ITEM 1. BUSINESS

OVERVIEW

    CareScience, Inc. is a provider of online care management services. Our
mission is to transform the quality and efficiency of care delivery by providing
innovative clinical information technology to the health care industry. We
market our products and services to hospitals, health systems and pharmaceutical
and biotechnology manufacturers, and support more than 150 customers in 40
states and in Europe.

    We work with health care providers to manage clinical processes surrounding
the point of care so that fundamental reductions in errors and operating costs
can be achieved. Our products collect, share, store and analyze clinical data
generated by more than 100 widely used health information systems. Our products
allow customers to apply this data to the management of care, including quality
monitoring, practice improvement, credentialing, profiling, error tracking, case
management and clinical guidelines. We provide consulting services to health
care providers that support strategic planning and clinical operations, with a
special emphasis on mentoring physicians and other clinical leaders in
operational and executive roles.

    For the pharmaceutical and biotechnology industry, we provide tools and
services that shorten the drug development cycle and improve development yield.
Our offerings include a suite of Internet-based data analysis and workflow
management tools, consulting services, customized research and strategic
development support. These tools and services are aimed at the specialized drug
development needs of pharmaceutical industry clinicians, product managers,
market strategists, health economists, and outcomes researchers.

    We have pioneered and commercialized numerous clinical information
technologies. We have developed one of the nation's first online quality
measurement and management tools, one of the first clinically based outcome risk
assessment algorithms, one of the first health care application service
providers, and, most recently, the first peer-to-peer clinical data sharing
technology. We have developed these tools in collaboration with leading public
organizations, including the Wharton School of Business at the University of
Pennsylvania, the National Library of Medicine, Los Alamos National Laboratory
and The California HealthCare Foundation.

    CareScience was incorporated in 1992 with the purpose of commercializing
intellectual property that was developed at the University of Pennsylvania
School of Medicine and The Wharton School of Business. In 1993, we exclusively
licensed the intellectual property underlying our core technology in a 30-year
agreement with the University of Pennsylvania. In 1996, we launched our first
Internet-based commercial product based on this proprietary technology under our
Care Management System-TM- (formerly called CaduCIS) product line. In 1999, we
launched our Care Data Exchange-TM-, and Technology Assessment Tools-TM-, as
well as our Lifecycle Decision System-TM- product line, which is aimed at the
pharmaceutical and biotechnology industries. To date, we have signed more than
50 contracts covering more than 135 hospitals, health systems and pharmaceutical
companies. On March 7, 2000, we changed our name from Care Management Science
Corporation to CareScience, Inc.

INDUSTRY BACKGROUND

CLINICAL COSTS ARE LARGE AND GROWING

    According to the Health Care Financing Administration, or HCFA, annual
health care spending in the United States exceeds $1.2 trillion, or 14% of the
country's gross domestic product, and is expected to grow to $2.2 trillion by
2008. Current online efforts are primarily seeking to change administrative and
financial processes, reduce systems costs, improve cash flow or speed billing
and purchasing. Even

                                       1

if successful, these efforts do not address the significant majority of health
care spending that results from the cost of clinical diagnosis and treatment.
These costs arise from the process of medical decision-making, treatment choice
and therapeutic efficacy, and comprise the largest portion of spending in the
health care industry. Furthermore, we estimate that hospitals and pharmaceutical
companies spend more than $25 billion annually to manage treatment decisions and
attempt to control clinical costs. As inefficiencies within the health care
system consume enormous resources, as well as pose medical risks to consumers,
constituents across the health care industry are seeking cost-effective
information and tools to improve the quality and efficiency of care delivery.

CONCERNS ABOUT CLINICAL QUALITY AND MEDICAL ERRORS ARE INCREASING

    The delivery of clinical care usually involves complex procedures, multiple
treatments and subjective judgments. Even appropriate clinical decisions are
often difficult to implement and analyze because of uncontrolled operational
systems. Hospitals and health plans have been seeking to gain control of and
measure clinical processes to increase accountability and improve care.

    Problems with quality in the health care industry have recently gained
attention because of advances in the ability to measure medical errors and
complications and increasing concern about clinical care among policy-makers and
the public. In addition to being the eighth-leading cause of death in the United
States according to the Institute of Medicine's 1999 report "To Err is Human,"
medical errors add substantial costs to and drive consumer dissatisfaction with
the delivery of care. Medical errors and complications result in unnecessary
events including emergency room visits, hospitalizations, specialist referrals
and laboratory studies, all of which are used to evaluate the errors and manage
the consequences they create. We believe that many of the current efforts to
reduce administrative waste and improve financial performance do not address the
processes that result in clinical inefficiencies. Health care delivery systems,
physicians, health plans, the government and employers are seeking information
regarding clinical quality and medical errors as well as tools to enhance
clinical efficiency. Recently, the Institute of Medicine's 2001 report "Crossing
the Quality Chasm: A New Health System for the 21stCentury" called for
widespread adoption of technology and managerial methods to substantially reduce
the occurrence of medical errors and complications.

HEALTH CARE CONSTITUENTS REMAIN HIGHLY FRAGMENTED

    Health care is delivered locally in hundreds of thousands of locations
through a complex and fragmented mix of constituents, including:

    - hospitals, health systems, medical practice groups and other provider
      organizations;

    - physicians in solo or small-group practices;

    - payors, such as insurance companies, managed care organizations, Medicare,
      Medicaid and employers; and

    - suppliers, such as clinical laboratories, pharmaceutical companies and
      other groups that provide tests, drugs, x-rays and other medical supplies
      and services.

    Historically, many of these organizations have tried to improve efficiency,
accountability and clinical-process control by horizontally or vertically
integrating with other constituents. For example, hospitals acquired physician
practices in order to create integrated delivery systems. These efforts have
largely been abandoned because these systems were unable to integrate clinical
services and establish common goals. Additionally, these efforts highlighted the
importance of being able to share clinical, operational and administrative
information.

                                       2

TECHNOLOGICAL FRAGMENTATION LEADS TO INEFFICIENT USE OF CLINICAL DATA

    In order to efficiently deliver care, information must flow within and
between health care constituents. For example, to diagnose and treat a patient
properly, physicians need access to clinical information such as medical history
data, laboratory results, x-rays and prescriptions from various hospitals,
laboratories and other providers. Health care constituents have not historically
coordinated their information technology investments due to:

    - the large number of constituents;

    - the complexity of health care encounters and transactions;

    - the cost of deploying technology; and

    - pervasive concerns about confidentiality of patient information.

    This has resulted in the current technology infrastructure in health care
being characterized by numerous incompatible and proprietary mainframe and
client/server systems that store information in isolated databases using
non-standardized formats. Thus, providers must typically request information by
phone, fax or patient survey and those requests are frequently delayed due to
disparate paper-based systems maintained by most constituents. Furthermore, the
lack of timely access to accurate clinical information, particularly in an
urgent-care situation, may lead to poor clinical outcomes and excess costs
through:

    - inaccurate diagnoses;

    - redundant tests; and

    - enhanced potential for medical errors and clinical complications.

    As a result of geographic, organizational and technological fragmentation,
current information exchange is often incomplete or redundant, thus creating the
need for a comprehensive technology solution.

THE GROWTH OF THE INTERNET IS IMPACTING HEALTH CARE

    The Internet has emerged as the fastest growing communication medium in
history. International Data Corporation, an independent research firm, estimates
that the total number of Internet users worldwide will grow from 142 million at
the end of 1998 to 502 million by the end of 2003. The Internet is currently
being used to speed and streamline a variety of business transactions. The
Internet's open architecture, platform and location independence, scalability
and growing acceptance make it an increasingly important medium for the
information-intensive and highly transactional health care industry. We believe
that many existing Internet products do not provide tools to monitor the care
delivery process or improve clinical efficiency. Additional improvements in the
ability to search, store, structure, integrate and filter vast amounts of
disparate data and to dynamically analyze, customize and display information in
contexts relevant to particular users will further increase the usefulness of
Internet-based applications to the health care market.

PHARMACEUTICAL AND BIOTECHNOLOGY COMPANIES NEED BETTER INFORMATION CLOSER TO THE
POINT OF DECISION

    According to a 1994 study by Duke University, seven out of ten
commercialized pharmaceutical products fail to recoup their development costs.
In order to reduce the failures of the drug development and commercialization
process better decisions about discovery, research and marketing need to be
made. We believe that pharmaceutical and biotechnology companies need access to
better clinical information closer to the point of their drug development
decisions. Moreover, additional improvements in the ability to analyze and apply
information in contexts relevant to pharmaceutical

                                       3

and biotechnology users will further increase the usefulness of Internet-based
applications to the health care market.

THE CARESCIENCE SOLUTION

    We are a clinical knowledge company with a mission to inform health care
professionals at the point of decision--for better quality at the point of care.
For providers, we offer care management solutions, data sharing technologies,
technology assessment tools and consulting services. For pharmaceutical and
biotechnology companies, we specialize in data analysis, decision support,
extranet development and consulting. For our partners, we offer programs that
help promote technology standards and a secure environment for data sharing.

    Our range of Internet-based tools for care management, clinical analysis and
data exchange are designed with a single goal--to improve the quality and
efficiency of health care delivery. They help health care professionals:

    ACCESS COMPREHENSIVE PATIENT DATA MORE EFFICIENTLY.  Our technologies
provide information to influence diagnostic and treatment decisions by enabling
secure information sharing among authorized health care constituents. We believe
that health care providers who can access clinical information immediately and
securely at the point of care will become the standard-bearers of informed care.
Since much information is not currently available at the point of care, we are
developing an Internet-based peer-to-peer technology that allows health care
organizations to share patient information across locations--allowing providers
direct access to patient data when and where it is most needed--at the point of
care. This peer-to-peer technology will provide secure, real-time Internet
access to clinical results, patient demographics, medical records and other
critical data from the original source.

    ANALYZE COMPREHENSIVE PATIENT DATA MORE EFFICIENTLY.  Our proprietary
scientific methodologies were developed at the University of Pennsylvania School
of Medicine and The Wharton School. Our algorithms allow us to normalize
clinical information across thousands of parameters using sophisticated
statistical analysis and, in conjunction with our online analytic processing
technology, provide retrospective as well as predictive evaluation of clinical
performance. Unlike benchmarking, which compares performance to designed
protocols or averages of broad populations across a limited number of criteria,
our algorithms allow users to understand the underlying basis of their clinical
performance. For example, when a patient experiences a clinical complication, we
can determine the likelihood that the complication was attributable to the
patient's condition, the physician's decisions or the hospital's operations, and
for any of these, which specific factors contributed to the complication. We
believe our products provide health care constituents with the most
comprehensive, robust and clinically credible tools for clinical-process
management.

    APPLY CLINICAL KNOWLEDGE FOR BETTER HEALTH QUALITY AND REDUCED MEDICAL
EXPENSES. The collection, standardization and analysis of clinical data is
complicated, time intensive and requires specialized capabilities. We believe
that very few health care organizations possess these resources or capabilities.
Our products are designed to collect and analyze comprehensive clinical data in
order to improve the delivery of care. As an application service provider, we
offer our customers cost-effective access to remotely hosted data supported by
sophisticated processing technology and analysis methods. In addition, our
consulting for health care providers complements our Internet-based solutions
with services for care process improvement, management infrastructure,
leadership development and more.

OUR VALUE PROPOSITION

    Our value proposition to our customers is based on enabling them to manage
their clinical operations using our data-sharing technologies, databases and
proprietary clinical algorithms. Our approach identifies clinical inefficiencies
and medical errors and thereby offers the opportunity to improve the quality of
care and reduce costs. Additionally, we host our customers' clinical data and

                                       4

provide real-time access to that data, which reduces their fixed cost of
information technology while increasing reporting flexibility.

    Customers gain value from our products in three principal areas:

    IMPROVING CLINICAL PROCESSES.  Many tests and therapies that are performed
on patients do not improve outcomes or may pose undue risk. Moreover, many
patients do not receive indicated preventative therapies or are placed at risk
by oversights in drug regimens or in pre-operative preparations. Our products
enable our customers to strengthen their business performance by improving the
quality of care they deliver and avoiding medical errors and unnecessary
treatments.

    LOWERING THE COST OF CARE DELIVERY.  In hospitals and health systems, our
products reduce the need for manual data collection and for tracking of clinical
events. Our Lifecycle Decision System databases and outsourcing tools reduce the
need for pharmaceutical makers to have specialized in-house staff to manage the
strategic drug development process. Because our products are vendor neutral and
operate over the Internet, we enable our customers to realize substantial value
from their historical investment in legacy systems. In addition, our Care Data
Exchange will reduce costs by using a peer-to-peer architecture to provide
secure, real-time access to clinical results, patient demographics, medical
records and other clinical data from the original source.

    IMPROVING THE WAY HEALTH CARE CONSTITUENTS INTERACT.  Our products provide
service integration by enabling health care constituents to share relevant
clinical information. Our products enable hospitals and health systems to
provide clinical-data access to physicians at the point of care and to share
data with other health care entities.

OUR STRATEGY

    Our objective is to become the leading provider of Internet-based products
to facilitate improvements in health care quality and efficiency. The primary
components of our strategy include:

    OFFER COMMUNITY-BASED SOLUTIONS.  Our primary focus is at the community
level, where the overwhelming majority of people receive clinical services. Our
products and services support the key participants in local health care
delivery: hospitals, health plans, pharmaceutical and biotechnology companies,
physicians and consumers. We offer a comprehensive suite of Internet-based
products and services that allow different participants in local health care
systems to manage their role in care delivery while collaborating with other
participants. As one or more of our products become accepted within a community,
our other products become more valuable and more likely to be used in that
community.

    DEVELOP NEW PRODUCTS BASED ON OUR PROPRIETARY KNOWLEDGE AND DATA ASSETS.  We
have developed a substantial and rapidly growing proprietary online data asset
in a single location and format encompassing millions of care encounters. We
maintain proprietary, rigorously validated clinical algorithms. Our data and
knowledge bases are unique because of their clinical detail and linkage to
ongoing relationships with active customers. We are leveraging our proprietary
database to develop and introduce other Internet-based products. For example, in
the fall of 1999, we introduced our Lifecycle Decision System product to
pharmaceutical and biotechnology companies for outsourcing key functions and
performing online pharmacoeconomic analysis.

    CROSS-SELL PRODUCTS.  We are developing strong relationships with hospitals,
health systems and pharmaceutical companies. We intend to enhance these
relationships by developing and selling additional complementary products to
these customers. While each of our products is designed to satisfy the needs of
a particular type of customer, customers frequently purchase more than one type
of product or enhancements of existing products. For example, we believe that
hospitals that use our Care Management System to manage clinical processes are
more likely to use our Care Data Exchange to

                                       5

exchange clinical data and to extract data to facilitate the development of
their databases. Additionally, we can serve our high-level user base by
providing future opportunities for third-party services to be offered through
our distribution channels.

    LEVERAGE OUR TECHNOLOGY PLATFORM.  Our products use a common technology
platform, including common architecture, data structures, analytic processing
tools, clinical algorithms and telecommunication protocols. Additionally, our
products frequently integrate with a variety of other vendors' products or
enable direct interactions among those products. By using the Internet and
serving as a centralized application service provider, our solution represents a
high-value proposition for our customers. Furthermore, since our products are
technologically intensive and connect disparate industry segments, customers
cannot replicate our products without incurring substantial costs.

    PURSUE TARGETED STRATEGIC RELATIONSHIPS AND ACQUISITIONS.  We intend to
pursue strategic relationships and acquisitions that would bolster our
distribution channels in core areas or expand our service offerings to
customers. For example, on January 12, 2001, we acquired Strategic Outcomes
Services, Inc., a pharmacoeconomic consulting firm based in Research Triangle
Park, North Carolina, to expand our consulting services to the pharmaceutical
and biotechnology industries and to improve our ability to sell our
pharmaceutical and biotechnology products. We plan to continue to seek targeted
partnerships and acquisitions that are consistent with our objective to improve
quality and efficiency in health care.

PRODUCTS AND SERVICES

    We provide an integrated suite of Internet-based products designed to
access, analyze and apply clinical information to improve the process of
decision surrounding the point of care. Our customers use these products to
build relationships and to improve the quality and delivery of clinical care. We
also provide consulting services to compliment our products. To date, we have
deployed products for both health care providers and for pharmaceutical and
biotechnology companies. For health care providers, we offer our Care Management
System, Free Benchmarking( TM), Care Data Exchange, Technology Assessment Tools
and consulting services. For pharmaceutical and biotechnology companies, we
offer our Lifecycle Decision System and consulting services.

CARE MANAGEMENT SYSTEM

    The CareScience Care Management System (formerly called CaduCIS) applies
cutting-edge analysis methods to help health care provider organizations improve
their clinical performance by allowing users to:

    - identify the underlying causes of high complication rates and clinical
      performance opportunities;

    - achieve measurable care process improvement and efficiency gains;

    - support initiatives for profiling, case management or physician education;

    - provide instant access to the outcomes information and practice patterns
      that guide medical management;

    - automate the process of data gathering, analysis and reporting;

    - establish a high-validity, clinically rigorous basis for collaboration
      between physicians and management; and

    - reduce health care institutions' financial and legal risks.

    The Care Management System helps health care provider organizations take
advantage of the vast data resources that often remain trapped or underutilized
within organizations. The Care Management

                                       7

System's Internet-based interface enables medical officers, clinical analysts,
physicians and health care professionals to do their jobs more effectively. In
particular, the Care Management System helps:

    - quickly identify problem areas;

    - hypothesize about care process or outcome improvement opportunities;

    - evaluate and test these hypotheses against real data; and

    - establish likely causes of problems before intervention.

    We typically sell the Care Management System pursuant to three- to five-year
contracts. Contract pricing is estimated based on a per-encounter basis.
Customers typically have unlimited access to data and are supported by an array
of telephone and email help, data validation and management, product training
classes and ad-hoc services.

    FEATURES

    Some features of the Care Management System are:

    COMPLICATION IDENTIFICATION:  We apply sophisticated disease- and
outcome-specific risk adjustment methodologies in the Care Management System to
accurately distinguish between treatment variations and patient risk factors or
new complications and pre-existing conditions.

    CONTINUOUS-SCALE RISK ASSESSMENT:  The Care Management System calculates
patient-specific risks for outcomes including mortality, complication frequency,
complication morbidity, length of stay, charges and cost.

    INTEGRATED DATABASE:  We construct an integrated, longitudinal clinical and
financial resource detail database for the Care Management System using a health
care provider's existing data from its core patient information systems.

    UNIFIED MEDICAL LANGUAGE:  The Care Management System incorporates the
National Library of Medicine's Unified Medical Language System to create common
coding definitions about tests, therapies, interpretations and related
activities across facilities.

    AD-HOC QUERIES:  The Care Management System includes an ad-hoc query feature
that allows users to construct questions using "common language" terms.

    CARE PROCESS ANALYSIS:  The Care Management System automatically applies our
algorithms to daily resource data and clinical outcomes data for the
identification of unique care process pathways by disease and "best practice"
within each path.

    CARE MANAGEMENT SYSTEM CASE STUDY EXAMPLE

    THE CARE MANAGEMENT SYSTEM ALERTED A HOSPITAL TO A PROBLEM WITH MEDICAL
ERRORS IN PATIENTS WITH AN INTESTINAL BLOCKAGE. USING THE TOOL, USERS DETERMINED
THAT THE AMOUNT OF INTRAVENOUS FLUID PROVIDED WAS TOO MUCH FOR SOME OF THE
PATIENTS WITH WEAKER HEARTS. THAT EXCESS FLUID RESULTED IN A DANGEROUS CONDITION
WHERE FLUID ACCUMULATES IN THE LUNGS AND BREATHING BECOMES DIFFICULT. THIS
COMPLICATION WAS COSTLY DUE TO THE NEED FOR DRUG TREATMENT TO REMOVE THE EXTRA
FLUID AS WELL AS LAB AND X-RAY TESTS TO MONITOR THE TREATMENT. IN LESS THAN 5%
OF THE TIME IT WOULD HAVE TAKEN WITHOUT THE CARE MANAGEMENT SYSTEM, TWO USERS
WERE ABLE TO QUICKLY IDENTIFY A TOTAL OF 250 CASES OF THIS COMPLICATION
REPRESENTING MORE THAN $1.4 MILLION IN UNNECESSARY, UNCOMPENSATED FEES.

                                       8

FREE BENCHMARKING

    CareScience's Free Benchmarking service on the Internet (formerly called
CaduCIS Net) helps health care providers understand how their clinical
performance compares against risk-adjusted standards drawn from Medicare and
all-payor state data, where available. Free Benchmarking is used to generate our
name awareness, drive requests for more information concerning our products and
services and as a service to the health care provider community.

    At no cost to registrants, Free Benchmarking lets qualified hospitals,
physician groups and health systems pinpoint opportunities for improvement
across diseases and compare patient mix and outcomes among institutions in a
defined local or national marketplace. To better manage these processes, these
health care participants need to subscribe to our Care Management System.

    Free Benchmarking provides access to publicly available data: MEDPAR files
of nationwide Medicare patients and available state-sponsored inpatient
databases. These databases have been risk-adjusted using CareScience's
proprietary techniques and include standardized outcomes by ICD-9 principal
diagnosis, DRG, MDC and ICD-9 principal procedure for facility benchmarking and
comparative screening purposes. Flags highlight diseases where results are
significantly better or worse than benchmarked performance, to focus attention
on high-impact diseases for quality or cost improvement.

CARE DATA EXCHANGE

    The Care Data Exchange (formerly called CareStandard) is a peer-to-peer
technology being developed by us, which will allow health care organizations to
share patient information across locations--allowing providers direct access to
patient data when and where it is most needed--at the point of care. The Care
Data Exchange will provide secure, real-time Internet access to clinical
results, patient demographics, medical records and other critical data from the
original source.

    The Care Data Exchange is expected to offer:

    - cross-enterprise and health system participation;

    - Internet-based access to indexed patient records;

    - plug-and-play technology to interface with existing information systems;

    - real-time peer-to-peer data sharing; and

    - local control of business relationships and source data.

    The Care Data Exchange will give individual health care organizations the
ability to store and manage their own data while making it accessible to all
authorized users within a designated network. This peer-to-peer approach reduces
the cost of data sharing while minimizing the competitive issues surrounding
data ownership and access privileges.

    Care Data Exchange users will include:

    - hospitals and health systems;

    - independent physician groups;

    - clinics and outpatient facilities;

    - labs and ancillary care providers;

    - public health agencies;

    - health plans and employers; and

    - pharmacies.

                                       9

    Assuring that all necessary clinical information is available at the point
of care can significantly reduce medical errors, eliminate unnecessary and
redundant treatments, and improve the process of health care. Together, the
elements of the Care Data Exchange help overcome the financial, competitive, and
technical obstacles to building the alliances and data-sharing capabilities
necessary to empower caregivers, benefit patients, and protect the autonomy of
participating institutions.

    We are entering into agreements with other vendors to become our Care Data
Exchange partners. As a Care Data Exchange partner, a vendor's Internet
solutions can be integrated into the Care Data Exchange peer-to-peer network,
enabling a broader range of data-sharing capabilities. In addition, we and our
partners intend to offer implementation, integration and support services to
optimize the use of the Care Data Exchange and our other technologies.

    The Care Data Exchange is currently under development in Santa Barbara
County, California. The full implementation of the Santa Barbara County Care
Data Exchange pilot project will lead to nationwide availability of Care Data
Exchange technologies later in 2001. This project is the result of a partnership
between us and the California HealthCare Foundation, a non-profit philanthropic
organization. Importantly, we are designing the Care Data Exchange to be highly
scalable and capable of being expanded at low marginal cost. Markets for this
health care information utility can be accessed on a community-by-community or
health system-by-health system basis.

    CARE DATA EXCHANGE HYPOTHETICAL EXAMPLE

    A PHYSICIAN IS TREATING A NEW PATIENT WHO STATES THAT HE WAS RECENTLY SEEN
IN A HOSPITAL EMERGENCY ROOM BY ANOTHER PHYSICIAN AND HAD A PRESCRIPTION FILLED
THAT HE CAN'T REMEMBER. THE PHYSICIAN IS ABOUT TO ORDER AN EXPENSIVE SERIES OF
LABORATORY TESTS, BUT BEFORE SHE SUBMITS THE ORDER, SHE RETRIEVES THE PATIENT'S
LAB RESULTS FROM THE EMERGENCY ROOM AND THE PATIENT'S PRESCRIPTION HISTORY FROM
THE LOCAL PHARMACY. SHE DISCOVERS THAT THE LAB REGIMEN THAT SHE WAS ABOUT TO
ORDER WAS ALREADY COMPLETED BY THE HOSPITAL AND THAT THE PATIENT HAD MORE THAN
ONE ABNORMAL RESULT. ONCE AGAIN USING THE CARE DATA EXCHANGE, SHE ORDERS A
SINGLE FOLLOW UP LAB TEST AND AN IMPORTANT PRESCRIPTION. FORTUNATELY, THE
PHYSICIAN IS ALERTED IMMEDIATELY TO A DRUG ALLERGY THAT THE PATIENT HAD
FORGOTTEN, SO THE PHYSICIAN CHANGES HER DRUG ORDER TO ANOTHER PRODUCT. IN LESS
THAN FIVE MINUTES, THE PHYSICIAN HAS RETRIEVED IMPORTANT CLINICAL DATA AND
INITIATED A SAFE, EFFECTIVE TREATMENT.

TECHNOLOGY ASSESSMENT TOOLS

    We also offer Technology Assessment Tools--and our CareScience Certified-TM-
program--to help health care organizations evaluate Internet-based health care
technologies.

    Technology Assessment Tools allow purchasers to compare and evaluate
Internet-based health care technologies. Through an interactive, online
directory, we bring purchasers of health care Internet applications together
with technology suppliers to streamline the technology selection process.

    For health care providers seeking market intelligence, our Technology
Assessment Tools provide a product-neutral aid for the decision-making process.
Health care providers can:

    - review solutions for performance and qualifications;

    - compare competing products side-by-side;

    - consult user comments and peer reviews;

    - publish electronic requests for proposals online; and

    - join online discussion groups.

    Our CareScience Certified program is an added feature of the Technology
Assessment directory and recognizes those Internet-enabled solutions that meet
industry standards for security, interoperability and product usability.

CONSULTING FOR HEALTH CARE PROVIDERS

    Our consulting services complement our Internet-based Care Management System
and Free Benchmarking to offer winning strategies for sophisticated clinical
process management and quality improvement. Our analytical capabilities are
powerful and complex enough to help providers identify areas in which
complications are unnecessarily high or wasteful, contributing to unneeded
expense.

    We are helping health care leaders build customized care management
infrastructures that will continuously generate the knowledge necessary to more
effectively guide care decisions and meet other top-priority objectives like:

    - Optimizing the use of the Care Management System;

    - establishing a formal plan for clinical care management improvement;

    - discovering the root causes for specific, actual clinical outcomes;

    - executing a strategic plan for continuous quality and cost improvement;

    - reducing clinical costs by focusing on the expense of substandard clinical
      processes; and

    - planning performance improvement methods that will win the approval of
      everyone involved in the care management process.

    We also offer consulting services to optimize the implementation,
integration and support of the Care Data Exchange.

LIFECYCLE DECISION SYSTEM

    Our Lifecycle Decision System (formerly called CareScript) builds upon the
proprietary de-identified databases created by our other product lines, and uses
this data to answer important development, market-targeting and pricing
questions for pharmaceutical and biotechnology companies. The Lifecycle Decision
System accelerates and perfects organizational decision-making, helping
pharmaceutical and biotechnology companies create medications that perform
better for patients and the marketplace.

    The Lifecycle Decision System provides a combination of proprietary,
risk-adjusted data, Internet applications, customized extranet development and
group decision-making tools to help pharmaceutical and biotech companies
optimize their market access. Our Life Cycle Decision products foster integrated
analyses and promote systematic planning and workflow for various therapeutic
areas. Customers use our Lifecycle Decision System to:

    - identify unmet therapeutic needs;

    - quantify the efficacy of therapeutic options;

    - improve the design and execution of clinical trials;

    - reduce risks and expenses;

    - analyze clinical data more efficiently;

    - determine optimal product differentiation and positioning; and

    - increase the likelihood of achieving economic targets.

                                       11

    We strictly adhere to federal, state and local privacy regulations,
identifiable information about patients, physicians and facilities is not
available through the Lifecycle Decision System.

    LIFECYCLE DECISION SYSTEM CASE STUDY EXAMPLE

    RESEARCH DATA INDICATES THAT A NEW CHEMICAL COMPOUND DEVELOPED BY A
PHARMACEUTICAL COMPANY IS EFFECTIVE AGAINST A WIDE RANGE OF DISEASES. USING OUR
LIFECYCLE DECISION SYSTEM DATABASE AND SERVICES, THE PHARMACEUTICAL MAKER WAS
ABLE TO DETERMINE THE TYPE AND FREQUENCY OF THOSE DISEASES IN UNITED STATES
HOSPITALS NATIONALLY, REGIONALLY AND LOCALLY. THE LIFECYCLE DECISION SYSTEM ALSO
DETERMINED THE SEASONAL AND AGE-RELATED VARIABILITY OF THOSE DISEASES. WE EXPECT
THAT FURTHER USE OF THE LIFECYCLE DECISION SYSTEM DATA AND ANALYTIC TOOLS WILL
SHOW HOW EXISTING PHARMACEUTICAL PRODUCTS ARE USED TO TARGET THESE DISEASES. IT
WILL ALSO BE ABLE TO REVEAL THE EXISTING VARIABILITY IN TREATING THESE
CONDITIONS WITH CURRENT PHARMACEUTICAL PRODUCTS, THE CLINICAL OUTCOMES FOR EACH
EXISTING APPROACH AND THE UNMET NEEDS OF PATIENTS WITH THESE DISEASES. THIS
INFORMATION WILL ENABLE THE PHARMACEUTICAL MAKER TO DETERMINE THE MOST
ATTRACTIVE COMMERCIAL OPPORTUNITY AND PROPER CLINICAL TARGET FOR THE NEXT, MORE
EXPENSIVE PHASE OF THE FOOD AND DRUG ADMINISTRATION APPROVAL PROCESS.
SPECIFICALLY, THE PHARMACEUTICAL MAKER CAN UNDERSTAND THE RELATIVE IMPORTANCE OF
DISEASES TO TARGET, AND, FOR APPLICABLE DISEASES, WHEN TO START AND WHERE TO
CONDUCT ITS TRIAL TO MINIMIZE ITS COSTS AND MAXIMIZE ITS LIKELIHOOD OF SUCCESS.

CONSULTING FOR PHARMACEUTICAL AND BIOTECHNOLOGY COMPANIES

    Our Consulting Services complement our Internet-based Lifecycle Decision

TECHNOLOGY

    We have developed a core set of shared technologies that underlie all of our
products The three major components of these core technologies are:

    - web hosting;

    - the care data exchange; and

    - data access and reporting applications.

    Each component is briefly described below.

    WEB HOSTING

    We operate our own web-hosting technology that provides a complete set of
security, monitoring, high-availability servers and large-scale disk storage.
Given that our web hosting supports our applications, we operate as an
application service provider so that we can rapidly implement and upgrade our
products at low cost. We provide our customers with an Internet-based
environment where computation intensive functions are supported with high
security, performance, availability and scalability. All of our applications are
accessible through a standard Internet browser. Customer-specific databases are
integrated by an analysis layer and a communications layer using a multi-tier
server architecture. We maintain security through formal policies and procedures
as well as technologies used to protect the integrity of the systems and the
confidentiality of the sensitive data they contain. Performance and availability
are maintained through a redundant design that allows for continued operation in
the event of failure of individual critical components, as well as automated
monitoring to detect failures.

    CARE DATA EXCHANGE

    The Care Data Exchange integrates health care data from disparate sources
over the Internet. This tool manages comprehensive, patient-level collection of
information including patient history, risk factors, diagnosis, test results,
therapies applied and their resultant outcomes. It can process a single record
or a large group of records, and is optimized for efficiency and scalability.
This technology provides our customers secure, online access to advanced
standard and user-defined validation rules and automatic validation reports, as
well as on-line tools that manage repair or replacement of

                                       13

erroneous data. We facilitate process or workflow management through scheduled,
automatic data file retrieval, network status monitoring, automatic error
handling, and pre-planned capacity for scalability. Building from this
foundation of open standards, we add custom, value-added data structures and
dictionaries to capture clinical services, payor, operating unit, test, therapy
and demographic information using standard definitions.

    The Care Data Exchange provides a set of core functions and an optional set
of service engines that perform specialized functions on the data accessed by
the Care Data Exchange. Any data accessed by the Care Data Exchange can be
stored in a data warehouse for future access and to support reporting
applications. The core functions in the Care Data Exchange include:

    - Data integration;

    - Validation;

    - Authentication;

    - Encryption;

    - Auditing; and

    - Performance monitoring

    The service engines in the Care Data Exchange are briefly described below.

    UNIVERSAL CORRELATION SYSTEM.  The Universal Correlation System is used to
identify person-specific identities across an enterprise or community. It
consists of a set of neural network algorithms that use multivariate analysis to
create new person objects or to match person identities to an existing object.
This engine underlies the peer-to-peer tools that support clinical data sharing
and can be used to create a single identity for the patients treated in a care
management customer.

    CLINICAL ANALYSIS ENGINE.  The clinical analysis engine adds outcome risks
and complication flags to Care Data Exchange data. It draws from rules,
parameters and other content and introduces three classes of variables into
patient-specific data:

    - RISK ASSESSMENT.  This sub-service calculates patient-specific risks for
      outcomes including mortality, complications, episode duration, length of
      stay, cost, emergency room visits, specialist referrals and
      hospitalizations. Patient-specific risks are computed for each diagnosis,
      outcome and utilization measure, using more than 5,000 severity assessment
      equations.

    - THERAPEUTIC NORMS.  This sub-service identifies specific therapeutic norms
      in cases where physicians have variant practices in comparison to their
      peers, risk adjusted for patient differences. Practice-style variations
      can be compared to outcomes in order to focus inquiry on practice
      decisions that significantly impact outcomes.

    - COMPLICATION IDENTIFICATION.  This sub-service distinguishes between newly
      identified complications and pre-existing conditions for both surgical and
      medical conditions. Risk assessment algorithms are used to separate
      patient determinants of complications from those related to the facility
      or physician.

    UNIFIED MEDICAL LANGUAGE.  The Unified Medical Language assigns all incoming
clinical terms to a standard clinical vocabulary based on the National Library
of Medicine Unified Medical Language System. This engine allows comparisons of
tests and therapies across facilities and application of treatment-specific
rules. This engine also supports outbound queries by matching syntactical
variants and substitute terms to requested search terms.

    HEALTH INFORMATION LOCATOR.  The Health Information Locator enables the
secure exchange of clinical data between cooperating health-care organizations.
This engine stores and accesses metadata,

                                       14

which identifies the location of patient-specific health care data. This engine
manages the requesting, directing and security process for data sharing. It is
designed to be used by or incorporated into authorized third party applications.

    RESOURCE ACCESS DIRECTORY.  The Resource Access Directory manages the
security and access rules for accessing data from the Care Data Exchange. This
engine creates and manages policies determining which users get to see which
data for which patient at what time. This engine will be operated in compliance
with security regulations required in the Health Insurance Portability and
Accountability Act of 1996, as they become known with certainty.

    DATA ACCESS AND REPORTING APPLICATIONS

    Users and authorized system can access data from our data warehouses or from
the Care Data Exchange by using several data access and reporting applications.
These are all designed, implemented and operated by us. Each is briefly
described below.

    QUERY APPLICATIONS.  Query applications allow health system and
pharmaceutical users to access and analyze data stored in our data warehouses.
Using our query applications, users perform a variety of operations and tasks on
data, including population analysis, time trending, benchmarking, hypothesis
testing and performance evaluation.

    WORKFLOW APPLICATIONS.  Workflow applications are used by health system and
pharmaceutical users to manage the business processes of patient care and drug
development, respectively. These applications allow these users to interact with
data, merge outside information such as strategy, business process, decision
goals, and to progress along pre-determined or customized decision processes.

    ACCESS APPLICATIONS.  Access applications are used to support patient care
needs at the point of care by providing patient-specific data access from our
clinical data repositories or the Care Data Exchange Health Information Locator.
These applications are platform independent and can be incorporated into
numerous third-party applications.

STRATEGIC RELATIONSHIPS

    We have developed strategic relationships with organizations that supply
important inputs into our products. We have a long-standing technology transfer
relationship with the University of Pennsylvania, from which we have licensed
intellectual property and methods. The University and management began this
relationship in 1987 and it has grown over time as new methods and properties
have been added to our portfolio. From time to time, faculty of the University
of Pennsylvania provide informal advice and consultation regarding refinement of
our existing methodologies and/or advice regarding potential areas of new
development. This informal advice is not material to our results of operations.
Dr. David J. Brailer, our Chairman, Chief Executive Officer and a member of our
Board of Directors, is an adjunct faculty member of the University of
Pennsylvania. The University of Pennsylvania Health System is also a
non-material customer of CareScience. Also, the University owns less than one
percent of our common stock. The University does not have the ability to direct
or influence our operations, except as licensor under the license agreement and
through its ability to vote its 124,900 shares of common stock. We are not aware
of any agreements among the University and any other parties, such as other
shareholders, to influence our management or operations. We have no agreements
with the University, informal or formal, other than a non-material customer
agreement and the license agreement.

    We entered into our license agreement with the University on July 1, 1993
and amended it effective on April 1, 1995 and May 1, 1997. That agreement
expires on March 31, 2025, unless sooner terminated by the University upon our
default or sooner terminated by us upon 90 days' notice to the University. Under
the license agreement, the University grants a royalty-bearing, worldwide,
exclusive

                                       15

license to us for the use of the software code which forms the basis for our
technology and the proprietary analytic routines which were used to create the
software, as well as the right to sublicense the software, to create derivative
works from the software and to enter into end-user agreements with our
customers. We pay the University royalties for the license in an amount equal to
a percentage of fees we receive for allowing others to use or to sublicense the
technology. We are obligated to pay the University a minimum level of $75,000
per year in royalties, regardless of the fees we collect. If we fail to pay the
minimum level of royalty fees every year, the University has the option to
convert our exclusive license to a non-exclusive license. The University retains
the right to publish the material we license, although the University must
notify us in advance of their intention to publish in order that a filing for
intellectual property protection of such material may be made. In the event of
such publication, to the extent that intellectual property protection is not
available for such material, the University agrees to negotiate with us in good
faith as to whether the disclosure can be appropriately modified or withheld,
although we do not have a right to prevent any such disclosure. The University
has not disclosed any information about the licensed material and, to our
knowledge, the University has no plans to do so. Pursuant to the license
agreement, we agree to indemnify and hold the University harmless against claims
which arise out of the use of the licensed material by us or parties with which
we contract.

    We have entered into a consulting agreement with California HealthCare
Foundation for a term beginning October 1, 1999 until the earlier of
September 30, 2002, or the completion of an extensive work plan, unless sooner
terminated. The work plan includes the production of a local business model for
the Internet-based cooperative sharing of clinical health information that may
then be replicated in other localities. The purpose of the agreement is to
establish a management office to facilitate the development and maintenance of a
care data utility for the sharing of clinical health care data in Santa Barbara
County. Under the terms of the agreement, the Foundation is required to make
payments to us upon various milestones, including the receipt and approval of
narrative and financial reports, work plans, deliverables and budget
projections, which may not exceed a total of approximately $4.6 million. The
Foundation owns all intellectual property rights with respect to the project,
subject to a license between us and the Foundation described below. Either party
may terminate the agreement due to the other's breach that is not cured within
45 days of written notice from the non-breaching party.

    We also entered into a license agreement with the Foundation on October 2,
2000. That agreement expires on October 2, 2030, unless sooner terminated by the
Foundation upon our default or sooner terminated by us upon 90 days' notice to
the Foundation. Under the license agreement, the Foundation grants a
royalty-bearing, worldwide, exclusive license to us for the use of the software
code which forms the basis for the Care Data Exchange, as well as the right to
sublicense the software, to create derivative works from the software and to
enter into end-user agreements with our customers. We pay the Foundation
royalties for the license in an amount equal to a percentage of fees we receive
for allowing others to use or to sublicense the technology. We are obligated to
pay the Foundation a minimum level of $25,000, $41,250, $57,500, $73,750 and
$90,000 per year in royalties for the year 2001, 2002, 2003, 2004 and 2005 and
each year after 2005, respectively, regardless of the fees we collect. If we
fail to pay the minimum level of royalty fees every year, the Foundation has the
option to convert our exclusive license to a non-exclusive license. Pursuant to
the license agreement, we agree to indemnify and hold the Foundation harmless
against claims which arise out of the use of the licensed material by us or
parties with which we contract.

MARKETING AND SALES

    We sell our products through a geographically distributed sales force in the
health care provider and pharmaceutical and biotechnology markets. We have

These individuals are becoming increasingly prominent in senior management
positions and are gaining accountability as medical management becomes essential
to health system operations.

    We have supplemented our brand identity by the free distribution of Free
Benchmarking. This tool is used by more than 3,000 health care organizations.
Also, we recently began publicizing the launch of the Santa Barbara Care Data
Exchange demonstration project in Santa Barbara County, California, and our
Technology Assessment Tools. These efforts will continue our positioning as an
innovator of Internet-based clinical products.

    We have used the Care Management System to build a distribution channel to
health care systems and the Lifecycle Decision System for pharmaceutical makers
and biotechnology firms. We sell our products into these sectors through a
national sales force of highly experienced sales executives who manage all
aspects of sales and also generate cross selling referrals to other products.
Within our distribution channels, we cross-sell our other products in the
following ways:

    - Care Management System customers can benefit by implementing the Care Data
      Exchange;

    - the Care Data Exchange can be complemented by our consulting services and
      our data hosting and access services; and

    - our pharmaceutical and biotechnology consulting customers can benefit by
      implementing the Lifecycle Decision System and the Lifecycle Decision
      System can be complemented by those consulting services.

PRODUCT DEVELOPMENT

    We have been a leader in the management of health care quality and
efficiency using the Internet by focusing on changes in the analysis and
application of information to patient care. Our technology arose from
fundamental research in risk assessment, outcomes measurement, care-process
analysis, medical-language processing and data integration and validation at the
University of Pennsylvania, beginning in the late 1980s. Researchers have
published more than ten scientific manuscripts about the methodologies
underlying our products and other publications are underway at this time
regarding new advances, which we intend to commercialize in the future.

    From this research base, we have built a track record for commercializing
significant advances in clinical management and information-sharing products. We
have accomplished this by nurturing

                                       17

technology transfer-relationships with scientists, from which we can acquire and
commercialize new technologies. Our development is coordinated by our research
center, which is staffed with our employees and by academic scientists and which
can balance the academic needs of scientists with proprietary requirements. Our
research center works closely with our product engineers to prototype new
innovations.

    In addition to design of products in the laboratory, we refine our products
in demonstration projects. For example, we tested our Care Management System in
a group of health systems, and our consulting services for health care providers
in two major health systems before commercialization. We are currently
demonstrating our Care Data Exchange in California.

COMPETITION

    Each of our product lines face different competitors, although we believe
that our total solution as a whole has no single competitor. We have few pure
Internet-based competitors, but Internet-based competition is increasing and
many off-line organizations are adding Internet capabilities. We believe that
competition in our industry is based on the performance, utility, price and
level of comprehensiveness of products.

    CARE MANAGEMENT SYSTEM.  There are no dominant care-management firms serving
the hospital or health plan markets, and Internet-based entities have not
established a credible base in this market. Rapid growth and the demand for a
new generation of care-management tools has opened this market sector to new
entrants. Therefore, most Care Management System competition arises from
clinical information system companies that offer data warehousing or
benchmarking. These firms offer large-scale transactional databases and
applications, but their current data warehouses do not have clinical analysis
methodologies or the ability to change the way that health care constituents
interact with each other and with physicians or consumers. These firms tend to
be administratively oriented and focus on external comparisons rather than the
internal management of care.

    CARE DATA EXCHANGE.  The Care Data Exchange faces a diverse array of
competitors, including consulting firms, technology vendors, and local efforts.
Most vendors offer a proprietary approach with pre-packaged end-user
applications rather than allowing customers their choice of applications.
Additionally, these products are aimed primarily at the flow of claims and
financial data, rather than clinical data. Large consulting firms have presented
plans for new activities in data sharing. However, their core business model is
to focus on application implementation, not data sharing. In addition, these
consulting firms tend to have long-standing relationships with large hospital
information system vendors that prevent them from being vendor-neutral, and they
have not yet been able to adapt their value proposition to the Internet.

    LIFECYCLE DECISION SYSTEM.  The Lifecycle Decision System competes with
contract research organizations and pharmaceutical information companies.
Contract research organizations are increasingly offering pharmacoeconomic
studies and outcomes research to pharmaceutical companies and directly to the
health care market. Pharmaceutical information companies are the largest
suppliers of information to the pharmaceutical industry. However, these firms
have not focused on market economics or outcomes, and the information provided
is generally limited to traditional market research data and analysis.
Generally, these firms do not offer complete outsourcing of strategic analysis
for drug development. Many of these groups also lack integrated patient-level
clinical, laboratory and pharmacy information over time.

GOVERNMENT REGULATION

    The collection, storage and transmission of personal information about an
individual, especially health care information, is extensively regulated by
federal and state governmental authorities in the

                                       18

United States. A variety of federal and state laws protect a person's medical
records and information as confidential, including the federal Health Insurance
Portability and Accountability Act of 1996. In addition, several federal and
state privacy laws have strict requirements governing the treatment of
particularly sensitive health data, such as information regarding an
individual's HIV status, mental health, or substance abuse problems. Widespread
access to the Internet, and the high speed at which data is transferred over the
Internet, make this medium especially vulnerable to breaches of confidentiality.

    As required by the Health Insurance Portability and Accountability Act of
1996, the U.S. Department of Health and Human Services has promulgated final
regulations to protect the confidentiality of individually identifiable health
information that is stored or transmitted electronically. This information is
referred to as "protected health information." The regulations will be effective
on April 14, 2001 and all affected organizations will be required to be by
April 14, 2003. The Health Insurance Portability and Accountability Act of 1996
privacy regulation prohibits health care providers, health insurance plans and
health care clearinghouses, referred to as "covered entities," from using or
disclosing protected health information without the individual's authorization,
except as permitted by the proposed regulations. Additionally, the regulation
requires a covered entity to protect an individual's medical records from
unauthorized disclosure for the life of the individual plus two years after the
individual's death.

    The regulation also outlines procedures and policies that covered entities
must establish regarding the collection, storage and dissemination of protected
health information. Finally, the privacy regulation also governs business
associates of a covered entity who receive protected health information from a
covered entity.

    In some of our business relationships we will be subject to the Health
Insurance Portability and Accountability Act of 1996 privacy regulation as a
covered entity, and in other business relationships we will be considered a
business associate of a covered entity. Over the two years following the
effective date of the final regulation, we will need to ensure that our internal
policies and procedures meet the requirements of the regulation. We will also
need to ensure that our business relationships with persons who share
information with us, and with whom we share information, meet the requirements
of the regulations. Under the final regulation, in many situations our exchange
of protected health information will not require a patient's authorization under
the regulation. However, even in these situations we must be very careful to
safeguard the information against receipt by persons other than the intended
recipient. We will need to implement technical safeguards to ensure that
information in our systems can only be accessed by authorized persons. We do not
expect to significantly modify our products or business operations or materially
increase our expenses in response to currently proposed regulations.

    Two years after the final regulation becomes effective, we will be subject
to periodic reviews by the federal government to verify our compliance with the
regulations. If we are found not to be in compliance, we may have to pay
penalties. Additionally, if we are found to have misused any protected health
information, we may face substantial monetary penalties and our management or
employees could face imprisonment.

    Recently, the Secretary of the U.S. Department of Health and Human Services
invited interested parties to offer comments on the final regulations. Those
comments are due by March 31, 2001. While the regulations have been published as
final, the invitation for public comment may mean that these regulations may be
further amended or revised This could substantially change our responsibilities
with respect to patient consent as well as with respect to safeguards of
confidential patient information, permissible disclosures of that information
without prior patient consent, the manner of those disclosures and the storage
of that information.

                                       19

    Under the Health Insurance Portability and Accountability Act of 1996, the
privacy regulation sets a federal standard for the privacy of protected health
information; however, the Health Insurance Portability and Accountability Act of
1996 provides that state medical privacy laws will preempt the federal standard
if the state law is not contrary to and is more stringent that the federal
standard. Therefore, we will still be subject to provisions of state laws to the
extent that they preempt the federal standard. Some state laws establish strict
requirements for the maintenance and dissemination of an individual's health
records, especially when those records contain particularly sensitive data such
as HIV status, mental health information or substance abuse information.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH OUR
FINANCIAL STATEMENTS AND THE RELATED NOTES TO THE FINANCIAL STATEMENTS APPEARING
ELSEWHERE IN THIS PROSPECTUS. THE FOLLOWING INCLUDES A NUMBER OF FORWARD-LOOKING
STATEMENTS THAT REFLECT OUR CURRENT VIEWS WITH RESPECT TO FUTURE EVENTS AND
FINANCIAL PERFORMANCE. WE USE WORDS SUCH AS ANTICIPATES, BELIEVES, EXPECTS,
FUTURE, AND INTENDS, AND SIMILAR EXPRESSIONS TO IDENTIFY FORWARD-LOOKING
STATEMENTS. YOU SHOULD NOT PLACE UNDUE RELIANCE ON THESE FORWARD-LOOKING
STATEMENTS, WHICH APPLY ONLY AS OF THE DATE OF THIS PROSPECTUS. THESE
FORWARD-LOOKING STATEMENTS ARE SUBJECT TO RISKS AND UNCERTAINTIES THAT COULD
CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM HISTORICAL RESULTS OR OUR
PREDICTIONS. FOR A DESCRIPTION OF THESE RISKS, SEE THE SECTION ENTITLED "RISK
FACTORS" BELOW.

OVERVIEW

    We released our first Internet products, Care Management System (formerly
called CaduCIS) and Free Benchmarking (formerly called CaduCIS Net), in 1996.
Since our first product release, we have signed over $27 million in multi-year
contracts with customers for our products. In March 1999, we formed our Care
Data Exchange product line, and have entered into a $4.6 million contract with
the California HealthCare Foundation to develop our Care Data Exchange
technology and business model. In the fall of 1999, we formed our Lifecycle
Decision System product line. In the fall of 2000, we terminated our CareSense
and CareLeader product lines. We did not generate any revenues from the
Lifecycle Decision System, CareSense or CareLeader product lines in 1999. We
have commenced sales of the Lifecycle Decision System.

    We generate revenues from subscriptions to our Internet-based proprietary
technology applications and hosting of customer data, as well as from training,
implementation and consulting services. We sell our products individually or as
an integrated suite of products and services. We price our products on a
per-encounter basis, such as the number of a hospital's patient admissions or
outpatient visits.

    Our subscription agreements typically cover an initial three- to five-year
period with provisions for automatic renewals. We recognize training and
implementation fees, as well as subscriptions and related hosting revenues, on a
pro-rata basis over the life of the contract. We recognize consulting fees as
the program or service is delivered.

    Our contracts generally provide for payment in advance of services rendered.
Therefore, we record these payments as deferred revenues and recognize these
payments when earned in accordance with our revenue recognition policy. Our
deferred revenue balances were $820,000, $2.9 million and $3.0 million at
December 31, 1998, 1999 and 2000, respectively.

    More than 135 health care organizations subscribe to our products. Our
contract with the California HealthCare Foundation represented approximately 22%
of our 2000 revenues.

    We have incurred substantial research and development costs since inception
and have also invested in our corporate infrastructure to support our long-term
growth strategy. We expect that our operating expenses will continue to increase
as we expand our product development and sales and marketing efforts.
Accordingly, we expect to continue to incur quarterly net losses for the
foreseeable future.

    Since inception, we have incurred cumulative net losses for federal and
state tax purposes and have not recognized any material tax provision or
benefit. As of December 31, 2000, we had net operating loss carryforwards of
approximately $26.0 million for federal income tax purposes. The net operating
loss carryforwards, if not utilized, expire from 2010 through 2020. Federal tax
laws impose significant restrictions on the utilization of net operating loss
carryforwards in the event of an ownership change as defined in Section 382 of
the Internal Revenue Code. See Note 4 of the Notes to Financial Statements in
this Form 10-K for additional information regarding these carryforwards.

                                       24

    On June 28, 2000 we completed an initial public offering of 4,000,000 shares
of Common stock at a price of $12.00 per share. We received aggregate net cash
proceeds of approximately $43.4 million from the initial public offering on
July 5, 2000.

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998

    REVENUES

    Total revenues were $7.8 million, $4.4 million and $2.6 million in the years
ended December 31, 2000, 1999 and 1998, respectively. These amounts represent
increases of 80% from 1999 to 2000 and 70% from 1998 to 1999. The increase was
primarily related to revenues generated from newly signed customer contracts. We
anticipate our revenue to grow at a significant rate. The ultimate growth of our
revenue is dependent upon the timing of the signing of contracts and the
introduction of new products.

    Unrecognized revenues related to customer contracts (backlog) as of
December 31, 2000 totaled $14.3 million, of which we expect to recognize
$7.2 million in 2001 in accordance with our revenue recognition policy.

    COST OF REVENUES

    Cost of revenues were $4.6 million (excluding stock-based compensation of
$671,000), $2.5 million (excluding stock-based compensation of $121,000) and
$1.9 million in the years ended December 31, 2000, 1999 and 1998, respectively.
These amounts represent an increase of 85% from 1999 to 2000 and 32% from 1999
to 1998. The increase was primarily a result of additional costs necessary to
service new customers.

    GROSS PROFIT

    Our gross profit margin decreased to 41% in 2000 from 42% in 1999, as
compared to 25% in 1998. This decrease in gross profit margin from 1999 to 2000
is primarily related to increased costs to service anticipated customer growth.
This increase in gross profit margin from 1998 to 1999 is primarily due to
increased revenues spread over a fixed base of costs. We do not expect
significant changes in gross profit margin for the foreseeable future.

    RESEARCH AND DEVELOPMENT

    Research and development costs were $4.7 million (excluding stock-based
compensation of $78,000), $1.5 million (excluding stock-based compensation of
$20,000) and $1.7 million for the years ended December 31, 2000, 1999 and 1998,
respectively. These amounts represent an increase of 219% from 1999 to 2000 and
a decrease of 13% from 1998 to 1999.

    This increase from 1999 to 2000 is primarily due to additional research and
development costs supporting our new product development. This decrease from
1998 to 1999 is primarily due to the timing of changes in personnel. We expect
research and development costs to increase in the future as we continue the
development of products.

    As a percentage of revenue, research and development costs were 59%, 34% and
65% of revenue in 2000, 1999 and 1998, respectively. We expect the growth in
revenue to exceed the growth in research and development costs. Therefore, we
expect these costs will decrease as a percentage of revenue in the future.

                                       25

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses were $9.6 million (excluding
stock-based compensation of $598,000), $3.9 million (excluding stock-based
compensation of $92,000) and $3.2 million for the years ended December 31, 2000,
1999 and 1998, respectively. These amounts represent an increase of 146% from
1999 to 2000 and 23% from 1998 to 1999. This increase in 2000 was primarily
related to additional personnel, marketing and technical infrastructure
expenditures and in 1999 was primarily related to hiring of additional sales and
management personnel to increase and support customer growth.

    We expect that selling, general and administrative expenses will continue to
increase in the future in order to support our revenue growth and the need for
additional infrastructure.

    As a percentage of revenues, selling, general and administrative cost was
122%, 90% and 124% in 2000, 1999 and 1998, respectively. We expect the
percentage of selling, general and administrative costs to decrease in the
future as our fixed costs are spread over an increasing revenue base.

    STOCK-BASED COMPENSATION

    We granted certain stock options to our officers and employees at prices
deemed to be below the fair value of the underlying stock. The cumulative
difference between the fair value of the underlying stock at the date the
options were granted and the exercise price of the granted options was
$5.6 million. We are amortizing this amount over the four to seven year vesting
periods of the granted options. Accordingly, our results from operations will
include stock-based compensation expense at least through 2006. We recognized
$1.3 million and $233,000 of this expense during the years ended December 31,
2000 and 1999, respectively.

    INTEREST INCOME AND EXPENSE

    Net interest income was $1.1 million and $78,000 for the years ended
December 31, 2000 and 1999, respectively. This amount arose primarily from
investment interest income offset by interest expense from capital lease
obligations. Net interest expense for the year ended December 31, 1998 was
$419,000. This amount arose primarily from interest expense from notes payable
and capital lease obligations, partially offset by investment interest income.
The increase in net interest income in 2000 from 1999 is due to higher
investable cash balances resulting from the cash received from our initial
public offering on June 28, 2000.

    The change from net interest income in 1999 from net interest expense in
1998 is due to higher investable cash balances resulting from the cash received
from the sale of our series C preferred stock in a private transaction in
December 1998 and a reduction in interest expense in 1999 due to the conversion
of the notes payable to shareholder into our series G preferred stock in
December 1998.

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations and funded our capital
expenditures through the public and private sale of equity securities,
supplemented by private debt and equipment leases. We believe that available
cash and investment balances at December 31, 2000 will be sufficient to fund
anticipated capital expenditures and working capital requirement for at least
the next 12 months. As of December 31, 2000, we had $29.9 million in cash and
investment balances and working capital of $25.5 million.

    Net cash used in operating activities was $7.5 million and $1.4 million for
the years ended December 31, 2000 and 1999, respectively. For those periods, net
cash used in operating activities was primarily to fund losses from operations.

                                       26

    Net cash used in investing activities was $5.7 million and $195,000 for the
years ended December 31, 2000 and 1999, respectively. Investing activities
consisted primarily of purchases of and proceeds from available-for-sale
securities and property and equipment.

    Net cash from financing activities was $36.6 million and a use of $370,000
for the years ended December 31, 2000 and 1999, respectively. The net cash from
financing activities in 2000 consisted primarily of the proceeds of the initial
public offering net of the payment of dividends and redemption of preferred
stock. Net cash used in financing activities in 1999 consisted primarily of
payments on capital lease obligations.

    As we execute our strategy, we expect significant increases in our operating
expenses to fund development of current and new product lines. Presently, we
anticipate that our existing capital resources will meet our operating and
investing needs through at least 2002. After that time, additional funding may
not be available on acceptable terms or at all. If we require additional capital
resources to grow our business, execute our operating plans or acquire
complementary businesses at any time in the future, we may seek to sell
additional equity or debt securities or secure additional lines of credit, which
may result in ownership dilution to our shareholders.

    RECENT ACCOUNTING PRONOUNCEMENTS

    In December 1999, the SEC issued Staff Accounting Bulletin ("SAB") No. 101,
"Revenue Recognition in Financial Statements." SAB 101 expresses the views of
the SEC staff in applying generally accepted accounting principles to certain
transactions. Our financial statements and related disclosures for 1997, 1998
and 1999 are in compliance with SAB 101.

    Effective July 2000, the Company adopted Statement of Financial accounting
Standards No. 130 (SFAS 130), "Reporting Comprehensive Income" which requires
the Company to report and display certain information related to comprehensive
income. Comprehensive income includes net income and other comprehensive income.
Other comprehensive income is classified separately as unrealized gains on
available for sale securities.

                                  RISK FACTORS

    WE ARE SUBJECT TO A HIGH DEGREE OF RISK. THE RISKS AND UNCERTAINTIES
DESCRIBED BELOW ARE NOT THE ONLY ONES FACING US. ADDITIONAL RISKS AND
UNCERTAINTIES THAT WE ARE UNAWARE OF, OR THAT WE CURRENTLY DEEM IMMATERIAL, ALSO
MAY BECOME IMPORTANT FACTORS THAT AFFECT US. IF ANY OF THE FOLLOWING RISKS
OCCUR, OUR BUSINESS, FINANCIAL CONDITION OR RESULTS OF OPERATIONS COULD BE
MATERIALLY AND ADVERSELY AFFECTED. IN THAT CASE, THE TRADING PRICE OF OUR COMMON
STOCK COULD DECLINE.

                         RISKS RELATED TO OUR BUSINESS

OUR BUSINESS IS DIFFICULT TO EVALUATE BECAUSE WE OPERATE IN A NEW INDUSTRY AND
OUR OPERATING HISTORY IS LIMITED.

    Because of our limited operating history it is difficult to evaluate our
business and prospects. We launched our first Internet-based product in 1996.
Our business presents the difficulties and expenses frequently encountered by
companies in the early stage of development, coupled with the risks and
uncertainties faced by companies in new and evolving markets such as the market
for Internet-based software applications. We may not be able to successfully
address these challenges. If we fail to do so, we may continue to incur losses
and the market price of our common stock would likely decline.

                                       27

WE HAVE A HISTORY OF LOSSES AND EXPECT OUR LOSSES TO CONTINUE.

    We have incurred net operating losses and negative cash flows from operating
activities from our inception. As of December 31, 2000, we had an accumulated
deficit of $32.3 million. We expect to incur net operating losses and negative
cash flows for the foreseeable future. We will incur direct expenses associated
with the further development and marketing of our existing products and with new
product development. Our success depends on our ability to increase revenues to
offset expenses. We may not be able to generate sufficient revenues to offset
these expenses or to achieve profitability. If we do achieve profitability, we
may not sustain or increase profitability on a quarterly or annual basis in the
future.

THE PROPRIETARY TECHNOLOGY WE OWN OR LICENSE MAY BE SUBJECTED TO INFRINGEMENT
CLAIMS OR DISAGREEMENTS WITH THE LICENSOR WHICH COULD BE COSTLY TO RESOLVE.

    The intellectual property we own or license is important to our business. We
could be subject to intellectual property infringement claims as the number of
our competitors grows and the functionality of our applications overlaps with
competitive offerings. These claims, even if not meritorious, could be expensive
to defend and divert our attention from operating our business. If we become
liable to third parties for infringing their intellectual property rights, we
could be required to pay a substantial damage award and to develop noninfringing
technology, obtain a license or cease selling the applications that contain the
infringing intellectual property. We may be unable to develop non-infringing
technology or obtain a license on commercially reasonable terms. In addition, we
may not be able to protect against misappropriation of our intellectual
property. We have no patents, but instead license important technology from the
University of Pennsylvania and the California HealthCare Foundation.
Consequently, infringement claims against the University or the Foundation or
disagreements between the University or the Foundation and us pertaining to our
licensed technology could have a material adverse effect on our operations.
Third parties may infringe upon our intellectual property rights or the rights
we have licensed from the University or the Foundation. We may not detect this
unauthorized use, and we may be unable to enforce our rights.

WE DEPEND ON AN EXCLUSIVE LICENSE WITH THE UNIVERSITY OF PENNSYLVANIA AND AN
EXCLUSIVE LICENSE WITH THE CALIFORNIA HEALTHCARE FOUNDATION FOR SOME OF OUR
TECHNOLOGY, AND THE LOSS OF THESE LICENSES WOULD IMPAIR OUR ABILITY TO DEVELOP
OUR BUSINESS.

    Our ability to use our technology and compete effectively in our industry
would be impaired if our exclusive license agreements with the University of
Pennsylvania or the California HealthCare Foundation were terminated. Under
these license agreements, we are required to make royalty payments to the
University and the Foundation, respectively, based on a percentage of the fees
we earn through the sublicensing and servicing of the technology and information
received from the University or the Foundation, as applicable, under the
relevant license agreement. In order to maintain the exclusivity of our license
with the University, we are required to pay a minimum of $75,000 per year in
royalties. In order to maintain exclusivity of our license with the Foundation,
we are required to pay a minimum level of $25,000, $41,250, $57,500, $73,750 and
$90,000 per year in royalties for the year 2001, 2002, 2003, 2004 and 2005 and
each year after 2005, respectively. If we do not make these minimum royalty
payments, the University and the Foundation, respectively, may terminate the
exclusive status of our license under the respective agreement, and, in effect,
license the technology to our competitors. In addition, under the license
agreement with the University, the University retains the right, after
consultation and negotiation with us, to publish a description of the technology
without our consent, whether or not any intellectual property protection on this
technology has been filed. If the University or the Foundation were to license
the technology to our competitors or the University were to publish the
technology, our revenues may decrease significantly and we may not be able to
develop or maintain customer and strategic relationships. In addition, if we pay
the University less than $20,000 in royalties,

                                       28

the University may terminate our license entirely. In the event that the
University or the Foundation chose not to license the technology to us at all,
we may not be able to develop similar alternative technology or negotiate a new
license agreement with another licensor. If we were not able to develop
alternative technology or acquire a new license, we may not be able to maintain
our business operations.

WE COULD BE LIABLE FOR INFORMATION RETRIEVED FROM OUR WEB SITES AND INCUR
SIGNIFICANT COSTS FROM RESULTING CLAIMS.

    We may be subject to third-party claims for defamation, negligence,
copyright or trademark infringement or other theories based on the nature and
content of the information we supply to our customers through our Internet-based
applications. These types of claims have been brought, sometimes successfully,
against online services in the past. We could be subject to liability with
respect to content that may be accessible through our Web site or third-party
Web sites linked from our Web site. For example, claims could be made against us
if a customer relies on health care information accessed through our Web site to
their detriment. Even if claims do not result in liability to us, we could incur
significant costs in investigating and defending against them and in
implementing measures to reduce our exposure to any possible liability. Our
insurance may not cover potential claims of this type or may not be adequate to
cover all costs incurred in defense of potential claims or to indemnify us for
all liability that may be imposed.

WE MAY EXPERIENCE SYSTEM FAILURES WHICH COULD INTERRUPT OUR SERVICE AND DAMAGE
OUR CUSTOMER RELATIONSHIPS.

    We have experienced periodic system interruptions in the past, and may in
the future. Our experience has been that interruptions in any month are seldom
more than a few hours. However, any significant interruption in our services or
degradation in response time could result in a loss of potential or existing
customers or strategic partners and, if sustained or repeated, could reduce the
attractiveness of our products to customers and partners. Although we maintain
insurance for our business, it may not be adequate to compensate us for all
losses that may occur or to reimburse costs associated with business
interruptions. We currently operate our application service provider system and
components in a single service location.

THE HEALTH CARE INDUSTRY MAY NOT ACCEPT OUR SOLUTIONS OR BUY OUR PRODUCTS WHICH
WOULD ADVERSELY AFFECT OUR FINANCIAL RESULTS.

    We must attract a significant number of customers throughout the health care
industry or our financial results will be adversely affected. To date, the
health care industry has been resistant to adopting new information technology
solutions. We believe that complexities in the nature of health care data that
we process and analyze have hindered the development and acceptance of
information technology solutions by the industry. Conversion from traditional
methods to electronic information exchange may not occur as rapidly as we
anticipate. Even if the conversion does occur as rapidly as we expect, health
care industry participants may use applications and services offered by others.

    We believe that we must gain significant market share with our applications
and services before our competitors introduce alternative products, applications
or services with features similar to our current or proposed offerings. Our
business plan is based on our belief that the value and market appeal of our
solution will grow as the number of participants and the scope of services
available on our platform increases. In addition, we expect to generate a
significant portion of our revenue from subscription and transaction-based fees
based on patient admissions and encounters. Consequently, any significant
shortfall in the number of subscribers or transactions occurring over our
platform would adversely affect our financial results.

                                       29

OUR QUARTERLY FINANCIAL RESULTS MAY FLUCTUATE SIGNIFICANTLY, WHICH COULD
ADVERSELY AFFECT THE PRICE OF OUR STOCK.

    We expect quarterly revenues, expenses and operating results to fluctuate
significantly in the future. These fluctuations may cause our stock price to
decline. These fluctuations may result from a variety of factors, some of which
are outside of our control. These factors include:

    - expansion or contraction of our customer base;

    - the amount and timing of costs related to product development and
      marketing efforts or other initiatives;

    - the timing of our introduction of new products and the market acceptance
      of those products;

    - the timing of contracts with strategic partners and other parties;

    - the level of acceptance of the Internet by the health care industry; and

    - technical difficulties, system downtime, undetected software errors and
      other problems affecting our products or the Internet generally.

    We expect to increase activities and spending in substantially all of our
operational areas. We base our expense levels in part upon our expectations
concerning future revenue and these expense levels are relatively fixed in the
short-term. If we have lower revenue, we may not be able to reduce our spending
in the short-term in response. These factors may prevent us from meeting the
earnings estimates of securities analysts or investors and our stock price could
suffer.

BECAUSE OUR REVENUES ARE DEPENDENT ON A LIMITED NUMBER OF PRODUCT LINES, THE
FAILURE OF ANY ONE OF THESE PRODUCT LINES WOULD SIGNIFICANTLY DECREASE OUR
REVENUES.

    We currently derive our revenue from our Care Management System, Care Data
Exchange and Lifecycle Decision System Internet-based applications. Because our
revenues are dependent on only a few product lines, the failure of any one of
them to achieve market acceptance would significantly decrease our revenue. As
our customers' needs change, our existing suite of applications may become
inefficient or obsolete and will likely require modifications or improvements.
The addition of new products or services will also require us to continually
improve the technology underlying our applications. These requirements could be
significant, and we may be unable to meet them or may incur unanticipated
product development expenses or delays. If we fail to respond quickly and
efficiently to our customers' needs, or if our new applications and product
offerings do not achieve market acceptance, the market for our products would
likely decline.

    Our business will suffer if we do not expand the breadth of our applications
quickly. We currently offer a limited number of applications on our platform and
our future success depends on quickly introducing new applications to expand the
utility of our products to our existing customer base and generate new
customers. We are developing enhancements to our systems to permit access to
some of our applications by physicians and consumers. We have recently
introduced applications for use by the pharmaceutical industry, which
constitutes a new customer base for us. Each of our applications must integrate
with our computer systems and platform. Developing these applications will be
expensive and time consuming. Even if we are successful, these applications may
never achieve market acceptance.

TERMINATION OF ONE OR MORE OF OUR SIGNIFICANT CONTRACTS WOULD CAUSE A
SIGNIFICANT DECLINE IN OUR REVENUE.

    We currently generate much of our revenue from a limited number of
contractual relationships. During the years ended December 31, 2000 and 1999, we
generated 20% and 21% of our revenue from our development partner, California
HealthCare Foundation. During the year ended December 31,

                                       30

1999, we generated 11% of our revenue from our largest customer, Providence
Health System. Termination of either of these contractual relationships would
significantly decrease our revenue and have a material adverse effect on our
operations. These entities may terminate their contracts for cause or upon
expiration of their agreements in 2003 and 2002, respectively. In addition, one
of our customers, Health Net, Inc., accounted for 37% of our revenue in 1998.

FAILURE TO MANAGE OUR GROWTH WOULD ADVERSELY AFFECT OUR OPERATIONS.

    Our growth has placed significant demands on all aspects of our business,
including our administrative, technical and financial personnel and systems. We
expect future growth which may further strain our management, financial and
other resources. Our systems, procedures, controls and existing space may not
adequately support expansion of our operations. Our future operating results
will substantially depend on the ability of our officers and key employees to
manage changing business conditions and to implement and improve our technical,
administrative, financial control and reporting systems. Failure to respond to
and manage changing business conditions and continued growth could materially
and adversely affect the quality of our services, our ability to retain key
personnel and our results of operations.

WE FACE INTENSE COMPETITION AND MAY BE UNABLE TO COMPETE SUCCESSFULLY WHICH
WOULD ADVERSELY EFFECT OUR FINANCIAL RESULTS.

    The market for Internet services and products is relatively new, intensely
competitive and rapidly changing. Since the Internet's commercialization in the
early 1990's, the number of Web sites on the Internet competing for users'
attention has proliferated with no substantial barriers to entry, and we expect
that competition will continue to intensify. Any pricing pressures, reduced
margins or loss of market share resulting from our failure to compete
effectively would materially and adversely affect our financial results.

    We expect competition in our markets to increase significantly as new
companies enter the market and current competitors expand their product lines
and services. Many of these potential competitors are likely to enjoy
substantial competitive advantages, including:

    - greater resources that can be devoted to the development, promotion and
      sale of their services;

    - longer operating histories;

    - greater financial, technical and marketing resources;

    - greater name recognition; and

    - larger customer bases.

THE LOSS OF ANY OF OUR KEY PERSONNEL COULD ADVERSELY AFFECT OUR OPERATIONS.

    Our future success depends, in significant part, upon the continued service
of our senior management and other key personnel. The loss of the services of
David J. Brailer, our Chief Executive Officer, Ronald A. Paulus, our President,
or one or more of our other executive officers or key employees could have a
material adverse effect on our operations. Our future success also depends on
our ability to attract and retain highly qualified technical, sales, customer
service and managerial personnel. Competition for qualified personnel is
intense, and we may not be able to attract or retain a sufficient number of
highly qualified employees in the future. Failure to hire and retain personnel
in key positions could materially and adversely affect our operations and,
consequently, our financial results.

                                       31

OUR FAILURE TO DEVELOP STRATEGIC RELATIONSHIPS COULD ADVERSELY AFFECT OUR
ABILITY TO DEVELOP NEW PRODUCTS.

    If we fail to form new strategic alliances with industry partners, fail to
maintain existing alliances or if we form alliances with partners which do not
perform well, we will have difficulty gaining acceptance of our products.

    Our development of new and expanded applications for our products will be
enhanced by forming strategic alliances with industry partners. While we believe
that we will form these alliances, we have not yet negotiated many of these
strategic alliances and there is no guarantee that we can consummate these
alliances on commercially reasonable terms.

    To be successful, we must establish and maintain strategic relationships
with leaders in a number of health care industry segments. Strategic
relationships are critical to our success because we believe that these
relationships will enable us to:

    - extend the reach of our applications and services to the various
      participants in the health care industry;

    - obtain specialized health care expertise;

    - develop and deploy new applications;

    - further enhance CareScience brands; and

    - generate revenue.

    Entering into strategic relationships is complicated because some of our
future partners may decide to compete with us. In addition, we may not be able
to establish relationships with key participants in the health care industry if
we have established relationships with competitors of these key participants.
Consequently, it is important that our customers and partners perceive us as
independent of any particular customer or partner. Any substantial relationship
which we have, or develop, with a partner or customer could adversely impact
that perception of independence and make it difficult to enter into strategic
relationships or sell our products to other customers. Most of our revenue is
generated by a small number of significant contracts, which could affect the
perception of our independence; however, we have not experienced any
difficulties in forming strategic relationships in the past for this reason.
Moreover, many potential partners may resist working with us until we have
successfully introduced our applications and services and our applications and
services have achieved market acceptance.

    Once we have established strategic relationships, we will depend on our
partners' abilities to generate increased acceptance and use of our platform,
applications and services. We have limited experience in establishing and
maintaining strategic relationships with health care industry participants. If,
in the future, we lose any strategic relationships or fail to establish
additional relationships, or if our strategic partners fail to actively pursue
additional business relationships and partnerships, we would not be able to
execute our business plans and our business would suffer significantly. We may
not experience increased use of our platform, applications and services even if
we establish and maintain these strategic relationships.

                                       32

OUR FAILURE TO USE NEW TECHNOLOGIES EFFECTIVELY OR TO ADAPT EMERGING INDUSTRY
STANDARDS WOULD ADVERSELY AFFECT OUR ABILITY TO COMPETE.

    To be competitive, we must license leading technologies, enhance our
existing services and content, develop new technologies that address the
increasingly sophisticated and varied needs of health care professionals and
consumers and respond to technological advances and emerging industry standards
and practices on a timely and cost-effective basis. We may not be successful in
using new technologies effectively or adapting our Internet-based applications
and proprietary or licensed technology to user requirements or emerging industry
standards, because those new technologies may not easily integrate with our
existing platform. In addition, we may be unable to implement or adapt new
technologies in a cost-effective manner.

OUR FAILURE TO ADAPT OUR TECHNOLOGY TO OUR CUSTOMERS' NEEDS OR TO HANDLE HIGH
LEVELS OF CUSTOMER ACTIVITY WOULD ADVERSELY AFFECT OUR ABILITY TO INCREASE
REVENUE.

    Our ability to increase revenue in the future will be adversely affected if
our technology is not able to handle high levels of customer activity on our Web
site or if our technology fails to meet our customers' performance standards.

    So far, we have processed a limited number and variety of transactions using
our technology. Similarly, a limited number of health care participants use our
products. We anticipate substantial increased demands on our system as our
business and applications expand. Our systems may not accommodate increased use
while maintaining acceptable performance. We must continue to expand and adapt
our network infrastructure to accommodate additional users, increased
transaction volumes and changing customer requirements. This expansion and
adaptation will be expensive and may divert our attention from other activities.

    Our user agreements with our customers generally contain only limited
performance standards. However, our customers do have performance expectations
and if we fail to meet these expectations, our customers could become
dissatisfied and terminate their agreements with us. The loss of some of our
user agreements could significantly impact our financial results. We may be
unable to expand or adapt our network infrastructure to meet additional demand
or our customers' changing needs on a timely basis and at a commercially
reasonable cost, or at all.

FAILURE BY OUR SERVICE PROVIDERS COULD INTERRUPT OUR BUSINESS AND DAMAGE OUR
CUSTOMER RELATIONSHIPS.

    Our service providers enable us to connect to the Internet. Any problems
with these or other services that result in interruptions of our services or a
failure of our services to function as desired could cause customer complaints
and attrition and could materially and adversely affect our operations. We may
have no means of replacing these services or, in the case of services which we
are obligated to use exclusively, we may be prohibited from replacing these
services, on a timely basis or at all, if those services are inadequate or in
the event of a service interruption or failure. To operate without interruption,
our service and content providers must guard against:

    - damage from fire, power loss and other natural disasters;

    - communications failures;

    - software and hardware errors, failures or crashes;

    - security breaches, computer viruses and similar disruptive problems; and

    - other potential interruptions.

    Interruptions may occur and any material interruptions could adversely
impact our operations and our relationship with our customers.

                                       33

WE MAY NEED TO OBTAIN ADDITIONAL CAPITAL AND FAILURE TO DO SO MAY LIMIT OUR
GROWTH.

    We expect that the available cash and investment balances at December 31,
2000 will be sufficient to meet our requirements for at least the next 12
months. However, we may need to raise additional financing to support expansion,
develop new or enhanced applications and services, respond to competitive
pressures, acquire complementary businesses or technologies or take advantage of
unanticipated opportunities. Failure to raise additional capital, if needed,
will adversely effect our operations and stock price. At the time we need
additional financing, the state of our operations or market conditions generally
may not be favorable, and we may be unable to raise any additional amounts on
reasonable terms, if at all, when they are needed. We may need to raise
additional funds by selling debt or equity securities, by entering into
strategic relationships or through other arrangements.

    In addition, if we sell additional equity securities, your percentage
ownership in us will decrease. If we sell debt securities, the interest payments
we would have to make to the holders of those securities would reduce our
earnings.

OUR OFFICERS, DIRECTORS AND AFFILIATED ENTITIES HAVE SIGNIFICANT CONTROL OVER US
AND THEIR INTERESTS MAY DIFFER FROM YOURS.

    Our directors and management beneficially own or control approximately 45.9%
of our common stock. If these people act together, they will be able to
significantly influence our management, affairs and all matters requiring
shareholder approval. This concentration of ownership may have the effect of
delaying, deferring or preventing an acquisition of us and may adversely affect
the market price of our common stock.

                         RISKS RELATED TO OUR INDUSTRY

HEALTH INFORMATION IS SUBJECT TO POTENTIAL GOVERNMENT REGULATION AND LEGAL
UNCERTAINTIES AND CHANGES MAY REQUIRE US TO ALTER OUR BUSINESS.

    Our business is subject to potential government regulation. Existing as well
as new laws and regulations could affect how we do business and materially and
adversely affect our financial results. There are currently few laws or
regulations that specifically regulate communications or commerce on the
Internet. However, laws and regulations may be adopted with respect to the
Internet or other online services covering issues such as:

    - user privacy;

    - pricing;

    - content;

    - copyrights;

    - distribution; and

    - characteristics and quality of products and services.

    Internet user privacy has become an issue both in the United States and
abroad. Current United States privacy law consists of a few disparate statutes
directed at specific industries that collect personal data, none of which
specifically covers the collection of personal information online. The United
States or foreign nations may adopt legislation purporting to protect the
privacy of personal information. Any privacy legislation could affect the way in
which we are allowed to conduct our business, especially those aspects that
involve the collection or use of personal information, and could have a material
adverse effect on our business. Moreover, it may take years to determine the
extent to which existing

                                       34

laws governing issues such as property ownership, libel, negligence and personal
privacy are applicable to the Internet.

    Currently, our operations are not regulated by any health care agency.
However, with regard to the electronic storage, transmission and communication
of health care information over the Internet, the Health Insurance Portability
and Accountability Act of 1996 directed the U.S. Department of Health and Human
Services to develop and require the use of standards for electronic
transactions, unique identifiers, data security, privacy of individually
identifiable health information and other provisions. Regulations implementing
these standards are in various phases of development. The final regulation
setting standards for electronic transactions and code sets was promulgated on
August 17, 2000. As discussed above, the final regulation setting privacy
standards for protected health information was promulgated on December 28, 2000
and will be effective on April 14, 2001. The other regulations required by the
Health Insurance Portability and Accountability Act of 1996 have not yet been
promulgated as final rules. It will be necessary for our technology platform and
for the applications that we provide to be in compliance with the final privacy
regulation by April 14, 2003. These regulations define specified information
about an individual as protected health information and set forth the steps that
persons storing or transmitting the information must take to ensure its
confidentiality. Our internal procedures and policies for handling of
confidential information, as well as our contractual relationships with others
with whom we share information, will also have to comply with these regulations.
We do not expect to significantly modify our products or business operations or
materially increase our expenses in response to current regulations. However,
the Health Insurance Portability and Accountability Act of 1996 does not prevent
states from implementing more stringent rules or regulations.

    Furthermore, several telecommunications carriers are seeking to have
telecommunications over the Internet regulated by the Federal Communications
Commission in the same manner as other telecommunications services. Because the
growing popularity and use of the Internet has burdened the existing
telecommunications infrastructure in many areas, local exchange carriers have
petitioned the Federal Communications Commission to regulate Internet service
providers and online service providers in a manner similar to long distance
telephone carriers and to impose access fees on the Internet service providers
and online service providers.

CHANGES IN THE HEALTH CARE INDUSTRY COULD ADVERSELY AFFECT OUR OPERATIONS.

    The health care industry is highly regulated and is subject to changing
political, economic and regulatory influences. These factors affect the
purchasing practices and operation of health care organizations. Changes in
current health care financing and reimbursement systems could cause us to make
unplanned changes to our applications or services, or result in delays or
cancellations of orders or in the revocation of endorsement of our applications
and services by health care participants. Federal and state legislatures have
periodically considered programs to reform or amend the United States health
care system at both the federal and state level. These programs may contain
proposals to increase governmental involvement in health care, lower
reimbursement rates or otherwise change the environment in which health care
industry participants operate. Health care industry participants may respond by
reducing their investments or postponing investment decisions, including
investments in our applications and services.

OUR BUSINESS WILL SUFFER IF COMMERCIAL USERS DO NOT ACCEPT INTERNET SOLUTIONS.

    Our business model depends on the adoption of Internet solutions by
commercial users. Our business could suffer dramatically if Internet solutions
are not accepted or not perceived to be effective. The Internet may not prove to
be a viable commercial marketplace.

                                       35

    We expect Internet use to grow in number of users and volume of traffic. The
Internet infrastructure may be unable to support the demands placed on it by
this continued growth.

OUR INDUSTRY IS EVOLVING AND WE MAY NOT ADAPT SUCCESSFULLY.

    The new and rapidly evolving Internet market may cause us to incur
substantial costs in responding to changes in that market or, if we fail to
respond to such changes, cause our revenues to decline as our customers switch
to newer, better technology. Advances in software technology occur frequently,
and we may not respond rapidly enough to the introduction of better software to
maintain our customer base in the future. We will not be successful in the
Internet market, unless, among other things, we:

    - increase awareness of our CareScience brands and continue to develop
      customer loyalty;

    - provide useful health care analysis services to subscribers at attractive
      prices;

    - respond to competitive and technological developments; and

    - build an operations structure to support our business.

                       RISKS RELATING TO OUR COMMON STOCK

OUR COMMON STOCK PRICE MAY BE VOLATILE.

    Our stock price has declined since our initial public offering due to a
number of factors, including:

    - actual or anticipated quarterly variations in our operating results;

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

    - announcements of technological innovations;

    - announcements relating to strategic relationships;

    - customer relationship developments; and

    - conditions affecting the Internet or health care industries, in general.

    The trading price of our common stock may be volatile. The stock market in
general, and the market for technology and Internet-related companies in
particular, has experienced extreme volatility that often has been unrelated to
the operating performance of particular companies. These broad market and
industry fluctuations may adversely affect the trading price of our common
stock, regardless of our actual operating performance.

    In the past, securities class action litigation has often been instituted
following periods of volatility in the market price of a company's securities.
If this were to happen to us, that litigation could be expensive and would
divert management's attention.

FUTURE SALES OF SHARES COULD ADVERSELY AFFECT OUR STOCK PRICE.

    The market price for our common stock could fall dramatically if our
shareholders sell large amounts of our common stock in the public market. These
sales, or the possibility that these sales may occur, could make it more
difficult for us to sell equity or equity-related securities in the future.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    Our cash equivalents, short-term investments and capital lease obligations
are at fixed interest rates and therefore the fair market value of these
instruments is affected by changes in market interest

                                       36

rates. As of December 31, 2000 all of our cash equivalents and short-term
investments matured or were redeemed within 6 months and we had the ability to
immediately liquidate our investments. Therefore, we believe that we are exposed
to immaterial levels of market risk.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Directors:

    We have audited the accompanying consolidated balance sheets of
CareScience, Inc. (a Pennsylvania corporation) and subsidiaries as of
December 31, 1999 and 2000, and the related consolidated statements of
operations, mandatorily redeemable preferred stock and shareholders' equity
(deficit) and cash flows for each of the three years in the period ended
December 31, 2000. These consolidated financial statements and the schedule
referred to below are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements and schedule based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States. 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
CareScience, Inc. and subsidiaries as of December 31, 1999 and 2000, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 2000, in conformity with accounting principles
generally accepted in the United States.

    Our audits were made for the purpose of forming an opinion on the basic
consolidated financial statements taken as a whole. The information included in
Schedule II is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not a required part of the basic consolidated
financial statements. This schedule has been subjected to the auditing
procedures applied in our audits of the basic consolidated financial statements
and, in our opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic consolidated financial
statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BACKGROUND:

    CareScience, Inc. (formerly Care Management Science Corporation) (the
"Company") provides Internet-based tools designed to improve the quality and
efficiency of health care. The Company's products use its proprietary clinical
algorithms and data collection and storage technologies to perform complex
clinical analyses. The Company's customers use its products to identify clinical
inefficiencies and medical errors and monitor the results of implemented
solutions. Additionally, the Company facilitates the real-time exchange of
clinical information over the Internet among local health care constituents.

    The Company incurred losses in the current and prior year, and anticipates
incurring additional losses through 2001 as it expands its customer base and
product offerings. The Company's management believes that cash on hand at
December 31, 2000 and cash generated from revenues in 2001 will be sufficient to
sustain operations at least into 2002.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

PRINCIPLES OF CONSOLIDATION

    The accompanying consolidated financial statements include the accounts of
CareScience, Inc. and its subsidiary. All significant intercompany transactions
and balances have been eliminated.

CASH AND CASH EQUIVALENTS AND AVAILABLE-FOR-SALE SECURITIES

    The Company invests excess cash in highly liquid investment-grade marketable
securities including corporate commercial paper and U.S. government agency
bonds. For financial reporting purposes, the Company considers all highly liquid
investment instruments purchased with an original maturity of three months or
less to be cash equivalents. All investment instruments with maturities greater
than three months are available for use in current operations and accordingly
are classified as current assets. All investments are considered
available-for-sale and, accordingly, unrealized gains and losses are included in
a separate component of shareholders' equity.

    As of December 31, 2000 cash and cash equivalents and short-term investments
at cost and fair market value consisted of the following:



                                                           GROSS         FAIR
                                            ORIGINAL     UNREALIZED     MARKET
                                              COST         GAINS         VALUE
                                           -----------   ----------   -----------

Short-term investments...................    3,000,000      1,770       3,001,770
                                           -----------     ------     -----------
                                           $29,702,096     $1,770     $29,703,866
                                           ===========     ======     ===========


    Short-term investments consist of one debt instrument maturing November 6,
2002.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Major additions and improvements
are capitalized, while maintenance and repairs that do not improve or extend the
life of assets are charged to expense as incurred.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    Depreciation and amortization are provided using the straight-line method
over the following estimated useful lives:


                                                           
Computer equipment..........................................  3 years
Office equipment............................................  5 years
Furniture and fixtures......................................  7 years


    Depreciation and amortization expense was $592,705, $574,903, and $856,824
for the years ended December 31, 1998, 1999 and 2000, respectively.

RESEARCH AND DEVELOPMENT

    Research and development costs are charged to expense as incurred.

SOFTWARE DEVELOPMENT COSTS

    In conjunction with the development of its software products, the Company
incurs software development costs. Statement of Financial Accounting Standards
("SFAS") No. 86, "Accounting for the Costs of Computer Software to Be Sold,
Leased, or Otherwise Marketed," requires the capitalization of certain software
development costs subsequent to the establishment of technological feasibility.
The Company has determined that technological feasibility for its software
products is generally achieved upon completion of a working model. As of
December 31, 2000, no costs are capitalized pursuant to SFAS No. 86, since
software development costs are not significant after the completion of a working
model. These development costs are included in research and development expenses
in the accompanying statements of operations.

    In conjunction with the development of its websites, the Company incurs
software development costs. On January 1, 1999, the Company adopted the
provisions of Statement of Position ("SOP") 98-1 "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use". Prior to 1999, the
Company had expensed all development costs related to its websites. In 1999 and
2000, the Company incurred costs related to the development of information
sharing technologies for health care providers and pharmaceutical and biotech
companies. These costs are being funded by third parties, and therefore, have
not been capitalized. All other costs incurred in 1999 and 2000, were related to
maintenance of the websites and have been charged to expense as incurred.

REVENUE RECOGNITION

    The Company's product agreements, which typically cover an initial period of
three-to-five years and are fixed priced, provide to customers, among other
things, a license to use software stored on the Company's system, project
management services, data management services, data storage and computer server
maintenance and software support and maintenance. Revenues under these contracts
are recognized ratably over the contract period. Any additional consulting fees
are recognized as the service is delivered.

    The Company's development agreements, with periods ranging from
three-to-five years, provide for customer funding for the development of new
products. In accordance with SAB 101, the Company is

                                      F-9

                               CARESCIENCE, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
treating revenue on these agreements as a single element contract and is
recognizing total revenue on a cost-to-cost basis over the entire agreement
period.

IMPAIRMENT OF LONG-LIVED ASSETS

    The Company continually evaluates whether events and circumstances have
occurred that indicate that the remaining estimated useful life of long-lived
assets may warrant revision or that the remaining balance may not be
recoverable. When factors indicate that such assets should be evaluated for
possible impairment, the Company uses an estimate of the related undiscounted
cash flow in measuring whether the asset is recoverable. Management believes
that no revision to the remaining useful lives or write-down of such assets is
required.

INCOME TAXES

    The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes," under which deferred taxes are required to be
classified based on financial statement classification of the related assets and
liabilities which give rise to the temporary differences. Deferred taxes result
from temporary differences between the financial statement carrying amounts and
the tax basis of assets and liabilities.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The fair value of a financial instrument represents the amount at which the
instrument could be exchanged in a current transaction between willing parties,
other than in a forced sale or liquidation. Differences can arise between the
fair value and carrying amount of financial instruments that are recognized at
historical cost. The Company's financial instruments consist primarily of cash
and cash equivalents, short-term investments, accounts receivable, accounts
payable and accrued expenses.

    The carrying amounts of cash and cash equivalents, short-term investments,
accounts receivable, accounts payable and accrued expenses approximate fair
value due to the short maturity of these instruments.

MAJOR CUSTOMERS

    The Company's operations are conducted in one business segment and sales are
primarily made to health care payors and providers. The Company had one, two,
and one customers for the years ended December 31, 1998, 1999 and 2000,
respectively, which accounted for 37%, 32%, and 20% of total revenues.

    The Company had three and two customers as of December 31, 1999 and 2000,
respectively, which accounted for 37% and 29% of total accounts receivable.

BUSINESS AND CREDIT RISK CONCENTRATION

    Financial instruments which potentially subject the Company to
concentrations of credit risk are cash and cash equivalents, short-term
investments and accounts receivable. The Company limits its credit risk
associated with cash and cash equivalents and short-term investments by placing
its investments in highly liquid funds.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
USE OF ESTIMATES

    The preparation of financial statements in conformity with accounting
principles generally accepted in these United States 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 amounts could differ from those estimates.

SUPPLEMENTAL CASH FLOW INFORMATION

    The Company paid interest of $98,704, $95,324 and $89,682 for the years
ended December 31, 1998, 1999 and 2000, respectively.

    The Company financed $338,801, $223,794 and $252,401 of property and
equipment purchases with capital leases for the years ended December 31, 1998,
1999 and 2000, respectively.

    In December 1998, the Company sold 2,366,947 shares of Series C Convertible
Preferred stock (see Note 8). In connection with the sale, the Company converted
notes payable including accrued interest to a Preferred Shareholder into
Mandatorily Redeemable Series G Preferred stock which resulted in a non-cash
transaction of $4,272,083 (see Note 7). In addition, the Company recorded a
non-cash charge of $8,307, $401,244 and $253,731 for the accretion of dividends
relating to the Mandatorily Redeemable Series G Preferred stock during the years
ended December 31, 1998, 1999 and 2000, respectively.

COMPREHENSIVE INCOME

    Effective July 2000, the Company adopted Statement of Financial Accounting
Standards No. 130(SFAS 130), "Reporting Comprehensive Income" which requires the
Company to report and display certain information related to comprehensive
income. Comprehensive income includes net income and other comprehensive income.
Other comprehensive income is classified separately as unrealized gains on
available-for-sale securities.

RECENT ACCOUNTING PRONOUNCEMENTS

    In December 1999, the Securities and Exchange Commission "SEC" issued Staff
Accounting Bulletin (SAB) No. 101, "Revenue Recognition in Financial
Statements." SAB 101 expresses the views of the SEC staff in applying generally
accepted accounting principles to revenue transactions. The Company's financial
statements and related disclosures conform to the views of the SEC staff as
documented in SAB 101.

3. NET LOSS PER SHARE:

    Net loss per share is calculated utilizing the principles of SFAS No. 128,
"Earnings per Share" ("EPS"). Basic EPS excludes potentially dilutive securities
and is computed by dividing net income available to common shareholders by the
weighted-average number of common shares outstanding for the period. Diluted EPS
is computed assuming the conversion or exercise of all dilutive securities such
as preferred stock, options and warrants.

                                      F-11

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

3. NET LOSS PER SHARE: (CONTINUED)
    Under SFAS No. 128, the Company's granting of certain stock options,
warrants and convertible preferred stock resulted in potential dilution of basic
EPS. The number of incremental shares from the assumed exercise of stock options
and warrants is calculated applying the treasury stock method. Stock options,
warrants and Preferred stock convertible into common shares were excluded from
the calculations as they were anti-dilutive due to the net loss in all periods
presented.

    Unaudited pro forma basic and diluted EPS have been included on the face of
the statements of operations for the years ended December 31, 1998, 1999 and
2000 to show the net loss per common share before the effect of the preference
distribution on preferred stock and the accretion of the redemption premium on
preferred stock.

4. INCOME TAXES:

    The Company incurred operating losses and generated a significant
accumulated deficit through December 31, 2000, therefore, no tax provisions have
been recorded. As of December 31, 2000 the Company had federal net operating
loss carryforwards of approximately $26.0 million which expire from 2010 through
2020. At December 31, 1999 and 2000 a valuation allowance was recorded for 100%
of the Company's deferred tax asset as realization of the tax benefit was not
considered more likely than not.

    The deferred tax effect of temporary differences giving rise to the
Company's deferred tax assets consist of the following components:



                                                                   DECEMBER 31,

Note 8), the Company converted notes payable due to a shareholder with initial
principal amounts of $2,684,675 and $1,000,000, respectively, plus all accrued
interest into 1,560,000 shares of Series G Mandatorily Redeemable Preferred
stock (Series G Preferred). This Series G Preferred required mandatory

PREFERRED STOCK

    On December 24, 1998, the Company sold 2,366,947 shares of Series C
Convertible Preferred stock for $6,175,000 to new investors and converted
Series A and B Preferred stock into Series D and E Preferred stock respectively.

    The Series C, D and E Preferred require a dividend of 8% per year based upon
their respective liquidation value when and if declared by the Company, and are
convertible into Common stock, at an initial conversion rate of one share of
Common stock for each share of Preferred. Upon conversion of the Series C, D and
E Preferred stock, if certain minimum return requirements, as defined, were not
met, the holders of the Series C, D and E Preferred were entitled to receive a
dividend equal to that which would have been received upon liquidation.
Simultaneously with the conversion of Series C Preferred into Common stock, each
Series C shareholder was to receive one share of Series F Redeemable Preferred
stock (Series F Preferred) if certain minimum return requirements, as defined,

dividend of 8% per year based on their liquidation value or upon redemption. The
Series F Preferred had an assigned liquidation value of $4.2 million (if all
Series C Preferred shares were converted).

    Prior to the sale of the Series C Preferred, the Company entered into two
agreements with a Preferred shareholder which provided bridge financing of
$500,000, in aggregate. The loan bore interest of 8.75% and was repaid out of
the proceeds of the sale of the Series C Preferred.

EQUITY COMPENSATION PLANS

    The Company's 1995 Equity Compensation Plan (the "Plan") permits the
granting of incentive stock options, nonqualified stock options, stock
appreciation rights and restricted stock. The Company has authorized the
issuance of up to 2,065,038 shares of Common stock to satisfy grants under the
Plan. At December 31, 2000, there were 701,495 shares reserved under the Plan
available for grant. A committee of the Board of Directors (the "Committee")
administers the Plan and determines the terms of the grants.

    Stock options issued under the Plan generally vest over a four-year period,
25% on each anniversary date. The exercise period is determined by the
Committee, but may not exceed ten years from the date of grant. Each option
entitles the holder to purchase one share of Common stock at the indicated
exercise price.

    In December 1998, the Company adopted the 1998 Time Accelerated Restricted
Stock Option Plan (the "Accelerated Plan"). The Accelerated Plan provides for
the granting of non-qualified stock options to officers, senior management and
employee directors of the Company. The aggregate number of shares of Common
stock the Company may issue under the Accelerated Plan is 483,594 shares. At
December 31, 2000 there were no shares reserved under the Accelerated Plan
available for grant.

    Stock options issued under the Accelerated Plan generally vest upon the
earlier of the attainment of certain performance goals or seven years. The
exercise period is determined by the Committee, but may not exceed ten years
from the date of the grant. Each option entitles the holder to purchase one
share of Common stock at the indicated exercise price.

    The Company accounts for all plans under APB Opinion No. 25, under which
compensation expense is recognized based on the amount by which the fair value
of the underlying common stock exceeds the exercise price of the stock options
on the measurement date. For financial reporting purposes, the Company has
determined that the deemed fair market value on the measurement date for certain
stock options was in excess of the exercise price. This amount has been recorded
as deferred compensation and is being amortized over the vesting period of the
applicable options which range between four and seven years. The Company
recorded deferred compensation of $5,624,839 and $120,683 during the years ended
December 31, 1999 and 2000, respectively, and reversed $154,902 of deferred
compensation in connection with forfeited Common stock options during the year
ended December 31, 2000. The Company recognized $232,517 and $1,347,275 of
compensation expense related to options for the years ended December 31, 1999
and 2000, respectively.
