                                 THE COMPANY 

   HealthDesk Corporation (the "Company"), a development stage company, is 
engaged in designing, developing and marketing HealthDesk(R) OnLine, a 
healthcare management and information system which enables consumers to take 
a more active role in their personal and family health. HealthDesk OnLine 
features easy-to-use Windows-based software designed to develop personal 
medical records and health management programs and access educational, health 
related information from the Company's private Website and over the Internet. 
The Company's proposed system is intended to lower the cost and improve the 
quality and accessibility of healthcare by promoting preventive maintenance 
and patient compliance and permitting electronic mail communications between 
consumers and healthcare providers and payers. HealthDesk OnLine is being 
developed in response to perceived market opportunities arising from 
increasing efforts of industry participants to stem the escalating cost of 
healthcare. 

   In July 1996, the Company commenced preliminary market testing of 
HealthDesk OnLine pursuant to a license agreement with Blue Cross/Blue Shield 
of Massachusetts ("BCMA"). The Company has modified HealthDesk OnLine to 
satisfy BCMA's requirements and BCMA is currently testing such product. In 
the event of successful initial acceptance testing, the proposed market test 
contemplates that BCMA will distribute HealthDesk OnLine to up to 50 of its 
employees and thereafter BCMA will have an opportunity to determine whether 
to distribute HealthDesk OnLine to up to 500 of its members. The market test 
is intended to provide information on the product's usability and acceptance 
by consumers and to test the technical aspects and functionality of the 
Company's software system. The Company also recently entered into an 
agreement with Blue Cross/Blue Shield of Iowa ("BCI") to conduct similar 
market testing activities. There can be no assurance that such market testing 
will be conducted on a timely basis or that such testing will be successful. 

   The Company's primary marketing strategy is to license HealthDesk OnLine 
to sponsoring organizations (including pharmaceutical companies, managed care 
organizations, disease management companies, employers and affinity groups) 
with access to significant numbers of potential subscribers. The Company 
intends to focus its efforts on healthcare organizations primarily 
responsible for bearing the financial risk of patients with chronic diseases. 
The Company recently entered into a letter of intent with Medical Inter- 
Insurance Exchange ("MIIX"), a medical malpractice insurance carrier, which 
contemplates that the Company will design, develop and test a software module 
for diabetic patients. The Company is currently evaluating various other 
commercialization strategies, including the license of HealthDesk OnLine to 
manufacturers of medical devices, pursuant to arrangements by which such 
manufacturers would bundle such product with the products of such 
manufacturers. The Company is also seeking to establish strategic 
relationships with third parties relating to product development and 
marketing. 

   The Company currently offers HealthDesk OnLine with no license fee to 
potential sponsoring organizations willing to participate in market testing 
activities. In the event of successful completion of market testing 
activities, the Company anticipates that its principal sources of revenues 
will be derived from license fees from sponsoring organizations and 
subscription and online content and usage fees from con-

                                        3

sumers. The Company will seek to expand its sources of revenues to include 
development fees for specific disease management software modules or 
features. In addition, the Company may seek revenues by including advertising 
in the system. The Company believes that the broad range of capabilities 
combined in HealthDesk OnLine, including the system's desktop and online 
functionality, and the system's ability to link consumers with healthcare 
payers and providers, differentiate HealthDesk OnLine from competitive 
products and make it attractive to potential sponsoring organizations seeking 
to contain healthcare costs. 

   The Company intends to use a portion of the proceeds of this offering to 
refine and enhance the capabilities of HealthDesk OnLine and expand system 
capacity. In addition to the proposed development and commercialization of 
specific disease management modules designed to monitor chronic conditions, 
the Company will seek to license or develop the following: personalized 
electronic newsletters designed to automatically search content databases and 
websites by topic on a periodic basis; an online "chat" capability; and 
software enhancements designed to assist users in both health risk assessment 
and symptom triage. The Company may also seek to develop features which will 
facilitate the input of data from medical devices, such as blood pressure 
cuffs, blood glucose monitors and peak flow meters, directly into HealthDesk 
OnLine which data may be monitored by healthcare providers. 

   Since its inception, the Company has engaged primarily in research and 
development and has generated limited revenues. The Company expects to incur 
significant up-front expenses in connection with product development and 
commercialization (including the payment of salaries for management, 
technical, marketing and other personnel), which will result in significant 
losses for the foreseeable future. There can be no assurance that the 
Company's product development efforts will be successfully completed or that 
HealthDesk OnLine will prove to be commercially viable. See "Risk Factors." 

   The Company was incorporated under the laws of the State of California in 
August 1992. The Company's executive offices are located at 2560 Ninth 
Street, Suite 220, Berkeley, California 94710, and its telephone number is 
(510) 883-2160. The Company's home page is located on the World Wide Web at 
http://www.healthdesk.com. 

                                  BACKGROUND 

   The Company introduced its initial product, HealthDesk, in early 1993. 
HealthDesk, which is marketed directly to consumers pursuant to agreements 
with independent sales representatives, contains certain of the medical 
records and healthcare management and information features of HealthDesk 
OnLine without online capabilities. The Company currently markets HealthDesk 
on a limited basis and does not expect future revenues derived from such 
product to be meaningful. See "Business -- Potential Markets and Marketing." 

   In October 1993, the Company entered into an agreement with Kaiser 
Foundation Health Plan of the Mid-Atlantic States of Washington, D.C. 
("Kaiser") pursuant to which the Company engaged in product development 
activities and Kaiser conducted limited consumer acceptance testing of the 
Company's initial product in consideration of $145,000. In February 1994, the 
Company entered into an agreement with Quantum Health Resources ("Quantum"), 
a company engaged in disease management services, pursuant to which the 
Company developed a software module for hemophilia patients and commenced 
development of a software module for cystic fibrosis patients in 
consideration of approximately $390,000. In 1994, Quantum conducted limited 
consumer acceptance testing of such hemophilia module. While the Company 
believes that the results of such testing were positive, the Company does not 
have any further arrangements with either Kaiser or Quantum to test such 
products. See "Business -- Market Testing." 

                              RECENT FINANCINGS 

   In February 1996, the Company completed a private placement of 1,059,600 
shares of Series A Convertible Preferred Stock (the "Series A Preferred 
Stock") at a price of $2.08 per share and received net proceeds of 
approximately $2,183,000. Each share of Series A Preferred Stock 
automatically converts into one share of Common Stock upon the consummation 
of this offering. See "Description of Securities." 

                                      4

   In July and August 1996, the Company issued an aggregate of $500,000 
principal amount of promissory notes to John Pappajohn, a director and 
principal shareholder of the Company, and Edgewater Private Equity Fund II, 
L.P. ("Edgewater"), a principal shareholder of the Company. James Gordon, a 
director of the Company, is president of the General Partner of Edgewater. 
Such notes will automatically convert into 100,000 shares of Common Stock at 
the initial public offering price per share on the earlier of the date of 
this Prospectus or March 31, 1997. See "Certain Transactions." 

   In October 1996, the Company consummated a financing (the "Bridge 
Financing") pursuant to which it issued an aggregate of (i) $2,000,000 
principal amount of promissory notes (the "Bridge Notes") which bear interest 
at the rate of 9% per annum and are due on the earlier of the consummation of 
this offering or October 11, 1997 and (ii) 400,000 shares of Common Stock. 
The Company will record the Bridge Notes at a discount of $900,000, which 
will be allocated to the 400,000 shares of Common Stock issued in connection 
with the Bridge Financing at an attributed price of $2.25 per share. 
Additionally, $154,000 of debt issuance costs will be recorded in connection 
with the Bridge Financing. The effective interest rate of the Bridge Notes is 
279%. The Underwriter acted as placement agent in connection with the Bridge 
Financing. The Company intends to use a portion of the proceeds of this 
offering to repay the entire principal amount of and accrued interest on the 
Bridge Notes. See "Use of Proceeds" and "Selling Shareholders and Plan of 
Distribution."

                                 RISK FACTORS 

   
   The securities offered hereby are speculative and involve a high degree of 
risk. Each prospective investor should carefully consider the following risk 
factors before making an investment decision. 
    

   1. Development Stage Company. The Company was organized in August 1992 and 
is still in the development stage. Since its inception, the Company has been 
engaged primarily in product development activities. The Company's initial 
product was introduced in early 1993 and has not yet proven to be 
commercially viable. As a result, the Company has no relevant operating 
history upon which an evaluation of its performance and prospects can be 
made. The Company will be subject to all of the risks, uncertainties, 
expenses, delays, problems and difficulties typically encountered in the 
establishment of a new business and the development and commercialization of 
new products. The Company has limited experience in developing and 
commercializing new products based on innovative technologies and there is 
limited information available concerning the potential performance of the 
Company's software or market acceptance of the Company's proposed products. 
There can be no assurance that unanticipated expenses, problems or technical 
difficulties will not occur which would result in material delays in product 
commercialization or that the Company's efforts will result in successful 
product commercialization. See "Business." 

   2. Limited Revenues; Significant and Continuing Losses; Qualified Report 
of Independent Auditors. The Company has not yet generated any meaningful 
revenues, and will not generate any meaningful revenues until after the 
Company successfully completes development and market testing of HealthDesk 
OnLine and attracts and retains a significant number of subscribers. For the 
period August 28, 1992 (inception) to September 30, 1996, the Company 
incurred a cumulative net loss of approximately $4,555,000. Since September 
30, 1996, the Company has continued to incur increasing and significant 
losses, and the Company anticipates that it will continue to incur 
significant losses until, at the earliest, it generates sufficient revenues 
to offset the substantial up-front expenditures and operating costs 
associated with developing and commercializing its proposed products. The 
Company will also incur non-recurring charges relating to the Bridge 
Financing of approximately $1,054,000 upon the consummation of this offering. 
There can be no assurance that the Company will be able to attract and retain 
a sufficient number of subscribers to generate meaningful revenues or achieve 
profitable operations or that HealthDesk OnLine will prove to be commercially 
viable. The Company's independent auditors have included an explanatory 
paragraph in their report stating that recurring losses during the 
development stage raise substantial doubt about the Company's ability to 
continue as a going concern. See Financial Statements. 

   3. Dependence on Offering Proceeds; Working Capital Deficit; Negative Cash 
Flow; Possible Need for Additional Financing. The Company's capital 
requirements relating to the development and commercialization of HealthDesk 
OnLine have been and will continue to be significant. The Company is 
dependent on the proceeds of this offering or other financing in order to 
continue in business and develop and commercialize its proposed products. The 
Company's capital requirements have exceeded its cash resources and, at 
September 30, 1996, the Company had a working capital deficit of $1,636,876 
and had a negative cash flow of $1,547,256 during the nine months ended 
September 30, 1996. Based on currently proposed plans and assumptions 
relating to its operations (including the timetable of, and costs associated 
with, product development and commercialization), the Company believes that 
the proceeds of this offering will be sufficient to satisfy its contemplated 
cash requirements for at least twelve months following the consummation of 
this offering. In the event that the Company's plans change, its assumptions 
change or prove to be inaccurate or if the proceeds of this offering prove to 
be insufficient to fund operations (due to unanticipated expenses, technical 
difficulties, problems or otherwise), the Company would be required to seek 
additional financing sooner than currently anticipated. There can be no 
assurance that the proceeds of this offering will be sufficient to permit the 
Company to successfully develop and commercialize HealthDesk OnLine or that 
any assumptions relating to the Company's operations will prove to be 
accurate. To the extent that the proceeds of this offering are not sufficient 
to enable the Company to generate meaningful revenues or achieve profitable 
operations, the inability to obtain additional financing will have a material 
adverse effect on the Company, including possibly requiring the Company to 
significantly curtail or cease its operations. In addition, any 
implementation of the Company's business plans subsequent to the twelve month 
period following this offering may require proceeds greater than the proceeds 
of this offering or otherwise currently available to the Company. There can 
be no assurance that any additional financing will be available to the 
Company on commercially reasonable terms, or at all. Any additional financing 
involving the issuance of equity securities could result in substantial 
dilution to the interests of the Company's shareholders. See "Use of 
Proceeds." 

                                      7 
<PAGE>

   4. Uncertainty of Product Development. Although the Company believes that 
the development efforts relating to the technological aspects of the basic 
HealthDesk OnLine platform are substantially completed, the Company has not 
yet completed third-party testing of the basic platform or the development or 
testing of any system enhancements or specific disease management modules. 
The Company will be required to commit considerable time, effort and 
resources to finalize such development and adapt its software to satisfy 
specific requirements of potential customers. Continued system refinement, 
enhancement and development efforts are subject to all of the risks inherent 
in the development of new products and technologies, including unanticipated 
delays, expenses, technical problems or difficulties, as well as the possible 
insufficiency of funds to satisfactorily complete development, which could 
result in abandonment or substantial change in product commercialization. 
There can be no assurance that product development efforts will be 
successfully completed on a timely basis, or at all, that the Company will be 
able to successfully adapt its software to satisfy specific requirements of 
potential customers, or that unanticipated events will not occur which would 
result in increased costs or material delays in product development or 
commercialization. In addition, while the Company believes that its software 
performs the principal functions for which it has been designed, the Company 
has only conducted limited tests of its software in connection with 
preliminary market testing activities. Consequently, there can be no 
assurance that such software will perform all of the functions for which it 
has been designed or prove to be sufficiently reliable in widespread 
commercial use. Technologies as complex as those incorporated into the 
Company's software may contain errors which become apparent subsequent to 
commercial use. Remedying such errors could delay the Company's plans and 
cause it to incur substantial additional costs. See "Business -- Product 
Development." 

   5. New Concept; Uncertainty of Market Acceptance and Commercialization 
Strategy. HealthDesk OnLine represents a new business concept. As is typical 
in the case of a new business concept, demand and market acceptance for 
HealthDesk OnLine as a newly introduced product is subject to a high level of 
uncertainty. Achieving market acceptance for HealthDesk OnLine will require 
significant efforts and expenditures by the Company to create awareness and 
demand by healthcare payers, providers and consumers. The Company's prospects 
will be significantly affected by its ability to successfully develop and 
maintain relationships with sponsoring organizations, which will promote 
their services using HealthDesk OnLine and, at the same time, attract 
significant numbers of subscribers. Because demand by payers, providers and 
consumers are substantially interrelated, any lack or lessening of demand by 
any of these would have an adverse effect on market acceptance for HealthDesk 
OnLine. The Company has not yet commenced significant marketing activities 
and has limited experience and limited financial, technical, personnel and 
other resources to independently undertake extensive marketing activities. 
Although the Company is currently evaluating a number of possible product 
marketing and distribution strategies, the Company initially intends to offer 
HealthDesk OnLine with no license fee to potential sponsoring organizations 
willing to participate in market testing in order to closely monitor 
performance and provide support for the users of such product. Such 
activities are expected to allow the Company to adjust and revise its 
proposed products in light of market needs and user feedback, to develop 
pricing strategies relative to cost structure, to test new products and to 
correct software or product defects which may arise. Thereafter, although the 
Company will seek to develop and commercialize specific disease management 
modules, the Company's primary marketing strategy is to license and sell 
HealthDesk OnLine to sponsoring organizations with access to significant 
numbers of potential subscribers. The Company's marketing strategy and 
preliminary and future marketing plans may be unsuccessful and are subject to 
change as a result of a number of factors, including progress or delays in 
the Company's marketing efforts, changes in market conditions (including the 
emergence of potentially significant related market segments for applications 
of the Company's technology), the nature of possible license and distribution 
arrangements which may become available to it in the future and economic, 
political, regulatory and competitive factors. To the extent that the Company 
is able to enter into satisfactory third-party marketing and distribution 
arrangements in the future, it will be largely dependent on the efforts of 
such third parties and on the marketability and sales of their products. 
There can be no assurance that the Company's strategy will result in 
successful product commercialization or that the Company's efforts will 
result in initial or continued market acceptance for the Company's proposed 
products. See "Business -- Potential Markets and Marketing." 

   6. Uncertainty of Market Testing Results. The Company currently proposes 
to conduct market testing of HealthDesk OnLine with BCMA and BCI and other 
potential sponsoring organizations. The Company's success may be highly 
dependent upon the results of these tests and there can be no assurance that 
such tests will be 

                                      8 
<PAGE>

successful. If such tests are not successful, the Company will be required to 
attempt to enhance or modify HealthDesk OnLine so that it will meet with 
sponsoring organization and consumer acceptance. There can be no assurance 
that the Company will be able to modify HealthDesk OnLine so that positive 
test results can be demonstrated. Even if test results are positive, there 
can be no assurance that sponsoring organizations will be sufficiently 
encouraged by the results to commit to use HealthDesk OnLine on a non-market 
test basis. They may elect to utilize other products, services or 
technologies which they believe to be more efficient or have other cost 
advantages over the Company's system. In addition, there can be no assurance 
that positive test results will translate into consumer acceptance over a 
longer period of time or that sponsoring organizations or consumers will be 
satisfied with operational results or that the results of market testing will 
be indicative of the ultimate success of product commercialization, 
particularly if installed in geographic areas with demographic 
characteristics different from those of test markets. See "Business -- Market 
Testing." 

   7. Competition; Technological Obsolescence. The markets that the Company 
intends to enter are characterized by intense competition and an increasing 
number of new market entrants who have developed or are developing 
potentially competitive products. The Company will face competition from 
numerous sources, including prospective customers which may develop and 
market their own competitive products and services, health information system 
vendors, software companies, online and Internet service providers and others 
with the technical capabilities and expertise which would encourage them to 
develop and commercialize competitive products or services. Several 
companies, including Healtheon Corp. ("Healtheon"), IBM Global Health 
Village, Med Access Corporation, CareSoft, Inc., Access Health, Inc. and 
America's Housecalls Network, have announced plans to develop and 
commercialize competitive product and service offerings. Certain of such 
competitors have substantially greater financial, technical, marketing, 
distribution, personnel and other resources than the Company, permitting such 
companies to implement extensive marketing campaigns, both generally and in 
response to efforts by additional competitors to enter into new markets and 
market new products and services. Healtheon has announced that it has entered 
into an agreement with BCMA relating primarily to the electronic exchange of 
health plan benefit information between consumers and health plans. There can 
be no assurance that Healtheon's relationship with BCMA will not adversely 
affect the Company's ability to successfully market HealthDesk OnLine to 
BCMA. In addition, the markets for the Company's proposed products are 
characterized by rapidly changing technology and evolving industry standards 
which could result in product obsolescence or short product life cycles. 
Accordingly, the ability of the Company to compete will be dependent upon the 
Company's ability to complete development and introduce HealthDesk OnLine 
into the marketplace in a timely manner, to continually enhance and improve 
its software and to successfully develop and market new products. There can 
be no assurance that the Company will be able to compete successfully, that 
competitors will not develop technologies or products that render the 
Company's products obsolete or less marketable or that the Company will be 
able to successfully enhance its products or develop new products. See 
"Business -- Competition." 

   8. Capacity Constraints; System Failure and Security Risks. The Company's 
operations will depend upon the capacity, reliability and security of its 
system infrastructure. The Company currently has limited system capacity and 
will be required to continually expand its system infrastructure to 
accommodate significant numbers of users and increasing amounts of healthcare 
information they may wish to access. Expansion of the Company's system 
infrastructure will require substantial financial, operational and management 
resources. The Company intends to use a portion of the proceeds of this 
offering to purchase computer equipment to expand system capacity. There can 
be no assurance that the Company will be able to expand its system 
infrastructure to meet potential demand on a timely basis, at a commercially 
reasonable cost, or at all. Failure by the Company to expand its system 
infrastructure on a timely basis would have a material adverse effect on the 
Company. In addition, the Company will be dependent upon Web browsers and 
third-party Internet and online service providers for access to the Company's 
services, hardware suppliers for prompt delivery, installation and service of 
computer equipment used to deliver the Company's services and on content 
providers to provide current healthcare information for use by consumers. 

   The Company's operations will also be dependent on the Company's ability 
to protect its computer equipment against damage from fire, earthquakes, 
power loss, telecommunications failures and similar events. The Company does 
not have earthquake insurance or redundant, multiple site capacity in the 
event of any such occurrence. The Company does maintain fire insurance with 
an aggregate limitation of $1 million and business interruption insurance 
with an aggregate limitation of $4 million. The Company's system 
infrastructure will be 

                                      9 
<PAGE>

also vulnerable to computer viruses, break-ins and similar disruptions from 
unauthorized tampering with the Company's computer systems. Computer viruses 
or problems caused by third parties could lead to material interruptions, 
delays or cessation in service to consumers. Inappropriate use of the 
Internet by third parties could also potentially jeopardize the security of 
confidential information stored in the computer systems of consumers. 
Security and privacy concerns of consumers may limit the Company's ability to 
develop a significant subscriber base. See "Use of Proceeds" and "Business -- 
Infrastructure, Operations and Technology." 

   9. Potential Liability and Insurance. In recent years, participants in the 
healthcare industry have been subject to an increasing number of lawsuits 
alleging malpractice, product liability and related legal theories, many of 
which involve large claims and significant defense costs. Due to the nature 
of its business, the Company could become involved in litigation regarding 
the healthcare information transmitted over its system with the risk of 
adverse publicity, significant defense costs and substantial damage awards. 
The Company has adopted policies and procedures intended to reduce the risk 
of claims, which include the provision of disclaimers in connection with its 
services. The Company does not currently maintain malpractice liability 
insurance. In addition, because healthcare information and materials may be 
downloaded and may be subsequently distributed to others, there is a 
potential that claims will be made against the Company for defamation, 
negligence, copyright or trademark infringement or other theories based on 
the nature and content of such materials. The Company also could be exposed 
to liability in connection with the selection of materials that may be 
accessible over its system. Claims could be made against the Company if 
material deemed inappropriate for viewing by children could be accessed. The 
Company carries an umbrella insurance policy with a limit of $4 million in 
the aggregate, general liability insurance with a limitation of $2 million in 
the aggregate and $1 million per occurrence and errors and omissions 
insurance with a limitation of $1 million. Nevertheless, the Company's 
insurance may not cover potential claims of this type or may not be adequate 
to cover liability that may be imposed or related defense costs. There can be 
no assurance that the Company will not face claims resulting in substantial 
liability for which the Company is partially or completely uninsured. Any 
partially or completely uninsured claim against the Company, if successful 
and of sufficient magnitude, would have a material adverse effect on the 
Company. See "Business -- Potential Liability and Insurance." 

   10. Government Regulation. The healthcare industry is subject to 
extensive, stringent and frequently changing federal and state regulation 
which is interpreted and enforced by regulatory authorities with broad 
discretion. Among other things, these regulations govern the provision of 
healthcare services and the marketing of medical devices. These regulations 
generally predate the development of products and services such as those 
offered and proposed to be offered by the Company and the application and 
enforcement of such regulations to the Company and its products and services 
is uncertain. However, certain of the statutes governing the provision of 
healthcare services could be construed by regulatory authorities to apply to 
the Company's proposed business activities. There can be no assurance that 
regulatory authorities do not or will not deem the Company's business 
activities to constitute the unlicensed practice of medicine. Furthermore, in 
the event the Company develops features which facilitate the input of data 
from medical devices directly into HealthDesk OnLine, it is possible that the 
United States Food and Drug Administration would require the Company and/or 
an equipment manufacturer to obtain pre-marketing clearance with respect to 
any such product. The process of obtaining and maintaining required 
regulatory approvals can be lengthy, expensive and uncertain. Even if 
regulatory approvals are obtained, a marketed product and its manufacturer 
are subject to continuing regulatory review, and discovery of previously 
unknown problems could result in restrictions on such product or 
manufacturer, including withdrawal of the product from the market. Amendments 
to or interpretation and enforcement of existing statutes or regulations, the 
adoption of new statutes or regulations or the development of new 
enhancements and features to HealthDesk OnLine could subject the Company to 
increased regulation and require the Company to alter methods of operation at 
costs which could be substantial. Failure to comply with applicable laws and 
regulations could subject the Company to civil remedies, including 
substantial fines, penalties and injunctions, as well as possible criminal 
sanctions. 

   Although there are currently few laws or regulations directly applicable 
to access to or commerce on the Internet, due to the increasing popularity 
and use of the Internet, it is possible that laws and regulations may be 
adopted with respect to the Internet, covering issues such as user privacy, 
pricing and characteristics and quality of products and services. The 
Telecommunications Reform Act of 1996, which was recently enacted, imposes 
criminal penalties on anyone who distributes obscene, lascivious or indecent 
communications on the Internet. 

                                      10 
<PAGE>

While the enforcement of such statute has been enjoined and is currently 
subject to challenge in the courts, the adoption of any such laws or 
regulations may limit the growth of the Internet, which could in turn 
decrease the demand for the Company's proposed products and services and 
increase the Company's cost of doing business. Inasmuch as the applicability 
to the Internet of the existing laws governing issues such as property 
ownership, libel and personal privacy is uncertain, any such new legislation 
or regulation or the application of existing laws and regulations to the 
Internet could have an adverse effect on the Company's business and 
prospects. See "Business -- Government Regulation." 

   11. Dependence on Third-Party Licenses. Substantially all of the 
information content currently included in HealthDesk OnLine has been licensed 
by the Company from unaffiliated third parties. The licenses granted to the 
Company are subject to termination on relatively short notice. Although the 
Company believes that similar healthcare information is available from 
multiple sources, in the event of any termination of such licenses, the 
Company may be required to independently develop information content or 
license such information content from other providers. There can be no 
assurance that the Company would be able to do so in a timely manner, upon 
acceptable terms and conditions, or at all. The failure to obtain current 
healthcare information for use by consumers on a timely and competitive basis 
could have a material adverse effect on the Company. See "Business -- 
Infrastructure, Operations and Technology." 

   
   12. Dependence on Limited Customer Base. To date, the Company's revenues 
have been derived from a limited number of customers. Two customers accounted 
for approximately 76% and 5%, respectively, of revenues in 1994 and 40% and 
56%, respectively, in 1995. Additionally, one customer accounted for 
approximately 96% and 92%, respectively, of revenues for the nine months 
ended September 30, 1995 and 1996. Although the Company is not currently 
generating meaningful revenues, in the event that the Company is able to 
successfully commercialize HealthDesk OnLine or obtain third party funding of 
the costs of developing new software modules, there can be no assurance that 
the Company will not continue to be dependent on a limited customer base for 
all or a substantial portion of its revenues. The Company's letter of intent 
with MIIX contemplates that the Company would grant to MIIX a right of first 
refusal to fund the development of additional software modules. See "Business 
- -- Potential Markets and Marketing." 
    

   13. Industry Factors; Lengthy Sales Cycle. The healthcare industry has 
experienced significant changes in recent years, primarily due to rising 
healthcare costs. Healthcare payers are increasingly challenging the price of 
medical services and products, which have had and could continue to have a 
significant effect on the procurement practices of healthcare providers, 
generally causing them to be more selective in the purchase of new 
technologies. Several proposals have been made by federal and state 
government officials that may lead to substantial healthcare reform, 
including the implementation of government-directed national healthcare 
system and stringent healthcare cost containment measures. Adoption of such 
proposed measures could result in reduction or deferral of capital 
expenditures by potential customers. Also, there has been substantial 
consolidation in the healthcare industry in recent years, which could make it 
more difficult for the Company to achieve market acceptance by larger 
potential customers. Moreover, a sponsoring organization's decision to 
purchase new products and technology is often lengthy and requires the 
approval of a significant number of administrators. The period in which a 
sponsoring organization distributes the Company's software to its members may 
also be lengthy, depending upon the level of acceptance and usage by its 
members, which could delay the Company's plans in particular markets. See 
"Business." 

   14. Proprietary Information. Although the Company intends to evaluate the 
feasibility of obtaining patent protection for certain aspects of HealthDesk 
OnLine, the Company does not hold any patents or registered copyrights. The 
Company regards certain computer software it has developed for HealthDesk 
OnLine as proprietary and attempts to protect it with copyrights, trade 
secret laws, proprietary rights agreements and internal nondisclosure 
agreements and safeguards. However, such methods may not afford complete 
protection and there can be no assurance that others will not independently 
develop know-how or obtain access to the Company's know-how or software 
codes, concepts, ideas and documentation. Furthermore, there can be no 
assurance that nondisclosure agreements with the Company's employees will 
adequately protect the Company's trade secrets. Although the Company believes 
that its proposed products do not and will not infringe patents or violate 
proprietary rights of others, it is possible that infringement of existing or 
future patents or proprietary rights of others have occurred or may occur. In 
the event the Company's proposed products infringe patents or proprietary 

                                      11 
<PAGE>

rights of others, the Company may be required to modify the design of its 
proposed products or obtain a license. There can be no assurance that the 
Company will be able to do so in a timely manner, upon acceptable terms and 
conditions or at all. The failure to do any of the foregoing could have a 
material adverse effect upon the Company. In addition, there can be no 
assurance that the Company will have the financial or other resources 
necessary to enforce or defend a patent infringement action and the Company 
could, under certain circumstances, become liable for damages, which also 
could have a material adverse effect on the Company. See "Business -- 
Proprietary Information and Trademarks." 

   15. Dependence on Key Personnel. The success of the Company will be 
dependent on the personal efforts of Peter O'Donnell, its President and Chief 
Executive Officer, Dr. Molly Coye, its Executive Vice President, Timothy S. 
Yamauchi, its Chief Financial Officer, and other key personnel. The loss of 
the services of such individuals could have a material adverse effect on the 
Company's business and prospects. The Company has obtained "key-person" 
insurance on the life of each of Mr. O'Donnell, Dr. Coye and Mr. Yamauchi in 
the amounts of $2 million, $2 million and $1 million, respectively. The 
success of the Company is also dependent upon its ability to hire and retain 
additional qualified management, marketing, technical, financial and other 
personnel. Competition for qualified personnel is intense and there can be no 
assurance that the Company will be able to hire or retain qualified 
personnel. Any inability to attract and retain qualified management and other 
personnel could have a material adverse effect on the Company. See 
"Management." 

   
   16. Control by Management. Upon consummation of this offering, the 
officers and directors of the Company will beneficially own, in the 
aggregate, approximately 44.0% of the outstanding shares of Common Stock 
(assuming no exercise of the Warrants). Accordingly, such persons, acting 
together, will be in a position to exercise significant influence over the 
Company's affairs. See "Management" and "Principal Shareholders." 
    

   17. Potential Conflicts of Interest. The Company has entered into various 
transactions with certain of its directors and principal shareholders and 
their affiliates, which could result in potential conflicts of interest. Mr. 
John Pappajohn and Edgewater, principal shareholders of the Company, have 
from time to time made loans to the Company, and the Company has entered into 
a marketing agreement with an entity of which Mr. Pappajohn is a director and 
principal shareholder. The Company believes that all of such transactions and 
arrangements were fair and reasonable to the Company and were on terms no 
less favorable than could have been obtained from unaffiliated third parties. 
There can be no assurance, however, that future transactions or arrangements 
between the Company and its affiliates will continue to be advantageous to 
the Company, that conflicts of interest will not arise with respect thereto, 
or that if conflicts do arise, they will be resolved in a manner favorable to 
the Company. Any such future transactions will be on terms no less favorable 
to the Company than could be obtained from unaffiliated parties and will be 
approved by a majority of the independent and disinterested members of the 
Board of Directors, outside the presence of any interested directors and, to 
the extent deemed appropriate by the Board of Directors, the Company will 
obtain shareholder approval or fairness opinions in connection with any such 
transaction. See "Certain Transactions." 

   
   18. Benefits to Related Parties. The Company intends to use a portion of 
the proceeds to repay the entire principal amount of and accrued interest on 
the Bridge Notes. John Pappajohn, a director and principal shareholder of the 
Company, and Edgewater, a principal shareholder of the Company which is 
affiliated with James Gordon, a director of the Company, each purchased 
$100,000 principal amount of Bridge Notes pursuant to the Bridge Financing. 
The Company intends to use approximately 2.6% of the net proceeds to repay 
such Bridge Notes on the consummation of this offering. In addition, the 
Company may use a portion of the proceeds of this offering allocated to 
working capital to pay compensation of its executive officers (which is 
expected to be approximately $580,000, or approximately 7.6% of the net 
proceeds, during the twelve months following this offering). See "Use of 
Proceeds" and "Certain Transactions." 

   19. Immediate and Substantial Dilution. Investors in this offering will 
incur immediate and substantial dilution of $3.79 (76%) per share between the 
adjusted net tangible book value per share after this offering and the 
initial public offering price of $5.00 per share. The current shareholders of 
the Company acquired their Common Stock at an average price of $1.27 per 
share, substantially below the initial public offering price. Accordingly, to 
the extent the Company continues to incur losses, investors in this offering 
will bear a disproportionate risk of such losses. See "Dilution" and 
"Underwriting." 
    

   20. Outstanding Options. As of the date of this Prospectus, the Company 
had outstanding options to purchase an aggregate of 768,050 shares of Common 
Stock at exercise prices ranging from $1.04 to $5.00. Exer- 

                                      12 
<PAGE>

   
cise of any of the foregoing options will have a dilutive effect on the 
Company's shareholders. Furthermore, the terms upon which the Company may be 
able to obtain additional equity financing may be adversely affected, since 
the holders of the options can be expected to exercise them, if at all, at a 
time when the Company would, in all likelihood, be able to obtain any needed 
capital on terms more favorable to the Company than those provided in the 
options. See "Management -- 1994 Stock Option Plan." 
    

   21. No Dividends. To date, the Company has not paid any cash dividends on 
its Common or Preferred Stock and does not expect to declare or pay dividends 
on the Common Stock in the foreseeable future. See "Dividend Policy." 

   22. Authorized Preferred Stock. The Company's Restated Articles of 
Incorporation authorizes the Company's Board of Directors to issue 1,800,000 
shares of "blank check" Preferred Stock and to fix the rights, preferences, 
privileges and restrictions, including voting rights, of these shares, 
without further shareholder approval. The rights of the holders of Common 
Stock will be subject to and may be adversely affected by the rights of 
holders of any Preferred Stock that may be issued in the future. The ability 
to issue Preferred Stock without shareholder approval could have the effect 
of making it more difficult for a third party to acquire a majority of the 
voting stock of the Company thereby delaying, deferring or preventing a 
change in control of the Company. The Company's Series A Preferred Stock will 
convert into Common Stock upon the consummation of this offering. See 
"Description of Securities." 

   
   23. Shares Eligible for Future Sale, Registration Rights. Upon 
consummation of this offering, the Company will have 5,489,720 shares of 
Common Stock outstanding, of which 2,200,000 shares, consisting of 1,800,000 
shares offered hereby and, subject to certain contractual restrictions 
described below, the 400,000 shares being offered by the Selling 
Shareholders, will be freely tradable without restriction or further 
registration under the Securities Act. All of the remaining 3,289,720 shares 
of Common Stock outstanding are "restricted securities," as that term is 
defined in Rule 144 promulgated under the Securities Act, and in the future 
may be sold only pursuant to an effective registration statement under the 
Securities Act, in compliance with the exemption provisions of Rule 144 or 
pursuant to another exemption under the Securities Act. Of the 3,289,720 
restricted shares, an aggregate of 237,000 shares will be eligible for sale, 
without registration, under Rule 144 (subject to the contractual restrictions 
described below), on the date of this Prospectus, and 417,000 shares will be 
eligible (subject to certain volume limitations and the contractual 
restrictions described below) commencing 90 days from the date of this 
Prospectus. All of the Company's officers, directors and security holders 
(except for the holders of 42,000 shares of Common Stock) have agreed not to 
sell or dispose of any of their securities of the Company for a period of 
eighteen months from the date of this Prospectus without the Underwriter's 
prior written consent. The Company has also granted certain demand and 
"piggyback" registration rights to the holders of an aggregate of 1,741,600 
shares of Common Stock (including 400,000 shares issued in connection with 
the Bridge Financing). The Company has obtained a waiver of registration 
rights to the extent such rights would have been applicable to this offering. 
No prediction can be made as to the effect, if any, that sales of such 
securities or the availability of such securities for sale will have on the 
market prices prevailing from time to time. However, even the possibility 
that a substantial number of the Company's securities may be sold in the 
public market may adversely affect prevailing market prices for the Common 
Stock and Warrants and could impair the Company's ability to raise capital 
through the sale of its equity securities. See "Description of Securities," 
"Shares Eligible for Future Sale," "Underwriting" and "Selling Shareholders 
and Plan of Distribution." 

   24. Absence of Public Market; Possible Volatility of Market Price of 
Common Stock and Warrants. Prior to this offering, there has been no public 
trading market for the Common Stock or Warrants. Consequently, the initial 
public offering price has been determined by negotiation between the Company 
and the Underwriter and is not necessarily related to the Company's asset 
value, net worth or other criteria of value. There can be no assurance that a 
regular trading market for the Common Stock or Warrants will develop after 
this offering or that, if developed, it will be sustained. The market price 
of the Common Stock and Warrants following this offering may be highly 
volatile as has been the case with securities of other small capitalization 
companies. Factors such as the Company's operating results, announcements of 
developments related to the Company's business and the introduction of new 
products or product enhancements by the Company or its competitors may have a 
significant impact in the market price of the Common Stock and Warrants. In 
addition, in recent years the stock market in general, and the market for 
shares of small capitalization stocks in particular, have experienced wide 
price fluctuations which have often been unrelated to the operating 
performance of such companies. See "Underwriting." 
    

                                      13 
<PAGE>

   
   25. Possible Delisting of Securities from NASDAQ System; Disclosure 
Relating to Low-Priced Stocks. The Common Stock and Warrants will be quoted 
on NASDAQ SmallCap Market ("NASDAQ") upon the consummation of this offering. 
However, in order to continue to be included in NASDAQ, a company must 
maintain $2,000,000 in total assets, a $200,000 market value of the public 
float and $1,000,000 in total capital and surplus. In addition, continued 
inclusion requires two market makers and a minimum bid price of $1.00 per 
share; provided, however, that if a company falls below such minimum bid 
price, it will remain eligible for continued inclusion in NASDAQ if the 
market value of the public float is at least $1,000,000 and the Company has 
$2,000,000 in capital and surplus. NASDAQ has recently proposed new 
maintenance criteria which, if implemented, would eliminate the exception to 
the $1.00 per share minimum bid price and require, among other things, 
$2,000,000 in net tangible assets, $1,000,000 market value of the public 
float and adherence to certain corporate governance provisions. Failure to 
meet these maintenance criteria in the future may result in the delisting of 
the Company's securities from NASDAQ and trading, if any, in the Company's 
securities would thereafter be conducted in the non-NASDAQ over-the-counter 
market. As a result of such delisting, an investor may find it more difficult 
to dispose of, or to obtain accurate quotations as to the market value of, 
the Company's securities. In addition, if the Common Stock were delisted from 
trading on NASDAQ and the trading price of the Common Stock was less than 
$5.00 per share, trading in the Common Stock would also be subject to certain 
rules promulgated under the Exchange Act, which require additional disclosure 
by broker-dealers in connection with any trades involving a stock defined as 
a penny stock (generally, any non-NASDAQ equity security that has a market 
price of less than $5.00 per share, subject to certain exceptions). Such 
rules require the delivery, prior to any penny stock transaction, of a 
disclosure schedule explaining the penny stock market and the risks 
associated therewith, and impose various sales practice requirements on 
broker-dealers who sell penny stock to persons other than established 
customers and accredited investors (generally institutions). For these types 
of transactions, the broker-dealer must make a special suitability 
determination for the purchaser and have received the purchaser's written 
consent to the transactions prior to sale. The additional burdens imposed 
upon broker-dealers by such requirements may discourage broker-dealers from 
effecting transactions in the Common Stock, which could severely limit the 
market liquidity of the Common Stock and the ability of purchasers in this 
offering to sell the Common Stock in the secondary market. 
    

   26. Forward Looking Statements. The statements which are not historical 
facts contained in this Prospectus are forward looking statements that 
involve risks and uncertainties, including the risks discussed above. The 
Company's actual results may differ materially from the results discussed in 
such forward looking statements. 

   
   27. Potential Adverse Effect of Warrant Redemption. The Warrants are 
subject to redemption by the Company, upon the consent of the Underwriter, at 
any time commencing on        , 1998, upon notice of not less than 30 days, 
at a price of $.10 per Warrant, provided that the closing bid quotation of 
the Common Stock on all 30 trading days ending on the third day prior to the 
day on which the Company gives notice has been at least 150% (currently 
$7.50, subject to adjustment) of the then effective exercise price of the 
Warrants. Redemption of the Warrants could force the holders to exercise the 
Warrants and pay the exercise price at a time when it may be disadvantageous 
for the holders to do so, to sell the Warrants at the then current market 
price when they might otherwise wish to hold the Warrants, or to accept the 
redemption price, which is likely to be substantially less than the market 
value of the Warrants at the time of redemption. See "Description of 
Securities -- Redeemable Warrants." 

   28. Possible Inability to Exercise Warrants. The Company intends to 
qualify the sale of the Common Stock and the Warrants in a limited number of 
states. Although certain exemptions in the securities laws of certain states 
might permit the Warrants to be transferred to purchasers in states other 
than those in which the Warrants were initially qualified, the Company will 
be prevented from issuing Common Stock in such states upon the exercise of 
the Warrants unless an exemption from qualification is available or unless 
the issuance of Common Stock upon exercise of the Warrants is qualified. The 
Company may decide not to seek or may not be able to obtain qualification of 
the issuance of such Common Stock in all of the states in which the ultimate 
purchasers of the Warrants reside. In such a case, the Warrants held by 
purchasers will expire and have no value if such Warrants cannot be sold. 
Accordingly, the market for the Warrants may be limited because of these 
restrictions. Further, a current prospectus covering the Common Stock 
issuable upon exercise of the Warrants must be in effect before the Company 
may accept Warrant exercises. There can be no assurance the Company will be 
able to have a prospectus in effect when this Prospectus is no longer 
current, notwithstanding the Company's commitment to use its best efforts to 
do so. See "Description of Securities -- Redeemable Warrants."

                               USE OF PROCEEDS 

   
   The net proceeds to the Company from the sale of the shares of Common 
Stock and Warrants offered hereby are estimated to be $7,612,000 ($8,753,800 
if the Underwriter's over-allotment option is exercised in full). The Company 
expects to use the net proceeds during the twelve months following this 
offering approximately as follows:

(1) Includes anticipated costs and expenses associated with marketing 
    activities, including compensation and sales incentives for three 
    existing and up to seven additional sales and marketing personnel, and 
    preparation of sales documents and brochures. See "Business -- Potential 
    Markets and Marketing." 

(2) Represents amounts to be used for the repayment of the entire $2,000,000 
    principal amount of the Bridge Notes and estimated accrued interest 
    thereon. The Bridge Notes bear interest at the rate of 9% per annum and 
    are repayable on the earlier of the consummation of this offering or 
    October 11, 1997. The Company used the proceeds of the Bridge Financing 
    principally in connection with the repayment of approximately $583,000 of 
    indebtedness to Quantum and expenses associated with product development 
    and sales and marketing. See "Management's Discussion and Analysis of 
    Financial Condition and Results of Operations -- Liquidity." 

(3) Represents anticipated costs associated with system refinement and 
    enhancement, the cost of hardware and estimated salaries of eleven 
    existing and up to seven additional technical personnel, including 
    consultants. See "Business -- Product Development." 

(4) Represents anticipated costs associated with the purchase of computer 
    hardware for servers and related telecommunications equipment used to 
    support the Company's system infrastructure. See "Business -- 
    Infrastructure, Operations and Technology." 

(5) Working capital will be used, among other things, to pay compensation to 
    executive officers (which is anticipated to be approximately $580,000 
    during the twelve months following this offering) rent, trade payables, 
    license fees for content and software, professional fees and other 
    operating expenses. See "Management." 

   
   If the Underwriter exercises its over-allotment option in full, the 
Company will realize additional net proceeds of $1,341,800 which will be 
added to working capital. 
    

   Based on currently proposed plans and assumptions relating to its 
operations (including the timetable of, and costs associated with, product 
development and commercialization), the Company believes that the proceeds of 
this offering will be sufficient to satisfy the Company's contemplated cash 
requirements for at least twelve months following the consummation of this 
offering. In the event the Company's plans change or its assumptions change 
or prove to be inaccurate or the proceeds of this offering prove to be 
insufficient to fund operations (due to unanticipated expenses, delays, 
problems or otherwise), the Company may find it necessary or desirable to 
reallocate a portion of the proceeds within the above described categories, 
use proceeds for other purposes, seek additional financing or curtail its 
operations. There can be no assurance that additional financing will be 
available to the Company on commercially reasonable terms, or at all. See 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations." 

   Proceeds not immediately required for the purposes described above will be 
invested principally in United States government securities, short-term 
certificates of deposit, money market funds or other short-term interest- 
bearing investments.

                               DIVIDEND POLICY 

   The Company has paid no cash dividends on its Common Stock since its 
incorporation. The Company intends to retain any earnings for use in its 
business and therefore does not anticipate paying any cash dividends in the 
foreseeable future.

                                   DILUTION 

   The difference between the initial public offering price per share of 
Common Stock and the adjusted net tangible book value per share after this 
offering constitutes the dilution to investors in this offering. Net tangible 
book value per share of Common Stock is determined by dividing the net 
tangible book value of the Company (total tangible assets less total 
liabilities) on such date, by the number of shares of Common Stock. 

   
   At September 30, 1996, the Company had a negative net tangible book value 
of ($1,153,582) or ($.54) per share. After giving retroactive effect to the 
Pro Forma Adjustments, pro forma net tangible book value of the Company at 
September 30, 1996 would have been $120,418, or $.03 per share. After giving 
effect to the sale of the shares of Common Stock and Warrants offered by the 
Company hereby and the receipt of the estimated net proceeds therefrom (less 
underwriting discounts and commissions and estimated expenses of this 
offering), the adjusted net tangible book value of the Company as of 
September 30, 1996 would have been approximately $6,678,418 or $1.21 per 
share. This represents an immediate increase in net tangible book value of 
$1.18 per share to existing shareholders and an immediate dilution of $3.79 
per share to new investors. The following table illustrates this dilution to 
new investors on a per share basis:

   The above table assumes no exercise of the Underwriter's over-allotment 
option or outstanding options. If the Underwriter's over-allotment option is 
exercised in full, the new investors will have paid $10,350,000 for 2,070,000 
shares of Common Stock, representing approximately 68.9% of the total 
consideration for 35.9% of the total number of shares of Common Stock 
outstanding. In addition, the above table also assumes no exercise of 
outstanding stock options or the Warrants. As of the date of this Prospectus, 
there are outstanding stock options to purchase an aggregate of 768,050 
shares of Common Stock at exercise prices ranging from $1.04 to $5.00. To the 
extent that stock options are exercised at prices below the public offering 
price there will be further dilution to new investors. See "Management--1994 
Stock Option Plan" and "Underwriting."

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

OVERVIEW 

   The Company was organized in August 1992 and is still in the development 
stage. Since its inception, the Company has been engaged primarily in product 
development activities. The Company's initial product was introduced in early 
1993 and has not yet proven to be commercially viable. 

   The Company has not yet generated any meaningful revenues, and will not 
generate any meaningful revenues until after the Company successfully 
completes development and market testing of HealthDesk OnLine and attracts 
and retains a significant number of subscribers. For the period August 28, 
1992 (inception) to September 30, 1996, the Company incurred a cumulative net 
loss of approximately $4,555,000. Since September 30, 1996, the Company has 
continued to incur increasing and significant losses and anticipates that it 
will continue to incur significant losses until, at the earliest, the Company 
generates sufficient revenues to offset the substantial up-front expenditures 
and operating costs associated with developing and commercializing its 
proposed products. The Company will also incur non-recurring charges related 
to the Bridge Financing of approximately $1,054,000 upon the consummation of 
this offering. There can be no assurance that the Company will be able to 
attract and retain a sufficient number of subscribers to generate meaningful 
revenues or achieve profitable operations or that HealthDesk OnLine will 
prove to be commercially viable. 

   The Company's independent accountants have included an explanatory 
paragraph in their report on the Company's financial statements as to the 
ability of the Company to continue as a going concern. This offering is an 
integral part of the Company's plan to continue as a going concern. See Note 
1 to Notes to Financial Statements. 

   Software development costs (consisting primarily of salaries and related 
expenses) incurred prior to establishing technological feasibility are 
expensed in accordance with Financial Accounting Standards Board (FASB) 
Statement No. 86. In accordance with FASB 86, the Company will capitalize 
software development costs at such time as the technological feasibility of 
the product has been established. 

RESULTS OF OPERATIONS 

   Nine Months Ended September 30, 1995 Compared to Nine Months Ended 
September 30, 1996. 

   Revenue decreased by 97.2% from $223,432 for the nine months ended 
September 30, 1995 to $6,170 for the nine months ended September 30, 1996. 
The decrease in revenues was principally due to the lack of development fees 
during the period, which reflects the Company's shift in focus from the 
development of specific disease software modules to the development of 
HealthDesk OnLine. 

   Product development costs increased by 209.0% from $386,409 for the nine 
months ended September 30, 1995 to $1,194,038 for the nine months ended 
September 30, 1996. This increase was primarily attributable to increased 
additional programming and development personnel, including consultants 
engaged in developing HealthDesk OnLine. 

   Sales and marketing costs increased 318.7% from $199,757 for the nine 
months ended September 30, 1995 to $836,291 for the nine months ended 
September 30, 1996. This increase was primarily attributable to costs 
associated with additional sales and marketing personnel engaged in marketing 
HealthDesk OnLine commencing in the fourth quarter of 1995 and related 
marketing expenses. 

   General and administrative costs increased by 42.2% from $395,853 for the 
nine months ended September 30, 1995 to $562,986 for the nine months ended 
September 30, 1996. This increase was primarily attributable to salaries of 
new management personnel. Costs also increased as a result of a non-recurring 
write-off of deferred offering costs accrued during the period and expenses 
associated with the Company's relocation to larger facilities. 

   Other (income) expense, net decreased by 55.2% from $22,407 for the nine 
months ended September 30, 1995 to $10,046 for the nine months ended 
September 30, 1996. This decrease was attributable to increased interest 
income as a result of the receipt of the proceeds from the sale of Series A 
Preferred Stock in December 1995. 

   As a result of the foregoing, the Company incurred a net loss of 
$2,597,791 for the nine months ended September 30, 1996, as compared to a net 
loss of $781,594 for the prior comparable period. 

                                      19 
<PAGE>

   Year Ended December 31, 1994 Compared with Year Ended December 31, 1995. 

   Revenue decreased by 43.6% from $397,240 for the year ended December 31, 
1994 to $224,011 for the year ended December 31, 1995. This decrease was 
primarily attributable to a decrease in development fee revenues. During 
1995, the Company focused its efforts on the development of HealthDesk OnLine 
and reduced its marketing and sales efforts relating to its HealthDesk 
product. 

   Product development costs increased by 194.4% from $231,243 for the year 
ended December 31, 1994 to $680,886 for the year ended December 31, 1995. The 
increase in expenditures was principally related to the expansion of the 
programming staff and associated costs related to the development of 
HealthDesk OnLine. 

   Sales and marketing costs increased by 58.5% from $220,243 for the year 
ended December 31, 1994 to $349,133 for the year ended December 31, 1995. 
This increase resulted primarily from the hiring of additional marketing 
personnel and associated sales and marketing efforts in connection with 
HealthDesk OnLine during the fourth quarter of 1995. 

   General and administrative costs increased by 240.6% from $170,598 for the 
year ended December 31, 1994 to $581,043 for the year ended December 31, 
1995. This increase was primarily attributable to the hiring of new 
management personnel and severance costs relating to prior management and, to 
a lesser extent, increased professional fees. 

   Other (income) expense, net increased by 327.3% from $11,378 for the year 
ended December 31, 1994 to $48,622 for the year ended December 31, 1995. This 
increase was primarily attributable to increased interest expense as a result 
of higher levels of borrowings. 

   As a result of the foregoing, the Company incurred a net loss of 
$1,436,473 for the year ended December 31, 1995, as compared to a net loss of 
$237,022 for the prior comparable year. 

LIQUIDITY AND CAPITAL RESOURCES 

   The Company's primary capital requirements will be to fund the development 
and commercialization of HealthDesk OnLine. The Company has historically 
financed its operations through the issuance of debt and equity securities. 

   Prior to the issuance of 400,000 shares of Common Stock in the Bridge 
Financing, the Company had issued an aggregate of 2,130,120 shares of Common 
Stock resulting in net proceeds of $1,221,355. The foregoing excludes an 
aggregate of (i) 100,000 shares of Common Stock issuable upon conversion of 
$500,000 principal amount of indebtedness on the date of this Prospectus and 
(ii) 1,059,600 shares of Series A Preferred Stock, each of which will convert 
into one share of Common Stock upon the consummation of this offering. 

   In May 1994, the Company borrowed an aggregate of $500,000 from Quantum, 
evidenced by a promissory note bearing interest at the rate of 7% per annum. 
The Company repaid such note from proceeds of the Bridge Financing. 

   During the period from June through September 1995, the Company issued 6% 
convertible promissory notes in the aggregate principal amount of $800,000 to 
John Pappajohn and Edgewater, principal shareholders of the Company. The 
notes were converted into an aggregate of 768,000 shares of Common Stock in 
September 1995. See "Certain Transactions." 

   In December 1995, Mr. Pappajohn exercised an option to purchase 96,000 
shares of Common Stock for an aggregate exercise price of $100,000. See 
"Certain Transactions." 

   In December 1995 and February 1996, the Company completed a private 
placement of an aggregate of 1,059,600 shares of Series A Preferred Stock and 
received net proceeds of approximately $2,183,000. Each share of Series A 
Preferred Stock automatically converts into one share of Common Stock upon 
consummation of this offering. 

   In July and August 1996, the Company issued an aggregate of $500,000 
principal amount 8% promissory notes to Mr. Pappajohn and Edgewater. Such 
notes will automatically convert into 100,000 shares of Common Stock on the 
date of this Prospectus. See "Certain Transactions." 

   In October 1996, the Company consummated the Bridge Financing pursuant to 
which it issued $2,000,000 principal amount of Bridge Notes and 400,000 
shares of Common Stock. The Company intends to use a portion of the proceeds 
of this offering to repay the entire principal amount of and accrued interest 
on the Bridge Notes. 

                                      20 
<PAGE>

   Since its inception, the Company has engaged primarily in research and 
development and has generated limited revenues. The Company expects to incur 
significant up-front expenses in connection with product development and 
commercialization (including the payment of salaries for management, 
technical, marketing and other personnel), which will result in significant 
losses for the foreseeable future. 

   The Company's capital requirements relating to the development and 
commercialization of HealthDesk OnLine have been and will continue to be 
significant. Other than as described in this Prospectus, the Company has no 
material commitments for capital expenditures. For the period August 28, 1992 
(inception) to September 30, 1996, the Company had capital expenditures of 
approximately $660,000 relating primarily to computer equipment. The Company 
has committed to pay license fees for content and software aggregating 
approximately $190,000 prior to December 31, 1996. 

   The Company is dependent on the proceeds of this offering or other 
financing in order to continue in business and develop and commercialize its 
proposed products. Based on currently proposed plans and assumptions relating 
to its operations (including the timetable of, and costs associated with, 
product development and commercialization), the Company believes that the 
proceeds of this offering will be sufficient to satisfy its contemplated cash 
requirements for at least twelve months following the consummation of this 
offering. In the event that the Company's plans change, its assumptions 
change or prove to be inaccurate or if the proceeds of this offering prove to 
be insufficient to fund operations (due to unanticipated expenses, technical 
difficulties, problems or otherwise), the Company would be required to seek 
additional financing sooner than currently anticipated. There can be no 
assurance that the proceeds of this offering will be sufficient to permit the 
Company to successfully develop and commercialize HealthDesk OnLine or that 
any assumptions relating to the Company's operations will prove to be 
accurate. To the extent that the proceeds of this offering are not sufficient 
to enable the Company to generate meaningful revenues or achieve profitable 
operations, the inability to obtain additional financing will have a material 
adverse effect on the Company, including possibly requiring the Company to 
significantly curtail or cease its operations. 

   In addition, any implementation of the Company's business plans subsequent 
to the twelve month period following this offering may require proceeds 
greater than the proceeds of this offering or otherwise currently available 
to the Company. The Company may determine, depending upon the opportunities 
available to it, to seek additional debt or equity financing to fund 
operations. To the extent that the Company finances operations through the 
issuance of additional equity securities, any such issuance would result in 
dilution to the interests of the Company's shareholders. Additionally, to the 
extent that the Company incurs indebtedness or issues debt securities in 
connection with funding operations, the Company will be subject to all of the 
risks associated with incurring substantial indebtedness, including the risks 
that interest rates may fluctuate and cash flow may be insufficient to pay 
principal and interest on any such indebtedness. There can be no assurance 
that any additional financing will be available to the Company on 
commercially reasonable terms, or at all.

                                   BUSINESS 

BACKGROUND 

   The Company, a development stage company, is engaged in designing, 
developing and marketing HealthDesk OnLine, a healthcare management and 
information system which enables consumers to take a more active role in 
their personal and family health. HealthDesk OnLine features easy-to-use 
Windows-based software designed to develop personal medical records and 
health management programs and access educational, health related information 
from the Company's private Website and over the Internet. The Company's 
proposed system is intended to lower the cost and improve the quality and 
accessibility of healthcare by promoting preventive maintenance and patient 
compliance and permitting electronic mail communications between consumers 
and healthcare providers and payers. HealthDesk OnLine is being developed in 
response to perceived market opportunities arising from increasing efforts of 
industry participants to stem the escalating cost of healthcare. 

MARKET TRENDS 

   According to the Congressional Budget Office, annual healthcare 
expenditures in the United States have grown from approximately $470 billion 
in 1982 to more than $1 trillion in 1995, representing more than 14% of the 
gross national product. It is estimated that more than $270 billion is spent 
on the treatment and related costs of chronic diseases such as diabetes, 
HIV/AIDS, cancer, cardio-vascular disease, obstructive pulmonary disease and 
asthma. In response to escalating healthcare costs, federal and state 
government authorities have increasingly emphasized stringent cost 
containment measures, and healthcare payers and providers have focused on 
programs which reduce the costs of providing medical products and services 
and managing chronic diseases. Inasmuch as the Company is a development stage 
company seeking to develop and commercialize a new product, aggregate 
expenditures on healthcare in general and chronic diseases in particular, may 
not be directly relevant to the Company's current prospects. 

   The Company believes that the broad range of capabilities combined in 
HealthDesk OnLine, including the system's desktop and online functionality, 
and the system's ability to link consumers with healthcare payers and 
providers, differentiate HealthDesk OnLine from competitive products and make 
it attractive to potential sponsoring organizations seeking to contain 
healthcare costs. The Company believes that the following key trends will 
contribute favorably to expected demand for HealthDesk OnLine: 

   o Proliferation of Managed Care and Competitive Pressures: The healthcare 
     industry has undergone significant transformation in recent years. With 
     the proliferation of managed care, employers, consumers and other 
     purchasers of healthcare have greater access to an increasing number of 
     managed care organizations which are experiencing competitive pressures 
     to differentiate their healthcare product and service offerings to 
     attract and retain members. 

   o Continuing Penetration of Computers and Modems in the Home: An 
     increasing percentage of computer owners also own modems, which are 
     being pre-installed in a growing number of new computers. The Software 
     Publishers Association estimates that approximately 33.9 million or 34% 
     of households in the United States owned a personal computer as of 1995, 
     of which approximately 70% also owned a modem. The Company believes that 
     this growth is accompanied by increasing use of computers for 
     communications such as facsimile transmissions and electronic mail. 

   o Growth of the Informational and Commercial Applications and Resources of 
     the Internet: Use of the Internet has grown rapidly since its 
     commercialization in the early 1990s. An increasing number of servers 
     and Websites are being connected to the Internet, making available 
     educational and healthcare text, graphics and audio and video 
     information which may be accessed by consumers. Traditional and emerging 
     Internet applications, including electronic mail and the World Wide Web, 
     are also increasing in popularity. Internet use is also being promoted 
     by the development of user-friendly navigation and search tools designed 
     to simplify consumer access to the Internet's resources. 

   o Rapidly Changing Consumer Demands: The Company believes that demand for 
     healthcare information and services is increasing as the "baby boomer" 
     generation reaches its peak healthcare consuming years. Consumers are 
     assuming greater responsibility for their healthcare decisions, seeking 
     as much informa- 

                                      22 
<PAGE>

     tion as possible when choosing a health plan, doctor or treatment. 
     According to the New York Times, the number of health related sites on 
     the World Wide Web has grown significantly, reflecting the growing 
     demand from consumers for information to help them make more informed 
     choices about their own care. 

HEALTHDESK ONLINE 

   HealthDesk OnLine software contains several modules for recording 
information (Health History and Records) and several modules which also 
monitor the state of the user's lifestyle and efforts at preventive 
maintenance (Health Diaries). These modules allow users to create an 
extensive database that can be appended, searched, reviewed and printed at 
any time. The Company's software also contains modules which provide access 
to healthcare information from the Company's private Website and over the 
Internet (Gateways and Services). 

   Health History and Records 

   Background. The background module is designed to store basic information, 
such as name, age, sex, address, phone number, social security number, 
insurance carrier and blood type of a user. 

   Personal Conditions. The personal conditions module is designed to track 
doctor and hospital visits and other important health events, including 
medications, vaccinations, charges, out-of-pocket expenses and insurance 
reimbursements. 

   Family Health. The family health module is designed to track health 
information relating to family members that could affect the health profile 
of a user. 

   Medication History. The medication history module is designed to track 
medication usage, including information relating to dosage, frequency, cost 
and prescribing physician. 

   Supplies. The supplies module is designed to track health-related 
supplies, such as bandages or syringes used on a regular basis, inventory and 
costs. 

   Finances. The finances module is designed to collect and store information 
from other health records modules to enable a user to organize and track 
comprehensive medical costs. 

   Health Diaries 

   Exercise. The exercise module is designed to track exercise activities, 
including aerobics, running, walking, weight lifting, swimming and bicycling. 

   Heart Health. The heart health module is designed to track serum 
cholesterol levels, blood pressure and pulse. 

   Weight. The weight module is designed to track body fat, calorie intake, 
calories burned and weight. 

   Vital Signs. The vital signs module is designed to track blood pressure, 
weight, height, pulse and basal temperature. 

   Medications. The medications module is designed to track the date and time 
medication is taken by the user. 

   Nutrition. The nutrition module is designed to track caloric intake and 
calories burned, as well as fat, protein and carbohydrate consumption. 

   Each module includes a series of illustrated diagrams, which demonstrate 
important features relating to a healthcare topic. HealthDesk OnLine software 
permits a user to add other categories and variables not listed on a module. 
Readings can be edited, summarized and graphed on-screen for detecting trends 
and patterns in daily health activities. 

   Gateways and Services 

   Library. The HealthDesk OnLine library module contains an extensive 
database of healthcare information, consisting primarily of licensed content. 
Healthcare information currently includes pamphlets addressing specific 
diseases and medical issues; a medical encyclopedia; a pharmacy reference; 
information relating to self-help 

                                      23 
<PAGE>

groups; and numerous articles from prominent healthcare periodicals such as 
New England Journal of Medicine and Journal of the American Medical 
Association. Healthcare information is stored in the Company's private 
Website and is accessed through the use of a web browser incorporated into 
the Company's software. 

   Internet Gateway. The Internet gateway module permits access to the World 
Wide Web for additional healthcare information through the use of a web 
browser. Access is limited to websites which the Company believes provide the 
most relevant healthcare information. 

   Feedback. The feedback module allows users to access user surveys and 
technical support forms. 

   Electronic Mail 

   HealthDesk OnLine is designed to permit secure electronic messaging 
between consumers and healthcare payers and providers. Anticipated 
communications between consumers, payers and providers relate to enrollment; 
physician selection; test results and patient information; appointment 
scheduling; reminders; provider directories; surveys; home treatment; and 
explanation of benefits. The Company intends to employ RSA Data Security 
encryption software on both the desktop and database server. 

   HealthDesk OnLine has been designed to operate on IBM compatible desktop 
computers with a minimum requirement of a 80486DX central processing unit and 
eight megabytes of random access memory. The system runs under Windows 95 and 
Windows 3.1. Consumers may access the electronic mail system, the Company's 
private Website and the Internet by dialing a local access number provided by 
CompuServe. The minimum technical requirement to access the electronic 
communications features is a 9600 Baud modem. 

PRODUCT DEVELOPMENT 

   The Company's principal efforts to date have been devoted to the design 
and development of HealthDesk OnLine. For the fiscal years ended December 31, 
1994 and 1995 and the nine months ended September 30, 1996, the Company 
expended approximately $231,000, $681,000 and $1,194,000, respectively, on 
product development. Product development expenses are expected to increase 
through 1997 in connection with market testing activities. As of the date of 
this Prospectus, eleven of the Company's twenty-four employees were engaged 
in product development. 

   Although the Company believes that its development efforts relating to the 
technological aspects of the basic HealthDesk OnLine platform are 
substantially completed, the Company is continually seeking to refine and 
enhance the capabilities of its products. The Company intends to use a 
portion of the proceeds of this offering in connection with refining, 
enhancing and developing system capabilities and features, including the 
following: 

   Electronic Newsletter. The Company has recently incorporated into its 
software an electronic newsletter function which includes a search engine 
technology obtained from Verity, Inc. pursuant to a three year non-exclusive 
license. Such technology is designed to automatically search content 
databases and websites by topic of interest on a periodic basis. The Company 
intends to use this capability to create reports in the form of personalized 
newsletters which may be updated on a regular basis by the Company. The 
Company believes that such newsletter also presents a significant opportunity 
for advertising and promotional "tie-ins" with corporate sponsors. 

   "Chat" Capabilities. The Company will seek to develop and incorporate 
online "chat" capabilities and sponsored healthcare forums into HealthDesk 
OnLine. The Company anticipates that these features will provide consumers 
with an opportunity to discuss healthcare issues with other consumers and 
healthcare experts. 

   Health Risk Assessment. The Company will seek to incorporate into its 
software, content and algorithms designed to assist in health risk assessment 
by providing feedback with respect to the likelihood of risk of certain 
diseases based on health information input by the user. The Company is 
seeking to enter into a third-party license agreement in connection with such 
enhancement. 

   Symptom Triage. The Company has recently incorporated into its products 
software obtained from Healthwise, Inc. pursuant to a non-exclusive license. 
Such software is designed to provide specific responses for treatment based 
on information relating to symptoms input by the user. 

                                      24 
<PAGE>

   Medical Device Integration. The Company may also seek to develop features 
which will facilitate the input of data from medical devices, such as blood 
pressure cuffs, blood glucose monitors and peak flow meters, directly into 
HealthDesk OnLine which data may be monitored by healthcare providers. Any 
such feature may require the Company and/or the medical device manufacturer 
to obtain pre-marketing regulatory approvals. See "Government Regulation." 

   Call Center. In the future, the Company may evaluate the feasibility of 
offering call center services which would allow consumers to speak with a 
nurse or other medical practitioner by phone. The Company believes that a 
call center capability would enhance patient compliance with disease 
management programs. In the event that the Company seeks to develop such 
capability, it will become subject to increased government regulation. See 
"Government Regulation." 

   In addition, the Company intends to develop specific disease management 
modules designed to monitor chronic conditions. The Company believes that 
disease management modules may increase compliance with treatment programs 
designed to address the lifestyle of chronically-ill patients. In August 
1996, the Company and MIIX entered into a letter of intent, as amended, which 
contemplates that the Company will design, develop and test a software module 
for diabetes patients. The letter of intent provides for MIIX to fund up to 
$500,000 of the cost of developing such module, subject to mutually agreed 
milestones, including target dates and acceptance criteria. The letter of 
intent also contemplates that the Company would grant to MIIX a right of 
first refusal to fund the development of other modules. There can be no 
assurance that the Company will be able to enter into a definitive agreement 
with MIIX or otherwise successfully develop or commercialize such software 
module. See "Potential Markets and Marketing." 

   The markets for the Company's products are characterized by rapidly 
changing technology and evolving industry standards, often resulting in 
product obsolescence or short product life cycles. Accordingly, the ability 
of the Company to compete will be dependent on the Company's ability to 
complete development and introduce HealthDesk OnLine into the marketplace in 
a timely manner, to continually enhance and improve its software and to 
successfully develop and market new products. There can be no assurance that 
competitors will not develop technologies or products that render the 
Company's products obsolete or less marketable or that the Company will be 
able to successfully enhance its products or develop new products. 

MARKET TESTING 

   In July 1996, the Company commenced preliminary market testing of 
HealthDesk OnLine pursuant to a license agreement with BCMA. The Company 
agreed to grant to BCMA a limited, non-exclusive, non-transferable license 
to use the HealthDesk trademark and to distribute HealthDesk OnLine to its 
members, subscribers and insureds. The Company also agreed that until the end 
of 1997 it will not grant a license to any health maintenance organization 
which includes rights to distribute HealthDesk OnLine to members in 
Massachusetts. 

   
   The Company has modified HealthDesk OnLine to satisfy BCMA's requirements 
and BCMA is currently testing such product. In the event of successful 
initial acceptance testing, the proposed market test contemplates that BCMA 
will distribute HealthDesk OnLine to up to 50 of its employees during a 
period of ninety days commencing November 1, 1996 and thereafter BCMA will 
have an additional thirty days to determine whether to distribute HealthDesk 
OnLine to up to 500 of its members. The Company currently anticipates that 
BCMA will commence distributing HealthDesk OnLine to its employees in January 
1997. The market test is intended to provide information on the product's 
usability and acceptance by consumers and to test the technical aspects of 
the Company's software. The Company also recently entered into a license 
agreement with BCI to conduct similar market testing to up to 150 of BCI 
employee households. BCI has commenced distributing HealthDesk OnLine to its 
employees. There can be no assurance that such market testing will be 
conducted on a timely basis or that such testing will be successful. 
    

   The agreements with BCMA and BCI require each to pay development fees in 
the event they require modifications to HealthDesk OnLine. The agreements 
also provide for the payment of member maintenance fees; installation fees; 
transaction fees; and online service fees. The Company has waived payment of 
a master license fee in connection with each agreement. The Company's 
agreement with BCMA terminates on April 1, 1997, unless otherwise extended, 
provided that for a period of six months following termination the Company 
may not grant a license to any health maintenance organization which includes 
rights to distribute HealthDesk OnLine to members in Massachusetts. The 
Company's agreement with BCI terminates in February 1997.

   The Company currently proposes to conduct market testing of HealthDesk 
OnLine with BCMA and BCI and other potential sponsoring organizations. The 
Company's success may be highly dependent upon the results of market testing 
and there can be no assurance that such tests will be successful. If such 
tests are not successful, the Company will be required to attempt to enhance 
or modify HealthDesk OnLine so that it will meet with sponsoring organization 
and consumer acceptance. There can be no assurance that the Company will be 
able to modify HealthDesk OnLine so that positive test results can be 
demonstrated. Even if test results are positive, there can be no assurance 
that sponsoring organizations will be sufficiently encouraged by the results 
to commit to use HealthDesk OnLine on a non-market test basis. They may elect 
to utilize other products, services or technologies which they believe to be 
more efficient or have other cost advantages over the Company's system. In 
addition, there can be no assurance that positive test results will translate 
into consumer acceptance over a longer period of time or that sponsoring 
organizations or consumers will be satisfied with operational results. In 
1994, Kaiser and Quantum conducted limited consumer acceptance testing 
activities with respect to the Company's initial product and a specific 
disease software module. While the Company believes that the results of such 
testing were positive, the Company does not have any further arrangements 
with either Kaiser or Quantum to test such products. 

POTENTIAL MARKETS AND MARKETING 

   The Company initially intends to offer HealthDesk OnLine with no license 
fee to potential sponsoring organizations willing to participate in market 
testing in order to closely monitor performance and provide support for the 
users of such product. Such activities are expected to allow the Company to 
adapt and revise its proposed products in light of market needs and user 
feedback, to develop pricing strategies relative to cost structure, to test 
new products and features and to correct software or product defects which 
may arise. Thereafter, although the Company will seek to develop and 
commercialize specific disease management modules, the Company's primary 
marketing strategy is to license HealthDesk OnLine to sponsoring 
organizations (including pharmaceutical companies, managed care 
organizations, disease management companies, employers and affinity groups) 
with access to significant numbers of potential subscribers. The Company 
believes that the addition of HealthDesk OnLine to the products and services 
of sponsoring organizations could enhance the competitive position of such 
organizations by differentiating such organizations' products and services 
from those of competitors. 

   The Company intends to focus its efforts on healthcare organizations 
primarily responsible for bearing the financial risk of patients with chronic 
diseases. The Company's letter of intent with MIIX contemplates that the 
Company would pay royalties to MIIX ranging from 3% to 10% of revenues 
derived from the sale or license of a software module designed for diabetes 
patients. There can be no assurance that the Company will be able to enter 
into a definitive marketing agreement or that any marketing efforts 
undertaken by MIIX will be successful. 

   The Company is currently evaluating various other commercialization 
strategies, including the license of HealthDesk OnLine to manufacturers of 
medical devices, pursuant to arrangements by which such manufacturers would 
bundle such product with the products of such manufacturers. The Company does 
not have any specific plans or arrangements with respect to such products and 
any such arrangements could require the Company and/or a medical device 
manufacturer to obtain pre-marketing regulatory approvals. See "Government 
Regulation." 

   The Company may also seek to establish strategic relationships with third 
parties relating to product development and marketing. In May 1996, the 
Company entered into cross-license agreements with Patient Infosystems Inc. 
("PII"), formerly known as Disease State Management, Inc., a company engaged 
in providing healthcare information systems designed to improve patient 
compliance. Pursuant to such agreements, the Company granted to PII a 
non-exclusive right to market HealthDesk OnLine and PII granted to the 
Company a non- exclusive right to market PII's advanced voice recognition 
telephone system capabilities. The Company believes that such arrangement 
will permit the Company to offer its services to patients who do not have 
access to personal computers. 

   Under the agreements, each party agreed to seek cost estimates (which 
would be based on direct costs incurred) in developing modifications 
necessary to deliver specific services requested by potential customers. 
Operational fees would be based on certain assumptions contained in the 
agreements (subject to the parties' standard terms and conditions). The 
agreements have an initial term of six months and are automatically renew- 

                                      26 
<PAGE>

able for successive terms unless either party gives 30 days' written notice 
prior to the termination of any renewal term. The agreements provide for each 
party to pay an initial license fee of $25,000 and $25,000 for each renewal 
term. John Pappajohn, a director and principal shareholder of the Company, is 
a principal shareholder and director of PII. Edgewater, a principal 
shareholder of the Company, is also a principal shareholder of PII. PII may 
be a competitor of the Company. See "Certain Transactions." 

   The Company's prospects will be substantially affected by its ability to 
successfully develop and maintain relationships with key sponsoring 
organizations, which will promote their services using HealthDesk OnLine and, 
at the same time attract significant numbers of subscribers. The Company's 
revenues from third-party marketing arrangements are generally expected to be 
lower than if the Company sold its products directly to end-users, although 
the Company would not incur the expense of creating a distribution network 
and would anticipate a greater volume of end-user sales. To the extent that 
the Company is ultimately able to enter into satisfactory third-party 
marketing arrangements, the Company will be largely dependent on the efforts 
of such third parties. In the case of any such arrangements, the Company's 
products will require adaptation for specific customers, which could delay 
product commercialization. In addition, the Company will be dependent on the 
marketing efforts of third parties and on the marketability and sales of 
their products. There can be no assurance that the Company will be able to 
enter into third-party marketing arrangements, that it will be able to adapt 
its products for specific customers on a timely basis, or at all, or that the 
Company will realize substantial revenues from any such arrangements. 

   The Company's executive officers and marketing staff of three persons are 
currently responsible for substantially all of the Company's marketing 
efforts. Because of the nature of the Company's business, the Company's 
executive officers are expected to continue to devote significant time to 
develop personal relationships with senior contacts at sponsoring 
organizations. The Company's ability to market HealthDesk OnLine may be 
limited by the number of marketing personnel and will be largely dependent 
upon the efforts of such individuals. HealthDesk, the Company's initial 
product, is currently marketed directly to consumers pursuant to agreements 
with two independent sales representatives. The Company does not expect 
future revenues derived from such product to be meaningful. 

   The Company's marketing strategy and preliminary and future marketing 
plans may be unsuccessful and are subject to change as a result of a number 
of factors, including progress or delays in the Company's marketing efforts, 
changes in market conditions (including the emergence of potentially 
significant related market segments for applications of the Company's 
technology), the nature of possible license and distribution arrangements 
which may become available to it in the future and economic, political, 
regulatory and competitive factors. There can be no assurance that the 
Company's strategy will result in successful product commercialization. 

COMPETITION 

   The markets that the Company intends to enter are characterized by intense 
competition and an increasing number of new market entrants who have 
developed or are developing competitive products. The Company will face 
competition from numerous sources, including prospective customers which may 
develop and market their own competitive products and services, health 
information system vendors, software companies and online and Internet 
service providers. The Company believes that competition will be based 
primarily on ease of use, features (including communications capabilities and 
content) and price. The Company believes that the combination of desktop and 
online functionality of HealthDesk OnLine may provide the Company with a 
competitive advantage. 

   In addition, certain companies have developed or may be expected to 
develop technologies or products in related market segments which could 
compete with certain technologies or products being developed by the Company. 
The Company expects that companies which have developed or are developing 
such technologies or products, as well as other companies (including 
established and newly formed companies) may attempt to develop products 
directly competitive with HealthDesk OnLine. In particular, several 
companies, including Healtheon, IBM Global Health Village, MedAccess 
Corporation, CareSoft, Inc., Access Health, Inc. and America's Housecalls 
Network, have announced plans to develop and commercialize competitive 
product and service offerings. Among other things, these products and 
services include the use of the Internet for electronic communication between 
health plans and consumers regarding plan matters, World Wide Web sites with 
information 

                                      27 
<PAGE>

regarding healthcare related matters and other Internet based products which 
are to offer health related information. Certain of such competitors have 
substantially greater financial, technical, marketing, distribution personnel 
and other resources than the Company, permitting such companies to implement 
extensive marketing campaigns, both generally and in response to efforts by 
additional competitors to enter into new markets and market new products and 
services. 

   Healtheon has announced that it has entered into an agreement with BCMA 
relating primarily to the electronic exchange of health plan benefit 
information between consumers and health plans. There can be no assurance 
that Healtheon's relationship with BCMA will not adversely affect the 
Company's ability to successfully market HealthDesk OnLine to BCMA or that 
the Company will be able to compete successfully. 

INFRASTRUCTURE, OPERATIONS AND TECHNOLOGY 

   The Company intends to make HealthDesk OnLine available to users through a 
set of network servers housed in Berkeley, California. The Company 
anticipates that access to the Internet will be provided on a 24 hour a day, 
seven days a week basis through various communications line providers. 

   The Company's operations will depend upon the capacity, reliability and 
security of its system infrastructure. The Company currently has limited 
system capacity and will be required to continually expand its system 
infrastructure to accommodate significant numbers of users and increasing 
amounts of information they may wish to access. Expansion of the Company's 
system infrastructure will require substantial financial, operational and 
management resources. The Company intends to use a portion of the proceeds of 
this offering to purchase computer equipment to expand system capacity. There 
can be no assurance that the Company will be able to expand its system 
infrastructure to meet potential demand on a timely basis, at a commercially 
reasonable cost, or at all. Failure by the Company to expand its network 
infrastructure on a timely basis could have a material adverse effect on the 
Company. In addition, the Company will be dependent upon Web browsers and 
third-party Internet and online service providers for access to the Company's 
services, hardware suppliers for prompt delivery, installation and service of 
computer equipment used to deliver the Company's services and on content 
providers to provide current healthcare information for use by consumers. 

   The Company has entered into an Online Vendor License Agreement with 
Information Access Company ("IAC") for online access to an electronic 
database of proprietary content. The IAC database is currently the principal 
source of content available on the Company's private Website and includes a 
wide range of consumer-oriented health publications, medical journals, 
articles, pamphlets and reference books. The non-exclusive, worldwide, 
royalty-bearing license requires the Company to include IAC's standard terms 
and conditions in the Company's standard subscriber terms and conditions, and 
display certain IAC legends and copyright notices. Either party may terminate 
the agreement with ninety days' notice after completion of a nine-month beta 
test period, which expires in May 1997. Thereafter, the agreement continues 
for a three-year period and may be terminated by either party at the end of 
each year with ninety days' notice. 

   The Company has entered into a Content License Agreement with Healthwise, 
Inc. ("Healthwise"), a publisher of self care health information for 
consumers. The agreement provides a non-exclusive, worldwide, license to the 
Company for the use of certain content published by Healthwise, including the 
Healthwise Handbook and Pathways. The agreement continues indefinitely and is 
terminable for cause upon two weeks' notice and without cause upon six 
months' notice. In addition, the Company has entered into a Software License 
Agreement with Healthwise for the use of Healthwise's Knowledgebase Symptom 
Manager and Health and Disease Manager software in the Company's products. 
Such software is designed to allow the Company's customers to triage their 
symptoms and locate information on specific disease states. The agreement 
provides for a non-exclusive, worldwide, royalty-bearing license. The 
agreement has renewable one-year terms, unless terminated by either party 
upon ninety-days' notice prior to expiration of the then current term. 

   The Company has entered into a Subscription License Agreement with Verity, 
Inc. ("Verity") for the use in the Company's on-line products of certain 
information indexing and retrieval software. The search engine feature is 
used to locate content on the IAC database through the Company's development 
of search queries. The agreement provides for a non-exclusive, worldwide, 
royalty-bearing license. The agreement expires in May 1997. 

   The Company has entered into a license agreement with Netscape, Inc. to 
license Netscape's browser technology for integration into the Company's 
product. The license is a royalty bearing non-exclusive license for an 
initial one year period expiring in September 1997. 

                                      28 
<PAGE>

   The Company has entered into an OEM Master License Agreement with RSA Data 
Security, Inc. ("RSA") for the use of certain encryption software to secure 
the Company's messaging system. The Company intends to use the RSA encryption 
software on both the desktop as well as the Company's private website to 
ensure that all communications are secure. Through the use of a public key 
system of encryption, the Company is able to encode patient communications, 
which may only be decrypted by the designated receiver. The agreement 
provides for a non-exclusive, royalty-bearing license. 

   The Company believes that if any of such licenses are terminated, that 
there are multiple other sources from which the Company will be able to 
license appropriate content or similar technology. 

POTENTIAL LIABILITY AND INSURANCE 

   In recent years, participants in the healthcare industry have been subject 
to an increasing number of lawsuits alleging malpractice, product liability 
and related legal theories, many of which involve large claims and 
significant defense costs. Due to the nature of its business, the Company 
could become involved in litigation regarding the healthcare information 
transmitted over its system with the risk of adverse publicity, significant 
defense costs and substantial damage awards. The Company has adopted policies 
and procedures intended to reduce the risk of claims, which include the 
provision of disclaimers in connection with its services. The Company does 
not maintain malpractice liability insurance. 

   In addition, because healthcare information and materials may be 
downloaded and may be subsequently distributed to others, there is a 
potential that claims will be made against the Company for defamation, 
negligence, copyright or trademark infringement or other theories based on 
the nature and content of such materials. The Company also could be exposed 
to liability in connection with the selection of materials that may be 
accessible over its system. Claims could be made against the Company if 
material deemed inappropriate for viewing by children could be accessed. The 
Company carries an umbrella insurance policy with a limit of $4 million in 
the aggregate, general liability insurance with a limitation of $2 million in 
aggregate and $1 million per occurrence and errors and omissions insurance 
with a limitation of $1 million in the aggregate. Nevertheless, the Company's 
insurance may not cover potential claims of this type or may not be adequate 
to cover liability that may be imposed or related defense costs. There can be 
no assurance that the Company will not face claims resulting in substantial 
liability for which the Company is partially or completely uninsured. Any 
partially or completely uninsured claim against the Company, if successful 
and of sufficient magnitude, would have a material adverse effect on the 
Company. 

GOVERNMENT REGULATION 

   The healthcare industry is subject to extensive, stringent and frequently 
changing federal and state regulation which is interpreted and enforced by 
regulatory authorities with broad discretion. Among other things, these 
regulations govern the provision of healthcare services and the marketing of 
medical devices. These regulations generally predate the development of 
products and services such as those offered by the Company and the 
application and enforcement of such regulations to the Company and its 
products and services is uncertain. However, certain of the statutes 
governing the provision of healthcare services could be construed by 
regulatory authorities to apply to the Company's proposed business 
activities. There can be no assurance that regulatory authorities do not or 
will not deem the Company's business activities to constitute the unlicensed 
practice of medicine. 

   Furthermore, in the event the Company develops features which facilitate 
the input of data from medical devices directly into HealthDesk OnLine, it is 
possible that the Federal Food and Drug Administration could require the 
Company and/or an equipment manufacturer to obtain pre-marketing clearance 
with respect to any such product. The process of obtaining and maintaining 
required regulatory approval can be lengthy, expensive and uncertain. Even if 
regulatory approvals are obtained, a marketed product and its manufacturer 
are subject to continuing regulatory review, and discovery of previously 
unknown problems could result in restrictions on such product or 
manufacturer, including withdrawal of the product from the market. Amendments 
to or interpretation and enforcement of existing statutes or regulations, the 
adoption of new statutes or regulations or the development of new 
enhancements and features to HealthDesk OnLine could subject the Company to 
increased regulation and require the Company to alter methods of operation at 
costs which could be substantial. Failure to comply with applicable laws and 
regulations could subject the Company to civil remedies, including 
substantial fines, penalties and injunctions, as well as possible criminal 
sanctions. 

                                      29 
<PAGE>

   Although there are currently few laws or regulations directly applicable 
to access to or commerce on the Internet, due to the increasing popularity 
and use of the Internet, it is possible that laws and regulations may be 
adopted with respect to the Internet, covering issues such as user privacy, 
pricing and characteristics and quality of products and services. The 
Telecommunications Reform Act of 1996, which was recently enacted, imposes 
criminal penalties on anyone who distributes obscene, lascivious or indecent 
communications on the Internet. Although the enforcement of such statute has 
been enjoined and is currently subject to challenge in the courts, the 
adoption of any such laws or regulations may limit the growth of the 
Internet, which could in turn decrease the demand for the Company's products 
and services and increase the Company's cost of doing business. Inasmuch as 
the applicability to the Internet of the existing laws governing issues such 
as property ownership, libel and personal privacy is uncertain, any such new 
legislation or regulation or the application of existing laws and regulations 
to the Internet could have an adverse effect on the Company's proposed 
business and prospects. 

PROPRIETARY INFORMATION AND TRADEMARKS 

   The Company does not hold any patents or registered copyrights. The 
Company regards certain computer software it has developed for HealthDesk 
OnLine as proprietary and attempts to protect it with copyrights, trade 
secret laws, proprietary rights agreements and internal nondisclosure 
agreements and safeguards. However, such methods may not afford complete 
protection and there can be no assurance that others will not independently 
develop know-how or obtain access to the Company's know-how or software 
codes, concepts, ideas and documentation. Furthermore, there can be no 
assurance that nondisclosure agreements with the Company's employees will 
adequately protect the Company's trade secrets. Although the Company believes 
that its proposed products do not and will not infringe patents or violate 
proprietary rights of others, it is possible that infringement of existing or 
future patents or proprietary rights of others have occurred or may occur. In 
the event the Company's proposed products infringe patents or proprietary 
rights of others, the Company may be required to modify the design of its 
proposed products or obtain a license. There can be no assurance that the 
Company will be able to do so in a timely manner, upon acceptable terms and 
conditions or at all. The failure to do any of the foregoing could have a 
material adverse effect upon the Company. In addition, there can be no 
assurance that the Company will have the financial or other resources 
necessary to enforce or defend a patent infringement action and the Company 
could, under certain circumstances, become liable for damages, which also 
could have a material adverse effect on the Company. 

   The Company currently holds a United States trademark registration for the 
"HealthDesk" name and related logo. The Company is not aware of any claims or 
infringement or other challenges to the Company's rights to use this mark. 

EMPLOYEES 

   As of November 30, 1996, the Company had 24 full time employees, of which 
four were executive officers, eleven were engaged in product development, 
three were engaged in marketing and six were engaged in administrative 
activities. The Company's employees are not represented by a collective 
bargaining unit. The Company believes that its relations with its employees 
are good. 

FACILITIES 

   The Company's facilities are located in 5,701 square feet of leased office 
space in Berkeley, California. The lease expires in January 1999 and provides 
for an annual rental of $108,564. 

   The Company's operations will be dependent on the Company's ability to 
protect its computer equipment against damage from fire, earthquakes, power 
loss, telecommunications failures and similar events. The Company does not 
presently have redundant, multiple site capacity in the event of any such 
occurrence. Notwithstanding the implementation of system security measures by 
the Company, its servers will also be vulnerable to computer viruses, 
break-ins and similar disruptions from unauthorized tampering with the 
Company's computer systems. Computer viruses or problems caused by third 
parties could lead to material interruptions, delays or cessation in service 
to consumers. 

LEGAL PROCEEDINGS 

   The Company is subject to two complaints filed by former employees with 
the California Department of Fair Employment & Housing. One claim alleges 
wrongful termination as a result of alleged denial of reasonable 

                                      30 
<PAGE>

accommodation for a wrist and neck injury. The second complaint alleges that 
the former employee was subject to sexual harassment by a former officer of 
the Company. The Company intends to defend these matters vigorously. There 
can be no assurance, however, that such matters will be resolved in a manner 
favorable to the Company.

of $163,200, $140,000 and $110,000, respectively, and bonuses to be

is entitled to receive a bonus of $80,000 in February 1997. The agreements 
also provide for employment on a full-time basis and contain a provision that 
the employee will not compete or engage in a business competitive with the 
Company for a period of one year after termination. In the event of 
termination of the employee's employment by the Company other than for cause

applicable annual base salary plus a pro rata portion of the bonus payable

1994 STOCK OPTION PLAN 

   The Company's 1994 Founder's Stock Option Plan (the "Option Plan") became 
effective in June 1994 and was amended most recently in March 1996. The 
purpose of the Option Plan is to attract and retain qualified personnel, to 
provide additional incentives to employees, officers and consultants of the 
Company and to promote the success of the Company's business. A reserve of 
950,000 shares of the Company's Common Stock has been established for 
issuance under the Option Plan. The Option Plan is administered by the 
Compensation Committee of the Board of Directors (the "Committee"). Subject 
to the Option Plan, the Committee has complete discretion to determine which 
eligible individuals are to receive option grants, the number of shares 
subject to each such grant, the status of any granted option as either an 
incentive stock option or a non-statutory option, the vesting schedule to be 
in effect for the option grant and the maximum term for which any granted 
option is to remain outstanding. 

   Each option granted under the Option Plan has a maximum term of ten years, 
subject to earlier termination following the optionee's cessation of service 
with the Company. Options are generally immediately exercisable subject to a 
right of repurchase in favor of the Company at the original exercise price 
which expires over a four-year vesting period. The exercise price of 
incentive stock options and non-statutory stock options granted under the 
Option Plan must be at least 100% and 85% of the fair market value of the 
stock subject to the option on the date of grant, respectively or 110% with 
respect to holders of more than 10% of the voting power of the Company's 
outstanding stock. The Committee determines the fair market value of the 
stock. The purchase price is payable immediately upon the exercise of the 
option. Such payment may be made in cash, or at the discretion of the 
Committee, in outstanding shares of Common Stock held by the participant, 
through a full recourse promissory note payable in installments over a period 
of years or any combination of the foregoing. 

   The Board of Directors may amend or modify the Option Plan at any time, 
provided that no such amendment or modification may adversely affect the 
rights and obligations of the participants with respect to their outstanding 
options or unvested shares without their consent. In addition, no amendment 
of the Option Plan may, without the approval of the Company's shareholders, 
(i) materially modify the class of individuals eligible for participation, 
(ii) increase the number of shares available for issuance, except in the 
event of certain changes to the Company's capital structure, (iii) materially 
increase the benefits accruing to Optionees under the Option Plan, or (iv) 
extend the term of the Option Plan. The Option Plan will terminate in June 
2004, unless terminated earlier by the Board. 

   As of the date of this Prospectus, there are options to purchase an 
aggregate of 768,050 shares outstanding under the Plan with an average 
exercise price of $2.95. Peter O'Donnell holds 180,000 outstanding options, 
135,324 of which were granted at an exercise price of $1.04 per share and 
44,676 of which were granted at an exercise price of $2.08 per share. Joseph 
Rudick holds 24,000 options, 12,000 of which were granted at an exercise 
price of $1.04 per share, and 12,000 of which were granted at an exercise 
price of $1.67 per share. Molly Coye holds 132,000 outstanding options, 
96,000 of which were granted at an exercise price of $3.33 per share and 
36,000 of which were granted at $5.00 per share. Timothy Yamauchi holds 
60,000 outstanding options, 45,210 of which were granted at an exercise price 
of $1.04 per share, and 14,790 of which were granted at an exercise price of 
$2.08 per share. Gerald Zieg holds 50,000 outstanding options which were 
granted at an exercise price of $5.00 per share. 

                                      34 
<PAGE>

   All options are immediately exercisable subject to repurchase rights in 
favor of the Company based upon the following vesting schedule: the optionee 
shall acquire a vested interest in, and the Company's repurchase rights will 
accordingly lapse with respect to, (i) twenty-five percent (25%) of the 
option shares upon completion of one year of service (as a director or 
employee, as the case may be) measured from the respective vesting 
commencement date, and (ii) the balance of the option shares in equal 
successive monthly installments upon completion of each of the next 
thirty-six (36) months of service measured from and after the first 
anniversary of such vesting commencement date. 

OTHER BENEFIT PLANS 

   The Company maintains a 401(k) savings plan and a Section 125 medical and 
dental savings plan. 

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS 

   The Company's Articles of Incorporation (the "Articles") limit the 
liability of directors to the maximum extent permitted by California law. The 
Articles authorize the Company to indemnify agents of the Company in excess 
of the indemnification otherwise permitted by Section 317 of the California 
General Corporation Law, subject only to applicable limits set forth in 
Section 204 of the California General Corporation Law with respect to actions 
for breach of duty to the corporation and its shareholders. 

   The Company's Bylaws provide that the Company shall indemnify its 
directors, officers, employees and other agents to the fullest extent 
permitted by law. The Company believes that indemnification under its Bylaws 
covers at least negligence and gross negligence on the part of indemnified 
parties. The Company's Bylaws also permit it to secure insurance on behalf of 
any officer, director, employee or other agent for any liability arising out 
of his or her actions in such capacity, regardless of whether the Bylaws 
would permit indemnification. 

   The Company has entered into agreements to indemnify its directors and 
executive officers. These agreements, among other things, indemnify the 
Company's directors and executive officers for certain expenses (including 
attorneys' fees), judgments, fines and settlement amounts incurred by any 
such person in any action or proceeding, including any action by or in the 
right of the Company, arising out of such person's services as a director or 
executive officer of the Company or any other company or enterprise to which 
the person provides services at the request of the Company. The Company 
believes that these provisions and agreements are necessary to attract and 
retain qualified persons as directors and executive officers. 

   At present, there is no pending litigation or proceeding involving any 
director, officer, employee or agent of the Company where indemnification 
will be required or permitted. The Company is not aware of any threatened 
litigation or proceeding that might result in a claim for such 
indemnification.

                             CERTAIN TRANSACTIONS 

   In May 1993, the Company issued 120,000 shares of Common Stock to John 
Pappajohn, a director and principal shareholder of the Company, for an 
aggregate consideration of $125,000. In May 1994, the Company issued 30,000 
shares of Common Stock to Mr. Pappajohn for an aggregate consideration of 
$31,250 (or $1.04 per share). The Company has granted registration rights to 
Mr. Pappajohn with respect to all of such shares. 

   In August 1995, Mr. Pappajohn and Edgewater Private Equity Fund II, L.P. 
("Edgewater") purchased an aggregate of 636,000 shares of Common Stock from 
David Hehman, the former Chief Executive Officer of the 

                                      36 
<PAGE>

Company, and certain of his family members, for an aggregate consideration of 
$662,500. James Gordon, a director of the Company, is president of the 
General Partner of Edgewater. In connection with such transaction, Mr. Hehman 
and such family members entered into a severance agreement with the Company 
which provided for their respective resignations as officers, directors and 
employees of the Company, their agreement not to compete for one year with 
the Company and the termination of options to purchase an aggregate of 
198,000 shares of Common Stock. Pursuant to such severance agreement, the 
Company paid such individuals an aggregate of $50,000. In addition, in 
consideration of $5,000, Spartina Corporation, a company controlled by Mr. 
Hehman, assigned to the Company all of its right, title and interest in and 
to certain software development tools previously licensed by the Company from 
Spartina Corporation pursuant to a non-exclusive license agreement entered 
into in April 1993. In connection with such transaction, Mr. Pappajohn and 
Edgewater were granted registration rights with respect to all of such 
shares. 

   In August 1995, the Company granted to Mr. Pappajohn options to purchase 
96,000 shares of Common Stock at an exercise price of $1.04 per share. Such 
options were exercised in December 1995. In September 1996, the Company 
granted Mr. Pappajohn and Mr. Sengpiel, a director of the Company, options to 
purchase 10,000 and 15,000 shares of Common Stock, respectively, at an 
exercise price of $5.00 per share. 

   During the period from June through September 1995, the Company borrowed 
an aggregate of $800,000 from Mr. Pappajohn and Edgewater, evidenced by 
convertible promissory notes bearing interest at the rate of 6% per annum. 
The principal of the notes were converted into an aggregate of 768,000 shares 
of Common Stock in September 1995. 

   In December 1995, Mr. Pappajohn and Edgewater, purchased 69,000 and 
129,000 shares of the Company's Series A Preferred Stock for an aggregate 
purchase price of approximately $144,000 and $268,000, respectively. 

   In May 1996, the Company and PII entered into cross-license agreements in 
connection with possible product development and marketing arrangements. 
Pursuant to such agreements, each party paid the other an initial license fee 
of $25,000. Similar fees are payable upon any renewal of such agreements. Mr. 
Pappajohn is a principal shareholder and a director of PII. Edgewater is also 
a principal shareholder of PII. 

   In July and August 1996, the Company borrowed an aggregate of $500,000 
from Mr. Pappajohn and Edgewater. Such indebtedness bears interest at the 
rate of 8% per annum. The principal of such notes will automatically convert 
into approximately 100,000 shares of Common Stock on the date of this 
Prospectus. 

   Mr. Pappajohn and Edgewater each purchased $100,000 of Units consisting of 
20,000 shares of Common Stock at an attributed price of $2.25 per share and a 
9% non-negotiable promissory note in the principal amount of $100,000 in 
connection with the Bridge Financing. 

   The Company believes that all of the foregoing transactions and 
arrangements were fair and reasonable to the Company and were on terms no 
less favorable than could have been obtained from unaffiliated third parties. 
There can be no assurance, however, that future transactions or arrangements 
between the Company and its affiliates will continue to be advantageous to 
the Company, that conflicts of interest will not arise with respect thereto, 
or that if conflicts do arise, they will be resolved in a manner favorable to 
the Company. Any such future transactions will be on terms no less favorable 
to the Company than could be obtained from unaffiliated parties and will be 
approved by a majority of the independent and disinterested members of the 
Board of Directors, outside the presence of any interested directors and, to 
the extent deemed appropriate by the Board of Directors, the Company will 
obtain shareholder approval or fairness opinions in connection with any such 
transaction.

                          DESCRIPTION OF SECURITIES 

   Upon completion of this offering, the authorized capital stock of the 
Company will consist of 17,000,000 shares of Common Stock, 5,489,720 of which 
will be outstanding, and 3,000,000 shares of Preferred Stock, none of which 
will be outstanding. The following description of the capital stock of the 
Company and certain provisions of the Company's Restated Articles of 
Incorporation and Bylaws is a summary and is qualified in its entirety by the 
provisions of the Restated Articles of Incorporation and Bylaws, copies of 
which have been filed as exhibits to the Registration Statement of which this 
Prospectus is a part. 
    

Common Stock 

   The holders of Common Stock are entitled to one vote per share on all 
matters submitted to a vote of the shareholders, including the election of 
directors, and, subject to preferences that may be applicable to any 
Preferred Stock outstanding at the time, are entitled to receive ratably such 
dividends, if any, as may be declared from time to time by the Board of 
Directors out of funds legally available therefor. See "Dividend Policy." In 
the event of liquidation or dissolution of the Company, the holders of Common 
Stock are entitled to receive all assets available for distribution to the 
shareholders, subject to any preferential rights of any preferred stock then 
outstanding. The holders of Common Stock have no preemptive or other 
subscription rights, and there are no conversion rights or redemption or 
sinking fund provisions with respect to the Common Stock. All outstanding 
shares of Common Stock are, and the shares offered hereby upon issuance and 
sale will be, fully paid and nonassessable. The rights, preferences and 
privileges of the holders of Common Stock are subject to, and may be 
adversely affected by, the rights of the holders of any shares of preferred 
stock which the Company may designate and issue in the future. 

   The Company's shareholders currently may cumulate their votes for the 
election of directors so long as at least one shareholder has given notice at 
the meeting of shareholders prior to the voting of that shareholder's desire 
to cumulate his or her votes. Cumulative voting may be eliminated by 
amendment to the Articles or the Company's Bylaws if (i) the Company's shares 
of Common Stock are listed on the Nasdaq National Market and the Company has 
at least 800 holders of its equity securities as of the record date of the 
Company's most recent annual meeting of shareholders or (ii) the Company's 
shares of Common Stock are listed on the New York Stock Exchange or the 
American Stock Exchange. 

Preferred Stock 

   The Company is authorized to issue 3,000,000 shares of preferred stock. Of 
such shares, 1,200,000 represent Series A Preferred Stock of which the 
1,059,600 outstanding shares will automatically convert upon the consummation 
of this offering. The remaining 1,800,000 shares may be issued from time to 
time in one or more series upon authorization by the Company's Board of 
Directors. The Board of Directors, without further approval of the 
shareholders, is authorized to fix the dividend rights and terms, conversion 
rights, voting rights, redemption rights and terms, liquidation preferences, 
and any other rights, preferences, privileges and restrictions applicable to 
each series of preferred stock. The issuance of preferred stock, while 
providing flexibility in connection with possible acquisitions and other 
corporate purposes could, among other things, adversely affect the voting 
power of the holders of Common Stock and, under certain circumstances, make 
it more difficult for a third party to gain control of the Company, 
discourage bids for the Company's Common Stock at a premium or otherwise 
adversely affect the market price of the Common Stock. The Company has no 
current plans to issue any preferred stock. 

   
REDEEMABLE WARRANTS 

   Each Warrant entitles the registered holder thereof to purchase one share 
of Common Stock, at a price of $5.00, subject to adjustment in certain 
circumstances, at any time after      , 1998 until      , 2002. 

   The Warrants are redeemable by the Company, upon the consent of the 
Underwriter, at any time after      , 1998, upon notice of not less than 30 
days, at a price of $.10 per Warrant, provided that the clos- 

                                      38

ing bid price of the Common Stock on all 30 of the trading days ending on the 
third day prior to the day on which the Company gives notice has been at 
least 150% (currently $7.50, subject to adjustment) of the then effective 
exercise price of the Warrants. All warrantholders have exercise rights until 
the close of business on the date fixed for redemption. 

   The Warrants will be issued in registered form under a Warrant Agreement 
between the Company and American Stock Transfer & Trust Company as Warrant 
Agent. Reference is made to said Warrant Agreement for a complete description 
of the terms and conditions therein (the description herein contained being 
qualified in its entirety by reference thereto). 

   The exercise price and number of shares of Common Stock or other 
securities issuable on exercise of the Warrants are subject to adjustments in 
certain circumstances, including in the event of a stock dividend, 
recapitalization, reorganization, merger or consolidation of the Company. 
However, such Warrants are not subject to adjustment for issuances of Common 
Stock at a price below the exercise price of the Warrants, including the 
issuance of shares of Common Stock pursuant to the Option Plan. 

   The Warrants may be exercised upon surrender of the Warrant certificate on 
or prior to the expiration date at the offices of the Warrant Agent, with the 
exercise form on the reverse side of the certificate completed and executed 
as indicated, accompanied by full payment of the exercise price (by certified 
check payable to the Company) to the Warrant Agent for the number of Warrants 
being exercised. The warrantholders do not have the rights or privileges of 
holders of Common Stock. 

   No Warrant will be exercisable unless at the time of exercise the Company 
has filed a current registration statement with the Commission covering the 
shares of Common Stock issuable upon exercise of such Warrant and such shares 
have been registered or qualified or deemed to be exempt under the securities 
laws of the state of residence of the holder of such Warrant. The Company 
will use its best efforts to have all such shares so registered or qualified 
on or before the exercise date and to maintain a current prospectus relating 
thereto until the expiration of the Warrants, subject to the terms of the 
Warrant Agreement. While it is the Company's intention to do so, there is no 
assurance that it will be able to do so. 

   No fractional shares will be issued upon exercise of the Warrants. 
However, if a warrantholder exercises all Warrants then owned of record by 
him, the Company will pay such warrantholder, in lieu of the issuance of any 
fractional shares which is otherwise issuable, an amount in cash based on the 
market value of the Common Stock on the last trading day prior to the 
exercise date. 
    

Registration Rights 

   
   In connection with this offering, in addition to the registration 
obligations with respect to the shares of Common Stock issuable upon exercise 
of the Warrants, the Company has agreed to grant to the Underwriter certain 
demand and piggyback registration rights in connection with the 360,000 
shares of Common Stock issuable upon exercise of the Underwriter's Warrants 
and the warrants included therein. See "Underwriting." 
    

   Pursuant to the terms of the Bridge Financing, the Company has included 
the shares issued in the Bridge Financing in the Registration Statement of 
which this Prospectus forms a part. The Company has agreed to use its best 
efforts to keep the Registration Statement effective until the earlier of (i) 
the date that all of the shares included in the Registration Statement have 
been sold pursuant thereto and (ii) the date the Selling Shareholders receive 
an opinion of counsel that the full amount of their shares may be freely sold 
by such holders. All registration expenses related to such shares will be 
paid by the Company. If the Company defaults in its obligations to maintain 
the Registration Statement effective or otherwise fails to comply with 
certain other registration rights obligations of the Bridge Financing, the 
Company may be obligated to issue up to an additional 100,000 shares of 
Common Stock to the investors which participated in the Bridge Financing. 

   The shares offered by the Selling Shareholders may not be sold prior to 
twelve months from the date of this Prospectus and, without the prior written 
consent of the Underwriter, may not be sold prior to eighteen months after 
the date of this Prospectus. 

   In addition to the rights described above, the holders ("Holders") of an 
aggregate of approximately 1,341,600 shares of Common Stock are entitled to 
certain rights with respect to the registration of such shares for offer and 
sale to the public under the Securities Act. Under these provisions, the 
Holders may request that 

                                      39 
<PAGE>

the Company file up to one registration statement under the Securities Act 
with respect to at least 50% of such Common Stock. Upon receipt of such a 
request, the Company is required to notify all other Holders and to effect as 
soon as practicable such registration, subject to certain conditions, 
including that the request must be received one year or more after the 
effective date of this offering, and no later than December 31, 2000. 
Further, whenever the Company proposes to register any of its securities 
under the Securities Act for its own account or for the account of other 
security holders, the Company is required to promptly notify each Holder of 
the proposed registration and include all Common Stock which such Holder may 
request to be included in such registration, subject to certain limitations. 
The Company has obtained a waiver of these rights to the extent they would 
have applied to this offering. 

   
Transfer and Warrant Agent 

   The transfer and warrant agent for the Common Stock and Warrants is 
American Stock Transfer and Trust Company, New York, New York. 
    

                       SHARES ELIGIBLE FOR FUTURE SALE 

   
   Upon consummation of this offering, the Company will have 5,489,720 shares 
of Common Stock outstanding (assuming no exercise of the Warrants), of which 
2,200,000 shares, consisting of 1,800,000 shares offered hereby and, subject 
to certain contractual restrictions described below, the 400,000 shares being 
offered by the Selling Shareholders, will be freely tradable without 
restriction or further registration under the Securities Act. All of the 
remaining 3,289,720 shares of Common Stock outstanding are "restricted 
securities," as that term is defined in Rule 144 promulgated under the 
Securities Act, and in the future may be sold only pursuant to an effective 
registration statement under the Securities Act, in compliance with the 
exemption provisions of Rule 144 or pursuant to another exemption under the 
Securities Act. Of the 3,289,720 restricted shares, an aggregate of 237,000 
shares will be eligible for sale, without registration, under Rule 144 
(subject to the contractual restrictions described below), on the date of 
this Prospectus, and 417,000 shares will be eligible (subject to certain 
volume limitations and the contractual restrictions described below) 
commencing 90 days from the date of this Prospectus. 
    

   In general, under Rule 144 as currently in effect, if two years have 
elapsed since the later of the date of the acquisition of restricted shares 
of Common Stock from either the Company or any affiliate of the Company, the 
acquirer or subsequent holder thereof may sell, within any three-month period 
commencing 90 days after the date of this Prospectus, a number of shares that 
does not exceed the greater of 1% of the then outstanding shares of Common 
Stock, or the average weekly trading volume of the Common Stock on the Nasdaq 
SmallCap Market during the four calendar weeks preceding the date on which 
notice of the proposed sale is sent to the Commission. Sales under Rule 144 
are also subject to certain manner of sale provisions, notice requirements 
and the availability of current public information about the Company. If 
three years have elapsed since the later of the date of the acquisition of 
restricted shares of Common Stock from the Company or any affiliate of the 
Company, a person who is not deemed to have been an affiliate of the Company 
at any time for 90 days preceding a sale would be entitled to sell such 
shares under Rule 144 without regard to the volume limitations, manner of 
sale provisions or notice requirements. 

   The Company's officers, directors and security holders (excluding the 
holders of 42,000 shares of Common Stock) have agreed not to sell or dispose 
of any of their securities of the Company for a period of eighteen months 
from the date of this Prospectus without the Underwriter's prior written 
consent. 

   
   Prior to this offering, there has been no market for the Common Stock and 
no prediction can be made as to the effect, if any, that public sales of 
shares of Common Stock or the availability of such shares for sale will have 
on the market prices of the Common Stock and Warrants prevailing from time to 
time. However, the possibility that a substantial amount of Common Stock may 
be sold in the public market may adversely affect prevailing market prices 
for the Common Stock and could impair the Company's ability to raise capital 
through the sale of its equity securities. 
    

                                 UNDERWRITING 

   
   Whale Securities Co., L.P. (the "Underwriter") has agreed, subject to the 
terms and conditions contained in the Underwriting Agreement, to purchase 
1,800,000 shares of Common Stock and 1,800,000 Warrants from the 
    

                                      40 
<PAGE>

   
Company. The Underwriter is committed to purchase and pay for all of the 
Common Stock and Warrants offered hereby if any of such securities are 
purchased. The Common Stock and Warrants are being offered by the 
Underwriter, subject to prior sale, when, as and if delivered to and accepted 
by the Underwriter and subject to approval of certain legal matters by 
counsel and to certain other conditions. 

   The Underwriter has advised the Company that it proposes to offer the 
Common Stock and Warrants to the public at the public offering prices set 
forth on the cover page of this Prospectus. The Underwriter may allow to 
certain dealers who are members of the National Association of Securities 
Dealer, Inc. (the "NASD") concessions, not in excess of $    per share of 
Common Stock and $    per Warrant, of which not in excess of $    per share 
of Common Stock and $    per Warrant may be reallowed to other dealers who 
are members of the NASD. 

   The Company has granted to the Underwriter an option, exercisable for 45 
days from the date of this Prospectus, to purchase up to 270,000 additional 
shares of Common Stock and/or 270,000 additional Warrants at the public 
offering prices set forth on the cover page of this Prospectus, less the 
underwriting discounts and commissions. The Underwriter may exercise this 
option in whole or, from time to time, in part, solely for the purpose of 
covering over-allotments, if any, made in connection with the sale of the 
shares of Common Stock and/or Warrants offered hereby. 

   The Company has agreed to pay to the Underwriter a non-accountable expense 
allowance of 3% of the gross proceeds of this offering, of which $50,000 has 
been paid as of the date of this Prospectus. The Company has also agreed to 
pay all expenses in connection with qualifying the shares of Common Stock and 
Warrants offered hereby for sale under the laws of such states as the 
Underwriter may designate, including expenses of counsel retained for such 
purpose by the Underwriter. 

   The Company has agreed to grant to the Underwriter and its designees 
warrants (the "Underwriter's Warrants") to purchase up to 180,000 shares of 
Common Stock at a purchase price of $6.60 per share and/or up to 180,000 
Warrants (each to purchase one share of Common Stock at $8.25 per share) at 
an exercise price of $.132 per Warrant. The Underwriter's Warrants may not be 
sold, transferred, assigned or hypothecated for one year from the date of 
this Prospectus, except to the officers and partners of the Underwriter and 
members of the selling group, and are exercisable during the five-year period 
commencing on the date of this Prospectus (the "Warrant Exercise Term"). 
During the Warrant Exercise Term, the holders of the Underwriter's Warrants 
can be expected to exercise them at a time when the Company would, in all 
likelihood, be able to obtain any needed capital on terms more favorable to 
the Company than those provided in the Underwriter's Warrants. Any profit 
realized by the Underwriter on the sale of the Underwriter's Warrants or the 
underlying securities may be deemed additional underwriting compensation. 
Subject to certain limitations and exclusions, the Company has agreed, at the 
request of the holders of a majority of the Underwriter's Warrants, at the 
Company's expense, to register the securities issuable upon exercise of the 
Underwriter's Warrants under the Securities Act on one occasion during the 
Warrant Exercise Term and to include such underlying securities in any 
appropriate Registration Statement which is filed by the Company during the 
seven years following the date of this Prospectus. 

   The Company has agreed, in connection with the exercise of the Warrants 
pursuant to solicitation (commencing one year from the date of this 
Prospectus), to pay to the Underwriter for bona fide services provided a fee 
of 5% of the exercise price for each Warrant exercised; provided, however, 
that the Underwriter will not be entitled to receive such compensation in 
Warrant exercise transactions in which (i) the market price of shares at the 
time of exercise is lower than the exercise price of the Warrants; (ii) the 
Warrants are held in any discretionary account; (iii) disclosure of 
compensation arrangements is not made, in addition to the disclosure provided 
in this Prospectus, in documents provided to holders of the Warrants at the 
time of exercise; (iv) the holder of the Warrants has not confirmed in 
writing that the Underwriter solicited such exercise; or (v) the solicitation 
of exercise of the Warrants was in violation of Rule 10b-6 promulgated under 
the Exchange Act. In addition to soliciting, either orally or in writing, the 
exercise of the Warrants, such bona fide services may also include 
disseminating information, either orally or in writing, to the holders of the 
Warrants about the Company or the market for the Company's securities, and 
assisting in the processing of the exercise of Warrants. 
    

   The Underwriter acted as placement agent in connection with the Bridge 
Financing and received $200,000 (representing 10% of the purchase price of 
the units) and a non-accountable expense allowance of $35,000. 

                                      41 
<PAGE>

   All of the officers and directors and shareholders of the Company holding 
an aggregate of 3,569,720 shares of the Common Stock (excluding the holders 
of 42,000 shares of Common Stock) have agreed that they will not sell any 
shares of Common Stock of the Company for a period of eighteen months after 
the date of this Prospectus without prior written consent of the Underwriter. 

   The Company has agreed to indemnify the Underwriter against certain 
liabilities, including liabilities under the Securities Act. 

   The Underwriter has informed the Company that it does not expect sales 
made to discretionary accounts to exceed 1% of the securities offered hereby. 

   
   Prior to this offering, there has been no public trading market for the 
Common Stock or the Warrants. Consequently, the initial public offering 
prices of the Common Stock and the Warrants has been determined by 
negotiations between the Company and the Underwriter. Among the factors 
considered in determining the offering price were the Company's financial 
condition and prospects, market prices of similar securities of comparable 
publicly-traded companies, certain financial and operating information of 
companies engaged in activities similar to those of the Company and the 
general condition of the securities market.

   The shares may be offered and sold from time to time as market conditions 
permit in the over-the-counter market, or otherwise, at prices and terms then 
prevailing or at prices related to the then-current market price, or in 
negotiated transactions. The shares may be sold by one or more of the 
following methods, without limitation: (a) a block trade in which a broker or 
dealer so engaged will attempt to sell the shares as agent but may position 
and resell a portion of the block as principal to facilitate the transaction; 
(b) purchases by a broker or dealer as principal and resale by such broker or 
dealer for its account pursuant to this Prospectus; (c) ordinary brokerage 
transactions and transactions in which the broker solicits purchases; and (d) 
face-to-face transactions between sellers and purchasers without a 
broker/dealer. In effecting sales, brokers or dealers engaged by the Selling 
Shareholders may arrange for other brokers or dealers to participate. Such 
brokers or dealers may receive commissions or discounts from Selling 
Shareholders in amounts to be negotiated. Such broker and dealers and any 
other participating brokers or dealers may be deemed to be "underwriters" 
within the meaning of the Securities Act, in connection with such sales.

                      REPORT OF INDEPENDENT ACCOUNTANTS 

To the Shareholders and Board of Directors of 
 HealthDesk Corporation: 

   We have audited the accompanying balance sheets of HealthDesk Corporation 
(a development stage company) as of December 31, 1994 and 1995, and the 
related statements of operations, shareholders' equity (deficit), and cash 
flows for the years then ended, and for the period from August 28, 1992 
(inception) to December 31, 1995. These financial statements are the 
responsibility of the Company's management. Our responsibility is to express 
an opinion on these financial statements based on our audits. 

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

   In our opinion, the financial statements referred to above present fairly, 
in all material respects, the financial position of HealthDesk Corporation as 
of December 31, 1994 and 1995, and the results of its operations and its cash 
flows for the years then ended, and for the period from August 28, 1992 
(inception) to December 31, 1995 in conformity with generally accepted 
accounting principles. 

   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 is still in the development stage and, 
therefore, has incurred losses from operations and negative cash flows from 
operating activities since inception. These conditions raise substantial 
doubt about the ability of the Company to continue as a going concern. 
Management's plans in regard to these matters are also discussed in Note 1. 
The financial statements do not include any adjustments that might result 
from the outcome of this uncertainty.

                            HEALTHDESK CORPORATION 
                        (A DEVELOPMENT STAGE COMPANY) 

                        NOTES TO FINANCIAL STATEMENTS 

1. ORGANIZATION AND BASIS OF PRESENTATION: 

   HealthDesk Corporation (the Company), a development stage company, is 
engaged in designing, developing and marketing HealthDesk(R) Online, a 
healthcare management and information system which enables consumers to take 
a more active role in their personal and family health. HealthDesk Online 
features easy-to-use Windows-based software designed to develop personal 
medical records and health management programs and access educational, health 
related information from the Company's private website and over the Internet. 

   The Company's financial statements have been prepared assuming the Company 
will continue as a going concern. The Company is still in the development 
stage and substantially all of its revenues were derived from certain 
development contracts relating to specific disease management modules in its 
initial product. Since inception, the Company has devoted a substantial 
effort to developing new products and has therefore incurred losses from 
operations and negative cash flows from operating activities since inception. 
These conditions raise substantial doubt about the ability of the Company to 
continue as a going concern. The Company is striving to achieve profitable 
operations by commercializing its products and obtaining contracts with 
potential sponsoring organizations. The Company is also actively seeking to 
raise additional capital through the offering of debt and common stock. 
However, there can be no assurance that the Company's efforts to achieve 
profitable operations or raise additional capital will be successful. The 
financial statements do not include any adjustments that might result from 
the outcome of this uncertainty. 

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: 

UNAUDITED INTERIM FINANCIAL INFORMATION: 

   The financial statements as of and for the nine month periods ended 
September 30, 1995 and 1996 are unaudited but, in the opinion of management, 
include all adjustments, consisting only of normal recurring accruals, 
necessary for a fair presentation of the results for such periods. The 
results of operations for the nine months ended September 30, 1996 are not 
necessarily indicative of results to be expected for the full year. 

REVENUE RECOGNITION: 

   During 1994 and 1995, the Company's revenues were generated primarily from 
two software development contracts. These revenues were recognized when the 
Company achieved designated milestones and received customer acceptance as 
specified in the related contracts. 

CASH AND CASH EQUIVALENTS: 

   Cash and cash equivalents include all cash balances, money market 
instruments, and other highly liquid investments with insignificant interest 
rate risk and original maturities of three months or less. 

SOFTWARE DEVELOPMENT COSTS: 

   Statement of Financial Accounting Standards No. 86, Accounting for the 
Costs of Computer Software to be Sold, Leased, or Otherwise Marketed (SFAS 
86), requires that software development costs be capitalized once the 
technological feasibility of the software product has been established. To 
date, such amounts eligible for capitalization have been insignificant and 
have been charged to product development expense in the period incurred. 

PROPERTY AND EQUIPMENT: 

   Property and equipment is stated at cost. Depreciation is calculated using 
the straight-line method over the estimated useful lives of three years for 
computer hardware and purchased computer software and five years for 
furniture and fixtures, and over the remaining term of the facility lease for 
leasehold improvements.

                          NOTES TO FINANCIAL STATEMENTS

2. Summary of Significant Accounting Policies:  - (Continued) 

   When assets are sold or retired, the cost and related accumulated 
depreciation are removed from the accounts and any resulting gain or loss is 
included in operations. Maintenance and repairs are charged to operations as 
incurred. 

INCOME TAXES: 

   Income taxes are accounted for in accordance with Statement of Financial 
Accounting Standards No. 109, Accounting for Income Taxes (SFAS No. 109). 
Under SFAS No. 109, deferred income tax liabilities and assets are determined 
based on the difference between the financial reporting amounts and tax bases 
of assets and liabilities that will result in taxable or deductible amounts 
in the future based on enacted tax laws and rates in effect for the years in 
which the differences are expected to affect taxable income. Valuation 
allowances are established when necessary to reduce deferred tax assets to 
the amounts expected to be realized. Income tax expense is the tax payable 
for the period and the change during the period in deferred tax assets and 
liabilities. 

COMPUTATION OF NET LOSS PER SHARE: 

   Net loss per share is computed using the weighted average number of common 
shares outstanding during each period. Common equivalent shares, consisting 
of stock options and convertible preferred stock are excluded from the 
computation, except as required by Securities and Exchange Commission Staff 
Accounting Bulletin No. 83 (SAB 83), because they would have an anti-dilutive 
impact. Pursuant to SAB 83, common shares and convertible preferred shares 
issued by the Company during the twelve months immediately preceding an 
offering date, plus the number of common equivalent shares which became 
issuable during the same period pursuant to the grant of stock options (using 
the treasury stock method and the proposed public offering price) have been 
included in the calculation of common and common equivalent shares as if they 
were outstanding for all periods presented. 

SHAREHOLDERS' EQUITY: 

   On September 19, 1996, the Company's Board of Directors approved a 1.2 
for 1 stock split of the Company's common and preferred stock. All share and 
per share amounts included in these financial statements have been restated to 
retroactively reflect the stock split. 

   On September 19, 1996, the Company also amended its Articles of 
Incorporation to increase its authorized shares of common stock and preferred 
stock to 17,000,000 and 3,000,000, respectively, and to increase the number 
of shares of preferred stock designated as Series A to 1,200,000. 

ACCOUNTING FOR STOCK-BASED COMPENSATION: 

   In October 1995, Statement of Financial Accounting Standards No. 123, 
"Accounting for Stock-Based Compensation" (FAS 123) was issued and is 
effective for the Company's 1996 year. The Company intends to continue to 
account for employee stock options in accordance with APB Opinion No. 25 and, 
accordingly, will comply with the pro forma disclosures required by FAS 123. 

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.

2. Summary of Significant Accounting Policies:  - (Continued) 

RECLASSIFICATIONS: 

   Certain prior year balances have been reclassified to conform to the 
current year's presentation. Such reclassifications had no impact on net loss 
or shareholders' deficit as previously reported. 

3. CONCENTRATIONS OF CREDIT RISK: 

   The Company places its temporary cash investments with one financial 
institution. The Company performs ongoing credit evaluations of its customers 
and generally does not require collateral. Two customers accounted for 
approximately 76% and 5%, respectively, of revenues in 1994 and 40% and 56%, 
respectively, in 1995. Additionally, one customer accounted for approximately 
96% and 92%, respectively, of revenues for the nine-month periods ended 
September 30, 1995 and 1996. 

4. PROPERTY AND EQUIPMENT: 

   Property and equipment at December 31, 1994 and 1995 and September 30, 
1996, consisted of the following:

5. INCOME TAXES: 

   The provision for income taxes for the years ended December 31, 1994 and 
1995, relates to current state income tax. The estimated tax effect of 
significant temporary differences and carryforwards that gave rise to 
deferred income tax assets as of December 31, 1994 and 1995, is as follows:

</TABLE>

   Due to the uncertainty of realization, a valuation allowance has been 
provided to eliminate the net deferred tax assets at both December 31, 1994 
and 1995. The increase in the valuation allowance was $122,000 and $487,500 
during the years ended December 31, 1994 and 1995, respectively. 

   As of December 31, 1995, the Company had net operating loss carryforwards 
of approximately $1,700,000 and $860,000 for federal income tax and 
California state franchise tax purposes, respectively. The federal 
carryforwards expire through 2010 (through 2000 for state carryforwards). As 
of December 31, 1995, the Company also has research and experimentation tax 
credit carryforwards of $35,000 and $24,000 for federal and state tax 
purposes, respectively. These carryforwards expire in the years ending 2007 
through 2009.

                          NOTES TO FINANCIAL STATEMENTS

5. Income Taxes:  - (Continued) 

   Pursuant to the provisions of the Tax Reform Act of 1986, utilization of 
these net operating loss and tax credit carryforwards will be subject to an 
annual limitation due to the occurrence of a greater than 50% change in the 
ownership of the Company during fiscal 1995 as it applies to net operating 
losses which occurred prior to the change in ownership. 

6. NOTES PAYABLE: 

   On May 23, 1994, the Company entered into a $500,000 convertible 
promissory note agreement with simple interest at the rate of 7% per annum. 
The agreement provided the holder with the option of converting the principal 
amount plus the accrued interest into shares of the Company's common stock at 
a conversion price of $3.33 per share prior to the due date. Both principal 
and accrued interest thereof were due and payable two years from the 
agreement date. Subsequent to May 23, 1996, the Company and the note holder 
reached an agreement on a revised due date (see Note 12). At December 31, 
1994 and 1995 and September 30, 1996, accrued interest relating to this note 
was $19,834, $54,833 and $81,083, respectively. The Company believes that the 
carrying amount of this note approximates fair value. 

   In July and August 1996, the Company issued two term notes (the Notes) to 
two existing shareholders and directors for $500,000. The Notes bear interest 
at 8% per annum and will convert into 100,000 shares of the Company's common 
stock on the earlier of the closing date of an initial public offering or 
March 31, 1997. 

7. COMMITMENTS AND CONTINGENCIES: 

LEASES: 

   The Company entered into a noncancellable lease for its office in January 
1996 which expires in early 1999. Additionally, the Company has other 
noncancelable operating leases expiring through November 2000. Total rent 
expense for 1994 and 1995 aggreated $17,438 and $32,688, respectively. 
Minimum future rentals under these operating leases as of December 31, 1995,

AGREEMENTS: 

   In May 1996, the Company entered into a cross-licensing agreement with 
another company. Pursuant to this agreement, the two companies granted each 
other a non-exclusive right to market the other party's principal product in 
exchange for a semiannual licensing fee of $25,000. 

   The Company has also entered into various agreements granting it a 
non-exclusive right to use products of third parties in exchange for 
royalties based on usage levels. The Company has incurred $16,667 in royalty 
expenses under these agreements as of September 30, 1996. 

   The Company has entered into various software and content agreements 
pursuant to which it is committed to pay, as of September 30, 1996, 
non-refundable minimum royalties of approximately $190,000.

LEGAL PROCEEDINGS: 

   The Company is subject to two complaints filed by former employees with 
the California Department of Fair Employment and Housing. Management intends 
to defend them vigorously. Since the financial impact of the ultimate outcome 
of these matters is neither probable nor estimable, no amounts have been 
accrued in these financial statements. 

8. EMPLOYEE BENEFIT PLANS: 

   On February 28, 1996, the Company adopted a 401(k) plan for employees. All 
employees who meet certain service requirements are eligible to participate. 
Matching contributions are at the discretion of the Company. As of September 
30, 1996, the Company had not elected to make any discretionary 
contributions. 

   On August 1, 1994, the Company commenced the deferral of the payment of a 
portion of all future compensation of the Company's president. During 1995, 
all amounts due were paid to the Company's president as part of an agreement 
to terminate his employment as discussed in Note 9.

   On April 8, 1993, the Company and a related entity (Spartina Corporation), 
which was wholly owned by the Company's president and director, entered into 
an agreement under which the related entity granted the Company a 
non-exclusive, royalty free license to use the source code of a certain 
software engine and tools in connection with the development of the Company's 
software products in the fields of health and medical management. The Company 
currently does not use any of this technology in the current product. 

   On August 31, 1995, the Company's president signed an agreement to 
terminate his employment with the Company. Under the agreement, the president 
received a cash payment in consideration for an agreement not to compete with 
the Company and the termination of options to purchase an aggregate of 
198,000 shares of the Company's common stock. In addition, Spartina 
Corporation assigned to the Company all of its right, title and interest in 
and to certain technology previously licensed by the Company from Spartina 
Corporation pursuant to the agreement discussed above. 

   During the period from June 7, 1995 through September 28, 1995, the 
Company issued two convertible promissory notes (the Notes) to two existing 
shareholders for $800,000. The Notes bore interest at 6% per annum. Interest 
expense relating to these Notes amounted to $5,005 during 1995. On September 
29, 1995, the principal of the Notes was converted at a rate of $1.04 per 
share into 768,000 shares of common stock of the Company.

9. Related Party Transactions:  - (Continued) 

   On August 15, 1995, the Company granted an option to acquire 96,000 shares 
of common stock at $1.04 per share to a board member and existing 
shareholder. The option was exercised on December 29, 1995 and the proceeds 
of $100,000 were received by the Company on January 8, 1996. 

   In December 1995, two principal shareholders and related Board members 
purchased 69,000 and 129,000 shares of the Company's Series A preferred stock 
for an aggregate purchase price of approximately $144,000 and $268,000, 
respectively, in connection with the Company's Series A financing. 

   As discussed in Note 6. in July and August 1996, the Company issued two 
term notes to two existing shareholders and related Board members. 

10. PREFERRED STOCK: 

   At December 31, 1995, the Company was authorized to issue 2,000,000 shares 
of preferred stock. Of the authorized preferred stock, 1,200,000 shares are 
designated as Series A. As of December 31, 1995, the Company had issued 
939,600 shares of Series A preferred stock for gross proceeds of $1,957,500. 
In February 1996, an additional 120,000 shares of Series A preferred stock 
were issued for gross proceeds of $250,000. 

   The preferred stock is convertible at the option of the holder, into the 
Company's common stock at a rate of one share of common stock for one share 
of preferred stock. The conversion rate for the preferred stock is subject to 
future adjustments. The preferred stock will automatically convert 
immediately upon the closing of an initial public offering of the Company's 
common stock with gross proceeds exceeding $5 million or upon the approval of 
the holders of at least two thirds of the outstanding shares of preferred 
stock. 

   Each share of preferred stock issued and outstanding has the number of 
votes equal to the number of shares of common stock into which such shares of 
preferred stock is convertible. The Series A preferred stock may receive 
noncumulative dividends in preference to holders of common stock, if and 
when, declared by the Board of Directors. 

   In the event of any liquidation or dissolution, the holders of preferred 
stock shall be entitled to receive $2.08 per share in preference to any 
distribution to holders of common stock. After payment has been made to the 
holders of the preferred stock, any remaining assets shall be distributed 
ratably among the holders of the preferred and common stock based on the 
number of common shares held or, in the case of preferred stock, the number 
of shares of common stock on an as if converted basis. If the Company's 
assets are insufficient to provide for the full preference amount for the 
preferred stock outstanding, then such assets shall be distributed ratably 
among the holders of the preferred stock in proportion to the preferential 
amount each such holder would have been entitled to receive. 

11. STOCK OPTIONS: 

   In June 1994, the Company adopted the 1994 Stock Option Plan (the Plan) 
under which eligible employees, directors, and consultants can receive 
options to purchase shares of the Company's common stock at a price generally 
not less than 100% and 85% of the fair value of the common stock on the date 
of the grant for incentive stock options and nonstatutory stock options, 
respectively. However, the Company never granted options at below fair value 
as determined by the Board of Directors. The Plan, as amended, allows for the 
issuance of a maximum of 840,000 shares of the Company's common stock. This 
number of shares of common stock has been reserved for issuance under the 
Plan. The options granted under the Plan are exercisable over a maximum term 
of ten years from the date of grant and vest immediately. Shares purchased 
under the Plan are subject to a right of repurchase by the Company at the 
original exercise price. This repurchase right lapses with respect to 25% of 
the shares upon completion of one year of service and the balance in equal 
successive monthly installments upon completion of each of the next 36 months 
of service. With respect to certain of the options issued, the repurchase 
right is eliminated in the event there is a change in control of the Company.

</TABLE>

   At September 30, 1996, 575,778 of the exercisable options are subject to 
the Company's repurchase provision. 

12. SUBSEQUENT EVENTS: 

   Subsequent to September 30, 1996 and through December 2, 1996, the Company 
granted 140,000 additional options to purchase shares of common stock at an 
exercise price of $5.00 per share. As of December 2, 1996, there were 768,050 
options outstanding under the Plan. 

   On December 2, 1996, the shareholders authorized the issuance of options 
to purchase up to a maximum of 950,000 shares of common stock under the Plan. 

   On October 11, 1996, the Company consummated a Bridge Financing pursuant 
to which it issued an aggregate of (i) $2,000,000 principal amount of 
promissory notes which bear interest at the rate of 9% per annum and are due 
on the earlier of the consummation of the Company's proposed initial public 
offering or October 11, 1997, and (ii) 400,000 shares of the Company's common 
stock. The effective interest rate for the Bridge Financing notes, assuming a 
one-year term, is 54% and, assuming a 60-day term is 279%. The Company will 
record the notes at a discount of $900,000, which discount will be allocated 
to the 400,000 shares of common stock issued. Additionally, $154,000 of debt 
issuance costs will be recorded in connection with the Bridge Financing. 

   On October 16, 1996, the Company used approximately $583,000 of the net 
proceeds from the Bridge Financing to repay the promissory note, including 
accrued interest (Note 6). 

13. PRO FORMA INFORMATION (UNAUDITED): 

   The pro forma information as of September 30, 1996, reflected in the 
accompanying balance sheet, gives effect to (i) the conversion of all 
outstanding shares of convertible preferred stock into 1,059,600 shares of 
common stock (Note 10); (ii) the consummation of the Bridge Financing (Note 
12) in October 1996 and the application of a portion of the proceeds to repay 
a note payable plus accrued interest (Note 6); and (iii) the issuance of 
100,000 shares of common stock upon conversion of $500,000 of convertible 
notes payable (Note 6).

                    INFORMATION NOT REQUIRED IN PROSPECTUS 

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS. 

   The California Corporations Code provides for the indemnification of 
directors, officers, employees and agents of the Corporation under certain 
circumstances set forth in section 317. Section 317 permits a corporation to 
indemnify its agents, typically directors and officers, for expenses incurred 
or settlements or judgments paid in connection with certain legal 
proceedings. Only those legal proceedings arising out of such persons' 
actions as agents of the corporation may be grounds for indemnification. 

   Whether or not indemnification may be paid in a particular case depends 
upon whether the agent wins, loses or settles the suit and upon whether a 
third party or the Corporation itself is the plaintiff. The section provides 
for mandatory indemnification, no matter who the plaintiff is, when an agent 
is successful on the merits of a suit. In all other cases, indemnification is 
permissive. 

   If the agent loses or settles a suit brought by a third party, he or she 
may be indemnified for expenses incurred and settlements or judgments paid. 
Such indemnification may be authorized upon finding that the agent acted in 
good faith and in a manner he or she reasonably believed to be in the best 
interests of the corporation. 

   If the agent loses or settles a suit brought by or on behalf of the 
corporation, his or her right to indemnification is more limited. If he or 
she is adjudged to be liable to the Corporation, the court in which such 
proceeding was held must determine whether it would be fair and reasonable to 
indemnify him or her for expenses which such court shall determine. If the 
agent settles such a suit with court approval, he or she may be indemnified 
for expenses incurred upon a finding that the agent acted in good faith and 
in a manner he or she reasonably believed to be in the best interest of the 
Corporation and, in addition, that he or she acted with the care, including 
reasonable inquiry of an ordinarily prudent person. 

   The indemnification discussed above may be authorized by a majority vote 
of the disinterested directors or shareholders (the person to be indemnified 
is excluded from voting his or her shares) or the court in which the 
proceeding was brought. The Corporation's Board of Directors makes all 
decisions regarding the indemnification of its officers and directors on a 
case-by-case basis. 

   Any provision in the Corporation's Articles of Incorporation or Bylaws 
contained in a shareholder or director resolution that indemnifies its 
officers or directors must be consistent with section 317. Moreover, such a 
provision may prohibit permissive, but not mandatory, indemnification as 
described above. Last, a corporation has the power to purchase indemnity 
insurance for its agents even if it would not have the power to indemnify 
them. 

   The Corporation's Articles authorize the Board of Directors to provide 
indemnification of its agents through bylaw provisions or indemnification 
agreements, or both, in excess of the indemnification otherwise permitted by 
section 317, subject to the limits on such excess indemnification set forth 
in section 204 of the California Corporations Code. 

   Insofar as indemnification for liabilities under the Securities Act of 
1933 may be permitted to directors, officers or persons controlling the 
Registrant pursuant to the foregoing provisions, the Registrant has been 
informed 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.

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES. 

   Since its incorporation in September 1992, the Registrant has issued 
securities without registration under the Securities Act of 1933, as amended 
(the "Act") in the following transactions (in each case giving retroactive 
effect to all subsequent stock splits): 

   The Registrant issued an aggregate of 165,600 shares of Common Stock in 
September 1992 to its 4 founders at $0.008 per share. In April 1993 the 
Registrant issued an additional 132,000 shares at $0.008 per share to 7 
investors including officers, employees and directors. From May 1993 to April 
1994, the Registrant issued an aggregate of 300,000 shares to 4 investors at 
$1.04 per share, including one director. In September 1995, the Registrant 
issued an aggregate of 768,000 shares of Common Stock to 2 investors, 
including one director, pursuant to their exercise of Convertible Notes at 
$1.04 per share. From December 1995 through February 1996, the Registrant 
issued an aggregate of 1,059,600 shares of Series A Preferred Stock to 27 
investors, including an individual who was then a director of the Company, at 
a purchase price of $2.08 per share (which will automatically convert into 
the same number of shares of Common Stock upon the consummation of this 
offering). During the current fiscal year, the Registrant issued 102,120 
shares of Common Stock to three individuals all of whom were employees or 
directors of the Registrant, upon the exercise of stock options previously 
issued under the Registrant's 1994 Founder's Stock Option Plan at an exercise 
price of $1.04 per share. In October 1996, the Registrant issued 40 Units, 
with each Unit consisting of 10,000 shares of Common Stock and a promissory 
note in the principal amount of $50,000. The Units were purchased by 35 
accredited investors in a private placement. 

   The sales and issuances of the Preferred Stock and Common Stock described 
above were deemed to be exempt from registration under the Securities Act in 
reliance upon Section 4(2) thereof as transactions not involving a public 
offering. The purchasers in such private offerings represented their 
intention to acquire the securities for investment only and not with a view 
to the distribution thereof and appropriate legends were affixed to the stock 
certificates issued in such transactions. All purchasers had adequate access, 
through their employment or other relationships, to sufficient information 
about the Registrant to make an informed investment decision. No underwriter 
was employed with respect to any such sales.

ITEM 28. UNDERTAKINGS. 

   Insofar as indemnification for liabilities arising under the Act may be 
permitted to directors, officers and controlling persons of the Registrant 
pursuant to the foregoing provisions, or otherwise, the Registrant has been 
advised that in the opinion of the Securities and Exchange Commission such 
indemnification is against public policy as expressed in the Act and is, 
therefore, unenforceable. In the event that a claim for indemnification 
against 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 of whether such 
indemnification by it is against public policy as expressed in the Act and 
will be governed by the final adjudication of such issue. 

   The undersigned Registrant undertakes that: 1) for purposes of determining 
any liability under the Act, the information omitted from the form of 
prospectus filed as part of this Registration Statement in reliance upon Rule 
430A and contained in the form of prospectus filed by the Registrant pursuant 
to Rule 421(b)(1) or (4) or 497(b) under the Act shall be deemed to be part 
of the Registration Statement as of the time it was declared 

                                      II-3
<PAGE>

effective and 2) for the purpose of determining any liability under the Act, 
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. 

   The undersigned Registrant hereby undertakes to provide to the 
Underwriters at the Closing, as specified in the Underwriting Agreement, 
certificates in such denominations and registered in such names as required 
by the Underwriters to permit prompt delivery to each purchaser.

   Pursuant to the requirements of the Securities Act of 1933, the Registrant 
certifies that it has reasonable grounds to believe that it meets all of the 
requirements for filing on Form SB-2 and has duly caused Amendment No. 3 to 
this Registration Statement to be signed on its behalf by the undersigned, 
thereunto duly authorized, in the City of Berkeley, State of California, on 
December 19, 1996.

650 Fifth Avenue                                            ______________, 1996

Ladies and Gentlemen:

                   HealthDesk Corporation, a California corporation (the
"Company"), proposes to issue and sell to Whale Securities Co., L.P. (the
"Underwriter") 2,000,000 shares of common stock, no par value (the "Offered
Shares"), which Offered Shares are presently authorized but unissued shares of
the common stock, no par value (individually, a "Common Share" and collectively
the "Common Shares"), of the Company. In addition, the Underwriter, in order to
cover over-allotments in the sale of the Offered Shares, may purchase up to an
aggregate of 300,000 Common Shares (the "Optional Shares"; the Offered Shares
and the Optional Shares are hereinafter sometimes collectively referred to as
the "Shares").
 The Shares are described in the Registration Statement, as defined below. The
Company also proposes to issue and sell to the Underwriter for its own account

Common Shares at an exercise price of $_____ per share (the "Underwriter's
Warrants"), which sale will be consummated in accordance with the terms and
conditions of the form of Underwriter's Warrant filed as an exhibit to the
Registration Statement (as hereinafter defined).

                  The Company hereby confirms its agreement with the Underwriter
as follows:

                  1. Purchase and Sale of Offered Shares. On the basis of the

and delivery will be made at ________, New York City time, on the third business
day following the Effective Date (the fourth business day following the
Effective Date in the event that trading of the Offered Shares commences on the
day following the Effective Date), the date and time of such payment and
delivery being herein called the "Closing Date." The certificates representing
the Offered Shares to be delivered will be in such denominations and registered

for inspection, checking and packaging at the office of the Company's transfer
agent or correspondent in New York City, _________________________,
_____________________ not less than one full business day prior to the Closing
Date.

                           (b) On the Closing Date, the Company will sell the
Underwriter's Warrants to the Underwriter or to the designees of the Underwriter
limited to officers and partners of the Underwriter, members of the selling
group and/or their officers, directors or partners (collectively, the
"Underwriter's Designees"). The Underwriter's Warrants will be in the form of,
and in accordance with, the provisions of the Underwriter's Warrant attached as
an exhibit to the Registration Statement. The aggregate purchase price for the
Underwriter's Warrants is $200.00. The Underwriter's Warrants will be restricted
from sale, transfer, assignment or hypothecation for a period of one year from
the Effective Date, except to the Underwriter's Designees. Payment for the
Underwriter's Warrant Agreement will be made to the Company by check or checks
payable to its order on the Closing Date against delivery of the certificates
representing the Underwriter's Warrants. The certificates representing the
Underwriter's Warrants will be in such denominations and such names as the
Underwriter may request prior to the Closing Date.

                  3.       Option to Purchase Optional Shares.

                           (a) For the purposes of covering any over-allotments
in connection with the distribution and sale of the Offered Shares as
contemplated by the Prospectus, the Underwriter is hereby granted an option to
purchase all or any part of the Optional Shares from the Company. The purchase
price to be paid for the Optional Shares will be the same price per Optional
Share as the price per Offered Share set forth in Section 1 hereof. The option
granted hereby may be exercised by the Underwriter as

Effective Date. The Underwriter will not be under any obligation to purchase any
Optional Shares prior to the exercise of such option.

                           (b) The option granted hereby may be exercised by the
Underwriter by giving oral notice to the Company, which must be confirmed by a
letter, telex or telegraph setting forth the number of Optional Shares to be
purchased, the date and time for delivery of and payment for the Optional Shares
to be purchased and stating that the Optional Shares referred to therein are to
be used for the purpose of covering over-allotments in connection with the
distribution and sale of the Offered Shares. If such notice is given prior to
the Closing Date, the date set forth therein for such delivery and payment will
not be earlier than either two full business days thereafter or the Closing
Date, whichever occurs later. If such notice is given on or after the Closing
Date, the date set forth therein for such delivery and payment will not be
earlier than two full business days thereafter. In either event, the date so set
forth will not be more than 15 full business days after the date of such notice.
The date and time set forth in such notice is herein called the "Option Closing
Date." Upon exercise of such option, the Company will become obligated to convey
to the Underwriter, and, subject to the terms and conditions set forth in
Section 3(d) hereof, the Underwriter will become obligated to purchase, the
number of Optional Shares specified in such notice.

                           (c) Payment for any Optional Shares purchased will be
made to the Company by wire transfer or certified or official bank check or
checks pay-able to its order in New York Clearing House funds, at the office of
the Underwriter, against delivery of the Optional Shares purchased to the
Underwriter. The certificates representing the Optional Shares to be delivered
will be in such denominations and registered in such names as the Underwriter
requests not less than two full business days prior to the Option Closing Date,
and will be made available to the Underwriter for inspection, checking and
packaging at the aforesaid office of the Company's transfer agent or
correspondent not less than one full business day prior to the Option Closing
Date.

                           (d) The obligation of the Underwriter to purchase and
pay for any of the Optional Shares is subject to the accuracy and completeness
(as of the date hereof and as of the Option Closing Date) of and compliance in
all material respects with the representations and warranties of the Company
herein, to the accuracy and completeness of the statements of the Company or its
officers made in any certificate or other document to be delivered by the
Company pursuant to this Agreement, to the performance in all material respects
by the Company of its obligations hereunder, to the satisfaction by the Company
of the conditions,

as of the date hereof and as of the Option Closing Date, set forth in Section
3(b) hereof, and to the delivery to the Underwriter of opinions, certificates
and letters dated the Option Closing Date substantially similar in scope to
those specified in Section 5, 6(b), (c), (d) and (e) hereof, but with each
reference to "Offered Shares" and "Closing Date" to be, respectively, to the
Optional Shares and the Option Closing Date.

                  4.       Representations and Warranties of the Company. The
Company represents and warrants to, and agrees with, the Underwriter that:

                           (a) The Company is a corporation duly organized,
validly existing and in good standing under the laws of the State of California,
with full power and authority, corporate and other, to own or lease and operate,
as the case may be, its properties, whether tangible or intangible, and to
conduct its business as described in the Registration Statement and to execute,
deliver and perform this Agreement and the Underwriter's Warrant Agreement and
to consummate the transactions contemplated hereby and thereby. The Company is
duly qualified to do business as a foreign corporation and is in good standing
in all jurisdictions wherein such qualification is necessary and failure so to
qualify could have a material adverse effect on the financial condition, results
of operations, business or properties of the Company. The Company has no
subsidiaries.

                           (b) This Agreement has been duly executed and
delivered by the Company and constitutes the valid and binding obligation of the
Company, and the Underwriter's Warrant Agreement, when executed and delivered by
the Company on the Closing Date, will be the valid and binding obligations of
the Company, enforceable against the Company in accordance with their respective
terms. The execution, delivery and performance of this Agreement and the
Underwriter's Warrant Agreement by the Company, the consummation by the Company
of the transactions herein and therein contemplated and the compliance by the
Company with the terms of this Agreement and the Underwriter's Warrant Agreement
have been duly authorized by all necessary corporate action and do not and will
not, with or without the giving of notice or the lapse of time, or both, (i)
result in any violation of the Articles of Incorporation or By-Laws, each as
amended, of the Company; (ii) result in a breach of or conflict with any of the
terms or provisions of, or constitute a default under, or result in the
modification or termination of, or result in the creation or imposition of any
lien, security interest, charge or encumbrance upon any of the properties or
assets of the Company pursuant to any indenture, mortgage, note, contract,
commitment or other agreement or instrument to which the Company is a party or
by which the Company or any of its properties or assets is or may be bound or
affected; (iii) violate any existing applicable law, rule, regulation, judgment,

mental agency or court, domestic or foreign, having jurisdiction over the
Company or any of its properties or business; or (iv) have any effect on any
permit, certification, registration, approval, consent order, license, franchise
or other authorization (collectively, the "Permits") necessary for the Company
to own or lease and operate its properties and to conduct its business or the
ability of the Company to make use thereof.

                           (c) No Permits of any court or governmental agency or
body, other than under the Securities Act of 1933, as amended (the "Act"), the
Regulations (as hereinafter defined) and applicable state securities or Blue Sky
laws, are required (i) for the valid authorization, issuance, sale and delivery
of the Shares to the Underwriter, and (ii) the consummation by the Company of
the transactions contemplated by this Agreement or the Underwriter's Warrant
Agreement.

                           (d) The conditions for use of a registration
statement on Form SB-2 set forth in the General Instructions to Form SB-2 have
been satisfied with respect to the Company, the transactions contemplated herein
and in the Registration Statement. The Company has prepared in conformity with
the requirements of the Act and the rules and regulations (the "Regulations") of
the Securities and Exchange Commission (the "Commission") and filed with the
Commission a registration statement (File No. 333-_______ ) on Form SB-2 and has
filed one or more amendments thereto, covering the registration of the Shares
and the Warrant Shares under the Act, including the related preliminary
prospectus or preliminary prospectuses (each thereof being herein called a
"Preliminary Prospectus") and a proposed final prospectus. Each Preliminary
Prospectus was endorsed with the legend required by Item 501(a)(5) of Regulation
S-B of the Regulations and, if applicable, Rule 430A of the Regulations. Such
registration statement including any documents incorporated by reference therein
and all financial schedules and exhibits thereto, as amended at the time it
becomes effective, and the final prospectus included therein are herein,
respectively, called the "Registration Statement" and the "Prospectus," except
that, (i) if the prospectus filed by the Company pursuant to Rule 424(b) of the
Regulations differs from the Prospectus, the term "Prospectus" will also include
the prospectus filed pursuant to Rule 424(b), and (ii) if the Registration
Statement is amended or such Prospectus is supplemented after the date the
Registration Statement is declared effective by the Commission (the "Effective
Date") and prior to the Option Closing Date, the terms "Registration Statement"
and "Prospectus" shall include the Registration Statement as amended or
supplemented.

                           (e) Neither the Commission nor, to the best of the
Company's knowledge, any state regulatory authority has issued any order
preventing or suspending the use of any Preliminary Prospectus or has instituted
or, to the best of the Company's knowledge, threatened to institute any
proceedings with respect to such an order.

<PAGE>

                           (f) The Registration Statement when it becomes
effective, the Prospectus (and any amendment or supplement thereto) when it is
filed with the Commission pursuant to Rule 424(b), and both documents as of the
Closing Date and the Option Closing Date, referred to below, will contain all
statements which are required to be stated therein in accordance with the Act
and the Regulations and will in all material respects conform to the
requirements of the Act and the Regulations, and neither the Registration
Statement nor the Prospectus, nor any amendment or supplement thereto, on such
dates, will contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that this representation and warranty does not apply to
statements or omissions made in reliance upon and in conformity with information
furnished in writing to the Company in connection with the Registration
Statement or Prospectus or any amendment or supplement thereto by the Under-
writer expressly for use therein.

                           (g) The Company had at the date or dates indicated
in the Prospectus a duly authorized and outstanding capitalization as set forth
in the Registration Statement and the Prospectus. Based on the assumptions
stated in the Registration Statement and the Prospectus, the Company will have
on the Closing Date the adjusted stock capitalization set forth therein. Except
as set forth in the Registration Statement or the Prospectus, on the Effective
Date and on the Closing Date, there will be no options to purchase, warrants or
other rights to subscribe for, or any securities or obligations convertible
into, or any contracts or commitments to issue or sell shares of the Company's
capital stock or any such warrants, convertible securities or obligations.
Except as set forth in the Prospectus, no holders of any of the Company's
securities has any rights, "demand," "piggyback" or otherwise, to have such
securities registered under the Act.

                           (h) The descriptions in the Registration Statement
and the Prospectus of contracts and other documents are accurate and present
fairly the information required to be disclosed, and there are no contracts or
other documents required to be described in the Registration Statement or the
Prospectus or to be filed as exhibits to the Registration Statement under the
Act or the Regulations which have not been so described or filed as required.

                           (i) Coopers & Lybrand LLP, the accountants who have
certified certain of the financial statements filed and to be filed with the
Commission as part of the Registration Statement and the Prospectus, are
independent public accountants within the meaning of the Act and Regulations.
The financial statements and schedules and the notes thereto filed as part of
the Registration Statement and included in the Prospectus are complete, correct
and present fairly the financial position of the Company as of the dates
thereof, and the results of operations and changes in financial position of the
Company for the periods indicated therein, all in conformity with generally
accepted accounting principles applied on a consistent basis throughout the
periods involved except as otherwise stated in the Registration Statement and
the Prospectus. The selected financial data set forth in the Registration
Statement and the Prospectus present fairly the information shown therein and
have been compiled on a basis consistent with that of the audited and unaudited
financial statements included in the Registration Statement and the Prospectus.

                           (j) The Company has filed with the appropriate
federal, state and local governmental agencies, and all appropriate foreign
countries and political subdivisions thereof, all tax returns, including
franchise tax returns, which are required to be filed or has duly obtained
extensions of time for the filing thereof and has paid all taxes shown on such
returns and all assessments received by it to the extent that the same have

purchase Common Shares have been duly authorized and validly issued. The

Except as set forth in the Registration Statement and the Prospectus, on the

issuable upon the exercise of the Underwriter's Warrants will not be subject to
personal liability solely by reason of being such holders. Neither the
Underwriter's Warrants nor the Common Shares issuable upon exercise thereof will
be subject to preemptive rights of any shareholder of the Company. The Common
Shares issuable upon exercise of the Underwriter's Warrants have been duly
reserved for issuance upon exercise of the Underwriter's Warrants in accordance
with the provisions of the Underwriter's Warrant Agreement. The Underwriter's
Warrants conform to the descriptions thereof contained in the Registration

or which question the validity of the capital stock of the Company or this
Agreement or of any action taken or to be taken by the Company pursuant to, or

enforceable rights to use all patents, patent applications, trademarks, service
marks, copyrights, rights, trade secrets, confidential information, processes
and formulations used or proposed to be used in the conduct of its business as

therefor; and, to the best of the Company's knowledge, no others have infringed

                           (s) Since the respective dates as of which
information is given in the Registration Statement and the Prospectus and the
Company's latest financial statements, the Company has not incurred any material
liability or obligation, direct or contingent, or entered into any material
transaction, whether or not incurred in the ordinary course of business, and has

otherwise than as set forth or contemplated in the Prospectus.

                           (t) The Company does not own any real property. The
Company has good title to all personal property (tangible and intangible) owned
by it, free and clear of all security interests, charges, mortgages, liens,
encumbrances and defects, except such as are described in the Registration
Statement and Prospectus or such as do not materially affect the value or
transferability of such property and do not interfere with the use of such
property made, or proposed to be made, by the Company. The leases, licenses or
other contracts or instruments under which the Company leases, holds or is
entitled to use any property, real or personal, are valid, subsisting and
enforceable only with such exceptions as are not material and do not interfere
with the use of such property made, or proposed to be made, by the Company, and

relating to its owned or leased properties. The Company has adequately insured
its properties against loss or damage by fire or other casualty and maintains,
in adequate amounts, such other insurance as is usually maintained by companies
engaged in the same or similar businesses located in its geographic area.

in accordance with its terms, and none of such contracts or instruments has
been assigned by the Company, and neither the Company, nor, to the best of the
Company's knowledge, any other party, is in default thereunder and, to the best
of the Company's knowledge, no event has occurred which, with the lapse of time

                           None of the material provisions of such contracts
or instruments violates any existing applicable law, rule, regulation, judgment,
order or decree of any governmental agency or court having jurisdiction over the

non-competition agreements between the Company and its officers, employees and

thereunder or any regulatory authority relating to the practice of medicine.

                           (y) To the best of the Company's knowledge, no labor
problem exists with any of the Company's employees or is imminent which could

LLP, counsel to the Underwriter ("Underwriter's Counsel"), all agreements,
certificates, correspondence and other items, documents and information
requested by such counsel's Corporate Review Memorandum dated ____________,

                           Any certificate signed by an officer of the
Company and delivered to the Underwriter or to Underwriter's Counsel shall be
deemed to be a representation and warranty by the Company to the Underwriter as
to the matters covered thereby.

                  5. Certain Covenants of the Company. The Company covenants
with the Underwriter as follows:

                           (a) The Company will not at any time, whether before
the Effective Date or thereafter during such period as the Prospectus is
required by law to be delivered in connection with the sales of the Shares by
the Underwriter or a dealer, file or publish any amendment or supplement to the
Registration Statement or Prospectus of which the Underwriter has not been
previously advised and furnished a copy, or to which the Underwriter shall
object in writing.

                           (b) The Company will use its best efforts to cause
the Registration Statement to become effective and will advise the Underwriter
immediately, and, if requested by the Underwriter, confirm such advice in
writing, (i) when the Registration Statement, or any post-effective amendment
to the Registration Statement or any supplemented Prospectus is filed with the
Commission; (ii) of the receipt of any comments from the Commission; (iii) of

of any Preliminary Prospectus, or of the suspension of the qualification of the
Shares for offering or sale in any jurisdiction, or of the initiation of any
proceedings for any of such purposes. The Company will use its best efforts to
prevent the issuance of any such stop order or of any order preventing or
suspending such use and to obtain as soon as possible the lifting thereof, if
any such order is issued.

<PAGE>

                           (c) The Company will deliver to the Underwriter,
without charge, from time to time until the Effective Date, as many copies of
each Preliminary Prospectus as the Underwriter may reasonably request, and the
Company hereby consents to the use of such copies for purposes permitted by the
Act. The Company will deliver to the Underwriter, without charge, as soon as the
Registration Statement becomes effective, and thereafter from time to time as
requested, such number of copies of the Prospectus (as supplemented, if the
Company makes any supplements to the Prospectus) as the Underwriter may
reasonably request. The Company has furnished or will furnish to the Underwriter
two signed copies of the Registration Statement as originally filed and of all
amendments thereto, whether filed before or after the Registration Statement
becomes effective, two copies of all exhibits filed therewith and two signed
copies of all consents and certificates of experts.

                           (d) The Company will comply with the Act, the
Regulations, the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and the rules and regulations thereunder so as to permit the continuance
of sales of and dealings in the Offered Shares and in any Optional Shares which
may be issued and sold. If, at any time when a prospectus relating to the Shares
is required to be delivered under the Act, any event occurs as a result of which
the Registration Statement and Prospectus as then amended or supplemented would
include an untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or if it shall be necessary to amend or
supplement the Registration Statement and Prospectus to comply with the Act or
the regulations thereunder, the Company will promptly file with the Commission,
subject to Section 5(a) hereof, an amendment or supplement which will correct
such statement or omission or which will effect such compliance.

                           (e) The Company will furnish such proper information
as may be required and otherwise cooperate in qualifying the Shares for offering
and sale under the securities or Blue Sky laws relating to the offering in such
jurisdictions as the Underwriter may reasonably designate, provided that no such
qualification will be required in any jurisdiction where, solely as a result
thereof, the Company would be subject to service of general process or to
taxation or qualification as a foreign corporation doing business in such
jurisdiction.

                           (f) The Company will make generally available to its
security holders, in the manner specified in Rule 158(b) under the Act, and
deliver to the Underwriter and Underwriter's Counsel as soon as practicable and
in any event not later than 45 days after the end of its fiscal quarter in which
the first anniversary date of the effective date of the Registration Statement
occurs, an earning statement meeting the requirements of Rule 158(a) under the
Act covering a period of at least 12 consecutive months beginning after the
effective date of the Registration Statement.

Company as the Underwriter may from time to time reasonably request and which
can be prepared or obtained by the Company without unreasonable effort or
expense. The Company will furnish to its shareholders annual reports containing
audited financial statements and such other periodic reports as it may determine
to be appropriate or as may be required by law.

                           (h) Neither the Company nor any person that 
controls, is controlled by or is under common control with the Company will take
any action designed to or which might be reasonably expected to cause or result
in the stabilization or manipulation of the price of the Common Shares.

                           In addition, at the Closing Date or the Option

for the Offered Shares or any Optional Shares three percent (3%) of the gross
proceeds of the offering (less the sum of $50,000 previously paid to the
Underwriter), as payment for the Underwriter's nonaccountable expense allowance
relating to the transactions contemplated hereby, which amount will include the
fees and expenses of Underwriter's Counsel (other than the fees and expenses of
Underwriter's Counsel relating to Blue Sky qualifications and registrations,
which, as provided for above, shall be in addition to the three percent (3%)
nonaccountable expense allowance and shall be payable directly by the Company to
Underwriter's Counsel on or prior to the Closing Date).

                           (j) If the transactions contemplated by this
Agreement or related hereto because the Company or Underwriter decides not to

reimburse the Underwriter for its accountable out-of-pocket expenses up to the
sum of $50,000, inclusive of $50,000 previously paid to the Underwriter by the
Company. In no event, however, will the Underwriter, in the event the offering
is terminated, be entitled to retain or receive more than an amount equal to its
actual accountable out-of-pocket expenses.

                           (k) The Company intends to apply the net proceeds
from the sale of the Shares for the purposes set forth in the Prospectus. No
portion of the net proceeds from the sale of the Shares will be used to repay
any indebtedness, except for the repayment of the Bridge Notes (as defined in
the Prospectus). The Company will file with the Commission all required reports
on Form S-R in accordance with the provisions of Rule 463 promulgated under the
Act and will provide a copy of each such report to the Underwriter and its
counsel.

                           (l) During the period of eighteen (18) months from
the date hereof, none of the Company's officers, directors or securityholders
will offer for sale or sell or otherwise dispose of, directly or indirectly, any
securities of the Company, in any manner whatsoever, whether pursuant to Rule
144 of the Regulations or otherwise, and no holder of registration rights
relating to buy securities of the Company will exercise any such registration
rights, in either case, without the prior written consent of the Underwriter.

                                      -15-
<PAGE>

                           (m) The Company will not file any registration
statement relating to the offer or sale of any of the Company's securities,
including any registration statement on Form S-8, during the eighteen (18)
months from the Effective Date, without the Underwriter's prior written consent.

                           (n) The Company maintains and will continue to
maintain a system of internal accounting controls sufficient to provide
reasonable assurances that: (i) transactions are executed in accordance with
management's general or specific authorization; (ii) transactions are recorded
as necessary in order to permit preparation of financial statements in
accordance with generally accepted accounting principles and to maintain 
accountability for assets; (iii) access to assets is permitted only in

Underwriter and its successors will have the right to designate a nominee for
election, at its or their option, either as a member of or a non-voting advisor
to the Board of Directors of the Company, and the Company will use its best
efforts to cause such nominee to be elected and continued in office as a
director of the Company or as such advisor until the expiration of five (5)
years from the Effective Date. Each of the Company's current officers, directors
and shareholders agrees to vote all of the Common Shares owned by such person or
entity so as to elect and continue in office such nominee of the Underwriter.
Following the election of such nominee as a director or advisor, such person
shall receive no more or less compensation than is paid to other non-officer
directors of the Company for attendance at meetings of the Board of Directors of
the Company and shall be entitled to receive reimbursement for all reasonable

                                      -16-
<PAGE>

costs incurred in attending such meetings including, but not limited to, food,
lodging and transportation. The Company agrees to indemnify and hold such
director or advisor harmless, to the maximum extent permitted by law, against
any and all claims, actions, awards and judgments arising out of his service as
a director or advisor and, in the event the Company maintains a liability
insurance policy affording coverage for the acts of its officers and directors,
to include such director or advisor as an insured under such policy. The rights
and benefits of such indemnification and the benefits of such insurance shall,
to the extent possible, extend to the Underwriter insofar as it may be or may be
alleged to be responsible for such director or advisor.

                                    If the Underwriter does not exercise its
option to designate a member of or advisor to the Company's Board of Directors,
the Underwriter shall nonetheless have the right to send a representative (who
need not be the same individual from meeting to meeting) to observe each meeting
of the Board of Directors. The Company agrees to give the Underwriter notice of
each such meeting and to provide the Underwriter with an agenda and minutes of
the meeting no later than it gives such notice and provides such items to the
directors.

                           (r) The Company shall retain a transfer agent for the
Common Shares, reasonably acceptable to the Underwriter, for a period of five
(5) years from the Effective Date. In addition, for a period of five (5) years
from the Effective Date, the Company, at its own expense, shall cause such
transfer agent to provide the Underwriter, if so requested in writing, with
copies of the Company's daily transfer sheets, and, when requested by the
Underwriter, a current list of the Company's securityholders, including a list
of the beneficial owners of securities held by a depository trust company and
other nominees.

                           (s) The Company hereby agrees, at its sole cost and
expense, to supply and deliver to the Underwriter and Underwriter's Counsel,
within a reasonable period from the date hereof, four bound volumes, including

the Company, enforceable in accordance with their respective terms, subject, as
to enforcement of remedies, to applicable bankruptcy, insolvency,
reorganization, moratorium and other laws affecting the rights of creditors
generally and the discretion of courts in granting equitable remedies and except
that enforceability of the indemnification provisions set forth in Section 7

limited by the federal securities laws or public policy underlying such laws.

                           (iii) The execution, delivery and performance of

to which the Company is a party or by which the Company or any of the Company's
properties or assets are or may be bound or affected; (C) violate any existing
applicable law, rule, regulation, judgment, order or decree of any governmental
agency or court, domestic or foreign, having jurisdiction over the Company or
any of the Company's properties or business; or (D) have any effect on any
Permit necessary for the Company to own or lease and operate its properties or
conduct its business or the ability of the Company to make use thereof.

                           (iv) To the best of Company Counsel's knowledge, no
Permits of any court or governmental agency or body (other than under the Act,
the Regulations and applicable state securities or Blue Sky laws) are required
for the valid authorization, issuance, sale and delivery of the Shares or the
Underwriter's Warrants to the Underwriter, and the consummation by the Company
of the transactions contemplated by this Agreement or the Underwriter's Warrant
Agreement.

                           (v) The Registration Statement has become effective
under the Act; to the best of Company Counsel's knowledge, no stop order
suspending the effectiveness of the Registration Statement has been issued, and

                           (vi) The Registration Statement and the Prospectus,
as of the Effective Date, and each amendment or supplement thereto as of its
effective or issue date (except for the financial statements and other financial
data included therein or omitted therefrom, as to which Company Counsel need not
express an opinion) comply as to form in all material respects with the
requirements of the Act and Regulations and the conditions for use of a
registration statement on Form SB-2 have been satisfied by the Company.

                           (vii) The descriptions in the Registration Statement
and the Prospectus of statutes, regulations, government classifications,
contracts and other documents (including opinions of such counsel); and the
response to Item 13 of Form SB-2 have been reviewed by Company Counsel, and,
based upon such review, are accurate in all material respects and present fairly
the information required to be disclosed, and there are no material statutes,
regulations or government classifications, or, to the best of Company Counsel's

                                    None of the material provisions of the
contracts or instruments described above violates any existing applicable law,
rule, regulation, judgment, order or decree of any governmental agency or court
having jurisdiction over the Company or any of its assets or business.

                           (viii) The outstanding Common Shares and Preferred
Shares and outstanding options and warrants to purchase Common Shares have been
duly authorized and validly issued. The outstanding Common Shares and Preferred
Shares are fully paid and nonassessable. The outstanding options and warrants to
purchase Common Shares constitute the valid and binding obligations of the
Company, enforceable in accordance with their terms. None of the outstanding
Common Shares or Preferred Shares or options or warrants to purchase Common
Shares has been issued in violation of the preemptive rights of any shareholder
of the Company. None of the holders of the outstanding Common Shares or
Preferred Shares is subject to personal liability solely by reason of being such
a holder. The offers and sales of the outstanding Common Shares and Preferred
Shares and outstanding options and warrants to purchase Common Shares were at
all relevant times either registered under the Act and the applicable state
securities or Blue Sky laws or exempt from such registration requirements. The
authorized Common Shares and Preferred Shares and outstanding options and
warrants to purchase Common Shares conform to the descriptions thereof contained
in the Registration Statement and Prospectus. To the best of Company Counsel's
knowledge, except as set forth in the Prospectus, no holders of any of the
Company's securities has any rights, "demand", "piggyback" or otherwise, to have
such securities registered under the Act.

                           (ix) The issuance and sale of the Shares have been
duly authorized and, when the Shares have been issued and duly delivered against
payment therefor as contemplated by this Agreement, the Shares will be validly
issued, fully paid and nonassessable, and the holders thereof will not be
subject to personal liability solely by reason of being such holders. The Shares
are not subject to preemptive rights of any shareholder of the Company. The
certificates representing the Shares are in proper legal form.

                           (x) The issuance and sale of the Common Shares
issuable upon exercise of the Underwriter's Warrants have been duly authorized
and, when such Common Shares have been duly delivered against payment therefor,
as contemplated by the Underwriter's Warrant Agreement, such Common Shares will
be validly issued, fully paid and nonassessable. Holders of Common Shares

                                      -22-

<PAGE>



issuable upon exercise of the Underwriter's Warrants will not be subject to
personal liability solely by reason of being such holders. Neither the
Underwriter's Warrants nor the Common Shares issuable upon exercise thereof will
be subject to preemptive rights of any shareholder of the Company. The Warrant
Shares issuable upon exercise of the Underwriter's Warrants have been duly
reserved for issuance upon exercise of the Underwriter's Warrants in accordance
with the provisions of the Underwriter's Warrant Agreement. The Underwriter's
Warrants conform to the descriptions thereof in the Registration Statement and
Prospectus.

                           (xi) Upon delivery of the Offered Shares to the
Underwriter against payment therefor as provided in this Agreement, the
Underwriter (assuming it is a bona fide purchaser within the meaning of the
Uniform Commercial Code) will acquire good title to the Offered Shares, free and
clear of all liens, encumbrances, equities, security interests and claims.

                           (xii) Assuming that the Underwriter exer cises the
over-allotment option to purchase any of the Optional Shares and makes payment
therefor in accordance with the terms of this Agreement, upon delivery of the
Optional Shares to the Underwriter hereunder, the Underwriter (assuming it is a
bona fide purchaser within the meaning of the Uniform Commercial Code) will
acquire good title to such Optional Shares, free and clear of any liens,
encumbrances, equities, security interests and claims.

                           (xiii) To the best of Company Counsel's knowledge,
there are no claims, actions, suits, proceedings, arbitrations, investigations
or inquiries before any governmental agency, court or tribunal, foreign or
domestic, or before any private arbitration tribunal, pending or threatened
against the Company, or involving the Company's properties or business, other
than as described in the Prospectus, such description being accurate, and other
than litigation incident to the kind of business conducted by the Company which,
individually and in the aggregate, is not material.

                           (xiv) The Company owns or possesses adequate and
enforceable rights to use all patents, patent applications, trademarks, service
marks, copyrights, rights, trade secrets, confidential information, processes
and formulations used or proposed to be used in the conduct of its business as
described in the Prospectus (collectively the "Intan gibles"); to the best of
Company Counsel's knowledge, the Company has not infringed and is not infringing
with the rights of others with respect to the Intangibles; and, to the best of
Company Counsel's knowledge, the Company has not received any notice that

                                      -23-


<PAGE>



it has or may have infringed, is infringing upon or is conflicting with the
asserted rights of others with respect to the Intangibles which might, singly or
in the aggregate, materially adversely affect its business, results of
operations or financial condition and such counsel is not aware of any licenses
with respect to the Intangibles which are required to be obtained by the
Company. The opinions described in this Section 6(b)(xiv) may be given by
Company Counsel in reliance on the opinion of an attorney, reasonably acceptable
to Underwriter's Counsel, practicing in the patent area.

                           (xv) Company Counsel has participated in reviews and
discussions in connection with the preparation of the Registration Statement and
the Prospectus, and in the course of such reviews and discussions and such other
investigation as Company Counsel deemed necessary, no facts came to its
attention which lead it to believe that (A) the Registration Statement (except
as to the financial statements and other financial data contained therein, as to
which Company Counsel need not express an opinion), on the Effective Date,
contained any untrue statement of a material fact required to be stated therein
or omitted to state any material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading, or that (B) the Prospectus (except as to the
financial statements and other financial data contained therein, as to which
Company Counsel need not express an opinion) contains any untrue statement of a
material fact or omits to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

                                    In rendering its opinion pursuant to this
Section 6(b), Company Counsel may rely upon the certificates of government
officials and officers of the Company as to matters of fact, provided that
Company Counsel shall state that they have no reason to believe, and do not
believe, that they are not justified in relying upon such opinions or such
certificates of government officials and officers of the Company as to matters
of fact, as the case may be.

                                    The opinion letter delivered pursuant to
this Section 6(b) shall state that any opinion given therein qualified by the
phrase "to the best of our knowledge" is being given by Company Counsel after
due investigation of the matters therein discussed.

                  (c) At the Closing Date, there will have been delivered to the
Underwriter a signed opinion of Underwriter's Counsel, dated as of the Closing
Date, to the effect that the opinions delivered pursuant to Section 6(b) hereof
appear on their face to be appropriately responsive to the requirements of this
Agreement, except to the extent waived by the Underwriter, specifying the same,
and with respect to such related matters as the Underwriter may require.

                  (d) At the Closing Date (i) the Registration Statement and the
Prospectus and any amendments or supplements thereto will contain all material
statements which are required to be stated therein in accordance with the Act
and the Regulations and will conform in all material respects to the
requirements of the Act and the Regulations, and neither the Registration
Statement nor the Prospectus nor any amendment or supplement thereto will
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading; (ii)
since the respective dates as of which information is given in the Registration
Statement and the Prospectus, there will not have been any material adverse

the Company from that set forth or contemplated in the Registration Statement

Prospectus indicate might occur after the Effective Date; (iii) since the
respective dates as of which information is given in the Registration Statement
and the Prospectus, there shall have been no material transaction, contract or

business, which would be required to be set forth in the Registration Statement
and the Prospectus, other than as set forth therein; and (iv) no action, suit or
proceeding at law or in equity will be pending or, to the best of the Company's
knowledge, threatened against the Company which is required to be set forth in
the Registration Statement and the Prospectus, other than as set forth therein,
and no proceedings will be pending or, to the best of the Company's knowledge,
threatened against the Company before or by any federal, state or other
commission, board or administrative agency wherein an unfavorable decision,
ruling or finding would materially adversely affect the business, property,
financial condition or results of operations of the Company, other than as set
forth in the Registration Statement and the Prospectus. At the Closing Date,
there will be delivered to the Underwriter a certificate signed by the Chairman
of the Board or the President or a Vice President of the Company, dated the
Closing Date, evidencing compliance with the provisions of this Section 6(d) and
stating that the representations and warranties of the Company set forth in
Section 4 hereof were accurate and complete in all material respects when made
on the date hereof and are accurate and complete in all material respects on the
Closing Date as if then made; that the Company has performed all covenants and
complied with all conditions required by this Agreement to be performed or
complied with by the Company prior to or as of the Closing Date; and that, as of
the Closing Date, no stop order suspending the effectiveness of the Registration
Statement has been issued and no proceedings for that purpose have been
initiated or, to the best of his knowledge, are contemplated or threatened. In
addition, the Underwriter will have received such other and further certificates
of officers of the Company as the Underwriter or Underwriter's Counsel may
reasonably request.

                  (e) At the time that this Agreement is executed and at the
Closing Date, the Underwriter will have received a signed letter from Cooper &
Lybrand LLP, dated the date such letter is to be received by the Underwriter and
addressed to it, confirming that it is a firm of independent public accountants
within the meaning of the Act and Regulations and stating that: (i) insofar as
reported on by them, in their opinion, the financial statements of the Company
included in the Prospectus comply as to form in all material respects with the
applicable accounting requirements of the Act and the applicable Regulations;
(ii) on the basis of procedures and inquiries (not constituting an examination
in accordance with generally accepted auditing standards) consisting of a
reading of the unaudited interim financial statements of the Company, if any,
appearing in the Registration Statement and the Prospectus and the latest
available unaudited interim financial statements of the Company, if more recent
than that appearing in the Registration Statement and Prospectus, inquiries of
officers of the Company responsible for financial and accounting matters as to
the transactions and events subsequent to the date of the latest audited
financial statements of the Company, and a reading of the minutes of meetings
of the shareholders, the Board of Directors of the Company and any committees of
the Board of Directors, as set forth in the minute books of the Company, nothing
has come to their attention which, in their judgment, would indicate that (A)
during the period from the date of the latest financial statements of the
Company appearing in the Registration Statement and Prospectus to a specified
date not more than three business days prior to the date of such letter, there
have been any decreases in net current assets or net assets as compared with
amounts shown in such financial statements or decreases in net sales or
decreases [increases] in total or per share net income [loss] compared with the
corresponding period in the preceding year or any change in the capitalization
or long-term debt of the Company, except in all cases as set forth in or
contemplated by the Registration Statement and the Prospectus, and (B) the
unaudited interim financial statements of the Company, if any, appearing in the
Registration Statement and the Prospectus, do not comply as to form in all
material respects with the applicable accounting requirements of the Act and the
Regulations or are not fairly presented in conformity with generally accepted
accounting principles and practices on a basis substantially consistent with the
audited financial statements included in the Registration Statement or the
Prospectus; and (iii) they have compared specific dollar amounts, numbers of
shares, numerical data, percentages of revenues and earnings, and other
financial information pertaining to the Company set forth in the Prospectus
(with respect to all dollar amounts, numbers of shares, percentages and other
financial information contained in the Prospectus, to the extent that such
amounts, numbers, percentages and information may be derived from the general
accounting records of the Company, and excluding any questions requiring an
interpretation by legal counsel) with the results obtained from the application
of specified readings, inquiries and other appropriate procedures (which
procedures do not constitute an examination in accordance with generally
accepted auditing standards) set forth in the letter, and found them to be in
agreement.

of the NASD to execute transactions (as principal or as agent) in the Shares,
and no proceedings for the purpose of taking such action shall have been
instituted or shall be pending, or, to the best of the Underwriter's or the
Company's knowledge, shall be contemplated by the Commission or the NASD. The
Company represents at the date hereof, and shall represent as of the Closing

counsel shall have been furnished with all such documents, certificates and
opinions as they may request for the purpose of enabling them to pass upon the

meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, from and
against any and all losses, claims, damages, expenses or liabilities, joint or
several (and actions in respect thereof), to which they or any of them may

otherwise, and, except as hereinafter provided, will reimburse the Underwriter
and each such person, if any, for any legal or other expenses reasonably
incurred by them or any of them in connection with investigating or defending
any actions, whether or not resulting in any liability, insofar as such losses,
claims, damages, expenses, liabilities or actions arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained
(i) in the Registration Statement, in any Preliminary Prospectus or in the
Prospectus (or the Registration Statement or Prospectus as from time to time
amended or supplemented) or (ii) in any application or other document executed
by the Company, or based upon written information furnished by or on behalf of
the Company, filed in any jurisdiction in order to qualify the Shares under the
securities laws thereof (hereinafter "application"), or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary in order to make the statements
therein not misleading, in light of the circumstances under which they were
made, unless such untrue statement or omission was made in such Registration
Statement, Preliminary Prospectus, Prospectus or application in reliance upon
and in conformity with information furnished in writing to the Company in
connection therewith by the Underwriter or any such person through the
Underwriter expressly for use therein; provided, however, that the indemnity
agreement contained in this Section 7(a) with respect to any Preliminary
Prospectus will not inure to the benefit of the Underwriter (or to the benefit
of any other person that may be indemnified pursuant to this Section 7(a)) if
(A) the person asserting any such losses, claims, damages, expenses or
liabilities purchased the Shares which are the subject thereof from the
Underwriter or other indemnified person; (B) the Underwriter or other 
indemnified person failed to send or give a copy of the Prospectus to such
person at or prior to the written confirmation of the sale of such Shares to
such person; and (C) the Prospectus did not contain any untrue statement or
alleged untrue statement or omission or alleged omission giving rise to such
cause, claim, damage, expense or liability.

                  (b) The Underwriter 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 Section 15 of the Act or Section 20(a) of the Exchange Act, from
and against any and all losses, claims, damages, expenses or liabilities, joint
or several (and actions in respect thereof), to which they or any of them may
become subject under the Act or under any other statute or at common law or
otherwise, and, except as hereinafter provided, will reimburse the Company and
each such director, officer or controlling person for any legal or other
expenses reasonably incurred by them or any of them in connection with
investigating or defending any actions, whether or not resulting in any
liability, insofar as such losses, claims, damages, expenses, liabilities or
actions arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained (i) in the Registration Statement, in any
Preliminary Prospectus or in the Prospectus (or the Registration Statement or
Prospectus as from time to time amended or supplemented) or (ii) in any
application (including any application for registration of the Shares under
state securities or Blue Sky laws), or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading, in light of the circumstances under which they were made, but only
insofar as any such statement or omission was made in reliance upon and in
conformity with information furnished in writing to the Company in connection
therewith by the Underwriter expressly for use therein.

                  (c) Promptly after receipt of notice of the commencement of
any action in respect of which indemnity may be sought against any indemnifying
party under this Section 7, the indemnified party will notify the indemnifying

                                      -29-


<PAGE>


party in writing of the commencement thereof, and the indemnifying party will,
subject to the provisions hereinafter stated, assume the defense of such action
(including the employment of counsel satisfactory to the indemnified party and
the payment of expenses) insofar as such action relates to an alleged liability
in respect of which indemnity may be sought against the indemnifying party.
After notice from the indemnifying party of its election to assume the defense
of such claim or action, the indemnifying party shall no longer be liable to the
indemnified party under this Section 7 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
if, in the reasonable judgment of the indemnified party or parties, it is
advisable for the indemnified party or parties to be represented by separate
counsel, the indemnified party or parties shall have the right to employ a
single counsel to represent the indemnified parties who may be subject to
liability arising out of any claim in respect of which indemnity may be sought
by the indemnified parties thereof against the indemnifying party, in which
event the fees and expenses of such separate counsel shall be borne by the
indemnifying party. Any party against whom indemnification may be sought under
this Section 7 shall not be liable to indemnify any person that might otherwise
be indemnified pursuant hereto for any settlement of any action effected without
such indemnifying party's consent, which consent shall not be unreasonably
withheld.

         8. Contribution. To provide for just and equitable contribution, if (i)
an indemnified party makes a claim for indemnification pursuant to Section 7
hereof (subject to the limitations thereof) and it is finally determined, by a
judgment, order or decree not subject to further appeal, that such claim for
indemnification may not be enforced, even though this Agreement expressly
provides for indemnification in such case; or (ii) any indemnified or
indemnifying party seeks contribution under the Act, the Exchange Act, or
otherwise, then the Company (including, for this purpose, any contribution made
by or on behalf of any director of the Company, any officer of the Company who
signed the Registration Statement and any controlling person of the Company) as
one entity and the Underwriter (including, for this purpose, any contribution by
or on behalf of each person, if any, who controls the Underwriter within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each
officer, director, partner, employee and agent of the Underwriter) as a second
entity, shall contribute to the losses, liabilities, claims, damages and
expenses whatsoever to which any of them may be subject, so that the Underwriter
is responsible for the proportion thereof equal to the percentage which the
underwriting discount per Share set forth on the cover page of the Prospectus

                                      -30-


<PAGE>



represents of the initial public offering price per Share set forth on the cover
page of the Prospectus and the Company is responsible for the remaining portion;
provided, how ever, that if applicable law does not permit such allocation,
then, if applicable law permits, other relevant equitable considerations such
as the relative fault of the Company and the Underwriter in connection with the
facts which resulted in such losses, liabilities, claims, damages and expenses
shall also be considered. The relative fault, in the case of an untrue 
statement, alleged untrue statement, omission or alleged omission, shall be
determined by, among other things, whether such state ment, alleged statement,
omission or alleged omission relates to information supplied by the Company or
by the Underwriter, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement, alleged
statement, omission or alleged omission. The Company and the Underwriter agree
that it would be unjust and inequitable if the respective obligations of the
Company and the Underwriter for contribution were determined by pro rata or per
capita allocation of the aggregate losses, liabilities, claims, damages and
expenses or by any other method of allocation that does not reflect the
equitable considerations referred to in this Section 8. No person guilty of a
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
will be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation. For purposes of this Section 8, each person, if
any, who controls the Underwriter within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act and each officer, director, partner, employee
and agent of the Underwriter will have the same rights to contribution as the
Underwriter, and each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each
officer of the Company who has signed the Registration Statement and each
director of the Company will have the same rights to contribution as the
Company, subject in each case to the provisions of this Section 8. Anything in
this Section 8 to the contrary notwithstanding, no party will be liable for
contribution with respect to the settlement of any claim or action effected
without its written consent. This Section 8 is intended to supersede, to the
extent permitted by law, any right to contribution under the Act or the Exchange
Act or otherwise available.

         9. Survival of Indemnities, Contribution, Warranties and
Representations. The respective indemnity and contribution agreements of the
Company and the Underwriter contained in Sections 7 and 8 hereof, and the
representations and warranties of the Company contained herein shall remain
operative and in full force and effect, regardless of any termination or
cancellation of this Agreement or any investigation made by or on behalf of the
Underwriter, the Company or any of its directors and officers, or any
controlling person referred to in said Sections, and shall survive the delivery
of, and payment for, the Shares.

         10. Termination of Agreement.

                  (a) The Company, by written or telegraphic notice to the
Underwriter, or the Underwriter, by written or telegraphic notice to the
Company, may terminate this Agreement prior to the earlier of (i) 11:00 A.M.,
New York City time, on the first full business day after the Effective Date; or
(ii) the time when the Underwriter, after the Registration Statement becomes
effective, releases the Offered Shares for public offering. The time when the
Underwriter "releases the Offered Shares for public offering" for the purposes
of this Section 10 means the time when the Underwriter releases for publication
the first newspaper advertisement, which is subsequently published, relating to
the Offered Shares, or the time when the Underwriter releases for delivery to
members of a selling group copies of the Prospectus and an offering letter or an
offering telegram relating to the Offered Shares, whichever will first occur.

                                      -31-
<PAGE>

                  (b) This Agreement, including without limitation, the
obligation to purchase the Shares and the obligation to purchase the Optional
Shares after exercise of the option referred to in Section 3 hereof, are subject
to termination in the absolute discretion of the Underwriter, by notice given to
the Company prior to delivery of and payment for all the Offered Shares or such
Optional Shares, as the case may be, if, prior to such time, any of the
following shall have occurred: (i) the Company withdraws the Registration
Statement from the Commission or the Company does not or cannot expeditiously
proceed with the public offering; (ii) the representations and warranties in 
Section 4 hereof are not materially correct or cannot be complied with; (iii)
trading in securities generally on the New York Stock Exchange or the American
Stock Exchange will have been suspended; (iv) limited or minimum prices will
have been established on either such Exchange; (v) a banking moratorium will
have been declared either by federal or New York State authorities; (vi) any
other restrictions on transactions in securities materially affecting the free
market for securities or the payment for such securities, including the Offered
Shares or the Optional Shares, will be established by either of such Exchanges,
by the Commission, by any other federal or state agency, by action of the
Congress or by Executive Order; (vii) trading in any securities of the Company
shall have been suspended or halted by any national securities exchange, the
NASD or the Commission; (viii) there has been a materially adverse change in the
condition (financial or otherwise), prospects or obligations of the Company;
(ix) the Company will have sustained a material loss, whether or not insured, by
reason of fire, flood, accident or other calamity; (x) any action has been taken
by the government of the United States or any department or agency thereof
which, in the judgment of the Underwriter, has had a material adverse effect
upon the market or potential market for securities in general; or (xi) the
market for securities in general or political, financial or economic conditions
will have so materially adversely changed that, in the judgment of the
Underwriter, it will be impracticable to offer for sale, or to enforce contracts
made by the Underwriter for the resale of, the Offered Shares or the Optional
Shares, as the case may be.

                  (c) If this Agreement is terminated pursuant to Section 6
hereof or this Section 10 or if the purchases provided for herein are not
consummated because any condition of the Underwriter's obligations hereunder is
not satisfied or because of any refusal, inability or failure on the part of the
Company to comply with any of the terms or to fulfill any of the conditions of
this Agreement, or if for any reason the Company shall be unable to or does not
perform all of its obligations under this Agreement, the Company will not be
liable to the Underwriter for damages on account of loss of anticipated profits
arising out of the transactions covered by this Agreement, but the Company will
remain liable to the extent provided in Sections 5(j), 7, 8 and 9 of this
Agreement.

                  WARRANT AGREEMENT dated as of __________, 1997, by and among 
HealthDesk Corporation, a Washington corporation (the "Company"), Whale 
Securities, Co., L.P. (the "Underwriter") and American Stock Transfer and Trust
Company, as warrant agent (hereinafter called the "Warrant Agent").
                  WHEREAS, the Company proposes to issue and sell to the public
up to 1,800,000 shares of the common stock of the Company, no par value
(hereinafter, together with the stock of any other class to which such shares
may hereafter have been changed, called "Common Stock"), and up to 1,800,000
Common Stock Purchase Warrants (the "Warrants");
                  WHEREAS, each Warrant will entitle the holder to pur-
chase one share of Common Stock;
                  WHEREAS, the Company desires the Warrant Agent to act on
behalf of the Company, and the Warrant Agent is willing to so act, in connection
with the issuance, registration, transfer, exchange and exercise of the
Warrants;
                  NOW, THEREFORE, in consideration of the premises and the
mutual agreements herein set forth, the parties hereto agree as follows:
                  Section 1. Appointment of Warrant Agent. The Company hereby
appoints the Warrant Agent to act as Warrant Agent for the Company in accordance
with the instructions hereinafter set forth in this Agreement, and the Warrant
Agent hereby accepts such appointment.



<PAGE>




                  Section 2. Form of Warrant. The text of the Warrants and of
the form of election to purchase Common Stock to be printed on the reverse
thereof shall be substantially as set forth in Exhibit A attached hereto. Each
Warrant shall entitle the registered holder thereof to purchase one share of
Common Stock at a purchase price of five Dollars ($5.00), at any time from
___________, 1998 until 5:00 p.m. Eastern time, on __________, 2002 (the
"Warrant Exercise Period"). The warrant price and the number of shares of Common
Stock issuable upon exercise of the Warrants are subject to adjustment upon the
occurrence of certain events, all as hereinafter provided. The Warrants shall be
executed on behalf of the Company by the manual or facsimile signature of the
present or any future Chief Executive Officer, President or Vice President of
the Company, attested to by the manual or facsimile signature of the present or
any future Secretary or Assistant Secretary of the Company.
                  Warrants shall be dated as of the issuance by the Warrant
Agent either upon initial issuance or upon transfer or exchange.
                  In the event the aforesaid expiration dates of the Warrants
fall on a Saturday or Sunday, or on a legal holiday on which the New York Stock
Exchange is closed, then the Warrants shall expire at 5:00 p.m. Eastern time on
the next succeeding business day.

                                       -2-




<PAGE>



                  Section 3. Countersignature and Registration. The Warrant
Agent shall maintain books for the transfer and registration of the Warrants.
Upon the initial issuance of the Warrants, the Warrant Agent shall issue and
register the Warrants in the names of the respective holders thereof. The
Warrants shall be countersigned manually or by facsimile by the Warrant Agent
(or by any successor to the Warrant Agent then acting as warrant agent under
this Agreement) and shall not be valid for any purpose unless so countersigned.
Warrants may, however, be so countersigned by the Warrant Agent (or by its
successor as 6 Warrant Agent) and be delivered by the Warrant Agent,
notwithstanding that the persons whose manual or facsimile signatures appear
thereon as proper officers of the Company shall have ceased to be such officers
at the time of such countersignature or delivery.
                  Section 4. Transfers and Exchanges. The Warrant Agent shall
transfer, from time to time, any outstanding Warrants upon the books to be
maintained by the Warrant Agent for that purpose, upon surrender thereof for
transfer properly endorsed or accompanied by appropriate instructions for
transfer. Upon any such transfer, a new Warrant shall be issued to the
transferee and the surrendered Warrant shall be cancelled by the Warrant Agent.
Warrants so cancelled shall be delivered by the Warrant Agent to the Company
from time to time upon request. Warrants may be exchanged at the option of the
holder thereof, when surrendered at the office of the Warrant Agent, for another

                                      -3-
<PAGE>


Warrant, or other Warrants of different denominations of like tenor and 
representing in the aggregate the right to purchase a like number of shares of 
Common Stock.
                  Section 5.  Exercise of Warrants; Payment of Warrant
Solicitation Fee.
                      (a) Subject to the provisions of this
Agreement, each registered holder of Warrants shall have the right, which may be
exercised commencing at the opening of business on the first day of the Warrant
Exercise Period, to purchase from the Company (and the Company shall issue and
sell to such registered holder of Warrants) the number of fully paid and
non-assessable shares of Common Stock specified in such Warrants upon surrender
of such Warrants to the Company at the office of the Warrant Agent, with the
form of election to purchase on the reverse thereof duly filled in and signed,
and upon payment to the Company of the warrant price, determined in accordance
with the provisions of Sections 9 and 10 of this Agreement, for the number of
shares of Common Stock in respect of which such Warrants are then exercised.
Payment of such warrant price shall be made in cash or by certified check or
bank draft to the order of the Company. Subject to Section 6, upon such
surrender of Warrants and payment of the warrant price, the Company shall issue
and cause to be delivered with all reasonable dispatch to or upon the written
order of the registered holder of such Warrants and in such name or names as

                                      -4-
<PAGE>

such registered holder may designate, a certificate or certificates for the
number of full shares of Common Stock so purchased upon the exercise of such
Warrants. Such certificate or certificates shall be deemed to have been issued,
and any person so designated to be named therein shall be deemed to have become
a holder of record of such shares of Common Stock, as of the date of the
surrender of such Warrants and payment of the warrant price as aforesaid. The
rights of purchase represented by the Warrants shall be exercisable, at the
election of the registered holders thereof, either as an entirety or from time
to time for a portion of the shares specified therein and, in the event that any
Warrant is exercised in respect of less than all of the shares of Common Stock
specified therein at any time prior to the date of expiration of the Warrants, a
new Warrant or Warrants will be issued to the registered holder for the
remaining number of shares of Common Stock specified in the Warrant so
surrendered, and the Warrant Agent is hereby irrevocably authorized to
countersign and to deliver the required new Warrants pursuant to the provisions
of this Section and of Section 3 of this Agreement and the Company, whenever
requested by the Warrant Agent, will supply the Warrant Agent with Warrants duly
executed on behalf of the Company for such purpose. Anything in the foregoing to
the contrary notwithstanding, no Warrant will be exercisable unless at the time
of exercise the Company has filed with the Securities and Exchange Commission a

                                      -5-

registration statement under the Securities Act of 1933, as amended (the "Act"),
covering the shares of Common Stock issuable upon exercise of such Warrant and
such shares have been so registered or qualified or deemed to be exempt under
the securities laws of the state of residence of the holder of such Warrant. The
Company shall use its best efforts to have all shares so registered or qualified
on or before the date on which the Warrants become exercisable. 
                      (b) If at the time of exercise of any Warrant after (i)
________, 1998 (i) the market price of the Company's Common Stock is equal to or
greater than the then purchase price of the Warrant, (ii) the exercise of the
Warrant is solicited by the Underwriter at such time while the Underwriter is a
member of the National Association of Securities Dealers, Inc. ("NASD"), (iii)
the Warrant is not held in a discretionary account, (iv) disclosure of the
compensation arrangement is made in documents provided to the holders of the
Warrants; and (v) the solicitation of the exercise of the Warrant is not in
violation of Rule 10b-6 (as such rule or any successor rule may be in effect as
of such time of exercise) promulgated under the Securities Exchange Act of 1934,
then the Underwriter shall be entitled to receive from the Company upon exercise
of each of the Warrant(s) so exercised a fee of five percent (5%) of the
aggregate price of the Warrants so exercised (the "Exercise Fee"). The
procedures for payment of the warrant solicitation fee are set forth in Section
5(c) below.

                      (c) (1) Within five (5) days of the last day of each month
commencing with _______, 1998 the Warrant Agent will notify the Underwriter of
each Warrant Certificate which has been properly completed for exercise by
holders of Warrants during the last month. The Company and Warrant Agent shall
determine, in their sole and absolute discretion, whether a Warrant Certificate
has been properly completed. The Warrant Agent will provide the Underwriter with
such information, in connection with the exercise of each Warrant, as the
Underwriter shall reasonably request.
                                    (2) The Company hereby authorizes and
instructs the Warrant Agent to deliver to the Underwriter the Exercise Fee
promptly after receipt by the Warrant Agent from the Company of a check payable
to the order of the Underwriter in the amount of the Exercise Fee. The Warrant
Agent shall not issue the shares of Common Stock issuable upon exercise of the
Warrants until receipt and forwarding of such check to the Underwriter. In the
event that an Exercise Fee is paid to the Underwriter with respect to a Warrant
which the Company or the Warrant agent determines is not properly completed for
exercise or in respect of which the Underwriter is not entitled to an Exercise
Fee, the Underwriter will promptly return such Exercise Fee to the Warrant Agent
which shall forthwith return such fee to the Company.

                  The Underwriter and the Company may at any time, after
____________, 1998, and during business hours, examine the records of the
Warrant Agent, including its ledger of original Warrant certificates returned to
the Warrant Agent upon exercise of Warrants. Notwithstanding any provision to
the contrary, the provisions of paragraphs 5(b) and 5(c) may not be modified,
amended or deleted without the prior written consent of the Underwriter.
                  Section 6. Payment of Taxes. The Company will pay any
documentary stamp taxes attributable to the initial issuance of Common Stock
issuable upon the exercise of Warrants; provided, however, that the Company
shall not be required to pay any tax which may be payable in respect of any
transfer involved in the issue or delivery of any certificates of shares of
Common Stock in a name other than that of the registered holder of Warrants in
respect of which such shares are issued, and in such case neither the Company
nor the Warrant Agent shall be required to issue or deliver any certificate for
shares of Common Stock or any Warrant until the person requesting the same has
paid to the Company the amount of such tax or has established to the Company's
satisfaction that such tax has been paid.
                  Section 7. Mutilated or Missing Warrants. In case any of the
Warrants shall be mutilated, lost, stolen or destroyed, the Company may, in
its discretion, issue and the Warrant Agent shall countersign and deliver in
exchange and substitution for and upon cancellation of the mutilated Warrant,
or in lieu of and in substitution for the Warrant lost, stolen or destroyed, a
new Warrant of like tenor and representing an equivalent right or interest, but
only upon receipt of evidence satisfactory to the Company and the Warrant Agent

                                      -8-
<PAGE>

of such loss, theft or destruction and, in case of a lost, stolen or destroyed
Warrant, indemnity, if requested, also satisfactory to them. Applicants for such
substitute Warrants shall also comply with such other reasonable regulations and
pay such reasonable charges as the Company or the Warrant Agent may prescribe.
                  Section 8. Reservation of Common Stock. There have been
reserved, and the Company shall at all times keep reserved, out of the
authorized and unissued shares of Common Stock, a number of shares of Common
Stock sufficient to provide for the exercise of the rights of purchase
represented by the Warrants, and the transfer agent for the shares of Common
Stock and every subsequent transfer agent for any shares of the Company's Common
Stock issuable upon the exercise of any of the rights of purchase aforesaid are
irrevocably authorized and directed at all times to reserve such number of
authorized and unissued shares of Common Stock as shall be required for such
purpose. The Company agrees that all shares of Common Stock issued upon exercise
of the Warrants shall be, at the time of delivery of the certificates of such
shares, validly issued and outstanding, fully paid and non-assessable and listed
on any national securities exchange upon which the other shares of Common Stock
are then listed. So long as any unexpired Warrants remain outstanding, the
Company will file such post-effective amendments to the registration statement
(Form SB-2, Registration No. 333-14519) (the "Registration Statement") filed
pursuant to the Act with respect to the Warrants (or other appropriate
registration statements or post-effective amendment or supplements) as may be
necessary to permit it to deliver to each person exercising a Warrant, a
prospectus meeting the requirements of Section 10(a)(3) of the Act and otherwise

                                      -9-
<PAGE>


complying therewith, and will deliver such a prospectus to each such person. To
the extent that during any period it is not reasonably likely that the Warrants
will be exercised, due to market price or otherwise, the Company need not file
such a post-effective amendment during such period. The Company will keep a copy
of this Agreement on file with the transfer agent for the shares of Common Stock
and with every subsequent transfer agent for any shares of the Company's Common
Stock issuable upon the exercise of the rights of purchase represented by the
Warrants. The Warrant Agent is irrevocably authorized to requisition from time
to time from such transfer agent stock certificates required to honor
outstanding Warrants. The Company will supply such transfer agent with duly
executed stock certificates for that purpose. All Warrants surrendered in the
exercise of the rights thereby evidenced shall be cancelled by the Warrant Agent
and shall thereafter be delivered to the Company, and such cancelled Warrants

                                      -10-
<PAGE>


shall constitute sufficient evidence of the number of shares of Common Stock
which have been issued upon the exercise of such Warrants. Promptly after the
date of expiration of the Warrants, the Warrant Agent shall certify to the
Company the total aggregate amount of Warrants then outstanding, and thereafter
no shares of Common Stock shall be subject to reservation in respect of such
Warrants which shall have expired.

                  Section 9.  Warrant Price; Adjustments.
                           (a)  The warrant price at which Common Stock shall
be purchasable upon the exercise of the Warrants shall be $5.00 per share or
after adjustment, as provided in this Section, shall be such price as so
adjusted (the "Warrant Price").
                           (b) The Warrant Price shall be subject to adjustment
from time to time as follows:
                                    (i)  In case the Company shall at any time
after the date hereof pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock, then upon such dividend or distribution
the Warrant Price in effect immediately prior to such dividend or distribution
shall forthwith be reduced to a price determined by dividing:
                                            (A)  an amount equal to the total 
number of shares of Common Stock outstanding immediately prior to such dividend
or distribution multiplied by the Warrant Price in effect immediately prior to
such dividend or distribution, by

                                      -11-


<PAGE>



                                            (B)  the total number of shares of
Common Stock outstanding immediately after such issuance or sale.
                                    For the purposes of any computation to be
made in accordance with the provisions of this Section 9(b)(i), the following
provisions shall be applicable: Common Stock issuable by way of dividend or
other distribution on any stock of the Company shall be deemed to have been
issued immediately after the opening of business on the date following the date
fixed for the determination of stockholders entitled to receive such dividend or
other distribution.
                                    (ii)  In case the Company shall at any time
subdivide or combine the outstanding Common Stock, the Warrant Price shall
forthwith be proportionately decreased in the case of subdivision or increased
in the case of combination to the nearest one cent. Any such adjustment shall
become effective at the time such subdivision or combination shall become
effective.
                                    (iii) Within a reasonable time after the
close of each quarterly fiscal period of the Company during which the Warrant
Price has been adjusted as herein provided, the Company shall:
                                            (A)  file with the Warrant Agent a
certificate signed by the Chief Executive Officer, President or Vice President 
of the Company and by the Treasurer or Assistant Treasurer or the Secretary or 
an Assistant Secretary of the Company, showing in detail the facts requiring 
all such adjustments occurring during such period and the Warrant Price
after each such adjustment; and

                                      -12-
<PAGE>

                                            (B)  the Warrant Agent shall have no
duty with respect to any such certificate filed with it except to keep the same
on file and available for inspection by holders of Warrants during reasonable
business hours, and the Warrant Agent may conclusively rely upon the latest
certificate furnished to it hereunder. The Warrant Agent shall not at any time
be under any duty or responsibility to any holder of a Warrant to determine
whether any facts exist which may require any adjustment of the Warrant Price,
or with respect to the nature or extent of any adjustment of the Warrant Price
when made, or with respect to the method employed in making any such adjustment,
or with respect to the nature or extent of the property or securities
deliverable hereunder. In the absence of a certificate having been furnished,
the Warrant Agent may conclusively rely upon the provisions of the Warrants with
respect to the Common Stock deliverable upon the exercise of the Warrants and
the applicable Warrant Price thereof.

                                            (iv) Notwithstanding anything
contained herein to the contrary, no adjustment of the Warrant Price shall be
made if the amount of such adjustment shall be less than $.05, but in such case
any adjustment that would otherwise be required then to be made shall be carried

                                      -13-
<PAGE>

forward and shall be made at the time and together with the next subsequent
adjustment which, together with any adjustment so carried forward, shall amount
to not less than $.02.
                           (v)  In the event that the number of outstanding
shares of Common Stock is increased by a stock dividend payable in Common Stock
or by a subdivision of the outstanding Common Stock, then, from and after the
time at which the adjusted Warrant Price becomes effective pursuant to
Subsection (b) of this Section by reason of such dividend or subdivision, the
number of shares of Common Stock issuable upon the exercise of each Warrant
shall be increased in proportion to such increase in outstanding shares. In the
event that the number of shares of Common Stock outstanding is decreased by a
combination of the outstanding Common Stock, then, from and after the time at
which the adjusted Warrant Price becomes effective pursuant to this Section 9(b)
by reason of such combination, the number of shares of Common Stock issuable
upon the exercise of each Warrant shall be decreased in proportion to such
decrease in the outstanding shares of Common Stock.
                           (vi) In case of any reorganization or
reclassification of the outstanding Common Stock (other than a change in par
value, or from par value to no par value, or as a result of a subdivision or
combination), or in case of any consolidation of the Company with, or merger of
the Company into, another corporation (other than a consolidation or merger in
which the Company is the continuing corporation and which does not result in any

                                      -14-
<PAGE>

reclassification of the outstanding Common Stock), or in case of any sale or
conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety, the holder of each Warrant then outstanding
shall thereafter have the right to purchase the kind and amount of shares of
Common Stock and other securities and property receivable upon such
reorganization, reclassification, consolidation, merger, sale or conveyance by a
holder of the number of shares of Common Stock which the holder of such Warrant
shall then be entitled to purchase; such adjustments shall apply with respect to
all such changes occurring between the date of this Warrant Agreement and the
date of exercise of such Warrant.
                           (vii) Subject to the provisions of this Section 9, in
case the Company shall, at any time prior to the exercise of the Warrants, make
any distribution of its assets to holders of its Common Stock as a liquidating
or a partial liquidating dividend, then the holder of Warrants who exercises its
Warrants after the record date for the determination of those holders of Common
Stock entitled to such distribution of assets as a liquidating or partial
liquidating dividend shall be entitled to receive for the Warrant Price per
Warrant, in addition to each share of Common Stock, the amount of such
distribution (or, at the option of the Company, a sum equal to the value of any

                                      -15-
<PAGE>

such assets at the time of such distribution as determined by the Board of
Directors of the Company in good faith), which would have been payable to such
holder had he been the holder of record of the Common Stock receivable upon
exercise of its Warrant on the record date for the determination of those
entitled to such distribution.
                           (viii) In case of the dissolution, liquidation or
winding up of the Company, all rights under the Warrants shall terminate on a
date fixed by the Company, such date to be no earlier than ten (10) days prior
to the effectiveness of such dissolution, liquidation or winding up and not
later than five (5) days prior to such effectiveness. Notice of such termination
of purchase rights shall be given to the last registered holder of the Warrants,
as the same shall appear on the books of the Company maintained by the Warrant
Agent, by registered mail at least thirty (30) days prior to such termination
date.
                           (ix) In case the Company shall, at any time prior to
the expiration of the Warrants and prior to the exercise thereof, offer to the
holders of its Common Stock any rights to subscribe for additional shares of any
class of the Company, then the Company shall give written notice thereof to the
last registered holder thereof not less than thirty (30) days prior to the date
on which the books of the Company are closed or a record date is fixed for the
determination of the stockholders entitled to such subscription rights. Such
notice shall specify the date as to which the books shall be closed or record

                                      -16-
<PAGE>

date fixed with respect to such offer of subscription and the right of the
holder thereof to participate in such offer of subscription shall terminate if
the Warrant shall not be exercised on or before the date of such closing of the
books or such record date.
                           (x) Any adjustment pursuant to the aforesaid
provisions of this Section 9 shall be made on the basis of the number of shares
of Common Stock which the holder thereof would have been entitled to acquire by
the exercise of the Warrant immediately prior to the event giving rise to such
adjustment.
                           (xi)  Irrespective of any adjustments in the
Warrant Price or the number or kind of shares purchasable upon exercise of the
Warrants, Warrants previously or thereafter issued may continue to express the
same price and number and kind of shares as are stated in the similar Warrants
initially issuable pursuant to this Warrant Agreement.
                           (xii)  The Company may retain a firm of
independent public accountants (who may be any such firm regularly employed by
the Company) to make any computation required under this Section 9, and any
certificate setting forth such computation signed by such firm shall be
conclusive evidence of the correctness of any computation made under this
Section 9.
                           (xiii)  If at any time, as a result of an
adjustment made pursuant to Section 9(b)(vi) above, the holders of a Warrant or
Warrants shall become entitled to purchase any securities other than shares of
Common Stock, thereafter the number of such securities so purchasable upon
exercise of each Warrant and the Warrant Price for such shares shall be subject

                                      -17-
<PAGE>

to adjustment from time to time in a manner and on terms as nearly equivalent 
as practicable to the provisions with respect to the Common Stock contained in 
Sections 9(b)(ii) through (v).
                  Section 10. Fractional Interest. The Warrants may only be
exercised to purchase full shares of Common Stock and the Company shall not be
required to issue fractions of shares of Common Stock on the exercise of
Warrants. However, if a Warrant holder exercises all Warrants then owned of
record by it and such exercise would result in the issuance of a fractional
share, the Company will pay to such Warrant holder, in lieu of the issuance of
any fractional share otherwise issuable, an amount of cash based on the market
value of the Common Stock of the Company on the last trading day prior to the
exercise date.
                  Section 11.  Notices to Warrantholders.
                           (a) Upon any adjustment of the Warrant Price and the
number of shares of Common Stock issuable upon exercise of a Warrant, then and
in each such case the Company shall give written notice thereof to the Warrant
Agent, which notice shall state the Warrant Price resulting from such adjustment
and the increase or decrease, if any, in the number of shares purchasable at
such price upon the exercise of a Warrant, setting forth in reasonable detail
the method of calculation and the facts upon which such calculation is based.
The Company shall also mail such notice to the holders of the Warrants at their

                                      -18-
<PAGE>

addresses appearing in the Warrant register. Failure to give or mail such
notice, or any defect therein, shall not affect the validity of the adjustments.
                           (b)  In case at any time:
                                    (i)  the Company shall pay dividends payable
in stock upon its Common Stock or make any distribution (other than regular cash
dividends) to the holders of its Common Stock; or
                                    (ii)  the Company shall offer for subscrip-
tion pro rata to the holders of its Common Stock any additional
shares of stock of any class or other rights; or
                                    (iii)  there shall be any capital reorgani-
zation or reclassification of the capital stock of the Company, or consolidation
or merger of the Company with, or sale or substantially all of its assets to,
another corporation; or
                                    (iv)  there shall be a voluntary or involun-
tary dissolution, liquidation or winding up of the Company; then in any one or
more of such cases, the Company shall give written notice in the manner set
forth in Section 11(a) of the date on which (A) a record shall be taken for such
dividend, distribution or subscription rights, or (B) such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up shall take place, as the case may be. Such notice shall also specify
the date as of which the holders of Common Stock of record shall participate in
such dividend, distribution or subscription rights, or shall be entitled to

                                      -19-
<PAGE>

exchange their Common Stock for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up as the case may be. Such notice shall be given at
least thirty (30) days prior to the action in question and not less than thirty
(30) days prior to the record date in respect thereof. Failure to give such
notice, or any defect therein, shall not affect the legality or validity of any
of the matters set forth in this Section 11(b).
                           (c) The Company shall cause copies of all financial
statements and reports, proxy statements and other documents that are sent to
its stockholders to be sent by first-class mail, postage prepaid, on the date of
mailing to such stockholders, to each registered holder of Warrants at his
address appearing in the warrant register as of the record date for the
determination of the stockholders entitled to such documents.
                  Section 12.  Disposition of Proceeds on Exercise of
Warrants.
                           (i)  The Warrant Agent shall promptly forward to
the Company all monies received by the Warrant Agent for the purchase of shares
of Common Stock through the exercise of such Warrants.
                (ii) The Warrant Agent shall keep copies of this
Agreement available for inspection by holders of Warrants during normal business
hours.

                  Section 13. Redemption of Warrants. The Warrants are
redeemable by the Company upon the consent of the Underwriter, in whole or in
part, on not less than thirty (30) days' prior written notice at a redemption
price of $.10 per Warrant at any time commencing _________, 1998; provided that
(i) the closing sale price of the Common Stock on all thirty (30) trading days
ending on the third day prior to the day on which the Company gives notice of
redemption has been at least 150% of the then effective exercise price of the
Warrants (the "Target Redemption Price") and ii) the Warrants are currently
exercisable]. The redemption notice shall be mailed to the holders of the
Warrants at their addresses appearing in the Warrant register. Holders of the
Warrants will have exercise rights until the close of business on the date fixed
for redemption.
                  Section 14. Merger or Consolidation or Change of Name of
Warrant Agent. Any corporation or company which may succeed to the corporate
trust business of the Warrant Agent by any merger or consolidation or otherwise
shall be the successor to the Warrant Agent hereunder without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
provided that such corporation would be eligible to serve as a successor Warrant
Agent under the provisions of Section 16 of this Agreement. In case at the time
such successor to the Warrant Agent shall succeed to the agency created by this

                                      -21-

Agreement, any of the Warrants shall have been countersigned but not delivered,
any such successor to the Warrant Agent may adopt the countersignature of the
original Warrant Agent and deliver such Warrants so countersigned.
                  In case at any time the name of the Warrant Agent shall be
changed and at such time any of the Warrants shall have been countersigned but
not delivered, the Warrant Agent may adopt the countersignature under its prior
name and deliver Warrants so countersigned. In all such cases such Warrants
shall have the full force provided in the Warrants and in the Agreement.
                  Section 15. Duties of Warrant Agent. The Warrant Agent
undertakes the duties and obligations imposed by this Agreement upon the
following terms and conditions, by all of which the Company and the holders of
Warrants, by their acceptance thereof, shall be bound:
                (a) The statements of fact and recitals contained
herein and in the Warrants shall be taken as statements of the Company, and the
Warrant Agent assumes no responsibility for the correctness of any of the same

The Warrant Agent assumes no responsibility with respect to the distribution of
the Warrants except as herein expressly provided.
                (b) The Warrant Agent shall not be responsible for any failure
of the Company to comply with any of the covenants in this Agreement or in the
Warrants to be complied with by the Company.

satisfactory to it (who may be counsel for the Company) and the Warrant Agent
shall incur no liability or responsibility to the Company or to any holder of
any Warrant in respect of any action taken, suffered or omitted by it hereunder
in good faith and in accordance with the opinion or the advice of such counsel.
                (d) The Warrant Agent shall incur no liability or
responsibility to the Company or to any holder of any Warrant for any action
taken in reliance on any notice, resolution, waiver, consent, order, certificate
or other instrument believed by it to be genuine and to have been signed, sent
or presented by the proper party or parties.
                (e) The Company agrees to pay to the Warrant Agent reasonable
compensation for all services rendered by the Warrant Agent in the execution of
this Agreement, to reimburse the Warrant Agent for all expenses, taxes and
governmental charges and other charges incurred by the Warrant Agent in the
execution of this Agreement and to indemnify the Warrant Agent and save it

reasonable counsel fees, for anything done or omitted by the Warrant Agent in
the execution of this Agreement except as a result of the Warrant Agent's
negligence, willful misconduct or bad faith.

                (f) The Warrant Agent shall be under no obligation to
institute any action, suit or legal proceeding or to take any other action
likely to involve expenses unless the Company or one or more registered holders
of Warrants shall furnish the Warrant Agent with reasonable security and
indemnity for any costs and expenses which may be incurred, but this provision
shall not affect the power of the Warrant Agent to take such action as the
Warrant Agent may consider proper, whether with or without any such security or
indemnity. All rights of action under this Agreement or under any of the
Warrants may be enforced by the Warrant Agent without the possession of any of
the Warrants or the production thereof at any trial or other proceeding, and any
such action, suit or proceeding instituted by the Warrant Agent shall be brought
in its name as Warrant Agent, and any recovery of judgment shall be for the
ratable benefit of the registered holders of the Warrants, as their respective
rights and interests may appear.
                (g) The Warrant Agent and any stockholder, director, officer,
partner or employee of the Warrant Agent may buy, sell or deal in any of the
Warrants or other securities of the Company or become pecuniarily interested in
any transaction in which the Company may be interested, or contract with or lend
money to or otherwise act as fully and freely as though it were not the Warrant

Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from
acting in any other capacity for the Company or for any other legal entity.
                (h) The Warrant Agent shall act hereunder solely as agent and 
its duties shall be determined solely by the provisions hereof.
                (i) The Warrant Agent may execute and exercise any of the rights
or powers hereby vested in it or perform any duty hereunder either itself or by
or through its attorneys, agents or employees, and the Warrant Agent shall not
be answerable or accountable for any such attorneys, agents or employees or for
any loss to the Company resulting from such neglect or misconduct, provided
reasonable care had been exercised in the selection and continued employment
thereof.
                (j) Any request, direction, election, order or demand of the
Company shall be sufficiently evidenced by an instrument signed in the name of
the Company by its Chief Executive Officer, President or a Vice President or its
Secretary or an Assistant Secretary or its Treasurer or an Assistant Treasurer
(unless other evidence in respect thereof be herein specifically prescribed);
and any resolution of the Board of Directors may be evidenced to the Warrant
Agent by a copy thereof certified by the Secretary or an Assistant Secretary of
the Company.

                  Section 16.  Change of Warrant Agent.  The Warrant
Agent may resign and be discharged from its duties under this Agreement by

                                      -25-


<PAGE>



giving to the Company notice in writing, and to the holders of the Warrants
notice by mailing such notice to the holders at their addresses appearing on the
Warrant register, of such resignation, specifying a date when such resignation
shall take effect. The Warrant Agent may be removed by like notice to the
Warrant Agent from the Company and the like mailing of notice to the holders of
the Warrants. If the Warrant Agent shall resign or be removed or shall otherwise
become incapable of acting, the Company shall appoint a successor to the Warrant
Agent. If the Company shall fail to make such appointment within a period of
thirty (30) days after such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Warrant Agent
or after the Company has received such notice from a registered holder of a
Warrant (who shall, with such notice, submit his Warrant for inspection by the
Company), then the registered holder of any Warrant may apply to any court of
competent jurisdiction for the appointment of a successor to the Warrant Agent.
Any successor Warrant Agent, whether appointed by the Company or by such a
court, shall be a bank or trust company, in good standing, incorporated under
New York or federal law. After appointment, the successor Warrant Agent shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Warrant Agent without further act or deed and the
former Warrant Agent shall deliver and transfer to the successor Warrant Agent
all cancelled Warrants, records and property at the time held by it hereunder,
and execute and deliver any further assurance or conveyance necessary for the
purpose. Failure to file or mail any notice provided for in this Section,
however, or any defect therein, shall not affect the validity of the resignation
or removal of the Warrant Agent or the appointment of the successor Warrant
Agent, as the case may be.

Company's Common Stock issuable upon the exercise of the rights of purchase

   Re: HealthDesk Corporation, Registration Statement on Form SB-2 

Ladies and Gentlemen: 

   
   As counsel to HealthDesk Corporation (the "Company"), we are rendering 
this opinion in connection with a proposed sale of those certain shares of 
the Company's newly-issued Common Stock and those certain warrants 
exercisable for shares of the Company's newly-issued Common Stock as set 
forth in the Registration Statement on Form SB-2 to which this opinion is 
being filed as Exhibit 5.1 (collectively, the "Shares"). We have examined all 
instruments, documents and records which we deemed relevant and necessary for 
the basis of our opinion hereinafter expressed. In such examination, we have 
assumed the genuineness of all signatures and the authenticity of all 
documents submitted to us as originals and the conformity to the originals of 
all documents submitted to us as copies. 

   We express no opinion with respect to (i) the availability of equitable 
remedies, including specific performance, or (ii) the effect of bankruptcy, 
insolvency, reorganization, moratorium or equitable principles relating to or 
limiting creditors' rights generally. 

   Based on such examination, we are of the opinion that the Shares 
identified in the above-referenced Registration Statement will be, upon 
effectiveness of the Registration Statement and receipt by the Company of 
payment therefor, validly authorized, legally issued, fully paid, and 
nonassessable. 

   We hereby consent to the filing of this opinion as an exhibit to the 
above-referenced Registration Statement and to the use of our name wherever 
it appears in said Registration Statement, including the Prospectus 
constituting a part thereof, as originally filed or as subsequently amended. 

                                            Respectfully submitted, 

                                            GRAY CARY WARE & FREIDENRICH

provided in Article 13 hereof, the Shares and the Underlying Warrants are in all
respects identical to the Public Shares and Public Warrants being sold to the
public pursuant to the terms and provisions of the Underwriting Agreement.

         2. Warrant Certificates.

The warrant certificates delivered and to be delivered pursuant to this
Agreement (the "Warrant Certificates") shall be, for the Warrants exercisable

attached hereto and made a part hereof, and, for the Warrants exercisable for
the purchase of Underlying Warrants, in the form of Exhibit B attached hereto

        3. Exercise of Warrant.

Warrant Certificate ("Holder" or "Holders") shall be entitled to receive a

<PAGE>
   

   

           3.2. Cashless Exercise. At any time during the Warrant Exercise Term,
the Holder may, at the Holder's option, exchange, in whole or in part, the
Warrants represented by such Holder's Warrant Certificate which are exercisable
for the purchase of Shares (a "Warrant Exchange"), into the number of Shares and
Underlying Warrants determined in accordance with this Section 3.2, by
surrendering such Warrant Certificate at the principal office of the Company or
at the office of its transfer agent, accompanied by a notice stating such
Holder's intent to effect such exchange, the number of Warrants to be so
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "Notice of Exchange"). The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "Exchange Date"). Certificates for the
Shares issuable upon such Warrant Exchange and, if applicable, a new Warrant
Certificate of like tenor representing the Warrants which were subject to the
surrendered Warrant Certificate and not included in the Warrant Exchange, shall
be issued as of the Exchange Date and delivered to the Holder within three (3)
business days following the Exchange Date. In connection with any Warrant
Exchange, the Holder shall be entitled to subscribe for and acquire (i) the
number of Shares (rounded to the next highest integer) which would, but for such
Warrant Exchange, than be issuable pursuant to the provisions of Section 3.1
above upon the exercise of the Warrants specified by the Holder in its Notice of
Exchange (the "Total Share Number") less (ii) the number of Shares equal to the
quotient obtained by dividing (a) the product of the Total Share Number and the
existing Exercise Price per Share (as hereinafter defined) by (b) the Fair
Market Price (as hereinafter defined) of a Public Share on the day preceding the
Warrant Exchange. "Fair Market Price" at any date shall be deemed to be the last
reported sale price, or, in case no such reported sales takes place on such day,
the average of the last reported sale prices for the last five (5) trading days,
in either case as officially reported by the principal securities exchange on
which the Common Stock is listed or admitted to trading or as reported in the
NASDAQ National Market System, or, if the Common Stock is not listed or admitted
to trading on any national securities exchange or quoted on the NASDAQ National
Market System, the average of the last reported closing bid price as furnished
by (i) the National Association of Securities Dealers, Inc. through NASDAQ or
(ii) a similar organization if NASDAQ is no longer reporting such information in
either case averaged over the five (5) trading days preceding the Warrant
Exchange.
 
           4. Issuance of Certificates.

           Upon the exercise of the Warrants, the issuance of certificates for
the Shares purchased and certificates for the Underlying Warrants purchased, and
upon the exercise of the Underlying Warrants, the issuance of certificates for
the Underlying Warrant Shares purchased, shall be made forthwith (and in any
event within three (3) business days thereafter) without charge to the Holder
thereof including, without limitation, any tax which may be payable in respect
of the issuance thereof, and such certificates shall (subject to the provisions
of Article 5 hereof) be issued in the name of, or in such names as may be
directed by, the Holder thereof; provided, however, that the Company shall not
be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of any such certificates in a name other
than that of the Holder and the Company shall not be required to issue or
deliver such certificates unless or until the person or persons requesting the
issuance thereof shall have paid to the Company the amount of such tax or shall

           securities issuable upon exercise thereof have not been registered
           for purposes of public distribution under the Securities Act of 1933,
           as amended (the "Act"), and may not be offered or sold except (i)
           pursuant to an effective registration statement under the Act, (ii)
           to the extent applicable, pursuant to Rule 144 under the Act (or any
           similar rule under such Act relating to the disposition of
           securities), or (iii) upon the delivery by the holder to the Company
           of an opinion of counsel, reasonably satisfactory to counsel to the
           Company, stating that an exemption from registration under such Act
           is available."

           5. Restriction on Transfer of Warrants.
                  
           The Holder, by the Holder's acceptance thereof, covenants and agrees
that the Warrants are being acquired as an investment and not with a view to the
distribution thereof, and that the Warrants may not be sold, transferred,
assigned, hypothecated or otherwise disposed of, in whole or in part, for a
period of one (1) year from the date hereof, except to the Underwriter or to the
Designees. Any such transfer, assignment, hypothecation or other disposition
shall be in a manner which complies with applicable state and federal securities
laws and regulations.

price of each Warrant shall be $6.60 per Share and $.132 per Underlying Warrant.
The adjusted exercise price per Share and the adjusted exercise price per
Underlying Warrant shall be the prices which shall result from time to time from
any and all adjustments of the initial exercise price per Share or per
Underlying Warrant, as the case may be, in accordance with the provisions of
Article 8 hereof.

    
                                      -4-
<PAGE>

              6.2. Exercise Price. The term "Exercise Price" herein shall mean
the initial exercise price or the adjusted exercise price, depending upon the
context.
              
           7. Registration Rights.
   

              7.1. Registration Under the Securities Act of 1933. None of the
Warrants, the Shares, the Underlying Warrants, or the Underlying Warrant Shares
have been registered for purposes of public distribution under the Securities
Act of 1933, as amended (the "Act").

              7.2. Registrable Securities. As used herein the term "Registrable
Security" means each of the Warrants, the Shares, the Underlying Warrants, the
Underlying Warrant Shares and any shares of Common Stock issued upon any stock
split or stock dividend in respect of such Shares or Underlying Warrant Shares;
provided, however, that with respect to any particular Registrable Security,
such security shall cease to be a Registrable Security when, as of the date of
determination, (i) it has been effectively registered under the Act and disposed
of pursuant thereto, (ii) registration under the Act is no longer required for
subsequent public distribution of such security, or (iii) it has ceased to be
outstanding. The term "Registrable Securities" means any and/or all of the
securities falling within the foregoing definition of a "Registrable Security."
In the event of any merger, reorganization, consolidation, recapitalization or
other change in corporate structure affecting the Common Stock, such adjustment
shall be made in the definition of "Registrable Security" as is appropriate in
order to prevent any dilution or enlargement of the rights granted pursuant to
this Article 7.

              7.3. Piggyback Registration. If (but without any obligation of the
Company to do so), at any time during the seven years following the effective
date of the Public Offering, the Company proposes to prepare and file one or
more post-effective amendments to the registration statement filed in connection
with the Public Offering or any new registration statement or post-effective
amendments thereto covering equity or debt securities of the Company, or any
such securities of the Company held by its shareholders (in any such case, other
than in connection with a registration relating solely to a transaction pursuant
to Rule 145 or a registration relating to employee benefit plans on Form S-8 or
successor form) (for purposes of this Article 7, collectively, the "Registration
Statement"), it will give written notice of its intention to do so by registered
mail ("Notice"), at least thirty (30) days prior to the filing of each such
Registration Statement, to all holders of the Registrable Securities. Upon the
written request of such a holder (a "Requesting Holder"), made within twenty
(20) days after receipt of the Notice, that the Company include any of the
Requesting Holder's Registrable Securities in the proposed Registration
Statement, the Company shall, as to each such Requesting Holder, use its best
efforts to effect the registration under the Act of the Registrable Securities
which it has been so requested to register ("Piggyback Registration"), at the
Company's sole cost and expense and at no cost or expense to the Requesting
Holders (except as provided in Section 7.5(b) hereof). Notwithstanding the
provisions of this Section 7.3, the Company shall have the right at any time
after it shall have given written notice pursuant to this Section 7.3
(irrespective of whether any written request for inclusion of Registrable
Securities shall have already been made by a Requesting Holder or received by
the Company) to elect not to file any such proposed Registration Statement, or
to withdraw the same after the filing but prior to the effective date thereof.

              7.4. Demand Registration. 
   

                   (a) At any time during the Warrant Exercise Term, any
"Majority Holder" (as such term is defined in Section 7.4(d) below) of the
Registrable Securities shall have the right (which right is in addition to the
piggyback registration rights provided for under Section 7.3 hereof),
exercisable by written notice to the Company (the "Demand Registration
Request"), to have the Company prepare and file with the Commission on one
occasion, at the sole expense of the Company (except as provided in Section
7.5(b) hereof), a Registration Statement and such other documents, including a
prospectus, as may be necessary (in the opinion of both counsel for the Company
and counsel for such Majority Holder) in order to comply with the provisions of
the Act, so as to permit a public offering and sale of the Registrable
Securities by the holders thereof; provided that the Company shall not be
obligated to effect any such registration if the Company shall furnish to the
Majority Holder a certificate signed by the President of the Company stating
that in the good faith judgment of the Board of Directors of the Company, it is
currently entering into a transaction for which a Form 8-K, including financial
statements, will need to be filed with the Commission, in which event the
Company shall have the right to defer the filing of the registrations statement
for a period of not more than ninety (90) days after receipt of the request of
the Majority Holder under this Section 7.4(a). The Company shall use its best
efforts to cause the Registration Statement to become effective under the Act,
so as to permit a public offering and sale of the Registrable Securities by the
holders thereof. Once effective, the Company will use its best efforts to
maintain the effectiveness of the Registration Statement until the earlier of
(i) the date that all of the Registrable Securities have been sold or (ii) the
date the holders thereof receive an opinion of counsel to the Company that all
of the Registrable Securities may be freely traded without registration under
the Act, under Rule 144(k) promulgated under the Act or otherwise.

                   (b) The Company covenants and agrees to give written notice
of any Demand Registration Request to all holders of the Registrable Securities
within ten (10) days from the date of the Company's receipt of any such Demand
Registration Request. After receiving notice from the Company as provided in
this Section 7.4(b), holders of Registrable Securities may request the Company
to include their Registrable Securities in the Registration Statement to be
filed pursuant to Section 7.4(a) hereof by notifying the Company of their
decision to have such securities included within ten (10) days of their receipt
of the Company's notice.

                   (c) The term "Majority Holder" as used in Section 7.4 hereof
shall mean any holder or any combination of holders of Registrable Securities,
if included in such holders' Registrable Securities are that aggregate number of
shares of Common Stock (including Shares already issued, Shares issuable
pursuant to the exercise of outstanding Warrants, Underlying Warrant Shares
already issued and Underlying Warrant Shares issuable pursuant to the exercise
of outstanding Underlying Warrants) as would constitute a majority of the
aggregate number of shares of Common Stock (including Shares already issued,
Shares issuable pursuant to the exercise of outstanding Warrants, Underlying
Warrant Shares already issued and Underlying Warrant Shares issuable pursuant to
the exercise of outstanding Underlying Warrants) included in all the Registrable
Securities.
    

              7.5. Covenants of the Company With Respect to Registration.  The 
Company covenants and agrees as follows:
   
                    (a) In connection with any registration under Section 7.4
hereof, the Company shall file the Registration Statement as expeditiously as
possible, but in any event no later than thirty (30) days following receipt of
any demand therefor, shall use its best efforts to have any such Registration
Statement declared effective at the earliest possible time, and shall furnish
each Holder such number of prospectuses as shall reasonably be requested.

                   (b) The Company shall pay all costs, fees and expenses (other
than underwriting fees, discounts and nonaccountable expense allowance
applicable to the Registrable Securities and fees and expenses of counsel
retained by the Holders) in connection with all Registration Statements filed
pursuant to Sections 7.3 and 7.4(a) hereof including, without limitation, the
Company's legal and accounting fees, printing expenses, and blue sky fees and
expenses.
    
                   (c) The Company will take all necessary action which may be
required in qualifying or registering the Registrable Securities included in the
Registration Statement, for offering and sale under the securities or blue sky
laws of such states as are reasonably requested by the holders of such
securities.
   
                   (d) The Company shall indemnify any holder of the Registrable
Securities to be sold pursuant to any Registration Statement and any underwriter
or person deemed to be an underwriter under the Act and each person, if any, who
controls such Holder or underwriter or person deemed to be an underwriter within
the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange
Act of 1934, as amended ("Exchange Act"), against all loss, claim, damage,
expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which any
of them may become subject under the Act, the Exchange Act or otherwise, arising
from such Registration Statement to the same extent and with the same effect as
the provisions pursuant to which the Company has agreed to indemnify the
Underwriter as set forth in Section 7 of the Underwriting Agreement and to
provide for just and equitable contribution as set forth in Section 8 of the
Underwriting Agreement.

                   (e) Any Holder of Registrable Securities to be sold pursuant
to a Registration Statement, and such Holder's successors and assigns, shall
severally, and not jointly, indemnify, the Company, its officers and directors
and each person, if any, who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim,
damage or expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holder, or such Holder's
successors or assigns, for inclusion in such Registration Statement to the same
extent and with the same effect as the provisions pursuant to which the
Underwriter has agreed to indemnify the Company as set forth in Section 7 of the
Underwriting Agreement and to provide for just and equitable contribution as set
forth in Section 8 of the Underwriting Agreement.

                   (f) Nothing contained in this Agreement shall be construed as
requiring any holder to exercise the Warrants or the Underlying Warrants held by
such Holder prior to the initial filing of any registration statement or the
effectiveness thereof.

                   (g) The Company shall not permit the inclusion of any
securities other than the Registrable Securities to be included in any
Registration Statement filed pursuant to Section 7.4 hereof, without the prior
written consent of the Majority Holders, which consent shall not be unreasonably
withheld.
       
                   (h) The Company shall promptly deliver copies of all
correspondence between the Commission and the Company, its counsel or auditors
and all memoranda relating to discussions with the Commission or its staff with
respect to the Registration Statement to each Holder of Registrable Securities
included for such registration in such Registration Statement pursuant to
Section 7.3 or Section 7.4 hereof that requests such correspondence and
memoranda and to the managing underwriter, if any, of the offering in connection
with which such Holder's Registrable Securities are being registered and shall
permit each Holder of Registrable Securities and such underwriter to do such
reasonable investigation, upon reasonable advance notice, with respect to
information contained in or omitted from the Registration Statement as it deems
reasonably necessary to comply with applicable securities laws or rules of the
National Association of Securities Dealers, Inc. Such investigation shall
include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times as any such Holder or underwriter
shall reasonably request.

           8. Adjustments of Exercise Price and Number of Securities. The
following adjustments apply to the Exercise Price of the Warrants with respect
to the Shares and the number of Shares purchasable upon exercise of the
Warrants. In the event the Exercise Price per Share and/or the number of Shares
so purchasable is adjusted, then the Exercise Price of the Warrants relating to
the Underlying Warrants and the number of underlying Warrants purchasable
hereunder shall be adjusted in the same proportion.
    
              
              8.1. Computation of Adjusted Price. In case the Company shall at
any time after the date hereof pay a dividend in shares of Common Stock or make
a distribution in shares of Common Stock, then upon such dividend or
distribution, the Exercise Price in effect immediately prior to such dividend or
distribution shall forthwith be reduced to a price determined by dividing:

                   (a) an amount equal to the total number of shares of Common
Stock outstanding immediately prior to such dividend or distribution multiplied
by the Exercise Price in effect immediately prior to such dividend or
distribution, by

                   (b) the total number of shares of Common Stock outstanding
immediately after such issuance or sale.
   

                   For the purposes of any computation to be made in accordance
with the provisions of this Section 8.1, the Common Stock issuable by way of
dividend or other distribution on any stock of the Company shall be deemed to
have been issued immediately after the opening of business on the date following
the date fixed for the determination of shareholders entitled to receive such
dividend or other distribution.
    

              8.2. Subdivision and Combination. In case the Company shall at any
time subdivide or combine the outstanding shares of Common Stock, the Exercise
Price shall forthwith be proportionately decreased in the case of subdivision or
increased in the case of combination.
   
              8.3. Adjustment in Number of Securities. Upon each adjustment of
the Exercise Price pursuant to the provisions of this Article 8, the number of
Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full number by multiplying a number equal to the Exercise Price in
effect immediately prior to such adjustment by the number of Shares issuable
upon exercise of the Warrants immediately prior to such adjustment and dividing
the product so obtained by the Exercise Price, adjusted as provided for in
Sections 8.1 and 8.2 hereof, provided, however, that if an event occurs that
results in an adjustment of the number and/or price of the shares of Common
Stock issuable upon exercise of the Public Warrants pursuant to Section 9 of the
Warrant Agreement by and among the Company, the Underwriter and American Stock
Transfer and Trust Company dated as of ___________, 1997 ("Public Warrant
Agreement"), resulting in automatic adjustment in the number and/or price of the
Underlying Warrant Shares issuable upon exercise of the Underlying Warrants
pursuant to Section 8.5 hereof, then the adjustment provided for in this Section
8.3 shall not, in such instance, result in any further adjustment in the
aggregate number of shares of Common Stock ultimately issuable upon exercise of
the Underlying Warrants.

              8.4. Reclassification, Consolidation, Merger, etc. In case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation
of the Company with, or merger of the Company into, another corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or a change in par value, as aforesaid), or in the
case of a sale or conveyance to another corporation of the property of the
Company as an entirety, the Holders shall thereafter have the right to purchase
the kind and number of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance as if the Holders were the owners of both the Shares and the
Underlying Warrant Shares immediately prior to any such events, at a price equal
to the product of (x) the number of shares of Common Stock issuable upon
exercise of the Holders' Warrants and the Underlying Warrants and (y) the
exercise prices for the Warrants and the Underlying Warrants in effect
immediately prior to the record date for such reclassification, change,
consolidation, merger, sale or conveyance as if such Holders had exercised the
Warrants and the Underlying Warrants.

              8.5. Determination of Outstanding Common Shares. The number of
Common Shares at any one time outstanding shall include the aggregate number of
shares issued and the aggregate number of shares issuable upon the exercise of
options, rights, warrants and upon the conversion or exchange of convertible or
exchangeable securities.

              8.6. Adjustment of Underlying Warrants' Exercise Price and
Securities Issuable Upon Exercise of Underlying Warrants. With respect to any of
the Underlying Warrants, whether or not the Warrants have been exercised and
whether or not the Warrants are issued and outstanding, the exercise price for,
and the number of, Underlying Warrant Shares issuable upon exercise of the
Underlying Warrants shall be automatically adjusted in accordance with Section 9
of the Public Warrant Agreement, upon the occurrence of any of the events
described therein. Thereafter, until the next such adjustment or until otherwise
adjusted in accordance with this Section 8, the Underlying Warrants shall be
exercisable at such adjusted exercise price and for such adjusted number of
Underlying Warrant Shares.

<PAGE>

   
              8.7. Dividends and Other Distributions with Respect to Outstanding
Securities. In the event that the Company shall at any time prior to the
exercise of all Warrants make any distribution of its assets to holders of its
Common Stock as a liquidating or a partial liquidating dividend, then the holder
of Warrants who exercises its Warrants after the record date for the
determination of those holders of Common Stock entitled to such distribution of
assets as a liquidating or partial liquidating dividend shall be entitled to
receive for the Exercise Price per Warrant, in addition to each share of Common
Stock, the amount of such distribution (or, at the option of the Company, a sum
equal to the value of any such assets at the time of such distribution as
determined by the Board of Directors of the Company in good faith) which would
have been payable to such holder had he been the holder of record of the Common
Stock receivable upon exercise of his Warrant on the record date for the
determination of those entitled to such distribution. At the time of any such
dividend or distribution, the Company shall make appropriate reserves to ensure
the timely performance of the provisions of this Subsection 8.7.


              8.8. Subscription Rights for Shares of Common Stock or Other
Securities. In the case that the Company or an affiliate of the Company shall at
any time after the date hereof and prior to the exercise of all the Warrants
issue any rights, warrants or options to subscribe for shares of Common Stock or
any other securities of the Company or of such affiliate to all the shareholders
of the Company, the Holders of unexercised Warrants on the record date set by
the Company or such affiliate in connection with such issuance of rights,
warrants or options shall be entitled, in addition to the shares of Common Stock
or other securities receivable upon the exercise of the Warrants, to receive
such rights, warrants or options shall be entitled, in addition to the shares of
Common Stock or other securities receivable upon the exercise of the Warrants,
to receive such rights at the time such rights, warrants or options that such
Holders would have been entitled to receive had they been, on such record date,
the holders of record of the number of whole shares of Common Stock then
issuable upon exercise of their outstanding Warrants (assuming for purposes of
this Section 8.8), that the exercise of the Warrants is permissible immediately
upon issuance).

           9. Exchange and Replacement of Warrant Certificates.

           Each Warrant Certificate is exchangeable without expense, upon the
surrender thereof by the Holder at the principal executive office of the
Company, for a new Warrant Certificate of like tenor and date representing in
the aggregate the right to purchase the same number of securities in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.
    

           Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrant
Certificate, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

<PAGE>

           10. Elimination of Fractional Interests.
   
           The Company shall not be required to issue certificates representing
fractions of Shares or fractions of Underlying Warrants upon the exercise of the
Warrants, nor shall it be required to issue scrip or pay cash in lieu of
fractional interests, it being the intent of the parties that all fractional
interests shall be eliminated by rounding any fraction up to the nearest whole
number of Shares and Underlying Warrants.

           11. Reservation and Listing of Securities.

           The Company shall, during the period the Warrants are exercisable,
reserve and keep available out of its authorized shares of Common Stock, solely
for the purpose of issuance upon the exercise of the Warrants and the Underlying
Warrants, such number of shares of Common Stock as shall be issuable upon the
exercise thereof. The Company covenants and agrees that, upon exercise of the
Warrants and assuming receipt of the payment of the Exercise Price therefor, all
Shares issuable upon such exercise shall be duly and validly issued, fully paid,
non-assessable and not subject to the preemptive rights of any shareholder. The
Company further covenants and agrees that upon exercise of the Underlying
Warrants and payment of the respective Underlying Warrant exercise price
therefor, all Underlying Warrant Shares issuable upon such exercise shall be
duly and validly issued, fully paid, non-assessable and not subject to the
preemptive rights of any shareholder. As long as the Warrants shall be
outstanding, the Company shall use its best efforts to cause all shares of
Common Stock issuable upon the exercise of the Warrants and the Underlying
Warrants and all Underlying Warrants to be listed on or quoted by NASDAQ or
listed on such national securities exchange, in the event the Common Stock is
listed on a national securities exchange. 
    

           12. Notices to Warrant Holders.

           Nothing contained in this Agreement shall be construed as conferring
upon the Holder or Holders the right to vote or to consent or to receive notice
as a shareholder in respect of any meetings of shareholders for the election of
directors or any other matter, or as having any rights whatsoever as a
shareholder of the Company. If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

                (a) the Company shall take a record of the holders of its shares
           of Common Stock for the purpose of entitling them to receive a
           dividend or distribution payable otherwise than in cash, or a cash
           dividend or distribution payable otherwise than out of current or
           retained earnings, as indicated by the accounting treatment of such
           dividend or distribution on the books of the Company; or

                                      -12-
    
<PAGE>



                (b) the Company shall offer to all the holders of its Common
           Stock any additional shares of capital stock of the Company or
           securities convertible into or exchangeable for shares of capital
           stock of the Company, or any option, right or warrant to subscribe
           therefor; or
   
                (c) a dissolution, liquidation or winding up of the Company
           (other than in connection with a consolidation or merger) or a sale
           of all or substantially all of its property, assets and business as
           an entirety shall be proposed; or
             
                (d) reclassification or change of the outstanding shares of
           Common Stock (other than a change in par value to no par value, or
           from no par value to par value, or as a result of a subdivision or
           combination), consolidation of the Company with, or merger of the
           Company into, another corporation (other than a consolidation or
           merger in which the Company is the surviving corporation and which
           does not result in any reclassification or change of the outstanding
           shares of Common Stock, except a change as a result of a subdivision
           or combination of such shares or a change in par value, as
           aforesaid), or a sale or conveyance to another corporation of the
           property of the Company as an entirety is proposed; or

                (e) The Company or an affiliate of the Company shall propose to
           issue any rights to subscribe for shares of Common Stock or any other
           securities of the Company or of such affiliate to all the
           shareholders of the Company;

then, in any one or more of said events, the Company shall give written notice
to the Holder or Holders of such event at least fifteen (15) days prior to the
date fixed as a record date or the date of closing the transfer books for the
determination of the shareholders entitled to such dividend, distribution,
convertible or exchangeable securities or subscription rights, options or
warrants, or entitled to vote on such proposed dissolution, liquidation, winding
up or sale. Such notice shall specify such record date or the date of closing
the transfer books, as the case may be. Failure to give such notice or any
defect therein shall not affect the validity of any action taken in connection
with the declaration or payment of any such dividend or distribution, or the
issuance of any convertible or exchangeable securities or subscription rights,
options or warrants, or any proposed dissolution, liquidation, winding up or
sale.

           13.  Underlying Warrants.
           
           The form of the certificates representing the Underlying Warrants
(and the form of election to purchase shares of Common Stock upon the exercise
of the Underlying Warrants and the form of assignment printed on the reverse
thereof) shall be substantially as set forth in Exhibit "A" to the Public
Warrant Agreement; provided, however, (i) each Underlying Warrant issuable upon
exercise of the Warrants shall evidence the right to initially purchase 180,000
fully paid and non-assessable share(s) of Common Stock in respect of the
Underlying Warrant at an initial purchase price of $8.25 per share until
__________, 2002 and (ii) the Target Redemption Price (as defined in the Public
Warrant Agreement) of the Underlying Warrants is 150% of the then effective
exercise price of the Underlying Warrants. As set forth in Section 8.5 of this
Agreement, the exercise price of the Underlying Warrants and the number of
shares of Common Stock issuable upon the exercise of the Underlying Warrants are
subject to adjustment, whether or not the Warrants have been exercised and the
Underlying Warrants have been issued, in the manner and upon the occurrence of
the events set forth in Section 9 of the Public Warrant Agreement, which is
hereby incorporated herein by reference and made a part hereof as if set forth
in its entirety herein. Subject to the provisions of this Agreement and upon
issuance of the Underlying Warrants, each registered holder of such Underlying
Warrants shall have the right to purchase from the Company (and the Company
shall issue to such registered holders) up to the number of fully paid and
non-assessable Underlying Warrant Shares (subject to adjustment as provided
herein and in the Public Warrant Agreement), free and clear of all preemptive
rights of shareholders, provided that such registered holder complies, in
connection with the exercise of such holders' Underlying Warrants, with the
terms governing exercise of the Public Warrants set forth in the Public Warrant
Agreement, and pays the applicable exercise price, determined in accordance with
the terms of the Public Warrant Agreement. Upon exercise of the Underlying
Warrants, the Company shall forthwith issue to the registered holder of any such
Underlying Warrants, in such holder's name or in such name as may be directed by
such holder, certificates for the number of Underlying Warrant Shares so
purchased. The Underlying Warrants shall be transferable in the manner provided
in the Public Warrant Agreement, and upon any such transfer, a new Underlying
Warrant shall be issued promptly to the transferee. The Company covenants to,
and agrees with, each Holder that without the prior written consent of all the
Holders, the Public Warrant Agreement will not be modified, amended, cancelled,
altered or superseded, and that the Company will send to each Holder,
irrespective of whether or not the Warrants have been exercised, any and all
notices required by the Public Warrant Agreement to be sent to holders of the
Public Warrants.

           14. Notices.

           All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made when
delivered, or mailed by registered or certified mail, return receipt requested:

                (a) If to a Holder, to the address of such Holder as shown on
           the books of the Company; or

                (b) If to the Company, to the address set forth in Section 3 of
           this Agreement or to such other address as the Company may designate
           by notice to the Holders.

           15. Supplements and Amendments.
   
               The Company and the Underwriter may from time to time
supplement or amend this Agreement without the approval of any Holders of the
Warrants and/or Warrant Securities in order to cure any ambiguity, to correct or
supplement any provision contained herein which may be defective or inconsistent
with any provisions herein, or to make any other provisions in regard to matters
or questions arising hereunder which the Company and the Underwriter may deem
necessary or desirable and which the Company and the Underwriter deem not to
adversely affect the interests of the Holders of Warrant Certificates.
