: If the user cancels the transaction, they
            are returned to the abstract of the article.

      6.    Content access: After the user confirms the charge, s/he is given
            access to the content for a specified period of time (hours/days to
            be determined.)

            Articles are provided to the user in both HTML and PDF formats.

Single Document Purchase Registered User without CC Information

      In this scenario, a registered user requests to see a document to which
      they do not currently have access. For example, they may be viewing an
      abstract from a new journal and decide they would like to subscribe. In
      this scenario, we assume that the user does not have a credit card on file
      or an open PO.

      1.    Registration update: At the end of an abstract, a link is provided
            which enables the user to purchase a related document or product
            (i.e., full text article, journal subscription, book, etc.) The link
            brings the user to a page that offers purchase options, and lists
            the price of the full text article. The user will be asked to a)
            register, or b) login.

      2.    Login. Registered users will login.

      3.    Credit card info: Then if they do not have credit card information
            on file or if their credit card has expired, they will be shown a
            page which provides a secure connection for credit card information.
            The user will be asked to give the credit card number, type (VISA,
            MasterCard, AMEX, Discover), and expiration date.

      4.    Credit card validation: The credit card is validated, and the user
            is given confirmation that they are about to be charged for the
            requested full text article(s) journal subscription(s), etc. (Any
            relevant discounts will be shown on screen at this time.)

      5.    Optional fax delivery: If the requested document is an article, the
            user will be offered an option to have the article faxed for an
            additional fee (to be determined).

      6.    Transaction confirmation: Once the user has completed the above
            steps, a receipt listing all purchases is shown on the page; a copy
            will also be emailed to them.

      7.    Transaction cancellation: If the user cancels the transaction, they
            are returned to the abstract of the article.

      8.    Content access: After the user confirms the charge, he/she is given
            access to the content for a specified period of time (hours/days to
            be determined).

            Articles are provided to the user in both HTML and PDF formats.

Single Document Purchase Registered User using Purchase Order

      In this scenario, a registered user requests a document to which they do
      not currently have access and choose to pay via an existing purchase order
      which they have set up with Blackwell/Munksgaard. If they do not have a
      purchase order, they will be asked to contact Blackwell/Munksgaard.

      1.    Registration update: At the end of an abstract, a link is provided
            which enables the user to purchase a related document or product
            (i.e., full text article, journal subscription, book, etc.) The link
            brings the user to a page that offers purchase options, and lists
            the price of the full text article. The user will be asked to a)
            register, or b) login.

      2.    Login. Registered users will login with an account that has been
            tagged for all charges to be applied to an existing purchase order.

      3.    Purchase Order validation: The purchase order is validated to assure
            that this charge will not go over the total amount on the purchase
            order. The user is given confirmation that they are about to be
            charged for the requested full text article(s). (Any relevant
            discounts will be shown on screen at this time.)

      4.    Optional fax delivery: If the requested document is an article, the
            user will be offered an option to have the article faxed for an
            additional fee (to be determined).

      5.    Transaction confirmation: Once the user has completed the above
            steps, a receipt listing all purchases is shown on the page; a copy
            will also be emailed to them.

      6.    Transaction cancellation: If the user cancels the transaction, they
            are returned to the abstract of the article.

      7.    Content access: After the user confirms the charge, he/she is given
            access to the content for a specified period of time (hours/days to
            be determined.)

            Articles are provided to the user in both HTML and PDF formats.

Additional Subscription Purchase

      Online users will be provided with several opportunities throughout the
      site to subscribe to other journals; these purchase options will be
      inserted in areas that contextually will promote the likelihood of a sale.

USER SCENARIOS                                                           LINKING
- --------------------------------------------------------------------------------

      The following scenario provides an example of how the need for additional
      full text articles and/or a journal subscription results in a sale.

      1.    Point of entry: A user reads an article in a journal to which they
            subscribe. Searching for more information in this subject area, the
            user clicks on the link to related articles.

      2.    Exposure to new journal: After viewing the list of related articles,
            the user notes that the articles of the most interest are all in a
            journal to which s/he does not currently subscribe. At this point
            the user has a choice: s/he may either purchase the full text of
            some or all the articles, or consider a subscription to the journal
            itself, which will provide unlimited access to these and other
            articles year-round. The user decides to find out more information
            about the journal.

      3.    Journal description: All journal titles will be linked. When the
            user clicks on a journal link, he/she will see a page that provides
            a brief description of the journal, the frequency of publication,
            and pricing information.

      4.    Purchasing procedure: The user decides to purchase the journal.
            Since this user has already subscribed to at least one other
            journal, his/her identification and credit card data are already
            stored in the system.

            The user is given the option of charging the subscription to the
            existing account, or entering new credit card information. (See
            "Credit Card Subscription Registration" above).

      5.    Confirmation of purchase: Once the user has indicated which credit
            card is to be charged, the purchase is charged and validated. The
            user will then be shown a page that provides a receipt for the
            journal subscription purchase. Confirmation of the purchase will
            also be sent to the user via email.

      6.    Other tie-ins to purchase: After confirmation, the user may link to
            his/her own custom page to find that the new subscription has been
            documented, and the custom page updated.

      7.    Next destination: At the end of the transaction, the user will be
            shown the selected volume of the journal.

Linking
- --------------------------------------------------------------------------------

Bibliographic Linking within an Article

      This scenario illustrates how a user would link to and from bibliographic
      information contained within an article.

      1.    Reference links: Reference citations within all articles will be
            linked to bibliographic references (or endnotes.) When the user
            clicks on the citation in the article, a page showing the complete
            listing of references for that article will be displayed.

      2.    Database links: When the user clicks on the MEDLINE link, s/he will
            be shown the corresponding MEDLINE abstract for the cited article,
            if the journal is indexed for inclusion in MEDLINE. (Similar
            functionality will exist with ISI Web of Science).

      3.    Full text/Journal subscription purchase option: If full text is
            available for the cited reference, it will be offered for purchase
            at this point; journal subscription purchase may be offered as well.
            Abstracts will also be available from the references. These purchase
            options will be displayed along with pricing information. If the
            user is not a subscriber to the cited journal, and chooses to
            purchase the article, or subscribe to the journal, new pages

            leading them through the purchase process will automatically be
            shown. (See "Single Document Purchase" and "Additional Subscription
            Purchase" above.)

      4.    Subscription tracking: If the user is already a subscriber to the
            journal that contains the selected article, the user will be
            informed that they may access the article free.

      5.    Other reference options: All articles will also contain a side bar
            which lists (and links to) other full text articles available within
            the Blackwell/Munksgaard collection that references this article
            (forward bibliographic references).

      6.    In Press Bibliographic Links: Links will not exist to bibliographic
            references that are still in press. However, the system will check
            regularly to link them once the article has been published.

      7.    Exit from abstract: The user will also be able to return to the
            previous article from the abstract.

Related Information Links

      When viewing an article, the user will be provided with a side bar that
      outlines several related links pertaining to the article they are
      currently reading. In this scenario, we highlight some of the different
      types of links that may be offered.

      1.    Author listing: The names of all authors of the current article will
            be provided as links. When the user clicks on the link of a selected
            author, s/he will be presented with a listing of other articles
            written by that author. These titles will be linked to the
            corresponding abstract and/or full text. If available, full text
            purchase and/or PDF versions of the selected article will be
            offered.

      2.    Related articles by subject: A listing of related linked subject
            areas will also be provided. When the user clicks on these areas,
            s/he will receive a listing of related articles searched by MeSH
            headings and keywords.

      3.    Related published information: Users interested in reading other
            published information related to the chosen article will find that
            the side bar provides them with links to:

            a. Correspondence (letters, editorials, etc) pertaining to that
            article

            b. Errata (article addenda, corrections, etc.) pertaining to that
            article

      4.    Services: The user will also be able to take advantage of certain
            services. One service will be the ability to email the URL of a
            chosen article to a colleague. When the user chooses this option,
            s/he will be presented with a page to enter an email address, and a
            "send" button.

- --------------------------------------------------------------------------------
Delivery Options Other than HTML
- --------------------------------------------------------------------------------

Downloading PDF

      For those full text articles available in PDF format, the user will be
      given the option of PDF downloading.

      1.    Linked PDF option: On the article page, a link offering the PDF
            option will be found. The users will have the option to download the
            PDF file or have it emailed to them. If the user choose to download
            the document they will be prompted to save it.

      2.    Adobe instructions for downloading: If the user does not have
            Acrobat installed, the download page will explain the need to
            install the Acrobat plug-in. A link to Adobe for detailed
            instructions on how to install the plug-in will be provided.

            If the user does not wish to download Acrobat at that time, the user
            will be prompted to download to their hard drive. They may open the
            PDF document after Acrobat has been downloaded at their convenience.

Fax Delivery

            Users who want the benefits of how an article appears in PDF, but
            who do not wish to download the article in this format, can request
            fax delivery of the article for an additional charge.

      1.    After confirming that the user wishes to purchase an article (or in
            the case of subscriptions, displaying the record on screen), the
            user selects the method of displaying the article: HTML, PDF, or
            "Receive via Fax." Because this is a premium option, the user will
            be asked to confirm the additional fees for fax delivery.

      2.    The user then supplies their fax number.

      3.    To keep costs low, the article is relayed to a commercial fax
            service, such as FaxNet, which sends the information via Web-based
            fax to the user.

Subscriber Features
- --------------------------------------------------------------------------------

User Access to their Custom Page

      Another free feature offered to Blackwell/Munksgaard subscribers is a
      custom-designed page which will provide them with information tailored to
      their unique areas of interest, as well as accounting of their
      subscription plans and other services. The following are highlights of
      features that may be offered to subscribers.

            home page. From this page there is a login link that requires the
            user to enter their user name and password (if they are unable to
            remember their user name and password, they may enter their email
            address, which will then provide them with the correct login
            information via return email). Once the correct information has been
            entered, subscribers are brought to their custom page.

      2.    Custom Page features: The custom page will provide the user with:

            a. Subscription information: All subscription information pertaining

            the duration of subscription.

            b. Updates on new content: Each subscriber will be provided with
            updates on new content that correlates to their specified area(s) of
            interest. This includes new journal articles, correspondence, news,
            etc.

            c. Customer Service: Users can choose to change their password,
            subscriptions, credit card information, etc. by accessing the

            users will be able to view advertising pertaining to their interests
            on this page.

            f. Interactive communication: This area will contain features that
            allow users to communicate via email with Blackwell/Munksgaard. This

            beginning with the most recent publication, and then catalogued in
            descending chronological order, grouped by year.

      b)    Supplements: Any supplemental issues will be grouped with the
            appropriate volume.

      c)    Listing by topic or theme: Each journal listing will also indicate
            relevant topics or themes and page ranges where applicable.

      f)    Keywords

      g)    Article Type (Case report, review, rapid publication, original
            article).

      h)    If applicable, both the MEDLINE Unique Identifier and MeSH terms
            will be available

Full Text

      As users read full text documents, they will be able to access the
      following feature enhancements:

      a)    Linked references: References cited within the body of the article
            will be linked to the bibliographic references (endnotes) for that
            article. A link from the bibliographic reference to the abstract
            (pulled from secondary databases, reference databases), if
            available, is provided. If the corresponding article is available
            online in the Blackwell/Munksgaard collection, a link to the
            full-text with option to purchase will be provided.

      b)    Publication listing by author: All primary authors of the article
            will be listed. The name of each author will be linked so that if
            the user selects the author's name, a listing will be provided of
            other available articles written this author. Again, these articles
            in turn will be linked to their corresponding abstracts. If the
            corresponding article is available online in the
            Blackwell/Munksgaard collection, a link to the full-text with option
            to purchase will be provided.

      c)    Link by keywords: The user will be provided with an option to search
            for other related articles by keyword.

      d)    Email option: If a user would like to send a link to the abstract to
            a colleague, an email window will be available. The user only needs
            to type in the destination email address, and an automatic message
            providing the article title and corresponding URL of the abstract
            will be sent.

      e)    Supplemental Information: Links to supplemental information related
            to the article will be presented if the information is available.

Email version of Table of Contents

      A valuable reminder of newly released publications is the table of
      contents email option. If users choose this feature (usually done during
      subscription registration and payment), they will be sent the new table of
      contents for each journal to which they have subscribed. This feature will
      be available to both subscribers as well as non-subscribing users.

      This scenario shows what a user can do after receiving an emailed version
      of the table of contents. The scenario has two parts: one for text-based
      email, the other for HTML enabled email.

Text Email

      1.    Receipt of email announcement: User receives an email message and
            opens it in their email reader.

      2.    Table of contents listing: The message contains the table of
            contents of the newly published issue of the journal.

      3.    URL linking: The email contains the URL for the Blackwell/Munksgaard
            site. This link will be "live" in most email readers, and will bring
            the user directly to the online version of the table of contents.

      4.    Article linking: Once the user accesses the table of contents, s/he
            will find that all titles are linked to abstracts and the online
            full text article.

HTML Email

      1.    Receipt of email announcement: The user receives an HTML based email
            message, and opens it in their HTML enabled mail reader (e.g.,
            Outlook Express, Outlook 98, Netscape 3.x and higher).

      2.    Table of contents: The message contains the complete table of
            contents, and may be viewed exactly as it would look on the web
            site.

      3.    URL linking: The email contains the URL for the Blackwell/Munksgaard
            site. This link will be clickable in most email readers, and will
            bring the user directly to the online version of the table of
            contents.

      4.    Article linking: Once the user accesses the table of contents, s/he
            will find that all titles are linked to abstracts and the online
            full text article.

- --------------------------------------------------------------------------------
Searching
- --------------------------------------------------------------------------------

      The capacity to search using a variety of keywords and subject headings is
      of critical importance to users, and is an especially important feature of
      the Blackwell/Munksgaard site.

      Users will have the ability to select which set of journals to search.
      Some example sets are: All Full Text Journals, All Subscribed Journals,
      and Journals by particular Publisher. Searches that return a single
      document will forward the user to the abstract or full text if they have
      access to the full text.

      The following scenarios outline several ways in which a subscriber may
      search for content. In addition to offering different types of searching
      mechanisms (i.e., "quick searches" through advanced searches), users will
      also be able to access the searching capability from various areas of the
      site. The following scenarios outline some of the search possibilities.

Quick Search

      A "Quick Search" enables the user to search on a topic (e.g., insulin
      pumps) and obtain a listing of areas where this topic is cited.

      1.    From custom page: From the custom page, users would enter a keyword
            or phrase in the quick search box. The user would select the All
            Subscribed journal set, and then submit the query.

      2.    Results: The search returns a listing of all articles; each linked
            to the full text, PDF, and the abstract where available.

      3.    Save Query: On the results page, the user would have the option of
            saving the query. This adds the query to the user's customized page.

Searching Full Text

      Another option is to search the entire full text of a document for
      specific terms. The following is a sample of how this search could be
      conducted from the user's custom page.

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

      1.    Advanced search option: The user selects the advanced search option
            from the search box.

      2.    Document choice: The user decides to view only abstracts; s/he
            selects this choice from the pull down list of available fields to
            search.

      3.    Subject choice: The user chooses the keyword or phrase they wish to
            search, (e.g., lispro or Humalog), and enters it into the advanced
            search form. This criterion is then added to the query.

      4.    Journal choice: The user then selects the journal set to search, and
            selects the "All Full Text Journals" option. The query is then
            submitted.

      5.    Results: The results contain a listing of all full text articles
            available that match the user's search criteria. Included in this
            list is the price of each full text document that references these
            keywords, with the option to download. In addition, the entries that
            the user has subscription access to would be noted. Results can be
            ordered by relevancy, date, author and journal title.

            The user has the ability to save the query.

Finding an Article Cited Elsewhere

      This scenario provides the user with HealthGate's Citation Finder
      Technology. It allows a subscriber the ability to quickly locate the
      abstract (and the full text if available) from a bibliographic reference.

      1.    Access from custom page: From the registered subscriber's customized
            page, s/he selects the Citation Finder option. The Citation Finder
            page is pre-loaded and has a field for entry of the citation. The
            user can either input the citation information or "copy and paste"
            it into the appropriate fields. The Citation Finder does not require
            information in all fields to execute a search successfully.

      2.    Search criteria: The user then selects the fields, or information,
            which s/he wants to search. Examples of these fields include author,
            journal name, year, volume, issue, article title, and all fields.
            For this example, the user selects author, article title, and
            journal name.

      3.    Results: The user submits the query. If an exact match is found, the
            abstract will be provided. If not, the user is presented with a list
            of matches from which to select.

      Blackwell/Munksgaard will have administrative access to these features.
      All access will be recorded to monitor any possible abuse.

Forgotten Password

      When a user forgets his/her password, the system provides a mechanism for
      the user to look up and find their password without calling customer
      service. This scenario shows how that is accomplished:

      1.    On the login page, a user who has forgotten their password selects
            the link "forgotten password."

      2.    The user is asked to complete a form where the required information
            is user name, first name, and last name.

      3.    The system will search the user database to see if there is a match.
            If there is a match, the system will send the user's password to the
            email address on file. The system will then tell the user that their
            password is being sent to them via email.

      4.    If there is not a match, the system will prompt them to try again or
            allow them to search for user name and password.

Forgotten User Name and Password

      When a user forgets his/her password, the system provides a mechanism for
      the user to look up and find their password without calling customer
      service. This scenario shows how that is accomplished:

      1.    On the login page, a user who has forgotten their password selects
            the link "forgotten password."

      2.    If they do not remember their user name, the user is prompted to
            enter their first name, last name, and email address.

      3.    The system will compare the information supplied by the user against
            the user database and email both the user name and password to the
            address on file if there is a match.

      4.    If there is not a match, the user is instructed to either try again
            or contact customer service.

Changing Password

      Users often want to change their password. The system gives them an easy
      way to do so.

      1.    From the user's personal profile page, the user selects the link to
            "Modify Profile."

      2.    The Modify Profile page will allow them to go to a change password
            form.

      3.    This form will ask the user to type their current password, then
            enter a new password. To confirm, the user is asked to type their
            new password again.

      4.    Upon correct entry (the old password matched the one on file and the
            two new passwords matched), the password will be updated and the
            user will be told that the change has been made.

      5.    If the entry is not correct then the user will be prompted to try
            again.

Changing Email Address

      Users often want to change their email address. The system gives them an
      easy way to do so.

      1.    This feature is available in several places, such as the "Modify
            Profile" page and the regularly scheduled email messages sent by the
            system to the user.

      2.    From the Modify Profile page, the user would select a link to change
            their email address. From an email message, the user selects the
            link embedded in the email. When accessing the appropriate page via
            the email link, the user will be prompted for user name and
            password.

      3.    A form will ask for the users new email address (actually allowing
            them to edit their old email address).

      4.    Upon successful entry, the email address is checked for validity and
            an email message is sent the address for confirmation.

Changing Credit Card Number

      Users often want to change their credit card information on file. The
      system gives them an easy way to do so. This method of updating the credit
      card is also used when the credit card on file has expired. Customers with
      expired credit cards are forced to enter a new credit card when they are
      about to incur additional charges.

      1.    This feature is available from the "Modify Profile" page.

      2.    The user is connected to the secure server and asked to enter the
            new credit card information.

      3.    The credit card is validated with a credit card clearing house.

      4.    If validated, the user is given a confirmation page.

      5.    If the card is not validated, the user is asked to try again.

Changing Other Information

      Users are able to change other information off the "Modify Profile" page
      by selecting the appropriate link. Examples of other information that may
      be changed are postal address, purchasing new subscriptions, and change
      the format in which they received emailed information (HTML verses text).

Journal Setup

      The procedure to setup new journals and their initial entry into the
      system must be initiated by Blackwell/Munksgaard. It is possible to setup
      a journal manually or electronically. The manual procedure for setting up
      a new journal entry is as follows:

      1.    The authorized Blackwell/Munksgaard employee establishes a
            connection to the Administration side of the site.

      2.    When prompted, the employee enters the appropriate user
            name/password and establishes a secure connection.

      3.    The employee selects the option New Journal and enters all
            applicable information, such as title, copyright statements,
            submissions, subscription, etc.

      4.    The employee enters Society information, if applicable, including
            name, links, and board members.

Set Journal Price

      It is possible to setup a journal price manually or electronically. After
      setting up the basic journal information, pricing criteria may be entered:

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

      1.    The authorized Blackwell/Munksgaard employee accesses the
            appropriate journal (the journal must be setup using the Journal
            Setup before establishing the journal price) and selects the option
            "Journal Pricing."

      2.    The employee then assigns the price in multiple currencies, any and
            all subscription plans, including rates for print companion,
            electronic only, and Society membership.

      3.    The employee then assigns pricing for each of the selected
            currencies.

Set Document Price

      1.    The default for all document pricing is established by
            Blackwell/Munksgaard. The Blackwell/Munksgaard employee may override
            the default and establish a special price for documents from a
            specific journal title.

      2.    To override the default document price, the employee accesses the
            appropriate journal (the journal must be setup using the Journal
            Setup before establishing the document price) and selects the option
            "Document Pricing."

      3.    The employee then assigns the revised price in various currencies
            for document delivery.

      4.    The price may be revised to the default at any time by accessing the
            journal and selecting the option to Restore Default Price.

Template Submission

      Initially, templates will be hand loaded by HealthGate Data Corp. to
      insure security and consistency.

      To accomplish this, an FTP location will be provided to allow templates to
      be copied over and reviewed (and tested) prior to releasing them.

Content Publishing
- --------------------------------------------------------------------------------

Issue Loading

      1.    Loading upon receipt: All content for a new issue is loaded upon
            receipt in a single directory.

      2.    Identification: A form is completed which indicates appropriate
            journal, issue, and volume. It is also possible to enter this
            information electronically.

      3.    Back-up: Upon submission, the content is copied to the content
            repository, before conversion. This allows it to be referenced in
            the future.

      4.    Conversion: The content is then converted to our internal Extensible
            Markup Language (XML) format.

      5.    Storage: The XML version is then stored in the content repository.

      6.    Parsing: The XML is then parsed to add more information, including
            tags to link bibliographic information and related information.

      7.    Storage of parsed content: This parsed XML version is also stored in
            the content repository.

      8.    Conversion to HTML: An Extensible Style Language (XSL) template is
            used to convert the file to HTML.

      9.    HTML on staging: The HTML version is made available on the staging
            server.

Issue Review

      1.    The issue is made available on the staging server

      2.    Email is sent to Blackwell/Munksgaard alerting the appropriate
            personnel that the issue is available for review.

      3.    An employee wishing to review the issue would log on to the staging
            server, and select the content they wish to review. This is limited
            to authorized users only. Authorization is by group of journals.

      4.    The content is presented to them in the same way it is shown to an
            end user. However, they also have access to a tool bar (in a frame).
            The tool bar allows them to approve the content as well as adjust
            some of the properties of the article.

      5.    They can change the price or approve the article for release.

Issue Release

      An issue will be released automatically on the assigned electronic
      publication date if all the articles contained in the issue have been
      edited and approved for release. Blackwell/Munksgaard will be alerted to
      content that has not be reviewed after a predetermined amount of time.

      A Blackwell/Munksgaard employee would access the Journal Publishing
      System, a secure area, and go to the System Control area.

      1.    A list of issues that are ready or awaiting publication would be
            available. When an issue is selected, the listing of properties for
            that issue will be presented.

      2.    The user would be able to adjust any of the properties.

      3.    To publish the issue, the user would set the publication date to the
            following day.

- --------------------------------------------------------------------------------
Third Party Access
- --------------------------------------------------------------------------------

General

      Creating an abstract-only export: To create an abstract-only export, a
      Blackwell/Munksgaard employee will need to determine the list of journal
      abstracts to be included for extract, the formatting of the extract, and a
      user profile of which third parties will have access to the extract file.

      1.    Criteria: Once the above information has been determined, the
            following information will need to be entered:

            a. Frequency of updating abstract information,

            b. Packaging method (tar, zip), push, pull or tape.

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

      2.    Push extracts: For push extracts (extracts that are sent to someone
            either via FTP or email), a user will have to enter the destination
            email address, or the FTP server, directory, user name and password
            to use.

      3.    Pull extracts: For pull extracts (extracts that require someone to
            pull the content off the journal server), a user will have to enter
            the user name and password that the third party will use to retrieve
            the content.

      4.    Tape based abstracts: Tape based abstracts will be handled similar
            to FTP pulls except that they would be loaded to tape and sent via
            postal service.

Abstracts Only (Headers)

      Some customers want the abstracts only. This will allow bibliographic
      database to receive the information in electronic form rather than having
      to re-key the documents. Ideally, all databases would also receive
      information pointing them to the full text version of the documents. The
      directory structure will also be included with this abstract. It is
      possible to create a different directory structure and will have to be
      handled on an ad-hoc basis.

      This scenario will be completed upon the supply of the final version of
      the Blackwell/Munksgaard DTD.

Abstracts and PDF (Headers and PDF)

      This type of export would use the same DTD as the abstracts only, but
      would include a reference to the PDF file inside each header. This extract
      would obviously also include the PDF files.

Full Text Blackwell/Munksgaard DTD

      This export will take the Blackwell/Munksgaard SGML files in full as well
      as graphic files and PDF files.

Full Text in Ovid's DTD

      This export will convert the full text to Ovid's DTD and includes the
      graphic files and PDF files.

Delivery Options for Third Parties

      Third parties will have the option to receive information via HTTP, FTP
      (either sent to them or picked up), tape (4mm, 8mm, DLT) or CD-ROM.

- --------------------------------------------------------------------------------
Reporting
- --------------------------------------------------------------------------------

      This section defines some of the reports available to
      Blackwell/Munksgaard. It is expected that customization of reports will
      continue to be refined over the duration of the project. This will allow
      both HealthGate and Blackwell/Munksgaard to make necessary adjustments. As
      a future direction HealthGate will provide direct access to the SQL
      database (via ODBC or similar methods).

User

      Each time an authorized user logs on, information regarding their usage,
      purchases and transactions will be tracked. From this data, reports may be
      compiled to include the following:

            interest by their readers within a subscription.

      o     Accounting of all charges: Reports will have the capacity to reflect
            accounting of all accrued charges by subscribers, document delivery,
            etc.

Content

      Each time an article is accessed by an authorized user, information
      regarding usage, purchases and transactions will be tracked. These reports
      could be grouped by abstract, article, issue, volume, journal and
      publisher. From this data, reports may be compiled to include the
      following:

      o     Number of documents read by subscribers: The number of times each
            document (full-text article) from a specific issue is accessed by
            subscribers

      o     Number of documents read by non-subscribers: The number of times
            each document (full-text article) from a specific issue are
            purchased by non-subscribers

      o     Advertisements shown per issue: The specific advertisement and
            number of times displayed from each issue.

      o     Accounting of all charges: Reports will have the capacity to reflect
            accounting of all accrued charges by subscribers, document delivery,
            etc. associated with a specific issue

      o     Title and number of subscriptions: The number of subscriptions for
            each journal

Dear Mr Saunders

Proposed Escrow Agreement: Healthgate Data Corp / Blackwell Science Ltd / NCC

I confirm that NCC is willing to enter into our standard form escrow agreement
std001y2k.uk with the following amendments by reference to the appropriate
clauses:

(2)   Add the words "and/or companies in the Blackwell Science Ltd group" after
      "Blackwell Science Ltd".

6.1.6 A new clause: "there is a Change in Control of the Owner. For the purposes
      of this clause, a person shall have "Control" of a company if he holds,
      directly or indirectly, shares which together with shares held by any
      persons acting in concert with him carry 50% or more of the voting rights
      of that company, and "Change in Control" shall be interpreted accordingly.
      Words and phrases in the City Code on Take-overs and Mergers shall have
      the same meaning here."

6.1.7 A new clause: "the Licensee exercises its option under clause 10.4.1 of
      the Licence Agreement".

11.4  Replace with: "If the obligations in clause 31 of the Licence Agreement
      have terminated this Agreement will automatically terminate on the same
      date."

Yours sincerely

                           current functional specification and the Licensee

            of all claims arising under or by virtue of this Agreement shall

            faith believes to be genuine and what it purports to be.

            parties.

      11.4  If the Licence Agreement has expired or has been lawfully terminated
            this Agreement will automatically terminate on the same date.

      11.5  The Licensee may terminate this Agreement at any time by giving

         WHEREAS, VAR markets and sells to companies, institutions and other
entities, alone or in combination with others, interactive information,
communication and transactional services (whether presently existing or
hereafter developed referred to herein as the "VAR Services"); and

         WHEREAS, HealthGate offers several series of information including the
MEDLINE database and other databases through HealthGate's Internet sites,
including HealthGate's Internet sites having the following URLs:
http://www.healthgate.com and http://beWELL.com (the "HealthGate Sites");

         WHEREAS, VAR and HealthGate wish to enter into an agreement providing
for VAR to sell and license certain of HealthGate's series of databases
available through the Internet and other HealthGate products and services to
VAR's clients and prospects through a Co-Branded Site (as defined in Section
1.1) designed for the VAR's clients and prospects.

         NOW, THEREFORE, in consideration of the mutual promises set forth

access the "Co-Branded Site" pursuant to an End-User Agreement; and (ii) persons

to mutually agreed upon standards. The Co-Branded Site shall contain prominent
reference to HealthGate and prominently feature HealthGate's logo in a manner
acceptable to HealthGate. In the event the parties do not mutually agree upon

similar arrangements.

specified in the Termination Notice is timely cured or cure is commenced and
diligently pursued, as provided above, the Termination Notice shall be deemed

including a fee dispute or a dispute arising from an alleged material breach of
this Agreement by a party, shall, on written request of one party served on the

injunctive relief by a court of competent jurisdiction.

X.  MISCELLANEOUS

the other party under this Agreement or in activities related thereto.

         10.2 LIMITATIONS ON DAMAGES. Neither party shall be entitled to
indirect, incidental, or consequential damages, including lost profits based on

any liabilities based on obligations to third parties. In no event shall
HealthGate be liable under this Agreement to VAR for damages exceeding the
amounts paid by VAR under this Agreement.

         For any period of time in which the HealthGate Site is not available to
Authorized Users or not properly functioning through the Co-Branded Site due to
actions or inactions by HealthGate, VAR's remedy shall be limited to an
abatement of that portion of the License Fee attributable to the period of time
of which the HealthGate Site is unavailable or not functioning.

         10.3. FREEDOM OF ACTION. Except as set forth in Section 2.2, nothing in

from independently developing or acquiring and marketing materials and/or
programs that are competitive with the Co-Branded Sites.

independent contractors with respect to all matters pursuant to the Agreement.

any provision of this Agreement shall be effective unless it is set forth in a
writing that refers to this Agreement and is executed by an authorized
representative of both parties. No failure or delay by either party in
exercising any right, power, or remedy will operate as a waiver of any such
right, power, or remedy.

        10.7 THIRD PARTY RIGHTS. This Agreement is not intended and shall not be
construed to create any rights for any third party.

         10.8 FORCE MAJEURE. Neither party shall be liable nor deemed to be in
default of its obligations hereunder for any delay or failure in performance
under the Agreement or other interruption of Service resulting, directly or
indirectly, from acts of God, civil or military authority, act of the public
enemy, war, accidents, natural disasters or catastrophes, strikes, or other work
stoppages or any other cause beyond the reasonable control of the party affected
thereby. However, each party shall utilize it best good faith efforts to perform
such obligations to the extent of its ability to do so in the event of any such
occurrence or circumstances.

         10.10 ENTIRE AGREEMENT; SEVERABILITY. This Agreement, together with the
Schedules and other attachments referenced herein, contains a full and complete
expression of the rights and obligations of the parties. This Agreement
supersedes any and all other agreements, written or oral, made by the parties.
If any provision of this Agreement is finally held by a court or arbitration
panel of competent jurisdiction to be unlawful, the remaining provisions of this
Agreement shall remain in full force and effect to the extent that the parties'
intent can be lawfully enforced.

         10.11 EXHIBITS. All exhibits and attachments referenced in this
Agreement are incorporated herein as though set forth in full. If any provision
of this Agreement conflicts with any Exhibit to this Agreement, this Agreement
shall control with respect to the subject matter of such Exhibit.

         10.12 CAPTIONS & HEADINGS. The headings, titles and captions of the
sections of this Agreement and the Exhibits and Attachments are inserted only to
facilitate reference, and they shall not define, limit, extend or describe the
scope or intent of this Agreement or any provision hereof or any Exhibit or
Attachment hereto, and they shall not constitute a party hereof or affect the
meaning or interpretation of this Agreement or any part hereof.

         10.13 OPERATION OF HOT SITE. HealthGate is currently investigating the
use of appropriate alternate sites for its data center. These sites will serve
as alternative sites or "hot sites" in the event of disaster or any other causes
of interruption of service at its data center facilities. Additionally, these
sites will serve as high-bandwidth access sites for HealthGate's international
clients and partners. VAR is encouraged to submit candidates for the hot sites,
including VARs data center(s).

         10.14 YEAR 2000 - The PROGRAMS(S) requiring date data input of four
digit date years. Provided that input to the PROGRAM(S) comply with this
requirement, for each PROGRAM(S) shipped by VENDOR, VENDOR warrants to DGC
and to the END USER, if any, that the PROGRAM(S) shall, for a period that
commences on such shipment and expires ninety (90) calendar days successful
installation, or March 31, 2001, whichever occurs later, correctly process,
calculate, compare and sequence data from, into and between the twentieth and
twenty-first centuries, including leap-year calculations, when used in
accordance with its user documentation and published specifications and any
other requirements set forty in the applicable PROGRAM ATTACHMENT, provided
that all hardware and software used in combination with such PROGRAM(S)
properly exchange data therewith.

         10.15 ESCALATION OF PROBLEMS. Both parties wish to work together to
assure an effective and efficient implementation, therefore both parties will
have the right to escalate any issue through the other party's organization if
they are not resolved in a timely manner. In the event that an issue cannot
be resolved by the parties' respective Program Manager ("PROGRAM MANAGER"),
the issue shall be referred to designated representatives of each party in
the following manner. B. To prevent any significant disruption in any work
for a PROGRAM ATTACHMENT, the following events will be automatically
escalated: (a) Tasks scheduled but not completed during the month and there
is a disagreement with respect to the source of delay and/or the rescheduling
of such tasks; and (b) Issues that may result in a material change in project
scope and therefore may require additional charges by VENDOR. Issues
involving changes in scope that may be billable include, but are not limited
to, the following: (a) requests for additional training or additional
tailoring assistance, (b) project delays greater than one month or (c)
material changes in the scope of interfaces and conversions. These issues
must be resolved to the mutual written agreement of both parties before any
material changes in scope are acted upon. C. The parties agree that
unresolved issues reported will be discussed within ten (10) business days by
the next level representatives identified in Exhibit 4 who shall work to
resolve the issues amicably and expeditiously. Issues that remain unresolved
will continue to be escalated to the next level of representatives in the
same manner. Should such issue not be resolved via this escalation process,
then the matter may be addressed in accordance with the Mediation of a
PROGRAM Attachment processes set forth below.

         IN WITNESS WHEREOF, duly authorized representatives of the parties have
executed this Agreement as of the date first written above:

              ADVERTISING / SPONSORSHIP AND OTHER FEE ARRANGEMENTS

Commercial Advertising Spots and Promotional Spots

      The Co-Branded Site allows for advertising and sponsorship messages to be
served to the Authorized Users of each Corporate/Institutional Account of the
VAR. The areas of the Co-Branded Site that are targeted for this function shall
be referred to as "Commercial Advertising and Sponsorship Spots". In the
End-User Agreement, each Corporate/Institutional Account of the VAR may accept
or reject this option.

Additionally, the Co-Branded Site allows for the Corporate/Institutional Account
to serve messages on behalf of itself, its donors, corporate and commercial
partners. The areas of the Co-Branded Site that are targeted for this function
shall be referred to as "End-User Promotional Spots".

End User Promotional Spots

The Corporate/Institutional Account shall have the exclusive right to sell and
market the End-User Promotional Spots of the Co-Branded Site to its internal
departments, its donors, corporate and commercial partners. HealthGate will
serve the messages on the End-user Promotional Spots of the Co-Branded Site for
a one-time fee of $100 per campaign ad or message.

      The revenues associated with the End-User Promotional Spots of the
Co-Branded site are earned and retained exclusively by the
Corporate/Institutional Account. Except for the $100 campaign fee(s) noted
above, neither HealthGate nor the VAR participates in any share of such revenues
or affiliated expenses.

Commercial Advertising and Sponsorship Spots

      If the Commercial Advertising and Sponsorship Spot option is selected by
VAR's Corporate/Institutional Account, HealthGate shall have the exclusive right
to sell and serve advertising on the Commercial Advertising and Sponsorship
Spots of the Co-Branded Site. The Corporate/Institutional Account will have the
right to approve or reject each advertiser or sponsor.

Allocation of Commercial Advertising and Sponsorship Spots Revenue

      The revenues associated with the Commercial Advertising and Sponsorship
Spots of the Co-Branded site are earned and collected by HealthGate. HealthGate
shall share the Net Advertising and Sponsorship Revenue (as defined below)
associated with the Commercial Advertising and Sponsorship Spots with the VAR
and the Corporate/Institutional Account as set forth below. "Net Advertising and
Sponsorship Revenue" shall equal all advertising and sponsorship revenue
actually collected for the Co-Branded Site, less HealthGate's reasonable
expenses associated with such advertising revenue, provided such reasonable
expenses shall not


                                       15

exceed 20% of such advertising and sponsorship revenue.

Commercial Advertising and Sponsorship Spots Statements and Payments

      HealthGate will render a quarterly statement ("Statement") to VAR and its
Corporate/Institutional Account of the sales and collections of Commercial
Advertising and Sponsorship Spots revenue relating to the Co-Branded Site within
thirty (30) days after the end of a quarter. Payments to VAR and its
Corporate/Institutional Account for their respective share of Net Advertising
and Sponsorship Revenue that has been collected by HealthGate shall accompany
each Statement for the reported period.

Finder's fee for Advertising and Sponsorship

      In addition to the above schedules, VAR will earn a Finder's fee for
introducing and facilitating the sale of advertising and sponsorship on a
Co-Branded Site to the VAR's corporate clients and partners. Each of these
introductions needs to be registered in writing with HealthGate. Within 10 days
of such registration, HealthGate will notify the VAR of the eligibility of the
account for Finder's fees (without limiting the requirement for eligibility,
potential advertisers which HealthGate has already contacted prior to VAR's
introduction shall not be eligible for finder's fees). VAR will earn a finder's
fee, for all eligible accounts, equal to 10% of the first two years of
advertising and sponsorship revenues collected through transaction with the
referred eligible accounts. The reporting and payment for all such finder's fees
shall be included in the quarterly Statements reporting on Commercial
Advertising and Sponsorship Spots revenue.

Audit Rights

      During the Term of this Agreement and for a period of one (1) year
thereafter, VAR and HealthGate will each maintain accurate and complete books
and records, including copies of all customer and other correspondence, relating
to such party's performance of its obligations under this Agreement.

month period, to audit the other party's books and records which are relevant to
this Agreement as provided for herein upon ten (10) days' prior written notice;
provided however, such audit shall not unreasonably interfere with the business
of either party. Such audits shall be conducted solely by an independent CPA

                         SCHEDULE E OF SUPPORT SERVICES

The following sets forth the SUPPORT SERVICES to be provided to DGC by VENDOR
for PROGRAM(S) for which DGC is entitled to receive SUPPORT SERVICES in
accordance with the applicable PROGRAM ATTACHMENT, and payment by DGC of the
applicable annual Support Services Fees, provided in the Program Attachment, for
EACH End User licensed by or through DGC.

1.    DEFINITIONS

      A. "UPDATE" - means any subsequent release of or change to each
      PROGRAM(S), containing a bug fix, enhancement, modification, or addition
      to the functionality or specifications of the immediately prior release,
      which does not meet the requirements for designation as a VERSION.

      B. "VERSION" - means any subsequent release of or change to a PROGRAM(S)
      that contains a substantial functional enhancement to the immediately
      prior release and is marketed by VENDOR in the following manner:

            1) such release is made generally available to VENDOR's customers
            under a model number or designation different from that used for the
            immediately prior release, and

            2) such release is made generally available to users of the
            immediately prior release at a charge that is separate from and in
            addition to both the original licensing fee and the usual and
            customary support fees charged for support and bug fixes by VENDOR,
            and

            3) VENDOR continues to separately market and support only the
            immediately prior release, while also offering support and bug fixes
            for such subsequent release.

2.    NAMED CONTACTS

      DGC shall designate in writing, as the only DGC representatives authorized
      to contact VENDOR's support center, the names of one Primary and one
      Secondary Support Contact. DGC reserves the right to change such names
      when appropriate.

      service hours that VENDOR makes available to its other distributors. The
      right to use and distribute UPDATES for previously issued licenses for
      PROGRAM(S) is included in the related SUPPORT SERVICES Fees for each End
      User as provided in the Program Attachment. Payment of the SUPPORT
      SERVICES Fee does not entitle DGC to receive or distribute VERSIONS at no
      additional charge from VENDOR. DGC is not obligated to obtain or
      distribute any VERSION but VENDOR is only obligated to support the then
      current and the immediately prior release. VENDOR agrees, at its then
      current standard charges and terms, to make enhancements, changes,
      modifications, and additions to PROGRAM(S), in addition to those required
      or provided by SUPPORT SERVICES, as may be reasonably requested by DGC.

4. NOTICE AND FORMAT

      Prior to issuing any new release, VENDOR shall send DGC notice of the
      existence of a new release, specifying the exact release designation to be
      used by VENDOR for such release.

      applicable computer hardware and related operating system, and iii)
      compliance with VENDOR's internal quality control and assurance
      procedures. UPDATES containing relatively minor changes may be made
      available with the documentation changes specified in a separate release
      notice. UPDATES that contain major modifications or enhancements, and
      VERSIONS, shall be made available with the changes integrated into a
      revised set of documentation. VENDOR shall notify DGC in writing, no later
      than the shipment date thereof, of the problems that are solved and those
      that remain therein, and shall send documentation appropriate thereto. The
      new release shall be supplied as an installable module or a complete
      release, and sent to End User(s) on magnetic media or as an electronically
      transferred file to a End User(s) End User(s) host computer.

      for UPDATES and VERSIONS.

7.    PHONE-CALL SUPPORT

      Phone-call support allows DGC's technical support to obtain information
      directly from VENDOR's support organization. This service is used in
      connection with the following:

            A. Telephone Support Hot-line - VENDOR answers DGC's calls related
            to operation, sysgen and installation, configuration, documentation,
            general product information, and Software Trouble Reporting (STR)
            and Resolution services. The hotline service will be available from
            8 A.M. to 8:00 P.M. Eastern Time. With regard to PROGRAM(S), DGC
            will attempt to reproduce the problem and DGC shall not normally
            contact VENDOR's support organization if the problem is i) related
            to installation, ii) covered in a listing of known problems and
            responses previously provided by VENDOR to DGC, or iii) caused by a
            defect or problem in DGC hardware or the DG/UX operating system.

            B. Product Newsletter - DGC provides and uses for support purposes
            an on-line product newsletter describing proposed changes, future
            releases, information on compatibility and third party software or
            hardware, tips and techniques, articles, and known problems and
            solutions not covered in the STR database, as well as general
            information. VENDOR will provide relevant information to DGC, of the
            type that VENDOR generally provides to its other distributors and
            users, for inclusion in this newsletter.

            C. Known Problems - VENDOR will provide DGC with information
            concerning known problems, including, but not limited to, a
            description, workarounds, and fixes.

            D. Monthly Summary of Escalated Calls - VENDOR agrees to summarize
            all responses to all unresolved STRs in a monthly written report
            that will be provided to DGC within ten (10) days after the end of
            each month, and shall include a description of the specific problem
            resolution actions taken or contemplated, and the status of VENDOR's
            remedial efforts and anticipated time of solution.

8.    TROUBLE REPORTING AND RESOLUTION

      The following process will be used in the support of the DGC customers the
      VENDOR and DGC. The VENDOR will establish a 1-800 pager number and email
      address to facilitate the exchange of information with the DGC customer
      support center. The VENDOR will be


                                       21
<PAGE>

      responsible to provide customer service delivery for their application
      programs until the service call is closed by the DGC customer support
      center.

      The Service Call Process:

            A.    Customer contacts DGC support center via 1 800 DGHELPS
                  hotline.

            B.    DGC support personnel perform initial problem determination in
                  order to establish if the problem is a DG hardware, DG system
                  software or VENDOR software related. If the problem is DG
                  hardware or system software related DG is responsible to
                  render service to the customer.

            C.    If DGC's support organization believes the problem is related
                  to the VENDORS software, the DGC support center will
                  electronically email the VENDOR a document detailing the
                  problem and including DGC's service request reference numbers.

            D.    DGC will follow up the email by paging the VENDORS on call
                  support organization. The page will detail a phone number at
                  which the VENDORS support organization can reach the DGC
                  representative who is in contact with the customer. The DGC
                  and VENDOR representatives will discuss the service problem
                  and establish if the VENDOR will now take responsibility for
                  the service call.

            E.    In the event the service problem is the VENDORS
                  responsibility, the VENDOR will contact the DGC customer and
                  render service.

            F.    When the service problem is corrected by the VENDOR, the
                  VENDOR will electronically email a call closed report to the
                  DGC customer support center detailing the action required to
                  fix the problem.

            G.    The DGC customer support center will then close the service
                  call.

            H.    In the event that the VENDOR determines that the service
                  problem is a DGC hardware or system software problem then the
                  VENDOR will call the 1 800 DGCHELPS hotline and use the
                  reference number that has been sent to the VENDOR via email
                  for this service problem to inform DGC customer support center
                  that the problem remains open and requires DGC attention. The
                  VENDORS responsibility for the call will remain open until the
                  DGC customer support center verifies the problem is DGC
                  harware or system software related.

9.    COMMUNICATION MECHANISM

      With the mutual consent of both parties, communication between the two
      companies will be by electronic mail and direct file transfer. Data
      transmission between the two systems shall be by common carrier.
      Additional communication links may be established.

10.   ADDITIONAL SUPPORT

      VENDOR hereby agrees to provide DGC with reasonable assistance in order
      for DGC to respond to requests for bids or demonstrations involving
      PROGRAM(S).

<PAGE>

            b) In addition to the Basic Rent payable pursuant to Section 5
above, from and after the Commencement Date, for each calendar year of the Term,
Subtenant, as Additional Rent, shall pay (i) the amount by which Additional
Charges payable by Sublandlord for the then current calendar year exceed Base
Additional Charges. Sublandlord shall give Subtenant written notice of
Sublandlord's estimate of the amount of Additional Rent per month payable
pursuant to this Subsection (b) for each calendar year promptly following the
Sublandlord's receipt of Landlord's estimate of the Additional Charges payable
under the Base Lease. Thereafter, the Additional Rent payable pursuant to this
Subsection (b) shall be determined and adjusted in accordance with the
provisions of Subsection 6(c) below.

            c) The determination and adjustment of Additional Rent contemplated
under Subsection 6(b) above shall be made in accordance with the following
procedures:

                  i) Upon receipt of a statement from Landlord specifying the
      estimated Additional Charges to be charged to Sublandlord under the Base
      Lease with respect to each calendar year, or as soon after receipt of such
      statement as practicable. Sublandlord shall give Subtenant written notice
      of its estimate of Additional Rent payable under Subsection 6(b) for the
      ensuing calendar year, which estimate shall be prepared based on the
      estimate received from Landlord (as Landlord's estimate may change from
      time to time) On or before the first day of each month during each
      calendar year, Subtenant shall pay to Sublandlord as Additional Rent
      one-twelfth (1/12th) of such estimated amount together with the Base Rent.

                  ii) In the event Sublandlord's notice set forth in Subsection
      6(c)(i) is not given in December of the calendar year preceding the
      calendar year for which Sublandlord's notice is applicable, as the case
      may be, then until the calendar month after such notice is delivered by
      Sublandlord, Subtenant shall continue to pay to Sublandlord monthly,
      during the ensuing calendar year, estimated payments equal to the amounts
      payable hereunder during the calendar year just ended. Upon receipt of any
      such post-December notice Subtenant shall (i) commence as of the
      immediately following calendar month, and continue for the remainder of
      the calendar year, to pay to Sublandlord monthly such new estimated
      payments and (ii) if the monthly installment of the new estimate of such
      Additional Rent is greater than the monthly installment of the estimate
      for the previous calendar year, pay to Sublandlord within thirty (30) days
      of the receipt of such notice an amount equal to the difference of such
      monthly installment multiplied by the number of full and partial calendar
      months of such year preceding the delivery of such notice.

            d) After the receipt by Sublandlord of a final statement of
Additional Charges from Landlord with respect to each calendar year, Sublandlord
shall deliver to Subtenant a statement of any adjustment to be made for the
calendar year just ended. If on the basis of such statement Subtenant owes an
amount that is less than the estimated payments for the calendar year just
ended, previously paid by Subtenant, Sublandlord shall credit such excess to the
next payments of Rent coming due or, if the term of this Sublease is about to
expire or has expired, promptly refund such excess to Subtenant. If on the basis
of such statement Subtenant owes an amount that is more than the estimated
payments for the calendar year just ended


                                        3
<PAGE>

previously made by Subtenant, Subtenant shall pay the deficiency to Sublandlord
within thirty (30) days after delivery of the statement from Sublandlord to
Subtenant.

            e) For partial calendar years during the term of this Sublease, the
amount of Additional Rent payable pursuant to Subsection 6(b) that is applicable
to that partial calendar year shall be prorated based on the ratio of the number
of days of such partial calendar year falling during the term of this Sublease
to 365. The expiration or earlier termination of this Sublease shall not affect
the obligations of Sublandlord and Subtenant pursuant to this Section 6, and
such obligations shall survive, and remain to be performed after, any expiration
or earlier termination of this Sublease.

      7. Electricity. The Estimated Electricity Payment (as defined in the Base
Lease) shall be $1.00 per square foot of Subleased Premises Rentable Area per
annum, subject to adjustment in accordance with the Base Lease. Subtenant shall
pay the Estimated Electricity Payment to Sublandlord with the Basic Rent
payments and, to the extent the cost of providing convenience electricity to the
Subleased Premises exceeds the Estimated Electricity Payment for any Operating
Year, Subtenant shall pay such excess in accordance with the Base Lease.

      8. Parking. For so long as this Sublease remains in full force and effect
and Subtenant's right of possession of the Subleased Premises has not been
terminated, Subtenant shall at no additional cost lease from Sublandlord parking
permits ("Allocated Permits") for parking spaces in the parking garage or
parking area serving the Building (the "Parking Area") at a ratio of 3.3 parking
permits per one thousand (1,000) square feet of Subleased Premises Rentable
Area. So long as no default exists under this Sublease, parking permits for the
above parking shall be provided to Subtenant for use on an unassigned basis and
in common with the other tenants except five (5) parking permits shall be for
underground "reserved spaces."

      9. Use of Subleased Premises. Subtenant may use and occupy the Subleased
Premises only for the Permitted use (as defined in Section 1.1(o) of the Base
Lease), and for no other purpose whatsoever.

disbursements, which Sublandlord may incur or pay out (including, without
limitation, to the landlord under the Base Lease) by reason of (i) any
accidents, damages or injuries to persons or property occurring in, on or about
the Subleased Premises (unless the same shall have been caused by Sublandlord's
negligence or wrongful act or the negligence or wrongful act of the landlord
under the Base Lease), (ii) any breach or default hereunder on Subtenant's part,
(iii) the successful enforcement of Sublandlord's rights under this Sublease,
(iv) any work done after the date hereof in or to the Subleased Premises except
if done by Sublandlord, or (v) any act, omission or negligence on the part of
Subtenant and/or its officers, partners, employees, agents, customers and/or
invitees, or any person claiming through or under Subtenant.

      13. Assignment and Subletting. In no event shall Subtenant assign this
Sublease or sublease the Subleased Premises or any part thereof without first
obtaining the prior written consent (which consent shall not be unreasonably
withheld) of Sublandlord and Landlord. Any such assignment or sublease shall
also be in accordance with and subject to the terms of the Base Lease.
Notwithstanding any such assignment or sublease, Subtenant shall remain
primarily liable and shall continue to make all rental payments and all other
payments that may become due and payable hereunder to Sublandlord in a timely
manner. Any violation of this Paragraph by Subtenant shall constitute an Event
of Default under this Sublease, entitling Sublandlord to exercise any and all of
the remedies herein provided for an Event of Default by Subtenant, including,
but not limited to, termination of this Sublease.

      14. Subtenant Default. Any one or more of the following events will
constitute an event of default ("Event of Default") by Subtenant under this
Sublease:

                  i) failure or refusal by Subtenant to timely pay any
      installment of Basic Rent, any adjustments thereto, or any other amount
      herein provided to be paid by Subtenant to Sublandlord, where such failure
      shall continue for five (5) days after the same is due; or

                  ii) failure or refusal by Subtenant to perform or observe any
      other term, covenant or provision of this Sublease required to be
      performed or observed by Subtenant, where such failure continues for
      twenty (20) days after written notice to Subtenant from Sublandlord
      (provided, however, if such default cannot be cured within such twenty
      (20) day period and Subtenant commences to cure such default within such


                                        5
<PAGE>

      period and diligently prosecutes such cure to completion, then Subtenant
      shall have an additional reasonable period, not to exceed sixty (60) days,
      to cure such default); or

                  iii) the institution in a court of competent jurisdiction of
      proceedings for reorganization, liquidation, or involuntary dissolution by
      Subtenant, or for its adjudication as a bankrupt or insolvent, or for the
      appointment of a receiver of the property of Subtenant, provided that
      proceedings are not dismissed, and any receiver, trustee, or liquidator
      appointed therein is not discharged within thirty (30) days after the
      institution of said proceedings; or

                  iv) the performance or non-performance of any other obligation
      hereunder, or the occurrence of any other event which, if it remains
      uncured, would result in a Default of Sublandlord under the Base Lease.

                  v) At any time after such an Event of Default has occurred,
      Sublandlord may exercise all rights and remedies provided under the Base
      Lease for a default thereunder, including, but not limited to, declaring
      this Sublease terminated, and Sublandlord may immediately or at any time
      thereafter re-enter the Subleased Premises and remove all persons
      therefrom with legal process, and without prejudice to any of its other
      legal rights, and all claims for damages by reason of such re-entry are
      expressly waived, as well as all claims for damages by reason of any
      eviction proceedings or proceedings by way of sequestration or any other
      legal proceedings which Sublandlord may employ to recover unpaid rents or
      possession of the Subleased Premises. In addition, without limiting the
      foregoing, in the event Sublandlord reasonably believes that Subtenant's
      failure to cure a breach under subparagraph (i) above shall cause a
      default by Sublandlord to occur under the Base Lease, Sublandlord shall
      specifically have the right, upon giving Subtenant not less than three (3)
      days prior written notice thereof, to cure such breach or default and be
      reimbursed by Subtenant immediately upon invoice for all expenses incurred
      by Sublandlord in connection therewith upon demand and presentation of
      invoices therefor. All rights and remedies of Sublandlord herein
      enumerated shall be cumulative and none shall exclude any other right or
      remedy allowed by law or in equity, and said rights and remedies may be
      exercised and enforced concurrently and whenever and as often as occasion
      therefore arises.

      15. Relationship of Parties. Subtenant recognizes that Sublandlord is not
the owner of the Subleased Premises, and that the Landlord is the party with
whom Subtenant would normally deal regarding matters concerning the Subleased
Premises and the Building, and that the Sublandlord shall have no obligation to
deliver or provide any services to the Tenant or the Subleased Premises except
to the extent and only to the extent Landlord delivers such services to
Sublandlord. Accordingly, in the event Subtenant desires any extra services (for
example, additional air-conditioning services other than those provided to the
Subleased Premises under the Base Lease, has any complaints concerning services
required to be provided by Landlord under the Base Lease to the Subleased
Premises; or the improvements thereto, or has any other matters which would
normally be discussed with a landlord, Subtenant agrees to contact Landlord
directly to handle such matters; it being the intention of the parties hereto
that, as to such matters, the only connection between Subtenant and Sublandlord
shall be (the flow-through of rights and obligations of Sublandlord under the
Base Lease, and (the payment of all amounts


                                        6
<PAGE>

payable hereunder by Subtenant to Sublandlord as herein provided).
Notwithstanding the foregoing, Sublandlord agrees to use reasonable efforts to
enforce Landlord's obligations under the Base Lease in the event of a default by
Landlord thereunder. Subtenant also acknowledges that all of the covenants and
obligations of Sublandlord hereunder are expressly subject to the terms and
conditions of the Base Lease. In the event Subtenant requires any additional
services from Landlord for which additional costs are incurred and Subtenant
does not pay Landlord directly for such services, then Subtenant shall pay
Sublandlord such amounts incurred by Subtenant within ten (10) days following
receipt from Sublandlord of Landlord's invoice for such services. Sublandlord
represents and warrants to Subtenant that (i) there are no breaches or defaults
on the part of Sublandlord under the Base Lease; (ii) the Base Lease is in full
force and effect; and (iii) during the Term, Sublandlord will perform all of its
obligations and duties under the Base Lease and will not cause or permit any
breach or Event of Default under the terms of the Base Lease; provided Subtenant
performs all of its obligations under this Sublease. Sublandlord agrees that in
the event that a breach or an Event of Default by Sublandlord should arise under
the terms of the Base Lease, Subtenant shall have the right upon giving
Sublandlord not less than three (3) days prior written notice thereof, to cure
such breach or Event of Default on behalf of Sublandlord, and, in the event
Subtenant so cures the Event of Default, shall further have the right to offset
the reasonable expenses of such curative action against the Rent due hereunder.

      16. Waiver of Subrogation. Anything in this Sublease to the contrary
notwithstanding, Sublandlord and Subtenant each hereby waive any and all rights
of recovery, claim, action or cause of action against the other, its officers,
directors, employees or agents for any damage to their respective property
located in the Subleased Premises or the Premises, regardless of cause or
origin, including the negligence of Sublandlord, Subtenant and such parties'
respective officers, directors, employees or agents, and each covenants that no
insurer or other third party shall hold any right of subrogation against such
other party on account thereof. The provisions of this Paragraph 16 shall
survive the expiration or termination of this release.

      17. Holding Over. In the event Subtenant remains in possession of the
Subleased Premises after the expiration or earlier termination of this Sublease,
then Subtenant shall pay to Sublandlord a base rental equal to two hundred
percent (200%) of the Basic Rent payable prior to the expiration of the Term on
a monthly basis with no proration, as well as all other sums payable hereunder.
No holding over by Subtenant after the expiration or termination of this
Sublease shall be construed to extend or renew the Term or in any other manner
be construed as permission by Sublandlord to hold over. Subtenant shall
indemnify and hold Sublandlord harmless from and against any and all damages
(actual, consequential or otherwise), losses, costs and expenses, including
reasonable attorneys' fees, incurred by Sublandlord reason of such holding over.

      18. Care of the Subleased Premises by Subtenant. Subtenant shall maintain
and repair the Subleased Premises in the manner required of Sublandlord by the
Base Lease and shall not commit or allow any waste to be committed on any
portion of the Subleased Premises. At the expiration or earlier termination of
this. Sublease, Subtenant shall deliver up the Subleased Premises to Sublandlord
in at least the same condition as of the date of this Sublease, excepting only
ordinary wear and tear and any casualty damage and/or repairs which are the
obligation of the Landlord under the Base Lease.

Sublandlord as Tenant under the Base Lease with respect to the Subleased
Premises;

            d) Sublandlord hereby expressly agrees not to do, suffer or permit
anything to be done which would result in a default under the Base Lease or
cause the Base Lease to be terminated or forfeited. In addition, in no event
shall any modification or amendment by Sublandlord to the Base Lease in any
manner affect the terms of this Sublease without the prior written consent of
Subtenant, which consent may be given or withheld in Subtenant's sole and
absolute discretion;

            e) To the extent that any notice or consent is required under this
Sublease, Subtenant shall provide copies of all such notices to Landlord; and

            f) Subtenant and Sublandlord mutually agree to promptly provide each
other with any notices received from Landlord which affect the Subleased

            g) Any non-liability, release, indemnity or hold harmless provision

indemnity or hold harmless provision in the Base Lease for the benefit of Tenant

Subtenant, and any other person intended to be benefited by this provision for
the purpose of incorporation by reference in a sublease.

            h) In all provisions of the Base Lease (under the terms thereof and
without regard to modifications thereof for purposes of incorporation into this
Sublease) requiring the approval or consent of Landlord, Subtenant shall be

                                        8
<PAGE>

            i) In all provisions of the Base Lease requiring the Tenant to
submit, exhibit to, supply or provide Landlord with evidence, certificates, or
any other matter or thing, Subtenant shall be required to submit, exhibit to,
supply or provide, as the case may be, the same to both Landlord and
Sublandlord. In any such instance, Sublandlord shall determine if such evidence,
certificate or other matter or thing shall be satisfactory.

            j) Sublandlord shall have no obligation to restore or rebuild any
portion of the Sublease Premises after any destruction or taking by eminent
domain.

            k) In all provisions of the Master Lease requiring Tenant to

month of the Term, and $131,586.39 (the "Security Deposit"), as security for the
faithful performance and observance by Subtenant of the terms, provisions,
agreements, covenants and conditions of this Sublease. The Security Deposit
shall not be considered an advance payment of Basic Rent or Additional Charges,
and the Security Deposit shall not be considered a measure of Sublandlord's
damages in case of the occurrence of any default under this Sublease. Subtenant
shall not be entitled to receive any interest on the Security Deposit and
Sublandlord may commingle the same with other monies of Sublandlord. In the
event Subtenant defaults in respect to any of the terms, provisions, agreements,
covenants and conditions of this Sublease including, but not limited to, the
payment of Basic Rent or Additional Charges, and provided Subtenant fails to
cure such default after notice from Sublandlord, Sublandlord may, at
Sublandlord's option, from time to time, without prejudice to any other remedy,
use, apply or retain the whole or any part of the Security Deposit not
theretofore applied to Basic Rent or Additional Charges to the extent necessary
to make good any arrears of Basic Rent or Additional Charges or any damage,
injury, expense or liability caused by such default. If Sublandlord shall ever
use the Security Deposit not theretofore applied to Basic Rent to pay the sums
described above, and if this Sublease has not terminated, Subtenant shall
immediately deposit with Sublandlord additional monies equal to the amount so
used within ten (10) days after request therefore. If Subtenant shall fully and
faithfully comply with all of the terms, provisions, agreements, covenants and
conditions of this Sublease, then the Security Deposit (or such amount as shall
not have been applied by Sublandlord) shall be returned to Subtenant within
thirty (30) days after the termination or expiration of this Sublease.

cure the Event of Default.

      24. Severability. In the event that any one or more of the provisions
contained in this Sublease shall be held to be invalid, illegal, or
unenforceable in any respect, such invalidity, illegality, or unenforceability

      27. Consents and Approvals. In any instance when Sublandlord's consent or
approval is required under this Sublease, Sublandlord's refusal to consent to or
approve any matter or thing shall be deemed reasonable if, among other matters,
such consent or approval is required under the provisions of the Base Lease
incorporated herein by reference but has not been obtained from Landlord.
Sublandlord agrees to use reasonable efforts, at no additional cost to
Sublandlord, to obtain such approval or consent from Landlord. Except as
otherwise provided herein, Sublandlord shall not unreasonably withhold, or delay
its consent to or approval of a matter if such consent or approval is required
under the provisions of the Base Lease and Landlord has consented to or approved
of such matter. If Subtenant shall seek the approval by or consent of
Sublandlord and Sublandlord shall fail or refuse to give such consent or
approval, Subtenant shall not be entitled to any damages for any withholding or
delay of such approval or consent by Sublandlord, it being agreed that
Subtenant's sole remedy in connection with an alleged wrongful refusal or
failure to approve or consent shall be an action for injunction or specific
performance and that said remedy of an action for injunction or specific
performance shall be available only in those cases where Sublandlord shall have
expressly agreed in this Sublease not to unreasonably withhold or delay its
consent.

      28. NO REPRESENTATIONS OR WARRANTIES. SUBTENANT HEREBY EXPRESSLY
ACKNOWLEDGES AND AGREES THAT SUBLANDLORD HAS MADE NO REPRESENTATIONS OR
WARRANTIES TO SUBTENANT AS TO THE USE OR CONDITION OF THE SUBLEASED PREMISES OR

hereunder) is conditional upon Landlord consenting to the provisions of this

Landlord's consent shall be borne by Sublandlord; provided, however, that
Subtenant will be solely responsible for any fees or charges associated with the
negotiation of additional provisions in any such consent which are requested by
Subtenant.

      31. Furniture Purchase Agreement. Sublandlord and Subtenant have

                  4.9  RESERVATION OF COMMON STOCK.  The Company will at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock, solely for the purpose of issuance upon the conversion of the
Series E Preferred, the number of shares of Common Stock issuable upon the
conversion of all outstanding Series E Preferred. All shares of Series E
Preferred and Common Stock which are so issuable will, when issued, be duly
and validly issued, fully paid and nonassessable and free from all taxes,
liens and charges. The Company will take all such actions as may be necessary
to assure that all such shares of Series E Preferred and Common Stock may be
so issued without violation of any applicable law or governmental regulation
or any requirements of any domestic securities exchange upon which shares of
stock may be listed (except for official notice of issuance which will be
promptly transmitted by the Company upon issuance).

                  4.10 PROPRIETARY RIGHTS.  The Company will, and will cause
each Subsidiary to, use its best efforts to possess and maintain all material
Proprietary Rights which the Company deems necessary to the conduct of their
respective businesses and own all right, title and interest in and to, or
have a valid license or right for, all material Proprietary Rights used by
the Company or any Subsidiary in the conduct of their respective businesses.

                  4.11 PUBLIC DISCLOSURES.  The Company will not, nor will it
permit any Subsidiary to, disclose the Purchaser's name or identity as an
investor in the Company in any press release or other public announcement or
in any document or material filed with any governmental entity, without the
prior written consent of the Purchaser, unless such disclosure is required by
applicable law or governmental regulations or by order of a court of
competent jurisdiction in which case prior to making such disclosure the
Company will use reasonable efforts to give written notice to the Purchaser
describing in reasonable detail the proposed content of such disclosure and
will permit the Purchaser to review and comment upon the form and substance
of such disclosure.

                  4.12 USE OF PROCEEDS.  The proceeds received by the Company
in connection with the sale of the Shares will be used by the Company for
general corporate purposes, including for working capital, acquisitions and
debt reduction.

                  4.13 CONTENT RESTRICTIONS.  Neither the Company nor any of
its Subsidiaries will host, display, provide or aggregate non-healthcare
information on its proprietary and customer websites that might be considered
pornographic, lewd or obscene in nature. The Purchaser and Blackwell
acknowledge that future issues of "Healthy Sexuality" which are consistent
with the format, content and tone of issues prior to the date of this
Agreement shall not constitute a breach of this Section 4.13.

                  4.14 STATUS OF DIVIDENDS.

                  (i)  The Company will not (i) in any income tax return or
claim for refund of income tax or other submission to the Internal Revenue
Service claim a deduction in respect of amounts paid or payable under the
Series E Preferred, whether as interest or pursuant to any other statutory
provision or regulation now in effect or hereafter enacted or adopted, except
to the extent that any such deduction shall not, in the opinion of counsel
satisfactory to the Purchaser, operate to jeopardize the availability to the
Purchaser of the dividends received deduction (the "Dividends Received
Deduction") provided by Section 243(a)(l) of the Code, or any successor
provision or any similar or corresponding provision under federal law
(collectively, the "Dividends Deduction Laws"), (ii) in any report to
stockholders, or to any governmental body having jurisdiction over the
Company, including, without limitation, any reports or returns required by
Section 6042 of the Code, or otherwise, treat the Series E Preferred other
than as equity capital or the dividends paid thereon other than as dividends
paid on equity capital unless required to do so by a governmental body having
jurisdiction over the accounts of the Company or by a change in application
or interpretation of or a change in generally accepted accounting principles
required as a result of action by an authoritative accounting
standards-setting body, or (iii) except to the extent permitted in clause (i)
above, take any action which would result in the dividends paid by the
Company on the Series E Preferred out of the Company's current or accumulated
earnings and profits being ineligible for the Dividends Received Deduction
provided by any Dividends Deduction Laws. Except as contemplated by the
preceding clause (a)(iii), in the event that the Company has reasonable cause
to believe that dividends paid by the Company on the Series E Preferred out
of the Company's current or accumulated earnings and profits will not be
treated as eligible for the Dividends Received Deduction provided by any
Dividends Deduction Laws, or any successor provision, the Company will at the
Purchaser's request join with the Purchaser in the submission to the Internal
Revenue Service of a request for a ruling that dividends paid on the Series E
Preferred will be so eligible for federal income tax purposes. The expenses
of each party incurred in connection with any such submission will be borne
by such party; provided that the Company agrees that it will pay all expenses
reasonably incurred in connection with any such submission necessitated or
caused by a breach of this Agreement by the Company.

                  (ii)  Notwithstanding the foregoing, nothing contained
herein shall be deemed to preclude the Company from claiming a deduction with
respect to such dividends (i) if the Code shall be hereafter amended or
regulations shall be hereafter promulgated to make it clear that dividends on
the Series E Preferred should not be treated as dividends for federal income
tax purposes, or (ii) in the absence of such an amendment or promulgation and
after a submission by the Purchaser (in which the Company shall join if so
requested pursuant to this section) of a request for ruling or technical
advice, if the Internal Revenue Service shall rule or advise that dividends
on the Series E Preferred should not be treated as dividends for federal
income tax

                                     - 14 -
<PAGE>

purposes or (iii) to avoid the running of the statute of
limitations with respect to the taxable year for which the deduction is
claimed, if the Internal Revenue Service provides formal or informal notice
to the Company upon audit or otherwise that such dividends on the Series E
Preferred should not be treated as dividends for Federal income tax purposes.

                  (iii) In the event (i) of a Final Determination (as defined
below) that, due to any reason other than an act or failure to act of the
Purchaser, dividends on the Series E Preferred are not eligible for the
Dividends Received Deduction, (ii) any Dividends Deduction Laws or any
corresponding state or local laws are amended to reduce below 70% or eliminate
or otherwise limit the Dividends Received Deduction available to the Purchaser
below 70%, or (iii) dividends on the Series E Preferred do not constitute, in
whole or in part, a dividend for federal income tax purposes, the Company shall
pay to the Purchaser with respect to each such dividend payment, no later than
the Payment Due Time (as defined below), an additional payment (the "Gross-Up
Payment") such that the net amount of such Gross-Up Payment retained by the
Purchaser after payment by the Purchaser of any federal, state and local income
tax actually imposed upon such Gross-Up Payment shall equal the sum of (A) the
excess of (x) the federal, state, and local income tax payable by the Purchaser
with respect to such dividend in its taxable year in which the dividend was paid
over (y) the federal, state and local income tax which would have been payable
by the Purchaser in its taxable year in which the dividend was paid if the event
described in (i), (ii) or (iii) had not occurred and (B) any interest or
penalties actually payable by the Purchaser with respect to the amount referred
to in subclause (x) above to the Internal Revenue Service or any other
applicable taxing authority by reason of such events. The calculation required
pursuant to the preceding sentence shall be made assuming that the Purchaser
pays taxes at the highest marginal federal income tax rate in effect during such
year, unless the Purchaser is subject to the tax imposed by Section 55 of the
Code in such year in which case such calculation will be made by considering its
actual federal income tax position for such year.

                  (iv) A "Final Determination" with respect to a federal tax
liability shall mean (i) a decision, judgment, decree or other order by any
court of competent jurisdiction, which decision, judgment, decree or other order
has become final, or (ii) a closing agreement entered into under Section 7121
(or any successor to such Section) of the Code or any other settlement agreement
entered into in connection with an administrative or judicial proceeding and
consented to by the Purchaser. The "Payment Due Time" shall mean 5:00 p.m.
Eastern time, of the day two banking days before the date on which expires the
period allowed by applicable law for timely payment of the tax liability imposed
on the related dividend payment.

                  4.15  ERISA.  Neither the Company nor any Subsidiary shall
incur any material liability with respect to retiree medical or death
benefits or unfunded benefits payable after termination of employment. All
employee benefit plans and arrangements maintained or contributed to by the
Company, any Subsidiary or any ERISA Affiliate shall be maintained in
compliance in all material respects with all applicable law, including any
reporting requirements. With respect to any plan maintained by or contributed
to by the Company or any Subsidiary, neither the Company nor any Subsidiary
will fail to make any contribution due from it under the terms of such plan
or as required by law. An "ERISA Affiliate" for purposes of this Section is
any trade or business, whether or not incorporated, which, together with the
Company, is under common control, as described in Section 414(b) or (c) of
the Code.

                  4.16  BEST EFFORTS.  The Company will take or cause to be
taken all actions and make or cause to be made all filings necessary or
appropriate in connection with the communication of the transactions
contemplated by this agreement and the performance of the Company's
obligations hereunder.

         5.  TRANSFER OF RESTRICTED SECURITIES.

                  (i) Restricted Securities are transferable pursuant to (a)
         public offerings registered under the Securities Act, (b) Rule 144 of
         the Securities and Exchange Commission (or any similar rule then in
         force) if such rule is available, (c) to any Affiliate of the Purchaser
         or Blackwell and (d) subject to the conditions specified in
         subparagraph (ii) below, any other legally available means of transfer;

                  (ii) In connection with the transfer of any Restricted
         Securities (other than a transfer described in Section 5(i)(a), (b) or
         (c) above), the holder thereto will deliver written notice to the
         Company describing in reasonable detail the transfer or proposed
         transfer, together with an opinion of counsel which (to the Company's
         reasonable satisfaction) is knowledgeable in securities law matters (an
         "Approved Counsel") to the effect that such transfer of Restricted
         Securities may be effected without registration of such Restricted
         Securities under the Securities Act. In addition, if the holder of the
         Restricted Securities delivers to the Company an opinion of an Approved
         Counsel that no subsequent transfer of such Restricted Securities will
         require registration under the Securities Act, the Company will
         promptly upon such contemplated transfer deliver new certificates for
         such Restricted Securities which do not bear the Securities Act legend
         set forth in Section 8.4. If the Company is not required to deliver new
         certificates for such Restricted Securities not bearing such legend,
         the holder thereof will not transfer the same until the prospective
         transferee has confirmed to the Company in writing its agreement to be
         bound by the conditions contained in this Section and Section 8.4.

         6.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

issuance of the Series E Preferred hereunder, the issuance of the Common

the years ended December 31, 1996 and 1995 and the unaudited consolidated
statements of income and cash flows for the years ended December 31, 1997 and

any) were prepared in accordance with GAAP, are accurate and complete in all
material respects, are in accordance with the books and records of the
Company, and in the case of unaudited statements, subject to changes
resulting from normal year end adjustments (none of which would, alone or in
the aggregate, be materially adverse to the Company's and its Subsidiaries'
financial condition). All the books, records and accounts of the Company and
its Subsidiaries are in all material respects true and complete, are
maintained in accordance with good business practice and all laws applicable
to its business, and accurately present and reflect in all material respects

ended December 31, 1998 within 30 days of the Initial Closing.

presently reflect any non-cash compensation charges relating to stock option
grants to employees and consultants. Audited financial statements for the
years ended December 31, 1997 and December 31, 1998 will include such
non-cash compensation charges.

                  6.6  ABSENCE OF UNDISCLOSED LIABILITIES.  Neither the
Company nor any of its Subsidiaries has any material obligation or liability
(whether accrued, absolute, contingent, unliquidated or otherwise, whether or
not known to the Company, whether due or to become due) arising out of
transactions entered into at or

                                      - 18 -

or any state of facts existing at or prior to each Closing, other than: (i)
liabilities set forth on the Latest Balance Sheet (including the notes
thereto), (ii) liabilities and obligations which have arisen after the date

expressly disclosed in the other Schedules to this Agreement.

                  6.7  NO MATERIAL ADVERSE CHANGE.  Since January 1, 1998,

         granted under this Agreement, the agreements contemplated hereby and
         the Certificate of Incorporation, if the Company is found to have
         breached its obligations under any such agreement.

                  (ii)  The Company further agrees to indemnify and save
         harmless the Purchaser and Blackwell and its respective officers,
         directors, partners, employees, trustees and agents, each person who
         controls the Purchaser or Blackwell within the meaning of the
         Securities Act or the Exchange Act, from and against any and all costs,
         expenses, damages or other liabilities resulting from any breach of any
         representation, warranty, covenant or agreement set forth in this
         Agreement, and the agreements contemplated hereby by the Company or any
         legal, administrative or other proceedings brought by any third party
         arising out of the transactions contemplated hereby and thereby;
         provided that, if and to the extent that such indemnification is

         contribution to the payment and satisfaction of such indemnified
         liability which shall be permissible under applicable laws.

                  (iii) The indemnified party under this Section 8.1 will,
         promptly after the receipt of notice of the commencement of any action
         against such indemnified party in respect of which indemnity may be
         sought from the Company on account of an indemnity agreement contained
         in this Section 8.1, notify the Company in writing of the commencement
         thereof. The omission of any indemnified party so to notify the Company
         of any such action shall not relieve the Company from any liability
         which it may have to such indemnified party except to the extent the
         Company shall have been prejudiced by the omission of such indemnified
         party so to notify the Company, pursuant to this Section 8.1 In case
         any such action shall be brought against any indemnified party and it
         shall notify the Company of the commencement thereof, the Company shall
         be entitled to participate therein and, to the extent that it may wish,
         to assume the defense thereof, with counsel reasonably satisfactory to
         such indemnified party, and after notice from the Company to such
         indemnified party of its election so to assume the defense thereof, the
         Company will not be liable to such indemnified party under this Section
         8.1 for any legal or other expense subsequently incurred by such
         indemnified party in connection with the defense thereof nor for any
         settlement thereof entered into without the consent of the Company;
         provided that (i) if the Company shall elect not to assume the defense
         of such claim or action or (ii) if the indemnified party reasonably
         determines (x) that there may be a conflict between the positions of
         the Company and of the indemnified party in defending such claim or
         action or (y) that there may be legal defenses available to such
         indemnified party different from or in addition to those available to
         the Company, then separate counsel for the indemnified party shall be
         entitled to participate in and conduct the defense, in the case of (i)
         and (ii)(x), or such different defenses, in the case of (ii)(y), and
         the Company shall be liable for any reasonable legal or other expenses
         incurred by the indemnified party in connection with the defense.

                  8.2  REMEDIES.  Each holder of Series E Preferred will have
all rights and remedies set forth in this Agreement and the Certificate of
Incorporation and all rights and remedies which such holders have been
granted at any time under any other agreement or contract and all of the
rights which such holders have under any law. Any Person having any rights
under any

                                     - 30 -
<PAGE>

provision of this Agreement will be entitled to enforce such rights
specifically, to recover damages by reason of any breach of any provision of
this Agreement and to exercise all other rights granted by law.

                  8.3  TERMINATION; TERMINATION FEE.  This Agreement may be
terminated by the Purchaser or the Company with respect to the Additional
Shares at any time after 60 days from the date of this Agreement if the
Second Closing has not theretofore occurred; provided that a party shall not
be entitled to terminate this Agreement as it relates to the Additional
Shares if the failure of the Second Closing to occur results from a breach of
this Agreement by such party. Without limiting the rights of the Purchaser to
receive a break-up fee pursuant to the Letter of Interest dated January 21,
1999 (the "Letter of Interest") if this Agreement is terminated, unless the
failure of the Second Closing to occur results from a breach of this
Agreement by the Purchaser, the Company shall pay the Purchaser a termination
fee of $125,000 (inclusive of all of the Purchaser's reasonable costs and
expenses incurred in connection with such transaction, including, but not
limited to, due diligence expenses and attorney's fees); provided that the
Company shall not be obligated to pay a termination fee hereunder if the
Company pays the break-up fee provided in the Letter of Interest. In the
event of any such termination, except as provided in this Section 8.3,
neither party shall have any obligation under this Agreement or arising from
such termination, except for willful breaches of this Agreement.

this Agreement will be interpreted in such manner as to be effective and
valid under applicable law, but if any provision of this Agreement is held to
be prohibited by or invalid under applicable law, such provision will be
ineffective only to the extent of such prohibition or invalidity, without

declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any
of such which may be hereafter declared invalid, void or unenforceable.

                  Re:   HealthGate Data Corp.

Ladies and Gentlemen:

      We have acted as counsel to HealthGate Data Corp., a Delaware corporation
(the "Company"), in connection with the issuance and sale to (a) GE Capital
Equity Investments, Inc. ("Purchaser") of 87,364 shares (the "Initial Shares")
of the Company's Series E Redeemable Convertible Preferred Stock, par value $.01
per share (the "Series E Preferred Stock"), and (b) Blackwell Science, Ltd.
("Blackwell") of 174,729 shares of the Company's Series E Preferred Stock (the
"Conversion Shares"). This opinion is being furnished to each of you pursuant to
Section 3.4 of that certain Stock Purchase Agreement, dated as of April 5, 1999
(the "Stock Purchase Agreement"), among the Company, Purchaser and Blackwell. In
connection with this transaction, (i) the Company and each of you have also
entered into that certain Registration Agreement dated as of April 7, 1999 (the
"Registration Agreement"), and (ii) the Company, each of you and stockholders
representing a majority of the outstanding shares of each of the Company's
classes of stock have also entered into that certain Amended and Restated
Stockholders Agreement dated as of April 7, 1999 (the "Stockholders Agreement").
Terms used herein without definition shall have the meanings ascribed to them in
the Stock Purchase Agreement.

      We have examined the originals or certified, conformed or reproduction
copies of all such records, agreements, instruments and documents as we have
deemed relevant or necessary as the basis for the opinions hereinafter
expressed. In all such examinations, we have assumed the genuineness of all
signatures on original or certified copies and the conformity to original or
certified copies of all copies submitted to us as conformed or reproduction
copies. As to various questions of fact relevant to our opinion, we have relied
upon statements or certificates of public officials, officers or representatives
of the Company and others.

      Based upon the foregoing, we are of the opinion that:

      1.    The Company is a corporation duly organized, validly existing and in
            good standing under the laws of the State of Delaware and has full
            corporate power and authority to conduct its business as presently
            conducted, to enter into and perform the Stock Purchase Agreement,
            the Stockholders Agreement and the Registration Agreement, and to
            carry out the transactions contemplated thereby. The Company is duly
            qualified to do business and is in good standing in the Commonwealth
            of Massachusetts, the only United States jurisdiction in which, to
            our knowledge, the Company currently owns property or conducts its
            business.

      2.    The authorized capital stock of the Company consists of 20,000,000
            shares of Common Stock, par value $.01 (the "Common Stock"), of
            which 1,146,895 shares are issued and outstanding prior to the
            Initial Closing and 720,757 of which have been reserved for issuance
            upon conversion of the Series E Preferred Stock, and 834,629 shares
            of Preferred Stock, par value $.01 (the "Preferred Stock"), 1,000
            shares of which are designated "Series A
<PAGE>

            Convertible Preferred Stock," all of which are issued and
            outstanding, 1,000 shares of which are designated "Series B
            Convertible Stock," all of which are issued and outstanding, 1,000
            shares of which are designated "Series C Convertible Preferred
            Stock," all of which are issued and outstanding, 1,667 of which are
            designated "Series D Convertible Preferred Stock," all of which are
            issued and outstanding, and 829,962 of which are designated "Series
            E Redeemable Convertible Preferred Stock," none of which are issued
            and outstanding prior to the Initial Closing. Effective immediately
            after the Initial Closing, 262,093 shares of Series E Preferred
            Stock will be issued and outstanding. There are no other authorized
            classes of capital stock of the Company other than those set forth
            in this paragraph. All of the issued and outstanding shares of
            capital stock of the Company have been duly authorized and validly
            issued and are fully paid and non-assessable. Except as contemplated
            by the Stock Purchase Agreement or the Company's Amended and
            Restated Certificate of Incorporation, as amended, and except as set
            forth on Schedule 6.2 to the Stock Purchase Agreement, to our
            knowledge, (i) no subscription, warrant, option, convertible
            security or other right (contingent or otherwise) to purchase or
            acquire any shares of capital stock of the Company is authorized or
            outstanding, (ii) there is not any commitment of the Company to
            issue any subscription, warrant, option, convertible security or
            other such right or to issue or distribute to holders of any shares
            of the Company's capital stock any evidences of indebtedness or
            assets of the Company, and (iii) the Company has no obligation
            (contingent or otherwise) to purchase, redeem or otherwise acquire
            any shares of its capital stock or any interest therein or to pay
            any dividend or make any other distribution in respect thereof.

      3.    The issuance, sale and delivery of the Initial Shares and the
            Conversion Shares by the Company in accordance with the Stock
            Purchase Agreement have been duly authorized by all necessary
            corporate action on the part of the Company, and such Initial Shares
            and Conversion Shares when so issued, sold and delivered against
            payment therefor in accordance with the provisions of the Stock
            Purchase Agreement, and the Common Stock to be issued upon
            conversion of the Initial Shares and the Conversion Shares will be
            duly and validly issued, fully paid and non-assessable.

      4.    The execution, delivery and performance by the Company of the Stock
            Purchase Agreement, the Registration Agreement, the Stockholders
            Agreement and the Amendment to Purchase Agreements and Registration
            Agreements have been duly authorized by all necessary corporate
            action, and each such agreement has been duly executed and delivered
            by the Company. Each such agreement constitutes the valid and
            binding obligation of the Company, and is enforceable against the
            Company.

      5.    The execution, delivery and performance of the Stock Purchase
            Agreement and the Registration Agreement, and the offer, issuance
            and sale of the Initial Shares and the Conversion Shares under the
            Stock Purchase Agreement, will not conflict with, or result in any
            breach of any of the terms, conditions, or provisions of, or
            constitute a default under, the Amended and Restated Certificate of
            Incorporation or Bylaws of the Company, each as amended to date, or
            any material indenture, lease, agreement or other instrument known
            to us to which the Company is a party or by which it or any of its
            properties are bound or any decree, judgment or order specifically
            naming the Company and known to us.

      6.    Except as obtained and in effect at the Closing, no consent,
            approval, order or authorization of, or registration, qualification,
            designation, declaration or filing with any governmental authority
            is required on the part of the Company in connection with the
            execution and delivery of the Stock Purchase Agreement, or the
            offer, issuance, sale and delivery of the Initial Shares and the
            Conversion Shares, or the other transactions to be consummated at
            the Initial Closing pursuant to the Stock Purchase Agreement.

      7.    The offer, issuance and sale of the Initial Shares and the
            Conversion Shares pursuant to the Stock Purchase Agreement are
            exempt, and the issuance of Common Stock upon conversion
<PAGE>

            of the Initial Shares and Conversion Shares will be exempt, from
            registration under the Securities Act of 1933, as amended.

      We express no opinion as to compliance with applicable anti-fraud
provisions of federal securities laws. We express no opinion as to compliance
with applicable state securities laws.

      The opinions expressed herein are subject to the effect of generally
applicable rules of law that: (a) limit or affect the enforcement of provisions
of any contract that purport to require a waiver of the obligations of good
faith and fair dealing; (b) provide that forum selection clauses are not
necessarily binding on the courts in the forum selected; (c) limit the
enforceability of waivers of the right to trial by jury or rights to notice or
other rights or benefits conferred by operation of law; (d) limit the
availability of a remedy where another remedy has been elected or limit waivers
of remedies or defenses; (e) limit the enforceability of provisions releasing,
exculpating or exempting a party from, or requiring indemnification of a party
for, liability for its own action or inaction or on public policy grounds; (f)
where less than all of a contract may be unenforceable, limit the enforceability
of the balance of such contract to circumstances in which the unenforceable
portion is not an essential part of the agreed upon exchange under such
contract; and (g) govern and afford judicial discretion regarding the
entitlement to attorneys' fees and other costs.

      The opinions on enforceability expressed herein are subject further to the
effect of applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium or other laws affecting the rights of creditors and
secured parties generally, and by general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law), as well
as possible limitations upon the exercise of remedial or procedural provisions
contained in the Stock Purchase Agreement, the Stockholders Agreement or the
Registration Agreement, provided, that such limitations do not, in our opinion,
subject to the other qualifications contained in this opinion letter, make the
remedies and procedures that will be afforded to the Purchaser inadequate for
the practical realization of the principal benefits purported to be provided to
the Purchaser by the Stock Purchase Agreement, the Stockholders Agreement and
the Registration Agreement (subject to the effect of any judicial or other
delays in the availability of such remedies). Notwithstanding the foregoing,
however, we express no opinion as to the enforceability of Section 6 of the
Registration Agreement.

      Whenever our opinion with respect to the existence or absence of facts is
indicated to be based on our knowledge or awareness, we are referring to the
actual knowledge or awareness of Rich, May, Bilodeau & Flaherty, P.C. attorneys
who have given substantive attention to such matters during the course of such
representation, which knowledge or awareness has been obtained by such attorneys
in their capacity as such and is intended to signify that in the course of such
representation, no information has come to their attention which has given them
actual knowledge or awareness of the existence or absence of such facts, and
that we have undertaken no independent investigation either within our firm,
with our clients, or with any other person to determine the existence or absence
of such facts.

      We are members of the bar of the Commonwealth of Massachusetts and do not
hold ourselves out as competent to opine as to matters of law governed by other
states. Accordingly, our opinions are limited to the laws of the Commonwealth of
Massachusetts, the General Corporation Law of the State of Delaware, and the
laws of the federal government of the United States. To the extent that any of
the laws of New York or other laws govern any of the matters as to which we
express an opinion herein, we have assumed, with your permission, that the law
of such jurisdiction is, in all material respects, the same as that of the law
of the Commonwealth of Massachusetts.

      This opinion is rendered only to the addressees and is solely for their
benefit in connection with the transactions contemplated by the Stock Purchase
Agreement, and may not be relied upon by any other person for any purpose
without the prior written consent of the undersigned.

                                    Very truly yours,


                                    RICH, MAY, BILODEAU & FLAHERTY, P.C.

      HealthGate Data Corp. (the "Company") was incorporated in the state of
      Delaware on February 8, 1994. The Company was formed to develop and market
      biomedical and health care related information systems to institutions and
      individuals through the Internet and other media.

      The Company's primary activities since incorporation have been business
      and financial planning, raising capital and research and product
      development. The Company is considered a development stage enterprise as
      defined in Statement of Financial Accounting Standards ("SFAS") No. 7,
      "Accounting and Reporting by Development Stage Enterprises."

      Significant accounting polices followed in the preparation of the
      financial statements are as follows:

      Cash and Cash Equivalents

      The Company considers all highly liquid debt instruments purchased with an
      original maturity of three months or less to be cash equivalents. The
      Company invests its excess cash in a money market fund backed by U.S.
      Government securities. Accordingly, this investment is subject to minimal
      credit and market risk.

      At December 31, 1996 and 1995, the Company's cash equivalents are
      classified as available for sale, and include $ 1,133,505 and $100,000,
      respectively, in money market funds. These securities are stated at cost,
      which approximates fair market value.

      Fixed Assets

      Fixed assets are recorded at cost and depreciated over their estimated
      useful lives using the straight-line method. Fixed assets held under
      capital leases which involve a transfer of ownership are amortized over
      the estimated useful life of the asset. Other fixed assets held under
      capital leases are amortized over the shorter of the lease life or the
      estimated useful life of the asset. Repairs and maintenance costs are
      expensed as incurred.

      Software Development Costs

      The Company incurs software development costs for the planning, design and
      improvement of systems which support content and delivery of the Company's
      services. SFAS No. 86, "Accounting for the Costs of Computer Software to
      be Sold, Leased or Otherwise Marketed," requires capitalization of such
      software development costs incurred subsequent to the establishment of
      technological feasibility of the software and the completion of all other
      research and development activities associated with the systems. Costs
      eligible for capitalization were insignificant in 1996 and 1995.

      Revenue Recognition

      The Company derives revenue primarily from user subscriptions and
      transaction based fees, and from the sale of advertisements under
      short-term contracts. Revenue from user subscriptions is recognized
      ratably over the subscription period, and from usage fees when the service
      is provided.

      Advertising revenue is recognized as the related impressions are
      displayed, provided that no significant Company obligations remain and
      collection of the resulting receivable is probable. To date, the durations
      of the Company's advertising commitments have ranged from one month to
      three months. Company obligations typically include guarantees of minimum
      number of "impressions", or times that an advertisement appears in page
      views downloaded by users. To the extent that minimum guaranteed
      impressions are not met during the contract period, the Company defers
      recognition of the corresponding revenue until guaranteed impression
      levels are achieved. Revenue from advertising barter transactions is
      recognized during the period in which the advertisements are displayed by
      the Company. Barter transactions are recorded at the estimated fair value
      of the advertisements provided, unless the fair value of the advertising
      services received is more evident. During the year ended December 31,
      1996, revenue from barter transactions was approximately $115,000.

      Revenue from a research arrangement was recognized pursuant to the
      agreement as the related work was performed. During the year ended
      December 31, 1996, total revenue recognized and costs incurred under this
      arrangement were $87,171 and $81,442, respectively.

      Advertising Costs

      Advertising costs are charged to operations as incurred. Advertising costs
      were approximately $410,000 and $15,000 in the years ended December 31,
      1996 and 1995, respectively.

      Accounting for Stock-Based Compensation

      In October 1995, the Financial Accounting Standards Board issued SFAS No.
      123, "Accounting for Stock-Based Compensation." SFAS No. 123, which is
      effective for the Company's 1996 financial statements, defines a fair
      value method of accounting for stock-based awards to employees. The
      Company has elected to account for stock-based awards to its employees
      using the intrinsic value approach prescribed by Accounting Principles
      Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees"
      and related interpretations, and has adopted SFAS No. 123 through
      disclosure only (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 liabilities at the date of the financial
      statements and the reported amounts of expenses during the reporting
      period. Actual results could differ from those estimates.

2.    Basis of Financial Statements

      The accompanying financial statements have been prepared on a basis which
      contemplates the realization of assets and the satisfaction of liabilities
      and commitments in the normal course of business. The Company incurred a
      net loss of approximately $2,726,000 for the year ended December 31, 1996
      and at December 31, 1996 has an accumulated deficit of approximately
      $3,908,000.

      The future viability of the Company is dependent on its ability to obtain
      additional financing and to generate cash from operations.

3.    Fixed Assets

      Fixed assets consist of the following:

</TABLE>

      Depreciation and amortization expense on fixed assets was $197,900 and
      $45,824 in 1996 and 1995, respectively, of which $132,055 and $37,689,
      respectively, related to amortization of assets held under capital lease.
      Accumulated amortization on assets under capital lease was $169,744 and
      $37,689 at December 31, 1996 and 1995, respectively.

4.    Redeemable Convertible Preferred Stock

      Issuances

      During 1995, the Company issued 1,000 shares of Series A redeemable
      convertible preferred stock and 1,524 shares of common stock with certain
      anti-dilution provisions. A value of $75,000 was ascribed to the common
      stock and anti-dilution provisions based on their estimated fair value at
      the time of issuance. These anti-dilution provisions were terminated by
      mutual agreement of the Company and the investors in October 1995.

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

      During 1995, the Company issued 250 shares of Series B redeemable
      convertible preferred stock. During 1996, the Company issued 750, 1,000,
      and 1,000 shares of Series B, Series C and Series D redeemable convertible
      preferred stock, respectively. In April and September, 1997, the Company
      issued a total of 667 additional shares of Series D redeemable convertible
      preferred stock to the sole Series D investor for cash proceeds of
      approximately $1,000,000.

      Conversion

      Each preferred share is convertible into common stock at the option of the
      preferred stockholder or automatically upon the closing of an initial
      public offering of the Company's common stock in which proceeds from the
      public equal or exceed $10,000,000. The number of common shares to which a
      holder of the preferred stock shall be entitled upon conversion shall be
      based upon the conversion rates defined by the related stockholder
      agreements (approximately 6.098 for 1, 7.988 for 1, 2.773 for 1 and 4.020
      for 1 for holders of Series A, B, C or D preferred stock, respectively, at
      December 31, 1996). At December 31, 1996, the outstanding preferred stock
      is convertible into a total of 20,879 common shares. The conversion rates
      are to be adjusted for certain dilutive and anti-dilutive events. The
      Company has reserved 6,098, 7,988, 2,773 and 6,702 shares of common stock
      for the conversion of Series A, B, C and D preferred stock, respectively.

      Liquidation, Dissolution or Winding Up of the Company

      In the event of any liquidation, dissolution or winding up of the Company,
      the holders of Series A, B, C and D preferred stock are entitled to
      receive, on a pro-rata basis, $500, $1,600, $1,000 and $1,500 per share,
      respectively, plus all accrued and unpaid dividends.

      Voting, Registration and Other Rights

      The holders of the preferred stock are entitled to vote, together with the
      holders of common stock on all matters submitted to stockholders for a
      vote. Each preferred stockholder is entitled to the number of votes equal
      to the number of shares of common stock into which each Series A, B, C and
      D share is convertible at the time of such vote.

      Dividends

      The holders of the Series A, B, C and D preferred stock are entitled to
      receive cumulative annual dividends in the amount of $50, $160, $100 and
      $150 per share, respectively, whether or not declared by the Board of
      Directors- These dividends are payable upon liquidation, dissolution or
      winding-up of the Company, or upon redemption of the respective preferred
      stock.

      Redemption

      On each of the fifth, sixth and seventh anniversaries of the applicable
      series closing date, the Company is required to redeem 33-1/3 percent of
      the Series A, B, C and D preferred stock at a redemption price equal to
      $500, $1,600, $1,000 and $1,500 per share, respectively, plus accrued and
      unpaid dividends through the redemption date. During 1996 and 1995, the
      Company recorded charges to accumulated deficit of $263,641 and $64,713,
      respectively, to reflect the accretion of the preferred stock to
      redemption value.

5.    Common Stock and Other Stockholders' Equity

      Common Stock

      Each share of common stock entitles the holder to one vote on all matters
      submitted to a vote of the Company's stockholders. Common stockholders are
      entitled to receive dividends, if any, as may be declared by the Board of
      Directors, subject to any preferential dividend rights of the preferred
      stockholders.

      Stock Option Plans

      In June 1994, the Company adopted the HealthGate Data Corp. Stock Option
      Plan for Non-Employee Directors (the "Non-Employee Directors Plan") which
      provided for the granting of non-qualified stock options to non-employee
      members of the Company's Board of Directors. The Non-Employee Directors
      Plan allowed for the grant of options to purchase up to 8.75% of the
      Company's outstanding stock on a fully diluted basis. The exercise price
      of options granted under the Non-Employee Directors Plan could not be less
      than the fair value of the stock on the date of grant, and the options are
      exercisable for seven years from the date of grant. This plan was
      terminated by the Board of Directors on March 10, 1995.

      In June 1994, the Company adopted the HealthGate Data Corp. 1994 Stock
      Option Plan (the "1994 Plan") which provides for the granting of both
      incentive stock options and nonqualified options to employees, directors
      and consultants. The 1994 Plan, as amended, allows for a maximum of
      300,000 options to purchase shares of common stock to be issued prior to
      December 2004. The exercise price of any incentive stock option granted
      under the 1994 Plan shall not be less than the fair market value of the
      stock on the date of grant or less than 110% of the fair value in the case
      of optionees holding more than 10% of the total combined voting power of
      all classes of stock of the Company. Options granted under the 1994 Plan
      are exercisable for a period of not longer than ten years from the date of
      grant.

      The Company applies APB 25 and related interpretations in accounting for
      the 1994 Plan. Since inception (February 8, 1994) through December 31,
      1996, no compensation expense has been recognized for options granted
      under this plan. During 1995 and 1994, the Company granted common stock
      and certain other stock options for services rendered and to be rendered
      with exercise prices below the deemed fair value of the Company's common
      stock. The Company recorded compensation expense over the service periods
      equal to the difference between the deemed fair value of the common stock
      and the exercise price, if any. Had compensation cost attributable to 1994
      Plan and other options been determined based on the fair value of the
      options at the grant date, consistent with the provisions of FAS 123, the
      Company's net losses would not have differed materially from amounts
      reported. Because additional option grants are expected to be made in the
      future, the pro forma effect of applying the fair value method may be
      material to reported results of operations in future years.

      The fair value of each option grant is estimated on the date of grant
      using the Black-Scholes option-pricing model with the following
      assumptions for grants in 1996 and 1995:

                                                        1996           1995

        Expected option term (years)                       4              4
        Risk-free interest rate                          5.7%           6.2%
        Expected volatility                              0.0%           0.0%
        Dividend yield                                   0.0%           0.0%

      The Company has provided a full valuation allowance for deferred tax
      assets, since realization of these future benefits is not sufficiently
      assured at December 31, 1996 and 1995. If the Company achieves
      profitability, these deferred tax assets would be available to offset
      future income tax liabilities and expense.

      At December 31, 1996, the Company has net operating loss carryforwards of
      approximately $3,217,000 for federal and state reporting which expire at
      various dates through 2011. Under the Internal Revenue Code, certain
      substantial changes in the Company's ownership may limit the amount of net
      operating loss carryforwards that can be utilized to offset future taxable
      income or tax liability.

            (c)   Any time or material expenses incurred by HealthGate in excess
      of the time and materials set forth in a Project Outline (as modified in

GEMS and HealthGate, or the expense of HealthGate, which agreement shall have
the effect described in Article III and Section 7.2(b).

including associated technology, developed by HealthGate and funded by GEMS
shall be owned by GEMS and all rights therein together with all intellectual
property rights shall be owned by GEMS, unless HealthGate delivers to GEMS clear
and convincing proof including corroborated records showing prior ownership of
such rights by HealthGate, and GEMS agrees with such ownership, in advance of
such development. HealthGate hereby grants GEMS a royalty-free, irrevocable,
non-exclusive license to allow GEMS to copy, modify, distribute, perform
publicly such portions of the delivered work, and to use any portions of any
associated technology that are not owned by GEMS in connection with GEMS'
commercialization of the delivered work.

      3.4   HEALTHGATE'S RIGHTS IN WORK FOR WHICH GEMS FUNDS DEVELOPMENT. GEMS
hereby grants to HealthGate a royalty-free, irrevocable, non-exclusive license
to allow HealthGate to copy, modify, distribute, perform publicly the technology

monitoring and only without the involvement of any competitors of GEMS including

the licenses and other rights under this Agreement, each party retains ownership
of its respective underlying intellectual property rights. Each party agrees to
take such action as may be reasonably required to effectuate the ownership
provisions of this Article III, including without limitation the execution and
delivery of instruments of assignment, recordation or registration, and the
giving of truthful testimony.

      3.6   ENFORCEMENT. Each party shall promptly notify the other of any
infringement or other violation by any third party of any patent, copyright,
trade secret, trademark or other intellectual property right related to the
Products. The party owning such right may enforce such right against such third
party, and the other party shall reasonably cooperate with such enforcement at
the enforcing party's expense. Any damages or other monetary recovery in the
enforcement action shall be retained by the enforcing party.


                                   ARTICLE IV
                               DISTRIBUTION RIGHTS

      4.1   GRANT OF RIGHTS GOVERNING GEMS PRODUCTS. HealthGate hereby grants
to GEMS and its affiliates an exclusive worldwide right and license to
distribute, and arrange for subdistribution through GEMS subdistributors that
do not engage in any activities that would be deemed Competitive Activities
if engaged in by GEMS, GEMS Products on such terms and conditions as GEMS may
determine, consistent with the provisions of this Agreement.

      4.2   GRANT OF RIGHTS GOVERNING HEALTHGATE PRODUCTS.


                                       9

<PAGE>

      (a)   HealthGate hereby grants to GEMS a worldwide right and license,
exclusive except as provided in this Section 4.2(a), to distribute, and
arrange for subdistribution through GEMS subdistributors that do not engage
in any activities that would be deemed Competitive Activities if engaged in
by GEMS, HealthGate Products on such terms and conditions as GEMS may
determine, consistent with the provisions of this Agreement to the Exclusive
Customers. If GEMS engages in any Competitive Activities, then HealthGate may
convert such right and license to nonexclusive upon 30 days notice to GEMS.
HealthGate may continue to market or sell HealthGate Products to any
Exclusive Customer, for a period of 90 days after execution of this
Agreement, but any resulting sale of any HealthGate Products shall be deemed
a sale by GEMS for purposes of the sharing of Revenues and other provisions
of this Agreement. After the first 90 day period of this Agreement,
HealthGate may deliver to GEMS written notice of a Qualified Lead with any
Exclusive Customer. If within 90 days after receiving such notice from
HealthGate, GEMS fails to consummate a sale to, or receive a commitment from,
such Exclusive Customer, or achieve other significant demonstrated progress
toward a sale to such Exclusive Customer, then HealthGate at its option upon
notice to GEMS may thereafter distribute or arrange for the distribution of
HealthGate Products to such Exclusive Customer.

      (b)   HealthGate hereby grants to GEMS a nonexclusive worldwide right
and license to distribute HealthGate Products, other than to the Exclusive
Customers, on such terms and conditions as GEMS may determine, consistent
with the provisions of this Agreement in those instances in which a customer
desires to purchase HealthGate Products and the distribution to such customer
does not violate any then-existing exclusive distribution obligation of
HealthGate and subject to HealthGate prior consent. In addition, GEMS shall
have the non-exclusive right to distribute HealthGate Products to Quorum.

      4.3   REVOCATION OR TRANSFER OF CONFLICTING DISTRIBUTION RIGHTS. If
HealthGate has previously granted distribution rights to others for any of the
Exclusive Customers, then


                                       10

<PAGE>

HealthGate shall revoke such rights or cause them to be transferred to GEMS in
accordance with all the provisions herein.

      4.4   UNAVAILABLE CONTENT. Promptly after the date of this Agreement,
HealthGate shall exert its best efforts with each of its content providers that
prohibit the distribution of their content through GEMS Products or otherwise
prohibit distribution by GEMS to waive such prohibition and allow such
distribution. HealthGate will regularly keep GEMS informed of HealthGate's
efforts and progress in obtaining such waivers.

      4.5   PROHIBITED DISTRIBUTORS. HealthGate will not distribute or allow the
distribution of any HealthGate Products or any components, portions, modules or
other constituents of HealthGate Products, or any product or service competitive
to HealthGate Products, by any company listed in Exhibit C hereto; provided,
however, the limitation provided under this Section 4.5 shall only apply to the
Healthcare Marketplace and shall not limit HealthGate's ability to enter into
transactions or arrangements not involving the Healthcare Marketplace; and
provided further, HealthGate will be released from the limitation provided under
this Section 4.5 at its option upon 30 days prior notice to GEMS if GEMS engages
in any Competitive Activities.

      4.6   TERMS OF DISTRIBUTION. The general terms and conditions of the
distribution of Products by GEMS will be as set forth in a Standard End User
License Agreement substantially in the form agreed upon by the parties from time
to time.

      4.7   NO BEST EFFORTS OR RESTRICTIONS. The loss of exclusivity by GEMS
with respect to the Exclusive Customers as set forth in Section 4.2 above is
HealthGate's sole remedy for any failure by GEMS to make sales of Products.
Except as expressly set forth herein, GEMS will not be restricted in its conduct
of any activities by this Agreement; the distribution activities of GEMS for the
Products shall be as determined by GEMS in its sole discretion subject to the


                                       11

<PAGE>

terms and conditions of this Agreement; and GEMS shall not be obligated to
undertake any "best efforts" or any other particular commitment level.

      4.8   MEETINGS. The parties will meet approximately each calendar quarter
to discuss market conditions and strategies for the effective sale and
distribution of the Products.


                                    ARTICLE V
                              SERVICES AND SUPPORT

      5.1   WEBSITE DESIGN AND HOSTING. HealthGate, at its expense, shall
design, develop, maintain, update, support and host the websites for all
Products; provided, however, with respect to products, services and applications
that are resident on non-HealthGate servers, HealthGate shall only be
responsible for maintaining the links between HealthGate's servers and such
other servers. Promptly upon request, HealthGate shall deliver to GEMS and, if
required under the applicable end user agreement, to customer's quarterly usage,
tracking and similar information related to each such customer's website, such
information to include, if applicable, page views, numbers of unique visitors,
numbers of visits to sections, advertisers' and sponsors' usage and click
throughs.

      5.2   TRAINING. At the request of GEMS, and on a date and at a location
chosen by GEMS and provided to HealthGate a reasonable time in advance,
HealthGate shall provide one comprehensive training session for the GEMS sales
and marketing force to launch the sales and marketing of the Products by GEMS.
While this Agreement is in effect, on a quarterly basis, and on a date and at a
location chosen by GEMS and provided to HealthGate a reasonable time in advance,
HealthGate will conduct a comprehensive training session for individuals
selected by GEMS as GEMS internal trainers for the sales and marketing of the
Products. In addition, while this Agreement is in effect, HealthGate shall
provide such additional training and sales support to


                                       12

<PAGE>

GEMS as it may reasonably request in the sales and marketing of the Products.
HealthGate and GEMS shall each pay the travel, lodging and other related
expenses of their respective personnel in connection with any of the
above-referenced training. HealthGate shall also bear the cost of the necessary
ancillary print materials related to such training. GEMS and HealthGate shall
share equally the cost of any facilities usage expenses of all such training,
except for training that takes place at HealthGate's offices, for which
HealthGate shall bear such expenses, provided that HealthGate approves such
expenses in advance.

      5.3   SURVIVAL OF SERVICES AND SUPPORT. HealthGate's provision of the
services described in this Article V shall survive termination or expiration of
this Agreement with respect to then active Products customers (i.e. those with
which an end user agreement is then in effect) and Products customers for which
there are commitments prior to termination or expiration.

      5.4   RIGHT OF GEMS TO SUPPORT. If, during or after the term of this
Agreement, HealthGate fails to provide service to one or more Products customer
consistent with the level of service mutually deemed satisfactory from time to
time by HealthGate and GEMS, with such initial level of satisfactory service to
be established by HealthGate and GEMS within 60 days after the date of this
Agreement, GEMS and HealthGate will meet and work together in good faith to
address and resolve any such service level issue. If any such service level
issue is not remedied in a timely manner such that the level of service provided
to such Products customers is not at least equal to the then mutually
agreed to level of service, HealthGate shall fully cooperate with GEMS, to
enable GEMS, at HealthGate's expense, to provide such services; provided,
however, HealthGate's liability under this Section 5.4 shall be limited to the
amount of actual revenue it shall have received from the sale of Products to the
affected customers.

HealthGate on GEMS TiP TV to the extent TiP content has been posted on
HealthGate hosted websites such as HealthGate.com and bewell.com. Such promotion
may be in the form of a tag line reading substantially as "To access a web-based
copy of this program, please contact HealthGate.com." GEMS, at its discretion,
will determine what GEMS content is available for HealthGate sponsored websites
and the prices charged to HealthGate for such content. GEMS may also, with the
assistance of HealthGate, promote the Products in TiP TV magazine. HealthGate
may choose to sponsor TiP programming, subject to program availability. Pricing
for such sponsorship will be set at the then current sponsorship market price
less a discount to be agreed upon by the parties taking into consideration the
development costs expended by GEMS and other market factors, such discount to be
no more than 15%. In exchange for the discounted sponsorship fee, HealthGate
will be named as such program's sponsor.

      6.5   BRANDING. Each party reserves all rights to any name, marks and
logos ("Marks") it may have. GEMS will have the right, but not the obligation,
to include its Marks in the Products, and to prohibit the inclusion of the Marks
or advertising of any company if such company is in competition with GEMS in any
goods or services distributed by GEMS. The Products will also include the name
of HealthGate, consistent with applicable General Electric Company corporate
guidelines including without limitation guidelines to avoid confusion of
customers, sales forces and others and to produce and maintain market identity.
Each use by HealthGate of any Marks of GEMS, whether in advertising or marketing
materials, company announcements or offering circulars, informational materials,
public events, or otherwise, shall


                                       15

<PAGE>

be subject to the prior written approval of GEMS. Neither party shall by this
Agreement obtain any right, title, or interest in or to any Marks of the other
party or its affiliates. Accordingly, neither party shall use any Marks
confusingly similar to or likely to cause confusion with the Marks of the other
or of any other person or entity. This Section 6.5 shall survive termination of
this Agreement. Violation of this Section 6.5 shall entitle the owner of the
Mark to seek any legal or equitable remedy it has, whether arising under this
Agreement or otherwise.

                                 REVENUE SHARING

      7.1   HEALTHGATE PRODUCTS. Unless otherwise agreed by the parties (as, for
example, to address promotional activities or volume accounts), all Revenues
collected by either party for subscriptions to HealthGate Products sold by GEMS,
or for upgrades, services or enhancements thereto (but not including GEMS
Products, which are addressed in Section 7.2 below) sold by either party, shall
be divided such that 70% of the List Price is received by HealthGate and the
remainder is received by GEMS.

      7.2   GEMS PRODUCTS. Unless otherwise agreed by the parties (as, for
example, to address promotional activities or volume accounts), all Revenues
collected by either party for subscriptions to GEMS Products sold by GEMS, or
upgrades, services or enhancements thereto sold by either party, shall be
divided such that:

      (a)   70% of the List Price of any HealthGate Products components in
such GEMS Products is received by HealthGate and the remainder is received by
GEMS, except as provided in Subsection (b) below.

      (b)   If such GEMS Products or upgrades, services or enhancements
thereto shall have been created or developed by HealthGate at its own expense
or partial expense by agreement of

                                       16

<PAGE>

the parties under Section 2.3 above, then the division of Revenues shall be
modified as the parties agree upon in advance of such creation or development
taking into consideration the expense so incurred by HealthGate.

      7.3   ADVERTISING REVENUE. All Revenues collected by either party for
advertisements or other promotional material included in the Products during
the term of this Agreement shall be divided 90% to HealthGate and 10% to GEMS.

      7.4   E-COMMERCE. All Revenues collected by either party from e-commerce
offered on the Products not involving products or services of GEMS or its
affiliates, shall be divided 90% to HealthGate and 10% to GEMS. Any Revenues
collected by either party from e-commerce offered on the Products involving
products or services of GEMS or its affiliates, for the first two and one-half
years following the date of this Agreement, shall be retained 100% by GEMS, and
any such Revenues collected after such two and one-half year period shall be
divided as the parties negotiate in good faith considering (a) the level of
effort expended by each party to enable such e-commerce, (b) prevailing market
conditions, (c) comparable third party web-based distribution fees, (d) the
price points of GEMS Products, (e) the volume of sales and (f) in no event shall
be any less favorable to GEMS than the fees charged by HealthGate to others.

      7.5   SURVIVAL OF REVENUE SHARING. The Revenue sharing arrangements set
forth in this Article VII shall survive the termination or expiration of this
Agreement with respect to then active Products customers (i.e. those with which
an end user agreement is then in effect) and Products customers for which GEMS
has a signed commitment.

      8.1   ACCOUNTING. Reconciliation of accounts in accordance with the
Revenue sharing arrangements set forth in Article VII above shall be made within
45 days after each calendar quarter with respect to Revenues received during
such calendar quarter, by each party delivering to the other party a check (or
by making a wire transfer or in such other reasonable manner as the receiving
party may direct) for the amount due without offset for any amount due from the
other party together with the report described in Section 8.2 below.

      8.2   RECORDS. Each party shall keep complete and accurate records showing
its Revenues hereunder, for the term of this Agreement and a period of one year
thereafter. Each party shall deliver to the other party a written report
accompanying each of the payments described in Section 8.1 above setting forth
the share of Revenues due to the other party and the calculation thereof.

      9.1   LINKING. HealthGate will make available the HealthGate Products for
linking to GEMS websites, and will provide all necessary formatting services and
support for such linking in a manner that is invisible to users. Such services
and support will be on such reasonable terms and conditions as the parties may
agree upon, and no less favorable to GEMS than those granted to others in
similar circumstances.

      10.3  INDEMNITY. Each party will indemnify and hold harmless the other'
from and against any liability, costs or expenses (including attorney fees)
based upon any action, claim or assertion inconsistent with the warranties and
representations of Section 10.1 or 10.2 above. The indemnified party shall
promptly notify the indemnifying party of any such action or assertion and shall
cooperate in the defense thereof. The indemnifying party shall have the right to
direct the defense of any such action, claim or assertion, subject to the
indemnified party's approval of any settlement thereof and the indemnified

During the term of the Agreement, HealthGate covenants to maintain such
insurance policy and to take such steps, as necessary, to name GEMS as an
additional insured under such insurance policy. Evidence of the existence and
amount of the insurance policy shall be provided by HealthGate to GEMS upon GEMS
written request.

      10.5  NO OTHER WARRANTIES. THE WARRANTIES EXPRESSED IN THIS ARTICLE X ARE
IN LIEU OF ALL OTHER WARRANTIES, WHETHER EXPRESSED OR IMPLIED OR ARISING BY
PERFORMANCE, CUSTOM OR USAGE IN THE TRADE, AND THE PARTIES HEREBY DISCLAIM ALL
OTHER WARRANTIES, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

      10.6  NO CONSEQUENTIAL DAMAGES. Except as expressly set forth herein, in
no event shall either party be liable under, or in connection with, this
Agreement for any indirect, special,


                                       21

<PAGE>

incidental, punitive or consequential losses, expenses or damages whatsoever,
including, but not limited to, loss of revenue or profits or increased costs as
a result of inability to operate, inability to fulfill contracts with third

disclaimers in this Agreement shall apply irrespective of the nature of the
cause of the action or demand, including but not limited to breach of contract,
negligence, tort or any other legal theory and shall survive any breach or
breaches and/or failure of the essential purpose of this Agreement, or any
remedy contained in this Agreement.

                                 CONFIDENTIALITY


      11.1  OBLIGATION. Each party agrees that any Confidential Information
furnished or disclosed to it by the other party shall be treated as confidential
by it and used by it only as expressly authorized herein, that it shall not
disclose such Confidential Information to others without the prior written
consent of the disclosing party, and that it shall take all necessary measures
to protect the confidentiality of such Confidential Information that it takes to
protect its own similar proprietary or confidential information (and that such
measures shall in no event be less than those required by law to protect the
confidentiality and proprietary nature of such information), EXCEPT insofar as:

            (a)   expressly provided otherwise herein or in any other written
      agreement with the disclosing party or required by law;

            (b)   such Confidential Information is necessarily disclosed by its
      use in products manufactured and sold or otherwise disposed of by the
      disclosing party; or


                                       22

<PAGE>

            (c)   such Confidential Information is necessarily disclosed to bona
      fide subcontractors of the receiving party provided that such
      subcontractors agree to maintain such Confidential Information in
      confidence and to protect such Confidential Information from disclosure to
      others to the extent of the foregoing requirements of this Section and to
      limit their use of such Confidential Information to fulfilling their
      obligations as a subcontractor or supplier.

      11.2  COOPERATIVE DEVELOPMENT. Without limiting the generality of Section
11.1 above, should any joint development effort be undertaken by the parties
involving software owned by GEMS, then GEMS may in its sole discretion make
source code for such software available to HealthGate to the extent reasonably
necessary for HealthGate to perform the development or maintenance obligations
agreed upon by the parties or provided hereunder. HealthGate shall not use such
source code or software except in performing such obligations and shall not
disclose it to anyone other than its employees who both (a) require access
thereto in order to allow HealthGate to perform such obligations and (b) have
agreed in writing to refrain from using or disclosing it other than as permitted
hereunder.

      11.3  OTHER CONFIDENTIALITY AGREEMENT. Except to the extent modified
hereunder, all the obligations of the Confidentiality Agreement made as of March
25, 1999 between General Electric Company and HealthGate remain in full force
and effect as provided thereunder.

      12.1  TERM. This Agreement shall be for an initial term of one year,
automatically renewed for successive one-year periods unless either party
delivers to the other party written notice of non-renewal at least 90 days prior
to the end of the initial term or any renewal term.

      12.2  EARLY TERMINATION. This Agreement may be terminated by GEMS in its
sole discretion and shall have no further force and effect if, as of June 14,
1999, the transactions contemplated by the Warrant Agreement between General
Electric Company and HealthGate dated on or about the date hereof have not been
closed and the Warrant to be issued to General Electric Company thereunder has
not been issued by HealthGate. GEMS shall have no liability for such termination
and shall retain any other rights or remedies it may have in regard to such
termination. If either party commits a material breach of this Agreement or the
Warrant Agreement, then the other party may deliver written notice of such
breach to the breaching party. If the breaching party fails to remedy such
breach within 30 days after such notice, then the other party may terminate this
Agreement by written notice of termination. A material breach shall be deemed to
include without limitation any failure to remit in a timely manner amounts due
under Article VII above, any violation by HealthGate of the exclusive
distribution rights of GEMS under Article IV above, any breach of any of the
representations or warranties of Article X, any violation by HealthGate of any
of the Confidentiality Obligations of Article XI, and any dissolution,
insolvency, bankruptcy, appointment of a receiver or trustee, making of an
assignment for the benefit of creditors, the commencement of any proceeding
(state or federal) relating to the administration of creditors rights generally,

Article XII, each party shall have all rights and remedies available to it
hereunder and at law or in equity, it being understood that the exercise of any
one remedy is not meant to be exclusive of any other remedy and that all
remedies hereunder are intended to be cumulative. Following termination, the
terminating party may suspend any and all performance hereunder except as
provided under Section 12.4 below.

      12.4  SURVIVAL AND POST-TERMINATION RIGHTS. The provisions of Sections
5.3, 5.4 and Article VIII (to the extent provided in each such Section and
Article) and Articles I, X, XI and XIII and Sections 3.1 through 3.4, 4.7 and
6.5 shall survive any termination or expiration of this Agreement. No
termination or expiration shall in any way terminate or otherwise affect the
right of any user or customer of GEMS with respect to any Products.


                                  ARTICLE XIII
                                  MISCELLANEOUS

exclusive license of any of the copyrights, patents, trade secret rights or
other intellectual property rights in or relating to any of the Products (other
than that security interest referenced in Section 10.1(e) above) shall be deemed
an assignment of this Agreement for purposes of this Section 13.3. Any purported
assignment or other transaction in violation of this Section 13.3 shall be null
and void and of no force or effect.

      13.4  GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of New York without reference to
any conflict of law principles.

      13.5  ARBITRATION. Any dispute under this Agreement shall be finally

action, suit or proceeding brought to enforce or defend any rights or remedies

contract or otherwise.

      13.6  CONFIDENTIALITY. No public announcements may be made of the contents
of this Agreement except as mutually agreed in writing.

      13.7  RELATIONSHIPS OF THE PARTIES. Each party is an independent

name of the other party or to bind the other party to any contract, agreement or
undertaking with any third party.

      13.8  INTERPRETATION. When a reference is made in this Agreement to a
Section, such reference shall be to a Section of this Agreement unless otherwise
indicated. Whenever the words "included", "includes" or "including" are used in
this Agreement, they shall be deemed to be followed by the words "without
limitation." References to a person are also to its successors and assigns, and
references to any statute are also to all rules, regulations and orders

     Content. HealthGate shall not make any changes to the Content without the
     prior written consent of the Society. The Sites shall include copyright
     notices and other notices of right title and interest to the Content. Both
     parties agree, within 15 working days after executing this Agreement, to

          the Society, from portions of the Content to the corresponding
          original articles found on the NEJM site. HealthGate shall manage such
          links to the NEJM site. Any revenue associated with said links shall

          association with this Agreement.


7.   EXCLUSIVITY.

     (a)  HealthGate shall have exclusive rights to distribute the Content
          through its own Web sites or through sites owned or operated by
          HealthGate during the term of this Agreement. HealthGate may
          distribute the Content to other Web sites, not owned or operated by
          HealthGate, with the prior written approval of the Society, whose
          approval shall not be unreasonably withheld.

     (b)  Notwithstanding the foregoing, the Society shall, six months after
          the delivery of the first issue of the Content, have the right to
          post the Content on one or more of the Society's web sites. This
          exception shall be granted provided that each article displayed at
          the NEJM Web site (i) includes a message that the Content was
          developed jointly by the Society and HealthGate; (ii) is provided in
          the same manner in which it is made available on the HealthGate site,
          including, but not limited to, user registration, release date,
          advertising sold by HealthGate (provided that such advertising
          complies with the Society's advertising policies for the web site)
          and served from the HealthGate server, and any value added services
          provided by HealthGate, such as links to the MEDLINE database or to
          other sites or services; (iii) includes a link to the Content hosted
          by HealthGate; and (iv) is posted on the same schedule as the Content
          is posted by HealthGate. This exception to Section 7 (a) shall not
          waive either party's rights as outlined elsewhere in this Agreement.

8.   INITIAL TERM. The Initial Term of this Agreement shall commence upon
     delivery of the Content to HealthGate and, unless terminated earlier as set
     forth herein, shall continue for a period of two (2) years after such date
     (the "Initial Term").

9.   RENEWAL. After the Initial Term, HealthGate may renew this Agreement
     (subject to the termination provisions of Section 10) for up to two (2)
     additional 18 month periods, provided that HealthGate's option to extend
     the term shall be conditioned upon there being no material uncured defaults
     or breaches by HealthGate at the time of HealthGate's exercise of such
     option.

10.  TERMINATION.

     (a)  Either party may terminate this Agreement without cause upon the last
          date of the Initial Term or any subsequent renewal term by giving
          written notice of termination

          to the other party no later than ninety (90) days prior to the end of
          the Initial Term or of any subsequent one year term. Upon termination
          by either party, HealthGate may continue to use the Content produced
          during the term of this Agreement to fulfill any outstanding
          commitments, obligations, or contracts for a period no longer than
          12 months after termination or expiration of this Agreement, subject
          to terms and conditions which shall be mutually agreed upon by the
          parties at the time.

     (b)  In the event that any use of the Content by HealthGate is, in the
          opinion of the Society, injurious to the reputation or goodwill of
          NEJM, the Society may terminate this Agreement upon 30 days written
          notice to HealthGate, unless HealthGate shall remedy such use within
          the 30 day period or be undertaking actions to remedy such use to the
          satisfaction of the Society.

confirmation by such Person that such Person will abide by the foregoing
confidentiality provisions.

     supplies which if unpaid might by law become a lien upon any of its
     property, to the extent to which the failure to so pay or discharge might
     reasonably be expected to have a material adverse effect upon the business,
     assets, financial condition, results of operations or prospects of the
     Company and its Subsidiaries taken as a whole, unless and to the extent
     that the same are being contested in good faith and by appropriate

     business, assets, financial condition, results of operations or prospects
     of the Company and its Subsidiaries taken as a whole, unless and to the
     extent that the same are being contested in good faith and by appropriate

pursuant to the requirements of either the Securities Act or the Securities
Exchange Act, the Company will file all reports required to be filed by it under

time) or any similar rule or regulation hereafter adopted by the Securities and
Exchange Commission.

transmitted by the Company upon issuance).

Company in any press release or other public announcement or in any document or
material filed with any governmental entity, without the prior written consent
of the Purchaser, unless such disclosure is required by applicable law or
governmental regulations or by order of a court of competent jurisdiction in
which case prior to making such disclosure the Company will use reasonable
efforts to give written notice to the Purchaser describing in reasonable detail
the proposed content of such disclosure and will permit the Purchaser to review
and comment upon the form and substance of such disclosure. Notwithstanding the
foregoing, the Company may describe its strategic affiliation with the


                                       6

<PAGE>

unreasonably withheld.

          3.9  CONTENT RESTRICTIONS. Neither the Company nor any of its
Subsidiaries will host, display, provide or aggregate non-healthcare information
on its proprietary and customer websites that might be considered pornographic,
lewd or obscene in nature. The Purchaser acknowledges that future issues of

plan maintained by or contributed to by the Company or any Subsidiary, neither
the Company nor any Subsidiary will fail to make any contribution due from it
under the terms of such plan or as required by law. An "ERISA Affiliate" for
purposes of this Section is any trade or business, whether or not incorporated,
which, together with the Company, is under common control, as described in
Section 414(b) or (c) of the Code.

          3.11 BEST EFFORTS. The Company will take or cause to be taken all
actions and make or cause to be made all filings necessary or appropriate in
connection with the consummation of the transactions contemplated by this
agreement and the performance of the Company's obligations hereunder.


     4.   TRANSFER OF RESTRICTED SECURITIES.

          (i)  Restricted Securities are transferable pursuant to (a) public
     offerings registered under the Securities Act, (b) Rule 144 of the
     Securities and Exchange Commission (or any similar rule then in force) if
     such rule is available, (c) to any Affiliate of the Purchaser and (d)
     subject to the conditions specified in subparagraph (ii) below, any other
     legally available means of transfer;

          (ii) In connection with the transfer of any Restricted Securities
     (other than a transfer described in Section 4(i)(a), (b) or (c) above), the
     holder thereto will deliver written notice to the Company describing in
     reasonable detail the transfer or proposed transfer, together with an
     opinion of counsel which (to the Company's reasonable satisfaction) is
     knowledgeable in securities law matters (an "Approved Counsel") to the
     effect that such transfer of Restricted Securities may be effected without
     registration of such Restricted Securities under the Securities Act. In
     addition, if the holder of the Restricted Securities delivers to the
     Company an opinion of an Approved Counsel that no subsequent transfer of
     such Restricted Securities will require registration under the Securities
     Act, the Company


                                       7

<PAGE>

     will promptly upon such contemplated transfer deliver new certificates for
     such Restricted Securities which do not bear the Securities Act legend set
     forth in Section 7.3. If the Company is not required to deliver new
     certificates for such Restricted Securities not bearing such legend, the
     holder thereof will not transfer the same until the prospective transferee
     has confirmed to the Company in writing its agreement to be bound by the
     conditions contained in this Section and Section 7.3.

     5.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY. As a material
inducement to the Purchaser to enter into this Agreement and purchase the

     indemnified party different from or in addition to those available to the
     Company, then separate counsel for the indemnified party shall be entitled

extent of such prohibition or invalidity, without invalidating the remainder of
this Agreement. It is hereby stipulated and declared to be the intention of the
parties that they would have executed the remaining terms, provisions, covenants
and restrictions without including any of such which may be hereafter declared
invalid, void or unenforceable.

SG Cowen Securities Corporation
Financial Square, 27th Floor
New York, NY 10005
   As representative of the
   several Underwriters

Re: HealthGate Data Corp.

   o  Shares of Common Stock

Dear Sirs:

            In order to induce SG Cowen Securities Corporation ("SG Cowen"),
Banc of America Securities LLC and Volpe Brown Whelan & Company, LLC
(collectively, the "Underwriters") to enter into a certain underwriting
agreement with HealthGate Data Corp., a Delaware corporation (the "Company")
with respect to the public offering of shares of the Company's Common Stock, par
value $0.01 per share ("Common Stock"), the undersigned hereby agrees that for a
period of 180 days following the date of the final prospectus filed by the
Company with the Securities and Exchange Commission in connection with such
public offering, the undersigned will not, without the prior written consent of
SG Cowen, on behalf of the several Underwriters, (1) directly or indirectly,
offer, sell, assign, transfer, encumber, pledge, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant to purchase, lend, or otherwise dispose of, other
than by operation of law, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock (including,
without limitation, Common Stock which may be deemed to be beneficially owned by
the undersigned in accordance with the rules and regulations promulgated under
the Securities Act of 1933, as the same may be amended or supplemented from time
to time (such shares, the "Beneficially Owned Shares")) or (2) enter into any
swap or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of Common Stock whether any such
transaction described in clause (1) or (2) above is to be settled by delivery of
Common Stock or such other securities, in cash or otherwise. The undersigned
shall, however, be entitled to (i) transfer the Company's Common Stock or
securities convertible into or exchangeable or exercisable for any Company's
Common Stock to an affiliate of the undersigned, provided however, that any such
transferee agrees to be bound by the terms of this letter and to enter into a
similar agreement with SG Cowen on its own behalf, and (ii) sell any Company
Common Stock purchased in the open market by the undersigned at or following
consummation of the initial public offering.

            Anything contained herein to the contrary notwithstanding, any
person to whom shares of Common Stock or Beneficially Owned Shares are
transferred from the undersigned shall be bound by the terms of this Agreement.

            The undersigned is executing and delivering this letter on the
express understanding that each director, each executive officer, each
individual and entity listed in the "Principal Stockholders" table in the
Company's Registration Statement on Form S-1 (Registration No. 333-76899) and
certain other holders of the Company's Common Stock representing in the
aggregate more than 93% of the Company's outstanding Common Stock (assuming
conversion of all outstanding preferred stock to common stock and including the
undersigned's stock) has executed and delivered to SG Cowen a letter
substantially similar to this letter. If such understanding is incorrect, this
letter shall immediately become null and void. If any holder of the Company's
Common Stock who has executed such a lock-up letter is released with respect to
some or all of such stockholder's shares of the Company's Common Stock to effect
a transfer in which the transferee will not be bound to the lock-up arrangements
of the transferor, SG Cowen, upon written request
<PAGE>

from the undersigned, will release in the aggregate the same number of the
undersigned's and its affiliates' shares from such lock-up provisions.

            In addition, the undersigned hereby waives, from the date hereof
until the expiration of the 180 day period following the date of the Company's
final Prospectus, any and all rights, if any, to request or demand registration
pursuant to the Securities Act of any shares of Common Stock that are registered
in the name of the undersigned or that are Beneficially Owned Shares.

            In order to enable the aforesaid covenants to be enforced, the
undersigned hereby consents to the placing of legends and/or stop-transfer
orders with the transfer agent of the Common Stock with respect to any shares of
Common Stock or Beneficially Owned Shares.

            Whether or not the public offering actually occurs depends on a
number of factors, including market conditions. Any public offering will only be
made pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.

            This agreement shall terminate and be of no further force and effect
if the closing of the offering has not occurred by March 31, 2000.

            This letter shall be governed by and construed in accordance with
the laws of the State of New York, without regard to principles of conflict of
laws.

   As representative of the
   several Underwriters

Re: HealthGate Data Corp.

   o  Shares of Common Stock

Dear Sirs:

      This is to confirm that prior to our execution and delivery of a lock-up
agreement addressed to you dated June __, 1999, HealthGate Data Corp., a
Delaware corporation (the "Company"), has informed us that in connection with a
lock-up agreement between Barry M. Manuel and SG Cowen Securities Corporation,
as a representative of the several underwriters ("SG Cowen"), Dr. Manuel will be
permitted to transfer up to 20,000 shares of the Company's Common Stock as bona
fide gifts to individuals or entities, and, such transferee(s) shall not be
bound by the terms of this letter, without violating the term of his lock-up
agreement with SG Cowen.

      This letter is to confirm that the exemption of Dr. Manuel's 20,000 shares
of Company Common Stock as described above shall be deemed not to constitute a
release of Dr. Manuel's shares as described in the final sentence of the third
paragraph of our lock-up agreement with you. Accordingly, Dr. Manuel's transfer
of up to 20,000 shares of Company Common Stock, as described above, will not
require the release of an equal number of shares from the lock-up provision in
our lock-up agreement with you.

                   Re:   HealthGate Data Corp.

Ladies and Gentlemen:

      We have acted as counsel to HealthGate Data Corp., a Delaware corporation
(the "Company"), in connection with (i) the Development and Distribution
Agreement, dated as of June 11, 1999 (the "Distribution Agreement"), by and
between the Company and GE Medical Systems ("GEMS"), a division of General
Electric Company, a New York corporation ("GE"), and (ii) a Warrant Purchase
Agreement, dated as of June 11, 1999 (the "Warrant Purchase Agreement"), by and
between the Company and GE providing for, inter alia, the issuance of a Warrant
(the "Warrant") to GE for up to 300,000 shares of the Company's common stock
(the "Warrant Shares"). This opinion is being furnished to you pursuant to
Section 2.2(i) of the Warrant Purchase Agreement. Terms used herein without
definition shall have the meanings ascribed to them in the Warrant Purchase
Agreement.

      We have examined the originals or certified, conformed or reproduction
copies of all such records, agreements, instruments and documents as we have
deemed relevant or necessary as the basis for the opinions hereinafter
expressed. In all such examinations, we have assumed the genuineness of all
signatures on original or certified copies and the conformity to original or
certified copies of all copies submitted to us as conformed or reproduction
copies. As to various questions of fact relevant to our opinion, we have relied
upon statements or certificates of public officials, officers or representatives
of the Company and others.

Based upon the foregoing, we are of the opinion that:

      1.    The Company is a corporation duly organized, validly existing and in
            good standing under the laws of the State of Delaware and has full
            corporate power and authority to conduct its business as presently
            conducted, to enter into and perform the Distribution Agreement, the
            Warrant Purchase Agreement, the Warrant and the Registration
            Agreement, and to carry out the transactions contemplated thereby.
            The Company is duly qualified to do business and is in good standing
            in the Commonwealth of Massachusetts, the only United States
            jurisdiction in which, to our knowledge, the Company currently owns
            property or conducts its business.

      2.    The authorized capital stock of the Company consists of 20,000,000
            shares of Common Stock, par value $.01 (the "Common Stock"), of
            which 1,151,895 shares are issued and outstanding, and 834,629
            shares of Preferred Stock, par value $.01 (the "Preferred Stock"),
            1,000 shares of which are designated "Series A Convertible Preferred
            Stock," all of which are issued and outstanding, 1,000 shares of
            which are designated "Series B Convertible Stock," all of which are
            issued and outstanding, 1,000 shares of which are designated "Series
            C Convertible Preferred Stock," all of which are issued and
            outstanding, 1,667 of which are designated "Series D Convertible
            Preferred Stock," all of which are issued and outstanding, and
            829,962 of which are designated "Series E Redeemable Convertible
            Preferred Stock," 720,757 of which are issued and outstanding. There
            are no authorized classes of capital stock of the Company other than
            those set forth in this paragraph. All of the issued and outstanding
            shares of capital stock of the Company have been duly authorized and
            validly issued and are fully paid and non-assessable. Except as
            contemplated by the Warrant Purchase Agreement or the Company's
            Amended and Restated Certificate of Incorporation, as amended, and
            except as set forth on Schedule 5.2 to the Warrant Purchase
            Agreement, to our knowledge, (i) no ------------ subscription,
            warrant, option, convertible security or other right (contingent or
            otherwise) to purchase or acquire any shares of capital stock of the
            Company is authorized or outstanding, (ii) there is not any
            commitment of the Company to issue any subscription, warrant,
            option, convertible security or other such right or to issue or
            distribute to holders of any shares of the Company's capital stock
            any evidences of indebtedness or assets of the Company, and (iii)
            the Company has no obligation (contingent or otherwise) to purchase,
            redeem or otherwise acquire any shares of its capital stock or any
            interest therein or to pay any dividend or make any other
            distribution in respect thereof.

            default under, the Amended and Restated Certificate of Incorporation
            or Bylaws of the Company, each as amended to date, or any material
            indenture, lease, agreement or other instrument known to us to which

            exempt, from registration under the Securities Act of 1933, as
            amended.

      We express no opinion as to compliance with applicable anti-fraud
provisions of federal securities laws. We express no opinion as to compliance
with applicable state securities laws.

      The opinions expressed herein are subject to the effect of generally
applicable rules of law that: (a) limit or affect the enforcement of provisions
of any contract that purport to require a waiver of the obligations of good
faith and fair dealing; (b) provide that forum selection clauses are not
necessarily binding on the courts in the forum selected; (c) limit the
enforceability of waivers of the right to trial by jury or rights to notice or
other rights or benefits conferred by operation of law; (d) limit the
availability of a remedy where another remedy has been elected or limit waivers
of remedies or defenses; (e) limit the enforceability of provisions releasing,
exculpating or exempting a party from, or requiring indemnification of a party
for, liability for its own action or inaction or on public policy grounds; (f)
where less than all of a contract may be unenforceable, limit the enforceability
of the balance of such contract to circumstances in which the unenforceable
portion is not an essential part of the agreed upon exchange under such
contract; and (g) govern and afford judicial discretion regarding the
entitlement to attorneys' fees and other costs.

      The opinions on enforceability expressed herein are subject further to the
effect of applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium or other laws affecting the rights of creditors and
secured parties generally, and by general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law), as well
as possible limitations upon the exercise of remedial or procedural provisions
contained in the Distribution Agreement, the Warrant Purchase Agreement, the
Agreement Concerning Stockholders Agreement or the Registration Agreement,
provided, that such limitations do not, in our opinion, subject to the other
qualifications contained in this opinion letter, make the remedies and
procedures that will be afforded to GEMS or GE inadequate for the practical
realization of the principal benefits purported to be provided to GEMS or GE by
the Distribution Agreement, the Warrant Purchase Agreement, the Agreement
Concerning Stockholders Agreement and the Registration Agreement (subject to the
effect of any judicial or other delays in the availability of such remedies).
Notwithstanding the foregoing, however, we express no opinion as to the
enforceability of Section 6 of the Registration Agreement.

      Whenever our opinion with respect to the existence or absence of facts is
indicated to be based on our knowledge or awareness, we are referring to the
actual knowledge or awareness of Rich, May, Bilodeau & Flaherty, P.C. attorneys
who have given substantive attention to such matters during the course of such
representation, which knowledge or awareness has been obtained by such attorneys
in their capacity as such and is intended to signify that in the course of such
representation, no information has come to their attention which has given them
actual knowledge or awareness of the existence or absence of such facts, and
that we have undertaken

no independent investigation either within our firm, with our clients, or with
any other person to determine the existence or absence of such facts.

      We are members of the bar of the Commonwealth of Massachusetts and do not
hold ourselves out as competent to opine as to matters of law governed by other
states. Accordingly, our opinions are limited to the laws of the Commonwealth of
Massachusetts, the General Corporation Law of the State of Delaware, and the
laws of the federal government of the United States. To the extent that any of
the laws of New York or other laws govern any of the matters as to which we
express an opinion herein, we have assumed, with your permission, that the law
of such jurisdiction is, in all material respects, the same as that of the law
of the Commonwealth of Massachusetts.

      This opinion is rendered only to the addressees and is solely for their
benefit in connection with the transactions contemplated by the Warrant Purchase
Agreement, and may not be relied upon by any other person for any purpose
without the prior written consent of the undersigned.

                                     Very truly yours,

THIS AGREEMENT is effective as of 1st January 2000, by and between HealthGate
Data Corp., a Delaware corporation ("HealthGate"), having an address at 25

WHEREAS, the Publisher is the owner and publisher of journals and the Publisher
desires to retain HealthGate to maintain, develop and host an on-line World Wide
Web ("Web") site for Content (as defined in SCHEDULE A attached hereto) relating
to its journals;


WHEREAS, HealthGate, among other business activities, hosts and distributes
health, biomedical and scientific Content for publishers through the Internet
using its activePress service;


NOW THEREFORE, in consideration of the foregoing, the mutual promises set forth
in this Agreement and for other good and valuable consideration, the receipt and
adequacy of which is acknowledged by all parties, the parties hereby agree as
follows:


1.       SITE.

         HealthGate shall design, develop, and mount the Content on servers and
         host the Content on a Web site with the address of
         http://www.blackwell-synergy.com (the "Site"). In establishing the
         Site, HealthGate shall (i) mount the Content on its Hardware (as
         defined in Section 7), (ii) make the Content and portions thereof
         accessible in an online interactive mode for searching, access, review,
         displaying in a Web browser or on computer terminals, downloading, and
         printing on users' Web-enabled computer equipment.


2.       SITE SERVICE PLAN.

         The Site Service Plan set forth in SCHEDULE B attached hereto contains
         service and support specifications, including agreed communication
         procedures for the notification and rectification of service errors.


3.       CONTENT MAINTENANCE PLAN.

         The Content Maintenance Plan set forth in SCHEDULE C attached hereto
         contains details, procedures and specifications for posting Content to
         the Site, including agreed processing objectives and communication
         policies for handling error reports.


4.       SOFTWARE MAINTENANCE AND DEVELOPMENT PLAN.

         HealthGate has developed, licensed or otherwise acquired software to
         operate the Site (collectively the "Software"). The Software
         Maintenance Plan attached hereto contains details and descriptions of
         the Software's functions and features and procedures for making minor
         enhancements to the Software. HealthGate agrees to have Section 3 of
         Schedule D implemented and approved by the Publisher by the effective
         date of the agreement. The other sections of Schedule D shall be
         implemented by HealthGate by the dates set out in the relevant sections
         of Schedule D. Notwithstanding the foregoing, the Publisher may elect
         to request the development of additional functions or features not
         described in the Software Maintenance Plan. The fee for such
         development described in Section 11 (e) is based upon the amount of
         labor time (measured in hours) required by HealthGate to evaluate,
         create and test each request.


5.       PROJECT MANAGERS.

<PAGE>


         Both parties agree to name two Project Managers, who shall be
         responsible for arranging all meetings, visits, and consultations
         between the parties, for the transmission and receipt of technical
         information between the parties, and for coordinating any agreed
         implementations.


                  HealthGate: Paul Harman, Roberta Pokigo


                  Publisher: Ian Bannerman, Alan Bacon


         All contact between HealthGate and the Publisher regarding the Site,
         Content, Software and implementation and maintenance shall be
         coordinated between the Project Managers. Either party may substitute
         other individuals as Project Manager from time to time upon written
         notice to the other party.


6.       CONTENT AND SOFTWARE BACK-UP.

         The Publisher shall provide all Content, including text and graphics,
         for the Site. The Publisher, at its expense, shall deliver the Content
         in electronic format to HealthGate as specified in the Content
         Maintenance Plan. As set forth in Section 20 below, the Publisher
         retains all ownership and copyrights of the Content. HealthGate will
         not make or permit any changes to the Content without the written
         consent of the Publisher. HealthGate shall make and maintain back-up
         copies of all Content and Software pursuant to a schedule set forth in
         the Site Service Plan. HealthGate shall store said back-up materials in
         a commercially reasonable safe and secure environment and not located
         at the same location as the Hardware.


7.       SERVER HARDWARE AND EQUIPMENT.

         HealthGate shall maintain the Site on HealthGate's Web server and/or
         other servers through the Term of this Agreement. HealthGate shall
         acquire and maintain all necessary equipment and hardware (collectively
         the "Hardware") for the Site. The Hardware shall be capable of storing
         the Content. HealthGate shall replace and upgrade, as needed, the
         Hardware so that users of the Site may access the Site approximately 24
         hours per day and receive information from the Site at speeds and
         response times substantially equivalent to HealthGate's own Web site,
         located at www.healthgate.com, from the United Kingdom.


8.       SALES OF INFORMATION.

         The Site will include functions to facilitate the sale of information,
         such as articles, issues and subscriptions, to users of the Site via a
         secure server to non-subscribers of the Content. The Publisher shall
         establish all fees ("Information Fees") and other terms and conditions
         for such sales. HealthGate shall collect the Information Fees
         established by the Publisher. Within 60 days of the end of each
         calendar month, HealthGate shall forward to the Publisher the net
         Information Fees actually collected, which shall be equal to the
         Information Fees less a Processing Fee for each sale which shall be
         retained by HealthGate. The Processing Fee is further described in
         Section 11 (f).


9.       ACTIVITY REPORTS.

         During the time that HealthGate hosts the Site, HealthGate shall
         provide to the Publisher activity reports detailing performance, access

         agreement.

10.      ADVERTISING.

         The Site shall be designed to include space for advertising. All
         specifications concerning advertising space shall be determined by
         mutual agreement of the Publisher and HealthGate. HealthGate shall use
         the activePress advertising module to host, update, and administer
         advertising banners on the site. The parties shall share the right to
         sell advertising banners on the Site, but all advertising is subject to
         prior review and approval by the Publisher, which approval shall not be
         unreasonably withheld. Revenues from advertisers shall be allocated
         between both parties as described in Section 11 (g) below.


11.      SCHEDULE OF FEES.

         (a)      SITE MAINTENANCE. The Publisher shall remit to HealthGate
                  $145,000 annually for Site maintenance services outlined in
                  the Site Service Plan.

         (b)      CONTENT CONVERSION. The Publisher shall remit to HealthGate an
                  annual fee of $346,500 for converting for release via the Site
                  the Content which shall comprise up to 210 individual journal
                  titles. This fee shall apply whether or not the Publisher
                  supplies HealthGate with Content for 210 individual journal
                  titles. If the Publisher supplies HealthGate with Content from
                  more than 210 individual titles the Publisher shall remit to
                  HealthGate an annual fee of $1650 for each additional
                  individual journal title of the Content converted for release
                  via the Site. If content for a particular additional title is
                  not loaded in the first half of the year (i.e. it is not
                  loaded in the period January through June) and, instead, is
                  introduced for the first time and loaded in the second half of
                  the year (i.e. it is loaded in the period July through
                  December) the annual fee in the year it is first loaded shall
                  be $1000. Further, if the Publisher chooses to supply Content
                  from journal titles in excess of the initial 210 and these
                  additional titles shall be in the form of bibliographic
                  headers and PDF files only, then the annual conversion fee
                  shall be $1450.

                  Content Conversion fees will be reviewed by mutual agreement
                  each quarter to take account of potential savings as a result
                  of changes in working methods. For example, the content
                  conversion fees could be reduced if the publisher supplies
                  full-text content in XML.

         (c)      CONTENT STORAGE. The Publisher shall remit to HealthGate an
                  annual fee of $123,000 for 200 gigabytes of storage of the
                  Content on the Hardware. After one year the Publisher and
                  HealthGate will meet and review the requirement for additional
                  storage. The annual fee that the Publisher will pay HealthGate
                  for additional storage shall be no greater than $600 for each
                  additional gigabyte of storage of the Content on the Hardware
                  in excess of 200 gigabytes of storage.

         (d)      SOFTWARE MAINTENANCE. The Publisher shall remit to HealthGate
                  an annual license fee of $191,000 fee for maintaining the
                  Software as described in the Software Maintenance Plan. This
                  fee includes an allowance of 48 working days (equivalent to
                  384 hours) of development labor time per year for HealthGate
                  to make minor changes to the Software as requested by the
                  Publisher and agreed to by HealthGate, whose agreement shall
                  not be unreasonably withheld.

         (e)      SOFTWARE DEVELOPMENT. The Publisher shall remit to HealthGate
                  a fee of $1,200 for each 8 hours of labor time used for the

                  in the Software Maintenance Plan.

         (f)      PROCESSING FEE. The Publisher shall remit a Processing Fee, as
                  described in Section 8 above, equal to 25% of each Information

                  shall be equal to $4.00 per sales transaction processed by

                  subscription are not subject to a processing fee.

         (g)      ADVERTISING. Each party shall receive 30% of the gross
                  advertising revenue for advertising sales on the Site (as

                  subject to minimum fees of $10 per thousand impressions and
                  $100 per page per month.

         (h)      RE-SUPPLY AND RE-WORK OF CONTENT. The Publisher may re-supply
                  SGML Content and request HealthGate to convert it again for
                  release via the Site. The Publisher will use its best efforts
                  to re-supply less than 25 issues per month. The Publisher
                  shall remit to HealthGate a fee of $100 for each re-supplied
                  issue of a journal title per month in excess of 25 issues per
                  month for which the Publisher requests HealthGate to convert
                  again for release via the Site, subject to a maximum of $5,000
                  per financial quarter. The Publisher can re-supply for
                  conversion a particular issue to HealthGate up to a maximum of
                  two times. If an issue is re-supplied more than two times, the
                  Publisher shall remit to HealthGate a fee of $100 for each
                  additional re-supply of the issue. The Project Managers of
                  both parties can meet and agree to waive or adjust the
                  re-supply fee in exceptional circumstances, such as one where
                  the Publisher may request a systematic change to Content.

         (i)      ACTIVITY REPORTS. All payments and fees described in Section
                  11 (f) shall be based upon the relevant activity reports

         Any failure by HealthGate in meeting the throughput processing

         constitute a breach of this agreement and be subject to the procedure
         for termination as defined in Section 17 (b). Further, if HealthGate
         fails to process the Content of any journal issue within the processing
         objective time of 3 working days, as described in Schedule C,
         HealthGate, recognizing the loss caused to the Publisher, will on

         $2,000 per issue, subject to a maximum of $50,000 per financial
         quarter, for all issues processed in each financial quarter.


         Such sums of money will be paid by HealthGate to the Publisher not as a
         penalty, but as and for the ascertained and liquidated damages owing
         and payable by HealthGate to the Publisher by reason of such failure to
         meet the processing objectives.


14.      DISTRIBUTION RIGHTS.

         The Publisher grants to HealthGate the right to sell individual
         articles and subscriptions to the Content through HealthGate's own Web

         parties for this activity.

15.      INITIAL TERM.

         The Initial Term of this Agreement shall commence on the date first
         noted above and, unless terminated earlier as set forth herein, shall
         continue for a period of two (2) years after such date (the "Initial
         Term").

         beginning 120 days before the end of the Initial Term and for each
         subsequent annual term.


17.      TERMINATION.

         (a)      END OF TERM. Either party may terminate this Agreement upon
                  the last date of the Initial Term or any subsequent renewal
                  term by giving written notice of termination to the other
                  party no later than ninety (90) days prior to the end of the
                  Initial Term or of any subsequent one year term.


         (b)      BREACH. Either party may terminate this Agreement by giving
                  written notice of termination to the other party if that party

                  Agreement and fails to remedy such breach within thirty (30)
                  days of receipt of such notice.

         (c)      CHANGE OF CONTROL OF HEALTHGATE. The Publisher may terminate
                  this Agreement by giving written notice of termination to
                  HealthGate if there is a change in control of HealthGate. For
                  the purpose of this section, a person shall have "Control" of
                  HealthGate if he holds, directly or indirectly, shares which
                  together with shares held by any persons acting in concert
                  with him carry 50% or more of the voting rights of HealthGate
                  and is a direct competitor of the Publisher. For the purpose
                  of this section, a "direct competitor" shall be defined as a
                  company that derives more than 50% of its sales revenues from
                  the activity of publishing scientific, technical and medical
                  journals.

         (d)      BANKRUPTCY. Either party may terminate this agreement if the
                  other party shall commit any act of bankruptcy, shall have a
                  receiving order made against it, shall make or negotiate for
                  any composition or arrangement with or assignment for the
                  benefit of its creditors or if the other party, being a body
                  corporate, shall present a petition or have a petition
                  presented by a creditor for its winding up or shall enter into
                  any liquidation (other than for the purposes of reconstruction
                  or amalgamation), shall call any meeting of its creditors,
                  shall have a receiver of all or any of its undertakings or
                  assets appointed, shall be deemed by virtue of the relevant
                  statutory provisions under the applicable law to be unable to
                  pay its debts, or shall cease to carry on business.


         Upon the termination of this Agreement, HealthGate or its personal
         representative as the case may be, shall immediately deliver up to the
         Publisher all correspondence, reports, documents, specifications,
         papers, information (on whatever media) and property belonging to the
         Publisher which may be in his possession or under his control together
         with all confidential information or copyright works belonging to the
         Publisher. HealthGate shall erase the Content from its servers and
         otherwise discontinue any use of the content within ten (10) working
         days of the date of the termination.

         In the event of termination of this Agreement by the Publisher pursuant
         to Section 17, the Publisher will have the following rights and

         and to facilitate the orderly transfer of responsibility for the Site
         to the Publisher or a successor provider of the Site designated by the
         Publisher. The Publisher agrees to pay HealthGate fees for services
         associated with the transition. The rate and amount of such payment

                  faith, to ensure a mutually satisfactory license of the
                  Software to the Publisher or, at the Publisher's option, to a
                  replacement contractor. The period of liaison will commence as
                  soon as notice has been given of termination of this
                  Agreement, and will continue for a maximum period of 3 months
                  after termination;

         (b)      HealthGate agrees that at the time of termination of this
                  Agreement, it will render all assistance, provide all
                  documentation and undertake all actions to the extent
                  necessary to effect an orderly assumption of the Site by the
                  Publisher or, at the Publisher's option, by a replacement
                  contractor;

         (c)      If the Publisher so require, HealthGate will use its best
                  endeavours to procure the transfer at the Publisher's expense,
                  to the Publisher or to a third party nominated by the
                  Publisher at the Publisher's sole discretion, of any Third
                  Party Software licenses HealthGate may have obtained in its
                  own name in order to run the Site and used for that purpose
                  exclusively;

         (d)      HealthGate will develop, together with the Publisher, a plan
                  for the orderly transition of services ("Transition Plan")
                  then being performed by HealthGate from HealthGate to the
                  Publisher or such successor provider.

         (e)      HealthGate will provide reasonable training for personnel of
                  the Publisher in the performance of the services then being
                  transitioned to the Publisher or such successor provider of
                  Services


19.      POST TERMINATION SUPPORT IN THE EVENT OF BANKRUPTCY


         In the event of termination of this Agreement by the Publisher as a
         result of HealthGate committing an act of bankruptcy as set forth in
         17(d) and for a period of six (6) months thereafter, HealthGate will
         provide the Termination Support set forth in Section 18 herein. In
         addition, HealthGate will continue to perform, for a reasonable period
         (as determined by the Publisher) of up to six (6) months following the
         termination date, any or all of the services then being performed by
         HealthGate.


         In the event of HealthGate committing an act of bankruptcy as set
         forth in 17(d), the Publisher agrees to pay HealthGate fees for
         services associated with the transition. The rate and amount of such
         payment shall be determined by both parties agreeing to meet and use

                  shall take appropriate action by instruction or agreement with
                  its employees who are permitted access to the HealthGate
                  Confidential Information or any copy or other physical
                  embodiment thereof in any media in its possession, to satisfy
                  its obligations hereunder. Promptly upon discovery that any
                  person has acquired possession, use or knowledge of any part
                  of the HealthGate Confidential Information other than as
                  authorized by this Agreement, the Publisher shall notify
                  HealthGate of such fact and the surrounding circumstances. The
                  obligations of this Section 20(c) shall survive any
                  termination of this Agreement. The obligations of this Section
                  20(c) shall not apply to any information which (a) is
                  generally known to the public, or becomes so known other than

                  hereunder, (b) was known to the Publisher prior to its
                  disclosure by HealthGate, or (c) is learned by the Publisher
                  from a third party who is not in breach of an obligation of
                  confidentiality in making such disclosure.

         (d)      PUBLISHER'S CONFIDENTIAL INFORMATION. HealthGate understands

                  compiling, manipulating, presenting and disseminating
                  information which is disclosed to HealthGate (collectively,
                  "Publisher's Confidential Information"), represent valuable
                  confidential information of the Publisher entitled to
                  protection as trade secrets. HealthGate shall keep
                  confidential, and shall protect from unauthorized disclosure
                  by its employees and agents, the Publisher's Confidential

                  Confidential Information to those of its personnel and
                  personnel of its consultants or agents who require such access
                  in connection with HealthGate's use thereof as permitted by
                  this Agreement. HealthGate shall secure and protect the
                  Publisher's Confidential Information and any and all copies
                  and other physical embodiments thereof in its possession in a
                  manner consistent with the maintenance of the Publisher 's
                  rights and interest therein. HealthGate shall take appropriate
                  action by instruction or agreement with its employees, agents

                  embodiment thereof, to satisfy HealthGate's obligations
                  hereunder. Promptly upon discovery that any person has
                  acquired possession, use or knowledge of any part of the
                  Publisher's Confidential Information other than as authorized
                  by this Agreement, HealthGate shall notify the Publisher of
                  such fact and the surrounding circumstances. The

                  20 (d) shall not apply to any information which (a) is
                  generally known to the public, or becomes so known other than

                  that the other party may timely present its objections to such
                  disclosure, each party shall provide the other party with
                  timely notice of a request, requirement or demand to disclose
                  such information or matter which is either made by a public

Schedule B - Site Service Plan
- --------------------------------------------------------------------------------

1. Hardware and communication resources

The Hardware to host the Site shall be located at HealthGate's computer
facilities currently housed at Exodus Communications, Inc. Internet Data Center,
located in Waltham, Massachusetts, USA.

1.1 Site access

HealthGate shall maintain adequate Internet access via telecommunications to the
Site so that users of the Site may access the Site approximately 24 hours per
day, and receive information from the Site at speeds and response times
substantially equivalent or superior to HealthGate's own Web sites.

1.2 Software maintenance downtime

In order to maintain and update the Software, HealthGate schedules regular
downtime on Saturdays from 10.00 PM to 12.00 Midnight, US Eastern Time. Although
this downtime is scheduled every week the Site would probably only be down once
a month because the maintenance needs are not frequent. Where possible, during
the actual downtime the Site will display a page so that users accessing the
Site will be aware of the situation.

In order that HealthGate may fulfil it contractual obligations with regard to
maintenance of the Software, it may be necessary to schedule time when the Site
may be unavailable. In these cases, the Project Managers of both parties shall
mutually agree upon a time, at least 3 working days in advance, of when the site
will be unavailable.

1.3 Site monitoring

HealthGate's principal business activities rely upon uninterrupted Internet
access and, consequently, will use its best endeavours to ensure that the
Publisher's Site receives the best possible service. HealthGate remotely
monitors the Home Page of the Site every 60 seconds. If, for any reason, the
server does not respond, the redundant server switches in automatically to serve
the Site and a paging message is sent to HealthGate's duty staff member. Within
15 minutes of receiving the paged message, this staff member will check that the
redundant machine has correctly switched in within 15 minutes. If this process
fails, the duty staff member will restart the server remotely. If this is also
unsuccessful, the duty staff member will post a notice to users on the Site Home
Page and will contact other team members to ensure the Site is made available to
users as soon as possible.

In addition, a browser page on the server monitors the links to the database
tables every 180 seconds. If, for any reason, the links are defective a paging
message is sent to HealthGate's duty staff member and a similar procedure is
followed.

1.4 Site server hardware

The Site server is configured with two machines - one as live server, one as
redundant back up. If one machine ceases to operate, the redundant machine
automatically switches to serve the Site and a paging message is sent to
HealthGate's duty staff member. The storage device holding the Content has a
capacity of 200 gigabytes, but may be expanded to at least 400 gigabytes. Stored
data is backed up once every 24 hours and copies of back-up tapes are held off
site.

1.5 Proxy serving in the United Kingdom

HealthGate will arrange for a caching proxy server with approximately 50
gigabytes of usable cache to be hosted in the United Kingdom. This device will
hold some elements of the Site and should enable United Kingdom users accessing
Content on the Site to receive a faster service. It will also enable the Site to
use a United Kingdom Primary Domain Name.

2. Communication procedures

2.1 User support

The Help section of the User Interface of the Software contains telephone
numbers and an e-mail address to enable users to contact the customer support
service at HealthGate. The telephone support service shall be operational 8.00
AM to 6.00 PM, US Eastern Time, and shall be supported by voice mail at other
times. All e-mails sent to the support address shall be acknowledged within one
working day of receipt - for the purposes of this clause, the usual working days
are Monday to Friday from 09.00 AM to 5.00 PM, US Eastern Time, except in the
case of US National Holidays taken by HealthGate.

2.2 Publisher support

HealthGate will supply and update information to the Publisher Project Managers
to enable them to contact via telephone, telephone pager or e-mail either the
HealthGate Project Managers or HealthGate's Hardware operation duty staff at any
time during the week. Access exceptions may be mutually pre-notified and
mutually agreed in advance to take account of US National Holidays. The
telephone support service shall be operational 3.00 AM to 10.00 PM, US Eastern
Time, and shall be supported by voice mail at other times. All e-mails sent to
the support address shall be acknowledged within one working day of receipt.

2.3 Periodic meetings of Project Managers

Both parties will agree upon a fixed schedule of dates and locations of Project
Manager meetings for each year of the agreement. The principal purpose of these
meetings is to enable the Project Managers to discuss matters of mutual interest
with regard to any matters pertaining to the Agreement. At least one Project
Manager from each party will attend each meeting. In advance of such meetings
either party may elect to nominate additional employees to attend, subject to
the other party's approval. With respect to sickness or any other cause, either
party may request to postpone or cancel a meeting provided that the other party
is given reasonable notice of such a request and approval of such a request
shall not be unreasonably withheld.

2.4 Training arrangements

The Publisher retains remote control of the Site through the Publisher
Interface. In order for the Publisher's authorised staff to be able to manage
the Site efficiently and effectively one of HealthGate's Project Managers will
provide 2 days of training per year at the Publisher's main business location.
The Publisher can request HealthGate for additional training days and these may
be billed to the Publisher at a mutually agreed rate.

2.5 Changes to the Hardware

HealthGate shall supply with the Publisher with a graphical overview of the
Hardware installation. Each time that HealthGate makes a significant change to
the Hardware, the Publisher will be notified and supplied with an updated
graphical overview.

Schedule C - Content Maintenance Plan
- --------------------------------------------------------------------------------

1. Content conversion and enhancement

1.1 Receipt of content

The Publisher shall notify HealthGate by e-mail of new Content transferred via
FTP. The message will contain the following information: Journal code, Volume
number, Issue number, Number of files and file types (SGML, GIF and PDF files)
and Comments or Notes.

Upon receipt of this e-mail HealthGate will move the data into directories for
initial pre-processing staging. A master archive copy of all content is also
made. Any obvious gaps or errors will be reported to the Publisher.

1.2 Content conversion

The SGML text files are initially converted to HealthGate's Extensible Markup
Language (XML) format. HealthGate also produces a thumbnail version of each GIF
image scaled to an agreed standard. The Publisher may take on this conversion
step to give the Publisher greater flexibility. Mathematical formulae supplied
within SGML files in the AMS-LaTeX format are converted into GIF files or other
formats suitable for Web viewing. HealthGate and the Publisher will mutually
agree on future enhancements for the conversion and display of mathematical
formulae.

1.3 Content enhancement

The XML files are then parsed to add more information that may include either
tags to link each article's bibliographic references to references within other
bibliographic databases or tags to link to other articles within the Site. The
links for each journal title will be agreed by the Publisher and HealthGate.
Reciprocal linking between the Site and other bibliographic databases to
specific journal titles will be mutually agreed.

1.4 Error reporting

HealthGate will immediately notify the Publisher by e-mail, within two (2)
business days, of any content that is adjudged to be either incomplete or
defective in any other way such e-mail shall note the journal name, volume,
issue and article ID(s). In these cases, the Publisher will advise HealthGate
whether or not to process the issue. The Publisher will either re-supply the
complete issue or the defective components and the Publisher and HealthGate will
mutually agree the revised production timeframe for these issues on a
case-by-case basis.

1.5 Processing objectives

HealthGate's objective for processing the Content comprising a new journal issue
is 3 working days. This throughput time objective is defined as (a) starting
from the moment that all files comprising the new issue are supplied to
HealthGate and received by HealthGate in a full and complete format; and (b)
completing the moment that the new issue is moved to a mutually-agreed and
defined staging area on the Site. HealthGate's operating capacity for processing
the Publisher's Content is 30 issues per working day. This throughput time
objective does not apply in any of the following circumstances:

o     If the Publisher requests HealthGate by e-mail to process particular
      issues in advance of issues already supplied (such requests can only be
      accepted by e-mail from an authorised employee of HealthGate)

o     If any of the Content comprising an issue is incomplete or incorrectly
      supplied

o     If the volume of Content supplied exceeds HealthGate's operating capacity
      - in this case HealthGate's capacity defines the throughput time

o     If Content for new titles is supplied - the standard for these is
      specifically addressed in Section 3 of this Schedule.

1.6 Monitoring and reporting

HealthGate will, throughout the production processes defined above, provide
regular, timely and accurate reports to the Publisher. HealthGate will work
towards the creation of an automated production monitoring system and will
provide the Publisher with access to information from the system regarding the
conversion status of a particular issue, article or object.

<PAGE>

Schedule C - Content Maintenance Plan
- --------------------------------------------------------------------------------

1.7 Fully automated content processing

HealthGate will work towards the creation of a fully automatic process to
convert and load Content onto the live Site. Such a process will, if feasible,
be designed to pull files from the Publisher's FTP site. This system could also
be enhanced by mutual agreement between HealthGate and the Publisher to achieve
three other features: (a) to enable the Publisher to re-supply individual files
(GIF, PDF and SGML) so that these items are automatically re-integrated into the
issue; (b) to permit individual articles to be loaded independent of an issue
being available; and, (c) the generation of an e-mail message to the Publisher
that confirms receipt of files pulled from the FTP server.

HealthGate will enable the fully automated content processes to take account of
the Digital Object Identifier (DOI) or other non-bibliographic based
identifiers. Publisher and HealthGate will mutually agree the definition of such
identifiers.

Schedule C - Content Maintenance Plan
- --------------------------------------------------------------------------------

2. Content staging and release

2.1 Database loading

As soon as all the content from a particular journal issue is processed it is
loaded in the content repository database. Database records are made of each
article's bibliographic details (title, authors, article type, category, volume,
issue and pages) from which Tables of Contents are generated. HealthGate sends
an e-mail to the Publisher alerting the appropriate personnel that the issue is
available for review. Authorised employees of the Publisher are then able to see
the issue for proofing, but access is restricted to all others.

2.2 Content approval and release

The content will appear in the User Interface part of the Software. The
authorised employees of the Publisher can then review the content and decide
whether or not to release a journal issue for general user access. The "For Sale
Y/N" field of the Publisher Interface part of the Software can be used to
exclude general access to view the issue to enable the Publisher to review the
material on-line prior to releasing it. The database also includes fields for
copyright notices and other notices of right title and interest to the content
and these fields can also be adjusted using the Publisher Interface part of the
Software.

2.3 Error reporting

If any employee of the Publisher determines that content is missing, incomplete
or displaying incorrectly, an authorised employee of the Publisher will send an
e-mail to HealthGate clearly defining the problem. In appropriate cases, they
will also examine the original source files to determine if errors occurred in
the source material.

2.4 Table of Contents (TOC) e-mail

The action of changing the For Sale Y/N field of the Publisher Interface part of
the Software from N to Y will generate the distribution by e-mail of the journal
issue's TOC to those users that have requested receipt of TOC e-mails in the
User Interface part of the Software.

Schedule C - Content Maintenance Plan
- --------------------------------------------------------------------------------

3 New titles

3.1 Set-up

From time to time the Publisher might wish to include a new journal title in the
Site. At such a time the Publisher must send HealthGate via e-mail details
regarding the title and a banner GIF file to be displayed in the User Interface
of the Software. These details should include at least the following
information:

ISSN Paper; ISSN Electronic; Journal Name; Journal Abbreviation Code; Copyright
Line, Pricing information. The Publisher will provide all of this information at
the same time.

In addition, the Publisher could supply the MEDLINE Abbreviation; Database names
for external linking (including provision for HealthGate's access rights);
Society Name; Society Code; URL on the Publisher's own site(s); Subject
Group(s); and Document Type Definition (DTD).

HealthGate will use this information to do two things: (a) adapt the filter, if
necessary, for converting content from SGML into HealthGate's internal format;
and (b) set up the title in the user interface. If HealthGate receives content
for a new journal title without the necessary header information, their first
action will be to request the details.

3.2 Lead time for new titles

HealthGate will load the first issue of a new title within 10 working days of
full and complete data being supplied by the Publisher. Any such new title shall
be supplied in a previously agreed upon DTD. Where any new title taken on from a
Society has existing electronic files available (i.e. not produced by the
Publisher), the conversion and loading of these files will be subject to
evaluation and discussion by HealthGate and the Publisher.

Schedule D - Software Maintenance Plan
- --------------------------------------------------------------------------------

1. User Interface Description

The User Interface is constructed with a number of pages using Microsoft's
active server page (asp) tools. Each page is described below. Many of the pages
are directly linked to one another and most also have a navigation menu bar to
enable a user to browse through the pages efficiently and effectively. Unless
otherwise noted, all functionality described in this Schedule D which is not
available on the Effective Date of this Agreement shall be delivered as
released, but no later than 31 March 2000.

1.1 Home Page

The Home Page contains links to the following pages User Registration, User
Login, List of Journals and About.

1.2 User Registration

Registration: The user provides demographic information and selects a user name
and password.

User name creation: User names are unique and are allocated on a
first-come-first-served basis.

Confirmation of registration: Upon successful completion of registration, the
user receives an e-mail acknowledging their registration. Maintenance and
management of User names for the site is independent of Maintenance and
management of User names for HealthGate's other sites. During user registration,
the e-mail address entered will be compared with those on file. If the e-mail
address has already been used, the user is prompted with the choice of
continuing or receiving an e-mail of the username and password for the existing
account. The purpose is to stop multiple registrations from users that have
forgotten their passwords.

During registration the user will have the option of having a cookie stored on
their local machine to facilitate auto login.

1.3 User Login

In order to access many areas of the Site users must identify and authenticate
themselves against their User Name. Users can Login from the Home Page, but are
also referred to the Login page when attempting to access sections of the site
that require authentication.

Users enter their particular User Name and Password on the Login page.
Successful authentication passes the user either to their personal page ("Your
Home Page") or to the relevant page from which they were referred.

The page also contains a mechanism for the user to look up and find their
password without contacting customer support. The user inputs their User name or
e-mail address and the user database is searched for a match. If there is a
match, the user is asked if they wish to receive an e-mail sent to the e-mail
address associated with the User Name. If there is not a match, the user should
send an e-mail to or telephone the customer support service.

Once the user has successfully logged in, the user's name details will display
on subsequent pages.

If the user's Auto Login cookie is detected on the Site homepage, the user will
be automatically authenticated and taken to their Personal Homepage. Any pages
requiring authentication will also check the Auto Login cookie before prompting
for login.

1.4 List of Journals

This page contains a list of journal titles, sorted by Publisher, that have
issues available on line. Each title is linked to a page that lists all issues
available on line and the table of contents of the current issue. This page will
contain an "A-Z" bar to navigate to journal titles alphabetically. This page
will link to other pages listing the journals by different groupings: "All
Journals", "Journals by Publisher" and "Subject Groups".

1.5 About

The About Page is designed by the Publisher and contains general information
about the Site. The About page may link to other flat HTML pages that will be
supplied by the Publisher, or created using the HTML editor.

1.6 Your Home Page

This page is personal for each User Name. It contains information regarding a
user's current subscription and article purchases; a list of titles for which a
TOC e-mail has been selected; a listing of the user's

Schedule D - Software Maintenance Plan
- --------------------------------------------------------------------------------

saved searches; a link to a page listing journal titles for which the user may
select to receive a TOC e-mail and a link to a page containing links to
favourite articles and journals as defined by the user.

The page also has a link to an associated page - the Update User Registration
page. An authenticated user can change demographic details such as e-mail
address, password and postal address. Other options available from Your Home
Page include the facility to input an Offer Code, an Access Token and select any
personal preferences for customisation of the site.

The page has an area for displaying a message to a particular group of users as
defined in the Publisher Interface. Groups will include all subscribers to a
named journal and all users that have entered an Offer Code. Other users will
see a default message.

The Personal Homepage has a link to allow personal users on a machine with an
unrecognised institutional IP address to write the auto login cookie to the
machine's hard disk.

1.7 Table of Contents (TOC) e-mail Selection

On this page a user may select (or de-select) one or several titles for which
they want to receive a TOC e-mail. If users choose this feature, they will be
sent the new table of contents for each journal for which they have selected the
service. This feature is available to non-subscribing users as well as
subscribers. The format of the TOC e-mail will be defined by the publisher and
will contain a URL linking directly to the abstract of each article listed.

1.8 Simple Search

In order to perform a search a user is required to authenticate by going through
the Login page. The Simple Search form enables a user to search the database of
bibliographic records for each article accessible on the site. The fields
include: Author Last Name(s), Author Initial(s), Article Title, Journal Title,
Keywords, Year, Volume and Issue and Full text search. The search can be
restricted to (a) All journals, (b) Only favourite journals as defined by the
user (from Your Home Page list), (c) a single journal, (d) journals in a
selected subject group as defined in the Publisher Interface. The user will have
a choice to rank search results by publication date or relevancy.

1.9 Advanced Search

The advanced search form allows the user to perform a Standard Boolean fielded
search. The user can combine fielded search terms with other terms through
operators to include AND, OR and NOT. Wildcards can also be used to refine the
search. The search can be restricted to (a) All journals, (b) Favourite journals
as defined by the user (from Your Home Page list), (c) a selected journal, (d)
journals in a selected subject group as defined in the Publisher Interface. The
user will have a choice to rank search results by publication date or relevancy.
The advanced search can be further restricted to (a) all issues, (b) issues
published in the last 1,3,6,9 or 12 months, (c) between 2 specified dates.

The Publisher and HealthGate will mutually agree to the design of the search
form which will include some field names as well as a free-text field.

1.10 Search Results

The search results page lists article title information where the search
criteria are matched. The results are ordered by relevancy or publication date.
Where ordered by relevancy each item will display a percentage relevancy
ranking. Each item in the list of search results will have a check box. The user
may select one or more articles by checking the boxes and then view the
abstracts sequentially on a single page. Each abstract will contain links to the
Full Text and PDF article.

The user can select a name for the search and save the search criteria. The
Saved Search can be re-run from a link on the Personal Homepage. The user can
perform a new search or return to the simple or advanced page to refine the
search criteria.

1.11 List of Issues

This page lists the issues for a particular title that are currently available
on line. Each issue in the list is linked to its TOC. Some issues may be tagged
as "Free Samples" and these are available for registered and authenticated users
to view without charge.

A link is created on this page to take the user to the appropriate journal home
page of the Publisher's own site. A text field will allow a user to search for a
word in the keywords or abstract from that journal. Searching requires
authentication, so an unauthenticated user will be asked to login before the
search results are displayed.

Schedule D - Software Maintenance Plan
- --------------------------------------------------------------------------------

A button allows a user to add the journal to their list of favourites displayed
on Your Home Page.

Design will make provision for the inclusion of an indivdual GIF illustration
file associated with each issue.

The Publisher will have the ability to supply tables of contents for future
issues through the Publisher Interface. These future tables of contents will be
available to users via the List of Issues page. When a new issue goes live, the
new interactive table of contents will replace the flat one.

Users will be able to link directly to the table of contents for a particular
issue using an inbound URL resolver.

The List of Issues page will contain a link to the latest issue and a defined
number of recent issues. Older issues will be accessible via links to issues
published within a given year (e.g. links to "1999 Issues", "1998 Issues"). The
Publisher and HealthGate will agree upon a list of the journal titles for which
to create Tables of Contents and abstracts (where available) for previous years'
material. The data for creating these Tables of Contents will be loaded from
third party databases, such as MEDLINE. The content type will be indicated as
"Full text", "Abstracts" or "Bibliographic Data Only".

1.12 Table of Contents

This page lists all articles and other material (such as editorials, reviews and
correspondence) that constitute the issue grouped by article category and then
in page number order. Each article listed contains the title and primary
author(s) as well as page numbers. Each article could potentially be linked to
its Abstract, Full Text or PDF page and to supplementary material. The size of
the PDF file will be indicated adjacent to the PDF button.

Generally, access to Abstracts is provided free of charge, but access to
Full-Text and PDF is limited to users who have obtained subscription or document
delivery privileges.

A text field will allow a user to search for a word in the keywords or abstract
from that issue. Searching requires authentication, so an unauthenticated user
will be asked to login before the search results are displayed.

A link will be included to a page that lists, in alphabetical order, authors of
papers in the issue. The author names will be linked to the abstract, full text
or PDF of the articles.

Page design will make provision for the inclusion of an indivdual GIF
illustration file associated with each issue.

1.13 Abstract

This page contains the abstract and a link to the Full Text and PDF. It also
contains a link to the Notify A Colleague e-mail page. If Supplementary Material
is available and tags are provided in the source SGML, an icon will link to it
from this page.

The page will display a link to the MEDLINE record of the current article, if
such a record exists in MEDLINE. Similar links to the record of the current
article in other databases will also be included by mutual agreement between
HealthGate and the Publisher.

A button allows a user to add the abstract to their list of favourites displayed
on Your Home Page

1.14 Full Text

This page displays the Article in an HTML format. A user must have already
purchased a subscription to the particular Journal Title or purchased the
specific article before being passed to this page (except in the case of a Free
Sample issue). If a user does not validate on access to the page, a purchase an
offer page will be presented enabling the user to purchase a subscription or
article delivery on-line.

All references and figures within the body of the text are linked to the list of
references at the end of the Article or to the figure page. All references that
have links to predefined databases, such as MEDLINE, are linked to those
references. Figures and tables are referenced and linked to respective full page
displays. If Supplementary Material is available and tags are provided in the
source SGML, an icon will link to it from this page. In addition, authors of the
article are tagged to external (predefined) databases searches as are keywords
listed. Author and keyword searches to predefined databases, such as MEDLINE,
are linked to an intermediary page giving the users the opportunity to refine
these searches.

The page will display a link to the MEDLINE record of the current article, if
such a record exists in MEDLINE. Similar links to the record of the current
article in other databases will also be included by mutual agreement between

1.15 Maths

Mathematical formulae supplied as AMS-LaTeX are converted by HealthGate into GIF
format files for Web viewing. In the future, as part of development, delivery in
other formats such as LaTeX or a change to the Publisher's DTD to incorporate
the MathML standard will be mutually agreed by both parties and tested to the
satisfaction of both.

1.16 References

The references are currently present at the end of the main text file.
References may be presented in pop-up windows. This would permit selective
presentation of only relevant references. This also obviates the need to return
to the 'parent' file when viewing a citation within an object window. As an
example, if the article cites [1,2-5,8,9], the pop-up will include only these
refs. This pop-up window may be dynamically generated to facilitate linking to
standard databases.

1.17 Object Windows

As for the Full Text Section, but the dimensions will be specified by the
Publisher. Treatment of object windows as a pop-up will permit the user to
compare two or more figures, or to refer to the text.

1.18 Graphics

Graphics files will be available to the user in the most suitable format the
browser can use: Shock Wave Flash if enabled, GIF if not. In the future the
Publisher and HealthGate may mutually agree to the supply and use of additional
file formats, such as high resolution JPEG.

1.19 Supplementary Material

Supplementary Material (which may consist of textual, tabular, graphical, video,
audio or animated data), will be made available free of charge via an icon on
the Table of Contents and accessible from within the full text. Links to the
material will be will be supplied by the Publisher in the source SGML.

Links to helper applications will be included as necessary.

The data will be supplied by the Publisher. If the Publisher requests HealthGate
to convert the material and host it, HealthGate will charge the Publisher the
full costs associated with conversion.

1.20 Multiple-part documents

HealthGate and the Publisher will mutually agree on a specification for handling
Multiple-part documents.

1.21 Multiple-Abstract sections

HealthGate and the Publisher will mutually agree on a specification for handling
Multiple Abstract sections.

1.22 PDF

This page downloads the Article in a PDF file. A user must have already
purchased a subscription to the particular Journal Title or purchased the
specific article before being passed to this page (except in the case of a Free
Sample issue). If a user does not validate on access to the page, a purchase
offer page will be presented enabling the user to purchase a subscription or
article delivery on-line.

The size of the PDF file will be indicated adjacent to the PDF button used to
access the file.

In order to view the downloaded article, the user must obtain a copy of Adobe
Acrobat Reader. A link to Adobe's Home Page is available on the Help Page.

1.23 Notify a Colleague

This feature enables an authenticated user to send an e-mail to an acquaintance
that contains URL information and a link to an abstract or article. A user
completes the destination e-mail address or addresses and can then add their own
comments to the e-mail prior to sending it.

1.24 Purchase Offer Page

This page contains the offers available for a user to purchase. It could contain
various purchase offers as follows Article, Regular Subscription and Discounted
Society Subscription. These offers could be listed in a variety of different
currencies.

User selection of an offer links to the secure Credit Card connection page.

The Publisher Interface can used to control the layout of this page on a title
by title basis. One or more of the following may be displayed for each title:
(a) document delivery offer, (b) subscription offer in one or more currencies,
(c) standard text including link to Publisher's web-site and (d) a piece of HTML
text for each journal entered with an HTML editor from the Publisher Interface.

1.25 Credit Card Validation

Once the offer has been selected, the user will then be shown a page that
provides a secure connection for credit card information. The user will be asked
to give the credit card number, type (VISA, MasterCard, AMEX, Discover), and
expiration date.

The credit card is then validated and the user is shown the cost that has been
charged to the credit card. A unique receipt number is displayed on the page and
a copy is e-mailed to the e-mail address supplied by the user during
registration.

1.26 Society Membership Validation and Offer Code

The Publisher can supply lists of names and membership numbers of learned
societies. In this way registered users can verify their society membership and
incorporate these details as part of their User Profiles.

A link to this validation page is contained within Your Home Page. A user
selects the Offer Code link and inputs a code relevant to a particular society
offer - this code is supplied to the society member by the Publisher. The user
then inputs the validation information - usually Surname and Membership number.

A society offer may include free on-line subscriptions to one or more titles or
special discounts to titles. Once the society membership information is
validated these offers are presented to the user - free subscriptions are
automatically listed on Your Home Page. A choice of offers may be made
available, such as selecting one or more titles from a package. Upon selecting
an offer the user will be taken to the credit card validation page. Upon
successfully completing the transaction, the subscriptions will be added to Your
Home Page.

If a user successfully validates society membership, but does not, at the same
time, take up an offer that requires payment, the offer will be presented on the
Purchase Offer page when the user subsequently tries to access content covered
by the offer.

1.27 Publisher Access Tokens

The Publisher can accept subscription orders from users off-line and would wish
users to validate them on-line. The Publisher may also wish to provide free
access to users such as editorial board members. The Publisher interface
contains a tool to generate Access Tokens. These Tokens can cover single or
multiple titles and the Publisher can define their expiry date. Each token can
only be used once.

A user supplied with a Token links to the Access Token validation page from Your
Home Page. The Token is input and the subscription is linked to that User Name
or Institutional Name.

1.28 Help

The Help page contains e-mail and telephone contact details for users to submit
their queries to. It also contains linked URL's for Microsoft and Netscape
browser and for the Adobe Acrobat Reader software downloads. The help page can
be edited and linked to newly created pages via the Publisher Interface. To
standardise the communication routes and to facilitate the direction of queries
to the relevant HealthGate and Publisher e-mail addresses a help form will be
designed by the Publisher. This form will enable a user to send e-mail from
their browser. The user will enter their e-mail address (defaulted if an
authenticated personal user), name, subject and free text message. The user will
be able to choose from a number of categories to be defined by the Publisher,
such as "subscription queries", "technical problems", and "other queries". The
user has the option of sending themselves a copy of the mail. The mail is routed
to a pre-defined e-mail address for each category of query. The body of the
e-mail will contain header information including (where known) username, e-mail
address, name, subject, browser type and version being used, IP address, time

The Publisher will design a similar form so that users can send feedback to the
Publisher.

1.29 Menu Bar

The Menu Bar can be included on any page as defined by the Publisher and it can
display different elements according to the page it displays on. The elements
that can be included are links to the following: Home Page, Your Home Page, List
of Journals, List of Issues, Table of Contents, Notify A Colleague, Search and
Help.

1.30 Access to the MEDLINE database

HealthGate hosts the MEDLINE database under licence from the US National Library
of Medicine. The references of full-text of articles from some journals will be
linked to their specific MEDLINE record. In addition, the interface contains a
link to a MEDLINE search form. This search form will be HealthGate's Advanced
Search Form. A user can use the form to enter a query against the MEDLINE
database. If records are found that match the query this displays as a hit list.
A user may then select to view the abstract of a particular record from the hit
list. The abstract display will also include (where available):

Related articles

The related articles of a specific abstract are those abstracts in the MEDLINE
database that are the most similar to it. The similarity between documents is
measured by the words they have in common with some adjustment for abstract
lengths.

Link to full text of an abstract

When a MEDLINE abstract contains a link to the full-text of an article, a button
will display in the abstract display. This button links to the Web site
belonging to the publishing copyright owner of the journal where the full text
article resides. These publisher Web sites may require a subscription or fee in
order to view the full-text of an article.

The user will be able to view the abstract in both MEDLINE and bibliographic
citation manager formats and be able to save the abstract in MAC, PC or UNIX
format as either text or HTML.

1.31 Linking from other databases

The Publisher will supply some third party database hosts with a resolver that
permits users of these databases to link into the Site using the bibliographic
details supplied by the Publisher to the third party. A user of a third party
database will gain access to the Site as follows - (a) if the user is recognised
by the Site (by valid IP address, previous session login or auto-login cookie)
and has access rights to the content, the user will gain access the to the
Abstract, PDF, or Full Text as determined by the referring resolver; or (b) if
the user's access rights cannot be recognised, the user will be presented with a
page to either login or register and, if the login is successful, the user will
gain access to the Abstract, PDF, or Full Text as determined by the referring
resolver.

1.32 Reciprocal linking to other publisher on-line systems

By reciprocal agreement with other publishers, the Publisher will supply
HealthGate with bibliographic citations that are linked directly to other third
party on-line systems. The Publisher will then permit users referred from these
third party sites to view full-text files without the requirement to
authenticate. Where possible, this type of relationship will take into account
Forward Linking, so that each time such a link is generated, the linked-to
publisher is notified and can append a forward link to the cited file.

1.33 Forward Linking

When each new intra-Synergy link is created, the article that has been
referenced will have added to it a 'Forward link'. These will be listed at the
bottom of the article under a section headed "Articles citing this work". For
each link, the following information will be displayed: Authors (surnames,
initials), year, article title, publication title, volume number and page range.

1.34 Toll Free Links

o     Where one of the Publisher's articles refers to another article available
      on the Site, a user with access rights to the article containing the
      reference will be able to follow the reference link to the full text of
      the article cited without requiring access rights to the cited article.

o     Where a Toll free Linking agreement exists between the Publisher and a
      third party, users with access rights to an article on the Site can also
      link to an article hosted by the third party without requiring access
      rights. This may be achieved by embedding a code in the referring URL.
o     Where a Toll free Linking agreement exists between the Publisher and a
      third party, users with access rights to an article on the third party
      site can link to an article hosted on the Site without requiring access
      rights. This may be achieved by embedding a code in the referring URL.
o     Free access is only available to the article referred to - not all
      articles in that issue or journal.

2. Publisher Interface

The overall purpose of the Publisher Interface is twofold - (a) to provide the
Publisher with as much control as is feasible (at the detail level) of its own
titles; and (b) to enable the Publisher to know as much as possible about its
users.

The Publisher has secure access to these functions and authorises employees
accordingly. Much of the information contained within parts of this interface is
used to deliver dynamic details to the User Interface pages. In general the
information can be changed on a real-time basis by the Publisher, thus affecting
the real-time information on the User Interface.

There will be two levels of access rights. One level permits access to just the
Access Token generator and the other level permits access to all other parts of
the interface. The Publisher will be issued with a "master" access right that
can create Publisher access accounts - each access account could have access to
one or both levels of access.

2.1 Journal Information

The procedure to set-up new journals and their initial entry into the system is
initiated by the Publisher. The authorised Publisher employee enters all
applicable information for a new Title such as the title name, copyright
statement and ISSN. The interface also permits the Publisher to remove the title
from sale. The Publisher can also assign a journal to be part of one or more
Subject Groups.

2.2 Issue Information

As a new issue is processed and loaded for delivery to the User Interface pages,
information about the issue populates a database. The information includes
Volume Number, Issue Number, Publication Date, Issue Date, Number of Pages, URL,
For Sale Y/N, Banner GIF and Free Sample Y/N.

2.3 Article Information

Each article loaded in the database contains associated information - the record
fields include Unique Article ID, Issue, Article Name, Page Start, Page End,
Abstract URL, Article URL and PDF URL.

2.4 SKUs and Offers

Each journal title can be sold to users as a time-based subscription and
individual articles of the title can be sold individually. The SKU and Offer
section of the Publisher Interface enables the Publisher to enter combinations
of prices, currencies and time of access for each title at both a subscription
and article level. The prices can also be tied to Society Membership validation
so that Society Offers can be created and later redeemed at the User Interface.

2.5 Societies and Membership lists

This component of the interface enables the Publisher to set up a new society
and upload membership validation details.

Each society has associated with it a code which users input on the Offer Code
part of Your Home Page. Membership lists are uploaded into the database for
corresponding society codes. The validation mechanism checks that a user is
inputting the correct surname associated with the membership number.

The Publisher interface component enables the Publisher to refresh or amend
membership details and, used in conjunction, with the SKU/Offer part permits
special journal subscription prices to be offered to society members. The
membership number and last name can also be amended.

The Publisher Interface allows updated membership data to be checked against the
existing records on file for uniqueness. Duplicates will be reported in an
agreed format.

The Publisher Interface allows the Publisher to generate reports of usernames
and registration details as follows:
(a) society members loaded for a particular offer code
(b) society members that have validated their membership on the Site
(c) society members that have not validated their membership on the Site
(d) validated society members that haven taken up an offer requiring payment

2.6 Access Token Generation

This page contains a list of journal titles that are available for sale. The
Publisher can select one or more titles and generate one or more access tokens.
The page enables the Publisher to set the expiry date of the subscription
associated with the token and also include an associated reference number.

The Publisher can select to either (a) output the Access Token to the browser
page, or (b) have the titles automatically added to a registered user's account
by specifying a valid User Name.

2.7 User Demographic Information

Each registered user has associated with it the following demographic
information: Title, First Name, Last Name, Honours, E-Mail Address, Username,
Password, Country, Job Title, Company/Institution, Department, Phone, Fax,
Street Number, Street, City/Town, State/Province/County, Post/ZIP Code, VAT
Registered?, VAT Registration Number and area of professional responsibility
(dropdown or free text).

2.8 HTML editor

HealthGate will supply the Publisher with an HTML editor. This editor can be
used by the Publisher to insert HTML text at fixed positions within the
following pages of the Site:
Home Page
List of Journals Page
List of Issues Page
Table of Contents Page
Your Home Page
Table of Contents E-Mail Selection Page
Registration Pages
Society Membership Validation Pages
Access Token Input and Confirmation Pages
Search Pages
Help

Each of these pages may contain one or more areas of customisable text.
Publisher and HealthGate will mutually agree the positions within each page that
maybe customisable. The Publisher is responsible for the text and/or wording for
these pages.

2.9 Table of Contents (TOC) e-mail Messages

This component of the interface enables the Publisher to add a message to the
TOC e-mails for particular journals. This message can be issue specific or
time-based.

2.10 Subject Groups

The Publisher Interface allows the Publisher to create, edit and delete Subject
Groups. The Publisher assigns a name for the Subject Group to be displayed on
the subject list area of the List of Journals page. A journal can be assigned to
one or more subject groups. These subject groupings can also be specified as
filters when searching.

2.11 Institutional Activation

This component of the interface enables the Publisher to generate an Activation
Code for use by an administrator of an institutional user name. The Publisher
enters the institution name and an Activation Code is generated The Publisher
can then assign journal subscriptions to the account by selecting journal titles
and expiration dates. The Publisher then supplies the Activation Code to the
Institutional Administrator.

Upon receipt, the Institutional Administrator enters the Activation Code to set
up their Administrator Homepage.

The Publisher can edit administrator information and check the activation status
and entry date for a particular Activation Code.

The Publisher can search for a record by Activation Code, institution name or
other fields completed by the administrator on activation. The Publisher can
generate reports based on this activation information.

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

3. Institutional Access Interface

The Publisher sells bundles of subscriptions to a wide variety of institutions.
Members of these institutions require access to the subscriptions purchased on
their behalf, but the institutions do not want their members to be authenticated
in the same way as individual users - they want access privileges to be granted
according to IP address. However, institutions may also wish to supply a User
Name and Password for their members to access their subscriptions when these
member are away from their physical site.

The institutions also maintain journal holding information for subscriptions
purchased from a wide-variety of other sources and will likely build links
directly to the list of issues pages for each title. All parts of this Section 3
shall be delivered by 31 December 1999.

3.1 IP address validation

Each page of the site as described above will be sensitive to the user's
referring IP address. If a user comes in from a recognised IP address, the name
of the institution (as defined by an institutional administrator during
activation) is displayed on each page.

3.2 Institutional List of Journals

A page will display the list of titles purchased by the institution. Users can
then link to issues, tables of contents, full text and PDF articles without
being prompted to login. A link will also allow institutional users to access a
full list of all journals. Users attempting to access the full text of PDF
article from a title that the institution does not subscribe will be given the
choice of logging in as a personal user, or purchasing through document
delivery. The Institutional List of Journals page also allows users to login as
personal users, or register as personal users.

3.3 Table Maintenance of IP valid addresses

Each institution will be issued with an Activation Code. A designated
institutional administrator will enter this number to activate their
institution's subscriptions. The administrator is required to enter contact
details and choose an administrator username and password. The administrator can
then enter the IP addresses, and IP ranges for that institution. The
administrator can login at any time with the administrator username and
password. The administrator pages will allow the administrator to (a) edit the
IP addresses, (b) update contact information, (c) create and delete
institutional passwords and (d) generate and download pre-defined usage reports
for that institution.

3.4 Institutional Password Access

Members of an institution accessing via an IP address that is not recognised by
the system can login as either a personal user with a personal username and
password, or as an institutional user with an institutional username and
password. The Institutional Administrator can create institutional username and
passwords for distribution to off-site users through the administrator pages. On
entering a valid institutional username and password, users are taken to the
institutional list of journals with the institution name displayed on the page.
All other activities during that session are identical to those for a user that
has been IP validated.

3.5 Moving Between Institutional and Personal States

Validated institutional users (whether via a recognised IP address or a valid
institutional password) can change state to "personal user" by clicking the
"Your Homepage" link. After logging in, the usual personal homepage will be
displayed, with the addition of an extra link to "Institutional List of
Journals". This link allows the user to change state back to "institutional" and
will authenticate the user (IP or institutional username and password) and take
the user to the Institutional List of Journals.

3.6 Direct Access

Institutions will be able to gain direct access to the list of issues for each
title by following URL links from other library resources. When accessing the
list of issues, the institution name will be displayed on the page if the IP
address was recognised. When a user attempts to access the full text or PDF
article an IP check will be carried out to verify access rights for this
account. If the IP address is not recognised, the

user is prompted to login. After successfully authenticating, the user will
either be granted access or be presented with a variety of offers.

                                   ARTICLE 12
                             NONDISCLOSURE AGREEMENT

12.1.    HealthStream expressly undertakes to retain in confidence all
         information and know-how transmitted to HealthStream by HealthGate that
         HealthGate has identified as being proprietary and/or confidential or
         that, by the nature of the circumstances surrounding the disclosure,
         ought in good faith to be treated as proprietary and/or confidential,
         and will make no use of such information and know-how except under the
         terms and during the existence of this Agreement. HealthStream shall
         not disclose, disseminate or distribute any such confidential
         information or know how to any third party without HealthGate's prior
         written consent. HealthStream agrees to use the same degree of care to
         protect HealthGate confidential information as HealthStream takes to
         protect its own confidential information of like importance. However,
         HealthStream shall have no obligation to maintain the confidentiality
         of information that:

         12.1.1.  Is received rightfully from another party prior to its receipt
                  from HealthGate;

         12.1.2.  HealthGate has disclosed to a third party without any
                  obligation to maintain such information in

<PAGE>


                  confidence; or

         12.1.3.  Has been or is independently developed by HealthStream.

12.2.    Further, HealthStream may disclose confidential information as required
         by governmental or judicial order, provided HealthStream gives
         HealthGate prompt notice of such order and complies with any
         confidentiality or protective order (or equivalent) imposed on such
         disclosure. HealthStream shall treat the terms and conditions of this
         Agreement as confidential; however, HealthStream may disclose such
         information in confidence to its immediate legal and financial
         consultants as required in the ordinary course of HealthStream's
         business. HealthStream's obligation under this Article 12 shall extend
         to the earlier of such time as the information protected hereby is in
         the public domain through no fault of HealthStream or five (5) years
         following termination or expiration of this Agreement. HealthStream
         shall not disclose any information on HealthGate's unannounced products
         to HealthStream's employees or any third party.

12.3.    HealthGate shall have the same obligations in Sections 12.1 and 12.2
         above with respect to HealthStream's information and know-how. In
         addition, HealthGate shall treat all T.NAV(R) materials (including
         source code if obtained) as confidential information and shall not
         disclose, disseminate, or distribute such materials to any third party
         without HealthStream's prior written permission.

12.4.    Both parties shall prepare a mutually acceptable press release, if any,
         to announce this Agreement.

                                     AUDITS

13.1.    During the term of this Agreement, the parties hereto agree to keep all
         usual and proper records and books of account and all usual and proper
         entries relating to Transactions and sales of Ad Inventory consistent
         with generally accepted accounting principles.

13.2.    HealthStream may cause an audit to be made of the applicable HealthGate
         records that pertain to this Agreement for the sole purpose of
         verifying royalty reports issued by HealthGate to HealthStream and
         prompt adjustment shall be made to compensate for any errors or
         omissions disclosed by such audit. Any such audit shall be conducted by
         an independent certified public accountant of national stature (E.G.,
         Deloitte) selected by HealthStream (other than on a contingent fee
         basis) and shall be conducted during regular business hours at
         HealthGate's offices and in such a manner as not to interfere with
         HealthGate's normal business activities. Any such audit shall occur no
         more than once per calendar year and within six (6) months of the end
         of the calendar year. HealthStream shall pay for any such audit unless
         Material discrepancies are disclosed. "Material" shall mean the lesser
         of Five Thousand Dollars (US$5,000.00) or five percent (5%) of the
         amount that should have been reported. If Material discrepancies are
         disclosed, HealthGate agrees to pay HealthStream the costs associated
         with the audit not to exceed Five Thousand Dollars (US$5,000.00). The
         auditor shall only disclose the correct data and amounts as called for
         on the royalty reports.

13.3.    HealthGate may cause an audit to be made of the applicable HealthStream
         records and facilities for the sole purpose of verifying any reports
         issued by HealthStream to HealthGate, and prompt adjustment shall be
         made to compensate for any errors or omissions disclosed by such audit.
         Any such audit shall be conducted by an independent certified public
         accountant of national stature (E.G., Deloitte) selected by HealthGate
         (other than on a contingent fee basis) and shall be conducted during
         regular business hours at HealthStream's offices and in such a manner
         as not to interfere with HealthStream's normal business activities. Any
         such audit shall be paid for by HealthGate unless Material
         discrepancies are disclosed. "Material" shall mean the lesser of Five
         Thousand Dollars (US$5,000.00) or five percent (5%) of the amount that
         should have been reported. If Material discrepancies are disclosed,
         HealthStream agrees to pay HealthGate for the costs associated with the
         audit not to exceed Five Thousand Dollars (US$5,000.00). In no event
         shall audits be made more frequently than annually unless the
         immediately preceding audit

<PAGE>


         disclosed a Material discrepancy. The auditor shall only disclose the
         correct data and amounts as called for on the royalty reports.

13.4.    Any statement shall affect neither the right to examine and audit nor
         the right to receive an adjustment to the contrary, appearing on checks
         or otherwise, unless expressly agreed to in writing by the party having
         such right.

13.5.    In the event that either party makes any claim with respect to an
         audit, upon the audited party's written request the party who has
         requested such audit will make available to the audited party the
         records and reports pertaining to such audit prepared by the
         independent auditor who performed such audit.

     any time if in HealthGate's sole judgment such use is not consistent with

     to Licensee or the HealthGate Products of any rights in or to any
     HealthGate Trademark, except for the limited rights expressly granted under

     Licensee. Accordingly, any use by HealthGate of the Licensee Trademarks
     pursuant to this Agreement, shall be subject to Licensee's approval, which
     Licensee may deny or revoke at any time if in Licensee's sole judgment such
     use is not consistent with the goodwill otherwise associated with the
     Licensee Trademarks. Neither this Agreement nor any rights granted
     hereunder will operate as a transfer to HealthGate of any rights in or to

9. WARRANTY, INDEMNIFICATION AND LIMITATION OF WARRANTIES AND LIABILITY

9.1 WARRANTY.


     9.1.1 HealthGate warrants to Licensee that it has the full legal right to
           grant the license granted under this Agreement. HealthGate warrants
           to Licensee that the HealthGate Products, in the forms delivered to
           Licensee by HealthGate and when properly used for the purpose and in
           the manner specifically authorized by this Agreement do not infringe
           upon any patent, copyright, or trademark and do not misappropriate a
           trade secret or other proprietary right of any person. To the extent
           HealthGate has received a warranty of title from a Licensor with
           respect to any specific intellectual property, HealthGate hereby
           warrants to Licensee that it or its licensor has title to such
           intellectual property only.


     9.1.2 HealthGate warrants to Licensee that for a period of ninety (90) days
           from the date of delivery of the HealthGate Products or an upgrade
           thereto to Licensee that the HealthGate Products shall substantially
           perform in accordance with Licensee's specifications; provided,
           however, that any ninety (90) day warranty period for an update shall
           only apply to that update and not to the HealthGate Product otherwise
           existing as of the date of the upgrade. Licensee's sole and exclusive
           remedy for breach of this warranty shall be for HealthGate to modify
           or correct the HealthGate Products. This warranty shall not apply to
           any HealthGate Product which has been modified by Licensee or by any
           other party other than HealthGate, or which has been used in any
           other manner other than as authorized under this Agreement.

     9.1.3 With respect to the development services provided in Section 2.3,
           HealthGate warrants to Licensee


<PAGE>

           that any software products delivered to Licensee are not capable of
           permitting any of the following: (1) unauthorized access to or
           intrusion upon; (2) disabling of; (3) erasure of; or (4) interference
           with any hardware, software, data or peripheral equipment; provided,
           however, this warranty shall not apply to e-mails, electronic
           transfers, or other database sharing.

     9.1.4 HealthGate expressly warrants that HealthGate Products are currently
           Year 2000 complaint. "Year 2000 compliant is defined to mean
           HealthGate Products accurately and unambiguously process (including,
           but not limited to, compare, calculate, manipulate, sequence,
           display, and exchange data with other systems) data containing time
           and/or dates prior to, at, and after the year 2000 without error or
           interruption, and the products operate properly and in conformance
           with applicable specifications, continuously, before, at, and after
           the year 2000."

     9.1.5 With respect to the development services provided in Section 2.3,
           each of HealthGate's employees, agents or representatives assigned
           to perform services hereunder shall have the proper skill, training
           and background so as to be able to perform in a competent and
           professional manner and all work will be so performed.

9.2  HEALTHGATE INDEMNITY. HealthGate shall defend or settle, at its own
     expense, any cause of action or proceeding brought against Licensee which
     is based on a claim that the use of the Information as provided hereunder
     infringes any patent, copyright, trade secret or other proprietary right.
     HealthGate shall indemnify and hold Licensee harmless against all damages,
     judgments, and attorneys' fees arising out of the foregoing, provided that
     Licensee gives HealthGate prompt written notice of such claim. If a claim
     is made that the use of the Information as provided hereunder infringes any
     patent, copyright, trade secret or other proprietary right, HealthGate
     shall either procure for Licensee the right to continue using the
     Information, modify it to make it non-infringing but continue to meet the
     specifications therefor, or replace it with a similar non-infringing
     content as determined by the sole discretion of HealthGate.

9.3  LICENSEE'S INDEMNIFICATION OBLIGATIONS. Excluding claims arising out of or
     relating to the violation by HealthGate or an Information Partner of any
     third party copyright, trade secrets, or trademark, Licensee, to the extent
     permitted by applicable law, agrees to indemnify HealthGate and its
     Information Partners and hold them harmless from and against any and all
     claims of Licensee, Authorized Users or other third parties arising out of
     or related to the use of the HealthGate Products, the Information or other
     licensed materials, regardless of whether such claims were foreseeable by
     HealthGate or the Information Partner. The provisions of this Section 9.3
     will survive any termination.

9.4 DISCLAIMER OF WARRANTIES, LIMITATION TO WARRANTIES AND LIABILITIES.

       THE WARRANTIES EXPRESSED IN SECTION 9.1 ABOVE REPRESENT THE ENTIRE
       WARRANTY OF HEALTHGATE WITH RESPECT TO THIS AGREEMENT, AND ARE IN LIEU OF
       ANY AND ALL OTHER WARRANTIES, WRITTEN OR ORAL, EXPRESS OR IMPLIED,
       INCLUDING WITHOUT LIMITATION, WARRANTIES OF MERCHANTABILITY OR WARRANTIES
       OF FITNESS FOR A PARTICULAR PURPOSE, ALL OF WHICH HEALTHGATE DISCLAIMS.
       DUE TO THE NUMBER OF SOURCES FROM WHICH INFORMATION ON THE HEALTHGATE
       PRODUCTS IS OR WILL BE OBTAINED, AND THE INHERENT HAZARDS OF ELECTRONIC
       DISTRIBUTION, THERE MAY BE DELAYS, OMISSIONS OR INACCURACIES IN SUCH
       INFORMATION AND THE HEALTHGATE PRODUCTS. THE HEALTHGATE PRODUCTS COULD
       INCLUDE TECHNICAL OR OTHER INACCURACIES OR TYPOGRAPHICAL ERRORS.
       PERIODICALLY, CHANGES MAY BE MADE IN THE INFORMATION PROVIDED IN THE
       HEALTHGATE PRODUCTS. HEALTHGATE AND ITS AFFILIATES, AGENTS AND ITS
       INFORMATION PARTNERS CANNOT AND DO NOT WARRANT THE ACCURACY,
       COMPLETENESS, CURRENTNESS, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
       PURPOSE OF THE INFORMATION AND CONTENT AVAILABLE THROUGH THE HEALTHGATE
       PRODUCTS, OR THE HEALTHGATE PRODUCTS THEMSELVES, OR ANY OTHER INFORMATION
       WHICH IS REFERENCED BY OR LINKED TO THE HEALTHGATE PRODUCTS. THE PRESENCE
       IN OR ABSENCE FROM THE INFORMATION, RELATED MATERIALS, DATA, EVENTS,
       RESEARCH OR DEVELOPMENTS DOES NOT IMPLY THE SPECIFIC EXISTENCE OR THE
       NON-EXISTENCE THEREOF, NOR DOES HEALTHGATE CLAIM COMPREHENSIVENESS OR THE
       ABSENCE OF ERRORS. HEALTHGATE ASSUMES NO RESPONSIBILITY FOR THE USE OF


<PAGE>

       THE HEALTHGATE PRODUCTS BY THE LICENSEE OR AUTHORIZED USERS. HEALTHGATE
       AND ITS INFORMATION PARTNERS SHALL NOT BE LIABLE FOR LOSS OF PROFITS,
       LOSS OF USE, OR INCIDENTAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES AS A
       RESULT OF USE OF THE HEALTHGATE PRODUCTS OR THE INFORMATION, EVEN IF
       EXPRESSLY MADE AWARE OF THE POSSIBILITY THEREOF. EXCEPT FOR ANY CLAIM FOR
       INDEMNITY UNDER SECTION 9.2, IN NO EVENT MAY ANY ACTION BE BROUGHT
       AGAINST HEALTHGATE, OR AN INFORMATION PARTNER ARISING OUT OF THIS
       AGREEMENT MORE THAN ONE YEAR AFTER THE CLAIM OR CAUSE OF ACTION ARISES,
       DETERMINED WITHOUT REGARD TO WHEN THE LICENSEE OR AUTHORIZED USER SHALL
       HAVE LEARNED OF THE ALLEGED DEFECT, INJURY, OR LOSS. IN NO EVENT SHALL
       HEALTHGATE'S LIABILITY UNDER THIS AGREEMENT EXCEED THE AGGREGATE AMOUNT
       OF LICENSE FEES PAID BY LICENSEE PURSUANT TO THIS AGREEMENT (WHETHER SUCH
       LIABILITY ARISES FROM BREACH OF WARRANTY, BREACH OF THIS CONTRACT OR
       OTHERWISE, AND WHETHER IN CONTRACT OR IN TORT, INCLUDING NEGLIGENCE AND
       STRICT LIABILITY). THE PROVISIONS OF THIS SECTION 9.4 SHALL SURVIVE ANY
       TERMINATION OF THIS AGREEMENT.

10. MISCELLANEOUS

10.1   With respect to the development services provided in Section 2.3,
       HealthGate acknowledges that Confidential Information provided by
       Licensee may also be protected by law. HealthGate will neither disclose
       such information, directly or indirectly, nor use such information for
       any purpose except to perform the services described in this Agreement.
       Patient medical and financial files and all documents or records of
       Licensee which may be used or received by HealthGate shall remain
       exclusive property of Licensee.

       Licensee, on behalf of itself and the Affiliated Providers and HPG
       Members, acknowledges that Confidential Information provided by
       HealthGate may also be protected by law. Licensee, the Affiliated
       Providers and HPG Members will neither disclose such information,
       directly or indirectly, nor use such information for any purpose except
       to perform the services described in this Agreement.

       Either party shall take appropriate action, by instruction to or
       agreement with its employees, agents and subcontractors, to maintain the
       confidentiality of the Confidential Information. Either party agrees to
       execute written Confidentiality Agreements with its employees, agents,
       and subcontractors addressing either party's obligations set forth in
       this section. Either party shall promptly notify the other party in the
       event that it learns of any unauthorized release of Confidential
       Information.

       Either party shall have no obligation with respect to:

          (a)  Confidential Information made available to the general public
               without restriction by the other party or by an authorized third
               party;
          (b)  Confidential Information rightfully known to either party
               independently of disclosures by the other party under this
               Agreement;
          (c)  Confidential Information independently developed by either party;
          (d)  Confidential Information that either party may be required to
               disclosure pursuant to subpoena or other lawful process;
               provided, however, that the party notifies the other party in a
               timely manner to allow the other party to appear and protect its
               interests; or
          (e)  Any information regarding any Authorized User of the HealthGate
               Products obtained from or through their use of those products.

        Upon the termination of this Agreement, either party shall:

          (a)  Immediately cease to use the Confidential Information.
          (b)  Return to the other party, Confidential Information and all
               copies thereof within thirty (30) days of the termination or
               destroy the Confidential Information in accordance with the other
               party's policy and all-applicable state and federal laws.
          (c)  Upon request, certify in writing to the other party that it has
               complied with its obligations set forth in this Section.


<PAGE>

        The parties acknowledge that monetary remedies may be inadequate to
        protect their rights with respect to Confidential Information and that,
        in addition to legal remedies otherwise available to either party,
        injunctive relief is an appropriate judicial remedy to protect either
        party's rights in Confidential Information.

        Either party hereby agrees to indemnity and hold harmless the other
        party from and against any and all liability, loss, damage, claims or
        causes of action and expenses associated therewith (including attorney's
        fees) caused directly or indirectly by the party's breach of its
        obligations under this Section 10.1. Either party may enforce the other
        party's obligations hereunder by seeking equitable relief which remedy
        shall be nonexclusive. Either party agrees to provide reasonable
        assistance and cooperation upon the request of the other party in
        connection with any litigation against third parties to protect
        Confidential Information.


10.2 INDEPENDENT CONTRACTOR. HealthGate and Licensee are and shall remain
     independent contractors with respect to all matters pursuant to the
     Agreement.

10.3 ASSIGNMENT. Licensee may sell, transfer, assign, or subcontract, any right,
     license or obligation set forth in this Agreement without the express
     advance written consent of HealthGate; provided, however, Licensee may not

     set forth in this Agreement to Medscape, WebMD, Healtheon, and Dr. Koop or
     any of their successors or assigns.

10.4 AMENDMENTS IN WRITING. No amendment, modification, or waiver of any
     provision of this Agreement shall be effective unless it is set forth in a
     writing that refers to this Agreement and is executed by an authorized
     representative of each party hereto. No failure or delay by any party in
     exercising any right, power, or remedy will operate as a waiver of any such
     right, power, or remedy.

     as provided herein) shall be in writing and shall be deemed to have been
     duly given upon receipt, and shall be either delivered in person, by

                        SNAP STRATEGIC ALLIANCE AGREEMENT

                              HEALTHGATE DATA CORP.

This Strategic Alliance Agreement (the "Agreement") is made and entered into as

liability company, with its principal place of business at One Beach Street, San
Francisco, California 94133 ("Snap"), Xoom.com, Inc., a Delaware corporation
with its principal place of business at 300 Montgomery Street, Suite 300, San
Francisco, California 94104 ("Xoom"), and HealthGate Data Corp., a Delaware
corporation, with its principal place of business at 25 Corporate Drive, Suite
310, Burlington, Massachusetts 01803 (the "Company"). Pursuant to this
Agreement, Snap will provide various services to the Company to assist the
Company in promoting its Internet site and the products and services offered
through its Internet site. Accordingly, the parties hereby agree as follows:

1.       BACKGROUND.

         1.1.     The Company operates an Internet site located at
                  http://www.healthgate.com,which is designed to provide
                  Internet-based personal health and medical information,
                  products and services to online consumers.

                  Web.

         1.3.     Xoom operates a direct marketing site on the Web.

         1.4.     Snap has entered into an Agreement and Plan of Contribution
                  and Merger, dated as of May 9, 1999 with Xoom and others, and
                  the Second Amended and Restated Agreement and Plan of
                  Contribution, Investment and Merger dated as of July 8, 1999
                  with National Broadcasting Company, Inc. ("NBC") and others
                  (collectively, as such agreements may be amended, the "Merger
                  Agreements") pursuant to which the existing businesses of
                  Xoom, Snap and other assets of NBC will be combined to form
                  NBC Internet, Inc. ("NBCi"). The closing of the transactions
                  contemplated by the Merger Agreements is expected to occur
                  prior to December 31, 1999 (the "NBCi Closing"). Following the
                  NBCi Closing, Xoom and Snap may assign their rights and
                  obligations hereunder to NBCi. If the NBCi Closing does not
                  occur, Snap and Xoom shall remain as separate parties under
                  this Agreement, unless this Agreement is terminated by one of
                  the parties as provided herein.

         below shall have the following meanings:

                  viewable on a computer screen at an 800 x 600 pixels
                  resolution when the User first accesses such Web page, without
                  scrolling down to view more of the Web page.

         2.2.     "Anchor Tenant" means a preferred Web content provider whose
                  position is greater in size and prominence than that of any

                  or area of a page.

                           delivered pursuant to this SECTION 3.3 during any of
                           Year One, Year Two or Year Three, then such
                           over-delivery of Impressions, which shall not exceed
                           10% of the total number of Impressions required to be
                           delivered by SECTION 3.3.1 for such year, shall be
                           credited towards satisfaction of the next year's
                           obligations for Snap to deliver Impressions until all
                           obligations through the end of the Term have been
                           fulfilled, after which the Company will pay for any
                           additional Keyword Promotions delivered, with payment
                           to be at Snap's then applicable rate card charges for
                           Keyword Promotions.

                  3.3.4.   CLICK THRU DELIVERY. During the Term, Snap will use
                           reasonable efforts to deliver Click Thrus to the
                           Co-Branded Site or the Company Site.

         3.4.     LINKS; PERFORMANCE STANDARDS. The Company will be responsible
                  for ensuring that each link embedded within a Promotion takes
                  the User to the appropriate area within the Company Site or
                  the Co-Branded Site (other than links to the Health Channel
                  for which Snap will be responsible), and that such sites
                  function with reasonable reliability and in a commercially
                  reasonable manner throughout the Term. In particular, the
                  Company agrees that the Company Site and the Co-Branded Site
                  will comply with the performance standards set forth in
                  EXHIBIT C attached hereto throughout the Term. Any failure by
                  the Company to comply with this Section will be deemed to be a
                  material breach of this Agreement. In the event of such
                  breach, Snap shall be deemed to have delivered Impressions and
                  Click Thrus required to be delivered pursuant to this
                  Agreement on a daily, straight-line, pro-rata basis for the
                  duration of such breach.

         3.5.     BEST OF BREED. During the Term, in the event that Snap, in its
                  reasonable discretion, determines that the Company has failed
                  to maintain the Company Site, Company Content, or the
                  Co-Branded Site as Best of Breed in any material respect, Snap
                  shall have the right to terminate this Agreement in accordance
                  with SECTION 10.2 and shall have the right to remove any
                  deficient Company Content from the Snap Sites and the
                  Co-Branded Site until the Company has corrected such failure.
                  Snap acknowledges that all Company Content and the Company
                  Site are Best of Breed as of the Effective Date.

                           shall be the primary points of contact for inquiries
                           and requests, and each Manager shall provide the
                           other with such information and assistance as may be
                           reasonably requested by the other from time to time.
                           Either party to this Agreement may change its
                           designated Manager by giving the other party written
                           notice of such change.

                           Managers shall discuss the Company's Promotions for

                           quarter's Promotions, the reports provided under
                           SECTION 11, and any other items under this Agreement
                           either Manager wishes to bring to the attention of
                           the other Manager.

4.       ANCHOR TENANCY.

         4.1.     ANCHOR TENANT OF CERTAIN HEALTH CHANNEL CONTENT AREAS. After
                  the Launch Date and during the Term, Snap will feature the
                  Company as the Anchor Tenant within seven of the following
                  nine major content areas within the Health Channel:
                  Alternative Medicine, Drugs & Medications, Diseases &
                  Conditions, Nutrition, Women's Health, Sexual Health, Men's
                  Health, Child & Youth Health and Public Health. The Company
                  shall specify in writing its preference for the seven major
                  content areas in which it wishes to be featured as Anchor
                  Tenant at least thirty days prior to the Launch Date. Snap
                  Product Managers shall determine the major content areas in
                  which the Company shall be featured as the Anchor Tenant.
                  Subject to this SECTION 4, Snap may, in the exercise of its
                  reasonable discretion, make changes to the design and
                  functionality of the Health Channel including, without
                  limitation, the names of major content areas; provided,
                  however, that major content areas similar to, or addressing
                  the general categories listed above shall exist within the
                  Health Channel during the Term. As the Anchor Tenant of seven
                  major content areas of the Health Channel, the Company will
                  receive the most prominent positioning within each of such
                  major content areas. During the Term, there shall be no other
                  Anchor Tenant of any of the seven major content areas of the
                  Health Channel in which the Company is then the Anchor Tenant;
                  provided, however, that other major content areas, content not
                  provided by the Company, subject to the terms of SECTION 3.2,
                  and/or links to other, non-Company sites may exist on the same
                  Web page and elsewhere within the Health Channel. The Company
                  acknowledges that Snap may feature Anchor Tenants other than
                  the Company on any major content area within the Health
                  Channel that is not one of the seven major content areas of
                  the Health Channel in which the Company is the Anchor Tenant.
                  Snap and the Company shall negotiate in good faith to
                  incorporate additional health-related Company content, so long
                  as such content is Best of Breed, within the content areas of
                  the Health Channel in which the Company is not the Anchor
                  Tenant, provided; however, Snap shall not be obligated to
                  negotiate with respect to such Company content if an agreement
                  with Company regarding such Company content would be
                  interpreted or operate to cause Snap to breach any existing
                  contract or agreement between Snap and any other party, or
                  impair the rights of any such contract party pursuant to an
                  existing contract or agreement with Snap. In the event that
                  Snap elects to add new content areas on the Health Channel or
                  elsewhere on the Snap Sites, Snap will in good faith first
                  discuss with the Company obtaining


                                       7
<PAGE>

                  additional health-related Company content, so long as such
                  content is Best of Breed, for such additional new content
                  areas. Snap will not enter into an agreement to add or create
                  new health-related content areas on the Health Channel with
                  another party pursuant to an agreement which is comparable in
                  number of content areas or total consideration to those of
                  this Agreement. On the Health Channel, the Company will have
                  the right to program up to five Health Content Portals, each
                  measuring no larger than approximately 150 x 400 pixels, with
                  relevant content and links to the Company Site. Snap shall
                  have the right, in its sole discretion, to add additional
                  content portals on the Health Channel; provided, however, the
                  Company shall have the right to program one additional Health
                  Content Portal, with the specifications set forth in the
                  foregoing sentence, for each health content portal on the
                  Health Channel greater than three that Snap elects to add in
                  addition to the five Health Content Portals. Company will
                  provide the appropriate Company Content, subject to the
                  reasonable discretion of a Snap Product Manager, for the
                  Health Content Portals. The Snap Product Manager may provide
                  the Company with reasonable assistance to enable the Company
                  to effectively design the Health Content Portals. Subject to
                  this SECTION 4.1, the Snap Product Manager will determine the
                  size and location, and the Look and Feel, of the Health
                  Content Portals; provided, however, that the Health Content
                  Portals will begin Above the Fold within five of the seven
                  major content areas of the Health Channel in which the Company
                  is the Anchor Tenant.

         4.2.     HARVESTING. The Company shall provide Company Content as
                  required herein pursuant to Snap's technical specification
                  policies for harvesting set forth in EXHIBIT D attached hereto
                  (unless otherwise mutually agreed to by the parties), as
                  updated from time to time in Snap's sole discretion. Snap
                  shall have the right, in its sole discretion, to harvest such
                  Company Content in a manner requiring a User of the Snap Sites
                  to "click through" as many as two Web pages within the Snap
                  Sites before the User is transferred to the Company Site or
                  the Co-Branded Site. Harvested Company Content will maintain
                  the Snap Sites' Look and Feel and will include branding for
                  the Company using Company Marks, in such form and placement as
                  a Snap Product Manager shall determine in his or her sole
                  discretion. Harvested Company Content shall not include any
                  Commerce Offering, except at Snap's sole discretion.

         4.3.     INTERNAL PROMOTIONS. Subject to the discretion of a Snap
                  Product Manager, during the Term, Snap shall promote and link
                  the Health Channel within and throughout the Snap Sites.
                  Subject to the discretion of a Snap Product Manager, the
                  Company may receive internal promotional links within relevant
                  sub-areas of the Snap Sites that link to the Co-Branded Site.
                  Such relevant sub-areas may include, without limitation, the
                  following: Shopping, Local, Education, Kids and Family. =
                  Snap, in its sole discretion, has the right to create,
                  maintain or discontinue any of the foregoing sub-areas on the
                  Snap Sites. In addition, Snap may include a link to the Health
                  Channel and/or the Co-Branded Site within issues of Snap Wire,
                  as determined by Snap in its sole discretion.

         4.4.     HOSTING. Snap will host the Health Channel, the Health Content
                  Portals and any Company Content harvested pursuant to SECTION
                  4.2 on its servers (or on servers within its control) and will
                  provide all computer hardware, software and personnel
                  necessary to operate and maintain the Health Channel, the
                  Health Content Portals and any harvested Company Content as
                  functional pages accessible to Users.

         4.5.     ADVERTISING. Snap shall own and have the right to use or sell
                  all of the advertising inventory on the Health Channel and on
                  the Company Content it may harvest. The Company acknowledges
                  that any advertising for and/or links to other sites similar
                  to or in


                                       8
<PAGE>

                  competition with the Company may exist in the Health Channel.
                  Notwithstanding anything in this Agreement to the contrary,
                  any third party content or links may exist on any area of the
                  Health Channel. Moreover, other than as expressly set forth
                  herein, Snap shall have the right to display any third party
                  links, media, banner advertisements, other promotions, and/or
                  paid or unpaid editorial content anywhere on the Snap Sites.

5.       CO-BRANDED SITE.

         5.1.     CO-BRANDED SITE DESCRIBED. The Company will develop the
                  Co-Branded Site in accordance with this SECTION 5 and Snap
                  will provide reasonable assistance in connection therewith.
                  The Co-Branded Site will provide all of the features and
                  functionality provided by, and will perform in a manner
                  substantially identical to, the Company Site, as the Company
                  Site may be updated and enhanced from time to time.

         5.2.     CHANGES. Snap acknowledges that the Company may change the
                  design and functionality of the Company Site from time to
                  time, in which case the design and functionality of the
                  Co-Branded Site will be changed in a similar fashion.
                  Notwithstanding the foregoing, the Company will ensure that
                  the Co-Branded Site at all times maintains the Snap Sites'
                  Look and Feel and will make all changes reasonably suggested
                  by a Snap Product Manager for editorial consistency. Snap
                  agrees that all such changes shall refer to the Look and Feel
                  of the Co-Branded Site and not to Company Content on the
                  Co-Branded Site. Snap shall provide reasonable written notice
                  to the Company prior to modifying the Look and Feel of the
                  Snap Sites.

         5.3.     CO-BRANDING FEATURES. Each page on the Co-Branded Site will
                  include branding for Snap and the Company so that the Snap
                  Marks and Company Marks are both Above the Fold and are of
                  substantially equivalent value and prominence to each other.
                  Each page of the Co-Branded Site will also comply with Snap's
                  co-branding technical specifications, as updated in Snap's
                  sole discretion from time to time, including those set forth
                  at http://partnermarketing.snap.com/cobrand/cobranded_specs.
                  html or any other successor URL designated by Snap, and
                  include appropriate navigation features, such as an embedded
                  link on each Snap logo to the front door of the Snap Sites,
                  drop down menus, breadcrumb trails linking the User to the
                  page of the Snap Sites from which the User originated,
                  navigation bars and a Snap search box, that will include links
                  to the Snap Sites. Snap Marks and links to the Snap Sites will
                  have placement on the Co-Branded Site that is at least as
                  prominent as any promotions or links to other portal or search
                  engine companies that may be promoted on the Co-Branded Site.

         5.4.     LAUNCH DATE. The Company will use its best efforts to achieve
                  a Launch Date for the Co-Branded Site not sooner than the date
                  on which the Company has paid Snap pursuant to SECTION 9.1 and
                  paid Snap the initial fees pursuant to SECTIONS 9.2 AND 9.3
                  ("Initial Payment Date") and not later than seven days after
                  such Initial Payment Date; provided, however, that if the
                  Launch Date occurs later than seven days after the Initial
                  Payment Date or does not occur due to the fault of the
                  Company, then such failure will be deemed a material breach of
                  this Agreement by Company. Snap shall provide the Company with
                  reasonable assistance to launch the Co-Branded Site.
                  Notwithstanding the Launch Date, Snap shall have the right to
                  begin displaying Impressions immediately upon the Effective
                  Date. If the Launch Date of the Co-Branded Site does not occur
                  by seven days after the Initial Payment Date, due to the fault
                  of the Company, Snap shall be deemed to have delivered
                  Impressions and Click Thrus required to be delivered pursuant
                  to this Agreement on a daily, straight-line, pro-rata basis
                  for each day thereafter.

         5.5.     HOSTING. The Company will host the Co-Branded Site on its
                  servers (or on servers within its control) and will provide
                  all computer hardware, software and personnel necessary to
                  operate and maintain the Co-Branded Site as a functional site
                  accessible to Users.

         5.6.     ADVERTISEMENTS. The Company shall own and have the right to
                  use or sell all of the advertising inventory on the Co-Branded
                  Site. The Company will display advertising on the Co-Branded
                  Site consistent with the number, type, and placement of
                  advertising displayed on the Company Site; provided, however,
                  that all advertisements on the Co-Branded Site must also
                  comply with Snap's reasonable editorial guidelines in effect
                  from time to time. The Company will not display advertisements
                  of Competitors on the Co-Branded Site. Further, if any
                  advertisement on the Co-Branded Site is reasonably deemed
                  inappropriate by Snap, the Company shall upon notice from Snap
                  immediately remove the advertisement from the Co-Branded Site.
                  For example, pornography would reasonably be deemed
                  inappropriate by Snap, but advertisements for the Healthy
                  Sexuality magazine of the Company would not reasonably be
                  deemed inappropriate.

         5.7.     DNS MAPPING. Using Domain Name System mapping, the URL for the
                  Co-Branded Site will begin with http://healthgate.snap.com.
                  The Company agrees that Snap will be entitled to count all
                  page views of the Co-Branded Site towards Snap's traffic as
                  measured by Media Metrix and other Internet traffic-auditing
                  firms.

         5.8.     MOST FAVORED CUSTOMER PRICING. The Company shall offer on the
                  Co-Branded Site and the Company Site to Users from the Snap
                  Sites the Company's most favored customer pricing, which means
                  pricing and terms substantially similar to the lowest pricing
                  and most favorable terms offered by the Company to any other
                  Users of the Company Site. The Company shall maintain
                  competitive pricing for the products and services it offers.

6.       CO-BRANDED, ENHANCED, AND INTERNATIONAL EDITIONS.

         6.1.     CO-BRANDED EDITIONS. Company acknowledges that Snap produces
                  co-branded editions of the Snap Sites for various resellers,
                  distributors, other licensees and/or joint venture partners
                  (collectively the "Distributors"). In some cases, such
                  Distributors are entitled to replace Snap's default content
                  with other content within their own co-branded editions of any
                  Snap Site. Notwithstanding any other provisions of this
                  Agreement, if any such Distributor has exercised its right to
                  replace Company Content with other content, then Snap will not
                  be required to display the Promotions or Company Content
                  within such Distributor's co-branded edition of the Snap
                  Sites. If Snap does display the Promotions or Company Content
                  within a co-branded edition of any Snap Site, such display
                  will be governed by this Agreement.

         6.2.     ENHANCED AND INTERNATIONAL EDITIONS. Snap has created an
                  enhanced, high-speed version of the Snap Sites focused on rich
                  media content (together with any successor service(s) or
                  site(s) thereof and any co-branded editions of such service
                  that have been or may be developed for Snap's third party
                  distribution partners and licensees, the "Enhanced Sites") and
                  may desire to include appropriate rich media Company Content
                  within the Enhanced Sites. Snap is currently considering
                  creating one or more international editions of the Snap Sites
                  to reflect appropriate localized and local partner content
                  ("International Editions") and may desire to include localized
                  Company Content within the International Site. At Snap's sole
                  discretion, but subject to SECTION 3.2, all terms and
                  conditions contained in the Agreement related to the "Snap
                  Sites" may also apply to the Enhanced Site and International
                  Editions, and any Impressions and Click Thrus required under


                                       10
<PAGE>

                  the Agreement may be delivered on the Enhanced Sites,
                  International Editions, and/or the existing Snap Sites.
                  Subject to SECTION 3.2, the Company hereby acknowledges that,
                  Snap, in its sole discretion, may use appropriate content,
                  promotions and other material provided by Company within the
                  Enhanced Sites and the International Editions, and all
                  licenses set forth in this Agreement are hereby expanded to
                  include the Enhanced Sites and International Editions. In the
                  event that the Company does not have the legal right to
                  deliver to Snap any Company Content for use as contemplated by
                  this Agreement in certain geographical markets, then the
                  Company will use its best efforts to obtain the consent(s) of
                  the other parties to such contracts to deliver and use all
                  Company Content as contemplated by this Agreement in such
                  geographical markets. So long as the Company is using its best
                  efforts to obtain such consents, Snap will not, unless and
                  until such consent is obtained, use on any International
                  Edition such content for which delivery to or use on the
                  International Edition in a certain geographical location is
                  prohibited by the terms of a written contract to which the
                  Company is a party. The Company acknowledges that the Look and
                  Feel of the Enhanced Site will be designed for a
                  high-bandwidth audience and therefore may substantially differ
                  from the Look and Feel of the primary Snap Sites. The Company
                  further acknowledges that the Look and Feel of the
                  International Editions will be localized for the relevant
                  target audience (e.g., in terms of language, culture, and
                  ethnicity) and therefore may substantially differ from the
                  Look and Feel of the primary Snap Sites.

7.       NBC ON-AIR PROMOTION. During the Term, Snap will create and run a
         series (i.e., no less than two) of dedicated thirty-second Snap
         television advertisements which air during morning or daytime programs
         appearing on the NBC Television Network, local television stations or
         cable services for health, wellness and/or medicine related content
         areas on the Snap Sites (the "Spots"). Snap agrees that the Company
         will be featured in the Spots, in Snap's discretion, through either (i)
         a promotional tag (meaning a text or graphic promoting the Company's
         brands or services) of at least four seconds appearing at the end of
         such Spots, or (ii) an integrated sales message within the body of such
         Spots which at a minimum will consist of a voice over of at least four
         seconds in length regarding the Company's brand or service. Snap shall
         have sole discretion regarding the form and content of such
         advertisements but will consult with the Company regarding how the
         Company's brand or services will be featured in the Spots. Beginning no
         less than thirty days following the Effective Date and continuing
         throughout the rest of the Term, the Spots will run an average of four
         times per month. The Company acknowledges that all placement of brands
         or services within the Spots, as well as the Spots themselves, will be
         subject to the NBC Advertising Standard Terms and Conditions as well as
         the Advertising Standards set by NBC Broadcast Standards and Practices,
         and Snap will have no right or power to cause NBC to make any exception
         thereto for the Company or the Spots. The Company acknowledges that
         neither Snap nor NBC makes any guarantee regarding what the actual
         rating for any particular Spot will be and, therefore, will not be
         obligated to provide any make-goods hereunder.

8.       USER PROFILE DATA, COMMERCE OFFERINGS, AND DIRECT MARKETING.

         8.1.     DATA OWNERSHIP. The Company will be the sole owner of any
                  information that the Company collects from Users through the
                  Company Site, Snap will be the sole owner of any information
                  that Snap collects from Users through the Snap Sites, and the
                  Company and Snap shall jointly own any information that either
                  the Company or Snap collects from Users through the Co-Branded
                  Site. Further, if a User whose User Profile Data is contained
                  in the Company Database receives an email from Xoom pursuant
                  to SECTION 8.4 and purchases products offered in such email
                  through Xoom or an affiliated Web site,


                                       11
<PAGE>

                  then the User Profile Data for such User shall be owned
                  jointly by Xoom and the Company from and after the time of
                  such purchase.

         8.2.     USE OF INFORMATION AND CONFIDENTIALITY. The Company and Snap
                  shall exchange User Profile Data and other information
                  relating to Users of the Co-Branded Site at times and in a
                  manner as reasonably requested by either party and mutually
                  agreed between the parties, but in any event at least once per
                  month. Each party will have the right to use any information
                  provided by the other party pursuant to SECTION 11 subject to
                  the confidentiality restrictions set forth in SECTION 17.6.
                  Unless otherwise clearly disclosed to Users on the respective
                  site, all data collected from Users through the Co-Branded
                  Site will be kept confidential and not disclosed to third
                  parties in accordance with the published privacy policy of
                  Snap and Xoom.

         8.3.     SNAP MEMBER REGISTRATION. If any Company Content accessed
                  through links appearing on the Snap Sites or the Co-Branded
                  Site contains any Commerce Offering that requires the User to
                  register or submit any User Profile Data, then Snap has the
                  right in its sole discretion to cause any of the following:
                  (i) the Web page that requests the User Profile Data, (ii) any
                  other page relating to the Commerce Offering, or (iii) a
                  separate Snap Member registration page, to present the User
                  with an opportunity to register to become a Snap Member.

         8.4.     DIRECT MARKETING. During the Term, Xoom and, following the
                  NBCi Closing, NBCi, shall have the right to use, with the
                  prior approval of the Company which approval shall not be
                  unreasonably withheld, the information contained in the
                  Company Database for direct marketing purposes as set forth in
                  this Section. Xoom shall have a right to execute, or cause to
                  be executed, at least one promotional email offer per month
                  approved by the Company, which approval shall not be
                  unreasonably withheld, to all or some of the Users described
                  in the Company Database. Such email offers shall be drafted by
                  Xoom, approved by Company (and such approval shall not be
                  unreasonably withheld) and will appear to come from
                  "HealthGate and Xoom". Such email messages may have links to
                  the Snap Sites or the Co-Branded Site, as Xoom shall decide in
                  its sole discretion. Products offered in such emails may
                  include Xoom's products or services or third party products
                  and/or services that Xoom has the right to offer, and Xoom
                  shall select all of such products to be offered in its sole
                  discretion. Xoom shall also have the option to create and host
                  "sell" pages for any marketing campaign, arrange for purchase
                  orders to be processed and fulfilled, and for customer service
                  and inventory matters to be coordinated in relation to the
                  products offered in emails distributed pursuant to this
                  Section, as Xoom shall determine in its sole discretion. Xoom
                  shall send a copy of the email offer to the Company at least
                  forty-eight hours prior to the time at which the email
                  messages are to be sent. The Company may reject, but not
                  unreasonably, promotional email offers proposed by Xoom.

         8.5.     COMPANY OFFERS. Xoom shall, if the Company requests, make up
                  to one promotional email offer per month containing a Company
                  Product offer to Users described in the Company Database,
                  provided that such email messages will be sent by Xoom in
                  consultation with the Company. Xoom may reject promotional
                  email offers proposed by the Company that include products or
                  services which compete with products or services then offered
                  to Users of the Snap Sites (other than Company Products
                  offered through the Co-Branded Site or harvested Company
                  Content), or if such offer otherwise conflicts with a Snap
                  and/or Xoom contractual agreement or Snap's and/or Xoom's
                  privacy or merchandising philosophy.

                  payment (including the issuance of stock pursuant to SECTION
                  9.8) which is due on a day which is not a Business Day shall
                  be payable on the next succeeding day that is a Business Day.

         9.7.     INVOICE PROCEDURE. Snap shall send the Company all invoices
                  hereunder to the attention of Mary B. Miller, whose title is
                  Chief Financial Officer, and who has the authority to
                  authorize the payment of such invoices.

         9.8.     EQUITY. As provided in SECTION 9.2 and SECTION 9.3, $2,500,000
                  of the Year One AT Fee and $2,500,000 of the Year One Media
                  Fees shall all be payable to Snap in shares of the Company's
                  Common Stock (the "Shares"), valued at $10.00 per Share, on
                  November 3, 1999, or such later date as Snap and the Company
                  shall mutually agree (the "Equity Closing Date"). On or prior
                  to the Equity Closing Date, the Company and Snap shall
                  negotiate in good faith and execute a Stock Transfer Agreement
                  governing the transfer of the Shares, which agreement shall
                  contain standard representations, warranties, covenants and
                  other terms and conditions reasonably satisfactory to both
                  Snap and the Company. On the Equity Closing Date, the Company
                  agrees to execute and deliver to Snap a registration rights
                  agreement reasonably acceptable to Snap that provides Snap
                  with piggyback registration rights that are subject to the
                  limitations on priority of registration permitted under the
                  Company's existing registration agreements. At Snap's
                  direction, the Shares shall be issued to an escrow agent (the
                  "Escrow Agent") pursuant to an Escrow Agreement to be executed
                  by the Company, Snap and the Escrow Agent named therein (the
                  "Escrow Agreement") and, 45 days following the Effective Date,
                  released to Snap.

10.      TERM; TERMINATION.

         10.1.    TERM. The term of this Agreement will begin on the Effective
                  Date and end on the last day of the thirty-seventh month after
                  the Effective Date, unless otherwise terminated or extended as
                  set forth in this Agreement (the "Term").

         10.2.    TERMINATION FOR CAUSE. Either Snap or the Company may
                  terminate this Agreement at any time by giving written notice
                  of termination to the other parties if any other party commits
                  a material breach of its obligations hereunder that is not
                  cured within thirty days after notice thereof from a
                  non-breaching party; provided, however, that if the Company
                  fails to make a payment as required hereunder, Snap or Xoom,
                  as the case may be, may terminate this Agreement fifteen days
                  following the date of notice of such non-payment if any such
                  payment is not made within fifteen days after the Company's
                  receipt of such notice. Snap or Xoom may terminate this
                  Agreement immediately, and shall have no further obligation
                  under this Agreement, if the Company becomes insolvent; makes
                  an assignment for the benefit of creditors; makes or sends
                  notice of a bulk transfer; calls a meeting of its creditors
                  with respect to its inability to pay its obligations owed to
                  such


                                       14
<PAGE>

                  creditors on customary terms; defaults under any agreement,
                  document or instrument relating to the Company's indebtedness
                  for borrowed money; ceases to do business as a going concern;
                  a petition is filed by or against the Company under any
                  bankruptcy or insolvency laws; or the Company experiences a
                  change in its ownership, such that a person, corporation or
                  other legal entity with a direct competitive interest (i.e.,
                  owns or operates a search and aggregation portal site on the
                  Web) holds an equity interest in the Company, without Snap's
                  prior, written consent to such ownership.

         10.3.    TERMINATION REGARDING COMPANY CONTENT. Snap may terminate this
                  Agreement at any time by giving written notice of termination
                  to the Company if the Company fails to timely deliver,
                  pursuant to SECTION 3.2, any material part of the Company
                  Content, including updates, and such failure is not cured
                  within ten days after the Company's receipt of notice thereof
                  from Snap.

         10.4.    TERMINATION REGARDING INITIAL REGISTRATION DATE. In the event
                  that the Initial Registration Date has occurred on or before
                  February 28, 2000, Snap may, in its sole discretion, terminate
                  this Agreement. If Snap elects to terminate this Agreement
                  under this SECTION 10.4, then the Company shall be required to
                  enter into an agreement within five days of such termination
                  to purchase Impressions from Snap having a value of $450,000
                  calculated at a 30% discount from the rates set forth in the
                  applicable Snap's standard rate card attached hereto as
                  EXHIBIT B and otherwise on Snap's standard terms and
                  conditions. The parties acknowledge and agree that the amount
                  of liquidated damages described above is a reasonable estimate
                  of the actual damages that Snap would suffer and incur as a
                  result of the failure of the Initial Registration Date to
                  occur by such date.

         10.5.    TERMINATION REGARDING PAYMENT OF EQUITY. Snap shall have a
                  right to terminate this Agreement, in its sole discretion, in
                  the event that the Company defaults in the performance of its
                  obligations pursuant to SECTION 9.8 or its obligations
                  pursuant to any agreement entered into between the Company and
                  Snap pursuant to SECTION 9.8. If Snap elects to terminate this
                  Agreement under this SECTION 10.5, then the Company shall be
                  required to enter into an agreement within five days of such
                  termination to purchase Impressions from Snap having a value
                  of $450,000 calculated at a 30% discount from the rates set
                  forth in the applicable Snap's standard rate card attached
                  hereto as EXHIBIT B and otherwise on Snap's standard terms and
                  conditions.

         10.6.    TERMINATION REGARDING FAILURE OF THE NBCI CLOSING. In the
                  event that the NBCi Closing does not occur on or before March
                  31, 2000, the Company shall have the option to terminate this
                  Agreement by giving written notice of termination to each of
                  Snap and Xoom. Upon the Company's exercise of this right of
                  termination, Snap shall return to the Company, within five
                  days of such termination, all consideration received by Snap
                  from the Company under this Agreement, and the parties hereto
                  shall have no further obligations or liabilities hereunder
                  except for such obligations and liabilities which are
                  expressly intended to survive the termination of this
                  Agreement.

         10.7.    CONSEQUENCES OF TERMINATION. Termination by Snap shall not
                  affect the rights and obligations of Xoom under this
                  Agreement, and termination by Xoom shall not affect the rights
                  and obligations of Snap under this Agreement. Upon the
                  termination or expiration of this Agreement, all licenses
                  granted hereunder shall immediately terminate; each party
                  shall return or destroy, all Confidential Information of the
                  other party in its possession. In addition, in the event this
                  Agreement is terminated pursuant to SECTION 10.2 and/or 10.3,
                  then all monies paid by the Company to Snap hereunder prior to
                  the termination


                                       15
<PAGE>

                  shall be deemed non-refundable except as expressly stated
                  otherwise in this Agreement. Finally, in the event this
                  Agreement is terminated by Snap only pursuant to SECTION 10.2
                  and/or SECTION 10.3 (excluding termination for Company's
                  failure to maintain the Company Site, Company Content or the
                  Co-Branded Site as Best of Breed pursuant to SECTION 3.5),
                  then the Company shall continue to pay 55% of all fees payable
                  by the Company to Snap during the remainder of the Term as
                  liquidated damages. Such payments shall be due and payable on
                  the dates they would have been due and payable if the
                  termination had not occurred. The parties acknowledge and
                  agree that it would be impractical to estimate the amount of
                  any damages that could arise out of any material breach of
                  this Agreement or termination pursuant to SECTION 10.2 and/or
                  SECTION 10.3, and agree that the amount of liquidated damages
                  described above is a reasonable estimate of the actual damages
                  that Snap would suffer and incur as a result of such breach or
                  termination of this Agreement. No party shall be liable to the
                  others for damages of any sort resulting solely from
                  terminating this Agreement in accordance with its terms.

11.      REPORTS, RECORDS, AND ACCOUNTS.

         11.1.    SNAP AND XOOM REPORTS. Within 15 days after the end of each
                  month during the Term, Snap and Xoom will provide to the
                  Company their standard advertising reports for User traffic
                  generated from the Promotions for such month.

                  during the Term, the Company will provide to Snap a complete
                  and detailed report that includes, at a minimum, for such

                  to SECTION 9.5, (iv) the number of unique Users to the
                  Co-Branded Site from the Health Channel, (v) the number of

                  (vi) the number of Users and User Profile Data for Users who
                  click through from the Snap Sites to the Company Site and/or

                  Co-Branded Site originating from the Snap Sites using a cookie
                  or other similar technology to assist the Company in obtaining
                  the foregoing data.

         11.3.    RECORDS AND ACCOUNTS. The Company agrees to keep, on a
                  continuing basis, full and accurate records and accounts,
                  including, without limitation all logs and reports, sufficient
                  to permit Snap and Xoom to verify the accuracy of all reports
                  submitted by the Company as hereinabove required. Snap and
                  Xoom shall have the right, at their sole expense, to examine
                  such books and records, whether in electronic format or
                  otherwise, to the extent that such examination is necessary
                  and pertinent to the foregoing verification, during reasonable
                  business hours, using its employees or principals, or through
                  outside, authorized representatives. In the event such an
                  examination reveals that any of the reports submitted or
                  payments made by the Company to Snap, as hereinabove required,
                  understated the monies owed by five percent (5%) or more, then
                  the Company shall, in addition to the payment of the
                  additional monies owed fees determined by such examination,
                  promptly pay to Snap the reasonable cost of such examination.

         16.4.    INDEMNIFICATION PROCEDURES. If any party entitled to
                  indemnification under this Section (an "Indemnified Party")
                  makes an indemnification request to the other, the Indemnified
                  Party shall permit the other party (the "Indemnifying Party")
                  to control the defense, disposition or settlement of the
                  matter at its own expense; provided that the Indemnifying
                  Party shall not, without the consent of the Indemnified Party
                  enter into any settlement or agree to any disposition that
                  imposes an obligation on the Indemnified Party that is not
                  wholly discharged or dischargeable by the Indemnifying Party,
                  or imposes any conditions or obligations on the Indemnified
                  Party other than the payment of monies that are readily
                  measurable for purposes of determining the monetary
                  indemnification or reimbursement obligations of Indemnifying
                  Party. The Indemnified Party shall notify the Indemnifying
                  Party promptly of any claim for which Indemnifying Party is
                  responsible and shall cooperate with the Indemnifying Party in
                  every commercially reasonable way to facilitate defense of any
                  such claim; provided that the Indemnified Party's failure to
                  notify Indemnifying Party shall not diminish Indemnifying
                  Party's obligations under this Section except to the extent
                  that Indemnifying Party is materially prejudiced as a result
                  of such failure. An Indemnified Party shall at all times have
                  the option to participate in any matter or litigation through
                  counsel of its own selection and at its own expense.

17.      MISCELLANEOUS.

         17.1.    PROMOTION OF SNAP SITES. The Company may accept advertising
                  from other portals or search engines. If the Company accepts
                  advertising from other portals or search engines, and the
                  Company promotes such portals or search engines within a
                  "partner" area of the Company Site, then the Company shall
                  display the Snap Marks on such area of the Company Site at
                  least as prominently as such portal or search engine entity.
                  The Company shall ensure that the Snap Marks on the Company
                  Site link to the Co-Branded Site or the Health Channel.

         17.2.    ASSIGNMENT. Snap shall have the right to assign all of its
                  rights and liabilities hereunder to an affiliate or to any
                  person or entity that (i) acquires all or substantially all of
                  Snap's operating assets (whether by asset sale, stock sale,
                  merger or otherwise) or (ii) results from a merger or
                  reorganization of Snap pursuant to any plan of merger or
                  reorganization. Xoom shall have the right to assign all of its
                  rights and liabilities hereunder to an affiliate or to any
                  person or entity that (i) acquires all or substantially all of
                  Xoom's operating assets (whether by asset sale, stock sale,
                  merger or otherwise) or (ii) results from a merger or
                  reorganization of Xoom pursuant to any plan of merger or
                  reorganization. Without limiting the generality of the
                  foregoing, the Company expressly acknowledges that Snap and
                  Xoom will each have the right to freely assign this Agreement
                  or the operative rights and obligations hereof to any entity
                  resulting from the merger or other similar combination of Snap
                  and Xoom. The Company may assign all of its rights and
                  liabilities to another person, if such person or entity
                  accepts in writing all of the Company's rights, obligations
                  and liabilities hereunder, such person or entity is not a
                  Competitor, and the Company provides prior written notice to
                  Snap of such assignment.

         17.3.    RELATIONSHIP OF PARTIES. This Agreement will not be construed
                  to create a joint venture, partnership or the relationship of
                  principal and agent between the parties hereto, nor to impose
                  upon either party any obligations for any losses, debts or
                  other obligations incurred by the other party except as
                  expressly set forth herein. In no event will Snap or Xoom be
                  liable for the actions, omissions, duties or obligations of
                  the other under this Agreement.


                                       19

         17.4.    APPLICABLE LAW. This Agreement will be construed in accordance
                  with and governed by the laws of the State of California,
                  without regard to principles of conflicts of law. Litigation
                  of disputes under this Agreement shall be conducted in courts
                  located in the City of San Francisco, California. The parties
                  hereto consent to the jurisdiction of any local, state or
                  federal court in which an action is commenced and located in
                  accordance with the terms of this Section and that is located
                  in San Francisco, California. The parties further agree not to
                  disturb such choice of forum, and if not resident in such
                  state, waive the personal service of any and all process upon
                  them, and consent that such service of process may be made by
                  certified or registered mail, return receipt requested,
                  addressed to the parties as set forth herein.

         17.5.    CONFIDENTIALITY. In connection with the activities
                  contemplated by this Agreement, each party may have access to
                  confidential or proprietary technical or business information
                  of any other party, including without limitation (i)
                  proposals, ideas or research related to possible new products
                  or services; (ii) financial statements and other financial
                  information; (iii) any reporting information in SECTION 11;
                  and (iv) the material terms of this Agreement and the
                  relationship between the parties; provided, however, that such
                  information will be considered confidential only if it is
                  conspicuously designated as "Confidential," or if provided
                  orally, identified at the time of disclosure as confidential
                  (collectively, "Confidential Information"). Each party will
                  take reasonable precautions to protect the confidentiality of
                  the other party's Confidential Information, which precautions
                  will be at least equivalent to those taken by such party to
                  protect its own Confidential Information. Except as required
                  by law or as necessary to perform under this Agreement, no
                  party will knowingly disclose the Confidential Information of
                  any other party or use such Confidential Information for its
                  own benefit or for the benefit of any third party. Each
                  party's obligations in this Section with respect to any
                  portion of the other party's Confidential Information shall
                  terminate when the party seeking to avoid its obligation under
                  such Section can document that: (i) it was in the public
                  domain at or subsequent to the time it was communicated to the
                  receiving party ("Recipient") by the disclosing party
                  ("Discloser") through no fault of Recipient; (ii) it was
                  rightfully in Recipient's possession free of any obligation of
                  confidence at or subsequent to the time it was communicated to
                  Recipient by Discloser; (iii) it was developed by employees or
                  agents of Recipient independently of and without reference to
                  any information communicated to Recipient by Discloser; (iv)
                  it was communicated by the Discloser to an unaffiliated third
                  party free of any obligation of confidence; or (v) the
                  communication was in response to a valid order by a court or
                  other governmental body, was otherwise required by law or was
                  necessary to establish the rights of either party under this
                  Agreement.

         17.6.    PRESS RELEASE. No party will make any public statement or
                  other announcement (including without limitation, issuing a
                  press release or pre-briefing any member of the press or other
                  third party) relating to the terms or existence of this
                  Agreement without the prior written approval of the other
                  parties. Notwithstanding the foregoing and SECTION 17.5, the
                  parties may issue an initial joint press release, the timing
                  and wording of which will be subject to each party's
                  reasonable approval, regarding the relationship between the
                  parties.

         17.7.    INJUNCTIVE RELIEF. Each party agrees that in the event of a
                  breach or alleged breach of SECTIONS 17.5 or 17.6 that the
                  other parties shall not have an adequate remedy at law,
                  including monetary damages, and that the other parties shall
                  consequently be entitled to seek a temporary restraining
                  order, injunction, or other form of equitable relief against


                                       20
<PAGE>

                  the continuance of such breach, in addition to any and all
                  remedies to which any other party shall be entitled.

         17.8.    CAPTIONS AND SECTION HEADINGS. Captions and section headings
                  used in this Agreement are for convenience only and are not a
                  part of this Agreement and shall not be used in construing it.
                  Except as otherwise specifically provided, any reference in
                  this Agreement to a section or exhibit shall be deemed to be a
                  reference to such section or exhibit of this Agreement.

         17.9.    SURVIVAL. Termination or expiration of this Agreement for any
                  reason shall not release any party from any liabilities or
                  obligations set forth in this Agreement which (i) the parties
                  have expressly agreed shall survive any such termination or
                  expiration, or (ii) remain to be performed or by their nature
                  would be intended to be applicable following any such
                  termination or expiration.

         17.10.   TAXES. For all fees or charges payable hereunder by the
                  Company to Snap, the Company will pay or reimburse Snap for
                  50% of any taxes or fees (including all federal, state, or
                  local taxes) associated with Snap's provision of the services
                  hereunder to Company, except that Company will have no
                  liability for any taxes based on Snap's net assets or net
                  income, or for which Company has an appropriate resale or
                  other exemption.

         17.11.   FORCE MAJEURE. If any party shall be delayed in its
                  performance of any obligation hereunder or be prevented
                  entirely from performing any such obligation due to causes or
                  events beyond its reasonable control, including without
                  limitation any act of God, fire, strike or other labor
                  problem, such delay or non-performance shall be excused and
                  the time for performance shall be extended to include the
                  period of such delay or non-performance.

         17.12.   DISPUTE RESOLUTION. In the event that any dispute arises
                  hereunder, the parties agree that prior to commencing
                  litigation, arbitration, or any other legal proceeding, each
                  party shall send an officer of such party to negotiate a
                  resolution of the dispute in good faith at a time and place as
                  may be mutually agreed. Each officer shall have the power to
                  bind its respective party in all material respects related to
                  the dispute. If the parties cannot agree on a time or place,
                  upon written notice from either party to the other, the
                  negotiations shall be held at the principal executive offices
                  of Snap 21 days following such notice (or on the next
                  succeeding Business Day, if the 21st day is not a Business
                  Day).

         17.13.   NOTICES. All notices or other communications that shall or may
                  be given pursuant to this Agreement, shall be in writing, in
                  English, shall be sent by certified or registered air mail
                  with postage prepaid, return receipt requested, by facsimile,
                  overnight express mail, or by hand delivery. Such
                  communications shall be deemed given and received upon
                  confirmation of receipt, if sent by facsimile; the day after
                  delivery if by overnight express mail; or upon delivery if
                  hand delivered; or upon receipt of mailing, if sent by
                  certified or registered mail; and shall be addressed to the

                               Keyword Promotions

1.    Keywords. Subject to availability in Snap's inventory, the Company shall
      provide Snap with no more than 300 health-related keywords. For any
      keywords protected by trademark or servicemark rights, Snap shall have the
      right to accept or reject such term regardless of availability. In the
      event Snap accepts such a keyword protected by trademark or service mark
      rights, (i) the Company shall indemnify, hold harmless, and defend Snap as
      set forth in Section 16 of the Agreement to which this Exhibit is attached
      and (ii) Snap shall have the right, in its sole discretion, to terminate
      immediately its acceptance in the event Snap becomes aware of third party
      claims regarding such keyword (e.g., demand letter, complaint, etc.).

2.    50% Exclusivity. At least one half of all keyword search results for only
      such keywords will result in a Company Keyword Promotion. This Section 2
      of this Exhibit A will not apply to keyword searches containing the
      selected keywords and also containing additional words. For example, if
      "health" is a selected keyword, a search on "health care" means this
      Section 2 of this Exhibit A shall not apply to this search. If all of the
      Impressions required to be delivered pursuant to Section 3.3 of the
      Agreement have been delivered during any of Year One, Year Two, Year Three
      or Year Four, then this Section 2 of this Exhibit A shall no longer apply
      to keyword searches conducted during the remainder of such year.

                                    Exhibit C

                          General Performance Standards

The Company Site, the Co-Branded Site and the Company's related operations must
comply with the following performance standards throughout the Term:

1.    The Company Site and Co-Branded Site will be operational and fully
      functional in all material respects (i.e. capable of displaying
      information and conducting transactions as contemplated in the ordinary
      course of business) at least 99% of the time during any 30 day period.

2.    The average time required to start displaying the HTML on a page of the
      Company Site or Co-Branded Site after a link from the Snap Sites shall not
      exceed a daily average of five seconds, and the average time required to
      deliver an entire page of the Company Site or Co-Branded Site over the
      open Internet shall not exceed a daily average of six seconds. For
      measurements required in this Section, the Company may assume standard T1
      connectivity to the Internet.

3.    Without limiting the effect of Sections 1 and 2, the Company shall provide
      to Users coming to the Company Site or the Co-Branded Site from the
      Promotions at least the same level of service as is offered to Users
      coming directly to the Company Site.

4.    The Company Site and Co-Branded Site will offer personal health and
      medical products and services as well as links to various personal health
      and medical resources and shall not: (i) contain defamatory or libelous
      material or material which discloses private or personal matters
      concerning any person, without such person's consent; (ii) permit to
      appear or be uploaded any messages, data, images or programs which are
      illegal, contain nudity or sexually explicit content or are, by law,
      obscene, profane or pornographic; or (iii) permit to appear or be uploaded
      any messages, data, images or programs that would knowingly or
      intentionally (which includes imputed intent) violate the property rights
      of others, including unauthorized copyrighted text, images or programs,
      trade secrets or other confidential proprietary information, or trademarks
      or service marks used in an infringing fashion.

5.    If any of the performance standards set forth above are not met by the
      Company, Snap may immediately remove any or all links to the Company Site
      or Co-Branded Site, as applicable, at Snap's sole discretion. If the
      Company Site or the Co-Branded Site fails to operate fully and
      functionally in any material respect for any period of four or more
      consecutive hours, even if otherwise in compliance with the performance
      standards, Snap may immediately remove any or all links to the Company
      Site or Co-Branded Site, as applicable, at Snap's sole discretion until
      such time as the Company notifies Snap that such Company Site or
      Co-Branded Site has resumed acceptable operation. These remedies are for
      Snap's editorial purposes and in no way limit Snap's ability to terminate
      this contract or pursue any other remedies hereunder in the event the
      performance standards set forth herein are not met.

                                    Exhibit D

                            Technical Specifications:
                          Html Harvest/Partner Segment

Standard HTML Harvest:

Introduction

A partner segment is an html chunk that is "harvested" from your site and
published within an existing template on the Snap Website. The Snap Harvester
works by accessing a "Harvest URL" located on your servers and retrieving any
html and images that reside there. This information is then processed and
published to the Snap live site, replacing the previous content.

Timeline

o     Read these specifications and contact the designated Snap Technical
      Contact for questions.

o     Set up a single test page and send the url to the Snap Technical Contact
      for testing.

o     Once approved, begin updating your content regularly.

Harvest File/URL

Each partner segment (html chunk) that you would like us to harvest should have
a unique harvest url. This harvest url is essential to our harvester and must be
static. Snap's harvester will pick up this file on a schedule that's mutually
agreed upon, process it, and replace the former content on our live site. If you
are providing multiple partner segments, each segment should have a unique and
static url.

Sample Harvest File (View the source)

http://destinations.previewtravel.com/DestGuidesSnap/0,1778,SNP_14,00.html
(includes optional meta tags)

Sample File on the Snap Site

http://www.snap.com/main/page/pcp/0,3,-1624,00.html

Technical Requirements

Snap expects all page content to be complete and self-contained. Snap will not
change harvested content. Snap can refuse to publish content if the content does
not meet the specifications.

In order for the Harvest to function correctly, your content must meet the
following guidelines exactly:

o     Because the html for your content is inserted into a snap page template,
      your html must not contain any body attributes. No body bgcolor, vlink
      etc. This will cause harvesting to fail.
o     You may not put any information in the head section of your file besides
      meta tags. No Javascript.
o     The total content harvested must be 32K or less in cumulative data size.
      For page loading purposes, we suggest limiting your content (text and
      images) to 20K if possible. If this is not feasible please notify Snap.
o     Your content should be designed to be scalable for width. If fixed width,
      design for less than=640 pixels or width specified by a Snap Product
      Manager.
o     Links must be valid indefinitely, as your content will stay live on Snap
      until you update it.
o     All links to your site must use full (absolute) URLs.

Scheduling


                                       26
<PAGE>

We request updates as often as is appropriate for the topic. News, for instance,
should update more often than Living. Snap can harvest content as often as every
20 minutes. Tell us your preferred schedule and we'll work to accommodate it.

Partner Logo Note

We require you to include your brand name, either using a logo (suggested) or
text branding -- or both. Placement of the provider logo which links to the
partner site will be at the bottom of the PCP unless otherwise authorized by
Snap. Because PCPs at Snap function as resource centers for our users, excessive
advertising notices and branding is not allowed.

Images

o     Images can reside anywhere on the partner site, not necessarily in the
      harvest directory. They must be accessible via HTTP.
o     Assign height and width values, in pixels, to image tags. No scaled
      images.
o     No image file names reused for different images to avoid caching problems
      for users.

Fonts

We ask that you use the Snap fonts for the content you provide to Snap. Although
our only requirement is that you use the font face Arial, Helvetica (-1) for
body text, we also recommend the following for page consistency:

Captions, etc., are in Arial -2.
Headlines are in Arial regular bold.
Titles are in Verdana +1 Bold
Other type is Verdana -2

For your information, our default [BODY] settings are:

Text color is 333333
Link color is default blue 0000FF
Vlink color is 666666
NOTE: Some highlight links will be red: FF0000

Colors

We require that all partner content pages that you provide be designed for a
white background. We ask that you work within the Websafe 216 Palette.

Multimedia Files

If you are linking to pages which require plug-ins or controls, the link to such
page must notify the user of the requirement: for example, a graphic or text
note next to a link to a QuickTime video clip.

Advertisements

Unless specified by the contract or your Snap Contact, you may not include
advertisement banners within your content. Remember, your html is being inserted
into an existing page that already contains a page header and an advertisement.
This will cause harvesting to fail.

Additional limits

Your HTML content must not contain: Javascript, Java applets, ActiveX objects,
server-side includes, server-side executables, frames, CGI programs, files which
require plug-ins or controls, anything which creates a separate window
(including links, programs, etc.), BASE HREF tags, embedded files (that is,
files which use the [OBJECT] tag). Your page may also not include frames or
pop-up windows.


                                       27

Suggestions

Please close your tags!
Limit use of nested tables to avoid slowing the page load.
Form submissions may not link to Snap's servers without prior notification.

conducted and to enter into and carry out the transactions contemplated by this
Agreement. The Company is duly qualified to transact business as a foreign
corporation and is in good standing in each of the other jurisdictions in which
the ownership or leasing of its properties or the conduct of its business

hereby have been duly authorized, executed and delivered by the Company and are
the legal, valid and, assuming due execution and delivery by the other parties
thereto, binding obligations of the Company, enforceable in accordance with
their terms. The execution, delivery and performance of this Agreement and each

         2.3. VALIDITY OF SHARES. The Shares, when issued and the consideration

non-assessable. The Company has the full corporate power, right and authority,
to issue and sell to the Investor at the Closing, the Shares, as contemplated
herein, and upon consummation of the transactions contemplated by this Agreement
the Investor will have acquired good and marketable title to the Shares free and
clear of any claims, liens, restrictions on transfer or voting or encumbrances
other than those arising under the federal and state securities laws of the
United States of America.

         2.4. CAPITALIZATION. (a) The authorized capital stock of the Company

<PAGE>

converted into 3,458,261 shares of Common Stock effective with the Company's

         2.5. FINANCIAL STATEMENTS. Schedule 2.5 sets forth: (i) an unaudited

statements of income and cash flows for the six months then ended, and (ii) an
audited balance sheet of the Company as of December 31, 1998 and the related
audited statements of income and cash flows for the twelve months then ended, in
each case audited by PriceWaterhouseCoopers, LLP independent certified public
accountants, (the balance sheet of the Company as at December 31, 1998 is
hereinafter referred to as the "Balance Sheet" and the balance sheet of the
Company as at June 30, 1999 is hereinafter referred to as the "Closing Balance
Sheet"). Such financial statements, except as indicated therein, have been
prepared in accordance with United States generally accepted accounting
principles ("GAAP") consistently applied throughout the period indicated. The
Balance Sheet and the Closing Balance Sheet fairly present the financial
condition of the Company at the dates thereof and, except as indicated therein,
reflect all claims against and all debts and liabilities of the Company, fixed
or contingent, as at the dates thereof, required to be shown thereon under GAAP,
and the related statements of income and retained earnings fairly present the
results of operations of the Company for the period indicated.

         2.6. CHANGES IN CONDITION. Since June 30, 1999 (the "Balance Sheet
Date"), there have occurred no event or events that, individually or in the
aggregate, have caused a Material Adverse Effect. Without limiting the
foregoing, the Company has not (a) declared any dividend or other distribution
on any shares of its capital stock, (b) made any payment (other than
compensation to its directors, officers and employees at rates in effect prior
to the Balance Sheet Date or for bonuses accrued in accordance with normal
practice prior to the Balance Sheet Date) to any of its affiliates, (c)
increased the compensation, including bonuses, payable or to be payable to any
of its directors, officers, employees or affiliates, or (d) entered into any
material contractual obligation, or entered into or performed any other
transaction, not in the ordinary and usual course of business and consistent
with past practice, other than as disclosed in the Disclosure Statement dated
November 3, 1999 delivered to the Investor (the "Disclosure Statement") or
disclosed directly to the Investor.

         2.7. CONFORMITY WITH LEGAL REQUIREMENTS. The operations of the Company
as now conducted are not in violation of, nor is the Company in default under,
any legal requirements presently in effect, except for such violations and
defaults as do not and will not, in the aggregate, have a Material Adverse
Effect. The Company (i) has all franchises, licenses, permits or other authority
reasonably necessary for the conduct of its business as now conducted, and (ii)
is not in violation of any such authorizations except, in each case, to the
extent that the failure to have such authorizations or such violations is
reasonably likely to cause a Material Adverse Effect.

its By-Laws or any material note, indenture, mortgage, lease, agreement,
contract, purchase order or other instrument, document or agreement to which it

with respect to any order, writ, injunction or decree of any court or any
federal, state, municipal or other governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign. There exists no
condition, event or act which after notice, lapse of time, or both, is
reasonably likely to constitute a default by the Company which would have a
Material Adverse Effect. To the Company's knowledge, no third party is in
default under any agreement, contract or other instrument, document, or
agreement to which the Company or any subsidiary is a party or by which any of
them or any of their property is affected.

         2.9. EFFECT OF TRANSACTIONS. The execution, delivery and performance of
this Agreement, and any other agreements, instruments, or documents contemplated
hereby, the issuance, sale and delivery of the Shares and compliance with the
provisions hereof and thereof by the Company, do not and will not, with or
without the passage of time or the giving of notice or both (a) violate any
provision of law, statute, rule or regulation or any ruling, writ, injunction,
order, judgment or decree of any court, administrative agency or other
governmental body, or (b) conflict with or result in any breach of any of the
terms, conditions or provisions of, or constitute a default (or give rise to any
right of termination, cancellation or acceleration) under, or result in the
creation of any lien, security interest, charge or encumbrance upon any of the
properties or assets of the Company under its charter or bylaws or under any
note, indenture, mortgage, lease, license agreement, contract, purchase order or
other instrument, document or agreement to which the Company is a party or by
which it or any of its property is bound or affected which would have a Material
Adverse Effect.

         2.10. LITIGATION. There is no action, suit, proceeding or investigation
at law or equity or before or by any governmental commission, board or other
administrative agency pending or, to the knowledge of the Company, threatened
against or affecting the Company which questions the validity of this Agreement,
any other agreements, instruments or documents entered into by the Company
pursuant to this Agreement, the right of the Company to enter into them or to
consummate the transactions contemplated hereby or thereby, or which might
result, either individually or in the aggregate, have a Material Adverse Effect,
or any change in the current equity ownership of the Company. There is no
action, suit or proceeding pending against, or to the knowledge of the Company,
threatened against or affecting, the Company or any of its properties before any
court or arbitrator or any governmental body, agency or official which in any

the transactions contemplated hereby. There is no material litigation other than

each such case those contained in the Company's Certificate of Incorporation.

agreements, obligations, and conditions contained in this Agreement that are

any other agreement contemplated hereby, any exhibit hereto or thereto, nor any
report, certificate or instrument furnished to the Investor in connection with
the transactions contemplated in this Agreement contains any untrue statement of
a material fact or omits to state a material fact necessary in order to make the
statements contained herein or therein not misleading. The Company knows of no
information or fact that has or would have a Material Adverse Effect that has

Statement or any other agreement contemplated hereby, any exhibit hereto or
thereto, or any report, certificate or instrument furnished to the Investor.

3. REPRESENTATIONS AND WARRANTIES AND OTHER AGREEMENTS OF THE INVESTOR.

         3.1. REPRESENTATIONS AND WARRANTIES. The Investor hereby represents and
warrants to the Company that:

                    (a) AUTHORIZATION. The Investor has full power and authority
         to execute, deliver and perform this Agreement and to acquire the
         Shares, as contemplated herein; this Agreement constitutes the valid
         and legally binding obligation of the Investor, enforceable against the
         Investor in accordance with its terms.

                    (b) PURCHASE ENTIRELY FOR OWN ACCOUNT. The Shares to be
         received by the Investor as contemplated by this Agreement will be
         acquired for investment for the Investor for its own account, not as a
         nominee or agent and not with a view to the


                                      - 5 -


<PAGE>

         distribution of any part thereof. The Investor has no present
         intention of selling, granting any participation in, or otherwise
         distributing the same. The Investor does not have any contract,
         undertaking, agreement or arrangement with any Person to sell,
         transfer, or grant participation to such Person or to any third
         Person, with respect to the Shares.

                    (c) RESTRICTED SECURITIES. The Investor understands that the
         Shares may not be sold, transferred, or otherwise disposed of without
         registration under the U.S. Securities Act of 1933, as amended (the
         "1933 Act"), or an exemption therefrom, and that, in the absence of an
         effective registration statement covering the Shares or an available
         exemption from registration under the 1933 Act, the Shares must be held
         indefinitely. In the absence of an effective registration statement
         covering the Shares, the Investor will sell, transfer, or otherwise
         dispose of the Shares only in a manner consistent with its
         representations and agreements set forth herein.

                    (d) SUITABILITY. The Investor is an "accredited investor" as
         such term is defined in Rule 501(a) promulgated pursuant to the 1933
         Act.

                    (e) FINANCIAL CONDITION. The Investor's financial condition
         is such that it is able to bear the risk of holding the Shares for an
         indefinite period of time and can bear the loss of its entire
         investment in the Shares.

                    (f) EXPERIENCE. The Investor has such knowledge and
         experience in financial and business matters and in making high risk
         investments of this type that it is capable of evaluating the merits
         and risks of the purchase of the Shares.

                    (g) RISK AND DUE DILIGENCE. The Investor understands that
         the operation of the Company's business is subject to numerous risks
         and that the Shares are a speculative investment that involves a high
         degree of risk of loss of the entire investment therein. The Investor
         is cognizant of and understands such risks, including those set forth
         in the Disclosure Statement. The Investor has been allowed, upon
         request, to examine any document or agreement listed herein, and has
         had the opportunity to obtain any information concerning the Company,
         including the opportunity to ask questions of and receive answers from
         authorized representatives of the Company concerning this investment.

         3.2.       LEGENDS.  It is understood that the certificates evidencing
the Shares will bear substantially the following legend:

                    "The shares represented by this certificate have been
         acquired for investment, have not been registered under the Securities
         Act of 1933, as amended (the "Act") or any applicable state security
         laws and may not be offered, sold or otherwise transferred in the
         absence of a registration statement in effect with respect to the
         securities under


                                      - 6 -

SG Cowen Securities Corporation
Financial Square, 27th Floor

   As representative of the
   several Underwriters


Re: HealthGate Data Corp.

   o  Shares of Common Stock

Dear Sirs:

            In order to induce SG Cowen Securities Corporation ("SG Cowen"),
Volpe Brown Whelan & Company, LLC and NationsBanc Montgomery Securities LLC
(collectively, the "Underwriters") to enter into a certain underwriting
agreement with HealthGate Data Corp., a Delaware corporation (the "Company")
with respect to the public offering of shares of the Company's Common Stock, par
value $0.01 per share ("Common Stock"), the undersigned hereby agrees that for a
period of 180 days following the date of the final prospectus filed by the
Company with the Securities and Exchange Commission in connection with such
public offering, the undersigned will not, without the prior written consent of
SG Cowen, on behalf of the several Underwriters, (1) directly or indirectly,
offer, sell, assign, transfer, encumber, pledge, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant to purchase, lend, or otherwise dispose of, other
than by operation of law, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock (including,
without limitation, Common Stock which may be deemed to be beneficially owned by
the undersigned in accordance with the rules and regulations promulgated under
the Securities Act of 1933, as the same may be amended or supplemented from time
to time (such shares, the "Beneficially Owned Shares")) or (2) enter into any
swap or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of Common Stock whether any such
transaction described in clause (1) or (2) above is to be settled by delivery of
Common Stock or such other securities, in cash or otherwise.

            Notwithstanding the foregoing, the undersigned may transfer any
shares of Common Stock without the prior written consent of SG Cowen, to any
entity that controls, is controlled by or is under common control with the
undersigned; provided, however, that prior to such transfer

<PAGE>

each such transferee shall execute an agreement satisfactory to SG Cowen,
agreeing to hold such shares subject to the provisions hereof.

            Anything contained herein to the contrary notwithstanding, any
person to whom shares of Common Stock or Beneficially Owned Shares are
transferred from the undersigned shall be bound by the terms of this Agreement.

            In addition, the undersigned hereby waives, from the date hereof
until the expiration of the 180 day period following the date of the Company's
final Prospectus, any and all rights, if any, to request or demand registration
pursuant to the Securities Act of any shares of Common Stock that are registered
in the name of the undersigned or that are Beneficially Owned Shares.

undersigned hereby consents to the placing of legends and/or stop-transfer
orders with the transfer agent of the Common Stock with respect to any shares of
Common Stock or Beneficially Owned Shares.

            Whether or not the public offering actually occurs depends on a
number of factors, including market conditions. Any public offering will only be
made pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.
