                                  THE COMPANY
 
    Advanced Health Corporation provides a full range of integrated management
services and clinical information systems to physician group practices, single
legal entities comprised of multiple physicians, and to physician networks,
aggregations of individual physicians and physician groups formed for the
purpose of entering into contracts with third-party payors. The management
services provided by the Company include physician practice and network
development, marketing, payor contracting, financial and administrative
management, clinical information management, human resource management and
practice and network governance. The Company developed its clinical information
systems to provide physicians, at the point of care and on a real-time basis,
with patient-specific clinical and payor information and the ability to generate
patient medical orders and facilitate the implementation of disease management
programs. Through the management of multi-specialty and single-specialty
physician group practices and networks, the Company focuses its management
efforts on high-cost, high-volume disease specialties, such as cardiology,
oncology and orthopedics. The Company currently manages two multi-specialty
physician group practices and two single-specialty physician group practices
comprised of more than 75 physicians in the New York metropolitan area and eight
physician networks with approximately 800 physicians in the greater New York and
Atlanta metropolitan areas, and provides physician group consulting services to
more than 100 physicians.
 
    Health care expenditures in the U.S. totalled approximately $1 trillion in
1994, with approximately 85% of such expenditures controlled by physician
decisions. Increasing concern over the rising cost of health care has led to the
development of managed care programs, which have shifted traditional fee-
for-service reimbursement for physicians to capitated and other fixed-fee
arrangements. As the financial risk of delivering health care shifts from payors
to providers, physicians are faced with increasing management responsibilities
and declining compensation. Because the majority of physicians practice
individually or in two-person groups, they tend to have limited financial and
administrative capacity. Consequently, physician practice management companies
have emerged in recent years to manage the financial and administrative
requirements of physician organizations. More importantly, the Company believes
there exists an even greater need among physicians for clinical management
services and information systems. The Company believes that assisting physicians
in managing the clinical aspects of their practices represents the greatest
opportunity to enhance the quality and reduce the cost of health care.
 
    The Company believes that it is well positioned to attract, organize and
manage physician group practices and networks by offering a full range of
integrated management services and clinical information systems. The Company
believes that its clinical information systems will allow physicians, at the
point of care and on a real-time basis, (i) to access patient-specific clinical
and payor information, (ii) to generate patient instructions, prescriptions and
orders for tests, specialty referrals and specialty procedures and (iii) to
access databases containing managed care and disease management protocols,
diagnostic/treatment preferences and guidelines affecting medical orders. By
combining its group practice and network management services with its clinical
information systems, the Company believes it can provide physicians with
integrated solutions for managing the increased financial opportunities and
risks associated with managed care contracts while allowing physicians to
improve the quality of care.
 
                                       3
<PAGE>
    The Company's strategy includes (i) establishing long-term contractual
alliances with physician organizations, (ii) managing high-cost, high-volume
disease specialties such as cardiology, oncology and orthopedics, (iii)
providing physicians with clinical information at the point of care, (iv)
focusing on selected geographic markets that offer concentrations of physicians
seeking the Company's services and (v) continuing to develop relationships with
key industry participants. The Company has entered into a software license and
integration agreement with Merck Medco Managed Care, Inc. for the Company's
prescription writing software. In addition, the Company has entered into a
contract with an affiliate of PCS Health Systems, Inc., the managed care unit of
Eli Lilly & Company, to provide disease management information services and
software for the treatment of certain diseases.

                                  RISK FACTORS
 
    An investment in the shares of Common Stock offered hereby involves a high
degree of risk. The following factors should be carefully considered in
evaluating the Company and its business before purchasing the shares of Common
Stock offered hereby. The discussion in this Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
could differ materially from those discussed herein. Factors that could cause or
contribute to such differences include, but are not limited to, those discussed
in this section and in the sections entitled "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business," as
well as those discussed elsewhere in this Prospectus.
 
   
LIMITED OPERATING HISTORY; HISTORY OF LOSSES; UNCERTAINTY OF FUTURE
PROFITABILITY; DIRECT CAPITATION
    
 
   
    The Company was incorporated in August 1993, began providing physician
practice and network management services in December 1995 and has only recently
commercially installed its clinical information systems on a limited basis.
Accordingly, the Company has only a limited operating history upon which an
evaluation of the Company and its prospects can be based. As of June 30, 1996,
the Company had an accumulated deficit of approximately $10.6 million. The
Company has never achieved profitability and expects to continue to incur
operating losses through at least the end of 1996. Due to anticipated increases
in operating expenses, the Company's operating results will be adversely
affected if sales of its management services and clinical information systems do
not increase. In addition, the Company's prospects must be considered in light
of the risks, expenses and difficulties frequently encountered by companies in
their early stages of development, particularly companies in rapidly evolving
markets. To address these risks, the Company must, among other things, expand
sales of its physician practice and network management services, commercialize
its clinical information systems, respond to competitive developments and
continue to attract and retain qualified personnel. Accordingly, there can be no
assurance that the Company will be able to generate sufficient revenue to
achieve profitability, to maintain such profitability, if achieved, on a
quarterly or annual basis or to sustain or increase its revenue growth in future
periods. In addition, the Company may in the future enter into direct or
indirect managed care or capitation arrangements pursuant to which the Company
would be subject to significant risk if its revenues were insufficient to cover
increased variable costs resulting from requirements of greater than expected
levels of medical care. See "-- Risks Associated with Direct Capitation,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."
    
 
DEPENDENCE ON MANAGEMENT CONTRACTS WITH AFFILIATED PHYSICIAN GROUPS AND NETWORKS
 
   
    The Company's revenue to date has been derived from a limited number of
management agreements between the Company and certain physician groups and
networks. Such management agreements generally have an initial term of five to
20 years and are automatically renewable for additional terms. See "Risk Factors
- -- Concentration of Revenues" and "Business--Contractual Relationships with
Affiliated Physicians." The termination of any one or more of such management
agreements would have a material adverse effect on the Company's revenues and
results of operations. The Company's future growth and profitability is
substantially dependent upon obtaining new contracts for the provision of
services to physician groups and physician networks on satisfactory terms and
conditions. The Company must accurately assess the costs it will incur in
providing services in order to negotiate contracts on terms under which the
Company can expect to realize adequate profit margins or otherwise meet its
objectives. In addition, the Company must perform services in sufficient volume
to generate revenues to support its infrastructure. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Overview." The
future growth and profitability of the Company is also dependent on the
Company's ability to effectively integrate the practices of its affiliated
physicians, to manage and control costs and to realize economies of scale. The
integration of new physician practice and network management contracts, as well
as the maintenance of existing contracts, is made more difficult by reduced
reimbursement rates of health care payors at a time when the cost of providing
medical services continues to increase. There can be no assurance that the
Company will
    
 
                                       5
<PAGE>
obtain new physician practice and network management contracts on satisfactory
terms, or at all. Any failure of the Company to obtain new contracts and price
its services appropriately would have a material adverse effect on the Company's
business, financial condition and results of operations and the price of the
Common Stock. See "Business -- Physician Practice and Network Services."
 
UNCERTAINTY OF SUCCESSFUL COMMERCIALIZATION OF CLINICAL INFORMATION SYSTEMS
 
    Since its inception in August 1993, the Company has focused on developing
its clinical information systems. However, to date, the Company has commercially
installed its clinical information systems only on a limited basis. The
Company's future growth and profitability is substantially dependent upon the
success of its clinical information systems. The Company believes that market
acceptance of such systems will depend upon the continued growth of managed care
in the Company's markets, the continued increase in the administrative and
clinical complexity of ambulatory medicine, the clinical efficacy of the disease
management programs developed by its affiliated physicians and third parties,
the continued downward trend in the cost of computer hardware, particularly
handheld computing devices and wireless network infrastructures, and the
continued consolidation of physician group practices. No assurance can be given
that the Company's clinical information systems will be accepted or competitive
or that the Company will be successful in taking systems from their current
state of limited commercial introduction to commercial acceptance. If the
Company's clinical information systems do not achieve market acceptance or if
the Company does not develop and maintain sales, marketing and service
expertise, the Company's growth, revenues and results of operations will be
materially adversely affected. See "Business -- Clinical Information Systems."
 
CONCENTRATION OF REVENUES
 
   
    In the year ended December 31, 1995, Madison Medical -- The Private Practice
Group of New York, L.L.P. ("Madison") accounted for approximately 36% of the
Company's revenues. In the six months ended June 30, 1996, Madison and the
Advanced Heart Physicians & Surgeons Network, P.C. ("AHP&S") accounted for
approximately 49% and 23% of revenues, respectively. The Company's management
services agreements generally have an initial term of five to 20 years and may
be terminated only for cause. The management services agreement with Madison,
however, gives Madison the right to terminate without cause following the first
year of the term and prior to the end of the tenth year of the term upon payment
of a penalty and thereafter without penalty. The management services agreement
with AHP&S restricts the Company's ability to provide management services to
certain cardiology physician groups in the New York metropolitan area. In
addition, in the year ended December 31, 1995, the Company's disease management
software license and integration agreement with an affiliate of PCS Health
Systems, Inc., the managed care unit of Eli Lilly & Company, accounted for
approximately 32% of the Company's revenues. Although such affiliate of PCS
Health Systems has agreed to sponsor two pilot programs involving the software
applications developed by the Company, it has no obligation thereafter to use or
distribute the Company's software. Although the Company seeks to build long-term
customer relationships, no assurance can be given that such relationships will
continue. Any termination or significant deterioration of the Company's
relationships with its principal customers could have a material adverse effect
on the Company's business, financial condition and results of operations. In
addition, a deterioration in the financial condition of any of its principal
customers would materially adversely affect the Company's financial condition
and results of operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
    
 
MANAGEMENT OF GROWTH
 
    The Company recently has experienced, and expects to continue to experience,
substantial growth and has significantly expanded, and expects to continue to
expand, its operations. This growth and expansion has placed, and will continue
to place, significant demands on the Company's management, technical, financial
and other resources. To manage growth effectively, the Company must maintain a
high level of operational quality and efficiency, and must continue to enhance
its operational, financial and management systems and to expand, train and
manage its employee base. To date, the Company
 
                                       6
<PAGE>
has only limited experience in providing physician practice and network
management services and clinical information systems. To execute its growth
strategy, the Company plans to significantly increase the number of physician
practices and networks under management, expand its clinical information systems
customer base, develop disease management services and develop a sales and
marketing organization. There can be no assurance that the Company will be able
to manage growth effectively, and any failure to do so could have a material
adverse effect on the Company's business, financial condition and results of
operations and the price of the Common Stock.
 
COST CONTAINMENT AND REIMBURSEMENT TRENDS
 
    The health care industry is experiencing a trend toward cost containment as
government and private third-party payors seek to impose lower reimbursement and
utilization rates and negotiate reduced payment schedules with service
providers. The federal government has implemented, through the Medicare program,
a resource-based relative value scale ("RBRVS") payment methodology for
physician services. This methodology went into effect in 1992 and is continuing
to be implemented in annual increments through December 31, 1996. RBRVS is a fee
schedule that, except for certain geographical and other adjustments, pays
similarly situated physicians the same amount for the same services. The RBRVS
is adjusted each year, and is subject to increases or decreases at the
discretion of Congress. To date, the implementation of RBRVS has reduced payment
rates for certain of the procedures historically provided by the physician
groups and networks managed by the Company. Management estimates that 35% of the
revenues of physician groups managed by the Company are derived from government
sponsored health care programs (principally, Medicare, Medicaid and state
reimbursed programs). RBRVS-type of payment systems have also been adopted by
certain private third-party payors and may become a predominant payment
methodology. More wide-spread implementation of such programs would reduce
payments by private third-party payors. Rates paid by many private third-party
payors, including those that provide Medicare supplemental insurance, are based
on established physician and hospital charges and are generally higher than
Medicare payment rates. A change in the patient mix of the practices under
Company management that results in a decrease in patients covered by private
insurance could adversely affect the Company's results of operations if the
Company is unable to assist physicians in containing the cost of the provision
of medical services. To the extent that affiliated physicians receive lower
revenue for medical services, there can be no assurance that the Company will be
able to derive sufficient revenues from its relationship with any such
affiliated physicians to achieve or maintain profitability. The Company believes
that cost containment trends will continue to result in a reduction from
historical levels in per-patient revenue for medical practices. Further
reductions in payments to physicians or other changes in reimbursement for
health care services could have an adverse effect on the Company's operations,
unless the Company is otherwise able to offset such payment reductions. There
can be no assurance that the effect of any or all of these changes in
third-party reimbursement could be offset by the Company through cost
reductions, increased volume, introduction of new services and systems or
otherwise. See "Risk Factors -- Uncertainty Related to Health Care Reform" and
"Business -- Government Regulation."
 
RISKS ASSOCIATED WITH CAPITATED FEE ARRANGEMENTS
 
    As an increasing percentage of patients are coming under the control of
managed care entities, the Company believes that its success will, in part, be
dependent upon the Company's ability to negotiate and manage, on behalf of
physician practice groups and networks, agreements with health maintenance
organizations ("HMOs"), employer groups and other private third-party payors
pursuant to which professional services will be provided on a risk-sharing or
capitated basis by some or all of the physicians affiliated with the Company.
Under some of such agreements, the health care provider accepts a pre-determined
amount per patient per month in exchange for providing all necessary covered
services to the patients covered by the agreement. Such agreements pass the
economic risk of providing care from the payor to the provider. In the Company's
target markets, capitated fee arrangements are relatively new and the Company
has limited experience in negotiating or managing capitated fee agreements. The
proliferation of such agreements in markets served by the Company could result
in greater predictability of revenues, but not necessarily of profits, for
physicians affiliated with the Company. There can be
 
                                       7
<PAGE>
no assurance that the Company will be able to negotiate, on behalf of the
physicians, satisfactory arrangements on a risk-sharing or capitated basis or
that the physician organizations managed by the Company will be able to provide
medical services at a profit under such arrangements. To the extent affiliated
physicians incur medical costs that limit such affiliated physicians'
profitability, there can be no assurance that the Company will be able to derive
sufficient revenues from its relationship with any such affiliated physicians to
achieve or maintain profitability.
 
RISKS ASSOCIATED WITH DIRECT CAPITATION
 
   
    The Company anticipates entering into managed care or capitated
arrangements, either indirectly, through the assignment of managed care
contracts entered into between its affiliated physicians and third-party payors,
or directly, through the formation of an independent physician association
("IPA"). On August 10, 1995, the National Association of Insurance Commissioners
(the "NAIC") issued a report opining that such risk-transferring arrangements
may entail the business of insurance, to which state licensure laws apply, but
that licensure laws would not apply where the unlicensed entity contracts to
assume "downstream risk" from a duly licensed health insurer or HMO for health
care provided to that carrier's enrollees. The NAIC's conclusions are not
binding on the states. The Company does not now have capitated contracts and
would enter into such contracts only with licensed insurance companies and HMOs,
and only if allowed by state law. To the extent such contracts are prohibited by
the law of any particular state, the Company would not enter into such contracts
in that state. Also, to the extent that the Company accepts capitation and is
regulated as an insurer, regulatory provisions that might mitigate losses by
insurers will not apply to reduce the Company's risk. In addition, the Company
has little experience in managing capitated-risk arrangements. Revenues under
managed care or capitated arrangements entered into by the Company will
generally be a fixed amount per enrollee. Under such an arrangement, the Company
would contract with affiliated physicians for the provision of health care
services and the Company would be responsible for the provision of all or a
portion of the health care requirements of such enrollees. To the extent that
such enrollees require more care than is anticipated by the Company upon
entering into such a contract, the Company's revenues under such contracts may
be insufficient to cover its costs, in which event the Company would suffer a
loss. Although the Company expects to enter into reinsurance agreements with
third-party insurers in respect of such risk, no assurances can be given that
the Company will be able to obtain such reinsurance on favorable terms, if at
all. In addition, the Company has no experience in forming or managing an IPA.
There can be no assurance that the Company will enter into such managed care or
capitation arrangements or, if it does so, that it will realize a profit from
such arrangements. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Contractual Relationships
with Affiliated Physicians -- Capitated and Other Fixed-Fee Arrangements."
    
 
HIGHLY COMPETITIVE INDUSTRY
 
    The physician practice and network management industry is highly
competitive. The industry is also subject to continuing changes in how services
and products are provided and how providers are selected and paid. As prepaid
medical care continues to grow, the Company may encounter increased competition.
Certain companies are expanding their presence in the physician management
market through the use of several approaches. A number of companies provide
broad management services to primary, multi-specialty and specialty physician
groups, while other companies provide claims processing, utilization review and
other more focused management services. In addition, certain of the Company's
competitors are dedicated to the management of single-specialty practices
focused on diseases such as cardiology, oncology and orthopedics. Certain of the
Company's competitors are significantly larger, have access to greater
resources, provide a wider variety of services and products, have greater
experience in providing health care management services and products and/or have
longer established relationships with customers for these services and products.
The Company believes that competition for services is based on cost and quality
of services. There can be no assurance that the Company's strategy will allow it
to compete favorably in contracting with payors or expanding or maintaining its
physician group practices or networks in existing or new markets. In addition,
many
 
                                       8
<PAGE>
health care providers are consolidating to create larger health care delivery
enterprises with greater regional market power. Such consolidation could erode
the Company's customer base and reduce the size of the Company's target market.
In addition, the resulting enterprises could have greater bargaining power,
which could lead to price erosion affecting the Company's services. The
reduction in the size of the Company's target market or the failure of the
Company to maintain adequate price levels could have a material adverse effect
on the Company's business, financial condition and results of operations and on
the price of the Common Stock.
 
    The market for health care information systems is highly competitive and
rapidly changing. The Company believes that the principal competitive factors
for clinical information systems are the usefulness of the data and reports
generated by the software, customer service and support, compatibility with the
customer's existing information systems, potential for product enhancement,
vendor reputation, price and the effectiveness of sales and marketing efforts.
Many of the Company's competitors and potential competitors have greater
financial, product development, technical and marketing resources than the
Company, and currently have, or may develop or acquire, substantial installed
customer bases in the health care industry. In addition, as the market for
clinical information systems develops, additional competitors may enter the
market and competition may intensify. While the Company believes that it has
successfully differentiated itself from competitors, for example, by offering
clinical information systems that provide patient-specific, point-of-care
information, there can be no assurance that, in the future, competition will not
have a material adverse effect on the Company's business, financial condition
and results of operations and on the price of the Common Stock. See "Business --
Competition."
 
GOVERNMENT REGULATION
 
    As a participant in the health care industry, the Company's operations and
relationships are subject to extensive and increasing regulation under numerous
laws administered by governmental entities at the federal, state and local
levels.
 
   
    Anti-kickback Statutes. The fraud and abuse provisions of the Medicare and
Medicaid statutes, which prohibit the solicitation, payment, receipt or offer of
any direct or indirect remuneration for the referral of Medicare or Medicaid
patients or for the order or provision of Medicare or Medicaid covered services,
items or equipment. These laws also impose restrictions on physicians' referrals
for designated health services to entities with which they have financial
relationships. Violations of these laws may result in substantial civil or
criminal penalties for individuals or entities, including large civil monetary
penalties and exclusion from participation in the Medicare and Medicaid
programs. Such exclusion, if applied to the physician groups or networks managed
by the Company, could result in significant loss of reimbursement. Several
states, including states in which the Company operates, have adopted similar
laws that cover patients in private programs as well as government programs.
    
 
   
    Corporate Practice of Medicine. The laws of many states prohibit
non-physician entities from practicing medicine and employing physicians to
practice medicine. The Company, through its majority-owned management service
organizations ("MSOs"), provides only non-medical administrative services and
clinical information systems to physician organizations, does not represent to
the public or its clients that it offers medical services and does not exercise
control over the practice of medicine by the physician organizations with which
it contracts. These limitations on MSO activities are incorporated into each
management service agreement--the contract governing the relationship between an
MSO and the physician group practice or network it serves. Physician group
practices or networks, which deliver medical care, are independent entities from
MSOs, which perform administrative functions and are controlled by the Company.
The Company believes its operations are in material compliance with applicable
laws in all jurisdictions in which it operates. Nevertheless, because of the
structure of its relationship with its affiliated physician groups and networks,
many aspects of the Company's business operations have not been the subject of
state or federal regulatory interpretation and there can be no assurance that a
review of the Company's or its affiliated physicians' businesses by courts or
regulatory authorities will not result in a determination that could adversely
affect the
    
 
                                       9
<PAGE>
operations of the Company or its affiliated physicians (for example, by
rendering the Company's management services agreements with a physician
organization unenforceable) or that the health care regulatory environment will
not change so as to restrict the Company's or its affiliated physicians'
existing operations or expansion. In addition, recently released regulations
dealing with the use of physician incentives may restrict the extent to which
payors or the Company may impose financial risk upon physicians (or other
providers). Violation of such regulations could result in substantial penalties.
Such regulations may reduce the Company's ability to control its expenses.
 
   
    Confidentiality of Patient Records. The confidentiality of patient records
and the circumstances under which such records may be released are subject to
substantial regulation by state and federal laws and regulations, which govern
both the disclosure and use of confidential patient medical record information.
The Company believes that it complies with the laws and regulations regarding
the collection and distribution of patient data in all jurisdictions in which it
operates, but regulations governing patient confidentiality rights are evolving
rapidly and are often unclear and difficult to apply in the rapidly
restructuring health care market. Additional legislation governing the
dissemination of medical record information is continually being proposed at
both the state and federal level. Such proposed legislation could require
patient consent before even coded or anonymous patient information may be shared
with third parties and that holders or users of such information implement
security measures. In addition, the American Medical Association (the "AMA") has
issued a Current Opinion to the effect that a physician who does not obtain a
patient's consent to disclosure of patient information for commercial purposes,
including anonymous disclosure, violates the AMA's ethical standards with
respect to patient confidentiality. While the AMA's Current Opinions are not
law, they may influence physicians' willingness to obtain patient consents or
agree to permit the Company to access clinical data in their systems without
such consents. Any such restrictions could have a material adverse effect on the
Company's ability to market its services and systems. Although the Company
intends to safeguard patient privacy when clinical data is accessed and to enter
patient medical information into or receive such information from its database
only with the consent of the patient, if a patient's privacy is violated, the
Company could be liable for damages incurred by such patients. There can be no
assurance that changes to state or federal laws will not materially restrict the
ability of the Company to obtain or disseminate patient information. See
"Business -- Government Regulation."
    
 
FDA REGULATION
 
    Products, including software applications, intended for use in the diagnosis
of disease or other conditions, or in the cure, treatment, mitigation or
prevention of disease, are subject to regulation by the United States Food and
Drug Administration (the "FDA") as medical devices. The laws administered by the
FDA impose substantial regulatory controls over the manufacturing, labeling,
testing, distribution, sale, marketing and promotion of medical devices and
other related activities. These regulatory controls can include compliance with
the following requirements: manufacturer establishment registration and device
listing; current good manufacturing practices; FDA clearance of a premarket
notification submission or FDA approval of a premarket approval application;
medical device adverse event reporting; and general prohibitions on misbranding
and adulteration. Violations of the laws concerning medical devices can result
in, among other things, severe criminal and civil penalties, product seizure,
recall, repair or refund orders, withdrawal or denial of premarket notifications
or premarket approval applications, denial or suspension of government contracts
and injunctions against unlawful product manufacture, labeling, promotion and
distribution or other activities. In its 1989 Draft Policy for the Regulation of
Computer Products (the "1989 Draft Policy Statement"), the FDA stated that it
intended to exempt certain clinical decision support software products from a
number of regulatory controls, and that until those regulations were issued it
would not require manufacturers of such products to comply with requirements
other than the prohibitions on misbranding and adulteration. The Company
believes that its clinical information systems are not medical devices and,
thus, are not subject to the controls imposed on manufacturers of such products
and do not fall within the scope of the 1989 Draft Policy Statement. The Company
further believes that to the extent that its systems were determined to be
medical devices, the systems would fall within the exemptions for decision
support
 
                                       10
<PAGE>
systems provided by the 1989 Draft Policy Statement. The Company has not sought
or obtained a formal opinion of counsel with respect to the issue of FDA
exemption nor has the Company taken action to comply with the controls that
would otherwise apply if the Company's systems were determined to be non-exempt
medical devices. The FDA has stated that it intends to revise its 1989 Draft
Policy Statement and that it may eliminate some or all of the exemptions that it
currently allows. Accordingly, there can be no assurance that the FDA will not
now or in the future make a determination that the Company's current or future
clinical information systems are medical devices subject to FDA regulations and
are ineligible for the exemptions from those regulations. Furthermore, there can
be no assurance that the Company would be able to comply in a timely manner, if
at all, with FDA regulations if the agency made such determinations. Thus, such
determinations by the FDA could significantly delay, or even prevent, the
Company's ability to offer its systems and could otherwise have a material
adverse effect on the Company's business, financial condition and results of
operations and on the price of the Common Stock. See "Business -- Government
Regulation."
 
UNCERTAINTY RELATED TO HEALTH CARE REFORM
 
    The Company anticipates that Congress and state legislatures will continue
to review and assess alternative health care delivery and payment systems.
Potential approaches that have been considered include mandated basic health
care benefits, controls on health care spending through limitations on the
growth of private health insurance premiums and Medicare and Medicaid spending,
the creation of large insurance purchasing groups and other fundamental changes
to the health care delivery system. Proposals have also been discussed which
would provide incentives for the provision of cost-effective, quality health
care through formation of regional delivery systems. Private sector providers
and payors have embraced certain elements of reform, resulting in increased
consolidation of medical groups and competition among managers of medical
practice groups as these providers and payors seek to form alliances in order to
provide quality, cost-effective care. Due to uncertainties regarding the
ultimate features of reform initiatives and their enactment and implementation,
the Company cannot predict which, if any, of such reform proposals will be
adopted, when they may be adopted or what impact they may have on the Company,
and there can be no assurance that the adoption of reform proposals will not
have a material adverse effect on the Company's business, operating results or
financial condition. In addition, the announcement of reform proposals and the
investment community's reaction to such proposals, as well as announcements by
competitors and third-party payors of their strategies to respond to such
initiatives, could produce volatility in the trading and market price of the
Common Stock. See "Business -- Government Regulation."
 
TECHNOLOGICAL CHANGE
 
    The health care information industry is relatively new and is experiencing
rapid technological change, changing customer needs, frequent new product
introductions and evolving industry standards. In addition, as the computer and
software industries continue to experience rapid technological change, the
Company must be able to quickly and successfully adapt its clinical information
systems so that they continue to integrate well with the computer platforms and
other software employed by its customers. There can be no assurance that the
Company will not experience difficulties, including lack of necessary capital or
expertise, that could delay or prevent the successful development and
introduction of system enhancements or new systems in response to technological
changes. The Company's inability to respond to technological changes in a timely
and cost-effective manner could have a material adverse effect on the Company's
business, financial condition and results of operations and on the price of the
Common Stock. See "Business -- Clinical Information Systems."
 
DEPENDENCE ON PROPRIETARY ASSETS
 
    The Company has made significant investments in its clinical information
systems and relies on a combination of patent, trade secret and copyright laws,
nondisclosure and other contractual provisions and technological measures to
protect its proprietary rights. The Company has two U.S. patent applications and
a foreign patent application commensurate with both U.S. applications but no
issued patents. There can be no assurance that any patent will be issued or, if
issued, that such patent or any
 
                                       11
<PAGE>
other protections will be adequate or that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to those of the Company. In addition, there can be no assurance that the legal
protections and precautions taken by the Company will be adequate to prevent
infringement or misappropriation of the Company's proprietary assets.
 
    Although the Company believes that its clinical information systems do not
infringe upon the proprietary rights of third parties, there can be no assurance
that third parties will not assert infringement claims against the Company in
the future or that a license or similar agreement will be available on
reasonable terms in the event of an unfavorable outcome on any such claim. In
addition, any such claim may require the Company to incur substantial litigation
expenses or subject the Company to significant liabilities and could have a
material adverse effect on the Company's business, financial condition and
results of operations and the price of the Common Stock.
 
   
    The Company is aware that a third party has filed a notice of opposition and
extensions of time to file notices of opposition with respect to certain of the
Company's pending trademark registration applications containing the suffix
"e-systems". Although the Company believes that it will be able to obtain the
registrations applied for, no assurance can be given that it will be able to do
so. In the event of any successful opposition, the Company might be required to
change the trademark used for certain of its clinical information systems. The
Company does not believe that such a result would have a material adverse effect
on its business. See "Business -- Proprietary Rights."
    
 
MANAGEMENT SERVICES ORGANIZATIONS NOT WHOLLY-OWNED; PHYSICIAN PUT RIGHTS;
DILUTION
 
   
    The Company typically establishes an MSO for each physician practice group
or network to which it provides services, which MSO is majority-owned by the
Company. The physician group or network served typically has a minority interest
in the MSO. The MSO's assets consist primarily of its management service
contracts with the physician group or network served and its liabilities consist
primarily of its obligations under its agreements with the Company and its
obligations to its employees. Although the Company has sufficient interests in
the MSOs to exercise control over them, the Company may owe a fiduciary duty to
the holders of various minority interests in such MSOs. Accordingly, the
Company, in exercising control over such MSOs, may be required to deal with them
on terms no less favorable to such MSOs than could be obtained from unaffiliated
third parties.
    
 
    Under certain specified circumstances, the Company has the option to cause
certain MSOs to be merged with and into a wholly-owned subsidiary of the Company
in a transaction in which the interests of the physician groups and networks in
such MSOs would be exchanged for Common Stock of the Company (the "Roll Up
Transaction"). The Company has reserved 548,224 shares of Common Stock for
issuance upon consummation of the Roll Up Transaction, all of which shares are
required to be issued if the Company effects the Roll Up Transaction.
Accordingly, the Roll Up Transaction, if effected, will be dilutive to
investors. In addition, certain of the physician groups and networks managed by
the Company have rights to require the Company to purchase all or part of such
physicians' interest in their respective MSOs in the event that the Company does
not consummate the Roll Up Transaction within one year after the satisfaction of
specified conditions. There can be no assurance that the Company will have the
financial resources to purchase such interests in accordance with its
obligations at the time any such rights are exercised, or that the Company would
be able to obtain financing on satisfactory terms or conditions, if at all, to
purchase such interests. To the extent that any future financing requirements
with respect to such put rights are satisfied through the issuance of equity
securities, investors may experience dilution. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business --
Contractual Relationships with Affiliated Physicians."
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's ability to market and deliver its services and systems and to
achieve and maintain a competitive position is dependent in large part upon the
efforts of its senior management, particularly Jonathan Edelson, M.D., the
Company's Chairman of the Board and Chief Executive Officer, and Steven
Hochberg, the Company's President. Although the Company is the beneficiary of
$250,000 "key
 
                                       12
<PAGE>
man" life insurance policies on the lives of each of Dr. Edelson and Mr.
Hochberg, the Company does not believe such amount would be adequate to
compensate for the loss of the services of either executive. In addition,
although the Company has entered into employment agreements with most of its
senior executives, including Dr. Edelson and Mr. Hochberg, such agreements will
not assure the services of such employees. The loss of the services of one or
more members of its senior management could have a material adverse effect on
the Company. The Company's future success also will depend upon its ability to
attract and retain qualified management, technical and marketing employees to
support its future growth. Competition for such personnel is intense, and there
can be no assurance that the Company will be successful in attracting or
retaining such personnel. The failure to attract and retain such persons could
materially adversely affect the Company. See "Management."
 
RISK OF LIABILITY CLAIMS
 
    Customer reliance on the Company's services and systems could result in
exposure of the Company to liability claims if the Company's services and
systems fail to perform as intended or if patient care decisions based in part
on guidance from the Company's services and systems are challenged. Even
unsuccessful claims could result in the expenditure of funds in litigation,
diversion of management time and resources or damage to the Company's reputation
and the marketability of the Company's services and systems. While no such
claims have been made against the Company to date, and although the Company
takes contractual steps to obtain indemnification for certain liabilities and
maintains general commercial liability insurance, there can be no assurance that
a successful claim could not be made against the Company, that the amount of
indemnification payments or insurance would be adequate to cover the costs of
defending against or paying such a claim or that the costs of defending against
such a claim or the payment of damages by the Company would not have a material
adverse effect on the Company's business, financial condition and results of
operations and on the price of the Common Stock.
 
NO PRIOR PUBLIC MARKET; OFFERING PRICE DETERMINED BY AGREEMENT; VOLATILITY OF
STOCK PRICE
 
    Prior to this offering, there has been no public market for the Common
Stock. Although the Common Stock has been approved for quotation on the Nasdaq
National Market, subject to official notice of issuance, there can be no
assurance that an active trading market for the Common Stock will develop or
continue after this offering. The initial public offering price of the Common
Stock will be determined by negotiation between the Company and the
Representatives of the Underwriters, and may not be indicative of the market
price for the Common Stock after this offering. See "Underwriting." From time to
time after this offering, there may be significant volatility in the market
price for the Common Stock. Results of the Company's operations may fluctuate
significantly from quarter to quarter and will depend on numerous factors,
primarily the timing of the addition of new physician practice groups and
networks under management and the sale of clinical information systems and
associated services. Such fluctuations in quarterly operating results of the
Company, changes in general conditions in the economy, the financial markets or
the health care industry or other developments affecting the Company or its
competitors could cause the market price of the Common Stock to fluctuate
substantially. In addition, in recent years the stock market has experienced
extreme price and volume fluctuations. This volatility has had a significant
effect on the market prices of securities issued by many companies for reasons
unrelated to their operating performance.
 
DILUTION
 
    The purchasers of the shares of Common Stock offered hereby will experience
immediate and substantial dilution in the pro forma net tangible book value of
their shares of Common Stock in the amount of $8.86 per share, at an assumed
initial public offering price of $12.00 per share (after deducting underwriting
discounts and commissions and estimated offering expenses). Such investors will
experience additional dilution upon the exercise of outstanding options and
warrants. In addition, in the event the Company issues additional Common Stock
in the future, including shares that may be issued in connection with the Roll
Up Transaction or future acquisitions, investors may experience
 
                                       13
<PAGE>
further dilution. See "Dilution," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business -- Contractual
Relationships with Affiliated Physicians."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
    Sales of shares of Common Stock (including shares issued upon the exercise
of outstanding options) in the public market after this offering could adversely
affect the market price of the Common Stock. Such sales also might make it more
difficult for the Company to sell equity securities or equity-related securities
in the future at a time and price that the Company deems appropriate. Upon
completion of this offering, the Company will have approximately 6,500,267
shares of Common Stock outstanding. The 2,000,000 shares offered hereby will be
freely tradeable without restriction unless they are held by "affiliates" of the
Company as the term is used under the Securities Act of 1933 (the "Securities
Act") and the regulations promulgated thereunder. The remaining approximately
4,500,267 shares are restricted securities that may be sold only if registered
under the Securities Act or sold in accordance with an applicable exemption from
registration, such as Rule 144 promulgated under the Securities Act. As a result
of the contractual restrictions described below and the provisions of Rules 144,
144(k) and 701 under the Securities Act, additional shares will be available for
sale in the public market as follows: (i) no shares of Common Stock (other than
those shares sold hereby and not held by affiliates) will be available for
immediate sale in the public market on the date of this Prospectus, (ii) 19,272
shares of Common Stock subject to options exercisable within 90 days of the date
of this Prospectus will be freely tradeable by non-affiliates upon the
effectiveness of a registration statement relating to such stock options, (iii)
224,566 shares of Common Stock and 18,432 shares of Common Stock subject to
options exercisable within 90 days of the date of this Prospectus will be
eligible for sale 90 days after the date of this Prospectus, subject to the
volume, manner of sale and reporting requirements of Rule 144, and (iv)
approximately 4,266,800 shares of Common Stock and approximately 9,500 shares of
Common Stock subject to options exercisable within 180 days of the date of this
Prospectus will be eligible for sale upon expiration of the lock-up agreements
180 days after the date of this Prospectus, subject to the volume, manner of
sale and reporting requirements of Rule 144. The holders of 2,941,985 shares of
Common Stock have the right in certain circumstances to require the Company to
register their shares under the Securities Act for resale to the public. If such
holders, by exercising their demand registration rights, cause a large number of
shares to be registered and sold in the public market, such sales could have an
adverse effect on the market price for the Company's Common Stock. If the
Company were required to include in a Company-initiated registration shares held
by such holders pursuant to the exercise of their "piggyback" registration
rights, such sales may have an adverse effect on the Company's ability to raise
needed capital. See "Shares Eligible for Future Sale," "Description of Capital
Stock" and "Underwriting."
 
UNSPECIFIED USE OF PROCEEDS
 
    Following this offering, the Company will have approximately $16.4 million
($19.7 million if the Underwriters' over-allotment option is exercised in full)
of the net proceeds of this offering available for working capital and general
corporate purposes, which may include acquisitions. The Company's management,
subject to approval by the Board of Directors in certain circumstances, will
have broad discretion with respect to the application of such proceeds. See "Use
of Proceeds."
 
POTENTIAL ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE COMPANY'S
CERTIFICATE OF INCORPORATION AND BY-LAWS AND THE DGCL
 
    The Company's Restated Certificate of Incorporation (the "Certificate of
Incorporation") and By-laws (the "By-laws") and the Delaware General Corporation
Law (the "DGCL") contain provisions which may have the effect of delaying,
deterring or preventing a future takeover or change in control of the Company
unless such takeover or change in control is approved by the Company's Board of
Directors. Such provisions may also render the removal of directors and
management more difficult. The Certificate of Incorporation and By-laws provide
for, among other things, a classified Board of Directors serving staggered terms
of three years, certain advance notice requirements for stockholder nominations
of candidates for election to the Board of Directors and certain other
stockholder proposals,
 
                                       14
<PAGE>
restrictions on who may call a special meeting of stockholders and a prohibition
on stockholder action by written consent. In addition, the Company's Board of
Directors has the ability to authorize the issuance of up to 5,000,000 shares of
preferred stock in one or more series and to fix the voting powers,
designations, preferences and relative, participating, optional and other
special rights and qualifications, limitations or restrictions thereof without
stockholder approval. The DGCL also contains provisions preventing certain
stockholders from engaging in business combinations with the Company, subject to
certain exceptions. See "Description of Capital Stock."
 
INVESTMENT COMPANY ACT CONSIDERATIONS
 
    The Investment Company Act of 1940, as amended (the "1940 Act"), requires
the registration of, and imposes various substantive restrictions on, certain
companies that engage primarily, or propose to engage primarily, in the business
of investing, reinvesting or trading in securities, or that fail certain
statistical tests regarding the composition of assets and sources of income, and
are not primarily engaged in business other than investing, holding, owning or
trading securities. The Company believes that it is, and it intends to remain,
primarily engaged in business other than investing, holding, owning or trading
securities. The Company will seek to invest temporarily the proceeds of this
offering, pending their use as described under the caption "Use of Proceeds,"
and to utilize the proceeds of this offering in the manner described under "Use
of Proceeds," so as to avoid becoming subject to the registration requirements
of the 1940 Act. Such investment is likely to result in the Company obtaining
lower yields on the funds invested than might be available in the securities
markets generally. There can be no assurance, however, that such investments and
utilization can be made. If the Company were required to register as an
investment company under the 1940 Act, it would become subject to substantial
regulation with respect to its capital structure, management, operations,
transactions with affiliates, and other matters.

<PAGE>
                                  THE COMPANY
 
    The Company's predecessor, Med-E-Systems Corporation ("MES"), was
incorporated on August 27, 1993 as a clinical information systems development
company. Effective August 23, 1995, MES became a subsidiary of the Company
through a tax-free reorganization. The Company was subsequently merged with and
into Majean, Inc., a Delaware corporation, and the surviving corporation changed
its name to Advanced Health Corporation. The Company's executive offices are
located at 560 White Plains Road, Tarrytown, New York 10591, and its telephone
number at that address is (914) 524-4200.
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be approximately $21.5 million ($24.8 million if
the Underwriters' over-allotment option is exercised in full), at an assumed
initial public offering price of $12.00 per share and after deducting
underwriting discounts and commissions and estimated offering expenses.
 
    The Company will use approximately $5.1 million of the net proceeds of this
offering to repay an aggregate of $5.0 million principal amount of indebtedness,
plus interest, including the repayment of an aggregate of $2.0 million principal
amount of indebtedness, plus interest, to certain 21st Century Partnerships.
21st Century Partnerships is a principal stockholder of the Company. See
"Principal Stockholders." The Company issued three 8% promissory notes in the
principal amounts of $1.5 million, $750,000 and $750,000 on February 28, April
26 and June 28, 1996, respectively. The Company issued six 9% promissory notes
in an aggregate principal amount of $2.0 million on June 19 and August 13, 1996
to certain 21st Century Partnerships. All of such notes will mature on the
earlier of the consummation of this offering and the one-year anniversary of
their issuance, in the case of the 8% notes, or July 31, 1997, in the case of
the 9% notes. The proceeds of such notes are being used to finance working
capital. See "Certain Transactions."
 
    The Company intends to use the balance of the net proceeds, approximately
$16.4 million, for working capital and general corporate purposes, which may
include acquisitions. From time to time in the ordinary course of its business,
the Company evaluates possible acquisitions of businesses, products and
technologies that are complementary to those of the Company. The Company
currently has no agreements or understandings, and is not engaged in active
negotiations, with respect to any such acquisition.
 
    Pending the application of the net proceeds of this offering, the Company
intends to invest such proceeds in short-term, investment-grade,
interest-bearing instruments or money market funds.
 
                                DIVIDEND POLICY
 
    The Company has not declared or paid any cash dividends on its capital stock
since inception and does not expect to pay dividends in the foreseeable future.
The Company presently intends to retain future earnings, if any, to finance the
expansion of its business. The payment of any cash dividends in the future will
depend on the Company's earnings, financial condition, results of operations,
capital needs, and other factors deemed pertinent by the Company's Board of
Directors, subject to laws and regulations then in effect.

    The net tangible book value of the Company as of June 30, 1996 was
$(1,048,338), or $(0.23) per share of Common Stock on a pro forma basis, after
giving effect to the Stock Splits and the Preferred Stock Conversion. "Net
tangible book value per share" represents the amount of the Company's total
tangible assets less the Company's total liabilities, divided by the number of
shares of Common Stock outstanding. After giving effect to the sale of 2,000,000
shares of Common Stock offered hereby at an assumed initial public offering
price of $12.00 per share (after deducting underwriting discounts and
commissions and estimated offering expenses), and the initial application of the
net proceeds therefrom, the pro forma net tangible book value of the Company at
June 30, 1996 would have been $20,421,662, or $3.14 per share of Common Stock.
This represents an immediate increase in pro forma net tangible book value of
$3.37 per share to existing stockholders and an immediate, substantial dilution
in pro forma net tangible book value per share of $8.86 per share to purchasers
of shares of Common Stock offered hereby, as illustrated in the following table:

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion of the results of operations and financial
condition of the Company should be read in conjunction with the Consolidated
Financial Statements and the notes thereto included elsewhere in this
Prospectus.
 
OVERVIEW
 
    The Company provides a full range of integrated management services and
clinical information systems to physician group practices and physician
networks. The Company generates revenues from (i) fees for managing and
providing consulting services to physician group practices, (ii) fees for
managing physician networks and (iii) fees for use and support of its clinical
information systems, including recurring license, software installation,
software integration, training and data conversion fees. The Company contracts
with its physician practice and network management clients pursuant to long-term
agreements with its MSOs, the results of which MSOs are consolidated in the
Consolidated Financial Statements.
 
   
    Through its MSOs, the Company enters into long-term management services
agreements with physician group practices, whereby such physician group
practices outsource their non-medical and administrative functions to an MSO.
The Company generates revenues from its physician practice clients in return for
the provision of various management services, including general administrative
services, billing and collection services and capitated contract management
services. Revenue resulting from general administrative services provided by the
Company varies depending on the level of monthly services performed. At the end
of every six-month period, if the Company has caused the group practice's
administrative overhead to be reduced as a result of its delivery of management
services, then the Company receives an additional fee typically equal to 50% of
the savings created. Monthly revenue resulting from the Company's provision of
billing and collection services is based on a percentage of revenue collected by
the Company during the previous month on behalf of the group practice. This
percentage fee is either fixed or based on the size of the collections made
during a given month. With respect to management services provided to physician
groups relating to capitated contracts, the Company typically receives a fee
equal to a percentage of the savings recognized by the group practice as a
result of the Company's management of a given capitated contract. This fee is
mutually agreed upon by the group practice and the Company on a
contract-by-contract basis. The Company manages four medical practices
consisting of more than 75 physicians in the greater New York metropolitan area.
The Company also provides physician group consulting services to more than 100
physicians. The Company's strategy to achieve profitability involves the
rendering of management services to physician practices and networks to an
extent large enough to support the Company's infrastructure for the purpose of
providing such services. See "Business -- Physician Practice and Network
Services -- Physician Practice Services."
    
 
   
    Through its MSOs, the Company enters into management service agreements with
physician networks, pursuant to which the aggregate capitated payments to be
made by a third-party payor to such network are assigned to the MSO. The Company
generates revenue from its physician network clients in return for the provision
of various management services. For certain of the Company's current physician
network clients, revenue is based on a percentage of total revenue generated by
the network from fee-for-service or capitated contracts. These revenues are
earned by the Company for the provision of management services regardless of the
amount of medical services provided by the network. With respect to management
services provided for fee-for-service contracts entered into by a network, the
Company typically earns monthly revenue in an amount equal to (i) all
administrative fees included in such fee-for-service contract and (ii) a
management processing fee mutually agreed to by the network and the Company
prior to the execution by the network of any such fee-for-service contract.
    
 
                                       20
<PAGE>
   
    With respect to risk-based contracts for which only professional medical
fees have been capitated, the Company typically earns monthly revenues for
providing management services relating to such contract, not to exceed an agreed
upon fixed percentage of monthly capitated revenue generated by that contract.
In addition, the Company typically receives an incentive fee related to such
contracts in an amount equal to 50% of any amounts deposited at the beginning of
a month in a professional services withhold reserve account and not paid out of
that account during that period. The amount typically deposited in the withhold
account is equal to 10% of the capitated payments made to the network pursuant
to such contract. Funds remain in this account at the end of the month so long
as the physician network delivers professional services during such month at the
rate predicted by standard actuarial analysis. To the extent that funds in
excess of amounts deposited in such account are required to reimburse the
network physicians, the Company will bear its proportional risk of such loss.
    
 
   
    With respect to risk-based contracts for which both professional medical
fees and hospital fees have been capitated, the Company typically earns revenue
equal to a percentage of (i) any amounts paid to the network relating to
hospital-based medical services during a given period pursuant to such contract
minus (ii) the amount of hospital-based medical service costs incurred by the
network during such period. To the extent that amounts in excess of such funds
are required to reimburse the network physicians, the Company will bear its
proportional risk of such loss.
    
 
   
    With respect to the assignment of capitation revenues to the Company, the
Company is dependent on the physician group practices and networks entering into
such agreements, the terms and conditions of which are determined by the
physicians in their sole discretion and providing medical services thereunder.
In addition, the Company is dependent upon the continued alliance of the
physicians with the group practice and network clients of the Company. The
Company will recognize in its financial statements, however, only those revenues
associated with the provision of its management services.
    
 
   
    The Company anticipates that in the future it may form for-profit IPAs, in
states that permit such entities, that will enter into capitated contracts with
healthcare payors. In such event, the for-profit IPA will be directly
responsible for subcontracting with physician networks to provide medical
services under such capitated contracts. The for-profit IPA will assume all the
risk related to providing necessary medical services in a cost-effective manner.
The Company manages eight physician networks, and is developing additional
networks, primarily in the fields of cardiology, oncology and orthopedics. See
"Business -- Physician Practice and Network Services -- Physician Network
Services."
    
 
   
    As described above, the payor contracts contain risk-sharing provisions
whereby incentive revenue can be earned or losses incurred, by the physician
networks, based on the utilization of physician and hospital services by
assigned enrollees. There can be no assurance that the Company will be able to
negotiate, on behalf of the physicians, satisfactory arrangements on a
risk-sharing or capitated basis or that the physician organizations managed by
the Company will be able to provide medical services at a profit under such
arrangements. To the extent affiliated physicians incur medical costs that limit
their profitability, there can be no assurance that the Company will be able to
derive profits from any such affiliated relationship.
    
 
   
    As described above, the Company anticipates entering into managed care or
capitated arrangements, either indirectly, through the assignment of managed
care contracts entered into between its affiliated physicians and third-party
payors, or directly, through the formation of an IPA. On August 10, 1995, the
NAIC issued a report opining that such risk-transferring arrangements may entail
the business of insurance, to which state licensure laws apply, but that
licensure laws would not apply where the unlicensed entity contracts to assume
"downstream risk" from a duly licensed health insurer or HMO for health care
provided to that carrier's enrollees. The NAIC's conclusions are not binding on
the states. The Company does not now have capitated contracts and would enter
into such contracts only with licensed insurance companies and HMOs, and only if
allowed by state law. To the extent such contracts are prohibited by the law of
any particular state, the Company would not enter into such a contract in that
state. Also, to the extent that the Company accepts capitation and is regulated
as an
    
 
                                       21
<PAGE>
   
insurer, regulatory provisions that might mitigate losses by insurers will not
apply to reduce the Company's risk. In addition, the Company has little
experience in managing capitated-risk arrangements and has no experience in
forming or managing an IPA. Revenues under any such arrangements entered into by
the Company would generally be a fixed amount per enrollee. Under such an
arrangement, the Company would contract with affiliated physicians for the
provision of health care services and the Company would be responsible for the
provision of all or a portion of the health care requirements of such enrollees.
To the extent that enrollees require more care than is anticipated by the
Company upon entering into such a contract, the Company's revenues under such
contracts may be insufficient to cover its costs. The Company expects to enter
into reinsurance agreements with third-party insurers in respect of a portion of
its risk under such arrangements. See "Business -- Contractual Relationships
with Affiliated Physicians -- Capitated and Other Fixed-Fee Arrangements."
    
 
    The Company recognizes revenue from the sale and license of its clinical
information systems upon installation and acceptance, and from software
development and integration as services are provided. The Company has only
recently begun to generate revenues from the commercial sale and installation of
its clinical information systems. The Company has made substantial investment in
the development of its clinical information systems and expects to continue such
investment in the future.
 
    To date, the Company has been dependent on a small number of contracts to
generate the majority of its revenues. In the year ended December 31, 1995,
approximately 68% of the Company's revenues were derived from its contracts with
Madison and an affiliate of PCS Health Systems, Inc., the managed care unit of
Eli Lilly & Company, while in the six months ended June 30, 1996, approximately
72% of the Company's revenues were derived from its contracts with Madison and
AHP&S. The Company expects that the concentration of its revenues will be
reduced as the Company enters into additional contracts to provide management
services and clinical information systems to physician organizations.
 
    The Company believes that its historical results of operations from period
to period are not comparable and that such results are not necessarily
indicative of results for any future periods because the Company was a
development stage company investing in technology development and did not
provide physician practice and network management services prior to December 11,
1995.
 
ACQUISITIONS
 
    On August 28, 1995, the Company acquired certain assets and assumed certain
liabilities of Peltz Ventimiglia, Inc. ("Peltz"), a physician practice
management consulting company with physician clients located throughout the East
Coast of the United States, for 75,996 shares of Common Stock and contingent
warrants to purchase 113,995 shares of Common Stock at $4.38 per share. The
warrants are only exercisable, as contingent consideration, based on the
achievement of targeted operating performance criteria. The audited financial
statements of Peltz are included elsewhere in this Prospectus.
 
    On September 1, 1995, the Company acquired U.S. Health Connections, Inc.
("Health Connections"), a network management company servicing the Southeastern
United States and headquartered in Atlanta, Georgia, for $150,000 in cash,
30,193 shares of the Common Stock and $150,000 in notes payable. As of June 30,
1996, $75,000 of notes payable remained outstanding. The purchase price also
included an additional 56,611 shares of Common Stock issued into escrow at
closing. These escrowed shares represent contingent consideration that will be
released from escrow based on the achievement of targeted operating performance
criteria. The audited financial statements of Health Connections are included
elsewhere in this Prospectus.
 
    On April 1, 1996, the Company acquired certain assets of Benenson &
Associates, Inc. ("Benenson"), a physician network development company with
approximately 10 network clients located throughout the East Coast of the United
States, for 8,937 shares of Common Stock and $45,000 in cash, payable in two
installments of $22,500 each on the closing date and the first anniversary
thereof.

RESULTS OF OPERATIONS
 
Six Months Ended June 30, 1996 and 1995
 
    Net revenue for the six months ended June 30, 1996 increased to $7.6 million
from $100,000 in the comparable period ended June 30, 1995, primarily as a
result of the initiation of the Company's physician group practice and network
management services. The Company began providing physician group practice
management and related services to Madison in December 1995 and to AHP&S in
January 1996. The provision of physician group practice management and related
services accounted for approximately $5.8 million of the Company's net revenue
for the six months ended June 30, 1996. The provision of physician network
management services accounted for approximately $273,000 of the Company's net
revenue for the six months ended June 30, 1996. The Company earned fees for the
use and support of its clinical information systems, including the recognition
of license revenues under its contract with Merck Medco Managed Care, Inc., and
software installation and training revenues, of approximately $1.5 million for
the six months ended June 30, 1996, as compared to approximately $100,000 of
such revenues for the comparable period ended June 30, 1995.
 
    Cost of sales for the six months ended June 30, 1996 increased to $3.5
million from $21,822 for the comparable period ended June 30, 1995. The increase
in cost of sales related primarily to the non-medical and system expenses
outsourced to the Company from Madison and AHP&S.
 
    Operating expenses for the six months ended June 30, 1996 increased to $4.0
million from $616,503 for the comparable period ended June 30, 1995. The
increase in operating expenses reflected expenses related to the provision of
management services for the six months ended June 30, 1996, whereas the Company
was a development stage company for the comparable period ended June 30, 1995.
 
    Research and development expenses for the six months ended June 30, 1996
increased to $1.9 million from $1.5 million for the comparable period ended June
30, 1995, due to an increase in the Company's development activities for its
clinical information systems.
 
    Other expense for the six months ended June 30, 1996 was $53,628 and related
to interest on capital lease obligations and interest on $3.0 million and $1.0
million of indebtedness issued as of June 20, 1996, bearing interest at 8% and
9%, respectively. The Company incurred no interest expense for the comparable
period ended June 30, 1995.
 
    The net loss for the six months ended June 30, 1996 was $1.9 million
compared to a loss of $2.0 million for the six months ended June 30, 1995.
 
Year Ended December 31, 1995 and 1994
 
    Net revenue for the year ended December 31, 1995 increased to $1.1 million
from $378,878 in the year ended December 31, 1994, primarily as a result of the
initiation of the Company's physician group practice services to Madison in
December 1995, which generated approximately $505,000 of the Company's net
revenue for the year ended December 31, 1995. The Company began to provide
physician network management services in September 1995, which accounted for
approximately $163,000 of the Company's net revenue for the year ended December
31, 1995. The Company earned fees for the use and support of its clinical
information systems, including the recognition of license revenues under its
contract with an affiliate of PCS Health Systems, Inc., the managed care unit of
Eli Lilly & Company, and software installation and training revenues, of
approximately $386,000 for the year ended December 31, 1995, as compared to
$378,878 of such revenues for the year ended December 31, 1994.
 
    Operating expenses for the year ended December 31, 1995 increased to $3.3
million from $1.3 million for the year ended December 31, 1994. The increase in
operating expenses was due to the increases in staffing and general corporate
expenses required to fund the Company's transition from a
 
                                       23
<PAGE>
development stage company involved in the development of clinical information
systems to a full service physician practice and network management company.
 
    Research and development expenses for the year ended December 31, 1995
increased to $3.2 million from $1.6 million, due to an increase in the Company's
development activities for its clinical information systems.
 
    The net loss for the year ended December 31, 1995 was $5.7 million compared
to a loss of $2.5 million for the year ended December 31, 1994.
 
    As of December 31, 1995, the Company had net operating loss carryforwards
("NOLs") available to offset future book and taxable income of approximately
$8.7 million and $6.2 million, respectively, which expire through 2010. The
difference between the book and tax NOLs relates principally to the differences
between book and tax accounting with respect to start-up costs, depreciation of
fixed assets, amortization of intangible assets and recognition of deferred
revenue. The book income tax benefits of $3.5 million and $1.3 million as of
December 31, 1995 and December 31, 1994, respectively, have been fully reserved
due to the uncertainty of their future realization.
 
Year Ended December 31, 1994 and Period from Inception (August 27, 1993) through
December 31, 1993
 
    Net revenue for the year ended December 31, 1994 was $378,878, including
license revenues from a third party and development revenues from Physicians'
Online, Inc. See "Certain Transactions." The Company realized no revenue during
the period from inception through December 31, 1993. During both of such
periods, the Company was a development stage company primarily engaged in the
development of clinical information systems.
 
    Operating expenses for the year ended December 31, 1994 increased to $1.3
million, from $66,192 in the period from inception to December 31, 1993. The
increase in operating expenses was due, in part, to the inclusion of 12 months
of operating results in 1994 compared with approximately four months in 1993
and, in part, to the increase in staffing expenses and general corporate
expenses required to further develop the Company's clinical information systems.
 
    Research and development expenses for the year ended December 31, 1994
increased to $1.6 million from $454,622 for the period from inception to
December 31, 1993. These expenses related to the Company's development
activities for its clinical information systems.
 
    The net loss for the year ended December 31, 1994 was $2.5 million compared
to a loss of $520,814 for the period from inception through December 31, 1993.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has historically financed its capital requirements through the
sale of equity and debt securities. The Company issued three 8% promissory notes
in the principal amounts of $1.5 million, $750,000 and $750,000 on February 28,
April 26 and June 28, 1996, respectively. The Company issued six 9% promissory
notes in the aggregate principal amount of $2.0 million on June 19 and August
13, 1996. All of such notes will mature on the earlier of the consummation of
this offering and the one-year anniversary of their issuance, in the case of the
8% notes, or July 31, 1997, in the case of the 9% notes. The proceeds of such
notes are being used to finance working capital. At June 30, 1996, the Company
had cash and cash equivalents of $836,863.
 
    For the year ended December 31, 1995, the Company had a negative cash flow
from its operating activities of $4.3 million, compared with $4.1 million for
the six months ended June 30, 1996. Net cash used in investing activities was
$1.0 million for the year ended December 31, 1995 and principally related to
purchases of property, plant and equipment. Net cash provided by financing
activities was $6.8 million for the year ended December 31, 1995 and related to
the private placement of equity
 
                                       24
<PAGE>
securities. See "Certain Transactions." Net cash provided by financing
activities for the six months ended June 30, 1996 was $3.7 million, principally
attributable to the above-described debt issuances.
 
    The Company's operating plan for the remainder of 1996 and for the first two
quarters of 1997 includes continued development of the Company's integrated
management services and clinical information systems. The principal categories
of expenditures include research and development of the Company's clinical
information systems as well as ongoing business development and marketing. The
Company believes that the net proceeds of this offering, cash on hand, interest
income and revenues from operations will be sufficient to fund planned
operations of the Company through at least the end of 1998. The Company has no
planned material capital expenditures or capital commitments. See "Risk Factors
- -- Limited Operating History; History of Losses; Uncertainty of Future
Profitability."
 
    From time to time in the ordinary course of its business, the Company
evaluates possible acquisitions of businesses, products and technologies that
are complementary to those of the Company. The Company currently has no
agreements or understandings, and is not engaged in active negotiations, with
respect to any such acquisition.
 
   
    Under certain specified circumstances, the Company has the option to cause
the Roll Up Transaction to occur. The Company has reserved 548,224 shares of
Common Stock for issuance upon consummation of the Roll Up Transaction, all of
which will be issued if the Company effects the Roll Up Transaction.
Accordingly, the Roll Up Transaction, if effected, will be dilutive to
investors. In addition, certain of the physician groups and networks managed by
the Company have rights to require the Company to purchase all or part of such
physicians' interest in their respective MSO in the event that the Company does
not consummate the Roll Up Transaction within one year after the satisfaction of
specified conditions. There can be no assurance that the Company will have the
financial resources to purchase such interests in accordance with its
obligations at the time any such rights are exercised, or that the Company would
be able to obtain financing on satisfactory terms or conditions, if at all, to
purchase such interests. In addition, pursuant to its agreement with one of its
physician group practice clients, the Company has agreed, under certain
circumstances, to advance funds to such group practice to finance working
capital. To date, the Company has not made any advances to such group practice
under the agreement and it does not expect to do so in the future. See
"Business--Contractual Relationships with Affiliated Physicians."

OVERVIEW
 
    Advanced Health Corporation provides a full range of integrated management
services and clinical information systems to physician group practices, single
legal entities comprised of multiple physicians, and physician networks,
aggregations of individual physicians and physician groups formed for the
purpose of entering into contracts with third-party payors. The management
services provided by the Company include physician practice and network
development, marketing, payor contracting, financial and administrative
management, clinical information management, human resource management and
practice and network governance. The Company developed its clinical information
systems to provide physicians, at the point of care and on a real-time basis,
with patient-specific clinical and payor information and the ability to generate
patient medical orders and facilitate the implementation of disease management
programs. Through the management of multi-specialty and single-specialty
physician group practices and networks, the Company focuses its management
efforts on high-cost, high-volume disease specialties, such as cardiology,
oncology and orthopedics. The Company currently manages two multi-specialty
physician group practices and two single-specialty physician group practices
comprised of more than 75 physicians in the New York metropolitan area and eight
physician networks with approximately 800 physicians in the greater New York and
Atlanta metropolitan areas, and provides physician group consulting services to
more than 100 physicians. The Company believes its management services and
clinical information systems will enable physicians to enhance the quality and
reduce the cost of health care.
 
INDUSTRY
 
    Health care expenditures in the United States have risen rapidly over the
past two decades and totalled approximately $1 trillion in 1994. One significant
factor affecting health care expenditures in the United States is the aging of
the population. Older Americans utilize more health care services. In 1992, the
number of Americans 65 years old or over represented 12% of the U.S. population,
but were responsible for approximately 23% of all health care expenditures. In
particular, older Americans spend more on certain medical specialties, such as
cardiology, oncology and orthopedics. In 1992, spending on cardiology, oncology
and orthopedics totalled approximately $200 billion and represented
approximately 17%, 5% and 5%, respectively, of total direct health care costs in
the United States.
 
    Increasing concern over the rising cost of health care in the United States
has led to the development of managed care organizations and programs. Under
such programs, managed care payors typically govern the provision of health care
with the objective of ensuring delivery of quality care in a cost-effective
manner. The traditional fee-for-service method of compensating health care
providers offers few incentives for the efficient utilization of resources and
is generally believed to contribute to health care cost increases at rates
significantly higher than inflation. Consequently, fee-for-service reimbursement
is rapidly being replaced by alternative reimbursement models, including
capitated and other fixed-fee arrangements. The number of private insurance
beneficiaries who are enrolled in HMOs increased by approximately 45% from 1991
to 1995, with approximately 40 million beneficiaries enrolled in HMOs in 1991
and approximately 58 million beneficiaries enrolled in HMOs in 1995. In
addition, the number of Medicare beneficiaries enrolled in managed care programs
increased by approximately 52% from December 1994 to April 1996. The growth in
enrollment in these new reimbursement models is shifting the financial risk of
delivering health care from payors to providers.
 
    As a result of this changing health care environment, health care cost
containment pressures have increased physician management responsibilities while
lowering reimbursement rates to physicians. Consequently, physician compensation
has declined; the average net income for physicians decreased by approximately
4% from 1993 to 1994. Because approximately 67% of all physicians currently
practice individually or in two-person groups, their ability to lower costs and
to negotiate with payors is limited. Individual physicians and small group
practices also tend to have limited administrative capacity, limited ties to
other health care providers (restricting their ability to coordinate care across
a variety of
 
                                       26
<PAGE>
specialties), limited capital to invest in new clinical equipment and
technologies and limited purchasing power with vendors of medical supplies. In
addition, individual physicians and small group practices typically lack the
information systems necessary to enter into and manage risk-sharing contracts
with payors and to implement disease management programs efficiently.
 
    In response to the foregoing factors, individual physicians and small group
practices are increasingly affiliating with larger group practices and physician
practice management companies ("PPMs"). From 1991 to 1995, the number of
physicians practicing in group practices increased by approximately 14% to a
total of 185,000 physicians, with approximately 5% of such physicians managed by
PPMs. By acquiring physician practices, PPMs are successfully providing
physicians with lower administrative costs, leverage with vendors and payors and
economies of scale necessary to attract capital resources. In addition,
management companies and consultants are organizing independent physician
practices, independent physician associations, physician hospital organizations
and other physician organizations for the purpose of enabling physicians to
contract with managed care payors.
 
    The Company believes that significant opportunities exist, in the
consolidating health care industry, to assist physicians in managing the
administrative aspects of group practices and networks. More importantly, since
clinical decisions made by physicians impact 85% of overall health care
expenditures, the Company believes that even greater opportunities exist to
assist physicians in managing the clinical aspects of group practices and
networks. The Company believes its integrated physician practice and network
management services and clinical information systems will enable physicians to
more effectively control both the quality and cost of health care.
 
STRATEGY
 
    The objective of the Company is to become a leading provider of integrated
management services and clinical information systems to physician organizations.
By enabling physicians to develop and efficiently manage group practices and
networks, the Company seeks to assist physicians in facilitating risk-based
managed care contracts, developing and implementing disease management programs
and monitoring and controlling health care outcomes and costs. The Company
intends to achieve its objective through the implementation of the following
strategy:
 
 .Establishing Long-Term Alliances with Physician Organizations. The Company is
 seeking to partner with physician group practices and networks through
 long-term management contracts under which the Company provides a full range of
 integrated management and information services. The Company believes that
 contracting with physician organizations, rather than acquiring them, permits
 physicians to remain independent while providing them with the proper
 incentives and resources to improve their organizations. The Company typically
 develops an alliance with each physician organization through the establishment
 of an MSO. See "Business -- Contractual Relationships with Affiliated
 Physicians."
 
 . Managing High-Cost, High-Volume Disease Specialties. The Company believes that
  the greatest opportunity for achieving clinical efficiencies is in high-cost,
  high-volume disease specialties such as cardiology, oncology and orthopedics.
  Total health care expenditures for these medical specialties are expected to
  increase with the aging of the U.S. population. The Company seeks to integrate
  physicians into multi-specialty and single-specialty practices and networks to
  provide them with greater access to managed care contracts and to implement
  disease management programs. The Company believes that the evolution of
  disease specialty treatment organizations will play a major role in managed
  care contracting as payors recognize that the quality of care is improved and
  the cost of care reduced when reimbursement and health care services target a
  specific disease through coordinated networks of health care providers.
 
 . Providing Physicians with Clinical Information at the Point of Care. The
  Company has designed and developed point-of-care clinical information systems
  that link physician users and their offices on a real-time basis to other
  physicians, health care providers and third-party databases. By facilitating
  the
 
                                       27
<PAGE>
  integration of clinical guidelines and efficient access to information, the
  Company believes it can assist physicians in improving the quality and
  lowering the cost of patient care.
 
 . Focusing on Selected Geographic Markets. The Company seeks to provide its
  services to physician group practices and networks located principally in
  geographic markets where fee-for-service reimbursement is shifting to
  capitated and other risk-based reimbursement and where there are significant
  concentrations of physicians specializing in high-cost, high-volume disease
  specialties. The Company's initial target markets include the greater New
  York, Philadelphia and Atlanta metropolitan areas.
 
 . Developing Strategic Industry Relationships. The Company believes that
  developing strategic industry relationships will enhance its ability to
  penetrate existing markets, gain access to new markets and develop new
  products and services. The Company has entered into a software license and
  integration agreement with Merck Medco Managed Care, Inc. for the Company's
  prescription writing software. In addition, the Company has entered into a
  contract with an affiliate of PCS Health Systems, Inc., the managed care unit
  of Eli Lilly & Company, to provide disease management information services and
  software for the treatment of certain diseases. The Company is continuing to
  seek relationships for the development and distribution to third parties of
  its clinical information systems.
 
    The Company intends to use the balance of the net proceeds of this offering
remaining after the repayment of certain indebtedness (see "Use of Proceeds") to
pursue its strategy. The Company's operating plan for the remainder of 1996 and
the first two quarters of 1997 includes continued development of the Company's
integrated management services and clinical information systems. The principal
categories of expenditures include research and development of the Company's
clinical information systems as well as ongoing business development and
marketing. The Company believes that the net proceeds of this offering, cash on
hand, interest income and revenues from operations will be sufficient to fund
planned operations of the Company through at least the end of 1998. The Company
has no planned material capital expenditures or capital commitments. See "Risk
Factors--Limited Operating History; History of Losses; Uncertainty of Future
Profitability."
 
PHYSICIAN PRACTICE AND NETWORK SERVICES
 
    The Company provides physicians with a full range of integrated services to
form and develop group practices and networks, to manage group practice and
network operations, to develop disease management programs and to manage medical
risk. These integrated services include clinical support and administrative and
marketing services as well as point-of-care information systems and support. The
Company often initially provides physician practice and network services
pursuant to a consulting arrangement. The Company believes that its
point-of-care clinical information systems provide physicians with the
information needed to improve the quality and reduce the cost of health care.
 
    The Company manages two multi-specialty group practices and two
single-specialty group practices located in the New York metropolitan area. The
two multi-specialty group practices are made up of more than 50 physicians who
have, with the Company's assistance, aggregated their practices into group
practices. The medical specialties represented by these two groups include adult
primary care, cardiology, oncology and orthopedics. The two single-specialty
group practices are collectively comprised of more than 25 clinical
cardiologists, interventional cardiologists and cardiothoracic surgeons,
including leading physicians in the areas of minimally invasive coronary artery
bypass grafts and angioplasties employing coronary stents. The Company is
currently negotiating the terms of management agreements with additional
physician group practices in the greater New York, Philadelphia and Atlanta
metropolitan areas.
 
    The Company currently provides physician group consulting services to more
than 100 physicians. Such services have traditionally included group formation
services. More recently, the Company has begun to provide operations development
and strategic planning services to established groups. The Company believes that
the provision of consulting services, particularly operations development and
 
                                       28
<PAGE>
strategic planning services, may lead to the establishment of long-term practice
management agreements.
 
    The Company manages eight physician networks covering approximately 738,000
lives, with a total of seven payor contracts among such networks. The Company
manages three networks consisting of approximately 225 cardiologists in New
Jersey, Pennsylvania and Delaware, and is developing additional cardiology
networks in New York and Connecticut. The Company anticipates that these
cardiovascular networks will provide comprehensive cardiac care, including
ancillary services. The Company manages a community and medical center-based
oncology network in Atlanta serving approximately 150,000 lives that includes
both medical and radiation oncology. The Company is currently developing an
oncology network in New Jersey. The Company manages an orthopedic network in
Atlanta, covering approximately 205,000 lives and is developing orthopedic
networks in New York, New Jersey, Pennsylvania and Connecticut. In addition, the
Company manages three additional networks in the greater Atlanta area covering
approximately 383,000 lives, including a multi-specialty network, an obstetrics
and gynecology network and a plastic surgery network.
 
    In addition to providing administrative management services to physician
organizations, the Company seeks to differentiate itself by assisting physicians
in managing the clinical aspects of their practices. The Company believes that
its integrated management services and clinical information systems will enhance
the ability of physician group practices and networks to implement disease
management programs and to manage practices under risk-based contracts. The
Company is working to assist physicians in developing disease-specific clinical
practice guidelines and in practicing in accordance with applicable standards of
care. The Company has initially focused the implementation of its
single-specialty disease management strategy on the creation of an integrated
comprehensive cardiovascular care program, which includes physician group
practices, networks and medical support services. It is anticipated that this
disease management program will be delivered through linked practices and
networks of cardiovascular specialists under management and/or development by
the Company who will provide integrated, high-quality care for patients based on
clinical care guidelines developed by the physician network. The Company
anticipates that the physicians within these practices and networks will be
linked together by the Company's clinical information systems.
 
    The Company has expanded its physician practice and network management
expertise through acquisitions. In August 1995, the Company acquired the assets
of Peltz, which provides consulting services to physicians seeking to form group
practices on the East Coast, including assistance in the legal, administrative,
technical, and logistical aspects of group formation and the subsequent
recruiting of new physicians. In September 1995, the Company acquired Health
Connections, an Atlanta-based physician network management company with over two
years of network management experience in disease-specific areas, including
oncology and orthopedics. In April 1996, the Company acquired certain assets of
Benenson, a physician network development company specializing in the formation
of state-wide and regional cardiology and orthopedic networks capable of
marketing and servicing risk-based contracts.
 
    The Company markets its physician practice management and network management
services through (i) direct sales methods, (ii) consultative sales that include
providing advice on the development, consolidation and financing of group
practices and networks and (iii) cross-selling to customers of its clinical
information systems.

CLINICAL INFORMATION SYSTEMS
 
    The Company has developed clinical information systems that link physician
users at the point of care and on a real-time basis with patient data and
clinical guidelines maintained by the Company and third parties. The Company's
clinical information systems consist of proprietary software, third-party
hardware, proprietary and third-party databases and related support services.
The Company's clinical information systems are designed to allow physicians (i)
to access patient-specific clinical and payor information, (ii) to generate
patient instructions, prescriptions and orders for tests, specialty referrals
and specialty procedures and (iii) to access databases containing managed care
and disease management guidelines, diagnostic/treatment preferences and
guidelines affecting medical orders.
 
    The Company's clinical information systems are designed to complement
existing health care information systems and to function with third-party
applications. The clinical information system connects to physician users either
through the use of a hand-held computer equipped with a wireless modem or a
desktop computer using a standard wireline modem. It is anticipated that access
to the Company's clinical information systems will be delivered to physician
users and other health care professionals via both private and public networks,
including the Internet. The Company's product suites operate within a
client/server-based open architecture. The Company's products support HL-7
interfaces, incorporate TCP/IP protocols for real-time data transmission and run
on the Microsoft Windows operating system and standard hardware platforms. The
Company employs proprietary processes and standard commercial security measures
to ensure the privacy of the data communication paths within its products.
 
    The Company has made only limited commercial sales of its clinical
information systems to date. Since October 1994, the Company has provided its
clinical information systems, including user support, data center operations and
network operations, to two pilot sites in Michigan, consisting of approximately
10 physicians and, since December 1995, to a multi-specialty group, consisting
of approximately 35 physicians, that the Company manages in New York. The
Company has developed training and installation templates for its products and
has experience using these templates in its two pilot sites and in a New
York-based physician group practice. The Company has a contract with a
third-party to provide training to its clients. In addition to providing its
clinical information systems to its affiliated physicians, the Company intends
to continue licensing its clinical information systems to third-party health
care organizations. The Company has one employee dedicated to developing
distribution
 
                                       31
<PAGE>
channels for its clinical information systems. In addition, the Company markets
its clinical information systems to physician group practices and networks
together with its management services.
 
    On September 27, 1995, the Company entered into a software license and
integration agreement with Merck Medco Managed Care, Inc. for the Company's
prescription writing software, which provides formulary management, drug
utilization and review ("DUR") edits and linkage to drug therapy protocols. On
August 1, 1995, the Company signed an agreement to provide disease management
information systems and software to an affiliate of PCS Health Systems, Inc.,
the managed care unit of Eli Lilly & Company. The Eli Lilly & Company affiliate
has agreed to sponsor two pilot programs involving the software applications
developed by the Company.
 
    The Company continues to pursue strategic relationships with health care
providers as well as hospital information systems companies, physician practice
management systems companies and on-line services companies for the purpose of
further developing and marketing its information systems.
 
  SYSTEMS
 
    The Company offers a broad range of clinical information systems for
physician users through two suites of applications, Med-E-Practice and
Med-E-Network. Med-E-Practice is designed to be used directly by physician group
practices in support of clinical decision making, clinical ordering and
administrative management. Med-E-Network is designed to support administrative
and clinical decision making for physician networks engaged in capitated and
other fixed-fee arrangements under managed care contracts. These systems have
only been developed by the Company recently, and the initial limited commercial
installations of the Med-E-Practice suite of applications occurred in June 1996.
The Med-E-Network suite of applications is expected to be initially installed
during the fourth quarter of 1996. See "Risk Factors -- Uncertainty of
Successful Commercialization of Clinical Information Systems."
 
    The following table summarizes the two suites of applications offered and
being developed by the Company:

    Med-E-Practice provides administrative and clinical support for physician
group practices. The Med-E-Practice suite is designed for use by physicians at
the point of care and on a real-time basis and is intended to allow better care
decisions by providing better information. All of the applications in the
Med-E-Practice suite are designed to be run on a pen-based, portable, wireless
computer for use in a busy ambulatory practice. The Med-E-Practice suite
consists of the following applications:
 
    Smart Scripts. Smart Scripts is a prescription writing application that
provides the clinician: (i) patient-specific prescription history, (ii)
real-time formulary management, specific to each patient's insurance coverage,
(iii) clinical intervention screening, using third-party DUR modules, (iv)
default dosing, (v) generic substitution, (vi) condition/drug relationship
maintenance and (vii) support for individual customer lists. The Company also
markets Smart Scripts as a stand-alone product. The Company is also developing
an Internet/intranet version of Smart Scripts, "Internet Script Writer."
Internet Script Writer is designed to allow any physician with access to the
Internet to gain the advantages of on-line prescription management. The Internet
Script Writer will provide (i) patient-specific prescription history, (ii)
real-time formulary management, specific to each patient's insurance coverage,
(iii) clinical intervention screening, using third-party DUR modules and (iv)
legible, printed prescriptions. The Company expects that the Internet Script
Writer will be commercially available in the fourth quarter of 1996.
 
    Med-E-Visit. Med-E-Visit is a patient encounter management application that
records procedures and conditions. Med-E-Visit allows for the selection of
laboratory, x-ray, immunization, visit and procedure codes, using standard
diagnostic and billing coding. Med-E-Visit links all procedures with conditions
for outcomes analysis and facilitates correct insurance billing. Med-E-Visit
records follow-up visit requirements and, in conjunction with the Practice
Management Integrator, submits a Superbill to a third-party practice management
system.
 
    Referral. The Referral application simplifies patient referrals through
real-time access to each individual patient's appropriate physician network. The
Referral application records referral information, provides network-specific
referral rules and helps to select the appropriate referral physician by
specialty and location and allows a complete referral form to be created and
printed.
 
    Conditions Editor. The Conditions Editor automatically tracks a patient's
medical condition information generated by the other applications in the
Med-E-Practice suite. It uses disease-specific algorithms to monitor and permit
a physician to record a patient encounter. The Conditions Editor also allows the
clinical user to directly edit and manage the current conditions list.
 
    Allergies Editor. The Allergies Editor allows the clinical user to easily
maintain allergy information for use in the Med-E-Practice suite. Allergy
information is provided by the Conditions Editor to the Smart Scripts
application and other Med-E-Practice applications.
 
    Practice Management Integrator. The Practice Management Integrator
integrates the Med-E-Practice suite with third-party practice management systems
through a Company-designed interface using the industry standard HL-7 interface.
 
    Clinical Note. The Clinical Note is designed to be an "at a glance" utility
bringing the most appropriate information to the physician at the point of care.
The Clinical Note application is intended to enable the physician to review the
most current information regarding the patient's medical history, including
current medications, active and inactive conditions, office visits, past
referrals and pertinent test results. The Clinical Note also permits the
physician to update patient information during the patient encounter with new
clinical findings, new prescriptions, new referrals and new procedure orders.
The automated Clinical Note application structures the input of information and
orders in a focused and customizable format to allow rapid physician-driven data
entry and retrieval. The Clinical Note is expected to be commercially available
in 1997.
 
                                       33

    Med-E-Network is a suite of network management applications supporting
physician networks engaged in risk-based contracts with payors. Med-E-Network
automates network configuration, maintenance of network rules, referral
management, utilization review management, claims and encounter submissions and
financial and clinical reporting. Med-E-Network utilizes a relational database
engine which integrates various sources of information and provides a flexible
repository for developing administrative, financial and clinical reports. The
Med-E-Network suite consists of the following applications:
 
    Med-E-Net Central. Med-E-Net Central is designed to centralize and support
the administrative functions of a risk-taking physician network by (i) providing
pre-certification, (ii) processing claims and encounters, (iii) generating,
managing and matching referrals, (iv) providing financial and clinical
utilization review reporting, (v) providing automated utilization review
approvals and denials and (vi) providing eligibility assistance.
 
    Med-E-Net Office. Med-E-Net Office links physician offices to Med-E-Net
Central. Med-E-Net Office is a forms-based, scaleable, client/server application
supporting referral creation and receipt, claims and encounter submission and
the creation and submission of treatment plans.
 
    Med-E-Net Integrator. The Med-E-Net Integrator provides connectivity between
the applications in the Med-E-Network suite and third-party databases.
 
    Med-E-Net Cardiology. Med-E-Net Cardiology is designed to deliver
procedure-specific guidelines for the management of cardiac disease coupled with
an automated procedure approval and referral engine. Med-E-Net Cardiology is
expected to be commercially available in the third quarter of 1996.
 
  CLINICAL INFORMATION SYSTEMS DEVELOPMENT
 
    The Company believes that the timely development of new clinical information
applications and the enhancement of existing clinical information systems are
important to its competitive position. The Company's product development
strategy is directed toward creating new applications that (i) increase the
functionality of current products by providing enhanced interfaces to
third-party systems and data repositories, (ii) expand coverage along the
continuum of clinical care, (iii) increase coverage to additional disease and
procedure groups and (iv) provide customers with a range of decision support
systems at various price points. The Company has approximately 20 professionals
dedicated to systems development. See "Risk Factors -- Technological Change."
 
CONTRACTUAL RELATIONSHIPS WITH AFFILIATED PHYSICIANS
 
    The Company typically establishes an MSO for each physician organization it
manages. The MSO is a joint venture between the physician organization and the
Company, with the Company owning at least 51% of the equity in the MSO. The MSO
enters into a long-term management services agreement with the physician
organization pursuant to which the MSO provides group practice management or
network management services that provide both administrative and clinical
support to members of the physician organization. The MSO concurrently enters
into a services agreement with the Company pursuant to which it gains access to
management services and clinical information systems from the Company. The MSO's
assets consist primarily of its management service contracts with the physician
group or network served and its liabilities consist primarily of its obligations
under its agreement with the Company and its obligations to its employees. For
certain MSOs, a stockholders agreement is entered into among the MSO, the
physician organization and the Company. The stockholders agreement, among other
things, (i) restricts the transfer of MSO equity, (ii) provides the terms upon
which, after the occurrence of the Trigger Event (as hereinafter defined), the
MSO can, at the Company's option, be merged with and into a wholly-owned
subsidiary of the Company in the Roll Up Transaction and (iii) grants to the
physician organization the right to put its equity in the MSO to the Company at
a price equal to 110% of the then-current fair market value of the shares of
Common Stock that would have otherwise been issued in the Roll Up Transaction if
the Company does not exercise its option to
 
                                       34
<PAGE>
cause the Roll Up Transaction to occur within one year after the occurrence of
the Trigger Event. In the case of each such MSO, a Trigger Event will occur at
such time as (i) the Company is providing physician practice management services
to at least 300 physicians, (ii) the Company is providing physician network
management services to at least 2,000 physicians, (iii) the Company has at least
$75,000,000 in stockholders' equity and (iv) the Company's Common Stock is
publicly traded. As of August 31, 1996, the Company was providing (i) physician
practice management services to 77 physicians and (ii) physician network
management services to 798 physicians and as of June 30, 1996, the Company had
$863,349 in stockholders' equity. The Company has reserved 548,224 shares of
Common Stock for issuance upon the merger of such MSOs into the Company. See
"Risk Factors -- Management Service Organizations Not Wholly-Owned; Physician
Put Rights; Dilution."
 
    Physician Practices. The management services agreements between the MSO and
a physician practice group generally have an initial term of five to 20 years
and are automatically renewable for additional terms. Such agreements typically
are subject to early termination for cause. The management services agreements
generally obligate an MSO to provide certain non-medical practice management
services to the physician practice group for a monthly fee. The fee paid to the
MSO is generally a combination of fixed fees for certain services and percentage
fees for certain services. For risk-based contracts that the physician practice
group enters into, the management services agreement will generally provide for
additional management fees based upon savings recognized by the physician
practice group because of any cost efficiencies resulting from the MSO's
performance. The fees are set to be competitive within the geographic area in
which the physician practice group is located. A provision restricting the
physician practice group from competing against the MSO or employing the MSO's
employees is generally included in the agreement.
 
    Physician Networks. The management services agreements between the MSO and a
physician network generally have an initial term of at least five years and are
automatically renewable for additional terms. Such agreements typically are
subject to early termination for cause. The management services agreements
generally obligate an MSO to provide certain non-medical practice management
services to the physician network for a fee. The fee paid to the MSO for
risk-based or capitated contracts is generally a service fee equal to the actual
cost, not to exceed a specified percentage of capitated revenues, for providing
the non-medical management services plus an incentive based on savings generated
by the network. The fee paid to the MSO for fee-for-service contracts is
generally equal to the administrative fees included in the managed care contract
plus a management processing fee agreed upon by the MSO and the physician
network. The fees are set to be competitive within the geographic area in which
the physician network is located. In the agreement, the physician network agrees
that the MSO will be the exclusive provider of non-medical management services
to the physician network.
 
   
    Capitated and Other Fixed-Fee Arrangements. The Company anticipates entering
into managed care or capitated arrangements, either indirectly through the
assignment of managed care contracts entered into between its affiliated
physicians and third-party payors or directly through the formation of an IPA.
See "Government Regulation -- Insurance Regulations." The Company has little
experience in managing capitated-risk arrangements and has no experience in
forming or managing an IPA. Revenues under any managed care or capitated
arrangements entered into by the Company, whether through the assignment of a
capitated contract entered into by its affiliated physicians or directly through
an IPA, will generally be a fixed amount per enrollee. Under such an
arrangement, the Company would contract with affiliated physicians for the
provision of health care services and the Company would be responsible for the
provision of all or a portion of the health care requirements of such enrollees.
To the extent that enrollees require more care than is anticipated by the
Company upon entering into such a contract, the Company's revenues under such
contracts may be insufficient to cover its costs. The Company expects to enter
into reinsurance agreements with third-party insurers in respect of a portion of
such risk.
    

                                       35

PROPRIETARY RIGHTS
 
    The Company is relying upon the effectiveness of protection provided by a
combination of patent, trade secret and copyright laws, nondisclosure and other
contractual provisions and technological measures to protect its proprietary
position in its methodologies, databases and software. The Company has two U.S.
patent applications and a foreign patent application commensurate with both U.S.
applications, but no issued patents. The patent applications are directed to the
Company's Smart Scripts prescription management system and related technologies.
No assurance can be provided that a patent or patents will be issued or will
provide the Company with adequate protection. Nor can any assurance be given
that patent, trade secret, copyright or other intellectual property rights can
be successfully asserted in any court action. The Company has also filed
applications for registration of copyrights in its software, user documentation
and databases. The copyright protection accorded to databases, however, is
fairly limited. While the arrangement and selection of data are protectable, the
actual data are not, and others are free to create databases that perform the
same function. The Company distributes its clinical information systems products
under agreements that grant customers non-exclusive licenses and generally
contain terms and conditions restricting the disclosure and use of the Company's
systems. In addition, the Company attempts to protect the secrecy of its
proprietary databases and other trade secrets and proprietary information
through confidentiality agreements with employees, consultants and third
parties.
 
    The Company believes that, aside from the various legal protections of its
proprietary information and technologies, factors such as the technological and
creative skills of its personnel and product maintenance and support are
integral to establishing and maintaining its position within the health care
industry. Although the Company believes that its products do not infringe upon
the proprietary rights of third parties, there can be no assurance that third
parties will not assert infringement claims against the Company in the future.
See "Risk Factors -- Dependence on Proprietary Assets."
 
COMPETITION
 
    The provision of physician practice and network management services is a
highly competitive business in which the Company competes for contracts with
several national and many regional and local companies. The Company also
competes with traditional managers of health care services that directly recruit
and manage physicians. In addition, certain of the Company's competitors are
dedicated to or specialize in the management of single-specialty practices
focused on diseases such as cardiology, oncology and orthopedics, specialties on
which the Company intends to focus. Certain of the Company's competitors have
access to substantially greater financial resources than the Company. The
Company believes that competition in this industry is generally based on cost
and quality of services.
 
    The market for health care information systems and services is highly
competitive and rapidly changing. The Company believes that the principal
competitive factors for clinical information systems are the proprietary nature
of methodologies, databases and technical resources, the usefulness of the data
and reports generated by the software, customer service and support,
compatibility with the customer's existing information systems, potential for
product enhancement, vendor reputation, price and the effectiveness of marketing
and sales efforts.
 
    The Company's competitors include other providers of clinical information
systems and practice management systems. Many of the Company's competitors and
potential competitors have greater financial, product development, technical and
marketing resources than the Company, and currently have, or may develop or
acquire, substantial installed customer bases in the health care industry. In
addition, as the market for clinical information systems and practice management
systems develops, additional competitors may enter the market and competition
may intensify. While the Company believes that it will successfully
differentiate its clinical information systems from those of its competitors,
there can be no assurance that future competition will not have a material
adverse effect on the Company.
 
                                       36
<PAGE>
GOVERNMENT REGULATION
 
    As a participant in the health care industry, the Company's operations and
relationships are subject to extensive and increasing regulation by a number of
governmental entities at the federal, state, and local levels. The Company
believes its operations are in material compliance with applicable laws.
Nevertheless, because of the nature of the Company's relationship with physician
organizations, many aspects of the Company's business operations have not been
the subject of state or federal regulatory interpretations and there can be no
assurance that a review by courts or regulatory authorities of the Company's
business or that of its affiliated physician organizations will not result in a
determination that could adversely affect the operations of the Company or that
the health care regulatory environment will not change so as to restrict the
Company's or the affiliated physicians' existing operations or their expansion.
 
   
    Reimbursement. During the first six months of 1996, approximately 35% of the
revenues of the Company's affiliated physician group practices was derived from
payments made by government-sponsored health care programs (principally,
Medicare, Medicaid and state reimbursed programs). As a result, any change in
reimbursement regulations, policies, practices, interpretations or statutes
could adversely affect the operations of the Company. The federal Medicare
program adopted a system of reimbursement of physician services, RBRVS, which
took effect in 1992 and is expected to be fully implemented by December 31,
1996. The Company expects that the RBRVS fee schedule and other future changes
in Medicare reimbursement will result in some cases in a reduction and in some
cases in an increase from historical levels in the per-patient Medicare revenue
received by certain of the physician organizations with which the Company
contracts. Although the Company does not believe such reductions will have a
material adverse effect on the Company's operating results, the RBRVS fee
schedule may be adopted by other payors, which could have a material adverse
effect on the Company. See "Risk Factors -- Cost Containment and Reimbursement
Trends."
    
 
   
    Billing. There are also state and federal civil and criminal statutes
imposing substantial penalties, including civil and criminal fines and
imprisonment, on health care providers that fraudulently or wrongfully bill
governmental or other third-party payors for health care services. The federal
law prohibiting false billings allows a private person to bring a civil action
in the name of the U.S. government for violations of its provisions. The Company
believes it is in material compliance with such laws, but there is no assurance
that the Company's activities will not be challenged or scrutinized by
governmental authorities. Moreover, technical Medicare and other reimbursement
rules affect the structure of physician billing arrangements. The Company
believes it is in material compliance with such regulations, but regulatory
authorities may differ and in such event the Company may have to modify its
relationship with physician organizations. Noncompliance with such regulations
may adversely affect the business, financial condition and results of operations
of the Company and subject it and affiliated physician groups to penalties and
additional costs.
    
 
   
    Corporate Practice of Medicine. The laws of many states prohibit business
corporations such as the Company from practicing medicine and employing
physicians to practice medicine. These laws forbid both direct control over
medical decisions and indirect interference such as splitting medical fees with
physicians or controlling budgetary allotments for patient care. Laws regarding
the corporate practice of medicine vary from state to state and are enforced by
the courts and by regulatory authorities. New York State, for example, prohibits
percentage payments from physicians or physician groups to management entities
for services other than billing and collecting and prohibits management entities
from engaging in the delivery of medical services. All of the management service
agreements ("MSAs") between the Company's majority-owned MSOs and the physician
groups and networks they serve specifically address this issue. First, each
explicitly provides that the physician organization retains complete control
over medical decisionmaking, and that the MSO may neither interfere with the
professional judgment of medical personnel nor control, direct or supervise the
provision of medical services. Furthermore, the MSAs make it clear that the MSO
may not perform any services or activities which constitute the practice of
medicine. For instance, the MSO has no responsibility in decisions
    
 
                                       37
<PAGE>
   
regarding level of patient care, credentialing or quality monitoring.
Administrative policies, budgets and fee schedules affecting the delivery of
medical services are developed by a Joint Management Advisory Board, which is at
all times controlled by medical group physicians. In contrast, each MSO
controlled by the Company is a management organization whose role is to assist
with and coordinate administrative functions and to advise the physician group
as to the relationship between its performance of medical activities and the
administrative and business functioning of its practice. The Company believes it
is in material compliance with regulations regarding the corporate practice of
medicine, but regulatory authority may differ and in such event expansion of the
operations of the Company to certain jurisdictions may require it to comply with
such jurisdictions' regulations which could lead to structural and
organizational modifications of the Company's form of relationships with
physician organizations. Such changes, if any, could have a material adverse
effect on the Company.
    
 
   
    Anti-Kickback Statutes. Certain provisions of the Social Security Act,
commonly referred to as the "Anti-kickback Statute," prohibit the offer,
payment, solicitation or receipt of any form of remuneration in return for the
referral of Medicare or state health program patients or patient care
opportunities, or in return for the recommendation, arrangement, purchase, lease
or order of items or services that are covered by Medicare or state health
programs. The Anti-kickback Statute is broad in scope and has been broadly
interpreted by courts in many jurisdictions. Read literally, the statute places
at risk many legitimate business arrangements, potentially subjecting such
arrangements to lengthy, expensive investigations and prosecutions initiated by
federal and state governmental officials. Many states, including those in which
the Company does business, have adopted similar prohibitions against payments
intended to induce referrals of Medicaid and other third-party payor patients.
The Company believes that, although it is receiving remuneration under the
management services agreements for management services, it is not in a position
to make or influence the referral of patients or services reimbursed under
government programs to the physician groups and, therefore, believes it has not
violated the Anti-kickback Statute. The Company also is not a separate provider
of Medicare or state health program reimbursed services. To the extent the
Company is deemed to be either a referral source or a separate provider under
its management services agreements and to receive referrals from physicians, the
financial arrangements under such agreements could be subject to scrutiny and
prosecution under the Anti-kickback Statute. Violation of the Anti-kickback
Statute is a felony, punishable by fines up to $25,000 per violation and
imprisonment for up to five years. In addition, the Department of Health and
Human Services may impose civil penalties excluding violators from participation
in Medicare or state health programs.
    
 
    In July 1991, in part to address concerns regarding the Anti-kickback
Statute, the federal government published regulations that provide exceptions,
or "safe harbors," for transactions that will be deemed not to violate the
Anti-kickback Statute. Among the safe harbors included in the regulations were
provisions relating to the sale of practitioner practices, management and
personal services agreements and employee relationships. Additional safe harbors
were published in September 1993 offering new protections under the
Anti-kickback Statute to eight activities, including referrals within group
practices consisting of active investors. Proposed amendments to clarify these
safe harbors were published in July 1994 which, if adopted, would cause
substantive retroactive changes to the 1991 regulations. Although the Company
believes that it is not in violation of the Anti-kickback Statute, its
operations may not fit within any of the existing or proposed safe harbors.
 
    Significant prohibitions against physician referrals were enacted by
Congress in the Omnibus Budget Reconciliation Act of 1993. These prohibitions,
commonly known as "Stark II," amended prior physician self-referral legislation
known as "Stark I" by dramatically enlarging the field of physician-owned or
physician-interested entities to which the referral prohibitions apply.
Effective January 1, 1995, Stark II prohibits, subject to certain exemptions, a
physician or a member of his immediate family from referring Medicare patients
to an entity providing "designated health services" in which the physician has
an ownership or investment interest, or with which the physician has entered
into a compensation arrangement including the physician's own group practice.
The designated health services
 
                                       38
<PAGE>
include radiology and other diagnostic services, radiation therapy services,
physical and occupational therapy services, durable medical equipment,
parenteral and enteral nutrients, equipment and supplies, prosthetics,
orthotics, outpatient prescription drugs, home health services and inpatient and
outpatient hospital services. The penalties for violating Stark II include a
prohibition on payment by these government programs and civil penalties of as
much as $15,000 for each violative referral and $100,000 for participation in a
"circumvention scheme." The Company believes that its activities are not in
violation of Stark I or Stark II. However, the Stark legislation is broad and
ambiguous. Interpretative regulations clarifying the provisions of Stark II have
not been issued. While the Company believes it is in compliance with the Stark
legislation, future regulations could require the Company to modify the form of
its relationships with physician organizations. Moreover, the violation of Stark
I or II by the Company's affiliated physician organizations could result in
significant fines and loss or reimbursement which could materially adversely
affect the Company. Many states in which the Company conducts business have
enacted similar laws applicable to all services.
 
   
    PIP Regulations. The Health Care Finance Administration ("HCFA") has issued
final regulations (the "PIP regulations") covering the use of physician
incentive plans ("PIPs") by HMOs and other managed care contractors and
subcontractors ("Organizations"), potentially including the Company. Any
Organization that contracts with a physician group that places the individual
physician members of the group at substantial financial risk for the provision
of services (e.g., if a primary care group takes risk but subcontracts with a
specialty group to provide certain services) must satisfy certain disclosure,
survey and stop-loss requirements. Under the PIP regulations, payments of any
kind, direct or indirect, to induce providers to reduce or limit covered or
medically necessary services ("Prohibited Payments") are prohibited. Further,
where there are no Prohibited Payments but there is risk sharing among
participating providers related to utilization of services by their patients,
the regulations contain three groups of requirements: (i) requirements for
physician incentive plans that place physicians at "substantial financial risk;"
(ii) disclosure requirements for all Organizations with PIPs; and (iii)
requirements related to subcontracting arrangements. In the case of substantial
financial risk (defined in the regulations according to several methods, but
essentially risk in excess of 25% of the maximum payments anticipated under a
plan with less than 25,000 covered lives), Organizations must: (1) conduct
enrollee surveys; and (2) ensure that all providers have specified stop-loss
protection. The violation of the requirements of the PIP regulations may result
in a variety of sanctions, including suspension of enrollment of new Medicaid or
Medicare members, or a civil monetary penalty of $25,000 for each determination
of noncompliance. In addition, because of the increasing public concerns
regarding PIPs, the PIP regulations may become the model for the industry as a
whole. The new regulations could have an affect on the ability of the Company to
effectively reduce the costs of providing services, by limiting the amount of
risk that may be imposed upon physicians.
    
 
   
    Anti-Trust. Because the affiliated physician organizations remain separate
legal entities, they may be deemed competitors subject to a range of antitrust
laws which prohibit anti-competitive conduct, including price fixing, concerted
refusals to deal and division of market. The Company intends to comply with such
state and federal laws as may affect its development of integrated health care
delivery networks, but there can be no assurance that a review of the Company's
business by courts or regulatory authorities will not result in a determination
that could adversely affect the operation of the Company and its affiliated
physician groups.
    
 
   
    Insurance Regulations. Laws in all states regulate the business of insurance
and the operation of HMOs. Many states also regulate the establishment and
operation of networks of health care providers. There can be no assurance that
regulatory authorities of the states in which the Company operates would not
apply these laws to require licensure of the Company's operations as an insurer,
as an HMO or as a provider network. On August 10, 1995, the NAIC issued a report
opining that certain risk-transferring arrangements may entail the business of
insurance, to which state licensure laws apply, but that licensure laws would
not apply where an unlicensed entity contracts to assume "downstream risk" from
a duly licensed health insurer or HMO for health care provided to that carrier's
enrollees. The
    
 
                                       39
<PAGE>
   
NAIC's conclusions are not binding on the states. The Company does not now have
capitated contracts and will enter into such contracts only with licensed
insurance companies and HMOs, and only if allowed by state law. The Company
believes that it is in compliance with these laws in the states in which it does
business, but there can be no assurance that future interpretations of insurance
laws and health care network laws by the regulatory authorities in these states
or in the states into which the Company may expand will not require licensure or
a restructuring of some or all of the Company's operations.
    
 
   
    Health Care Reform. As a result of the continued escalation of health care
costs and the inability of many individuals to obtain health insurance, numerous
proposals have been or may be introduced in the U.S. Congress and state
legislatures relating to health care reform. There can be no assurance as to the
ultimate content, timing or effect of any health care reform legislation, nor is
it possible at this time to estimate the impact of potential legislation, which
may be material, on the Company.
    
 
   
    Confidentiality of Patient Records. The confidentiality of patient records
and the circumstances under which such records may be released is subject to
substantial regulation under state and federal laws and regulations. To protect
patient confidentiality, data entries to the Company's databases delete any
patient identifiers, including name, address, hospital and physician. The
Company believes that its procedures comply with the laws and regulations
regarding the collection of patient data in substantially all jurisdictions, but
regulations governing patient confidentiality rights are evolving rapidly and
are often difficult to apply. Additional legislation governing the dissemination
of medical record information has been proposed at both the state and federal
level. This legislation may require holders of such information to implement
security measures that may be of substantial cost to the Company. There can be
no assurance that changes to state or federal laws would not materially restrict
the ability of the Company to obtain patient information originating from
records.
    
 
   
    FDA Regulation. Certain products, including software applications, intended
for use in the diagnosis of disease or other conditions, or in the cure,
treatment, mitigation or prevention of disease, are subject to regulation by the
FDA under the Federal Food, Drug and Cosmetic Act of 1938, as amended (the
"FDCA"). The FDCA imposes substantial regulatory controls over the
manufacturing, testing, labeling, sale, distribution, marketing and promotion of
medical devices and other related activities. These regulatory controls can
include, for example, compliance with the following: manufacturer establishment
registration and device listing; current good manufacturing practices; FDA
clearance of a premarket notification submission or FDA approval of a premarket
approval application; medical device adverse event reporting; and general
prohibitions on misbranding and adulteration. Violations of the FDCA can result
in severe criminal and civil penalties, and other sanctions, including, but not
limited to, product seizure, recall, repair or refund orders, withdrawal or
denial of premarket notifications or premarket approval applications, denial or
suspension of government contracts, and injunctions against unlawful product
manufacture, labeling, promotion, and distribution or other activities.
    
 
    In its 1989 Draft Policy Statement, the FDA stated that it intended to
exempt certain clinical decision support software products from a number of
regulatory controls. Under the 1989 Draft Policy Statement, the FDA stated that
it intended to exempt decision support software products that involve "competent
human intervention before any impact on human health occurs (e.g., where
clinical judgment and experience can be used to check and interpret a system
output)" from the following controls: manufacturer establishment registration
and device listing, premarket notification, and compliance with the medical
device reporting and current good manufacturing practice regulations. In the
1989 Draft Policy Statement, the FDA stated that until it formally exempted
decision support software products from these requirements, manufacturers of
eligible decision support software products would to be required to comply with
those controls.
 
    Since issuing the 1989 Draft Policy Statement, the FDA has not issued a
final policy on this issue and has not formally exempted any products as
discussed in the 1989 Draft Policy Statement. The FDA
 
                                       40
<PAGE>
has referred to the 1989 Draft Policy Statement in official presentations
regarding software regulation and in decisions and opinions regarding the
regulatory status of various products. Over the last few years, however, the FDA
has stated that it intends to issue a new policy concerning computer products.
Under this new policy, exemptions from regulatory controls, if any, would be
based upon a product specific "risk factor" analysis. For purposes of this
analysis, the FDA has considered, among other things, the following: (i)
seriousness of the disease to be diagnosed or treated; (ii) time frame for use
of the information; (iii) concordance with accepted medical practice; (iv)
format of data and its presentation; (v) individualized versus aggregate patient
care recommendations; and (vi) clarity of algorithms used in the software. Given
the FDA's intent to issue a new policy concerning the regulation of computer
software, there can be no assurance as to the effect of such a policy, if any,
upon the regulatory status of the Company's products.
 
    The Company believes that its clinical information systems are not medical
devices under the FDCA and, thus, are not subject to the controls imposed on
manufacturers of medical devices and do not fall within the scope of the 1989
Draft Policy Statement. The Company further believes that to the extent that its
products are determined to be medical devices, they fall within the exemptions
for decision support systems provided by the 1989 Draft Policy Statement. The
Company has not taken action to comply with the requirements that would
otherwise apply if the Company's products were determined to be non-exempt
medical devices.
 
    There can be no assurance that the FDA will not make a request or take other
action to require the Company to comply with any or all current or future
controls applicable to medical devices under the FDCA. There can be no assurance
that, if such a request were made or other action were taken, the Company could
comply in a timely manner, if at all, or that any failure to comply would not
have a material adverse effect on the Company's business, financial condition or
results of operations, or that the Company would not be subjected to significant
penalties or other sanctions. There can be no assurance that the FDA will
continue to permit any or all of the exemptions provided in the 1989 Draft
Policy Statement, or in a new policy statement, if any, or that the FDA will
promulgate regulations formally implementing such exemptions. There can be no
assurance that the Company's current or future clinical information systems will
qualify for future exemptions, if any, nor can there be any assurance that any
future requirements will not have a material adverse effect on the Company's
business, financial condition or results of operations.
 
   
    The health care industry is subject to changing political, economic and
regulatory influences that may affect the procurement practices and operations
of health care industry participants. During the past several years, government
regulation of reimbursement rates in the United States health care industry has
increased. Lawmakers continue to propose programs to reform the United States
health care system, which may contain proposals to increase governmental
involvement in health care, lower reimbursement rates and otherwise change the
operating environment for the Company's customers. Health care industry
participants may react to these proposals by curtailing or deferring
investments, including investments in the Company's products. The Company cannot
predict what impact, if any, such factors may have on its business, financial
condition and results of operations or on the price of the Common Stock.
    
 
LEGAL PROCEEDINGS
 
    The Company is not a party to any litigation that would have a material
adverse effect on its business, results of operations or financial condition.
 
EMPLOYEES
 
    As of August 31, 1996, the Company had a total of approximately 160
employees, approximately 30 of whom were employed in the Company's information
systems subsidiary. None of the Company's employees is subject to a collective
bargaining agreement. The Company has never experienced a work stoppage and
believes that its employee relations are satisfactory.

for their service as members of the Board of Directors, although they are
reimbursed for certain expenses in connection with attendance at Board and
Committee meetings. Non-employee directors of the Company are eligible to
receive options under the Company's 1995 Stock Option Plan. See "Management --
Stock Plans."
 
LIMITATIONS ON DIRECTORS' AND OFFICERS' LIABILITY
 
    The Company's Certificate of Incorporation provides that directors of the
Company shall not be personally liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director except for liability
(i) for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) in respect of
certain unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the DGCL or (iv) for any transaction
from which the director derived an improper personal benefit. The effect of
these provisions will be to eliminate the rights of the Company and its
stockholders (through stockholders' derivative suits on behalf of the Company)
to recover monetary damages against a director for breach of fiduciary duty as a
director (including breaches resulting from grossly negligent behavior), except
in the situations described above. These provisions will not limit the liability
of directors under federal securities laws.
 
    The Company's Certificate of Incorporation provides that the Company shall
indemnify its directors, officers, employees and agents to the fullest extent
permitted by law. The Company's Certificate of Incorporation also permits it to
secure insurance on behalf of any director, officer, employee or agent against
any expense, liability or loss arising out of his or her actions in such
capacity.
 
    The Company intends to obtain directors' and officers' liability insurance
("D&O Insurance") prior to the date of this Prospectus, and expects to continue
to carry D&O Insurance following this offering. In addition, the Company has
entered into an indemnification agreement with each of its directors and
officers under which the Company has indemnified each of them against expenses
and losses incurred for claims brought against them by reason of a director or
officer of the Company.
 
    The Company believes that the limitation of liability and indemnification
provisions in its Certificate of Incorporation, the D&O Insurance and the
indemnification agreements will enhance the Company's ability to continue to
attract and retain qualified individuals to serve as directors and officers.
There is no pending litigation or proceeding involving a director, officer or
employee of the Company to which the indemnification provisions would apply.
 
EXECUTIVE COMPENSATION
 
    The following table sets forth a summary of the compensation earned by the
Company's Chief Executive Officer and the other executive officers of the
Company whose combined salary and bonus for the year ended December 31, 1995 was
in excess of $100,000 (collectively, the "Named Executive Officers") for
services rendered in all capacities to the Company during the Company's fiscal

    reflected in this table may not necessarily be achieved.
(2) All options granted to Mr. Kaplan terminated upon the termination of his
    employment with the Company.
(3) All options were granted under the Company's 1995 Stock Option Plan. All
    options granted had an exercise price equal to the fair market value on the
    date of grant. All options were granted on dates that

EMPLOYMENT AGREEMENTS
 
    The Company has entered into employment agreements (the "Employment
Agreements") with Jonathan Edelson, M.D., its Chairman and Chief Executive
Officer, Steven Hochberg, its President, Alan B. Masarek, its Chief Operating
Officer and Chief Financial Officer, Robert Alger, its Vice President and Chief
Information Officer, and Andrew C. Garling, M.D., its Vice President and Chief
Medical Officer (each, an "Employee"). The Employment Agreements provide that
the annual base salary of each of the Employees is: Dr. Edelson, $220,000; Mr.
Hochberg, $220,000; Mr. Masarek, $200,000; Mr. Alger, $154,000; and Dr. Garling,
$200,000. The Employees are also entitled to receive discretionary bonuses.
 
    The Employment Agreements generally provide for a three-year term that is
automatically renewable for successive one-year terms unless either party gives
prior written notice of its intent not to renew. The Employment Agreements set
forth the compensation arrangements and the employee fringe benefits provided by
the Company to each Employee. In addition, the Employment Agreements set forth
the compensation payable to an Employee in the event of a termination of the
Employee's employment by the Company. Generally, upon the termination of an
Employee's employment by the Company for cause, the Employee is entitled to
receive earned but unpaid salary and reimbursement for business expenses
incurred during the performance of the Employee's duties. If an Employee's
employment with the Company is terminated without cause, due to the death or
incapacity of the Employee or within a specified period after a change of
control (as defined in the Employment Agreements), the Employee is entitled to
receive the amounts payable in the event of a termination for cause plus a cash
severance payment not to exceed the cash compensation received by the Employee
in the prior 12-month period and the vesting of certain shares of Common Stock
and options to purchase
 
                                       47
<PAGE>
Common Stock of the Company then held by such Employee. Each Employment
Agreement provides a non-compete provision that restricts an Employee from
competing against the Company for a period of one-year following such Employee's
termination of employment with the Company.
 
STOCK PLANS
 
    1995 Stock Option Plan. The Company has adopted the 1995 Stock Option Plan
(the "1995 Plan"). The 1995 Plan permits the grant of (i) options to purchase
shares of Common Stock intended to qualify as incentive stock options under
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code")
("Incentive Stock Options"), and (ii) options that do not so qualify
("Non-Qualified Options"). No award may be granted under the 1995 Plan after the
tenth anniversary of the Plan's adoption. The 1995 Plan is administered by the
Compensation Committee.
 
    1,500,000 shares of Common Stock have been reserved for issuance under the
1995 Plan, subject to adjustment for stock splits, stock dividends,
recapitalizations, reclassifications and similar events. If an option granted
under the 1995 Plan expires unexercised or is terminated or cancelled for any
reason, the shares of Common Stock previously reserved for issuance thereunder
will be available for future option grants under the 1995 Plan.
 
    Options may be granted to persons who are, at the time of grant, employees,
officers or directors of, or consultants or advisors to, the Company, provided
that Incentive Stock Options may only be granted to individuals who are
employees of the Company (within the meaning of Section 3401(c) of the Code).
 
    Options granted under the 1995 Plan must be exercised within no more than
ten years of the grant date, except that an Incentive Stock Option granted to a
person owning more than 10% of the total combined voting power of all classes of
stock of the Company (a "Ten Percent Stockholder") must be exercised within no
more than five years of the grant date. No options may be assigned or
transferred by the optionee other than by will or the laws of descent or
distribution or pursuant to a qualified domestic relations order (as defined in
the Code or Title I of the Employee Retirement Income Security Act, or the rules
thereunder). Each option may be exercised only by the optionee during his or her
lifetime.
 
    The exercise price for each option granted will be determined by the
Compensation Committee at the time of grant. For Incentive Stock Options granted
to a Ten Percent Stockholder, the exercise price shall not be less than 110% of
the fair market value per share of Common Stock.
 
    Options may be made exercisable in installments, and the exercisability of
Options may be accelerated by the Compensation Committee. Options granted under
the 1995 Plan typically vest over a three-year period.
 
    In the event of a consolidation or merger in which the Company is not the
surviving corporation, or sale of all or substantially all of the assets of the
Company in which outstanding shares of Common Stock are exchanged for
securities, cash or other property of any other corporation or business entity
or a liquidation of the Company (a "Corporate Transaction"), the Compensation
Committee, or the board of directors of any corporation assuming the obligations
of the Company, may, in its discretion, take any one or more of the following
actions, as to outstanding options: (i) provide that such options shall be
assumed, or equivalent options shall be substituted, by the acquiring or
succeeding corporation (or an affiliate thereof), provided that any such option
substituted for incentive stock options shall meet the requirements of Section
424(a) of the Code; (ii) upon written notice to the optionee, provide that all
unexercised options will terminate immediately prior to the consummation of such
transaction unless exercised by the optionee within a specified period following
the date of such notice; (iii) in the event of a Corporate Transaction under the
terms of which holders of the Common Stock of the Company will receive upon
consummation thereof a cash payment for each share surrendered in the Corporate
Transaction (the "Transaction Price"), make or provide for a cash payment to the
optionees equal to the difference between (A) the Transaction Price times the
number of shares of Common Stock subject to such outstanding options (to the
extent then exercisable at prices not in excess of the Transaction Price)
 
                                       48
<PAGE>
and (B) the aggregate exercise price of all such outstanding options in exchange
for the termination of such options, and (iv) provide that all or any
outstanding options shall become exercisable in full immediately prior to any
such event.
 
    As of the date of this Prospectus, an aggregate of 843,846 outstanding
options had been granted to approximately 80 directors, officers, employees and
consultants at a weighted average exercise price of $3.13 per share and an
aggregate of 156,154 shares were available for future option grants. Of such
outstanding options, 101,286 were granted to Dr. Edelson, 101,286 to Mr.
Hochberg, 86,037 to Mr. Masarek, 43,196 to Mr. Alger, 39,472 to Dr. Garling,
7,507 to Mr. Kurokawa and 7,507 to Mr. Lieber.
 
    Employee Stock Purchase Plan. The Company has adopted, effective upon the
date of this Prospectus, an employee stock purchase plan (the "Stock Purchase
Plan"). The purpose of the Stock Purchase Plan is to allow the employees of the
Company to acquire a proprietary interest in the Company through the purchase of
shares of Common Stock. Under the Stock Purchase Plan, eligible employees will
be granted options (exercisable by electing to participate in the Plan) to
purchase shares of Common Stock through regular payroll deductions. The Stock
Purchase Plan is intended to qualify as an "employee stock purchase plan" under
Section 423 of the Code. The total number of shares of Common Stock that are
authorized for issuance under the Stock Purchase Plan is 1,200,000. All full-
time employees of the Company who have completed at least one year of employment
will be eligible to participate in the Stock Purchase Plan, subject to certain
limited exceptions. Options will be granted every six months to eligible
employees and, if not exercised, will expire on the last day of the six-month
period in which granted. Employees electing to participate for any plan year
will authorize payroll deductions at a stated whole percentage ranging from 2%
to 10% of compensation, as determined by the participant. Employees may also
elect to make payments by check payable to the Company to purchase shares of
Common Stock. Options will be nontransferable other than by will or by operation
of the laws of descent and distribution. The purchase price for shares offered
under the Stock Purchase Plan each year will be equal to a percentage designated
by the Board of Directors (not less than 85%) of the lower of the fair market
value of the Common Stock at the date of grant or the semi-annual date of
exercise as evidenced by the high and low sales prices of the Common Stock on
such date as reported on the Nasdaq National Market. The Stock Purchase Plan
will expire on the tenth anniversary of the date of this Prospectus, unless
sooner terminated by the Board of Directors. The Board of Directors of the
Company may amend, suspend or terminate the Stock Purchase Plan at any time and
from time to time, subject to certain limitations. The Stock Purchase Plan will
be administered by the Compensation Committee.

space in Tarrytown, New York from Physicians' Online, Inc. ("Physicians'
Online"), a Delaware corporation of which Dr. Edelson, Mr. Hochberg and Dr.
Mayaud own approximately 16% of the currently outstanding capital stock.
Physicians' Online was founded in January 1992 by Mr. Hochberg and Dr. Mayaud.
The
 
                                       50
<PAGE>
yearly base rental on the Physicians' Online sublease equals $77,707, plus
escalations. During the period ended December 31, 1993, the years ended December
31, 1994 and 1995 and the three months ended March 31, 1996, Physicians' Online
incurred administrative expenses totalling $105,116, $135,825, $180,631 and
$25,500, respectively, on behalf of the Company for which the Company reimbursed
Physicians' Online. During 1993, Physicians' Online paid the Company a $175,000
fee for the development and implementation of a wireless application. The
Company does not expect to continue to receive administrative services from
Physicians' Online in the future. During 1994, Physicians' Online loaned the
Company $300,000, which loan bore interest at the prime rate. At December 31,

unaffiliated third parties. All future transactions, including loans, between
the Company and its officers, directors and principal stockholders and their
affiliates will be approved by a majority of the Board of Directors, including a
majority of the independent and disinterested outside directors of the Board of
Directors.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    Following the closing of the sale of the shares offered hereby, the
Company's authorized capital stock will consist of 15,000,000 shares of Common
Stock, par value $.01 per share, and 5,000,000 shares of Preferred Stock, par
value $.01 per share. The following summaries of certain provisions of the
Common Stock and Preferred Stock do not purport to be complete and are subject
to, and qualified by, the provisions of the Company's Restated Certificate of
Incorporation and By-laws, which are included as exhibits to the Registration
Statement of which this Prospectus is a part, and by applicable law.
 
COMMON STOCK
 
    As of July 12, 1996, there were 4,500,267 shares of Common Stock outstanding
that were held of record by approximately 80 stockholders, after giving effect
to the Stock Splits and the Preferred Stock Conversion. The holders of Common
Stock are entitled to one vote for each share on all matters voted upon by
stockholders, including the election of directors. Subject to the rights of any
then out Preferred Shares, the holders of the Common Stock are entitled to such
dividends as may be declared in the discretion of the Board of Directors out of
funds legally available therefor. Holders of the Common Stock are entitled to
share ratably in the net assets of the Company upon liquidation after payment or
provision for all liabilities and any preferential liquidation rights of any
Preferred Shares then outstanding. The holders of Common Stock have no
preemptive rights to purchase shares of stock of the Company. Shares of Common
Stock are not subject to any redemption provisions and are not convertible into
any other securities of the Company. All outstanding shares of Common Stock are,
and the shares of Common Stock to be issued pursuant to this offering will be,
upon payment of consideration therefor, fully paid and nonassessable.
 
PREFERRED STOCK
 
    Preferred Stock may be issued from time to time by the Board of Directors as
shares of one or more classes or series. Subject to the provisions of the
Company's Restated Certificate of Incorporation and limitations prescribed by
law, the Board of Directors is expressly authorized to adopt resolutions to
issue the shares, to fix the number of shares and to change the number of shares
constituting any series, and to provide for a change in the voting power,
designations, preferences and relative, participating, optional or other special
rights, qualifications, limitations or restrictions thereof, including dividend
rights (including whether dividends are cumulative), dividend rates conversion
rights and liquidation preferences of the shares constituting any class or
series of the Preferred Stock, in each case without any further action or vote
by the stockholders. Although the Company has no present plans to issue any
shares of Preferred Stock following the consummation of this offering, the
issuance of shares of Preferred Stock, or the issuance of rights to purchase
such shares, may have the effect of delaying, deferring or preventing a change
in control of the Company or an unsolicited acquisition proposal.
 
REGISTRATION RIGHTS
 
    The holders of 2,941,985 shares of the Company's Common Stock are entitled
to certain rights with respect to the registration of shares of Common Stock
under the Securities Act. Under the terms of the agreements between the Company
and the holders of such registrable securities, if the Company proposes to
register any of its securities under the Securities Act, either for its own
account or for the account of other security holders exercising registration
rights, such holders are entitled to notice of such registration and are
entitled to include shares of such Common Stock therein. These registration
rights have been waived in connection with this Offering. The stockholders
benefiting from these rights may also require the Company to file a registration
statement under the Securities Act at its expense
 
                                       53
<PAGE>
with respect to their shares of Common Stock, and the Company is required to use
its best efforts to effect such registration. These registration rights will
expire within three years from the consummation of this Offering and have been
waived by such holders in connection with this Offering. In addition, these
stockholders have the right to require the Company to file up to two additional
registration statements on Form S-3. This right becomes available upon the
eligibility of the Company to use such Form S-3 and will expire within three
years from the consummation of this Offering. All of these rights are subject to
certain conditions and limitations, including the right of the underwriters of
an offering to limit the number of shares included in such registration.
 
    In connection with the outstanding warrants, the holders of the Common Stock
issuable upon exercise of the warrants have certain rights to request the
Company to use its best efforts to effect the registration of the Common Stock
issuable upon the exercise of the warrants in connection with a registered
offering of Common Stock by the Company; provided that the Company will be
required to use its best efforts to include any such Common Stock issuable upon
the exercise of the warrants only after the registration of the Company's own
securities to the extent the underwriter for any such offering would not deem
any inclusion of such Common Stock issuable upon exercise of the warrants to
interfere with such offering. The warrant holders have waived these rights in
connection with this Offering. The rights to notice and inclusion in any
registration terminates with respect to each such share of Common Stock when
such shares issuable upon exercise of the warrants have been registered or sold.
 
CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BY-LAWS
 
    As described below, the Company's Restated Certificate of Incorporation and
By-laws contain certain provisions that are intended to enhance the likelihood
of continuity and stability in the composition of the Company's Board of
Directors and which may have the effect of delaying, deterring or preventing a
future takeover or change in control of the Company unless such takeover or
change in control is approved by the Company's Board of Directors. Such
provisions may also render the removal of the directors and management more
difficult.
 
    Pursuant to the Restated Certificate of Incorporation, the Board of
Directors of the Company is divided into three classes serving staggered
three-year terms. The By-laws establish an advance notice procedure with regard
to the nomination, other than by or at the direction of the Board of Directors,
of candidates for election as directors and with regard to certain matters to be
brought before an annual meeting of stockholders of the Company. In general,
notice must be received by the Company not less than 130 days prior to the
meeting and must contain certain specified information concerning the person to
be nominated or the matter to be brought before the meeting and concerning the
stockholder submitting the proposal. Special meetings of stockholders may be
called only by the Chairman of the Board, the President of the Company or the
Board of Directors. In addition, the Certificate of Incorporation provides that
stockholders may act only at an annual or special meeting and stockholders may
not act by written consent.
 
SECTION 203 OF THE DGCL
 
    Section 203 of the DGCL ("Section 203") prevents an "interested stockholder"
(defined in Section 203, generally, as a person owning 15% or more of a
corporation's outstanding voting stock) from engaging in a "business
combination" (as defined in Section 203) with a publicly-held Delaware
corporation for three years following the date such person became an interested
stockholder unless (i) before such person became an interested stockholder, the
board of directors of the corporation approved either the business combination
or the transaction that resulted in the interested stockholder's becoming an
interested stockholder, the interested stockholder owns at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding stock held by directors who
 
                                       54
<PAGE>
are also officers of the corporation and by employee stock plans that do not
provide employees with the right to determine confidentially whether shares held
subject to the plan will be tendered in a tender or exchange offer); or (iii)
following the transaction in which such person became an interested stockholder,
the business combination is approved by the board of directors of the
corporation and authorized at a meeting of stockholders by the affirmative vote
of the holders of two-thirds of the outstanding voting stock of the corporation
not owned by the interested stockholder.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the shares of Common Stock of the
Company is The Bank of New York.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market could adversely affect the prevailing market price from time to time.
Furthermore, because only a limited number of shares will be available for sale
shortly after this offering because of certain contractual and legal
restrictions on resale (as described below), sales of substantial amounts of
Common Stock in the public market after the restrictions lapse could adversely
affect the prevailing market price and the ability of the Company to raise
equity capital in the future. See "Risk Factors -- Shares Eligible for Future
Sale."
 
    Upon completion of this offering, the Company will have outstanding
6,500,267 shares of Common Stock (assuming no exercise of the Underwriters'
over-allotment option or outstanding options). Of these shares, the 2,000,000
shares sold in this offering will be freely transferable without restriction or
further registration under the Securities Act unless purchased by "affiliates"
of the Company as that term is defined in Rule 144 of the Securities Act (an
"Affiliate"), which shares will be subject to the resale limitations of Rule 144
adopted under the Securities Act. The remaining 4,500,267 shares outstanding
upon completion of this offering and held by existing shareholders will be
"restricted securities" as that term is defined under Rule 144 (the "Restricted
Shares"). Restricted Shares generally may be sold in the public market only if
registered or if they qualify for an exemption from registration under Rules
144, 144(k) or 701 promulgated under the Securities Act, which rules are
summarized below. As a result of the contractual restrictions described below
and the provisions of Rules 144, 144(k) and 701, additional shares will be
available for sale in the public market as follows: (i) no shares of Common
Stock (other than those shares sold hereby and not held by Affiliates) will be
available for immediate sale in the public market on the date of this
Prospectus, (ii) 19,272 shares of Common Stock subject to options exercisable
within 90 days of the date of this Prospectus will be freely tradeable by
non-Affiliates upon the effectiveness of a registration statement relating to
such stock options, (iii) 224,566 shares of Common Stock and 18,432 shares of
Common Stock subject to options exercisable within 90 days of the Effective Date
will be eligible for sale 90 days after the Effective Date, subject to the
volume, manner of sale and reporting requirements of Rule 144 and (iv)
approximately 4,266,800 shares of Common Stock and approximately 9,500 shares of
Common Stock subject to options exercisable within 180 days of the Effective
Date will be eligible for sale upon expiration of the lock-up agreements 180
days after the Effective Date, subject to the volume, manner of sale and
reporting requirements of Rule 144.
 
    The Company plans to file registration statements to register Common Shares
reserved for issuance under its stock option plans and employee stock purchase
plan. See "Management -- Stock Plans." Once registered, persons acquiring such
shares, whether or not they are Affiliates, will be permitted to resell their
shares in the public market without regard to the Rule 144 holding period.
 
                                       55
<PAGE>
    Upon completion of this offering, the holders of 2,941,985 shares of Common
Stock, or their transferees, will be entitled to certain rights with respect to
the registration of such shares under the Securities Act. See "Description of
Capital Stock -- Registration Rights." Registration of such shares under the
Securities Act would result in such shares (except for shares purchased by
Affiliates) becoming eligible for sale immediately upon the effectiveness of
such registration.
 
    The Company has agreed not to sell or otherwise dispose of any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock, or enter into any swap or similar agreement that transfers, in
whole or in part, the economic risk of ownership of the Common Stock, for a
period of 180 days after the Effective Date, without the prior written consent
of Cowen & Company, subject to certain limited exceptions. Additionally, all
directors and executive officers and certain other shareholders of the Company,
holding in the aggregate approximately 4,266,800 shares of Common Stock
outstanding prior to this offering, have agreed with the Underwriters not to
sell or otherwise dispose of any shares of Common Stock for a period of 180 days
after the Effective Date (the "Lockup Period") without the prior written consent
of Cowen & Company. See "Underwriting." The number of shares of Common Stock
available for sale in the public market is further limited by restrictions under
the Securities Act.
 
    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least two years, including
persons who may be deemed "affiliates" of the Company, would be entitled to sell
within any three-month period a number of shares that does not exceed the
greater of one percent of the number of shares of Common Stock then outstanding
or the average weekly trading volume of the Common Stock as reported through the
Nasdaq National Market during the four calendar weeks preceding the filing of a
Form 144 with respect to such sale. Sales under Rule 144 are also subject to
certain manner of sale provisions and notice requirements and to the
availability of current public information about the Company. In addition, a
person who is not deemed to have been an affiliate of the Company at any time
during the 90 days preceding a sale, and who has beneficially owned for at least
three years the Restricted Shares proposed to be sold, would be entitled to sell
such shares under Rule 144(k) without regard to the volume limitation, manner of
sale provisions, public information requirements or notice requirements. The
Commission has proposed certain amendments to Rule 144 and Rule 144(k) that
reduce the applicable requisite holding periods to one year and two years,
respectively.
 
    Subject to certain limitations on the aggregate offering price of a
transaction and certain other conditions, Rule 701 permits resales of shares
issued prior to the date the issuer becomes subject to the reporting
requirements of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), pursuant to certain compensatory benefit plans and contracts commencing
90 days after the issuer becomes subject to the reporting requirements of the
Exchange Act, in reliance upon Rule 144 but without compliance with certain
restrictions, including the holding period requirements, contained in Rule 144.
In addition, the Commission has indicated that Rule 701 will apply to typical
stock options granted by an issuer before it becomes subject to the reporting
requirements of the Exchange Act, along with the shares acquired upon exercise
of such options (including exercises after the date of this Prospectus).
Securities issued in reliance on Rule 701 are restricted securities and, subject
to the contractual restrictions described above, beginning 90 days after the
date of this Prospectus, may be sold by persons other than Affiliates subject
only to the manner of sale provisions of Rule 144 and by Affiliates under Rule
144 without compliance with its two-year minimum holding period requirements.

    The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent, including the absence of any
material adverse change in the Company's business and the receipt of certain
certificates, opinions and letters from the Company and its counsel and
independent auditors. The nature of the Underwriters' obligation is such that
they are committed to purchase all shares of Common Stock offered hereby if any
of such shares are purchased.
 
    The Underwriters propose to offer the shares of Common Stock directly to the
public at the initial public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession not in excess
of $      per share. The Underwriters may allow and such dealers may re-allow a
concession not in excess of $      per share to certain other dealers. The
Underwriters have informed the Company that they do not intend to confirm sales
to any accounts over which they exercise discretionary authority. After the
initial public offering of the shares, the offering price and other selling
terms may from time to time be varied by the Underwriters.
 
    The Company has granted to the Underwriters an option, exercisable no later
than 30 days after the date of this Prospectus, to purchase up to 300,000
additional shares of Common Stock at the initial public offering price, less the
underwriting discounts and commissions, set forth on the cover page of this
Prospectus, to cover over-allotments, if any. If the Underwriters exercise such
over-allotment option, the Underwriters have severally agreed, subject to
certain conditions, to purchase approximately the same percentage thereof that
the number of shares of Common Stock to be purchased by each of them shown in
the foregoing table bears to the total number of shares of Common Stock offered
hereby. The Underwriters may exercise such option only to cover over-allotments
made in connection with the sale of shares of Common Stock offered hereby.
 
    The Company's officers and directors and certain other shareholders of the
Company holding in the aggregate approximately 4,266,800 shares of Common Stock
and approximately 9,500 shares of Common Stock subject to options exercisable
within 180 days of the effective date have agreed that they
 
                                       57
<PAGE>
will not, without the prior written consent of Cowen & Company, offer, sell,
contract or grant any option to purchase or otherwise dispose of any shares of
Common Stock, options, rights or warrants to acquire shares of Common Stock, or
securities exchangeable for or convertible into shares of Common Stock owned by
them during the 180-day period commencing on the Effective Date. In addition,
the Company has agreed that it will not, without the prior written consent of
Cowen & Company, offer, sell, contract or grant any option to purchase or
otherwise dispose of any shares of Common Stock, options, rights or warrants to
acquire shares of Common Stock or securities exchangeable for or convertible
into shares of Common Stock during such 180-day period except in certain limited
circumstances.
 
    The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, and to contribute
to payments the Underwriters may be required to make in respect thereof.
 
    Prior to this offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock will be determined
by negotiation among the Company and the Representatives. Among the factors
considered in determining the initial public offering price will be prevailing
market and economic conditions, market valuations of other companies engaged in
activities similar to the Company, estimates of the business potential and
prospects of the Company, the present state of the Company's business
operations, the Company's management and other factors, if any, deemed relevant.
The estimated initial public offering price range set forth on the cover of this
Prospectus is subject to change as a result of market conditions and other
factors.
 
                                 LEGAL MATTERS
 
    The validity of the shares of Common Stock offered hereby will be passed

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Advanced Health Corporation:
 
    We have audited the accompanying consolidated balance sheets of Advanced
Health Corporation (formerly Med-E-Systems Corporation) (a Delaware corporation)
and subsidiaries as of December 31, 1994 and 1995, and the related consolidated
statements of operations, shareholders' equity (deficit) and cash flows for the
period from inception (August 27, 1993) to December 31, 1993 and for the years
ended December 31, 1994 and 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 audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Advanced Health Corporation
(formerly Med-E-Systems Corporation) and subsidiaries as of December 31, 1994
and 1995, and the results of their operations and their cash flows for the
period from inception to December 31, 1993 and for the years ended December 31,
1994 and 1995 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1994 AND 1995
 
1. ORGANIZATION AND BUSINESS
 
    Advanced Health Corporation and subsidiaries (collectively, the "Company" or
"AHC"), provides physician groups and networks with practice and network
management services and clinical information systems and services. The Company's
wholly-owned subsidiary was incorporated on August 27, 1993 as Med-E-Systems
Corporation (formerly Med-E-Mail Corporation), and was engaged at inception to
design and develop clinical information systems for physician users. Effective
August 1995, Med-E-Systems Corporation became a wholly-owned subsidiary of AHC,
an entity incorporated in March 1995, through a stock-for-stock transfer in
which preferred and common shareholders of Med-E-Systems Corporation exchanged
their interests for the same amounts and classes of preferred and common stock
in AHC as those then outstanding in Med-E-Systems Corporation. The Company was
subsequently merged with and into Majean, Inc. (Note 3), a Delaware corporation,
and the surviving corporation changed its name to Advanced Health Corporation.
Concurrent with this transaction, the Company raised approximately $5 million in
a private placement of its securities for the principal purposes of funding the
ongoing development of the Company's clinical information systems and services
and the Company's forward integration into physician practice and network
management services. Management of the Company believes that this financing, as
well as the bridge financing described in Note 14, will be adequate to fund the
Company's operations at least through January 1997.
 
    The Company operates in a highly-regulated environment in which its sources
of revenues are dependent on the Company's ability to successfully negotiate
with third parties for its various services. Currently, the Company depends on
revenue generated by a limited number of customers, including physician groups
and networks which are under long-term contracts.
 
    For a discussion of risks associated with the Company and its business, see
"Risk Factors" in the accompanying initial public offering (Note 14)
registration statement of which these consolidated financial statements and
notes to consolidated financial statements are a part.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF CONSOLIDATION
 
    The accompanying consolidated financial statements include the accounts of
AHC and its wholly-owned subsidiaries: Advanced Health Management Corporation
("AHM", formerly Advanced Clinical Networks Corporation), Med-E-Systems
Corporation ("MES") and Management Service Organization subsidiaries ("MSOs")
established to facilitate the provision of management services to physician
practice and network clients. These consolidated financial statements include
the results of operations of the Company from the inception of MES in August
1993, including other entities formed or acquired from their formation or
acquisition, through December 31, 1995. The structure of the Company's wholly or
majority-owned MSOs presently provides for the Company to receive activity-based
fee income from the MSOs for management services provided, and reimbursement
from the MSOs for certain expenses incurred, with the result being that there
are no profits in the MSO entity for which a minority interest is required to be
calculated. Accordingly, the consolidated financial statements do not reflect
any minority interest in the operations of the MSOs. In the event that profits
remain in MSO entities in the future, minority interests will be reflected in
the Company's consolidated financial statements. Intercompany accounts and
transactions have been eliminated in consolidation.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                           DECEMBER 31, 1994 AND 1995
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
REVENUE RECOGNITION
 
    Operating revenues are generated from three principal sources:
 
   
        (a) Physician Practice Revenues: A physician group practice is a single
    legal entity comprised of multiple physicians. Through its majority or
    wholly-owned consolidated MSOs, the Company enters into management services
    agreements with physician group practices, whereby such physician practices
    outsource their non-medical and administrative functions to the MSO.
    Activity-based fees are generated by the MSO through the provision of these
    outsourced services as well as certain additional management, marketing and
    information services. Fees for such services are either fixed or based on
    the level of services provided, as negotiated in the Company's various
    agreements for the provision of services, and are recognized monthly or as
    these services are rendered, respectively, based on the terms of the related
    agreements. The Company's contracts with its physician group practices also
    include pre-determined incentives which are earned and recognized as revenue
    in the event that the Company is successful in reducing a physician group
    practice's administrative expenses.
    
 
   
        (b) Physician Network Revenues: A physician network is an aggregation of
    individual physicians and physician groups formed for the purpose of
    entering into contracts with third-party payors. A physician network enters
    into a contract with a third-party payor pursuant to which the physicians
    comprising the network agree to provide medical services to network
    enrollees in return for a fixed per enrollee fee. Such contracts are known
    as "capitated contracts." The physician network then enters into a
    management services agreement with the Company's majority-owned,
    consolidated MSO, pursuant to which the aggregate capitated payments are
    assigned to the MSO. From these capitated payments, the MSO pays a fixed
    percentage of the capitated premium to fund all administrative and
    management services required under the contract. After payment of such
    administrative and management services expenses, the MSO pays the network
    physicians in return for the physicians' provision of medical services to
    medical enrollees. Such payments are based on a pre-determined fee schedule
    established based on actuarial predictions of required medical utilization
    by the networks' enrollees. In the event that total capitated premiums
    exceed the sum of the costs of (i) administrative and management services
    provided and (ii) the physicians' provision of medical services to the
    network enrollees, such savings are shared between the MSO and the network
    physicians in differing pre-determined amounts. In the event that total
    capitated premiums are less than the sum of the abovementioned costs, such
    costs are accrued and are borne proportionally by the MSO. The Company will
    recognize in its financial statements only those revenues earned in
    connection with the provision of management services related to these
    capitated arrangements.
    
 
   
        In the event that contracts between MSOs and physician practices and
    networks are terminated, the terms of the related contracts do not require
    the Company, through the MSOs, to return any previously-earned revenues.
    
 
        (c) Information Systems and Services Revenue: The Company's current
    business strategy for providing integrated physician practice and network
    management services includes selling its information systems and services as
    a means of ultimately providing a full range of services. The Company has,
    in order to generate funds and demonstrate the uses of its systems, licensed
    certain components of its software to third parties.

                           DECEMBER 31, 1994 AND 1995
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
        The Company recognizes revenue from the sale of its information systems
    and services (upon installation and acceptance), and from the licensing of
    its software to third parties (upon delivery). Certain of these third
    parties provide payment in advance for the development and installation of
    software, databases and systems. The Company accounts for these advance
    payments as deferred revenue when received, and recognizes revenue ratably
    over the period of time during which the software is delivered and services
    are performed. In December 1991, the American Institute of Certified Public
    Accountants issued Statement of Position ("SOP") 91-1, "Software Revenue
    Recognition". The Company's revenue recognition policy is in compliance with
    the provisions of this SOP.
 
CONCENTRATION OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of trade receivables from physician practice
revenues, physician network revenues and information systems and services
revenues.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment, consisting primarily of electronic data processing
equipment, are stated at cost and depreciated on a straight-line basis over the
useful lives of the assets (3 to 5 years). Equipment held under capital leases
is amortized utilizing the straight-line method over the lesser of the term of
the lease or the estimated useful life of the asset.
 
INTANGIBLE ASSETS
 
    The Company is in the process of allocating the excess of purchase price
over tangible net assets acquired in the acquisitions described in Note 3 to
specific categories of intangible assets. The total of such excess purchase
price is included in intangible assets and is presently being amortized over
periods of 15 to 20 years.
 
    These amortization periods are evaluated by management on a continuing
basis, and will be adjusted if the lives of the related intangible assets
(expected to be principally goodwill and management contracts) are impaired.
 
COMPUTER SOFTWARE COSTS
 
    The Company develops computer software which is marketed to third parties.
The Company capitalizes such costs in accordance with Statement of Financial
Accounting Standards No. 86, "Accounting for the Costs of Computer Software to
be Sold, Leased, or Otherwise Marketed". Amortization of such costs is provided
using the straight-line method over the estimated economic life of the products,
which is generally five years.
 
    The Company has $125,711, $100,569 and $87,998 of unamortized capitalized
computer software costs included in other assets in the accompanying
consolidated balance sheets as of December 31, 1994, December 31, 1995 and June
30, 1996 (unaudited), respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
    Computer software amortization expense aggregated $0, $0 and $25,142,
respectively, for the period ended December 31, 1993 and for the years ended
December 31, 1994 and 1995, and $12,571 in each of the six month periods ended
June 30, 1995 and 1996 (unaudited).
 
RESEARCH AND DEVELOPMENT
 
    Research and development costs are expensed as incurred by the Company.
 
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.
 
INCOME TAXES
 
    At inception, the Company adopted Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes", which requires recognition of
deferred tax liabilities and assets for the estimated future tax effects of
events that have been recognized in the financial statements or income tax
returns. Under this method, deferred tax liabilities and assets are determined
based on (1) differences between the financial accounting and income tax bases
of assets and liabilities, and (2) carry-forwards, using enacted tax rates in
effect for the years in which the differences and carry-forwards are expected to
reverse and be utilized, respectively (Note 11).
 
NET LOSS PER COMMON SHARE
 
    Net loss per common share was computed by dividing net loss by the weighted
average number of common shares and common share equivalents outstanding during
the respective years, which includes, for all periods, (i) the effect of the
conversion of common stock equivalent Class A, B, C and D Convertible Preferred
Stock to common stock, (ii) the retroactive effect of the reverse stock split,
both described in Note 14, which will occur concurrent with the consummation of
the Company's initial public offering and (iii) the impact of the issuance, in
the year prior to the Company's pending initial public offering (Note 14), of
504,477 warrants and options for all periods presented. Fully diluted net loss
per common share has not been presented since the inclusion of the impact of
stock options and warrants outstanding (Notes 3, 8, 10 and 14) would be
antidilutive.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
    During March 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of."
This statement establishes financial accounting and reporting standards for the
impairment of long-lived assets, certain identifiable intangibles, and goodwill
related to those assets to be held and used, and for long-lived assets and
certain identifiable

intangibles to be disposed of. This statement is effective for financial
statements for fiscal years beginning after December 15, 1995, although earlier
application is encouraged. It is the Company's policy to account for these
assets at the lower of amortized cost or fair value. As part of an ongoing
review of the valuation and amortization of such assets, management assesses the
carrying value of such assets on a continuing basis. If this review indicates
that the assets will not be recoverable as determined by a nondiscounted cash
flow analysis over the remaining amortization period, the carrying value of
these assets would be reduced to their estimated fair market values. The Company
does not expect the impact of the adoption of this pronouncement to be material.
 
    During October 1995, the Financial Accounting Standards Board issued SFAS
No. 123, "Accounting for Stock Based Compensation." This statement establishes
financial accounting and reporting standards for stock-based employee
compensation plans. SFAS No. 123 encourages entities to adopt a fair value based
method of accounting for stock compensation plans. However, SFAS No. 123 also
permits the Company to continue to measure compensation costs under pre-existing
accounting pronouncements. If the fair value based method of accounting is not
adopted, SFAS No. 123 requires pro forma disclosures of net income (loss) and
net income (loss) per common share in the notes to consolidated financial
statements. The accounting requirements of SFAS No. 123 are effective for
transactions entered into in fiscal years that begin after December 15, 1995,
though they may be adopted on issuance. The disclosure requirements of SFAS No.
123 are effective for financial statements for fiscal years beginning after
December 15, 1995, or for an earlier fiscal year for which SFAS No. 123 is
initially adopted for recognizing compensation cost. The Company has not yet
quantified the expected impact of the adoption of this pronouncement.
 
3. ACQUISITION OF BUSINESSES
 
ACQUISITIONS
 
    The transaction with Majean, Inc. described in Note 1 was accounted for as a
purchase through the issuance of 543,564 shares of the Company's stock to the
shareholders of Majean, Inc., who were not previously affiliated with the
Company, for an aggregate purchase price of $1,368,471. Additionally, options to
purchase 283,010 shares of common stock at $.0112 per share were issued as part
of this transaction. These options are only exercisable, as contingent
consideration, upon the achievement of certain capitalization levels related to
regulatory requirements. The entire purchase price of this acquisition has been
allocated to intangible assets in the accompanying consolidated balance sheet,
as will any contingent consideration which arises due to the option described
above, based on a twenty-year contract with a MSO, which was contributed to
Majean, Inc. by its shareholders upon its formation immediately prior to the
transaction. Accordingly, this intangible asset is being amortized over a period
of twenty years.
 
    Pursuant to an asset purchase agreement with Peltz Ventimiglia, Inc.
("Peltz") dated August 28, 1995, AHC acquired certain assets and assumed certain
liabilities of Peltz for 75,996 shares of common stock for an aggregate purchase
price of $191,327. Additionally, the former owners of Peltz received warrants to
purchase 113,995 shares of the Company's common stock at $4.38 per share, which

warrants are only exercisable, as contingent consideration, based on the
achievement of targeted operating performance.
 
    Pursuant to a purchase agreement with U.S. Health Connections, Inc. ("Health
Connections") dated September 1, 1995, the Company acquired, through its
subsidiary AHM, all of the outstanding stock of Health Connections for $150,000
in cash, a note for $150,000 due in two installments within one year of the
acquisition and 30,193 shares of common stock, for an aggregate purchase price
of $376,014. Furthermore, the Health Connections purchase agreement calls for
the issuance of an additional 56,611 shares of common stock, as contingent
consideration, based on the achievement of targeted operating performance by
this entity.
 
    The Company will record the effect of the contingent consideration related
to these acquisitions based upon the provisions of Emerging Issues Task Force
Issue 95-8, "Accounting for Contingent Consideration Paid to the Shareholders of
an Acquired Company in a Purchase Business Combination", which sets forth the
criteria for determining the allocation of contingent consideration as either
additional purchase price or compensation expense. These criteria provide for
the recognition of contingent consideration, as opposed to compensation expense,
upon the exercisability, if any, of such options and warrants where relevant
facts and circumstances, such as continued employment of the sellers, components
of the selling shareholder group, reasons for contingent payments and other
agreements and issues, indicate that such accounting is warranted. Management of
the Company believes that the terms of the acquisitions described above meet the
criteria for recognition of contingent consideration.
 
    These acquisitions described above were valued based on management's
estimate of the fair value of common stock at the date of acquisition, which was
determined by the Company's management by comparisons to (i) arms-length
transactions with unrelated third-parties for the same or similar securities and
(ii) an independent third-party appraisal. Costs in excess of net assets
acquired were recorded as intangible assets as follows:

    The Company shares office space and administrative services with Physicians'
Online, Inc. ("POL"), a healthcare information services company which is partly
owned by several of the Company's shareholders, including certain officers and
directors.
 
    During the year ended December 31, 1994, the Company earned $175,000 of
revenue from POL for information systems and services. During the period ended
December 31, 1993 and the years ended December 31, 1994 and 1995, POL also
incurred expenses totaling $105,116, $135,825 and $180,631, respectively, and
$117,362 and $50,500, respectively, for the six months ended June 30, 1995 and
1996 (unaudited), on behalf of the Company for which the Company has reimbursed
POL. The amount due POL, as well as a loan from POL in the amount of $300,000,
which has been repaid, is reflected as due to affiliate in the accompanying
consolidated balance sheet at December 31, 1994. In addition, during 1995, POL
borrowed $500,000 from the Company. POL repaid this amount in full prior to

in the accompanying consolidated financial statements.
 
    Management of the Company believes that these related party transactions

consolidated financial statements has been retroactively restated to give effect

Convertible Preferred Stock to common stock, both of which transactions will be
effected concurrently with the consummation of the pending initial public

consolidated statements of operations for the purpose of computing net loss per

    Subject to certain provisions, prior to the conversion to common stock,
registration rights, as defined in the agreement, were to be exercisable after
the earlier of (1) August 23, 1999, or (2) the effective date of the first
registration statement for a public offering of securities of the Company.
Holders of Series B, C and D Convertible Preferred Stock have voting rights.
Furthermore, holders of Series D Convertible Preferred Stock have the right to
purchase 446,858 shares of common stock at $8.39 per share.

STOCK WARRANTS
 
    In October 1995, the Company issued warrants to a financial advisor to
purchase 17,874 shares of common stock at $3.52 per share. In the opinion of
management, the exercise price of $3.52 per share represents the fair value of
such shares at the date the warrants were issued. Accordingly, management has
determined that the intrinsic value of these warrants is not material to the
Company's consolidated financial statements.
 
11. INCOME TAXES
 
    There is no provision for income taxes in the accompanying consolidated
financial statements because the Company has incurred net operating losses from
inception. As of December 31, 1995, the Company had net operating loss carry
forwards ("NOLs") available to offset future book and taxable income of
approximately $8.7 million and $6.2 million, respectively, which expire through
2010. The difference between the book and tax NOLs relates principally to the
differences between book and tax accounting related to start-up costs,
depreciation of fixed assets, amortization of intangible assets and recognition
of deferred revenue. The future book income tax benefits of $1.3 million and
$3.5 million as of December 31, 1994 and December 31, 1995, respectively, have
been fully reserved due to the fact that it is more likely than not that these
tax benefits will not be recognized in the future.
 
12. CAPITAL LEASE OBLIGATIONS
 
    The Company is the lessee of certain equipment under capital leases expiring
through 1998. The assets and liabilities are recorded at the lower of the
present value of minimum lease payments or the fair market value of the asset.
The interest rates on the capital leases vary from 2.63% to 17.00%.

14. SUBSEQUENT EVENTS
 
ACQUISITION
 
    On April 1, 1996, the Company acquired certain assets and assumed certain
liabilities of a network development company in exchange for 8,937 shares of the
Company's common stock and $45,000, to be paid in two installments of $22,500 on
the closing date and the first anniversary thereof, for an aggregate purchase
price of approximately $90,000, all of which is included in intangible assets
(Note 6) in the accompanying unaudited balance sheet as of June 30, 1996. The
pro forma effects of this transaction have not been presented, as the results
are immaterial to the Company's consolidated financial statements taken as a
whole.
 
FORMATION OF MSOS
 
    In July 1996, the Company obtained a 51% interest in Cardiology First
Management Company ("CFMC"), a newly formed MSO. The Company acquired this
interest as part of the formation of CFMC and concurrent with the signing of a
long-term management services agreement between CFMC and Cardiology First of New
Jersey, P.A., which is a network of cardiologists based in the State of New
Jersey.

14. SUBSEQUENT EVENTS--(CONTINUED)
    In July 1996, the Company obtained a 51% interest in Diamond Physician
Management, Inc. ("Diamond"), a newly formed MSO. The Company acquired this
interest as part of the formation of Diamond and concurrent with the signing of
a long-term management services agreement between Diamond and Long Island
Interventional Cardiology, which is a private cardiovascular physician practice
based in Long Island, New York.
 
    In forming these MSOs, the Company conveyed 49% interests to the physician
practice or network in exchange for the execution of the long-term management
services agreements described above. The Company will record the fair value of
this arrangement, which is, in the opinion of management, more readily
determinable than the 49% MSO interest conveyed. These intangible assets, which
the Company does not expect to be material, will be amortized over the life of
the related contracts.
 
    The stockholders agreements for these MSOs, among other things, (i) restrict
the transfer of MSO equity, (ii) provide the terms upon which the MSO can, at
the Company's option, be merged with and into a wholly-owned subsidiary of the
Company in a transaction in which the physician practice or network will receive
stock of the Company in exchange for shares in the MSO, and (iii) grant to the
physician practice or network the right to put its equity share in the MSO to
the Company within one year of the Company's satisfaction of certain specified
targets if the Company has not called its right to acquire those interests
within that period. The agreements provide that these call transactions will be
paid in the Company's common stock, and put transactions will be paid in cash,
and that either transaction, if effected, would be based on an agreed-upon
amount at the time of the transaction. The Company will, in the event that these
transactions take place, account for such transactions as purchases at the
agreed-upon fair market value of the MSO interest being purchased.
 
INITIAL PUBLIC OFFERING
 
    The Company is pursuing an initial public offering of its securities. The
proposed offering presently contemplates the sale of 2,000,000 shares of common
stock at $12 per share. The Company plans to use a portion of the proceeds of
the proposed offering to repay the Bridge Financing described below, of which
$4,000,000 was outstanding at June 30, 1996. The supplementary net loss per
share for the six months ended June 30, 1996 (unaudited), which follows, gives
supplemental effect to the issuance of 333,333 shares of common stock for the
entire period during which the related Bridge Financing was outstanding, which
is the number of shares to be issued in the proposed initial public offering,
the proceeds of which would be used to repay the $4,000,000 outstanding at June
30, 1996, as well as to the effect of the reduction of related interest expense
in that period. These shares are presumed outstanding for supplementary purposes
only, and were neither issued nor outstanding for any purpose during the six
months ended June 30, 1996.

conversion of the Series A, B, C and D Convertible Preferred Stock as if it had
occurred as of that date.
 
REVERSE STOCK SPLIT AND RECAPITALIZATION
 
    In connection with the pending initial public offering described above, the
Company will effect a recapitalization whereby the presently outstanding common
stock (including converted Series A, B, C and D Convertible Preferred Stock)
will be converted to shares of common stock on a .59581 to 1 share basis. After
this reverse split is effected, the Company will have 5,000,000 shares of
preferred stock authorized and 15,000,000 shares of common stock authorized. All
information contained in the accompanying financial statements and footnotes has
been retroactively restated to give effect to this transaction.
 
BRIDGE FINANCING
 
    On February 28, 1996, the Company entered into an agreement to issue three
8% promissory notes to an investor for an aggregate amount of $3,000,000. The
Company issued one promissory note and received $1,500,000 upon the closing,
issued a second promissory note and received $750,000 at the second closing
date, April 26, 1996, and issued a third promissory note and recieved the
remaining $750,000 on the third closing date, June 28, 1996. Each note is due on
the earlier of the initial public offering of the Company's securities or one
year from the respective closing dates. Interest is due quarterly on each of the
notes.
 
    In addition, the investor received warrants to purchase 16,757 shares of
common stock of the Company at $16.78 per share which expire on June 28, 2001.
The exercise price of $16.78 per share is, in the opinion of management, greater
than the fair market value of such shares at the date the warrants were issued.
The investor also received 8,937 contingent warrants to purchase the Company's
stock at $8.39 per share. These contingent warrants may be exercised during the
period of January 1, 1997 through June 28, 2001 if payment has not been made on
the notes by the agreed upon payment dates described above or if an initial
public offering is not consummated prior to January 1, 1997; however, if
payments on the notes are made by the specified dates, these contingent warrants
will be canceled.
 
    The Company has entered into an agreement with the owners of the Company's
Series D Convertible Preferred Stock and related warrants (Note 8) for
additional bridge financing in the amount of approximately $2,000,000. This
financing is unsecured, bears interest at 9% and expires on the earlier of the
consummation of an initial public offering or July 31, 1997. On June 19, 1996,
the Company issued three promissory notes in the aggregate principal amount of
$1 million and on August 13, 1996, the Company issued three additional
promissory notes in the aggregate principal amount of $1 million under this
agreement.
 
15. UNAUDITED INTERIM CONSOLIDATED FINANCIAL INFORMATION
 
    The unaudited consolidated financial information for the six months ended
June 30, 1995 and 1996 has been prepared in accordance with generally accepted
accounting principles for interim financial information. In the opinion of the
Company, these unaudited consolidated financial statements reflect all
adjustments necessary, consisting of normal recurring adjustments, for a fair
presentation of such data on a basis consistent with that of the audited data
presented herein. The consolidated results of operations for interim periods are
not necessarily indicative of the results to be expected for a full year.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Advanced Health Corporation:
 
    We have audited the accompanying balance sheets of Peltz Ventimiglia, Inc.
(a New York corporation) as of December 31, 1994 and August 31, 1995, and the
related statements of operations, shareholders' equity and cash flows for the
years ended December 31, 1993 and 1994 and for the eight months ended August 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 audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Peltz Ventimiglia, Inc. as
of December 31, 1994 and August 31, 1995, and the results of its operations and
its cash flows for the years ended December 31, 1993 and 1994 and for the eight
months ended August 31, 1995 in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                     DECEMBER 31, 1994 AND AUGUST 31, 1995


 
1. ORGANIZATION AND BUSINESS
 
    Peltz Ventimiglia, Inc. (the "Company") provides physician practice
management consulting services for physicians in the Eastern United States.
 
    On August 28, 1995, the Company entered into a purchase agreement with
Advanced Health Management Corporation ("AHM", formerly Advanced Clinical
Networks Corporation), a wholly-owned subsidiary of Advanced Health Corporation
("AHC"), whereby the Company sold its net assets to AHM for 75,996 shares of AHC
common stock for an aggregate sale price of $191,327.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
    Fees for physician practice management consulting services are recognized as
services are rendered.
 
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.
 
INCOME TAXES
 
    The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes", which requires
recognition of deferred tax liabilities and assets for the estimated future tax
effects of events that have been recognized in the financial statements or
income tax returns. Under this method, deferred tax liabilities and assets are
determined based on (1) differences between the financial accounting and income
tax bases of assets and liabilities, and (2) carry-forwards, using enacted tax
rates in effect for the years in which the differences and carry-forwards are
expected to reverse and be utilized, respectively.
 
    The Company operates under Subchapter S of the Internal Revenue Code and,
consequently, is not subject to Federal and certain state income taxes. The
stockholders include their pro rata share of the Company's income in their
personal income tax returns. It is the Company's policy to reimburse its
stockholders for any tax liability resulting from their inclusion of the
Company's income in their respective tax returns.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Advanced Health Corporation:
 
    We have audited the accompanying balance sheets of U.S. Health Connections,
Inc. (a Georgia corporation) as of December 31, 1994 and August 31, 1995, and
the related statements of operations, shareholders' equity and cash flows for
the year ended December 31, 1994 and for the eight months ended August 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 audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of U.S. Health Connections,
Inc. as of December 31, 1994 and August 31, 1995, and the results of its
operations and its cash flows for the year ended December 31, 1994 and for the
eight months ended August 31, 1995 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                     DECEMBER 31, 1994 AND AUGUST 31, 1995
 
1. ORGANIZATION AND BUSINESS
 
    U.S. Health Connections, Inc. (the "Company") commenced operations on
January 1, 1994. The Company provides physician network management services for
physician groups in the Southeastern United States.
 
    On September 1, 1995, the Company entered into a purchase agreement with
Advanced Health Management Corporation ("AHM", formerly Advanced Clinical
Networks Corporation), a wholly-owned subsidiary of Advanced Health Corporation
("AHC"), whereby the Company's shareholders sold all of their outstanding stock
to AHM for $150,000 in cash, a $150,000 note receivable and 30,193 shares of AHC
common stock, for an aggregate sale price of $376,014.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
    The Company enters into management services agreements with its network
clients whereby the Company recognizes administrative fees for managing
capitated contracts between health maintenance organizations ("HMOs") and
physician networks for the delivery of health care.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment, consisting primarily of electronic data processing
equipment, are stated at cost and depreciated on a straight-line basis over the
useful lives of the assets (5 years).
 
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.
 
INCOME TAXES
 
    The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes", which requires
recognition of deferred tax liabilities and assets for the estimated future tax
effects of events that have been recognized in the financial statements or
income tax returns. Under this method, deferred tax liabilities and assets are
determined based on (1) differences between the financial accounting and income
tax bases of assets and liabilities, and (2) carry-forwards, using enacted tax
rates in effect for the years in which the differences and carry-forwards are
expected to reverse and be utilized, respectively. The provision for income
taxes for each period includes both federal and state income taxes.

    Depreciation aggregated $5,200 for each of the year ended December 31, 1994
and the eight months ended August 31, 1995, respectively.
 
4. LONG-TERM DEBT
 
    The Company had a loan payable with a bank related to the acquisition of a
vehicle. This loan was payable, with interest at 7.5%, in equal installments
through December 1997 and was repaid in full subsequent to the sale of the
Company to AHC. Accordingly, all long-term debt is reflected as a current
liability in the accompanying balance sheet as of August 31, 1995.
 
5. RELATED PARTY TRANSACTION
 
    In 1995, the Company borrowed $6,000 from a related party of the majority
shareholder. The loan is due on demand and interest is payable, and is accrued
by the Company at August 31, 1995, at the payment date at a rate equal to the
Company's average borrowing rate.

ITEM 17. UNDERTAKINGS.
 
    The Registrant hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the DGCL, the Certificate of Incorporation and By-laws,
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 such Securities Act, and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in such
Securities Act and will be governed by the final adjudication of such issue.

    The Registrant hereby undertakes that:
 
        1. For purposes of determining any liability under the Securities 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 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
        2. For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.

            (a)  A registration statement on Form S-1 (File No. 333-
       06283), as amended in the form in which it became or becomes effective
       and also in such form as it may be when any post-effective amendment

       preeffective prospectuses included as part of the 




















<PAGE>

                                         2

       registration statement as originally filed or as part of any amendment
       or supplement thereto, or filed pursuant to Rule 424 under the
       Securities Act of 1933, as amended (the "Securities Act"), and the rules
       and regulations (the "Rules and Regulations") of the Securities and
       Exchange Commission (the "Commission") thereunder, copies of which have
       heretofore been delivered to you, has been carefully prepared by the
       Company in conformity with the requirements of the Securities Act and
       has been filed with the Commission under the Securities Act; and one or
       more amendments to such registration statement, including in each case
       an amended preeffective prospectus, copies of which amendments have
       heretofore been delivered to you, have been so prepared and filed (as so
       amended, the "Registration Statement").  If it is contemplated, at the
       time this Agreement is executed, that a post-effective amendment to the
       Registration Statement will be filed and must be declared effective
       before the offering of the Stock may commence, the term "Registration
       Statement" as used in this Agreement means the Registration Statement as
       amended by said post-effective amendment.  The term "Registration
       Statement" as used in this Agreement shall also include any registration
       statement relating to the Stock that is filed and declared effective
       pursuant to Rule 462(b) under the Securities Act.  The term "Prospectus"
       as used in this Agreement means the prospectus in the form included in
       the Registration Statement, or, (A) if the prospectus included in the
       Registration Statement omits information in reliance on Rule 430A under
       the Securities Act and such information is included in a prospectus
       filed with the Commission pursuant to Rule 424(b) under the Securities
       Act, the term "Prospectus" as used in this Agreement means the
       prospectus in the form included in the Registration Statement as
       supplemented by the addition of the Rule 430A information contained in
       the prospectus filed with the Commission pursuant to Rule 424(b) and (B)
       if prospectuses that meet the requirements of Section 10(a) of the
       Securities Act are delivered pursuant to Rule 434 under the Securities
       Act, then (i) the term "Prospectus" as used in this Agreement means the
       "prospectus subject to completion" (as such term is defined in Rule
       434(g) under the Securities Act) as supplemented by (a) the addition of
       Rule 430A information or other information contained in the form of
       prospectus delivered pursuant to Rule 434(b)(2) under the Securities Act
       or (b) the information contained in the term sheets described in Rule
       434(b)(3) under the Securities Act, and (ii) the date of such
       prospectuses shall be deemed to be the date of the term sheets.  The
       term "Preeffective Prospectus" as used in this Agreement means the
       prospectus subject to completion in the form included in the
       Registration Statement at the time of the initial filing of the
       Registration Statement with the Commission, and as such prospectus shall
       have been amended from time to time prior to the date of the Prospectus. 


            (b)       The Commission has not issued or threatened to issue any
       order preventing or suspending the use of any Preeffective Prospectus,
       and, at its date of issue, each Preeffective Prospectus conformed in all
       material respects with the requirements of the Securities Act and did
       not include any untrue statement of a













<PAGE>

                                         3

       material fact or omit to state a material fact required to be stated
       therein or necessary to make the statements therein, in the light of the
       circumstances under which they were made, not misleading; and, when the
       Registration Statement becomes effective and at all times subsequent
       thereto up to and including the Closing Date, the Registration Statement
       and the Prospectus and any amendments or supplements thereto contained
       and will contain all material statements and information required to be
       included therein by the Securities Act and conformed and will conform in
       all material respects to the requirements of the Securities Act and
       neither the Registration Statement nor the Prospectus, nor any amendment
       or supplement thereto, included or will include 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 the light of the
       circumstances under which they were made, not misleading; provided,
       however, that the foregoing representations, warranties and agreements
       shall not apply to information contained in or omitted from any
       Preeffective Prospectus or the Registration Statement or the Prospectus
       or any such amendment or supplement thereto in reliance upon, and in
       conformity with, written information regarding any Underwriter furnished
       to the Company by or on behalf of any Underwriter, directly or through
       you, specifically for use in the preparation thereof; there is no lease,
       contract, agreement or document required to be described in the
       Registration Statement or Prospectus or to be filed as an exhibit to the
       Registration Statement which is not described or filed therein as
       required; and all descriptions of any such leases, contracts, agreements
       or documents contained in the Registration Statement are accurate and
       complete descriptions of such documents in all material respects.

            (c)       Subsequent to the respective dates as of which
       information is given in the Registration Statement and Prospectus, and
       except as set forth or contemplated in the Prospectus, neither the
       Company nor any of its subsidiaries has incurred any material
       liabilities or obligations, direct or contingent, nor entered into any
       transactions not in the ordinary course of business, and there has not
       been any material adverse change in the condition (financial or
       otherwise), properties, business, management, prospects, net worth or
       results of operations of the Company and its subsidiaries considered as
       a whole, or any change in the capital stock, short-term or long-term
       debt of the Company and its subsidiaries considered as a whole.

            (d)       The financial statements, together with the related notes
       and schedules, set forth in the Prospectus and elsewhere in the
       Registration Statement fairly present, on the basis stated in the
       Registration Statement, the financial position and the results of
       operations and changes in financial position of the entities purported
       to be shown thereby at the respective dates or for the respective
       periods therein specified and have been prepared in accordance with
       generally accepted accounting principles applied on a consistent basis
       except as may be set forth in the Prospectus.  The pro forma financial
       statements set forth in the Registration Statement fairly presents, on
       the basis 













<PAGE>

                                         4

       stated in the Registration Statement, the information set forth therein,
       has been prepared in accordance with the Rules and Regulations and the
       guidelines of the Commission with respect to pro forma financial
       statements, has been properly compiled on the pro forma bases set forth
       therein and the assumptions used in the preparation thereof are
       reasonable and the adjustments used therein are appropriate to give
       effect to the transactions or circumstances referred to therein.  The
       selected financial data set forth in the Prospectus under the caption
       "Selected Consolidated Financial Data" fairly present, on the basis
       stated in the Registration Statement, the information set forth therein.

            (e)       Arthur Andersen, LLP, who have expressed their opinions
       on the audited financial statements and related schedules included in
       the Registration Statement and the Prospectus, are independent public
       accountants as required by the Securities Act and the Rules and
       Regulations.

            (f)       The Company has and each of its subsidiaries have been
       duly organized and are validly existing and in good standing as

       possession of and operating in compliance with all grants,
       authorizations, licenses, permits, consents, certificates and orders

       are valid and in full force and effect; and the Company is and each of
       such subsidiaries are duly qualified to do business and in good standing
       as foreign corporations in all other jurisdictions where their ownership
       or leasing of properties or the conduct of their businesses requires
       such qualification, except where the failure to be so qualified would
       not have a material adverse effect on the condition (financial or
       otherwise), properties, business, management, prospects, net worth or
       results of operations of the Company and its subsidiaries considered as
       a whole.  The Company has and each of its subsidiaries have all

       subsidiaries or affiliates is a party or of which any property of the
       Company or any subsidiary or affiliate is subject, which, if determined
       adversely to the Company or any such subsidiary or affiliate, might
       individually or in the aggregate (i) prevent or adversely affect the

       effectiveness of the Registration Statement, (iii) prevent or suspend
       the use of the Prospectus in any jurisdiction or (iv) result in a

       subject to the provisions of any material injunction, judgment, decree
       or order of any court, regulatory body or other governmental agency or
       body.  The description of the Company's litigation under the heading

       with the Rules and Regulations.

            (j)       The execution, delivery and performance of this Agreement
       and the consummation of the transactions herein contemplated will not
       result in a breach or violation of any of the terms or provisions of or
       constitute a default under any indenture, mortgage, deed of trust, note

       (including to issue, sell and deliver the Stock), and this Agreement has
       been duly and validly authorized, executed and delivered by the Company
       and is a valid and binding obligation of the Company, enforceable
       against the Company in accordance with its terms, except to the extent
       that rights to indemnity and contribution hereunder may be limited by
       federal or state securities laws or the public policy underlying such
       laws.

            (n)       The Company and its subsidiaries are in all material

       than as set forth in the Registration Statement and the Prospectus, no
       prospective change in any of such federal or state laws, rules or

       material adverse effect on the operations of the Company and its
       subsidiaries.

            (o)  The Company's conduct of its business complies in all material
       respects with the statutes relating to the corporate practice of

       Georgia.

            (p)  To the extent that the Company enters into risk-sharing or
       capitation arrangements in the manner described in the Prospectus, the
       Company is or will be exempt from regulation under any and all local,

       federal, state, local and foreign income, payroll, franchise and other
       tax returns and have paid all taxes shown as due thereon or with respect

       respective properties or assets that would adversely affect the
       financial position, business or operations of the Company and its
       subsidiaries.

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

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

       transaction or funding deficiency or any complete or partial withdrawal
       liability with respect to any pension, profit sharing or other plan
       which is subject to the Employee Retirement Income Security Act of 1974,

       case free and clear of all liens, encumbrances and defects except such

       adverse effect on the Company and its subsidiaries considered as a
       whole; and any real property and buildings held under lease by the
       Company and its subsidiaries are held by them under valid, subsisting

       leases) with such exceptions as would not have a material adverse effect
       on the Company and its subsidiaries considered as a whole, in each case
       except as described in the Prospectus.

            (z)  The Company and its subsidiaries are insured by insurers of

       engaged; and neither the Company nor any subsidiary of the Company has
       any reason to believe that it will not be able to renew its existing
       insurance coverage as and when such coverage expires, to obtain similar
       coverage from similar insurers as may be necessary to continue their
       business or to obtain any reinsurance in connection with risk-sharing or
       capitation arrangements which the Company may enter into as described in

       that (i) transactions are executed in accordance with management's
       general or specific authorization; (ii) transactions are recorded as
       necessary to permit preparation of financial statements in conformity

       management's general or specific authorization; and (iv) the recorded

       character required to be disclosed in the Prospectus.

            (ee) Neither the Company nor any of its subsidiaries is an
       "investment company" or an entity "controlled" by an "investment
       company" as such terms are defined in the Investment Company Act of
       1940, as amended (the "1940 Act"), and the rules and regulations
       thereunder, and the Company and its subsidiaries intend in the future to
       conduct their affairs in such a manner as to ensure that they will not
       become an "investment company" or a company "controlled" by an
       "investment company" within the meaning of the 1940 Act and such rules
       and regulations.

            (ff) There has been no storage, disposal, generation, manufacture,

       the Company or any of its subsidiaries in violation of any applicable 
       law, ordinance, rule, regulation, order, judgment, decree or permit or 
       which would require remedial action under any applicable law, ordinance, 
       rule, regulation, order, judgment, decree or permit, except for any 
       violation or remedial action which would not have, or could not be

       respect to which the Company or any of its subsidiaries had knowledge, 
       except for any such spill, discharge, leak, emission, injection, escapes,
       dumpings and releases which would not have or would not be reasonably 
       likely to have, singularly or in the aggregate with all such spills,

       releases, such a material adverse effect; and the terms "hazardous

            The Company will deliver the Firm Stock to the Representatives for
  the respective accounts of the several Underwriters in the form of definitive
  certificates, issued in such names and in such denominations as the
  Representatives may direct by notice in writing to the Company given at or
  prior to 12:00 Noon, New York Time, on the second full business day preceding
  the Firm Closing Date (as defined below) or, if no such direction is
  received, in the names of the respective Underwriters or in such other names
  as Cowen may designate (solely for the purpose of administrative convenience)
  and in such denominations as Cowen may determine, against payment of the
  aggregate Purchase Price therefor by certified or official bank check or
  checks in same day funds, payable to the order of the Company, all at the
  offices of Shearman & Sterling, 599 Lexington Avenue, New York, New York
                                                       -

  location of delivery of, and the form of payment for, the Firm Stock may be
  varied by agreement between the Company and Cowen.  The Firm Closing Date may
  be postponed pursuant to the provisions of Section 12.

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

            It is understood that either Representative, individually and not
  as Representative of the several Underwriters, may (but shall not be
  obligated to) make payment to the Company on behalf of any Underwriter or
  Underwriters, for the Stock to be purchased by such Underwriter or
  Underwriters.  Any such payment by either Representative shall not 















<PAGE>

                                        12

  relieve such Underwriter or Underwriters from any of its or their other
  obligations hereunder.

            The several Underwriters agree to make an initial public offering
  of the Firm Stock at the initial public offering price as soon after the
  effectiveness of the Registration Statement as in their judgment is
  advisable.  The Representatives shall promptly advise the Company of the
  making of the initial public offering.

            For the purpose of covering any over-allotments in connection with
  the distribution and sale of the Firm Stock as contemplated by the
  Prospectus, the Company hereby grants to the Underwriters an option to
  purchase, severally and not jointly, up to the aggregate number of shares of
  Optional Stock set forth opposite each Underwriter's name on Schedule A
  hereto, for an aggregate of up to 300,000 shares.  The price per share to be
  paid for the Optional Stock shall be the Purchase Price.  The option granted
  hereby may be exercised as to all or any part of the Optional Stock at any
  time, and from time to time, not more than thirty (30) days subsequent to the
  effective date of this Agreement.  No Optional Stock shall be sold and
  delivered unless the Firm Stock previously has been, or simultaneously is,
  sold and delivered.  The right to purchase the Optional Stock or any portion
  thereof may be surrendered and terminated at any time upon notice by the
  Underwriters to the Company.

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

            The Company will deliver the Optional Stock to the Underwriters (in
  the form of definitive certificates, issued in such names and in such
  denominations as the Representatives may direct by notice in writing to the
  Company given at or prior to 12:00 Noon, New York Time, on the second full
  business day preceding the Option Closing Date

  or, if no such direction is received, in the names of the respective
  Underwriters or in such other names as Cowen may designate (solely for the
  purpose of administrative convenience) and in such denominations as Cowen may
  determine), against payment of the aggregate Purchase Price therefor by
  certified or official bank check or checks in Clearing House funds (next day
  funds), payable to the order of the Company all at the offices of Shearman &
  Sterling, 599 Lexington Avenue, New York, New York 10022.  The Company shall
  make the certificates for the Optional Stock available to the Underwriters
  for examination not later than 10:00 A.M., New York Time, on the business day
  preceding the Option Closing Date at the offices of Cowen & Company,
  Financial Square, New York, New York 10005. The Option Closing Date and the
  location of delivery of, and the form of payment for, the Option Stock may be
  varied by agreement between the Company and Cowen.  The Option Closing Date
  may be postponed pursuant to the provisions of Section 12.

            4.   Covenants and Agreements of the Company.  The Company
                 ---------------------------------------
  covenants and agrees with the several Underwriters that:

            (a)  The Company will (i)  if the Company and the Representatives
       have determined not to proceed pursuant to Rule 430A, use its best
       efforts to cause the Registration Statement to become effective, (ii) if
       the Company and the Representatives have determined to proceed pursuant
       to Rule 430A, use its best efforts to comply with the provisions of and
       make all requisite filings with the Commission pursuant to Rule 430A and
       Rule 424 of the Rules and Regulations and (iii) if the Company and the
       Representatives have determined to deliver Prospectuses pursuant to Rule
       434 of the Rules and Regulations, to use its best efforts to comply with
       all the applicable provisions thereof.  The Company will advise the
       Representatives promptly as to the time at which the Registration
       Statement becomes effective, will advise the Representatives promptly of
       the issuance by the Commission of any stop order suspending the
       effectiveness of the Registration Statement or of the institution of any
       proceedings for that purpose, and will use its best efforts to prevent
       the issuance of any such stop order and to obtain as soon as possible
       the lifting thereof, if issued.  The Company will advise the
       Representatives promptly of the receipt of any comments of the
       Commission or any request by the Commission for any amendment of or
       supplement to the Registration Statement or the Prospectus or for
       additional information and will not at any time file any amendment to
       the Registration Statement or supplement to the Prospectus which shall
       not previously have been submitted to the Representatives a reasonable
       time prior to the proposed filing thereof or to which the
       Representatives shall reasonably object in writing or which is not in
       compliance with the Securities Act and the Rules and Regulations.

            (b)  The Company will prepare and file with the Commission,
       promptly upon the request of the Representatives, any amendments or
       supplements to the Registration Statement or the Prospectus which in the
       reasonable opinion of the 















<PAGE>

                                        14

       Representatives may be necessary to enable the several Underwriters to
       continue the distribution of the Stock and will use its best efforts to
       cause the same to become effective as promptly as possible.  

            (c)  If at any time after the effective date of the Registration
       Statement when a prospectus relating to the Stock is required to be
       delivered under the Securities Act any event relating to or affecting
       the Company or any of its subsidiaries occurs as a result of which the
       Prospectus or any other prospectus as then in effect would include an
       untrue statement of a material fact, or omit to state any material fact
       necessary to make the statements therein, in the light of the
       circumstances under which they were made, not misleading, or if it is
       necessary at any time to amend the Prospectus to comply with the
       Securities Act, the Company will promptly notify the Representatives
       thereof and will prepare an amended or supplemented prospectus which
       will correct such statement or omission; and in case any Underwriter is
       required to deliver a prospectus relating to the Stock nine (9) months
       or more after the effective date of the Registration Statement, the
       Company upon the request of the Representatives and at the expense of
       such Underwriter will prepare promptly such prospectus or prospectuses
       as may be necessary to permit compliance with the requirements of
       Section 10(a)(3) of the Securities Act.

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

            (e)  The Company will make generally available to its stockholders
       as soon as practicable, but not later than fifteen (15) months after the
       effective date of the Registration Statement, an earnings statement
       which will be in reasonable detail (but which need not be audited) and
       which will comply with Section 11(a) of the Securities 















<PAGE>

                                        15

       Act, covering a period of at least twelve (12) months beginning after
       the "effective date" (as defined in Rule 158 under the Securities Act)
       of the Registration Statement.

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

            (g)  The Company will furnish to its stockholders annual reports
       containing financial statements certified by independent public
       accountants and with quarterly summary financial information in
       reasonable detail which may be unaudited.  During the period of five (5)
       years from the date hereof, the Company will deliver to the
       Representatives and, upon request, to each of the other Underwriters,
       (i) as soon as is practicable after the end of each fiscal year, copies
       of each Annual Report of the Company filed on Form 10-K containing the
       balance sheet of the Company as of the close of such fiscal year and
       statements of income, stockholders' equity and cash flows for the year
       then ended and the opinion thereon of the Company's independent public
       accountants, (ii) as soon as they are available, copies of any other
       reports or communications of the Company (financial or other) which the
       Company shall publish or otherwise make available to any of its
       stockholders as such, (iii) as soon as practicable after the filing
       thereof, copies of each proxy statement, Quarterly Report on Form 10-Q,
       Report on Form 8-K or any report filed by the Company with the
       Commission, the NASD or any national securities exchange and (iv) from
       time to time such other information concerning the Company as the
       Representatives may reasonably request.  So long as the Company has
       active subsidiaries, such financial statements will be on a consolidated
       basis to the extent the accounts of the Company and its subsidiaries are
       consolidated in reports furnished to its stockholders generally.  













<PAGE>

                                        16

       Separate financial statements shall be furnished for all subsidiaries
       whose accounts are not consolidated but which at the time are
       significant subsidiaries as defined in the Rules and Regulations.

            (h)  The Company will have quoted, subject to official notice of
       issuance, on the Nasdaq National Market, the Stock to be issued and sold
       by the Company.

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

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

            (k)  Without the prior written consent of Cowen, the Company will
       not offer, sell, assign, transfer, encumber, contract or grant any
       option to purchase or otherwise dispose of any shares of Common Stock,
       options, rights or warrants to acquire shares of Common Stock, or
       securities exchangeable for or convertible into shares of Common Stock
       during the 180 days commencing on the date hereof, other than the
       Company's sale of Common Stock hereunder and the Company's issuance of
       Common Stock upon the exercise of warrants and stock options which are
       presently outstanding and described in the Prospectus, the Company's
       issuance of options under the Company's presently authorized stock
       option and purchase plans described in the Prospectus and the Company's
       issuance of Common Stock upon the exercise of any such options.

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

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

            (n)  Prior to the Closing Date, the Company will furnish to the
       Representatives, as soon as they have been prepared, copies of any
       unaudited interim consolidated financial statements of the Company and
       its subsidiaries for any periods subsequent to the periods covered by
       the financial statements appearing in the Registration Statement and the
       Prospectus.




















<PAGE>

                                        17


            (o)  Prior to the Closing Date, the Company will issue no press
       release or other communications directly or indirectly and hold no press
       conference with respect to the Company or any of its subsidiaries, the
       financial condition, results of operation, business, prospects, assets
       or liabilities of any of them, or the offering of the Stock, without the
       prior written consent of the Representatives.  For a period of twelve
       (12) months following the Closing Date, the Company will use its best
       efforts to provide to the Representatives copies of each press release
       or other public communications with respect to the financial condition,
       results of operations, business, prospects, assets or liabilities of the
       Company contemporaneously with the public issuance thereof.

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

            (b)  In addition to its other obligations under Section 5(a)
  hereof, the Company agrees that, as an interim measure during the pendency of
  any claim, action, investigation, inquiry or other proceeding arising out of
  or based upon (i) any statement or omission or any alleged statement or
  omission or (ii) any breach or inaccuracy in its representations and
  warranties, it will reimburse each Underwriter on a quarterly basis for all
  reasonable legal or other expenses incurred in connection with investigating
  or defending any such claim, action, investigation, inquiry or other
  proceeding, notwithstanding the absence of 













<PAGE>

                                        18

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

            (c)  In addition to its other obligations under Section 5(b)
  hereof, each Underwriter severally agrees that, as an interim measure during
  the pendency of any claim, action, investigation, inquiry or other proceeding
  arising out of or based upon any statement or omission, or any alleged
  statement or omission, described in Section 5(b) hereof which relates to
  written information regarding any Underwriter furnished to the Company by or
  on behalf of any Underwriter, directly or through you, specifically for use
  in the Registration Statement, it will reimburse the Company (and, to the
  extent applicable, each officer, director, or controlling person on a
  quarterly basis for all reasonable legal or other expenses incurred in
  connection with investigating or defending any such claim, action,
  investigation, inquiry or other proceeding, notwithstanding the absence of a
  judicial determination as to the propriety and enforceability of the
  Underwriters' obligation to reimburse the Company (and, to the extent
  applicable, each officer, director, or controlling person for such expenses
  and the possibility that such payments might later be held to have been
  improper by a court of competent jurisdiction.  To the extent that any such
  interim reimbursement payment is so held to have been improper, the Company
  (and, to the extent applicable, each officer, director, or controlling
  person) shall promptly return it to the Underwriters together with interest,
  compounded daily, determined on the basis of the Prime Rate.  Any such
  interim reimbursement payments which are not made to the Company within
  thirty (30) days of a request for reimbursement shall bear interest at the
  Prime Rate from the date of such request.  This indemnity agreement will be
  in addition to any liability which such Underwriter may otherwise have.

            (d)  It is agreed that any controversy arising out of the operation
  of the interim reimbursement arrangements set forth in paragraphs (b) and/or
  (c) of this Section 5, including the amounts of any requested reimbursement
  payments and the method of determining such amounts, shall be settled by
  arbitration conducted pursuant to the Code of Arbitration Procedure of the
  NASD.  Any such arbitration must be commenced by service of a written demand
  for arbitration or written notice of intention to arbitrate, therein electing
  the arbitration tribunal.  In the event the party demanding arbitration does
  not make such 














<PAGE>

                                        19

  designation of an arbitration tribunal in such demand or notice, then the
  party responding to said demand or notice is authorized to do so.  Such an
  arbitration would be limited to the operation of the interim reimbursement
  provisions contained in paragraphs (b) and/or (c) of this Section 5 and would
  not resolve the ultimate propriety or enforceability of the obligation to
  reimburse expenses which is created by the provisions of this Section 5.

            6.   Indemnification and Contribution.  (a)  The Company agrees to
                 --------------------------------
  indemnify and hold harmless each Underwriter and each person, if any, who
  controls such Underwriter within the meaning of the Securities Act and the
  respective officers, directors, partners, employees, representatives and
  agents of each of such Underwriter (collectively, the "Underwriter
  Indemnified Parties" and, each, an "Underwriter Indemnified Party"), against
  any losses, claims, damages, liabilities or expenses (including the
  reasonable cost of investigating and defending against any claims therefor
  and counsel fees incurred in connection therewith), joint or several, which
  may be based upon the Securities Act, or any other statute or at common law,
  on the ground or alleged ground that any Preeffective Prospectus, the
  Registration Statement or the Prospectus (or any Preeffective Prospectus, the
  Registration Statement or the Prospectus as from time to time amended or
  supplemented) includes or allegedly includes an untrue statement of a
  material fact or omits to state a material fact required to be stated therein
  or necessary in order to make the statements therein, in the light of the
  circumstances under which they were made, not misleading, unless such
  statement or omission was made in reliance upon, and in conformity with,
  written information regarding any Underwriter furnished to the Company by any
  Underwriter, directly or through the Representatives, specifically for use in
  the preparation thereof.  The Company will be entitled to participate at its
  own expense in the defense or, if it so elects, to assume the defense of any
  suit brought to enforce any such liability, but if the Company elects to
  assume the defense, such defense shall be conducted by counsel chosen by it. 
  In the event the Company elects to assume the defense of any such suit and
  retain such counsel, any Underwriter Indemnified Parties, defendant or
  defendants in the suit, may retain additional counsel but shall bear the fees
  and expenses of such counsel unless (i) the Company shall have specifically
  authorized the retaining of such counsel or (ii) the parties to such suit
  include any such Underwriter Indemnified Parties, and the Company and such
  Underwriter Indemnified Parties have been advised by counsel to the
  Underwriters that one or more legal defenses may be available to it or them
  which may not be available to the Company, in which case the Company shall
  not be entitled to assume the defense of such suit notwithstanding its
  obligation to bear the fees and expenses of such counsel.  This indemnity
  agreement is not exclusive and will be in addition to any liability which the
  Company might otherwise have and shall not limit any rights or remedies which
  may otherwise be available at law or in equity to each Underwriter
  Indemnified Party.

            (b)  Each Underwriter severally agrees to indemnify and hold
  harmless the Company, each of its directors, each of its officers who have
  signed the Registration Statement and each person, if any, who controls the
  Company within the meaning of the 













<PAGE>

                                        20

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

            (c)  If the indemnification provided for in this Section 6 is
  unavailable or insufficient to hold harmless an indemnified party under
  subsection (a) or (b) above in respect of any losses, claims, damages,
  liabilities or expenses (or actions in respect thereof) referred to herein,
  then each indemnifying party shall contribute to the amount paid or payable
  by such indemnified party as a result of such losses, claims, damages,
  liabilities or expenses (or actions in respect thereof) in such proportion as
  is appropriate to reflect the relative benefits received by the Company on
  the one hand and the Underwriters on the other 













<PAGE>

                                        21

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

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

       opinion of the Representatives, is required to be stated therein or is
       necessary to make the statements therein not misleading, or (ii) it is
       unpracticable in the reasonable judgment of the Representatives to
       proceed with the public offering or purchase the Stock as contemplated
       hereby.

       have been instituted or threatened and there shall have occurred no
       material adverse development in any existing such action, suit or
       proceeding.

  involving particularly the business or properties or securities of the
  Company or any of its subsidiaries or the transactions contemplated by this

  terms contemplated by the Prospectus.

            11.  Reimbursement of Underwriters.  Notwithstanding any other
                 -----------------------------
  provisions hereof, if this Agreement shall not become effective by reason of
  any election of the Company pursuant to the first paragraph of Section 10 or
  shall be terminated by the Representatives under Section 8 or Section 10, the
  Company will bear and pay the expenses specified in Section 5 hereof and, in

  Underwriters shall default in its or their obligations to purchase shares of
  Stock hereunder and the aggregate number of shares which such defaulting
  Underwriter or Underwriters agreed but failed to purchase does not exceed ten
  percent (10%) of the total number of shares underwritten, the other
  Underwriters shall be obligated severally, in proportion to their respective
  commitments hereunder, to purchase the shares which such defaulting
  Underwriter or Underwriters agreed but failed to purchase.  If any
  Underwriter or Underwriters shall so default and the aggregate number of
  shares with respect to which such default or defaults occur is more than ten
  percent (10%) of the total number of shares underwritten and arrangements
  satisfactory to the Representatives and the Company for the purchase of such

  shares by other persons are not made within forty-eight (48) hours after such
  default, this Agreement shall terminate.

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

            13.  Notices.  All communications hereunder shall be in writing

                 ----------
  be binding upon the several Underwriters, the Company and their respective

  Act, and the indemnities of the several Underwriters shall also be for the

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


  Ladies and Gentlemen:

            We have acted as counsel to Advanced Health Corporation, a Delaware
  corporation (the "Company"), in connection with the issuance and sale by the
  Company of an aggregate of _____________ shares of the Company's  Common
  Stock, par value $.01 per share (the "Shares"), to the Underwriters named in
  Schedule I of the Underwriting Agreement dated October [__], 1996 (the
  "Underwriting Agreement") among the Company and Cowen & Company and Volpe,
  Welty & Company, as representatives of the several Underwriters.  This
  opinion is being delivered to you pursuant to Section 8(f) of the
  Underwriting Agreement.  Capitalized terms used but not defined herein shall
  have the meanings ascribed thereto in the Underwriting Agreement. 

            In this capacity, we have examined signed copies of the
  registration statement on Form S-1 (Registration No. 333-06283) (the
  "Registration Statement") filed by the Company  under the Securities Act of
  1933, as amended, (the "Securities Act") with the Securities and Exchange
  Commission (the "Commission") on June 19, 1996, Amendment No. 1 to the
  Registration Statement filed with the Commission on August 15, 1996 and
  Amendment No. 2 to the Registration Statement filed with the Commission on
  September 9, 1996.  The Registration Statement, as amended at the time it
  became effective, including the information deemed to be a part thereof at
  the time of effectiveness pursuant to Rule 430A under the Securities Act, the
  exhibits and the schedules thereto, is hereinafter referred to as the
  "Registration Statement," and the final prospectus dated October [__], 1996,
  in the form filed by the Company pursuant to Rule 424(b)(4) under the
  Securities Act, is hereinafter referred to as the "Prospectus."

            We have also examined the Underwriting Agreement and the originals,
  or copies identified to our satisfaction, of such corporate records of the
  Company, certificates of public officials, officers of the Company and other
  persons, and such other documents,

  agreements and instruments as we have deemed necessary as a basis for the
  opinions hereinafter expressed.  In such examination, we have assumed the
  genuineness of all signatures, the authenticity of all documents submitted to
  us as originals and the conformity with the originals of all documents
  submitted to us as copies.  In rendering the opinions expressed below, we
  have relied as to certain factual matters, to the extent we deem proper, upon
  the representations and warranties contained in or made pursuant to the
  Underwriting Agreement and upon certificates of officers of the Company and
  certificates of public officials.

            With respect to our opinion set forth in Paragraph (ii) below, we
  have relied upon and assumed the accuracy of telephonic confirmation from the
  Staff of the Division of Corporation Finance of the Commission that the
  Registration Statement has become and remains effective under the Securities
  Act. 

            Our opinions expressed below are limited to the law of the State of
  New York, the General Corporation Law of the State of Delaware and the
  Federal Law of the United States, and we do not express any opinion herein
  concerning any other law.

            Based upon and subject to the foregoing, we are of the opinion
  that:

            (i)  Each of the Company has and its subsidiaries has been duly
  organized and is validly existing and in good standing as a corporation under
  the law of its respective jurisdictions of organization, with full corporate
  power and authority to own or lease its properties and to conduct its
  business as described in the Prospectus;

            (ii) The Registration Statement has been declared effective under
  the Securities Act and no stop order suspending the effectiveness of the
  Registration Statement has been issued, and to the best of our knowledge, no
  proceedings for that purpose have been instituted or are pending or
  contemplated under the Securities Act;

            (iii)     The description of all contracts and other documents
  referred to in the Registration Statement and the Prospectus, and the
  summaries of, and other disclosures regarding, such contracts and other
  documents included in the Registration Statement and the Prospectus fairly
  present the information required to be disclosed with respect thereto; and,
  to our knowledge, there are no other contracts or other documents of a
  character required to be filed as an exhibit to the Registration Statement
  or required to be described in the Registration Statement or the Prospectus
  which are not filed or described as required;

            (iv) The Underwriting Agreement has been duly authorized, executed
  and delivered by the Company;
















<PAGE>

                                         3


                 (v)   The authorized capital stock of the Company conforms in
    all material respects as to legal matters to the description thereof
    contained in the Prospectus;

                 (vi)  The Shares have been duly authorized, and when delivered
    to and paid for by the Underwriters in accordance with the terms of the
    Underwriting Agreement, will be validly issued, fully paid and non-
    assessable and the issuance of the Shares is not subject to any preemptive
    or similar rights;

                 (vii)  All registration rights attached to any of the
    Company's shares have been duly waived with respect to the offering
    contemplated by the Prospectus;

                 (viii) The issue and sale of the Shares and the performance
    by the Company of its obligations under the Underwriting Agreement will not
    result in any violation of the certificate of incorporation or by-laws of
    the Company or the provisions of the General Corporation Law of the State
    of Delaware or any applicable New York or Federal law or statute or any
    order, rule or regulation of any New York or Federal court or governmental
    agency or body having jurisdiction over the Company or any of its
    properties (except that we render no opinion herein with respect to the
    compliance of the indemnification or contribution provisions of the
    Underwriting Agreement with the Federal Securities law;

                 (ix)   To the best of our knowledge, the execution, delivery 
    and performance of the Underwriting Agreement and the consummation of the
    transactions therein contemplated will not result in a breach or violation
    of any of the terms or provisions of any material agreement or instrument
    to which the Company or any of its subsidiaries is a party or by which it
    or any of its properties is bound or result in the creation of a lien under
    any of such agreement; 

                 (x)    No consent, approval, authorization, order, registration
    or qualification of or with any New York or Federal court or governmental
    agency or body is required for the sale and issuance of the Shares or the
    performance of the Company of its obligations under the Underwriting
    Agreement, except such consents, approvals, authorizations, registrations
    or qualifications as have been obtained under the Securities Act, as may be
    required under state securities or Blue Sky laws or under the rules of the
    National Association of Securities Dealers, Inc. in connection with the
    purchase and distribution of the Shares by the Underwriters.

                 (xi)   The Company and its subsidiaries are in all material
    respects in compliance with, and conduct their businesses in conformity
    with, all applicable federal, state, local and foreign laws, rules and
    regulations of any court or governmental agency or body; otherwise than as
    set forth in the Registration Statement and the Prospectus, no prospective
    change in any of such federal or state laws, rules or regulations has been

                                         4

    adopted which, when made effective, would have a material adverse effect on
    the operations of the Company and its subsidiaries;

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

                 (xiii)    To the best of our knowledge, except as set forth in
    the Prospectus, there are no legal or governmental proceedings pending to
    which the Company or any of its subsidiaries or affiliates is a party or of
    which any property of the Company or any subsidiary or affiliate is
    subject, which, if determined adversely to the Company or any such
    subsidiary or affiliate, might individually or in the aggregate (i) prevent
    or adversely affect the transactions contemplated by the Underwriting
    Agreement, (ii) suspend the effectiveness of the Registration Statement,
    (iii) prevent or suspend the use of the Prospectus in any jurisdiction or
    (iv) result in a material adverse change in the condition (financial or
    otherwise), properties, business, management, prospects, net worth or
    results of operations of the Company and its subsidiaries considered as a
    whole; and to the best of our knowledge, no such proceedings are threatened
    or contemplated against the Company or any subsidiary or affiliate by
    governmental authorities or others.  

                 (xiv)     Neither the Company nor its subsidiaries is an
    "investment company" or an entity "controlled" by an "investment company"
    as such terms are defined in the Investment Company Act of 1940, as
    amended;

                 (xv)      The statements in the Prospectus under the caption
    "Description of Capital Stock" and "Shares Eligible for Future Sale", 
    insofar as such statements constitute a summary of documents referred to 
    therein or matters of law, are accurate summaries and fairly and correctly 
    present, in all material respects, the information called for with respect 
    to such documents and matters; and

                 (xvi)     The Registration Statement and the Prospectus (except
    for the financial statements, notes thereto and other financial information 
    and schedules included therein or omitted therefrom as to which we have not 
    been requested to express any opinion) appear on their face to have been
    appropriately responsive in all material respects to the requirements of the
    Securities Act.

            We have not verified, and are not passing upon and do not assume
  any responsibility for, the accuracy, completeness or fairness of the
  statements contained in the Registration Statement or Prospectus, other than
  those mentioned in subparagraph (xv)

  above.  We have, however, generally reviewed and discussed such statements
  with certain officers of the Company, its auditors and with your
  representatives and their counsel.  In the course of this review and
  discussion, no facts have come to our attention that lead us to believe that
  (i) the Registration Statement (except for the financial statements, notes
  thereto and other financial information and schedules included therein or
  omitted therefrom as to which we have not been requested to express any
  opinion or statement of belief), at the time the Registration Statement
  became effective, contained any untrue statement of a material fact or
  omitted to state a material fact required to be stated therein or necessary
  to make the statements therein not misleading, or (ii) the Prospectus (except
  for the financial statements, notes thereto and other financial information
  and schedules included therein or omitted therefrom as to which we have not
  been requested to express any opinion or statement of belief), at the time
  the Prospectus was issued or on the date hereof, contained any untrue
  statement of a material fact or omitted to state a material fact necessary in
  order to make the statements therein, in the light of the circumstances under
  which they were made, not misleading.

           ----------------------------
title to its property and assets free and clear of all mortgages, liens, loans,

of such property or assets.  With respect to the property and assets it leases,
the Company is in compliance with such leases and, to its knowledge, holds a
valid leasehold interest free of any liens, claims, or encumbrances.  All of the

           -----------------------------------------------
bound by or subject to (and none of its assets or properties is bound by or

arrangement with any labor union, and no labor union has requested or, to the

representatives, or agents of the Company.  There is no strike or other labor
dispute involving the Company pending, or, to the knowledge of the Company,
threatened, which could have a material adverse effect on the assets,
properties, financial condition, operating results, or business of the Company

(and all such returns are true and correct and fairly reflect its operations for
tax purposes); and (ii) has timely paid all taxes owed or assessments by it
(other than taxes the validity of which are being contested in good faith by
appropriate proceedings).  The assessment of any additional taxes for periods
for which returns have been filed is not expected to exceed the recorded
liability therefor and, to the Company's knowledge, there are no material
unresolved questions or claims concerning the Company's tax liability.  The
Company's tax returns have not been reviewed or audited by any taxing authority.
There is no pending dispute with any taxing authority relating to any of said
returns which, if determined adversely to the Company, would result in the
assertion by any taxing authority of any valid deficiency in a material amount
for taxes.

IDM so notifies MES in writing within the applicable fifteen (15) day period,
MES and IDM shall negotiate in good faith for thirty (30) days in order to
conclude a mutually acceptable cash purchase price and a definitive agreement
with respect to the acquisition of the Marketing Rights by IDM. If MES and IDM
fail to enter into a definitive agreement with respect to the Marketing Rights
within thirty (30) days after the date IDM notifies MES of its intention to
exercise its Right of First Offer, each party shall deliver to the other a
written instrument setting forth in the case of IDM, the highest price offered
to MES during the prior negotiation period and, in

                                      -20-
<PAGE>

the case of MES, the lowest offer price MES indicated to IDM that MES would
accept during the prior negotiation period for the Marketing Rights. Once such
written instruments have been delivered an acquisition price shall be calculated
by the Coordinating Committee taking the average of the prices set forth by IDM
and MES in such written instruments (the "Strike Price"). If MES offers the
Marketing Rights to any other non-Affiliate third party at a price lower than
the Strike Price, IDM shall have a right to acquire the exclusive marketing
rights from MES at such lower price within a fifteen (15) day period following
MES's written notice to IDM of such offer. If MES negotiates a price with
another party for the Marketing Rights at or above the Strike Price, MES may
freely license, assign or transfer the Marketing Rights to such party. The
parties agree that the foregoing rights of IDM set forth in this Section 7.3
shall not preclude an MES customer from installing its own or any third party's
disease management applications on the Med-E-Practice System platform it is
using. If IDM fails to notify MES within fifteen (15) days of its desire to
exercise its Right of First Offer, MES shall be free to assign or transfer the
Marketing Rights to any third party.

     7.4 IDM Right to Offer Its Customer the Med-E- Practice System. During the
Term, if IDM identifies a customer (other than the two customers involved in the
Pilots) interested in an IDM disease management application program utilizing
the Med-E-Practice System platform, IDM may offer MES's products and services
relating thereto with the prior written consent of MES,



                                      -21-
<PAGE>

such consent not to be unreasonably withheld. IDM shall notify MES in writing of
such customer's desire to acquire the joint products and services of IDM and MES
and within ten (10) days of receipt of such notice, MES shall respond to IDM in
writing. If MES does not respond within such ten (10) day period, MES shall be
deemed to have agreed to provide the requested services at its standard rates.

     7.5 Pilot Results. Notwithstanding their Joint Ownership Interest in and to
the Pilot Results, IDM and MES shall each have the right to access and use the
Pilot Results in connection with the marketing of their respective products,
subject to any restrictions placed upon such access and use by IDM's customers
participating in such Pilots.

     7.6 Future Beta Releases of MES Products. MES agrees that it will offer to
IDM and IDM's customers which have the Med-E-Practice System, the opportunity to
participate in any future beta releases of MES products, including both hardware
and software products, on terms to be mutually agreed by the parties (which
terms will be comparable to those offered to other third parties), provided,
however, that IDM and such customers first enter into non-disclosure and
confidentiality agreements relating thereto in form and substance satisfactory
to MES.

     7.7 Export Controls. In connection with any marketing activities undertaken
by the parties hereunder, the parties acknowledge that the Med-E-Practice
System, the Service Interface and Pilot Results and the Confidential Information
relating thereto (the "Technical Data") may be subject to United 



                                      -22-

C.F.R. Parts 768-799. The parties agree to comply strictly with any and all
requirements of the Export Administration Regulations with respect to all such
Technical Data and to cause their customers to comply with the same. MES shall
use reasonable commercial efforts to respond to any questions IDM may receive
from its managed care customers.

     7.8 Use of Trademarks. (a) MES hereby grants to IDM a non-exclusive,
worldwide, fully paid-up license during the term of this Agreement to display
the MES Trademarks specified by MES to IDM as reasonably determined by MES for
use on materials ap- proved by MES in connection with any marketing of the
Med-E- Practice System hereunder. The use of any MES Trademark by IDM shall be
subject to prior approval by MES in writing and to compliance with such
specifications concerning the graphics, color and other distinctive features of
such MES Trademarks as may reasonably be determined by MES.

     (b) IDM hereby grants to MES a non-exclusive, worldwide, fully paid-up
license during the term of this Agreement to display the IDM Trademarks
specified by IDM to MES as reasonably determined by IDM for use on materials
approved by IDM in connection with any marketing hereunder. The use of any IDM
Trademarks by MES shall be subject to prior approval by IDM in writing and to
compliance with such specifications concerning the graphics, color and other

                      MES Scope of Services for the Pilots


          MES will provide the MEP system for 2 Pilot sites at a cost of
 [    ]* per Pilot site.

          For each Pilot Site, MES will  provide the minimum necessary
resources, services, hardware and software to:

          -    Support up to 50 physicians (one computer tablet per physician)
               practicing in up to a total of 4 physically separate locations,
               including a total of 7 administrative/print stations to serve the
               50 physicians.  Hardware and software configuration includes:

               -    Physician hardware - a Fujitsu Stylistic 500 with 8 mg of
                    RAM, 170 mg hard drive, and a Proxim radio frequency modem,
                    or compatible hardware configuration.

               -    Adminsitrative/print station hardware - a 486 Personal
                    Computer, an Inkjet Printer, a radio frequency base station
                    (e.g. Proxim's Access Point) and other equipment required
                    for communications with the Med-E-Net server.

               -    Med-E-Practice Applications:  SmartScripts, Med-E-Visit,
                    Med-E-Referral, and Med-E-Mail (facilitates connectivity
                    between physicians)

          -    Obtain from the Pilot site's practice management system (PMS) an
               initial patient roster load to MEP.  Provide the administrative
               workstation functionality to add and maintain patients.  The
               initial patient roster will be loaded onto MEP under the above
               cost provided that, as expected, the patient information can be
               obtained from the physician's practice management system in an
               electronic format.  Acceptable electronic formats include
               ANSI X.12 eligibility and patient roster records, and HL7 patient

               interface between its host server and the PBM's host.  IDM and
               the customer managed care organization bear the responsibility of
               gaining the permission and cooperation from the PBM to allow for
               this connection to be made.  IDM must notify MES that it has
               received consent from the PBM for the connection.

          -    Load a formulary database and referral network database for the
               customer managed care organization.  MES will offer a mechanism

               Calls on the toll-free line will be answered during the hours of
               7:30 a.m. to 7 p.m. Central Time, Monday through Friday (except

               the Connection Date for the first pilot.

At IDM's request, MES will provide additional computer tablets for patient use
at an approximate additional cost of [    ]* per unit, which includes the cost
of maintenance and service during the pilot year.  Additional services beyond

must clearly state that the Licensee is acting under license from the Licensor;

     (b) such sublicense, and any further sublicense permitted by this Section,
(A) shall terminate no later than 180 days after the sublicensee thereunder
ceases to be a Permitted Sublicensee, (B) must contain provisions to ensure that
all communications functions of such Product, other than the electronic

the electronic prescription transmission, are used solely for direct or indirect
communications to or from the Licensee regarding patients covered by a program
or service provided by the Licensee, and (C) must provide that the sublicensee


                                      -8-

thereunder may not further sublicense such Product to any person or entity,
other than any Permitted Sublicensee;

     (c) any permitted further sublicense (A) must be made in accordance with,
and contain provisions to ensure compliance with, Sections 4.2, 4.3, 4.4, 4.5,
4.6, and 6.2 of this Agreement and (B) must contain an obligation, to the extent
permitted by any other bona fide contractual obligation, to notify the Licensee
of any further sublicense and the name of the parties thereto; and

     (d) if such Product is provided as source code, such source code (A) may
not be used by such Permitted Sublicensee or any further Permitted Sublicensee
for any purpose other than the integration of such Product into any Integrated

employees of such Permitted Sublicensee or further Permitted Sublicensee that
have a predetermined need to know such source code.

     (b) To the extent permitted by any bona fide contractual obligation to
third parties, the Licensee shall promptly (i) notify the Licensor of any

the Licensor to physicians for the Licensor's Products.

     In connection with the distribution and sublicensing of Products, the
Licensee shall take all reasonable steps and use all reasonable efforts
necessary in order to protect the Licensor's Intellectual Property Rights
relating to the Program. The Licensee shall notify the Licensor of any
threatened or actual infringement of any Intellectual Property Right of the
Licensor promptly after the Licensee obtains knowledge thereof. Nothing
contained herein shall be construed to limit in any way the right of the
Licensor to take at any time all actions and use all efforts as the Licensor, in
its sole discretion, may deem necessary to detect any infringement of any
Intellectual Property Right of the Licensor, to enjoin such infringement and
recover damages therefor, and otherwise protect all Intellectual Property Rights

4.7. Beta Version.

     Upon completion of the beta version of any Product made or manufactured by
the Licensee, the Licensee shall, to the extent permitted by any contractual
obligation to third parties, provide a copy of such beta version to the Licensor
upon the same terms and conditions as such beta version is generally made
available for beta testing. The provision by the Licensee of any such beta
version shall not constitute a license to the Licensor with respect to such
Product. If any contractual obligation to third parties prohibits the Licensee
from providing a copy of such beta version to the Licensor, the Licensee shall
represent and warrant that the Licensee has taken reasonable steps to assure the
proper functioning of the Product.

4.8. Outsourcing of Development. 

     Subject to the terms and conditions of this Section and Section 6.1, the
Licensee may at any time engage any independent contractor for the development
of any Modification or Enhancement. Any such independent contractor may not be
engaged in any Competitive Business. If the Licensee proposes to engage any
independent contractor for the development of any Modification or Enhancement,
other than any individual who performs his or her services in connection with
and as part of internal development by the Licensee or any entity that furnishes
such individuals on a temporary basis, the Licensee shall, before such
engagement, deliver to the Licensor an offer to perform such development. Such
offer shall describe in reasonable detail the development to be performed and
state the terms of (including fees for) the proposed engagement. The Licensor
may accept such offer within 15 days of such delivery. If the Licensor does not
accept such offer within such 15-day period, the Licensee may engage any third
party on the terms of such offer within 12 months after expiration of such
15-day period. If such engagement is not made within such 12-month period, the
restrictions provided for in this Section shall again become effective.

4.9. Termination.

     The obligations of the Licensee under Sections 4.7 and 4.8 shall terminate
upon the earliest to occur of (i) the bankruptcy of the Licensor, (ii) the
acquisition by any person or entity principally engaged in the provision of
services competitive to services from which the Licensee derives substantial
revenues of (A) all or substantially all assets of the Licensor or (B) a
majority of the capital stock of the Licensor entitled to vote for the election
of directors, and (iii)(x) with respect to Section 4.7, the second anniversary
of the termination of the Upgrade Period, and (y) with respect to Section 4.8,
the termination of the Upgrade Period.

preclude assertion of any other rights or the seeking of any other remedies.

                       CONFIDENTIALITY AND NONCOMPETITION

6.1. Confidentiality

     (a) "Confidential Information" means all materials and information in
whatever form disclosed by either party to the other party in connection with
the performance of this Agreement that was identified to be confidential or
proprietary in nature or, from the nature thereof or the circumstances under
which disclosed, should reasonably be regarded as confidential or proprietary
information; provided, however, that "Confidential Information" shall not
include information that is:

          (i) available to the general public or to the software development
     industry generally;

          (ii) lawfully received by either party from a third person who, to the
     knowledge of such receiving party, is or was not bound in a confidential
     relationship to the disclosing party;

          (iii) already in the possession of the receiving party without
     obligation to the other party to keep such information confidential;

          (iv) necessary for the purpose of enforcement of this Agreement; or



                                      -12-
<PAGE>

          (v) required by law to be disclosed.

     (b) Either party receiving Confidential Information (i) shall limit the
disclosure, publication or dissemination of such Confidential Information to
those employees or independent contractors of such party that have a
predetermined need to know (or could reasonably be expected to need to know it
for the purposes of this Agreement), (ii) shall advise such employees and
independent contractors of the confidential nature of such Confidential
Information, (iii) shall require any such independent contractors to acknowledge
the restrictions set forth in this Section in writing, and (iv) shall use the
same care and discretion to avoid disclosure, publication or dissemination of
such Confidential Information outside of such employees and independent
contractors as such party employs with similar information of its own which it
does not desire to publish, disclose or disseminate.

     (c) Subject to the licenses granted under this Agreement, all tangible
forms of Confidential Information shall remain the property of the disclosing
party and the receiving party shall promptly return to the disclosing party or
destroy such Confidential Information upon the written request of the disclosing
party. 

     (d) Nothing contained herein shall prevent either party from disclosing any
Confidential Information in compliance with a valid order of a court or other
governmental entity of the United States; provided, however, that the party
making the disclosure in compliance with such order shall first have given
notice to the other party and made a reasonable effort to obtain a protective
order requiring that any disclosed Confidential Information be used only for the
purposes for which such order was issued.

6.2. Noncompetition. 

     The Licensee acknowledges that the licenses granted under this Agreement
will allow the Licensee to acquire particular familiarity with the Program and
the Licensor's business of developing and selling computerized patient records
systems. Accordingly, the Licensee shall not (i) use the Program, including any
Modification or Enhancement, in connection with the engagement in any
Competitive Business, (ii) during the Upgrade Period and for two years
thereafter, induce any person employed by the Licensor to terminate his or her
employment with the Licensor, or (iii) during the Upgrade Period (and, if the
Upgrade Period has been terminated upon delivery of a notice under Section 7.3,
for two years thereafter, unless given in connection with a notice under Section
7.2(a) that the Licensee is engaged in a Competitive Business, in which case
such additional period shall be 60 days) specifically solicit any customer or
supplier of the Licensor to replace its relationship with the Licensor with a
substantially similar relationship with the Licensee.


                                      -13-
<PAGE>

Nothing contained in this Section shall prohibit the Licensee from (A) engaging
in any Competitive Business, (B) investing in or entering into a business
relationship with any person or entity engaged in a Competitive Business, and
(C) manufacturing, marketing, distributing, and sublicensing Products in
accordance with this Agreement; provided, however, that (x) the Licensee may not
use the Program in connection with the engagement in any Competitive Business,
and (y) if the Licensee engages in any Competitive Business, other than in the
form of an investment in or business relationship with any person or entity so
long as the Licensee does not control the management of such person or entity,
Section 7.2(a) shall apply. 

6.3. Limited Exclusivity.

grant any license substantially similar to the licenses granted under this
Agreement to PCS Health Systems, Inc.; Diversified Pharmaceutical Services,
Inc.; Value Health, Inc.; Caremark International Inc.; or any affiliate of any
of the foregoing.

6.4. Remedies. 

     In the event of a breach or threatened breach by either party of any

restrain such actual or threatened breach. Such party may also pursue any other
remedies (including, without limitation, an action for damages) available for
such actual or threatened breach.

                                   ARTICLE VII

                                   TERMINATION

7.1. Term of Licenses.

     Except as set forth in this Article VII, the licenses granted to the
Licensee under this Agreement shall be perpetual and non-terminable. Termination
of the licenses granted hereunder shall not be available to the Licensor as a
remedy for the breach of this Agreement by the Licensee. The Licensor's
bankruptcy or insolvency shall not terminate or permit the Licensor or its
trustee in bankruptcy to terminate the licenses granted hereunder.

7.2. Termination After Competition.

     (a) Promptly upon engaging in any Competitive Business, the Licensee shall
deliver a notice to the Licensor describing such engagement, including the date
of its commencement, in reasonable detail. Within 60 days after the delivery of
such


                                      -14-
<PAGE>

notice, the Licensor may terminate this Agreement to the extent set forth in
paragraph (b) below by notice delivered to the Licensee, which notice shall
become effective immediately. The foregoing right of termination shall not apply
if such engagement consists solely of an investment in or business relationship
with a person or entity engaged in a Competitive Business, so long as the
Licensee does not control the management of such person or entity.

     (b) Upon any termination of this Agreement in accordance with paragraph (a)
above, the licenses to use Modifications and Enhancements developed by or on
behalf of the Licensor after the date of such termination, and to use the
Trademarks, shall terminate. Any such termination shall not affect (i) the
license to use the Program, and all Modifications and Enhancements developed by
or on behalf of the Licensor prior to the date of such termination, in
accordance with this Agreement, (ii) all sublicenses of Products granted prior
to such termination, (iii) the obligation of the Licensee with respect to such
sublicenses under Article IV, and (iv) the provisions of Articles V and VI, all
of which shall survive such termination.

7.3. Termination for Modifications and Enhancements. 

     By notice to the Licensor, the Licensee may terminate its right to receive
and use Modifications and Enhancements developed by or on behalf of the Licensor
after the date of such termination, but any such termination shall not affect
the license to use the Program, and all Modifications and Enhancements developed
by or on behalf of the Licensor prior to the date of such termination, in
accordance with this Agreement.

                                  ARTICLE VIII

respect to its subject matter. This Agreement supersedes all prior agreements
and understandings between the parties with respect to its subject matter.

                                [PRINTED MATERIAL SEQUENTIALLY NUMBERED (LINES)]

             TERMS AND CONDITIONS - SYSTEM IMPLEMENTATION AGREEMENT

1. DELIVERY IDX shall arrange for shipment of Hardware by common carrier at
mutually agreeable time(s). Customer shall pay or reimburse IDX for all costs of
Hardware shipping, and transportation. Good and merchantable title and risk of
loss in and to the Hardware shall pass to Customer upon delivery of each
respective item to the common carrier. At Customer's expense, IDX shall procure
transit and casualty insurance for the replacement value of the Hardware,
covering the transportation of the Hardware by the common carriers to Customer's
loading dock. Upon delivery, IDX shall install all those items designated on the
Hardware Schedule as to be installed by Customer. Upon successful installation
of the items of Hardware necessary to install the Software, IDX shall install
the object code version of the Software and notify Customer that the Software
has been installed.

2. OTHER TERMS Terms, conditions and warranties applicable to the Hardware and
operating system software and to all other products not manufactured by IDX are
provided by the applicable manufacturers, as set forth on the Manufacturer's
Supplement attached hereto. IDX makes no warranty as to the Hardware and no
warranty as to any other products not manufactured by IDX.

3. CHARGES AND PAYMENT Customer agrees to pay the charges specified in the
schedules and supplements hereto as and when due and shall pay a finance charge
equal to one and one-half percent (1 1/2%) per month on all amounts not paid
within thirty (30) days from the date of invoice. Customer shall pay or
reimburse IDX for all reasonable out-of-pocket expenses in connection with
delivery and installation of the Hardware and Software, including travel,
lodging and meals. All travel will be coach or tourist class. Prices and fees
are exclusive of all federal, state, municipal, or other government excise,
sales, use, occupational, or like taxes now in force or enacted in the future,
and Customer agrees to pay any tax (excluding taxes on IDX's net income) which
IDX may be required to collect or pay now or at any time in the future and which
are imposed upon the sale or delivery of items and services purchased or
licensed hereunder. Customer's obligation to pay taxes shall include interest
imposed by taxing authorities on uncollected taxes at a rate not greater than
the Citibank prime rate plus three percent (3%) and penalties imposed by any
taxing authorities to the extent such penalties are applicable to taxes not paid
at the request of Customer, or as a result of reliance by IDX on representations
of Customer. If a certificate of exemption or similar document or proceeding is
necessary in order to exempt the sale from sales or use tax liability, the
Customer will obtain and pursue such certificate, document or proceeding.
Customer will be charged and agrees to pay, at IDX's then current rate, for all
goods and services not specified herein or on the included supplements,
schedules and attachments and which are requested by Customer.

[PARAGRAPH 4 DELETED AND INITIALED: is JC]

5. GRANT OF LICENSE Subject to all the terms and conditions of this Agreement,
IDX hereby grants to Customer, and Customer hereby accepts, a personal,
non-exclusive, non-transferable, term license to use, only as herein provided,
one (1) executable copy of the object code version of the Software and two (2)
copies of the database to be created with the Software, one (1) of which shall
be dedicated only to testing and training purposes, and one (1) of which may be
used for Customer's data processing purposes. IDX also grants to Customer such a
license to use, as a reference and training aid for Customer in its licensed use
of the Software, one (1) copy of the applicable IDX standard published
instruction and operating manuals furnished to Customer by IDX from time to time
("Documentation"). IDX reserves all rights, title, privileges and interests not
expressly granted to Customer, who shall acquire no right, title, interest or
privilege with respect to the Software or the Documentation by implication. The
term of the license herein granted is ten (10) years commencing with the
effective date of this Agreement unless terminated earlier as provided herein.

6. SCOPE OF LICENSE The one (1) executable copy of the object code version of
the Software and two (2) executable copies of the data base licensed herein may
be used by Customer for processing of data on the Hardware or any temporary
substitution located in the United States, but not so as to serve more than the
number of terminals indicated in the box on the first page of this Agreement.
For the purpose of the preceding sentence, the term "terminals" refers to any
kind of local or remote data entry or inquiry device. Terminals may be counted
by the Software, and it may operate to deny Software access to an end user or
deny operation of a process initiated at any terminal, to the extent that such
access or use would result in more


<PAGE>


than the number of terminals specified on the front page of this Agreement. The
data processed by Customer shall be strictly limited to data created or used in
Customer's business as a licensed provider of medical care, and no other data of
any other person or entity. Neither the Software nor the Documentation may be
used in any manner directly or indirectly related to or in connection with the
operation or management of any other business, including without limitation a
timeshare, facilities management, practice management billing or data processing
service. Customer may not modify or sublicense the Software. Customer may make
and keep up to two (2) back-up copies of the Software, provided Customer employs
secure back-up procedures and a secure location in the United States, and
provided further that Customer shall place on such copy any proprietary notice,
including, copyright notice, requested by IDX.

7. TITLE AND OWNERSHIP IDX is the exclusive owner, or sublicensor, of the
Software, the Documentation and all associated materials provided to Customer,
all modifications, additions, derivatives and enhancements thereof, all copies
thereof and all rights therein. All modifications, additions, derivatives and
enhancements to the Software and Documentation shall be deemed a part of the
Software. Physical copies of Software and Documentation are not sold to
Customer, but are the property of IDX and are provided to Customer on loan
during the term of this Agreement. Customer shall keep each and every copy of
the Software, and all rights and interests therein, licensed hereunder free and
clear of all claims, liens and encumbrances, and any act of Customer purporting
to create such a claim, lien or encumbrance shall be void. Customer acknowledges
IDX's representation that the Software, Documentation and related materials,
techniques and procedures contained herein embody valuable trade secrets.
Customer shall not create or attempt to create, by decompilation, disassembly,
reverse engineering or otherwise, the source programs for the Software from the
object programs or other information made available by IDX, nor shall Customer
demonstrate, disclose, divulge, communicate or allow access to the Software, the
Documentation or any portion thereof to any person (including contractors and
consultants), except to Customer's employees, but then only to the extent
necessary to operate the Software as licensed hereunder.

8. CUSTOMER RESPONSIBILITIES Customer shall be responsible for timely site
preparation, including without limitation power, environment and cabling not
specifically to be provided by IDX, and shall prepare for and assist IDX in
timely installation of the Hardware and the Software. Customer shall use its
best efforts to implement the Software which shall include making available a
sufficient number of qualified personnel to be trained by IDX in the use,
operation, and management of the Hardware and Software, and providing and
adequately managing the resources necessary to test, implement and operate the
Hardware and Software, completing IDX start-up questionnaires, selecting among
options and parameters, and constructing data dictionaries. IDX shall not be
responsible for use of Hardware and Software if not operated in a manner
recommended in the Documentation, nor shall IDX be responsible for any
non-compliance by Customer with laws, or failure to use audit controls, back-up
and security procedures. IDX is not responsible for any failure by Customer to
use professional care in the use and validation of the results produced by the
Hardware and Software. Customer shall indemnify and hold harmless IDX, its
officers, directors, employees, successors and assigns from and against any and
all claims, liabilities, costs and damages arising out of or in any manner
connected with Customer's medical malpractice.

9. ACCEPTANCE The Software shall be deemed accepted when Customer has used the
Software to produce output not in a test mode for a period of thirty (30) days.

10. LIMITED WARRANTY IDX warrants only that, when operated as recommended, each
module or unit of the Software will perform substantially as described in the
current editions of the Documentation for a warranty period commencing on the
date IDX gives notice that the Software has been installed and is ready for
productive use and continuing for ninety (90) days thereafter (the "Warranty
Period"). IDX will perform technical services at no cost to Customer, to design,
code, check out and deliver promptly amendments or alterations to Software, or
other solutions, necessary to remedy or avoid any condition which causes the
Software to fail to perform as warranted above. Customer shall allow Software
access to IDX through dedicated remote communications for this purpose. The
foregoing is Customer's sole and exclusive warranty of performance regarding the
Software, and Customer's sole and exclusive remedy for breach of such limited
warranty. This limited warranty is contingent upon Customer's written report,
received not later than five (5) days after the last day of the Warranty Period,
detailing the nature and circumstances of any alleged breach of warranty.

11. CUSTOMER ACKNOWLEDGES THAT NO EXPRESS WARRANTIES HAVE BEEN MADE BY IDX
EXCEPT FOR THE LIMITED WARRANTY MADE IN THE FOREGOING ENTITLED "LIMITED
WARRANTY." THIS LIMITED WARRANTY AND THE ASSOCIATED LIMITED REMEDY ARE PROVIDED
BY IDX IN LIEU OF ALL OTHER WARRANTIES AND REMEDIES RELATED TO PERFORMANCE OF
THE SOFTWARE AND HARDWARE. IDX DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

12. BANKRUPTCY All rights and licenses granted under or pursuant to this
Agreement by IDX to Customer are, and shall otherwise be deemed to be, for
purposes of Section 365(n) of the United States Bankruptcy Code (the "Code"),
licenses to rights to "intellectual property" as defined under Section 101(52)
of the Code. Customer, as licensee of such rights under this Agreement, shall
retain and may fully exercise all of its rights and elections under the Code. In
the event of the commencement


<PAGE>


of a bankruptcy proceeding by or against IDX under the Code, Customer shall be
entitled to retain all of its rights under this License.

13. ASSIGNMENT This Agreement shall be binding upon and shall inure to the
benefit of the parties hereto and their respective successors and permitted
assigns. Neither this Agreement nor any of the rights hereunder may be assigned,
sold or otherwise transferred by a party without the prior express written
consent of the other, except that after the expiration of the Warranty Period,
there shall be no restriction upon assignment of this Agreement by IDX. The
obligations of IDX under Section 14 below shall not be terminated by such
assignment.

14. INDEMNITY IDX is the owner of the Software, or has adequate rights to
license to Customer the use of the Software as herein provided. IDX will, at its
expense, defend against and pay any final judgment against Customer arising out
of any claim that the Software infringes a U.S. copyright, a U.S. patent issued
as of the effective date of this Agreement, or a trade secret provided that (a)
Customer promptly notifies IDX in writing of such claim or action and (b) IDX
has sole control of the defense and settlement of such claim or action. In
defending against such claim or action, IDX may at its option (i) consent, (ii)
settle, (iii) procure for Customer the right to continue using the Software, or
(iv) modify or replace the Software so that it no longer infringes, to the
extent that the exercise of any such option does not result in a material
adverse change in the operational characteristics of the Software, and
equivalent functions and performance provided by the Software remain following
implementation of such option. If IDX concludes in its judgment that none of the
foregoing options is reasonable, then IDX will refund or credit to Customer the
license fee paid by Customer under this Agreement, less a pro rata credit for
each full or partial month of the first one hundred and twenty (120) months
following the effective date of this Agreement, Customer will return the
original and all whole or partial copies of the Software to IDX, and the license
granted hereunder will terminate. IDX has no liability with respect to patent
infringement or trade secret misappropriation arising out of modifications of
the Software made to Customer's order or specification or use of the Software in
combination with other software or equipment not specified on a schedule or
attachment hereto. This paragraph states the entire obligation of IDX regarding
infringement of intellectual property rights, and will survive the termination
of this Agreement.

15. IDX SHALL NOT BE LIABLE TO CUSTOMER UNDER ANY CIRCUMSTANCES FOR ANY
CONSEQUENTIAL, SPECIAL, INCIDENTAL, PUNITIVE OR INDIRECT DAMAGES (INCLUDING
WITHOUT LIMITATION LOSS OF PROFIT, REVENUE, BUSINESS OPPORTUNITY OR BUSINESS
ADVANTAGE), WHETHER BASED UPON A CLAIM OR ACTION OF TORT CONTRACT, WARRANTY,
NEGLIGENCE, STRICT LIABILITY, BREACH OF STATUTORY DUTY, CONTRIBUTION, INDEMNITY
OR ANY OTHER LEGAL THEORY OR CAUSE OF ACTION, EVEN IF ADVISED OF THE POSSIBILITY
OF SUCH DAMAGES.

16. TERMINATION This Agreement shall terminate at the option of either party
upon the failure of the other party to perform or observe any material covenant
or obligation set forth in this Agreement, provided the non-performing party has
been given written notice and ninety (90) days opportunity to cure such failure.
Upon any termination of this Agreement, Customer shall cease using the Software
and shall return to IDX, or at IDX's option destroy, the original and all copies
of the Software, the Documentation and any other materials provided by IDX. The
obligations of Customer set forth in the paragraphs entitled "Scope" and "Title
and Ownership" shall continue in full force and effect upon any termination of
this Agreement.

17. DISPUTES At the option of either party, any dispute as to the performance of
a party's obligations under this Agreement or any related matter shall be
referred to non-binding mediation by a neutral third party, the costs of whom
shall be paid jointly by IDX and the Customer. Each party shall cooperate in
such mediation but may terminate mediation at any time after the expiration of
sixty (60) days from commencement thereof. Nothing herein shall preclude either
party from exercising any and all legal rights available to it in a court of
competent jurisdiction, and nothing contained in this paragraph shall prevent or
preclude resort to mediation or other dispute resolution while litigation is
pending. No offer, finding, action, inaction or recommendation made or taken in
or as a result of mediation shall be considered for any purpose an admission of
a party, nor shall it be offered or entered into evidence in any legal
proceeding.

18. NOTWITHSTANDING ANYTHING TO THE CONTRARY, IDX'S AGGREGATE MONETARY LIABILITY
FOR ANY CAUSE OR CAUSES (REGARDLESS OF THE FORM OF ACTION) UNDER OR RELATING TO
THIS AGREEMENT, THE HARDWARE OR THE SOFTWARE, SHALL IN NO EVENT EXCEED THE TOTAL
OF ALL AMOUNTS PAID TO IDX BY CUSTOMER FOR SOFTWARE LICENSE FEES PURSUANT TO
THIS AGREEMENT, LESS A PRO RATA ABATEMENT OF SUCH FEES FOR EACH FULL OR PARTIAL
MONTH OF THE FIRST ONE HUNDRED TWENTY (120) MONTHS FOLLOWING THE EFFECTIVE DATE
OF THIS AGREEMENT UNTIL THE INSTITUTION OF LITIGATION.

19. INTERPRETATION This Agreement is not intended nor shall it be interpreted,
to confer any benefit, right or privilege in any person or entity not a party
hereto. Unless specified to the contrary in any schedule, supplement or other
attachment, in the event of any conflict or inconsistency between such items and
the provisions of this Agreement, the provisions of this Agreement shall prevail
and govern the interpretation thereof. In the event any provision hereof shall
be deemed invalid or


<PAGE>


unenforceable by any court or governmental agency, such provision shall be
deemed severed from this Agreement and replaced by a valid provision which
approximates as closely as possible the intent of the parties. All remaining
provisions shall be given full force and effect. This Agreement has been
mutually negotiated, and therefore shall be deemed to have been negotiated and
prepared at the joint request, direction and construction of the parties, at
arms length, and shall be interpreted in accordance with its terms without favor
to either party. This Agreement shall become effective and shall be binding only
upon acceptance by IDX at its offices in Burlington, Vermont. This Agreement
shall be governed by, subject to, and interpreted in accordance with, the laws
of the State of Vermont. Any cause or action against IDX arising out of or in
connection with this Agreement or any schedule or other agreement executed in
connection herewith shall be instituted and served upon IDX not later than two
(2) years following the effective date of this Agreement.

20. MISCELLANEOUS Any notice or communication provided or permitted hereunder
shall expressly describe its purpose and scope, and shall be in writing and
shall be deemed duly given or made if delivered in person or if sent by U.S.
registered mail, return receipt requested, postage prepaid, addressed to the
attention of the chief executive officer of the party for which it is intended
at the address set forth in this Agreement or at any other address specified by
a party in writing. Except as expressly provided to the contrary in this
Agreement, the dates and times by which Customer or IDX is required to render
delivery or performance under this Agreement shall be automatically postponed to
the extent, and for the period of time, that Customer or IDX, as the case may
be, is prevented from meeting such dates and times by reason of causes beyond
its reasonable control. The foregoing shall not excuse any failure to make
payment of any amount due hereunder that has continued for more than ninety (90)
days.

21. THIS AGREEMENT AND THE SCHEDULES AND OTHER AGREEMENTS INDICATED AS INCLUDED
ON THE FIRST PAGE HEREOF CONTAIN THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN
IDX AND CUSTOMER WITH RESPECT TO THE SELECTION, PROCUREMENT AND IMPLEMENTATION
OF THE HARDWARE AND THE SOFTWARE AND THEIR PERFORMANCE IN EVERY NATURE AND
RESPECT, AND AS SUCH THIS AGREEMENT SUPERSEDES ALL PRIOR AND CONTEMPORANEOUS
AGREEMENTS, NEGOTIATIONS, REPRESENTATIONS, AND PROPOSALS, WRITTEN AND ORAL,
RELATING TO THE HARDWARE AND SOFTWARE. NO CONTRARY TERMS AND CONDITIONS OF ANY
SUBSEQUENT CUSTOMER PURCHASE ORDER, NO COURSE OF DEALING, TRADE CUSTOM OR USAGE
OF TRADE, AND NO WARRANTY OR PROMISE MADE DURING THE COURSE OF PERFORMANCE, WILL
VARY OR CONTRADICT THE TERMS OF THIS AGREEMENT, UNLESS EXPRESSLY AGREED TO IN
WRITING. CUSTOMER EXPRESSLY ACKNOWLEDGES, AGREES AND REPRESENTS TO IDX THAT
THERE ARE NO UNDERSTANDINGS OR AGREEMENTS WITH RESPECT TO THE HARDWARE OR
SOFTWARE OTHER THAN AS EXPRESSLY SET FORTH IN THIS AGREEMENT.

                                             a New York limited liability 
                                             partnership (the "Medical Group"), 
                                             and UPTOWN PHYSICIAN MANAGEMENT, 
                                             INC., a Delaware corporation (the 
                                             "Management Company").

     The Medical Group is a limited liability partnership involved in providing
a range of medical services including primary care and specialty medical
services (the "Medical Services") to the general public. The Management Company
is a corporation engaged in the business of providing administrative, financial,
marketing, information technology and operational services to professional
medical organizations. The Management Company and the Medical Group desire to
enter into this Agreement, pursuant to which, among other things, the Management
Company will render services to the Medical Group.

     ACCORDINGLY, the Medical Group and the Management Company agree as follows:

     SECTION 1. Retention of the Management Company. (a) The Medical Group
hereby retains the Management Company to provide the management and
administrative services (the "Management Services") described on Schedule I, and
the Management Company accepts such retention, upon the terms and subject to the
conditions set forth herein.

     (b) During the Term (as defined below) of this Agreement, the Management
Company shall be the exclusive provider of the Management Services utilized by
the Medical Group. Notwithstanding anything contained herein to the contrary,
(i) the Management Company and the Medical Group intend to act and perform with
respect to each other as independent contractors, and the provisions hereof are
not intended to create any partnership, joint venture, agency or employment
relationship between the parties and (ii) the Management Company is hereby
engaged solely to provide the Management Services to the Medical Group and shall
not interfere with, control, direct or supervise the Medical Group or any
licensed medical professional employed thereby in connection with the provision
of the Medical Services.

     (c) The parties agree that the benefits to the Medical Group hereunder do
not require, are not payment for and are not in any way contingent upon the
admission, referral or any other arrangement for the provision of any item or
service offered by the Management Company to any of the Medical Group's patients
in any medical facility or laboratory controlled, managed or operated by the
Management Company or to any other medical practice to which the Management
Company or its affiliates provides management services.

     (d) The Medical Group hereby designates and appoints the Management Company
to be the agent of the Medical Group during the Term to perform the following
duties and for those purposes incidental thereto: (i) to bill patients and third
party payors in the Medical Group's name and on its behalf; (ii) to collect
accounts receivable resulting from such billing and deposit such amounts in the
Operating Account (as defined in Schedule I); (iii) to receive payments and
prepayments from the Medical Group's patients, Blue Cross and Blue Shield
organizations, insurance companies, health care plans, Medicare, Medicaid, HMO's
and any and all other third party payors and deposit such amounts in the

money orders, insurance payments, cash, cash equivalents and other instruments
received in payment of accounts receivable and deposit such amounts in the

expressly set forth in Sections 1(d)(i) through (v) above. From time to time at
the Management Company's request, the Medical Group shall make available to the

Medical Group to sign any letters, checks, instruments or other documents (the
"Documents") on behalf of the Medical Group that are necessary for the
Management Group to perform its duties as agent under this Section 1(d) and the
Management Services. If the Management Company notifies the Medical Group that
the Authorized Officer is not signing the Documents in a timely manner, the

the Renegotiated Percentage and shall issue a written determination setting

(the "Hardware, Software and Maintenance Fee"). The Management Company shall use
every reasonable effort to provide the hardware for the Med-E-Practice system at

Medical Group shall be adjusted, if necessary, to reflect the most favored
customer rates of ACN and its affiliates.

     (f) The Medical Group shall pay its obligations to the Management Company
in a prompt and timely manner.


     SECTION 7. Certain Covenants. (a) Except for the physician practices and

such Medical Practice without any restriction other than the restrictions set

                                       -7-
<PAGE>

incurred by reason of the Medical Group or any affiliate thereof being named as

Personnel, other employees, consultants, representatives or agents (the "Medical
Group Disclosees") nor the Management Company, its employees, consultants,
representatives or agents (the "Management Company Disclosees") shall, at any
time after the execution and delivery hereof, directly or indirectly disclose
any confidential or proprietary information relating to the other party hereto
to any person, firm, corporation, association or other entity, nor shall the
Medical Group Disclosees or the Management Group Disclosees make use of any of
such confidential or proprietary information for its or their own purposes or
for the benefit of any person, firm, corporation or other entity except the
other party hereto or any subsidiary or affiliate thereof. The foregoing
obligation shall not apply to any information which the Medical Group Disclosees
or the Management Company Disclosees, as the case may be, can establish to have
(i) become publicly known without breach of this Agreement by it or them or (ii)
to have been given to the Medical Group by a third party who is not obligated to
maintain the confidentiality of such information.

     (b) The term "confidential or proprietary information" shall mean all
information which is known to the Medical Group Disclosees or the Management
Company Disclosees, as the case may be, which relates to this Agreement or
matters such as patient medical records and charts, trade secrets, books and
records, supplies, pricing and cost information, marketing plans, strategies and
forecasts. Nothing contained herein shall prevent the Medical Group Disclosees
or the Management Company Disclosees, as the case may be, from furnishing
confidential or proprietary information pursuant to a direct order of a court of
competent jurisdiction.

     SECTION 12. Restrictive Covenants. The parties recognize that the
Management Services shall be deliverable only if the Medical Group operates an
active medical practice to which the Medical Personnel associated with the
Medical Group devote substantial time and attention. To that end:

     (a) During the Term, neither the Medical Group, nor the Physician Partners
or Physician Employees, so long as they continue to be Physician Partners and
Physician Employees, shall provide Medical Services at any medical office,
clinic or other health care facility other than a Facility, without the prior
written approval of the JMAB; provided, however, that a Physician Partner or
Physician Employee may provide Medical Services at a health care facility other
than a Facility, if, and only if, the physician revenues relating to such
Medical Services are included in the Medical Group's revenues for the purpose of
calculating the Management Company's fees pursuant to Section 6. The Medical
Group shall cause the Physicians to comply with their obligation pursuant to
this Section 12(a).

     (b) The Medical Group acknowledges and recognizes the highly competitive
nature of the business of the Management 


                                       -11-
<PAGE>

Company and that goodwill is an essential asset of the Management Company.
Accordingly, during the Term, the Medical Group shall not (i) directly or
indirectly engage in any Competitive Business (as defined below), whether such
engagement shall be as an employer, owner, consultant, partner or other
participant in any Competitive Business, (ii) assist others in engaging in any
Competitive Business in the manner described in the foregoing clause (i), (iii)
employ or otherwise induce employees of the Management Company to terminate
their employment with the Management Company or engage in any Competitive
Business or (iv) induce customers or vendors of the Management Company to alter
or terminate their business relationship with the Management Company. As used
herein, the term "Competitive Business" shall mean any business which, directly
or indirectly, competes with the Management Company in the provision of
management services which are substantially equivalent to the Management
Services provided by the Management Company.

     (c) The Management Company and the Medical Group acknowledge and agree that
since a remedy at law for any breach or attempted breach of the provisions of
this Section 12 shall be inadequate the non-breaching party shall be entitled to
specific performance and injunctive or other equitable relief in case of any
such breach or attempted breach, in addition to any remedies available at law.
If any provision of this Section 12 relating to the restrictive period and/or
the scope of activity restricted shall be declared by a court of competent
jurisdiction to exceed the maximum time period or scope of activity restricted
such court deems reasonable and enforceable under Applicable Law, the time
period and/or scope of activity restricted held to be reasonable and enforceable
by such court shall thereafter be the restrictive period and/or scope of
activity restricted applicable to the restrictive covenant provisions in this
Section 12. The invalidity or non-enforceability of this Section 12 in any
respect shall not affect the validity or enforceability of the remainder of this
Section 12 or of any other provisions of this Agreement.

     SECTION 13. Activities of the Management Company. (a) The Medical Group and
the Management Company acknowledge that certain federal and state statutes
severely restrict or prohibit the Management Company from providing medical
services. Accordingly, during the Term, the Management Company represents and
warrants that it shall not provide or otherwise engage in services or activities
which constitute the practice of medicine, as defined in Applicable Law, except
in compliance therewith.

     (b) The Management Company shall not interfere with the exercise of
professional judgment by any Medical Personnel nor shall the Management Company
interfere with, control, direct or supervise any health care provider in
connection with the provision of Medical Services. The foregoing sentence shall
not preclude the Management Company from assisting the Medical Group in the
development of professional protocols 


                                      -12-
<PAGE>

and monitoring compliance with policies and procedures that have been instituted
in accordance with this Agreement.

     SECTION 14. Assignment. Except with respect to the Services Agreement dated

Company nor the Medical Group shall assign or delegate its rights or duties

corporation to purchase, operate or own equity interests in medical practices or
professional corporations, and if the Medical Group or any holder or a
partnership interest in the Medical Group (the "Offeror") proposes to sell,
transfer, assign, pledge, distribute, encumber or otherwise dispose of, either
voluntarily or involuntarily, with or without consideration, any partnership
interest of the Medical Group or all or substantially all of the assets of the
Medical Group (a "Transfer") to any third party (the "Third Party"), then the
Offeror shall, before such Transfer, deliver to the Management Company an offer
(the "Offer") to enter into such Transfer in place of the Third Party upon the
terms offered to such Third Party. The Offer shall remain open and irrevocable
for a period of 45 days from the date of its delivery during which time the
Management Company shall 


                                      -15-

such Offer within the 45 day period and the Offeror proposes to enter into such
Transfer with a Third Party upon terms more favorable than the Offer (the "New
Offer"), the Management Company shall have the right to accept any New Offer
within a 30 day period following the Offeror's delivery to the Management
Company of a written notice containing the terms of such New Offer.

                                       corporation (the "Management
                                       Company").

     The PC is a professional medical corporation involved in providing
cardiothoracic surgery and invasive cardiology medical services to the general
public. The Management Company will be engaged in the business of providing
non-medical administrative, financial, marketing, information technology and
operational services to professional medical corporations (the "Business"). The
Management Company, the PC and the Physicians desire to enter into this
Agreement, pursuant to which, among other things, the Management Company will
render certain non-medical management services to the PC.

     ACCORDINGLY, the PC, the Physicians and the Management Company agree as
follows:

terms and subject to the conditions set forth herein.

     (b) During the term of this Agreement, the Management Company shall be the
exclusive provider of all non-medical management services utilized by the PC.
Notwithstanding anything contained herein to the contrary, (i) the Management

provisions hereof are not intended to create any partnership, joint venture,
agency or employment relationship between the parties and (ii) the Management
Company is hereby engaged solely to provide non-medical management services to
the PC and shall not interfere with, control, direct or supervise the PC or any
medical professional employed thereby in connection with the provision of
professional medical services.

     (c) The parties agree that the benefits to the PC hereunder do not require,
are not payment for and are not in any way contingent upon the admission,
referral or any other arrangement for the provision of any item or service
offered by the Management Company to any of the PC's patients in any medical


                                      -1-

Company.

and lawful attorney and agent to sign in the PC's name and on its behalf any and
all agreements, instruments, certificates, proxies or other documents which are
necessary or advisable in connection with the performance by the Management
Company of its Management Services hereunder for a period of one year from the
date hereof; provided, however, that such appointment shall be automatically
extended for additional periods of one year each, unless the PC delivers to the
Management Company, not less than 60 nor more than 90 days prior to the
expiration of any one year period, written notice of the PC's intention to
revoke such appointment. In the event that such appointment is terminated for
any reason, the PC shall execute in a timely manner any and all documents that
the Management Company may reasonably request it to execute.

     SECTION 2. Term. (a) Subject to Section 30, this Agreement shall commence
on August 21, 1995 (the "Effective Date") and shall expire on the twentieth
anniversary of the Effective Date unless terminated earlier pursuant to the
terms hereof (the "Base Term").

     (b) Unless terminated earlier as provided for herein, the Base Term of this
Agreement shall be automatically extended for additional terms ("Additional
Terms" and together with the Base Term, the "Term") of five years each, unless
either party delivers to the other party, not less than 12 months nor more than
15 months prior to the expiration of the then-current term, written notice of
such party's intention not to extend the Term of this Agreement.

     SECTION 3. Management Services. (a) The Management Company shall be the
sole and exclusive manager and administrator of all day-to-day business
functions for the PC. The Management Company shall have no authority, directly
or indirectly, to perform, and shall not perform, any medical function. The
Management Company may, however, advise the PC as to the relationship between
its performance of medical activities and the administrative and business
functioning of its practice.

     (b) During the Term, the Management Company or its designee, which designee
shall be reasonably consented to by the PC in a timely manner, shall (i)

remain a member of the Joint Management Advisory Board for as long as such
Former Chief so desires and shall have the right (i) to cast two or fewer votes
during such period and/or (ii) to assign one or two of his votes to the new
chief physician (such new chief physician or any successor thereto, the "New
Chief") of such division at LHH if such New Chief is or has become a member of
the PC. If the New Chief is or becomes a member of the PC, the New Chief shall
become a member of the Joint Management Advisory Board and may cast those votes,
if any, assigned to the New Chief by the Former Chief. Upon the retirement of
the Former Chief from the Joint Management Advisory Board, the New Chief shall
have the right to cast two votes. A quorum of the Joint Management Advisory
Board for voting purposes shall consist of three members and the act of a
majority of the total votes available to all members of the Joint Management
Advisory Board shall be the act of the Joint Management Advisory Board. Any
written action taken by the Joint Management Advisory 


                                      -6-

Board in lieu of a meeting shall require the unanimous approval of all members

          iii) Patient Fees; Collection Policies; Accounts Payable Policies. As
     part of the Budget, in consultation with the Management Company and the PC,

facts and circumstances.

     (b) The PC shall use and occupy any Facility (as defined below) exclusively

retaining of professional liability insurance by (i) ensuring that its Physician
Employees are insurable or (ii) instituting proceedings to terminate within 90
days any Physician Employee who is not insurable or who loses his insurance

in the insurance status of any Physician Employee within two days of the PC
receiving notice of such change. The PC shall require all Physician Employees to
participate in an on-going risk management program.

perform any of the services required herein in the event of strikes, lock-outs,

the counties of Bergen, Hudson, Middlesex, Union or Essex in the State of New
Jersey or the county of Fairfield in the State of Connecticut without the

Management Company to obtain such Physician's consent shall be automatically
terminated.

     (b) The Management Company shall offer the services of the PC to any

     SECTION 7. Restrictive Covenants and Liquidated Damages. The parties
recognize that the services to be provided by the Management Company shall be
deliverable only if the PC operates an active medical practice to which the
physicians associated with the PC devote substantial time and attention. To that
end:

     (a) During the Term, neither the PC, nor the Physicians shall establish,

remedies available at law. If any provision of this Section 7 relating to the
restrictive period and/or the scope of activity restricted shall be declared by
a court of competent jurisdiction to exceed the maximum time period or scope of
activity restricted such court deems reasonable and enforceable under applicable
law, the time period and/or scope of activity restricted held to be reasonable
and enforceable by such court shall thereafter be the restrictive period and/or
scope of activity restricted applicable to the restrictive covenant provisions
in this Section 7. The invalidity or non-enforceability of this Section 7 in any
respect shall not affect the validity or enforceability of the remainder of this
Section 7 or of any other provisions of this Agreement.

that, in the case of clause (A) or clause (B) above, if the value of all the
shares of AHC stock transferred hereunder plus the value received from the prior
                                          ----

any reason for a period of 90 consecutive days. The PC shall provide written
notice to the Management Company of the addition or subtraction of any
practicing physician within five business days of such addition or subtraction
occurring.

                                                --------  -------
Management Company reserves the right to purchase accounts receivable (i) not
being paid by funds from the Medicare or Medicaid programs or (ii) in the event
any state or federal laws or regulations, now existing or enacted or promulgated
after the Effective Date, are interpreted by judicial decision, a regulatory
agency or legal counsel of the Management Company in such a manner as to allow
the discounted purchase of Medicare or Medicaid receivables, all accounts
receivable, at a discounted rate to be mutually agreed upon by the parties based
upon the historical accounts receivable collection rates of the PC, Lenox Hill
Cardiothoracic Surgical, P.C. ("LHCS PC") and Lenox Hill Interventional

other readily available funds, in equal, interest-free weekly installments

the thirteenth week in each fiscal quarter. The Management Company shall have
the right to deduct, withhold and set-off from any Receivable Payment owed to
the PC an amount equal to the amount owed to the Management Company by the PC on
the Signing Fee.

               (e)  Although it is the intention of the parties that the
Management Company purchase and thereby become owner of the accounts receivable
of the PC, in cash such purchase shall be ineffective for any reason, the
Management Company shall make a loan to the PC in an amount equal to the
Receivable Payment which loan shall be secured by a Security Agreement in the
form attached as Exhibit E which the PC is entering into concurrently herewith.
                 ---------

shall prepay principal of such loan in an amount equal to its collections of
accounts receivable on each day such collections are made prior to the due date
of such loan. In addition, the PC shall cooperate with the Management Company
and execute all necessary documents in connection with the pledge of such
accounts receivable to the Management Company or at the Management Company's
option, its lenders. All collections, including, without limitation, all
collections of Medicare and Medicaid payments, in respect of such accounts
receivable shall be made by the Management Company on behalf of the PC. To the
extent that the PC gains possession of any payments in respect of such accounts
receivable, the PC shall direct such payments to the Management Company for
deposit in a bank account designated by the Management Company. Any accounts
receivable purchased by the Management Company and not collected within
90 days of such purchase shall be repurchased by the PC at the Management
Company's costs thereof.

     8. Termination Without Cause. If the PC shall terminate the employment of

     (b) Upon the termination of the Employee's employment hereunder pursuant to
an Involuntary Termination, neither the Employee nor his or her beneficiary or
estate shall have any further rights or claims against the PC under this
Agreement except to receive a termination payment equal to that provided for in
Section 10(a) hereof, plus an amount equal to the pro rata share of the
Employee's cash bonus, if any, that would have been earned pursuant to Section
5(b) based upon an annualized calculation of the Employee's performance through
the date of termination.

     (c) Upon the termination of the Employee's employment hereunder pursuant to
a Termination Without Cause, neither the Employee nor his or her beneficiary or
estate shall have any further rights or claims against the PC under this
Agreement except to receive a termination payment equal to the amount provided
for in Section 10(a) hereof, plus an amount equal to the pro rata share of the
Employee's cash bonus, if any, that would have been earned pursuant to Section

<PAGE>

physician, consultant, partner or other participant in any Competitive Business,

described in the foregoing clause (i), (iii) induce employees of the PC to
terminate their employment with the PC or engage in any Competitive Business or
(iv) induce patients of the PC to alter or terminate their business or medical

Island, the counties of Westchester, Rockland, Nassau or Suffolk in the State of
New York, the counties of Bergen, Hudson, Middlesex, Union or Essex in the State
of New Jersey or the county of Fairfield in the State of Connecticut.

     (b) The Employee understands that the foregoing restrictions may limit his
or her ability to earn a livelihood in a Competitive Business, but the Employee
nevertheless believes that he or she has received and will receive sufficient
consideration and other benefits in connection with his or her employment to
clearly justify such restrictions which, in any event, the Employee does not
believe would prevent him or her from earning a living. Nothing herein contained
shall prohibit the Employee from engaging in a business or medical practice that
is not a Competitive Business.

     (c) During and after the Employment Period, the Employee will preserve and
protect the confidentiality of the Confidential Information (as defined below)
and shall not use or disclose to any person, firm, corporation, medical practice
or other business entity, except as required by law or judicial process, any
Confidential Information for any reason or purpose whatsoever, nor shall he or
she make use of any of the Confidential Information for his or her own purposes
or for the benefit of any person, firm, corporation, medical practice or other
business entity except the PC. "Confidential Information" means any information
of a confidential or proprietary nature, including trade secrets, technical
data, know-how and financial, administrative, marketing and other business
information which the Employee produces or otherwise obtains during the course
of his or her employment with respect to any activity in which the PC is or has
been engaged, or which is entrusted to the PC by others. The foregoing
obligation shall not apply to any information which the Employee can establish
to have (i) become publicly known without breach of this Agreement by him or her
or (ii) to have been given to the Employee by a third party who is not obligated
to maintain the confidentiality of such information. At the time of termination
of the Employee's employment with the PC, the Employee will surrender to the PC
all documents, software and other tangible items in whatever form in his or her
possession or under his or her control which contain any Confidential
Information that belong to or have been entrusted to the Employee by the PC.

assign to the PC for its sole use and benefit any and all inventions,
improvements, technical information, methods and suggestions relating in any way
to the business or medical practice of the PC, which he or she may develop or
acquire during the Employment Period (whether or not during usual working
hours), together with all patent applications, patents, copyrights and reissues
thereof that may at any time be granted for or upon any such invention,
improvement, technical information or method. In connection therewith:

          (a) The Employee shall without charge, but at the expense of the PC,
     promptly at all times hereafter execute and deliver such applications,
     assignments, descriptions and other instruments as may be reasonably
     necessary or proper in the reasonable opinion of the PC to vest title to
     any such inventions, improvements, technical information, methods, patent
     applications, patents, copyright applications, copyrights or reissues of
     any thereof in the PC and to enable it to obtain and maintain the entire
     right and title thereto throughout the world; and

          (b) The Employee shall render to the PC at its expense (including a
     reasonable payment for the time involved in case he or she is not then in
     its employ) all such assistance as it may reasonably require in the
     prosecution of applications for said patents, copyrights or reissues
     thereof, in the prosecution or defense or interferences which may be
     declared involving any said applications, patents or copyrights and in any
     litigation in which the PC may be involved relating to any such patents,
     copyrights, inventions, improvements, technical information or methods.

     13. Enforcement. It is the desire and intent of the parties hereto that the
provisions of this Agreement shall be enforced to the fullest extent permissible
under the laws and public policies applied by the jurisdiction whose laws govern
this Agreement. Accordingly, to the extent that a restriction contained in this
Agreement is more restrictive than permitted by the laws of any jurisdiction
where this Agreement may be subject to review and interpretation, the terms of
such restriction, for the purpose only of the operation of such restriction in
such jurisdiction, shall be the maximum restriction allowed by the laws of such
jurisdiction and such restriction shall be deemed to have been revised
accordingly herein.

     14. Remedies; Survival. (a) The Employee acknowl- edges and understands
that the provisions of this Agreement are of a special and unique nature, the
loss of which cannot be accurately compensated for in damages by an action at
law, and that the breach of the provisions of this Agreement would cause the PC
irreparable harm. In the event of a breach by the Employee of the provisions of
Section 11 or 12 hereof, the PC shall be entitled to an injunction restraining
him from such


                                       5
<PAGE>

breach. Nothing herein contained shall be construed as prohibiting the PC from
pursuing any other remedies available for any breach of this Agreement.

     (b) Notwithstanding anything contained in this Agree- ment to the contrary,
the provisions of Sections 11, 12, 13 and this Section 14, shall survive the
expiration or other termination of this Agreement until, by their terms, such
provisions are no longer operative.

     (c) It is understood and agreed that the provisions of this Agreement are
separate and distinct from any other agreement among the parties hereto.
Accordingly, in the event of a breach of the provisions hereof, the breaching
party shall only be held responsible for damages arising under this Agreement
and not for any damages which may be claimed to arise under or with respect to
any other agreement that is not separately breached.

     15. Notices. Notices and other communications hereun- der shall be in
writing and shall be delivered personally or sent by air courier or first class

would still be payable to him or her hereunder if he or she had continued to

Employee in a writing delivered to the PC, or if there be no such designated
beneficiary, to his or her estate.

     17. Governing Law. This Agreement shall be governed by, and construed and
enforced in accordance with, the laws of the State of New York.

     18. Waiver of Breach. The waiver by either party of a breach of any

interpretation of this Agreement.

     21. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     22. Assignment. With respect to the Employee, this Agreement is personal in
its nature and the Employee shall not assign or transfer this Agreement or any
rights or obligations hereunder. The PC may in its sole discretion assign or
otherwise transfer this Agreement and the provisions hereof (including, without
limitation, Sections 11, 12 and 13) shall inure to the benefit of, and be
binding upon, each successor of the PC, whether by merger, consolidation,
transfer of all or substantially all assets, or otherwise.

     23. Counterparts. This Agreement may be executed in any number of
counterparts, and each such counterpart hereof shall be deemed to be an original
instrument, but all such counterparts together shall constitute but one
agreement.

                            [FORM OF PROMISSORY NOTE]

                                                             ____________, 199_

     FOR VALUE RECEIVED, the undersigned, ADVANCED HEART INSTITUTE OF NEW YORK,
P.C., a New York professional corporation (the "Borrower"), hereby promises to
pay to the order of Majean Sub 2, Inc., a Delaware corporation (the "Lender"),
on the [insert date that is the 36-month anniversary of the Effective Date] the
principal sum of ________________________ Dollars ($___________)in lawful money
of the United States of America in immediately available funds, and to pay
interest from the date hereof on the principal amount hereof from time to time
outstanding, in like funds, at the prime rate as quoted by Citibank, N.A. on the
date hereof, which interest shall be paid in full on a monthly basis.

     The Borrower may at any time, and from time to time, pre-pay this Note, in
whole or in part, without premium or penalty. All prepayments hereunder shall be
applied first to accrued interest, with the balance applied to principal.

     In addition to paying this Note as provided herein, the Borrower may pay
this Note as provided in Section 8(b) of the Management Services Agreement dated
as of August 7, 1995, among Advanced Heart Institute of New York, P.C.,
Valavanur A. Subramanian, M.D., Jeffrey Moses, M.D. and Majean Sub 2, Inc.

     If any payment of principal of or interest on this Note shall become due on
a Saturday, Sunday or a public holiday under the laws of either the State of New
York or the United States of America, then such payment shall be made on the
next succeeding business day.

     The Borrower hereby waives diligence, presentment, demand, protest and
notice of any kind whatsoever. The failure by the Lender to exercise any of its
rights under this Note in any particular instance shall not constitute a waiver
thereof in that or any subsequent instance.

     All borrowings evidenced by this Note and all payments and prepayments of
the principal hereof and interest hereon and the respective dates and maturity
dates thereof shall be noted on the grid attached hereto, and each such notation
shall be conclusive absent manifest error; provided, however, that the failure
of the Lender to make such a notation, or any error herein, shall not affect the
obligations of the Borrower to 

<PAGE>

repay, in accordance with the terms of this Note and the Letter Agreement, the
principal amount of this Note.

     If any of the following shall occur and be continuing (each, an "Event of
Default"):

          (a) the Borrower shall fail to pay when due any principal of or
     interest on this Note and such default shall continue for a period of five
     (5) business days after the Borrower shall have received written notice of
     such default from the Lender; or

          (b) the Borrower shall be declared a bankrupt or shall become
     protected from actions by its creditors;

then the Lender may, at its option, exercise any or all rights, powers and
remedies afforded under law, and shall have the right to declare the unpaid
balance of principal of and accrued interest on this Note immediately due and
payable.

     This Note shall be governed by and construed in accordance with the laws of
the State of New York (without giving effect to principles or conflicts of
laws).

                                                to Management Services Agreement

             [FORM OF SECURITY AGREEMENT (PC's Accounts Receivable)]

                                             SECURITY AGREEMENT dated as of 
                                        _____ __, 1995, between MAJEAN SUB
                                        2, INC., a Delaware corporation 
                                        (the "Management Company"), and
                                        ADVANCED HEART INSTITUTE OF NEW
                                        YORK, P.C., a New York professional
                                        corporation (the "PC").

     Reference is made to the Management Services Agreement dated as of August
7, 1995 among the PC, Valavanur A. Subramanian, M.D., Jeffrey Moses, M.D., and
the Management Company (the "Management Services Agreement")

     In order to secure the PC's obligations to the Management Company, the PC
has agreed to grant to the Management Company a security interest in all of the
PC's accounts receivable, by entering into this Agreement with the Management
Company.

     ACCORDINGLY, in consideration of the premises and the mutual covenants and
agreements contained in this Agreement, and for other good and valuable
consideration the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

     SECTION 1. Definitions. (c) As used in this Agree- ment, the following
terms shall have the following meanings:

     "Collateral" means all of the PC's accounts receivable, irrespective of the
form thereof, whether now owned or existing or hereafter acquired or arising and
regardless of where located.

     "Event of Default" means any default by the PC in the payment or
performance of any Obligation and the continuance of such default for a period
of five days after notice thereof from the Management Company.

     "Obligations" means any and all obligations and liabilities of the PC to
the Management Company arising out of Section 9(d) of the Management Services
Agreement.

     "UCC" means the Uniform Commercial Code as in effect on the date hereof in
the State of New York; provided, however, that if by reason of mandatory
provisions of law, the perfection or the effect of perfection or non-perfection
of the Security Interest in any Collateral is governed by the Uniform 

<PAGE>

Commercial Code as in effect in a jurisdiction other than New York, "UCC" means
the Uniform Commercial Code as in effect in such other jurisdiction for purposes
of the provisions hereof relating to such perfection or effect of perfection or
non-perfection.

     (d) Unless otherwise defined herein, or unless the context otherwise
requires, all terms used herein which are defined in the UCC shall have the
meanings ascribed to them in the UCC.

     (e) Capitalized terms used and not defined in this Agreement have the
meanings ascribed to them in the Management Services Agreement.

     (f) The definitions in this Section 1 shall apply to the singular and
plural forms of the terms defined. Whenever the context requires, any pronoun
shall include the corresponding masculine, feminine and neuter forms. The words
"include," "in- cludes" and "including" shall be deemed to be followed by the
phrase "without limitation."

     (g) Unless otherwise specified, references in this Agreement to any Section
are references to such Section in this Agreement and references in any Section
or definition to any clause are references to such clause of such Section or
definition.

     SECTION 2. Grant of Security Interest. In order to continue to secure to
the Management Company the full and punctual payment (whether at stated
maturity, by acceleration or otherwise) and performance by the PC of all of its
Obligations, the PC hereby pledges, assigns, conveys, hypothecates and transfers
for security to the Management Company a continuing lien on and continuing first
priority security interest (the "Security Interest") in, all of PC's right,
title and interest in, to and under the Collateral. The Security Interest is
granted as security only and shall not subject the Management Company to, or
transfer or in any way affect or modify, any obligation or liability of the PC
with respect to any of the Collateral or any transaction arising in connection
therewith.

     SECTION 3. Rights and Remedies Upon Default. 

     (a) Generally. If an Event of Default shall have occurred and be
continuing, the Management Company may exercise all rights of a secured party
under the UCC, and, in addition, the Management Company shall have (i) all of
the rights and remedies provided for in this Agreement and (ii) all of the
rights and remedies to which a secured party is entitled under the laws in
effect in any jurisdiction where any rights and remedies hereunder may be
asserted, including, to the maximum extent permitted by law, the right to
exercise all voting, consensual and other powers of ownership pertaining to the
Collateral as if the Management Company were the sole 


                                       2
<PAGE>

and absolute owner thereof (and the PC agrees to take all such action as may be
appropriate to give effect to such right).

     (b) Sale of the Collateral. (i) If an Event of Default shall have occurred
and be continuing, the Management Company may, without being required to give
any notice (except as may otherwise be required by this Agreement or by
Applicable Law), sell the Collateral or any part thereof at public or private
sale, for cash, upon credit or for future delivery, and at such price or prices
as the Management Company may deem satisfactory. The Management Company may be
the purchaser of any or all of the Collateral so sold at any public sale, or, if
the Collateral is of a type customarily sold in a recognized market or is of a
type which is the subject of widely distributed standard price quotations, at
any private sale. The PC will execute and deliver such documents and take such
other action as the Management Company deems necessary or advisable in order
that any such sale may be made in compliance with law. Upon any such sale the
Management Company shall have the right to deliver, assign and transfer the
Collateral so sold to the purchaser thereof. Each purchaser at any such sale
shall hold the Collateral so sold to it absolutely and free from any Lien or
other claim or right of whatever kind, including any equity or right of
redemption of the PC which may be waived, and the PC, to the extent permitted by
law, hereby specifically waives all rights of redemption, stay or appraisal
which it has or may have under any law now existing or hereafter enacted or
adopted (as well as any rights to exoneration, subrogation or reimbursement
arising at law, in equity or otherwise).

     (ii) The Management Company shall give the PC not less than ten (10) days'
prior written notice of the time and place of any such sale or other intended
disposition of any of the Collateral, except any Collateral which threatens to
decline speedily in value or is of a type customarily sold on a recognized
market, and the PC agrees that such notice constitutes "reasonable notification"
within the meaning of, and for all purposes of, the applicable provisions of the
UCC. Any notice of such sale required by this Agreement shall, in case of a
public sale, state the time and place fixed for such sale, and in the case of a
private sale, state the day after which such sale may be consummated. Any such
public sale shall be held at such time or times within ordinary business hours
and at such place or places as the Management Company may fix in the notice of
such sale. At any such sale the Collateral may be sold in one lot as an entirety
or in separate parcels, as the Management Company may determine. The Management
Company shall not be obligated to make any such sale pursuant to any such
notice. The Management Company may, without notice or publication, adjourn any
public or private sale or cause the same to be adjourned from time to time by
announcement at the time and place fixed for the sale, and such sale may be made
at any time or place to which the same may be so adjourned. In the case of any
sale of all or any part of the Collateral on credit or for future delivery, the
Collateral so sold may be retained by the Management Company until the 


                                       3
<PAGE>

selling price is paid by the purchaser thereof, but the Management Company shall
not incur any liability in case of the failure of such purchaser to take up and
pay for the Collateral so sold and, in case of any such failure, such Collateral
may again be sold as permitted by and in accordance with this Agreement,
including the application of proceeds as set forth herein.

     (c) Other Rights. In addition to, and not in limitation of any rights or
remedies of the Management Company contained elsewhere in this Agreement, if an
Event of Default shall have occurred and be continuing, the Management Company
may require the PC to, and the PC agrees that it will, at its expense and upon
the request of the Management Company, forthwith assemble all or any part of the
Collateral as directed by the Management Company and make it available at a
place designated by the Management Company which is, in the Management Company's
opinion, reasonably convenient to the Management Company, whether at the
premises of the PC or otherwise.

     (d) General Authority. Effective only upon the occurrence and during the
continuance of an Event of Default, the PC hereby appoints the Management
Company its true and lawful attorney, with full power of substitution, in the
name of the PC or otherwise, for the sole use and benefit of the Management
Company, but at the expense of the PC, to exercise any power permitted by
Applicable Law with respect to any Collateral, which appointment is irrevocable
and coupled with an interest. Without limiting the generality of the foregoing,
the Management Company shall have the right (but not the obligation), upon the
occurrence and during the continuance of an Event of Default to:

          1. demand, sue for, collect, receive and give acquittance for any and
     all monies or property due or to become due on account or in exchange for
     any of the Collateral or by virtue of the Collateral;

          2. settle, compromise, compound, prosecute or defend any action or
     proceeding with respect to or other- wise affecting the Collateral;

          3. sell, transfer, assign or otherwise deal therein or therewith or
     the proceeds or avails of the Collateral, as fully and effectually as if
     the Management Company were the absolute owner thereof;

          4. extend the time of payment of any or all accounts or other
     obligations owed to the PC and to make any allowance and other adjustments
     with reference thereto;

          5. notify or direct the PC to notify any or all account debtors that
     the accounts have been assigned to the Management Company, for the ratable
     benefit of the Lenders, and that the Management Company has a security
     interest therein (the Management Company shall promptly 


                                       4
<PAGE>

     furnish the PC with a copy of any such notice, and the PC hereby agrees
     that any such notice, in the Management Company's sole discretion, may be
     sent on the PC's stationery);

          6. contact account debtors for any reason, including to direct or
     cause the PC to direct account debtors to make all payments due from them
     to the PC upon the accounts directly to or as directed by the Management
     Company;

          7. prior to the disposition of the Col- lateral, use, operate and
     control the Collateral to preserve the Collateral or its value, store or
     transfer the Collater- al without charge in or by means of any storage or
     transpor- tation facility owned or leased by the PC, or process, repair or
     recondition the Collateral or otherwise prepare it for disposition in any
     manner and to the extent the Management Company deems appropriate;

          8. use the information recorded on or contained in any data processing
     equipment and computer hardware and software relating to the accounts and
     other obligations owed to the PC to which the PC has access (subject to the
     proprietary rights applicable to such computer hardware and software) and
     do any other act or thing necessary, in the Management Company's sole
     discretion, to fulfill the PC's obligations to the Management Company under
     this Agreement or otherwise;

          9. make any payments and do any other acts which the Management
     Company deems desirable to protect the Security Interest in the Collateral,
     including paying, purchasing, contesting or compromising any Lien which, in
     the judgment of the Management Company, appears to be prior to or superior
     to the Security Interest, and to appear in and defend any action or
     proceeding purporting to affect the Security Interest and/or the value of
     the Collateral, and in exercising any such power or authority, to pay all
     reasonable expenses incurred in connection therewith, the PC's obligation
     with respect to the repayment thereof being secured under this Agreement;
     and

          10. receive, endorse and collect all checks made payable to the order
     of the PC representing any payment in respect of the Collateral or any part
     thereof and to give full discharge for the same.

     (e) Deficiency. If the proceeds of the sale, collection or other
realization of or upon all or part of the Collateral pursuant to the provisions
of this Agreement are insufficient to cover the costs and expenses of such
realization and the payment in full of the Obligations, the PC shall remain
liable for any deficiency.


                                       5
<PAGE>


     SECTION 4. Duration of Agreement; Release of Security. This Agreement and
the Security Interests shall terminate when all of the Obligations have been
fully and indefeasibly paid and performed or otherwise satisfied. The release of
Collateral or reassignment of rights to the PC upon the termination of this
Agreement shall be without recourse to or warranty by the Management Company and
shall be made by the Management Company at the expense of the PC. Upon the
release of Collateral or reassignment of rights to the PC, the Management
Company will, at the expense of the PC, execute and deliver to the PC such
documents as the PC shall reasonably request to evidence such release or
reassignment.

     SECTION 5. PC Remains Liable. Anything contained in this Agreement to the
contrary notwithstanding, (a) the PC shall remain solely liable to perform its
duties and obligations under the contracts and agreements included in the
Collateral to the extent set forth therein to the same extent as if this
Agreement had not been executed, (b) the exercise by the Management Company of
any of its rights and remedies hereunder shall not release the PC from any of
its duties or obligations under the contracts and agreements included in the
Collateral except to the extent the exercise of such rights renders the
performance of such duties or obligations by the PC impracticable under any such
agreement or contract, and (c) the Management Company shall not have any
obligation or liability under any contract or agreement included in the
Collateral by reason of this Agreement, and the Management Company shall not be
obligated in any manner to perform any of the obligations or duties of the PC
thereunder or to take any action to collect or enforce any claim for payment
assigned hereunder, except to the extent that the Management Company has
expressly and affirmatively assumed the rights and the obligations and duties of
the PC under any such contract or agreement.

     SECTION 6. Limitation on Duty of the Management Company Regarding the
Collateral. Beyond the exercise of reasonable care in the custody of the
Collateral, the Management Company shall have no duty as to any Collateral in
its possession or control or in the possession or control of any agent or
bailee, or any income thereon, or as to the preservation of rights against prior
parties or any other rights pertaining thereto. The Management Company shall be
deemed to have exercised reasonable care in the custody of the Collateral in the
Management Company's possession if the Collateral is accorded treatment
substantially equal to that which the Management Company accords its own
property or to that which the Management Company accords to the property of
others that the Management Company holds as a secured party. The Management
Company shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any warehouseman, carrier, forwarding agency, consignee or other
agent or bailee selected by the Management Company in good faith.


                                       6
<PAGE>


     SECTION 7. Security Interest Absolute. All rights of the Management Company
hereunder, the grant of the security interest in the Collateral and all
obligations of the PC hereun- der shall be absolute and unconditional
irrespective of (a) ex- cept to the extent not permitted to be waived under
Applicable Law, any lack of validity or enforceability of the Obligations, (b)
any change in the time, manner or place of payment of, or in any other term of,
all or any of the Obligations, or any other amendment or waiver of or any
consent to any departure from the PC Agreement or any other agreement or
instrument relating to any of the foregoing, (c) failure by the Management
Company to take steps to perfect or maintain perfected its security interest in,
or to preserve its rights to, any of the Collateral, (d) any exchange, release
or non-perfection of any other collateral, or any release or amendment or waiver
of or consent to or departure from any guaranty, for all or any of the
Obligations, (e) the disallowance under Section 502 of the Bankruptcy Code of
all or any portion of the claims of the Management Company for repayment of the
Obligations or (f) any other circumstance which might otherwise constitute a
legal or equitable defense available to, or a legal or equitable discharge of,
the PC with respect to the Obligations other than the indefeasible payment in
full of all of the Obligations.

     SECTION 8. No Waiver By the Management Company. No failure on the part of
the Management Company to exercise, and no delay in exercising and no course of
dealing with respect to, any right or power under this Agreement shall operate
as a waiver thereof, nor shall any single or partial exercise by the Management
Company of any right or power under this Agreement, or any abandonment or
discontinuance of steps to enforce such right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
of the Management Company in this Agreement are cumulative and are not exclusive
of any other rights or remedies available to the Management Company at law or in
equity. No notice to or demand on the PC in any case shall entitle the PC to any
other or further notice or demand in similar or other circumstances.

delivered to any party in connection with this Agreement shall be in writing and

                                                to Management Services Agreement

                           [FORM OF SECURITY AGREEMENT
                   (Management Company's Accounts Receivable)]

                                              SECURITY AGREEMENT dated as
                                         of _____ __, 1995, between MAJEAN 
                                         SUB 2, INC., a Delaware corporation
                                         (the "Management Company"), and
                                         ADVANCED HEART INSTITUTE OF NEW
                                         YORK, P.C., a New York professional
                                         corporation (the "PC").

     Reference is made to the Management Services Agreement dated as of August
7, 1995 among the PC, Valavanur A. Subramanian, M.D., Jeffrey Moses, M.D., and
the Management Company (the "Management Services Agreement")

     In order to secure the Management Company's obligations to the PC under
Section 14(c)(ii) of the Management Services Agreement, the Management Company
has agreed to grant to the PC a security interest in all of the Management
Company's accounts receivable, by entering into this Agreement with the PC.

     ACCORDINGLY, in consideration of the premises and the mutual covenants and
agreements contained in this Agreement, and for other good and valuable
consideration the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

     SECTION 1. Definitions. (a) As used in this Agree- ment, the following
terms shall have the following meanings:

     "Collateral" means all of the Management Company's accounts receivable,
irrespective of the form thereof, whether now owned or existing or hereafter
acquired or arising and regardless of where located, including, without
limitation, accounts receivable purchased from the PC pursuant to Section 8(a)
of the Management Services Agreement.

     "Event of Default" means any default by the Management Company in the
payment or performance of any Obligation and the continuance of such default for
a period of five days after notice thereof from the PC.

     "Obligations" means any and all obligations and liabilities of the
Management Company to the PC arising out of Section 14(c)(ii) of the Management
Services Agreement.

     "UCC" means the Uniform Commercial Code as in effect on the date hereof in
the State of New York; provided, 


<PAGE>

however, that if by reason of mandatory provisions of law, the perfection or the
effect of perfection or non-perfection of the Security Interest in any
Collateral is governed by the Uniform Commercial Code as in effect in a
jurisdiction other than New York, "UCC" means the Uniform Commercial Code as in
effect in such other jurisdiction for purposes of the provisions hereof relating
to such perfection or effect of perfection or non-perfection.

     (b) Unless otherwise defined herein, or unless the context otherwise
requires, all terms used herein which are defined in the UCC shall have the
meanings ascribed to them in the UCC.

     (c) Capitalized terms used and not defined in this Agreement have the
meanings ascribed to them in the Management Services Agreement.

     (d) The definitions in this Section 1 shall apply to the singular and
plural forms of the terms defined. Whenever the context requires, any pronoun
shall include the corresponding masculine, feminine and neuter forms. The words
"include," "in- cludes" and "including" shall be deemed to be followed by the
phrase "without limitation."

     (e) Unless otherwise specified, references in this Agreement to any Section
are references to such Section in this Agreement and references in any Section
or definition to any clause are references to such clause of such Section or
definition.

     SECTION 2. Grant of Security Interest. In order to continue to secure to
the PC the full and punctual payment (whether at stated maturity, by
acceleration or otherwise) and performance by the Management Company of all of
its Obligations, the Management Company hereby pledges, assigns, conveys,
hypothecates and transfers for security to the PC a continuing lien on and
continuing first priority security interest (the "Security Interest") in, all of
Management Company's right, title and interest in, to and under the Collateral.
The Security Interest is granted as security only and shall not subject the PC
to, or transfer or in any way affect or modify, any obligation or liability of
the Management Company with respect to any of the Collateral or any transaction
arising in connection therewith.

     SECTION 3. Rights and Remedies Upon Default. 

     1. Generally. If an Event of Default shall have occurred and be continuing,
the PC may exercise all rights of a secured party under the UCC, and, in
addition, the PC shall have (i) all of the rights and remedies provided for in
this Agreement and (ii) all of the rights and remedies to which a secured party
is entitled under the laws in effect in any jurisdiction where any rights and
remedies hereunder may be asserted, including, to the maximum extent permitted
by law, the right to exercise all 


                                       2
<PAGE>

voting, consensual and other powers of ownership pertaining to the Collateral as
if the PC were the sole and absolute owner thereof (and the Management Company
agrees to take all such action as may be appropriate to give effect to such
right).

     2. Sale of the Collateral. (a) If an Event of Default shall have occurred
and be continuing, the PC may, without being required to give any notice (except
as may otherwise be required by this Agreement or by Applicable Law), sell the
Collateral or any part thereof at public or private sale, for cash, upon credit
or for future delivery, and at such price or prices as the PC may deem
satisfactory. The PC may be the purchaser of any or all of the Collateral so
sold at any public sale, or, if the Collateral is of a type customarily sold in
a recognized market or is of a type which is the subject of widely distributed
standard price quotations, at any private sale. The Management Company will
execute and deliver such documents and take such other action as the PC deems
necessary or advisable in order that any such sale may be made in compliance
with law. Upon any such sale the PC shall have the right to deliver, assign and
transfer the Collateral so sold to the purchaser thereof. Each purchaser at any
such sale shall hold the Collateral so sold to it absolutely and free from any
Lien or other claim or right of whatever kind, including any equity or right of
redemption of the Management Company which may be waived, and the Management
Company, to the extent permitted by law, hereby specifically waives all rights
of redemption, stay or appraisal which it has or may have under any law now
existing or hereafter enacted or adopted (as well as any rights to exoneration,
subrogation or reimbursement arising at law, in equity or otherwise).

     (b) The PC shall give the Management Company not less than ten (10) days'
prior written notice of the time and place of any such sale or other intended
disposition of any of the Collateral, except any Collateral which threatens to
decline speedily in value or is of a type customarily sold on a recognized
market, and the Management Company agrees that such notice constitutes
"reasonable notification" within the meaning of, and for all purposes of, the
applicable provisions of the UCC. Any notice of such sale required by this
Agreement shall, in case of a public sale, state the time and place fixed for
such sale, and in the case of a private sale, state the day after which such
sale may be consummated. Any such public sale shall be held at such time or
times within ordinary business hours and at such place or places as the PC may
fix in the notice of such sale. At any such sale the Collateral may be sold in
one lot as an entirety or in separate parcels, as the PC may determine. The PC
shall not be obligated to make any such sale pursuant to any such notice. The PC
may, without notice or publication, adjourn any public or private sale or cause
the same to be adjourned from time to time by announcement at the time and place
fixed for the sale, and such sale may be made at any time or place to which the
same may be so adjourned. In the case of any sale of all or any part of the
Collateral on credit or for future delivery, the 


                                       3
<PAGE>

Collateral so sold may be retained by the PC until the selling price is paid by
the purchaser thereof, but the PC shall not incur any liability in case of the
failure of such purchaser to take up and pay for the Collateral so sold and, in
case of any such failure, such Collateral may again be sold as permitted by and
in accordance with this Agreement, including the application of proceeds as set
forth herein.

     3. Other Rights. In addition to, and not in limitation of any rights or
remedies of the PC contained elsewhere in this Agreement, if an Event of Default
shall have occurred and be continuing, the PC may require the Management Company
to, and the Management Company agrees that it will, at its expense and upon the
request of the PC, forthwith assemble all or any part of the Collateral as
directed by the PC and make it available at a place designated by the PC which
is, in the PC's opinion, reasonably convenient to the PC, whether at the
premises of the Management Company or otherwise.

     4. General Authority. Effective only upon the occurrence and during the
continuance of an Event of Default, the Management Company hereby appoints the
PC its true and lawful attorney, with full power of substitution, in the name of
the Management Company or otherwise, for the sole use and benefit of the PC, but
at the expense of the Management Company, to exercise any power permitted by
Applicable Law with respect to any Collat- eral, which appointment is
irrevocable and coupled with an inter- est. Without limiting the generality of
the foregoing, the PC shall have the right (but not the obligation), upon the
occurrence and during the continuance of an Event of Default to:

          (a) demand, sue for, collect, receive and give acquittance for any and
     all monies or property due or to become due on account or in exchange for
     any of the Collateral or by virtue of the Collateral;

          (b) settle, compromise, compound, prosecute or defend any action or
     proceeding with respect to or other- wise affecting the Collateral;

          (c) sell, transfer, assign or otherwise deal therein or therewith or
     the proceeds or avails of the Collateral, as fully and effectually as if
     the PC were the absolute owner thereof;

          (d) extend the time of payment of any or all accounts or other
     obligations owed to the Management Company and to make any allowance and
     other adjustments with reference thereto;

          (e) notify or direct the Management Company to notify any or all
     account debtors that the accounts have been assigned to the PC, for the
     ratable benefit of the Lenders, and that the PC has a security interest
     therein (the PC shall promptly furnish the Management Company with a 


                                       4
<PAGE>

     copy of any such notice, and the Management Company hereby agrees that any
     such notice, in the PC's sole discretion, may be sent on the Management
     Company's stationery);

          (f) contact account debtors for any reason, including to direct or
     cause the Management Company to direct account debtors to make all payments
     due from them to the Management Company upon the accounts directly to or as
     directed by the PC;

          (g) prior to the disposition of the Col- lateral, use, operate and
     control the Collateral to preserve the Collateral or its value, store or
     transfer the Collater- al without charge in or by means of any storage or
     transpor- tation facility owned or leased by the Management Company, or
     process, repair or recondition the Collateral or otherwise prepare it for
     disposition in any manner and to the extent the PC deems appropriate;

          (h) use the information recorded on or contained in any data
     processing equipment and computer hardware and software relating to the
     accounts and other obligations owed to the Management Company to which the
     Management Company has access (subject to the proprietary rights applicable
     to such computer hardware and software) and do any other act or thing
     necessary, in the PC's sole discretion, to fulfill the Management Company's
     obligations to the PC under this Agreement or otherwise;

          (i) make any payments and do any other acts which the PC deems
     desirable to protect the Security Interest in the Collateral, including
     paying, purchasing, contesting or compromising any Lien which, in the
     judgment of the PC, appears to be prior to or superior to the Security
     Interest, and to appear in and defend any action or proceeding purporting
     to affect the Security Interest and/or the value of the Collateral, and in
     exercising any such power or authority, to pay all reasonable expenses
     incurred in connection therewith, the Management Company's obligation with
     respect to the repayment thereof being secured under this Agreement; and

          (j) receive, endorse and collect all checks made payable to the order
     of the Management Company representing any payment in respect of the
     Collateral or any part thereof and to give full discharge for the same.

     5. Deficiency. If the proceeds of the sale, collection or other realization
of or upon all or part of the Collateral pursuant to the provisions of this
Agreement are insufficient to cover the costs and expenses of such realization
and the payment in full of the Obligations, the Management Company shall remain
liable for any deficiency.


                                       5
<PAGE>


     SECTION 4. Duration of Agreement; Release of Security. This Agreement and
the Security Interests shall terminate at midnight on December 31, 1995. The
release of Collateral or reassignment of rights to the Management Company upon
the termination of this Agreement shall be without recourse to or warranty by
the PC and shall be made by the PC at the expense of the Management Company.
Upon the release of Collateral or reassignment of rights to the Management
Company, the PC will, at the expense of the Management Company, execute and
deliver to the Management Company such documents as the Management Company shall
reasonably request to evidence such release or reassignment.

     SECTION 5. Management Company Remains Liable. Anything contained in this
Agreement to the contrary notwithstanding, (a) the Management Company shall
remain solely liable to perform its duties and obligations under the contracts
and agreements included in the Collateral to the extent set forth therein to the
same extent as if this Agreement had not been executed, (b) the exercise by the
PC of any of its rights and remedies hereunder shall not release the Management
Company from any of its duties or obligations under the contracts and agreements
included in the Collateral except to the extent the exercise of such rights
renders the performance of such duties or obligations by the Management Company
impracticable under any such agreement or contract, and (c) the PC shall not
have any obligation or liability under any contract or agreement included in the
Collateral by reason of this Agreement, and the PC shall not be obligated in any
manner to perform any of the obligations or duties of the Management Company
thereunder or to take any action to collect or enforce any claim for payment
assigned hereunder, except to the extent that the PC has expressly and
affirmatively assumed the rights and the obligations and duties of the
Management Company under any such contract or agreement.

     SECTION 6. Limitation on Duty of the PC Regarding the Collateral. Beyond
the exercise of reasonable care in the custody of the Collateral, the PC shall
have no duty as to any Collateral in its possession or control or in the
possession or control of any agent or bailee, or any income thereon, or as to
the preservation of rights against prior parties or any other rights pertaining
thereto. The PC shall be deemed to have exercised reasonable care in the custody
of the Collateral in the PC's possession if the Collateral is accorded treatment
substantially equal to that which the PC accords its own property or to that
which the PC accords to the property of others that the PC holds as a secured
party. The PC shall not be liable or responsible for any loss or damage to any
of the Collateral, or for any diminution in the value thereof, by reason of the
act or omission of any warehouseman, carrier, forwarding agency, consignee or
other agent or bailee selected by the PC in good faith.

     SECTION 7. Security Interest Absolute. All rights of the PC hereunder, the
grant of the security interest in the Collateral and all obligations of the
Management Company hereunder 


                                       6
<PAGE>

shall be absolute and unconditional irrespective of (a) except to the extent not
permitted to be waived under Applicable Law, any lack of validity or
enforceability of the Obligations, (b) any change in the time, manner or place
of payment of, or in any other term of, all or any of the Obligations, or any
other amendment or waiver of or any consent to any departure from the PC
Agreement or any other agreement or instrument relating to any of the foregoing,
(c) failure by the PC to take steps to perfect or maintain perfected its
security interest in, or to preserve its rights to, any of the Collateral, (d)
any exchange, release or non-perfection of any other collateral, or any release
or amendment or waiver of or consent to or departure from any guaranty, for all
or any of the Obligations, (e) the disallowance under Section 502 of the
Bankruptcy Code of all or any portion of the claims of the PC for repayment of
the Obligations or (f) any other circumstance which might otherwise constitute a
legal or equitable defense available to, or a legal or equitable discharge of,
the Management Company with respect to the Obligations other than the
indefeasible payment in full of all of the Obligations.

     SECTION 8. No Waiver By the PC. No failure on the part of the PC to
exercise, and no delay in exercising and no course of dealing with respect to,
any right or power under this Agreement shall operate as a waiver thereof, nor
shall any single or partial exercise by the PC of any right or power under this
Agreement, or any abandonment or discontinuance of steps to enforce such right
or power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights of the PC in this Agreement are cumulative and
are not exclusive of any other rights or remedies available to the PC at law or
in equity. No notice to or demand on the Management Company in any case shall
entitle the Management Company to any other or further notice or demand in
similar or other circumstances.

     SECTION 9. Notices. All notices, demands and requests of any kind to be
delivered to any party in connection with this Agreement shall be in writing and
shall be (a) delivered personally, (b) sent by nationally-recognized overnight
courier, (c) sent by first class, registered or certified mail, return receipt
requested or (d) sent by facsimile, in each case to such party at its address as

                                             MANAGEMENT SERVICES AGREEMENT (this
                               "Agreement") is entered into as of July 1, 1996
                               by and between SPECIALIST PHYSICIANS MANAGEMENT,
                               INC., a Delaware corporation (the "Management 
                               Company"), and CARDIOLOGY FIRST OF NEW JERSEY,
                               P.A., an independent physicians association (the
                               "Network").

                                   WITNESSETH:

     A. The Network is an independent physician association that contracts with
various health maintenance organizations, insurance carriers, self-funded
employers, union trust funds, and other third party payors (collectively,
"payors"), and that provides or otherwise makes available medical services in
New Jersey to persons enrolled in payor health care plans. The Management
Company has, or has the ability to procure, management and administrative
resources and services essential to the Network's operations.

     B. The Network and the Management Company desire to contract for the
provision of such resources and services in accordance with the terms and
conditions contained in this Agreement.

     NOW, THEREFORE, in consideration of the mutual covenants, premises and
agreements herein contained and the mutual benefits to be derived therefrom, the
Management Company and the Network agree as follows:

     SECTION 1. Engagement of the Management Company; Term and Termination.

     1.1. Engagement.

     The Network hereby engages the Management Company, and the Management
Company hereby agrees and confirms its engagement by the Network, to provide the
administrative and management services necessary for the operations of the
Network (the "Services"), including, but not limited to, the services described
on Schedule I; provided, however, that if the Network requests a service that is
not identified on Schedule I, then the Management Company may either (a) notify
the Network of its inability to provide the requested service and, in such
event, have no obligation or liability to the Network with respect thereto, or
(b) take such action as the Management Company may deem necessary or appropriate
to adequately perform such service within a reasonable period of time after
request therefor was 


<PAGE>

made; provided that in such case the Network shall pay such
additional fees to the Management Company as then agreed by the parties.

     1.2. Term.

     The term of this Agreement shall commence effective as of the date hereof
(the "Effective Date") and shall continue until the fifth anniversary of the
Effective Date (the "Initial Term"), unless sooner terminated or extended
pursuant to the terms hereof. After the Initial Term, the Network shall have the
right to extend this Agreement for an additional three year term (the "Option
Term") by providing written notice to the Management Company of the Network's
election to so extend not later than 120 days prior to the end of the Initial
Term. After the Option Term, this Agreement shall automatically renew for
successive three year terms, unless the Management Company or the Network gives
written notice of its intent to terminate not less than 90 days prior to the end
of the then expiring term.

     1.3. Termination.

     (a) The Network may terminate this Agreement, upon a 45-day written notice
to the Management Company, on either (i) the first anniversary of the Effective
Date, provided that on such date (A) the Network has failed to obtain at least
50,000 capitated lives under new managed care contracts or through the extension
or expansion of existing managed care contracts or (B) Advanced Health
Management Corporation, a Delaware corporation ("AHM"), is unwilling to fund its
pro rata share, based on the equity ownership of the Management Company, of the
reasonable working capital needs of the Management Company in excess of Original
Working Capital (as defined below); or (ii) the 36-month anniversary of the
Effective Date, provided that on such date the Network has failed to obtain at
least 100,000 capitated lives under new managed care contracts or the extension
or expansion of existing managed care contracts. For the purposes of this
Agreement, a "managed care contract" shall be any contract, agreement or
understanding pursuant to which the Network is to provide medical services
consistent with its then existing practice to patients covered by a particular
managed care company, health maintenance organization or other medical insurance
provider. "Original Working Capital" shall mean working capital funding that AHM
alone is responsible for providing to the Management Company in cash up to an
aggregate amount not to exceed $150,000 as necessary to fund any operating
deficit of the Management Company.

     (b) The Management Company may terminate this Agreement, upon a 45-day
written notice to the Network, on either (i) the first anniversary of the
Effective Date, provided that (A) AHM is then unwilling to fund its pro rata
share, based on the equity ownership of the Management Company, of the
reasonable working capital needs of the Network in excess of the Original


                                       2
<PAGE>

Working Capital of the Management Company or (B) the Network has failed to
obtain at least 50,000 capitated lives under new managed care contracts or the
extension or expansion of existing managed care contracts; or (ii) the 36-month
anniversary of the Effective Date, provided that on such date the Network has
failed to obtain at least 100,000 capitated lives under new managed care
contracts or the extension or expansion of existing managed care contracts.

     (c) This Agreement may be terminated for "cause" by either party upon
written notice of termination to the defaulting party specifying with
particularity the event that justifies such termination. No delay or failure to
transmit such notice shall constitute a waiver of any such event or of any other
or further event. If the defaulting party shall fail within 45 days after the
receipt of such notice to cure or correct the default alleged in the notice, the
non-defaulting party shall have the right to terminate this Agreement, such
termination to be effective as of the date specified in such notice of
termination, or, alternatively, immediately upon the defaulting party's failure
to cure by the end of the 45 day period; provided, however, that if such default
is not capable of correction within such 45 day period, and if the defaulting
party shall commence corrective action within that 45 day period and pursue the
corrective measures promptly and with due diligence, then the effective date of
termination will be deferred for a period not in excess of 45 days beyond the
initial 45 day period so long as the defaulting party continues to pursue
corrective measures. In the event any such default is in fact cured during any
such period the notice of termination shall be null and void. As used herein,
the term "cause" shall mean (a) the failure by either party to reasonably
perform or observe any of its obligations under this Agreement, (b) the loss of
the ability of either party lawfully to perform any of its obligations hereunder
or (c) the dissolution of the Network.

     SECTION 2. Payment for Services; Budget Process.

     2.1. Payment.

     In consideration for the provision of the Services, the Network shall pay
to the Management Company the Service Fee and the Incentive Fee as set forth on
Schedule II.

     2.2. Allocation of Certain Expenses.

     It is expressly acknowledged that certain of the Services shall be
performed by personnel employed by the Management Company (or the Management
Company's affiliates) who are not dedicated exclusively to the provision of
Services under this Agreement. The Network and the Management Company agree to
allocate the actual costs and expenses of such personnel (including, but not
limited to, salaries, benefits programs, and FICA and FUTA contributions) to the
Service Fee in proportion to 


                                       3
<PAGE>

the percentage of time the personnel are dedicated to the provision of Services
under this Agreement. Similarly, the Network and the Management Company agree 
to allocate the actual costs and expenses of office facilities, equipment and 
other resources to the Service Fee proportionate to the dedication of such 
resources to the Services provided under this Agreement. All such allocations 
shall be made by mutual agreement in accordance with the budget process set 
forth in Section 2.4 and subject to Section 3.4. The Management Company 
acknowledges that it is not the intent of the Management Company to allocate to 
the Service Fee expenses relating to the Management Company's senior management 
who participate in the provision of Services on only an incidental basis. The 
parties shall allocate a stipend for local medical management of the Network, 
including, without limitation, a Network medical director (the "Medical 
Director") whose role will expand with the development of the Network.

     2.3. Process and Method of Payment.

     (a) The Service Fee shall be billed to the Network on a monthly basis, and
shall be paid by the Network within five days following receipt of such bill.
The bill shall identify and include all actual costs and expenses incurred by
the Management Company in the provision of the Services plus the allocated costs
agreed to during the budget process set forth in Section 2.4 and reflected in
the budget then in effect. At the reasonable request of the Network, the
Management Company shall provide the Network with any supporting documentation
relating to the Service Fee.

     (b) The Incentive Fee shall be paid at the time of the distribution of any
risk pools, incentive pools, incentive payments or any other risk-sharing
arrangement referenced in the definition of Incentive Fee as set forth on
Schedule II.

     (c) Payment of the Service Fee and the Incentive Fee shall be by federal
funds wire transfer to the account of the Management Company or such other means
as the Management Company may, by notice in writing, direct.

     2.4. Budget Process.

     The initial budget for the Services is attached to this Agreement as
Schedule III and incorporated by this reference (the "Initial Budget"). The
- ------------
Network and the Management Company shall meet periodically (but not less than
every six months) to evaluate the level of and need for Services and negotiate a
revised budget of costs and expenses, including, if necessary, a reallocation of
the personnel, facilities and other resources dedicated to the Services and the
related allocation of expenses. Any revised budget shall set forth, among other
relevant information, (a) the initial Services provided under this Agreement,
(b) the employees of the Management Company (or the Management Company's
affiliates) that will be dedicated to the performance of the Services (and, with
respect to each such employee, an agreed upon allocation of time and costs
attributed to the Services and related Service Fee), (c) the estimated cost of
providing the Services for a six-month period (each, a "Period") and (d) the
office facilities, equipment (including computer and hardware)and other
resources necessary provision of the Services (and an allocation of costs 
attributed to the Service Fee). Following the conclusion of a Period, there 
will be an adjustment in the Service Fee (an "Adjustment") to reflect any 
difference between the actual costs and expense incurred by the Management 
Company in the provision of the Services and the Service Fee paid during that 
Period; provided, however, that in no event shall such Adjustment cause the 
        --------  -------
Service Fee payable for risk-based contracts for which professional services 
and hospital services have been capitated to exceed [ ]* percent of the 
Network's capitated service revenues collected during such Period.

     SECTION 3. Additional Agreements Regarding the Services.

     3.1. Standard.

     The Management Company shall perform the Services in a manner that
reasonably supports the competent, cost-efficient

operation, administration and management of the nonmedical aspects of the
Network's operations. The Services shall meet the standards of services utilized
or provided by the Management Company in its own operations. The Management
Company will supervise and manage, or cause to be supervised and managed, the
individuals providing the Services in a manner consistent with the supervision
and management of individuals (including its employees) performing services in
its own operations.

     3.2. The Network's Designated Representative.

     The Network shall identify the person(s) designated by the Network in
writing to act on its behalf under this Agreement (whether one or more, the "the
Network Representative"). Until the Management Company receives notice in
writing of any change in the Network Representative, the Management Company
shall be entitled to rely upon directions and approvals from the most recently
designated Network Representative. In any situation in which, pursuant to the
terms hereof, the Network shall be required or permitted to take any action, or
to give any approval, the Management Company shall be entitled to rely upon the
statement of the Network Representative to the effect that any such action or
approval has been taken or given. In the event the Network Representative does
not respond to a request by the Management Company for any approval or consent
under this Agreement within 10 days after receipt of such request, the request
shall be deemed to be approved.

     3.3. Parties Performing the Services.

     It is agreed that, in performing the Services, the Management Company may
provide the Services directly, may retain, on behalf of the Network, qualified
outside parties to provide the Services, or may delegate the provision of the
Services to the Management Company's affiliates.

     3.4. Record Retention; Auditing Rights.

     The Management Company shall maintain during the term of this Agreement and

disclosed to the Network pursuant to this Agreement and (b) the actual amount of
revenues of the Network and/or the costs and expenses of the Management Company
as determined by the audit, which errors or discrepancies are in the aggregate
(after netting any and all such errors and discrepancies relating to revenues
against any and all such errors and discrepancies relating to costs and
expenses) in excess of five percent for the Period being audited, and which, if
corrected, would favor the Network, then the Management Company shall (x)
reimburse the Network's reasonable out-of-pocket costs incurred in conducting
the audit and (y) pay the Network a dollar amount that is equal to the net
amount of any and all such errors and discrepancies.

the Network may ensure the receipt of quality administrative services,
facilities and other resources, in the absence of bad faith on the part of
either party hereto, the Network and the Management Company hereby waive any and
all claims of conflict of interest relating to this Agreement and the provision

directly or indirectly, may at any time and from time to time own, manage,
operate, market, join, control, or participate in the ownership, management,
marketing, operation, or control of a physician network, independent physician
association, management services organization or other managed care organization
that primarily provides cardiovascular medical services of comparable scope to
the Network that compete directly with the Network in, or in counties adjacent

                     DESCRIPTION OF ADMINISTRATIVE FUNCTIONS
                 PROVIDED BY AUTOMATED CLAIMS MANAGEMENT SYSTEM

     The Management Company will implement an automated claims management
system. With the automated claims management system, on-line verification of
both current and past membership can be obtained including benefits and types of
coverage. Tracking of all referrals (both in and out of system) and the
associated IBNR's payable is available. The automated claims management system
can track the date a claim was received, as well as the date it was paid, and
generate a lag analysis report. It will also track redirected claims, denials,
and services provided by capitated providers. Reports, such as per member per
month, costs by specialty, and number of visits, are generated on a monthly
basis. Additional reports and customized data are available upon request.
Utilization review is enhanced by requiring all non-compliant referrals to be
authorized by the Network's Medical Director in addition to being reviewed by
the Management Company. The referral screen will also indicate whether or not
the referral was either a normal referral, inpatient, outpatient, COB or denied.

          SECTION 2.  BOARD OF DIRECTORS.  (a) The business and affairs of the
                      ------------------
Corporation shall be managed by or under the direction of a Board of Directors
(the "Board of Directors") consisting of seven directors, four of whom shall be
designated by AHM and three of whom shall be designated by SPM.  At each annual
meeting of the stockholders of the Corporation, and at each special meeting of
the stockholders of the Corporation called for the purpose of electing directors
of the Corporation, and at any time at which the Stockholders shall have the
right to, or shall, vote or give their written consent to elect directors of the
Corporation, then, and in each event, the Stockholders shall vote all shares of
Stock owned by them (or shall consent in writing in lieu of a meeting of
stockholders of the Corporation, as the case may be) for the election of the
directors designated in accordance with the preceding sentence.  In the event of
the removal, resignation or death of a director, the Stockholders shall vote, or
give their written consent, to fill the resulting vacancy with a nominee
selected by the Stockholder originally entitled to designate such director. 
Notwithstanding anything contained herein to the contrary, SPM's right to
designate three directors to serve on the Board of Directors shall be
nonassignable and shall terminate as of the date SPM owns in the aggregate less

          (b)  Except for the actions of the Board of Directors relating to
authorizing the Corporation to (i) participate in the Rollup (as defined below)
transactions contemplated pursuant to Section 3 hereof and (ii) repurchase from
SPM shares of Stock pursuant to Section 6.1 hereof, for which such actions a
quorum shall exist if a majority of the directors of the Corporation then in
office are present at any meeting of the Board of Directors, a quorum at any
meeting of the Board of Directors shall exist if a majority of the directors
then in office are present and at least one director designated by AHM and one
director designated by SPM are present at such meeting.

          (c)  Except for the actions of the Board of Directors relating to
authorizing the Corporation to (i) participate in the Rollup (as defined below)
transactions contemplated pursuant to Section 3 hereof and (ii) repurchase from
SPM shares of Stock pursuant to Section 6.1 hereof, which such actions shall
require the approval of a majority of the directors then in office, any and all
other actions to be taken by the Board of Directors shall require the approval
of a majority of the directors then in office, including the approval of one
director designated by AHM and one director designated by SPM.  AHM shall at all
times have the right to elect the Chairman of the Board of Directors.

          SECTION 3.  ROLLUP OF SPM'S STOCK. 
                      ---------------------

          (a)  If AHM's Board of Directors determines that the Trigger Event (as
defined below) has occurred, then AHM may elect to merge the Corporation with
and into AHM in a transaction in which SPM shall receive voting common stock of
AHC (the "AHC Stock") in exchange for its Stock of the Corporation (the
"Rollup").  Each share of Stock owned by SPM shall be convertible into that
number of shares of AHC Stock to be determined at the time of the Rollup in
accordance with Exhibit A.
                ---------

          (b)  A "Trigger Event" shall be deemed to have occurred if each of the
following conditions is satisfied in full:  (i) AHM is providing Practice
Management Services to at least 300 physicians, (ii) AHM is providing Network
Management Services to at least 2,000 physicians, (iii) AHC has at least
$75,000,000 in stockholders' equity according to AHC's most recent financial
statements, (iv) AHC maintains stock outstanding which is publicly traded on a
national stock exchange and (v) AHC's Board of Directors has authorized the
Rollup.  

          (c)  The right of SPM to participate in the Rollup and to receive
shares of AHC Stock pursuant to Section 3(a) hereof shall automatically
terminate if, prior to the completion of the Rollup, (i) the Corporation has
terminated all of the Management Services Agreements entered into between the
Corporation and the Networks with cause pursuant to Section 1.3(c) thereof or
(ii) any Management Services Agreement between the Corporation and a Network (a
"Terminated Network") in which a Member [as such terms are defined in the
Operating Agreement dated as of March 15, 1996 (the "Operating Agreement"),
between SPM and the Members thereto] holds an ownership interest is terminated
by the Corporation with cause pursuant to Section 1.3(c) thereof, unless, within
60 business days after the effective date of such termination (x) a Member or
Members, other than a Member who or which holds an ownership interest in a
Terminated Network, holding Units (as such term is defined in the Operating
Agreement) in SPM exchanges or exchange such Units for all of SPM's Stock in the
Corporation pursuant to the provisions of the Operating Agreement, or (y) all
Members who or which hold an ownership interest in a Terminated Network Sell to
SPM, pursuant to the terms of the Operating Agreement, all of the Units in SPM
held by such Member.  In the event a Member acquires all or part of SPM's Stock
in the Corporation pursuant to clause (x) above, SPM shall cause each such
Member to enter into a written agreement to be bound by the terms of this
Agreement.  AHC shall not be obligated to issue AHC Stock in the Rollup to any
Member that fails to enter into a written agreement at the time such Member
acquires all or part of SPM's Stock in the Corporation pursuant to clause (x)
above.  In the event of the occurrence of either of the events set forth in this
Section 3(c)(i) or (ii), SPM shall promptly surrender and deliver to the
Corporation any and all stock certificates evidencing SPM's ownership of the
Stock in a form sufficient to convey to the Corporation good

title to the Stock and free and clear of any and all encumbrances, liens
pledges, security interests, mortgages, charges, easements, reservations,
options, rights of first refusal and other restrictions of any kind.

          SECTION 4.  MANDATORY REPURCHASE OF SPM STOCK.
                      ---------------------------------

               (a)  If AHM has failed to commence the Rollup by the first
anniversary of the occurrence of the conditions set forth in Section 3(b)(i)
through (iv) hereof, SPM shall be entitled to require AHM, and AHM shall be
obligated (subject to the following sentence), to repurchase all of the
outstanding Stock owned by SPM (the "Put Option") at a purchase price equal to
110 percent of the fair market value of such Stock had the Rollup been
consummated pursuant to Section 3.  The fair market value of the Stock subject
to the Put Option shall be the average publicly traded price per share of AHC's
Stock quoted on a national stock exchange for the 30 consecutive trading days
immediately prior to SPM's exercise of the Put Option multiplied by the number
                                                      ----------
of shares of such Stock then owned by SPM.  In the event that a quote of the
price of AHC's Stock is unavailable on a national stock exchange, the
determination of fair market value shall be made by a nationally recognized
independent public accounting firm or an investment banking firm mutually agreed
to by AHM and SPM which is independent of and not affiliated with AHM, SPM or
any of their Affiliates.  Any determination of fair market value shall be
conclusive and binding on AHM and SPM.  AHM and SPM shall equally bear the cost
of any such appraisal.

               (b)  SPM may exercise the Put Option by delivering a written
notice (the "Put Notice") to AHM which notice shall specify the number and
percentage of shares of Stock owned by SPM to be repurchased.

               (c)  The closing of such repurchase by AHM shall occur on a date
determined by AHM (the "Put Closing Date") which date shall be no more than 30
days after the determination by the independent appraiser of fair market value
of the Stock subject to the Put Option.  On the Put Closing Date, SPM shall
surrender to AHM the Stock owned by SPM being repurchased without any
representation or warranty (other than that the holder has good and valid title
thereto free and clear of liens, claims, encumbrances and restrictions of any
kind), against payment therefor by AHM to SPM by (at the option of SPM), (i)
wire transfer to an account in a bank located in the United States designated by
SPM for such purpose or (ii) a certified or official bank check drawn on a
member of the New York Clearing House payable to the order of SPM.

     hereto to be bound by and comply with all applicable provisions of this
     Agreement to the same event as if it were the Stockholder making such

     with Section 3 hereof;

             (iii)  SPM may Sell its Stock to the Members (as defined in the
     Operating Agreement) pursuant to the terms of the Operating Agreement;

             (iv)   by Sale in accordance with Section 4 or 5.2;

              (v)  AHM shall have the right to Sell all or any part of its Stock
     to any Affiliate, or any employee of AHM or any Affiliate, who or which
     agrees in writing to be bound by and to comply with the applicable
     provisions of this Agreement as if such purchaser were AHM for the purposes
     hereof;

              (vi)  SPM shall be permitted to sell its Stock to AHM or the
     Corporation; 

               (vii)   pursuant to a liquidation or winding-up of the
     Corporation.

          5.2.  RIGHT OF FIRST REFUSAL.  Except as otherwise provided in Section
                ----------------------
5.1, SPM and AHM shall not Sell any shares of Stock unless (i) the prior written
consent of the Corporation is obtained or (ii) the following procedure is
followed:

          (a)  The Selling Stockholder shall first deliver to the Corporation
and the Non-selling Stockholders a written notice (the "Offer Notice"), which
shall be irrevocable for a period of 90 days after delivery thereof, offering
(the "Offer") all of the Stock proposed to be Sold by the Selling Stockholder at
the purchase price and on the terms specified in the Offer Notice.  The
Corporation (or its designee) shall then have the right and option, for a period
of 30 days after delivery of the Offer Notice, to accept all or any part of the
Stock so offered at the purchase price and on the terms stated in the Offer
Notice.  Such acceptance shall be made by delivering a written notice to the
Selling Stockholder and the Non-selling Stockholders within said 30-day period. 


          (b)  If the Corporation (or its designee) shall fail to accept all of
the Stock offered for sale pursuant to, or shall reject in writing, the Offer
(the Corporation being required to notify in writing the Selling Stockholder and
the Non-selling Stockholders of its rejection or failure to accept all of the

<PAGE>
Stock in the event of the same), then, upon the earlier of the expiration of
such 30-day period or the receipt of such written notice of rejection or failure
to accept such Offer by the Corporation, the Non-selling Stockholders shall have
the right and option, for a period of 30 days thereafter, to accept all or any
part of the Stock so offered and not accepted by the Corporation (the "Refused
Stock") at the purchase price and on the terms stated in the Offer Notice.  Such
acceptance shall be made by delivering a written notice to the Corporation and
the Selling Stockholder within said 30-day period.  

          (c)  Sales of Stock under the terms of Sections 5.2(a) and 5.2(b)
shall be made at the offices of the Corporation on a mutually satisfactory
business day within 30 days after the expiration of the last applicable period
described in Section 5.2(b).  Delivery of certificates or other instruments
evidencing such Stock duly endorsed for transfer shall be made on such date
against payment of the purchase price therefor.  

          (d)  If effective acceptance shall not be received pursuant to
Sections 5.2(a) and 5.2(b) with respect to all Stock offered for Sale pursuant
to the Offer Notice, then the Selling Stockholder may Sell all or any part of
the Stock so offered and not so accepted to a party or parties reasonably
acceptable to the Non-selling Stockholders (determined in accordance with
Section 5.2(e) hereof) at a price not less than the price, and on terms not more
favorable to the purchaser thereof than the terms stated in the Offer Notice at
any time within 60 days after the expiration of the Offer required by Sections
5.2(a) and 5.2(b).  In the event that the Stock is not Sold by the Selling
Stockholder during such 60-day period to such party or parties, the right of the
Selling Stockholder to Sell such Stock shall expire and the obligations of this
Section 5.2 shall be reinstated.

          (e)  The Selling Stockholder shall, at least 20 days prior to the
proposed date of Sale of Stock by the Selling Stockholder to any party other
than the Non-selling Stockholders, provide in writing to the Non-selling
Stockholders the identity of such proposed purchaser and such other information
concerning such purchaser as shall be reasonably requested by the Non-selling
Stockholders to enable the Non-selling Stockholders to determine the
acceptability of the proposed purchaser as a Stockholder.  Within such 20 day
period, the Non-selling Stockholders shall provide to the Selling Stockholder in
writing either such Stockholder's consent or disapproval of such proposed
purchaser.  The Selling Stockholder shall be entitled to consummate such Sale of
Stock to such proposed purchaser if the Non-selling Stockholders shall consent
to such proposed purchaser.

          (f)  Anything contained herein to the contrary notwithstanding, any
purchaser of Stock pursuant to this Section 5.2 who or which is not a
Stockholder shall agree in writing in advance

with the parties hereto to be bound by and comply with all applicable provisions

                                    ---------


                                   The Rollup
                                   ----------


          AHC has established and reserved 548,224 shares of its common stock as
adjusted by a stock split, reverse stock split, stock dividend or
recapitalization of AHC's shares of common stock (the "MSO Pool") for issuance
to all medical personnel which own, from time to time, any equity interest in
any Affiliate of AHC which provides management services to physicians or
physician groups (each an "MSO").  AHC has organized, and from time to time
after the date hereof shall organize, MSO's to provide physician management and
network services and grant equity interests in such entities, which equity
interests will participate in the MSO Pool or any Rollup.

          The MSO Pool will only be issued if AHC determines, in its discretion,
to consummate the Rollup.  The Rollup of all MSO equity interests must be done
at one time and in one transaction.  The shares in the MSO Pool have been
divided into four tranches, of 17.5%, 22.5% 27.5% and 32.5%, respectively.  AHC
will allocate the first tranche of the MSO Pool ("Tranche I") to be divided
among the physician networks and physician practices (each a "PPN") which own
equity in the MSO's which are established on or prior to December 31, 1996 (the
"Tranche I Period").  AHC will allocate the second tranche of the MSO Pool
("Tranche II") to be divided among the PPNs which own equity in all MSO's which
operate (including MSO's formed during the Tranche I Period) during calendar
year 1997 (the "Tranche II Period").  AHC will allocate the third tranche of the
MSO Pool ("Tranche III") to be divided among the PPN's which own equity in all
MSO's which operate during calendar year 1998 (the "Tranche III Period").  AHC
will allocate the fourth tranche of the MSO Pool ("Tranche IV") to be divided
among the PPNs which own equity in MSO's which operate during calendar year 1999
(the "Tranche IV Period").

          At the time AHC shall determine to effect the Rollup, the MSO Pool
shall be allocated as follows:

          1.   All PPNs which qualify for Tranche I shares shall receive an
allocation of Tranche I shares based upon their proportionate percentage of
Qualifying Revenues for the Tranche I Period.  To determine the proportionate
percentage for each PPN, a numerator for each PPN will be established by taking
the Qualifying Revenues of such MSO for the Tranche I Period.  The denominator
shall be equal to the sum of the numerators for the PPNs.  As used herein,
Qualifying Revenues for each MSO shall mean all revenues other than revenues
derived from referrals for "designated health services" (as such term is defined
by applicable law and regulations or similarly referral regulated services) by
physicians if consideration for such referrals is prohibited by state or federal
law, including federal "STARK" law and regulations.





































<PAGE>
          2.   All PPNs which qualify for Tranche II shares shall receive an
allocation of Tranche II shares based upon their proportionate percentage of
Qualifying Revenue for the Tranche II Period.  The proportionate percentage
shall be calculated as provided in 1 above.

          3.   All PPNs which qualify for Tranche III shares shall receive an
allocation of Tranche III shares based upon their proportionate percentage of
Qualifying Revenue for the Tranche III Period.  The proportionate percentage
shall be calculated as provided in 1 above

          4.   All PPNs which qualify for Tranche IV shares shall receive an
allocation of Tranche IV shares based upon their proportionate percentage of
Qualifying Revenue for the Tranche IV Period.  The proportionate percentage
shall be calculated as provided in 1 above.

          5.   If the Rollup shall occur prior to the end of the Tranche IV
Period but after the end of the Tranche III Period, the Tranche IV shares shall
be allocated as if the Tranche IV Period ended on the date of the Rollup.  If
the Rollup shall occur prior to the end of the Tranche III Period but after the
end of the Tranche II Period, the Tranche III shares shall be allocated as if
the Tranche II Period had ended on the date of the Rollup and the Tranche IV
shares shall be allocated pro rata to all PPNs receiving Tranche I, Tranche II
                          --- ----
and Tranche III shares based upon the number of shares received.  If the Rollup
shall occur prior to the end of the Tranche II Period, the Tranche II shares
shall be allocated as if the Trance II Period had ended on the date of the
Rollup and the Tranche III and IV shares shall be allocated pro rata to all PPNs
                                                            --- ----
receiving Tranche I and II shares based upon the number of shares received.

                                             MANAGEMENT SERVICES AGREEMENT
                                             dated as of July 1, 1996, between
                                             LONG ISLAND   INTERVENTIONAL
                                             CARDIOLOGY, a New  York partnership
                                             (the "Medical Group"), and
                                             DIAMOND PHYSICIAN MANAGEMENT, INC.,
                                             a Delaware corporation (the
                                             "Management Company").

     The Medical Group is a New York partnership involved in providing
interventional cardiology medical services (the "Medical Services") to the
general public. The Management Company is a corporation engaged in the business
of providing administrative, financial, marketing, information technology and
operational services to professional medical organizations (the "Business"). The
Management Company and the Medical Group desire to enter into this Agreement,
pursuant to which, among other things, the Management Company will render
management services to the Medical Group.

     ACCORDINGLY, the Medical Group and the Management Company agree as follows:

     SECTION 1. Retention of the Management Company. (a) The Medical Group
hereby retains the Management Company to provide the management, financial,
marketing, information technology, operational and administrative services (the
"Management Services") described on Schedule I, and the Management Company
accepts such retention, upon the terms and subject to the conditions set forth
herein.

     (b) During the term of this Agreement, the Management Company shall be the
exclusive provider of the Management Services utilized by the Medical Group.
Notwithstanding anything contained herein to the contrary, (i) the Management
Company and the Medical Group intend to act and perform with respect to each
other as independent contractors, and the provisions hereof are not intended to
create any partnership, joint venture, agency or employment relationship between
the parties and (ii) the Management Company is hereby engaged solely to provide
the Management Services to the Medical Group and shall not interfere with,
control, direct or supervise the Medical Group or any licensed medical
professional employed thereby in connection with the provision of the Medical
Services.

     (c) The parties agree that the benefits to the Medical Group hereunder do
not require, are not payment for and are not in any way contingent upon the
admission, referral or any other arrangement for the provision of any item or
service offered by the Management Company to any of the Medical Group's patients
in any medical facility or laboratory controlled, managed or operated by the
Management Company or to any other medical practice to which the Management
Company or its affiliates provides non-medical management services.


<PAGE>


     (d) The Medical Group and the Management Company acknowledge that certain
federal and state statutes severely restrict or prohibit the Management Company
from providing medical services. Accordingly, during the Term, the Management
Company represents and warrants that it shall not provide or otherwise engage in
services or activities which constitute the practice of medicine, as defined in
Applicable Law (as defined below), except in compliance therewith.

     (e) The Management Company shall not interfere with the exercise of
professional judgment by any Medical Personnel (as defined below) nor shall the
Management Company interfere with, control, direct or supervise any health care
provider in connection with the provision of Medical Services. The foregoing
sentence shall not preclude the Management Company from assisting the Medical
Group in the development of professional protocols and monitoring compliance
with policies and procedures that have been instituted in accordance with this
Agreement.

     (f) The Medical Group hereby designates and appoints the Management Company
to be the agent of the Medical Group during the Term to perform the following
duties and for those purposes incidental thereto, all of which shall be
performed in a manner reasonably acceptable to the Medical Group: (i) to bill
patients and third party payors in the Medical Group's name and on its behalf;
(ii) to collect accounts receivable resulting from such billing; (iii) to
receive payments and prepayments from the Medical Group's patients, Blue Cross
and Blue Shield organizations, insurance companies, health care plans, Medicare,
Medicaid, HMO's and any and all other third party payors; (iv) to take
possession of and deposit in the name of the Medical Group in accordance with
Section 1(g) (and/or in the name of any partner of the Medical Group or an
individual physician, if such payment is intended for purposes of payment of
such partner's or physician's bill) any notes, checks, money orders, insurance
payments, cash, cash equivalents and other instruments received in payment of
accounts receivable; and (v) to initiate, with the reasonable and timely consent
of the Medical Group, the institution of legal proceedings in the name of the
Medical Group to collect any accounts and monies owed to the Medical Group, to
enforce the rights of the Medical Group as a creditor under any contract or in
connection with the rendering of any service, and to contest adjustments and
denials by governmental agencies (or its fiscal intermediaries) as third-party
payors. The Management Company, in its capacity as agent pursuant to this
Section 1(f), shall not have any duties or responsibilities except those
expressly set forth in Sections 1(f)(i) through (v) above. From time to time at
the Management Company's request, the Medical Group shall make available to the
Management Company an authorized officer (the "Authorized Officer") of the
Medical Group to sign any letters, checks, instruments or other documents (the
"Documents") on behalf of the Medical Group that are necessary for the
Management Group to 


                                      -2-
<PAGE>

perform its duties as agent under this Section 1(f) and the Management Services.
If the Management Company notifies the Medical Group that the Authorized Officer
is not signing the Documents in a timely manner, the Management Company shall
not be liable for any failure to perform its duties as agent hereunder or
failure to perform the Management Services arising from the failure of the
Authorized Officer to sign the Documents in a timely manner.

     (g) The Management Company shall deposit in such bank (the "Medical Group
Bank") as the Medical Group designates, in an account in the Medical Group's
name (the "Medical Group's Account"), all monies collected by the Management
Company for or on behalf of the Medical Group in connection with the Medical
Group's provision of Medical Services. The Medical Group, on a weekly basis,
shall instruct the Medical Group Bank to transfer funds in the Medical Group's
Account necessary to pay the Management Fee (as defined in Schedule IV) (less
the amount necessary to avoid the payment of bank charges or fees relating to
the failure to maintain a minimum balance in the Medical Group's Account) to a
bank (the "Management Company Bank") designated by the Management Company, to an
account in the Management Company's name (the "Operating Account"). The
Management Company will disburse such monies from the Operating Account as
required pursuant to this Agreement. All interest earned on the Reimbursement
Fee on deposit in the Operating Account shall be for the account of the Medical
Group and all interest earned on the Billing Fee on deposit in the Operating
Account shall be for the account of the Management Company.

     SECTION 2. Term. The base term (the "Base Term") of this Agreement will be
for five years commencing on the date hereof (the "Effective Date") and will be
automatically extended for successive two-year renewal terms (each a "Renewal
Term" and together with the Base Term, the "Term") unless either party provides
written notice of termination at least 90 days but no more than 180 days prior
to the end of any such Renewal Term.

     SECTION 3. Management Services. (a) The Management Company shall be the
manager and administrator of the Management Services for the Medical Group. The
Management Company shall have no authority, directly or indirectly, to perform,
and shall not perform, any medical function. The Management Company may,
however, advise the Medical Group as to the relationship between its performance
of medical activities and the administrative and business functioning of its
practice.

     (b) The Management Company shall provide the Management Services and pay on
behalf of the Medical Group on a timely basis the costs and expenses (the 
"Actual Costs") described on Schedule II relating to the Management Services.
                             -----------

     (c) The Management Company shall not be liable to the Medical Group for
failure to perform any of the services required herein in the event of strikes,
lock-outs, calamities, acts of God, changes in any provision of laws, statutes,
ordinances, rules, regulations, permits, certificates, writs, decrees or orders
of any governmental authority ("Applicable Law"), changes in the reimbursement
rates payable for medical services by third party payors or other events over
which the Management Company has no control (each, a "Force Majeure Event") for
so long as such events continue; provided, that the Management Company continues
to perform such services during the continuance of a Force Majeure Event to the
full extent it is reasonably capable of doing so under the circumstances.

     (d) Nothing in this Agreement shall be construed to affect or limit in any
way the professional discretion of the Medical Group to select and use
facilities, equipment, computer hardware or software, furnishings, inventory and
supplies purchased by the Management Company in accordance with the terms of
this Agreement insofar as such selection or use constitutes or might constitute
the practice of medicine. THE MEDICAL GROUP ACKNOWLEDGES THAT THE MANAGEMENT
COMPANY MAKES NO WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, AS TO THE
SUITABILITY OR ADEQUACY OF ANY FACILITIES, EQUIPMENT, COMPUTER HARDWARE,
COMPUTER SOFTWARE, FURNISHINGS, INVENTORY OR SUPPLIES PROVIDED PURSUANT TO THIS
AGREEMENT FOR THE CONDUCT OF A MEDICAL PRACTICE OR FOR ANY OTHER PARTICULAR
PURPOSE, EXCEPT THAT THE MANAGEMENT COMPANY DOES REPRESENT AND WARRANT TO THE
MEDICAL GROUP THAT THE EQUIPMENT, COMPUTER HARDWARE AND COMPUTER SOFTWARE THAT
THE MANAGEMENT COMPANY SELECTS FOR USE BY THE MEDICAL GROUP SHALL BE SUITABLE
AND ADEQUATE FOR USE BY THE MEDICAL GROUP FOR SUCH INTENDED USES.

     SECTION 4. Joint Management Advisory Board. The parties shall establish a
joint management advisory board (the "JMAB") which shall be responsible for
developing management and administration policies for the overall operation of
the Medical Group. The JMAB shall initially consist of five members. The
Management Company shall designate two members of the JMAB reasonably acceptable
to the Medical Group. The Medical Group shall designate, in its sole discretion,
three members (the "Medical Group Representatives") of the JMAB which Medical
Group Representatives shall each be duly licensed and registered Physician
Partners (as defined below). The Medical Group shall at any and all times
maintain a simple majority of the members of the JMAB. All actions taken by, or
decisions of, the JMAB shall require the vote of a majority of the members of
the JMAB, including at least two of the Medical Group Representatives.

     SECTION 5. Obligations of the Medical Group. (a) The Medical Group shall
ensure that each Medical Personnel providing medical care to patients of the
Medical Group is duly licensed by and registered with the State of New York and
any other state in which such Medical Personnel may provide medical care.

     (b) The Medical Group shall have control of and responsibility for the
compensation of its Medical Personnel, although, at the request of the Medical
Group, the Management Company shall consult with the Medical Group regarding
such matters. The Medical Group shall be responsible for the payment of salaries
and wages, payroll taxes, benefits and all other taxes and charges now or
hereafter applicable to such Medical Personnel.

     (c) The Medical Group and its Medical Personnel shall be solely responsible
for the cost of membership in professional associations and continuing

     (d) The Medical Group shall obtain and maintain professional liability
insurance for the Medical Group and its Medical Personnel and shall notify the

Medical Personnel within five business days of the Medical Group receiving
notice of such change.

     (e) The Medical Group shall be solely responsible for all costs, fees and
expenses related to the items and services listed on Schedule III.

     (f) The Medical Group shall not be liable to the Management Company for
failure to perform any of the obligations contained herein except for the
Medical Group's obligations pursuant to Sections 1(g), 6, 7(b), 7(d), 9, 10, 12,
13, 15 and 22.

     SECTION 6. Fees. (a) In consideration of the Management Services rendered
by the Management Company, the Medical Group shall pay to the Management Company
in arrears on the tenth business day of each month the fees set forth on
Schedule IV.

     (b) The Medical Group shall pay its obligations to the Management Company
in a prompt and timely manner.

     SECTION 7. Insurance and Indemnity. (a) The Medical Group shall maintain
comprehensive professional liability insurance at least sufficient to comply
with any regulatory requirement and/or contractual requirement to which each
Medical Personnel or the Medical Group may be subject and a separate limit for
the Medical Group. If excess coverage is available to the Physician Partners or
Physician Employees through their affiliate hospitals at no charge (referred to
as "Section 17 coverage"), they shall obtain and maintain such excess coverage
at all times during the Term. The Medical Group shall be responsible for all
liabilities in excess of the limits of such policies.

     (b) The Medical Group shall indemnify, hold harmless and defend the
Management Company, its officers, 



                                      -5-

directors, shareholders, employees, agents and independent contractors from and
against any and all liabilities, losses, damages, claims, causes of action and
expenses (including reasonable attorneys' fees and expenses), whether or not
covered by insurance, caused or asserted to have been caused, directly or
indirectly, by or as a result of (i) any acts or omissions of the Medical Group,
its members or employees or (ii) any breach of or failure to perform any
obligation under Sections 1(g), 6, 7(b), 7(d), 9, 10, 12, 13, 15 and/or 22 of
this Agreement by the Medical Group and/or its partners, agents, employees
and/or subcontractors (other than the Management Company) during the Term. In
addition, the Medical Group shall reimburse the Management Company for any legal
expenses incurred by reason of the Management Company or any affiliate thereof
being named as a party to any suit or claim based upon Medical Services provided
by the Medical Group, its members or employees, including, without limitation,
any suit or claim arising from, relating to or in connection with the Medical
Group's failure to perform its obligations set forth in Section 7(a).

     (c) The Management Company shall indemnify, hold harmless and defend the
Medical Group, its officers, directors, partners, employees, agents and
independent contractors from and against any and all liabilities, losses,
damages, claims, causes of action and expenses (including reasonable attorneys'
fees and expenses), whether or not covered by insurance, caused or asserted to
have been caused, directly or indirectly, by or as a result of (i) the
performance of Management Services, (ii) any other acts or omissions or (iii)
any breach of or failure to perform any obligation under this Agreement by the
Management Company and/or its partners, agents, employees and/or subcontractors
(other than the Medical Group). In addition, the Management Company shall
reimburse the Medical Group for any legal expenses incurred by reason of the
Medical Group or any affiliate thereof being named as a party to any suit or
claim based upon the Management Services provided by the Management Company, its
members or employees.

     (d) (i) In the event any action, suit or proceeding is brought by a third
party against the Medical Group or the Management Company (an "Indemnified
Person"), with respect to which the Medical Group or the Management Company (an
"Indemnifying Person") may have liability under this Section 7, the action, suit
or proceeding shall, upon the written agreement of the Indemnifying Person that
it is obligated with respect to such action, suit or proceeding, be defended
(including all proceedings on appeal or for review which counsel for the
defendant shall deem appropriate) and, unless otherwise provided below,
controlled by such Indemnifying Person. The Indemnified Person shall have the
right to employ its or their own counsel in any such case, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Person,
unless (A) the employment of such counsel shall have been authorized in writing
by the Indemnifying Person in connection with the defense of such 


                                      -6-
<PAGE>

action, suit or proceeding, (B) the Indemnifying Person shall fail actively and
diligently to defend such action, suit or proceeding, (C) the Indemnified Person
shall have reasonably concluded that such action, suit or proceeding involves to
a significant extent matters beyond the scope of the indemnity agreement
contained in this Section 7 or (D) the Indemnified Person shall have reasonably
concluded that there may be one or more legal or equitable defenses available to
the Indemnified Person which are different from or addition to those available
to the Indemnifying Person, in any of which events the Indemnifying Person shall
not have the right to direct the defense of such action, suit or proceeding on
behalf of the Indemnified Person; provided, however, that: (I) the portion of
any fees and expenses of such counsel involving matters beyond the scope of the
indemnity agreement contained in this Section 7 shall be borne by the
Indemnified Person and (II) the Indemnified Person shall not make any settlement
of any action, suit or proceeding without the written consent of the
Indemnifying Person, which consent shall not be unreasonably withheld. The
Indemnified Person shall be kept reasonably informed of such action, suit or
proceeding at all stages thereof whether or not they are so represented. The
Indemnifying Person shall make available to the Indemnified Person and their
attorneys and accountants al books and records of the Indemnifying Person
relating to such action, suit or proceeding and the parties hereto agree to
render to each other such assistance as they may reasonably require of each
other in order to ensure the proper and adequate defense of such action suit or
proceeding.

     (ii) The Indemnifying Person shall not make any settlement of any action,
suit or proceeding without the written consent of the Indemnified Person, which
consent shall not be unreasonably withheld; provided, however, that in the event
the Indemnified Person refuses to consent to a settlement acceptable to the
Indemnifying Person which is capable of settlement by the payment of money only
and the Indemnifying Person shall demonstrate to the reasonable satisfaction of
the Indemnified Person their ability to pay such amount, the Indemnifying Person
may pay the amount of the proposed settlement to the Indemnified Person and
shall thereupon be released from any further liability with respect to such
action, suit or proceeding.

     SECTION 8. Termination. (a) This agreement may be terminated by mutual
written consent of the parties.

     (b) The Medical Group may terminate this Agreement effective immediately by
giving written notice to the Management Company (i) in the event the Management
Company materially defaults in the performance of any duty or obligation imposed
on it by this Agreement and such default shall continue for a period of 20 days
after written notice thereof has been given to the Management Company by the
Medical Group, (ii) in the event the Management Company materially defaults in
the performance of any 


                                      -7-
<PAGE>

duty or obligation imposed on it by the Sublicense Agreement, dated the date
hereof (the "Sublicense Agreement"), between the Management Company and the
Medical Group, and such default shall continue for a period of 30 days after
written notice thereof has been given to the Management Company by the Medical
Group, (iii) in the event the Management Company files a petition in bankruptcy
or makes an assignment for the benefit of creditors or otherwise seeks relief
from creditors under a federal or state bankruptcy, insolvency, reorganization
or moratorium statute, or the Management Company is the subject of an
involuntary petition in bankruptcy which is not set aside within 90 days after
its filing or (iv) pursuant to Section 22.

     (c) The Medical Group may terminate this Agreement upon 90 days' prior
written notice to the Management Company if (i) in any calendar year during the
Term commencing with calendar year 1998, the Medical Group's net collected
revenues per physician (determined by dividing the Medical Group's net collected
revenues during such calendar year by the weighted average number of physicians
in the Medical Group during the calendar year under consideration) is less than
80% of the Medical Group's net collected revenues per physician (determined on
the same basis) in calendar year 1996, unless such reduction results from a
Force Majeure Event or an action or series of actions within the reasonable
control of the Medical Group or (ii) at any time commencing with the first
calendar quarter in calendar year 1998, the Medical Group's Actual Costs per
physician during any calendar quarter (determined by dividing the Medical
Group's Actual Cost by the weighted average number of physicians in the Medical
Group during the calendar quarter under consideration) exceed by more than 10%
the Medical Group's average quarterly Actual Costs per physician during calendar
year 1997 (adjusted for any increase in the Consumer Price Index for Medical
Services for the Standard Metropolitan Statistical Area including New York City
from and after June 30, 1998) (the "Average Quarterly Actual Costs") unless such
excess results from a Force Majeure Event or additional or increased expenses
approved in advance by the Medical Group; provided, however that in the event
that the Medical Group expands to include more noninterventional cardiologist
physicians or other generalist or specialist physicians, the Medical Group and
the Management Company shall meet within 60 days thereafter and mutually agree
upon a different percentage in clause (i) above and a higher percentage in
clause (ii) above. Notwithstanding the foregoing, the Medical Group shall not
have the right to terminate this Agreement pursuant to clause (ii) of the
immediately preceding sentence if the Management Company agrees to a reduction
in the Management Fee in respect of such calendar quarter in an amount necessary
to reduce such excess over the Average Quarterly Actual Costs to 10%, or such
higher percentage as mutually agreed upon by the parties, or less.

     (d) The Management Company may terminate this Agreement effective
immediately by giving written notice to the 


                                      -8-
<PAGE>

Medical Group (i) in the event the Medical Group shall materially default in the
performance of any duty or obligation imposed upon it by this Agreement and such
default shall continue for a period of 20 days after written notice thereof has
been given to the Medical Group by the Management Company, (ii) in the event the
Medical Group shall materially default in the performance of any duty or
obligation imposed upon it by the Sublicense Agreement and such default shall
continue for a period of 30 days after written notice thereof has been given to
the Medical Group by the Management Company, (iii) in the event the Medical
Group files a petition in bankruptcy or makes an assignment for the benefit of
creditors or otherwise seeks relief from creditors under a federal or state
bankruptcy, insolvency, reorganization or moratorium statute, or the Medical
Group is the subject of an involuntary petition in bankruptcy which is not set
aside within 90 days after its filing or (iv) pursuant to Section 22.

     (e) The Management Company may terminate this Agreement upon 90 days' prior
written notice to the Medical Group if in any calendar year during the Term
commencing with calendar year 1998, the Medical Group's net collected revenues
per physician (determined by dividing the Medical Group's net collected revenues
during such calendar year by the weighted average number of physicians in the
Medical Group during the calendar year under consideration) is less than 80% of
the Medical Group's net collected revenues per physician (determined on the same
basis) in calendar year 1996 unless such reduction results from a Force Majeure
Event or an action or series of actions within the reasonable control of the
Management Company; provided, however that in the event that the Medical Group
expands to include more non-interventional cardiologist physicians or other
generalist or specialist physicians, the Medical Group and the Management
Company shall meet within 60 days thereafter and mutually agree upon a different
percentage in this Section 8(e).

     (f) If the Management Company terminates this Agreement pursuant to Section
8(d), the Medical Group's right to participate in the Rollup (as defined in
Section 3 of the Stockholders' Agreement, dated the date hereof, among the
Management Company and the Stockholders listed on Schedule I thereto) shall
immediately terminate.

     SECTION 9. Non-Disclosure of Confidential Information. (a) Neither the
Medical Group, its Medical Personnel, other employees, consultants,
representatives or agents (the "Medical Group Disclosees") nor the Management
Company, its employees, consultants, representatives or agents (the "Management
Company Disclosees") shall, at any time after the execution and delivery hereof,
directly or indirectly disclose any confidential or proprietary information
relating to the other party hereto to any person, firm, corporation, association
or other entity, nor shall the Medical Group Disclosees or the Management Group
Disclosees make use of any of such confidential or proprietary information 


                                      -9-
<PAGE>

for its or their own purposes or for the benefit of any person, firm,
corporation or other entity except the other party hereto or any subsidiary or
affiliate thereof. The foregoing obligation shall not apply to any information
which the Medical Group Disclosees or the Management Company Disclosees, as the
case may be, can establish to have (i) become publicly known without breach of
this Agreement by it or them, (ii) been known to the Medical Group Disclosees,
or any of them, prior to disclosure by the Management Company or (iii) to have
been given to the Medical Group by a third party who is not obligated to
maintain the confidentiality of such information.

     (b) The term "confidential or proprietary information" shall mean all
information which is known to the Medical Group Disclosees or the Management
Company Disclosees, as the case may be, which relates to this Agreement or
matters such as patient medical records and charts, trade secrets, books and
records, supplies, pricing and cost information, marketing plans, strategies and
forecasts. Nothing contained herein shall prevent the Medical Group Disclosees
or the Management Company Disclosees, as the case may be, from furnishing
confidential or proprietary information pursuant to a direct order of a court or
governmental authority of competent jurisdiction. In the event that the Medical
Group Disclosees or the Management Company Disclosees are requested or become
legally compelled (by oral questions, interrogatories, request for information
or documents, subpoena, civil investigative demand or similar process) to
disclose any confidential or proprietary information, the Medical Group
Disclosees or the Management Company Disclosees, as the case may be, shall
provide the other party hereto with prompt written notice thereof so that the
other party hereto may seek a protective order, confidential treatment of such
confidential or proprietary information or other appropriate remedy.

     SECTION 10. Restrictive Covenants. The Medical Group acknowledges and
recognizes the highly competitive nature of the business of the Management
Company and that goodwill is an essential asset of the Management Company.
Accordingly, during the Term, the Medical Group shall not (i) directly or
indirectly engage in any Competitive Business (as defined below), whether such
engagement shall be as an employer, owner, consultant, partner or other
participant in any Competitive Business, (ii) assist others in engaging in any
Competitive Business in the manner described in the foregoing clause (i), (iii)
employ or otherwise induce employees of the Management Company to terminate
their employment with the Management Company or engage in any Competitive
Business or (iv) induce customers or vendors of the Management Company to alter
or terminate their business relationship with the Management Company. As used
herein, the term "Competitive Business" shall mean any business which, directly
or indirectly, competes with the Management Company in the provision of
management services to professional medical organizations; provided, however,
that the provisions of this Section 10 will not be deemed breached merely
because the Medical 


                                      -10-
<PAGE>

Group owns not more than 2% of the outstanding equity securities of an entity
if, at the time of the acquisition of such equity securities, such securities
are listed on a national securities exchange, the NASDAQ National Market System,
the NASDAQ SmallCap System or are regularly traded in the over-the-counter
market.

     SECTION 11. Inadequate Remedy at Law. The Management Company and the
Medical Group acknowledge and agree that since a remedy at law for any breach or
attempted breach of the provisions of Sections 9 or 10 shall be inadequate
either party shall be entitled to specific performance and injunctive or other
equitable relief in case of any such breach or attempted breach, in addition to
any remedies available at law. If any provision of Section 10 relating to the
restrictive period and/or the scope of activity restricted shall be declared by
a court of competent jurisdiction to exceed the maximum time period or scope of
activity restricted such court deems reasonable and enforceable under Applicable
Law, the time period and/or scope of activity restricted held to be reasonable
and enforceable by such court shall thereafter be the restrictive period and/or
scope of activity restricted applicable to the restrictive covenant provisions
in Section 10. The invalidity or non-enforceability of Sections 9 or 10 in any
respect shall not affect the validity or enforceability of the remainder of
Sections 9 or 10 or of any other provisions of this Agreement.

     SECTION 12. Assignment. The Management Company shall have the right to
assign its rights and delegate its duties hereunder to any affiliated entity of
the Management Company (provided that the Management Company shall continue to
remain responsible for the performance of its obligations under this Agreement)
and the Medical Group shall have the right to assign its rights and delegate its
duties hereunder to a successor entity. Except as set forth in the preceding
sentence, neither the Management Company nor the Medical Group shall assign its
rights hereunder without the prior written consent of the other party.

     SECTION 13. Notices. All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed sufficient if
personally delivered, sent by nationally-recognized overnight courier, sent by
facsimile or by registered or certified mail, return receipt requested and

shall clearly set forth the factual and legal basis for such award or decision.
Judgment on the award or decision rendered by the arbitrator shall be
non-appealable and enforceable in any court having jurisdiction thereof. The
costs of the arbitration, including administrative, legal and arbitrator fees,
shall be borne by the losing party, or according to the discretion of the
arbitrator if the parties disagree as to which party is the losing party under
the award or decision.

waived, discharged or terminated except by a written agreement signed by each of
the parties hereto.

                                      -13-
<PAGE>

               -----------------
rendered by the Management Company, the Medical Group shall pay to the
Management Company on the fourth business day of each week during the Term a
reimbursement fee (the "Reimbursement Fee") equal to the costs and expenses set
forth on Schedule II actually incurred by the Medical Group during the preceding
         -----------
week.

          2.   Billing Fee; Management Fee.  In consideration of the billing and

collection services rendered by the Management Company, the Medical Group shall
pay to the management Company in arrears on the tenth business day of each month
during the Term a billing fee (the "Billing Fee" and together with the
Reimbursement Fee collectively, the "Management Fee") equal to [     ]* of the

          3.  Adjustments.  (a)  The Management Fee payable on July 1, 1997 and
              -----------
each January 1 and July 1 thereafter during the Term shall be adjusted by andy
Savings (as defined below) realized during the six-month period immediately
preceding such date (each, a "Period").

               (b)  The Savings shall be an amount equal (i) an amount equal to
(A) the Base Burden Percentage (as defined below) multiplied by (B) the
                                                  ----------

Group to the Management Company from the date hereof through December 31, 1996
by (ii) the aggregate collected revenues of the Medical Group from the date

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

agreed upon by the parties on a contract-by-contract basis.  Upon the request of

security to be provided by the Management Company to the Medical Group to secure
the Management Company's reimbursement obligations to the Medical Group in
connection with a risk-based contract entered into by the Medical Group.

                            ONCOLOGY NETWORK ADDENDUM

          THIS ADDENDUM dated as of 6/30, 1994, to the Administrative Services

               Emory Oncology Network participating physicians ("Network

          1.3  Generate standard provider reports for the Emory Oncology Network

          1.4  Create and maintain Emory Oncology Network credentialing files,
               generate notices to Network Participants informing them of
               upcoming re-credentialing dates, and support the Emory Oncology

               generated under managed care contracts, organizing subscriber

               Oncology Network.

               require to review or modify managed care contracts.

          1.10 Disburse funds from the Emory Oncology Network bank account to
               Network Participants according to Emory Oncology Network
               procedures or, alternatively, report financial information to the
               Emory Oncology Network for fund disbursement to Network
               Participants by the Emory Oncology Network.

     2. Agreements and Responsibilities of the Emory Oncology Network. In
addition to Emory's further obligations hereunder, Emory agrees as follows:

          2.1  The Emory Oncology Network shall cause each Network Participant
               to submit claims to USHC or its designee according to the
               procedures established in the Emory Oncology Network's
               administrative manual. The Emory Oncology Network shall designate
               a person to serve as a liaison from the Emory Oncology Network to
               USHC for resolution of claims processing issues and shall cause
               each Network Participant to designate a liaison for similar
               purposes from his or her practice to USHC.

          2.2  The Emory Oncology Network shall comply and shall cause each of
               its Network Participants and their respective practices to comply
               with all legal and regulatory requirements relating to the
               furnishing of medical services to the public, including, but not
               limited to, obtaining payment of or reimbursement for such
               medical services including compliance with any requirements
               applicable to networks. The Emory Oncology Network shall obtain
               and maintain, and shall cause each of its Network Participants
               and their respective practices to obtain and maintain, in effect,
               all permits, licenses, and governmental or board approvals or
               notices which may be necessary for those purposes. The Emory
               Oncology Network shall obtain and maintain general and
               professional liability insurance in amounts acceptable to managed
               care payors and shall provide evidence to USHC of such coverage
               upon request. The Emory Oncology Network represents and warrants
               that, on or before the effective date of this Agreement, it will
               have received all consents and approvals required and given all
               notices necessary to enter into this Agreement.


                                      -2-
<PAGE>


          2.3  The Emory Oncology Network shall give written notice within ten
               (10) days to USHC of any legal, governmental, or other action
               initiated or consummated against the Emory Oncology Network or a
               Network Participant, which could impair the ability of the Emory
               Oncology Network or such Network Participant to perform the
               medical service required under managed care contracts or to
               obtain payment of or reimbursement for such services.

          2.4  USHC shall have no control over the practice of medical services
               provided by or arranged for by the Emory Oncology Network or any
               Network Participant or their personnel. The Emory Oncology
               Network shall retain sole control of the credentialing and
               utilization and quality management of the Emory Oncology Network
               and Network Participants. Nothing contained herein shall grant
               USHC or any party performing credentialing, utilization, or
               quality management support services the right to govern the level
               of care of a subscriber or beneficiary or to participate in any
               quality decisions affecting a Network Participant. While USHC may
               assist in assembling credentialing, utilization, and quality data
               in connection with managed care contracts or for the Emory
               Oncology Network, USHC shall have no responsibility for any
               credentialing, quality, or utilization management decisions. USHC
               shall have no responsibility for any costs or expenses associated
               with the operations of the Emory Oncology Network or those of any
               Network Participant. The Medical Director of the Emory Oncology
               Network shall serve as the Emory Oncology Network's liaison to
               USHC and shall attend USHC meetings upon request. The Emory
               Oncology Network shall use its best efforts to work with USHC in
               resolving administrative disputes.

          2.5  USHC may provide data and information regarding the Emory
               Oncology Network to independent contractors under agreement with
               USHC to fulfill USHC's obligations hereunder, provided that USHC
               shall insure that such independent contractors shall be obligated
               to maintain confidentiality of such data and information in
               accordance with the confidentially obligations imposed on USHC in
               Paragraph 8 of the Administrative Services Base Agreement.

          2.6  The Emory Oncology Network shall maintain and shall cause each of
               its Network Participants and their respective personnel to
               maintain records and procedures as may be required to account
               accurately for all services provided which are the subject of
               this Agreement and the managed care contracts. Such records shall
               be kept in accordance with generally accepted accounting
               principles 


                                      -3-
<PAGE>


               and recognized standards of professional medical practice and
               immediately available to USHC. The Emory Oncology Network shall
               provide and shall cause each of its Network Participants to
               provide to USHC all information necessary for it to fulfill its
               obligations under Paragraph 1 in a timely, accurate, and orderly
               manner. The Emory Oncology Network acknowledges that certain of
               USHC's obligations are conditioned upon its receipt of
               information from the Emory Oncology Network and, therefore, any
               failure of USHC to perform its obligations hereunder attributable
               to the failure of the Emory Oncology Network to provide such
               information shall not be considered a breach by USHC of this
               Agreement.

          2.7  USHC shall have the right of first refusal for administrative
               services for any Oncology Network which Emory proposes.

     3. Exclusivity.  During the term of this Addendum, and in a territory
described as Metropolitan Atlanta, Georgia, USHC shall not provide services
substantially similar to the Administrative Services to any other oncology
network, including both medical oncology and radiation oncology. However, such
exclusivity shall cease upon notice of termination.

     4. Compensation.

        For Administrative Services, USHC shall be compensated in an amount 
equal to [    ]* of the total revenue received by the Emory Oncology Network.
Payment shall be made by the tenth day of each month for revenue received in the
prior month.  Payments past due shall accumulate interest in an amount equal to
one percent (1%) per month commencing as of the date the payment becomes due.

     5. Term.

          5.1  The term of this Addendum shall run concurrently with the term of
               the Initial Payor Agreement, all Additional Payor Agreements, and
               any renewals thereof. The term of this Addendum shall terminate
               upon termination of the last payor agreement for which USHC
               provides Administrative Services to the Network under this
               Addendum.

          5.2  Notwithstanding Section 5.1, Emory has the right to terminate
               this Addendum for cause due to inadequate performance by USHC if
               USHC's performance is unacceptable to Emory and such inadequate
               performance is not remedied within thirty (30) days after notice
               is given by Emory to USHC of the inadequate performance.


* Omitted pursuant to Rule 406 promulgated under the Securities Act of 1933, as
amended.


                                      -4-
<PAGE>


          5.3  Notwithstanding Section 5.1, or anything to the contrary
               elsewhere, this Addendum may be terminated by either party for
               any reason, without cause, on one hundred eighty (180) days
               notice. However, any Payor Agreement that is listed on Exhibit
               "B" may only be terminated for cause pursuant to Section 5.2.

     6. Limitation of Liability. USHC's obligations to Emory are limited to the
agreements expressly set forth in this Addendum and the Administrative Services
Base Agreement described in Paragraph 8, below. The parties agree and
acknowledge that, without limitation, USHC shall have no responsibility for the
following as related to the Emory Oncology Network; utilization review; quality
assurance; credentialing of Network Participants; implementation of standards of
care; and, all other management decisions related to operations of the Emory
Oncology Network. The Emory Oncology Network shall provide or cause others to
provide to USHC accurate and complete patient and procedure charge and other
information in a timely and orderly manner. USHC is not obligated to verify
independently any information provided to it by the Emory Oncology Network or a
Network Participant in connection with performance of USHC's duties hereunder.
THEREFORE, USHC DOES NOT MAKE AND HAS NOT MADE, AND HEREBY DISCLAIMS, ANY AND
ALL WARRANTIES INCLUDING, WITHOUT LIMITATION, ANY EXPRESS, IMPLIED, OR STATUTORY
WARRANTIES, WITH RESPECT TO THE ACCURACY OR COMPLETENESS OF ANY CLAIMS, REPORTS,
OR OTHER INFORMATION OR DOCUMENTATION BASED UPON BILLING OR OTHER INFORMATION
PROVIDED TO USHC BY THE EMORY NETWORK OR A NETWORK PARTICIPANT. EMORY
ACKNOWLEDGES THAT USHC IS NOT A GUARANTOR OF PAYMENTS.

     7. Indemnification. Emory agrees to indemnify USHC for, and hold USHC
harmless for all time from and against, any and all claims, damages,
liabilities, charges, and expenses of any nature, including, without limitation,
attorneys' fees, regardless of whether such attorneys' fees are incurred in
connection with litigation, that USHC may incur in the defense of any claims,
demands, actions, lawsuits, or proceedings of any kind brought against USHC
arising from the following as related to the Emory Oncology Network: provision
of medical services by Network Participants; credentialing of physician
participants; utilization of medical services by physician participants;
development and implementation of standards of care; and payments from managed
care payors and patients.

     8. Entire Agreement. This Addendum and the Administrative Services Base
Agreement constitute the entire agreement of the parties for provision of
Administrative Services to the Emory Oncology Network, and all prior
representations, whether written or oral, are merged herein. This Addendum may
be modified or altered only by written instrument signed by both parties. If
there are any ambiguities or conflicts between the terms and conditions of this
Addendum and the terms and conditions of the Administrative Services Base
Agreements the terms and conditions of this Addendum 


                                      -5-

shall govern.
