                                     PART I
 
ITEM 1.  BUSINESS
 
     Medirisk, Inc. (together with its subsidiaries, "Medirisk" or the
"Company") is a provider of proprietary database products, decision-support
software and analytical services to the health care industry. The Company's
products and services enable its customers to make objective comparisons of the
financial costs and clinical outcomes of physician services to customer-specific
and industry benchmarks, assess patient satisfaction with specific managed care
plans, and obtain information concerning the background and credentials of
physicians. These capabilities assist health care industry participants in
measuring the performance of health care payors and providers.
 
     Applications for Medirisk's products include pricing managed care
contracts, evaluating physician fee schedules and utilization of physician
services, comparing provider outcomes and health plan performance, credentialing
and recruiting physicians, developing health care delivery networks, and
marketing health care services. The Company actively sells its products to over
1,000 major customers, including leading health plans, insurers, hospitals,
large multi-specialty physician groups, physician practice management companies,
employers, and pharmaceutical companies, as well as to several hundred smaller
customers, including single-specialty physician groups. Medirisk believes that
it is the leading provider of clinical and financial database products comprised
of physician-oriented content and managed care member satisfaction information
in the United States.
 
     Medirisk built its databases by collecting, standardizing and normalizing
more than three billion health care transaction records. Medirisk's databases
include records submitted by the Company's customers under an ongoing data
collection plan, data generated from the results of periodic proprietary surveys
of health care providers, consumers, managed care plans and other payors, and
data gathered from various regulatory and governmental agencies. Medirisk
believes the long-standing relationships under which it collects data and the
data interpretation methodologies utilized by the Company represent significant
competitive advantages. Medirisk's databases are regularly updated to reflect
changes in the industry and, in the case of its market performance and clinical
performance databases, to take into consideration secondary factors such as co-
morbidity, case mix and demographics. These attributes permit customers to
compare objectively their financial and clinical performance to industry or
customer-specific benchmarks contained in the Company's databases with
specificity and precision.
 
INDUSTRY OVERVIEW
 
     The U.S. health care industry has grown dramatically in recent years.
According to the Health Care Financing Administration ("HCFA"), health care
expenditures have increased from less than $250 billion, or approximately 9% of
the gross domestic product, in 1980 to in excess $1.0 trillion, or approximately
14% of the gross domestic product, in 1996. Payors are responding to escalating
costs by seeking to transfer the financial risk associated with the delivery of
health care to providers under capitated or other managed care arrangements. As
managed care arrangements become increasingly prevalent, both payors and
providers are under intense pressure to deliver health care at the lowest total
cost while ensuring high quality results. To achieve this goal, payors and
providers must understand procedure cost and utilization rates as well as
demonstrate improved outcomes. The evolving impact of managed care has increased
physicians' receptivity to a variety of practice affiliation and employment
structures and, consequently, the need for data that can be used to verify
physician qualifications.
 
     Traditional health care information systems have focused on the
administrative aspects of health care (i.e., accounting, billing, patient
scheduling). Medirisk believes there is an increasing trend toward reimbursement
structures for health care services which require sophisticated financial
information management and a growing awareness that most health care costs are
related to the clinical (rather than administrative) aspects of the delivery of
care. The result has been a growing demand for databases incorporating
financial, clinical and analytical tools that leverage this data in order to
assess managed care contracts, analyze outcomes, evaluate managed care member
satisfaction, verify the qualifications of providers and meet ongoing
<PAGE>   3
 
accreditation requirements. While some payors and providers have recently
adopted new information systems that allow them to capture cost, utilization and
clinical outcomes data regarding their own businesses, they generally have not
been able to use such data effectively. To gain perspective on the marketplace
and to analyze the potential impact of managed care contracts, payors and
providers need benchmark data against which they can compare the data they have
collected regarding their own businesses, as well as information relating to
statistical differences in health care costs and outcomes among urban, suburban
and rural markets. While broad, public-sector data have previously been
available, payors and providers increasingly seek more in-depth, region-specific
health care information, which requires access to both private- and
public-sector data.
 
     The health care information industry is highly fragmented and undergoing
consolidation, as vendors and service providers seek to build market share and
compete more effectively. Many existing health care information businesses have
been created by entrepreneurs who are knowledgeable in the areas of data
products and technology, but these businesses typically lack the sophisticated
marketing organizations, sales effort, capital and general management skills and
processes that are required to generate sustainable revenue expansion. Combined
with the burdens associated with product development and rapid technological
change, these issues pose significant challenges to health care information
companies that lack breadth of management experience, economies of scale and
access to capital. As a result of these factors, many smaller health care
information companies with technologically sophisticated products and a
reputation for quality service have become attractive acquisition candidates for
vendors and service providers seeking to reach critical mass.
 
STRATEGY
 
     Medirisk's objective is to become the leading provider of proprietary
database products, decision-support software and analytical services to payors,
providers, employers, pharmaceutical companies and other health care industry
participants. To attain this objective, Medirisk is pursuing the following
strategy:
 
          Leverage the Company's Existing Customer Base.  Medirisk believes the
     increasing demand for health care information, coupled with its broad
     customer base, provides a substantial opportunity for internal growth. The
     Company has long-standing relationships with its customers and believes it
     has developed a reputation for providing objective, value-added information
     products. The Company intends to leverage these relationships by
     cross-selling additional products and services to existing customers and
     increasing product penetration through sales to other operating units,
     departments or divisions of existing customers.
 
          Emphasize Recurring Revenue.  Medirisk seeks to maximize recurring
     revenue by emphasizing multi-year contracts and contract renewals. A
     substantial portion of Medirisk's revenue is generated by the licensing of
     products on an annual or multi-year basis. The Company believes that its
     high rate of recurring revenue results principally from significant revenue
     enhancements or cost savings achieved by Medirisk's customers when they use
     the Company's products, as well as from the customer's ongoing need for
     current information due to the rapid pace of change within the health care
     industry. The Company's recurring revenue percentage has been in excess of
     70% for each of the last four years.
 
          Develop New Products and Decision-Support Tools.  Medirisk actively
     develops new products, product enhancements and decision-support tools and,
     in 1997, introduced several new products and product enhancements. The
     Company expects to introduce additional new products and product
     enhancements during 1998. Ultimately, the Company intends to
     cross-correlate existing and future databases in an effort to develop
     integrated product offerings. For example, Medirisk believes that by
     linking its market performance, clinical performance and physician
     credentials products, cost and quality can be evaluated together with
     outcomes for specific physicians, thus permitting true management of care
     by allowing customers to compare the financial costs and expected outcomes
     of competing treatment regimens or providers, and to measure health care
     consumer satisfaction.
 
          Acquire and Integrate Complementary Products and Businesses.  Medirisk
     intends to acquire additional companies, products, databases and other
     resources to expand into related areas and to increase market share within
     the Company's existing product lines. Medirisk believes that the
     acquisition
                                        2
<PAGE>   4
 
     of new products and customers creates compelling cross-selling
     opportunities, enhances the development of new products by facilitating
     cross-correlation of existing and acquired products, and provides
     significant operating leverage. See "Acquisitions."
 
ACQUISITIONS
 
     Medirisk believes the selective acquisition of complementary businesses
results in a more rapid expansion of its product line and enables it to leverage
its sales and marketing organization. As a result, Medirisk has invested
significant resources to build the business platform necessary to be a
consolidator in the fragmented health care information services industry. In
1997, Medirisk acquired four companies that provide complementary products and
services. The Company believes the acquisition of these entities created
significant cross-selling opportunities among its respective product offerings,
increased its market share within existing product lines and provided product
and customer expansion opportunities.
 
     As part of a systematic approach to implementing its acquisition strategy,
Medirisk has corporate resources dedicated to identifying, analyzing and
pursuing targeted acquisition candidates. The Company currently is tracking a
database of more than 300 companies, of which approximately 100 meet its primary
acquisition criteria for product type, revenue and customer base. Of primary
interest to Medirisk are: (i) health care information products focused on
benchmark and outcomes data; (ii) software products that assist in data
collection and analysis; (iii) health care consulting firms; and (iv) products
that assist in the delivery and use of Medirisk's databases.
 
     Medirisk believes that its existing infrastructure, in combination with
management's experience in acquiring and integrating new companies and products,
will facilitate the continued successful implementation of its acquisition
strategy.
 
PRODUCTS AND SERVICES
 
     Medirisk provides products and services designed to enable its customers to
measure and assess the performance of health care services in the United States.
At the core of the Company's products and services are several proprietary
databases. The detailed nature of Medirisk's databases provides precise data
that customers can use to address specific decision-making needs and offers the
Company's customers competitive advantages. Medirisk also provides
decision-support software tools that enhance the utility of its database
products, as well as customized analytical services. The Company's flexible

  Market Performance Products
 
     Medirisk's market performance products provide customers with comprehensive
proprietary data and decision support tools for use in analyzing physician fees,
health care utilization patterns and member satisfaction with managed care plans
in the United States. The following is a description of the Company's primary
market performance products:
 
          CareData Reports(TM). CareData Reports are reports that are created
     utilizing information accumulated and analyzed by the Company regarding
     consumer satisfaction with managed health care. Based on this data,
     CareData Reports rank specific health plans. Comparative market analysis is
     available for 26 geographic markets and 170 health plans. To collect data
     used in CareData Reports, the Company conducts health care consumer surveys
     that are sponsored by approximately 400 major employers and measure patient
     satisfaction with approximately 150 aspects of managed health care. The
     Company's CareData Reports product line is utilized by health plans to
     assess their competitive position and quality of care, by employers to
     evaluate health plans and by pharmaceutical companies to target potential
     markets for their products.
 
          MEDIRISK(SM) Physician Fee Database. The Physician Fee Database
     reports reimbursement rates for medical procedures for various types of
     payors and specific geographic markets across the United States. The
     Physician Fee Database provides data concerning reimbursement levels that
     providers are accepting from managed care plans and other payors, rather
     than fees charged by those providers, a distinction critical to an accurate
     understanding of market conditions. Fee data in the Physician Fee Database
     are tracked by the AMA's CPT codes, which define all current medical
     procedures and are segregated into 287 separate market areas in the United
     States (compared to 89 market areas that were tracked by HCFA in 1997).
     Medirisk believes that the Physician Fee Database divides the United States
     into more geographic markets than most competing products, thereby allowing
     customers to make more precise fee decisions. A customer can license data
     for a specific market, state or region or for the entire United States.
 
          MEDIRISK(SM) Procedure Utilization Database. The Procedure Utilization
     Database provides frequently updated utilization data for all medical
     procedures included in the Company's Physician Fee Database. This database
     can be used to model the anticipated utilization of a specific service for
     a certain population profile. The database is offered on a state-specific
     basis and can be adjusted for age and gender.
 
          MEDIRISK(TM) Capitation Manager. Capitation Manager is a
     Windows(R)-based decision-support application that integrates Medirisk's
     Physician Fee Database and Procedure Utilization Database and calculates
     capitation rates based on customer-provided pricing and demographic
     assumptions. Using Capitation Manager, the customer enters the demographic
     profile of a group proposed to be covered in a capitated arrangement, the
     services to be provided and proposed capitated pricing for those services.
     Using these assumptions in combination with the Company's databases,
     Capitation Manager calculates the expected utilization of the services to
     be provided and compares the proposed capitated pricing to managed care,
     fee-for-service, Medicare and other fee benchmarks tracked by the Company
     within a specific market.
 
  Clinical Performance Products
 
     Medirisk offers clinical performance products that enable customers to
measure clinical outcomes across a full range of care within a variety of
medical specialties. Clinical outcomes are generally defined as the change in a
patient's health status as a result of therapy or care delivered by a health
care professional. Clinical outcomes are measured empirically using standard
health status scales to assess the patient prior to the delivery of therapy or
care, while such care is being delivered and after treatment is terminated. The
data included in these products are gathered by Company-certified clinicians,
automated patient information systems and Medirisk's patient interview staff
using the Company's standardized outcomes scales. Comparing customer data with
norms derived from Medirisk's database, Medirisk prepares reports detailing
customers' clinical performance based on a number of independent measures
including patient acuity, medical and functional improvement, resource
utilization, length of stay/duration of treatment, cost of treatment and
 
                                        4
<PAGE>   6
 
patient satisfaction. Medirisk's clinical performance products assist both
payors and providers with (i) measuring and predicting outcomes of treatment
regimens; (ii) making normalized comparisons of facilities and providers; (iii)
establishing benchmarks for clinical quality improvement; (iv) developing
standards for clinical practice; (v) generating analytical reports for
communicating with customers and their constituents; and (vi) substantiating
quality for managed care contracting and accreditation needs.
 
     Medirisk markets its clinical performance products primarily to health care
providers, and its products are currently available to track clinical outcomes
in ambulatory surgery, rehabilitation, orthopaedics, occupational health, pain
management, neurological care, wound care, respiratory care, nutrition and
infection therapy.
 
     In March 1997, Medirisk's clinical performance products were listed on the
Joint Commission on Accreditation of HealthCare Organizations' ("JCAHO") roster
of vendors who have acceptable clinical performance measurement systems to
support ORYX, JCAHO's new accreditation initiative. The ORYX initiative requires
health care organizations to select an outcomes measurement standard from
JCAHO's list of acceptable performance measurement systems in order to receive
JCAHO accreditation. The ORYX initiative currently covers hospitals, long-term
care organizations, integrated delivery networks, health plans and
provider-sponsored organizations.
 
  Physician Credentials Products
 
     Medirisk provides database products, software and outsourced services
designed to enable its customers to access detailed information concerning the
background and credentials of physicians in the United States. The Company's
physician credentials products facilitate its customers' ability to establish or
improve physician recruiting efforts on a cost-effective basis, develop health
care networks and market the provider component of health care services.
Medirisk's physician credentials products also aid hospital and managed care
customers in verifying the credentials of physicians and other providers with
whom they work. Hospitals, managed care organizations and other health care
industry participants are required to verify and periodically re-verify such
credentials in order to maintain accreditation by organizations such as the
National Committee for Quality Assurance ("NCQA") and JCAHO. The Company's
credentials service has successfully completed all 10 of the audits of
credentialing processes conducted by NCQA. The Company's physician database is
comprised in part of physician data from the AMA's Physician MasterFile. All
physician information is further validated and enhanced by personal telephone
interviews with the physicians conducted by members of Medirisk's staff. Current
products include:
 
          Provider Credential Verification Report(TM). The Provider Credential
     Verification Report is a report that provides customers with an efficient
     and cost-effective means to verify electronically the key professional
     credentials of participating health care practitioners using primary source
     data. When joined with the Company's electronic processing of a National
     Practitioner Database and/or Federation of State Medical Boards query, and
     written verification of a practitioner's hospital privileges, malpractice
     insurance coverage and claims history, the Provider Credential Verification
     Report becomes the central component of the Company's credential and
     verification service.
 
          PrimeSource(TM).  PrimeSource is a credential verification database
     provided in CD-ROM format. This database is an accurate, cost-effective way
     to verify a physician's credentials. PrimeSource includes records for the
     following: state licenses and sanctions; Drug Enforcement Agency
     registrations and sanctions; US medical school education records from 1979
     to the present; US residency program training records from 1983 to the
     present; board certifications from the American Board of Medical
     Specialties; Medicare Universal Provider Identification Numbers; and
     Medicare and Medicaid sanctions. PrimeSource is updated quarterly, and
     customers are billed only for the reports they generate.
 
          PracticeMatch(TM).  PracticeMatch is a Windows(R)-based
     decision-support software system that provides in-house physician
     recruiters with on-line access to the Company's physician database. By
     establishing a series of search and selection criteria, customers obtain
     information about physicians who satisfy specified criteria. The customer
     can then print or download the information for use in building in-house
     databases, generating recruiting status reports and tracking recruiting
     expenses associated with
 
                                        5
<PAGE>   7
 
     specific candidates. The PracticeMatch product is constructed from
     proprietary records of approximately 135,000 physicians developed in part
     from data in the AMA's Physician MasterFile.
 
DATA ACQUISITION METHODOLOGY
 
     In designing its products and services, Medirisk emphasizes quality and
ease of use. Medirisk uses proprietary data engineering methodologies to
standardize and interpret data in order to ensure that its products are as
comprehensive, accurate and current as possible. The detailed nature of the
Company's databases provides precise data that customers can use to address
their specific decision-making needs. Furthermore, Medirisk's data engineering
methodologies are designed to ensure that its databases are free of bias. The
resulting objectivity of Medirisk's products and services allows the Company to
market its products to a broad range of health care industry participants and
improves the credibility of its databases as benchmarking tools.
 
     The Company collects data for inclusion in its databases and related
products in a variety of ways, including its customer data collection program
and its regular surveys of managed care organizations, providers, employers and
consumers. To encourage customers to participate in some components of its data
collection program, Medirisk offers price discounts in return for access to
customers' raw claims data and other health care transaction records. Medirisk's
surveys are conducted on a regular basis, with special surveys conducted from
time to time to address new issues and emerging trends. Once the data are
collected, Medirisk's database personnel clean and analyze the data before they
are included in the Company's databases. Medirisk uses proprietary processes to
validate data by standardizing, normalizing and formatting the submitted data
and then applies its database methodologies to segment the data.
 
     Medirisk's databases are regularly updated to reflect changes in the
industry and, in the case of its market performance and clinical performance
databases, to take into consideration secondary factors such as co-morbidity,
case mix and demographics. These attributes permit customers to compare
objectively their financial and clinical performance to industry or
customer-specific benchmarks contained in the Company's databases with
specificity and precision.
 
     Market Performance Products.  The data used in Medirisk's market
performance products have been collected through (i) Medirisk's customer data
collection program, whereby customers provide their medical claims or other
health care transaction data to the Company on a regular basis, (ii) surveys of
more than 1,600 managed care organizations, (iii) purchases of certain data
sets, and (iv) maintenance of a customer-support database. Included in the
Physician Fee Database and Procedure Utilization Database are approximately 3.0
billion private sector transaction records, including actual managed care
transaction data and negotiated fee schedules. While Medirisk's market
performance databases include public-sector data, they focus primarily on
private-sector data derived from transaction data and clinical records
contributed by Medirisk's customers and obtained from other sources. These
private- and public-sector data are not commingled, thus permitting more precise
benchmarking of data relevant to the private health care marketplace. The
Company believes that private-sector data are more useful for comparative
purposes than public-sector data and that Medirisk's comprehensive compilation
of private-sector data represents a competitive advantage for the Company. For
the Company's CareData Reports products, Medirisk conducts annual patient
surveys regarding consumer satisfaction with managed care. These surveys are
sponsored by approximately 400 major employers and measure member satisfaction
with approximately 150 aspects of managed care including satisfaction with
provider panels, pharmacy benefit management and overall health plan design.
 
     Clinical Performance Products.  Medirisk obtains data for its clinical
outcomes databases from its clinical outcomes customers and other
Company-certified sources. To facilitate collection of outcomes measurements,
the Company provides its customers with data-collection tools that are tailored
to the customer's clinical record-keeping environment. Medirisk collects the
data through customer submission, automated patient information systems and
direct patient interviews conducted by the Company's clinical interview staff.
Data collection software or optical scan forms are used to collect data directly
from the clinician in the absence of automated patient systems. To enhance the
reliability and integrity of customer-submitted data, Medirisk will include in
its outcomes database only information received from customer-

affiliated clinicians who are trained and certified by Medirisk in rating

     Physician Credentials Products.  The data included in Medirisk's physician
credentials credentialing products are obtained from publicly available sources
or are licensed, leased or purchased from the source of the data. Sources of
data for credentialing products include state medical boards, the Drug
Enforcement Agency, HCFA, the American Board of Medical Specialties, the
American Association of Medical Colleges and the National Association of Social
Workers. The data used in Medirisk's physician credentials recruiting products
are collected from publicly available sources and the AMA Physician MasterFile,
and are verified personal telephone interviews with each physician. Medirisk
employs professional interview personnel who contact physicians directly, gather
the required information, record the information in the automated database and
send a hard copy to each physician for verification. The Company believes that
the fact that each physician profiled in the Company's recruiting database has
personally verified the information and knows that he or she is tracked in the
database ensures the highest quality profile and offers a significant
competitive advantage over unverified databases. In addition, the Company is the
exclusive licensee of the AMA to share and enhance portions of the AMA's
Physician MasterFile. This relationship greatly enhances the quality and
availability of information about practicing physicians.
 
CUSTOMERS
 
     The unbiased nature of Medirisk's databases enables the Company to market
its products to a wide range of health care industry participants, including
managed care plans, indemnity insurers, integrated delivery systems, hospitals,
specialty health care providers, physician practice management companies,
physician practices, consulting firms and pharmaceutical firms. None of the
Company's customers, other than HEALTHSOUTH, Corporation accounted for a
material amount of the Company's revenues in 1997. During 1997, revenues from
HEALTHSOUTH represented approximately 16% of Medirisk's total revenues. Most of
Medirisk's major customers, which are defined as generating annualized revenue
of more than $5,000, license products in only one of the product areas offered
by the Company. Medirisk has approximately 1,000 major customers that in the
aggregate account for more than 90% of the Company's revenue.
 
PRODUCT DELIVERY
 
     The Company's products are delivered to customers on CD ROM, diskette,
magnetic tape, on-line access or hard copy depending upon customer preference.
Medirisk believes that there are readily available alternative sources of supply
for all of the media on which its products are delivered.
 
COMPETITION
 
     Medirisk faces intense competition in providing health care information
products and services. Competitors vary in size, scope and breadth of product
and service offerings. The Company competes with different competitors in each
of its target markets, and certain of such competitors have substantially
greater resources than those of the Company. In addition, several large
horizontally integrated information services companies, including Dow Jones, IMS
Healthcare, First Data Corporation, National Data Corporation, United Healthcare
and Thomson Publishing, have developed and are marketing information products
and services to the health care industry. The Company believes that it is likely
that one or more of such companies may become more direct competitors of the
Company either by acquiring existing competitors or by developing and marketing
their own products. Many of these larger companies are engaged in the processing
of health care claims and, thus, have access to substantial claims- and
cost-related data from which they could build competing databases or which they
could license to other competitors of the Company. The Company also competes
with the internal information resources and systems of certain of its
prospective and existing customers. The Company believes that the principal
competitive factors in its target markets include the breadth and quality of
database and applications offerings, access to proprietary data, the proprietary
nature of methodologies and technical resources, price and the effectiveness of
marketing and sales efforts.

EMPLOYEES
 
     On March 24, 1998, the Company had 209 full-time employees. Of these, 19
were corporate personnel, 34 were sales and marketing personnel and 156 were
involved in operations and product development. None of the Company's employees
is covered by a collective bargaining agreement. The Company considers relations
with its employees to be good.
 
ITEM 2.  PROPERTIES
 
     Medirisk's corporate headquarters occupy approximately 16,000 square feet
of an office building located in Atlanta, Georgia, under a lease expiring in
March 1999, with one optional five-year renewal term. Medirisk also leases
office space in Chicago, Illinois; St. Louis, Missouri; Rockville, Maryland; New
York, New York; and St. Paul, Minnesota. The Company believes that such offices
are adequate for the Company's current requirements.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     The Company is involved in various claims arising in the normal course of
business. In the opinion of management of the Company, although the outcomes of
these claims are uncertain, in the aggregate they are not likely to have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     No matter was submitted to a vote of the Company's security holders during
the quarter ended December 31, 1997.

dividends, if any, will be at the discretion of the Company's Board of
Directors. The Credit Agreement between the Company and NationsBank N.A.
contains restrictions on the payment of dividends. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
     The following discussion should be read in conjunction with the more
detailed information and consolidated financial statements and accompanying
notes, as well as the other financial information appearing elsewhere in this
Prospectus. Except for historical information, the following discussion contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results could differ materially from those discussed herein. Factors that
could cause or contribute to such differences include, but are not limited to,
those discussed in "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Forward Looking Statements."
 
OVERVIEW
 
     Medirisk is a provider of proprietary database products, decision-support
software and analytical services to the health care industry. The Company's
products and services enable its customers to make objective comparisons of the
financial costs and clinical outcomes of physician services to customer-specific
and industry benchmarks, assess patient satisfaction with specific managed care
plans, and access information concerning the background and credentials of
physicians. These capabilities assist health care industry participants in
measuring the performance of health care payors and providers.
 
     Applications of Medirisk's products include pricing managed care contracts,
evaluating physician fee schedules and utilization of physician services,
comparing provider outcomes and health plan performance, credentialing and
recruiting physicians, developing health care delivery networks, and marketing
health care services. The Company actively sells its products to over 1,000
major customers, including leading health plans, insurers, hospitals, large
multi-specialty physician groups, physician practice management companies,
employers, and pharmaceutical companies, as well as several hundred smaller
customers, including single-
 
                                       10
<PAGE>   12
 
specialty physician groups. Medirisk believes that it is the leading provider of
clinical and financial database products comprised of physician-oriented content
and managed care consumer satisfaction information in the United States.
 
ACQUISITIONS
 
     Following the completion of its initial public offering in January 1997,
Medirisk significantly expanded its operations by acquiring four companies. The
acquisition of businesses with complementary products and services has broadened
the Company's customer base, created additional cross-selling opportunities,
increased market share for existing products and resulted in new product
extensions and enhancements. The following summarizes these recent transactions.
 
     - In May 1997, Medirisk acquired substantially all of the assets of
       Staff-Link, Inc. ("Staff-Link") of St. Louis, Missouri, a provider of a
       physician database and related software utilities designed to assist
       health care organizations with their in-house recruiting efforts.
       Staff-Link's customer base increased the market share of the Company's
       physician credentials products.
 
     - In June 1997, Medirisk acquired CIVS, Inc. ("CIVS") of Rockville,
       Maryland, a leading national provider of physician credentialing services
       and information products to health care organizations. The acquisition of
       CIVS added new customers to the Company's physician credentials product
       line and broadened the range of products and outsourced services offered
       by the Company.
 
     - In August 1997, Medirisk acquired CareData Reports, Inc. ("CareData") of
       New York, New York, which creates reports analyzing consumer satisfaction
       with more than 150 aspects of managed health care plans and ranks
       specific health plans accordingly. CareData's products are used by
       managed care plans to assess their competitive position and quality of
       care, by employers to evaluate health plans and by pharmaceutical
       companies to target potential markets for their products.
 
     - In November 1997, Medirisk acquired Medsource, Inc. ("Medsource") of St.
       Paul, Minnesota, which licenses databases of physician information for
       use in recruiting physicians and developing health care networks. The
       acquisition strengthened the Company's physician credentials product line
       and extended the application of these products to the administrative and
       the marketing functions of health care organizations.
 
     In connection with the 1997 Acquisitions, the Company acquired intangible
assets which are being amortized over various useful lives. The amortization
periods are based on, among other things, the nature of the products and
markets, the competitive position of the acquired companies and the adaptability
to changing market conditions of the acquired companies. The Company recorded
amortization expense related to the 1997 Acquisitions of $300,000 for the year
ended December 31, 1997.
 
     Also in connection with these acquisitions, the Company recorded
non-recurring charges related to in-process research and development costs of
$3.1 million for CIVS, $975,000 for CareData and $300,000 for Medsource. The
amount of each of these non-recurring charges was equal to the estimated current
fair value, based on the adjusted cash flows (discounted by a risk-adjusted
weighted average cost of capital of 24% for CIVS and Care Data and 29% for
Medsource), of specifically identified technologies for which technological
feasibility had not yet been established pursuant to Statement of Financial
Accounting Standards No. 86, "Accounting for the Costs of Computer Software to
be Sold, Leased or Otherwise Marketed" and for which future alternative uses did
not exist. Similar charges could result in the future as a result of additional
acquisitions accounted for as purchases.
 
     The Company incurred approximately $200,000 of integration costs during
1997 for the 1997 acquisitions.
 
     As a result of the 1997 Acquisitions, the Company's historical financial
statements are not representative of financial results to be expected for future
periods. See Note 2 of Notes to Consolidated Financial Statements of the
Company.

SOURCES OF REVENUE
 
     The Company provides services and licenses its products primarily pursuant
to single- and multi-year contracts which provide for the payment of
nonrefundable annual fees, often in advance of use or shipment, or of quarterly
fees that are generally billed in advance of service delivery. The products are
segregated into three types: market performance, clinical performance and
physician credentials products. The market performance products provide
customers with information from the Company's market performance product
databases. Revenue on these sales is recognized upon the delivery of the data.
The Company also licenses the exclusive right to market the results of its
managed care consumer satisfaction surveys. Revenue from the licenses of
disease-specific customized surveys to the pharmaceutical industry is recognized
as the related costs of producing the survey are incurred, and revenue from
noncustomized data licensing is recognized upon delivery. The clinical
performance products revenues relate to the delivery of services and are
recognized over the contract terms as the services are provided. The physician
credentials products consist of (i) data and services provided to customers over
time, for which revenue is recognized ratably over the life of the contract, and
(ii) credentials reports that validate physicians' education, training and other
matters, for which revenue is recognized upon delivery of the completed reports.
Customer service revenues are recognized ratably over the service contract
period. All other revenue, including fees for training, consulting fees, and
other miscellaneous services, is recognized upon the performance of the
applicable services.
 
     The Company's revenue is composed of both recurring revenue from the
Company's current customer base as well as revenue from new customers. The
Company defines its recurring revenue percentage with respect to any particular
period as the quotient, expressed as a percentage, of (i) revenue recognized
during such period from a sale of a product to a customer who purchased a
similar product in the prior period divided by (ii) the Company's total revenue
in the prior period. In determining its recurring revenue percentage, the
Company includes in its revenue the revenue of entities acquired during the
period as if such acquisitions had occurred at the beginning of the prior
period. The Company does not include revenue in its recurring revenue percentage
to the extent that such revenue exceeds total revenue in the prior period. The
Company's recurring revenue percentage has been in excess of 70% for each of the
last four years.

</TABLE>
 
  YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
     Revenue.  Revenue in 1997 was $16.7 million, an increase of $7.8 million or
88% over 1996. The increase was primarily attributable to the acquisitions of
CIVS and CareData, effective in June 1997 and August 1997,
 
                                       12
<PAGE>   14
 
respectively. Revenue recognized by these acquired companies represented
approximately $4.3 million, or 55% of the total increase. The Company's revenue
without the impact of the revenue from the 1997 Acquisitions increased 45% for
1997 over 1996 as a result of a combination of factors, including the revenue of
a company acquired in March 1996 whose revenues were not included in the
Company's revenues for the entire year in 1996, increases in the volume of
products licensed and revenue attributable to an increase in the Company's sales
and marketing personnel. The volume increase was principally attributable to
licenses to new and existing customers for existing products and product
extensions.
 
     Salaries, wages and benefits.  Salaries, wages and benefits in 1997 were
$7.9 million, an increase of $1.8 million or 30% over 1996. This increase was
primarily the result of the acquisitions of CIVS and CareData and growth in the
revenues of the Company's other business units. Salaries, wages and benefits
decreased as a percentage of revenue during 1997 to 47% as compared to 68% for
the same period in 1996. This decrease resulted primarily from leveraging the
Company's existing administrative, sales and marketing personnel as revenue
increased through both acquisitions and internal growth.
 
     Other operating expenses.  Other operating expenses in 1997 were $4.4
million, an increase of $2.1 million or 89% over 1996, principally as a result
of the acquisitions of CIVS and CareData. Other operating expenses remained
generally consistent at 26% of revenue in 1997 and 1996.
 
     Depreciation and amortization.  Depreciation and amortization in 1997 was
$1.3 million, an increase of $517,000 or 66% over 1996. This increase resulted
primarily from the 1997 Acquisitions. As a percentage of revenue, depreciation
and amortization for 1997 and 1996 was 8% and 9%, respectively.
 
     Acquired in-process research and development costs and integration
costs.  In connection with the 1997 Acquisitions, the Company acquired the
ongoing research and development activities of each entity and incurred certain
integration expenses. At the effective date of each acquisition the Company
recorded non-recurring charges resulting from expensing acquired in-process
research and development costs. In 1997, the acquired in process research and
development costs and integration costs totaled $4.6 million, or 27% of revenue.
 
     Interest income (expense), net.  Net interest income in 1997 was $345,000,
an increase of $1.0 million over 1996. The increase was a result of the
extinguishment of debt with the proceeds of the Company's initial public
offering and the interest income earned on the net proceeds of that offering.
 
  YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     Revenue.  Revenue in 1996 was $8.9 million, an increase of $5.2 million or
144% over 1995. The increase was primarily attributable to the acquisitions of
Formations in Health Care, Inc. ("Formations") and PracticeMatch, Inc.
("PracticeMatch") effective in January and March 1996, respectively. Revenue
recognized by these acquired companies represented approximately $4.9 million,
or 93% of the total increase. The Company's revenue without the impact of the
revenue from the acquired companies increased 9% for 1996 over 1995 as a result
of a combination of factors, including increases in the volume of financial
products licensed and revenue attributable to an increase in the Company's sales
and marketing personnel. The volume increase was principally attributable to
licenses to new and existing customers as a result of product enhancements and
extensions.
 
     Salaries, wages and benefits.  Salaries, wages and benefits in 1996 were
$6.1 million, an increase of $3.5 million or 136% over 1995. This increase was
primarily the result of the acquisitions of Formations and PracticeMatch and, to
a lesser extent, growth in the Company's administrative, sales and marketing
infrastructure. Salaries, wages and benefits decreased as a percentage of
revenue in 1996 to 69% as compared to 71% in 1995. This decrease resulted
primarily from leveraging the Company's administrative, sales and marketing
personnel as revenue increased through both acquisitions and internal growth.
 
     Other operating expenses.  Other operating expenses in 1996 were $2.3
million, an increase of $1.4 or 142% over 1995, principally as a result of the
acquisition of Formations and PracticeMatch. Other operating expenses remained
constant at 26% of revenue in 1996 and in 1995.
 
                                       13
<PAGE>   15
 
     Depreciation and amortization.  Depreciation and amortization in 1996 was
$787,000, an increase of $593,000 or 307% over 1995. This increase resulted from
the acquisitions of Formations and PracticeMatch. As a percentage of revenue,
depreciation and amortization for 1996 and 1995 was 9% and 5%, respectively.
 
     Acquired in-process research and development costs.  In connection with the
acquisition of Formations and PracticeMatch, the Company acquired the ongoing
research and development activities of each entity. At the effective date of
each acquisition the Company recorded non-recurring charges resulting from
expensing acquired in-process research and development costs. These charges
totaled $6.2 million, or 69% of revenue, in 1996.
 
     Interest income (expense), net.  Net interest expense in 1996 was $703,000,
an increase of $638,000 or 975% over 1995. The increase was a result of interest
due on Senior Subordinated Notes issued during 1996 to finance the acquisition
of PracticeMatch as well as interest expense on the acquisition notes issued to
the sellers of PracticeMatch.

</TABLE>
 
     The Company's quarterly revenues and operating results have varied
significantly in the past. Quarterly results have fluctuated as a result of a
variety of factors including but not limited to the following: the Company's
sales cycle; staffing changes in the Company's sales and marketing organization;
changes in the Company's resources; demand for the Company's products; the
timing of significant new customer contracts; the non-renewal of significant
customer contracts; the timing of acquisitions; competitive conditions in the
industry; changes in customer budgets; and general economic factors.
Furthermore, the Company has experienced a seasonal pattern in its operating
results, with a greater proportion of the Company's revenue and operating
profitability occurring in the second half of the year. The Company attributes
this seasonality to a combination of factors including budgeting and other
factors affecting the health care industry generally, the compounding effect of
historical renewal schedules (which typically results in greater license
renewals in the third and fourth quarters) and internal staffing and growth
issues. The Company believes the licensing and subsequent renewal pattern of its
market performance products are more seasonal than its other products and
 
                                       14
<PAGE>   16
 
expects the addition of new products, including those from acquisitions, to
moderate, but not end, this seasonal effect.
 
     A significant portion of the Company's expenses are relatively fixed, and
the amount and timing of increases in such expenses are based in large part on
the Company's expectations concerning future revenue. If revenues are below
expectations in any given quarter, the adverse effect may be magnified by the
Company's inability to adjust spending quickly enough to compensate for the
revenue shortfall. Accordingly, even a small variation from expected revenue
could have a material adverse effect on the Company's results of operations for
a given quarter.
 
SOFTWARE CAPITALIZATION
 
     In addition to acquisitions, the Company seeks to expand its product
offerings through internal product development. Prior to 1996, the Company
expensed internal development costs due to the nominal costs incurred between
technological feasibility and product release. In 1997 the Company began
capitalizing internal product development costs which were incurred after
technological feasibility had been established and prior to general product
release. Capitalized software development costs net of accumulated amortization
totaled $1.0 million at December 31, 1997.
 
INCOME TAXES
 
     The Company recorded income tax expense of $707,000 during 1997 due to
limitations on the utilization of net operating loss carryforwards and the
nondeductability of certain acquired in-process research and development costs
to offset taxable income. At December 31, 1997, the Company had net operating
loss carryforwards of approximately $1.9 million for federal income tax
purposes. The net operating loss carryforwards expire beginning in 2006 through
2011. The total gross deferred tax asset was approximately $3.5 million as of
December 31, 1997 and has been reduced to zero by a valuation allowance and
offsetting deferred income tax liabilities of approximately $1.0 million.
 
     Deferred tax assets and liabilities are determined based on differences
between the financial reporting and the tax bases of assets and liabilities and
are measured using the enacted tax rates and laws that will be in effect when
the differences are expected to reverse. Applying the provisions of SFAS 109 to
the Company, particularly considering the Company's history of net losses, the
Company was unable to support a conclusion consistent with SFAS 109 that it is
more likely than not that it will generate future taxable income during the loss
carryforward periods; therefore, the Company has provided a full valuation
allowance against its net deferred tax assets. In determining that a valuation
allowance was required, management primarily considered such factors as the
Company's history of operating losses and expected near-term future losses and
earnings, the nature of the Company's deferred tax assets, the absence of
significant excess of appreciated asset value over the tax basis of the
Company's net assets, the absence of taxable income in prior carryback years and
the potential for deferred tax assets resulting from future business
acquisitions. Although management's operating plans assume taxable and operating
income in future periods, historical performance has produced an accumulated
deficit of $12.4 million at December 31, 1997. Consequently, the Company has
provided a full valuation allowance against its net deferred tax assets until
such time as the Company produces sufficient taxable and operating income to
support a lower valuation allowance.
 
     At December 31, 1997, the Company had net operating loss carryforwards of
approximately $1.9 million, which expire beginning in 2006 through 2011. Under
Internal Revenue Code Section 382, the Company's use of net operating loss
carryforwards is limited to approximately $1.1 million per year as a result of
the Company's initial public offering completed in January 1997 (see Note 8(h)
of Notes to Consolidated Financial Statements). Approximately $1.0 million of
the net operating loss at December 31, 1997 relates to loss carryforwards
acquired in connection with the 1997 Acquisitions. Accordingly, such losses are
limited to income generated by the acquired entity as well as substantial annual
limitations.

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company completed its initial public offering of Common Stock in
January 1997 and received approximately $22.6 million in net proceeds.
Approximately $9.1 million of these net proceeds were used to repay a senior
subordinated note and certain notes issued in connection with the Company's
acquisition of PracticeMatch, to pay accrued dividends on the Company's Series A
and Series B Convertible Preferred Stock and to repay a bridge loan provided by
NationsBank. In 1997, the Company used $11.4 million of the remaining net
proceeds of its initial public offering for working capital and general
corporate purposes, including the funding of the 1997 Acquisitions and
development of new products.
 
     In March 1997, NationsBank and the Company entered into a Credit Agreement
under which a $10.0 million revolving credit facility (the "NationsBank
Revolver") is available to the Company. The NationsBank Revolver is secured by
substantially all of the Company's assets. Under the terms of the NationsBank
Revolver the Company may, subject to customary terms, conditions and covenants,
borrow up to $10.0 million to fund working capital needs, new product
development and acquisitions. The Credit Agreement for the NationsBank Revolver
provides for interest at varying rates based on LIBOR and NationsBank's prime
rate and will mature on March 28, 1999. Under the terms of the NationsBank
Revolver, the Company is subject to various restrictive covenants regarding,
among other things, payment of any dividends, capital expenditures limitations,
incurrence of indebtedness from others in excess of certain amounts, and
consummation of certain mergers and acquisitions without the consent of
NationsBank. Financial covenants include, but are not limited to, maintaining
debt to capitalization ratios, minimum net worth ratios, debt service coverage
ratios and cash flow leverage ratios. No amounts were outstanding under the
Credit Agreement during 1997.
 
     The Company currently has no specific plans with respect to the use of the
remaining $2.1 million of the net proceeds of its initial public offering or the
NationsBank Revolver, and the Company's cash flow from operations has generally
been sufficient to fund the liquidity needs of the Company other than
acquisitions and new product development. The Company anticipates that
borrowings under the NationsBank Revolver and the remaining net proceeds of the
initial public offering will be used principally for working capital and general
corporate purposes, for potential acquisitions of complementary businesses or
products in the health care information industry and for the development of
additional products. Pending the application of the remaining net proceeds of
its initial public offering, the Company has invested such proceeds in
short-term, interest-bearing, investment-grade securities.
 
     In January 1996, the Company and HealthPlan Services Corporation ("HPSC")
entered into a Securities Purchase Agreement, under which HPSC purchased 280,623
shares of Series B Convertible Preferred Stock for $2.0 million and agreed to
purchase up to $10.0 million in original principal amount of Senior Subordinated
Notes. In connection with the issuance of the Senior Subordinated Notes, the
Company agreed to issue warrants to purchase up to 432,101 shares of Common
Stock for $0.015 per share. In March 1996, the Company issued $6.9 million in
original principal amount of the Senior Subordinated Notes to HPSC and warrants
to purchase 298,150 shares of Common Stock. (In February 1998, these warrants
were exercised.) The Company used $1.5 million of the proceeds from the sale of
Series B Convertible Preferred Stock to complete the acquisition of Formations.
Medirisk used approximately $5.4 million of the proceeds from the issuance of
the Senior Subordinated Notes to complete the acquisition of PracticeMatch. In
addition, in connection with the PracticeMatch acquisition, the Company issued
acquisition notes to the sellers in an aggregate principal amount of $1.1
million. The HPSC Senior Subordinated Notes, a NationsBank bridge loan and the
acquisition notes were repaid in full upon the completion of the Company's
initial public offering in January 1997. Upon such repayment HPSC's obligation
to purchase additional Senior Subordinated Notes terminated.
 
     The Company had working capital of $4.2 million as of December 31, 1997 as
compared to a working capital deficit of $2.5 million as of December 31, 1996.
This increase is primarily due to the receipt of the net proceeds of the
Company's initial public offering.
 
     Net cash used by operating activities totaled $697,000 for the year ended
December 31, 1997, as compared $762,000 for the prior year. The decrease in cash
used of $65,000 was primarily the result of the timing of customer payments.
                                       16
<PAGE>   18
 
     Net cash used in investing activities was approximately $9.3 million for
the year ended December 31, 1997, as compared to $7.3 million for the prior
year. In 1996, $7.0 million was used to fund the acquisitions of Formations and
PracticeMatch, while, in 1997, $7.4 million was used to fund the 1997
Acquisitions. The remaining $1.9 million of net cash used in investing
activities in the year ended December 31, 1997 was used to fund fixed asset
purchases and software development.
 
     Net cash provided by financing activities was $13.1 million for the year
ended December 31, 1997, as compared to $8.2 million for the same period in the
prior year. As previously discussed, in 1997 the Company retained $13.5 million
of the net proceeds from its initial public offering, and the cash provided in
1996 resulted from the net proceeds under the HPSC Securities Purchase
Agreement.
 
     The Company believes that the remaining proceeds of its initial public
offering, borrowings under the NationsBank Revolver and cash generated from
operations will be sufficient to meet the capital expenditure and working
capital needs for the Company's operations for the near term. The Company's
future liquidity and cash requirements will depend on a wide range of factors,
including costs associated with development of new products, enhancements of
existing products and acquisitions. Although the Company has no present
commitments or agreements regarding acquisitions, the Company's strategy is to
acquire additional complementary products and businesses. If the remaining
proceeds of the initial public offering, borrowings under the NationsBank
Revolver and cash flow from operations are not sufficient to fund such
acquisitions, the Company will be required to seek additional financing, and
there can be no assurance that such financing will be available in amounts and
on terms acceptable to the Company.
 
RECENT ACCOUNTING PRONOUNCEMENT
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income ("SFAS No. 130"). SFAS No. 130 requires companies to display, with the
same prominence as other financial statements, the components of comprehensive
income. SFAS No. 130 requires that an enterprise classify items of other
comprehensive income by their nature in a financial statement and display the
accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. SFAS No. 130 is effective for fiscal years beginning after

provided for comparative purposes is required. The Company's financial
statements will include the disclosure of comprehensive income in accordance

     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, Disclosures about Segments of an Enterprise and Related Information
("SFAS No. 131"). SFAS No. 131 requires that an enterprise disclose certain
information about operating segments. SFAS No. 131 is effective for financial

evaluate the need for such disclosures at that time.
 
     In October 1997, the Accounting Standards Executive Committee issued
Statement of Position 97-2, Software Revenue Recognition ("SOP 97-2"). SOP 97-2
is effective for financial statements for fiscal years beginning after December
15, 1997. The Company does not expect that adoption of SOP 97-2 will
significantly affect its results of operations.
 
YEAR 2000 COMPLIANCE
 
     The Company is addressing the Year 2000 compliance issues on the software
that it licenses and uses in its products and on the software that it uses
internally. Based on its current analysis, the Company believes that Year 2000
compliance will not have a material effect on its business, operations or
financial condition, as remediation costs either have been incurred or the costs
estimated to be incurred are not material.

EFFECTS OF INFLATION
 
     Management does not believe that inflation has had a material impact on
results of operations for the periods presented. Substantial increases in costs,
particularly the cost of labor for product development, marketing and sales,
could have an adverse impact on the Company's business, operating results and
financial condition.

adopted and the stockholders of the Company approved the Medirisk, Inc. 1996
Stock Incentive Plan (the "1996 Incentive Plan"). Pursuant to the 1996 Incentive
Plan, awards are permitted to be granted in the form of non-qualified stock
options, incentive stock options, stock appreciation rights and shares of
restricted stock. In addition, the 1996 Incentive Plan provides for several
types of equity-based incentive compensation awards, namely performance units,
performance shares, phantom stock, unrestricted bonus stock and dividend
equivalent rights.
 
     The 1996 Incentive Plan is administered by the Compensation Committee of
the Board of Directors. The Compensation Committee determines the persons to
whom, and the times at which, awards will be granted, the type of awards to be
granted and all other related terms and conditions of the awards, subject to
certain limitations set forth in the 1996 Incentive Plan. All officers and key
employees of the Company and its affiliates are eligible to participate in the
Incentive Plan.
 
     A total of 580,645 shares of Common Stock are reserved for issuance
pursuant to the 1996 Incentive Plan. In the event of a Change in Control of the
Company (as defined in the 1996 Incentive Plan), stock incentives will become
fully vested without regard to the exercisability of the award or any other
conditions or restrictions. In connection with the Company's initial public
offering, the Company caused all then-existing outstanding options (which had
not been issued under any plan) to be surrendered in exchange for options with
identical terms issued under the 1996 Incentive Plan. As of March 24, 1997,
there were options for 523,023 shares of Common Stock outstanding under the 1996
Incentive Plan, and 36,080 shares of Common Stock are reserved for future
issuance under the 1996 Incentive Plan.
 
     Medirisk, Inc. 1998 Qualified Employee Stock Purchase Plan.  The Company's
Board of Directors has adopted, subject to stockholder approval at the Annual
Meeting of Stockholders to be held in May 1998, the Medirisk, Inc. 1998
Qualified Employee Stock Purchase Plan (the "ESPP"). If approved by the
stockholders at the Company's Annual Meeting of Stockholders to be held in May
1998, the ESPP will be effective as of its adoption by the stockholders, and
payroll deductions under the ESPP will begin on July 1, 1998. The purpose of the
ESPP is to encourage employees of the Company and any participating subsidiaries
to acquire a proprietary interest, or to increase their existing proprietary
interest, in the Company. The ESPP will be administered by the Compensation
Committee.
 
     The total number of shares of Common Stock for which options may be granted
under the ESPP is 200,000 shares, subject to adjustment in accordance with the
ESPP. The ESPP permits participating employees to purchase shares of Common
Stock through payroll deduction for the lesser of (i) 85% of the fair market
value of the Common Stock on the first business day of an applicable purchase
period, or (ii) 85% of
 
                                       23
<PAGE>   25
 
the fair market value of the Common Stock on the last business day of the
purchase period. Applicable purchase periods are the calendar quarters of each
fiscal year of the Company.
 
     Each employee of the Company and each employee of any designated subsidiary
corporation of the Company that has adopted the ESPP for the benefit of its
employees (the Company and each such other corporation being referred to herein
as a "Participating Company") is eligible to participate in the ESPP, provided
such employee: (i) is regularly scheduled to work at least 20 hours each week
and at least five months in the calendar year, and (ii) immediately after the
grant of an option to him under the ESPP would own less than five percent of the
total combined voting power or value of all classes of stock of the Company or
any of its subsidiaries. As of March 24, 1998, there were approximately 200
employees eligible to participate in the ESPP, but no shares or options had been
issued under the ESPP.
 
     Medirisk Non-Management Directors' Stock Option Plan.  The Medirisk, Inc.
Non-Management Directors' Stock Option Plan provides for the issuance of
non-qualified stock options to directors of the Company who are not employed by
or otherwise affiliated with the Company. A total of 100,000 shares of Common
Stock are reserved for issuance pursuant to the Directors' Plan. The effective
date of the Directors' Plan was January 28, 1997, the effective date of the
Company's initial public offering. As of March 24, 1997, there were options for
75,000 shares of Common Stock outstanding under the Incentive Plan.
 
     Medirisk, Inc. 1998 Long-Term Incentive Plan.  The Board of Directors of
the Company has adopted, subject to stockholder approval at the Company's Annual
Meeting of Stockholders to be held in May, 1998, the Medirisk, Inc. 1998
Long-Term Incentive Plan (the "Long-Term Incentive Plan"). If approved by the
stockholders at the Annual Meeting, the Long-Term Incentive Plan will be
effective as of its adoption by the stockholders, and awards may be made at any
time following such approval, although it is the Company's intention to grant
awards with respect to shares remaining available under the 1996 Incentive Plan
before granting awards under the Long-Term Incentive Plan. Pursuant to the
Long-Term Incentive Plan, awards are permitted to be granted in the form of
non-qualified stock options, incentive stock options, stock appreciation rights
and shares of restricted stock. In addition, the Long-Term Incentive Plan
provides for several types of equity-based incentive compensation awards, namely
performance units, performance shares, phantom stock, unrestricted bonus stock
and dividend equivalent rights.
 
     The Long-Term Incentive Plan will be administered by the Compensation
Committee of the Board of Directors. The Compensation Committee determines the
persons to whom, and the times at which, awards will be granted, the type of
awards to be granted and all other related terms and conditions of the awards,
subject to certain limitations set forth in the Long-Term Incentive Plan. All
directors, officers and key employees of the Company and its affiliates are
eligible to participate in the Long-Term Incentive Plan.
 
     A total of 500,000 shares of Common Stock will be reserved for issuance
pursuant to the Long-Term Incentive Plan. In the event of a Change in Control of
the Company (as defined in the Long-Term Incentive Plan), stock incentives will
become fully vested without regard to the exercisability of the award or any
other conditions or restrictions. As of March 24, 1997, there were no options or
other awards outstanding under the Long-Term Incentive Plan.

<PAGE>   26

shares on May 31, 1998. These subsequent options will have an exercise price
equal to the fair market value of the Common Stock on May 31, 1998. All of the

of grant or immediately upon the sale or other change of control involving the
Company. Mr. Kaiser's agreement contains a nondisclosure covenant, as well as
covenants not to divert business or employees from the Company for one year
following termination. In the event Mr. Kaiser terminates his employment for
good reason, as defined in the agreement (which includes a voluntary termination
by Mr. Kaiser one year after a change of control involving the Company), or if

agreement, Mr. Kaiser shall be entitled to continue to receive his base salary
and all benefits until the later of May 31, 1999, or one year from the date of
termination.

1997, is also an Executive Vice President and Chief Financial Officer of Sykes
HealthPlan Services, Inc., a joint venture between Health Plan Services

issued to HPSC 280,623 shares of Series B Convertible Preferred Stock for $2.0
million and Senior Subordinated Notes in an original principal amount equal to

In connection with the Company's initial public offering, during 1997 the
Company paid $6.9 million to HPSC in repayment of the HPSC Senior Subordinated
Notes, and the Series B Convertible Preferred Stock was automatically converted
into 182,292 shares of Common Stock.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
  Medirisk, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Medirisk,
Inc. and subsidiaries as of December 31, 1997 and 1996, and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for each of the years in the three-year period ended December 31, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Medirisk,
Inc. and subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1997, in conformity with generally accepted accounting
principles.

satisfaction with specific managed care plans, and obtain information concerning
the background and credentials of physicians. These capabilities assist health
care industry participants in measuring the performance of health care payors
and providers.
 
     Applications of Medirisk's products include pricing managed care contracts,
evaluating physician fee schedules and utilization of physician services,
comparing provider outcomes and health plan performance, credentialing and
recruiting physicians, developing health care delivery networks, and marketing
health care services. The Company actively sells its products to leading health
plans, insurers, hospitals, large multi-specialty physician groups, physician
practice management companies, employers, and pharmaceutical companies, as well
as smaller customers, including single-specialty physician groups.
 
  (b) Basis of Financial Statement Presentation
 
     The consolidated financial statements have been prepared in conformity with
generally accepted accounting principles. In preparing the consolidated
financial statements, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities as of the date of the
balance sheet, income and expenses for the period, and disclosure of contingent
assets and liabilities. Actual results could differ from those estimates.
 
     The consolidated financial statements include the accounts of Medirisk,
Inc. and its subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation.
 
  (c) Cash Equivalents
 
     Cash equivalents at December 31, 1997 and 1996 included amounts of
$2,106,963 and $145,897, respectively, invested in money market accounts with a
major brokerage firm. For purposes of the statement of cash flows, the Company
considers all highly liquid debt instruments with original maturities of three
months or less to be cash equivalents.
 
  (d) Revenue Recognition
 
     The Company provides services and licenses its products primarily pursuant
to single- and multi-year contracts which provide for the payment of
nonrefundable annual fees, often in advance of use or shipment, or of quarterly
fees generally billed in advance of service delivery. The products are
segregated into three types: market performance, clinical performance, and
physician credentials products. The market performance products provide
customers with information from the Company's market performance product
databases. Revenue on these sales is recognized upon the delivery of the data.
The Company also licenses the exclusive rights to market the results of its
managed care consumer satisfaction surveys. Revenue from the licenses of
disease-specific customized surveys to the pharmaceutical industry is recognized
as the related costs of producing the survey are incurred, and revenues from
noncustomized data licensing is recognized upon delivery. The clinical
performance products revenues relate to the delivery of services and are
recognized over the contract terms as the services are provided. The physician
credentials products consist of (i) data and services provided to customers over
time, for which revenue is recognized ratably over the life of the contract, and
(ii) credentials reports that validate physicians' education, training, and
other matters, for which revenue is recognized upon delivery of the completed
reports. Customer service revenues are recognized ratably over
 
                                       37
<PAGE>   39
 
the service contract period. All other revenue, including fees for training,
consulting fees, and other miscellaneous services, is recognized upon the
performance of the applicable services.
 
  (e) Deferred Revenue
 
     Deferred revenue represents accounts receivable and payments to the Company
by customers in advance of revenue recognition.
 
  (f) Accounts Receivable
 
     The Company enters into multi-year, non-cancelable subscription contracts,
for which the associated receivables are recorded as accounts receivable and
deferred revenue when they become due. The contract balances are due at the
beginning of their respective annual anniversary dates.
 
  (g) Property and Equipment
 
     Property and equipment are stated at cost, less accumulated depreciation
and amortization. Depreciation is provided on the straight-line method over the
estimated useful lives of the assets ranging from three to seven years.
Amortization of assets acquired under capital lease arrangements not
transferring ownership or without a bargain purchase option is recorded using
the straight-line method over the estimated useful lives of the assets or the
lease term, whichever is shorter.
 
  (h) Excess of Cost Over Net Assets of Businesses Acquired
 
     The excess of cost over net assets of businesses acquired (goodwill) is
being amortized using the straightline method over a period of 15 years. The
amortization period is based on, among other things, the nature of the products
and markets, the competitive position of the acquired companies, and the
adaptability to changing market conditions of the acquired companies. At each
balance sheet date, the Company assesses the recoverability of this intangible
asset by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash flows
of the acquired operation. The amount of goodwill impairment, if any, is
measured based on projected discounted future operating cash flows using a
discount rate equal to the rate of return that would be required by the Company
for a similar investment with like risks.
 
  (i) Other Intangible Assets
 
     Other intangible assets are comprised mainly of acquired products and
acquired customer contracts. The costs of acquired products and acquired
customer contracts from business acquisitions are derived using a fair value
method of allocation. Other intangible assets are being amortized using the
straight-line method over five years. The Company makes an ongoing assessment of
the recoverability of its intangible assets by comparing the amount capitalized
for each asset to the estimated net realizable value ("NRV") of the asset. If
the NRV is less than the amount capitalized, a write-down to NRV is recorded.
 
  (j) Research and Development Costs and Software Development Costs
 
     Research and development costs are expensed as incurred. Amounts expensed
for research and development for the years ended December 31, 1997, 1996, and
1995, were $2,149,155, $951,645, and $221,943, respectively.
 
     The Company capitalizes software development costs by project, commencing
when technological feasibility for the respective product is established and
concluding when the product is ready for general release to customers. The
Company makes an ongoing assessment of the recoverability of its capitalized
software projects by comparing the amount capitalized for each product to the
estimated NRV of the product. If the NRV is less than the amount capitalized, a
write-down to NRV is recorded. The Company capitalized computer software
development costs of $983,937 and $120,969 for the years ended December 31, 1997
and 1996, respectively. Capitalized computer software development costs are
being amortized using the straight-
 
                                       38
<PAGE>   40
 
line method over an estimated useful life of five years. Amortization expense
was $76,597 and $19,911 for the years ended December 31, 1997 and 1996,
respectively.
 
  (k) Stock Option Plans
 
     Prior to January 1, 1996, the Company accounted for its stock option plans
in accordance with the provisions of Accounting Principles Board ("APB") Opinion
No. 25, Accounting for Stock Issued to Employees, and related interpretations.
As such, compensation expense to be recognized over the related vesting period
would generally be determined on the date of grant only if the current market
price of the underlying stock exceeded the exercise price. On January 1, 1996,
the Company adopted Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation ("SFAS 123"), which permits entities to
recognize as expense over the vesting period the fair value of all stock-based
awards on the date of grant. Alternatively, SFAS 123 also allows entities to
continue to apply the provisions of APB Opinion No. 25 and provide pro forma net
income (loss) and pro forma income (loss) per share disclosures for employee
stock option grants made in 1995 and future years as if the fair-value-based
method defined in SFAS 123 had been applied. The Company has elected to continue
to apply the provisions of APB Opinion No. 25. The pro forma effects of SFAS 123
for 1997 and 1996 are presented in footnote 8(c). The effects of SFAS 123 for
1995 are not material to the Company's consolidated financial statements and,
therefore, the pro forma and other disclosure requirements have not been
presented.
 
  (l) Net Loss Per Share of Common Stock
 
     On December 31, 1997, the Company adopted Statement of Financial Accounting
Standards No. 128, Earnings Per Share ("SFAS 128"), which prescribes the
calculation methodology and financial reporting requirements for basic and
diluted earnings per share. Basic earnings (loss) per common share available to
common shareholders is based on the weighted-average number of common shares
outstanding. Diluted earnings (loss) per common share available to common
shareholders is based on the weighted-average number of common shares
outstanding and dilutive potential common shares, such as dilutive stock
options.
 
     Retroactive restatement has been made to share and per share amounts for
the reverse stock split (see note 8(g)) and conversion of all of the Company's
Series A convertible preferred stock and Series B convertible preferred stock
into common stock which occurred upon consummation of the Company's initial
public offering in January 1997 (see note 8(h)). Weighted average number of
shares of common stock outstanding through December 31, 1996 has been calculated
pursuant to Securities and Exchange Commission Staff Accounting Bulletin No. 98
("SAB 98") whereby common stock, options, warrants, or other potentially
dilutive instruments that are issued for nominal consideration ("nominal
issuances") during the periods covered by statements of operations included in
the Registration Statement for an initial public offering are reflected in
earnings per share calculations in a manner similar to a stock split or stock
dividend for which retroactive restatement is required. The Company had nominal
issuances in the periods covered by its Registration Statement for its initial
public offering. The computation of diluted net loss per share of common stock
was antidilutive in each of the periods presented; therefore, the amounts
reported for basic and diluted net loss per share are the same.
 
     All prior period net loss per share data presented in these consolidated
financial statements have been restated to conform to the provisions of SFAS 128
and SAB 98.
 
  (m) Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
of
 
     The Company adopted the provisions of SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of, on
January 1, 1996. This statement requires that long-lived assets be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment to be recognized is measured by
the
 
                                       39
<PAGE>   41
 
amount by which the carrying amount of the assets exceed the fair value of the
assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell.
 
  (n) Income Taxes
 
     Deferred income tax assets and liabilities are recognized for the future
tax consequences attributable to differences between financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss carryforwards. Deferred income tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred income tax assets and liabilities
of a change in tax rates is recognized in income in the period that includes the
enactment date.

     Based on the borrowing rates currently available to the Company for debt
with similar terms and average maturities, the fair value of long-term debt
approximates its carrying value.
 
     On March 28, 1997, the Company entered into a two-year $10,000,000 line of
credit agreement (the "Credit Agreement") with a commercial bank. Borrowings
under the Credit Agreement accrue interest at either prime or LIBOR plus 1.65%
to 2.25%, depending on interest rate elections made by the Company and certain
financial ratio positions as defined in the Credit Agreement. Interest on
borrowings is payable monthly and principal is due at expiration of the Credit
Agreement, March 28, 1999. Borrowings under the Credit Agreement are subject to
certain customary financial covenants and dividend restrictions and are secured
by substantially all of the Company's assets. There were no borrowings under the
Credit Agreement during 1997.
 
(5) HEALTHPLAN SERVICES SECURITIES PURCHASE AGREEMENT (SEE NOTE 8(H))
 
     On January 8, 1996, for the purpose of financing the Company's ongoing
acquisition program and working capital needs, the Company and HealthPlan
Services Corporation ("HPSC"), entered into a Securities Purchase Agreement (the
"Agreement"). Under the Agreement, HPSC purchased 280,623 shares of the
Company's Series B convertible preferred stock for $2,000,000 (see note 8) and
agreed to purchase up to $10,000,000 in original principal amount of senior
subordinated notes. In addition, HPSC would be issued warrants to purchase up to
432,101 shares of the Company's common stock for $0.015 per share, based upon
the amount of senior subordinated debt purchased. HPSC's obligation to purchase
senior subordinated notes under the Agreement terminated upon the earliest to
occur of (i) an initial public offering of the Company; (ii) a change of control
of the Company; (iii) an event of default; (iv) January 8, 1999; or (v) the
death or termination of employment of the Company's Chairman and Chief Executive
Officer.

<PAGE>   45
 
     On March 13, 1996, the Company sold a $6,900,000 senior subordinated note
to HPSC. The note bore interest at 10% payable quarterly and was due upon the
earliest to occur of (i) an initial public offering by the Company; (ii) a
change of control of the Company; or (iii) at maturity on January 8, 2003.
Warrants to purchase 298,150 shares of the Company's common stock were issued to
HPSC in connection with issuance of this note. The proceeds received were
allocated to the notes and the warrants based on their relative fair values
resulting in a discount of $573,111 on the note, which was being amortized over
the life of the note.
 
     On January 31, 1997, the Company consummated an initial public offering
(see note 8(h)). As a result, the Agreement was terminated and the $6,900,000
note payable to HPSC was repaid. The Company recorded a charge of $806,146 for
early extinguishment of debt relating to the unamortized note discount and
related deferred financing costs.

respectively.
 
  (b) Employment Agreement
 
     The Company has entered into an Employment Agreement (the "Employment
Agreement") with the Company's Chairman and Chief Executive Officer (the "CEO").
The Employment Agreement provides for a base salary subject to annual increases
at the discretion of the compensation committee, annual performance bonuses
based upon attaining certain goals established by the compensation committee,
minimum annual stock option grants, and certain severance benefits in the event
of termination. The Employment Agreement expires on May 31, 1999 and is
automatically renewable for one-year terms thereafter, subject to termination by
the Company or the CEO upon 60 days' notice.
 
  (c) Employee Benefit Plan
 
     The Company maintains a 401(k) plan (the "Plan") for the benefit of all
eligible employees. The Plan provides for employer matching contributions at the
discretion of the Company's management. The Company has not paid or accrued an
amount for matching contributions since the inception of the Plan.
 
(7) INCOME TAXES
 
     Income tax expense for the year ended December 31, 1997 was $707,000. All
of the $707,000 is current; $640,000 is federal and $67,000 is state tax
expense.

</TABLE>
 
     The net change in the valuation allowance for the years ended December 31,
1997 and 1996 was a (decrease) increase of $(568,217) and $2,774,215,
respectively. Deferred income tax assets and liabilities are initially
recognized for differences between the financial statement carrying amount and
the tax bases of assets and liabilities which will result in future deductible
or taxable amounts and operating loss and tax credit carryforwards. A valuation
allowance is then established to reduce the deferred income tax asset to the
level at which it is "more likely than not" that the tax benefits will be
realized. Realization of tax benefits of deductible temporary differences and
operating loss or credit carryforwards depends on having sufficient taxable
income of an appropriate character within the carryback and carryforward
periods. Sources of taxable income that may allow for the realization of tax
benefits include: (1) taxable income in the current year or prior years that is
available through carryback; (2) future taxable income that will result from the
reversal of existing taxable temporary differences; and (3) taxable income
generated by future operations.
 
     The valuation allowance at December 31, 1997 includes approximately $1.0
million that will reduce goodwill if and when the tax benefits from an acquired
net operating loss are subsequently recognized.
 
     At December 31, 1997, the Company had net operating loss carryforwards of
approximately $1.9 million, which expire beginning in 2006 through 2011. Under
Internal Revenue Code Section 382, the Company's use
 
                                       45
<PAGE>   47
 
of net operating loss carryforwards is limited to approximately $1,100,000 per
year as a result of the Company's initial public offering completed in January
1997 (see note 8(h)). Approximately $1.0 million of the net operating loss at
December 31, 1997 relates to loss carryforwards acquired in connection with the
1997 Acquisitions. Accordingly, such losses are limited to income generated by
the acquired entity as well as substantial annual limitations.
 
(8) STOCKHOLDERS' EQUITY (DEFICIT)
 
  (a) Articles of Incorporation
 
     On January 8, 1996, the Company's articles of incorporation were amended to
increase the number of authorized shares of common stock from 5,000,000 shares
to 20,000,000 shares and to establish 400,000 authorized shares of Series B
convertible preferred stock. On that same date, the Company's articles of
incorporation were amended to remove the redeemable feature from the Company's
Series A convertible preferred stock.
 
     In September 1996, the Company was reincorporated in Delaware, and in
connection with such reincorporation, the Company's treasury stock was canceled
and an additional 1,000,000 shares of preferred stock were authorized. In
addition, the Company's articles of incorporation were amended such that the
Company's Series A and Series B convertible preferred stock would be canceled
and no longer authorized upon completion of an initial public offering (see note
8(h)).
 
  (b) Series A and Series B Convertible Preferred Stock (see note 8(h))
 
     Until January 1996, the Series A convertible preferred stock (Series A
"CPS") carried a mandatory redemption feature pursuant to a Stockholders'
Agreement which required the Company to redeem all outstanding shares of Series
A CPS on the seventh anniversary of the original issue date (April 5, 1998) at a
price equivalent to the liquidation price of $1.95. In January 1996, the
redemption feature was eliminated and the balance related to this security was
reclassified to stockholders' equity.
 
     The holders of the Company's Series A CPS were entitled to dividends on a
cumulative basis at 8% which began on April 5, 1994. The holders of the
Company's Series B convertible preferred stock (Series B "CPS") were entitled to
dividends on a cumulative basis at 8% beginning on January 8, 1997. The Series A
CPS and Series B CPS were convertible at the option of the holder at any time
into common stock at a ratio of 0.6496 share for one share, subject to
adjustment in certain circumstances, and the holders of the Series A CPS and
Series B CPS carried voting power equivalent to the number of common shares into
which their preferred shares could be converted. Furthermore, the Company was
restricted from paying dividends on the Company's common stock until all unpaid
dividends on the Series A CPS and Series B CPS were paid. In no event could the
Series A CPS and Series B CPS dividends be paid until payment in full of the
senior subordinated note payable. These dividends payable were classified as
noncurrent at December 31, 1996 (see note 8(h)).
 
     In the event of liquidation, holders of the Series A CPS and Series B CPS
were entitled to the sum of (a) $1.95 per preferred share for Series A CPS and
$7.13 per preferred share for Series B CPS, (b) all accrued and unpaid
dividends, and (c) the portion of the fair market value of the assets and
liabilities of the Company attributable to the Series A CPS and Series B CPS
holders determined by the number of common shares that would be held by the
Series A CPS and Series B CPS holders upon conversion to common stock.
Additionally, the Series A CPS and Series B CPS would automatically convert upon
the occurrence of certain future events such as an initial public offering, as
defined, and the Company was required to obtain prior approval of the holders of
the Series A CPS and Series B CPS to effect certain transactions. The holders of
the Series A CPS and Series B CPS also carried certain other rights and
privileges, as further defined in the agreements.
 
     During 1994 notes payable of $300,000 and accrued interest of $18,000 were
converted into 318,000 shares of the Company's Series A CPS at a conversion
price of $1.00 per share. Until January 1996, the discount of $302,100 resulting
from the 1994 conversion, and the discount associated with the original issuance
 
                                       46
<PAGE>   48
 
of the Series A CPS of $96,450, representing the difference between the recorded
value of the Series A CPS and the redemption value, were being accreted using
the straight-line method from issuance date through April 5, 1998, the first
date that the holders could have required redemption.
 
     As a result of the Company's initial public offering in January 1997, the
Series A CPS and Series B CPS were converted into 1,021,809 shares of common
stock of the Company.
 
  (c) Stock Options
 
     The Company periodically grants stock options to encourage stock ownership
by, and retain the services of, certain key employees. Options granted are
determined at the discretion of the Board of Directors. All options granted are
earned over a five-year vesting period at 20% per year, and expire at the
earlier of three months after termination of employment or ten years from date
of grant.
 
     In October 1996, the Board of Directors of the Company adopted the
Medirisk, Inc. 1996 Stock Incentive Plan (the "Incentive Plan") and the
Medirisk, Inc. Non-Management Directors' Stock Option Plan (the "Directors'
Plan"). A total of 580,645 shares of common stock have been reserved for
issuance under the Incentive Plan and 100,000 shares of common stock have been
reserved for issuance under the Directors' Plan.
 
     The Company has elected to follow APB Opinion No. 25 and related
interpretations in accounting for its stock options. Under APB Opinion No. 25,
because the exercise price of the Company's employee stock options equals the
market price of the underlying stock on the date of grant, no compensation
expense is recognized. However, SFAS 123 requires presentation of pro forma net
earnings (loss) and pro forma earnings (loss) per share as if the Company had
accounted for its employee stock options granted subsequent to December 31, 1994
under the fair value method of that statement. The pro forma effect for 1995 is
not material. For purposes of pro forma disclosure, the estimated fair value of
the options is amortized to expense over the vesting period. Under the fair
value method, the Company's net loss and loss per share would have been
increased as follows:

     Because SFAS 123 is applicable only to options granted subsequent to
December 31, 1994, and the options generally have a five-year vesting period,
the pro forma effect will not be fully reflected until 1999.
 
     The per share weighted-average fair values of stock options granted during
1997 and 1996 were $7.02 and $0.25, respectively, on the date of grant using the
Black-Scholes option-pricing model with the following assumptions:

  (d) Stockholders' Agreement (see note 8(h))
 
     The Company is party to a Stockholders' Agreement (the "Stockholders'
Agreement") among all preferred and common stockholders of the Company which
includes restrictions and requirements, certain of which are disclosed below.
The Stockholders' Agreement establishes the composition of the Company's Board
of Directors and provides for restrictions on the transfer of the Company's
shares. Additionally, the Stockholders' Agreement provided for a one-time
dividend to Series A CPS holders equivalent to 4% of the original purchase price
of the Series A CPS. The dividend was cumulative and accrued from April 5, 1993
to April 5, 1994. In no event could the Series A CPS onetime dividend be paid
until payment in full of the senior subordinated note payable. This dividend
payable was classified as noncurrent at December 31, 1996.
 
     The Company was required to reserve at all times common shares sufficient
to satisfy the exercise of all outstanding stock options and warrants, and to
satisfy the conversion of all Series A CPS and Series B CPS.
 
     As a result of the Company's initial public offering in January 1997, the
Stockholders' Agreement was terminated and the dividend payable was paid (see
note 8(h)).

  (e) Certain Common Stock Transactions
 
     In July 1994, 116,928 shares of common stock held in treasury were issued
to a stockholder in exchange for an unsecured promissory note of $75,000. The
note bore interest at 8.25% and was payable in three annual installments of
$25,000 each through 1997. A total of $39,000 was repaid on the note and the
remaining balance of $36,000 was forgiven in 1996 as consideration for entering
into a new employment agreement.
 
  (f) Warrants
 
     In 1993, the Company obtained $300,000 in financing through the issuance of
6% convertible unsecured promissory notes with attached warrants to acquire the
Company's common stock. Because the exercise price of the attached warrants
exceeded the fair value of the common stock, the Company allocated the $300,000
of proceeds to notes payable. The notes were convertible into the Company's
Series A CPS at a conversion price of $1.00 per share. In 1994, the notes
payable of $300,000 and accrued interest of $18,000 were converted into 318,000
shares of the Company's Series A CPS. The common stock purchase warrants give
the holders the right to acquire 194,880 shares of the Company's common stock at
an exercise price of $1.54 per share. The common stock purchase warrants expire
on June 23, 1998.
 
     Also, as discussed in note 5, in March 1996, the Company issued to HPSC
warrants to purchase 298,150 shares of the Company's common stock at an exercise
price of $.015 per share. The common stock purchase warrants were exercised
subsequent to December 31,1997.
 
  (g) Common Stock Reverse Split
 
     In December 1996, the Company's Board of Directors approved an amendment to
its certificate of incorporation which effected a 0.6496-for-one reverse stock
split. All references to common stock, stock options, and warrants in these
consolidated financial statements have been adjusted to reflect this amendment
as if it had occurred prior to January 1, 1995.
 
  (h) Initial Public Offering
 
     On January 31, 1997, the Company sold 2,300,000 shares of its common stock
in an initial public offering in which it received approximately $22,626,000,
net of offering expenses of approximately $750,000. As a result of the
consummation of the offering, the Series A CPS and Series B CPS were converted
into 1,021,809 shares of common stock of the Company, the HPSC Agreement was
terminated, and the Stockholders' Agreement was terminated. In addition, all of
the Company's dividends payable and debt, excluding obligations under capital
leases, were repaid.
 
(9) MAJOR CUSTOMER
 
     For the years ended December 31, 1997, 1996 and 1995, one customer
accounted for approximately 16%, 15%, and 9%, respectively, of total revenues.
 
(10) NOTE RECEIVABLE FROM OFFICER
 
     In June 1996, the Company loaned $112,500 to an officer of the Company in
the form of an unsecured promissory note. The note is to be repaid in five equal
annual installments of $22,500 each, due and payable on the first through fifth
anniversaries of the date of the note. Interest accrues at a rate of 8.25% per
annum and is due and payable by the officer on the date each principal payment
is due. The first annual installment of $22,500 was paid in June 1997.

The Board of Directors and Shareholders
Medirisk, Inc.
 
     Under date of February 6, 1998, we reported on the consolidated balance
sheets of Medirisk, Inc. and subsidiaries as of December 31, 1997 and 1996, and
the related consolidated statements of operations, stockholders' equity
(deficit), and cash flows for each of the years in the three-year period ended
December 31, 1997, as contained in the annual report on Form 10-K for the year
1997. In connection with our audits of the aforementioned consolidated financial
statements, we also audited the related consolidated financial statement
schedule included in the annual report on Form 10-K for the year 1997. This
financial statement schedule is the responsibility of the Company's management.
Our responsibility is to express an opinion on this financial statement schedule
based on our audits.
 
     In our opinion, such financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

                                  CAPITAL STOCK

         SECTION 1.1. CERTIFICATES. Every holder of stock in the Corporation
shall be entitled to have a certificate signed in the name of the Corporation by
the Chairman of the Board of Directors or the President or a Vice President, and
by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant
Secretary of the Corporation certifying the number of shares in the Corporation
owned by such holder. If such certificate is countersigned (a) by a transfer
agent other than the Corporation or its employee, or, (b) by a registrar other
than the Corporation or its employee, any other signature on the certificate may
be a facsimile. In case any officer, transfer agent, or registrar who has signed
or whose facsimile signature has been placed upon a certificate shall have
ceased to be such officer, transfer agent, or registrar before such certificate
is issued, it may be issued by the Corporation with the same effect as if such
person were such officer, transfer agent, or registrar at the date of issue.

         SECTION 1.2. RECORD OWNERSHIP. A record of the name and address of the
holder of each certificate, the number of shares represented thereby and the
date of issue thereof shall be made on the Corporation's books. The Corporation
shall be entitled to treat the holder of record of any share of stock as the
holder in fact thereof, and accordingly shall not be bound to recognize any
equitable or other claim to or interest in any share on the part of any other
person, whether or not it shall have express or other notice thereof, except as
required by the laws of the State of Delaware.




<PAGE>   4


         SECTION 1.3. TRANSFER OF RECORD OWNERSHIP. Transfers of stock shall be
made on the books of the Corporation only by direction of the person named in
the certificate or such person's attorney, lawfully constituted in writing, and
only upon the surrender of the certificate therefor and a written assignment of
the shares evidenced thereby, which certificate shall be canceled before the new
certificate is issued.

         SECTION 1.4. LOST CERTIFICATES. Any person claiming a stock certificate
in lieu of one lost, stolen or destroyed shall give the Corporation an affidavit
as to such person's ownership of the certificate and of the facts which go to

otherwise not in accordance with law, or is not appropriate for consideration at
that meeting based on valid considerations (including that the Stockholder
Proposal was not included in the proxy statement distributed to stockholders in
connection with the meeting), and if so determined, such officer shall so
declare at the meeting and the Stockholder Proposal shall be disregarded.

         (b) Only persons who are selected and recommended by the Board of
Directors or the committee of the Board of Directors designated to make
nominations, or who are nominated by stockholders in accordance with the
procedures set forth in this Section 2.7, shall be eligible for election, or

employment during such period, the name and principal business of any

more of any class of capital stock, partnership interests or other equity
interest of any corporation, partnership or other entity; (D) any directorships
held by such nominee in any company with a class of securities registered
pursuant to Section 12 of the Securities Exchange Act of 1934, as amended, or
subject to the requirements of Section 15(d) of such Act or any company
registered as an investment company under the Investment Company Act of 1940, as
amended; and (E) whether, in the last five years, such nominee has been
convicted in a criminal proceeding or has been subject to a judgment, order,
finding or decree of any federal, state or other governmental entity, concerning
any violation of federal, state or other law, or any proceeding in bankruptcy,
which conviction, order, finding, decree or proceeding may be material to an
evaluation of the ability or integrity of the nominee; and (ii) as to the person
submitting the Nomination Notice and any person acting in concert with such
person, (x) the name and business address of such person, (y) the name and
address of such person as they appear on the Corporation's books (if they so
appear), and (z) the class and number of shares of the Corporation that are
beneficially owned by such person. A written consent to being named in a proxy
statement as a nominee, and to serve as a director if elected, signed by the
nominee, shall be filed with any Nomination Notice. If the presiding officer at
any stockholders' meeting determines that a nomination was not made in
accordance with the procedures prescribed by these Bylaws, he shall so declare
to the meeting and the defective nomination shall be disregarded.

         (c) Nomination Notices and Stockholder Proposals shall be delivered to
the Secretary at the principal executive office of the Corporation 60 days or
more before the date of the stockholders' meeting if such Nomination Notice or
Stockholder Proposal is to be submitted at an

Directors shall be decided by a plurality of the votes cast and all other
questions shall be decided by a majority of the votes cast, except as otherwise

inspector or inspectors may include individuals who serve the Corporation in
other capacities, including, without limitation, as officers, employees, agents
or representatives of the Corporation, to act at the meeting and make a written
report thereof. One or more persons may be designated by the Board of Directors
as alternate inspectors to replace any inspector who fails to act. If no
inspector or alternate is able to act at a meeting of stockholders, the chairman
of the meeting shall appoint one or more inspectors to act at the meeting. Each
inspector, before discharging his or her duties, shall take and sign an oath
faithfully to execute the duties of inspector with strict impartiality and
according to the best of his or her ability. The inspectors shall have the

         SECTION 3.1. MANAGEMENT. The business and affairs of the Corporation
shall be managed by or under the direction of its Board of Directors.

         SECTION 3.2.  NUMBER; QUALIFICATION; ELECTION; TERM.

         (a) The number of directors constituting the Board of Directors shall
not be less than three, nor more than twelve, the exact number to be determined
by a vote of the majority of the Directors then in office. The directors of the
Corporation (exclusive of any directors who are elected pursuant to the terms of
, and serve as representatives of the holders of, any series of preferred stock
of the Corporation) shall be referred to herein as "Classified Directors" and
shall be divided into three classes, with the first class referred to herein as
"Class 1," the second class as "Class 2," and the third class as "Class 3." If
the total number of Classified Directors equals a number divisible by three,
then the number of directors in each of Class 1, Class 2 and Class 3 shall be
that number of directors equal to the total number of directors divided by
three. If, however, the total number of Classified Directors equals a number
that is not divisible by three, each such class of directors shall consist of
that number of directors as nearly equal in number as possible to the total
number of directors divided by three, as determined by the Board of Directors in
advance of each respective election of directors by holders of shares of capital
stock of the Corporation then entitled to vote in such election. The term of
office of the initial Class 1 directors shall expire at the 1997 annual meeting
of stockholders, the term of office of the initial Class 2 directors shall
expire at the 1998 annual meeting of stockholders, and the term of office of the
initial Class 3 directors shall expire at the 1999 annual meeting of
stockholders, with each director to hold office until his successor shall have
been duly elected and qualified. At each annual meeting of stockholders,
commencing with the 1997 annual meeting, directors elected to succeed those
directors whose terms then expire shall be elected for a term of office to
expire at the third succeeding annual meeting of stockholders after their
election, with each director to hold office until his successor shall have been
duly elected and qualified..

<PAGE>   11

         (b) Notwithstanding the foregoing, whenever the holders of any one or
more classes or series of preferred stock issued by the Corporation shall have
the right, voting separately by series or by class (excluding holders of common
stock), to elect directors at an annual or special meeting of stockholders, the
election, term of office, filling of vacancies, and other features of such
directorships shall be governed by the terms of the Certificate of Incorporation
including any amendment to the Certificate of Incorporation that designates a
series of preferred stock) and such directors so elected by the holders of
preferred stock shall not be divided into classes pursuant to this Section 3.2
unless expressly provided by the terms of the Certificate of Incorporation.

         SECTION 3.3. VACANCIES. Any or all Classified Directors may be removed
for cause at any annual or special meeting of stockholders, upon the affirmative
vote of the holders of a majority of the outstanding shares of each class of
capital stock then entitled to vote in person or by proxy at an election of such
Classified Directors, provided that notice of the intention to act upon such
matter shall have been given in the notice calling such meeting. Newly created
directorships resulting from any increase in the authorized number of Directors
and any vacancies occurring in the board of directors caused by death,
resignation, retirement, disqualification, removal or other termination from
office of any directors may be filled by the vote of a majority of the Directors
then in office, though less than a quorum, or by the affirmative vote, at a
special meeting of the stockholders called for the purpose of filling such
directorship, of the holders of a majority of the outstanding shares of capital
stock then entitled to vote in person or by proxy at such meeting. Each
successor directors so chosen shall hold office until the next election of the
class for which such director shall have been chosen and until his respective
successor shall have been duly elected and qualified. Any newly created or
eliminated directorships resulting from an increase or decrease in the
authorized number of directors shall be appointed or allocated by the Board of
Directors among the three classes of directors so as to maintain such classes as
nearly equal in number as possible.

specification, it shall take effect upon the receipt thereof.

         SECTION 3.5. REGULAR MEETINGS. Regular meetings of the Board of
Directors may be held without further notice at such time and such place as

is provided and one third of the members of the Board of Directors then in
office object in writing prior to or at the commencement of the meeting, such
meeting shall be postponed until five (5) days after such notice was given
pursuant to this sentence (or such shorter period to which a majority of those
who objected in writing agree), provided that notice of such postponed meeting
shall be given in accordance with this Section 3.7. The notice of the special
meeting shall state the general purpose of the meeting, but other routine
business may be conducted at the special meeting without such matter being
stated in the notice.

the Board of Directors. Whether or not a quorum is present to conduct a meeting,
any meeting of the Board of Directors (including an adjourned meeting) may be

time and place. It shall not be necessary to give to the directors present at
the adjourned meeting notice of the reconvened meeting or of the business to be
transacted, other than by announcement at the meeting that was adjourned;
provided, however, notice of such reconvened meeting, stating the date, time,

Corporation to be made by such mechanical means or stamps as any of such
officers may deem appropriate.

         SECTION 5.17. APPOINTMENT OF OFFICERS AND AGENTS. The Chief Executive
Officer may appoint one or more Vice Presidents and such other officers,
assistant officers and agents as the Chief Executive Officer may determine. Any
such officers, assistant officers or agents so appointed shall perform such

Executive Officer, and, unless the Chief Executive Officer otherwise directs,
such appointed officers and assistant officers shall perform such duties as are
generally performed by officers or assistant officers with equivalent
restrictions, if any, on title and shall have such other powers as may from
time-to-time be delegated by the Board of Directors.

                                   SECTION VI

                                 INDEMNIFICATION

         SECTION 6.1. INDEMNIFICATION PROVISIONS IN CERTIFICATE OF
INCORPORATION. The provisions of this Section VI are intended to supplement
Article VI of the Certificate of Incorporation pursuant to Sections 6.2 and 6.3
thereof. To the extent that this Section VI contains any provisions inconsistent
with said Article VI, the provisions of the Certificate of Incorporation shall
govern. Terms defined in such Article VI shall have the same meaning in this
Section VI.

         SECTION 6.2. INDEMNIFICATION OF EMPLOYEES. The Corporation shall
indemnify and advance expenses to its employees to the same extent as to its
directors and officers, as set forth in the Certificate of Incorporation and in
this Section VI of the Bylaws of the Corporation.

         SECTION 6.3. UNDERTAKINGS FOR ADVANCES OF EXPENSES. If and to the
extent the Delaware General Corporation Law requires, an advancement by the
Corporation of expenses incurred by an indemnitee pursuant to clause (iii) of
the last sentence of Section 6.1(b) of the Certificate of Incorporation
(hereinafter an "advancement of expenses") shall be made only upon delivery to
the Corporation of an undertaking (hereinafter an "undertaking"), by or on
behalf of 


                                      -16-

<PAGE>   19

such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal (hereinafter a "final adjudication") that such indemnitee is not entitled
to be indemnified for such expenses under Article VI of the Certificate of
Incorporation or otherwise.

         SECTION 6.4. CLAIMS FOR INDEMNIFICATION. If a claim for indemnification
under Section 6.1 of the Certificate of Incorporation is not paid in full by the
Corporation within sixty (60) days after it has been received in writing by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty (20) days, the indemnitee may
at any time thereafter bring suit against the Corporation to recover the unpaid
amount of the claim. If successful in whole or in part in any such suit, or in a
suit brought by the Corporation to recover an advancement of expenses pursuant
to the terms of an undertaking, the indemnitee shall be entitled to be paid also
the expense of prosecuting or defending such suit. In any suit brought by the
indemnitee to enforce a right to indemnification hereunder (but not in a suit
brought by the indemnitee to enforce a right to an advancement of expenses) it
shall be a defense that, and in any suit by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking the Corporation
shall be entitled to recover such expenses only upon a final adjudication that,
the indemnitee has not met the applicable standard of conduct set forth in
Section 145 of the Delaware General Corporation Law (or any successor provision
or provisions). Neither the failure of the Corporation (including the Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such suit that indemnification of the
indemnitee is proper in the circumstances because the indemnitee has met the
applicable standard of conduct set forth in Section 145 of the Delaware General
Corporation Law (or any successor provision or provisions), nor an actual
determination by the Corporation (including the Board of Directors, independent
legal counsel, or its stockholders) that the indemnitee has not met such
applicable standard of conduct, shall create a presumption that the indemnitee
has not met the applicable standard of conduct or, in the case of such a suit
brought by the indemnitee, be a defense to such suit. In any suit brought by the


                                      -17-

<PAGE>   20

indemnitee to enforce a right to indemnification or to an advancement of
expenses hereunder, or by the Corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the burden of proving that the
indemnitee is not entitled to be indemnified, or to have or retain such
advancement of expenses, under Article VI of the Certificate of Incorporation or
this Section VI or otherwise, shall be on the Corporation.

         SECTION 6.5. INSURANCE. The Corporation may maintain insurance, at its
expense, to protect itself and any director, trustee, officer, employee or agent
of the Corporation or another enterprise against any expense, liability or loss,
whether or not the Corporation would have the power to indemnify such person
against such expense, liability or loss under the Delaware General Corporation
Law.

         SECTION 6.6. SEVERABILITY. In the event that any of the provisions of
this Section VI (including any provision within a single section, paragraph or
sentence) is held by a court of competent jurisdiction to be invalid, void or
otherwise unenforceable, the remaining provisions are severable and shall remain
enforceable to the full extent permitted by law.

                                   SECTION VII

                                  MISCELLANEOUS

         SECTION 7.1. SEAL. The Corporation shall have a suitable seal,
containing the name of the Corporation. The Secretary shall be in charge of the
seal and may authorize one or more duplicate seals to be kept and used by any
other officer or person.

         SECTION 7.2. WAIVER OF NOTICE. Whenever any notice is required to be
given, a waiver thereof in writing, signed by the person or persons entitled to
the notice, whether before or after the time stated therein shall be deemed
equivalent thereto. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.


                                      -18-

<PAGE>   21

         SECTION 7.3. VOTING OF STOCK OWNED BY THE CORPORATION. Powers of
attorney, proxies, waivers of notice of meeting, consents and other instruments
relating to securities owned by the Corporation may be executed in the name of
and on behalf of the Corporation by the Chairman of the Board, the President,
any Vice President or such officers or employees or agents as the Board of
Directors or any of such designated officers may direct. Any such officer may,
in the name of and on behalf of the Corporation, take all such action as any
such officer may deem advisable to vote in person or by proxy at any meeting of
security holders of any corporation in which the Corporation may own securities
and at any such meeting shall possess and may exercise any and all rights and
powers incident to the ownership of such securities and which, as the owner
thereof, the Corporation might have exercised and possessed if present. The
Board of Directors may from time to time confer like powers upon any other
person or persons.

                                  SECTION VIII

                               AMENDMENT OF BYLAWS

         The Board of Directors, by the affirmative vote of a majority of the
whole Board of Directors, shall have power to amend, alter, change, adopt or
repeal the Bylaws of the Corporation at any regular or special meeting;
provided, however, that the stockholders entitled to vote may prescribe that any
Bylaw adopted by the stockholders may not be amended, altered, changed or
repealed by the Board of Directors. The stockholders entitled to vote also shall
have the power to amend, alter, change, adopt or repeal the Bylaws of the
Corporation at any annual or special meeting subject to the requirements of the
Certificate of Incorporation.

                    FORMATIONS(SM) CLINICAL OUTCOMES SYSTEMS

                         LICENSE AND SERVICES AGREEMENT


         THIS LICENSE AND SERVICES AGREEMENT is made and entered into as of the
19th day of December 1997, by and between MEDIRISK OF ILLINOIS, INC., an Indiana
corporation ("Medirisk"), and HEALTHSOUTH CORPORATION, a Delaware corporation
("Licensee").


                                   BACKGROUND:

         Medirisk has developed proprietary systems (collectively, the
"Systems," as more particularly hereinafter defined), whereby Medirisk compiles
and analyzes various types of information supplied to Medirisk by its customers
concerning the healthcare-related services and programs offered by each such
customer, and provides to each such customer reports and other materials which
allows the customer to compare the efficiency and effectiveness of the outcome
of its services and programs against national norms and/or its own performance
at its various facilities. Licensee desires to license from Medirisk for its use
certain products and services which constitute or are a part of the Systems. In
addition, as a material inducement to Licensee to enter into this Agreement,
Medirisk represents and warrants to Licensee that the Systems have been
determined by the Joint Commission on Accreditation of Healthcare Organizations
("JCAHO") to meet the initial criteria for inclusion in JCAHO's future
accreditation process and have been included in JCAHO's initial list of
acceptable clinical performance measurement systems for use in meeting JCAHO
accreditation requirements for healthcare organizations. Medirisk is committed
to meeting future criteria established by JCAHO in this regard. JCAHO requires
that organizations seeking JCAHO accreditation select clinical performance
measures that together represent at least 20% of the organization's identified
patient population, and that in future years the requirements for the number of
measures and the percentage of the represented population will increase.
Medirisk has created various Performance Measures (the "Measures") which
correspond to the Instruments (as hereinafter defined) that comprise the
Systems. Licensee desires to obtain JCAHO accreditation for each of its
Applicable Facilities (as hereinafter defined), and to use one or more of the
Measures for clinical performance measurement purposes in this regard.

         Medirisk acknowledges that due to Licensee's size and the volume and
breadth of services which Medirisk has previously provided to Licensee, Licensee
and Medirisk have been and will continue to be in a unique client-provider
relationship. In this regard, the overall scope of services to be performed for
Licensee are also unique to Licensee, and the parties have entered into the
attached Statement of Work to better describe the undertakings of both parties
under this Agreement.

         NOW, THEREFORE, for and in consideration of the mutual undertakings of
the parties hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereby
agree as follows:

1.0      DEFINITIONS. For purposes of this Agreement, the following terms shall

         Instrumental Activities of Daily Living ("IADL") and Comorbid Disease
         Status Instruments, as well as in and to the General Rehabilitation,
         Medical and Orthopedic Outcomes Instruments. Notwithstanding the

         measure or the Rancho Los Amigos Level of Cognitive Function Instrument
         Rating. It is hereby agreed between the parties that nothing within the

         2.3      SCOPE OF LICENSE. This Agreement and license shall extend to

         completed Facility Enrollment Confirmation signed by both a
         representative of Licensee's corporate office and a representative of
         the facility. The Facility Enrollment Confirmation for a particular
         facility shall be prepared by Medirisk and sent to Licensee for review
         and signature after Medirisk has received from Licensee the completed
         Facility Enrollment Form for such facility, and shall set forth all of
         the pertinent information disclosed in the Facility Enrollment Form for
         such facility. The completed Facility Enrollment Form shall indicate
         which Clinical Ratings Instruments that are a part of the Selected
         System are to be available for use at such facility, as well as such
         other information as may be requested in the form. Should Licensee
         subsequently wish to extend this Agreement and license to apply to
         additional facilities of Licensee, Licensee shall pay the license fee
         per Applicable Facility as required in Section 4.1 hereof, provide
         Medirisk with a completed Facility Enrollment Form for each such
         additional facility, and have the resulting Facility Enrollment
         Confirmation reviewed, executed and returned to Medirisk.

         2.4      DUTY NOT TO DISCLOSE. Licensee shall not transfer, provide or

         or form provided to it by Medirisk under the license granted herein.
         Licensee shall not copy (whether by means of photocopying or otherwise)
         any Training Manuals or forms. The foregoing restrictions shall not
         apply where compliance with the order of a judicial or administrative
         authority requires such items to be so disclosed, provided that in such
         event Licensee shall provide Medirisk with prompt written (or if not
         practicable to do so, oral) notice of such action so that Medirisk may
         seek to obtain an appropriate protective order.

         2.5      SOURCE ACKNOWLEDGMENT. If Licensee or any facility or employee
         thereof reproduces or otherwise uses, in any document prepared by
         Licensee, for any purpose, excerpts or data from Facility Outcomes
         Reports or custom reports or analysis provided by Medirisk to Licensee,
         including but not limited to purposes of marketing, contracting, public
         relations, or any other external purpose, Licensee shall in such
         document expressly acknowledge and disclose Medirisk as the source of
         such information by inserting the following language in a conspicuous
         location in said document(s): "Certain data reproduced herein has been
         compiled and analyzed by Medirisk of Illinois, Inc., in connection with
         the author's utilization of the FORMATIONS(SM) Clinical Outcomes
         Systems."

         2.6      ASSIGNMENT. Neither party may assign, transfer, sell, donate,
         pledge as security, license or sublicense this Agreement or any of its
         rights or obligations hereunder, in whole or in part, by operation of
         law or change in control of such party or otherwise, other than to an
         affiliate thereof, without the prior written consent of the other party
         hereto; provided, however, that the foregoing restrictions on pledging
         as security and change in control shall not apply to Medirisk. Licensee
         may not rent, sublease, sell, loan, or otherwise transfer all or any of
         the System, except as expressly provided in this Agreement.

         2.7      SURVIVABILITY OF CERTAIN OBLIGATIONS. The obligation of
         Licensee under Sections 2.4, 2.5 and 2.6 hereof shall survive and
         remain binding upon Licensee after the termination of this Agreement.

3.0      TERM.

         3.1      INITIAL TERM OF AGREEMENT. This Agreement shall have an
         initial term of three (3) years, commencing 1January 1998 and expiring
         31 December 2000. The foregoing expiration date shall apply to all
         Applicable Facilities, without extension (other than renewal as
         hereinafter set forth), whether currently or subsequently enrolled and
         regardless of the date Licensee submits a completed and fully signed
         Facility Enrollment Confirmation for such facility.

         3.2      RENEWAL TERMS. This Agreement shall automatically renew for
         successive terms of one (1) year each upon the expiration of the
         initial or any renewal term hereof unless written notice of nonrenewal
         is given by either party to the other not less than ninety (90) days
         prior to the initial expiration or applicable renewal date. Upon not
         less than one hundred fifty (150) days' written notice given prior to
         the initial expiration or any applicable renewal date of this
         Agreement, Medirisk may increase any of the fees and/or charges payable
         hereunder to those set forth in such notice, effective upon such
         initial expiration or renewal date, and should Licensee not find such
         increase(s) acceptable, Licensee may elect not to renew this Agreement
         by following the procedure set forth in this Section 3.2.

         3.3      RETURN OF LICENSED ITEMS. Upon the expiration of this
         Agreement (or earlier termination hereof for any reason), Licensee
         shall, within ten (10) days after the date of expiration or termination
         and receipt of a written request from Medirisk, certify to Medirisk in
         writing that all unused Data Collection Forms and Training Manuals such
         items have been destroyed and that Licensee retains none of such
         materials or copies therof.

4.0      LICENSE FEES AND OTHER PAYMENTS.

         4.2      [Intentionally Omitted.]

         4.3      [Intentionally Omitted.]

         4.4      [Intentionally Omitted.]

         4.5      TAXES. Any sales or excise tax due on the provision of the
         Selected System and/or optional products and/or services hereunder to
         Licensee shall be the sole responsibility of Licensee.

         4.6      PAYMENT. Fees shall be due and payable hereunder as set forth
         in Schedule 1 attached hereto. Except with respect to any initial
         payments due hereunder, Medirisk shall invoice Licensee for fees due
         hereunder not less than thirty (30) days prior to their respective due
         dates. Fees not received by such due dates will be considered late and
         subject to the late charge set forth in Section 4.7 hereof,
         notwithstanding the 30-day grace period set forth therein. With respect
         to any other payments due to Medirisk hereunder, payment terms are net
         thirty (30) days from the date of the invoice unless otherwise agreed
         upon in writing by Medirisk.

         4.7      LATE CHARGES. If Licensee fails to pay any amount when due and
         payable, and any such amount due remains outstanding for more than ten
         (10) days after written notice of nonpayment by Medirisk to Licensee,
         Licensee agrees that any amount not paid shall bear interest from the
         original due date until paid at the lesser of one and one-half (1.5%)
         percent per month or the highest rate allowed by applicable law. This
         late payment charge will not apply to any unpaid amounts relating
         directly to a good faith dispute between Medirisk and Licensee.
         However, such disputes shall not permit Licensee to withhold or offset
         any payments not directly related to the invoice or amount in dispute,
         except with respect to any amounts which Licensee may have
         inadvertently overpaid to Medirisk.

5.0      DISCLAIMER OF WARRANTIES. Licensee recognizes and acknowledges that the
data contained in the National Database of Outcomes Data is collected from
sources believed to be reliable, and that, although Medirisk believes the data
to be accurate, MEDIRISK MAKES NO WARRANTIES OR REPRESENTATIONS OF ANY TYPE
CONCERNING THE SYSTEM, ITS CONSTITUENT PARTS OR ANY OTHER PRODUCTS OR SERVICES
OFFERED HEREUNDER, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
Notwithstanding the foregoing, Medirisk warrants that, assuming submission of
materially complete and materially error-free data to Medirisk by Licensee, the
work product prepared by Medirisk hereunder will be materially error-free.

6.0      LIMITATION OF LIABILITIES. In no event shall Medirisk's liability for
any direct damages, regardless of the form of action, exceed two and one-half
(2.5) times the fee paid by Licensee hereunder for use of the System. Under no
circumstances shall Medirisk be liable for incidental, consequential, special or
exemplary damages of any kind, or for lost profits arising out of the use or
inability to use the System, even if such damages were foreseeable at the time
of execution of this Agreement. Notwithstanding the foregoing, there shall be no
limitation of liability for damages caused by or arising out of (i) Medirisk's
failure to maintain the confidentiality of Licensee's data as set forth in
Section 9.5 hereof, or (ii) the indemnification obligation of Medirisk set forth
in Section 2.2 hereof (concerning proprietary rights).

7.0      PROPRIETARY INFORMATION.

         7.1      THE SYSTEMS. The Systems are proprietary to Medirisk and is
         provided under license and subscription to healthcare facilities
         whereby each facility's staff are trained and certified in the use of
         Clinical Rating Instruments for monitoring patient conditions. Medirisk
         provides its licensees with Facility Outcomes Reports for use in
         evaluating program effectiveness and efficiency and comparison of those
         results to like programs and patient populations. The Systems include
         the following Instruments (the Comorbid Disease Status Instrument
         comprising a part of every Instrument; General Rehabilitation Outcomes
         Instruments; and the functional independence measure instrument
         comprising a part of the Medical and General Rehabilitation Outcomes
         Instruments):

                  (A) Medical Outcomes: Consisting of Rehabilitation (functional
         independence measure, IADL, and Rancho Los Amigos Level of Cognitive
         Function Instrument Rating), Infection, Nutrition, Pain Treatment,
         Respiratory Treatment and Wound Treatment Instruments; and

                  (B) General/Customized Rehabilitation Outcomes.

         7.2      MEDIRISK UPDATE AND MODIFICATION. Medirisk expressly retains
         the right, in its sole discretion, to update or modify any of its
         proprietary Instruments or the Systems at any time and provide Licensee
         with written notice of such update or modification. Should Medirisk
         deem it appropriate, Medirisk will provide Licensee's facility(ies)
         with appropriate documentation and support material and/or
         re-certification workshops for all Certified Raters using said
         Instruments or Systems at no cost to Licensee, if said update or
         modification occurs during the first eighteen (18) months of the term
         hereof. In the event that the System as so updated or modified (i) is
         no longer materially suitable for use by Licensee or (ii) would result
         in out-of-pocket training and/or re-certification expenses in excess of
         $100,000.00, then, upon not less than sixty (60) days written notice to
         Medirisk, Licensee may terminate this Agreement without penalty.

         7.3      MODIFICATION BY LICENSEE. Licensee may not modify, reformat,
         manipulate, translate, adapt or reverse engineer the Systems or any
         component or constituent part thereof for any purpose, or rent,
         sublease, sell, loan, or otherwise transfer all or any of the Systems,
         except as expressly provided in this Agreement.

8.0      CERTIFICATION PROGRAM GUIDELINES. The Certification Program is designed
to ensure that staff employed by Licensee at its Applicable Facilities
adequately understand and uniformly apply to the Instruments and rating
guidelines so that Licensee's data is internally consistent and Licensee's
gathering of data is consistent with the gathering of data by other licensees of
Medirisk and thereby eligible for entry into the National Database of Outcomes
Data. The Certification Program is controlled and managed solely by Medirisk for
the purposes and anticipated results as Medirisk may in its sole discretion deem
appropriate. Licensee acknowledges that no authority other than Medirisk, either
public or private, mandates or supervises the Certification Program. Licensee
agrees to participate in the Certification Program and take all steps required
thereby. Licensee may use a different certification system only after it has
been submitted to Medirisk in writing, and Medirisk, in its sole discretion, has
approved the proposed alternative in writing. Until any alternative is approved
by Medirisk and authorized in writing, Licensee agrees to conform to the
Certification Program.

         8.1      CANDIDATES FOR THE CERTIFICATION PROGRAM. No person other than
         a Rater Candidate may become certified to rate patients without the
         written consent of Medirisk. The term "Rater Candidate" shall refer to
         any member of Licensee's staff at an Applicable Facility who holds one
         of the positions designated below for the indicated Applicable
         Instrument(s):

                  (A)      Medical Outcomes Instruments: Registered Nurse
                           ("RN"), Licensed Practical Nurse under direct
                           supervision of an RN ("LPN"), physician or
                           Respiratory Therapist.

                  (B)      Functional independence measure, IADL, Rancho Los
                           Amigos Level of Cognitive Function Instrument Rating,
                           and General Rehabilitation Outcomes Instrument:
                           Licensed Physical Therapist ("PT"), Licensed
                           Occupational Therapist ("OTR"), Licensed Therapy
                           Assistant ("TA"), Licensed Speech Pathologist ("SP"),

         8.2      MEDIRISK CLINICAL RATER. A Rater Candidate who has passed the
         Certification Program agreed to by the parties with respect to a
         particular Instrument, is a Certified Clinical Rater as to that
         Instrument.

         8.3      CERTIFICATION PROGRAM OPERATION.  See Statement of Work.

         8.4      MEDIRISK'S CERTIFICATION STANDARD. To become a Certified
         Clinical Rater, a Rater Candidate must correctly answer a minimum of
         eighty (80%) percent of all questions comprising Medirisk's
         certification test. A Rater Candidate must be separately tested for
         each Instrument selected by Licensee in Schedule 1.

9.0      DATA SUBMISSION.

         9.1      DATA SUBMISSION SCHEDULE. Licensee shall submit data to
         Medirisk within ten (10) days after the end of the monthly
         data-gathering period. Licensee recognizes that failure to provide data
         in a timely manner will interfere with Medirisk's ability to provide
         Licensee with timely reports and will neither interrupt Medirisk's
         invoicing cycle or Licensee's corresponding payment obligations, nor
         extend the term of this Agreement. Further data submission requirements
         are set forth in the Statement of Work.

         9.2      DATA SUBMISSION VEHICLE. All data submission will in the HCIS
         (or successor software system) format (see Statement of Work).

         9.3      DATA SUBMISSION FORMAT. Licensee shall ensure that all data
         fields are complete for each patient rating and submission. Licensee
         acknowledges that incomplete or inaccurate data may skew reports. If
         Medirisk's data error process indicates that data is incomplete or
         inaccurate, Licensee may be requested to provide additional data;
         failure of Licensee to timely submit such data may result in a delay in
         the production of applicable reports, which delay shall not be
         actionable by Licensee. In order to facilitate data submission,
         Licensee agrees to assign a staff member at each facility to the role
         of Data Collection Coordinator with respect to Medirisk. This staff
         member shall have primary responsibility for, and primary contact with
         Medirisk regarding, data submission. Licensee agrees to provide the
         name, telephone, and fax numbers of each such person to Medirisk via
         each completed Facility Enrollment Form. Licensee agrees to reassign
         this responsibility to another staff member, when appropriate, and to
         use good faith efforts to promptly inform Medirisk of each such change.
         Medirisk shall likewise identify to each Data Collection Coordinator
         his or her primary contact at Medirisk, along with such person's
         telephone and fax numbers.

         9.4      DATA INTEGRITY. Licensee shall ensure, and hereby warrants,
         that:

                  (A)      facility patients will be asked to complete
                           questionnaires and all data collected by Licensee
                           will be collected by Certified Raters in accordance
                           with the written protocol set forth in the Training
                           Manual;

                  (B)      data will be collected on all patients who are in a
                           treatment program pertinent to each Applicable
                           Instrument for each Applicable Facility;

                  (C)      no data will be intentionally falsified or distorted
                           for any reason; and

                  (D)      Certified Raters will enter their own identification
                           number for each patient rating and data will be
                           accepted only if taken by Certified Raters.

         9.5      DATA CONFIDENTIALITY; PERMITTED DISCLOSURES AND USE OF DATA.
         Medirisk shall maintain a copy of all data collected from the
         Applicable Facilities, unless otherwise requested in writing by
         Licensee, and shall maintain the confidentiality of such data. Such
         data shall include, without limitation, information obtained by
         Medirisk as a result of the follow-up telephone surveys with patients
         which may be conducted by Medirisk as discussed in the Statement of
         Work, or similar inquiries performed by Medirisk. All data collected
         from the Applicable Facilities, as well as the results set forth in any
         report prepared by Medirisk for Licensee using such data, shall be and
         remain the confidential property of Licensee. Notwithstanding the
         foregoing, Licensee agrees that any data which it submits to Medirisk,
         or which



                                      -7-
<PAGE>   9


         Medirisk otherwise obtains from or on behalf of Licensee, may be
         entered into the National Database of Outcomes Data, at Medirisk's
         discretion, and that Medirisk may use and/or otherwise provide data to
         third parties from the National Database of Outcomes Data, at
         Medirisk's discretion; provided, however, that Medirisk may only
         disclose such data to third parties in a fashion that does not reveal
         the identity of the individual patient or facility which provided such
         data, except to research organizations or consultants pursuant to a
         data utilization confidentiality or similar agreement to which Medirisk
         and any such research organization or consultant are parties, and in
         such case the name of the patient and facility will either be omitted
         or encrypted. Pursuant to the terms of such data utilization
         confidentiality agreement, such research organizations and consultants
         will generally be prohibited from further disclosing the identities of
         individual facilities and patients, subject to such exceptions
         permitting limited disclosure as Medirisk in its reasonable discretion
         may negotiate with such research organizations or consultants. Licensee
         will request a release from each patient for such actions, including an
         acknowledgment and consent by the patient that he or she may be the
         subject of a follow-up telephone survey(s), and that he or she will
         cooperate in providing the requested information; provided, however,
         that nothing in this Agreement or otherwise shall require a patient to
         so consent nor shall the failure of one or more patients to so consent
         be deemed a default by Licensee hereunder. A form of suggested language
         to incorporate into such a release is attached hereto as Schedule 3;
         provided, however, that Medirisk's provision of this language to
         Licensee is and shall be expressly subject to the disclaimer set forth
         in said Schedule. Licensee shall indemnify, defend and hold Medirisk
         harmless from and against any third party claim, demand, suit or
         actions brought at any time with regard to Medirisk's use of such data
         in accordance with the terms and provisions of this Agreement. Medirisk
         shall indemnify, defend and hold Licensee harmless from and against any
         third party claim, demand, suit or actions brought at any time with
         regard to Medirisk's use of such data which is not in accordance with
         the terms and provisions of this Agreement. Medirisk's and Licensee's
         indemnification and defense obligation as herein set forth shall
         survive and remain respectively binding upon them after the termination
         of this Agreement for any reason.

10.0     OUTCOMES REPORTS. Medirisk shall provide reports as set forth in the
Statement of Work.

11.0     SUPPORT AND CONSULTATION. Medirisk shall provide Licensee with support
and consultation as set forth in the Statement of Work.

12.0     JCAHO.

         12.1     SELECTED PERFORMANCE MEASURES. Licensee shall complete a
         Performance Measure Designation for each Applicable Facility and submit
         it to Medirisk and shall therein designate the two (2) Measures
         indicated therein as the initial clinical performance measures for
         JCAHO accreditation of such Applicable Facility (the "Selected
         Measures"). Licensee acknowledges that the number of Selected Measures
         and the percentage of patients that they represent will need to
         increase each calendar year over the term of the Agreement for JCAHO
         accreditation to be maintained. Accordingly, future additional
         designations of Selected Measures will be made by Licensee as required
         for JCAHO accreditation purposes and will be communicated to Medirisk
         in a timely fashion in a written format reasonably acceptable to
         Medirisk.

         12.2.    SUBMISSION OF DATA TO JCAHO. Licensee hereby designates
         Medirisk as its agent to submit performance measurement data to JCAHO
         on behalf of the Applicable Facilities with respect to the Selected
         Measures. Medirisk will comply with all JCAHO "ORYX" criteria to
         transmit performance measurement data to JCAHO on behalf of the
         Applicable Facilities on a calendar-quarterly basis. Such timely
         submission to JCAHO is dependent upon each Applicable Facility
         submitting its data to Medirisk on a calendar-monthly basis not later
         than the tenth (10th) day of the following month. The initial period
         for which data will be transmitted to JCAHO by Medirisk shall be the
         third quarter of 1998, and such transmission will occur during the
         first quarter of 1999.

         12.3     FEE. [Intentionally Omitted.]

         12.4     CONFIDENTIALITY. Licensee agrees that any restrictions on
         disclosure of patient information by Medirisk set forth in this
         Agreement or otherwise shall not be applicable to submission of the
         subject data to JCAHO by Medirisk.

<PAGE>   10

         12.5     LICENSEE RESPONSIBILITIES AND LIMITATION OF LIABILITY.
         Licensee acknowledges that Licensee's seeking and obtaining JCAHO
         accreditation of the Applicable Facilities is a matter solely between
         Licensee and JCAHO. In such regard Licensee is solely responsible for
         obtaining and supplying clinical performance measurement data directly
         to the JCAHO-approved vendor it selects, with such vendor to then
         transmit such data to JCAHO in accordance with instructions received
         from Licensee. Licensee is solely responsible for informing JCAHO in a
         timely fashion of its selection of both its vendor of choice and the
         clinical performance measures selected. Medirisk is acting only as an
         agent of Licensee in receiving such data directly from Licensee and
         then submitting such data to JCAHO on behalf of, and as selected and
         directed by, Licensee. Absent appropriate instructions from Licensee
         Medirisk will neither submit data to JCAHO nor have any obligation to
         do so. Timely submission of subject data by Medirisk to JCAHO is
         dependent upon each Applicable Facility submitting its complete
         error-free data to Medirisk in a timely fashion and in an appropriate
         format, and Medirisk shall have no liability to Licensee or any other
         party for any delay or failure in submissions to JCAHO resulting from
         an Applicable Facility not supplying its data to Medirisk as and when
         required. Licensee shall indemnify, defend and hold Medirisk harmless
         from any and all liability resulting from Medirisk's submission of data
         to JCAHO as directed by Licensee in accordance with this Agreement,
         including without limitation any and all liability resulting from or
         arising out of any claim that such submission of data violated the
         privacy rights of any patient of Licensee.

13.0     DEFAULT. Either party has the right to terminate this Agreement,
without penalty to the terminating party, if the other party is in default
hereunder as hereinafter set forth. Upon the happening of any default, as
described in provisions (i) through (iv) hereof, the nondefaulting party shall
have all rights and remedies available to it at law and in equity, in addition
to the right to terminate this Agreement under this Section 13.0. In the event
of any termination of this Agreement because of a default by a party hereto,
Licensee shall return the Training Manuals, unused optical scan sheets and all
copies thereof to Medirisk within ten (10) days after receipt of written request
from Medirisk. The respective parties shall be in default under this Agreement
if any of the following occurs:

         (I)      Licensee shall fail to pay when due all or any portion of any
         amount due hereunder, and such amount shall be and remain unpaid for
         ten (10) days following written notice of such nonpayment by Medirisk
         to Licensee;

         (II)     A party shall materially breach or violate any of the other
         terms or conditions of this Agreement and the same shall continue
         thirty (30) days after the other party gives the defaulting party
         written notice thereof; provided, however, that if the defaulting party
         has been unable to cure such default or violation within such thirty
         (30) day period after diligent attempts to do so, such period shall be
         extended while such efforts continue and until such cure is effected.

         (III)    A party shall (i) apply for or consent to the appointment of
         or the taking of possession by a receiver, custodian, trustee or
         liquidator of itself or all of or a substantial part of its property,
         (ii) fail, or admit in writing its failure or inability, or be
         generally unable to pay its debts as such become due, (iii) make a
         general assessment for the benefit of its creditors, (iv) commence a
         voluntary case under the Federal Bankruptcy Code or any similar federal
         or state law, or (v) take any corporate action for the purpose of
         effecting any of the foregoing; or

         (IV)     a proceeding or case shall be commenced, without the
         application or consent of the party hereto that is the respondent in
         such proceeding or case, in any court of competent jurisdiction,
         seeking (i) the liquidation, reorganization, dissolution, winding-up,
         or composition or readjustment of debts of such party, (ii) the
         appointment of a trustee, receiver, custodian, liquidator, or the like
         for such party, of all or any substantial part of its assets, (iii)
         similar relief with respect to such party under any law relating to
         bankruptcy, insolvency, reorganization, winding-up or composition and

         matter hereof. This Agreement shall not be modified or amended without

         this Agreement and the Statement of Work, the terms of the Statement of
         Work shall control.

         14.2     WAIVER. No waiver of any breach of any provision of this
         Agreement shall constitute a waiver of any prior, concurrent or
         subsequent breach of the same or any other provision hereof and no

         provisions of this Agreement shall be held invalid or otherwise

         sent. Each notice, demand, request or communication which shall be
         mailed, delivered, or transmitted in the manner described above shall
         be deemed sufficiently given, served, sent and received for all
         purposes at such time as it is delivered to the addressee (with the
         return receipt, the delivery receipt, the affidavit of messenger or the
         answer back (or, with respect to a facsimile transmission, the report
         generated by the transmitting facsimile machine confirming successful
         transmission of the facsimile) being deemed conclusive evidence of such
         delivery) or at such time as delivery is refused by the addressee upon
         presentation.

         14.4     FORCE MAJEURE. If either party is unable to perform any of its
         obligations hereunder, or is unable to enjoy a benefit hereunder
         (including without limitation loss of or failure to provide the
         product(s) and/or service(s)), due to any event beyond the reasonable
         control of such party, including without limitation weather and all
         other Acts of God, war, fire, heat, cold, explosion, flood, power or
         telephone failures, acts or omissions of any government or agency
         thereof, compliance with requirements, rules, regulations or orders of
         any governmental authority or instrumentality thereof, labor
         difficulty, supplier failure or delay, civil disorder, or breakdown or
         malfunction of machinery, transportation facilities or other equipment
         of any nature, then such party's performance shall be excused for the
         pendency of such event, but such party shall in good faith use its best
         efforts to limit the duration of any such delay.

         14.5     GOVERNING LAW. This Agreement is entered into in, and shall be
         governed by and construed under, the laws of the State of Georgia.

         14.6     ATTORNEYS' FEES. If any sums due and owing under this
         Agreement are collected by or with the assistance of legal counsel, or
         if a party brings suit of any type against the other party and prevails
         in such action, then the losing party shall be liable to the prevailing
         party, and shall promptly remit to the prevailing party upon demand,
         all of the prevailing party's costs and expenses incurred with respect
         thereto, including without limitation court costs and reasonable
         attorneys' fees.

         14.7     INDEPENDENT CONTRACTOR. The relationship between the parties
         established in this Agreement shall be solely that of independent
         contractors and does not designate either party as the agent, legal
         representative, partner or joint venturer of the other party for any
         purpose whatsoever. Neither party is granted any right to create any
         obligation or responsibility or make representations, express or
         implied, on behalf of or in the name of the other party or to bind the
         other party in any matter or thing whatsoever.

DISCLAIMER: LICENSEE ACKNOWLEDGES THAT THE FOLLOWING SAMPLE RELEASE LANGUAGE IS
PROVIDED BY MEDIRISK MERELY AS A COURTESY TO LICENSEE AND THAT MEDIRISK
DISCLAIMS ANY REPRESENTATION OR WARRANTY AS TO THE EFFECTIVENESS OR SUFFICIENCY
OF THIS PARTICULAR LANGUAGE. LICENSEE IS ADVISED TO CONSULT ITS OWN LEGAL
COUNSEL TO DETERMINE HOW TO SATISFY ITS RELEASE OBLIGATIONS UNDER THE FOREGOING
AGREEMENT. LICENSEE ACKNOWLEDGES AND AGREES THAT THE DECISION TO USE AND INCLUDE
ANY RELEASE LANGUAGE IN ANY DOCUMENT PROVIDED BY LICENSEE TO ITS PATIENTS SHALL
BE SOLELY UNDER THE CONTROL OF LICENSEE AFTER IT HAS OBTAINED REVIEW AND
APPROVAL OF SUCH LANGUAGE AND THE FORM OF ANY RELEASE DOCUMENT FROM ITS LEGAL
COUNSEL. THE FORM OF RELEASE SELECTED BY LICENSEE SHALL NOT BE SUBJECT TO REVIEW
OR APPROVAL BY MEDIRISK. LICENSEE FURTHER ACKNOWLEDGES THAT THE SAMPLE LANGUAGE
SET FORTH BELOW IS INTENDED TO ADDRESS ONLY THE INFORMED CONSENT ISSUES
CONCERNING DISCLOSURE TO, AND THE OBTAINING OF FACILITY AND PATIENT INFORMATION
BY, MEDIRISK UNDER THIS AGREEMENT, AND IS NOT INTENDED AS AN EXCLUSIVE CONSENT

TO, ANY PARTICULAR PATIENT.


                                Sample Provision:

"RELEASE OF INFORMATION TO THIRD-PARTY CONTRACTORS OF [HOSPITAL]; POST-DISCHARGE
FOLLOW-UP CONTACTS. [Patient] hereby authorizes [Hospital] to disclose, orally
and/or in writing, any and all personal information concerning [Patient] which
[Hospital] has or may obtain (including without limitation [Patient]'s name,
address, sex, reason for admission, general nature of injuries, general
condition, diagnosis, symptoms, treatment plans, outpatient tests,
consultations, demographic and functional status) to any third-party contractor
(or agent thereof) of [Hospital] which [Hospital] has contracted to provide
statistical or similar analysis of any type with respect to [Patient] and/or
[Hospital] or any facility(ies) thereof. [Patient] further acknowledges that at
some point after [Patient]'s discharge from [Hospital], such contractor or an
agent thereof may contact [Patient] by telephone or otherwise for purposes of
one or more post-discharge surveys concerning [Patient]'s then-current physical
condition and recovery status, and [Patient] hereby authorizes and consents to
such contact(s) and agrees, on behalf of [Patient] and his or her
representatives, to use his or her best efforts to cooperate in providing any
requested information to such contractor's representative. [Patient] also hereby
acknowledges that any data which it submits to the contractor, or which the
contractor otherwise obtains from or on behalf of [Hospital] concerning
[Patient], may be entered into any general database of the contractor, at said
contractor's discretion, and that said contractor may use and/or otherwise
provide data to third parties from such database, at said contractor's
discretion, so long as said contractor only discloses such data to third parties
in a fashion that does not expressly reveal the identity of [Patient]; provided,
however, that said contractor may reveal the identity of [Patient] to research
organizations or consultants subject to pertinent confidentiality restrictions
to which the contractor and such other parties are bound. [Patient] acknowledges
that such research organizations will generally be prohibited from further
disclosing the identity of [Patient], subject to exceptions permitting further
limited disclosure as may be permitted by the contractor in the exercise of its
reasonable discretion."

                                 ATTACHMENT "A"

                MEDIRISK-HEALTHSOUTH 1998-2000 STATEMENT OF WORK

         Medirisk of Illinois, Inc. ("Medirisk") will perform the
Outcomes-related data analysis and reporting functions for HEALTHSOUTH
Corporation ("HEALTHSOUTH") as established below during the term of the new
agreement. All such work will be performed utilizing instruments that comprise a
part of the Medirisk FORMATIONS(SM) Clinical Outcomes System and will encompass
the following service areas: Inpatient Products, Hospital-Based Outpatient
Products and Joint Commission on Accreditation of Healthcare Organizations
("JCAHO") compliance. The work to be performed for each of such service areas
will be as follows:

1.       INPATIENT PRODUCTS

         A.       Instruments

         The FORMATIONS(SM) Medical Outcomes System Version 2.0 measurement
tools will be used, including a descriptor dataset, a comorbid disease dataset,
and a rehabilitation dataset (which includes functional independence measures,
Rancho Los Amigos Coma Scale and Instrumental Activities of Daily Living
("IADL")). Additional datasets will be used as needed by each facility and will
include pain, wound, respiratory, and nutrition instruments.

         Medirisk will receive data from facilities on disk via HCIS. Data on
all patients will be submitted on a monthly basis. HEALTHSOUTH will provide such
data to Medirisk no later than the tenth (10th) day of the month following the
reporting month in question. HEALTHSOUTH will provide HCIS programming.

         B.       Number of Locations/ Volume:

         HEALTHSOUTH currently owns and operates 104 rehabilitation hospitals,
12 of which maintain separate subacute/skilled care unit/facilities. Currently
70 of these hospitals participate in the Medirisk outcomes program. During 1998
thirty-four (34) additional rehabilitation hospitals will be added (including 30
recently acquired CMS facilities). This will occur on or around April 1, 1998.
Facilities that are managed by HealthSouth, but not owned by HEALTHSOUTH, will
be free to contract with Medirisk independently and will not be covered under
the new master agreement.

         Data on all inpatient admissions will be reported by HEALTHSOUTH to
Medirisk. Medirisk will report back to HEALTHSOUTH on all patients who can be
classified into one or more of the following impairment groups: stroke,
orthopedic, head injury, spinal cord, debility, or "others not classified". This
number is expected to be approximately [*] discharges in 1998.

         Aggregate reports will be prepared for all patients for which data and
a patient ID number is submitted along with a valid impairment code falling
within the impairment codes of stroke, orthopedic, head injury, spinal cord,
debility, and "others not classified". Medirisk will make substantial efforts to
insure that data received is complete and properly transmitted.

         C.       Facility Reports

         Each of the facilities will receive a quarterly Facility Report. These
reports will be shipped to each respective facility by the fifteenth (15)
calendar day of the second month following the end of the reporting quarter. The
Facility Report for the fourth quarter of each calendar year will be modified to
replace the current year-end report provided to HEALTHSOUTH facilities. This
report will be a cumulative report for the entire year and will be shipped to
each respective facility by February 15th of each calendar year.

         Facilities will receive one bound black and white copy and one unbound
copy containing color graphs for each of the quarterly reports and the year end
report.


* Confidential treatment requested

<PAGE>   22

         Reports for facilities added to the Medirisk outcomes system during
1998 will be prepared and distributed by July 15, 1998, and will include
discharges for the first quarter of 1998. Thereafter these facilities will
follow the same distribution schedule as for other facilities.

         D.       Corporate Reports

         HEALTHSOUTH corporate office will receive 4 copies of a quarterly
report which summarizes in aggregate form the data for all reported facilities
for such quarter. These reports will be shipped to the Quality Standards
department by the fifteenth (15) calendar day of the second month following the
end of the reporting quarter in question. The Corporate Report for the fourth
quarter of each calendar year will be modified to replace the current Corporate
year-end report provided to HEALTHSOUTH corporate. This report will be a
cumulative report for the entire year and will be shipped to each respective
facility by February 15th of each calendar year. These reports will also be
provided to HEALTHSOUTH corporate in electronic format in a format mutually
agreed to by both parties.

         Medirisk will also continue to provide to HEALTHSOUTH corporate a
quarterly Corporate Trend Report that reflects only functional independence
measure data. This report will continue to represent all diagnostic and
impairment groups consistent with previously supplied reports in order to
provide consistent data over time. These reports will be shipped to the Quality
Standards department by the fifteenth (15) calendar day of the second month
following the end of the reporting quarter in question. This report will also be
provided to HEALTHSOUTH corporate in electronic format in a format mutually
agreed to by both parties.

         Medirisk will continue to provide a quarterly Corporate Ranking Report
which will be redesigned by the end of the first quarter of 1998 to incorporate
a more equitable ranking methodology. The format of this report will be proposed
by Medirisk and mutually agreed upon by Medirisk and HEALTHSOUTH. This report
will also be provided to HEALTHSOUTH corporate in electronic format in a format
mutually agreed to by both parties.

         All corporate reports, including the previously mentioned Corporate
Trend Reports, will include data on the following impairment groups: stroke,
orthopedic, head injury, spinal cord, debility, and "others not classified",
though data from other impairment groups will have been sent to Medirisk.

         E.       Follow-Up Phone Interviews

         Medirisk will perform follow-up phone interviews within a window of 80
to 100 days from the date of patient discharge on a representative sample of
patients discharged from a HEALTHSOUTH facility in one of the following
impairment groups: stroke, orthopedic, head injury, spinal cord, and debility.
Medirisk will complete interviews with [*] per cent ([*]%) of patients from
the following impairment groups: stroke, orthopedic, head injury, spinal cord,
and debility, which is expected to result in the completion of approximately
[*] calls completed within each calendar year. Patients interviewed will come
from the subset of patients who have clean data submitted. In no case is the
number of patients to be interviewed to exceed [*] per calendar year without
the express written consent of HEALTHSOUTH Corporation.

         F.       Follow-Up Reports

         With respect to the follow-up phone interviews Medirisk will provide
the following reports for each facility on a quarterly basis: an aggregate
follow-up report, a patient comments report, and a call completion report. A
monthly status report will also be provided to each facility by the 10th
calendar day of the end of each month. A "Red Flag" notification will be
immediately communicated to the affected facility in the event that former
facility patients indicate that they are experiencing an emergency situation.
Medirisk will provide to HEALTHSOUTH corporate a quarterly call completion
report that lists basic summary information concerning call completion such as
number of calls completed per facility, the number of calls per impairment
group, and any other additional useful information mutually agreed upon by
Medirisk and HEALTHSOUTH. Medirisk will develop and provide to HEALTHSOUTH
Corporate a trend report displaying the percentage of patients who have
maintained their functional gains.

         G.       Training

         Two videos will be recorded for the purpose of training HEALTHSOUTH
staff on the use of the FORMATIONS Medical Outcomes System Version 2 measurement
tools. HEALTHSOUTH will assume responsibility for payment for the production of
the videos. Medirisk will provide the staff to write the script for the videos
and will provide a trainer to narrate these videos.

         The current functional independence measure /IADL video will be updated
by the close of business, December 31, 1997, to reflect the changes in the IADL
instrument contained within Medical Outcomes System Version 2. HEALTHSOUTH will
mail copies of the video to its facilities for the purposes of verification and
training in the functional independence measure/IADL instruments for new
facilities simultaneously for all facilities by April 1, 1998. By April 1, 1998,
a new video, which will include training on the pain, wound, respiratory, and
nutrition instruments will also be developed by Medirisk and mailed by
HEALTHSOUTH to all facilities who choose to use these optional instruments.
HEALTHSOUTH will send videos trainings, on an as-needed basis, to assure that
new staff are properly certified. Medirisk will provide all existing HEALTHSOUTH
facilities with updated training manuals.

         All HEALTHSOUTH clinicians currently certified in the FORMATIONS
Medical Outcomes System Version 1 rehabilitation instruments will be required to
update their certification by viewing the new video(s) and by signing a form to
indicate their understanding of the changes. This shall be completed by end of
business on March 31, 1998. This signed form will be returned to Medirisk who
will assign a new certification ID number to each clinician. This will serve to
update current certification status.

         Training manuals will be made available by Medirisk to each clinician
prior to viewing the training videos and taking the certification test for the
FORMATIONS Medical Outcomes System Version 2 rehabilitation instrument.
Clinicians will only receive training and testing for those instruments
pertinent to the performance of their job duties, selection of which will be the
responsibility of HEALTHSOUTH. Upon successful completion of the test each
clinician will receive a certificate from Medirisk.

         Each certified clinician shall be entered into the Medirisk Rater
Database. Upon receipt and processing of patient data the processing program
provided by Medirisk shall determine whether or not the data contains an ID
number representing a certified clinician. Data containing ratings from
non-certified clinicians will not be processed, however, data containing
multiple ratings from both certified clinicians and non-certified clinicians
will be included in the report. Medirisk will produce a list of non-certified
clinicians for HEALTHSOUTH by the end of the third quarter of 1998 and return
such information to each affected facility along with training manuals and
certification tests sufficient to certify any and all non-certified clinicians.
Medirisk representatives will work with clinicians to obtain proper
certification.

         Medirisk will provide one "Guide for Interpreting Your Report" for each
HEALTHSOUTH facility no later than April 30, 1998, to accompany the first
FORMATIONS Medical Outcomes System Version 2 report.

         The final agreed-upon pricing will include the provision of up to a
maximum of 15,000 "Training Manuals", 15,000 certificates, and 104 "Guides to
Interpreting Your Report" over the three year contract period, provided however
that such amount may be re-negotiated upward upon the mutual consent of both
parties to this agreement.

         H.       Process Analysis

         Medirisk will not perform a process analysis prior to implementation of
FORMATIONS Medical Outcomes System Version 2.0.

         I.       Roll Out Activities

         Medirisk will provide a detailed implementation package for each of the
thirty-four (34) new HEALTHSOUTH rehabilitation hospitals to be added during
1998. This package, in loose-leaf notebook form will include, at a minimum: an
overview of Medirisk and Medirisk products, copies of new sample reports,
schedules for data collection and data reporting, and sufficient training
information. A copy will also be provided to all existing facilities. Medirisk
will make at minimum two calls to each new HEALTHSOUTH rehabilitation hospital:

once to verify receipt of the loose-leaf notebook materials; once to answer
questions that facility representatives may have after they have viewed the
training video.

         J.       Other Items

         Medirisk will meet with HEALTHSOUTH (either at corporate headquarters
in Birmingham, Alabama and/or at one or more facilities to be designated by
HEALTHSOUTH) on an as-needed basis a maximum of 4 times per year at no
additional fee to HEALTHSOUTH. Visits not utilized on behalf of inpatient
rehabilitation hospitals will not expire; rather they will accrue to the benefit
of other HEALTHSOUTH divisions as needed to a maximum of the total number of
visits provided for with the contract.

<PAGE>   25


2.       HOSPITAL-BASED OUTPATIENT PRODUCTS

         A.       Instruments

         Medirisk will design a custom General Rehabilitation instrument to be
used exclusively by HEALTHSOUTH outpatient clinics that includes the Formations
Descriptor Dataset and a custom rehabilitation dataset incorporating all of the
items from the current functional independence measure and IADL instruments. For
functional independence measure items a new field of "not applicable" will be
added to each instrument. A custom patient survey focusing on high level
mobility skills will also be designed by Medirisk. The patient survey will be
completed by patients who are capable of completing it independently or
otherwise completed by clinicians at the beginning and end of each patient's
treatment.

         This custom General Rehabilitation instrument will be available for
HEALTHSOUTH outpatient clinics on or before April 1, 1998.

         Medirisk will custom design the patient questionnaire portion of these
instruments for the exclusive use of HEALTHSOUTH and will not make it available
in its entirety for use by any other Medirisk clients. Thus comprehensive
instrument benchmarking outside of HEALTHSOUTH will not be available except for
variables used in common with the Medirisk tool.

         Medirisk reserves the right to make modification to the instrument
after the first quarter of data is received and analyzed.

         All data collection will be done on HCIS, with all programming provided
by HEALTHSOUTH

         Data collection will begin no later than April 1, 1998. Data on all
patients will be collected by HEALTHSOUTH and submitted to Medirisk not later
than the 10th calendar day of the month following the reporting month in
question.

         B.       Number of Locations/Volume

         HEALTHSOUTH owns and operates ninety-nine (99) rehabilitation
hospital-based outpatient clinics with a total volume of approximately [*]
patients annually. Data collection for this group of clinics will begin on April
1, 1998.

         Data on all patients will be reported to and collected by Medirisk.
Medirisk will prepare reports on those patients belonging to the following
impairment groups: stroke, spinal cord injury, orthopedic, head injury, debility
and "others not classified". This number is expected to be approximately [*]% of
the total volume, approximately [*] patients.

         C.       Clinic Reports

         The patient questionnaire portion of the Clinic Report will be
customized for HEALTHSOUTH and no other Medirisk client will receive this
report. The custom report will include, at a minimum, the following items: an
executive summary, tables, and graphs.

         Each of these 99 rehabilitation hospital-based outpatient clinics will
receive a quarterly Clinic Report. The deadlines for the production of these
reports will begin at the end of the second quarter of 1998. These reports will
be shipped to each respective facility by the fifteenth (15) calendar day of the
second month following the end of the reporting quarter in question. The
Facility Report for the fourth quarter of each calendar year will be a
cumulative report for the entire year and will be shipped to each respective
facility by February 15th of each calendar year. These reports will also be
provided to HEALTHSOUTH corporate in electronic format in a format mutually
agreed to by both parties.

         Clinics will receive one bound black and white copy and one unbound
copy containing color graphs for each of the quarterly reports and the year end
report.

         Aggregate reports will be prepared for all patients for which data and
a patient ID number is submitted along with a valid impairment code falling
within the impairment codes of stroke, orthopedic, spinal cord injury, head
injury, debility, and "others not classified". Patients will be counted for
billing purposes by Medirisk whether

<PAGE>   26

or not the data that is sent is complete. Medirisk will make substantial efforts
to insure that data received is complete and properly transmitted.

         D.       Corporate Reports

         Medirisk will publish a HEALTHSOUTH General Rehabilitation Corporate
Report which will be shipped to HEALTHSOUTH corporate by the fifteenth (15)
calendar day of the second month following the end of the reporting quarter in
question. The initial report will be for the second quarter of 1998. The
Corporate Report for the fourth quarter of each calendar year will be a
cumulative report for the entire year and will be shipped to HEALTHSOUTH
corporate by February 15th of each calendar year. The patient questionnaire
portion of the report will have not external benchmarks.

         Medirisk will also publish a quarterly Corporate Ranking Report which
will be shipped to HEALTHSOUTH corporate by the fifteenth (15) calendar day of
the second month following the end of the reporting quarter in question. The
initial report will be for the second quarter of 1998.

         These corporate reports will contain information for patients falling
within the impairment codes of stroke, orthopedic, spinal cord injury, head
injury, debility, and "others not classified".

         E.       Training

         A satellite video telecast will be broadcast for the purpose of
training HEALTHSOUTH staff on the use of the HEALTHSOUTH General Rehabilitation
Instrument. HEALTHSOUTH will assume responsibility for payment for the
production of the telecast and the broadcasts of these satellite training.
Medirisk will provide the staff to write the script for the telecast and will
provide a trainer to narrate the telecast. For those HEALTHSOUTH facilities
without satellite receiving capabilities a video tape copy of the satellite
broadcast will be made available to them by HEALTHSOUTH corporate. HEALTHSOUTH
will continue to broadcast trainings, on an as-needed basis, to assure that new
staff are properly certified. The initial broadcast will take place in March
1998.

          Training manuals and certification tests will be made available by
Medirisk to each clinician prior to viewing the training videos. Upon successful
completion of the test each clinician will receive a certificate from Medirisk.

         Each certified clinician shall be entered into the Medirisk Rater
Database. Upon receipt and processing of patient data the processing program
provided by Medirisk shall determine whether or not the data contains an ID
number representing a certified clinician. Data containing ratings from
non-certified clinicians will not be processed, however, data containing
multiple ratings from both certified clinicians and non-certified clinicians
will be included in the report. Medirisk will produce a list of non-certified
clinicians for HEALTHSOUTH by the end of the third quarter of 1998 and return
such information to each affected clinic along with training manuals and
certification tests sufficient to certify any and all non-certified clinicians.
Medirisk representatives will work with clinicians to obtain proper
certification.

         Medirisk will provide one "Guide for Interpreting Your Report" for each
HEALTHSOUTH clinic no later than July 31, 1998, to accompany the first report.

         The final agreed-upon pricing will include the provision of up to a
maximum of 204 "Training Manuals", 510 tests, 510 certificates, and 99 "Guides
to Interpreting Your Report" over the three year contract period, provided
however that such amount may be re-negotiated upward upon the mutual consent of
both parties to this agreement.

         F.       Process Analysis

         Medirisk will perform a Process Analysis for HEALTHSOUTH which will
include feedback from HEALTHSOUTH staff who are using the instruments, and
summarization of the findings. As part of the process analysis a Medirisk
representative will visit three (3) HEALTHSOUTH hospital-based outpatient
clinics, the location and time of which will be determined jointly upon
consultation with representative of HEALTHSOUTH. Visits not utilized on behalf
of inpatient rehabilitation hospitals outpatient clinics will not expire; rather
they will accrue to the benefit of other HEALTHSOUTH divisions as needed to a
maximum of the total number of visits provided for with the contract.

3.       JCAHO COMPLIANCE

         Medirisk will send performance measure data to JCAHO on behalf of
HEALTHSOUTH's impatient rehabilitation facilities in order that HEALTHSOUTH may
comply with JCAHO's "ORYX" criteria. Medirisk will comply with any and all
deadlines established by JCAHO. Medirisk will also seek to apprise HEALTHSOUTH
of any information received from or pertaining to JCAHO which Medirisk
reasonably determines should be provided to HEALTHSOUTH.

         Upon request, Medirisk will assist each facility in the selection of an
appropriate compliance measure for each year of the new agreement. These may
come from the list of approved measures supplied by Medirisk or the HEALTHSOUTH
patient satisfaction vendor, National Research Corporation. Both the number of
measures supplied and the percent of patients they represent may increase over
the term of this agreement.

         Medirisk will compile monthly data points for each of HEALTHSOUTH's
accredited programs that choose to use Medirisk's outcomes measures and transmit
this data to JCAHO on a quarterly basis, subject to all requirements established
by JCAHO for compliance. Medirisk further agrees to hold HEALTHSOUTH harmless in
the event of non-compliance with JCAHO requirements that results from the
non-performance of Medirisk with the requirements of this agreement.

         Data submissions are expected to begin in the first quarter of 1999 and
will represent the third quarter of 1998, subject to requirements established by
JCAHO.

         It is anticipated that JCAHO will charge a set fee for each measure
that is transmitted by Medirisk to JCAHO on behalf of HEALTHSOUTH. For the
purposes of pricing Medirisk assumes that each of HEALTHSOUTH's inpatient
rehabilitation hospitals will select one measure and will charge accordingly up
to a limit of 137 measures.

         Medirisk will send each participating HEALTHSOUTH -accredited program a
JCAHO report at a minimum five business days prior to transmittal of the report
to JCAHO.

         Medirisk agrees to keep performance measures up to date. At the time of
submission of this proposal of Statement of Work, Medirisk has obtained approval
from JCAHO for a total of eighty-seven (87) measures. During the term of this
agreement Medirisk, on behalf of HEALTHSOUTH, agrees to submit to JCAHO for
approval a total of up to [*] new measures annually.

         No corporate reporting of JCAHO reports is anticipated.

         Medirisk will implement this process and procedure for HEALTHSOUTH
inpatient rehabilitation hospitals during 1998. A separate quote will be
provided for additional reports or other programs covered under new JCAHO
regulations on an as-needed basis.

*Confidential treatment requested

5.       GENERAL

         All of the foregoing anticipated report shipping dates assume the
timely provision of data to Medirisk by HEALTHSOUTH and are not guaranteed in
the event of delay in timely receipt of complete and accurate data by Medirisk,
provided that such delay are found to be caused by HEALTHSOUTH and not by
Medirisk.

         After January 1, 1998, any substantial modifications required to be
made to Medirisk products at the specific request of HEALTHSOUTH will be paid
for by HEALTHSOUTH subject to the approval of a cost estimate for such change by
HEALTHSOUTH and prior to the implementation of such changes. Medirisk will only
market such revised products to others with the expressed written consent of
HEALTHSOUTH. Medirisk will include preferential hourly labor rates in the
preparation of such cost estimates.

         Freestanding orthopedic outpatient clinics are not included in this
Statement of Work and will be negotiated in a separate contract if so desired.
