                                      PART I

Item 1.  Business

General

  OccuSystems is the nation's largest physician practice management company
focusing on occupational healthcare. The Company currently manages the practices
of 201 physicians in the Company's 115 occupational healthcare centers located
in 31 markets in 16 states. OccuSystems provides the management, facilities,
administrative and technical support, case management, physical therapy services
and other ancillary services necessary to establish and maintain a fully
integrated network of occupational healthcare providers. The Company believes
that this network of physicians and facilities combined with the Company's
management expertise and cost containment programs provide significant
advantages to patients, employers, physicians and payors in reducing the overall
costs associated with occupational healthcare. Since December 1, 1991, the
Company has acquired the assets of 110 physician practices and developed 25
physician practices.


Industry Overview

  The market to provide occupational healthcare services is highly fragmented.
Occupational medical care is largely provided by independent physicians, who
have experienced increasing pressures in recent years from cost containment
efforts, growing regulatory complexity, medical liability concerns and increased
competition. Although risk sharing programs have yet to become a major factor in
occupational healthcare, the Company anticipates that such programs, including
capitation plans (i.e., plans that charge fees on a per capita basis, regardless
of services provided) and case rate plans (i.e., plans that charge fees on a per
diagnosis basis), may play an increasing role in the delivery of occupational
healthcare services. In addition, the Company anticipates that competition in
the occupational healthcare industry may shift from individual practitioners to
specialized provider groups, such as those managed by the Company, insurance
companies, health maintenance organizations (''HMOs'') and other significant
providers of managed care products.

  Occupational healthcare consists of two primary components: (i) workers'
compensation injury care and related services; and (ii) non-injury healthcare
services related to employer needs or statutory requirements.


  Workers' Compensation

  Due to several factors, including an increase in the number of work-related
injuries and illnesses, a general rise in the cost of occupational healthcare,
and the requirement that employers pay the majority of lost wages and all
compensable medical and non-medical costs of their employees, the dollar amount
of workers' compensation claims has increased significantly in recent years,
resulting in escalating costs to employers. The Company anticipates that
employers' direct costs of workers' compensation will continue to escalate
primarily because of broader definitions of work-related injuries and illnesses
covered by workers' compensation laws, the shifting of medical costs from group
health plans to the workers' compensation system, an aging work force and, most
importantly, the absence of comprehensive cost containment programs (such as
those that encourage early return-to-work and limited duty) that are necessary
to reduce the non-medical costs associated with workers' compensation. As
workers' compensation costs escalate, the Company expects that employers will
continue to seek and implement strategies and programs to reduce workers'
compensation costs and to improve worker productivity, health and safety.

  Each state has adopted its own workers' compensation benefit system to
compensate individuals who are injured or who contract illnesses while
performing their job duties. In addition, federal statutes provide a workers'
compensation benefit system for federal employees. These systems generally
require employers to pay a significant portion of lost wages and all of an
employee's costs of medical treatment, legal fees and other associated costs,
with no co-payment or deductible due from the injured or ill worker. In
addition, there is typically no lifetime maximum or limit on expenses, and the
injured worker has no financial responsibility for those expenses. In exchange
for providing this coverage for employees, employers are not subject to
litigation by employees for benefits in excess of those provided by the relevant
state statute. The extensive benefits coverage (for both lost wages and medical
costs) is provided through the purchase of commercial insurance from private
insurance companies, participation in state-run insurance funds or employer
self-insurance. In two states (Texas and New Jersey), employers are permitted to
refrain from 

                                       2
<PAGE>
 
purchasing or procuring any such insurance coverage, thereby exposing themselves
to significant potential liability as the result of an employee's work-related
injury or death. Such employers are sometimes termed ''non-subscribers''.

  Reimbursement to healthcare providers is determined by a number of different
methods in states where employers obtain workers' compensation insurance
coverage. As of December 31, 1996, 40 states had adopted fee schedules pursuant
to which all healthcare providers are uniformly reimbursed. These fee schedules
are set by each state and generally prescribe the maximum amounts that may be
reimbursed for a designated procedure. In states without fee schedules,
healthcare providers are reimbursed based on usual and customary fees charged in
the particular market for the services provided.  Of the 16 states in which the
Company operates, twelve have fee schedules.

  Limitations on an employee's right to choose a specific healthcare provider is
dependent upon the particular state statute. According to the Workers'
Compensation Research Institute, as of December 31, 1996, 24 states limited the
employee's choice of provider and 36 states placed restrictions on switching
providers, including provisions requiring employer approval for any changes.
Generally, the employer will also have the ability to direct the employee when
the employer is self-insured or a non-subscriber. The Company believes that
employers greatly influence their employees' choices of physicians even in
states in which the employees may select their providers. As a result, it has
been the Company's experience that its results of operations and prospects in a
particular state are not materially dependent upon state statutes regarding
direction of employees.


  Non-Injury Healthcare Services

  Non-injury healthcare services provided by the Company include employment-
related physical examinations, drug and alcohol testing, functional capacity
testing and other related programs designed to meet specific employer needs.
Non-injury healthcare services also include programs to assist employers in
complying with a continuously expanding list of federal and state governmental
requirements, including hearing conservation programs, toxic chemical exposure
surveillance and monitoring programs, and Department of Transportation and
Federal Aviation Administration physical examinations. Federal laws governing
health issues in the workplace, including the Americans with Disabilities Act
(the ''ADA''), have increased employers' demand for healthcare professionals who
are experts in the delivery of these regulated services.


Strategy

  The Company's objective is to organize primary care physicians who specialize
in occupational medicine within regional networks of occupational healthcare
centers that provide cost-effective healthcare services to individuals injured
in the workplace, perform various employment-related testing services and assist
employers in complying with the occupational regulations and requirements of
various government agencies. The Company believes that if an injured worker is
given access to a well-organized, vertically integrated delivery system, and if
the entire injury resolution process is administered and managed properly,
maximum cost savings to the employer will be realized. The Company believes that
it can generate the greatest savings for employers and other payors by reducing
non-medical costs, such as lost time wages, disability payments and
administrative costs, which are variable in nature and represent approximately
60% of all costs associated with workers' compensation.

      The Company's strategy is as follows:

     Continue to Consolidate Primary Care Physician Practices Specializing in
  Occupational Medicine.   The Company estimates that there are more than 2,000
  healthcare centers in the United States in which physicians who specialize in
  occupational medicine are providing occupational healthcare services. The
  Company believes that, due to increasing business and regulatory complexity,
  capital requirements and the development of larger integrated networks such as
  the Company's, an increasing number of physicians are seeking to affiliate
  with larger, professionally managed organizations. OccuSystems has established
  affiliations with 201 physicians and intends to move aggressively to establish
  additional affiliations.

     Develop Clusters of Occupational Healthcare Centers.   OccuSystems
  organizes its centers in each market into clusters to serve employers, payors
  and workers more effectively, to leverage management and other resources and
  to facilitate the development of integrated networks of affiliated physicians
  and other healthcare providers. The Company has established operations in 31
  markets, has acquired the assets of 110 physician practices and has developed
  25 physician practices. The Company has also entered into three joint venture
  agreements through which it operates seven centers. The Company intends to
  develop additional centers in new markets and within existing markets
  primarily through acquisitions and joint ventures. The 

                                       3
<PAGE>
 
  Company is in discussions with numerous potential acquisition and joint
  venture candidates and is planning the development of several other centers.

     Develop and Affiliate with Vertically Integrated Networks of Providers.
  The Company is positioning its centers to operate successfully within emerging
  models of healthcare payment and delivery by actively developing and
  affiliating with vertically integrated networks of specialists, hospitals and
  other healthcare providers. These networks are designed to provide quality
  care to patients at substantially reduced costs. With these networks, the
  Company believes that it can cost-effectively develop risk sharing programs,
  such as case rate and capitation products, covering the full range of costs
  associated with work-related injury and illness care.

     Employ Its Information Systems and Its Regulatory and Practice Management
  Expertise to Optimize the Performance of Its Centers and Enhance Its
  Affiliated Physicians' Practices.   The Company's extensive proprietary
  knowledge base and information systems relating to workplace injuries,
  treatment protocols, outcomes data and the workers' compensation system
  enhance the Company's ability to furnish high-quality, efficient healthcare
  services while complying with the complexity of regulations governing the
  occupational healthcare system. Furthermore, it is the Company's strategy to
  use its knowledge base and information systems to continue to expand its non-
  injury care services. The Company's expertise also allows it to efficiently
  run all business aspects of center operations, including billing and
  collection, accounting, tax and financial management, marketing and human
  resource management, enabling its affiliated physicians to focus on the
  practice of medicine.

     Implement Its Proprietary Active Injury/Illness Management Program.   The
  Company's cost-containment programs are designed to manage the injury and
  illness resolution process to accelerate the employee's return to work in an
  appropriate manner while ensuring quality care. As part of this outcome-
  oriented approach, the Company provides proactive case management services
  through its proprietary ''AIM(SM)'' (Active Injury/Illness Management)
  program. AIM(SM) enables the Company to assist physicians in managing the
  entire injury resolution process--from the moment of initial treatment to
  return to work--to focus on eliminating costly inefficiencies without
  compromising quality of care. See ''Operations--Active Injury/Illness
  Management.''

     Market Its Services on a Case Rate and Capitated Basis.   Utilizing its
  proprietary information systems, the Company has developed an extensive data
  base of clinical outcomes, established case rates by diagnosis and conducted
  the risk analysis necessary to create and offer services on a case rate and
  capitated basis. The Company is expanding its marketing of such services to
  employers, insurers and managed care organizations and is working with
  insurers and other payors to develop other innovative reimbursement programs.


Operations

   Agreements With Physician Groups

  Due to increasing financial, administrative, regulatory and legal burdens
associated with the practice of medicine in the emerging managed care
environment, many physicians are seeking alternative practice models such as
large group practices. The Company seeks to provide the necessary business
support services to enable physicians to focus on the medical rather than the
business aspects of their practices. The Company provides a wide array of
business services with which the Company is affiliated (the ''Physician
Groups''), such as providing nurses and other medical support personnel,
practice and facilities management, billing and collection, accounting, tax and
financial management, human resource management, risk management, marketing and
information-based services such as process management and outcomes analysis. As
another service to the Physician Groups, the Company recruits physicians,
nurses, physical therapists and other healthcare providers.
   
  Physician and physical therapy services are provided at the Company's centers
under management agreements with the Physician Groups, which are independently
organized professional corporations that hire licensed physicians and physical
therapists to provide medical services to the centers' patients. The management
agreements between the Company and the Physician Groups with respect to the 201
affiliated physicians have 40-year terms. Pursuant to each management agreement,
receivables are collected by the Company on behalf of the Physician Groups. The
Company advances funds for payment of each Physician Group's expenses, including
salaries, shortly after services are rendered to patients. Under the terms of
each management agreement, the Company provides each Physician Group with most
non-physician support and all facilities, supplies and marketing services
necessary for the Physician Group to render services to the centers' patients.
For those services, the Company receives a management fee based on the net 
revenues attributable to the services provided by the medical staff. Deductions 
from such revenues include compensation and benefits costs related to the 
providers, malpractice insurance premiums, and other miscellaneous expenses 
associated with these employees. The balance remaining after the aforementioned 
deductions represents the management fee. The management fee is subject to
renegotiation and may be adjusted from time to time to reflect industry
practice, business conditions and actual expenses for administrative     

                                       4
<PAGE>
 
discounts and bad debts. The Company provides services to the Physician Groups
as an independent contractor and is responsible only for the non-medical aspects
of the Physician Groups' practices. The Physician Groups retain sole
responsibility for all medical decisions.

  The management agreements between the Company and the Physician Groups are
terminable by either party only for cause. Although the Company believes that,
in the event any such agreement were terminated, it could enter into agreements
with other physicians on terms as favorable as its current management
agreements, there can be no assurance that disruption to its business would not
occur.

  Individual physicians who perform services pursuant to contracts with a
Physician Group are employees of the Physician Group. The physicians providing
services for the Physician Groups do not maintain other practices. The owners of
the Physician Groups are physicians, and each Physician Group has a physician
medical director. It is the responsibility of the owners of the Physician Group
to hire and manage all physicians associated with the Physician Group and to
develop operating policies and procedures and professional standards and
controls. Pursuant to each management agreement, the Physician Group indemnifies
the Company from any loss or expense arising from acts or omissions of the
Physician Group or its professionals or other personnel, including claims for
malpractice.


   Occupational Healthcare Centers

  The Company's 115 occupational healthcare centers provide treatment for work-
related injuries and illnesses, physical and rehabilitation therapy,
preplacement physical examinations and evaluations, case management, diagnostic
testing, drug and alcohol testing and various other employer-requested or
government-mandated occupational health services. During the twelve months ended
December 31, 1996, 53% of all patient visits to the Company's centers were for
the treatment of injuries or illnesses and 47% were for physical examinations
and other non-injury occupational medical services.

  Preplacement physical examinations and drug and alcohol testing are most
frequently conducted on a walk-in basis but may be scheduled in advance. More
specialized services, such as audiogram testing or pulmonary function testing,
are usually scheduled in advance. Employees suffering from work-related injuries
or illnesses are treated on an urgent basis. The most common treatments to
employees are for soft tissue injuries, lacerations (including tendon repairs),
moderate trauma injuries to the spine or extremities, and exposure to hazardous
material.

  A typical center ranges in size from approximately 4,000 to 8,000 square feet,
treats approximately 95 patients per day and has eight to ten examination rooms,
two minor surgical suites, two intake rooms, a laboratory, an x-ray room and
ancillary areas for reception, drug testing collection, rehabilitation and
administration. The centers generally are open from eight to 13 hours per day;
however, the Company operates a number of extended-hour centers which are open
from 16 to 24 hours per day.

  Each of the Company's centers is staffed with at least one licensed physician
who is an employee of a Physician Group and at least one licensed physical
therapist. The licensed physicians are generally trained and experienced in
occupational and industrial medicine or have emergency, family practice,
internal medicine or general medicine backgrounds. Most centers utilize a staff
of between 10 and 15 full-time persons (or their part-time equivalents),
including licensed physicians, nurses, licensed physical therapists and
administrative support personnel.


   Joint Ventures
   
  The Company's strategy is to continue to develop clusters of occupational
healthcare centers in new and existing geographic markets through the formation
of strategic joint ventures in addition to the acquisition and development of
physician practices. In selected markets in which a hospital management company,
hospital system or other healthcare provider has a significant presence, the
Company may focus its expansion efforts on the establishment of joint ventures.
Effective January 1996, the Company formed a joint venture in Tucson, Arizona
with El Dorado Hospital and Medical Center (owned by Columbia/HCA Healthcare
Corporation) to establish a network of occupational healthcare centers in the
Tucson market. Effective May 1996, the Company formed a joint venture in
Oklahoma City, Oklahoma with INTEGRIS Ambulatory Care Corporation to establish a
network of occupational healthcare centers in Oklahoma. In December 1996, the
Company entered into a joint venture with Mercy Clinics, Inc., an affiliate of
Mercy Hospital System, to establish a network of occupational healthcare centers
in the      
                                       5
<PAGE>
     
Des Moines, Iowa market. The Company is the manager of the respective hospital 
joint ventures, and as such is responsible for all of the activities associated
with the operations of the clinics. As compensation for the management of the
ventures, the Company receives a monthly fee based upon net revenues. The
Company is currently in negotiations with other joint venture candidates in
certain other markets. See "Risk Factors--Dependence on Future Acquisitions and
Joint Ventures."      


   Active Injury/Illness Management

  The Company's proprietary AIM(SM) program offers proactive management of every
occupational injury or illness, from the initial physician visit until the
employee's return to work. Through the Company's proprietary management
information system, the Company administers AIM(SM) both in conjunction with the
operation of each of the Company's centers and, for a fixed fee per employee per
month, for clients whose employees are outside of the Company's center service
areas. The goal of AIM(SM) is to ensure that injured employees receive the
highest quality, appropriate healthcare while permitting the elimination of
costly inefficiencies. AIM(SM) operates on the premise that cost savings will
result if injured employees are given access to quality healthcare, and the
entire injury/illness resolution process is administered and coordinated
properly. These costs savings are derived generally from a reduction in lost
time days, a decrease in legal involvement and expenses, a more rapid return of
the injured employee to regular work, the maintenance of greater worker
productivity, the prevention of disability syndrome common to injured employees
and a decrease in employers' workers' compensation premiums.

  Under the AIM(SM) program, the Company coordinates virtually every aspect of
the injury/illness resolution process. Promptly following an employee's injury,
a Physician Group physician assesses the severity of the injury and communicates
and coordinates with the Company, attending physician, employee, employer and
insurance carrier (if applicable) to identify and assess the appropriate medical
treatment plan. If the employee requires follow-up medical visits or referrals,
the Company monitors the ongoing medical treatment by the attending physician,
assists the employer in identifying potential limited duty programs for the
employee and solicits employee restriction requirements from the attending
physician. If necessary, the Company will assist the employer in placing the
employee in a limited duty program and thereafter facilitate the process of
decreasing the employee's restriction requirements so that the employee can more
quickly return to full duty.


   Other Ancillary Programs

  The Company offers other ancillary programs as discussed below. It has been
the Company's experience that, by offering a full range of programs to
complement its core occupational healthcare and case management operations, it
strengthens its relationships with existing clients and increases the likelihood
of attracting new clients. The Company anticipates expanding its ancillary
programs as needed to address occupational legislation and regulations enacted
in the future.

  Compliance With ADA.   The ADA is a federal statute that generally prohibits
employers from discriminating against qualified disabled individuals in the
areas of the job application process, hiring, discharge, compensation and job
training. The ADA became effective July 26, 1992, for employers with more than
25 employees, and now applies to all employers with 15 or more employees. The
Company, through its "ADApt Program," assists employers with ADA compliance
issues by proactively addressing ADA requirements relating to job descriptions,
pre-placement physical examinations, analysis and compliance and confidentiality
of applicant/employee information. ADApt helps employers adapt their hiring and
termination procedures, job descriptions and injury/illness management programs
in order to comply with ADA guidelines.

  Risk Assessment and Injury Prevention Programs.   The Company assists clients
in reducing workplace injuries and illnesses through its on-site risk assessment
and injury prevention programs. These programs include identifying workplace
hazards, designing plant-specific safety programs and helping clients comply
with federal and state occupational health regulations. The Company also
provides ongoing educational programs for its clients.


   Marketing

  The Company's marketing efforts are targeted primarily at employers. The
Company currently serves more than 50,000 employers, ranging from large
corporations to businesses with only a few employees. Due to the nature of its
business, the Company's marketing efforts are primarily directed toward
employers with a significant number of employees. Business derived from
employees of companies with 50 or less employees is generally due to a center's
location, name recognition, quality service and convenience. The Company has 92
full-time sales and marketing personnel for its centers, who receive annual
salaries plus commissions or bonuses. Marketing efforts consist primarily of
direct sales calls and seminars on occupational healthcare issues. In 

                                       6
<PAGE>
 
addition, the Company periodically distributes follow-up questionnaires to
employers and patients to monitor and enhance medical care and service
satisfaction levels.


Information Services

  The Company has developed proprietary management and patient billing
information systems to monitor and process each case that the Company manages
and to administer a significant portion of the Company's receivables. As part of
these systems, the Company employs a personal computer network to transmit
patient and billing information from certain of its centers via a
telecommunications network to the Company's various central business offices.
The Company employs a Chief Information Officer who evaluates the Company's
current systems and prospective business information needs and whose staff
refines and enhances the systems to address changing information requirements.

  The Company is currently establishing a wide area network ("WAN") in each
market it serves. All centers in a market will utilize a patient administration
system (called "OccuSource(SM)") which runs on a client/server architecture
allowing each center to access and share a common database for its market. The
database contains employer protocols, patient records and other information
regarding the Company's operations in such market. Creating a WAN in each market
allows the centers in the market to share information and thereby improve center
and physician efficiencies and enhance customer service. The Company is linking
each market WAN into a nationwide WAN in order to create a centralized
repository of Company data located at the Company's principal offices in Dallas,
Texas, to be used, among other things, for clinical outcomes analysis. As of
December 31, 1996, OccuSource(SM) was fully operational in 65 centers and 15
markets. Efforts are currently underway to fully integrate OccuSource(SM) with
the Company's other information systems, including case management and billing.
The Company believes that its commitment to continued development of its
information services provides a unique and sustainable competitive advantage
within the occupational healthcare industry.


Competition

  The market to provide healthcare services within the workers' compensation
system is highly fragmented and competitive. The Company's competitors have
typically been independent physicians, hospital emergency departments and
hospital medical centers. The Company believes that, as integrated networks are
developed, its competitors will increasingly consist of specialized provider
groups, insurance companies, HMOs and other managed care providers.

  The Company competes on the basis of its specialization in the occupational
healthcare industry, knowledge and expertise, effectiveness of services, ability
to offer services in multiple markets and information systems. The Company
believes that it has a unique competitive advantage by specializing in and
focusing on occupational medicine at the primary care provider level, which is
the entry point to the occupational healthcare delivery system.

  The recruiting of physicians, nurses, physical therapists and other healthcare
providers can be competitive, although the Company has experienced less
difficulty in recruiting as the Company has grown and its reputation has
developed. The loss of services provided by physicians, other providers or
physical therapists for an extended period of time, or the inability to attract
such individuals, could have an adverse effect on the Company's business.


Laws and Regulations

   General

  As a participant in the healthcare industry, the Company's operations and
relationships are subject to extensive and increasing regulation by a number of
governmental entities at the federal, state and local levels. The Company is
also subject to laws and regulations relating to business corporations in
general. The Company believes that its operations are in material compliance
with applicable laws. Nevertheless, because of the special nature of the
Company's relationship with the Physician Groups, many aspects of the Company's
business operations have not been the subject of state or federal regulatory
interpretation and there can be no assurance that a review of the Company's or
the Physician Groups' business by courts or regulatory authorities will not
result in a determination that could adversely affect the operations of the
Company or the Physician Groups or that the healthcare regulatory environment
will not change so as to restrict the Company's or the Physician Groups'
existing operations or their expansion.

   Workers' Compensation Legislation

  The federal government and each state in which the Company does business
administer workers' compensation programs, which require employers to cover
medical expenses, lost wages and other costs resulting from work-related
injuries, illnesses and disabilities. Medical costs are paid to healthcare
providers through the employer's purchase of insurance from private workers'
compensation carriers, participation in a state fund or by self-insurance.
Changes in workers' compensation laws or regulations may create a greater or
lesser demand for some or all of the Company's services, require the Company to
develop new or modified services to meet the needs of the marketplace and
compete effectively or modify the fees that the Company may charge for its
services.

  Many states are considering or have enacted legislation reforming their
workers' compensation laws. These reforms generally give employers greater
control over who will provide medical care to their employees and where those
services will be provided, and attempt to contain medical costs associated with
workers' compensation claims. At present, ten of the states in which the Company
does business have implemented treatment-specific fee schedules that set maximum
reimbursement levels for healthcare services. The federal government and four
states provide for a "reasonableness" review of medical costs paid or
reimbursed by workers' compensation. When not governed by a fee schedule, the
Company adjusts its charges to the usual and customary levels authorized by the
payor.


   Corporate Practice of Medicine and Other Laws

  Most states limit the practice of medicine to licensed individuals or
professional organizations comprised of licensed individuals. Many states also
limit the scope of business relationships between business entities such as the
Company and licensed professionals and professional corporations, particularly
with respect to fee-splitting between a physician and another person or entity
and non-physicians exercising control over physicians engaged in the practice of
medicine.

  Laws and regulations relating to the practice of medicine, fee-splitting and
similar issues vary widely from state to state, are often vague, and are seldom
interpreted by courts or regulatory agencies in a manner that provides guidance
with respect to business operations such as those of the Company. Although the
Company attempts to structure all of its operations so that they comply with the
relevant state statutes and believes that its operations and planned activities
do not violate any applicable medical practice, fee-splitting or similar law,
there can be no assurance that (i) courts or governmental officials with the
power to interpret or enforce these laws and regulations will not assert that
the Company or certain transactions in which it is involved are in violation of
such laws and regulations and (ii) future interpretations of such laws and
regulations will not require structural and organizational modifications of the
Company's business. In addition, the laws and regulations of some states could
restrict expansion of the Company's operations into those states.


   Fraud and Abuse Laws

  A federal law (the "Anti-Kickback Statute") prohibits any offer, payment,
solicitation or receipt of any form of remuneration to induce or in return for
the referral of Medicare or other governmental health program patients or
patient care opportunities, or in return for the purchase, lease or order of
items or services that are covered by Medicare or other governmental health
programs. Violations of the statute can result in the imposition of substantial
civil and criminal penalties. In addition, as of January 1, 1995, certain anti-
referral provisions (the "Stark Amendments") prohibit a physician with a
"financial interest" in an entity from referring a patient to that entity for
the provision of any of 11 "designated medical services" (some of which are
provided by Physician Groups affiliated with the Company).

  Four of the states in which the Company conducts business (Texas, Arizona, New
Jersey and Maryland) have enacted statutes similar in scope and purpose to the
Anti-Kickback Statute. There is no authority interpreting these statutes in a
manner directly relevant to the Company's business. The Company believes that
regulatory authorities and state courts interpreting these statutes may regard
federal law under the Anti-Kickback Statute as persuasive, and further believes
that its arrangements with the Physician Groups comply with the "management
contract" safe harbor promulgated under the Anti-Kickback Statute. In addition,
most states have statutes, regulations or professional codes that restrict a
physician from accepting various kinds of remuneration in exchange for making
referrals. Several states are considering legislation that would prohibit
referrals by a physician to an entity in which the physician has a specified
financial interest.

                                       8
<PAGE>
 
  All of the foregoing laws are subject to modification and interpretation, have
not often been interpreted by appropriate authorities in a manner directly
relevant to the Company's business, and are enforced by authorities vested with
broad discretion. The Company has attempted to structure all of its operations
so that they comply with all applicable state anti-referral prohibitions. The
Company also continually monitors developments in this area. If these laws are
interpreted in a manner contrary to the Company's interpretation, reinterpreted,
or amended, or if new legislation is enacted with respect to healthcare fraud
and abuse or similar issues, the Company will seek to restructure any affected
operations so as to maintain compliance with applicable law. No assurance can be
given that such restructuring will be possible, or, if possible, will not
adversely affect the Company's business.


  Uncertainties Related to Changing Healthcare Environment

  In recent years, the healthcare industry has experienced change. Although
managed care has yet to become a major factor in occupational healthcare, the
Company anticipates that managed care programs, including capitation plans, may
play an increasing role in the delivery of occupational healthcare services, and
competition in the occupational healthcare industry may shift from individual
practitioners to specialized provider groups such as those managed by the
Company, insurance companies, HMOs and other significant providers of managed
care products. To facilitate the Company's managed care strategy, the Company is
developing risk-sharing products for the workers' compensation industry that
will be marketed to employers, insurers and managed care organizations. No
assurance can be given that the Company will prosper in the changing healthcare
environment or that the Company's strategy to develop managed care programs will
succeed in meeting employers' and workers' occupational healthcare needs. See
"Strategy."


   Environmental

  The Company is subject to various federal, state and local statutes and
ordinances regulating the disposal of infectious waste. If any environmental
regulatory agency finds the Company's facilities to be in violation of waste
laws, penalties and fines may be imposed for each day of violation and the
affected facility could be forced to cease operations. The Company believes that
its waste handling and discharge practices are in material compliance with
applicable law.


   ERISA

  The provision of goods and services to certain types of employee health
benefit plans is subject to the Employee Retirement Income Security Act of 1974
("ERISA"). ERISA is a complex set of laws and regulations subject to periodic
interpretation by the Internal Revenue Service and the Department of Labor
("DOL"). ERISA regulates certain aspects of the relationship between the
Company's managed care contracts and employers that maintain employee benefit
plans subject to ERISA. DOL is engaged in ongoing ERISA enforcement activities
that may result in additional constraints on how ERISA-governed benefit plans
conduct their activities. There can be no assurance that future revisions to or
judicial or regulatory interpretations of ERISA will not have a material adverse
effect on the Company's business or results of operations.


Seasonality

  The Company's business is seasonal in nature. Patient visits at the Company's
centers are lower in the first and fourth quarters, primarily because of fewer
occupational injuries and illnesses during those time periods due to plant
closings, vacations, and holidays. In addition, employers generally hire fewer
employees in the fourth quarter, thereby reducing the number of pre-hiring
physical examinations and drug and alcohol tests conducted at the Company's
centers during that quarter. Although the Company's rapid growth may obscure the
effect of seasonality in the Company's financial results, the Company's first
and fourth quarters generally reflect lower net revenues on a same market basis
when compared to the Company's second and third quarters.

Properties

  The Company leases approximately 35,000 square feet of office space for its
executive offices in Dallas, Texas, under a lease expiring in 1998. Of the
Company's 115 centers, 108 are leased for terms of one to ten years, and the
remaining seven centers are owned by the Company. A typical center ranges in
size from approximately 4,000 to 8,000 square feet. The Company believes that
its facilities are adequate for its reasonably foreseeable needs.

Insurance

  The Physician Groups maintain medical malpractice insurance under one
insurance policy in the amount of $1,000,000 per occurrence and $15,000,000 in
the aggregate. Pursuant to the management agreements between the Company and the
Physician Groups, each Physician Group has agreed to indemnify the Company from
certain losses, including medical malpractice. In addition, the Company
maintains an umbrella policy that provides excess medical malpractice insurance
in the amount of $10,000,000 per occurrence and $10,000,000 in the aggregate and
$3,000,000 of general liability insurance. See "Operations--Agreements With
Physician Groups."

  The Company is party to certain claims and litigation in the ordinary course
of business. The Company is not involved in any legal proceeding that it
believes will result, individually or in the aggregate, in a material adverse
effect upon its financial condition or results of operations.

Employees

  The Company has approximately 2,600 employees. None of these employees are
subject to a collective bargaining agreement, and the Company has experienced no
work stoppages. The Company believes that its employee relations are good. All
physicians, physician assistants and physical therapists are either employed by
or contract with the Physician Groups.

RISK FACTORS

   Dependence on Future Acquisitions and Joint Ventures

  The Company's growth in new and existing markets is dependent upon an
aggressive acquisition and joint venture strategy. The Company is in various
stages of negotiations to acquire practices from a number of prospective selling
groups. There can be no assurance that further suitable acquisition candidates
can be found, that acquisitions can be financed or consummated on favorable
terms or that such acquisitions, if completed, will be successful. In addition,
the Emerging Issues Task Force of the Financial Accounting Standards Board is
currently evaluating certain matters relating to the physician practice
management industry, including a review of accounting for business combinations.
The Company is unable to predict the impact, if any, that this review may have
on the Company's acquisition strategy.

  The Company has also entered into, and is in various stages of negotiations to
form, joint ventures to own and operate occupational healthcare centers in
selected markets. The Company's strategy is to form these joint ventures with
competitively positioned hospital management companies, hospital systems and
other healthcare providers. There can be no assurances that the Company will
continue to utilize joint ventures as part of its growth strategy, that further
suitable joint ventures can be formed or that such ventures will be successful.
See "Strategy" and "Operations--Joint Ventures."

   Uncertainties Related to Changing Healthcare Environment

   The healthcare industry has experienced substantial changes in recent years.
Although managed care has yet to become a major factor in occupational
healthcare, the Company anticipates that managed care programs, including case
rate and capitation plans, may play an increasing role in the delivery of
occupational healthcare services, and that competition in the occupational
healthcare industry may shift from individual practitioners to specialized
provider groups such as those managed by the Company, insurance companies, HMOs
and other significant providers of managed care products. To facilitate the
Company's managed care strategy, the Company is developing risk-sharing products
for the workers' compensation industry that will be marketed to employers,
insurers and managed care organizations. No assurance can be given that the
Company will prosper in the changing healthcare environment or that the
Company's strategy to develop managed care programs will succeed in meeting
employers' and workers' occupational healthcare needs. See "Strategy."

  There have been numerous initiatives at the federal and state levels for
comprehensive reforms affecting the payment for and availability of healthcare
services. The Company believes that such initiatives will continue during the
foreseeable future. Aspects of certain of these reforms as proposed in the past
could, if adopted, adversely affect the Company. See "Laws and Regulations."

   Government Regulation

  The provision of healthcare services is heavily regulated at both the state
and federal levels. State and federal workers' compensation laws control many
aspects of providing medical services to the individuals covered by such laws
(including, in many cases, the amounts that may be charged for those services).
Approximately 60% of the Company's revenues in the twelve month period ended
December 31, 1996 were subject to state-mandated fee schedules prescribing
maximum reimbursable amounts for designated medical procedures. Although recent
changes in such fee schedules have not adversely affected the Company, there can
be no assurances that prospective changes will not have such an effect. State
laws generally prohibit anyone other than a licensed physician from engaging in
acts that constitute the practice of medicine and also prohibit physicians from
"splitting" their fees with other persons. The Company is also subject to
various other federal and state laws. Many of the applicable laws are enforced
by regulatory authorities with broad discretion to interpret the laws and
promulgate corresponding regulations, and violations of these laws and
regulations may result in substantial penalties. The Company believes that its
operations are in material compliance with currently applicable laws and
regulations. There can be no assurance, however, that a court or regulatory
authority will not determine that the Company's operations are not in compliance
with any applicable law or regulation or that any such determination will not
have a material adverse effect on the Company. See "Laws and Regulations."

  Uncertainties Regarding Healthcare Reform

  There have been numerous initiatives at the federal and state levels for
comprehensive reforms affecting the payment for and availability of healthcare
services.  The Company believes that such initiatives will continue during the
foreseeable future.  Aspects of certain of these reforms as proposed in the past
could, if adopted, adversely affect the Company.

                                       11
<PAGE>
 
   Risks Inherent in Provision of Medical Services

  The Physician Groups and certain employees of the Company, are involved in the
delivery of healthcare services to the public and, therefore, are exposed to the
risk of professional liability claims. Claims of this nature, if successful,
could result in substantial damage awards to the claimants which may exceed the
limits of any applicable insurance coverage. Insurance against losses related to
claims of this type can be expensive and varies widely from state to state. The
Company is indemnified under its management agreements with the Physician Groups
for claims against them, maintains liability insurance for itself and negotiates
liability insurance for the physicians in the Physician Groups. Successful
malpractice claims asserted against the Physician Groups or the Company,
however, could have a material adverse effect on the Company's financial
condition and profitability. See "Operations."

   Competition

  The market to provide healthcare services within the workers' compensation
system is highly fragmented and competitive. The Company's primary competitors
have typically been independent physicians, hospital emergency departments and
hospital-owned or -affiliated medical facilities. The Company believes that, due
to the emergence of managed care, its competitors will increasingly consist of
specialized provider groups, insurance companies, HMOs and other significant
providers of managed care products. Many of the Company's current and potential
competitors are significantly larger and have greater financial and marketing
resources than the Company. There can be no assurance that the Company will be
able to compete effectively against those competitors in the future. See
"Strategy" and "Competition."

   History of Losses; Accumulated Deficit; Rapid Growth of the Company

   The Company has incurred losses in two of the past five fiscal years.  The
Company has achieved profitability in three of the past five years despite
recording a significant loss in 1993 due to nonrecurring charges of $20,473,000.
Of these charges, $19,030,000 were principally incurred in connection with the
noncash write-down of goodwill, principally related to the Company's
acquisitions in Milwaukee, Denver, Albuquerque and San Antonio.  The remaining
$1,543,000 related primarily to noncash write-downs of property and equipment of
$594,000, certain personnel costs (including severance payments made to
terminated employees), and certain other costs associated with the cessation of
service and relocation of three centers.  During the five years ended December
31, 1996 the Company incurred aggregate losses of  approximately $5.8 million.
Over the past five years, the Company has experienced rapid growth.  In view of
the Company's significant recent growth and the impact of nonrecurring charges
on the Company's 1993 results, the Company's historical financial performance
may not be indicative of its future performance.


   Dependence Upon Key Personnel

  The Company is dependent to a substantial extent upon the continuing efforts
and abilities of certain key management personnel. In addition, the Company
faces strong competition for experienced employees with technical expertise in
the workers' compensation and managed care areas. The Company has obtained a
"key man" life insurance policy on the life of John K. Carlyle, the Company's
Chairman and Chief Executive Officer. This policy provides benefits of $1
million upon the death of Mr. Carlyle, and names the Company as sole
beneficiary. Nevertheless, the loss of, or the inability to attract, qualified
employees could have a material adverse effect on the Company's business.

   Shares Eligible for Future Sale

   Sales of substantial amounts of Common Stock in the public market following
this offering, or the perception that such sales could occur, could adversely
affect prevailing market prices of the Common Stock.  The Company is unable to
make any prediction as to the effect, if any, that future sales of Common Stock
or the availability of Common Stock for sale may  have on the market price of
the Common Stock prevailing from time to time.  Certain existing stockholders
have the right to require the Company to register their Common Stock from time
to time.

   Dividend Policy and Restrictions

  The Company does not intend to pay cash dividends on the Common Stock in the
foreseeable future and anticipates that future earnings will be retained to
finance future operations and expansion. The Company's loan agreement with
Creditanstalt-Bankverein prohibits the Company from paying dividends and making
other distributions on its Common Stock.

                                       12
<PAGE>
 
   Anti-Takeover Provisions

  Certain provisions of the Company's Certificate of Incorporation and certain
provisions of the Delaware General Corporation Law may make it difficult to
change control of the Company and replace incumbent management. For example, the
Company's Certificate of Incorporation provides for a staggered Board of
Directors and permits the Board of Directors, without stockholder approval, to
issue additional shares of Common Stock or establish one or more series of
Preferred Stock having such number of shares, designations, relative voting
rights, dividend rates, liquidation and other rights, preferences and
limitations as the Board of Directors may determine.

  In addition, the terms of certain indebtedness of the Company may require
prepayment upon a change of control of the Company and therefore may have an
anti-takeover effect.

   Forward-Looking Information

   Statements contained in this Annual Report on Form 10-K that are not based on
historical facts are forward-looking statements subject to uncertainties and
risks including, but not limited to, product and service demand and acceptance,

constraints or difficulties, results of financing efforts, and other risks
described in this Annual Report on Form 10-K.

Item 2.  Properties

         The Company leases approximately 35,000 square feet of office space for
its executive offices in Dallas, Texas under a lease expiring in 1998. Of the
Company's 115 centers, 108 are leased for terms of one to ten years, and the
remaining seven centers are owned by the Company. A typical center ranges in
size from approximately 4,000 to 8,000 square feet. The Company believes that
its facilities are adequate for its reasonably foreseeable needs.

Item 3.  Legal Proceedings

         The company is party to certain claims and litigation in the ordinary
course of business. The Company is not involved in any legal proceeding that it
believes will result, individually or in the aggregate, in a material adverse
