ITEM 1. BUSINESS

A. GENERAL

     Concentra Managed Care, Inc. (the "Company" or "Concentra")* is the leading
provider of healthcare  management and cost containment services to the workers'
compensation,  auto insurance and disability  insurance markets.  The Company is
also the leading provider of  out-of-network  medical claims review to the group
health marketplace and performs  non-injury  healthcare services for over 80,000
local employers. Concentra offers a continuum of services to employers, insurers
and third-party  administrators  ("TPAs") of all sizes.  The Company's  services
allow   customers  to  increase  the  direction  of  care  for  injury   claims,
aggressively  manage the treatment  plan and thereby  control the total costs of
those claims, and review medical claims  retrospectively,  thus reducing overall
workers'  compensation,  auto  insurance,  disability and  out-of-network  group
health costs. The Company has demonstrated that by both providing healthcare and
offering claims management services,  Concentra is in a unique position to offer
and provide a full  continuum  of services  on a bundled or  unbundled  basis to
national or regional accounts and local employers.

     Concentra's   comprehensive   services  are  comprised  of  three  distinct
categories: (i) healthcare services, (ii) specialized cost containment services,
and (iii) field case management services.  For the year ended December 31, 1998,
revenues from healthcare  services,  specialized  cost-containment  services and
field case management  services  represented  approximately  43%, 30% and 27% of
total revenues, respectively.

     Healthcare services are provided through the Company's network of 169 owned
and managed occupational healthcare centers,  located in 50 markets in states as
of March 15, 1999.  Healthcare services include injury care and physical therapy
services  for  work-related  injuries  and  illnesses,   physical  examinations,
substance abuse testing and certain other loss-prevention services.

     Specialized cost containment  services are comprised of the Company's first
report of injury service provided  through its First Notice Systems*  subsidiary
("First  Notice"),  telephonic  case management  services,  provider bill review
services,  preferred provider  organization ("PPO") access through the Company's
Focus Healthcare  Management*  subsidiary ("Focus"),  out-of-network bill review
services through the Company's  Concentra  Preferred Systems subsidiary ("CPS").
independent medical exams ("IMEs") and peer reviews CPS provides  out-of-network
medical bill review services primarily to the group health market, but Concentra
is now marketing  this service to its workers'  compensation  and auto insurance
customers.

     Field case  management  services are provided to a national  customer  base
utilizing  over  1,100  full time field  case  managers.  Field case  management
services  involve  working on a  one-on-one  basis with  injured  employees  and
facilitating   communication  among  their  various  healthcare   professionals,
employers and insurance company  adjusters.  Field case management  services are
designed  both  to  assist  in  maximizing   medical   improvement   and,  where
appropriate, to expedite return to work.

     On March 2, 1999,  Concentra  entered into an Agreement  and Plan of Merger
(the "Merger  Agreement") with Yankee Acquisition Corp., a Delaware  corporation
("Yankee").  On March 24, 1999,  Concentra  entered into an Amended and Restated
Agreement  and Plan of Merger (the  "Amended  Merger  Agreement")  with  Yankee,
amending the Merger  Agreement.  The Amended Merger  Agreement  contemplates the
merger  (the  "Merger")  of Yankee with and into  Concentra.  As a result of the
Merger,  each outstanding share of Concentra Common Stock will be converted into
the right to receive $16.50 in cash. The Merger is conditioned upon, among other
things  approval by the  stockholders  of  Conentra,  receipt of  financing  and
certain regulatory approvals.  The transaction is structured to be accounted for
as a recapitaliztion.

B. INDUSTRY OVERVIEW


WORKERS' COMPENSATION

     Workers' compensation is a state-mandated,  comprehensive insurance program
that  requires  employers to fund medical  expenses,  lost wages and other costs
resulting from work-related injuries and illnesses.  Since their introduction in
the early 1900s,  these  programs have been  expanded to all fifty  states,  the
District of Columbia and Canada. In addition,  federal statutes provide workers'
compensation  benefits  for federal  employees.  Each state is  responsible  for
implementing and regulating its own program. Consequently, workers' compensation
benefits and arrangements  vary on a  state-by-state  basis and are often highly
complex.

     Workers' compensation legislation generally requires employers, directly or
indirectly through an insurance  vehicle,  to fund all of an employee's costs of
medical treatment and a significant  portion of lost wages, legal fees and other
associated  costs.  Typically,  work-related  injuries are broadly defined,  and
injured or ill  employees  are entitled to  extensive  benefits.  Employers  are
required,  directly or  indirectly,  to provide  first-dollar  coverage  with no
co-payment  or  deductible  due from the  injured or ill  employee  for  medical
treatment and, in many states, there is no lifetime limit on expenses.  However,
in exchange for providing this coverage for employees, employers are not subject
to litigation by employees for benefits in excess of those provided  pursuant to
the relevant state statute. In most states, the extensive benefits coverage (for
both  medical  costs  and lost  wages)  is  provided  through  the  purchase  of
commercial  insurance  from  private  insurance   companies,   participation  in
state-run insurance funds or employer self-insurance.

     According to statistics  published in the 1998 Workers'  Compensation  Year
Book, total workers'  compensation  costs to employers in the United States were
estimated to be  approximately  $92 billion in 1996.  Although the industry as a
whole  is  fragmented  with  a  large  number  of  competitors  in  the  various
sub-segments of workers'  compensation  services,  Concentra believes that it is
the only  integrated  provider of  healthcare  management  and  cost-containment
services offering a full continuum of services on a nationwide basis.


OCCUPATIONAL HEALTHCARE

     Occupational healthcare is largely provided by independent physicians,  who
have  experienced  increasing  pressures in recent  years from cost  containment
efforts, growing regulatory complexity,  and increased competition.  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.

     Occupational  healthcare  services consist 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.

     INJURY CARE

     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).

     As workers'  compensation costs increase,  Concentra 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. The
Company  believes  that clients' use of its  healthcare  services at the primary
care level, focusing on proactively managing each injury episode and encouraging
early  return to work (as  appropriate),  can result in  substantial  savings in
indemnity and medical costs.

                                       2


<PAGE>


     Provider reimbursement methods vary on a state-by-state basis. Forty states
have  adopted fee  schedules  pursuant  to which all  healthcare  providers  are
uniformly  reimbursed.  The 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,  customary and reasonable ("UCR") fees charged in the particular state in
which the services are provided. Of the 25 states in which the Company currently
operates occupational healthcare centers, 21 have fee schedules.

     Limitations on an employee's right to choose a specific healthcare provider
are  dependent  upon the  particular  state  statute.  According to the Workers'
Compensation  Research  Institute,  as of March  1999,  25  states  limited  the
employee's  choice of provider and 32 states  placed  restrictions  on switching
providers,  including  provisions  requiring  employer approval for any changes.
Twelve  states  place  restrictions  on  switching  providers  via managed  care
arrangements.  Generally,  the employer will also have the ability to direct the
employee when the employer is  self-insured.  Concentra  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 care.

     NON-INJURY HEALTHCARE SERVICES

     Non-injury  occupational  healthcare  services  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  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.


MANAGED CARE SERVICES: SPECIALIZED COST CONTAINMENT AND FIELD CASE MANAGEMENT

     Managed  care  techniques  are  intended to control the cost of  healthcare
services and to measure the performance of providers  through  intervention  and
on-going  review of  services  proposed  and  actually  provided.  Managed  care
techniques  were  originally  developed  to  stem  the  rising  costs  of  group
healthcare.  Historically,  employers were slow to apply managed care techniques
to  workers'  compensation  costs  primarily  because  the  aggregate  costs are
relatively  small compared to those  associated  with group health  benefits and
because state-by-state regulations related to workers' compensation are far more
complex than those related to group health.  However, in recent years, employers
and insurance carriers have been increasing their focus on applying managed care
techniques to control their workers' compensation costs.

     A number of states have adopted legislation encouraging the use of workers'
compensation managed care organizations ("MCOs") in an effort to allow employers
to  control  their  workers'  compensation  costs.  MCO laws  generally  provide
employers an opportunity to channel injured employees into provider networks. In
certain  states,  MCO laws  require  licensed  MCOs to offer  certain  specified
services,  such as  utilization  management,  case  management,  peer review and
provider bill review. Most of the MCO laws adopted to date establish a framework
within which a company such as Concentra  can provide its customers a full range
of managed care services for greater cost control.

     Because workers'  compensation benefits are mandated by law and are subject
to extensive  regulation,  payors and employers do not have the same flexibility
to alter benefits as they have with other health benefit programs.  In addition,
workers' compensation programs vary from state to state, making it difficult for
payors and multi-state employers to adopt uniform policies to administer, manage
and control the costs of  benefits.  As a result,  managing the cost of workers'
compensation  requires  approaches  that  are  tailored  to the  specific  state
regulatory environment in which the employer operates.

     Workers'  compensation  managed care services include two broad categories:
specialized  cost  containment  services  and field  case  management  services.
Specialized  cost  containment  services  are  designed  to  reduce  the cost of
workers'  compensation  claims  through a variety  of  techniques  such as first
report  of  injury  services,   utilization  management   (precertification  and
concurrent  review),   retrospective  bill  review  services,   telephonic  case

                                       3



<PAGE>

management,  PPO network access,  out-of-network bill review services,  IMEs and
peer reviews.  Field case  management  services  involve working on a one-on-one
basis with injured employees and facilitating  communication among their various
healthcare professionals,  employers and insurance company adjusters. Field case
management   services  are  designed  both  to  assist  in  maximizing   medical
improvement and, where appropriate, to expedite return to work.


GROUP HEALTH COST CONTAINMENT SERVICES

     All healthcare payors have out-of-network exposure due to healthcare claims
that are outside their  coverage area or network either as a matter of choice on
the part of the  insured or as a result of  geographic  circumstances  where the
insured  does not have  local  access to  contracted  providers.  Out-of-network
healthcare  claims  expose  payors to  greater  incidence  of  over-utilization,
cost-shifting,  omission of appropriate  discounts and possible  billing errors.
Out-of-network  bill review service  providers produce savings for their clients
by analyzing  these  out-of-network  medical claims and reducing the costs which
otherwise would be payable through a variety of methods,  including professional
negotiation, line item analysis, specialized audit and bill review processes and
broad access to preferred provider networks.


AUTO MANAGED CARE SERVICES

     The automobile insurance industry, like the workers' compensation industry,
is regulated on a  state-by-state  basis.  Although  regulatory  approval is not
required for Concentra to offer most of its services to the automobile insurance
market  (including  voluntary  network  access),  state  regulatory  approval is
required in order to offer  automobile  insurers'  products  that permit them to
direct claimants into a network of medical providers.

     It is  relatively  recent  that  the auto  insurance  market  has  provided
legislative  support of  healthcare  management  and cost  management  services.
However, in states that have adopted auto managed care legislation, direction of
care to  designated  providers of  treatment  have lowered the costs of Personal
Injury Protection  coverage.  The lowering of this threshold has an impact as to
whether  further  damages  claims can be made with regard to injury costs.  As a
result of  performance in the states of Colorado and Hawaii,  new  opportunities
have arisen in other states with  existing  no-fault  legislation.  Concentra is
pursuing  auto-related business using cost management strategies in those states
that permit such programs.


C. CONCENTRA'S BUSINESS STRATEGY

     Concentra's  objective  is  to  capitalize  on  its  national  presence  by
providing an integrated platform of comprehensive healthcare management and cost
containment  services.   The  Company's  strategy  is  to  (i)  increase  market
penetration of early intervention  services such as healthcare  services,  first
report  of  injury  and  telephonic  case   management,   (ii)  increase  market
penetration of out-of-network bill review services to the group health, workers'
compensation and auto insurance markets, (iii) streamline patient care, outcomes
reporting and claims resolution through enhanced  information  technology,  (iv)
continue  to acquire  and  develop  occupational  healthcare  centers and expand
healthcare network services by developing direct  affiliations with primary care
physicians,  specialists,  hospitals  and  other  ancillary  providers  and  (v)
capitalize on the Company's  national  organization and local market presence to
win  new  customers  and to  increase  cross-selling  of  services  to  existing
accounts. Concentra will seek to implement this strategy as follows:

INCREASE MARKET PENETRATION OF EARLY INTERVENTION SERVICES

     Concentra  intends to  increase  its  development  and  marketing  of early
intervention services,  such as access to its network of occupational healthcare
centers  and  other  providers  in its PPO  network,  first  report  of  injury,
precertification,  and telephonic case management.  Early  intervention  enables
Concentra  to  identify  promptly  cases  that have the  potential  to result in
significant  expenses and to take appropriate measures to control these expenses
before they are incurred.  In addition,  Concentra believes that providing early
intervention  services generally results in the Company obtaining earlier access
to claims  files.  Such earlier  access  improves the Company's  opportunity  to
provide  the  full  range of its  healthcare  management  and  cost  containment
services, which should result in lowering the total costs of the claim.


INCREASE MARKET PENETRATION OF OUT-OF-NETWORK BILL REVIEW SERVICES

     Concentra will further  expand its reach into the group health  marketplace
by offering new and existing  customers CPS's  comprehensive  retrospective bill
review services which will help customers contain costs


                                       4



<PAGE>

related to out-of-network group health medical charges. CPS is the market leader
in this  line of  business  and is  expanding  its  services  into the  workers'
compensation   market  and  auto  insurance  market  in  states  that  have  not
established  fee  schedules.  Concentra  believes that  expansion in these areas
represents a significant opportunity for the Company in the future.


STREAMLINE PATIENT CARE, OUTCOMES REPORTING AND CLAIMS RESOLUTION THROUGH
ENHANCED INFORMATION TECHNOLOGY

     Concentra's  ongoing  development of enhanced  information  technology will
strengthen  the  Company's  ability to provide a full  continuum  of  integrated
services to its customers.  Concentra  will continue to develop its  information
systems  to make  more  effective  use of the  Company's  extensive  proprietary
knowledge base relating to workplace  injuries,  treatment  protocols,  outcomes
data and the workers'  compensation  system's complex web of regulations.  These
enhanced  information  systems will enable Concentra to streamline  patient care
and  outcomes  reporting,  thus  augmenting  the  Company's  ability  to furnish
high-quality,  efficient  healthcare services in compliance with the regulations
governing  healthcare  services.   Further,   Concentra  believes  it  can  more
efficiently process bill review and field case management claims through the use
of enhanced  information  technology  and will  continue to devote  resources to
improving such systems.


CONTINUE TO ACQUIRE AND DEVELOP OCCUPATIONAL HEALTHCARE CENTERS AND EXPAND
HEALTHCARE NETWORK SERVICES

     Concentra  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 will continue to
acquire and develop occupational  healthcare centers in new and existing markets
and will continue to organize its occupational healthcare 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.  In
addition,  Concentra will develop occupational healthcare centers in new markets
and within existing  markets  through joint ventures and management  agreements.
Finally,    through    Focus,    Concentra   will   continue   to   expand   its
vertically-integrated  networks of specialists,  hospitals and other  healthcare
providers.  These networks, and the Company's  occupational  healthcare centers,
are designed to provide quality care to patients,  while reducing total costs to
employers and insurers.


CAPITALIZE ON NATIONAL ORGANIZATION AND LOCAL MARKET PRESENCE TO WIN NEW
CUSTOMERS AND TO INCREASE CROSS-SELLING OF SERVICES TO EXISTING ACCOUNTS

     Concentra  believes  that  national  and  regional  insurance  carriers and
self-insured  employers  will  benefit  greatly  from the  Company's  ability to
provide a full continuum of healthcare  management and cost containment services
on a nationwide  basis.  Concentra  offers  these large  payors a  comprehensive
solution  to their  healthcare  management  and cost  containment  needs  from a
service provider that is adept at understanding  and working with many different
and complex state legislative environments. Concentra's national organization of
local  service  locations  enables the Company to meet the needs of these large,
national payors while maintaining the local market presence necessary to monitor
changes in state-specific  regulations and to facilitate case resolution through
locally provided managed care services. Concentra's national marketing personnel
will  continue to target  these large  payors to expand the  Company's  customer
base.  In  addition,   Concentra  is   well-positioned   to  capitalize  on  the
relationships  developed  through the Company's  broad-based  national and local
marketing efforts by cross-selling  its full continuum of healthcare  management
and cost containment services to its existing customer base.


     D. SERVICES AND OPERATIONS 

     Concentra's business and operations span the workers'  compensation,  group
health, auto and disability insurance markets.  Each of these markets represents
a significant  opportunity  for the full continuum of healthcare  management and
cost  containment  services  provided by  Concentra.  In each of these  markets,
insurance companies,  self-insured  employers and TPAs have a need for Concentra
service offerings.


HEALTHCARE SERVICES

     OCCUPATIONAL HEALTHCARE CENTERS

     The Company's 169 occupational healthcare centers at March 15, 1999 provide
treatment  for   work-related   injuries  and   illnesses,   physical   therapy,
preplacement physical examinations and evaluations, certain diagnostic





                                       5



<PAGE>

testing,  drug and  alcohol  testing  and various  other  employer-requested  or
government-mandated occupational health services. During the year ended December
31, 1998,  approximately 52% of all patient visits to the Company's centers were
for the  treatment of injuries or  illnesses  and 48% were for  substance  abuse
testing,  physical  examinations  and other non-injury  occupational  healthcare
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  sometimes  scheduled  in advance.  Employees  suffering  from  work-related
injuries or illnesses are treated on an urgent basis.

     Each of Concentra's centers is staffed with at least one licensed physician
who is an employee of a  professional  association or  professional  corporation
affiliated with the Company (the  "Physician  Groups") and at least one licensed
physical   therapist.   The  licensed   physicians  are  generally  trained  and
experienced  in  occupational  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.

     Physician  and  physical  therapy  services  are  provided  at  Concentra's
occupational  healthcare  centers under  agreements  with the Physician  Groups,
which are independently  organized professional  corporations that hire licensed
physicians  and  physical  therapists  to  provide  healthcare  services  to the
centers' patients. The management agreements between Concentra and the Physician
Groups with  respect to the 300  affiliated  physicians  as of February 28, 1999
have 40-year terms. Pursuant to each management agreement,  the Company provides
a wide array of business  services to 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.  Concentra collects receivables on behalf of the Physician
Groups and  advances  funds for  payment  of each  Physician  Group's  expenses,
including salaries, shortly after services are rendered to patients. The Company
receives a management  fee based on all services  performed at the centers.  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
contractual  allowances  and  bad  debts.  Concentra  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.


     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.  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.


     JOINT VENTURES AND MANAGEMENT AGREEMENTS


     Concentra'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
or management contracts. In its joint venture relationships, Concentra typically
acquires a majority  ownership  interest in the venture and agrees to manage the
venture for a management fee based on net revenues.  Concentra  currently is the
managing member of eight joint ventures through which it operates 22 centers and
has entered  into two  management  agreements  through  which it  operates  five
centers.


     OTHER ANCILLARY PROGRAMS


     Concentra  offers other ancillary  programs as described below. It has been
the  Company's  experience  that,  by  offering  a full  range  of  programs  to
complement its core healthcare management operations, it strengthens its


                                       6



<PAGE>


relationships  with existing  clients and increases the likelihood of attracting
new clients. Concentra 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  now  applies  to all  employers  with 15 or more  employees.
Through its "ADApt  Program,"  Concentra  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.  Concentra 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.

     Healthcare services collectively represented approximately 46%, 43% and 43%
of  Concentra's  total  revenues for the fiscal years ending  December 31, 1996,
1997 and 1998, respectively.


SPECIALIZED COST CONTAINMENT SERVICES

     Concentra  provides a number of specialized  services  focused  directly on
helping to reduce the medical  and  indemnity  costs  associated  with  workers'
compensation  and the medical costs  associated with group health claims.  These
specialized  cost  containment  services  include first report of injury service
through First Notice,  utilization  management  (precertification and concurrent
review),  retrospective  bill review services,  telephonic case management,  PPO
network access through Focus,  out-of-network  bill review services through CPS,
IMEs and peer reviews.

     Concentra  is able to offer  its  services  on an  unbundled  basis or on a
bundled basis as a full-service  managed care program,  beginning with the first
report of injury and including all specialized cost containment  services needed
to  manage  aggressively  the  costs  associated  with  a  work-related  injury.
Concentra's  comprehensive  approach to  managing  workers'  compensation  costs
serves the needs of a broad range of clients,  from local  adjusters to national
accounts.  In addition to providing  specialized cost  containment  services for
work-related  injuries and illnesses,  the Company also provides  out-of-network
bill review services to the group health market,  cost  containment  services to
payors of automobile  accident  medical  claims and social  security  disability
advocacy services to payors of long term disability claims.

     Concentra  believes  that  the  demand  for  specialized  cost  containment
services  will continue to increase due to a number of factors,  including:  (i)
the increasing  payor awareness of the availability of these techniques for cost
containment  and  case  management;  (ii)  the  effectiveness  of  managed  care
techniques  at  reducing  costs  for group  health  insurance  plans;  (iii) the
verifiable  nature  of the  savings  that  can be  obtained  by  application  of
specialized cost containment techniques applicable to workers' compensation; and
(iv) the broad  applicability of these techniques to all injured employees,  not
just severely injured employees likely to be absent from work.

     FIRST REPORT OF INJURY

     Through First Notice,  Concentra  provides a  computerized  first report of
injury/loss reporting service utilizing two centralized national call centers to
which an employer or insurance company claims adjuster  communicates  reports of
injuries or losses as soon as they occur.  First  Notice  provides  its services
primarily  to the auto  industry  for  first  notice  of loss  reporting  and to
workers' compensation  carriers for first report of injuries reporting,  as well
as to  property  and  casualty  carriers  that  write  both  auto  and  workers'
compensation insurance. For injuries, each report is electronically  transferred
or mailed to the state  agency,  the employer and the  insurance  company.  This
service  assists in the timely  preparation and  distribution of  state-mandated
injury  reports and also  provides  Concentra  and its  customers  with an early
intervention  tool to  maximize  control  over  workers'  compensation  and auto
claims.

     UTILIZATION MANAGEMENT: PRECERTIFICATION AND CONCURRENT REVIEW

     Concentra's  precertification  and concurrent  review  services are used by
clients  to  ensure  that  certain  medical  procedures  are  precertified  by a
Concentra registered nurse and/or physician for medical necessity and

                                       7



<PAGE>

appropriateness   of  treatment  before  the  medical  procedure  is  performed.
Concentra's  determinations  represent only recommendations to the customer; the
ultimate  decision  to approve or  disapprove  the request is made by the claims
adjuster. Precertification calls are made by either the claimant or the provider
to one of Concentra's national  utilization  management reporting units. After a
treatment plan has been precertified,  a Concentra employee performs a follow-up
call  (concurrent  review) at the end of an  approved  time  period to  evaluate
compliance and/or discuss alternative plans.


     RETROSPECTIVE BILL REVIEW

     Through a sophisticated software program, Concentra reviews and reduces its
customers'  medical  bills  (including  hospital  bills) to either  the  various
state-mandated fee schedules for workers' compensation claims or a percentage of
the UCR  rates  that  exist  in  non-fee  schedule  states.  Additionally,  this
automated  retrospective  bill review service  enables clients to access certain
PPO pricing schedules that represent  additional savings below the fee schedules
or UCR rates. The savings to Concentra's clients as a result of this service can
be significant.  Retrospective bill review also creates an important  historical
database for provider  practice  patterns and managed care  provider  compliance
requirements.

     TELEPHONIC CASE MANAGEMENT

     This  service  provides  for  short-duration  (30  to 90  days)  telephonic
management of workers' compensation claims. The telephonic case management units
accept first reports of injury,  negotiate  discounts  with  hospitals and other
providers,  identify  care  alternatives  and work  with  injured  employees  to
minimize lost time on the job. Each of the telephonic case  management  units is
overseen  by  nurses  who  are  experienced  in  medical  case  management.  The
telephonic  case  management  units  represent an  important  component of early
intervention  and act as a referral  source of appropriate  cases to Concentra's
field case management offices.

     ACCESS TO PREFERRED PROVIDER NETWORKS

     Through Focus, Concentra provides its clients with access to a national PPO
network.  This network  provides  injured workers with access to quality medical
care and pre-negotiated  volume discounts,  thereby offering Concentra's clients
the ability to influence,  or in certain states to direct,  their employees into
the PPO network as a means of managing their work-related claims. In addition to
providing a vehicle for managing the delivery of  appropriate  care by qualified
providers,  the  discounts  associated  with  these  PPO  arrangements  generate
additional  savings  through the  retrospective  bill review  program  described
above.  Focus's  national  network  includes  approximately  219,000  individual
providers and 2,900 hospitals covering 41 states and the District of Columbia.

     OUT-OF-NETWORK BILL REVIEW

     Through  CPS,  Concentra   continues  to  expand  its  market  presence  in
retrospective  bill review  services.  CPS is the market  leader in this line of
business  in the group  health  arena and is  expanding  its  services  into the
workers'  compensation  market in states that have not established fee schedules
and into the auto insurance market where appropriate.  CPS utilizes a variety of
techniques to reduce expenses by repricing hospital and other facilities' bills.
Utilizing its comprehensive  portfolio of products, CPS reduces costs ordinarily
payable  on  medical   bills   submitted  by   healthcare   providers   and  the
administrative  expense  associated with reviewing and analyzing  medical bills.
These services include  professional fee negotiation,  line-item  analysis,  and
other  specialized  audit  and bill  review  processes,  as well as  access to a
nationwide PPO network.

     CPS provides  out-of-network  bill review services to healthcare  payors in
most risk categories:  indemnity,  PPO, health maintenance  organization,  ERISA
self-insured plans,  Taft-Hartley Plans, reinsurance carriers and intermediaries
such as  administrative  services  organizations  and TPAs.  CPS is the  largest
provider of these specific services in the managed care industry and specializes
in out-of area and non-network cost management  services that reduce exposure to
over-utilization,  upcoding, cost shifting, various forms of revenue enhancement
tactics and inflated retail charge practices.

     The current  service  delivery  model employed at CPS is designed to review
most  provider  bill types,  employ four  distinct  transmission  modalities  to
facilitate the exchange of bill data,  utilize various database  technologies as
part of the bill  screening  process,  score  each  bill  referred  based on the
individual service requirements of each client group, and route each bill to the
most  appropriate  bill review service  included in a consolidated  portfolio of
cost containment  services.  CPS has packaged this process and markets it as the
Healthcare Bill Management


                                       8



<PAGE>

System  ("HBMS".) The system  affords large payor  clients  scale and  capacity,
consolidated and uniform cost management capability,  rigorous due diligence and
superior performance.

     INDEPENDENT MEDICAL EXAMS

     IMES are provided to assess the extent and nature of an employee's injury
or illness. Concentra provides its clients with access to independent physicians
who  perform  the IMEs from 14 of the  Company's  service  locations  and,  upon
completion, prepare reports describing their findings.

     PEER REVIEWS

     Peer review services are provided by a physician,  therapist,  chiropractor
or other  provider  who  reviews  medical  files to confirm  that the care being
provided  appears to be necessary  and  appropriate.  The reviewer does not meet
with the patient, but merely reviews the file as presented.


     AUTOMOBILE INSURANCE MANAGED CARE

     Concentra offers an integrated  service to the automobile  insurance market
that,  where  permitted by law,  includes the direction of  automobile  accident
victims  into  networks of medical  providers.  The Company  currently  offers a
fully-integrated service in only 2 states and offers voluntary network access in
several other states. The Company's program has produced significant savings for
its insurance  company  clients.  Services  offered to the automobile  insurance
market  include  precertification,  telephonic  case  management,  direction  of
injured  persons into  specialized  PPO networks,  medical bill review and field
case management.  Specialized cost containment services collectively represented
approximately  22%,  29% and 30% of  Concentra's  total  revenues for the fiscal
years ending December 31, 1996, 1997 and 1998, respectively.

FIELD CASE MANAGEMENT SERVICES

     Concentra   provides  field  case  management   services  to  the  workers'
compensation insurance industry through nurse case managers working at the local
level on a one-on-one basis with injured employees and their various  healthcare
professionals, employers and insurance company adjusters. The Company's services
are designed to assist in maximizing medical improvement and, where appropriate,
to expedite  employees' return to work through medical management and vocational
rehabilitation services.

     Concentra's field case management services consist of one-on-one management
of a  work-related  injury by over 1,100 field case managers in 89 offices in 49
states,  the District of Columbia and Canada.  This service typically involves a
case  with a  significant  potential  or  actual  amount  of lost work time or a
catastrophic  injury that requires detailed management and therefore is referred
out by the local  adjuster  to the  Concentra  marketer.  Concentra  field  case
managers  specialize in expediting the injured employee's return to work through
both  medical  management  and  vocational  rehabilitation.  Medical  management
services  provided by Concentra's  field case managers include  coordinating the
efforts  of  all  the  healthcare  professionals  involved  and  increasing  the
effectiveness  of the care being provided by  encouraging  compliance and active
participation  on the  part of the  injured  worker.  Vocational  rehabilitation
services  include  job  analysis,   work  capacity  assessments,   labor  market
assessments, job placement assistance and return to work coordination.

     The  Company  believes  that  the  following  factors  will  contribute  to
continued growth of its field case management services: (i) increased acceptance
of field case  management  techniques  due to greater  exposure to the  workers'
compensation managed care market; (ii) earlier  identification of individuals in
need of field case  management  services  due to  increased  utilization  of the
Company's specialized cost containment services, particularly early intervention
services;   (iii)   increased   market   share  at  the   expense  of   smaller,
undercapitalized  competitors;  and (iv) the ability to access national accounts
for use of case management services.

     Field case management services  represented  approximately 32%, 28% and 27%
of Concentra's  total  revenues for the years ended December 31, 1996,  1997 and
1998, respectively.

     Financial information regarding the Company's segments is set forth in Note
13 of Notes to Consolidated Financial Statements, beginning on Page F-20.

E. CUSTOMERS

     Concentra's  occupational  healthcare  centers  currently  serve  more than
80,000 employers,  ranging from large corporations to businesses with only a few
employees. The Company serves more than 2,000 specialized

                                       9



<PAGE>

cost containment and  field  case management  customers across the United States
and Canada,  including most of the major  underwriters of workers'  compensation
insurance,  TPAs and self-insured employers.

     Concentra  is  compensated  primarily  on  a  fee-for-service   basis.  The
Company's largest customer represented less than 6% of Concentra's total revenue
in 1998.  The Company has not entered into written  agreements  with most of its
healthcare   services  customers.   Many  of  the  Company's   specialized  cost
containment  and  field  case  management  relationships  are  based on  written
agreements.  However,  either the customer or the Company can terminate  most of
these agreements on short notice.


F. SALES AND MARKETING

     Concentra actively markets its services primarily to workers'  compensation
insurance  companies,  TPAs,  employers  and employer  groups.  The Company also
markets to the group  health,  automobile  insurance  and  disability  insurance
markets. The Company's marketing  organization includes over 350 full-time sales
and marketing personnel.

     Concentra markets its services at both the local insurance company adjuster
and  employer  level.  In  addition,  the Company  markets  its  services at the
national and regional level for large managed care accounts and for self-insured
corporations  where  a  more  sophisticated   sales  presentation  is  required.
Concentra has a dedicated staff of national accounts salespeople responsible for
marketing and  coordinating  the  Company's  full range of services to corporate
offices.

     Concentra's  local marketing has been a critically  important  component of
the Company's strategy, because of the decision-making authority that resides at
the  local  level and the  relationship-driven  nature  of that  portion  of the
business.  However,  the expansion of  comprehensive  managed care  legislation,
continuing   receptiveness   to   workers'   compensation   change  and  a  more
comprehensive product offering by Concentra, demand that the Company continue to
focus on marketing to national  headquarters  offices of insurance companies and
self-insured companies.  As part of its coordinated marketing effort,  Concentra
periodically  distributes  follow-up  questionnaires  to patients,  insurers and
employers to monitor satisfaction with the Company's services.


G. QUALITY ASSURANCE

     Concentra  routinely  uses  internal  audits  to test  the  quality  of its
delivery of services.  The Company  conducts  audits of compliance  with special
instructions,   completion  of  activities  in  a  timely  fashion,  quality  of
reporting, identification of savings, accuracy of billing and professionalism in
contacts with healthcare providers.  The Company conducts audits on a nationwide
basis for  particular  customers or on a local office basis by selecting  random
files for review.  A detailed  report is generated  outlining the audit findings
and providing specific  recommendations for service delivery improvements.  When
appropriate,   the   Company   conducts   follow-up   audits  to   ensure   that
recommendations from the initial audit have been implemented.


H. COMPETITION


HEALTHCARE SERVICES

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

     Concentra  competes  effectively  because  of  its  specialization  in  the
occupational  healthcare  industry,  its  broad  knowledge  and  expertise,  the
effectiveness of its services as measured by favorable outcomes,  its ability to
offer  services in multiple  markets and its  information  systems.  The Company
believes that it enjoys a unique  competitive  advantage by  specializing in and
focusing on occupational healthcare at the primary care provider level, which is
the entry point to the occupational healthcare delivery system.

     The  recruiting  of  physicians,  physical  therapists,  nurses  and  other
healthcare  providers  can  be  competitive.  However,  Concentra  continues  to
experience  greater  ease in  recruiting  as the Company  grows and becomes more
widely  known  by  healthcare  providers.  The  loss  of  services  provided  by
physicians,  physical  therapists,  nurses and other  providers  for an extended
period of time,  or the  inability  to attract such  individuals,  could have an
adverse effect on the Company's business.


                                       10

SPECIALIZED COST CONTAINMENT AND FIELD CASE MANAGEMENT SERVICES

     The managed  care  services  market is  fragmented,  with a large number of
competitors.  Concentra  competes with numerous  companies,  including  national
managed care providers,  smaller independent providers, and insurance companies.
The Company's primary  competitors are companies that offer one or more workers'
compensation  managed  care  services  on a national  basis.  The  Company  also
competes  with numerous  smaller  companies  that  generally  provide  unbundled
services on a local level where such companies often have a relationship  with a
local adjuster.  Several large workers'  compensation  insurance  carriers offer
managed care services for their insurance customers either through the insurance
carrier's own personnel or by outsourcing  various services to providers such as
Concentra.  Concentra  believes that this competitive  environment will continue
into the foreseeable future.

     Concentra  competes  effectively  because of its specialized  knowledge and
expertise  in the workers'  compensation  managed care  services  industry,  the
effectiveness of its services, its ability to offer a full continuum of services
in multiple markets,  its information systems and the prices at which its offers
its services.


I. INFORMATION SYSTEMS AND TECHNOLOGY

     Concentra  maintains  a  fundamental  commitment  to  the  development  and
implementation of advanced information technology,  with a considerable focus on
web-based  applications.  These  applications  further the Company's systems and
product  integration,  enhancing  the delivery of quality  customer  service and
increasing   customer   communication  by  augmenting   Concentra's  ability  to
demonstrate cost savings across the entire episode of care.

     Concentra has  substantially  completed the  implementation  of a wide area
network ("WAN") in each market in which it provides  healthcare  services.  When
the implementation is complete, all occupational  healthcare centers in a market
will utilize a patient  administration system (named "OccuSource") 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  Concentra's  operations in the 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.  Concentra is linking each market WAN into a nationwide WAN in
order to create a centralized repository of Company data to be used, among other
things, for clinical outcomes  analysis.  Concentra believes that its commitment
to continued development of its healthcare  information system provides a unique
and  sustainable   competitive  advantage  within  the  occupational  healthcare
industry.

     Concentra has developed a new internet-based first notice of loss reporting
system for all lines of insurance (named "FNSNet").  The application extends the
Company's call center technology through the internet,  enabling users to report
first notices of loss, as well as providing  the user with  immediate  access to
customized  networks  and  routing  to  appropriate  and  qualified   healthcare
providers.  FNSNet can be accessed  through  hyperlinks on customers' web pages.
This application enhances both internal  integration and customer  communication
and creates an effective  platform for Concentra's First Notice Systems division
to handle calls with greater speed and efficiency.

     Concentra's  newly-developed  Integrated  Case  Management  Software System
("ICMS")  facilitates  and expedites the daily tasks of the Company's  field and
telephonic  case  managers,  allowing  them to devote  more  time to  consistent
delivery  of  quality  service.  This  software  allows  immediate  exchange  of
information  among Concentra's  offices,  as well as among employees in the same
office.  ICMS  is  integrated  with  the  FNSNet  web-based  product.  The  ICMS
application  enables a clear,  precise and immediate  transmission  of data from
First  Notice  into the ICMS  system.  This  pre-population  of data  eliminates
redundant and duplicative data entry for nurse case managers,  thus resulting in
greater time efficiency and cost savings.  The development and implementation of
ICMS allow for shared data in  situations  in which  multiple  case managers are
working  on a case.  The  new  ICMS  also  creates  better  customer  access  to
information and allows Concentra to produce specific,  user-friendly  reports to
demonstrate the value of the Company's services.


     Finally,  Concentra's CPS subsidiary utilizes its proprietary,  technology-
based HBMS system for its out-of-network medical claims review services.  Client
bills  are  accessed  and  entered  into HBMS in a  variety  of ways,  including
electronic bill  identification  within the client's claim  adjudication  system
with  subsequent  EDI  transfer  to  CPS,  entry  of  appropriate  bills  into a
customized, CPS-supplied Data Access Point ("DAP") system,


                                      11


<PAGE>

on-site bill entry by a CPS employee into the DAP system,  and overnight mail or
facsimile of client bills to a CPS service center.  These access  strategies are
designed to increase the number of  appropriate  bills that CPS receives,  while
minimizing the administrative  cost to the client. Once a bill is electronically
or manually entered into HBMS, the bill is evaluated  against CPS's licensed and
proprietary  databases that are designed to identify instances of cost shifting,
improper coding and utilization  and pricing issues.  Following  analysis of the
bill, the bill passes through CPS's client preference profile that is created at
the time of CPS's initial  engagement  with the client.  HBMS then evaluates the
compatibility of the service with the greatest expected savings with the service
requirements of the client and  electronically  sends the bill for processing to
the appropriate CPS service department.

J. GOVERNMENT REGULATION


GENERAL

     As a provider  of  healthcare  management  and cost  containment  services,
Concentra  is 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. Applicable laws and regulations are subject to frequent changes.

     Laws and  regulations  affecting  Concentra's  operations  fall  into  four
general categories:  (i) workers'  compensation and other laws that regulate the
provision of healthcare  services or the provision of cost containment  services
or require licensing,  certification or other approval of such services provided
by the  Company;  (ii) laws  regarding  the  provision  of  healthcare  services
generally;  (iii)  laws  regulating  the  operation  of  managed  care  provider
networks; and (iv) other laws and regulations of general applicability.


WORKERS' COMPENSATION LAWS AND REGULATIONS

     In  performing   workers'   compensation   healthcare   services  and  cost
containment  services,  Concentra must comply with state  workers'  compensation
laws.   Workers'   compensation  laws  require  employers  to  assume  financial
responsibility  for medical  costs,  a portion of lost wages and  related  legal
costs of work-related illnesses and injuries. These laws establish the rights of
workers to receive benefits and to appeal benefit denials. Workers' compensation
laws  generally   prohibit  charging  medical   co-payments  or  deductibles  to
employees.  In addition,  certain states  restrict  employers'  rights to select
healthcare  providers and establish  maximum fee levels for treatment of injured
workers.


     Many states are  considering or have enacted  legislation  reforming  their
workers'  compensation  laws.  These reforms  generally give  employers  greater
control over who will provide  healthcare  services to their employees and where
those services will be provided and attempt to contain medical costs  associated
with  workers'  compensation  claims.  At  present,  40 of the  states  in which
Concentra does business have implemented  treatment-specific  fee schedules that
set  maximum  reimbursement  levels for  healthcare  services.  The  District of
Columbia and 10 states  provide for a  "reasonableness"  review of medical costs
paid  or  reimbursed  by  workers'  compensation.  When  not  governed  by a fee
schedule,  Concentra adjusts its charges to the usual,  customary and reasonable
levels accepted by the payor.


     Many  states,  including  a number  of those in which  Concentra  transacts
business,  have licensing and other  regulatory  requirements  that apply to the
Company's  specialized  cost  containment  and field case  management  business.
Approximately  half of the states have enacted  laws that  require  licensing of
businesses that provide medical review  services,  such as Concentra's.  Some of
these laws apply to medical  review of care  covered by  workers'  compensation.
These  laws  typically   establish  minimum  standards  for   qualifications  of
personnel,  confidentiality,  internal  quality  control and dispute  resolution
procedures.  In  addition,  new laws  regulating  the  operation of managed care
provider networks have been adopted by a number of states.  These laws may apply
to managed  care  provider  networks  having  contracts  with the  Company or to
provider networks that the Company has organized and may organize in the future.
To the extent that Concentra is governed by these regulations, it may be subject
to  additional  licensing  requirements,   financial  oversight  and  procedural
standards for beneficiaries and providers.


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


                                       12



<PAGE>


the  Company  and  licensed   professionals   and   professional   corporations,
particularly   with   respect   to   fee-splitting    between   physicians   and
non-physicians.  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 Concentra's.
The Company attempts to structure all of its healthcare  services  operations to
comply with applicable state statutes regarding medical practice,  fee-splitting
and  similar  issues.  However,  there can be no  assurance  (i) that  courts or
 .governmental  officials  with the power to interpret or enforce  these laws and
regulations  will not assert that  Concentra  is in  violation  of such laws and
regulations  or (ii) that future  interpretations  of such laws and  regulations
will not require  Concentra  to modify the  structure  and  organization  of its
business.

FRAUD AND ABUSE LAWS


     A federal law (the "Anti-Kickback  Statute") prohibits the 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).


     At least six of the states in which the  Company  conducts  its  healthcare
services business (Florida, California, Texas, Arizona, New Jersey and Maryland)
have  enacted  statutes  similar  in scope and  purpose  to the  Anti-  Kickback
Statute,  with applicability to services other than those covered by Medicare or
other  governmental  health  programs.  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. Even in states
which have not enacted  such  statutes,  the Company  believes  that  regulatory
authorities and state courts  interpreting these statutes may regard federal law
under the Anti-Kickback Statute and the Stark Amendments as persuasive.

     Concentra  believes that its arrangements  with the Physician Groups comply
with the Anti-Kickback  Statute, the Stark Amendments and applicable state laws.
However,   all  of  the  foregoing   laws  are  subject  to   modification   and
interpretation,  have not often been interpreted by appropriate authorities in a
manner  applicable  to the  Company's  business and are enforced by  authorities
vested with broad  discretion.  Concentra  has attempted to structure all of its
operations  so  that  they  comply  with  all   applicable   anti-kickback   and
anti-referral prohibitions.  Concentra also continually monitors developments in
this area. If these laws are  interpreted  in a manner  contrary to  Concentra's
interpretation or are reinterpreted or amended, or if new legislation is enacted
with respect to  healthcare  fraud and abuse,  illegal  remuneration  or similar
issues, the Company will seek to restructure any affected operations to maintain
compliance   with   applicable   law.  No  assurance  can  be  given  that  such
restructuring  will be possible,  or, if  possible,  will not  adversely  affect
Concentra's business or results of operations.


SPECIALIZED COST CONTAINMENT SERVICES

     Many  of  the  Company's  specialized  cost  containment  services  include
prospective  or  concurrent  review of  requests  for  medical  care or therapy.
Approximately  half of the states  have  enacted  laws that  require  licensure,
certification or other approval of businesses, such as Concentra's, that provide
medical  review  services.  Some of these laws  apply to medical  review of care
covered  by  workers'  compensation.  These  laws  typically  establish  minimum
standards for  qualifications  of personnel,  confidentiality,  internal quality
control and dispute resolution procedures.  These regulatory programs may result
in increased costs of operation for Concentra,  which may have an adverse impact
upon the  Company's  ability to compete with other  available  alternatives  for
healthcare cost control.


USE OF PROVIDER NETWORKS

     Concentra's ability to provide comprehensive healthcare management and cost
containment  services  depends in part on its ability to contract with or create
networks of healthcare providers which share the Company's objectives.  For some
of its clients, Concentra offers injured workers access to networks of providers
who


                                       13


<PAGE>


are selected by the Company for quality of care and pricing. Laws regulating the
operation of managed  care  provider  networks  have been adopted by a number of
states.  These laws may apply to managed care provider networks having contracts
with Concentra or to provider networks that the Company may organize or acquire.
To the extent Concentra is governed by these  regulations,  it may be subject to
additional licensing requirements,  financial oversight and procedural standards
for beneficiaries and providers.


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  Concentra'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 ERISA or judicial or regulatory  interpretations  of ERISA will not
have a material adverse effect on Concentra's business or results of operations.


AUTOMOBILE INSURANCE REGULATION

     The automobile insurance industry, like the workers' compensation industry,
is regulated on a  state-by-state  basis.  Although  regulatory  approval is not
required  for the  Company  to  offer  most of its  services  to the  automobile
insurance market (including voluntary network access), state regulatory approval
is required in order to offer automobile  insurers  products that permit them to
direct claimants into a network of medical providers. To date, only Colorado and
Hawaii have  permitted  such  direction  of care,  and the  Company  offers this
managed care service to automobile insurers in those states. No assurance can be
given that other  states  will  permit  such  direction  of care for  automobile
accident  victims or, if such a program is  permitted,  that the Company will be
able  to  obtain  regulatory  approval,  if any is  required,  to  provide  such
services.


ENVIRONMENTAL

     Concentra  is subject  to various  federal,  state and local  statutes  and
ordinances  regulating the disposal of infectious  waste,  including medical and
other waste generated at the Company's  occupational  healthcare  centers. If an
environmental  regulatory  agency  finds any of the  Company's  centers 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.
Concentra  believes  that its waste  handling  and  discharge  practices  are in
material compliance with applicable law.


K. SEASONALITY

     Concentra's  healthcare  services business is seasonal in nature.  Although
Concentra's  expansion of services and continuing  growth may obscure the effect
of  seasonality  in the Company's  financial  results,  the Company's  first and
fourth quarters  generally  reflect lower net healthcare  services revenues on a
same market basis when compared to the second and third quarters.

     Plant closings, vacations and holidays during the first and fourth quarters
result in fewer patient visits at the Company's occupational healthcare centers,
primarily  because of fewer  occupational  injuries and  illnesses  during those
periods. In addition, employers generally hire fewer employees during the fourth
quarter, thereby reducing the number of pre-employment physical examinations and
drug and alcohol tests conducted at the Company's centers during that quarter.


L. INSURANCE

     The Company and the Physician Groups maintain medical malpractice insurance
in the  amount  of  $1,000,000  per  incident/$3,000,000  annual  aggregate  per
provider,  subject to an annual  aggregate  limit in the amount of  $20,000,000.
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.  The Company  maintains  an errors and
omissions  liability  insurance  policy  covering  all aspects of the  Company's
managed care services. This policy has limits of $1,000,000 per claim/$3,000,000
annual aggregate.


                                       14


<PAGE>


     In addition,  Concentra maintains $3,000,000 of general liability insurance
and an umbrella  policy that  provides  excess  insurance  coverage  for medical
malpractice  and for  errors and  omissions  in the  amount of  $20,000,000  per
occurrence and $20,000,000 in the aggregate.


M. EMPLOYEES

     Concentra had  approximately  7,800 employees at December 31, 1998. None of
Concentra's  employees  is subject to a  collective  bargaining  agreement.  The
Company  has  experienced  no work  stoppages  and  believes  that its  employee
relations are good. All physicians, physician assistants and physical therapists
providing professional services in the Company's occupational healthcare centers
are either employed by or contract with the Physician Groups.


N. RISK FACTORS


DEPENDENCE ON FUTURE ACQUISITIONS AND JOINT VENTURES; ACQUISITION RISKS

     The growth of Concentra's healthcare services in new and current markets is
dependent upon an aggressive acquisition and joint venture strategy. The success
of this acquisition  strategy will be determined by numerous factors,  including
the Company's ability to identify suitable acquisition  candidates,  competition
for such acquisitions, purchase price, the financial performance of the acquired
businesses  after  acquisition  and the  ability  of the  Company  to  integrate
effectively  the  operations  of  acquired  businesses.  Although  Concentra  is
currently  in various  stages of  negotiations  to  complete  acquisitions  from
several  prospective  selling groups,  there can be no assurance that additional
suitable acquisition  candidates can be found, that acquisitions can be financed
or consummated on favorable terms or that  acquisitions,  if completed,  will be
successful. In addition, there can be no assurance that Concentra  will be  able
to integrate  successfully  the operations of acquired  businesses  or institute
Company-wide  systems  and  procedures  to  operate  successfully  the  combined
enterprises.   A  strategy  of  growth  by acquisition also involves the risk of
assuming  unknown  or  contingent  liabilities  of  acquired   businesses.  Such
liabilities could be material,  individually or in the aggregate.

     Any failure by Concentra to identify  suitable  candidates for acquisition,
to integrate or operate  acquired  businesses  effectively or to insulate itself
from unwanted  liabilities of acquired  businesses could have a material adverse
effect on the Company's business, financial condition and results of operations.
In  addition,  the  Emerging  Issues  Task  Force  of the  Financial  Accounting
Standards  Board  is  currently  evaluating  certain  matters  relating  to  the
accounting for business combinations. Concentra is unable to predict the impact,
if any, that this review may have on the Company's acquisition strategy.

     Concentra 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 and to enter into management  agreements in selected  markets.
The  Company's  strategy  is to form these  joint  ventures  or enter into these
management   agreements  with   competitively-positioned   hospital   management
companies,  hospital  systems and other  healthcare  providers.  There can be no
assurances  that Concentra will continue to utilize joint ventures or management
agreements as part of its growth strategy,  that further suitable joint ventures
or  management  agreements  can be entered into or that such  existing or future
joint ventures or management relationships will be successful.


EFFECT OF AMORTIZATION ON RESULTS OF OPERATIONS

     Concentra  has had,  and will  continue  to have,  significant  charges for
depreciation and  amortization  expense related to the fixed assets and goodwill
and  other  intangibles  acquired,  or  to be  acquired,  in  its  acquisitions.
Consequently,  the Company expects that such  depreciation and amortization will
continue  to  have  an  impact  on  its  results  of  operations.   The  Company
periodically  reviews  whether  changes have  occurred,  either  specific to the
business or  generally  in the  industry,  which might  require  revision of the
remaining  estimated  useful  life of the  assigned  goodwill or render all or a
portion of the goodwill non-recoverable. In accordance with Financial Accounting
Standards No. 121,  "Accounting  for the  Impairment  of  Long-Lived  Assets and
Long-Lived  Assets to be Disposed of,"  impairments  are determined by comparing
undiscounted  estimated  future cash flows to the carrying  value of  long-lived
assets.  At December  31,  1998,  intangible  assets were  approximately  $280.4
million compared to total assets of $657.2 million and  stockholders'  equity of
$239.9 million.


MANAGEMENT OF GROWTH

     Concentra  has  experienced  rapid growth.  Continued  growth could place a
significant strain on the Company's management and other resources.  The Company
anticipates that continued growth, if any, will require it to


                                      15



<PAGE>


continue  to recruit,  hire,  train and retain a  substantial  number of new and
highly-skilled  administrative,   information  technology,  finance,  sales  and
marketing and support personnel.  Concentra's ability to compete effectively and
to manage  future  growth,  if any,  will  depend on its  ability to continue to
implement and improve operational,  financial and management information systems
on a timely  basis and to expand,  train,  motivate  and manage its work  force.
Should Concentra continue to experience rapid growth,  there can be no assurance
that the Company's personnel,  systems, procedures and controls will be adequate
to  support  the  Company's   operations  or  that  management  will  anticipate
adequately  all demands  that growth will place on the Company.  If  Concentra's
management is unable to manage growth effectively,  the quality of the Company's
products and its business,  operating  results and financial  condition could be
materially and adversely affected.


COMPETITION

     The market to provide healthcare services within the workers'  compensation
system is highly  fragmented and competitive.  Concentra's  primary  competitors
have typically been independent  physicians,  hospital emergency departments and
other urgent care providers.  The Company believes that, as integrated  networks
continue to be developed,  its healthcare services competitors will increasingly
consist of specialized provider groups.

     Concentra  faces managed care services  competition  from national  managed
care providers,  smaller independent  providers,  and insurance  companies.  The
Company believes that, as managed care techniques continue to gain acceptance in
the  workers'   compensation   marketplace,   the  Company's   competitors  will
increasingly  consist of nationally focused workers'  compensation  managed care
service  companies,  insurance  companies,  and other  significant  providers of
managed care products.  Legislative  reforms in some states permit  employers to
designate  health plans such as PPOs to cover workers'  compensation  claimants.
Because many health plans have the ability to manage  medical costs for workers'
compensation  claimants,  such  legislation  may  intensify  competition  in the
markets served by the Company.

     In the face of such  competition,  there can be no assurance that Concentra
will continue to maintain its existing performance or be successful with any new
products or in any new geographic markets it may enter.


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.  Concentra  believes  that  such  initiatives  will  continue  in  the
foreseeable future.  Aspects of certain of these reforms as proposed in the past
could, if adopted, adversely affect the Company.


RISKS INHERENT IN PROVISION OF MEDICAL SERVICES; POSSIBLE LITIGATION AND LEGAL
   LIABILITY

     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 medical  malpractice  claims.  Claims of this nature, if successful,
could result in substantial  damage awards against the Company and the Physician
Groups  that  could  exceed  the limits of any  applicable  insurance  coverage.
Concentra is  indemnified  under its  management  agreements  with the Physician
Groups from certain losses,  including medical malpractice and maintains medical
malpractice insurance.  However,  successful malpractice claims asserted against
the Physician  Groups or the Company could have a material adverse effect on the
Company's financial condition and profitability.

     Through  its  specialized   cost  containment  and  field  case  management
services,  Concentra makes  recommendations  concerning the  appropriateness  of
providers' proposed medical treatment of patients throughout the country, and as
a result the Company could be subject to claims arising from any adverse medical
consequences. The Company does not grant or deny claims for payment of benefits,
and the Company  does not believe that it engages in the practice of medicine or
the  delivery  of medical  services in the  provision  of its  specialized  cost
containment  and  field  case  management  services.  However,  there  can be no
assurance that Concentra will not be subject to claims or litigation  related to
the grant or denial of claims for payment of benefits  or  allegations  that the
Company engages in the practice of medicine or the delivery of medical  services
in this context.  In addition,  there can be no assurance  that the Company will
not be subject  to other  litigation  that may  adversely  affect the  Company's
business or results of  operations.  Concentra  maintains  errors and  omissions
insurance  and  such  other  lines  of  coverage  as the  Company  believes  are
reasonable in light of the Company's experience to date. There



                                       16



<PAGE>


can be no  assurance,  however,  that  such  insurance  will  be  sufficient  or
available at reasonable  cost to protect  Concentra from  liability  which might
adversely affect the Company's business or results of operations.


CORPORATE PRACTICE OF MEDICINE AND OTHER LAWS AND REGULATIONS

     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 physicians and  non-physicians.  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 Concentra's. The Company attempts to
structure all of its healthcare  services  operations to comply with  applicable
state statutes  regarding  medical  practice,  fee-splitting and similar issues.
However,  there can be no assurance  (i) that courts or  governmental  officials
with the power to  interpret  or  enforce  these laws and  regulations  will not
assert that Concentra is in violation of such laws and  regulations or (ii) that
future  interpretations  of such laws and regulations will not require Concentra
to modify the structure and organization of its business.

     Many  states,  including a number of those in which the  Company  transacts
business,  have licensing and other  regulatory  requirements  that apply to the
Company's  specialized  cost  containment  and field case  management  business.
Approximately  half of the states have enacted  laws that  require  licensing of
businesses that provide medical review  services,  such as Concentra's.  Some of
these laws apply to medical  review of care  covered by  workers'  compensation.
These  laws  typically   establish  minimum  standards  for   qualifications  of
personnel,  confidentiality,  internal  quality  control and dispute  resolution
procedures. These regulatory programs may result in increased costs of operation
for the Company,  which may have an adverse impact upon the Company's ability to
compete with other  available  alternatives  for  healthcare  cost  control.  In
addition,  new laws  regulating the operation of managed care provider  networks
have been  adopted by a number of states.  These laws may apply to managed  care
provider networks having contracts with the Company or to provider networks that
the Company has  organized  and may  organize in the future.  To the extent that
Concentra  is governed  by these  regulations,  it may be subject to  additional
licensing  requirements,   financial  oversight  and  procedural  standards  for
beneficiaries and providers.

     Regulation in the healthcare and workers' compensation fields is constantly
evolving. Concentra is unable to predict what additional government regulations,
if any,  affecting its business may be promulgated in the future.  The Company's
business may be adversely  affected by failure to comply with  existing laws and
regulations,  failure to obtain necessary  licenses and government  approvals or
failure to adapt to new or modified regulatory requirements.


FRAUD AND ABUSE AND ILLEGAL REMUNERATION LAWS

     The  Anti-Kickback  Statute prohibits the 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, 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 eleven  "designated  health services" (some of which are
provided by Physician Groups affiliated with Concentra).

     At least six of the states in which the  Company  conducts  its  healthcare
services business (Florida, California, Texas, Arizona, New Jersey and Maryland)
have  enacted  statutes  similar  in scope and  purpose  to the  Anti-  Kickback
Statute,  with applicability to services other than those covered by Medicare or
other  governmental  health  programs.  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. Even in states
which have not enacted  such  statutes,  the Company  believes  that  regulatory
authorities and state courts  interpreting these statutes may regard federal law
under the Anti-Kickback Statute and the Stark Amendments as persuasive.


                                       17



<PAGE>


     Concentra  believes that its arrangements  with the Physician Groups comply
with the Anti-Kickback  Statute, the Stark Amendments and applicable state laws.
However,   all  of  the  foregoing   laws  are  subject  to   modification   and
interpretation,  have not often been interpreted by appropriate authorities in a
manner  applicable  to the  Company's  business and are enforced by  authorities
vested with broad  discretion.  Concentra  has attempted to structure all of its
operations  so  that  they  comply  with  all   applicable   anti-kickback   and
anti-referral prohibitions.  Concentra also continually monitors developments in
this area. If these laws are  interpreted  in a manner  contrary to  Concentra's
interpretation or are reinterpreted or amended, or if new legislation is enacted
with respect to  healthcare  fraud and abuse,  illegal  remuneration  or similar
issues, the Company will seek to restructure any affected operations to maintain
compliance   with   applicable   law.  No  assurance  can  be  given  that  such
restructuring  will be possible,  or, if  possible,  will not  adversely  affect
Concentra's business or results of operations.


RELIANCE ON DATA PROCESSING AND LICENSED SOFTWARE

     Certain  aspects of Concentra's  business are dependent upon its ability to
store,  retrieve,  process and manage data and to maintain  and upgrade its data
processing  capabilities.  Interruption of data processing  capabilities for any
extended  length  of time,  loss of  stored  data,  programming  errors or other
computer problems could have a material adverse effect on the Company's business
and results of operations.

     Certain of the  software  Concentra  uses  within its  medical  bill review
operation is licensed from an independent  third-party software company pursuant
to a  non-exclusive  license  that may be  terminated  by either  party upon six
months  notice.   Although  the  Company  has  historically  maintained  a  good
relationship  with the  licensor,  there can be no assurance  that this software
license will not be terminated or that the licensor will be able to continue the
license on its existing terms. The Company is currently negotiating an extension
of this software license. Although management believes that alternative software
would be available if the existing  license were  terminated,  such  termination
could be  disruptive  and could have a material  adverse  effect on  Concentra's
business and results of operations.


INFORMATION SYSTEM UPGRADES AND YEAR 2000 COMPLIANCE

     The Year 2000  concern,  which is common to most  companies,  involves  the
inability  of  information  and  non-information  systems,   primarily  computer
software programs, to properly recognize and process date-sensitive  information
as the year 2000 approaches. System database modifications and/or implementation
modifications  will be required to enable such  information and  non-information
systems to  distinguish  between  20th and 21st  century  dates.  Concentra  has
completed a number of acquisitions in recent years, and the information  systems
of some of the  acquired  businesses  have not been  fully  integrated  with the
Company's information systems.

     Concentra  has formed a Year 2000 Program  Office to provide a  centralized
management  function  for the entire  Company  that will assist in  identifying,
addressing  and  monitoring  the Company's  Year 2000  readiness and  compliance
programs. The Year 2000 Program Office has organized teams in each business unit
of the Company to research Year 2000 compliance status and implement appropriate
solutions.  Concentra's  Year 2000  Program  includes  five phases -  awareness,
assessment,   remediation,   testing  and  implementation.   The  awareness  and
assessment  phases  are  substantially   complete  with  the  exception  of  the
assessment  phase of the Company's  information  systems  infrastructure  (i.e.,
desktops and other hardware) Year 2000 compliance.

     The Company's  Year 2000 Program  Office  engaged an outside  consultant to
assist in an  inventory  and  assessment  of Year 2000  affected  areas,  with a
primary focus on information  technology  systems,  third party software and key
suppliers and selected customers. This inventory and assessment was completed in
the fourth  quarter of 1998.  The Company's  Year 2000 Program Office engaged an
outside  consultant in the first quarter of 1999 to assist in an inventory,  and
assessment  and  remediation  efforts  of  the  Company's   information  systems
infrastructure Year 2000 compliance. The Company completed in the fourth quarter
of 1998 an internal  inventory  and  assessment  of  non-information  technology
systems (e.g., embedded systems contained in medical equipment).  Remediation or
replacement  of  noncompliant  Year 2000  medical  equipment  began in the first
quarter of 1999 and  Concentra  expects this effort to be completed by the third
quarter of 1999.

    The Year 2000 Program Office has established a protocol for soliciting Year
2000  compliance  information  from third  parties.  Concentra sent requests for
compliance  information  from all key  suppliers  and selected  customers in the
fourth  quarter of 1998 and first  quarter of 1999.  The  Company  continues  to
gather Year 2000  compliance  information  from third  parties  and  anticipates
receiving the majority of responses by the end of the second quarter of 1999. To
the extent  responses have not been  received,  the Year 2000 Program Office has
ranked the third parties by level of importance to the Company's  operations and
is following up with phone surveys,  additional  mailings and research of public
information issued by the third party (i.e., internet research). These responses
should  indicate  the extent to which  Concentra  is  vulnerable  to those third
parties' failure to remediate their own Year 2000 issues.

     The  Company's  identified  Year 2000  projects  overlap  with its  ongoing
investments in information  technology.  As such,  there are presently Year 2000
projects at the  assessment,  remediation,  testing and  implementation  phases.
Concentra believes that it has identified most "mission critical" issues and has
developed or is in the process of modifying  appropriate  action plans which may
include software upgrades, replacement of noncompliant components or referral of
problems related to third party-provided  software to the original supplier. The
Company has prepared its plans to have all "mission critical" projects Year 2000
compliant  by the end of the  fourth  quarter of 1999.  While some  non-critical
systems may not be addressed  until after December  1999,  the Company  believes
such systems will not disrupt the Company's operations in a material manner. Any
additional issues that may arise will be classified as either "mission critical"
or non-critical, and appropriate action plans will be developed and implemented.
Concentra  expects to have  formulated  any necessary  contingency  plans by the
third quarter of 1999.

     Concentra  currently estimates that the total cost of implementing its Year
2000  Program  will be between  $5,000,000  and  $10,000,000.  This  preliminary
estimate is based upon presently  available  information  and will be updated as
the Company finalizes its assessments and continues through  implementation.  In
particular,  the estimate may also need to be increased as the Company  receives
feedback from key suppliers and selected  customers and  formulates  contingency
plans,  if  required.  It is  expected  these  costs  will not be  significantly
different  from   Concentra's   current   planned   investment  for  information
technology,  and  therefore,  should not have a material  adverse  effect on the
Company's long-term results of operations,  liquidity or consolidated  financial
position. However, until the information systems infrastructure assessment phase
is  completed  in the second  quarter of 1999,  the Company is  uncertain if its
present plans and resources will be sufficient to ensure Year 2000 compliance of
all "mission critical" projects by January 1, 2000.

     Although  Concentra does not anticipate any disruption in its operations or
financial reporting as a result of system upgrades or system integrations, there
can be no  assurance  that  such  disruption  will not  occur or that  Year 2000
compliance  of the Company's  information  and  non-information  systems will be
realized.  If the Company does not identify and remediate Year 2000 issues prior
to  January  1, 2000,  its  operations  could be  disrupted  which  could have a
material  adverse  effect on the  Company's  business  or  operating  results or
financial condition.  In addition,  the Company places a high degree of reliance
on computer  systems of third parties,  such as customers,  trade  suppliers and
computer  hardware and commercial  software  suppliers.  Although the Company is
assessing the readiness of these third  parties,  there can be no guarantee that
the  failure  of these  third  parties  to modify  their  systems  in advance of
December 31, 1999 would not have a material  adverse  effect on the Company.  In
addition,  Concentra's operations could be disrupted if the companies with which
Concentra  does  business do not  identify  and correct any Year 2000 issues and
their failure adversely affects their ability to do business with Concentra.  If
all Year 2000 issues are not  identified  and all action plans are not completed
and contingency plans become necessary, Concentra may not be Year 2000 compliant
which could have a material adverse effect on the Company's long-term results of
operations,  liquidity,  or  consolidated  financial  position.  The  amount  of
potential liability and lost revenue has not been estimated.


VOLATILITY OF STOCK PRICE

     The market price of  Concentra's  Common Stock has been volatile and may be
volatile  in the  future.  Future  developments  concerning  the  Company or its
competitors,   including  developments  related  to  governmental   regulations,
acquisitions,  operating results,  the healthcare industry generally and general
market and  economic  conditions,  may have a  significant  impact on the market
price of Concentra's Common Stock.

DIVIDEND POLICY AND RESTRICTIONS

     Concentra  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.  Concentra's revolving credit agreement
with its senior lenders  prohibits the Company from paying  dividends and making
other distributions on its Common Stock.


ANTI-TAKEOVER PROVISIONS

     Certain provisions of Concentra'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,
Concentra's  Certificate  of  Incorporation  provides  for a staggered  Board of
Directors. The Certificate of Incorporation also 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.
Concentra  has also  adopted  a Rights  Agreement,  which is  intended  to deter
certain takeover practices or takeover bids.

     In connection with the Merger,  effective March 2, 1999,  Concentra amended
its Rights Agreement.  The amendment  provides,  among other things, that Yankee
and its  affiliates  will not be deemed  an  Acquiring  Person  (as such term is
defined  in  the  Rights   Agreement)  and  the  Rights  Agreement  will  expire
immediately prior to the effective time of the Merger




ITEM 2. PROPERTIES 

     The   Company's   principal   corporate   office  is   located  in  Boston,
Massachusetts.  The Company  leases the 11,000 square feet of space in this site
pursuant  to a lease  agreement  expiring  in 2003.  Except for 13  occupational
medical  centers  owned by the  Company,  the Company  leases all of its offices
located in 49  states,  the  District  of  Columbia  and  Canada.  Twelve of the
Company's  offices  are leased  from  Colonial  Realty  Trust,  of which Lois E.
Silverman, a director of the Company, is a trustee and beneficiary.  The Company
believes  that its  facilities  are  adequate  for its  current  needs  and that
suitable additional space will be available as required.


ITEM 3. LEGAL PROCEEDINGS

     As of the date hereof,  Concentra is aware of three lawsuits that have been
filed by alleged  stockholders  of Concentra  relating to the Merger.  All three
lawsuits were filed in the Chancery Court for New Castle County,  Delaware. Each
of the lawsuits names  Concentra,  its directors and Yankee as  defendants.  The
plaintiff  in each  lawsuit  seeks to  represent a putative  class of all public
holders of Concentra common stock. The lawsuits allege, among other things, that
the  directors of  Concentra  breached  their  fiduciary  duties to  Concentra's
stockholders  by approving the Merger.  The lawsuits  seek,  among other things,
preliminary  and permanent  injunctive  relief  prohibiting  consummation of the
Merger, unspecified damages, attorneys' fees and other relief. Concentra expects
that these  lawsuits  will be  consolidated  into a single  action.  The Company
intends to contest these lawsuits vigorously.

     The Company is party to certain other claims and litigation in the ordinary
course of  business.  Other than as described in the  preceding  paragraph,  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.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     During the fourth  quarter of 1998,  no matter was  submitted  to a vote of
security holders.

OVERVIEW

     On August 29, 1997, Concentra,  a Delaware  corporation,  was formed by the
merger (the "1997 Merger") of CRA Managed Care,  Inc.  ("CRA") and  OccuSystems,
Inc.  ("OccuSystems").  The 1997 Merger was a tax-free  stock for stock exchange
accounted for as a pooling of interests.

     Concentra  Health  Services,   Inc.  ("Health   Services"),   an  operating
subsidiary  of  Concentra,   which  was  formerly  OccuSystems,   Inc.,  manages
occupational   healthcare  centers  at  which  it  provides  support  personnel,
marketing,  information  systems  and  management  services  to  its  affiliated
physicians. Health Services owns all of the operating assets of the occupational
healthcare centers, including leasehold interests and medical equipment.  Health
Services   generates  its  net  patient  service  revenues  primarily  from  the
diagnosis,  treatment and management of work-related  injuries and illnesses and
from  other  occupational  healthcare  services,  such  as  employment-  related
physical examinations, drug and alcohol testing, functional capacity testing and
other related  programs.  For the years ended December 31, 1996,  1997 and 1998,
Health  Services  derived  64.0%,  63.5% and 63.1% of its net revenues  from the
treatment of work-related injuries and illnesses,  respectively and 36.0%, 36.5%
and  36.9%  of its  net  revenues  from  non-injury  related  medical  services,
respectively.

     Physician and physical therapy services are provided at the Health Services
centers  under  management  agreements  with the  Physician  Groups,  which  are
organized  professional  corporations that hire licensed physicians and physical
therapists to provide medical  services to the centers'  patients.  Since Health
Services effectively controls the Physician Groups,  Health Services' results of
operations  reflect the revenues generated by the Physician Groups and the costs
associated with the delivery of their services.  The financial statements of the
Physician Groups are consolidated because Health Services has unilateral control
over the assets and operations of the Physician Groups and  notwithstanding  the
lack of technical majority ownership, consolidation of the Physician Groups with
Health  Services is  necessary  to present  fairly the  financial  position  and
results  of   operations   of  Health   Services  due  to  the  existence  of  a
parent-subsidiary  relationship  by means  other than  record  ownership  of the
Physician Group's voting stock. The shareholders of the Physician Groups are the
physician leaders of Health Services, and are employed by Health Services or one
of its  wholly-owned  subsidiaries.  Through  a  shareholder  agreement,  Health
Services restricts any transfer of Physician Group ownership without its consent
and can  require the holder of such  shares to  transfer  ownership  to a Health
Services  designee  upon the  occurrence  of certain  events,  including but not
limited to the  cessation  of  employment.  Control of the  Physician  Groups is
perpetual due to the nature of the  relationship  and the management  agreements
between the  entities.  The employed  physicians  do not control fee  schedules,
payor contracts or employment  decisions regarding  personnel.  The risk of loss
for billed  services  provided by the Physician  Groups resides  ultimately with
Health  Services as  Concentra  is required to provide  financial  support on an
as-needed basis.

     Concentra  Managed  Care  Services,  Inc.  ("Managed  Care  Services"),  an
operating  subsidiary of Concentra  which was formerly CRA Managed  Care,  Inc.,
provides specialized cost containment and field case management

                                       22

services.   Specialized  cost  containment  includes  first  report  of  injury,
utilization management  (precertification and concurrent review),  retrospective
medical bill review, telephonic case management,  PPO network access, IMEs, peer
reviews and hospital bill auditing services that are designed to reduce the cost
of workers'  compensation  claims,  automobile  accident injury claims and group
health claims.  On February 24, 1998, the Company merged with Preferred  Payment
Systems,  Inc. ("PPS") in a  pooling-of-interests  transaction and significantly
expanded its  presence in the  out-of-network  group health bill review  market.
PPS,  now  operating  as CPS,  is a  nationwide  provider  of  specialized  cost
containment and outsourcing services for healthcare payors. In the first quarter
of 1998, the Company  recorded a non-recurring  charge of $12,600,000  primarily
associated  with the  merger  of PPS.  Managed  Care  Services  has  experienced
significant growth in its specialized cost containment services by virtue of the
following acquisitions: (1) FOCUS HealthCare Management, Inc. ("FOCUS") on April
2, 1996, (2) Prompt Associates,  Inc.  ("PROMPT") on October 29, 1996, (3) First
Notice Systems,  Inc. ("FNS"),  on June 4, 1997, (4) About Health,  Inc. ("ABOUT
HEALTH") by PPS in a two-step transaction on August 1, 1997 and October 31, 1997
and (5) other smaller acquisitions. Managed Care Services currently derives most
of its revenues on a fee-for-service basis.

     Field case management  services  involve working on a one-on-one basis with
injured  employees and their various  health care  professionals,  employers and
insurance  company  adjusters to assist in maximizing  medical  improvement and,
where appropriate,  to expedite the return to work. Managed Care Services' field
case  management  revenue growth has resulted from both local market share gains
and geographic  office  expansion;  however,  field case management gross profit
margins  deteriorated in the second half of 1998 prompting a  reorganization  in
the fourth  quarter  of 1998 to improve  efficiency.  As a result,  the  Company
recorded a  non-recurring  charge of $20,514,000  primarily  associated with the
reorganization  of its Managed  Care  Services  division  to improve  efficiency
through facility  consolidations and related headcount reductions,  to recognize
an impairment loss on the intangible  related to an acquired  contract and costs
associated  with  settling  claims  on other  expired  contracts.  Managed  Care
Services  believes  that the current  size of its field case  management  office
network  is  sufficient  to serve the needs of its  nationwide  customers.  As a
result,  Managed  Care  Services  anticipates  opening only a few new field case
management  offices per year if client needs in selected regions require it. The
Company  would,  however,  continue  to examine  the  possibility  of  acquiring
additional  field  case  management  offices  or  businesses  if an  appropriate
strategic opportunity arose.

management revenues increased 21.0% in 1998 to $167,841,000 from $138,723,000 in
1997.

     The  Health  Services  revenue  growth  resulted  from the  acquisition  of
practices  (including the acquisition of 16 occupational medical centers and the
management of an additional  four medical centers from Vencor,  Inc.  ("VMC") in
the fourth  quarter of 1997),  an increase  in  business  in  existing  markets,
development  of sites in new markets,  as well as an increase in consulting  and
other ancillary  services.  The specialized cost  containment  revenue growth is
largely  attributable  to  the  growth  of  PPS  (including  the  impact  of its
acquisition  of ABOUT HEALTH in August 1997),  the  acquisition of FNS and other
immaterial acquisitions,  as well as revenue increases attributable to growth in
retrospective medical bill review,  telephonic case management and claims review
services in existing service locations. The field case management revenue growth
is  primarily  due to the  business  generated  from two field  case  management
acquisitions and continued growth in revenues from existing service locations.

COST OF SERVICES

     Total  cost of  services  increased  26.0%  in 1998  to  $474,102,000  from
$376,250,000 in 1997. Health Services' cost of services  increased 29.6% in 1998
to $205,986,000  from $158,987,000 in 1997, while Managed Care Services' cost of
services increased 23.4% in 1998 to $268,116,000 from $217,263,000 in 1997.

     Total gross profit margins decreased  slightly to 23.1% in 1998 compared to
23.8% in 1997.  Health Services' gross profit margins decreased to 22.3% in 1998
compared to 25.1% in 1997,  while Managed Care  Services'  gross profit  margins
increased to 23.7% in 1998 compared to 22.9% in 1997.

     Health Services' gross profit margins decreased primarily as a result of an
acceleration  in the roll-out of patient  tracking and billing  systems into the
medical centers,  increased spending on marketing and facility  improvements and
the impact of lower gross profit  margins from practices  recently  acquired and
developed.  Historically,  as  certain  functions  are  consolidated  and  other
staff-related  changes occur,  coupled with increased patient volume,  the gross
profit margins of acquired or developed practices have tended to improve.

     Managed  Care  Services  has  seen  improvement  in  gross  profit  margins
primarily  resulting  from a shift in its revenue mix towards  specialized  cost
containment  services,  including the services  provided by PPS  (including  its
acquisition of ABOUT HEALTH) and FNS, which  historically  have had higher gross
profit margins than revenues  derived from field case  management.  Although the
gross profit margins improved slightly in 1998, they were negatively affected by
a decrease in provider  bill review gross profit  margins and a slow down in the
growth of field case management revenues and resulting gross profit margins. The
provider bill review gross profit margins decrease was due primarily to start-up
costs,  pricing  concessions  on new  customers  and an increase in the level of
uncollectable accounts receivable charges.

GENERAL AND ADMINISTRATIVE EXPENSES

     General and administrative  expenses increased 13.8% in 1998 to $45,530,000
from  $40,008,000  in 1997, or 7.4% and 8.1% as a percentage of revenue for 1998
and 1997,  respectively.  The increase in general and administrative expenses in
1998 was due primarily to the continued  investment in the Information  Services
and Technology Group and in accounting and administrative personnel.

AMORTIZATION OF INTANGIBLES

     Amortization  of  intangibles  increased  37.4% in 1998 to $8,167,000  from
$5,945,000  in 1997,  or 1.3% and 1.2% as a percentage  of revenues for 1998 and
1997,  respectively.  This  increase  is the  result  of  amortizing  additional
intangible  assets such as goodwill,  customer  lists and  assembled  workforces
primarily  associated  with the  purchases of FNS,  ABOUT HEALTH by PPS, VMC and
various smaller acquisitions by Health Services.

NON-RECURRING CHARGE

     The Company recorded non-recurring charges for the years ended December 31,
1997 and 1998 of $38,625,000 and $33,114,000, respectively.


                                       24



<PAGE>

         In the first  quarter of 1998,  the  Company  recorded a  non-recurring
charge  of  $12,600,000  primarily  associated  with  the  merger  of  PPS.  The
utilization  of  this  charge  through  December  31,  1998,  was  approximately
$5,136,000 for  professional  fees and services,  $2,355,000 in costs associated
with personnel  reductions,  $746,000 in facility  consolidations  and closings,
$1,627,000  associated  with the  write-off  of deferred  financing  fees on PPS
indebtedness  retired and $1,264,000 of other  non-recurring  costs. At December
31, 1998, approximately $1,472,000 of the non-recurring charge remains primarily
related to remaining facility lease obligations.

     In the fourth quarter of 1998, the Company recorded a non-recurring  charge
of $20,514,000  primarily associated with the reorganization of its Managed Care
Services  division to improve  efficiency  through facility  consolidations  and
related headcount reductions,  to recognize an impairment loss on the intangible
related to an acquired  contract and costs  associated  with settling  claims on
other expired  contracts.  The  utilization of this charge through  December 31,
1998 was  approximately  $7,416,000 in charges  related to the recognition of an
impairment loss on the intangible related to an acquired contract, $2,490,000 in
costs   associated   with  personnel   reductions  and  $1,140,000  in  facility
consolidations.   At  December  31,  1998,   approximately   $9,468,000  of  the
non-recurring  charge  remains  primarily  related to remaining  facility  lease
obligations  and  costs   associated  with  settling  claims  or  other  expired
contracts.

     In the third quarter of 1997, the Company  recorded a non-recurring  charge
of  $38,625,000  associated  with the  merger  of CRA  Managed  Care,  Inc.  and
OccuSystems,  Inc. The utilization of this charge through December 31, 1998, was
approximately  $11,569,000 for  professional  fees and services,  $16,216,000 in
costs  associated with personnel  reductions and the  consolidation of CRA's and
OccuSystems'  employee  benefits,  $5,945,000  in  facility  consolidations  and
closings, $2,541,000 for the write-off of start-up costs and $2,354,000 of other
charges.


INTEREST EXPENSE

     Interest  expense   increased   $5,354,000  in  1998  to  $18,021,000  from
$12,667,000 in 1997 due primarily to increased outstanding  borrowings under the
credit  facilities to finance  acquisitions  and the issuance of $230,000,000 in
4.5% Convertible  Subordinated Notes in March and April 1998 partially offset by
the repayment of borrowings under the Senior Credit Facility and debt assumed in
the merger with PPS.


INTEREST INCOME

     Interest income increased  $2,362,000 in 1998 to $4,659,000 from $2,297,000
in 1997 due  primarily to the  investment  of excess cash as a result of the net
proceeds of  $223,589,000  from the issuance the 4.5%  Convertible  Subordinated
Notes after the payment of approximately  $122,000,000 of outstanding borrowings
under the Senior  Credit  Facility,  debt assumed in the merger with PPS and the
payment to PPS dissenting shareholders.


OTHER EXPENSE, NET

     Other expense,  net decreased  $908,000 in 1998 to $711,000 from $1,619,000
in 1997 primarily as a result of PPS' 1997 minority interest expense of $556,000
related to the two-step acquisition of ABOUT HEALTH and the 1997 amortization of
start-up costs of $315,000  recorded prior to the write-off of start-up costs in
the third quarter of 1997.


PROVISION FOR INCOME TAXES

     The Company's  provision for income taxes in 1998 and 1997 was  $19,308,000
and $11,062,000,  respectively.  On a pro forma basis,  giving effect to the PPS
transaction,  the  Company's  provision  for income taxes in 1998 and 1997 would
have been  $19,308,000  and  $13,873,000,  respectively,  resulting in pro forma
effective tax rates of 46.2% and 65.9%, respectively.  Excluding the tax effects
of the non-recurring  charges in the third quarter of 1997, the first quarter of
1998 and the fourth quarter of 1998, the pro forma effective tax rate would have
been 41.0% for 1998 and 39.3% for 1997.  The Company  expects to provide for its
taxes at an effective tax rate of approximately 41% to 42% for 1999.


RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1997 AND 1996


REVENUES

     Total revenues increased 32.5% in 1997 to $493,879,000 from $372,683,000 in
1996.  Health Services'  revenues  increased 24.8% in 1997 to $212,237,000  from
$170,035,000 in 1996. Managed Care Services' revenues


                                       25



<PAGE>

increased  39.0%  in  1997  to  $281,642,000   from  $202,648,000  in  1996,  as
specialized  cost containment  revenues  increased 70.6% in 1997 to $142,919,000
from $83,784,000 in 1996 and field case management  revenues  increased 16.7% in
1997 to $138,723,000 from $118,864,000 in 1996.

     The  Health  Services  revenue  growth  resulted  from the  acquisition  of
practices  (including the acquisition of 16 occupational medical centers and the
management of an additional  four medical centers from VMC in the fourth quarter
of 1997),  development  of sites in new  markets,  an  increase  in  business in
existing  markets,  as well as an increase  in  consulting  and other  ancillary
services.   The  specialized   cost   containment   revenue  growth  is  largely
attributable to the acquisitions of FOCUS, PROMPT, FNS and ABOUT HEALTH, as well
as  revenue  increases  attributable  to growth in  retrospective  medical  bill
review,  telephonic  case  management  and claims  review  services  in existing
service locations and the expansion into additional service locations. The field
case  management  revenue  growth is  primarily  due to growth in revenues  from
existing service locations, and the opening of 13 offices during 1996 and 1997.


COST OF SERVICES

     Total  cost of  services  increased  29.8%  in 1997  to  $376,250,000  from
$289,928,000 in 1996. Health Services' cost of services  increased 21.6% in 1997
to $158,987,000  from $130,754,000 in 1996, while Managed Care Services' cost of
services increased 36.5% in 1997 to $217,263,000 from $159,174,000 in 1996.

Total gross profit margins increased to 23.8% in 1997 compared to 22.2% in 1996.
Health  Services'  gross profit  margins  increased to 25.1% in 1997 compared to
23.1% in 1996,  while Managed Care Services'  gross profit margins  increased to
22.9% in 1997 compared to 21.5% in 1996.

     Health  Services'  gross  profit  margin   improvement  has  resulted  from
increased  efficiencies and productivity.  As certain functions are consolidated
and other  staff-related  changes occur,  coupled with increased patient volume,
the margins of acquired or developed  practices have tended to improve.  Managed
Care Services has seen  improvement in gross margin  primarily  resulting from a
shift  in  its  revenue  mix  towards  specialized  cost  containment  services,
including the services provided by FOCUS,  PROMPT,  FNS and ABOUT HEALTH,  which
historically  have had higher gross profit  margins than  revenues  derived from
field case management.


GENERAL AND ADMINISTRATIVE EXPENSES

     General and administrative  expenses increased 20.7% in 1997 to $40,008,000
from  $33,155,000  in 1996, or 8.1% and 8.9% as a percentage of revenue for 1997
and 1996,  respectively.  The increase in general and administrative expenses in
1997  was  due  primarily  to  expenses  associated  with  acquisitions  and the
continued investment in the Information Services and Technology Group.


AMORTIZATION OF INTANGIBLES

     Amortization  of  intangibles  increased  72.7% in 1997 to $5,945,000  from
$3,442,000  in 1996,  or 1.2% and 0.9% as a percentage  of revenues for 1997 and
1996,  respectively.  This  increase  is the  result  of  amortizing  additional
intangible  assets such as goodwill,  customer  lists and  assembled  workforces
primarily  associated with the purchase of FOCUS,  PROMPT,  FNS, ABOUT HEALTH by
PPS, VMC and other smaller acquisitions.


NON-RECURRING CHARGE

     The Company recorded a non-recurring charge of $38,625,000  associated with
the 1997  Merger.  The  charges  incurred  were  approximately  $11,569,000  for
professional  fees and services,  $16,216,000 in costs associated with personnel
reductions and the  consolidation of CRA's and OccuSystems'  employee  benefits,
$5,945,000 in facility consolidations and closings, $2,541,000 for the write-off
of  start-up  costs and  $2,354,000  of other  charges.  At December  31,  1997,
approximately  $7,527,000 of the non-recurring  charge remains primarily related
to personnel related charges and facility consolidations and closings.


INTEREST EXPENSE

     Interest  expense   increased   $8,926,000  in  1997  to  $12,667,000  from
$3,741,000  in  1996  due  primarily  to  the  issuance  of  $97,750,000  of  6%
Convertible   Subordinated   Notes  in  December   1996,  the  issuance  of  PPS
indebtedness  in  August  1996  and to  increased  outstanding  credit  facility
borrowings used to finance acquisitions.


                                       26



<PAGE>

INTEREST INCOME

     Interest income increased $1,438,000 in 1997 to $2,297,000 from $859,000 in
1996 due primarily to the  investment of excess cash generated from the issuance
of the 6%  Convertible  Subordinated  Notes  until the funds  were  utilized  to
finance certain acquisitions.


OTHER EXPENSE, NET

     Other expense,  net increased  $783,000 in 1997 to $1,619,000 from $836,000
in 1996 primarily due to minority interests.


PROVISION FOR INCOME TAXES

     The Company's  provision for income taxes in 1997 and 1996 was  $11,062,000
and $13,437,000,  respectively.  On a pro forma basis,  giving effect to the PPS
transaction,  the  Company's  provision  for income taxes in 1997 and 1996 would
have been  $13,873,000  and  $16,167,000,  respectively,  resulting in pro forma
effective tax rates of 65.9% and 39.0%, respectively.  Excluding the tax effects
of the  non-recurring  charge,  the pro forma effective tax rate would have been
39.3% for 1997.


SEASONALITY

     The  Company's  business is seasonal in nature.  Health  Services'  patient
visits at its  medical  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-placement  physical  examinations  and  drug and  alcohol  tests
conducted at the medical  centers  during that quarter.  Managed Care  Services'
field case management revenues have historically been flat in the fourth quarter
compared  to the third  quarter  due to the impact of  vacations  and  holidays.
Although the Company's  revenue  growth may obscure the effect of seasonality in
the Company's financial results, the first and fourth quarters generally reflect
lower revenues when compared to the Company's second and third quarters.


INFORMATION SYSTEMS - YEAR 2000

     The Year 2000  concern,  which is common to most  companies,  concerns  the
inability  of  information  and  non-information  systems,   primarily  computer
software programs,  to properly recognize and process date sensitive information
as the Year 2000 approaches. System database modifications and/or implementation
modifications  will be required to enable such  information and  non-information
systems to  distinguish  between  21st and 20th century  dates.  The Company has
completed a number of acquisitions in recent years, and the information  systems
of some of the  acquired  operations  have not been  fully  integrated  with the
Company's information systems.

     The Company has formed a Year 2000 Program  Office to provide a centralized
management function for the entire organization that will assist in identifying,
addressing  and  monitoring  the Company's  Year 2000  readiness and  compliance
programs.  The Year 2000 Program Office has organized  teams at each division to
research Year 2000 compliance  status and implement the  appropriate  solutions.
The Company's  Year 2000 Program  includes five phases - awareness,  assessment,
remediation, testing and implementation. The awareness and assessment phases are
substantially  complete  with  the  exception  of the  assessment  phase  of the
Company's information systems infrastructure (i.e., desktops and other hardware)
Year 2000 compliance.

     The Company's  Year 2000 Program  Office  engaged an outside  consultant to
assist in an  inventory  and  assessment  of Year 2000  affected  areas,  with a
primary focus on information  technology  systems,  third party software and key
suppliers and selected customers. This inventory and assessment was completed in
the fourth  quarter of 1998.  The Company's  Year 2000 Program Office engaged an
outside  consultant  in the first  quarter  of 1999 to  assist in an  inventory,
assessment  and  remediation  efforts  of  the  Company's   information  systems
infrastructure Year 2000 compliance. The Company completed in the fourth quarter
of 1998 an internal  inventory  and  assessment  of  non-information  technology
systems (e.g. embedded systems contained in medical  equipment).  Remediation or
replacement  of  noncompliant  Year 2000  medical  equipment  began in the first
quarter of 1999 and is expected to be completed by the third quarter of 1999.

     The Year 2000 Program Office has established a protocol for soliciting Year
2000  compliance  information  from third  parties and requests  for  compliance
information from all key suppliers and selected customers were


                                       27



<PAGE>

sent in the fourth  quarter of 1998 and the first  quarter of 1999.  The Company
continues  to gather Year 2000  compliance  information  from third  parties and
anticipates receiving the majority of responses by the end of the second quarter
of 1999. To the extent  responses have not been received,  the Year 2000 Program
Office has ranked the third  parties  by level of  importance  to the  Company's
operations  and is  following  up with phone  surveys,  additional  mailings and
research of public information issued by the third-party (i.e., "web research").
These responses should indicate the extent to which the Company is vulnerable to
those third parties' failure to remediate their own Year 2000 issues.

     The  Company's  identified  Year 2000  projects  overlap  with its  ongoing
investments in information  technology,  as such,  there are presently Year 2000
projects at the assessment,  remediation, testing and implementation phases. The
Company  believes that it has identified most "mission  critical" issues and has
developed or is in the process of modifying  appropriate  action plans which may
include software upgrades, replacement of noncompliant components or referral of
problems related to third party-provided  software to the original supplier. The
Company has prepared its plans to have all "mission critical" projects Year 2000
compliant  by the end of the  fourth  quarter of 1999.  While some  non-critical
systems may not be addressed  until after December  1999,  the Company  believes
such systems will not disrupt the Company's operations in a material manner. Any
additional issues that may arise will be classified as either "mission critical"
or non-critical, and appropriate action plans will be developed and implemented.
The Company expects to have formulated any contingency plans deemed necessary by
the third quarter of 1999.

     The Company  currently  estimates that the total cost of  implementing  its
Year 2000 Program will be between  $5,000,000 and $10,000,000.  This preliminary
estimate is based upon presently  available  information  and will be updated as
the Company finalizes its assessments and continues through  implementation.  In
particular,  the estimate may also need to be increased as the Company  receives
feedback from key suppliers and selected  customers and  formulates  contingency
plans,  if  required.  It is  expected  these  costs  will not be  significantly
different  from  the  Company's  current  planned   investment  for  information
technology,  and  therefore,  should not have a material  adverse  effect on the
Company's long-term results of operations,  liquidity or consolidated  financial
position. However, until the information systems infrastructure assessment phase
is  completed  in the second  quarter of 1999,  the Company is  uncertain if its
present plans and resources will be sufficient to ensure Year 2000 compliance of
all "mission  critical"  projects by January 1, 2000. The Company's  capital and
noncapital  investment  in the  Information  Services and  Technology  Group was
approximately  $32,000,000 in 1998 and expected to be approximately  $50,000,000
in 1999. Of this  investment,  the Company's Year 2000 Program  Office  incurred
expenses of approximately  $300,000 in fiscal 1998 primarily associated with the
engagement of an outside  consultant to assist in an inventory and assessment of
Year 2000 affected areas.

     Although the Company does not  anticipate  any disruption in its operations
or financial  reporting as a result of system  upgrades or system  integrations,
there  can be no  assurance  that  such  disruption  will not  occur or that the
desired benefits from the Year 2000 compliance of the Company's  information and
non-information  systems will be realized.  If the Company does not identify and
remediate  Year 2000 issues prior to January 1, 2000,  its  operations  could be
disrupted which could have a material  adverse effect on the Company's  business
or operating results or financial condition.  In addition,  the Company places a
high degree of reliance on computer systems of third parties, such as customers,
trade  suppliers  and  computer  hardware  and  commercial  software  suppliers.
Although the Company is assessing  the readiness of these third  parties,  there
can be no  guarantee  that the  failure of these third  parties to modify  their
systems in advance of December 31, 1999 would not have a material adverse effect
on the Company. In addition,  the Company's operations could be disrupted if the
companies  with which the Company does  business do not identify and correct any
Year 2000 issues and such failure adversely affects their ability to do business
with the  Company.  If all Year 2000  issues are not  identified  and all action
plans are not completed and contingency plans become necessary,  the Company may
not be Year 2000  compliant  which could have a material  adverse  effect on the
Company's long-term results of operations,  liquidity, or consolidated financial
position.  The  amount of  potential  liability  and lost  revenue  has not been
estimated.


LIQUIDITY AND CAPITAL RESOURCES

Cash flows generated from (used for) operations were $37,895,000, ($262,000) and
$15,595,000 for the years ended December 31, 1998, 1997 and 1996,  respectively.
During  1998,  working  capital used  $10,307,000  of cash  primarily  due to an
increase in accounts receivable of $19,993,000,  offset by a decrease in prepaid
expenses and income  taxes of  $1,421,000  and an increase in accounts  payable,
accrued expenses and income 


                                       28



<PAGE>

taxes of $8,265,000.  Accounts  receivable  increased primarily due to continued
revenue  growth,  while  accounts  payable,  accrued  expenses  and income taxes
increased due to the timing of payments and the remaining  obligations  relating
to the first quarter and fourth quarter of 1998 non-recurring charges.

     The  Company   utilized  net  cash  of  $18,070,000   in  connection   with
acquisitions,  $15,523,000 to purchase marketable  securities and $34,395,000 of
cash to purchase  property and equipment  during 1998, the majority of which was
spent on new computer hardware and software technology.

     Cash  flows  provided  by  financing  activities  of  $121,555,000  was due
primarily  to the  issuance of  $230,000,000  in 4.5%  Convertible  Subordinated
Notes,  $223,589,000,  net of deferred  finance  fees. A portion of the proceeds
from the issuance of the 4.5% Convertible  Subordinated  Notes was used to repay
borrowings  under the Senior Credit  Facility,  repay debt assumed in the merger
with PPS, and for the payment of $15,047,000 to PPS dissenting shareholders. Net
proceeds  from the issuance of Common Stock under  employee  stock  purchase and
option plans and the related tax benefit was $14,403,000.

         The Company  believes  that its current  cash  balances,  the cash flow
generated  from  operations and its borrowing  capacity  under the  $100,000,000
Senior  Credit  Facility,  if needed,  will be  sufficient to fund the Company's
working   capital,   medical  center   acquisitions   and  capital   expenditure
requirements  for at least the next  twelve  months.  As a result of the  fourth
quarter  1998  non-recurring  charge,  the  Company was not in  compliance  with
certain leverage ratio covenants under the  $100,000,000  Senior Credit Facility
in the  fourth  quarter  of  1998  and the  Company  expects  it will  not be in
compliance  with  those  covenants  in the first  quarter of 1999.  The  Company
received a waiver on all financial  covenants through the first quarter of 1999.
The Company does not have any  borrowings  outstanding  under the Senior  Credit
Facility  and does not  anticipate  the need to borrow  under the Senior  Credit
Facility for the next twelve months.

     The Company's  long-term  liquidity  needs  consist of working  capital and
capital expenditure requirements, the funding of any future acquisitions and the
repayment of the 6% Convertible  Subordinated Notes in 2001 and 4.5% Convertible
Subordinated  Notes  in  2003.  The  Company  intends  to fund  these  long-term
liquidity needs from the cash generated from  operations,  available  borrowings
under the Senior  Credit  Facility  and,  if  necessary,  future  debt or equity
financing.  There can be no assurance  that any future debt or equity  financing
will be available on terms favorable to the Company.


SUBSEQUENT EVENTS

     On March 2, 1999,  Concentra  entered into a definitive  agreement to merge
(the "Merger") with Yankee Acquisition Corp. ("Yankee"), a corporation formed by
Welsh,  Carson,  Anderson & Stowe ("WCAS"),  a 14.8% stockholder of the Company.
Concentra's Board of Directors  unanimously  approved the transaction based upon
the recommendation of its special committee of the Board of Directors, which was
formed on October  29, 1998 to evaluate  strategic  alternatives  in response to
several unsolicited  expressions of interest regarding the possible  acquisition
of some or all of the  Company's  Common  Stock.  On March 24,  1999,  Concentra
entered  into an Amended and Restated  Agreement  and Plan of Merger with Yankee
(the "Amended  Merger  Agreement").  Pursuant to the Amended  Merger  Agreement,
Yankee  will  acquire  approximately  93% and funds  managed  by Ferrer  Freeman
Thompson & Co. ("FFT") will acquire  approximately 7% of the post-merger  shares
of common stock of the Company for $16.50 per share.  As a result of the Merger,
each  outstanding  share of Concentra  Common  Stock will be converted  into the
right to receive $16.50 in cash.

     In connection with the Merger,  effective March 2, 1999,  Concentra amended
its Rights Agreement.  The amendment  provides,  among other things, that Yankee
and its  affiliates  will not be deemed  an  Acquiring  Person  (as such term is
defined  in the Rights  Agreement)  and that the Rights  Agreement  will  expire
immediately prior to the effective time of the Merger.

     The transaction is valued at  approximately  $1,100,000,000,  including the
refinancing of $327,750,000 of the 6% and 4.5%  Convertible  Subordinated  Notes
which  contain  change in control  provisions  in the  related  indentures.  The
transaction  is  structured  to be accounted  for as a  recapitalization  and is
expected to be completed late in the second quarter of 1999. The  transaction is
conditioned upon, among other things, approval of the shareholders of Concentra,
receipt of financing and certain regulatory approvals.

     To finance the acquisition of the Company,  WCAS will invest  approximately
$350,000,000 in equity financing, including the value of shares already owned by
WCAS, and up to  $110,000,000 in subordinated  indebtedness.  Additionally,  FFT
will  invest  approximately  $30,000,000  in  equity.  WCAS  has  also  received
commitments  from various lenders to provide Yankee with  $190,000,000 in senior
subordinated notes, a 

                                       29



<PAGE>

$375,000,000  term loan and a $100,000,000  revolving credit facility to replace
the Company's existing Senior Credit Facility.  Additionally,  Yankee would also
utilize  the  Company's  excess  cash on hand at the time of the  merger to help
finance the purchase of the Common  Stock.  Subsequent to the exchange of shares
for cash,  Yankee would merge with Concentra  Managed Care,  Inc. with Concentra
Managed Care, Inc. surviving.

     As of March 26, 1999,  Concentra is aware of three  lawsuits that have been
filed by alleged  stockholders  of Concentra  relating to the Merger.  All three
lawsuits were filed in the Chancery Court for New Castle County,  Delaware. Each
of the lawsuits names  Concentra,  its directors and Yankee as  defendants.  The
plaintiff  in each  lawsuit  seeks to  represent a putative  class of all public
holders of Concentra common stock. The lawsuits allege, among other things, that
the  directors of  Concentra  breached  their  fiduciary  duties to  Concentra's
stockholders  by approving the Merger.  The lawsuits  seek,  among other things,
preliminary  and permanent  injunctive  relief  prohibiting  consummation of the
Merger, unspecified damages, attorneys' fees and other relief. Concentra expects
that these  lawsuits  will be  consolidated  into a single  action.  The Company
intends to contest these lawsuits vigorously.

ITEM 10. DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT


DIRECTORS


GOVERNANCE OF THE COMPANY; BOARD OF DIRECTORS AND COMMITTEES

     Pursuant to the Delaware  General  Corporation  Law, as  implemented by the
Company's  Certificate of Incorporation and Bylaws,  the business,  property and
affairs  of the  Company  are  managed  under  the  direction  of the  Board  of
Directors.  Members of the Board are kept  informed  of the  Company's  business
through  discussions  with the Chairman,  the President and other  officers,  by
reviewing  materials  provided to them and by  participating  in meetings of the
Board and its committees.

     The Board of  Directors  is divided  into three  classes  and is  presently
comprised  of eight  members.  The  directors  of each  class  are  elected  for
three-year  terms,  with terms of the three classes  staggered so that directors
from a single class are elected at each annual meeting of  stockholders.  George
H. Conrades,  Robert A.  Ortenzio,  and Lois E. Silverman are Class II directors
whose terms of office expire at the annual meeting of stockholders in 1999. John
K.  Carlyle is a Class III director  whose term of office  expires at the annual
meeting of  stockholders  in 2000.  Hon.  Willis D. Gradison,  Jr.,  Mitchell T.
Rabkin,  M.D.,  Richard D. Rehm, M.D. and Daniel J. Thomas are Class I directors
whose terms of office expire at the annual meeting of stockholders in 2001.

         During  1998,  the  Board of  Directors  held a total  of 13  meetings,
including 4 regular meetings and 9 special meetings. Each director attended more
than 75% of the  aggregate of (i) the total number of meetings held by the Board
of Directors and (ii) the total number of meetings held by all committees of the
Board of Directors on which he served.


COMMITTEES OF THE BOARD OF DIRECTORS

         During  1998,  the Board of  Directors  of the Company had two standing
committees: an Audit Committee and an Option and Compensation Committee.

     The Audit Committee held two meetings in 1998. The Audit Committee  reviews
the  adequacy  of the  Company's  system of  internal  controls  and  accounting
practices.  In  addition,  the Audit  Committee  reviews the scope of the annual
audit of the Company's  independent  public  accountants,  Arthur  Andersen LLP,
prior to its  commencement,  and  reviews  the types of  services  for which the
Company retains Arthur  Andersen LLP.  Commencing in December 1998, the Board of
Directors  designated the Audit Committee as the committee  charged with primary
oversight  of  the  Company's  Corporate  Integrity  Program,   currently  under
development.

     The  Option and  Compensation  Committee  held six  meetings  in 1998.  The
functions  of the Option and  Compensation  Committee  are to  establish  annual
salary levels,  approve fringe benefits and administer any special  compensation
plans or programs  for  officers of the  Company,  review and approve the salary
administration  program for the Company and administer  the Company's  incentive
and stock option plans.

     Hon.  Willis  D.  Gradison,  Jr.,  Mitchell  T.  Rabkin,  M.D.  and Lois E.
Silverman  currently serve on the Audit  Committee.  John K. Carlyle,  George H.
Conrades and Robert A. Ortenzio  currently serve on the Option and  Compensation
Committee.


VOTING AGREEMENT

     Pursuant to an agreement  entered into between Lois E. Silverman and Donald
J. Larson, Mr. Larson has agreed to vote his shares in favor of Ms. Silverman or
her designee as a member of the Board for as long as Ms.  Silverman,  her family
and trusts established by her hold at least 519,113 shares of Common Stock.

(1) The vesting of each option is cumulative,  and no vested portion will expire
    until the  expiration  of the option.  These  options  vest over a four-year
    period beginning on the January 1 subsequent to the date of the grant,  with
    25% of the  options  vesting and  becoming  exercisable  on each  subsequent
    January 1. All options will vest immediately upon the occurrence of a change
    in control triggering event, which includes a consolidation or merger of the
    stock of the Company,  or a sale of  substantially  all of the assets of the
    Company.   The   Merger  of  the   Company   with   Yankee   (see  "Item  1.
    Business-General") would be considered a change in control triggering event,
    and, therefore,  all unexercisable shares would become vested at the time of
    the Merger.

(2) These amounts represent  certain assumed rates of appreciation  only. Actual
    gains,  if any,  on stock  option  exercises  will  depend  upon the  future
    performance of the Common Stock.

(1) The awards listed in the table relate to the  performance  period  beginning

    growth objective. All options will vest immediately upon the occurrence of a
    change in control triggering event, which includes a consolidation or merger
    of the stock of the Company, or a sale of substantially all of the assets of
    the  Company.   The  Merger  of  the  Company  with  Yankee  (see  "Item  1.

COMPENSATION OF DIRECTORS

     Concentra  pays each  non-employee  Director  an annual  fee of  $15,000 in
restricted  stock (subject to pro-rata  forfeiture in the event a director fails
to  attend  at  least  75% of board  meetings  in such  year)  and  grants  each
non-employee  Director  options  each year to acquire  5,000 shares of Concentra
Common Stock.  Each annual grant of options  vests,  and the  restrictions  with
respect to each annual grant of  restricted  stock  lapses,  after one year.  In
addition, each of the Company's Directors receives reimbursement of all ordinary
and  necessary  expenses  incurred  in  attending  any  meeting  of the Board of
Directors  or any  committee  of the Board of  Directors.  The Company  does not
otherwise compensate,  and does not anticipate  compensating,  its Directors for
their services as Directors.

     The Company has entered into  employment  agreements with Daniel J. Thomas,
James M. Greenwood,  Richard A. Parr II, Joseph F. Pesce,  W. Tom Fogarty,  M.D.
and Kenneth  Loffredo.  Each of the agreements  provides for the payment of base
salary  amounts,  bonuses at the discretion of the Company's  Board of Directors
and  participation  in any employee  benefit plan adopted by the Company for its
employees. The term of each of the agreements is two years, subject to automatic
renewal for additional  terms of one year each. Each of the agreements  entitles
each such  individual to receive  severance  payments if the Company  terminates
such  individual's  employment  without cause or the  individual  terminates his
employment for good reason.  Such severance payments shall equal two years' base
salary for Mr.  Thomas and one year's base salary for Messrs.  Greenwood,  Parr,
Pesce, Fogarty and Loffredo. The Employment Agreements also provide that, if the
Company


                                       37

terminates  such  individual's   employment  without  cause  or  the  individual
terminates  his  employment  for a defined  reason  within one year  following a
change in control of the Company  which  occurs on or before  December 31, 1999,
the  severance  payments to which the  individuals  would be  entitled  would be
increased to two and one-half  years' base salary for Mr.  Thomas and two year's
base salary for Messrs. Greenwood, Parr, Pesce, Fogarty and Loffredo.


INDEMNITY AGREEMENTS AND LIMITATIONS ON DIRECTORS' LIABILITY

     The  Company  has  entered  into  indemnity  agreements  with  each  of its
Directors  and executive  officers.  Pursuant to these  agreements,  the Company
will, to the extent  permitted  under  applicable  law,  indemnify these persons
against all expenses, judgments, fines and penalties incurred in connection with
the defense or settlement of any actions  brought  against them by reason of the
fact that they are or were  Directors  or  officers  of the Company or that they
assumed certain responsibilities at the direction of the Company.

     In  addition,  the  Company's  Certificate  of  Incorporation  provides for
certain  limitations  on  Director  liability.   The  Company's  Certificate  of
Incorporation  provides  that no  Director of the  Company  shall be  personally
liable to the Company or its  stockholders  for  monetary  damages for breach of
fiduciary  duty as a director,  except for  liability  (i) for any breach of the
Director's duty of loyalty to the Company or its stockholders,  (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation  of law,  (iii) in respect of certain  unlawful  dividend  payments or
stock  redemptions or repurchases,  or (iv) for any  transaction  from which the
Director derived an improper personal benefit. The effect of these provisions is
to  eliminate  the  rights  of  the  Company  and  its   stockholders   (through
stockholders'  derivative  suits on behalf of the  Company) to recover  monetary
damages against a Director for breach of fiduciary duty as a director (including
breaches  resulting from grossly negligent  behavior),  except in the situations
described above.


COMPENSATION PLANS


1997 LONG-TERM INCENTIVE PLAN

     GENERAL

     The Company may grant  awards with  respect to shares of Common Stock under
the Company's 1997 Long-Term  Incentive Plan (the "Incentive Plan") to officers,
directors,  employees and certain consultants and advisors. The awards under the
Incentive Plan include (i) incentive stock options  qualified as such under U.S.
Federal  income tax laws,  (ii) stock  options  that do not qualify as incentive
stock options,  (iii) stock appreciation rights ("SARs"),  (iv) restricted stock
awards and (v) performance units.

     The number of shares of Common  Stock  that may be  subject to  outstanding
awards under the  Incentive  Plan at any one time is equal to ten percent of the
total number of outstanding  shares of Common Stock (treating as outstanding all
shares of Common Stock issuable within 60 days upon exercise of stock options or
conversion  or  exchange  of   outstanding,   publicly-traded   convertible   or
exchangeable  securities  of the  Company)  minus the total  number of shares of
Common Stock  subject to  outstanding  awards under the  Incentive  Plan and any
stock-based  plan for  employees or directors of the Company  adopted  after the
adoption  of the  Incentive  Plan.  The  number of shares  authorized  under the
Incentive  Plan and the number of shares subject to an award under the Incentive
Plan will be adjusted  for stock  splits,  stock  dividends,  recapitalizations,
mergers and other changes affecting the capital stock of the Company.

         The Board of Directors or any committee designated by it may administer
the Incentive Plan (the "Committee").  The Option and Compensation  Committee of
the Board of Directors is currently  designated  as the  Committee to administer
     the Incentive Plan. The Committee has broad discretion to administer the
Incentive Plan, interpret its provisions and adopt policies for implementing the
Incentive Plan. This discretion  includes the ability to select the recipient of
an award,  determine  the type and amount of each award,  establish the terms of
each  award,  accelerate  vesting  or  exercisability  of an award,  extend  the
exercise period for an award, determine whether performance conditions have been
satisfied,  waive conditions and provisions of an award,  permit the transfer of
an award to family trusts and other  persons and  otherwise  modify or amend any
award under the Incentive  Plan.  Nevertheless,  no awards for more than 250,000
shares or more than $2.5 million in cash may be granted to any one employee in a
calendar year.


                                       38



<PAGE>

     AWARDS


     The Committee  determines  the exercise  price of each option granted under
the Incentive Plan. The exercise price for an incentive stock option must not be
less than the fair market  value of the Common  Stock on the date of grant,  and
the exercise price of  non-qualified  stock options must not be less than 85% of
the fair market  value of the Common Stock on the date of grant.  Stock  options
may be exercised as the Committee determines,  but not later than ten years from
the date of grant in the case of incentive  stock options.  At the discretion of
the  Committee,  holders  may use  shares  of stock to pay the  exercise  price,
including shares issuable upon exercise of the option. Under the Incentive Plan,
each  non-employee  Director who is a director of the Company as of both the day
immediately preceding the annual meeting of stockholders and the day immediately
following  that annual  meeting shall  automatically  be granted a  Nonstatutory
Option for the purchase of 5,000  shares of Common Stock and a Restricted  Stock
Award having a fair market  value of $15,000  effective on the date of the first
meeting of the Board of Directors following that annual meeting,  whether or not
that director is in attendance at that Board meeting.


     An SAR may be awarded in  connection  with or separate from a stock option.
An SAR is the right to receive an amount in cash or stock equal to the excess of
the fair  market  value of a share of the Common  Stock on the date of  exercise
over the exercise price  specified in the agreement  governing the SAR (for SARs
not granted in  connection  with a stock  option) or the  exercise  price of the
related stock option (for SARs granted in connection  with a stock  option).  An
SAR granted in  connection  with a stock  option will  require the holder,  upon
exercise,  to surrender the related stock option or portion thereof  relating to
the  number of shares  for which the SAR is  exercised.  The  surrendered  stock
option or portion will then cease to be exercisable.  Such an SAR is exercisable
or transferable  only to the extent that the related stock option is exercisable
or  transferable.  An SAR  granted  independently  of a  stock  option  will  be
exercisable  as the  Committee  determines.  The  Committee may limit the amount
payable  upon  exercise  of any SAR.  SARs may be paid in cash or stock,  as the
Committee provides in the agreement governing the SAR.

     A  restricted  stock  award is a grant of shares of Common  Stock  that are
nontransferable  or subject to risk of forfeiture until specific  conditions are
met.  The  restrictions  will  lapse  in  accordance  with a  schedule  or other
conditions as the  Committee  determines.  During the  restriction  period,  the
holder of a  restricted  stock award may, in the  Committee's  discretion,  have
certain rights as a  stockholder,  including the right to vote the stock subject
to the award or receive  dividends on that stock.  Restricted  stock may also be
issued upon exercise or settlement of options, SARs or performance units.

     Performance units are performance-based  awards payable in cash, stock or a
combination  of both.  The  Committee  may  select  any  performance  measure or
combination of measures as conditions for cash payments or stock issuances under
the Incentive Plan, except that performance measures for executive officers must
be  objective  measures  chosen  from  among the  following  choices:  (a) total
stockholder return (Common Stock  appreciation plus dividends);  (b) net income;
(c)  earnings  per  share;  (d) cash flow per share;  (e) return on equity;  (f)
return  on  assets,  (g)  revenues;  (h)  costs;  (i) costs as a  percentage  of
revenues;  (j) increase in the market price of Common Stock or other securities;
(k) the  performance of the Company in any of the items  mentioned in clause (a)
through (j) in comparison to the average  performance of the companies  included
in the Nasdaq  Health  Services  Stocks  Index;  or (1) the  performance  of the
Company in any of the items mentioned in clause (a) through (j) in comparison to
the average  performance of the companies used in a self-constructed  peer group
established  before the beginning of the performance  period.  The Committee may
choose different  performance  measures if the  stockholders so approve,  if tax
laws  or  regulations  change  so as  not to  require  stockholder  approval  of
different measures in order to deduct the compensation  related to the award for
federal income tax purposes,  or if the Committee  determines  that it is in the
Company's  best  interest to grant awards not  satisfying  the  requirements  of
Section 162(m) of the Internal Revenue Code or any successor law.


     OTHER PROVISIONS


     At the Committee's  discretion and subject to conditions that the Committee
may impose,  a  participant's  tax  withholding  with respect to an award may be
satisfied  by the  withholding  of shares of  Concentra  Common  Stock  issuable
pursuant to the award or the  delivery of  previously  owned shares of Concentra
Common Stock, in either case based on the fair market value of the shares.


                                       39



<PAGE>

     The  Committee  has  discretion  to  determine  whether an award  under the
Incentive  Plan will have  change-of-control  features.  The Committee  also has
discretion to vary the change of control features as its deems appropriate.  The
following  describes the change of control  features that the Company  generally
expects may apply to additional  awards,  if any such feature applies.  An award
agreement under the Incentive Plan may provide that, upon a change of control of
the Company with  respect to awards held by  Participants  who are  employees or
directors at the occurrence of the change of control,  (1) all outstanding  SARs
and options will become  immediately  and fully vested and  exercisable in full,
(2) the restriction period on any restricted stock award will be accelerated and
the restrictions will expire, and (3) the target payout  opportunity  attainable
under the  performance  units will be deemed to have been  fully  earned for all
performance  periods as of the  effective  date of the change in control and the
holder  will  be paid a pro  rata  portion  of all  associated  targeted  payout
opportunities  (based on the number of  complete  and  partial  calendar  months
elapsed as of the change of control) in cash within  thirty days  following  the
change of control or in stock  effective  as of the change of control,  for cash
and stock-based performance units, respectively. The award may also provide that
it will remain  exercisable  for its original term whether or not  employment is
terminated at or following a change in control.  In general, a change in control
of the Company  occurs in any of four  situations:  (1) a person  other than the
Company or certain affiliated  companies or benefit plans becomes the beneficial
owner of 20% or more of the voting  power of the  Company's  outstanding  voting
securities (except acquisitions from the Company or in a transaction meeting the
requirements of the parenthetical exception in clause (3) below); (2) a majority
of  the  Board  of  Directors  is not  comprised  of the  members  of the  Board
immediately  following  August 29, 1997 and persons whose elections as directors
were approved by those directors or their approved  successors;  (3) the Company
merges or consolidates with another  corporation or entity (whether Concentra or
the other entity is the survivor),  or the Company and the holders of the voting
securities of such other corporation or entity (or the stockholders of Concentra
and such other  corporation  or entity)  participate  in a  securities  exchange
(other  than a  merger,  consolidation  or  securities  exchange  in  which  the
Company's  voting  securities  are  converted  into  or  continue  to  represent
securities  having the majority of voting  power in the  surviving  company,  in
which no  person  other  than  that  surviving  company  owns 20% or more of the
outstanding   shares  of  common  stock  or  voting   shares  of  the  surviving
corporation,  and in which at least a majority of the board of  directors of the
surviving corporation were members of the incumbent board of Concentra);  or (4)
Concentra  liquidates or sells all or  substantially  all of its assets,  except
sales to an entity having substantially the same ownership as Concentra.

     If a restructure  of Concentra  occurs that does not constitute a change in
control of Concentra,  the Committee may (but need not) cause  Concentra to take
any one or more of the following actions: (1) accelerate in whole or in part the
time of vesting and  exercisability  of any outstanding  stock options and stock
appreciation  rights  in order to  permit  those  stock  options  and SARs to be
exercisable before,  upon or after the completion of the restructure;  (2) grant
each optionholder  corresponding  cash or stock SARS; (3) accelerate in whole or
in part the  expiration  of some or all of the  restrictions  on any  restricted
stock  award;  (4) treat the  outstanding  performance  units as having fully or
partially  met their targets and pay, in full or in part,  the targeted  payout;
(5) if the  restructure  involves a  transaction  in which  Concentra is not the
surviving  entity,  cause the surviving entity to assume in whole or in part any
one or more of the  outstanding  awards under the Incentive Plan upon such terms
and provisions as the Committee  deems  desirable;  or (6) redeem in whole or in
part any one or more of the outstanding awards (whether or not then exercisable)
in  consideration  of a cash payment,  adjusted for withholding  obligations.  A
restructure  generally  is any merger of the  Company or the direct or  indirect
transfer of all or  substantially  all of the Company's assets (whether by sale,
merger, consolidation,  liquidation or otherwise) in one transaction or a series
of transactions.

     Without  stockholder  approval,  the Board of  Directors  may not amend the
Incentive Plan to increase  materially the aggregate  number of shares of Common
Stock  that may be issued  under the  Incentive  Plan  (except  for  adjustments
pursuant to the terms of the Incentive Plan). Otherwise,  the Concentra Board of
Directors  may at any  time and  from  time to time  alter,  amend,  suspend  or
terminate  the  Incentive  Plan in whole or in part and in any way,  subject  to
requirements  that may exist in stock exchange  rules or in securities,  tax and
other laws from time to time.  No award may be issued under the  Incentive  Plan
after August 29, 2007.


OTHER OUTSTANDING OPTIONS AND WARRANTS

         In addition to the options and awards  granted under the Incentive Plan
and  warrants to purchase  350,000  shares of Common Stock for $7.00 per Warrant
granted to  Creditanstalt-Bankverein  (of which 200,000 were  unexercised  as of
December  31,  1998),  the Company has as of December 31, 1998 issued or assumed
from its


                                       40



<PAGE>

predecessors or acquired  companies options or warrants to purchase an aggregate
of 2,525,564 shares of Common Stock pursuant to separate  agreements between the
Company  and the holders  thereof.  The  2,525,564  options  that are  currently
outstanding  have an average exercise price of $15.96 per share, and are subject
to various vesting provisions.

     Unexercised options and warrants,  and their exercise price, are subject to
adjustment  if the Company  issues  Common Stock for a price per share less than
the  exercise  price  or if  there  is a  subdivision  or  consolidation  of the
Company's  Common Stock,  the payment of a stock  dividend or other  increase or
decrease in the number of shares of Common  Stock  outstanding,  and the Company
does not receive compensation  therefor.  In addition,  the number (and type) of
securities  subject to an option or warrant  are  subject to  adjustment  if the
Company is party to a merger or consolidation.


401(K) PLAN

     The Company has a defined contribution  retirement plan which complies with
Section 401(k) of the Internal Revenue Code.  Substantially all employees of the
Company,  including  certain  officers and  Directors  of the Company,  who have
completed  six months of service are eligible to  participate  in the  Concentra
Managed Care, Inc. 401(k) Plan (the "Plan"). Generally, Employees may contribute
amounts up to a maximum of 15% of the employee's  compensation.  Under the Plan,
the  Company  has the  option  of  matching  up to 50% of  participants'  pretax
contributions up to a maximum of 6% of  compensation.  For fiscal year 1998, the
Company elected to match 50% of up to 4% of compensation.


EMPLOYEE STOCK PURCHASE PLAN

     Until March 2, 1999, the Company maintained an Employee Stock Purchase Plan
that permitted substantially all employees to acquire the Company's Common Stock
at the end of each  specified  period at a purchase price of 85% of the lower of
the fair market value at the beginning or the end of the  participation  period.
Periods  were  semi-annual  and  began on  January  1 and  July 1 of each  year.
Employees were allowed to designate up to 15% of their base compensation for the
purchase of Common Stock. The Option and Compensation Committee administered the
Employee  Stock  Purchase  Plan. On March 2, 1999,  the Company  terminated  the
Employee Stock Purchase Plan. The final period for which participating employees
acquired shares of the Company's common stock began on January 1, 1999 and ended
March 2, 1999.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

John  K. Carlyle,  Concentra's non-employee  Chairman, has served as a member of
the Option and Compensation Committee since December, 1998.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     The following table sets forth certain information regarding the amount and
nature of the beneficial  ownership of the Common Stock as of March 15, 1999, by
(i) each  person  known by the Company to own  beneficially  more than 5% of any
class of the Company's outstanding voting securities, (ii) each of the Company's
directors,  (iii) each  currently-employed  officer of the Company  named in the
Summary  Compensation  Table  under  the  heading   "Compensation  of  Executive
Officers," and (iv) all current directors and executive  officers of the Company
as a group. Unless otherwise indicated, the Company believes that each person or
entity  named below has sole  voting and  investment  power with  respect to all
shares  shown as  beneficially  owned  by such  person  or  entity,  subject  to
community  property laws where  applicable and the  information set forth in the

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     On March 2, 1999,  Concentra entered into the Merger Agreement with Yankee.
On March 24, 1999,  Concentra  entered into the Amended  Merger  Agreement  with
Yankee, amending the Merger Agreement. The Amended Merger Agreement contemplates
the Merger of Yankee with and into  Concentra.  As a result of the Merger,  each
outstanding  share of Concentra Common Stock will be converted into the right to
receive  $16.50 in cash.  The Merger is  conditioned  upon,  among other things,
approval by the  stockholders  of  Concentra,  receipt of financing  and certain
regulatory  approvals.  The  transaction  is structured to be accounted for as a
recapitalization.

     Lois E.  Silverman,  a Director of the Company,  is one of the trustees and
beneficiaries  of Colonial  Realty  Trust,  which leases  twelve  offices to the
Company for an annual aggregate  consideration of $700,000. The Company believes
that the rental  rates paid to  Colonial  Realty  Trust are fair  market  rental
rates.

     The Company is party to a Registration  Rights Agreement with Comprehensive
Rehabilitation  Associates  Inc., J.H.  Whitney & Co., Whitney 1990 Equity Fund,
L.P.,  Whitney  Subordinated  Debt Fund,  L.P.,  First  Union  Corporation,  Ms.
Silverman  and  Donald J.  Larson,  which  was  entered  into on March 8,  1994.
Pursuant to the Registration  Rights  Agreement,  the holders of at least 25% of
the shares of Common Stock of the Company  subject to the  Agreement  (excluding
Ms. Silverman and Mr. Larson) may require the Company to effect the registration
of the shares of Common  Stock of the Company  held by such  parties for sale to
the public on three occasions, subject to certain conditions and limitations. In
addition,  under the terms of the Registration Rights Agreement,  if the Company
proposes to register any of its  securities  under the  Securities  Act of 1933,
whether for its own account or otherwise, the parties to the Registration Rights
Agreement  (including  Ms.  Silverman  and Mr.  Larson) are  entitled to receive
notice of such  registration  and to include  their shares  therein,  subject to

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors of
Concentra Managed Care, Inc.:

We have  audited  the  accompanying  consolidated  balance  sheets of  Concentra
Managed Care,  Inc. (a Delaware  corporation)  as of December 31, 1997 and 1998,
and  the  related  consolidated   statements  of  operations,   cash  flows  and
stockholders'  equity for each of the three years in the period  ended  December
31, 1998.  These financial  statements are the  responsibility  of the Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements  based on our audits.  We  conducted  our audits in  accordance  with
generally accepted auditing standards.  Those standards require that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the financial position of Concentra Managed Care, Inc. as
of December 31, 1997 and 1998,  and the results of its  operations  and its cash
flows for each of the three years in the period  ended  December  31,  1998,  in
conformity with generally accepted accounting principles.

                         CONCENTRA MANAGED CARE, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) BASIS OF PRESENTATION

     On August 29,  1997,  Concentra  Managed  Care,  Inc.  ("Concentra"  or the
"Company"), a Delaware corporation, was formed by the merger (the "1997 Merger")
of CRA Managed Care, Inc. ("CRA") and OccuSystems,  Inc.  ("OccuSystems").  As a
result of the 1997  Merger,  CRA  changed  its name to  Concentra  Managed  Care
Services,  Inc.  ("Managed Care Services") and OccuCenters,  Inc., the operating
subsidiary of OccuSystems,  changed its name to Concentra Health Services,  Inc.
("Health  Services").  The 1997 Merger was a tax-free  stock for stock  exchange
accounted for as a pooling of interests.  The Company  recorded a  non-recurring
charge of  $38,625,000  in the third  quarter of 1997  associated  with the 1997
Merger.   The  utilization  of  this  charge  through  December  31,  1998,  was
approximately  $11,569,000 for  professional  fees and services,  $16,216,000 in
costs  associated with personnel  reductions and the  consolidation of CRA's and
OccuSystems'  employee  benefits,  $5,945,000  in  facility  consolidations  and
closings, $2,541,000 for the write-off of start-up costs and $2,354,000 of other
charges.  At December 31, 1997,  approximately  $7,527,000 of the  non-recurring
charge  remains  primarily  related to  personnel  related  charges and facility
consolidations and closings.

     On February 24, 1998, the Company  acquired all of the  outstanding  common
stock of Preferred  Payment Systems,  Inc. ("PPS") of Naperville,  Illinois,  in
exchange for  approximately  7,100,000  shares of Concentra  common  stock,  the
assumption of PPS options  totaling  approximately  580,000  shares of Concentra
common stock, the payment of approximately $15,047,000 in cash to dissenting PPS
shareholders and the assumption of  approximately  $49,000,000 of debt which was
repaid at the time of the merger.  This merger was accounted for as a pooling of
interests.  In the first quarter of 1998, the Company  recorded a  non-recurring
charge  of  $12,600,000  primarily  associated  with  the  merger  of  PPS.  The
utilization  of  this  charge  through  December  31,  1998,  was  approximately
$5,136,000 for  professional  fees and services,  $2,355,000 in costs associated
with personnel  reductions,  $746,000 in facility  consolidations  and closings,
$1,627,000  associated  with the  write-off  of deferred  financing  fees on PPS
indebtedness  retired and $1,264,000 of other  non-recurring  costs. At December
31, 1998, approximately $1,472,000 of the non-recurring charge remains primarily
related to remaining  facility  lease  obligations.  PPS,  founded in 1990, is a
provider of retrospective bill review services for the group healthcare market.

     In the fourth quarter of 1998, the Company recorded a non-recurring  charge
of $20,514,000  primarily associated with the reorganization of its Managed Care
Services  division to improve  efficiency  through facility  consolidations  and
related headcount reductions,  to recognize an impairment loss on the intangible
related to an acquired  contract and costs  associated  with settling  claims on
other expired  contracts.  The  utilization of this charge through  December 31,
1998, was  approximately  $7,416,000 in charges related to the recognition of an
impairment loss on the intangible related to an acquired contract, $2,490,000 in
costs   associated   with  personnel   reductions  and  $1,140,000  in  facility
consolidations.   At  December  31,  1998,   approximately   $9,468,000  of  the
non-recurring  charge  remains  primarily  related to remaining  facility  lease
obligations  and  costs   associated  with  settling  claims  on  other  expired
contracts.

     The  financial  statements  as of December 31, 1997 and for the years ended
December  31,  1996 and 1997 have been  restated to reflect the merger of PPS in
accordance  with  Accounting   Principles   Board  Opinion  No.  16,   "Business
Combinations" ("APB 16").


(2) SIGNIFICANT ACQUISITIONS

     Managed Care Services has experienced a significant amount of its growth by
virtue of the  acquisitions  of FOCUS  HealthCare  Management,  Inc.  ("FOCUS"),
Prompt Associates,  Inc. ("PROMPT"),  First Notice Systems, Inc. ("FNS"),  About
Health,  Inc.  ("ABOUT HEALTH") and several other smaller  acquisitions.  Health
Services  has also  experienced  a  significant  amount of its  growth  from the
acquisition of practices,  including the acquisition of 16 occupational  medical
centers and  contracts to manage four  additional  medical  centers from Vencor,
Inc. ("VMC").

     On April 2, 1996,  the Company  purchased  FOCUS for  $21,000,000  in cash.
FOCUS,  based in  Brentwood,  Tennessee,  has  built  and  maintains  one of the
nation's largest workers'  compensation  preferred provider organization ("PPO")
networks and had annual revenues of approximately  $9,900,000 for the year ended
December 31, 1995.


                                      F-6



<PAGE>

     On October 29, 1996, the Company  purchased PROMPT for $30,000,000 in cash.
PROMPT,  which is based in Salt Lake City, Utah, is one of the leading providers
of hospital bill audit  services to the group health payor  community for claims
that fall outside of an indemnity carrier's, third-party administrator's ("TPA")
or health maintenance  organization's  ("HMO") network of hospital or outpatient
facilities and had annual  revenues of  approximately  $10,000,000  for the year
ended December 31, 1995.

     On June 4, 1997, the Company  purchased FNS for  $40,000,000 in cash.  FNS,
based in  Boston,  Massachusetts,  is a  leading  provider  of  outsourced  call
reporting  for first  notice of  loss/injury  to the  automobile  insurance  and
workers'  compensation  industries  and had  annual  revenues  of  approximately
$9,000,000 for the year ended December 31, 1996.
 
     PPS acquired  ABOUT HEALTH in a two-step  transaction on August 1, 1997 and
October 31, 1997 for $25,800,000 in cash and $9,733,000 in equity. ABOUT HEALTH,
based in Rockville,  Maryland, is a provider of specialized cost containment and
outsourcing   services  for  healthcare   payors  and  had  annual  revenues  of
approximately $10,000,000 for the year ended December 31, 1996.

     On  September  30, 1997,  the Company  purchased  16  occupational  medical
centers and the  management  of four  additional  medical  centers  from VMC for
approximately  $27,000,000 in cash. These medical centers had annual revenues of
approximately $23,000,000 for the year ended December 31, 1996.

     The  acquisitions  of FOCUS,  PROMPT,  FNS,  ABOUT HEALTH and VMC have been
accounted for by the Company as purchases  whereby the basis for  accounting for
their  assets and  liabilities  are based upon their fair values at the dates of
acquisition.  The  excess of the  purchase  price  over fair value of net assets
acquired  (goodwill and assembled  workforce and customer  lists, if applicable)
for the FOCUS,  PROMPT,  FNS, ABOUT HEALTH and VMC acquisitions was $19,900,000,
$29,550,000, $37,001,000, $34,291,000 and $29,585,000, respectively. Goodwill is
being  amortized  over thirty to forty year periods and assembled  workforce and
customer  lists  are  being   amortized  over  five-  and  seven-year   periods,
respectively.


(3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


(A) CONSOLIDATION

     The consolidated  financial  statements include the accounts of the Company
and its wholly-owned  subsidiaries.  All significant  intercompany  accounts and
transactions are eliminated in consolidation.

     Physician and physical therapy services are provided at the Health Services
centers under management agreements with affiliated physician  associations (the
"Physician  Groups"),  which are organized  professional  corporations that hire
licensed  physicians and physical  therapists to provide medical services to the
centers'  patients.  Since Health  Services  effectively  controls the Physician
Groups,  Health Services results of operations reflect the revenues generated by
the  Physician  Groups  and the  costs  associated  with the  delivery  of their
services.  The financial  statements of the  Physician  Groups are  consolidated
because Health Services has unilateral control over the assets and operations of
the  Physician  Groups  and,  notwithstanding  the  lack of  technical  majority
ownership,  consolidation  of the  Physician  Groups  with  Health  Services  is
necessary to present fairly the financial  position and results of operations of
Health  Services due to the  existence of a  parent-subsidiary  relationship  by
means other than record  ownership of the Physician  Group's  voting stock.  The
shareholders  of the  Physician  Groups  are the  physician  leaders  of  Health
Services  and  are  employed  by  Health  Services  or one  of its  wholly-owned
subsidiaries.  Through a shareholder  agreement,  Health Services  restricts any
transfer of Physician  Group  ownership  without its consent and can require the
holder of such shares to transfer  ownership to a Health Services  designee upon
the occurrence of certain events,  including but not limited to the cessation of
employment.  Control of the  Physician  Groups is perpetual due to the nature of
the  relationship  and the  management  agreements  between  the  entities.  The
employed physicians do not control fee schedules,  payor contracts or employment
decisions regarding personnel.  The risk of loss for billed services provided by
the Physician  Groups resides  ultimately  with Health  Services as Concentra is
required to provide financial support on an as-needed basis.


(B) CASH AND CASH EQUIVALENTS

     The Company  considers all highly liquid debt  instruments  purchased  with
original maturities of three months or less to be cash equivalents. The carrying
amount approximates fair value due to the short maturity of those instruments.


                                      F-7



<PAGE>

(C) REVENUE RECOGNITION

     The Company  recognizes  revenue  primarily as services  have been rendered
based on time and expenses incurred. A certain portion of the Company's revenues
are derived from fee schedule  auditing  which is based on the number of charges
reviewed  and  based on a  percentage  of  savings  achieved  for the  Company's
customers. In these circumstances,  the customer is obligated to pay the Company
when the services have been rendered and the savings identified.  During the fee
schedule  audit  process  (i.e.,  medical bill  review),  each bill reviewed and
audited is returned to the customer  accompanied  by an  Explanation  of Benefit
("EOB").  The EOB  details  the total  savings  with  respect  to the bill being
reviewed as well as the amount owed to the  Company as a  percentage  of savings
identified and the line charge associated with the bill being reviewed.
 

     Insurance  claims are  screened  by PPS and PROMPT  prior to the  insurance
company's  internal  review  procedures  to  determine  if the claims  should be
further negotiated or are payable by the insurance company. During the insurance
company's review process, some claims have pre-existing PPO or HMO arrangements,
or other  pre-existing  conditions  and  disqualifying  situations.  When  these
situations  occur,  a refund  (chargeback)  is  requested  for the amounts  paid
(invoiced)  on these  claims.  PPS and  PROMPT's  policies are to record a sales
allowance  as an offset to  revenues  and  accounts  receivable  based  upon the
historical  tracking of  discounts  and  chargebacks  at the time the claims are
modeled.  A portion of the allowance for doubtful  accounts  attributable to PPS
and PROMPT is based on  historical  experience  of  ineligible  claims which are
either  charged  back or given a  negotiated  discount.  PPS and PROMPT  utilize
several methods to project  unpresented  discounts and  chargebacks  including a
tracking of the actual experience of contractual  discounts.  Other factors that
affect collectability and bad debts for each service line are also evaluated and
additional allowance amounts are provided as necessary.

     Accounts  receivable  at December 31, 1997 and 1998 include  $4,500,000  of
unbilled accounts receivable relating to services rendered during the period but
not invoiced  until after the  period-end.  These unbilled  accounts  receivable
relate  primarily  to field  case  management  services,  which are billed on an
hourly  basis,  whereby the Company has not yet provided a sufficient  amount of
services to warrant the generation of an invoice. The customers are obligated to
pay for the services once performed.  The Company  estimates  unbilled  accounts
receivable by tracking and monitoring its historical experience.


(D) DEPRECIATION

     The Company  provides  for  depreciation  on property and  equipment  using
straight-line  and accelerated  methods by charges to operations in amounts that
allocate the cost of depreciable assets over their estimated lives as follows:



<TABLE>
<CAPTION>
ASSET CLASSIFICATION                           ESTIMATED USEFUL LIFE
- -------------------------------   -----------------------------------------------
<S>                               <C>
Furniture and fixtures                                7 Years
Office and computer equipment                       3 - 7 Years
Buildings and improvements                         30 - 40 Years
Leasehold improvements            The shorter of the life of lease or asset life
</TABLE>

(E) INTANGIBLE ASSETS

     The value of goodwill, assembled workforces and customer lists are recorded
at cost at the date of acquisition.  Goodwill, including any excess arising from
earn-out  payments,  is being  amortized  on a  straight-line  basis  over 30 to
40-year periods in accordance with  Accounting  Principles  Board Opinion No. 17
("APB No. 17"),  "Intangible  Assets". The Company believes that the life of the
core businesses acquired and the delivery of occupational healthcare services is
indeterminate  and  likely  to exceed 40 years.  The  assembled  workforces  and
customer  lists  are  being   amortized  over  five-  and  seven-year   periods,
respectively. As of December 31, 1997 and 1998, the Company recorded accumulated
amortization on intangible assets of $29,871,000 and $38,038,000, respectively.

     Subsequent to an acquisition,  the Company  continually  evaluates  whether
later events and  circumstances  have  occurred that indicate that the remaining
balance of goodwill may not be recoverable or that the remaining useful life may
warrant  revision.  When factors  indicate that goodwill should be evaluated for
possible  impairment,  the Company  uses an  estimate  of the  related  business
segment's  undiscounted  cash flows over the remaining  life of the goodwill and
compares it to the business segment's goodwill balance to determine whether the
 


                                      F-8



<PAGE>

goodwill is recoverable or if impairment  exists, in which case an adjustment is
made to the  carrying  value of the asset to reduce it to its fair  value  based
upon the present value of the future cash flows.  When an adjustment is required
the Company  evaluates the  remaining  goodwill  amortization  using the factors
outlined in APB No. 17.


(F) DEFERRED FINANCE COSTS

     The Company has capitalized costs associated primarily with the 6% and 4.5%
Convertible Subordinated Notes and the PPS indebtedness (written-off at the time
of the merger and  retirement of PPS  indebtedness)  and is amortizing  these as
interest  expense  over the life of the  notes.  Included  in  other  assets  at
December  31, 1997 and 1998 were  deferred  finance  costs,  net of  accumulated
amortization, of $4,515,000 and $7,592,000, respectively.


(G) DEFERRED START-UP COSTS

     Prior to the 1997 Merger,  Health  Services  capitalized the start-up costs
associated   with  the  internal   development  of  its  medical  centers  until
operational  and would  amortize  these  costs  over a  three-year  period.  The
American  Institute of Certified Public  Accountants issued Statement of Opinion
98-5,  "Accounting  for Start Up Costs" in April 1998, to change the  accounting
and  reporting  treatment  of  start-up  costs to require  start-up  costs to be
expensed  as  incurred.  As a  result  of  this  pending  change  in  accounting
principle,  the  Company  wrote-off  deferred  start-up  costs of  approximately
$2,541,000 and included this in the third quarter of 1997 non-recurring charge.
 


(H) FOREIGN CURRENCY TRANSLATION

     All assets and liabilities of the Company's Canadian offices are translated
at the year-end  exchange rate while revenues and expenses are translated at the
average  exchange rate for the year.  Cumulative  translation  adjustments  were
immaterial for the years ended December 31, 1996, 1997 and 1998.


(I) USE OF ESTIMATES

     The  preparation  of financial  statements  in  accordance  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and reported  amounts of revenues and expenses  during the reporting
period. Actual results could differ from those estimates.


(J) RECLASSIFICATIONS

     Certain  amounts  previously   reported  in  CRA's  and  OccuSystems'  1996
consolidated  financial statements and PPS' 1996 and 1997 consolidated financial
statements  have been  reclassified  to conform to the  presentation in the 1998
consolidated financial statements.


(K) NEW ACCOUNTING PRONOUNCEMENTS

     In the first  quarter  of 1998,  the  Company  adopted  the  provisions  of
Statement of Financial  Accounting  Standards No. 130, "Reporting  Comprehensive
Income" ("SFAS 130").  Comprehensive  income for the Company includes unrealized
gains on  marketable  securities  in  addition  to net income as reported in the
Company's   Consolidated   Statements  of   Stockholders'   Equity  and  in  the
Stockholders' Equity section of the Company's Consolidated Balance Sheets.

     In 1998,  the Company  adopted the  provisions  of  Statement  of Financial
Accounting  Standards No. 131,  "Disclosures about Segments of an Enterprise and
Related  Information" ("SFAS 131"). SFAS 131 requires the reporting of financial
and descriptive  information about a company's  reportable  operating  segments.
Operating  segments  are  components  of  an  enterprise's   separate  financial
information that is evaluated regularly by the chief operating decision maker in
deciding  how  to  allocate  resources  and in  assessing  performance  of  that
component.  The statement  requires  reporting  segment profit or loss,  certain
specific  revenue and expense items,  and segment assets.  See Note 13 - Segment
Information for disclosure


(4) PRO FORMA NET INCOME AND PRO FORMA EARNINGS PER SHARE

     Pro forma net income and basic and diluted pro forma earnings per share for
the years ended December 31, 1996 and 1997 have been calculated as if the merger
of PPS had been subject to federal and state income taxes


                                      F-9



<PAGE>

for  the  entire  period,  based  upon  an  effective tax rate indicative of the
statutory rates in effect.  Prior to its merger, PPS elected to be taxed as an S
corporation,  and accordingly, was not subject to federal and state income taxes
in certain jurisdictions.

     The  Financial  Accounting  Standards  Board issued  Statement of Financial
Accounting   Standards  No.  128,  "Earnings  Per  Share"  ("SFAS  128"),  which
supersedes  Accounting Principles Board Opinion No. 15. SFAS 128 establishes new
accounting  standards for the presentation of earnings per share whereby primary
earnings per share is replaced with "Basic Earnings Per Share" and fully diluted
earnings per share is now called  "Diluted  Earnings Per Share".  In  accordance
with SFAS 128, Basic  Earnings Per Share has been computed by dividing  reported
net income by weighted  average common shares  outstanding and Diluted  Earnings
Per Share  has been  computed  assuming,  if  dilutive,  the  conversion  of the
Company's  convertible notes and the elimination of the related interest expense
and the exercise of stock options, net of their related income tax effect.

     Basic and diluted earnings per share for the years ended December 31, 1996,

(1) Pro forma net income and basic and diluted pro forma  earnings per share for
    the years ended  December 31, 1996 and 1997 have been  calculated  as if PPS
    had been subject to federal and state  income  taxes for the entire  period,
    based  upon an  effective  tax rate  indicative  of the  statutory  rates in
    effect.  Prior to its merger with the Company, PPS elected to be taxed as an
    S corporation and, accordingly,  was not subject to federal and state income
    taxes in certain jurisdictions.

(2) Excludes  common  stock  equivalents  of  3,291,243  shares of Common  Stock
    related to the 6% Convertible Subordinated Notes issued in December 1996 and
    5,575,758   shares  of  Common  Stock   related  to  the  4.5%   Convertible
    Subordinated  Notes issued in March and April 1998 as they are anti-dilutive
    for the applicable years presented.


(5) REVOLVING CREDIT FACILITIES

     On September 17, 1997,  the Company  entered into the  $100,000,000  Senior
Credit  Facility  with a syndicate  of five banks  ("Senior  Credit  Facility"),
replacing the $60,000,000  Managed Care Services Credit  Facility,  ("MCS Credit
Facility") and the  $60,000,000  Health Services  Credit  Facility,  ("HS Credit
Facility").  The Senior Credit Facility matures on September 17, 2002.  Interest
on  borrowings  under the Senior  Credit  Facility is payable,  at the Company's
option,  at the higher of the bank's prime rate of interest or the federal funds
rate  plus an  additional  percentage  of  0.5%,  or  LIBOR  plus an  additional
percentage of up to 1.25%,  depending on certain financial criteria. The Company
is required to pay a commitment  fee of 0.125% to 0.25% per annum,  depending on
certain financial criteria, on the unused portion of the Senior Credit Facility.


                                      F-11



<PAGE>

     On  February  23,  1998,  the  Company  signed an  amendment  to expand the
Company's  borrowing  capacity under the Senior Credit  Facility to $200,000,000
under  similar  terms  and  conditions  in order to  finance  the  repayment  of
$49,000,000 of PPS  outstanding  indebtedness  (the PPS Credit  Facility and 10%
Subordinated  Notes).  On March 11, 1998, the Senior Credit  Facility  borrowing
capacity was reduced to the original $100,000,000 amount.

     The Senior Credit Facility contains customary covenants, including, without
limitation,  restrictions on the incurrence of indebtedness, the sale of assets,
certain  mergers and  acquisitions,  the payment of dividends  on the  Company's
capital stock, the repurchase or redemption of capital stock,  transactions with
affiliates,  investments,  capital  expenditures  and  changes in control of the
Company.  Under the Senior  Credit  Facility,  the  Company is also  required to
satisfy certain financial covenants, such as cash flow, capital expenditures and
other  financial  ratio  tests  including  fixed  charge  coverage  ratios.  The
Company's  obligations  under the Senior Credit Facility are secured by a pledge
of stock in the Company's subsidiaries.

     As a result of the fourth quarter 1998  non-recurring  charge,  the Company
was not in compliance  with certain  leverage ratio  covenants  under the Senior
Credit  Facility in the fourth  quarter of 1998 and the Company  expects it will
not be in  compliance  with those  covenants in the first  quarter of 1999.  The
Company received a waiver on all financial  covenants  through the first quarter
of 1999. The Company does not have any borrowings  outstanding  under the Senior
Credit  Facility  and does not  anticipate  the need to borrow  under the Senior
Credit Facility for the next twelve months.

     At December 31, 1997,  the Company had  borrowings  under the Senior Credit
Facility of  $49,000,000,  at an average rate of interest of 6.94%.  At December
31, 1998,  the Company had no  borrowings  and  $3,050,000  of letters of credit
outstanding  under the Senior Credit Facility.  For the years ended December 31,
1996,  1997 and 1998,  the weighted  average  borrowings  under these  revolving
credit facilities were $8,184,000, $9,615,000 and $14,205,000, respectively, and
the weighted average interest rates were 6.94%, 7.31% and 7.69%, respectively.

     On March 11, 1998, the Company issued a new issue of $200,000,000 aggregate
principal amount of 4.5% Convertible  Subordinated Notes due March 15, 2003 (the
"4.5%  Convertible  Subordinated  Notes").  On April 6, 1998,  the  underwriters
exercised  the  $30,000,000   overallotment   provision.  The  4.5%  Convertible
Subordinated Notes will be convertible into 5,575,758 shares of Common Stock, at
the  option  of  the  holder,  at  a  conversion  price  of  $41.25  per  share,
representing a conversion  premium of 25% over the previous day's closing price.
The 4.5% Convertible Subordinated Notes are general unsecured obligations of the
Company  ranking equal in right of payment with the 6% Convertible  Subordinated
Notes and all other  unsecured  indebtedness  of the Company.  In addition,  the
Company  is a  holding  company  that  conducts  all of its  operations  through
subsidiaries, and the 4.5% Convertible Subordinated Notes and the 6% Convertible
Subordinated  Notes  are  structurally  subordinate  to all  obligations  of the
Company's


                                      F-12



<PAGE>

subsidiaries.  The 4.5%  Convertible  Subordinated  Notes  were  sold  through a
private  placement under Rule 144A of the Securities Act of 1933, as amended and
have similar terms and conditions as the 6% Convertible Subordinated Notes.

     In December 1996,  Health Services issued an aggregate of up to $97,750,000
in  principal  amount of 6%  Convertible  Subordinated  Notes  ("6%  Convertible
Subordinated Notes"). The 6% Convertible  Subordinated Notes will be convertible
into 3,291,243 shares of Common Stock at the initial  conversion price of $29.70
per share  (equivalent to a conversion rate of 33.67 shares per $1,000 principal
amount of 6% Convertible  Subordinated Notes),  subject to adjustment in certain
events.  The notes are convertible into Common Stock at the option of the holder
on or after February  through  December  2001.  The 6% Convertible  Subordinated
Notes will mature on December 15, 2001 with interest being payable semi-annually
on June 15 and December 15 of each year, commencing on June 15, 1997.

     On August 31, 1996, PPS completed a series of transactions  involving funds
managed  by a  private  equity  firm  and  senior  officers  of PPS  (the  "1996
Transaction").  In connection with the 1996 Transaction, the private equity firm
invested $17,000,000 to acquire $10,000,000 in 5% Convertible Subordinated Notes
due August 2006 (the "5% Convertible  Subordinated Notes") and $7,000,000 of 10%
Subordinated  Notes due August  2003 (the "10%  Subordinated  Notes").  PPS also
entered into a credit facility with a syndicate of two banks, which provided for
$25,000,000 of senior debt,  $20,000,000 of which was in the form of a term loan
and  $5,000,000  of which was  available  pursuant to a line of credit.  PPS, in
turn,  used  the  net  proceeds  from  these  financing   transactions  to  make
distributions  to its  stockholders  in an  aggregate  amount  of  approximately
$36,000,000.

     On July 31, 1997, in connection  with the  acquisition of ABOUT HEALTH (see
Note 2), PPS entered into an amended and restated credit facility (as so amended
and  restated,  the "PPS Term Loan") to increase  the term loan portion by $26.5
million.  The Company is  obligated  to make  quarterly  principal  and interest
payments on the term loan  (bearing  interest  of 8.0% and 7.8% at December  31,
1996 and 1997,  respectively)  and  quarterly  interest  payments on the line of
credit  (bearing  interest  at 9.25%  and 9.0% at  December  31,  1996 and 1997,
respectively).

     The  10%  Subordinated  Notes  bear  interest  at 10%  per  annum,  payable
quarterly.  Beginning  February 2002, the Company is required to make semiannual
principal payments on the 10% Subordinated Notes of $1.7 million.  Under the 10%
Subordinated  Loan  Agreement,  the  Company  is  required  to  prepay  the  10%
Subordinated  Notes in whole  upon a  qualifying  public  offering,  sale of the
Company, or other change in control, as defined.

     The 5% Convertible  Subordinated  Notes are  convertible at any time by the
holder into 10,000 shares of PPS Redeemable Preferred Stock and 10,000 shares of
PPS Convertible Preferred Stock. The 5% Convertible Subordinated Notes mature in
August 2006,  subject to the right of the holders to accelerate  the maturity of
the  5%  Convertible  Subordinated  Notes  upon  a  public  equity  offering,  a
qualifying  sale of the Company,  or a merger  resulting in a change in majority
ownership of the Company. The 5% Convertible Subordinated Notes bear interest at
5%, 2% being payable quarterly and 3% being deferred and payable upon redemption
or maturity.

     On February  24,  1998,  in  connection  with the merger of PPS,  Concentra
repaid  $49,000,000 of PPS indebtedness  (the PPS Term Loan and 10% Subordinated
Notes) and the 5% Convertible  Subordinated  Notes were converted into 2,721,904
shares of Concentra Common Stock.


(7) FINANCIAL INSTRUMENTS

     Effective  December 31, 1995,  the Company  adopted  Statement of Financial
Accounting  Standards  No.  107,  "Disclosures  About  Fair  Value of  Financial
Instruments".  This  statement  requires  entities to disclose the fair value of
their financial  instruments,  both assets and liabilities,  on- and off-balance
sheet,  for which it is  practicable  to  estimate  fair  value.  The  following
describes the methods and assumptions  that were used to estimate the fair value
of each class of financial  instruments  for which it is practicable to estimate
that value.

     The  Company's  marketable  securities  are held as  available  for sale in
accordance  with the provisions of Statement of Financial  Accounting  Standards
No. 115, "Accounting for Certain Investments in Debt and Equity Securities".

</TABLE>

     The average maturity of the Company's marketable  securities as of December
31, 1998 was approximately 20 months.

     Financial   instruments   that   potentially   subject   the   Company   to
concentrations of credit risk are accounts receivable and marketable securities.
Mitigating  factors related to the Company's  accounts  receivable are that they
are spread  over a large  customer  base and various  product  lines the Company
offers.  Further, the Company does monitor the financial  performance and credit
worthiness of its large customers.  Mitigating  factors related to the Company's
marketable securities are that they are primarily U.S. government securities and
corporate bonds and notes,  with strong credit  ratings.  The Company limits the
amount of its  investment  exposure as to  institution,  maturity and investment
type.

     The carrying  amounts of cash and cash  equivalents,  accounts  receivable,
other current assets,  accounts payable,  and accrued expenses  approximate fair
value because of the short maturity of those instruments.  The credit facilities
approximate  fair value primarily due to the floating  interest rates associated
with those debt instruments.

     The fair  value of the  Company's  6%  Convertible  Subordinated  Notes was
$125,120,000  and $83,088,000 as of December 31, 1997 and 1998 and the Company's
4.5%  Convertible  Subordinated  Notes was $173,650,000 as of December 31, 1998.
The fair market values of the convertible  subordinated notes are the average of
the NASDAQ's bid and ask amounts as of the  respective  year end. As of December
31, 1997, the approximate fair value of the 5% Convertible Subordinated Notes is
$15,700,000.  Although the interest rate on the 10% Subordinated Notes is fixed,
the carrying value reasonably approximates the fair value at December 31, 1997.

     PPS'  shareholders  had elected S Corporation  taxing  status.  Thus,  PPS'
taxable income was taxed directly to its  shareholders.  PPS did pay state taxes
in  Illinois,  Pennsylvania,  California  and Utah based on its taxable  income.
Effective  with the merger with  Concentra,  PPS' taxable  income is included in
Concentra's consolidated income tax returns.


(9) STOCKHOLDERS' EQUITY


(A) PREFERRED STOCK


     The Board of Directors is authorized to issue shares of Preferred Stock, in
one or more series, and to fix for each such series the number of shares thereof
and voting powers and such preferences and relative, participating,  optional or
other special rights and such qualifications, limitations or restrictions as are
permitted by the Delaware General  Corporation Law. The Board of Directors could
authorize  the issuance of shares of Preferred  Stock with terms and  conditions
that could discourage a takeover or other  transaction that holders of some or a
majority of shares of Common Stock might  believe to be in their best  interests
or in which such holders  might receive a premium for their shares of stock over
the then  market  price of such  shares.  As of the date  hereof,  no  shares of
Preferred  Stock are  outstanding  and the  Board of  Directors  has no  present
intention  to issue  any  shares of  Preferred  Stock.  See Note 14  "Subsequent
Events" for related disclosure.


                                      F-15



<PAGE>

(B) STOCKHOLDER RIGHTS PLAN

     Shortly  after  the 1997  Merger,  on  September  17,  1997,  the  Board of
Directors declared,  pursuant to a rights agreement (the "Rights Agreement"),  a
dividend  distribution  of one common share  purchase  right  ("Right") for each
outstanding share of Common Stock. Each Right will entitle the registered holder
to  purchase  from  Concentra  one  thousandth  of a share  of  Series  A Junior
Participating  Preferred Stock, par value $.01 per share (the "Junior  Preferred
Shares"),  of  Concentra at a price per share to be  determined  by the Board of
Directors with the advice of its financial advisor about the long-term prospects
for the Company's  value (the "Purchase  Price"),  subject to  adjustment.  Each
thousandth of a Junior  Preferred Share will be  economically  equivalent to one
share  of  Concentra  Common  Stock.  The  Purchase  Price  is  expected  to  be
significantly higher than the trading price of the Common Stock. Therefore,  the
dividend will have no initial value and no impact on the consolidated  financial
statements  of  the  Company.  See  Note  14, "Subsequent  Events"  for  related
disclosure.


(C) COMMON STOCK

     At December 31, 1998,  the Company has  reserved  approximately  16,839,000
unissued  shares of its Common Stock for possible  issuance  under the Company's
stock  option  or  stock  purchase  plans  and for the  issuance  upon  possible
conversion of the Company's 6% and 4.5% Convertible Subordinated Notes.


(10) COMMITMENTS AND CONTINGENCIES

     The Company leases certain  corporate  office space,  operating and medical
facilities,  and office  and  medical  equipment  under  various  non-cancelable
operating and capital lease  agreements.  Certain  facility  leases  require the
Company to pay increases in operating  costs and real estate taxes. In addition,
the  Company  leases  certain  office  facilities  from  related  parties  under
operating  lease  agreements  that expire on various dates through  December 31,
2003. The Company made rental  payments of $726,000 to Colonial  Realty Trust, a
real estate  company owned by a shareholder  and board member of the Company for
each of the years ended  December 31, 1996,  1997 and 1998.  The  following is a

     A  wholly-owned  subsidiary  of Health  Services has committed to guarantee
$21,408,000 in senior discount notes, plus interest,  issued by four development
corporations   (Concentra   Development   Corporation,   Concentra   Development
Corporation II,  Concentra/Sherrer  Development  Corporation and  Concentra/RDA,
Inc.). The stated principal amount of the notes total $42,768,000, which will be
their accreted value at their stated  maturity (two to five years after the date
of  issuance  of  each  note).   These  corporations  have  been  organized  and
capitalized  by a third  party to  develop  occupational  healthcare  centers in
selected  markets in the United  States.  Health  Services also has the right to
acquire

the developed  centers at fair market value in the future.  Health  Services has
entered into a management agreement with the development  corporations to manage
the healthcare centers' daily operations.

     The  Company is party to certain  claims and  litigation  initiated  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.  See Note
14, "Subsequent Events" for further claims and litigation disclosures.
 


(11) EMPLOYEE BENEFIT PLANS


(A) CONCENTRA 401(K) PLAN

     The Company has a defined  contribution plan (the "Concentra 401(k) Plan"),
formerly  the  Managed  Care  Services  401(k) Plan (the "MCS  Concentra  401(k)
Plan"),  pursuant  to which  employees  who are at least 21 years of age and who
have  completed  at least six months of service  are  eligible  to  participate.
Participants  in the  Concentra  401(k)  Plan may not  contribute  more than the
lesser  of a  specified  statutory  amount  or 15% of  his or her  pretax  total
compensation.   The  Concentra  401(k)  Plan  permits,  but  does  not  require,
additional  matching   contributions  of  up  to  50%  of  participants'  pretax
contributions  up to a maximum of 6% of compensation  by the Company.  Employees
are 100% vested in their own contributions while Company  contributions vest 20%
per year with  employees  being fully  vested  after five years.  For 1998,  the
Company  is  making  a  matching  contribution  of 50% of  participant's  pretax
contributions up to 4% of compensation.


(B) HEALTH SERVICES 401(K) PLAN

     Health Services'  defined  contribution  plan (the "HS 401(k) Plan") merged
into the  Concentra  401(k)  Plan as of July 1,  1998.  The HS  401(k)  Plan had
similar  terms to those of the  Concentra  401(k)  Plan.  There were no matching
contributions under the plan in 1996, 1997 and 1998.


(D) PPS 401(K) PLAN

     PPS'  defined  contribution  plan (the "PPS 401(k)  Plan")  merged into the
Concentra  401(k)  Plan as of August 1, 1998.  The PPS 401(k)  Plan had  similar
terms to those of the Concentra  401(k) Plan.  For the years ended  December 31,
1996 and 1997 and the  seven-month  period in 1998,  PPS elected to match 25% of
employee  contributions  up to 7% of gross  earnings.  The Company has  expensed
$910,000,  $1,053,000 and $1,508,000 for the years ended December 31, 1996, 1997
and 1998, respectively,  for matching contributions to the Concentra 401(k), the
MCS 401(k) and the PPS 401(k) Plans.
 


(12) STOCK PURCHASE PLAN AND STOCK OPTION PLANS


(A) CONCENTRA 1997 EMPLOYEE STOCK PURCHASE PLAN

     The Concentra 1997 Employee Stock Purchase Plan (the "1997 Purchase  Plan")
for employees of the Company  authorizes the issuance of up to 500,000 shares of
Common Stock  pursuant to the  exercise of  nontransferable  options  granted to
participating   employees.  The  1997  Purchase  Plan  is  administered  by  the
Compensation Committee of the Board of Directors.

     Under the terms of the 1997 Purchase  Plan, an employee must  authorize the
Company in writing to deduct an amount  (not less than 1% nor more than 15% of a
participant's base compensation and in any event not more than $25,000) from his
or her pay during six month  periods  commencing on January 1 and July 1 of each
year (each a "Purchase  Period").  The exercise price for shares purchased under
the 1997 Purchase Plan for each Purchase Period is the lesser of 85% of the fair
market  value of the  Common  Stock on the  first  or last  business  day of the
Purchase Period.  The fair market value will be the closing selling price of the
Common Stock as quoted.


(B) MANAGED CARE SERVICES AND HEALTH SERVICES EMPLOYEE STOCK PURCHASE PLANS

     Managed Care Services and Health Services each had employee stock purchase
plans under similar terms and conditions as those under the 1997 Purchase Plan.
 


                                      F-17

</TABLE>

(C) CONCENTRA 1997 LONG-TERM INCENTIVE PLAN

     Concentra  may grant  awards  with  respect to shares  under the  Company's
Long-term Incentive Plan (the "Concentra  Incentive Plan"). The awards under the
Concentra Incentive Plan include:  (i) incentive stock options qualified as such
under U.S.  federal  income tax laws,  (ii) stock options that do not qualify as
incentive  stock  options,  (iii)  stock  appreciation  rights  ("SARs"),   (iv)
restricted stock awards and (v) performance units.

     The number of shares of Common  Stock  that may be  subject to  outstanding
awards  under  the  Concentra  Incentive  Plan at any one  time is  equal to ten
percent of the total  number of  outstanding  shares of  Concentra  Common Stock
(treating as outstanding all shares of Common Stock issuable within 60 days upon
exercise  of  stock   options  or   conversion   or  exchange  of   outstanding,
publicly-traded  convertible or exchangeable  securities of Concentra) minus the
total number of shares of Common Stock subject to  outstanding  awards under the
Concentra  Incentive  Plan and any  future  stock-based  plan for  employees  or
directors of Company.  At December 31, 1998, the Company was authorized to award
grants of approximately 5,019,000 shares under the Concentra Incentive Plan. The
number of shares authorized under the Concentra Incentive Plan and the number of
shares  subject to an award under the Concentra  Incentive Plan will be adjusted
for stock splits, stock dividends, recapitalizations,  mergers and other changes
affecting the capital stock of Concentra.

     During 1997,  the Company  granted  restricted  stock for 357,000 shares of
Common Stock under the 1997  Incentive  Plan which were valued at  approximately
$9,903,000 based upon the market value of the shares at the time of issuance. As
of December 31, 1998,  93,000  shares of the  restricted  stock granted in 1997,
valued at  $2,806,000,  have been canceled due to  forfeiture.  During 1998, the
Company  granted  restricted  stock for 48,000  shares of Common Stock under the
1997 Incentive Plan which were valued at $1,413,000  based upon the market value
of the shares at the time of issuance.  The restricted stock grants vest 25% per
year beginning January 1, 2002. If the Company's  financial  performance exceeds
certain  established  performance  goals,  however,  the vesting of these shares
could accelerate whereby 33-1/3% of the shares could become vested on January 1,
2000 and each year  thereafter.  For the years ended December 31, 1997 and 1998,
the Company  recorded  amortization of $562,000 and $805,000,  respectively,  in
connection with the deferred  compensation  associated with the restricted stock
grants. During 1997 and 1998, the Company also granted 2,754 and 3,570 shares of
restricted stock to outside directors that vest over one year.

     After the 1997 Merger,  no additional awards were made under the former CRA
and  OccuSystems  stock  option  plans and only that  number of shares of Common
Stock  issuable  upon  exercise  of  awards  granted  under the  former  CRA and
OccuSystems  stock option plans as of the 1997 Merger were reserved for issuance
by the Company.

     In connection with the 1996 Transaction, PPS canceled all outstanding stock
options and  terminated  all  existing  stock  option  plans.  In return for the
cancellation of outstanding  options,  PPS made a cash payment to the holders of
these  options,  which  resulted  in  a  compensation  charge  of  approximately
$484,000.  Upon  the  cancellation  of the  options,  PPS  adopted  the 1996 PPS
Replacement  Stock Option Plan and the 1996 PPS Incentive  Stock Option Plan for
its key employees. The plan provided for the issuance of up to 325,000 shares of
PPS common stock.  The exercise price for the incentive  stock options could not
be less than the fair market  value of the  underlying  PPS common  stock on the
date of grant. After the merger, no additional awards were made under




                                      F-18



<PAGE>

the  former  PPS stock  option plans and outstanding PPS options were assumed by
the Concentra Incentive Plan  totaling approximately 580,000 shares of Concentra
common stock.

1997 and 1998 and changes  during the years then ended is presented in the table

(D) SFAS 123 DISCLOSURES


     The  Company  accounts  for these  plans  under APB No. 25,  under which no
compensation  cost has been  recognized  related  to stock  option  grants.  Had
compensation  cost for these plans been determined  consistent with Statement of
Financial   Accounting   Standards   No.  123,   "Accounting   for   Stock-Based
Compensation"  ("SFAS 123"),  the  Company's  net income,  pro forma net income,
earnings  per share and pro forma  earnings per share would have been reduced to

(1) Pro forma  net income and  basic and diluted  pro forma  earnings  per share
    for the years ended  December 31, 1996 and 1997 have been  calculated  as if
    PPS had been  subject  to  federal  and state  income  taxes for the  entire
    period,  based upon an effective tax rate  indicative of the statutory rates
    in effect.  Prior to its merger with the Company, PPS elected to be taxed as
    an S  corporation,  and  accordingly,  was not  subject to federal and state
    income taxes in certain jurisdictions.

     Because  the method of  accounting  under SFAS 123 has not been  applied to
options  granted prior to January 1, 1995, the resulting pro forma  compensation
cost  may  not be  representative  of  that  to be  expected  in  future  years.
Additionally,  the  1996,  1997 and 1998 pro  forma  amounts  include  $229,000,
$396,000 and $509,000,  respectively,  related to purchase  discounts offered on
employee  stock  purchase  plans.  The fair  value  of each  option  granted  is
estimated on the date of grant using the Black-Scholes option pricing model with
the following assumptions used for grants in 1996, 1997 and 1998, respectively:

(13) SEGMENT INFORMATION

     Operating segments represent  components of the Company's business that are
evaluated  regularly by key  management  in assessing  performance  and resource
allocation.  The Company has determined that its reportable  segments consist of
its Health  Services,  Specialized  Cost  Containment  and Field Case Management
Groups. The following are the reportable segments:

     Health  Services  manages  occupational  healthcare  centers  at  which  it
provides  support  personnel,  marketing,  information  systems  and  management
services to its affiliated  physicians.  Health  Services owns all the operating
assets of the occupational healthcare centers, including leasehold interests and
medical equipment.

     Specialized  Cost  Containment  services  include  first  report of injury,
utilization  management  (precertification  and concurrent review) retrospective
medical bill review, telephonic case management, preferred provider organization
("PPO") network access,  independent medical examinations ("IMEs"), peer reviews
and hospital bill  auditing.  These  services are designed to reduce the cost of
workers' compensation claims, automobile accident injury claims and group health
claims.


                                      F-20



<PAGE>

     Field Case Management  provides services involving case managers and nurses
working on a one-on-one  basis with injured  employees and their various  health
care  professionals,  employers  and  insurance  company  adjusters to assist in
maximizing medical improvement and, where appropriate, to expedite the return to
work.

     The Health Services Group is managed  separately and has different economic
characteristics  from the Specialized Cost Containment and Field Case Management
groups, and is therefore shown as a separate reportable segment.  The Field Case
Management Group and certain operating segments included in the Specialized Cost
Containment Groups have similar economic  characteristics and may share the same
management  and/or  locations.  However,  the  Field  Case  Management  Group is
reported  as a  separate  segment  for  management  reporting  purposes  and  it
represents 58.7%, 49.3% and 47.7% of total Managed Care Services revenue for the
years ended December 31, 1996, 1997 and 1998, respectively.

     Revenues from individual customers,  revenues between business segments and
revenues, operating profit and identifiable assets of foreign operations are not
significant.

     The  Company's  Statements  of  Operations on a segment basis for the years
ended December 31, 1996, 1997 and 1998 were as follows:

(14) SUBSEQUENT EVENTS

     On March 2, 1999,  Concentra  entered into a definitive  agreement to merge
(the "Merger") with Yankee Acquisition Corp. ("Yankee"), a corporation formed by
Welsh,  Carson,  Anderson & Stowe ("WCAS"),  a 14.8% stockholder of the Company.
Concentra's Board of Directors  unanimously  approved the transaction based upon
the recommendation of its special committee of the Board of Directors, which was
formed on October  29, 1998 to evaluate  strategic  alternatives  in response to
several unsolicited  expressions of interest regarding the possible  acquisition
of some or all of the  Company's  Common  Stock.  On March 24,  1999,  Concentra
entered  into an Amended and Restated  Agreement  and Plan of Merger with Yankee
(the "Amended  Merger  Agreement").  Pursuant to the Amended  Merger  Agreement,
Yankee  will  acquire  approximately  93% and funds  managed  by Ferrer  Freeman
Thompson & Co. ("FFT") will acquire  approximately 7% of the post-merger  shares
of common stock of the Company for $16.50 per share.  As a result of the Merger,
each  outstanding  share of Concentra  Common  Stock will be converted  into the
right to receive $16.50 in cash.

     In connection with the Merger,  effective March 2, 1999,  Concentra amended
its Rights Agreement.  The amendment  provides,  among other things, that Yankee
and its  affiliates  will not be deemed  an  Acquiring  Person  (as such term is
defined  in the Rights  Agreement)  and that the Rights  Agreement  will  expire
immediately prior to the effective time of the Merger.

     The transaction is valued at  approximately  $1,100,000,000,  including the
refinancing of $327,750,000 of the 6% and 4.5%  Convertible  Subordinated  Notes
which  contain  change in control  provisions  in the  related  indentures.  The
transaction  is  structured  to be accounted  for as a  recapitalization  and is
expected to be completed late in the second quarter of 1999. The  transaction is
conditioned upon, among other things, approval of the shareholders of Concentra,
receipt of financing and certain regulatory approvals.

     To finance the acquisition of the Company,  WCAS will invest  approximately
$350,000,000 in equity financing, including the value of shares already owned by
WCAS, and up to  $110,000,000 in subordinated  indebtedness.  Additionally,  FFT
will  invest  approximately  $30,000,000  in  equity.  WCAS  has  also  received
commitments  from various lenders to provide Yankee with  $190,000,000 in senior
subordinated notes, a $375,000,000 term loan and a $100,000,000 revolving credit
facility to replace the Company's existing Senior Credit Facility. Additionally,
Yankee would also utilize the  Company's  excess cash on hand at the time of the
merger to help  finance the  purchase  of the Common  Stock.  Subsequent  to the
exchange of shares for cash,  Yankee would merge with  Concentra  Managed  Care,
Inc. with Concentra Managed Care, Inc. surviving.

     As of March 26, 1999,  Concentra is aware of three  lawsuits that have been
filed by alleged  stockholders  of Concentra  relating to the Merger.  All three
lawsuits were filed in the Chancery Court for New Castle County,  Delaware. Each
of the lawsuits names  Concentra,  its directors and Yankee as  defendants.  The
plaintiff  in each  lawsuit  seeks to  represent a putative  class of all public
holders of Concentra common stock. The lawsuits allege, among other things, that
the  directors of  Concentra  breached  their  fiduciary  duties to  Concentra's
stockholders  by approving the Merger.  The lawsuits  seek,  among other things,
preliminary  and permanent  injunctive  relief


                                      F-22



<PAGE>

prohibiting consummation of the Merger, unspecified damages, attorneys' fees and
other relief. Concentra expects that these  lawsuits will be  consolidated  into
a single  action.  The Company intends to contest these lawsuits vigorously.

(1) Prior to its  recapitalization in March of 1994, CRA had elected to be taxed
    as an "S"  corporation.  In connection  with its  recapitalization,  CRA was
    required to change from an "S" to a "C" corporation. This change resulted in
    CRA  recording  an  incremental  tax  provision of  $3,772,000  in the first
    quarter of 1994. The Company's pro forma net income for 1994 would have been
    $3,466,000 higher had CRA had been subject to federal and state income taxes
    during the entire period based upon an effective tax rate  indicative of the
    statutory rate in effect during the period.

(2) Pro forma net income and basic and  diluted  pro forma  earnings  per share,
    where applicable, for the years ended December 31, 1994, 1995, 1996 and 1997
    have been  calculated as if PPS had been subject to federal and state income
    taxes for the entire period,  based upon an effective tax rate indicative of
    the  statutory  rates in effect.  Prior to its merger with the Company,  PPS
    elected to be taxed as an S corporation, and accordingly, was not subject to
    federal and state income taxes in certain jurisdictions.

(1) Pro forma net income (loss) and basic and diluted pro forma earnings  (loss)
    per share for the four quarters ended December 31, 1997 have been calculated
    as if PPS had been  subject to federal and state income taxes for the entire
    period,  based upon an effective tax rate  indicative of the statutory rates
    in effect.  Prior to its merger with the Company, PPS elected to be taxed as
    an S  corporation,  and  accordingly,  was not  subject to federal and state
    income taxes in certain jurisdictions.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULE


To the Stockholders and Board of
Directors of Concentra Managed Care, Inc.

We have audited in accordance with generally  accepted auditing  standards,  the
financial  statements of Concentra Managed Care, Inc. and have issued our report
thereon dated  February 2, 1999 (except with respect to the matter  discussed in
Note 14,  as to which the date is March  26,  1999).  Our audit was made for the
purpose  of forming an  opinion  on the basic  financial  statements  taken as a
whole. The schedule listed in the index of the financial  statement schedules is
presented  for the  purpose  of  complying  with  the  Securities  and  Exchange
Commission's  rules  and is not part of the  basic  financial  statements.  This
schedule has been subjected to the auditing  procedures  applied in the audit of
the  basic  financial  statements  and,  in our  opinion,  fairly  states in all
material  respects  the  financial  data  required  to be set forth  therein  in
relation to the basic financial statements taken as a whole.

     WHEREAS,  the Company and Executive have entered into a certain  Employment
Agreement, dated as of April 21, 1997 (the "Employment Agreement"); and

     WHEREAS,  the Company and Executive now desire to enter into this Amendment

         hereunder (1) for Good Reason and/or for Additional  Reason,  or (2) if

                           to a location  outside of the Boston,  Massachusetts,

                           office space within which Executive is to perform his
                           duties  and  responsibilities  hereunder  or  in  the
                           secretarial and  administrative  support  provided to

Employment Agreement is hereby amended by adding the following subsection (f) at
the end of such Section 6:

                  "(f)  Additional  Reason.  If Executive  shall  terminate  his
         employment for Additional Reason, as well as for Good Reason,  then, in
         addition to and not in lieu of any other amounts payable by the Company
         to Executive  whether  pursuant to Section 6(d) or otherwise  (it being
         the intention of the parties that,  upon the  occurrence of an event or
         events  described in the  definition or "Good  Reason" and  "Additional
         Reason" in Section 5(d),  Executive may  terminate  this  Agreement for
         Good Reason and for  Additional  Reason),  then the  Company  shall pay
         Executive  as  additional  severance  pay,  on or before  the fifth day
         following  the  Date  of  Termination,  a lump  sum in  cash  equal  to
         Executive's  full  annual Base Salary at the rate in effect at the time
         the  Notice  of  Termination  is given  (for a total  of two (2)  times
         Executive's  full annual Base Salary when combined with amounts payable
         pursuant to Section 6(d)(B)).

                  In addition,  (x) the Company  shall make payments of premiums
         as necessary to cause  Executive  and  Executive's  spouse and children
         under age twenty-five (25) to continue to be covered by the medical and
         dental  insurance as in effect at and as of the Date of Termination (or
         to provide as similar coverage as possible for the same premiums if the
         continuation of existing coverage is not permitted) for one (1) year in
         addition to the one (1) year  provided  for under  Section  6(d) (for a
         total of two (2) years) after the Date of Termination,  in each case to
         the extent such coverage is available."

         3. Other Provisions Relating to Termination.  Subsections 7(b) and 7(c)
of the  Employment  Agreement  are hereby  amended to read in their  entirety as
follows:

                  "(b) Date of  Termination.  For  purposes  of this  Agreement,
         "Date of  Termination"  shall mean:  (1) if  Executive's  employment is
         terminated  by his  death,  the date of his death;  (2) if  Executive's


                                       3

         employment  is terminated  because of a disability  pursuant to Section
         5(b),  then  thirty  (30) days  after  Notice of  Termination  is given
         (provided that Executive  shall not have returned to the performance of
         his duties on a full-time  basis  during such thirty (30) day  period);
         (3) if Executive's employment is terminated by the Company for Cause or
         by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
         subject to Sections 7(c) and 7(d),  the date specified in the Notice of
         Termination;  (4) if the Company  gives  Executive  notice  pursuant to
         Section 1 prior to any  anniversary of the date hereof that the Term of
         this Agreement  shall not be  automatically  extended for an additional
         year on any  such  anniversary  date,  the  date  upon  which  the Term
         expires; and (5) if Executive's  employment is terminated for any other
         reason, the date on which a Notice of Termination is given.

                  (c) Good Reason and/or Additional Reason.  Upon the occurrence
         of an event  described in clauses (A) through (E) of the  definition of
         "Good Reason" in Section 5(d),  and/or upon the  occurrence of an event
         described in clauses (A) through (D) of the  definition of  "Additional
         Reason"  in  Section  5(d),  Executive  may  terminate  his  employment
         hereunder  for Good Reason and/or  Additional  Reason,  as  applicable,
         within one hundred  eighty (180) days  thereafter by giving a Notice of
         Termination  to the  Company  to  that  effect.  If the  effect  of the
         occurrence  of the event giving rise to Good Reason  and/or  Additional
         Reason  under  Section  5(d) may be cured,  the Company  shall have the
         opportunity  to cure any such  effect for a period of thirty  (30) days
         following receipt of Executive's Notice of Termination.  If the Company
         fails to cure any such effect,  the  termination for Good Reason and/or
         Additional  Reason  shall  become  effective  on the date  specified in
         Executive's  Notice of  Termination.  If  Executive  does not give such
         Notice of Termination  to the Company,  then this Agreement will remain
         in  effect;  provided,  however,  that  the  failure  of  Executive  to
         terminate this Agreement for Good Reason and/or Additional Reason shall
         not be deemed a waiver of Executive's right to terminate his employment
         for Good  Reason  and/or  Additional  Reason upon the  occurrence  of a
         subsequent event described in Section 5(d) in accordance with the terms
         of this Agreement."

         4. No Change.  Except as  expressly  modified  hereby,  the  Employment
Agreement shall continue in effect unchanged.

follows:



                                       3

                  "(b) Date of  Termination.  For  purposes  of this  Agreement,
         "Date of  Termination"  shall mean:  (1) if  Executive's  employment is
         terminated  by his  death,  the date of his death;  (2) if  Executive's

         his duties on a full-time  basis  during such thirty (30) day  period);
         (3) if Executive's employment is terminated by the Company for Cause or
         by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
         subject to Sections 7(c) and 7(d),  the date specified in the Notice of
         Termination;  (4) if the Company  gives  Executive  notice  pursuant to
         Section 1 prior to any  anniversary of the date hereof that the Term of
         this Agreement  shall not be  automatically  extended for an additional
         year on any  such  anniversary  date,  the  date  upon  which  the Term
         expires; and (5) if Executive's  employment is terminated for any other
         reason, the date on which a Notice of Termination is given.

                  (c) Good Reason and/or Additional Reason.  Upon the occurrence
         of an event  described in clauses (A) through (E) of the  definition of
         "Good Reason" in Section 5(d),  and/or upon the  occurrence of an event
         described in clauses (A) through (D) of the  definition of  "Additional

         within one hundred  eighty (180) days  thereafter by giving a Notice of
         Termination  to the  Company  to  that  effect.  If the  effect  of the
         occurrence  of the event giving rise to Good Reason  and/or  Additional
         Reason  under  Section  5(d) may be cured,  the Company  shall have the
         opportunity  to cure any such  effect for a period of thirty  (30) days
         following receipt of Executive's Notice of Termination.  If the Company
         fails to cure any such effect,  the  termination for Good Reason and/or
         Additional  Reason  shall  become  effective  on the date  specified in
         Executive's  Notice of  Termination.  If  Executive  does not give such
         Notice of Termination  to the Company,  then this Agreement will remain
         in  effect;  provided,  however,  that  the  failure  of  Executive  to
         terminate this Agreement for Good Reason and/or Additional Reason shall
         not be deemed a waiver of Executive's right to terminate his employment
         for Good  Reason  and/or  Additional  Reason upon the  occurrence  of a
         subsequent event described in Section 5(d) in accordance with the terms
         of this Agreement."

Company or any of its  subsidiaries  or affiliates),  any  information  acquired
during  the  course  of  employment  hereunder  with  regard  to the  financial,

performance  by  Executive  of  his  duties  and   responsibilities   hereunder,
reasonably  necessary  or  appropriate  disclosure  to another  employee  of the
Company or to  representatives  or agents of the  Company  (such as  independent
public  accountants  and legal  counsel);  (B) at the express  direction  of any
authorized  governmental  entity;  (C)  pursuant  to a subpoena  or other  court
process; (D) as otherwise required by law or the rules,  regulations,  or orders
of any applicable regulatory body; or (E) as otherwise necessary, in the opinion
of counsel for  Executive,  to be disclosed by Executive in connection  with the
prosecution of any legal action or proceeding initiated by Executive against the
Company or any  subsidiary  or  affiliate  of the  Company or the defense of any

                                       2

<PAGE>


Company. Executive shall, at any time requested by the Company (either during or
after his  employment  with the  Company),  promptly  deliver to the Company all
memoranda,  notes, reports,  lists, and other documents (and all copies thereof)
relating to the business of the Company or any of its subsidiaries or affiliates
which he may then possess or have under his control.

         3.       Compensation and Related Matters.

                  (a) Base Salary. Executive shall receive a base salary paid by
the Company ("Base Salary") at the annual rate of Four Hundred  Thousand Dollars
($400,000) during each calendar year of the Term, payable in substantially equal
monthly  installments  (or such other more  frequent  times as executives of the
Company  normally are paid).  In addition,  the Company's  Board of Directors or
Option and  Compensation  Committee  of the Board of  Directors  shall,  in good
faith,  consider granting  increases in the Base Salary based on such factors as
Executive's  performance and the growth and/or profitability of the Company, but
the Company shall have no obligation to grant such increases in compensation.

                  (b) Bonus Payments. Executive shall be entitled to receive, in
addition  to the Base  Salary,  such  bonus  payments,  if any,  as the Board of
Directors or the Option and Compensation Committee of the Board of Directors may
specify.

                  (c)  Expenses.  During the term of his  employment  hereunder,
Executive shall be entitled to receive prompt  reimbursement  for all reasonable
expenses  incurred  by him (in  accordance  with  the  policies  and  procedures
established  by the Board of  Directors  for its senior  executive  officers) in
performing  services  hereunder,   provided  that  Executive  properly  accounts
therefor in accordance with Company policy.

                  (d) Other Benefits.  The Company shall not make any changes in
any employee benefit plans or other arrangements in effect on the date hereof or
subsequently  in  effect  in  which   Executive   currently  or  in  the  future
participates (including,  without limitation,  each pension and retirement plan,
supplemental pension and retirement plan, savings and profit sharing plan, stock
or unit ownership plan,  stock or unit purchase plan, stock or unit option plan,
life insurance plan,  medical  insurance  plan,  disability  plan,  dental plan,
health-and-accident  plan, or any other similar plan or arrangement)  that would
adversely affect Executive's rights or benefits  thereunder,  unless such change
occurs  pursuant to a program  applicable  to all  executives of the Company and
does not  result in a  proportionately  greater  reduction  in the  rights of or
benefits to  Executive  as compared  with any other  executive  of the  Company.
Executive  shall be entitled to  participate  in or receive  benefits  under any
employee benefit plan or other  arrangement made available by the Company now or
in the future to its senior  executive  officers and key  management  employees,
subject to and on a basis  consistent  with the terms,  conditions,  and overall
administration of such plan or arrangement.  Nothing paid to Executive under any
plan or arrangement presently in effect or made available in the future shall be
deemed  to be in lieu of the  Base  Salary  payable  to  Executive  pursuant  to
paragraph (a) of this Section 3.

                  (e) Vacations. Executive shall be entitled to twenty (20) paid
vacation days in


                                       3


<PAGE>

each calendar year commencing, or such additional number as may be determined by
the Board of Directors  from time to time.  For  purposes of this Section  3(e),
weekends  shall not count as vacation days and Executive  shall also be entitled
to all paid holidays given by the Company to its senior executive officers.

                  (f)  Perquisites.  Executive  shall be entitled to receive the
perquisites and fringe benefits appertaining to senior executive officers of the
Company in accordance  with any practice  established by the Board of Directors.
In  the  event  Executive's  employment  hereunder  is  terminated  (whether  by
Executive  or the  Company) for any reason  whatsoever  (other than  Executive's
death), then the Company shall, at Executive's written request and to the extent
permitted by the terms of such policies and applicable law, assign and convey to
Executive any life insurance  policies  maintained by the Company on the life of
Executive,  who shall thereafter be solely responsible,  at his election, to pay
all  premiums  payable  after such  assignment  and  conveyance  to maintain the
coverage under such policies with respect to Executive.  Executive  shall not be
required  to pay any  money or other  consideration  to the  Company  upon  such
assignment  and  conveyance,  it being  acknowledged  and agreed by the  parties
hereto that Executive's  execution and delivery hereof  constitute  adequate and
satisfactory consideration for such assignment and conveyance.

                  (g) Proration.  Any payments or benefits  payable to Executive
hereunder in respect of any calendar year during which  Executive is employed by
the  Company for less than the entire  year,  unless  otherwise  provided in the
applicable plan or arrangement,  shall be prorated in accordance with the number
of days in such calendar year during which he is so employed.

         4. Executive's Office and Relocation. Executive shall primarily perform
his duties and  responsibilities  hereunder at the Company's  offices located at
312 Union Wharf, Boston, Massachusetts (or at such other location in the Boston,
Massachusetts, metropolitan area to which the Company may in the future relocate
such principal executive offices),  except for reasonable required travel on the
Company's  business.  If the  Company  requests  Executive  to  report  for  the
performance  of his services  hereunder  on a regular or permanent  basis at any
location  or office  more than  thirty-five  (35)  miles  from 312 Union  Wharf,
Boston,  Massachusetts,  and Executive agrees to such change,  the Company shall
pay Executive's  reasonable relocation and moving expenses,  including,  but not
limited to, the cost of moving his immediate  family,  expenses  incurred  while
seeking new  housing  (including  travel by  Executive's  spouse) and  temporary
living expenses incurred by Executive or his family for up to one hundred eighty
(180) days.

         5. Termination.  Executive's  employment hereunder may be terminated by
the Company or Executive,  as applicable,  without any breach of this Agreement,
only under the following circumstances.

                  (a) Death. Executive's  employment  hereunder shall  terminate
                      upon his death.

                  (b) Disability.  If, as a result of Executive's incapacity due
to physical or mental illness, Executive shall have been unable, with reasonable
accommodation,   to  perform  the


                                       4
<PAGE>

essential functions of his duties and responsibilities  hereunder on a full time
basis for one hundred eighty (180) consecutive  calendar days, and within thirty
(30) days after written  notice of  termination is given (which may occur before
or after the end of such one hundred  eighty (180) day period)  Executive  shall
not have  returned to the  performance  of his  material  managerial  duties and
responsibilities  hereunder  on a full time basis,  the  Company  may  terminate
Executive's employment hereunder.

                           hereunder (other than any such failure resulting from
                           Executive's  incapacity  due to  physical  or  mental
                           illness  or any such  actual or  anticipated  failure
                           after the  issuance  of a Notice of  Termination  for
                           Good Reason (as hereinafter defined) by Executive);

                  (2)      The commission by Executive of dishonesty or fraud of

                           of his duties hereunder, intentional violation of law
                           or  governmental  regulation of a material  nature in
                           connection   with  the   performance  of  his  duties
                           hereunder,  or willful or intentional misconduct of a

                           a  final  adjudication  of  any  board,  institution,
                           organization  or   governmental   agency  having  any
                           privilege  or  right  to pass  upon  the  conduct  of
                           Executive;

                  (5)      The   continued   breach  by   Executive  of  any  of
                           Executive's    material    obligations   under   this
                           Agreement.

         Reason,  or (2) if his health should become  impaired to an extent that
         makes the continued  performance of his duties  hereunder  hazardous to
         his physical or mental health or his life.

                           that is  determined  by Executive in good faith to be

                           Executive;

                  (D)      the relocation of  Executive's  office at which he is

                           to a location  outside of the Boston,  Massachusetts,
                           metropolitan area, or a materially adverse alteration
                           in the office  space  within  which  Executive  is to

                           material  term or  provision  hereof  or of any other
                           written  agreement  between Executive and the Company
                           or any such subsidiary or affiliate.

         6. Compensation  Upon Termination or Failure to Renew.  Executive shall
be entitled to the following  compensation from the Company upon the termination
of his employment or upon the Company's delivery of notice pursuant to Section 1
that the Term of this Agreement  shall not following any anniversary of the date
hereof be automatically extended for an additional year.

                  (a) Death.  If Executive's  employment  shall be terminated by
reason of his death,  the  Company  shall pay to such  person as shall have been
designated in a notice filed with the Company prior to Executive's death, or, if
no such person shall be designated,  to his estate as a death benefit,  his Base
Salary to the date of his death in addition to any payments  Executive's spouse,
beneficiaries,  or estate may be entitled to receive  pursuant to any pension or
employee benefit plan or other  arrangement or life insurance policy  maintained
by the Company. In addition,  (x) the Company shall make payments of premiums to
continue the medical and dental  insurance  coverage of  Executive's  spouse and
children  under  age  twenty-five  (25) as in  effect  at and as of the  date of
Executive's  death (or to provide as similar  coverage as possible  for the same
premiums if the continuation of existing  coverage is not permitted) for two (2)
years  after the date of  Executive's  death,  in each case to the  extent  such
coverage is available, and (y) the Company shall make a lump sum cash payment to
the appropriate  insurance  company(ies)  in an amount  sufficient to fully fund
future premium  payments  pursuant to Executive's  then existing  second-to-die,
split-dollar   insurance   policy(ies)   obtained  through  the  Company  and/or
OccuSystems, Inc.

                  (b)  Disability.  During any period  that  Executive  fails to
perform his  material  managerial  duties and  responsibilities  hereunder  as a
result of incapacity due to physical or mental illness, Executive shall continue
to receive his Base Salary and any bonus payments until  Executive's  employment
is terminated pursuant to Section 5(b) hereof or until Executive  terminates his
employment  pursuant to Section  5(d)(2) hereof,  whichever first occurs.  After
such termination, the Company shall pay to Executive, on or before the fifth day
following the Date of Termination  (as  hereinafter  defined) his Base Salary to
the Date of  Termination.  In addition,  (x) the Company  shall make payments of
premiums as necessary to cause  Executive  and  Executive's 



                                       7

spouse and children under age twenty-five  (25) to continue to be covered by the
medical and dental  insurance as in effect at and as of the Date of  Termination
(or to provide as similar  coverage  as  possible  for the same  premiums if the
continuation of existing  coverage is not permitted) for two (2) years after the
Date of Termination,  in each case to the extent such coverage is available, and
(y) the Company shall make a lump sum cash payment to the appropriate  insurance
company(ies)  in an amount  sufficient  to fully fund  future  premium  payments
pursuant to  Executive's  then existing  second-to-die,  split-dollar  insurance
policy(ies) obtained through the Company and/or OccuSystems, Inc.

                  (c) Cause. If Executive's  employment  shall be terminated for
Cause,  the Company  shall pay  Executive  his Base  Salary  through the Date of
Termination  at the rate in effect at the time Notice of  Termination  is given.
Such payments shall fully discharge the Company's obligations hereunder.

                  (d) Breach by the Company, for Good Reason, or Upon Failure to
Renew.  If  (1) in  breach  of  this  Agreement,  the  Company  shall  terminate
Executive's  employment  (it being  understood  that a purported  termination of
Executive's  employment  by the  Company  pursuant  to  any  provision  of  this
Agreement that is disputed and finally  determined not to have been proper shall
be a termination by the Company in breach of this  Agreement),  or (2) Executive
shall  terminate his employment  for Good Reason,  or (3) the Company shall give
Executive  notice  pursuant  to Section 1 prior to any  anniversary  of the date
hereof that the Term of this Agreement shall not be  automatically  extended for
an  additional  year on any such  anniversary  date,  then the Company shall pay
Executive:

         (A)      his Base Salary through the Date of Termination at the rate in
                  effect at the time Notice of Termination is given;

         (B)      in  lieu of any  further  salary  payments  to  Executive  for
                  periods  subsequent  to the Date of  Termination,  the Company
                  shall pay as severance pay to Executive on or before the fifth
                  day  following  the  Date of  Termination,  a lump sum in cash
                  equal to two (2) times  Executive's full annual Base Salary at
                  the rate in effect at the time the  Notice of  Termination  is
                  given; and

         (C)      all benefits  payable under the terms of any employee  benefit
                  plan or other arrangement as of the Date of Termination.

                  In addition,  (x) the Company  shall make payments of premiums
as necessary to cause  Executive and  Executive's  spouse and children under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage is not permitted) for two (2) years after the Date of  Termination,  in
each case to the extent such  coverage is  available,  and (y) the Company shall
make a lump sum cash payment to the  appropriate  insurance  company(ies)  in an
amount  sufficient to fully fund future premium

                                       8

<PAGE>

payments  pursuant to  Executive's  then  existing  second-to-die,  split-dollar
insurance policy(ies) obtained through the Company and/or OccuSystems, Inc.

                  (e)  Mitigation.  Executive  shall not be required to mitigate
the  amount of any  payment  provided  for in this  Section 6 by  seeking  other
employment  or  otherwise,  nor shall the amount of any payment  provided for in
this Section 6 be reduced by any compensation  earned by Executive as the result
of employment by another employer after the Date of Termination, or otherwise.

                  (f)  Additional  Reason.  If  Executive  shall  terminate  his
employment for Additional Reason, as well as for Good Reason,  then, in addition
to and not in lieu of any other  amounts  payable by the  Company  to  Executive
whether  pursuant to Section  6(d) or otherwise  (it being the  intention of the
parties  that,  upon  the  occurrence  of an event or  events  described  in the
definition or "Good Reason" and "Additional  Reason" in Section 5(d),  Executive
may terminate this Agreement for Good Reason and for  Additional  Reason),  then
the Company shall pay Executive as  additional  severance  pay, on or before the
fifth  day  following  the  Date of  Termination,  a lump  sum in cash  equal to
one-half (1/2) of  Executive's  full annual Base Salary at the rate in effect at
the time the Notice of  Termination is given (for a total of two and one-half (2
1/2) times  Executive's  full  annual Base Salary  when  combined  with  amounts
payable pursuant to Section 6(d)(B)).

                  In addition,  (x) the Company  shall make payments of premiums
as necessary to cause  Executive and  Executive's  spouse and children under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage is not  permitted)  for six (6) months in addition to the two (2) years
provided for under  Section 6(d) (for a total of two and one-half (2 1/2) years)
after the Date of  Termination,  in each case to the  extent  such  coverage  is
available.

         7.       Other Provisions Relating to Termination.

                  (a) Notice of  Termination.  Any  termination  of  Executive's
employment by the Company or by Executive (other than termination because of the
death of Executive)  shall be  communicated  by written Notice of Termination to
the  other  party  hereto.  For  purposes  of  this  Agreement,   a  "Notice  of
Termination"  shall mean a notice which shall indicate the specific  termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and  circumstances  claimed  to  provide  a basis for  termination  of
Executive's employment under the provision so indicated.

                  (b) Date of Termination. For purposes of this Agreement, "Date
of Termination"  shall mean: (1) if Executive's  employment is terminated by his
death,  the date of his  death;  (2) if  Executive's  employment  is  terminated
because of a disability  pursuant to Section  5(b),  then thirty (30) days after
Notice of Termination is given  (provided that Executive shall not have returned
to the  performance  of his duties on a full-time  basis during such thirty (30)
day period);  (3) if  Executive's  employment  is  terminated by the Company for
Cause or by  Executive


                                       9

<PAGE>

for Good Reason and/or for Additional Reason, then, subject to Sections 7(c) and
7(d), the date specified in the Notice of Termination;  (4) if the Company gives
Executive  notice  pursuant  to Section 1 prior to any  anniversary  of the date
hereof that the Term of this Agreement shall not be  automatically  extended for
an additional  year on any such  anniversary  date, the date upon which the Term
expires;  and (5) if Executive's  employment is terminated for any other reason,
the date on which a Notice of Termination is given.

                  (c) Good Reason and/or Additional Reason.  Upon the occurrence
of an event  described  in clauses (A) through  (E) of the  definition  of "Good
Reason" in Section 5(d),  and/or upon the  occurrence  of an event  described in
clauses (A)  through (D) of the  definition  of  "Additional  Reason" in Section
5(d),  Executive may terminate his  employment  hereunder for Good Reason and/or
Additional  Reason,  as  applicable,   within  one  hundred  eighty  (180)  days
thereafter by giving a Notice of Termination  to the Company to that effect.  If
the effect of the  occurrence  of the event  giving rise to Good  Reason  and/or
Additional  Reason under  Section 5(d) may be cured,  the Company shall have the
opportunity  to cure any such effect for a period of thirty (30) days  following
receipt of Executive's  Notice of Termination.  If the Company fails to cure any
such effect,  the  termination  for Good Reason and/or  Additional  Reason shall
become effective on the date specified in Executive's Notice of Termination.  If
Executive  does not give such Notice of  Termination  to the Company,  then this
Agreement  will  remain  in  effect;  provided,  however,  that the  failure  of
Executive to terminate this Agreement for Good Reason and/or  Additional  Reason
shall not be deemed a waiver of  Executive's  right to terminate his  employment
for Good Reason  and/or  Additional  Reason upon the  occurrence of a subsequent
event described in Section 5(d) in accordance with the terms of this Agreement.

                  (d) Cause.  In the case of any  termination  of Executive  for
Cause,  the Company will give  Executive a Notice of  Termination  describing in
reasonable  detail,  the  facts  or  circumstances  giving  rise to  Executive's
termination  (and,  if  applicable,  the action  required to cure same) and will
permit  Executive  thirty  (30) days to cure such  failure to comply or perform.
Cause  for  Executive's  termination  will  not be  deemed  to exist  until  the
expiration of the foregoing cure period,  so long as Executive  continues to use
his best efforts  during the cure period to cure such failure.  If within thirty
(30) days following Executive's receipt of a Notice of Termination for Cause (1)
Executive  delivers written notice to the Company denying that Cause exists, the
question  of the  existence  or  nonexistence  of Cause  will be  submitted  for
arbitration in accordance with Section 10; or (2) if Executive has not cured the
facts or  circumstances  giving rise to  Executive's  termination  for Cause and
shall not have  delivered a notice  pursuant to clause (1) of this Section 7(d),
then  Executive's  termination  for  Cause  shall  be  effective  as of the date
specified in the Notice of Termination.

                  (e) Interest.  Until paid, all past due amounts required to be
paid by the Company under any provision of this Agreement shall bear interest at
the highest  non-usurious rate permitted by applicable federal,  state, or local
law.

                  (a)  Successors.  This  Agreement  shall be binding upon,  and
inure  to  the  benefit  of,  the  Company,   Executive,  and  their  respective
successors,   assigns,   personal   and   legal   representatives,    executors,
administrators, heirs, distributees, devisees, and legatees, as applicable.

                  (b)  Assumption.   The  Company  will  require  any  successor
(whether direct or indirect, by purchase of securities,  merger,  consolidation,
sale of assets,  or  otherwise) to all or  substantially  all of the business or
assets  of the  Company,  by an  agreement  in  form  and  substance  reasonably
satisfactory  to Executive,  to expressly  assume this Agreement and to agree to
perform  this  Agreement  in the same  manner  and to the same  extent  that the
Company would be required to perform it if no such  succession  had taken place.
Failure of the Company to obtain such agreement  prior to the  effectiveness  of
any such  succession  shall be a breach  of this  Agreement  and  shall  entitle
Executive  to  compensation  from the Company in the same amount and on the same
terms as he would be entitled to hereunder if he terminated  his  employment for
Good Reason, except that for purposes of implementing the foregoing, the date on
which  any  such  succession  becomes  effective  shall  be  deemed  the Date of
Termination.

                  (c)  Certain  Payments.  If  Executive  should  die  while any
amounts would still be payable to him hereunder if he had continued to live, all
such amounts, unless otherwise provided herein, shall be paid in accordance with
the terms of this Agreement to Executive's  devisee,  legatee, or other designee
or, if there be no such designee, to Executive's estate.

         10. Disputes. In the event any dispute or controversy arises under this
Agreement and is not resolved by mutual written  agreement between Executive and
the Company  within thirty (30) days after notice of the dispute is first given,
then,  upon the written  request of Executive  or the  Company,  such dispute or
controversy  shall be  submitted  to  arbitration,  which  arbitration  shall be
conducted in accordance with the rules of the American Arbitration  Association.
Judgment may be entered  thereon and the results of arbitration  will be binding
and conclusive on the parties hereto.  Any arbitrator's  award or finding or any
judgment or verdict  thereon will be final and  unappealable.  All parties agree
that venue for arbitration  will be in the city specified in Section 4, and that
any arbitration  commenced in any other venue will be transferred to such venue,
upon the written  request of any party to this Agreement.  The prevailing  party
will be entitled to reimbursement for reasonable attorneys fees, costs, or other
expenses  pertaining to the  arbitration  and the  enforcement  thereof and such
attorneys  fees,  costs,  or other  expenses  shall  become a part of any award,
judgment,  or verdict.  All arbitrations will have three  individuals  acting as
arbitrators:  one arbitrator will be selected by Executive,  one arbitrator will
be selected by the Company,  and the two  arbitrators  so selected will select a
third  arbitrator.  Any  arbitrator  selected by a party will not be  affiliated
with,  associated with, or related to the party selecting that arbitrator in any
matter  whatsoever.  The  decision of the  majority of the  arbitrators  will be
binding on all parties.

         11.  Miscellaneous.  No  provision of this  Agreement  may be modified,
waived, or discharged unless such waiver,  modification,  or discharge is agreed
to in a written  instrument  signed by Executive  and the Company.  No waiver by
either party hereto of, or compliance  with,  any condition or provision of this
Agreement  to be  performed  by such  other  party  shall be  deemed a waiver of
similar or  dissimilar  provisions  or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation,  construction,  and  performance  of  this  Agreement  shall  be
governed  by the laws of the  State of  Delaware,  excluding  any  choice-of-law
provisions thereof.

         12.  Attorney  Fees.  Except as  otherwise  provided in Section 10, all
legal fees and costs incurred by Executive in connection  with the resolution of
any dispute or controversy  under or in connection  with this Agreement shall be
reimbursed  by the Company to Executive as bills for such services are presented
by Executive to the Company, unless such dispute or controversy is found to have
been  brought  not in good  faith  or  without  merit  by a court  of  competent
jurisdiction.

         NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  mutual
covenants  and  agreements  contained  herein  and for other  good and  valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the

         Section 7(c), and at his option, Executive may terminate his employment
         hereunder (1) for Good Reason and/or for Additional  Reason,  or (2) if

                           intersection  of Dallas  North  Tollway and  Beltline
                           Road,   Dallas,   Texas,  or  a  materially   adverse
                           alteration in the office space within which Executive
                           is  to  perform   his  duties  and   responsibilities
                           hereunder or in the  secretarial  and  administrative
                           support provided to Executive; or

                  (E)      a  failure  by  the  Company  or  any  subsidiary  or

                           is generally an essential  function of such  position
                           and which is determined by Executive in good faith to
                           be adverse to those existing before such change;

                  (B)      a reduction in  Executive's  Base Salary or any other
                           failure  by the  Company  to  comply  with  Section 3

                  (C)      the relocation of  Executive's  office at which he is
                           to perform his duties and responsibilities  hereunder
                           to  a  location   outside  of  the   Dallas,   Texas,
                           metropolitan area, or a materially adverse alteration
                           in the office  space  within  which  Executive  is to
                           perform his duties and responsibilities  hereunder or
                           in  the   secretarial  and   administrative   support
                           provided to Executive; or

                  (D)      a  failure  by  the  Company  or  any  subsidiary  or
                           affiliate  of the  Company  to comply  with any other
                           material  term or  provision  hereof  or of any other
                           written  agreement  between Executive and the Company
                           or any such subsidiary or affiliate."

         2. Compensation Upon Termination or Failure to Renew.  Section 6 of the
Employment Agreement is hereby amended by adding the following subsection (f) at
the end of such Section 6:

                  "(f)  Additional  Reason.  If Executive  shall  terminate  his
         employment for Additional Reason, as well as for Good Reason,  then, in
         addition to and not in lieu of any other amounts payable by the Company
         to Executive  whether  pursuant to Section 6(d) or otherwise  (it being
         the intention of the parties that,  upon the  occurrence of an event or
         events  described in the  definition or "Good  Reason" and  "Additional
         Reason" in Section 5(d),  Executive may  terminate  this  Agreement for
         Good Reason and for  Additional  Reason),  then the  Company  shall pay
         Executive  as  additional  severance  pay,  on or before  the fifth day
         following  the  Date  of  Termination,  a lump  sum in  cash  equal  to
         Executive's  full  annual Base Salary at the rate in effect at the time
         the  Notice  of  Termination  is given  (for a total  of two (2)  times
         Executive's  full annual Base Salary when combined with amounts payable
         pursuant to Section 6(d)(B)).

                  In addition,  (x) the Company  shall make payments of premiums
         as necessary to cause  Executive  and  Executive's  spouse and children
         under age twenty-five (25) to continue to be covered by the medical and
         dental  insurance as in effect at and as of the Date of Termination (or
         to provide as similar coverage as possible for the same premiums if the
         continuation of existing coverage is not permitted) for one (1) year in
         addition to the one (1) year  provided  for under  Section  6(d) (for a
         total of two (2) years) after the Date of Termination,  in each case to
         the extent such coverage is available."

         3. Other Provisions Relating to Termination.  Subsections 7(b) and 7(c)
of the  Employment  Agreement  are hereby  amended to read in their  entirety as
follows:


                                       3

<PAGE>

                  "(b) Date of  Termination.  For  purposes  of this  Agreement,
         "Date of  Termination"  shall mean:  (1) if  Executive's  employment is
         terminated  by his  death,  the date of his death;  (2) if  Executive's
         employment  is terminated  because of a disability  pursuant to Section
         5(b),  then  thirty  (30) days  after  Notice of  Termination  is given
         (provided that Executive  shall not have returned to the performance of
         his duties on a full-time  basis  during such thirty (30) day  period);
         (3) if Executive's employment is terminated by the Company for Cause or
         by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
         subject to Sections 7(c) and 7(d),  the date specified in the Notice of
         Termination;  (4) if the Company  gives  Executive  notice  pursuant to
         Section 1 prior to any  anniversary of the date hereof that the Term of
         this Agreement  shall not be  automatically  extended for an additional
         year on any  such  anniversary  date,  the  date  upon  which  the Term
         expires; and (5) if Executive's  employment is terminated for any other
         reason, the date on which a Notice of Termination is given.

                  (c) Good Reason and/or Additional Reason.  Upon the occurrence
         of an event  described in clauses (A) through (E) of the  definition of
         "Good Reason" in Section 5(d),  and/or upon the  occurrence of an event
         described in clauses (A) through (D) of the  definition of  "Additional
         Reason"  in  Section  5(d),  Executive  may  terminate  his  employment
         hereunder  for Good Reason and/or  Additional  Reason,  as  applicable,
         within one hundred  eighty (180) days  thereafter by giving a Notice of
         Termination  to the  Company  to  that  effect.  If the  effect  of the
         occurrence  of the event giving rise to Good Reason  and/or  Additional
         Reason  under  Section  5(d) may be cured,  the Company  shall have the
         opportunity  to cure any such  effect for a period of thirty  (30) days
         following receipt of Executive's Notice of Termination.  If the Company
         fails to cure any such effect,  the  termination for Good Reason and/or
         Additional  Reason  shall  become  effective  on the date  specified in
         Executive's  Notice of  Termination.  If  Executive  does not give such
         Notice of Termination  to the Company,  then this Agreement will remain
         in  effect;  provided,  however,  that  the  failure  of  Executive  to
         terminate this Agreement for Good Reason and/or Additional Reason shall
         not be deemed a waiver of Executive's right to terminate his employment
         for Good  Reason  and/or  Additional  Reason upon the  occurrence  of a
         subsequent event described in Section 5(d) in accordance with the terms
         of this Agreement."

         4. No Change.  Except as  expressly  modified  hereby,  the  Employment
Agreement shall continue in effect unchanged.

                  "(b) Date of  Termination.  For  purposes  of this  Agreement,
         "Date of  Termination"  shall mean:  (1) if  Executive's  employment is
         terminated  by his  death,  the date of his death;  (2) if  Executive's
         employment  is terminated  because of a disability  pursuant to Section
         5(b),  then  thirty  (30) days  after  Notice of  Termination  is given
         (provided that Executive  shall not have returned to the performance of
         his duties on a full-time  basis  during such thirty (30) day  period);
         (3) if Executive's employment is terminated by the Company for Cause or
         by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
         subject to Sections 7(c) and 7(d),  the date specified in the Notice of
         Termination;  (4) if the Company  gives  Executive  notice  pursuant to
         Section 1 prior to any  anniversary of the date hereof that the Term of
         this Agreement  shall not be  automatically  extended for an additional
         year on any  such  anniversary  date,  the  date  upon  which  the Term
         expires; and (5) if Executive's  employment is terminated for any other
         reason, the date on which a Notice of Termination is given.

                  (c) Good Reason and/or Additional Reason.  Upon the occurrence
         of an event  described in clauses (A) through (E) of the  definition of
         "Good Reason" in Section 5(d),  and/or upon the  occurrence of an event
         described in clauses (A) through (D) of the  definition of  "Additional
         Reason"  in  Section  5(d),  Executive  may  terminate  his  employment
         hereunder  for Good Reason and/or  Additional  Reason,  as  applicable,
         within one hundred  eighty (180) days  thereafter by giving a Notice of
         Termination  to the  Company  to  that  effect.  If the  effect  of the
         occurrence  of the event giving rise to Good Reason  and/or  Additional
         Reason  under  Section  5(d) may be cured,  the Company  shall have the
         opportunity  to cure any such  effect for a period of thirty  (30) days
         following receipt of Executive's Notice of Termination.  If the Company
         fails to cure any such effect,  the  termination for Good Reason and/or
         Additional  Reason  shall  become  effective  on the date  specified in
         Executive's  Notice of  Termination.  If  Executive  does not give such
         Notice of Termination  to the Company,  then this Agreement will remain
         in  effect;  provided,  however,  that  the  failure  of  Executive  to
         terminate this Agreement for Good Reason and/or Additional Reason shall
         not be deemed a waiver of Executive's right to terminate his employment
         for Good  Reason  and/or  Additional  Reason upon the  occurrence  of a
         subsequent event described in Section 5(d) in accordance with the terms
         of this Agreement."

         4. No Change.  Except as  expressly  modified  hereby,  the  Employment
Agreement shall continue in effect unchanged.

         Reason" in Section 5(d),  Executive may  terminate  this  Agreement for

         Executive's  full annual Base Salary when combined with amounts payable
         pursuant to Section 6(d)(B)).

                  In addition,  (x) the Company  shall make payments of premiums
         as necessary to cause  Executive  and  Executive's  spouse and children
         under age twenty-five (25) to continue to be covered by the medical and
         dental  insurance as in effect at and as of the Date of Termination (or
         to provide as similar coverage as possible for the same premiums if the
         continuation of existing coverage is not permitted) for one (1) year in
         addition to the one (1) year  provided  for under  Section  6(d) (for a
         total of two (2) years) after


                                       3

<PAGE>

         the Date of Termination,  in  each  case to the extent such coverage is
         available."

         3. Other Provisions Relating to Termination.  Subsections 7(b) and 7(c)
of the  Employment  Agreement  are hereby  amended to read in their  entirety as
follows:

                  "(b) Date of  Termination.  For  purposes  of this  Agreement,
         "Date of  Termination"  shall mean:  (1) if  Executive's  employment is
         terminated  by his  death,  the date of his death;  (2) if  Executive's
         employment  is terminated  because of a disability  pursuant to Section
         5(b),  then  thirty  (30) days  after  Notice of  Termination  is given
         (provided that Executive  shall not have returned to the performance of
         his duties on a full-time  basis  during such thirty (30) day  period);
         (3) if Executive's employment is terminated by the Company for Cause or
         by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
         subject to Sections 7(c) and 7(d),  the date specified in the Notice of
         Termination;  (4) if the Company  gives  Executive  notice  pursuant to
         Section 1 prior to any  anniversary of the date hereof that the Term of
         this Agreement  shall not be  automatically  extended for an additional
         year on any  such  anniversary  date,  the  date  upon  which  the Term
         expires; and (5) if Executive's  employment is terminated for any other
         reason, the date on which a Notice of Termination is given.

                  (c) Good Reason and/or Additional Reason.  Upon the occurrence
         of an event  described in clauses (A) through (E) of the  definition of
         "Good Reason" in Section 5(d),  and/or upon the  occurrence of an event
         described in clauses (A) through (D) of the  definition of  "Additional
         Reason"  in  Section  5(d),  Executive  may  terminate  his  employment
         hereunder  for Good Reason and/or  Additional  Reason,  as  applicable,
         within one hundred  eighty (180) days  thereafter by giving a Notice of
         Termination  to the  Company  to  that  effect.  If the  effect  of the
         occurrence  of the event giving rise to Good Reason  and/or  Additional
         Reason  under  Section  5(d) may be cured,  the Company  shall have the
         opportunity  to cure any such  effect for a period of thirty  (30) days
         following receipt of Executive's Notice of Termination.  If the Company
         fails to cure any such effect,  the  termination for Good Reason and/or
         Additional  Reason  shall  become  effective  on the date  specified in
         Executive's  Notice of  Termination.  If  Executive  does not give such
         Notice of Termination  to the Company,  then this Agreement will remain
         in  effect;  provided,  however,  that  the  failure  of  Executive  to
         terminate this Agreement for Good Reason and/or Additional Reason shall
         not be deemed a waiver of Executive's right to terminate his employment
         for Good  Reason  and/or  Additional  Reason upon the  occurrence  of a
         subsequent event described in Section 5(d) in accordance with the terms
         of this Agreement."
